Straw compressing machine

Abstract

The invention discloses a straw compressing machine. The straw compressing machine comprises a lower pressing plate, wedge blocks, an upper pressing plate and an extrusion device, wherein the wedge blocks which are uniformly distributed circularly are arranged between the upper pressing plate and the lower pressing plate; the lower pressing plate, the wedge blocks and the upper pressing plate arefixedly connected through fixing bolts; the extrusion device is arranged in the lower pressing plate and the upper pressing plate and is driven by a driving shaft; a protection shield is arranged on the top of the upper pressing plate; a material inlet is formed in the top of the protection shield; and a material outlet is formed between every adjacent wedge blocks, the upper pressing plate and the lower pressing plate; and a material guiding device is arranged on the bottom of the lower pressing plate. The straw compressing machine has the advantages that defects of a traditional compressingmachine are overcome; simple maintenance and adjustment are realized; requirement on plant straws is low; adaptability is high; use is convenient; and efficiency is high.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a straw briquetting machine for processing agricultural and forestry products such as corn stalks, peanut stalks and wheat straws into cuboid small pieces. Background technique [0002] Straw briquetting refers to the use of biomass compression equipment to process agricultural and forestry products such as corn stalks, peanut stalks, and wheat straws into small cuboids. The density is generally between 0.7-1.3, and the cross-sectional diameter is generally 3-3. -10CM, the length is generally 2----10CM, the main feature is that it is convenient for storage and transportation, and reduces the cost of storage and transportation. If used as a fuel, it can also greatly improve the thermal efficiency of biomass. At the same time, due to the mechanical extrusion and high temperature in the compression process, the physical and chemical properties of the straw will change, so that...

AI Technical Summary

Problems solved by technology

However, the structure of the traditional straw briquetting machine is relatively closed, and maintenance and replacement are time-consuming and labor-intensive. At the same time, there are strict requirements for the cutting precision of the extruded materials. Some types of straw are too thick when the cutting is insufficient. The area will be blocked and cause the operation of the briquetting machine to fail; the existing equipment has poor applicability to the different sizes of plant straws cut by the guillotine
