Screen for rice sieving machine

Abstract

The invention relates to the technical field of rice sieving equipment, in particular to a screen for a rice sieving machine. The rice sieving machine comprises a screen frame and two screens, wherein limiting plates are symmetrically arranged at the two sides of the screen frame; multiple limiting plates are vertically and uniformly distributed on the screen frame; the distances between all the limiting plates at the same side are equal to the thicknesses of the screens; the limiting plates are provided with connecting holes; locking bolts are arranged in the connecting holes; the screens are provided with through holes corresponding to the connecting holes, and are connected with the limiting plates through the locking bolts; and all the screens are connected to the adjacent limiting plates. Compared with a traditional screen, the equipment only needs one type of screen to combine different types of screen holes to satisfy actual demands, so that the cost is saved for users, the installation trouble is reduced, and the screen is practical.

Description

technical field [0001] The invention relates to the technical field of rice screening machine equipment, in particular to a screen used for the rice screening machine. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest kind of grain in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. It is an annual, gramineous plant, monocotyledonous, sexually warm and humid, about 1 to 1.8 meters high when mature, with slender leaves, about 50 to 100 cm long and 2 to 2.5 cm wide. The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 cm below the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. Generally, the size of the rice ear is 5 to 12 mm long and 2 to 3 mm thick. Rice is native to China and is one of the world's main food crops. The sown are...

Problems solved by technology

The traditional screening work is screened by manual shaking. The screening effect of this method is greatly affected by human factors, the screening effect is not good, and the labor consumption is large and the efficiency is low.

The improved screening machine is used to screen through the screen, but due to the limitations of the screen structure design, for mass production, the mesh size is certain, and the same type of screen cannot meet various screening requirements. When it is necessary to install various types of screens to meet the screening requirements, it will cause inconvenience to users. Therefore, it is necessary to make improvements
