Biomass molding machine push rod dust blocking device

Abstract

A push rod dust blocking device for a biomass briquetting machine is used for scraping away dust on a push rod and preventing the dust from entering a lubricating oil way and polluting lubricating oil. The push rod making reciprocating linear motion is arranged in a machine case. The acting end of the push rod is provided with a material collecting mold. A material blocking sleeve is fixed to the portion, close to the material collecting mold, of the machine case. The push rod is sleeved with the material blocking sleeve in a spaced manner. The inner cavity wall of the material blocking sleeve is provided with a plurality of round dust collecting grooves. One side of the material blocking sleeve is provided with a dustproof base fixed to the machine case. The push rod penetrates an inner cavity of the dustproof base. An air blowing port is formed in the upper portion of the dustproof base. A dust falling port is formed in the lower portion of the dustproof base. A dust storage box is arranged below the dust falling port. A dustproof ring base is arranged in the inner cavity of the dustproof base. A plurality of dustproof rings are arranged in the inner cavity of the dustproof ring base. The inner cavity walls of the dustproof rings make close contact with the outer wall of the push rod. The push rod dust blocking device can scrape away the dust on the push rod three times, and the dust is prevented for entering the lubricating oil way.

Description

technical field [0001] The invention relates to the technical field of biomass molding machines, in particular to a dust blocking device for push rods of biomass molding machines. Background technique [0002] Biomass molding machine refers to the use of rural corn stalks, wheat straws, cotton stalks, straw, rice husks, peanut shells, corncobs, branches, leaves, sawdust and other crops and solid waste as raw materials, which are pressurized and increased after being crushed. Dense molding, the production of "straw coal" machine. The main components of the biomass molding machine are the aggregate mold and the push rod. The biomass continuously enters the aggregate mold, and the push rod continuously squeezes the biomass in the aggregate mold to realize the compaction of the biomass. In the process of biomass compaction, the dust on the biomass is easy to stick to the push rod. Since the push rod reciprocates in the body, the dust on the push rod can easily enter the lubrica...

AI Technical Summary

Problems solved by technology

In the process of biomass compaction, the dust on the biomass is easy to stick to the push rod. Since the push rod reciprocates in the body, the dust on the push rod can easily enter the lubricating oil passage and contaminate the lubricating oil.
