Description
Technical Field
The utility model relates to a device for threshing in agricultural production, in particular to a full-feeding multifunctional high-efficiency threshing machine.
Background
Rice is one of important food crops for human, and the history of cultivation and eating is quite long. Rice is consumed by half of the world's population, mainly in asia, southern europe and tropical america and parts of africa. China is the world with the longest history of rice cultivation, and rice has been grown in the world as early as six to seven thousand years ago.
With the development of society, the harvesting mode of rice is also changing continuously, and the rice is harvested and threshed by the initial manual work, semi-automatic harvesting and threshing at the later stage, and then the rice is harvested and threshed by the current full-automatic energy. The threshing mechanism of rice is also changing continuously and is more and more efficient. The threshing machine can be divided into a half-feeding threshing machine and a full-feeding threshing machine, and the difference between the two threshing machines is that the full-feeding threshing machine feeds crop stalks and ears into a threshing device for threshing; the semi-feeding is only fed into the ear part, and the stalks are exposed out of the machine along with the clamping and conveying device. Obviously, the full-feed thresher has higher requirements on straw impurities and is easier to block. The prior full-feeding thresher in the market mainly comprises a bracket, a threshing barrel, a threshing cylinder, a feeding port, a straw discharging port, a screen, a diesel engine, a threshing nail and other parts, but the following problems which are difficult to solve are easy to occur, and the straw is easy to block in the threshing barrel so as to extinguish the diesel engine; the rice is not filtered completely, so that the rice is wasted, or a large amount of dust and rice straws are easy to appear on the collected rice; in addition, the screen mesh on the threshing machine on the market at present is welded and fixed in the threshing barrel, is not easy to replace, has single function and can only be used for threshing rice.
Therefore, how to design a full-feeding multifunctional high-efficiency threshing machine can ensure that the straws in the threshing barrel are not knotted and can quickly run to the straw outlet, thereby avoiding the blockage of the straws in the threshing barrel and avoiding the phenomenon that the straws are not filtered cleanly or rice is wasted. And the screen can be conveniently replaced, thereby being used for threshing different crops. Thereby improve production efficiency, more flexibility avoids operating personnel to be injured. Meanwhile, the power machine works stably and saves energy. Is a problem to be solved in the industry.
