Adjustable material limiting device of scraper conveyor

Lengthening plates are welded to the two sides of a middle groove, a baffle and a side plate which have a certain inclination angle are arranged above the lengthening plates, a sliding groove is formed in the side plate, a mother plate and an inserting plate are installed in the sliding groove, the mother plate is fixed to the upper portion of the sliding groove, a plurality of threaded holes are formed in the two sides of the mother plate and the two sides of the side plate, and the inserting plate is fixed to the middle groove. Bolts are inserted into the threaded holes, and the insertion plates are fixed at the specified height through the bolts; according to the adjustable material limiting device of the scraper machine, the material limiting height can be adjusted, materials can be prevented from being accumulated in a concentrated mode in the material cleaning process, and the problems that a material discarding sealing-tape machine is pressed and stopped or materials are scattered in a material guide g
