High-efficiency corn thresher

Abstract

The invention discloses an efficient corn thresher. The thresher comprises a feeding device and a material shaking device; the feeding device comprises a first shell and a feeding mechanism, and the feeding mechanism comprises a first disc, a second disc and a transition liner; the first disc is arranged at an inlet of the first shell, a first round hole is formed in the first disc, and the seconddisc is arranged at the rear end of the first shell; a second round hole is formed in the second disc, and an annular blade is arranged in the second round hole; the transition liner is arranged between the first round hole and the second round hole; the material shaking device is arranged at the rear end of a feeding tube and comprises a second shell, a mesh screen, a first vibration mechanism and a second vibration mechanism; a partition plate is arranged in the second shell and divides the second shell into an upper chamber and a lower chamber, the upper chamber is used for separating cornkernels with corncob, and the lower chamber is used for separating the corn kernels with impurities; a drying device is arranged at the bottom of the partition plate. Accordingly, threshing of multiple pieces of corn can be conducted simultaneously, and the corn threshing efficiency is improved.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a high-efficiency corn thresher. Background technique [0002] Corn is one of the most important foodstuffs in the world. About one-third of the world's population uses corn as their main food. Among them, corn accounts for 50% of the food composition of Asians, more than 90%, and 25% in Africa. , Latin America accounted for 40%. The history of corn cultivation in my country is about 470 years. However, due to its high yield, good quality and strong adaptability, the cultivated 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. Due to the large yield and the value of each part of the corn itself, the workload after picking the corn is undoubtedly huge for farmers. After picking corn in the countryside, people need to go through the process of peeling the corn, and then put it in an o...

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 put it in an open field to dry, so that the corn is dried to a certain extent before threshing the corn. Most corn threshers can only process one corn at a time. threshing, the threshing efficiency is low, and during the threshing process, the corn kernels are easy to collapse everywhere, and the labor for later cleaning is relatively large. For the entire corn threshing process, the overall efficiency is low
