Description

 Split dental caries

 The present invention relates to construction, construction machinery, mining, metallurgy, port storage and transportation equipment, and more particularly to a split tooth for a tumbling loader and a hopper feeder.

Background technique

 At present, in the process of coal mining and roadway excavation, there are problems of faster mining and excavation speed, and slower transportation speed, which leads to the inability of the two processes to operate synchronously. Therefore, transportation becomes a bottleneck in coal mining production, which seriously restricts production efficiency. The above problems need to be resolved urgently. In material handling equipment, currently used loaders include rear dump bucket loaders, disc star wheel loaders, crab claw loaders, claw loaders, bucket loaders, side dump shovel Bucket loaders and skimmers, among them, are widely used by skimmers. These equipments alleviate the contradiction between mining, fast excavation and slow transport speed during the loading of materials after excavation.

 However, the above devices all have problems such as low work efficiency and uneven loading. Taking the skimmer as an example, the skimmer is diverted by a reciprocating hopper, and the hopper is driven by a hydraulic cylinder. The moving speed of the hydraulic cylinder is slow, resulting in low charging efficiency, large volume of the bucket, and one bucket for one bucket, resulting in uneven feeding, which is unfavorable to the subsequent transportation system. In order to solve the above problems, rolling materials are generated. The loader, the rolling pick-up loader is dip by a rotating drum with a molar tooth, which is continuous feeding, feeding evenly and quickly. However, the molars are directly fixed on the rotating drum, and the fixed end of the molar is long and integral with the tooth tip. When the tooth tip encounters resistance, the arm of the fixed end is long, and the fixed part is rotated. The damage force of the drum is large. If the fixing force is increased, the fixed weight must be increased, resulting in waste of materials and an increase in running load, so that the entire rolling weight is large and the energy consumption is large.
