Description

  The present invention relates to a self-propelled jaw crusher that crushes objects to be crushed such as rocks.

  A jaw crusher is a type in which a material to be crushed, such as rock, is put into a V-shaped crushing chamber between a fixed tooth and a moving tooth, which are installed opposite to each other, and the object to be crushed is crushed by the swinging motion of the moving tooth with respect to the fixed tooth Crushing device. Usually, the material to be crushed is fed by a loading heavy machine such as a hydraulic excavator. However, if the material to be crushed is thrown directly and intermittently into the jaw crusher by the loading heavy machine, the fluctuation of the crushing load is large. In many cases, a feeder for supplying a material to be crushed is provided, and the material to be crushed is continuously supplied to the jaw crusher by a set amount by feeding the material to be crushed into the feeder. At this time, the feeder is generally provided with a hopper that expands upward in order to smoothly guide the material to be crushed input by the input heavy machine to the feeder (see Patent Document 1, etc.).

JP 2010-82603 A

  Here, in the self-propelled jaw crusher capable of traveling on its own, the size of the airframe is restricted to the transport limit size because it is loaded on a transportation vehicle such as a trailer without being disassembled as much as possible and transported on a general road. In addition, the conveyor for carrying out the object to be crushed needs to be arranged with a predetermined clearance from the ground in consideration of various circumstances related to traveling, and the jaw crusher only deposits the object to be crushed on the conveyor. It is installed upwards after securing the gap. The feeder is in a higher position than the jaw crusher in terms of supplying the material to be crushed to the jaw crusher, and it is difficult in terms of design to ensure a sufficient dimension from the upper part of the feeder to the transport limit height. Since the hopper must be designed to be within this limited height dimension (the dimension from the upper part of the feeder to the restricted transport height), it is difficult to ensure a sufficient depth. In addition, since the dimension in the body width direction is also restricted by the transport limit width, the inclination angle of the wall surface constituting the hopper is also limited.

  On the other hand, as the area where the jaw crusher plays an active role has expanded, in recent years, an increasing number of sites using a heavy loader such as a wheel loader as an input heavy machine for inputting an object to be crushed. This type of input heavy machine has a large input amount per time due to the capacity of the bucket, and there is a possibility that the crushed object cannot be sufficiently received by the hopper whose depth is restricted as described above. For example, when throwing objects to be crushed such as fluid earth and sand into the hopper from the right side of the fuselage, the objects to be crushed once put into the hopper will gain momentum. There is a risk of spilling over the wall on the left side.

  This invention is made | formed in view of said situation, and it aims at providing the self-propelled jaw crusher which can improve the acceptability of the to-be-crushed object by a hopper irrespective of the property of a to-be-crushed object.

  In order to achieve the above object, the first invention is provided on a traveling body, a jaw crusher provided on the traveling body, a feeder for supplying an object to be crushed to the jaw crusher, and an upper part of the feeder. A hopper, and the hopper includes left and right side walls inclined upward in the body width direction upward, a rear side wall closing an internal space at a rear end portion of the left and right side walls, and the left and right sides. It is provided with the upper part of one side wall of this side, and it is provided with the side part angling board which inclines in the body width direction toward the upper direction, It is characterized by the above-mentioned.

  According to a second aspect of the present invention, in the first aspect, an attachment portion provided at a lower portion of the side rim plate protrudes inward in the body width direction, and the attachment portion is fastened and fixed to the side wall. It is characterized by being.

  According to a third invention, in the first or second invention, the side groin plate is formed in a rectangular shape and can be selectively attached to any one of the left and right side walls. And

  A fourth invention is characterized in that, in the third invention, a rear edge plate is provided at an upper end of the rear side wall and extends upward along a vertical plane.

  According to a fifth aspect, in the fourth aspect, the rear edge plate is formed in a trapezoidal shape in accordance with an inclination angle of the side wall.

The pin 41 passes through the lower pin support portion 42a, and the pin 41 is welded to the pin support portion 42a. The upper bolt fastening portion 42b is provided with bolt holes 49a-49d in which female threads are cut in an arrangement of two rows and two columns. The arrangement of the pins 41 and the bolt holes 49a to 49d and the shape of the bracket 42 are symmetrical in the front-rear direction (left-right symmetry in FIG. 12) when viewed from the left-right direction of the machine body.

  FIG. 14 and FIG. 15 are configuration diagrams showing the block 43 extracted, FIG. 14 is a side view seen from the outside in the width direction of the aircraft when attached to the aircraft, and FIG. 15 is a front view seen from the front of the aircraft. Equivalent to.

  14 and 15, the block 43 is welded above the mounting portion 43b in the base 43a, the mounting portion 43b welded to the surface of the base 43a facing the bracket 42, and the base 43a. A back nut 43c is provided. Although the shape of the main surface (widest surface) of the base 43a is not particularly limited, in the present embodiment, it is formed in a quadrangular shape with Rs at the four corners (rounded four corners). The attachment portion 43b is a rectangular flat plate having a smaller area than the base 43a, is a portion facing the bolt fastening portion 42b of the bracket 42, and is attached to the lower side of the base 43a. The mounting portion 43b is provided with through holes 50a-50d arranged in 2 rows and 2 columns. The through holes 50a-50d penetrate the base 43a. On the other hand, the back nut 43c is provided in the upper part of the attaching part 43b by 1 row | line | column 2 arrangement | positioning. Through holes 5e and 50f having a slightly larger diameter than the female screw 43ca of the back nut 43c are provided at positions corresponding to the back nut 43c in the base 43a. The shape and arrangement of the through holes 50a-50f, the base 43a, the attachment portion 43b, and the back nut 43c are symmetric in the front-rear direction (left-right symmetry in FIG. 14) when viewed from the left-right direction of the machine body.

2. Assembly Procedure In the present embodiment, when the discharge conveyor 13 is assembled to the traveling body 1, the discharge conveyor 13 is first assembled in advance before the assembly. At this time, the conveyor frames 22a and 22b of the upstream conveyor 13a and the downstream conveyor 13b are connected to each other by pins 41 inserted into the brackets 22aa and 22ba from the outside in the horizontal direction. It is not necessary to prevent the split pins and the like from coming off, and the pins 41 and the bracket 42 are temporarily assembled.

  Before and after this, on the traveling body 1 side, the block 43 is aligned with the inner surface of the mounting portion 44 of the track frame 5 in the left-right direction of the airframe, and the bolt 46 is inserted from the outer side of the left-right direction of the airframe. 46 is screwed to the back nut 43 c of the block 43 to attach the block 43 to the track frame 5. At this time, the jaw crusher 12, the grizzly feeder 11, the hopper 10, the power unit 14, or the like is not necessarily assembled to the traveling body 1. However, when the discharge conveyor 13 is assembled, the traveling body 1 is self-propelled. Since the workability may be improved if the positional relationship with 13 can be adjusted, it is preferable to mount the power unit 14 in that case.

  Subsequently, the discharge conveyor 13 is placed between the left and right traveling devices 3 of the traveling body 1 (or the traveling body 1 is moved onto the discharge conveyor 13), and the discharge conveyor 13 is lifted by a lifting means such as a crane or a chain block. Then, the discharge conveyor 13 is held in a suspended posture, the support member 35 is connected to the upstream conveyor 13 a and suspended from the main body frame 4, and the downstream conveyor 13 b is connected to the front end portion 4 a of the main body frame 4. Then, before and after this, the brackets 42 temporarily attached to the upstream conveyor 13a and the downstream conveyor 13b by the pins 41 are overlapped on the inside of the block 43 attached to the track frame 5, and the left and right direction of the machine body The bolts 45 are inserted from the outside and the bolts 45 are screwed into the bolt holes 49 a to 49 d of the bracket 42, thereby connecting the bracket 42 to the inner wall surface of the track frame 5 in the left-right direction. When this connection is completed, the pin 41 is fixed to the track frame 5 while holding the conveyor frame 22 from the outside, and is restrained by the track frame 5, so that the pin 41 moves to the left and right with respect to the conveyor frame 22. This prevents the conveyor frame 22 from falling off the pins 41.

  Thereafter, if the jaw crusher 12, the grizzly feeder 11, the hopper 10, the power unit 14, or the like is not yet assembled, the assembly of the self-propelled crusher 100 is completed by assembling them sequentially to the traveling body 1.

  In the present embodiment, the upstream conveyor 13a and the downstream conveyor 13b of the discharge conveyor 13 are connected by pins 41, and the upstream conveyor 13a is bent with respect to the downstream conveyor 13b. By connecting the upstream end of the upstream conveyor 13a to the main body frame 4 via a cylinder (not shown) instead of 35, the upstream conveyor 13a can be swung up and down with the pin 41 as a fulcrum. it can. When configured in this way, it is desirable not to hold the upstream conveyor 13a only by the cylinder but to arrange support members that can selectively hold the upstream conveyor 13a according to the angle.

3. Operation Next, the operation of the self-propelled crusher 100 configured as described above will be described.

  For the self-propelled crusher 100 during the crushing operation, an object to be crushed is put into the hopper 10 by a loading heavy machine such as a wheel loader. At this time, in the configuration of FIGS. 1 to 7, the object to be crushed is thrown into the hopper main body 27 from the right side of the machine body without the turning member 28. The charged material to be crushed is guided onto the grizzly feeder 11 and conveyed toward the jaw crusher 12. At that time, fine particles (slipping etc.) smaller than the gaps between the comb teeth 18 of the grizzly plate 19 are guided to the discharge conveyor 13 through the gaps through the chute 21 and larger objects (large blocks) ) Is supplied to the jaw crusher 12. The object to be crushed supplied to the jaw crusher 12 is crushed to a particle size corresponding to the exit gap of the crushing chamber between the fixed teeth and the moving teeth and falls onto the discharge conveyor 13 below. The crushed material crushed by the jaw crusher 12 joins the fine particles selected by the grizzly feeder 11 and is conveyed forward by the discharge conveyor 13, and foreign substances such as reinforcing bars are adsorbed and removed by the magnetic separator 24 on the way. It is carried out of the machine above.

4). Effects According to the present embodiment, the following effects can be obtained.

(1) Improving the acceptability of the object to be crushed The self-propelled jaw crusher 100 according to the present embodiment has the turning member 28 erected on the edge of the upper opening of the hopper body 27 during operation. The turning member 28 is open on one side in the left-right direction (on the right side in the example of FIGS. 1 to 7), and the opened side portion is the input position of the object to be crushed. When the material to be crushed is introduced from this position, even when a highly fluid material to be crushed containing a large amount of fine particles and the like is introduced using a loading heavy machine having a large capacity bucket such as a wheel loader, the hopper main body 27 Since the side edge plate 31S is inclined and erected on the inner side of the hopper 10 on the opposite side (left side in the example of FIGS. 1 to 7), the cover is about to cross the side wall on the opposite side. The crushed material can be dammed up by the side side plate 31S, and spillage from the hopper 10 can be suppressed. Of course, since the rear groin plate 31R and the front groin plates 31FL and 31FR are also erected on the rear and front portions of the hopper main body 27, spills from the rear and front can be suppressed. Accordingly, the depth of the hopper main body 27 and the inclination angles of the side walls 29L, 29R and the like are restricted by transportation restrictions on general roads, but the hopper 10 can be attached regardless of the properties of the object to be crushed by attaching the turning member 28 during operation. The acceptability of the object to be crushed can be improved.

  At this time, if the rear cover plate 31R and the front cover plates 31FL, 31FR are inclined to the inside of the hopper 10 (forward in the case of the rear cover plate 31R, rearward in the case of the front cover plates 31FL, 31FR), the aircraft side However, in this embodiment, the rear entrance plate 31R and the front end plates 31FL and 31FR are vertically set to reduce the introduction entrance. Avoiding a drop in input performance.

(2) Consideration of detachability of the twisting member Since the attachment portions 31Fa and 31Fb protrude to the outer wall side with respect to the front facing plates 31FL and 31FR, it is necessary to access the attachment portions 31Fa and 31Fb from the outside of the hopper 10 However, if the floor around the jaw crusher 12 is used as a scaffold, the attachment portions 31Fa and 31Fb can be easily accessed. However, there is no scaffolding on the outside with respect to the side edge plate 31S and the rear edge plate 31R, and when these attachment portions are provided on the outer wall side, a tall stepladder is used or a separate scaffold is assembled. Workability is poor.

  On the other hand, the attachment portions 31Sa and 31Rb of the side edge plate 31S and the rear edge plate 31R with respect to the hopper main body portion 27 protrude inside the hopper 10, so that the attachment portion can be obtained by using the grind plate 19 in the hopper 10 as a scaffold. 31Sa and 31Rb can be easily accessed, and the attachment portions 31Sa and 31Rb can be easily attached to and detached from the hopper body portion 27.

(3) System flexibility Depending on the site, sufficient space cannot be secured around the self-propelled jaw crusher 100, and a system layout in which the material to be crushed must be put in from the left or right side of the hopper 10 is unavoidable. Can also occur. In such a case, in the present embodiment, the side edge plate 31S is formed in a rectangular shape that is symmetrical in the front-rear direction, and is configured so that it can be selectively attached to either the left or right of the hopper 10 by reversing back and forth. The input position can be freely changed to either the left or right according to the situation.

(4) Consideration for the operator of the input heavy machine For example, when the self-propelled jaw crusher 100 is operated in the space between the structures at the demolition site of the structure, there is a case where a sufficient space cannot be secured on the side of the jaw crusher 100. . In such a case, when the rear heavy plate 31R is formed in a rectangular shape when moving the input heavy machine scooping up the crushed objects at a predetermined accumulation location or the bucket thereof to the side of the hopper 10, When the throwing heavy machine or the bucket is wound around the side portion of the self-propelled jaw crusher 100, the path is narrow and the corners of the rear grind plate 31R are cut so that the bucket or the like does not hit the rear grind plate 31R. To force heavy machinery operators to be more careful than necessary. This is particularly noticeable when a wheel loader having a wide bucket in the left-right direction is used as a loading heavy machine.

  On the other hand, in the present embodiment, the left and right sides of the rear cover plate 31R are inclined according to the inclination angle of the side wall 31S, and formed into a trapezoidal shape in a rear view to reduce the feeling of pressure. Therefore, the operator of the input heavy machine moving to the side portion of the hopper 10 from the collection place of the object to be crushed behind is not forced to be more careful than necessary, and the good input property of the object to be crushed is ensured. Can do.

5. Others In the above-described embodiment, the discharge conveyor 13 is illustrated in which the upstream conveyor 13a can be bent with the pin 41 as a fulcrum with respect to the downstream conveyor 13b. However, the discharge conveyor 13 does not necessarily have a bent structure. Is also applicable to a fixed frame type discharge conveyor that does not bend. This is because even if the frame is fixed, the pin 41 can be inserted from the side and connected to the track frame 5 via the bracket 42 or the like.

  In addition, the mounting portion 44 protrudes forward from the post portion 48 of the track frame 5 so that the bolts 45 and 46 can be easily operated from the side of the machine body, but the conveyor frame 22 is connected to the track frame 5 via the pins 41. For connection, the attachment portion 44 does not necessarily protrude forward, and for example, the bracket 42 and the like can be directly connected to the wall surface in the body width direction of the post portion 48 of the track frame 5.

  Moreover, although the case where this invention was applied to the self-propelled crusher 100 which provided the discharge conveyor 13 on the opposite side to the hopper 10 (accepting object to be crushed) has been described as an example, it is discharged to the same side as the hopper. The present invention can also be applied to a self-propelled crusher having a configuration provided with a conveyor. Further, although the case where the present invention is applied to the crawler type self-propelled crusher 100 having the crawler belt 8 of the endless track as the traveling means has been described as an example, the wheel-type self-propelled jaw having the tire as the traveling means is described. The present invention can also be applied to a crusher. In these cases, similar effects can be obtained.
