Abstract

The invention relates to agricultural machinery, in particular to machines for harvesting potatoes. The purpose of the invention is to reduce the labor costs for the selection of tubers by eliminating their planting with tops and plant residues. The potato digger contains fasteners 1 fixed on the frame 6, main 2 and cascade 3 separating elevators, running wheels 4 and single-bar grating 5. Grate 5 is installed so that its upper end is fixed on frame 6 above and away from the end of the cascade elevator 3, and lower the ends of its rods are directed under the cascade elevator 3 against the progress of the technological process beyond the end of the cascade elevator 3. In the process of operation, the heap is fed to the grate 5. The potato tubers spill between the rods of the grate 5, as The OP between its bars exceeds the gap between the bars of the sheets of the separating elevators. The plant and plant residues slide along the bars of grid 5 down and forward along the digger. Thus, the tubers are stacked on top of the plant residues, which excludes their sprinkling and subsequent selection of tubers in connection with this requires less labor. 1 h. item f-ly, 2 ill. (L

The invention relates to agricultural machinery engineering, in particular to potato harvesting machines.

The aim of the invention is to reduce the labor costs for the selection of tubers by eliminating their planting with tops and plant residues.

FIG. 1 shows a schematic side view of a potato digger; in fig. 2 is a view A of FIG. one.

The potato digger contains podcasting blades 1, main 2 and cascade 3 separating, elevators, travel wheels 4, a device for installing and maintaining the required depth of digging blades (not shown) and a single-bar grid 5 behind the cascade elevator 3 5 exceeds the gap between the rods of canvases of separating grain elevators for passage of potato tubers through the grid. The grid 5 is installed so that its upper end is fixed on the frame 6 above and away from the end of the elevator, and the lower ends of its bars are directed under the cascade elevator 3 against the progress of the technological process beyond the end of the cascade elevator 3.

When the potato digger is undermined by the plowshares 1, the layer is destroyed and sifted at the separating elevators 2 and 3. The remaining pile is fed to the rare-bar grid 5, while the tops and plant residues are held up with rods, slide along them down and forward along the digger, and the potatoes wake up between the bars of the grid 5 and fall to the surface of the floor behind the diggers on their tops and plant residues that fell in front of them.

Thus, the tops and plant residues are laid on the floor of a separate tuber stream earlier than the tubers are laid on the same surface, which eliminates the sprinkling of the tubers, the subsequent selection of which requires less labor.

Claims (2)

1. A potato digger containing frame-mounted dropping blades, main and cascade separating elevators, travel wheels, a device for installing and maintaining the necessary depth of the digging blades and picking bar behind the cascade elevator, characterized in that, in order to reduce labor costs in picking, by eliminating their powdering with tops and plant residues, the grate is installed so that its upper end is fixed on the frame above and with distance from the end of the elevator, and the lower ends its bars are oriented at an elevator cascade upstream movement of the process beyond the end of the cascade of the elevator, the gap between the lattice rods exceeds the gap between the bars of the separating webs elevators. 2. A potato digger according to claim 1, characterized in that the grating is made oscillating. Vida
