Description

The invention relates to a device for treating root crops before planting, and more particularly to devices for cutting seed potatoes in the field.

P. Invention Increased Productivity and Quality of the Suction Material.

FIG. I shows a device for cutting s.men1P) 1.x potato tubers, a section along the axis of one of the grooves of the swing conveyor; in fig. 2 is a section A-A in FIG. one; in fig. 3 - device with strings, made in the form of infinite closed contours, covering irivodic, tension and free pulleys.

The device for cutting potato seed tubers (Fig. 1) contains a hopper 1 with a belt feeder 2, a swinging multi-grooved conveyor 3 with horizontal axis 4 and an inclined 5 meter, frame 6 with strings 7 fixed to it. conveyor 8 for collecting cut tubers. Slots 10 are made in the grooves 9 of the inclined section 5 of the channel 5 of the conveyor 3, through which the node ocTpi rM of the angle of ° C to the plane of the nest of the E1 section 5 is the lead of the strings 7. butt movement along the axis of the strings of the nodes by the action of a rod 12 connected to an eccentric mounted on the high-speed shaft of the multiplier 13 driven by an electric motor (not indicated).

The pumping conveyor 3 pods on the swinging suspensions 14 with the ability to drive HiarynoM 15 from the low speed of the shaft of the multiplier 13, for its reciprocating post movement.

It is possible to make a jet in the form of infinite closed 1) 1x contours 16 (Fig. 3), covering the HJKHBBI 17 cross sections, rigidly attached to P1 1 on the high speed shaft of the multiplier 13, tension 18 and bypass 19 pins. At the same time, the cutting branches of the strings 20 are passed through the cutters 10 in the grooves 9 of the inclined section 5 of the conveyor 3.

The device for cutting potato seed tubers works in the following way.

Seed tubers of potatoes, subject to cutting, are fed to bunker 1, for example, by an unloading conveyor of a potato-sorting and item. With a tape thread 2, the tubers are fed to the horizontal section 4 of the conveyor belt 3. In this area, the tubers not only move progressively, but due to the vibration of the conveyor 3 (with a frequency of 20-25 Hz and a horizontal component of amplitude 20-25 mm), rolls 9, the orientation is large in diameter along the axes of the gutters, since, with such an orientation, the centers of mass of the tubers are the lowest level. Then, the tubers, oriented along the axes of the gutters, along the inclined section 5 of the conveyor 3 arrive at the cutting strings 7 and are cut by the strings along two segments. At the same time, on each of the lobules, the presence of g.tazks is ensured. A rather high cutting speed (about 20 m / s) is provided by a high frequency of reciprocating movement of the strings (250 Hz with an amplitude of 0.015 m). Next, the cut potato tubers are nodal but inclined section 5 of the conveyor 3 into the collecting conveyor 8.

When the strings are made in the form of endless HEJX closed loops moving in the manner indicated in FIG. 2 by an arrow in the direction, a sufficient cutting speed is ensured by a high speed of movement of the cutting contours (about 20 m / s).
