SU1635927A1 - Tuber feeder of planting mechanism of multi-row potato planter - Google Patents

Abstract

The invention relates to agricultural machine building, multi-breeding potato planters. The purpose of the invention is to improve the accuracy of planting. The invention relates to agricultural machine-building, in particular to multi-breeding potato planters. The purpose of the invention is to improve the accuracy of planting tubers by reducing pulsed shock loads on the planting machine. Figure 1 shows the proposed device, top view; Fig. 2 shows the cut A of tubers by reducing pulsed shock loads on the landing gear. The tuber feeder contains a stationary bottom 1 with combs, a working bunker 3 with shutters-agitators 4 interacting with cam 5 mounted on the shaft, return springs 6 and agitators 7 Each cam 5 on the shaft is turned in one direction relative to the previous one by angle 2 l p k, where p - the number of cams on the shaft; k - the number of working protrusions on one cam. When the shaft rotates with the agitators 7 and the cams 5, the lower ends of the flaps 4 are lifted periodically, the tubers in the hopper 3 are set in motion. The rotation of adjacent cams is provided by alternately raising and lowering the leaf-agitators, which reduces the shock impulse loads on the landing gear. 4 il. And in Fig 1; Fig 3 - section B - B in Fig.1; fig 4 - section b - b in fig.Z. The device for feeding the tubers to the planting machines of the two-row potato planter contains a fixed bottom 1 with combs 2, a working bunker 3 with shutters-agitators 4. One end of the valve-agitators 4 are hinged to the bunker 3, and the other interact with the cams 5. Under the doors of the interlocking 4 CO with o CJ JV O VI VI

Description

return springs 6 are installed. Cams 5 are attached to the agitator 7 and rigidly mounted on the shaft 8 with it. Each agitator 7 with cams 5 is installed opposite the corresponding sash-hatch of the caster 4. Each cam on the shaft is turned in one direction relative to the previous one at an angle of 2 liters (nk) 1, where n is the number of cams on the shaft; k - the number of working projections on one cam

The device works as follows.

The rotation of the drive sprocket, fixedly mounted on the bottom of the landing gear, is transmitted via a chain transmission (not shown) to inline R with agitators 7 and cams 5. When rotating 8 in 8 agitators 7, the cams 5 located on the shaft raise the lower end of the hinge valves. 1, thereby driving the tubers in the bunker 3, When lowering the sash-slips 4 springs 6 layers of tubers PG; I eat chips in the direction of the agitators 7, when simultaneously forming the formed CE od :, potatoes in the bunker 3.

The agitator valves 4, which remove pulsed shock loads on the landing gear and drive. Therefore, the uniformity of rotation of the landing gear increases, which contributes to a more intensive destruction of the resulting arches.

The use of the invention improves the uniformity of rotation of the planting machines and the accuracy of planting potato tubers by 5-7%, reduces the number of twos and gaps by i -2%, and also reduces the noise level
