Heavy duty apron feeder is widely used in industrial sectors such as mining, gold treatment, building materials and coal. The machine is mainly placed under the silo and funnel with fixed bin pressure, and all kinds of large capacity heavy materials are uniformly and continuously transported to various crushing, screening and transportation equipment in a short distance. The existing heavy duty apron feeder mainly has a frame, the two ends of the frame are respectively provided with the driving wheel driven wheel, the driving wheel between the chain, the chain is firmly connected with the plate, the plate is used to transport all kinds of materials. In order to tighten the chain, the equipment should be equipped with a tensioning device. Under normal circumstances, the tension device is installed on the side of the driven wheel, and the tension device adjusts the shaft position of the driven wheel through the spring and nut, so that the chain 2 maintains a certain tension. The chain and plate located between the driving wheel and the driven wheel are supported by the upper roller device and the lower roller device. The working principle of the existing heavy duty apron feeder: Under the action of the external power device, the driving wheel rotates, and drives the chain and the driven wheel. In this way, the chain and plate move in a circle around the driving wheel and the driven wheel to realize the conveying of materials. The existing wheel support device, between which are two existing wheel support shaft, the existing wheel support shaft length is short, and the two existing wheel support shaft is located on the same axis line, one end of the existing wheel support shaft is installed in the middle of the hollow wheel through the bearing, and the other end of the existing wheel support shaft is fixed on the frame. When the existing wheel is mounted, the plate is installed on the chain, and the two ends of the plate are supported on the wheel, and finally provide support to the chain.
The main shortcomings of the existing wheel support device are: The wheel support device is arranged in the lower part of the frame, arranged in several groups on both sides, and is in a suspended installation state. The wheel support device mainly supports the return conveyor chain, and the force it bears is relatively small. Because the return chain is not smooth during operation, for example, large materials pass unevenly through the silo, and the return chain and the wheel support device are in line contact, the final force acting on the wheel support device is not smooth, and there is an impact. The built-in bearing of the wheel support device is easily damaged under the action of unstable forces. When the bearing is damaged, the wheel support device can not run smoothly, the return chain is easy to produce a large jump, resulting in the equipment can not run smoothly, while increasing the operating load of the equipment, serious damage to the wheel support device, the formation of safety hazards.
Aiming at the shortcomings in the prior art, it provides a heavy duty apron feeder wheel support device which is not easy to damage. In order to realize the wheel support device, wherein: The middle of the wheel support device is a wheel support shaft, two wheels are symmetrically arranged on the wheel support shaft through the bearing gland, the bearing is limited in the wheel support shaft through the bearing gland, and both ends of the wheel support shaft are firmly connected with the equipment frame. Further, an axle seat is provided, through which both ends of the wheel support shaft are fixedly connected with the heavy duty apron feeder frame.
