Straw briquetting machine

Abstract

The invention relates to a straw briquetting machine. The straw briquetting machine comprises a ring die (1), a base (2), a pressing roller (3), an eccentric shaft (4), a pressure cover (5), a main shaft (6), an abrasive disk (8) and an upper pressure plate (13), wherein the central hole of the base (2) is provided with a central main shaft (6); the straw briquetting machine is characterized in that the main shaft (6) drives the abrasive disk (8) to rotate; the abrasive disk (8) drives the eccentric shaft (4) to rotate; and the pressing roller (3) rotates around the main shaft (6) on the eccentric shaft (4). Straw fed from a feeding port (14) of the ring die (1) is continuously compressed in the space of an abrasive cavity and extruded from a discharge port (15) to prepare finished products, and the straw briquettes are formed. By adopting the straw briquetting machine, the production efficiency of the straw briquette is improved, the power consumption is reduced, the production cost is lowered; and a roller is connected with the abrasive disk through the eccentric shaft, so that the gap between the roller and an extrusion die can be adjusted, the production efficiency is improved, the service lives of the extrusion die and the roller are prolonged, and the safety is enhanced.

Description

technical field [0001] The invention relates to an agricultural straw briquetting machine, in particular to a straw briquetting machine with high working efficiency. Background technique [0002] Most of the currently known straw briquetting machines are improved by imitating foreign models. Although they have developed rapidly in recent years, the overall technology is still relatively backward. Most of the straw briquetting machines have low working efficiency, Problems such as high energy consumption and low output have affected the popularization and use of straw briquetting machines. Chinese patent specification: 201010578710.4 (cross shaft form) discloses a straw briquetting machine. The lower mold body of the briquetting machine is provided with an outer mold cavity ring and an inner mold cavity ring respectively corresponding to the outer upper pressure gear and the inner upper pressure gear. Shaft, although this patent can improve production efficiency, it also ha...

AI Technical Summary

Problems solved by technology

The lower mold body of the briquetting machine is provided with an outer mold cavity ring and an inner mold cavity ring respectively corresponding to the outer upper pressure gear and the inner upper pressure gear. Shaft, although this patent can improve production efficiency, it also has complex structure, high production cost, and problems such as wolf teeth, outer mold cavity ring and inner mold cavity ring that are easy to wear and difficult to replace.

Chinese patent, application number 201110059320 invention patent (a rolling shear type straw briquette forming machine) discloses a straw briquetting machine, although the application improves the production efficiency, it is not easy to crash and the straw is not easy to carbonize, but The structure of the whole machine will cause large vibration, and the upper discharge hole is not easy to discharge, which is easy to cause blockage, and the wear is serious.
