Pulling platform for heading vegetable

Abstract

The invention provides a pulling platform for heading vegetable, belonging to agricultural machinery. According to the invention, a root-part guide-in arc-shaped fork group is arranged at the front end part of the middle of a platform frame and in front parts of a right pulling screw shaft and a left pulling screw shaft; a left righting guide-in twisting plate and a right righting guide-in twisting plate are symmetrically arranged on the left side part and the right side part of the front end of the platform frame, located at the front parts of the left outer sides of the left pulling screw shaft and the root-part guide-in arc-shaped fork group and located at the front parts of the right outer sides of the right pulling screw shaft and the root-part guide-in arc-shaped fork group respectively; and a plurality of rollers are rotatably assembled on the opposite inner wall surfaces of the left righting guide-in twisting plate and the right righting guide-in twisting plate respectively. The pulling platform provided by the invention is reasonable and simple in structure, low in manufacturing cost, wide in vegetable guide-in range, high in adaptability, accurate and smooth in guide-in,small in guide-in operation resistance, low in power consumption, low in missing pull rate and damage rate and reliable in use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a lifting operation assembly on a vegetable harvesting machine. Background technique [0002] At present, the mechanized harvesting operation of head vegetables mostly adopts the pull-out method that the root system of head vegetables is pulled out from the soil by the cooperation of the left and right helical shafts that are relatively configured, and the harvest is completed. During operation, in order to accurately guide the vegetables on the same row into the area between the left and right screw shafts for pulling up, the existing table for pulling up vegetables with corrugated belts may be equipped. The introduction mechanism, or the introduction mechanism equipped with double helical rollers in a conical configuration, not only has the defects of complex structure, high manufacturing cost, and large power consumption, especially because of its narrow introduction range, it is...

Problems solved by technology

During operation, in order to accurately guide the vegetables on the same row into the area between the left and right screw shafts for pulling up, the existing table for pulling up vegetables with corrugated belts may be equipped. The introduction mechanism, or the introduction mechanism equipped with double helical rollers in a conical configuration, not only has the defects of complex structure, high manufacturing cost, and large power consumption, especially because of its narrow introduction range, it is very easy to miss pulling and damage vegetables. problems, causing losses
