The invention relates to agriculture, namely to electrified agrotechnical systems.

The purpose of the invention is the expansion of operational capabilities.

FIG. 1 shows a diagram of the proposed system, top view; in fig. 2 - the same, front view; in fig. 3 shows an embodiment of a carriage and a wiring diagram for a power electric motor; in fig. 4 is a schematic view of the fastening of the carriage to the lintel, side view; in fig. 5 - the same, top view; in fig. 6 — front view current collector; in fig. 7 - the same, top view; in fig. 8 - rotary contact device; in fig. 9 - current-carrying rings.

On the plot of the field there are supports 1 and 2 interconnected in pairs by conductive bridges 4 mounted on insulators 3 (Fig. 1). At least two jumpers, for example, supports 1 - 1 and 2—2 are connected to the current source using conductor 5 (Fig. 2). The current source can be located in the hangar 6 for storing equipment (Fig. 1).

On the bridges 4 are suspended mobile carriages 7 carrying the conductor 8 connected via a current collector 9 and cable 10 to an electrically driven mobile unit (tractor) 11, for example, a tractor with a machining tool 12. The carriage 7 consists of a base 13 on which profiled rollers 14 and a wheel are located 15 friction associated with the gear 16 and the worm shaft 17 with the electric drive 18. Through the friction wheel 15, the brush 19 is connected by conductor 20 to the current-carrying bus 21 of the conductor 8 attached to the base 13 of the carriage 7 with a lug 22. Current-carrying tire 23 p Connected to all electric drives 18 carriages 7 and is a minus. Current-carrying bus 24 is also common to all the carriages 7 and is designed to control their electric drives 18 using the switch K.1 · The control of the power electric drive (M) 25 is carried out using a rheostat (Fig. 3). Traction 26 provides additional fastening of the conductor 8 to the carriage 7. Moving the carriage 7 along jumper 4 can be provided with the help of a gear drum 27, and the jumper 4 itself can be made in the form of a metal punched tape 28 pushed against the drum 27 by a roller 29. Current collector 9 ( Fig. 6) is made in the form of the base 30, on which the guide smooth rollers 31 and the rollers 32 with shoulders are mounted. Using rollers 31 and 32, the current collector 9 is moved along a conductor 8. To increase the mechanical strength in the body of the conductor 8, elements 33 of metal reinforcement are located. Contact brushes 34 interact with current-carrying tires 31, 23 and 24, which are connected via cable 10 to a control system of an electrically driven mobile unit 11. With current collector 9, cable 10 is pivotally connected by means of a lug 35 and a rod 36. To ensure autonomous movement, the current collector 9 can be provided with an electromechanical drive with a toothed drum 37 (by analogy with a movable carriage 7), and the base of the conductor 8 is made in the form of punched tape 37 (Fig. 7). The connection of the brushes 34 with the cable 10 can be made through a rotary contact device made in the form of current-carrying rings 38 installed on the base, interacting with the current-collecting brushes 39 located on the rotary platform 40 to which the conductors 41 of the cable 10 are connected.

The system works as follows.

The electrically driven mobile unit (tractor) G1 with the processing tool 12 receives, via jumpers 4, carriages 7, an electrical conductor 8, a current collector 9 and a cable 10, electrical energy from the current source, moves along the conductor 8 and processes the field. Reaching the opposite edge of the field, the tractor 1 ί turns and moves in the opposite direction. The cable 10 can also perform the role of a towing current collector 9. With a significant sagging of the conductor 8, it is advisable to use an electrically driven construction of the current collector 9 (FIG. 7) synchronously moving along the conductor 8 together with the moving tractor 11. The cable 10 allows the tractor 11 to carry out as it moves. maneuver to the side (within the cable length). When expanding the 'Processing strip by contact K1 (Fig. 3), feeding "4-" to the current-carrying bus 24, turn on the electric drives 18 of all the carriages 7 (Fig. 1), which move the conductors 8 to the required distance in one direction or another (indicated by the dotted line ).
