Self-cleaning mechanical scraper knife of scraping machine

Abstract

The invention belongs to the field of machinery, and particularly relates to a self-cleaning mechanical scraper knife of a scraping machine. The self-cleaning mechanical scraper knife comprises a scraper knife bucket with scraper teeth fixed at the front end and a cleaning shovel structure, wherein a side baffle is fixed on each of two sides of the scraper knife bucket, and the cleaning shovel structure is connected onto the side baffles in a sliding manner; a chain used for driving the cleaning shovel structure to slide along the surface of the scraper knife bucket is arranged in each side baffle, and the chains are in power transmission connection with a double-shaft motor; and a shovel table is arranged on the cleaning shovel structure. Furthermore, the double-shaft motor can drive thecleaning shovel structure to slide along the surface of the scraper knife bucket by means of the chains, automatic cleaning is achieved through utilizing the shovel table arranged on the cleaning shovel structure, on one hand, discharging is facilitated, on the other hand, the surface of the scraper knife bucket is kept clean, the scraper knife bucket is prevented from sticking to extrude materials, and normal operation of the scraper knife is not affected.

Description

Technical field [0001] The invention relates to the field of machinery, in particular to a self-cleaning shovel mechanical blade. Background technique [0002] Shovel is a machine used for digging and transporting soil. The soil scraped by the scraper can be automatically loaded into the bucket and transported away. It uses a bucket to excavate materials above or below the bearing surface, and load them into transport vehicles or unloaded to the earth-moving machinery of the stockyard. The excavated materials are mainly soil, coal, silt and pre-loose soil and rock. [0003] When cleaning up some materials with high viscosity, such as soil and silt, they tend to stick to the blade. Squeezing slowly will cause the blade to become smaller. On the one hand, the shovel is not sharp and efficient, and on the other hand This will cause the scraped material to become smaller in volume and difficult to discharge. In the prior art, most of the manual cleaning is performed when not in use, ...

AI Technical Summary

Problems solved by technology

[0003] When cleaning up some viscous soil, silt and other materials, it is easy to stick to the shovel blade. Slowly squeezing will cause the shovel blade to become smaller. On the one hand, the shovel is not sharp enough and efficient. It will cause the volume of the removed materials to become smaller and it is difficult to discharge the materials. Most of the existing technologies are manually cleaned when not in use, which in turn will cause the cleaning efficiency to become low.
