Problems solved by technology

However, field experiments have found that if conventional soil removal devices are used to remove soil and impurities, the potato pieces will be concentrated in the process of collecting potatoes, with serious collisions, and the rate of potato damage and skin breakage cannot meet the normal harvesting requirements. , resulting in large harvest losses

Abstract

The invention provides a longitudinal non-equidistant soil removal and damage reduction device for a potato harvester. Each end has a circular cross-section shaft section, and the lengths of the circular section shaft sections at both ends are different. The outer circle of the impurity removal wheel with a rectangular hole in the center evenly protrudes a plurality of impurity removal fingers, and each impurity removal finger is located perpendicular to In the same plane of the impurity removal wheel axis and inclined towards the same circumferential direction, multiple impurity removal wheels are set on the middle rectangular section of the impurity removal major axis through the central rectangular hole, and the two ends of the impurity removal short axis are rectangular in cross section Each has a circular cross-section shaft section extending out, and the lengths of the circular cross-section shaft sections at both ends are different. A plurality of impurity removal wheels are set on the middle rectangular section of the impurity removal short shaft through the central rectangular hole. The invention can realize soil clearing and miscellaneous damage reduction control, and has good damage reduction effect and high working reliability.

Description

technical field [0001] The invention provides a longitudinal non-equidistant soil removal and damage reduction device for a potato harvester, which is mainly used for damage reduction and damage prevention of a potato combine harvester. Background technique [0002] Potato segment harvester technology is relatively mature, and intelligent potato combine harvester has gradually become the key equipment for large-scale mechanization. For the potato-soil mixture screened by the separating sieve after excavation, it is the key to the performance of the potato combine harvester to complete the soil removal operation with high efficiency and low loss. Using a conventional cleaning device, the cleaned potatoes fall to the potato collection conveyor belt and are distributed more concentratedly. In the case of high-efficiency harvesting operations, the thickness of the material layer often causes the potatoes to interact with each other during the potato collection process. Squeeze ...
