Peanut shelling and screening device

Abstract

The invention discloses a peanut shelling and screening device and belongs to the field of agricultural machinery. A peanut shelling body comprises a shell with the interior of a hollow structure anda rotary beating assembly installed in the shell; the shell comprises an upper shell body and a lower shell body which are arranged up and down, the interior of the lower shell body is provided with acurved concave-plate sieve for separating broken fruit shells, extracted nuts and complete peanut pods, a rotary pressing roller is arranged below the curved concave-plate sieve and mounted at an outlet of the lower shell body, and the two ends of the rotary pressing roller are mounted on the side walls of the lower shell body and can conduct rotary movement in the axial direction of the rotary pressing roller. The device has the advantages that the rotary beating assembly and the rotary pressing roller are adopted for conducting shelling treatment twice, and the shells of the complete peanutpods are subjected to preliminary beating by the rotary beating assembly, it is ensured that most of the nuts are removed from the fruit shells while the inner nuts are not damaged, and then the rotary pressing roller applies a force to the fruit shells inside which the nuts still remain, so that the nuts are pressed out from the fruit shells.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a peanut shelling and screening device. Background technique [0002] Peanut shelling machine is to take off the peanut shell through the high-speed rotating body, and keep the peanut fruit from damage. In the process of mechanical shelling of peanut pods, there are common problems such as high damage rate, low cleaning rate and serious loss, which not only directly affect the income of agricultural products, but also relate to the quality and cost of subsequent peanut processing. At the same time, the damaged peanut kernels lack intact Clothing protection, aflatoxin is very easy to infect, and there are potential hazards. Contents of the invention [0003] In order to overcome the problems of high damage rate and low removal rate of peanut pods caused by shelling by pure hitting method in the prior art, the present invention provides a peanut shelling and screening devic...
