Low-loss peanut seed shelling device

Abstract

The present invention relates to a low-loss peanut seed shelling device and belongs to the technical field of agricultural machinery. The device comprises a shelling roller with rolling bars arranged at intervals in an outer circumferential direction and an arc concave sieve with hitting rods arranged circumferentially at intervals. The concave sieve is arranged under the shelling roller and the arc of the concave sieve is concentric with the shelling roller. The rolling bars with semicircular sections and made from flexible materials are continuously arranged at the outer circle of the shelling roller, and the hitting rods of the concave sieve are formed by wrapping metal cores with flexible materials having spiral grooves. Due to the fact that the shelling roller and the hitting rods all have flexible surfaces, rigid hitting of the peanuts are avoided and the breaking rate after the peanut seeds are shelled is reduced. Besides, the shelled peanut nuts timely leak out along the spiral grooves to avoid unnecessary retention between the shelling roller and the concave sieve, and thus the damages are further avoided and the shelling operation quality is remarkably improved.

Description

technical field [0001] The invention relates to a peanut shelling device, in particular to a low-damage peanut seed shelling device, 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. However, practice has proved that the machine has a high breakage rate and poor variety adaptability during op...

AI Technical Summary

Problems solved by technology

However, practice has proved that the machine has a high breakage rate and poor variety adaptability during operation, so it is difficult to meet the germination rate requirements of seed peanuts.

Research and analysis shows that the reason for the above problems in the prior art is that the key factors affecting the shelling quality, such as the motion parameters of the rotating rod of the peanut sheller, the structure and material of the concave screen, are unreasonable

[0003] It can be seen from the search that the Chinese patent documents with application numbers CN201210513313.8 and CN201220660852.X provide improvements to the shelling drum, one of the key components of peanut shelling equipment, although this improvement reduces the peanut shelling process to a certain extent. However, because the structure mainly reflects the unilateral flexibility of the drum, the peeled peanut seeds and nuts cannot be separated quickly, and the application effect is still unsatisfactory.
