Among them, the first support drives three top transmission rollers to make the transmission belt bulge to form an inverted trapezoid, so that the material can fall on the bottom of the trapezoid to prevent it from falling off the transmission belt. Since the bottom of the chassis is hollow through roller transportation, the mining area environment is complex, there are many crushed stones, flying stones, etc., and there are losses caused by transportation. When a large amount of crushed stones and sundries accumulate at the bottom of the mining conveyor belt and are not cleaned, it will damage the conveyor belt and affect its function. The air cylinder drives the connecting rod to make the scraper for mining move back and forth like a broom at the bottom of the chassis to sweep the crushed stones out of the chassis to the outside of the machine. A small part will stay at the edge of the conveyor belt, and the rotating sweeping plate can sweep out the edge crushed stones that the scraper cannot clean to prevent them from entering the chassis. Thus, the treatment of the hollow bottom of the chassis can be completed, and the problem of difficult transportation of the mining conveyor belt can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS
