Abstract

A rice granular harvesting machine is a machine which can harvest rice granular in humid and soft field. According to the rice granular harvesting machine, a threshing device is designed by utilization of binding force of ears of rice when rice straws are not broken and the characteristics of loose and easily threshing. Threshing teeth are driven by power and inserted into the ears of rice forward, and then grain of rice are combed upward and flung backward. An inlet of a separate-collect cabin which is arranged at the back receives the flung grain of rice and impurities. Due to the fact that the cabin is filled with air, light impurities are flown out from the rear end along with wind, heavy grain of rice stay in the cabin, and the purpose of separation is achieved. The ground contacting surface of driving wheels of a base plate of the rice granular harvesting machine is large so that the machine is not prone to being sunk into the ground. The direction of turning of upper teeth of two wheels is reversed, when the two wheels rotates, the rice granular harvesting machine can be driven to move forward or backward. When one wheel does not rotate, the rice granular harvesting machine can turn. The rice granular harvesting machine has the advantages of being small, exquisite, light, capable of being operated in small fields, strong in climbing force, low in price, suitable for being used by single household, and convenient to popularize.
