Straw compression mold capable of automatically removing wall surface, for measuring straw springback after compression

Abstract

The invention belongs to the technical field of agricultural machinery, and relates to a straw compression mold capable of automatically removing a wall surface, for measuring straw springback after compression. The mold consists of a bottom plate assembly, a front plate assembly, a left plate assembly, a rear plate assembly, a right plate assembly and an automatic compaction system, stepping motors in the automatic compaction system can lock a motor rotating shaft without rotating during straw compression; therefore, gears can be locked, racks and four plate surfaces are further locked, and a fixing effect is achieved; and after straw compression is completed, a stepping motor can drive the front, rear, left and right plate surfaces to automatically move out, so that the resilience of pressed straw blocks can be accurately measured, the straw compression process and parameters can be optimized, and the invention aims to improve the straw compression efficiency and density, reduce the energy consumption and realize efficient, high-quality and low-energy straw compression. The straw compression mold has important significance in improvement of a straw briquetting machine and a straw bundling machine.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an automatically removable wall surface-type straw compression mold for measuring the rebound of straw after pressing, referred to as a straw compression mold. Background technique [0002] Crop straw is an important biomass resource. The world's annual output exceeds 2 billion tons, and my country's annual output exceeds 900 million tons. Straw is rich in organic matter and various nutrients such as nitrogen, phosphorus, potassium, and calcium, and can be used as fuel, feed, and fertilizer. , base materials and industrial raw materials, etc., have high use value. However, due to loose straw, low density and scattered distribution, the utilization rate of straw is low. Compression is a necessary process for the resource utilization of straw, which can increase the density of straw and facilitate the transportation and storage of straw, thereby reducing ...

AI Technical Summary

Problems solved by technology

However, there is no in-depth and systematic research on the springback of straw after pressing. Therefore, the present invention can accurately measure the springback of straw after pressing, and can be used to optimize the straw compression process and parameters, aiming at improving the compression efficiency and Density, reduce energy consumption, realize high-efficiency, high-quality and low-energy compression of straw, which is of great significance to the improvement of straw briquetting machine and straw baler
