Floating directional feeding type corn bionic threshing machine

Abstract

The invention relates to the field of agricultural machinery, in particular to a floating directional feeding type corn bionic threshing machine. The floating directional feeding type corn bionic threshing machine comprises a machine frame, wherein two differential rollers, a dispersing roller and a threshing roller are arranged on the machine frame; a dispersing area for destroying a corn particle integrated arrangement structure on corn ears and a threshing area for completely stripping the corn particles from the corn ears are formed between the dispersing roller and the threshing roller as well as the two differential rollers correspondingly; a feeding device which is used for conveying the corn ears to the dispersing area one by one along the axial direction between the two differential rollers is arranged on one side, provided with the dispersing area, of the machine frame; height floating adjusting devices are arranged between each of roller shafts of the dispersing roller and the threshing roller as well as the machine frame; and the height floating adjusting devices perform floating adjustment on the height of the dispersing roller and the height of the threshing roller according to the diameter difference of the corn ears which enter the dispersing area and the threshing area. The floating directional feeding type corn bionic threshing machine has the advantages of extremely low breakage rate, high threshing rate and avoidance of corncob breakage, and is suitable for subsequent processing after the corn ears are picked.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a floating and directional feeding bionic corn thresher. Background technique [0002] Corn is one of the main crops in my country and can be used as feed and industrial raw materials. It is an important economic crop and plays a vital role in the development of my country's grain production and animal husbandry. In recent years, the yield of corn has gradually increased, and people have paid more and more attention to the steps of ear picking, peeling, and threshing in corn harvesting. The corn harvester in the current market only has the functions of picking ears, peeling, and straw crushing, and the corn threshing process still needs It is done by thresher alone. [0003] At present, most of our country adopts the corn thresher designed according to the striking principle to carry out the corn threshing. High will lead to a huge waste of raw materials, affect the effect...

Problems solved by technology

[0003] At present, most of our country adopts the corn thresher designed according to the striking principle to carry out the corn threshing. High will lead to a huge waste of raw materials, affect the effect of threshing and cause large economic losses. The damage of corn kernels will also affect the short-term and long-term storage of corn. The mechanical damage in the process of corn threshing has become the main problem of corn threshing

2. The threshing gap in the corn threshing process is very important. Because the diameter and length of corn ears are different, the threshing gap is too large to lead to a low cleaning rate, and the threshing gap is too small to lead to an increase in damage rate. Corn thresher The non-automatic adjustment of the threshing gap is an important cause of mechanical damage to corn and an important factor affecting the threshing effect
