Wheat-threshing and cornstalk-cutting machine

Abstract

The invention relates to a grain-threshing and stalk-cutting machine in agricultural machinery, specifically to a wheat-threshing and cornstalk-cutting machine. A conventional wheat-threshing machine can only smash and thresh sundried wheat and has the disadvantages of single function, complex and cumbersome structure, and largely-required power. The wheat-threshing and cornstalk-cutting machine provided by the invention comprises a frame, and a feeding table, a smashing-threshing cabin, a vibration screen mechanism, an air exhausting mechanism and a packing auger conveyer which are arranged on the frame, wherein the feeding table is arranged in the front and upper part of the smashing-threshing cabin; the lower part of the smashing-threshing cabin is provided wtih the vibration screen mechanism; the air exhausting mechanism is arranged above the rear half part of the vibration screen mechanism and at the left side of the smashing-threshing cabin; and the rear part of the smashing-threshing cabin is provided with the packing auger conveyer. The wheat-threshing and cornstalk-cutting machine provided by the invention has the advantages of compact structure, light weight, low cost, small equipped power, clean separation of grain and stalk powder, convenient bagging of grain, no air pollution, timely halt and rescue treatment, no need of wheat sundrying treatment and capablities of cutting and smashing cornstalks.

Description

technical field [0001] The invention relates to a grain threshing and stalk cutting machine in agricultural machinery, in particular to a wheat threshing and corn stalk cutting machine. Background technique [0002] At present, the working process of the known wheat threshing and selecting machine is: wheat enters the threshing bin from the feeding port, the crushed straw falls through the straw outlet, and then blows out of the bin with a blower, and the wheat grains and wheat residue flow to the sieve plate for further processing. Screening and separation, however, in the process of screening and separation, some wheat grains will still be blown out together with the straw powder, the separation of wheat grains and straw powder is not thorough enough, these wheat grains are mixed with many broken straws and glumes, it is a pity to discard them, It is troublesome to choose; besides, the strong wind of the blower will flow the dust back to the feeding port and fly, causing s...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the existing wheat threshing and selecting machines, and provide a wheat threshing and corn stalk cutting machine with compact structure, small body, light weight, low cost, convenient operation, use and transportation, and small power for matching. , the wheat grains and straw powder are separated cleanly, it is very convenient to bag the grains, the dust will not flow back and fly, it will not pollute the air, and it will be shut down in time to save people, and there is no need to dry the wheat, and the wheat harvested from the farmland can be directly threshed It can also cut and crush corn stalks, which is convenient for individual farmers to use
