Description

FIG. one

The invention relates to the field of agricultural machinery and is intended for use in mechanized harvesting of root and tuber crops. The purpose of the invention is to increase the purity of the roots in the roll by laying it outside the zone of soil separation.

FIG. 1 shows a schematic view of the root crop of the crop, side view; in fig. 2 - the same, top view.

The rake of the roots of the club includes successively located copying her 1 and digging her 2 devices, separating the bar conveyor

3, over the working surface of which are located narrowing 4 and separations 5

augers. The middle part of the reversible unloading conveyor 6 is located under the gathering area of the separated root crops from the separating screw 5, and its longitudinal axis is angled to the longitudinal axis of the swath former in such a way that one end of the reversing unloading conveyor 6 is above the roll laying side of the machine and the other - above the place of laying the roll after the machine, directly behind the zone of emission of impurities from under the separating screw b. A transfer device 7 is installed above the section of the reversing discharge conveyor 6 adjacent to the rear end of the separating screw 5, which prevents the reversing discharge conveyor from being hit by soil impurities from under the separating screw 5.

The swath of the root crop works as follows.

When a copying machine 1 is moving, device 1, for example copying wheels or track rollers, a copy of the relief of the pile, provides a predetermined depth of digging devices 2 that direct the undermined mass onto the bar conveyor 3. That part of the tuberiferous mass that goes to the narrowing auger

4, changes the direction of its movement and enters the zone of the beginning of displacement of the product to be cleaned with a separating screw.

5. The rest of the heap, which passed by the narrowing auger 4, is also brought to the same zone.

Pass along the separating jaw 5, the separated roots or tubers are directed to the middle part of the reversing discharge conveyor 6.

When laying the roll on the first pass, following the mashina, the reversing discharge conveyor 6 drops the tubers into the roll (Fig. 2A) after the ejection zone (Fig. 2 V) of the separated soil impurities (Fig. 2 D).

Soil impurities, emanated from under the separating screw 5 in the zone above the reversing conveyor 6, fall on the transfer device 7, which sends them further, beyond the limits of the roll formed (Fig. 2 .Л).

When laying the tubers in the swath, which is located on the side (Fig. 2B) of the machine (the second and third passes of the swath former), the reverse reloading conveyor belt 6 receives the opposite direction of movement.
