Corn threshing machine capable of ensuring threshing integrity

Abstract

The invention discloses a corn threshing machine capable of ensuring threshing integrity. The corn threshing machine comprises a feeding device and a material shaking device, wherein the feeding device comprises a first shell and a feeding mechanism; the feeding mechanism comprises a first disc, a second disc and transmission cylinders; the first disc is arranged at the inlet of the first shell; first round holes are formed in the first disc; the second disc is arranged at the rear end of the first shell; second round holes are formed in the second disc; an annular blade comprising a pluralityof sub blades and an annular connecting piece is arranged in each second round hole; each transmission cylinder is arranged between one first round hole and one second round hole; the material shaking device is arranged at the rear end of a feeding cylinder; the material shaking device comprises a second shell, a mesh screen, a first vibration mechanism and a second vibration mechanism; and a partition plate is arranged in the second shell, and divides the second shell into an upper chamber and a lower chamber, wherein the upper chamber is used for separating corn kernels with corncobs, and the lower chamber is used for separating corn kernels with impurities. According to the corn threshing machine provided by the invention, the integrity of the threshed corn kernels is guaranteed whilecorn threshing is realized, and the quality of the threshed corn kernels is improved.

Description

Technical field [0001] The invention relates to agricultural machinery, in particular to a corn thresher capable of ensuring the completeness of threshing. Background technique [0002] Corn is one of the most important foods in the world. Today, about one-third of the world’s population uses corn as the main food. Among them, Asians make up 50% of the food composition, more than 90% of them, and Africa 25%. , Latin America accounts for 40%. The cultivation history of corn in my country is about 470 years. However, due to high yield, good quality and strong adaptability, the cultivation area has developed rapidly. At present, my country's sown area is about 300 million mu, second only to rice and wheat, and ranks third among food crops. Because of the large output and the value of all parts of the corn itself, the workload after corn picking is undoubtedly huge for farmers. After picking corn, people in rural areas need to go through the process of peeling the corn, and then ...

AI Technical Summary

Problems solved by technology

After picking corn in the countryside, people need to go through the process of peeling the corn, and then place it in an open field to dry, so that the corn is dried to a certain extent before threshing the corn, but the integrity of the threshed corn kernels is low. , there are many damaged corn kernels, and the overall quality of the corn kernels is not high, resulting in a decrease in the benefit of the farm harvest. It is necessary to provide a thresher that can not only thresh the corn kernels, but also prevent the corn kernels from being damaged.
