Vertical axial flow drum

Abstract

The invention discloses a longitudinal axial flow drum, which belongs to the technical field of combine harvester threshing and separation devices, and comprises a drum body, a drum front shaft, a power input shaft, a drum front bracket and a drum rear bracket, and the drum body includes a feeding part and a drum The body, the anti-winding element is provided between the front support of the roller and the feeding part, and the anti-winding element includes: a material guide crescent and a wedge-shaped roller front cover fixed on the front support of the roller, and the material guide crescent includes Disc and material guide plate, one end of the disc is fixedly installed on the front support of the drum, and the other end has an opening; the disc passes through the installation hole of the front cover of the drum; it is fixed on the front of the drum The front cover cover of the drum on the cover; the front protrusion of the drum fixed on the front end face of the feeding part, and the front protrusion of the drum is located in the opening. During the harvesting operation, the front axle of the drum is not easy to entangle the grass, and the working efficiency is high, which realizes the simultaneous harvesting of various crops, and does not need to replace the drum, which meets the user's profit demand.

Description

technical field [0001] The invention belongs to the technical field of combine harvester threshing and separation devices, and in particular relates to a longitudinal axial flow drum. Background technique [0002] In the Central Plains region of China, crop planting conditions are: rotation of wheat and corn, rotation of wheat and soybean, rotation of wheat and rice. Users generally hope that the combine harvester basically does not need to replace parts or replace a few easily replaceable parts such as concave plates. Only by adjusting the speed of the drum can it not only harvest wheat, but also harvest soybeans, rice, corn and other crops. However, the current mainstream combine harvesters are difficult to achieve the above functions, and the harvesting effect is not ideal, which is mainly manifested in high crushing rate, large entrainment loss and low work efficiency. [0003] On the other hand, users have higher and higher requirements for the return on investment of ...

AI Technical Summary

Problems solved by technology

If rice, corn, soybeans and other crops are harvested, not only the front axle of the drum is easy to get entangled with grass, but also the harvesting effect is not good.

[0007] Since the existing combine harvester needs to frequently replace the special drum when harvesting multiple crops, it has disadvantages such as high labor intensity, low production efficiency, and high cost of use.
