Corn threshing device with classified screening function

Abstract

The invention discloses a corn threshing device with a classified screening function. The corn threshing device with the classified screening function comprises a bottom plate, a lifting mechanism, athreshing mechanism and a screening mechanism, wherein the lifting mechanism is arranged above the bottom plate; the threshing mechanism is arranged on the left of the lifting mechanism and composed of a feeding hopper, a threshing cavity, a first rotating shaft, a second rotating shaft, a ratch, helical blades, a driven gear A, a driving gear, a driven gear B, a third rotating shaft, dischargingholes and a moving door; the screening mechanism is arranged under the threshing mechanism and composed of a connecting rod, a screening plate, a support rod, a guide plate, a first collecting tank, asecond collecting tank, a third collecting tank, a fourth collecting tank and a screening cavity. The corn threshing device with the classified screening function is good and thorough in threshing effects and capable of sorting corn kernels with different diameters and facilitating classified application.

Description

technical field [0001] The invention relates to a threshing device, in particular to a corn threshing device with the function of grading and screening. Background technique [0002] The history of corn cultivation in my country is about 470 years. At present, my country's sown area is about 300 million mu, second only to rice and wheat, ranking third among food crops, and second only to the United States in the world. It is widely planted in tropical and temperate regions of the world and is an important cereal. Corn tastes sweet and can be used in various dishes, such as corn braised, corn juice, etc. It is also the main raw material for industrial alcohol and shochu. [0003] With the development of science and technology, the corn industry belt is also gradually increasing, and the corn yield is also greatly increased, and the threshing of corn has gradually become an urgent problem to be solved. The existing corn threshing mainly adopts the manual threshing method, bu...

Problems solved by technology

[0003] With the development of science and technology, the corn industry belt is also gradually increasing, and the corn yield is also greatly increased, and the threshing of corn has gradually become an urgent problem to be solved. The existing corn threshing mainly adopts the manual threshing method, but this The method is not only labor-intensive, but also inefficient

Most of the corn threshers on the market now have low production efficiency and relatively high labor intensity. They cannot realize the meticulous work of corn threshing, fail to achieve the expected effect, and the threshing is not complete, resulting in waste. At the same time, due to the different growth patterns of corn cobs , resulting in different sizes of corn kernels, the existing corn thresher did not sort the small corn kernels in time, which reduced the overall quality of corn
