Stevia rebaudiana disleaving device

Abstract

The invention discloses a stevia rebaudiana disleaving device which comprises a rack, wherein a feeding hole is formed in one end of the rack; a stem outlet and a leaf outlet are formed in the other end of the rack; a feeding compression roller group, a disleaving roller and a discharging compression roller group are sequentially arranged in the rack; the feeding compression roller group and the discharging compression roller group comprise upper compression rollers and lower compression rollers; the upper compression rollers are fixedly connected with an elastic device arranged on the top of the rack by virtue of a connecting rod; a fixing rod is tightly arranged on the connecting rod in a sleeving manner; the fixing rod is fixedly connected with the side wall of the rack; multiple disleaving knives are arranged on the outer circumference of the disleaving roller; and the adjacent disleaving knives are arranged in a staggered mode. According to the cutting effects of the staggered disleaving knives, leaf and stem separation can be conveniently, rapidly and efficiently finished at a high speed, leaves are completely removed, the device hardly has impurity residue and is high in disleaving speed, and the manual labor is saved.

Description

Technical field [0001] The invention relates to agricultural machinery, in particular to a stevia defoliation device. Background technique [0002] At present, farmers planting stevia in China generally use artificial methods to defoliate stevia plants after shade drying. Although it is not easy to break the leaves of stevia, the defoliation speed is slow and wastes manpower. Some people directly use soybean thresher to defoliate stevia. But because the principle of defoliation of stevia is quite different from the principle of threshing of various common crops, the rate of defoliation of stevia leaves with soybean thresher is very high, up to 50%, and the defoliation speed is not fast enough. It is not clean, the impurities contain leaves, and the protruding leaves contain stevia stems and impurities, and the defoliation effect is not good. Due to the poor quality of protruding stevia leaves, it directly affects the sales income of farmers. Summary of the invention [0003] The ...

AI Technical Summary

Problems solved by technology

[0002] At present, farmers who grow stevia in my country generally use manual methods to remove the leaves of stevia plants after shade drying. Although it is not easy to break the leaves of stevia, the speed of defoliation is slow and wastes manpower. Some people directly use soybean threshers to remove stevia. However, due to the large difference between the defoliating principle of stevia and the threshing principles of various common crops, the rate of defoliating stevia leaves with a soybean thresher is very high, up to 50%, and the defoliation speed is not fast enough. It is not clean, there are leaves in the impurities, and there are many stevia stalks and impurities in the prolapsed leaves. The defoliation effect is not good. Due to the poor quality of the prolapsed stevia leaves, it directly affects the sales income of farmers.
