Corn threshing and screening device

Abstract

The invention relates to the field of corn threshing and screening devices, in particular to a corn threshing and screening device which comprises a body, a threshing mechanism, an opening and closingmechanism, a screening mechanism, a conveying mechanism and a power mechanism. By arranging the threshing mechanism, traditional manual threshing operation is avoided, the time-saving and labor-saving effects are achieved, and the threshing efficiency is improved; by arranging the opening and closing mechanism, the opening and closing angle of a sealing cover can be conveniently adjusted at will,and therefore the interior of the body can be conveniently overhauled, and the later fault processing steps of the body are simplified; by means of the arrangement of the screening mechanism, corn kernels of different sizes can be screened conveniently, so that the economic value of corns is improved; the corn kernels are conveniently and rapidly conveyed to the top end of the screening mechanismthrough the conveying mechanism, so that screening work of the screening mechanism is assisted; and power is conveniently provided for the threshing mechanism and the conveying mechanism at the sametime through the power mechanism, so thatsimultaneous operation of the threshing mechanism and the conveying mechanism is facilitated, moreover, the arrangement of a plurality of redundant power is reduced, and the utilization rate of the internal space of the body is improved.

Description

technical field [0001] The invention relates to the field of corn threshing and screening devices, in particular to a corn threshing and screening device. Background technique [0002] Corn is an annual herbaceous plant of the Poaceae family. Also known as corn corn, corn sticks, corn, pearl rice, etc. Native to Central and South America, it is an important food crop in the world and is widely distributed in the United States, China, Brazil and other countries. Compared with traditional grain crops such as rice and wheat, corn has strong drought tolerance, cold tolerance, barren tolerance and excellent environmental adaptability. Corn has high nutritional value and is an excellent food crop. As a high-yield grain crop in China, corn is an important source of feed for animal husbandry, aquaculture, and aquaculture, and is also one of the indispensable raw materials for food, medical and health, light industry, and chemical industry. Because corn resources are extremely ri...

Problems solved by technology

[0003] Mature corn needs to be threshed and stored when it is collected and stored. However, most traditional corn threshers simply perform threshing operations. Since the market has different prices for corn kernels of different sizes, the corn kernels of different sizes are mixed together. It lowers the overall economic value, thereby reducing the grower's economic harvest of crops
