Abstract

The invention relates to an adjustable threshing cylinder upper hood which comprises a shell, at least two fixed spiral flow deflectors and at least two pairs of adjustable spiral flow deflectors. Each pair of adjustable spiral flow deflectors comprises a left adjustable spiral flow deflector and a right adjustable spiral flow deflector which are oppositely arranged; the adjustable threshing cylinder upper hood also comprises a sliding pin linkage rod, sliding pins, a connection hinge plate, flow deflector regulating rods, a flow deflector regulation and control rod, a flow deflector regulating linkage rod, hinge pins and locking blocks. In the invention, the angles of the left adjustable spiral flow deflectors and the right adjustable spiral flow deflectors can be regulated according to the types and the humidity conditions of harvested crops and the angular positions of the flow deflectors can be locked, so that the harvesting effect achieves the best state and firmness of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adjustable upper cover of a threshing cylinder. Background technique [0002] At present, in existing axial-flow combine harvesters or threshers, the spiral deflectors in the upper cover of their threshing drums are all fixed, and the angle cannot be changed. In the case of humidity, the threshing and separation effect is good. When the angle of the spiral deflector is small, when threshing and drying crops, the number of rotations in the threshing drum is small, the threshing and separation time is short, and the grains can be separated cleanly, so the locomotive has a small operating load and a large feeding amount; when threshing wet crops , the crops in the threshing drum will be threshed and separated, and the angle should be increased at this time, so that the crops rotate more times in the threshing drum, so that the grains can be fully threshed and sepa...
