Description

Dustless rice harvesting and threshing machine

Technical Field

The invention relates to the technical field of harvesting and threshing machines, in particular to a dustless rice harvesting and threshing machine.

Background

Rice is a cereal crop of the genus Oryza, and the representative species is rice. The rice is native to China and India, the rice is planted by precedent people in Yangtze river basin of China seven thousand years ago, the rice is the rice seeds, the rice is called brown rice after the glume of the rice is removed, and the rice bran layer of the brown rice is removed to obtain the rice. Approximately half of the world population uses rice as staple food. Besides being edible, the rice can also be used as industrial raw materials for brewing wine and making sugar, and the rice hulls and rice straws can be used as livestock feed. The main production areas of Chinese rice are Yangtze river basin, Zhujiang river basin and northeast region. Rice belongs to direct economic crops, and rice is staple food of Chinese residents.

The thresher is a harvesting machine, which is a machine capable of separating crop seeds from stalks, and mainly relates to a grain crop harvesting machine. The thresher is of different types according to different grain materials. For example, the rice thresher is suitable for threshing rice; for threshing corn, a so-called "corn thresher" or the like is used. The thresher is commonly called a "thresher", and is the most common rice threshing machine. After the rice is harvested, the rice grains are separated from the stalks by the machine. The rice thresher is divided into two types, one type is driven by manpower, is called as a manpower rice thresher and is a semi-mechanized tool; the rice thresher is changed into power driving, so the rice thresher is called as a power rice thresher. The rice thresher greatly reduces the labor intensity of rice harvesting and improves the agricultural productivity at the same time.

With the development of the times, mechanized equipment gradually enters the lives of people, for example, a rice harvesting and threshing all-in-one machine is a machine for reducing the working strength of people, however, in small areas or fields with special terrains, people simplify and reduce a harvesting and threshing machine according to the requirements, and therefore the problems that the existing small-sized harvesting and threshing machine is inconvenient to bag and wastes straws are caused when in use.
