Apron feeder is generally divided into heavy, medium and light three, is commonly used in concentrator feeding equipment. In the existing technology, apron feeder comprises a frame, both ends of the frame are respectively provided with a guide rail, the guide rail is respectively sliding with a bearing seat, the bearing seat between the rotation of the rear drive shaft, the rear drive shaft is fitted with a tail wheel. At present, the tail shock absorber applied in apron feeder has defects such as large transmission noise, large vibration of the whole machine, and can not properly adjust the tension of the conveyor chain. The purpose is to make up for the shortcomings of the existing technology, to provide a apron feeder tail shock absorber, its transmission noise is small, the whole machine vibration is small, can moderately adjust the tension of the conveyor chain. The apron feeder tail shock absorber is realized through the following technical solution: the apron feeder tail shock absorber comprises a frame, the two ends of the frame are respectively provided with a guide rail, the guide rail is respectively sliding with a bearing seat, the bearing between the seat rotation is installed with a rear drive shaft, which is characterized in that: the inner side of the frame end plate is provided with a support, the support is fixed on the nut; the screw rod is rotated in the nut, and the inner end of the screw rod is pressed against the corresponding bearing seat, and the outer end passes through the frame end plate and extends out of the end plate: the screw rod is arranged between the frame end plate and the support. The tail shock absorber of apron feeder is characterized in that a threaded hole is arranged at the corresponding part of the lead screw on the bearing seat, and the inner end of the lead screw is screwed into the threaded hole. By adding the spring mechanism, the tension force of the conveying chain can be appropriately adjusted, and the vibration of the whole machine is small, the transmission noise is small, the operation is stable, and the service life becomes: the transportation capacity of the utility model is improved.
Apron feeder is a kind of heavy-duty feeding device, because of its good impact resistance, it is widely used in coal, mining, cement and other industries, because it needs strong impact resistance, so it must have a good shock absorber. Especially in the apron feeder tail loading position is carrying a lot of impact. So our company developed this damping device to reduce the impact of apron feeder.
