Scraper is a kind of shovel transportation machine that uses a bucket to shovel the soil and loads the crushed soil into the bucket for transportation. Real integrated operations. It is suitable for leveling work on railways, roads, water conservancy, electricity and other projects. Scrapers have the advantages of simple operation, unrestricted by terrain, independent work, fast travel speed, and high production efficiency. It is suitable for one to three types of soil. For example, when cutting more than three types of soil, it is necessary to loosen the soil beforehand. The scrapers widely used in the market are divided into two types: internal combustion scrapers and electric scrapers. Internal combustion scrapers are suitable for well-ventilated operating environments and have flexible and efficient features. Electric scrapers are more environmentally friendly. Pollution. The characteristics, structure, classification, development achievements, operation process and safety regulations are introduced in detail.
Scrapers, including wheels, traction beams, frames, hydraulic devices, buckets with a shovel mechanism, a bracket mechanism, and a frame lifting adjustment mechanism, are characterized in that the bucket with the shovel mechanism is composed of a bucket body , Sliding baffle, rotating baffle, blade and shovel; on each of the two side walls of the bucket, there is a support rod shaft and the bucket rotation support shaft hole, The inside of the front end is provided with a slideway, the blade is welded to the front end of the bucket body, and the shovel blade is welded to the blade; Two hinges are connected, and the two ends of the two hinges exit the shaft and are respectively inserted into the slideways on the inner sides of the front ends of the two side walls of the bucket; the bracket mechanism is composed of a baffle rod, two side rods and a front branch. The front end of the front support rod is supported by the front support rod support shaft fixed at the front end of the frame. The rear end shaft hole of the front support rod is sleeved into the baffle support rod and is located in the middle of the baffle support rod. The support rod is fixed at the upper end of the sliding baffle, and the shaft is left at both ends. The front end of the 2 side support rods has a shaft hole, and the rear end has a slide groove. 2 The front shaft holes of the side poles are respectively set on the shafts at the two ends of the baffle pole, and the rear chute of the two side poles are respectively fitted on the two pole shafts on the bucket body; two bucket bodies The supporting shaft passes through two bucket body rotation support shaft holes on the two side walls of the bucket body and the shaft holes on both side walls of the frame, and the lifting rod of the hydraulic device is connected with the horizontal shaft fixed at the rear end of the bucket body; The frame lifting and adjusting mechanism is composed of a screw rod, a screw mother disc and a turntable. The turntable is fixed on the top of the screw rod. The screw mother disc is connected to the frame to form an integrated structure. The screw rod is screwed into the screw mother disc and its lower end is inserted into the traction beam. Screw end hole.
