Corn threshing device

Abstract

The invention relates to a corn threshing device, and belongs to the technical field of agriculture product processing. The corn threshing device is high in threshing efficiency and low in labor intensity and is not prone to hand injury; freezing drying is carried out through liquid nitrogen, the corn water content is reduced, and preservation of nutritional ingredients of corn is facilitated; inaddition, in the freezing drying process, moisture in corn kernels is frozen and expanded, contact points of the corn kernels and corn cobs are loosened accordingly, and threshing can be better carried out; a negative-pressure air fan is used, impurities of the corn kernels after threshing are greatly reduced, and the production rate of the whole device is wholly increased; meanwhile, the line speed of the outer edge and the diameter of a plate tooth rolling cylinder and the inner diameter of a threshing cabin are strictly controlled, the complete degree of the corn kernels during threshing isguaranteed, the whole kernel rate after final threshing is 98% or above accordingly, the separation rate is 99% or above, and the corn threshing device has broad application prospects.

Description

technical field [0001] The invention relates to a corn threshing device, which belongs to the technical field of agricultural product processing. Background technique [0002] Corn is a crop with a high yield in China's agricultural products. It is rich in nutrients and suitable for dry land planting. It is an important food crop and economic crop in my country. In addition, corn is also used as an important feed and industrial raw material. Livestock development plays a vital role. For the threshing of corn after harvest, traditional manual threshing is still mostly used in small rural planting areas in my country. Usually, two corn cobs are rubbed together, or a screwdriver is used for threshing, or a single corn cob is threshed by a simple hand-operated machine. , not only the labor intensity is high, but also the efficiency is low, and it is easy to hurt hands, which seriously restricts the production efficiency of corn. The corn threshers currently on the market general...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: for most of the traditional manual threshing at present, usually two corn cobs are rubbed together, or a screwdriver is used for threshing, or a single hand-operated simple machine is used for threshing a single corn cob, which is not only labor-intensive It is large, has low efficiency, and is easy to hurt hands, which seriously restricts the production efficiency of corn. However, the corn threshers that appear on the market generally have corn cobs smashed and mixed, and the threshing is not clean and contains many impurities. Re-cleaning increases the operating procedures, is time-consuming and labor-intensive, and is not conducive to farmers' defects in the sale of corn on the market. A corn threshing device is provided
