Description

Sectional adjustable diameter-variable threshing cylinder shaft roller

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a sectional adjustable variable-diameter threshing cylinder shaft roller matched with a threshing cylinder assembly.

Background

The traditional threshing cylinder comprises a threaded rod type threshing cylinder, a spike-tooth type threshing cylinder and an arch-tooth type threshing cylinder, which can not realize the adjustment and the change of the diameter of the cylinder, namely the diameter of the cylinder is fixed and unchanged. In the actual threshing operation, because the diameter of the roller can not be changed, the threshing space between the roller and the threshing concave plate is fixed, when the yield of the threshed grains is different or the feeding amount is different, the threshing quality is influenced, and the threshing quality comprises the operation indexes such as threshing rate, seed breakage rate and the like. When the crop yield is low or the feeding amount is small, the operation efficiency of the machine is reduced, and the threshing operation cost is increased; when the crop yield is high or the feeding amount is large, the threshing rate and the kernel recovery rate are reduced, the kernel breakage rate is improved, and the kernel loss is caused.

In order to solve the above problems, the applicant has studied a diameter-adjustable threshing cylinder, but since the threshing cylinder cannot be adjusted separately in sections and the diameter of the shaft roller of the whole threshing cylinder is always consistent, the adaptability to the axial-flow feeding threshing cylinder with a long axial size and the radial tangential-flow feeding threshing cylinder with a large width is poor, the diameter of the shaft roller of the threshing cylinder cannot be adjusted in sections according to the working conditions, and the adaptability is extremely required to be improved.
