A belt type material cleaning machine

Abstract

The belt-type material cleaning machine of the present invention comprises drive rollers supported on the frame and inclined axially at both ends in the length direction. The drive rollers are surrounded by flat belts; And the miscellaneous box is placed under the other end; the lower side of the flat belt is equipped with a discharge box; one end of one of the transmission rollers is equipped with a cam, and the cam and one end of the torsion rod hinged on the frame form a cam pair, and the torsion swings. The other end of the rod is provided with a long slot, which forms a moving pair with the dial pin extending from the torsion shaft sleeve, the torsion shaft sleeve is fixedly connected with the disturbance shaft, and the disturbance shaft is supported on the frame with the axis perpendicular to the movement direction of the flat belt. Circumferentially spaced fixed flaps under the flat belt. The invention has the advantages of simple structure principle, low cost and high working efficiency. By adding a disturbance mechanism, the accuracy of seed selection is improved, the loss of selection is reduced, one machine is multi-purpose, and the utilization rate of equipment is improved. The adjustment of the rotation angle of the disturbance shaft can realize the adjustment of different disturbance degrees required by different peanut varieties.

Description

technical field [0001] The invention relates to a material cleaning machine, in particular to a belt-type material cleaning machine suitable for peanuts, and belongs to the technical field of agricultural machinery. Background technique [0002] Belt cleaners are often used for sorting granular materials such as soybeans and mung beans. When working, according to the difference in material friction coefficient and rolling characteristics, half of the materials such as soybeans and mung beans can be removed to improve the quality of seeds. [0003] After peanut seeds are mechanically dehulled, most of the broken seeds are half-grained. In order to ensure the quality of the seeds, it is also necessary to remove the half-grained peanut seeds after dehulling. However, as far as the applicant knows, there is no special peanut half-seed removal equipment on the market at present. In order to improve the sorting efficiency, sometimes soybeans and mung beans have to be used to remo...

AI Technical Summary

Problems solved by technology

However, as far as the applicant knows, there is no special peanut half-seed removal equipment on the market at present. In order to improve the sorting efficiency, it is sometimes necessary to use belt-type cleaning equipment for soybeans and mung beans to remove peanut half-seeds.

[0004] Because the physical characteristics of peanut seeds are very different from those of soybeans and mung beans, most peanut seeds have an arc-shaped rugby ball shape with good rolling properties, and some intact peanut seeds have flat outer surfaces with poor rolling properties. The movement characteristics of the upper run are similar to those of a half-peanut. Usually, its flat surface is in contact with the belt of the belt-type material cleaning machine and remains relatively still, so it is mistakenly selected as a half-grain seed, and the sorting loss is relatively large.
