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.

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, 18 (m)), as well as in seeders with a working width of 6 m (with large compressor wear), which does not leads to a reduction in 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 (incoming lubrication devices); reduce the amount of hydraulic fluid used by 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 booster.

By using the optimal pressure setting mode, it is understood that the pressure regulator of the tractor receiver, for example, MTZ-80, sets the minimum pressure (either pressure setting with the pressure amplifier regulator, or both) to obtain the dimensions of the groove (trace).

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) due to the insufficiency of the 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 impossible to use the prototype in seeders with a working width of 6 m or less with large compressor wear (because with the compressor wear, the pressure that it gives out will decrease, and the pressure will not be enough to form the necessary trace sizes).

Wide-seeders used today, as well as seeders with a working width of 6 meters or less, incorporate mechanical devices that have load-bearing structures, on which brackets are located, in which the axes of the disc assembly are located. These load-bearing structures are connected by levers to the rods of hydraulic cylinders that carry out the raising and lowering of the devices. Therefore, devices of wide-seeders today also have dozens of parts. The weight of the wide-seeder devices due to the large working width and the reinforced supporting structure significantly exceeds the weight of the seeder devices with a working width of 6 meters. In addition, the length of the wide-seeder devices significantly exceeds the length of the seeder devices with a working width of 6 meters, which in combination with the increased weight of the wide-seeder devices increases the friction forces when the device contacts the soil (which exceed the friction forces that occur in seeders with a working width of 6 m or less ) With an increase in the working width of wide-seeders, the length of their devices increases by meters, and their weight increases by tens of kilograms (compared to seeders with a working width of 6 m or less). Which makes it necessary to use hydraulic cylinders for raising (lowering) devices of greater power, respectively, greater weight, dimensions and increased oil consumption in wide-seeder seeders and to use larger power tractors for wide-seeder seeders. 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, the devices during operation do not have 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 make it possible to increase air pressure by a factor of 10 or more, 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 operating mode. 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, switch, 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 through the intermediate element is connected to the input of the switch, the output of which is 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. On the contrary, 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 lines (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 working width of 6 m seeder, plus a take-off length of the holder of an 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 information from the INTERNET system (Blasting: “The main elements of an abrasive system”), the pressure loss for our length of pneumatic lines can be up to 0.0721 MPa plus the pressure loss from bends is 0.0101 MPa from each bend, and we have 5 and it turns out 0.0505 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 carried out at the MT3-80 tractor at this pressure with the device without nozzles showed that the required groove size is not obtained. Thus, the prototype does not allow the use of the optimal pressure mode, and does not work with a worn compressor, and cannot be used in wide-spreader seeders, which means reducing energy costs.

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

In the proposed technical solution, the line is designed to supply air from an air pressure source to a 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 trunk, an intermediate element, autonomous channels can be used: pipe with welded fittings or nipples or one nipple with one fitting at the ends; 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; adapters of various types; 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 amplifier is designed to amplify, control and transmit air flow from the line to the intermediate element. As a pressure enhancer, for example, EVBA 1110-4100 or another (depending on the required parameters), which enhances the pressure by 4 times, can be used. The intermediate element is designed to connect the pressure amplifier and the switch and transmit the air flow from the pressure amplifier to the switch. The intermediate element can be a hose with FUBAC 170111 rapid connectors. The switch is used to alternately switch channels with the aim of supplying and directing air through one independent channel or another. As a switch, for example, a B71-22 type pneumatic valve can be used (supplier of NP Technodress SD, Sverdlovsk Region, Yekaterinburg, N. Onufrieva, 55; tel. (343) 361-55-98, (343) 361-85-99; info @ 99-t / ru) or another. In addition, three-way cranes and dozens of other types of valves, pneumatics, and pneumatic automation can be used as switches. 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 switch 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 an intermediate element, through a switch and one of the autonomous channels, a reinforced air stream acts on the soil, forming a trail. As a result, we obtain the pressure at the outlet of the autonomous channel by an order of magnitude and higher, which allows us to use the device in wide-spreader seeders, reduce energy consumption, get an additional reduction in energy consumption through the use of the optimal pressure setting mode, as well as the other above-mentioned advantages. What the prototype does not allow, because in its design there is no pressure amplifier connected to other components, which together with other elements make up a single device. Which ultimately limits the pressure of the jet of air leaving the prototype and does not allow it to be used in wide-spreader seeders, as well as to use the optimum pressure mode and, accordingly, reduce energy costs. 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 main line, and its output through the intermediate element is connected to the input of the switch, the output of which connected to autonomous channels. That allows an order of magnitude to increase the pressure 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, which increase pressure by 4 times and, accordingly, significantly reduce energy consumption. What does not allow to make a prototype. 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, significantly reduce energy costs.

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 air nozzles, for example

BSPTFA-PP15 weighing 120 g with a high-speed intense high-pressure flow with a capacity of 0.7 atm - 194 l / min; at 2 atm - 358 l / min; at 4 atm - 587 l / min; at 6 atm - 817 l / min.

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, an intermediate element, a switch, autonomous channels and nozzles connected structurally 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 an autonomous channel, reduce energy costs and obtain 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 proposed technical solutions contain new devices that are absent from the prototype: pressure amplifier, nozzles and a new element: an intermediate element, as well as 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."

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 supply air from an air pressure source (either directly from the tractor compressor or receiver or through some additional elements) to pressure amplifier 2. Pressure amplifier 2 is designed to amplify, regulate air pressure and transmit it through an intermediate element 3 into switch 4. Intermediate 3 is used to connect pressure amplifier 2 and switch 4 and transmit air flow from pressure amplifier 2 to switch 4. Switch 4 serves t for alternately switching 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 to form a trace (if this device is FIG. 1) and to nozzles 6, if this device is 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, switch 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 through an intermediate element 3 is connected to the input of the switch 4, the output of which 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 same hose, using a fitting - intermediate element 3, connects the output of a pressure amplifier 2, for example, type EVBA 1110-4100, and the second hose fitting (intermediate element 3) - connects to the input of a valve type B71-22 valve distributor 4. switch 4. In connection adapters and other elements should be used. And already, two FUBAC 170111 hoses (with one rapid connection at the end of each hose) are connected to the outputs of a B71-22 type valve (switch 4) - two independent channels 5. Pressure in a pressure amplifier 2, for example, type EVBA 1110-4100 set by pressure gauge. 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 receiver of the tractor or in the pressure amplifier 2, for example, type EVBA 1110-4100 pressure regulator (or both). Then, the tractor driver turns the control handle of switch 4, if, for example, the valve distributor B71-22 to the left, while the air flow coming out, for example, from the receiver of the MTZ-80 tractor passes through line 1 (for example, through a FUBAC 170111 hose), through an amplifier pressure 2 (for example, type EVBA 1110-4100), through an intermediate element 3 (for example, a FUBAC 170111 hose), through switch 4 (for example, a valve distributor B71-22), through the first stand-alone channel 5 (if it is, for example, a FUBAC hose 170111), leaves it and, acting with its jet on and the soil leaves a groove on it. At this time, the second channel of the valve valve B71-22 (switch 4) is blocked and the air flow from, for example, the tractor receiver through line 1, pressure amplifier 2, intermediate element 3 and switch 4 does not enter the second autonomous channel 5. After the tractor driver has sowed the first lane of the field to the end; he is turning in order to sow the next lane adjacent to the first. At this moment, he rotates the same handle of the switch 4 (for example, control valve B71-22 valve) in the opposite direction. In this case, the air flow from, for example, the receiver through the highway 1, through the pressure amplifier 2, through the intermediate element 3, through the switch 4, through the second autonomous channel 5 leaves it, and acting on the soil with its jet, leaves a groove on it. And then the cycle repeats. This design and operation of the device of FIG. 1 allow 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, the input of which is connected to the highway 1, and its output through the intermediate element 3 is connected to the input of the switch 4, the output of which is connected to the autonomous channels 5. Which ultimately limits the pressure of the jet air coming out of the prototype and does not allow its use in wide-seeders, and also use the optimal pressure mode and, accordingly, does not give such a reduction in energy consumption.

As a line 1, an intermediate element 3 and two autonomous channels 5, for example, a hose with Rapid fittings FUBAC 170111, PN 2.0 MPa can be used. 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). If, for example, a B71-22 crane pneumatic distributor is used, then it, together with pressure amplifier 2, can be rigidly fixed to the bracket. And the bracket is rigidly fixed with a bracket to the fixed part of the steering column of the tractor, for example, MTZ-80. Moreover, the crank pneumatic distributor B71-22 control handle should be located in a convenient place for the tractor operator. 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. The switch 4 can be located both inside the tractor cab and beyond. Everything will depend on the layout and design of switch 4. Both stand-alone channels 5 and nozzles 6 will be fixed to the seeders supporting elements (for example, by pressing) and will protrude beyond the seeder’s working width at a distance necessary to find the groove (trace). The pressure regulator of the tractor receiver or the pressure regulator of pressure amplifier 2 (or both at the same time) can be used to set the minimum pressure necessary to obtain the dimensions of the track (optimal pressure mode).

Highway 1, pressure amplifier 2, intermediate element 3, switch 4, autonomous channels 5, structurally connected in a single device by their above significant differences and in interaction with each other, can reduce energy consumption compared to the prototype and other analogs, as well as obtain additional technical results mentioned above. This can be done because in the design of the prototype there is no new device: pressure amplifier 2 and a new element: intermediate element 3, as well as their location and relationship. 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 receiver of the tractor, which does not allow you 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. 1. 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 (for which, for example, a BSPTFA-PP15 nozzle can be used) connected to the autonomous channel 5, and also due to the fact that the input of the pressure amplifier 2 connected to the highway 1, and its output through the intermediate element 3 is connected to the input of the switch 4, the output of which is 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 the prototype construction does not allow due to the lack of a nozzle 6 located at the end of each of the two autonomous channels 5 connected to the autonomous channel 5, which allows FIG. 2 to obtain pressure an order of magnitude and higher than that of the prototype, and reduce energy consumption more than what the prototype allows.

In operation, the device of FIG. 2 differs from the device of FIG. 1 in that as a stand-alone channel 3, a hose with FUBAC 170111 rapid connectors at the ends can be used, and the second end of the hose is connected to the nozzle 4 using a rapid connector, 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).

Used in the proposed devices of FIG. 1 and FIG. 2 line 1, pressure amplifier 2, intermediate element 3, switch 4, autonomous channels 5, nozzles 6 are today supplied 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 assembly and in the 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 a new element: intermediate element 3, as well as 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."
