Problems solved by technology

After adopting the above-mentioned drum form, the material is conveyed mainly through the grass guide plate on the upper cover of the drum from entering to discharging from the threshing chamber, which results in too many rotation cycles of the material in the drum chamber and too long residence time in the drum chamber. Long, easy to cause blockage, affect the working efficiency of the drum, and at the same time affect the cleaning efficiency due to excessive prolapse

Embodiment Construction

[0013] As shown in the accompanying drawings, an axial flow drum for a combine harvester includes a drum shaft 1, a drum body fixed on the drum shaft 1, and the drum body includes a cylindrical body portion 7 and a truncated cone The cylindrical feeding end 4; the feeding screw blade 3 fixed on the surface of the conical frustum of the feeding end is used to grab the material and then feed the material into the drum chamber. The feeding screw blade 3 consists of two pieces The short helical blades form a double-headed helical structure, which can speed up the feeding speed and reduce the possibility of material clogging; the conveying helical blades 6 fixed on the cylindrical surface of the cylinder body are used to realize the conveying of materials in the drum chamber. Guide, the conveying helical blade 7 is composed of a single-headed helical blade.

[0014] The threshing and separating teeth 5 are fixedly connected to the outer peripheral portion of the conveying screw bla...

Abstract

The present invention discloses an axial-flow roller that is used for the combined harvester, which comprises a roller axle and a roller body that is fixed on the roller axle, wherein, the roller body comprises a cylindrical body, a coniform feeding end, a feeding helical blade that is fixed on the cylindrical surface of the feeding end and a conveying helical blade that is fixed on the cylindrical surface of the cylindrical body. The axial-flow roller can realize the clean threshing and thorough separation, thereby effectively reducing the blockage, having high efficiency and greatly reducing the negative influences on the riddling system caused by the excessive threshed grain and separated objects.

Description

technical field [0001] The invention relates to the technical field of combine harvester threshing devices, in particular to an axial flow drum. Background technique [0002] Most combine harvesters use axial-flow drums for threshing and separation, and most of the axial-flow drums use plate drums, rod-toothed drums, and grained rod drums. After adopting the above-mentioned drum form, the material is conveyed mainly through the grass guide plate on the upper cover of the drum from entering to discharging from the threshing chamber, which results in too many rotation cycles of the material in the drum chamber and too long residence time in the drum chamber. Long, it is easy to cause blockage, which affects the working efficiency of the drum, and at the same time, the cleaning efficiency is affected by too much protruding matter. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an axial flow drum for combine harves...
