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.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, 2 and 3, a screening apparatus of a grain threshing machine includes a piston vibrator 2, and is characterized in that a piston vibrator 2 is fixedly installed at a central position of the bottom of the inner side of a box 1, an output end bracket 3 of the piston vibrator 2 is fixedly connected, a first chute 4, a second chute 5 and a third chute 6 are sequentially formed at the left and right sides of the bracket 3 from top to bottom, the first chute 4 is provided with a first screen 7 between two first chutes 4, a first baffle 8 is respectively formed at both sides of the first screen 7, a second screen 9 is provided between two second chutes 5, a second baffle 10 is respectively formed at both sides of the second screen 9, a grain collecting middle plate 11 is provided between two third chutes 6, a third baffle 12 is respectively formed at both sides of the grain collecting middle plate 11, a feed inlet 13 is formed at the top of the box 1, a discharge hole 14 is formed at the left side of the box body 1, and a fourth baffle 15 is hinged at the front side of the box body 1.

A latch lock 16 is installed on the fourth baffle 15 to fix the position of the fourth baffle 15 and prevent the objects in the box body from leaking out.

Four apex departments of the bottom of box 1 respectively install an universal wheel 17, are convenient for remove the utility model discloses a position.
