Device for separating stalks, stems and leaves

Abstract

The invention discloses a method and device to separate the stalk from the leaf of the straw and relates to the agriculture mechanical domain. The method is to remove the topwood of the straw in batches, cut the straw to breaking sections of zero point two to one point five times, and then pave the straw in a single layer, squash and twist to enable the leaf to be separated from the stalk, and last the stalk and the leaf are separated through the air flow cleaning and choosing. The device of the invention comprises a feeding mechanism, a pair of rubber revolves and an air flow cleaning and choosing mechanism. The material arranging revolve of the feeding mechanism, and the two drip plates can realize the monolayer even material inlet and can enable the material to be fed along the length direction of the straw. The invention is especially suitable for the separation of the stalk and the leaf in the corn or broomcorn straw, has simple technique, low cost and is beneficial to the continuous operation. As the invention adopts the characteristic of the straw that the straw can be squashed and cut and can not influence the following processing or even bring convenience to the followingprocessing to separate the stalk with the leaf, the invention brings convenience to the industrialization of the straw resource.

Description

A straw stem and leaf separation device technical field The invention belongs to the field of agricultural machinery, and relates to a method and a device suitable for separating stems and leaves of corn and sorghum stalks. Background technique my country can produce more than 700 million tons of straw every year. In recent years, on-site burning of straw has become more and more serious, and the smoke produced has become a major social hazard. With the increasing urgency of global energy and environmental protection issues, the development and utilization of crop straw, a biomass resource, has attracted great attention at home and abroad. With the deepening of research, the application of renewable straw resources is becoming wider and wider, and the scale is getting bigger and bigger. Straw can replace wood to make paper, produce fiberboard, composite board, light wall, composite doors and windows, heat insulation board, packaging tray, and also replace foam plastic to...

AI Technical Summary

Problems solved by technology

The results show that this method is feasible, but the leaf removal rate is greatly affected by the moisture content and impact resistance of the straw, and the primary separation rate is low (less than 80%)

Moreover, the service life of the wire rope is relatively short, and the separation effect is not ideal.
