Description

In the well-known jumper of the plow furrows, the turntable is turned off due to the resistance forces to the displaced soil in front of the turntable blade. The disadvantage of such a jumper trimmer is that it is suitable for working only on a pre-plowed field, and does not ensure the integrity of the longitudinal shafts, forming ruptures, which leads to partial leakage of spring water and erosion of the soil on the slopes.

A distinctive feature of the proposed jumper dividers is that the rotor blades are made across the width of the groove to be laid with the ends smoothly bent in the direction of movement of the unit, and a ratchet with a four rectangular teeth is used for periodic turns of the rotor for 90 ° counterclockwise mi located in the same plane with the blades, the automatic activation of which is dried, is removed from the support wheel with the pusher through the hinged arm This wheel is a rocker with two elbows, and a lever with an adjustable tension spring attached to the axle of the stop leg.

The drawing shows a jumper maker in two projections.

The plow groove maker is mounted behind a single-body mounted plow with a support wheel. It consists of a frame 1 rigidly attached to the plow body, turntables 2 with four blades, dividing the width equal to the width of the furrow laid by the plow, and bent downwards in the direction of movement of the unit, shaft 5 on which the top 2 is rigidly fixed, and ratchet 4 seconds four rectangular teeth located in the same plane with the blades of the turntables 2. On the side of the ratchet 4 on the frame is fixed a stop bolt 5, to the axis of which is attached a pivoting lever 6 with a tension spring 7. The pivoting lever has 8 him with a rocker 9 scrapped pivotally suspended on a rack 10 // plow support wheel 2 -№ kor№ 117026- 117026

pusa A pusher 12 is attached to the wheel rim //, which interacts with the beam 9 at each revolution of the wheel. As a result of the swing of the rocker arm 9, the turntable 2 is turned on and off.

When the plow is put into operation, one of the blades of the turntable, having a vertical position, removes the soil, shuffled, and leaves it in front of it until the turntable turns off. As soon as the rocker disengages from the pusher, the pivot arm under the action of the spring takes up its original position and resists the shaft, the tree released from the engagement, rests again on the next ratchet tooth, stopping the rotation of the turntable after the next blade is put into operation. Thus, the furrows are laid at a distance of 1 to 4 from one another, and the jumpers in them are formed after 1-3 m, and have a height not less than the depth of the furrow.

Subject invention

The bridge is made by plowing furrows using a rotating four-blade turntable mounted as the main tool mounted on a frame rigidly attached to the rear of a single body hinged plow with a support wheel, characterized in that, in order to cut the ground layer from the bottom of the furrow to be laid and periodically load it to form durable water retaining bridges, located at equal distance from each other, the blades of the vane are made with smoothly curved in the direction of movement of the unit ends, and for periodically turning the turntable 90 ° counterclockwise and sequentially putting its blades into operation, a ratchet with four rectangular teeth in the same plane as the blades was used, which was automatically activated from the support wheel with the pusher through the hinge hanging on the rack This wheel is a rocker with two elbows and a lever with an adjustable tension spring attached to the axis of the stop latch.
