A low-loss peanut seed shelling machine

Abstract

The invention relates to a low-loss peanut seed huller, and belongs to the technical field of agricultural machinery.According to the low-loss peanut seed huller, flexible materials are continuously arranged on the outer circle of a hulling drum, a roller bar with a semicircle section is made, and each knock out rod of a concave plate screen is formed by winding a flexible material with helical grooves outside a metal core; an air outlet of a lifting fan of the huller is composed of a gradually necked section and a circular arc section, the included angle between the bottom horizontal edge and the top inclined edge of the gradually necked section is 10-20 degrees, and the circular arc section extends into the lower portion of the vertical-direction inlet end of a 90-degree circular arc elbow and extends to the portion corresponding to 25-30 degrees of the central angle of the circular arc elbow; a discharging hopper is provided with a vertical wall which is attached to a vertical-direction inlet and reaches the upper edge of the air outlet, and a discharging opening is formed in the lower portion of the vertical wall and provided with a suspension door curtain; the horizontal outlet end of the circular arc elbow is connected with the lower end of a lifting pipeline.The low-loss peanut seed huller decreases the breakage rate of peanut seeds after the hulling process and effectively avoids the blowout loss, subsequent positive-pressure blowing and lifting are promoted, the hulling operation quality is significantly improved, and the efficiency is significantly improved.

Description

technical field [0001] The invention relates to a peanut sheller, in particular to a low-loss peanut seed sheller, which belongs to the technical field of agricultural machinery. Background technique [0002] Shelling is an indispensable key link in peanut seed production. It has been relying on manual work for a long time, which is labor-intensive, time-consuming and costly. For this reason, the horizontal rotary beating bar peanut shelling machine is used for carrying out the peanut shelling operation after being developed. When the machine is working, the peanut pods are hit by the rigid rotating rod, and the rotating rod and the concave plate sieve are combined to squeeze and knead the peanuts, so that the peanut pods are broken and the kernels are separated. After passing through the concave screen, the kernels are cleaned by a cleaning fan. [0003] However, practice has proved that the machine has a high breakage rate and poor variety adaptability during operation, ...

AI Technical Summary

Problems solved by technology

[0006] However, practice has proved that the existing compound peanut shelling machines still fail to solve the problems of high damage rate and poor variety adaptability, and the air lifting device is directly blown by a traditional fan, so it is inevitable that air leakage and wind force will be caused by unreasonable air duct design. The sudden drop affects the lifting efficiency and causes a large blowing loss of peanuts
