Threshing rib

Abstract

The present invention discloses a threshing rib. The threshing rib comprises a rack and a first threshing chamber, wherein the first threshing chamber is arranged on the rack in a mode that the first threshing chamber is lower in the back part and higher in the front part; brake wheels and an engine adjusting device are arranged on the bottom of the rack; and the engine adjusting device comprises a first cross bar and a second cross bar, wherein the first cross bar and the second cross bar are parallel to each other, and first cross bar adjustment holes and second cross bar adjustment holes are correspondingly formed in the length direction of the first cross bar and the second cross bar. The threshing rib disclosed by the invention has the advantages that the corn removal rate is improved; the corn kernels are prevented from being destroyed in the threshing process; the service life of a drive belt is prolonged while the safety performance is improved. The threshing rib has the beneficial effects of low modification cost, high threshing velocity and the like.

Description

technical field [0001] The invention relates to a threshing cylinder, in particular to a threshing rib on the threshing cylinder. Background technique [0002] The existing corn thresher comprises a threshing drum, a threshing bin and a frame, and the drum of the corn thresher is installed in the threshing bin and can rotate relative to the threshing bin. In order to improve the threshing efficiency, the drum of the existing threshing machine is generally provided with threshing ribs, and when the drum rotates, the corn kernels are separated from the corn cob under the action of the threshing ribs. However, there is still a low threshing rate, and usually a second threshing is required to thresh all the corn kernels on the corn cob, which affects the threshing efficiency. On the other hand, the power unit installed on the thresher cannot be adjusted. So that there are limitations; on the one hand, when the corn kernels fall from the threshing bin, because the corn kernels a...

Problems solved by technology

However, there is still a low threshing rate, and usually a second threshing is required to thresh all the corn kernels on the corn cob, which affects the threshing efficiency. On the other hand, the power unit installed on the thresher cannot be adjusted. So that there are limitations; on the one hand, when the corn kernels fall from the threshing bin, because the corn kernels are hit by the high-speed operation of the threshing drum, the corn kernels cannot fall into the collected container, and the operator needs to remove the corn on the ground. The granules are picked up in the collection container, which increases the labor intensity of the operator and reduces the threshing efficiency

While the corn cob is running at high speed, the corn cob is easily stuck between the threshing drum and the threshing bin, causing the thresher to be stuck
