Abstract

The invention provides a threshing roller with an adjustable threshing diameter and a combine harvester. The threshing roller with the adjustable threshing diameter comprises the threshing roller, diameter adjusting devices, transmission devices and self-locking devices, wherein the diameter adjusting devices are located at the inner sides of supporting plates arranged at two ends of the threshingroller; the self-locking devices are located at the tail parts of the threshing roller; the transmission devices transmit power to the diameter adjusting devices and the self-locking devices; stepless adjustment of a roller threshing diameter can be realized through the diameter adjusting devices; meanwhile, the self-locking devices can completely lock an adjusted roller diameter to guarantee thestability of roller operation. According to the invention, the roller threshing diameter of the combine harvester can be conveniently and quickly adjusted, so the threshing linear speed and threshingclearance of the threshing roller can meet the optimal harvesting parameters of different varieties of grains at different regions, and the threshing adaptability of the combine harvester can be effectively improved.

Description

technical field

[0001] The invention relates to the technical field of a grain threshing and separating device on a combine harvester, in particular to a threshing cylinder with adjustable threshing diameter. Background technique

[0002] The threshing drum is an important part of the combined harvesting machine. During the working process, it cooperates with the concave screen to separate the grain from the stem. Among them, the linear speed of the threshing element and the threshing gap of the threshing drum have a great influence on the grain threshing quality. In the actual harvest process, due to different varieties, different moisture contents, and different maturity degrees in the same area, the connection force between the grain and the grain stalk is uniform. Therefore, the threshing effect produced by a single threshing element line speed and threshing gap of the threshing drum is not ideal, and changing the threshing diameter of the drum can effectively change the...
