Abstract

The invention discloses a novel dust-free rice thresher which comprises a feeding module, a threshing module and a winnowing module. The feeding module comprises a feeding shell and a transmission motor, the transmission motor drives the feeding shell to rotate at a low speed through a speed reducing mechanism, and a plurality of feeding openings are evenly distributed in the feeding shell; each feeding port is provided with a clamping assembly for clamping rice stems, the threshing module comprises a beating roller and a hopper, the beating roller is arranged in the feeding shell and driven by the transmission motor to rotate at a high speed, the beating roller is provided with a plurality of evenly-distributed beating pieces, the hopper is arranged below the feeding shell, and the hopperis of a hollow cavity structure; and the winnowing module is arranged in the hopper and comprises a draught fan, a dust collecting box, a dust guiding channel and a discharging channel, the draught fan is arranged at one side of the hopper, the dust collecting box and the dust guiding channel are arranged at the other side of the hopper, and the discharging channel is arranged at the bottom of the hopper. Rice is threshed, the manual threshing efficiency is improved, the labor intensity is reduced, and dust is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a novel dust-free rice thresher. Background technique [0002] In southern China (and other rice-growing areas), rice is mainly used as the main food crop. However, based on the basic national conditions of our country, the land of most farmers in our country is relatively scattered, and many rice fields (such as Southwest China) are distributed in areas that are not suitable for large-scale agricultural machinery, such as hilly areas, plateau mountains, and basins. Harvesting of rice in these areas cannot be done using large combine harvesters. After farmers harvest manually or by small machines, small rice threshers are often needed to separate the grains from the stalks. [0003] When using the existing rice thresher to thresh rice, because the threshing roller will produce a lot of dust or debris when rolling the straw, these dust or debris will splash or esc...
