Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a subsoil crusher for crushing subsoil and supplying soil conditioner and fertilizer for the subsoil,

The present invention relates to a soil crusher, and more particularly, to a soil crusher capable of simultaneously performing soil refinement and / or liquid fertilizer (liquid fertilizer) in addition to crushed soil.

The cultivated land is generally aged by the frequent running of the agricultural machinery, so that the soil is hardened and the hardened hard layer is formed between 20 ~ 40cm depth. The increase in the use of large agricultural machinery and the feed of livestock straw are increasing the severity of cirrus stratification. The weathering layer is very poor in air permeability and drainage due to the very small amount of soil porosity. If soil water drainage deteriorates, crops can cause droughts and greatly reduce the vitality of roots, resulting in low productivity.

Subsoil fracture is known to be a good way to solve this problem. According to a survey by the Agricultural Promotion Agency, it is known that about 440,000 hectares, which is about half of the rice fields in Korea, need to be shattered. In order to cultivate the crops such as soybeans in these paddy fields, it is necessary to disrupt the deep-sea soil to a depth of about 35 cm prior to cultivation in a cycle of 3 years (nitrogen oxide) and 5 years (sandy soil) To about 40%.

In this way, it is recognized that the subsoil crushing operation that crushes the excavation layer is an indispensable work in agriculture. As one of them, there is a " deep-sea shredder " proposed by Kwon Tae-wun in Korean Patent Publication No. 10-2012-0119287 (published on October 31, 2012). 1 comprises a compression body 10, an over valve 40, a flow control valve 45, an air supply line 50, a crushing member 60, and an anti-safety means 70 . Air is introduced and stored into the compression body 10 through the air supply line 50 connected to the compressor and the over valve 40 to regulate the flow control valve 45 during the subsoil decomposition, The compressed air is discharged into the interior of the light-emitting layer while adjusting the amount of compressed air stored in the interior of the light-emitting layer. The crushing member 60, in combination with the flow control valve 45, is inserted into the excavation layer for crushing soils to supply compressed air to the soil so that the soil is crushed. This ground shredder is characterized by the use of compressed air to crush the soil.

Other prior art techniques for soil disruption include the following soil shredding apparatus: Korean Patent Registration No. 10-1161535 (Registered on June 25, 2012, Green Solution Co., Ltd., 2 persons, name of invention: Pollution Korean Patent Laid-Open Publication No. 10-2009-0104464 (published Oct. 06, 2009, Cornell D. Flebeni et al., Entitled Compression Fracture and Multicomponent Liquid or Solid Media (Method and Apparatus for Improving Efficiency of Soil and Groundwater Pollution by Underground Pollution).

All of these conventional deep-sea crusher apparatuses have a common point that soil is crushed using compressed air. However, there is a limitation that the crusher devices have only soil crushing function. The crusher devices do not have the ability to perform other operations besides soil crushing, such as fertilizing the soil or applying the soil improvement agent to improve the soil. Therefore, cultivators using the subsoil crusher, apart from the subsoil crushing operation using it, have to work separately with separate equipment to administer the liquid fertilizer and / or soil amendment agent to the soil. Soil modifier is an organic synthetic polymer used in soil for the purpose of improving the physical properties by soil or grafting various materials used in soil to improve physically, chemically and biologically unhealthy soil. Soil modifiers are available in liquid and solid (powder) form.

The present invention enables simultaneous discharge of compressed air and injection of liquid fertilizer and / or soil conditioner using compressed air produced by using one air compressor. It enables the crushing of the subsoil and the subsoil application of the liquid fertilizer and / or the soil improvement agent to be carried out at once, thus greatly enhancing the efficiency of the associated work. It also maximizes the input of fertilizer and soil amendment into the soil. Furthermore, it can reduce the cost of purchasing equipment for farmers because it allows two or three operations to be performed simultaneously by a single air compressor.

The ground shredding apparatus of the present invention uses a rotating force of a drill of a penetrating and crushing rod portion driven by a motor and a hydraulic or pneumatic cylinder pressing force together. Since the penetrating crushing rod is rotated and pressed, the penetrating crushing rod can be penetrated deeper than the conventional crushing machine. In addition, since the penetration force is generated by using a motor and a hydraulic or pneumatic cylinder, the operator does not need to apply a large force. The penetrable depth can be adjusted to the desired level. It can penetrate to a depth of 40 cm or more, preferably to a depth of 70 to 80 cm, and can be crushed. This ability to penetrate deep clay can also be used to practice crossing where it is not possible to have a crossbow (work to feed a pipe under a tree).

FIG. 2 shows the construction of the ground shredder 100 according to the embodiment of the present invention. 3 shows a state in which the penetrating crushing rods 140 of the bottom soil crusher 100 are retracted as much as possible (i.e., a state before being pinched into the ground). Fig. 4 shows the structure and operating mechanism of the penetration crushing rod 140. Fig. FIG. 5 shows a state in which the penetration crushing rod 140 is moved forward to the maximum extent (that is, deeply digging into the ground as deep as possible). 6 shows the configuration of the entire system for operating the soil shredding apparatus 100. As shown in FIG.

The groundwater crusher 100 includes a housing 110, a compressed air tank 120, a chemical tank 130, an infiltration crushing rod 140, an external rotation means 150, a vertical ascending / descending means 160, 170, a force transmission means 180, and a control means 190. Further, this deep-sea shredder 100 requires several additional external devices for continuous shredding operation. That is, the bottom soil remover system 200 includes an external compressed air storage tank 210 and a chemical solution storage tank 220 for storing compressed air and chemical liquid to be supplied to the bottom soil remover 100, And further includes a compressor 230 for generating compressed air (see FIG. 6). The compressed air storage tank 210 is connected to the compressor 230 and the compressed air tank 120 to be described later by pipes 232 and 233, respectively. The chemical solution storage tank 234 is also connected to the compressor 230 and the chemical solution tank 130 to be described later by pipes 234 and 235, respectively. The compressor 230 can be used as a power source so that the compressor 230 can be connected to the fluid input pipe 172 through the pipe 236. In this case, do. If the power source is a hydraulic pressure, it is necessary to provide another hydraulic pressure providing means.

The housing 110 is a box-like box having an upper surface 112, a lower surface 113 and four side surfaces 114. Four support rods 115 in the box connect the upper surface 112 and the lower surface 113 It supports. In the figure, four sides 114 only show their boundaries with dash-dotted lines so as not to interfere with the representation of other components. Two wheels 117 are attached to the bottom of the side surface of the housing 100, and a handle 118 is attached to the top of the side surface. The height of the housing 100 preferably has a height of the user's waist or chest. The user can work while moving the soil shredding apparatus 100 from the land to be worked by using the handle 118 and the wheel 117. [ Only the control means 190 is installed outside the housing 110 and the rest is installed inside the housing 110 among the above-mentioned ground shredding machine 100 components.

The vertical ascending / descending means 160 is means for converting the energy of the hydraulic pressure or the compressed air pressure into a mechanical reciprocating linear motion. For example, a hydraulic cylinder or a pneumatic cylinder. Hereinafter, the hydraulic cylinder 160 will be used for the sake of convenience. Those skilled in the art will have no difficulty in constructing a system employing the pneumatic cylinder based on the description of the hydraulic cylinder 160 as an example.

The hydraulic cylinder 160 is fixed to the upper surface 112 of the housing by hanging upside down. That is, the base portion of the cylinder body 162 is fixed to the upper surface 112 of the housing 110, and the upper portion of the cylinder body 162 is disposed to face the lower surface 113 of the housing 110. The piston rod 164 is connected to a piston (not shown) in the cylinder body 162 and a part of the piston rod 164 is exposed to the outside of the cylinder body 162, (113). At the base and upper portion of the cylindrical body 162 are fluid passages 166 and 168 through which fluids can enter and exit from the outside.

The hydraulic control means 170 includes a fluid supply pipe connecting the external hydraulic supply device 240 and the cylinder body 162 to form a waste hydraulic circuit. The external hydraulic supply device 240 may be implemented, for example, as a bi-directional hydraulic pump, but this is exemplary and any known power source for the hydraulic cylinder may be used. The fluid supply pipe includes first and second fluid input pipes 172-1 and 172-2 connected to two outlets of the hydraulic pressure supply device 240 and first and second fluid input pipes 172-1 and 172-2, A first fluid conduit 176 connected to the first fluid conduit 166 and a second fluid conduit 177 connected to the second fluid conduit 168 from the second fluid conduit 172-2. Further, the fluid supply conduit includes at least one electrically controlled valve for controlling the opening and closing of the conduit. In the figure, an electrically controlled valve 174 and a valve 175 are respectively installed in the first fluid conduit 176 and the second fluid conduit 177 to ensure reliable opening and closing control of the fluid conduits 176 and 177 Respectively. An example of the electrically controlled valves 174 and 175 is a solenoid valve.

The piston moves linearly in accordance with the magnitude of the hydraulic pressure at the top and bottom of the piston (not shown), and the piston rod 164 connected to the piston also moves up and down in the vertical direction by the stroke of the piston. That is, the length of the piston rod 164 protruding out of the cylinder body 162 is varied by the piston stroke.

A compressed air tank 120 and a chemical tank 130, which are containers for holding compressed air and a chemical liquid (liquid fertilizer and / or soil remediation agent, etc.), respectively, are installed on the upper portion of the housing 110. The two are joined by a coupling member 186 to move like a body. The coupling member 186 is made of a metal plate and is welded to the body of the compressed air tank 120 and the chemical bottle 130. For the welding, the compressed air tank 120 and the chemical bottle 130 are preferably made of a metal material. The coupling member 186 is extrapolated to the four support guide rods 115 via the guide bushing 183b and is able to slide in the vertical direction on the support rods 115.

The force transmitting means 180 connects the compressed air tank 120 and the chemical solution bottle 130 together with the piston rod 164 so as to vertically ascend and descend. The force transmitting means 180 includes, for example, a plate-shaped force transmitting member 182 for horizontally connecting them. The force transmitting member 182 is extrapolated to the piston rod 164. At the same time, the force transmitting member 182 is integrally connected to the compressed air tank 120 and the chemical bottle 130 by welding, for example, and serves as a coupling member of the two containers 120 and 130. This force transmitting member 182 is coupled to the four support guide rods 115 slidable in the vertical direction via the guide bushing 183a as in the case of the engaging member 186. [ The compressed air tank 120 and the chemical solution bottle 130 are doubly joined to each other at the lower portion and the upper portion by the force transmitting member 182 and the engaging member 186,

The force transmitting means 180 also includes first and second force transmission rings 184 and 185 which are fitted at two points of the piston rod 164, that is, a point just below and a point just below the point where the force transmitting member 182 is fitted, . The first and second force transmission rings 184 and 185 are rigidly coupled to each other so as not to slip in a direction perpendicular to the piston rod 164. The force that the piston rod 164 is vertically lowered is the first force transmission ring 184 just above the force transmitting member 182 and the vertical rising force is transmitted to the second force transmission member 182 just below the force transmitting member 182. [ The ring 185 is transmitted to the force transmitting member 182.

With this configuration, the force transmitting means 180 transmits the vertical up-and-down movement of the piston rod 164 to the compressed air tank 120 and the chemical liquid container 130 as it is. Therefore, when the piston rod 164 is vertically lifted and lowered, the compressed air tank 120 and the infiltration crushing rod 140 and the chemical solution bottle 130, which are integrally connected to the compressed air tank 120, become one body with the piston rod 164 And is forced to perform vertical up and down movement.

FIG. 4 shows the structure of the penetrating crushing rod 140 and the coupling relation with surrounding components. The penetrating crushing rod 140 has a double pipe structure composed of an inner pipe 142 and an outer pipe 144 containing the inner pipe 142. The penetrating crushing rods 140 are preferably made of a high-strength metal material.

The inner pipe 142 is connected in communication with the compressed air tank 120 and the chemical bottle 130, respectively, and is provided as a discharge path for the compressed air and the chemical liquid. The upper end of the inner pipe 142 is integrally joined to the lower end of the compressed air tank 120 by, for example, a welding method or a screw coupling method. The inner pipe 142 is integrated with the compressed air tank 120 and is vertically lifted and lowered by the vertical lifting force of the vertical lifting means 160 transmitted by the compressed air tank 120 can do. The inner tube 142 also extends vertically downwardly in parallel with the support guide rods 115 so that the distal end thereof protrudes out of the housing bottom surface 113.

An electrically controlled valve 122 such as a solenoid valve is installed near the upper end of the inner pipe 142, that is, the lower end outlet of the compressed air tank 120. The valve 122 is for controlling the compressed air in the compressed air tank 120 to be blown into the inner pipe 142. An electrically controlled valve 124 is also provided near the top inlet of the compressed air tank 120. The valve 124 is for controlling the introduction of compressed air in the compressed air storage tank 210 into the compressed air tank 120.

The inner tube 142 also communicates with the lower portion of the chemical solution bottle 130 through the chemical solution tube 132. An electrically controlled valve 134 may also be provided in the lower end outlet of the chemical solution container 130 or in the chemical solution pipe 132. This valve 134 is for controlling the chemical solution in the chemical solution bottle 130 to be injected into the inner pipe 142. It is preferable that the chemical liquid tube 132 is connected to the inner tube 142 at a position lower than the valve 122. An electrically controlled valve (not shown) may also be provided at the upper inlet of the chemical solution container 130 connected to the chemical solution storage tank 220.

The outer surface 144 is configured to pierce the ground as it rotates. To this end, the outer tube 144 is rotatably mounted, while containing the inner tube 142 which is not rotatable. The outer tube 144 extends downward while containing the inner tube 142 at a position lower than the connection point between the valve 122 and the chemical liquid tube 132, and a drill 148 is mounted at the distal end thereof.

At the upper end of the outer tube 144, an outer rotation means 150 for rotating the outer tube 144 is provided. The external rotating means 150 includes a motor 152 driven by an electric motor and two bevel gears 153 and 154 and a motor support member 170 integrally connecting the motor 152 to the force transmitting member 182 156). The outer tube 144 is rotated by the rotational force of the motor 152. The first bevel gear 154 is coupled to the rotating shaft of the motor 152. At the upper end of the outer tube 144, the second bevel gear 153 is integrally coupled using, for example, a bolt. The first bevel gear 154 and the second bevel gear 153 mesh with each other. The rotational force of the motor 152 is transmitted to the outer tube 144 via the two bevel gears 153 and 154. The motor 152 is fixed to and supported by the motor support member 156. The motor support member 156 is coupled to the force transmitting member 182 to make a vertical movement integrally therewith. Therefore, the outer appearance rotating means 150 also performs vertical up-and-down movement in synchronism with the vertical movement of the piston rod 164. The motor 152 and the first bevel gear 154 are also vertically lowered while the piston rod 164 is vertically lowered so that the first bevel gear 154 is in contact with the outer cylinder 144 ) Vertically downward. As a result, while the vertical descent of the piston rod 164 and the rotation of the motor 152 occur at the same time, the outer tube 144 rotates and moves vertically downward. The infiltration crushing rod 140 digs the ground while performing this exercise.

On the contrary, means for transferring the force generated during the vertical rise of the vertically lowered piston rod 164 to the lowest point of the stroke to the external appearance 144 to further elevate the external appearance 144 vertically is provided. This means includes a gear support member 188, a guide bushing 183, and a bearing 189. Preferably, the gear receiving member 188 is extensively extruded through the guide bushing 183c into the four support guide rods 115, and is made of a metal plate having high strength. The gear receiving member 188 is also extruded to the outer surface 144. A ring-shaped bearing 189 is disposed directly below the second bevel gear 153 to rotatably support the second bevel gear 153. The bearing 189 is fixed to the gear receiving member 188. The gear support member 188 is integrally connected to the motor support member 156. Therefore, the gear receiving member 188 becomes integral with the motor supporting member 156 and the force transmitting member 182, and makes a vertical ascending / descending motion such as the piston rod 164 through them. While the piston rod 164 is vertically lifted, the gear support member 188 moves in the same manner. The bearing 189 pushes up the second bevel gear 153 vertically upward so that the outer tube 144 can be raised by the distance that the piston rod 164 has risen. It is preferable to additionally attach a member directly connecting the gear receiving member 188 and the force transmitting member 182 to the opposite side of the motor supporting member 156 to more firmly connect the two members. Of course, since the gear support member 188 is required to be capable of receiving the normal vertical descent force of the piston rod 164, it is possible to transmit the vertical load-lifting force of the piston rod 164 to the members other than the motor support member 156 or the motor support member 156, Or may be coupled to at least one of the pressure chamber 164, the compressed air tank 120, the chemical container 130, and the force transmitting member 182.

A plurality of openings 146 are provided at corresponding points of the distal end of the inner tube 142 and the outer tube 144, respectively, through which compressed air and chemical liquid can be sprayed 360 degrees omnidirectionally. The drill 148 is located directly below these openings 146. For example, it is preferable that at least four openings 146 are provided to the north, south, south, south, and south so that the compressed air and the chemical liquid are ejected through the openings into the soil in the radial direction toward the south, north, south,

The control means 190 controls the drive of the vertical up / down means 160, the drive of the motor 152 for the outer rotation means 150, the supply and discharge control of the compressed air to / from the compressed air tank 120, And control of the supply and discharge of the chemical liquid to / from the chemical solution container 130. The control means 190 includes a control box 192 fixed to a side wall of the housing 110, a control circuit (not shown) incorporated therein, and a plurality of control switches 194 which can issue a user command to the control circuit. .

The provided control switch 194 includes an air injection switch S1 for directing compressed air injection into the compressed air tank 120, a chemical liquid supply switch S2 for instructing chemical liquid supply into the chemical liquid tank 130, The infiltration switch S3 for directing the rod 140 to vertically descend into the soil and the soil to be crushed by ejecting the compressed air and the chemical solution through the opening of the infiltration crushing rod 140 penetrating into the soil And a retraction switch S5 for instructing to retract the infiltration crushing rods 140 after the soil rupture back to the original position (retreat position), that is, to vertically rise.

The control circuit receives a signal according to a user operation from each control switch and controls the related components so that an operation corresponding to the input signal can be performed. To this end, the control circuit includes hardware such as an operation control device (CPU), a memory, control switches 194 and a wiring circuit for electrically connecting the control target elements to the operation control device. In addition, programs to be performed for each input signal provided by the control switch 194 are prepared and stored in a memory. The operation control device executes the control program and controls the control objects with the control signal generated. The specific control contents of the control means 190 will be described in the course of describing the overall operation of the bottom soil shredding system 200 described below.

(1) preparation step

This step is a step in which the user moves the soil shredding apparatus 100 to a desired point or moves it and then performs preparation work for the soil shattering. 3, the piston rod 164 is retracted to the top (this state is the state where the piston in the cylinder body 162 is at the bottom dead center), so that the penetration crushing rod 140 is in the retracted position . For preparatory work, the user presses the air injection switch S1. When the switching signal is generated in the air injection switch S1, the control circuit controls the compressed air tank 120 to be filled with the compressed air so that the chemical solution tank 130 is filled with the chemical solution at least once more than the injection amount. That is, the upper valve 124 and the lower valve 122 of the compressed air tank 120 are closed. When the air injection switch S1 is operated, the upper valve 124 is opened, A part of the compressed air stored in the compressed air tank 210 flows into the compressed air tank 120 and is stored. The chemical solution storage tank 220 maintains the state of being pressurized by the compressor 230, so that the chemical solution is always kept filled with the chemical solution. However, an electronically controlled valve (not shown) may be additionally provided in the chemical liquid channel 233 to more reliably control the supply of the chemical liquid to the chemical liquid container 130. In this case, it is possible to control the chemical solution supply to the chemical solution container 130 by operating the chemical solution operation switch S2.

(2) Penetration step

This step is performed after the preparation work is completed. This step is a step of putting the penetration crushing rod 140 into the ground to a desired depth. To this end, the user sets up the housing 110 vertically with respect to the ground, and then manipulates the infiltration switch S3. The control circuit of the control means 190 receives the signal of the infiltration switch S3 and performs the following control.

First, the control circuit (i) functions as a hydraulic pressure supply device 240 to move the piston at the bottom dead center in the cylinder body 162 to the top dead center and push the piston rod 164 out of the cylinder body 162 for a long time (Ii) the opening of all the valves 174, 175 in the hydraulic circuits 172-1, 176, 162, 177, 172-2. The fluid in the hydraulic circuit is pressurized by the hydraulic pressure supply device 240 and is supplied to the cylinder body through the first fluid passage 166 via the first fluid inlet pipe 172-1 and the first fluid passage 176 162), pushing the piston toward the top dead center. The fluid on the top dead center side of the piston is pushed out of the cylinder body 162 through the second fluid passage 168 and flows through the second fluid passage 177 and the second fluid input pipe 172-1, (240).

When the piston moves from the bottom dead center to the top dead center due to the oil pressure, the piston rod 164 extends vertically downward by the distance (stroke) the piston travels, and thereby the piston rod 164 is directly or indirectly moved Other components that are coupled together are forced to move vertically downward as much as the stroke of the piston. The compressed air tank 120 and the chemical solution bottle 130 integrally connected to the piston rod 164 via the force transmitting member 182 and the penetration crushing rod 140 directly connected to the compressed air tank 120, The inner tube 142 of the piston rod 164 also moves vertically downward by the stroke distance of the piston rod 164. At this time, since the coupling member 186, the motor support member 156, the gear support member 188, and the components fixed to them are directly or indirectly integrally connected to the force transmitting member 182, As shown in FIG. As a result, the inner tube 142 of the penetration crushing rod 140 is pushed into the ground as much as the stroke of the piston by the pressing force of the compressed air tank 120.

However, the pushing force of the penetrating crushing rod 140 vertically downwardly is not easy to penetrate deeply into the light-emitting layer and is time-consuming and inefficient. It is preferable that the penetrating crushing rod 140 is pierced while rotating. To this end, the control circuit controls the motor 152 of the external rotation means 150 to operate in synchronization with the operation of the hydraulic supply device 240.

The rotational force of the motor 152 rotates the outer surface 144 of the penetrating crushing rod 140 through the first and second bevel gears 154 and 153 while the motor 152 is operating. As a result, the drill 148 at the tip of the outer tube 144 rotates and digs the ground. In this process, the vertical downward force of the piston rod 164 provided by the piston is transmitted through the force transmitting means 180, the motor support member 156, the motor 152, the first and second bevel gears 154 and 153, So that the outer tube 144 receives a force to vertically downwardly move. As a result, the vertical force and the rotational force are simultaneously applied to the outer tube 144, and the outer tube 144 is rotated into the ground while rotating. Since the vertical downward forces acting on the outer tube 144 and the inner tube 142 are the same force, they enter the ground at substantially the same speed. This method allows the penetrating crushing rods 140 to penetrate the ground much more effectively and quickly, compared to penetrating only with the vertical downward force.

After a sufficient time has elapsed to allow the piston to reach the top dead center due to the flow of fluid, the control circuit closes the valves 174, 175 to maintain the state of the fluid flow, And the motor 152 are stopped. In this state, as shown in FIG. 4, the penetrating crushing rod 140 extends out of the housing bottom surface 113 for as long as possible.

(3) Shredding step

In the state in which the penetrating crushing rod 140 penetrates into the subterranean shear layer through the above process, the user presses the crushing switch S4 and instructs the soil crushing. The control circuit of the control means 190 controls the compressed air in the compressed air tank 120 and at least a part of the chemical solution in the chemical solution tank 130 to flow into the inner pipe 142 through the opening 146 (see Fig. 6). To this end, the control circuit controls the valve 122 under the compressed air tank 120 and the valve 134 under the chemical solution bottle 130 to be opened. The two valves 122, 134 may be opened at the same time, or the valve 122 may be opened after a predetermined time after opening the valve 134 first. According to the former method, the chemical solution and the compressed air will be mixed in the inner tube 142 and ejected into the opening 146. According to the latter method, the inner tube 142 is first filled with the chemical solution, and then the compressed air pushes the chemical solution Will be ejected.

Since the air in the compressed air tank 120 is compressed at a high pressure, it is sprayed at a very high speed through the opening 146 in all directions of 360 degrees. As if the explosion occurred in the ground, the ground is slightly shaken up and falls down, and it is crushed very finely to the light layer. In the process, the chemical solution mixes evenly between shredded soils. Crushing layer crushing and injection of chemical liquid (liquid fertilizer and / or soil amendment agent) are performed at the same time. The soil is crushed in an area of approximately 1.5 to 2.5 m radius per crush. The housing (113) clogs the clay that splashes up when crushed. If you make the bottom surface 113 wider, you will be able to prevent it more clearly.

(4)

When the shredding step is finished, the user presses the retraction switch S5. The control circuit controls the piston to return from the top dead center to the bottom dead center when the signal of the backward switch (S5) is inputted. That is, the control circuit causes (i) the bi-directional pump functioning as the hydraulic supply device 240 to rotate in the opposite direction to that in the infiltration step, (ii) the hydraulic circuit 172-1, 176, 162, 177, 172 -2). ≪ / RTI > Then, the fluid in the hydraulic circuit moves in a direction opposite to that in the infiltration step to move the piston toward the bottom dead center. Thereby, the piston rod 164 and the components directly or indirectly integrated therewith are moved vertically and upwardly in the mode. Therefore, the inner tube 142 of the penetrating crushing rod 140 is also pulled up by the stroke of the piston.

The gear support member 188 and the bearing 189 are coupled to the piston rod 164 via the force transmission means 180 and the motor support member 156 so that they are synchronized when the piston rod 164 is moved vertically upward And vertically upward. The outer bead 144 of the impregnation crushing rod 140 is also attached to the piston rod 164 and the inner pipe 142. As a result, the second bevel gear 153 is caught by the vertically rising bearing 189, And the piston stroke.

Through the above process, the bottom soil crusher 100 is returned to its original position. In this process, the motor 152 may be driven so that the outer tube 144 may be rotated and raised. In most cases, since the surrounding soil is in a crushed condition, the outer surface 144 will be able to escape even if it is pulled straight without rotating.

The user moves through several points of the soil to be shredded, and performs four steps of preparatory step, penetration step, crushing step, and return step described for each point. As described above, the deep-sea crusher 100 of the present invention presses the penetration crushing rod 140 at a desired point of the sheath layer with mechanical force to effectively penetrate the hard sheer layer, and then pressurizes the high- At the same time, the crushed layer is crushed and the chemical liquid can be supplied evenly to the crushed soil.

On the other hand, the inner tube 142 of the penetrating crushing rod 140 is formed of another member (for example, the liquid medicine cylinder 130, the piston rod 164, the force transmitting member 142, (182), etc.) to be able to receive the vertical lift force directly from the member. In this case as well, the inner tube 142 should be connected to the compressed air tank 120 and the chemical tank 130 so as to maintain the same.

It may be directly under the liquid medicine cylinder 130 or directly to the force transmitting member 182. [ When the inner tube 142 is coupled to the chemical solution container 130, it is preferable that the chemical solution container 130 and the compressed air tank 120 are mutually interchanged in position.

In addition, the hydraulic cylinder is only an example of the vertical ascending / descending means 160. Instead of the hydraulic cylinder, other means having substantially the same function may be used to implement the vertical lifting means. That is, while being supported by the housing 110, the control unit 110 provides sufficient force necessary to infiltrate the infiltration crushing rod 140 into the ground or retract it from the ground, It can be used as the vertical ascending / descending means 160. Such a mechanism may be constituted by, for example, a motor, gears, and a rod member corresponding to the piston rod 164 or the like.

The inner pipe 142 is connected to the vertical up-down means 160, the compressed air tank 120, the chemical liquid tank 130 (see FIG. 1), the inner pipe 142 of the infiltration crushing rod 140 is directly coupled to the compressed air tank 120, ), A force transmitting member 182 serving as a joining member, and / or a joining member 186 may be provided so as to be provided with a vertical lifting force generated by the vertical lifting means 160. In this case, too, the compressed air tank 120 and the chemical solution container 130 are connected to communicate with each other, and the connection with the external appearance 144 should be substantially the same as that described above.

Accordingly, the true scope of protection of the present invention should be determined by the appended claims and technical matters.
