SU124737A1 - Potato harvester for two potato harvesters - Google Patents

Description

The potato harvester for two-phase harvesting of potatoes is known, however, the use of self-contained sections of the working parts for each notok makes the harvester cumbersome and bulky.

This device offers the combination of two methods, two-flow and single-flow, of which the first is used only at the initial stage of harvesting technology, which makes it possible to simplify and simplify the design of the combine.

The drawing shows a diagram of the operation of the combine.

When the machine is in operation, the reel / grabs the tops and leads it to the pulling cage of m 2. The reel rails, lowering over the aisles, cover the tops of the potato bushes from two sides, and as the bar raises, they close and lift the dead tops. The movement of the reel rails is carried out by a copying device sliding along guide tracks 3.

Simultaneously with the capture of the tops of the topping streams, the nests of the tubers are undermined by vibrating plowshares 4 having a trough-like shape. As a result of vibration, the bond between soil particles is broken and the tubers are easily removed from the formation. The plant with the tubers remaining on it rises up with a pulling chain to vibrating pickers of 5 tubers. The chain-lifting chain is an endless rubber band attached to a chain stretched on asterisks 6, 7 and 8. When the bush hits the vibratory pickups, the stolons break and the tubers fall onto cattle board 9, from which the second elevator 10 goes. the chain is carried further, transmitted to the cross conveyor AND, and dropped to the side.

The layer of soil and the tubers torn off at the moment of pulling are taken from the vibrating plowshare to the first elevator 12, where they start, 124737

Soil screening. When moving along the elevator, the mass is supplied to the vibrating troughs 13, the frequency and amplitude of oscillations of which should be regulated within: a frequency of 500-1000 Hz, an amplitude of 15-50 mm. Vibration occurs perpendicular to the direction of mass movement along the elevator. To prevent damage to the tubers, the tine teeth are rubber-coated. From the first elevator, the mass enters the second elevator, where the process of separating the soil from the tubers continues. From the second elevator, the mass is fed to the slide 14, on which the separation of plant residues takes place. Waste is discharged onto sloped pit 15, and from there to the ground. The separation of plant residues is assisted by a stream of air from the fan 16. From the roller coaster, tubers and soil residues are fed to the vibrating plate 17, where the separation of the soil ends, and the tubers are transferred to the discharge conveyor 18 and enter the container.

Subject invention

Claims (3)

1. A potato-harvesting combine for two-stream harvesting of potatoes, characterized in that, in order to simplify the design (reduce the elevators and conveyors), it uses cumulatively known working bodies, the first harvesting stream being carried out by the vibrating ploughshare of the Elevator, and the second stream - a treadmill and a tuber digger, after which, by means of a pitched board, the severed tubers from the second stream are sent to one common flow, carried out by a scraper conveyor, slide, fan, vibrating screen m and a loading conveyor. 2. A combine according to claim 1, characterized in that, in order to reach and lift the tops, the reel with movable (interlocking) slats is used in it. 3. A combine according to claim 1, characterized in that, in order to destroy soil lumps and improve separation, it employs vibrating troughs located above the working branch of the first elevator.
