Description

Agricultural wheat thresher

Technical Field

The invention relates to the technical field of agricultural production, in particular to an agricultural wheat threshing machine.

Background

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.
