Scraper is a kind of mine trackless equipment, widely used in underground mining, transportation, etc. So do you know its characteristics and structure? This article focuses on elaborating for you.
1. Characteristics of scraper
Scraper belongs to an integrated machine for shoveling and transporting soil. The gist of the present invention is to design a bucket with a shovel mechanism composed of a bucket body, a shovel blade, a soil breaking knife, a rotating baffle, and a sliding baffle, and a front support bar, 2 side support bars, and a baffle Bracket mechanism composed of rods.
The rotating baffle and the sliding baffle are arranged at the opening of the bucket body, and the two are connected by a hinge. The two ends of the hinge are inserted into the sliding groove at the front end of the bucket body and can move along the sliding groove.
The blade is welded and fixed to the front end of the bottom of the bucket body, and the earth-breaking blade is welded and fixed to the blade. The bracket mechanism is used to control the lifting of the sliding baffle and the rotating baffle.
The invention has simple structure and high construction efficiency, and is suitable for repairing river dams and removing sludge after floods.
2. Structure of scraper
1. Scraper, including wheels, traction beams, frame, hydraulic device, bucket with shovel mechanism, bracket mechanism and frame lifting adjustment mechanism, characterized in that the bucket with shovel mechanism is Composed of bucket body, sliding baffle, rotating baffle, shovel blade and earth breaking knife.
2. On each side wall of the bucket body there is a supporting rod shaft and a rotation supporting shaft hole of the bucket body. On the inside of the front end of the two side walls of the bucket body, there is a slideway, and the blade is welded to the front end of the bottom of the bucket body. The earth-breaking blade is welded to the blade.
3. The sliding baffle and the rotating baffle are set at the opening of the bucket body. The sliding baffle and the rotating baffle are connected by two hinges, and the two ends of the two hinges are out of the shaft and inserted into the two side walls of the bucket body respectively Inside the slideway inside the front end.
4. The bracket mechanism is composed of a baffle rod, two side rods and a front rod. The front end of the front rod is supported by the front rod support shaft fixed at the front of the frame, and the rear of the front rod The end shaft hole is inserted into the baffle rod, and is located in the middle of the baffle rod. The baffle rod is fixed to the upper end of the sliding baffle, the shaft is left at both ends, and the front end of the 2 side rods has a shaft hole. The rear end has a chute, the front end shaft holes of the two side struts are respectively sleeved on the shafts at both ends of the baffle rod, and the rear end chute of the two side struts are respectively sleeved on the bucket body On the shaft.
4. Each bucket body support shaft passes through two bucket body rotation support shaft holes on both side walls of the bucket body and the shaft holes on both side walls of the frame, the lifting rod of the hydraulic device and the horizontal shaft fixed at the rear end of the bucket body coupling.
5. The frame lifting adjustment mechanism is composed of a screw, a silk master and a turntable. The turntable is fixed on the top of the screw. The screw master and the frame are connected into an integral structure. The screw is screwed into the screw master. Insert the lower end into the screw end hole on the traction beam.
