Description

(®4) B.Shmelev plow

The casing 5 of the plow has a right-turning 7 and left-turning 8 left-handed surfaces, pillars 9, 10 and frame 11. In the rear part of the casing there are dumps 12 made of elastic bands or rods.

At the front of the plow, there is an asterisk 13, loosely mounted on the transmission shaft 14, which is rotated from the tractor's PTO shaft. The asterisk 13 | iepe3 spring 15 is connected to the sleeve 16 fixed on the shaft 14. Thanks to this fastening, the blades 2, during operation, make elastic, smooth movements relative to the axis of the screw 1, the axes of the screws installed in the front and rear bearings 17 and 18 fixed in racks 19 frames

| 1lug works as follows.

When moving plow cutting knives; 4 production of m-three vertical cuts | gochva, forming the walls of the furrows and the side faces / layers, plowshare dumping | the surfaces cut the soil in the central one of the horizontal plane, forming the DNW; furrows and lower graniplasts, simultaneously conical tops of augers; 1 crashes into the stern surface of the layers and, rotating, pulls the layers into the casings. The unequal height of the screw blades 2 screws 1 and chat & shape of the cutting edges of the blades facilitate cutting the sod and transporting soil inside the casing. The passage through the casing channel 20 turns to the bottom with its backdrops. . its boro-zdy. When meeting with insurmountable obstacles, a safety clutch is triggered in the drive mechanism, augers 1. Screws can be

as an active working body with a drive. from the tractor's PTO and passive, driven in rotation from the reactive forces of the soil during the forward movement of the plow.

Sticking and plugging of the screws 1 is prevented by the fact that the blades 2 vibrate during operation due to uneven resistance. the soil and the presence of springs 15, and also because the blades 2 of one screw 1 enter the spaces between the blades of the other and clean each other.

Claims (2)
