The main working principle of a scraper

The working principle of a scraper mainly depends on the hydraulic system. A hydraulic pump converts mechanical energy into hydraulic energy and compresses hydraulic oil before sending it into a hydraulic cylinder. The hydraulic cylinder includes a piston and a piston rod. When hydraulic oil enters the hydraulic cylinder, the piston moves in one direction, which makes the hydraulic cylinder have a telescopic function. The bucket is connected by a piston rod and is connected to the body through a support arm. When the piston extends outward, the piston rod will push the bucket forward, thereby picking up objects; On the contrary, when the piston contracts inward, the bucket will tilt towards the body and unload the object.
