Novel vertical corn thresher

Abstract

The invention discloses a novel vertical corn thresher which comprises a machine body. The bottom end of the outer side of the machine body is sleeved with a fixed frame, a plurality of supporting legs are evenly arranged on the fixed frame, and the machine body is internally provided with a main threshing cavity and four auxiliary threshing cavities. Threshing rollers are arranged in the four auxiliary threshing cavities and connected with machine body through rotating shafts, the top ends of the rotating shafts are protruded out of the machine body and fixedly connected with driven wheels, a motor is arranged on one side of the machine body, a motor shaft of the motor is fixedly connected with a driving wheel, and the driving wheel is connected with all the driven wheels through a belt. Screening boxes are fixedly connected between all the supporting legs through connecting rods, and vibrators are arranged at the top ends of the screening boxes in a bilateral symmetry mode. The four threshing rollers are all positioned around the main threshing cavity, two groups of spiral threshing teeth and reminding threshing teeth jointly interact, so that cob threshing efficiency is greatly improved, the threshing cycle is reduced, and device operation efficiency is improved. The four threshing rollers act jointly, loads on the threshing rollers are reduced, and the service life of the novel vertical corn thresher is prolonged.

Description

technical field [0001] The invention relates to the field of corn threshing equipment, in particular to a novel vertical corn threshing machine. Background technique [0002] Although the existing agricultural corn threshers are of many kinds, most of them have only one threshing roller, and the threshing effect is very unsatisfactory, the threshing efficiency is low, and the corn cob is also broken into pieces by adopting the mode of feeding and threshing one by one. [0003] For this reason Chinese patent 201020113956X discloses a kind of corn thresher. The corn thresher includes a frame, a number of threshing rollers, a screen, an outer cover, etc. There are a number of threshing rollers installed on the frame. The threshing rollers are parallel to each other and located on a plane. Below the threshing roller, the outer cover is buckled on the screen to form a threshing roller. The threshing roller is located inside the threshing roller. There is a feeding port on the ou...

Problems solved by technology

[0004] However, the operation efficiency of this invention is low, a corn cob needs to be operated many times to completely remove the corn kernels, the work cycle is long, and the work cost is high; and when multiple corn cobs are threshing at the same time in the equipment, it is easy to cause the equipment to run overloaded , reduce the practical life of the equipment, increase the frequency of equipment maintenance, and the equipment investment is relatively high
