A toothed roller and a pressure roller for stripping fiber crops

Abstract

The invention relates to a tooth space roller. The tooth space roller comprises a roller shaft and a plurality of roller teeth arranged on the roller shaft, wherein the top surfaces of the roller teeth are planes; the roller teeth surround the surface of the roller shaft in the circumferential direction of the roller shaft, and intervals are formed between adjacent roller teeth; the roller teeth are arranged on the surface of the roller shaft side by side in the axial direction of the roller shaft, and intervals are formed between adjacent roller teeth; the intervals in the circumferential direction of the roller shaft continuously constitute tooth spaces. Meanwhile, the invention provides a press roll comprising the tooth space rollers and used for peeling fiber crops. The press roll can provide sufficient rolling force regardless of thickness of stalks and damage xylem structures in the stalks of the fiber crops, preliminary bast and stem separation is realized, follow-up processing procedures are reduced, the processing cost is reduced, and the problem that a press roll on a bast fiber crop peeling machine for production breaks off bast fibers is solved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a toothed roller and a pressing roller for stripping fiber crops. Background technique [0002] Hemp fiber is one of the traditional textile raw materials in our country. Among many textile fibers, hemp fiber is the natural fiber with the most potential function. Raw hemp fibers can only be obtained through peeling of hemp crops, and the pressing roller is a device commonly used in hemp peeling machinery to initially destroy the connection between the hemp bone and the bast in the stem. Most of the existing pressing rollers are cast pressing rollers with heavy weight. When the gap between the upper and lower pressing rollers is large, the thinner stalks cannot be separated; The axial force directly acts on the bearing through the shaft, resulting in damage to the bearing seat, bringing potential safety hazards, and also causing damage or breakage of bast fibers of...

Problems solved by technology

Most of the existing pressing rollers are cast pressing rollers with heavy weight. When the gap between the upper and lower pressing rollers is large, the thinner stalks cannot be separated; The axial force directly acts on the bearing through the shaft, causing damage to the bearing housing, bringing safety hazards, and also causing damage or breakage of bast fibers of hemp crops, affecting the use of subsequent processes and causing economic losses

The Chinese Patent Publication No. CN204509511U mentions an elastic tooth structure, which can automatically adapt to the thickness of the raw material by arranging elastic spiral steel bars on the roller shaft, providing a pressing force that matches the raw material, and ensuring that the pressure roller is normal. At the same time of pressing, it can effectively avoid the damage of the bearing seat or the breakage of the fiber caused by the unbalanced force of the pressure roller; but this elastic method has a limited pressure on the stalk rolling. , the radial force is still very large, which does not fundamentally solve the problem of high bone strength and damage to the bearing seat, and cannot destroy the xylem of the fiber stem, which increases the subsequent process of bone bone treatment, resulting in excessive processing costs. High, do not use industrialization promotion
