A high-efficiency and low-loss corn threshing combined operation machine

Abstract

The invention relates to a high-efficiency and low-loss corn threshing combined operation machine, which belongs to the technical field of agricultural machinery. The machine includes a peeling mechanism, a broken core mechanism and a threshing mechanism; one end of an inclined pressing plate is hinged on the lower surface of the upper cover plate of the upper cover assembly of the peeling mechanism, and a compression spring is installed between the inclined pressing plate and the upper cover plate; The peeling roller assembly, the peeling roller assembly contains a pair of helical rollers, and the outer upper part of the two helical rollers is equipped with adjacent peeling rollers respectively, and the peeling roller has a surface concave-convex structure that involves the bract leaves when rotating; The bract channel of the air inlet of the fan; the output end of the peeling mechanism is connected with the input end of the broken core mechanism through the conveying groove, and the broken core mechanism is connected with the threshing mechanism located below it. After adopting the basic technical scheme of the present invention, the peeling, core breaking and threshing of corn ears with bract leaves, especially high-humidity corn ears, can be automatically completed at one time, thereby greatly improving the operation efficiency of corn ear picking and reducing threshing damage.

Description

technical field [0001] The invention relates to a corn threshing device, in particular to a high-efficiency and low-loss corn threshing combined operation machine with the function of peeling and breaking cores, belonging to the technical field of agricultural machinery. Background technique [0002] Corn has multiple uses such as food, feed, industrial processing, and edible oil, and is widely planted. However, due to the tight stubble and the high moisture content of corn ears during the harvest period, most corn in China uses ear picking, peeling, and boxing. , transportation, drying, and threshing segmental harvesting mode, there are many operation links and high cost, and the dehydration process of corn ears and grains is limited by the weather and the site. If the drying and threshing cannot be done in time, mildew, rot, and germination will easily occur And so on, reducing the yield and quality. According to the technical conditions of corn harvesting machinery GB / T ...

AI Technical Summary

Problems solved by technology

Although the corn segmental combine harvester has its own peeling mechanism, it still cannot solve the dilemma of high-humidity corn direct threshing damage. It needs subsequent measures such as drying and drying in the field before threshing operations. The increased follow-up operation process is not only wasteful Manpower and material resources, and greatly affected by the weather

In addition, the above-mentioned prior art also has the disadvantage that the effective broken core rate is not high, so multiple threshing treatments are required, and the corn kernels are still more damaged.
