Multi-separation pneumatic suspension impurity removal device of potato harvester

Abstract

The invention provides a multi-separation pneumatic suspension impurity removal device of a potato harvester, which is characterized by comprising a separation frame, a layered separation device, a seedling lateral throwing device and a suspension impurity removal device, and the suspension impurity removal device comprises a rubbing impurity removal device, a potato seedling output device, a conveying device and a pneumatic impurity removal device. The cross section of a blowing body of a blowing opening of a pneumatic impurity removing device of the suspension impurity removing device is 6-shaped, an opening is formed in the tail end of the 6-shaped blowing body of an empty shell, an air inlet is formed in one end, in the length direction, of a circular ring part of the 6-shaped blowing body, and a plurality of arc-shaped flow guide plates are arranged in the blowing body in the length direction of the blowing body. And a plurality of air uniformizing plates are arranged at an opening at the tail end of the '6' of the blowing body along the length direction of the blowing body. The multi-separation effect is guaranteed, meanwhile, the potato damage rate, the peel breaking rate and the impurity rate in the potato harvesting process are reduced, and the optimal separation effect and harvesting quality are guaranteed.

Description

technical field [0001] The invention provides a multi-separation pneumatic suspension impurity removal device for a potato harvester, which belongs to the field of potato harvesting equipment and is mainly used for the potato harvester to realize potato-soil-impurity separation in the harvesting process, and to remove the potato mixed in the potato-soil mixture. Seedlings and weeds as well as stones and high-moisture sticky soil, and remove soil adhering to the potato skin. Background technique [0002] The impurity removal device is the key working part of the potato harvester. For potato harvesting operations, the effect of removing impurities is one of the main factors affecting the rate of bright potato, damaged potato, broken skin and loss rate of potato harvesting. How to achieve efficient separation of potato seedlings, weeds and stones in potato soil mixture It is the key technology for the research and development of high-end potato harvesting equipment to remove t...

AI Technical Summary

Problems solved by technology

It is often difficult to efficiently remove potato seedlings and weeds in the potato-soil mixture and soil adhering to the potato skin by using conventional vibrating separation sieve type, lifting chain type, and rotating cage separation type potato harvester, resulting in subsequent separation. The finished potatoes contain too many seedlings and weeds, and even some soil on the potato surface belt, which greatly increases the burden of subsequent manual picking and bagging, and also increases the potato damage rate, skin breakage rate and loss rate of the potato harvest. a series of serious problems
