According to the analysis of the information and the introduction of the prototype, it is economical and the direction of selection to select a heavy-duty apron feeder with a small width, a large speed and a large capacity when the selection of the heavy-duty apron feeder allows. With the development of large and medium-sized mines, the heavy-duty apron feeder as one of the mining equipment should also be developed to large and medium-sized. In order to facilitate the selection and control of the selection, a standardized series of products should be developed. In the design of the machine, it should be simple and novel, easy to install and use. The drive device should develop a speed reducer with a large speed ratio and large torque, and the type should be a direct-angle type, or a low-speed high-torque hydraulic motor. Minimize the machine weight and cross-sectional size to facilitate process layout. The chain adopts a crawler chain. The chain plates can be welded chain plates or cast chain plates according to the needs. Chain plate structure can choose double arc or single arc. The horizontal dimension of double-arc chain plates is smaller than that of single-arc chain plates, but the bolts connecting the chain plates have to contact the material, and it is more troublesome to install and disassemble the bolts; while the lateral dimensions of single-arc chain plates are larger than that of double-arc chain plates. , But the connecting chain plate bolts do not touch the material, and the chain plate is easier to assemble and disassemble. The supporting chain plate structure should develop a combined supporting structure of rollers and slide rails. The tail tension should develop a tension structure with a buffer spring. The transmission part connection should develop a keyless connection. The receiving section should develop a structure with a buffer device according to the needs. In short, the development of heavy-duty apron feeders that are large and medium-sized, large-capacity, new in structure, wide in application, low in price, and suitable for various process selection needs is the direction of development.
