Spiral deicing scraper for carrier roller

Provided is a carrier roller spiral deicing scraper. According to belt conveying equipment, in a cold region in winter, moisture attached to materials can form protruding ice on a roller and a carrier roller, the protruding ice can damage a belt, abrasion of a bearing can be increased, and the stability and efficiency of belt conveying are seriously affected, at present, a manual knocking mode is mainly adopted for deicing of the roller and the carrier roller, the efficiency is low, and the working efficiency is high. And the production continuity is seriously influenced. The device comprises a main shaft (1), a spiral scraper A (2) and a spiral scraper B (3) which are symmetrically arranged are welded on the main shaft, the spiral direction of the spiral scraper A is opposite to that of the spiral scraper B, the two ends of the main shaft are rotationally connected with a belt conveyor frame body (7) through connecting rods (4) respectively, and the main shaft is installed under a carrier roller (6) in paral
