(57) Abstract:

Use: irrigation technique, namely in drive sprinkler machines to reduce power. Gear drive each control rack self-propelled trucks fitted with wings from the guide. Toothed gear drive diagonally arranged supporting racks installed offset by an angle corresponding step of the move. At the initial moment of one pair of diagonally arranged supporting shoes raised and the other lowered to the ground. When enabled, the motor-reducer rotation of the PTO transmission is transmitted through the side gears in a gear connecting rod and guide. One pair of anchor shoes resting on the ground, moves the wings on a trajectory close to a straight line, at the same time, another pair of anchor shoes moving over the earth along a curved trajectory. 2 Il.

In Fig. 1 shows a self-propelled truck, General view; Fig. 2 - the same, top view.

Operates self-propelled cart as follows. At the initial moment of diagonally spaced bearing pads 18 and 21 are raised, and 19 and 20 on the ground. When you switch the gear motor 2 located on the frame 1, the rotation is transmitted to the PTO transmission 3 through the side gears 4 and 5 gears 10 of each of the four gear-lever mechanisms 6, 7, 8 and 9. The toothed wheel 10 being in engagement with the non-driven wheels 11 and rotating in different directions, causing the connecting rod 12 with the guide 13 to move the bearing pads 18, 19, 20 and 21 with the supporting posts 14, 15, 16 and 17. The bearing shoes 19 and 20, while on the ground and move the shoes 18 and 21 move over the earth along a curved trajectory. Then reference the shoes 18 and 21 are lowered to the ground, and self-propelled truck, moving, resting on them, and bearing shoes 19 and 20 are raised above the ground, moving along a curved trajectory. Then the working process is repeated.

Self-PROPELLED TRUCK, including the support legs with the shoes and the actuator, characterized in that, to improve reliability and reduce power actuator, each leg provided with a connecting rod with the guide rail and gear kinematically connected through a gear - driven, with gears of each pair of diagonally arranged struts offset from the other pair by an angle corresponding step of the moving truck.
