Threshing roller with rotatable toothed bar

Abstract

The invention relates to a threshing roller with a rotatable toothed bar. The threshing roller comprises an amplification disc and a planetary gear train, wherein the planetary gear train comprises a planetary gear frame, a plurality of planetary gears and a central gearwheel; the inner side of the planetary gear frame is meshed with the planetary gears; each planetary gear is meshed with the central gearwheel; the central gearwheel is in key connection with a main shaft; the other end of the main shaft is in key connection with the amplification disc; each planetary gear is in key connection with a toothed bar shaft; the other end of each toothed bar shaft is fixedly arranged on the amplification disc through a bearing; a plurality of nail teeth are arranged on each toothed bar shaft. The threshing roller has the remarkable characteristics that the crop adaptability is high, blockage can be effectively prevented, the threshing rate of crops is improved, the size of a threshing device can be effectively reduced under the condition of the same feed quantity, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of grain combine harvester threshing drums, in particular to a combine harvester threshing drum with a rotatable rack. Background technique [0002] For combine harvesters such as rice combine harvesters, the threshing drum is its core component. It determines the threshing quality and production efficiency of the machine to a large extent. At present, the threshing drum is mainly divided into tangential flow drum and axial flow drum. These two drums They all rotate as a whole with the rotation of the main shaft of the drum. In this case, the threshing distance of the tangential flow drum is short and cannot meet the requirements of complete threshing. Although the separation distance of the longitudinal axial flow is long enough, it also increases the combined harvester. The size of the model, these circumstances not only make the overall appearance of the produced combine harvester not delicate enough but ...

[0002] For combine harvesters such as rice combine harvesters, the threshing drum is its core component. It determines the threshing quality and production efficiency of the machine to a large extent. At present, the threshing drum is mainly divided into tangential flow drum and axial flow drum. These two drums They all rotate as a whole with the rotation of the main shaft of the drum. In this case, the threshing distance of the tangential flow drum is short and cannot meet the requirements of complete threshing. Although the separation distance of the longitudinal axial flow is long enough, it also increases the combined harvester. In these cases, not only the overall appearance of the produced combine harvester is not refined enough, but also the production cost of the combine harvester increases.
