Description

The technical field to which the utility model relates.

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 Tc - M multipurpose pneumatic precision seeder for row crops, model 8000 (manufacturer ZAO Technika - Service, Voronezh, Pr-t Patriotov, 75, http://www.tese.ru). The disadvantage of this device is:

- increased energy consumption due to increased weight, as well as high friction forces that occur when it comes into contact with the soil.

Another analogue is the device used in the AMAZONE D9 and AD3 seeders manufactured by AMAZONEN-WERKE H. DREYER GmbH & Co.KG Germany, http://www.amazone.ru, the disadvantage of which is the same as that of model 8000.

Another analogue is the device used in the universal pneumatic seeder type С - 6ПМ2 (produced by Radiozavod OJSC, 440039, Penza, Baidukova St., 1). The disadvantage of this analogue is the same as that of the 8000.

The closest analogue (prototype) of the claimed technical solution is the device used in the seeder universal pneumatic trailed, patent for utility model No. 112585 from 08/31/2011

The disadvantage of the prototype:

- increased energy consumption due to the increased weight of the device, as well as the large friction forces that occur when it comes into contact with the soil.

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, as 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 raising markers; 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; to increase the productivity of sowing complexes, aggregates, seeders by reducing the switching time of devices and the absence of their lifting (lowering); increase the capacity of the hopper or the width of the seeders, complexes, aggregates.

Utility model No. 112585 dated 08/31/2011 and its analogs include so-called markers (devices for creating a footprint on the soil) having load-bearing structures on which brackets are located, in which are the axes of the disks assembly. These load-bearing structures are connected by levers to the rods of hydraulic cylinders that raise and lower the markers. A large design range of seed drills, complexes, aggregates has similar bearing marker designs as for the TS-M8000A seeder (including those used in utility model No. 112585 of 08/31/2011) that can withstand both the efforts of powerful hydraulic cylinders and the loads mechanical contact of the disk with the soil. These factors make it necessary to have a supporting structure consisting of 64 parts in each marker of the TS-M8000A seeder. Accordingly, the two supporting structures are composed of 128 parts, which gives significant weight. Moreover, the greater the width of the seeder, the greater the weight of the supporting structures. The supporting structure of the device according to the invention can be made, for example, in the form of a light aluminum corner, on which, for example, a light plastic hose (stand-alone channel) fixed in several places with plastic locks. The options for the execution of the supporting structure may be different.

In accordance with the catalog of parts and assembly units of the TS-M8000A seeder (see coordinates of the first analogue), the right marker SN-8.57.00.00.000-01 of the seeder SN-8.00.00.000 contains 91 parts, as well as the left one.

Thus, both markers have more than 182 parts. Any of the proposed devices will have at least ten times fewer parts (this can be seen from the proposed structural diagrams and formulas) and, accordingly, significantly less weight. Today, mechanical markers are used in the seeders and other agricultural machinery, the disc of which leaves contact with the soil groove. Disadvantages of mechanical markers: increased weight and high friction forces when the marker is in direct contact with the soil reduce the tractor's pulling force and increase energy consumption, which is not available in the proposed devices primarily due to the lack of mechanical contact with the soil, since the track from the device will result from the directional air flow under pressure on the soil. In addition, today the used disks are assembled, making direct contact with the soil to form a groove (there are two of them in the TS-M8000A seeder with a total of 54 parts), which are completely absent in the proposed technical solutions, which also reduces the weight of, for example, seeders. As a result, the proposed devices allow, due to: the absence of mechanical contact with the soil, a significant reduction in the weight of both the devices themselves and the units used today in seeders (aggregates, complexes), as well as the exclusion of operations to raise (lower) the markers, to reduce energy costs.

To obtain the above technical results, the design of the device may have several options and designs.

In the first embodiment, the device includes load-bearing elements, a trunk, a switch, two autonomous channels. Technical results are achieved due to the fact that:

- the device is made in the form of two autonomous channels connected to the output of the switch, the input of which is connected to the highway.

Today, the seeders use a large range of fans, significantly different from each other in pressure, performance and other parameters. So, for example, the fan of the Ukrainian enterprise of PJSC Chervona Zirka (25006, Kirovograd, 1 Mendeleev St.) is 1.75 times higher in terms of capacity and pressure of the fan produced by the enterprise OJSC Radiozavod (Russia, 440039, Penza, Baidukova St., 1). This allows you to use the "excess" fan power to operate the proposed devices. In relation to the first embodiment, the real device will have the following form. As one of the possible options, when the second end, for example, of a rubber hose (line) of the device is worn, for example, on a fitting welded to the inside of the fan housing and secured to it, for example, with a clamp or other fixing element. The connection point of the hose (line) of the device, as well as parts or assemblies on which the hose (line) is worn, can be very different. For example, it can be part of the pneumatic system of the seeder or part of the box, etc. The other end of the hose (line) can be dressed on a fitting, also fixed with a fastener, and the fitting can be screwed into a switch (the input of the switch is connected to the line), for which, for example, a valve type B71-22 valve can be used, or pneumatic valve or pneumatic distributor with various control systems, etc. (hereinafter the directional valve). If, for example, a valve valve type B71-22 is used as a switch, then it will be located in the tractor cabin. Each working output of the switch (and there will be two) will be connected to a fitting on which a hose can be put on (autonomous channel) and secured with a clamp or other structural element (autonomous channels connected to the output of the switch). The second ends of these hoses (autonomous channels) can be located on the supporting elements, or can be connected to the pipe. Options may be different. In the above example of the first embodiment, the second end of the highway is connected to the fan part, due to which part of the air flow passing through the highway, the switch and one of the autonomous channels acts on the soil, forming a trace on it. The switch is used to alternately switch channels with the aim of supplying and directing air, either through one independent channel or sometimes through another. That is, the trunk, switch and autonomous channels connected structurally in interaction with each other provide a solution to the same problem as mechanical markers: leave a mark on the ground, but can reduce energy costs and get additional technical results mentioned above. However, the tractor’s additional energy resources are not involved, that is, the “excess” fan power is used to operate the proposed devices.

The design of the proposed device, made in the form of two autonomous channels connected to the output of the switch, the input of which is connected to the highway, works from an air source or a gaseous mixture. In the future, only air will be referred to in the text. The device is designed to form a footprint on the soil by applying a pressure of a stream of air passing from the highway through a switch, alternately to one autonomous channel, then to another autonomous channel using a switch that controls air flow.

The line is designed to supply air from a source of air pressure to the switch. The switch is designed to switch channels and air supply to one autonomous channel, then to another. Autonomous channels are designed to provide air movement from the switch to its outlet and direct it to the soil. An analysis of the above structural elements shows that any of these elements cannot work autonomously to obtain a trace on the soil. Only in the collection and in the relationship between the above structural elements is it possible to obtain the above results.

For the operation of markers of utility model No. 112585 dated 08/31/2011 and other analogs, hydraulic cylinders (receiving oil pressure from the hydraulic pump through the hydraulic system and performing alternate raising and lowering of the markers) are required, connected by levers with the supporting structure of the markers, discs assembled (located on bearing construction of markers), a hydraulic pump, as well as a control device in the form of a hydraulic distributor. Only the presence of these devices in conjunction provide a trace on the ground.

Comparing the design of the proposed device with the design of the markers of utility model No. 112585 of 08/31/2011 and other analogues, we conclude the following:

1. Due to the fact that the proposed device is made in the form of two autonomous channels connected to the output of the switch, the input of which is connected to the highway, it does not require mechanical contact with the soil, since only air under pressure is needed on the soil to form a trace. And air is used from the “excess” power of the fan, without using the tractor’s energy resources.

In utility model No. 112585 dated 08/31/2011 and other analogs, for the formation of a footprint on the soil, a mechanical contact of the marker disc with the soil is necessary, creating large friction forces, which on the one hand increase the tractor’s energy consumption, and, on the other hand, break down due to stresses individual parts and components of markers, the restoration of which requires additional energy resources.

2. In the proposed device, the air from, for example, a fan through a highway connected to the input of the switch, which switches the channels and delivers the air alternately to one autonomous channel, then to another, connected to the output of the switch. At the same time, autonomous channels are located and fixed on light supporting structures rigidly fixed at the time of operation, for example, on the coulter beams of the seeder and at the required distance from them. If, for example, a manual pneumatic distributor is used as a switch, then the tractor driver turns his handle either left or right. At the same time, additional tractor energy resources are not used to switch channels and obtain a trace on the soil.

In utility model No. 112585 dated 08/31/2011 and other analogs, for the left marker to stop working and the right marker to start working, it is necessary that the left marker hydraulic cylinder lifts the left marker vertically and the right marker hydraulic cylinder lowers the right marker down. Switching is provided by a hydrodistributor, and the oil is supplied under pressure by a hydraulic pump through a hydraulic system. In this case, the hydraulic pump uses the tractor’s energy resources. In addition, the slow operation of the valve with the hydraulic system also requires energy, which does not require a switch, the input of which is connected to the highway, and the outputs with autonomous channels in the proposed device.

3. As previously noted and described, the proposed device due to its design (made in the form of two autonomous channels connected to the output of the switch, the input of which is connected to the highway), has a small weight and practically does not affect the traction of the tractor, and therefore does not use additional energy resources.

The weight of the markers considered by the wound on the example of the marker SN-8.57.00.00.000-01 of the seeder SN-8.00.00.000 (TS-M8000A) has a significant weight and affects the tractor's pulling force, and, therefore, uses additional energy resources. In addition, the weight of two hydraulic cylinders with a part of the hydraulic system (metal or metal-rubber pipelines with hydraulic elements) also affects the traction of the tractor and, therefore, uses additional energy resources.

Thus, the trunk, switch and autonomous channels connected structurally into a single device by their abovementioned essential features make it possible to reduce energy consumption compared to markers and other analogs used in utility model No. 112585 of 08/31/2011.

In the second embodiment, the device consists of supporting elements, two autonomous channels, two switches, trunk. The version contains a compressor. Technical results in the second embodiment are achieved due to the fact that:

- the device is made in the form of two autonomous channels connected to the outputs of the switches, the inputs of which are connected to a common highway;

- contains a compressor, the output of which is connected to the input of the highway (execution).

Today, operated mechanical markers often fail. This is the failure of the bearings with an increase in the size of the holes for the bearing, separation of the disk stop, a break in the axis of the disk and the bracket for the axis and so on. What forces the tractor driver to leave for the not plowed part of the field for disassembling, welding, etc. in a word, to restore broken parts and assemblies, and then again return to the site of the interrupted sowing. Additional turning the tractor on and off, as well as forced idle movements associated with the repair, additionally expended energy resources for the repair (for example, welding, drilling, etc.) - all this significantly increases energy costs. The proposed device due to its design, made in the form of two autonomous channels connected to the outputs of the switches, the inputs of which are connected to a common highway, has no contact with the soil and avoids energy costs associated with the repair of used markers. In addition, to ensure the complete absence of energy consumption for the repair of the proposed device, a second switch is used, the output of which is connected to an autonomous channel, and the input of the switch is connected to a common trunk. This allows in the field, and without leaving the tractor to repair the switch. If, for example, type B71-22 pneumatic valves are used as switches, then in this case, a plug is turned out of the operating valve and the hose (stand-alone channel) is screwed in from the failed valve. And the plug is screwed into the place of the disconnected hose (stand-alone channel) in the inoperative air distributor, which allows you to disconnect the completely inoperative air distributor and organize the work of the second hose (stand-alone channel) screwed into the working air distributor. For all this, you only need a screwdriver, a wrench and the hands of a tractor driver.

The embodiment of the second embodiment, due to the fact that it contains a compressor whose output is connected to the main input, is faster than the first version due to the use of a significantly shorter main (which in the first version should extend from, for example, the fan to the switch, this is of order several meters). In utility model No. 112585 of 08/31/2011 and analogues, markers use hydraulic cylinders that work, including due to the pressure generated by the hydraulic pump in them, which uses the tractor’s energy resources. The time from the moment the operation is switched from, for example, the left marker to the right one consists of the fact that the left marker should rise for a certain time, and the right one should fall for a certain time. Raising and lowering the markers is carried out by hydraulic cylinders, which ultimately use the tractor’s energy resources. The execution of the second option due to the fact that it contains a compressor, the output of which is connected to the input of the line, almost instantly supplies air through the line, one of the switches to an autonomous channel, without wasting the tractor’s energy resources on raising and lowering the markers used today. In addition, it is planned to use a compressor operating on a voltage of 12 volts from the corresponding generator, which reduces energy consumption to almost zero. Thus, the above essential features of the execution of the second option and the second option itself, compared with markers and their analogs used in utility model No. 112585 dated August 31, 2011, significantly reduce energy consumption. The remaining technical results of the device of the second embodiment and its execution are similar to those in the first embodiment.

In a third embodiment, the device includes load-bearing elements, a trunk, a switch, two autonomous channels, and a compressor. Technical results are achieved due to the fact that:

- what is made in the form of two autonomous channels connected to the output of the switch, the input of which is connected to the compressor by a highway.

The technical results of the third embodiment are similar to those described in the first embodiment and the execution of the second embodiment.

The above switches may have pneumatic, mechanical, electro-pneumatic, electromagnetic and other controls.

The use of the proposed significant differences (features) in the above design options will reduce energy costs and get 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

Utility model No. 112585 dated 08/31/2011 and its analogues include so-called markers (devices for creating a footprint on the soil) having load-bearing structures on which brackets are located, in which are the axes of the disks assembly. These load-bearing structures are connected by levers to the rods of hydraulic cylinders that raise and lower the markers. A large design range of seed drills, complexes, aggregates, including seeders of utility model No. 112585 dated 08/31/2011), have similar load-bearing marker designs as the TS-M8000A seeder withstand both the efforts of powerful hydraulic cylinders and the loads from mechanical contact of disks with the soil. These factors make it necessary to have a supporting structure consisting of 64 parts in each marker of the TS-M8000A seeder. Accordingly, the two supporting structures are composed of 128 parts, which gives significant weight. Moreover, the greater the width of the seeder, the greater the weight of the supporting structures. The supporting structure of the device according to the invention can be made, for example, in the form of a light aluminum corner, on which, for example, a light plastic hose (stand-alone channel) fixed in several places with plastic locks. The options for the execution of the supporting structure may be different. In accordance with the catalog of parts and assembly units of the TS-M8000A seeder (see the coordinates of the first analogue), the right marker SN-8.57.00.00.000-01 of the seeder SN-8.00.00.000 contains 91 parts. The left marker has the same amount. Thus, both markers have more than 182 parts. Any of the proposed devices will have at least ten times fewer parts (this can be seen even from the proposed structural diagrams) and, accordingly, significantly less weight.

The device (Fig. 1) contains a highway 1, switch 2, two autonomous channels 3. Technical results are achieved due to the fact that: - the device is made in the form of two autonomous channels 3 connected to the output of switch 2, the input of which is connected to highway 1.

When the device (Fig. 1) is in working condition, for example, in a seeder (unit, complex), the second end, for example, of the hose (line 1) of the device (Fig. 1) is, for example, mounted on a fitting welded, for example, to the inside of the fan casing and is fixed on it, for example, with a clamp or other fixing element. The other end of the hose (line 1) is dressed on a fitting, also fixed by a fastening element, and the fitting is screwed into a switch 2, for which, for example, a pneumatic distributor can be used. Each working output of switch 2 (and there will be two) will be connected to a fitting on which a hose can be put on (stand-alone channel 3) and secured with a clamp or other structural element. The second ends of these hoses (autonomous channels 3) can be fixed in a rigid profile, or can be connected to the pipe. Options may be different. Switch 2 can be located both inside and outside the tractor cab. Everything will depend on the layout and design of switch 2. After preparing the equipment for work, and checking its working condition, the tractor driver starts the tractor, turns the control handle of switch 2, if it is, for example, the air distributor to the left, connecting part of the air flow, for example, a fan through the main 1, through a pneumatic distributor (switch 2) with the first autonomous channel 3. At the same time, air with a certain pressure, passing through the first autonomous channel 3, acts on the soil with its jet, leaving it on th groove. At this time, the second channel of the air distributor (switch 2) is blocked and part of the air flow from, for example, the fan through the highway 1 and the air distributor (switch 2) does not enter the second autonomous channel 3. After the tractor driver has sowed the first field strip to the end, he unfolds in order to sow the next lane adjacent to the first. At this moment, he turns the same control handle of the air distributor (switch 2) in the opposite direction, connecting the air flow with the second autonomous channel 3, while blocking the first autonomous channel 3 for air access using the same air distributor (switch 2). Due to this, part of the air flow, for example, of the fan, passing through the highway 1, the pneumatic distributor (switch 2) enters the second autonomous channel 3. At the same time, air with a certain pressure passing through the second autonomous channel 3 acts on the soil with its jet, leaving it on it groove. And then the cycle repeats. The connections of the second end of line 1 can be anywhere (depending on the design of the seeder, unit, complex and fan), it can be the output part of the fan casing, or part of the sleeve extending from the fan, or part of the pneumatic seeder system, etc.

The design of the device (Fig. 1), made in the form of two autonomous channels 3 connected to the output of the switch 2, the input of which is connected to the highway 1, works from an air source or a gaseous mixture. In the future, only air will be referred to in the text. The device (Fig. 1) is intended to form a trace on the soil by applying a pressure of an air stream to the soil passing from highway 1 through switch 2, alternately one to one autonomous channel 3, then to another autonomous channel 3 using switch 2, which provides air flow control.

The highway 1 is designed to supply air from an air pressure source to switch 2. Switch 2 is used to switch channels and supply air to one autonomous channel 3, then to another. Autonomous channels 3 are designed to provide air movement from the switch 2 to its outlet and direct it to the soil. An analysis of the above structural elements shows that any of these elements cannot work autonomously to obtain a trace on the soil. Only in the assembly and in the interconnection of structural elements is it possible to obtain the above results.

For the operation of markers of utility model No. 12525 of 08/31/2011 and other analogues, hydraulic cylinders (receiving oil pressure from the hydraulic pump through the hydraulic system and performing alternate raising and lowering of the markers), connected by levers with the supporting structure of the markers, discs assembled (located on the supporting structure of markers), a hydraulic pump, as well as a control device in the form of a hydraulic distributor. Only the presence of these devices in conjunction provide a trace on the ground.

Comparing the design of the device (Fig. 1) with the design of the markers of utility model No. 112585 of 08/31/2011 and other analogues, we conclude the following:

1. Due to the fact that the proposed device is made in the form of two autonomous channels 3 connected to the output of the switch 2, the input of which is connected to the highway 1, it does not require mechanical contact with the soil, since only air under pressure is needed on the soil to form a trace. And air is used from the “excess” power of the fan, without using the tractor’s energy resources.

In utility model No. 112585 of 08/31/2011 and other analogs, for the formation of a footprint on the soil, a mechanical contact of the marker disc with the soil is necessary, which creates high friction forces, which on the one hand increase the tractor’s energy consumption, and, on the other hand, break down due to stresses individual parts and components of markers, the restoration of which requires additional energy resources.

2. In the device (Fig. 1), air is supplied from, for example, a fan through a highway 1 connected to the input of switch 2, which switches channels and delivers air alternately to one autonomous channel 3, or to another connected to the output of switch 2. Autonomous channels 3 are located and fixed on lightweight supporting structures rigidly fixed at the time of operation, for example, on the coulter beams of the seeder and located at the required distance from them. If, for example, a manual pneumatic distributor is used as switch 2, then the tractor driver turns his handle either left or right. At the same time, additional tractor energy resources are not used to switch channels and obtain a trace on the soil.

In utility model No. 112585 dated 08/31/2011 and other analogs, for the left marker to stop working and the right marker to start working, it is necessary that the left marker hydraulic cylinder lifts the left marker vertically and the right marker hydraulic cylinder lowers the right marker down. Switching is provided by a hydrodistributor, and the oil is supplied under pressure by a hydraulic pump through a hydraulic system. In this case, the hydraulic pump uses the tractor’s energy resources. In addition, the slow operation of the valve with the hydraulic system also requires energy, which does not require switch 2, the input of which is connected to the highway 1, and the outputs with autonomous channels 3.

3. As previously noted and described, the device (Fig. 1) due to its design (made in the form of two autonomous channels 3 connected to the output of the switch 2, the input of which is connected to the highway 1), has a small weight and practically does not affect traction force of a tractor, and, therefore, does not use additional energy resources.

The weight of the markers considered by the wound on the example of the marker SN-8.57.00.00.000-01 of the seeder SN-8.00.00.000 (TS-M8000A) has a significant weight and affects the tractor's pulling force, and, therefore, uses additional energy resources. The design of the markers of the TS-M8000A seeder is similar to those used in utility model No. 112585 of 08/31/2011 and its analogues. In addition, the weight of two hydraulic cylinders with a part of the hydraulic system (metal or metal-rubber pipelines with hydraulic elements) also affects the traction of the tractor and, therefore, uses additional energy resources.

Thus, the highway 1, switch 2 and autonomous channels 3 connected structurally into a single device (Fig. 1) by their aforementioned essential features make it possible to reduce energy consumption compared to markers and other analogs used in utility model No. 112585 of 08/31/2011.

As switch 2, for example, a valve type B71-22 valve can be used (either a pneumatic valve or a valve with a different control system, etc.). The range of possible switches 2 is very wide. The control of the switch 2 may be pneumatic, mechanical, electro-pneumatic, electromagnetic and other controls.

The device (Fig. 2) consists of a line 1, two switches 2, two autonomous channels 3. The design contains a compressor 4. The technical results of the device (Fig. 2) are achieved due to the fact that:

- the device is made in the form of two autonomous channels 3 connected to the outputs of the switches 2, the inputs of which are connected to

- common highway 3;

- contains a compressor 4, the output of which is connected to the input of the highway 1 (execution).

When the device (Fig. 2) is in working condition, for example, in a seeder (unit, complex), the second end, for example, of the hose (line 1) of the device is dressed, for example, on a fitting welded, for example, to the inside of the fan housing and fixed on it, for example, with a clamp or other fastening element. The other end of the hose (line 1) is dressed on a tee, also fastened with a fastener, and switches 2 are screwed to the remaining ends of the tee, for example, a pneumatic valve of type B71-22 (either a pneumatic valve or a pneumatic valve with a different control system and etc.), hereinafter referred to as pneumatic distributor.

Each working output of the pneumatic distributor (switch 2) will be connected to the fitting, on which a hose can be put on (autonomous channel 3) and secured with a clamp or other structural element. The second ends of these hoses (autonomous channels 3) can be fixed in a rigid profile either, or can be connected to the pipe. Options may be different. Switch 2 can be located both inside and outside the tractor cab. Everything will depend on the layout and design of switch 2. After preparing the equipment for work, and checking its working condition, the tractor operator starts the tractor, turns the control handle of the first switch 2, if it is, for example, the air distributor to the left, connecting part of the air flow, for example, a fan through line 1, through a pneumatic distributor (switch 2) with the first autonomous channel 3. At the same time, air with a certain pressure, passing through the first autonomous channel 3, acts on the soil with its jet, leaving Yaya her groove. At this time, the channel of the second air distributor (switch 2) is closed and part of the air flow from, for example, the fan through the highway 1 does not enter the second autonomous channel 3. After the tractor driver has sowed the first strip of the field to the end, it unfolds in order to sow the next strip adjacent to the first. At this moment, he turns the control handle of the first air distributor (switch 2) in the opposite direction, blocking the air flow to the first independent channel 3. Then he turns the control handle of the second air distributor (switch 2) to the left, connecting the air flow from the fan through line 1, the second a pneumatic distributor (switch 2) with a second autonomous channel 3. At the same time, air passing through the second autonomous channel 3 acts on the soil with its jet, leaving boron on it Wait. And then the cycle repeats.

Today, operated mechanical markers (including those used in utility model No. 112585 dated 08/31/2011) often fail. This is the failure of the bearings with an increase in the size of the holes for the bearing, separation of the disk stop, a break in the axis of the disk and the bracket for the axis, and so on. What forces the tractor driver to leave for the not plowed part of the field for disassembling, welding, etc. in a word, to restore broken parts and assemblies, and then again return to the site of the interrupted sowing. Additional turning the tractor on and off, as well as forced idle movements associated with the repair and additionally expended energy resources for repairs (for example, welding, drilling, etc.), all this significantly increases energy costs. The device (Fig. 2) due to its design, made in the form of two autonomous channels 3 connected to the outputs of the switches 2, the inputs of which are connected to a common highway 1, does not contact the soil with autonomous channels 3 that produce grooves, and due to the fact that in the aggregate of the above signs, it works from the air, it does not require lifting and lowering the supporting structure, as well as the above repair, for which the markers of utility model No. 112585 of 08/31/2011, including significant amounts of energy, are used resources, which avoids the above energy costs associated, including with the repair of used markers. In addition, to ensure the complete absence of energy consumption for the repair of the device (Fig. 2), a second switch 2 is used, the output of which is connected to an autonomous channel 3, and the input of the second switch 2 is connected to a common highway 1. This allows in the field, without leaving repair switch 2 from the tractor. If, for example, type B71-22 pneumatic distributors are used as switches 2, then in this case, the plug is turned out of the pneumatic distributor in working condition, and screwed into its place etsya hose (autonomous channel 3) from the failed pneumatic distributor. The plug is screwed in place of the disconnected hose (stand-alone channel 3) into the inoperative air distributor, which allows you to disconnect the completely inoperative air distributor and organize the work of the second hose (stand-alone channel 3) screwed into the working air distributor (switch 2). For all this, you only need a screwdriver, a wrench and the hands of a tractor driver.

The embodiment of the second embodiment due to the fact that it contains a compressor 4, the output of which is connected to the input of the highway 1, has a higher speed compared to the first embodiment of the device (Fig. 1) due to the use of a significantly shorter highway 1 (which in the first embodiment of the device ( Fig. 1) should extend from, for example, a fan to switch 2, this is of the order of several meters). If controls with compressor 4 are located in the tractor cab.

Today, seeders (aggregates, complexes) use hydraulic cylinders to operate the markers, which work, including due to the pressure generated by the hydraulic pump in them, which uses the tractor’s energy resources. In the markers used today (including those used in the utility model No. 112585 of 08/31/2011), the time from switching from, for example, the left marker to the right one consists of the fact that the left marker should rise for a certain time, and the right one should a certain time should fall. Raising and lowering the markers is carried out by hydraulic cylinders, which ultimately use the tractor’s energy resources. The embodiment of the device (Fig. 2) due to the fact that it contains a compressor 4, the output of which is connected to the input of the highway 1, almost instantly supplies air through the highway 1, one of the switches 2 into an autonomous channel 3, without wasting the tractor’s energy resources on lifting and lowering the markers used today. In addition, it is planned to use a compressor 4 operating on a voltage of 12 volts from the corresponding generator, which reduces energy consumption to almost zero. Thus, the above significant features of the embodiment of the device (Fig. 2) and the device itself (Fig. 2) allow, compared with the markers used in the utility model No. 112585 of 08/31/2011, as well as those used in other seeders (units, complexes) to significantly reduce energy costs. The remaining technical results of the device (Fig. 2) and its execution are similar to those in the device (Fig. 1).

The device (Fig. 3) includes a highway 1, switch 2, two autonomous channels 3, compressor 4. Technical results are achieved due to the fact that:

- that the device is made in the form of two autonomous channels 3 connected to the output of the switch 2, the input of which is connected by a highway 1 to the compressor 4.

The operation of the device (Fig. 3) is similar to the operation of the device (Fig. 1), the only difference is in the sources of creating air pressure. In the device (Fig. 1) it is, for example, a fan, and in the device (Fig. 3) it is a compressor 4.

The technical results of the device (Fig. 3) are similar to those described in the device (Fig. 1) and device design (Fig. 2).
