Pneumatic suspension separating device of potato harvester with vine removing device

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a pneumatic suspension separating device of a potato harvester with a vine removing device, which comprises a frame, a separating device, a vibration device, a suspension device and a vine removing device, wherein the frame comprises two parallel plates, the separating device, the vibration device and the suspension device are arranged between the two vertical plates; the separation device and the vibration device are connected with the two vertical plates; the separation device comprises two separation screens arranged side by side; a gap is formed between the two separation screens; the lower part of the separation screen is respectively provided with the vibration device and the suspension device; the suspension device is arranged below the gap between the two separation screens, the vine removing device is arranged at the upper part of the separation screen, and the vine removing device is connected with the upper parts of the two vertical plates. By means of the device, the loss reduction and separation effect of the conveying and separation link of a potato combine harvester is improved,and the problems that the mechanical separation in the prior potato harvesting process is easy to generate collision, high in winding and peeling rate, and the seedling grass can not be treated intensively can be effectively solved.

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.
