Threshing device for corn harvesting

Abstract

The invention relates to a threshing device for corn harvesting. The threshing device comprises a screening and dust removal module, a corn threshing module and a power mechanism. The screening and dust removal module is fixedly connected with the corn threshing module; the power mechanism is arranged between the screening and dust removal module and the corn threshing module in a penetrating mode; and one side of the power mechanism is slidably connected with the interior of the screening and dust removal module, and the other side of the power mechanism is fixedly connected with the corn threshing module. According to the threshing device for corn harvesting, corn is gradually threshed in a linear friction and rotation mode, so that corn threshing efficiency is improved, and damage to corn kernels in the corn threshing process is reduced; dust, impurities and the corn can be automatically separated in the corn threshing process, so that the dust and impurities are prevented from remaining on the corn kernels, and subsequent tedious work for impurity removal is omitted; and lifting exchange can be continuously carried out in the operation process, so that blockage is reduced.

Description

【Technical field】 [0001] The invention relates to the field of technical agricultural equipment, in particular to a threshing device for harvesting corn. 【Background technique】 [0002] At present, with the development of science and technology, the corn industry belt is also gradually increasing, and the corn yield is also greatly increased. However, the threshing of corn has gradually become an urgent problem to be solved. Most of the existing corn threshers adopt the drum type. High-speed rotation separates corncobs from corn kernels. However, this separation method has low production efficiency, long threshing time, long production time, and high power consumption. It cannot realize the meticulous work of corn threshing, low operating efficiency, and low safety factor. , It is not easy to maintain and repair, the heavy workload is easy to cause blockage and affect the use, not only the corn kernels are damaged, but also the corncobs are easily broken, and dust and impuri...

Problems solved by technology

[0002] At present, with the development of science and technology, the corn industry belt is also gradually increasing, and the corn yield is also greatly increased. However, the threshing of corn has gradually become an urgent problem to be solved. Most of the existing corn threshers adopt the drum type. High-speed rotation separates corncobs from corn kernels. However, this separation method has low production efficiency, long threshing time, long production time, and high power consumption. It cannot realize the meticulous work of corn threshing, low operating efficiency, and low safety factor. , It is not easy to maintain and repair, the heavy workload is easy to cause blockage and affect the use, not only the corn kernels are damaged, but also the corncobs are easily broken, and dust and impurities exist at the same time as the corn kernels, and dust removal is required later. The tedious work such as screening impurities has been done, but there is currently no corn thresher on the market that can separate corn kernels from dust and impurities at one time while protecting the corn kernels as much as possible.
