This technical solution relates to devices for marking the route and can be used in various seeders, agricultural units and complexes.

State of the art

An analogue of this technical solution is a marker device for agricultural machinery (hereinafter referred to as the device) used in the Kverneland DG trailed seeder - working width 9.12 (m) (supplier of Kverneland Group CIS LLC, 123557, Moscow, Middle Tikshinsky Lane, d. 28, p. 1; plus 7 (495) 6 632 475). The disadvantage of this device is the increased consumption of energy due to the increased weight, as well as the large friction forces that occur when it comes into contact with the soil.

The next analogue is the device used in the MEGA - METROMEGA mechanical seeder (MASCHIO GASPARDO) - working width 12 m. Official dealer: POVOLZHETEHSERVICE LLC, Penza, ul. Austrina, 63, t. (8412) 30-68-56. The disadvantage of this device is similar to the previous model.

Other analogs of the devices used in the seeder for sowing seeds of agricultural crops, described in paragraph 3 of the patent formula for the invention No. 2004123354 of July 30, 2004, and the sowing combination unit in the patent for invention No. 2411708 of October 29, 2007, have the same disadvantages as all of the above analogues.

Another analogue is the device used in the seeders “Citan” and “Citan 12001 - С” - the working width is 8, 9, 12, 15 (m). Production of CJSC Eurotehnika, 443044, Samara, ul. Trunk, VOG, tel. plus 7 (846) 9314093, the disadvantage of which is the same as the previous model.

The closest analogue (prototype) of the claimed technical solution is a "marker device for agricultural machinery", utility model patent No. 138458, priority dated October 14, 2013 (hereinafter referred to as the prototype).

The disadvantage of the prototype:

- insufficient pressure of the air stream at the outlet of the device does not allow the use of this device in wide-seeders (8, 9, 12, 15 (m)), as well as in seeders with a working width of 6 m or less (with large compressor wear), which does not reduce energy costs.

Utility Model Disclosure

The purpose of creating the proposed technical solutions is to reduce energy costs (hereinafter referred to as energy costs).

In addition, the proposed technical solutions will allow: to reduce the weight of devices, and therefore the weight of seeders, aggregates, complexes, including by eliminating the hydraulic cylinders for lifting (lowering) the devices and metal (metal-rubber) pipelines connecting the hydraulic cylinders to the general hydraulic system of the unit (seeder complex); increase the tractor pulling force due to the lack of mechanical contact of the devices with the soil and the reduction of their weight and the weight of seeders, aggregates, complexes; reduce the time for maintenance and repair, since it will not be necessary to periodically lubricate bearings and other parts, as well as change them, eliminate leaks in the hydraulic system, including hydraulic cylinders for lifting devices; to increase the reliability of devices, and therefore seed drills, complexes, aggregates; exclude lubricant (included in the lubrication of devices); reduce the amount of hydraulic fluid used in the hydraulic system; create convenience in management; increase the capacity of the hopper or the width of the seeders, complexes, aggregates; to increase the productivity of sowing complexes, aggregates, seeders due to the lack of lifting (lowering) of devices; reduce energy resources by eliminating device breakdowns caused by stresses when the disks come into contact with the soil (since restoring broken individual parts and assemblies requires additional energy resources); increase the pressure of the air leaving the device by an order of magnitude and higher; receive a trace from the device with a worn tractor compressor; get additional savings through the use of the optimal pressure setting mode; adjust the air pressure with the pressure regulator of the pressure amplifier; reduce additional energy costs by eliminating tractor driver errors when working with switches.

Using the optimal pressure setting mode means setting the pressure regulator of the tractor receiver, for example, MTZ-80, using the pressure gauge as the minimum pressure (or setting the pressure with the pressure amplifier regulator or both), necessary to obtain the dimensions of the groove (track).

The technical solutions indicated in the prototype do not allow them to be used in seeders with a working width of 8, 9, 12, 15, 18 (m) (hereinafter referred to as wide-seeders) because of the insufficient pressure created by the prototype. This is caused by a large loss of air pressure, due to long pneumatic lines (due to the large width of the seeders), their bends, various butt joints, etc. Which does not provide the necessary dimensions of the groove obtained from the prototype. For the same reason, it is not possible to use the prototype in seeders with a working width of 6 m with large wear of the compressor (because with the wear of the compressor its pressure will decrease, and the pressure will not be enough to form the necessary track sizes).

Wide-seeders used today, as well as seeders with a working width of 6 meters or less, incorporate mechanical markers (devices for creating a footprint on the soil), which have load-bearing structures on which there are brackets in which the axes of the disks are located. These load-bearing structures are connected by levers to the rods of hydraulic cylinders that raise and lower the markers. Therefore, markers for wide-seeders today also have dozens of parts. Due to the wide working width and the reinforced load-bearing structure, the weight of the wide-seeder markers significantly exceeds the weight of the seeder markers with a working width of 6 meters. In addition, the length of the markers of the wide-spread seeder significantly exceeds the length of the markers of the seeder with a working width of 6 meters, which, in combination with the increased weight of the markers of the wide-seeder, increases the friction forces upon contact of the marker with the soil, which exceed the friction forces that occur in seeders with a working width of 6 m. By increasing the working width of wide-seeder seeders, the length of their marker devices increases by meters and their weight by tens of kilograms (compared to seeders with a working width of 6 m). What makes us use in cylinders with wide-spread seeders the cylinders for raising (lowering) markers of greater power and, accordingly, greater weight, dimensions and increased oil consumption. Which requires an increase in used power, the use of more powerful tractors (for wide-seeders), and therefore a significant increase in energy consumption. As a result, it significantly increases energy consumption and involves the use of devices that allow to obtain significantly higher pressure at the outlet of the device than that of the prototype, and taking into account air losses due to the long lengths of pneumatic lines or compressor wear. As in the prototype, in the proposed technical solutions there is no mechanical contact with the soil, and the trace from the device will be obtained as a result of a directed air flow under pressure on the soil. The air pressure of the prototype is limited by the compressor power and does not have devices that increase air pressure in its designs. The proposed technical solutions can increase air pressure by 10 or more times, which makes it possible to use them in wide-seeders, as well as in seeders with a working width of 6 m or less, using a more economical mode of operation. In the end, even more significantly reduces energy consumption in seeders, sowing complexes, units than in the prototype. Which does not allow to make any of the technical solutions of the prototype.

The proposed technical solutions in comparison with the technical solutions indicated in the prototype allow to obtain:

- the pressure of the air leaving the device is an order of magnitude and higher and due to this, a more significant reduction in energy costs;

- additional reduction in energy consumption through the use of the optimal pressure setting mode, as well as the other above advantages.

Obtaining the above technical results allows the design of the device, consisting of a trunk, two switches, two autonomous channels. The technical result is achieved due to the fact that the input of the pressure amplifier is connected to the line, and its output to the input of the connector, the outputs of which are connected to the inputs of the switches, the outputs of which are connected to autonomous channels.

Today, a rather large range of pressure amplifiers with a pressure amplification factor of up to 4 times or more is produced (for example, a pressure amplifier like “Maximator” (see “INTERNET”) allows you to compress air up to 350 bar or 34.55 MPa). And the pressure booster EVBA 1110-4100, has a weight of 0.98 kg; output / inlet pressure ratio - 4: 1; operating temperature 2-50 (° C); has a built-in pressure regulator, providing a constant pressure at the exit; Supplier of Promsnab74 LLC, 456318, Chelyabinsk Region, Miass, ul. Vernadsky, house No. 5, office 8. Pressure amplifiers are also manufactured by Camozzi S.P.A. (Italy) (see INTERNET): MPLV - pressure amplification factor 1: 4; GPLV - pressure gain 1: 5; SPLV10 - pressure gain 1:10. Thus, using a pressure amplifier in conjunction with other structural elements of the proposed device, we obtain pressure at the outlet of the device an order of magnitude and higher than that produced by a compressor, for example, an MTZ-80 tractor (0.73-0.76 MPa). The prototype does not have in its composition and significant differences the pressure amplifier and the relationship with other structural elements, which does not allow it to develop such a high pressure at the outlet and does not make it possible to use it in wide-seeders and, accordingly, reduce energy costs in them. The proposed device allows its use in wide-seeders, as well as in seeders with a working width of 6 m or less, to significantly reduce energy consumption, including through the use of the optimal pressure setting mode. Seeders of the prototype (with a working width of 6 m) do not allow to use the optimal pressure setting mode, because due to pressure loss due to the long length of the pneumatic line (approximately 2 m from the pressure source to the exit from the tractor cab, for example, MTZ-80, plus approximately 5 m - from the tractor cab to the extreme opener of a 6 m working width of the seeder, plus the take-off length of the holder of the autonomous channel (hose, sleeve, etc.) 2.73 m) and wear of the compressor working elements. Total total length of one pneumatic line is 9.73 m (with a row spacing of 0.25 m and a distance between the middle of the front wheels of 0.8 m). The extension length of the holder of the autonomous channel (hose, sleeve, etc.) is the distance from the center of the extreme opener of the seeder to the center of the hole of the autonomous channel (or the center of the nozzle hole, if this is an embodiment of the device). For wide-seeders, the length of one pneumatic line increases even more significantly. According to the information from the INTERNET system (Blasting: “The main elements of the abrasive system”), the pressure loss for our length of the pneumatic line can be up to 0.0721 MPa plus the pressure loss from the bends is 0.0101 MPa from each bend, and there are 5 of them , 0505 MPa, which will total 0.1226 MPA. Even without considering the pressure loss in various connections, that is, with a new compressor, the prototype works at its limit (in the sense that there is hardly enough pressure to get a groove). There is a certain fleet of tractors where the compressor creates a pressure of not more than 0.4 MPa (a worn compressor). The experimental work with the device without nozzles carried out at such a pressure (0.4 MPa) of the MTZ-80 tractor showed that the required groove size is not obtained. Thus, the prototype does not allow: to use the optimal pressure mode; applications in wide seeders; reduce energy costs.

Pressure adjustment can be carried out either as a tractor pressure regulator or as a pressure regulator built into the pressure amplifier.

In the proposed technical solution, the line is designed to connect a pressure source to a pressure amplifier and supply air from a pressure source of air to the pressure amplifier. As a highway, for example, a hose with FUBAC 170111 rapid connectors can be used, which is connected with one fitting, for example, to the receiver output or tractor pressure regulator, etc., and the second fitting is connected to the pressure amplifier input. Also, as a highway, autonomous channels can be used: pipe with welded fittings or nipples or one nipple or one fitting at the end; sleeve with union nuts at the ends or with fittings or nipples or one nipple with one fitting at the ends; a pipe through a fitting connected to a hose; rubber hose with fittings or nipples at the ends; dozens of high pressure hoses, depending on GOST 15150-69 and GOST 6286-73, with quick-disconnect connections or not; or generally according to technical conditions, etc. The pressure booster is designed to amplify, control and transmit air flow to the connector. As a pressure enhancer, for example, EVBA 1110-4100 (increases pressure 4 times) or another, depending on the required parameters, can be used. The connector is designed to connect the pressure amplifier to the switches and to supply air from the pressure amplifier to the switches. As a connector, for example, a tee, a tee with a hose (which can be connected to a tractor pressure regulator), a tee with two metal tubes, a tee with two metal tubes and one hose, a tee with hoses and Rapid fittings FUBAC 170111 and etc., there may be dozens of options. As a tee, anyone can be used according to GOST 8949-75 or any other that is suitable according to technical conditions. Switches are used to alternately switch channels with the aim of supplying and directing air either through one autonomous channel or sometimes through another. As switches, for example, ball valves of the type 11B41p (PN1.6 MPa), 11s38p (PN16MPa), etc. can be used. production of JSC PAZ, 440007, Russia, Penza, ul. Transport, 1, www.armatura-paz.ru). info @ 99-t / ru) or others. The switches can have pneumatic, mechanical, electro-pneumatic, electromagnetic and other controls. The switches can be located both inside and outside the tractor cab. Everything will depend on the layout and design of the switches. Autonomous channels are designed to provide air movement from the switches to the soil and the formation of a trace on it. An autonomous channel can be, for example, a hose with FUBAC 170111 rapid connectors (moreover, the fitting is only on one side). When air passes from a pressure source through a highway, through a pressure amplifier, through a connector, through a switch and one of the autonomous channels, a reinforced (several times or an order of magnitude) air stream acts on the soil, forming a trail. What the prototype does not allow, because in its design there is no pressure amplifier where the input of the pressure amplifier is connected to the line, and its output is to the input of the connector, the outputs of which are connected to the inputs of the switches, the outputs of which are connected to autonomous channels.

Analysis of the above structural elements of the proposed device shows that any of its elements cannot work autonomously to obtain a trace on the soil, just as the absence of one of the structural elements makes it inoperative. Therefore, only in the presence of all structural elements that are interconnected with each other (significant differences) and allows you to reduce energy consumption and get other technical results indicated above.

The composition of the embodiment of the device is similar to the composition of the device. The technical result is achieved due to the fact that at the end of each of the two autonomous channels there is a nozzle connected to the autonomous channel, and also due to the fact that the input of the pressure amplifier is connected to the line, and its output to the input of the connector, the outputs of which are connected to the inputs of the switches, the outputs of which are connected to autonomous channels. That allows you to increase the pressure by an order of magnitude of the embodiment of the device, compared with the prototype, if you use, for example, nozzles that increase pressure by 2.5 times, and pressure amplifiers that increase pressure by 4 times and, accordingly, significantly reduce energy consumption. What the prototype does not allow. Significant differences in the embodiment of the device, together with significant differences in the device itself, can further increase the pressure of the air stream and, due to this, use them in the most wide-spread seeders, aggregates, complexes and, accordingly, more significantly reduce energy resources.

For example, the company “WORTH GROUP” (www.wuerth.ru, “Würth-Rus,” plus 7 (495) 50570071) supplies nozzle nozzles with 9 holes. The mass of one nozzle is 20 g. Tykon LLC, 121614, Moscow, ul. Krylatsky Hills 35, bldg. 1 supplies nozzles - air nozzles, for example

Due to the fact that at the end of each of the two autonomous channels there is a nozzle connected to the autonomous channel, as well as due to significant differences between the main device and its components, weakened air pressure due to various losses, including long autonomous channels of wide-spread seeders entering the nozzle is significantly enhanced. Coming out of the nozzle, a reinforced stream of air acts on the soil, forming a trail. What the prototype does not allow, since it does not have a nozzle located at the end of each autonomous channel and connected to it. That is, a line, a pressure amplifier, a connector, switches, autonomous channels and nozzles, structurally connected into a single device, in interaction with each other, and also due to the fact that at the end of each of the two autonomous channels there is a nozzle connected to the autonomous channel substantially increase pressure, allow use in the most wide-spread seeders, reduce energy consumption and give additional technical results indicated above. Analysis of the above structural elements shows that any of its elements cannot work autonomously to obtain a trace on the soil, and the absence of one of the structural elements makes it inoperative.

The use of the proposed significant differences (features) in the above structural technical solutions will reduce energy costs and obtain a number of other technical results indicated earlier.

The set of distinctive features of the claimed devices is not found in patent information, scientific and technical literature and manufactured products. Therefore, the proposed device has significant features and meet the condition of patentability for "novelty."

Utility Model Implementation

The devices of FIG. 1 and FIG. 2 are intended to form a footprint in the soil by applying a pressure of an air stream to the soil. In all devices, line 1 is designed to connect the pressure source to pressure amplifier 2 and supply air from the source (either directly to the tractor compressor or receiver or through some additional elements) of air pressure to pressure amplifier 2. Pressure amplifier 2 is designed to amplify, control air pressure and transferring it to connector 3. Connector 3 is used to connect pressure amplifier 2 to switches 4, as well as transmitting air flow from pressure amplifier 2 to switch 4. The switch 4 are used to alternately switch the channels for supplying and guiding the air that one autonomous channel 5, then over another. The switches 4 may have pneumatic, mechanical, electro-pneumatic, electromagnetic and other controls. Autonomous channels 5 are designed to provide air movement from the switch 4 to the soil and the formation of a trace on it (if this is the device of Fig. 1) and to the nozzles 6, if this device of Fig. 2. Nozzles 6 are designed to enhance air flow and its subsequent direct impact on the soil to form a trace.

The device (Fig. 1) contains a highway 1, two switches 4, two autonomous channels 5. Technical results are achieved due to the fact that the input of the pressure amplifier 2 is connected to the highway 1, and its output is to the input of the connector 3, the outputs of which are connected to the inputs of the switches 4, the outputs of which are connected to autonomous channels 5.

In working condition, for example, a hose with Rapid fittings FUBAC 170111 - line 1 is connected to the pressure regulator of the tractor receiver, for example, MTZ-80, with one end and connected to the input of a pressure amplifier 2, for example, type EVBA 1110- 4100 (with pressure regulator). The connector 3 in this example is a tee, at the ends of which there are tubes with threaded ends connected to a tee and the third hole of the tee is connected to a hose with a fitting at the end. With the help of a hose using a fitting - connector 3, the output of pressure amplifier 2 is connected. Adapters and other elements can be used in the connections. The threaded ends of the connector 3 are connected to the inputs of the switches 4. As switches 4, for example, ball valves of the type 11B41p (PN1.6MPa), 11s38p (PN16MPa), etc. can be used. production of JSC PAZ, 440007, Russia, Penza, ul. Transport, 1, www.armatura-paz.ru, info @ 99-t / ru, or others. And the switches 4 are connected to two autonomous channels 5. The autonomous channel 5 can be, for example, a hose with FUBAC 170111 rapid connectors (moreover, the fitting is only on one side). Having prepared the equipment for work and checking its working condition, the tractor driver starts the tractor, sets the pressure in the pressure regulator of the tractor receiver or in pressure amplifier 2, for example, type EVBA 1110-4100 pressure regulator (or both on the pressure gauge). Then, the tractor driver turns the control handle of the left switch 4 all the way, thereby opening the ball valve, for example, 11s38p, while the air flow coming out, for example, from the receiver of the MTZ-80 tractor passes through highway 1 (for example, through the FUBAC 170111 hose), through pressure amplifier 2 (for example, EVBA 1110-4100), through connector 3 (for example, the assembly unit described above), through switch 4 (for example, ball valve 11s38p), through the left autonomous channel 5 (hose with FUBAC 170111 rapid connectors , and the fitting is only on one side), it turns out of him, and his jet acting on the ground, leaving her groove. At this time, the right switch 4 (for example, the ball valve 11s38p) is closed and the air flow from, for example, the tractor receiver reaches only the right switch 4 and does not go anywhere else. After the tractor driver has sowed the first lane of the field to the end, he turns around in order to sow the next lane adjacent to the first. At this moment, he turns the same handle of the left switch 4 in the opposite direction (closes this valve), and with the handle of the right switch 4 opens the ball valve. At the same time, the air flow from, for example, the tractor receiver reaching the left switch 4 does not go further (since the valve is closed), and since the ball valve is open (right switch 4), the air flow passing through it and the autonomous channel 5 exiting it , impacts with its jet on the soil, leaves a groove on it. And then the cycle repeats. This design and operation of the device of FIG. 1 allows you to significantly increase air pressure, use it in wide-seeders, and, therefore, reduce energy consumption. What the prototype does not allow, because in its design there is no pressure amplifier 2, other structural elements that are interconnected with each other and representing a single device. As a result, it limits the pressure of the jet of air leaving the prototype and does not allow its use in wide-spreader seeders, as well as using the optimal pressure mode, does not give such a reduction in energy consumption as the proposed device of FIG. one.

As a highway 1, two autonomous channels 5 can be used, for example, a hose with fittings "rapid" FUBAC 170111, PN 2.0 MPa. Supplier of All Instruments.ru LLC, 109451, Moscow, ul. Bratislavskaya, d.16, building 1, room 3, t. Plus 7 (499) 681-23-57. A large range of hoses and high pressure hoses is supplied and manufactured by Astra LLC, Moscow, ul. General Dorokhov, d. 6, t. Plus 7 (495) 255-17-85, which operate in the temperature range from minus 50 ° C to plus 100 ° C, the length can be from 100 mm to 200 m, DN from 5 to 76 mm, working pressure up to 100 MPa (1000 atm). Instead of hoses, threaded tubes at the ends or other elements can be used. The pressure booster 2 can be rigidly fixed on the bracket and the switches 4 can be fixed on it. And the bracket can be rigidly fixed with a bracket to the fixed part of the steering column of the tractor, for example, MTZ-80. Moreover, the switches 4 should be positioned relative to the steering column so that only the left switch 4 is to the left of it and the right switch 4 is to the right, the ball valve handles should be located in a convenient place for the tractor operator’s hands. The switches 4 can be located both inside the tractor cab and outside. Everything will depend on the layout and design of the switches 4. The pressure regulator of the receiver of the tractor or the pressure regulator of pressure amplifier 2 (or both at the same time) can set the minimum pressure necessary to obtain the dimensions of the track (optimal pressure mode).

Highway 1, pressure amplifier 2, connector 3, switches 4, autonomous channels 5 structurally connected in a single device by their above significant differences and in interaction with each other allow to reduce energy consumption compared to the prototype and other analogues, as well as to obtain additional technical results indicated above.

In addition, the proposed technical solution allows additional energy savings by regulating the pressure with a pressure regulator of a pressure amplifier 2 (which is supplied with a pressure amplifier 2 and is built into its pneumatic system, for example, in a pressure amplifier EVBA 1110-4100) and regulate the pressure using a pressure regulator on the tractor receiver. What does not allow to make a prototype. That is, using the pressure regulator, you can set the minimum pressure, which allows you to obtain the necessary dimensions of the groove (trace).

The composition of the device of FIG. 2 is similar to the composition of the device of FIG. one.

The technical result of the device of FIG. 2 is achieved due to the fact that at the end of each of the two autonomous channels 5 there is a nozzle 6 connected to the autonomous channel 5, and also due to the fact that the input of the pressure amplifier 2 is connected to the highway 1, and its output is to the input of the connector 3, the outputs of which connected to the inputs of the switches 4, the outputs of which are connected to autonomous channels 5. This allows to increase the pressure from the device of FIG. 2, compared with the prototype, if you use, for example, nozzles 6, which increase the pressure, for example 2.5 times, and pressure amplifiers 2, which increase the pressure, for example 4 times, and accordingly significantly reduce energy consumption. What does not allow the design of the prototype, due to the lack of the fact that at the end of each of the two autonomous channels 5 there is a nozzle 6 connected to the autonomous channel 5.

In operation, the device of FIG. 2 differs from the device of FIG. 1 by the fact that as a standalone channel 5, a hose with FUBAC 170111 rapid connectors at the ends can be used and the second end of the hose is connected with the nozzle 6 with the nozzle 6, for example, BSPTFA-PP15. The operation of the device of FIG. 2 is similar to the operation of the device of FIG. 1. The difference is that in the device of FIG. 2, the air flow in a finite period of time leaves the nozzle 6 and acts on the soil, forming a trace, and not from an autonomous channel 5 (as in the device of Fig. 1). The design of the connection of the autonomous channels 5 and nozzles 6, as well as the autonomous channels 5 and nozzles 6 may be different. Both autonomous channels 5 and nozzles 6 will be fixed on the seeders supporting elements (for example, by pressing) and will protrude beyond the seeder’s working width at a distance necessary for finding a furrow (track).

Used in the proposed devices of FIG. 1 and FIG. 2 highway 1, pressure amplifier 2, connector 3, switches 4, autonomous channels 5, nozzles 6 are supplied today by various enterprises (indicated above), assembled using a universal tool (wrenches, screwdrivers, etc.). Assembled, all the proposed devices without technical problems are connected to the pneumatic system of the tractor, and placed on wide-seeders. Which corresponds to the patentability condition for “industrial applicability”.

Analysis of the above proposed device designs of FIG. 1 and FIG. 2 shows that any of the elements of these structures cannot work autonomously to obtain a trace on the soil. Only in the collection and interconnection of the above structural elements is it possible to obtain the above technical results.

The use in FIG. 1 of FIG. 2 proposed significant differences (features) will reduce energy costs and get a number of other technical results, indicated earlier. The proposed technical solutions contain new devices that are absent from the prototype: pressure amplifier 2, nozzles 6 and various new connections between the elements and their relative positions (significant differences), which ultimately provides higher technical results than the prototype.

The set of distinctive features of the claimed devices is not found in patent information, scientific and technical literature and manufactured products. Therefore, the proposed device has significant features and meet the condition of patentability for "novelty."
