Problems solved by technology

The above-mentioned structure and the ear picking process not only have the technical problems of high power consumption and too long corn ear stalks, but also, when the corn ear and the ear picking plate are in contact with the ear picking resistance is too large, it is easy to cause a gap between the stem puller and the corn stalk. The slipping fault caused by the phenomenon that the corn ear cannot be pulled off from the corn stalk, resulting in the loss of the corn ear and increased harvest loss

Abstract

The blade shearing type corn ear picking mechanism belongs to agricultural machinery; left and right seat plates are respectively equipped on the upper side of the frame body, above the left and right stem pulling rollers, and hinged on the opposite inner parts of the left and right seat plates. The left and right shearing blades are installed evenly, and the limit pin shafts are mated and installed on the left and right seat plates respectively. The shaft is fixedly connected with the right shearing blade, and the pressure spring is set on the limit pin shaft; It is novel, reasonable, less power consumption for ear picking, small ear stalk length, good ear quality, high ear picking rate, strong applicability and reliable operation.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a corn ear picking operation mechanism that can be assembled on a corn harvesting machine tool. Background technique [0002] The corn ear picking structure combined with the stem roller and the ear picking plate is currently the most common ear picking mechanism equipped on corn harvesting machines. It is widely used due to its simple structure, compact structure, and high operating efficiency. However, due to the fact that the stalk rollers used during operation clamp the corn stalks in the forced pull-down movement, the ears of corn are forcibly blocked by the ear picking board so that they cannot move downward together with the corn stalks. The stretching force pulls the corn ear off the corn stalk to complete the ear picking operation. The above-mentioned structure and the ear picking process not only have the technical problems of high power consumption and too long corn ear ...
