FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to bridge units for agricultural work.

The purpose of the invention is to increase the productivity of the agro-bridge during cleaning operations.

FIG. Figure 1 shows an agro-bridge with two technological sections along the edges and two carriages shown in extreme positions, front view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one ; in fig. 4 - the same, top view; in fig. 5 is a section BB in FIG. 1 (with the inscribed contour of one of the working carriages); in fig. 6 is a view of B in FIG. 3; FIG. 7 is a section on the HGD of FIG. 3; in fig. 8 is the same, an example of a possible modification; in fig. 9 is a diagram of an agro-bridge with three technological sections, top view.

Agro-bridge for harvesting, for example, root crops, has technological sections 1, to which trailers 2 are attached to one or both sides along the agro-bridge by accumulative-dosing bunkers 3 placed in one or more rows along the volume of trailers. On the outer walls of the trailers 2, inclined conveyors 4 are fixed. On top of the bunkers 3, horizontal conveyors 5 are fixed with reversible and movable along them dumping plates 6 and rotary distribution plates 7. Resetting plates 6 are fixed on wheels 8 moving along rail tracks 9 s using a cable 10, supported by rollers 11, one of which, being driven, is fastened with a reversible electric motor 12. Rotary distributor flaps 7 are fixed on shafts 13. They are loaded with counterweights 14, steering wheel The main wheel 15 and the reversible electric motor 16, by means of which the ends of the switchboard are transferred from one longitudinal yoke 17 to another. The inclined conveyors 4 have ejection flaps 18 and trays 19 that direct the products to the moving belts of the conveyors 5. The accumulation and metering hoppers 3 have unloading doors 20 with latches 21 and counterweights 22. Rubber weights 23 are mounted on the counterweights, softening blows to the counterweights on the outer wall of the bins, and a cable with handles 24 allowing the doors 20 to be closed after unloading products from the corresponding bunker. Signal lights 25 and handles 26 are fixed on the outer walls of the bins to the cables 27 connecting the handles with tabs of self-closing latches.

21. (Supporting rollers that support the cables 27 are not listed). On the inner sides of the doors 20 fixed elastic pads 28, softening blows falling on them root crops. The same pads have corresponding locations of the walls and auxiliary plates 29 of storage bins. The trailers 2 are supported on the wheel supports 30 driven by a gearmotor 31 via cardans 32.

The part of the agro-bridge, which removes products from the agro-area, consists of multi-support composite truss 33 on self-driving wheels 30. along which, using a cable drive (not indicated) and power plants installed in the volumes of 34 technological sections 1 of the agro-bridge, lead each other the carriages 35 moving along the guides 36 with interchangeable agricultural harvesting tools: a device 37 for cutting the tops of the haulm and a device 38 for removing the root crops from the ground, which through inclined conveyors 39, flax conveyors 40, dumping flaps 41, trays 42 supply products to the inputs of inclined conveyors 4

The example of making a part of the device of FIG. 8 differs from the same part of the device of FIG. 7 by increasing the number of rows of accumulative dosing bins to four, with a corresponding increase in the number of similar parts having the same digitization. the case of the latches with solenoids; the discharge doors 20 are closed by electric motors 43, on the shaft of which pulleys with toothed ratchets are attached, an inclined tray 44 is added, two fixed on equaling flap 45, overhanging elastic curtains 46, reducing the speed of movement of root crops inside the bins 3, flaps 47 with push buttons for catching latches and start buttons for electric motors 43. Devices 49 are mounted on wheel supports 30 moving along plates 48, recessed yarns of rigid multi-track gauge for clearing the threads of the track from the soil carried on them by Digit 50 in FIG. 8 denotes the vertical axis. around which you can rotate the bottom flap 18 and translate it into a vertical plane.

The device works as follows.

In the stationary state of the agro-bridge, over the transverse rows of plants, carriages 35 begin to move towards each other with interchangeable

agricultural tools 37 and 39, cutting the tops and extracting the roots, which through inclined conveyors 39, longitudinal conveyors 40, flaps 41 and trays 42 arrive at the inputs of conveyors 4, and then with the help of flaps 18, trays 19 - onto a conveyor, onto shields 6 and 7 and in the bunkers 3. In this case, the roots come in one trailer, and the tops in the other.

After the completion of one rut across the agrogod without lifting the tools 37 and 38, which is possible due to the fact that the threads of the supporting multi-track gauge are recessed below the level of the plowing layer, the tools 37 and 38 are raised, the carriages 35 begin an accelerated return to the initial state, and the agro bridge moves to an adjacent working position, stops, and the entire working cycle is repeated again.

The bunkers are loaded under the control of operators sitting in the upper lanterns of the process sections 1, from where the position of the movable plates 6, the plates 7 and the level of production received in the bins 3, which the operator controls the buttons in his lamp, are well observed changes the position of the flaps 6 and 7: loading, for example, the left row of bunkers, the operator turns on the electric motor 1b, moves the flap 7 to the other side and, using a reversing electric motor .12 moving the flap 6, fills the right row of bunkers. The operator notes the filled bunkers by turning on the signal lights 25. The drivers of trucks and motor trains carry out the unloading of the bunkers: putting the vehicle under the loaded bunker marked by the signal light, the driver pulls the handle 26 or presses the corresponding button on the flap 47, opening the outer door 20, and after emptying the bunker, it closes the door with the help of the handle 24 or presses the button on the shield 47, thereby closing the door with the help of the electric motor 43. On the shaft of the electric motor 43 is fixed t with ratchet wheel. The pulley winds up the corresponding cable until the latch 21 snaps and the motor is stopped by a limit switch. (The ratchet dog does not prevent opening the door 20).

When using the device of FIG. 8, the operator first fills, for example, two right-handed rows of bunkers, and then using known means (electric motor or cable system not shown in the drawing) translates the lower flap 18 into a vertical plane, turning it around

axis 50, and using the top flap 18 through the tray 44 fills the two left-hand rows of bins.

In order to accumulate non-breaking by-products, such as tops, off-standard roots for livestock feed, trailers with one row of bins (not shown) are used, which differ from the devices of FIG. 7 by the absence of a longitudinal partition, a shield 7 and the presence of two latches on each of the adjacent doors 20, which snap onto the brackets fixed on the partitions between the bunkers and fitted with solenoids, with which

5, all four latches open at once.

The extended multi-support agro-bridge may include several technological sections 1 (figure 2). Depending on the installed mode of the longitudinal conveyors

0 40 and the position of the flaps 41 removed from the agro-carbon production may accumulate in the bunkers located in all process sections.

The positive effect of the device is as follows. The agro-bridge has capacious accumulative devices, which significantly improves the performance of cleaning work, while: faster and easier loading

0 serving vehicles with optimally dosed quantity of products; the downtime of the agro-bridge is reduced due to the irregularity of the service transport approach; a separate accumulation of the main and auxiliary products was ensured; the device can use trailers of the same type, interchangeable, having a coupling device at both ends; if there are corresponding replaceable modules attached to the platforms (carriages) 35, the agro-bridge can also be used for the comfort of other crops, for example, grain crops, with passing straw harvesting, in passing, into bales or

5 briquettes: grain accumulates in bins of the type of figs 7 and 8, and bales or briquettes accumulate in trailers with one row of bunkers. When placing the bunkers in one row and, assuming that each trailer with the removed supports and the removed side conveyor must fit on the standard domestic iron platforms, the internal width is rounded to four meters, which allows accumulation of briquettes in such bunkers and bales of straw, as well as their unloading without jamming through the wide lower double-wing hatch, while the longitudinal conveyors 40 under the composite multi-support truss 33, in order to increase the possible width of the conveyors, are arranged in pairs, one above each them; Argomost has the ability to perform unloading work at the same time on a broad front, it can immediately load two autotractor trains that came up simultaneously in a train for main and related products or several cars at the same time; the independence of the work of the operator loading the bins and the drivers loading the transport bodies independently is ensured, which increases the productivity and quality of their work, significantly reduces the possibility of unloading the contents of the bins between the bodies of vehicles.
