Pneumatic suspension separation device for potato harvester with vine removal device

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a pneumatic suspension separation device for a potato harvester with a vine removal device, which includes a frame, a separation device, a vibration device, a suspension device and a vine removal device. The vertical plate, the separation device, the vibration device, and the suspension device are all arranged between the two vertical plates, and the separation device and the vibration device are connected with the two vertical plates. The separation device includes two separation screens arranged side by side, and the two separation screens There is a gap between them, and the lower part of the separation screen is equipped with a vibration device and a suspension device, the suspension device is set under the gap between the two separation screens, the creep removal device is set on the upper part of the separation screen, and the tendril removal device is connected to the two The upper part of the riser. The invention improves the damage reduction and separation effect of the conveying and separating link of the potato combine harvester, and can effectively solve the problems that mechanical separation is prone to collision, entanglement and skin breakage in the current potato harvesting process, and the seedlings cannot be treated centrally.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a pneumatic suspension separation device for a potato harvester with a vine removal device. Background technique [0002] At present, potato harvesting machinery is developing in the direction of combined harvesting. Generally, after the separation of potato rocks and potato seedlings, combined with one or more stages of cleaning, the potato harvesting machinery is transported to the side of the potato collection hopper or to the potato box configured by itself. [0003] The principle of separation of potatoes and stones is: the mixture of potatoes and stones runs at a certain speed, and the inertia difference between the stones and the potatoes is separated; the separation and cleaning of potato seedlings usually use a pair of counter-rotating seedling rollers and conventional Rod separation screen to achieve. [0004] The structure of the above-mentioned separat...

AI Technical Summary

Problems solved by technology

[0004] The structure of the above-mentioned separation method is complex, the potatoes have experienced too many mechanical structures, and the potato stones collide with each other during the separation process, which easily leads to damage to the potatoes, and it is difficult to separate and clean thoroughly

[0005] In addition, the vines after the separation of the potato vines are usually directly thrown into the air. Although the harvester is equipped with a corresponding impurity blocking device, the vines may still fall back into the potatoes that have been separated from the vines, affecting the harvest quality; After the seedlings and vines are thrown into the field, it is difficult to decompose in a short time, and it will also bring inconvenience to subsequent field operations such as plowing.
