Agricultural machine used for threshing

Abstract

The invention discloses an agricultural machine used for threshing, and belongs to the field of agricultural threshing devices. The agricultural machine used for threshing comprises an outer box, an arc conveyor belt and a central rotating column, wherein an annular rack is arranged between the central rotating column and the arc conveyor belt, pressure rolls and scarifying assemblies are installed on the circumferential side of the central rotating column at equal intervals, and the sides, facing the central rotating column, of the pressure rolls are connected with first gears meshed with theannular rack; the scarifying assemblies comprise triangular turning conveyor belts and three rotating shafts, one rotating shaft is fixedly sleeved with a second gear, and the bottom of the second gear is meshed with a third gear meshed with the annular rack; and mesh holes through which beans penetrate are distributed in the arc conveyor belt, an isolation cylinder fixed to the bottom surface ofthe outer box is arranged between the arc conveyor belt and the central rotating column, and isolation baffles which are fixedly connected with the isolation cylinder and the bottom of the outer boxare fixed to both ends of the arc conveyor belt. According to the agricultural machine used for threshing, the threshing strength is adjustable, beanpoles can be turned, full threshing is ensured, andthe threshed beanpoles can be discharged fully automatically.

Description

technical field [0001] The invention relates to the field of agricultural threshing devices, in particular to an agricultural machine for threshing. Background technique [0002] After the soybeans are harvested, the traditional threshing method is rolling in the sun or manually beating and peeling, and then raising the field or using a windmill to winnow. The existing mechanical threshing of soybeans mostly uses a rice thresher for threshing, but the effect is very poor and cannot be effective. The soybeans are threshed directly from the bean stalk, and there are many remaining bean grains. The individual soybean threshers usually use the method of roller rolling or stirring and chopping for screening, which is easy to cause soybean grains to be broken, the threshing time is longer, and the threshing effect is poor. Difference. [0003] In the patent application publication number CN 110024570 A, an agricultural machinery soybean thresher is disclosed, which includes a cas...

AI Technical Summary

Problems solved by technology

But it has the following disadvantages: 1. After the device is installed, because of the linkage between the drive of the bean bar and the drive of the conveyor belt, the transmission of the bean bar is slow, and the movement of the bean bar is slow, and the movement of the bean bar is fast, and the action of the bean bar is slow. Faster, so that the beating intensity of the bean stems in the unit time remains basically unchanged, that is, the threshing intensity cannot be adjusted; After hardening, the inner bean grains are not easy to separate from the pods, which affects the adequacy of threshing; 3. When the threshing work is about to end, the threshed bean stems cannot be automatically discharged from the thresher
