Folded parallel-connection adjustment soil removal and impurity removal device for potato harvester

Abstract

The invention belongs to the field of potato harvesters, and particularly relates to a folded parallel-connection adjustment soil removal and impurity removal device for a potato harvester. The devicecomprises a rack, multiple sets of soil removal and impurity removal units and multiple adjustment mechanisms; each set of soil removal and impurity removal unit comprises a first soil removal roller, a second soil removal roller and a flat roller which are arranged between two vertical plates (1); in each set of soil removal and impurity removal units, the first soil removal roller is located infront of the second soil removal roller, the flat roller is located behind the second soil removal roller, and the axis of the second soil removal roller is located above and behind the axis of the first soil removal roller; each first soil removal roller comprises a first soil removal shaft (3) and a first soil removal wheel (4), and each second soil removal roller comprises a second soil removal shaft (6) and a second soil removal wheel (7); each set of adjustment mechanism comprises a supporting base (11), a supporting arm (12), an adjustment plate (13) and an adjustment rod (15). The folded parallel-connection adjustment soil removal and impurity removal device for the potato harvester is high in soil removal efficiency and impurity removal effect, helps to improve the potato-soil separation efficiency and harvesting quality, and improves the adaptability of the potato harvester to different land parcels.

Description

technical field [0001] The invention belongs to the field of potato harvesters, in particular to a stacked parallel adjustment soil removal and impurity removal device for potato harvesters, which is used for removing soil, seedlings and other impurities adhering to the surface of potatoes. Background technique [0002] China is one of the countries with the largest potato planting area in the world. At the same time, China's potato consumption is growing at an average annual rate of 8%, and it is also one of the countries with the fastest growing consumption in the world. In recent years, the sowing and harvesting of the domestic potato production industry has been basically mechanized, but the surface of the harvested potatoes often sticks to a layer of soil, which is also mixed with some potato seedlings and weeds. At present, the potato harvester has a poor effect of removing soil and impurities, especially when the potato harvester is working on a field with heavy soil....

Problems solved by technology

[0004] The purpose of the present invention is to provide a method that can overcome the problems of the existing potato harvesting machinery, such as the single conveying mode, affecting the separation efficiency and harvesting quality, realize the removal of soil and impurities in the potato harvesting process, and can be adjusted in time according to the differences in planting plots, etc. Separation parameters are conducive to improving the effect of soil removal and impurity removal in the potato harvesting process, improving the overall separation efficiency and ensuring better harvest quality, and avoiding poor soil removal performance of the harvester due to the "slanted flat conveying" pole structure of the existing equipment. Poor, impurity removal effect needs to be improved, a wide range of applications, simple and reasonable structure, reliable operation stacked parallel adjustment soil removal and impurity removal device for potato harvesters
