Longitudinal-axial-flow roller

Abstract

The invention discloses a longitudinal-axial-flow roller, and belongs to the technical field of combine harvester threshing separating devices. The longitudinal-axial-flow roller comprises a roller body, a roller front shaft, a power input shaft, a roller front support and a roller rear support. The roller body comprises a feeding-in part and a roller body part, and an anti-tangling element is arranged between the roller front support and the feeding-in part and comprises a guiding crescent moon, a wedge-shaped roller front cover, a roller front cover seal cover and roller front protrusions wherein the guiding crescent moon and the wedge-shaped roller front cover are fixed to the roller front support, the guiding crescent moon comprises a disc and a guiding plate, one end of the disc is fixedly installed on the roller front support, and an opening is formed in the other end of the disc. The disc penetrates through an installing hole in the roller front cover, the roller front cover seal cover is fixed to the roller front cover, and the roller front protrusions are fixed to the front end face of the feeding-in part and located inside the opening. In harvesting, the roller front shaft is not likely to be tangled with weeds, working efficiency is high, kinds of crops are harvested without replacing the roller, and the requirements for earnings of a user are met.

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.
