A three-stage sorting device for chestnuts

Abstract

The invention discloses a three-stage sorting device for castanea mollissima. The device comprises that rolling wheels are rotationally connected to the side wall of a turning plate; a partition plateis arranged at the lower end of the turning plate; the middle part of the turning plate is fixedly connected with the upper end of a screw rod; the partition plate is sleeved with the screw rod; a driving motor is arranged on the lower portion of the right end of the device body; a driving shaft is rotationally connected to the left end of the driving motor, and an eccentric wheel is fixedly connected to the middle of the driving shaft; the upper end of the eccentric wheel abuts against the lower surface of a inclining guide plate; the lower part of the screw rod is sleeved with the middle ofthe inclining guide plate; ends of the inclining guide plate are connected with guide grooves in a sliding mode; the left end of the driving shaft is fixedly connected with an incomplete bevel gear;the screw rod surface is threaded connected with a lantern ring; and fixing rods are fixedly connected to two sides of the lantern ring. The device drives a turnover plate to swing in a reciprocatingmode through the screw rod, so that the castanea mollissima is intermittently discharged onto a material guide pipe and the inclining guide plate, particles with smaller particle sizes in the castaneamollissima are preliminarily separated through the material guide pipe, and then the particles are further separated by the inclining guide plate. The device is adaptable and reasonable in structuraldesign, the castanea mollissima sorting efficiency is greatly improved, the castanea mollissima with three different particle sizes can be separated at the same time, and the labor force is saved.

Description

technical field [0001] The invention relates to an agricultural screening device, in particular to a chestnut three-stage sorting device. Background technique [0002] The minerals in chestnuts are also very comprehensive, including potassium, zinc, iron, etc. Although the content is not as high as that of hazelnuts, it is still much higher than ordinary fruits such as apples, especially the potassium content is 3 times higher than that of apples. Chestnut, known as the "King of Dried Fruits", has another name called chestnut, big chestnut, and chestnut. Chestnut nuts are purple-brown, covered with yellow-brown hairs, or nearly smooth, with light yellow flesh, sweet and delicious taste. [0003] Chestnut not only contains a lot of starch, but also contains many signature nutrients such as protein and vitamins, and is known as the "king of dried fruits". Chestnuts can be used as food substitutes, and together with dates and persimmons, they are called "hardcore crops" and "...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the existing chestnut sorting devices can only separate chestnuts with two types of particle sizes, and some devices with three-level sorting often make the second-level sorting not thorough enough to cause the third-level sorting when performing the second-level and third-level sorting. The grade sorting effect is not good, and the work efficiency is low. The traditional sorting process still relies on manual work, which consumes a lot of labor
