Corn thresher

Abstract

The invention discloses a raw food material processing machine, in particular to a corn thresher which comprises a roller, a material placing plate and a bran discharge plate. The material placing plate and the bran discharge plate are arranged on two sides of the roller, material baffles are arranged on lateral sides of the material placing plate and the bran discharge plate far away from the roller, and a screen matched with corns in grain size dimensions is arranged on the material placing plate. Three spike tooth areas are arranged on the roller, and each spike tooth area is an annular groove formed in the surface of the roller. Spike teeth are arranged in the three spike tooth areas which are arrayed in the axial direction of the roller, the spike tooth area in the middle is a short-teeth spike tooth area, and the spike tooth areas on two sides are a long-teeth spike tooth area. The length of the spike teeth in the short-teeth spike tooth area is 2-5cm longer than those in the long-teeth spike tooth area. The corn thresher overcomes the defects of the prior art of single gap control and insufficient grain threshing; has two corn threshing gaps so the middle portions and two ends of the corns can be threshed simultaneously.

Description

technical field [0001] The invention relates to a processing machine for food raw materials, in particular to a corn earing machine. Background technique [0002] Most of the natural foods that are directly picked need to undergo certain processing before they can be used as raw materials for industrialized foods, and corn is one of them. Modern industry has adopted the corresponding industry to peel off the wrapping leaves on the surface of corn. The technical requirements of each equipment for the corn earing device are mainly: clean removal, broken grains, and as little dark damage as possible; good separation performance, which is The special requirements put forward by the development of the combine harvester in the direction of large productivity, good versatility, adaptable to various markings and various conditions, low power consumption, and in some cases, it is required to keep the stems intact or reduce the breakage as much as possible.

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned prior art can realize the separation of corn kernels and corn cobs, the width of the corn itself is inconsistent, for example, the width of the middle part of the corn is larger than that of the two ends, and the above-mentioned prior art can only be separated according to one width. It is impossible to adjust different gaps in one job for corn ear control (that is, to adjust the gap between the roller and the spiral guide plate), so there will still be a lot of corn at the two ends of the finally discharged corn cobs (corn cobs). grain
