Heavy duty apron feeder is generally divided into heavy duty, medium and light three, is commonly used in the factory feeding equipment. Heavy duty apron feeder system continuous feeding machinery, widely used from storage bin to crushing, transportation and other machinery for uniform continuous feeding: Medium heavy duty apron feeder system intermittent feeding machinery, widely used from storage bin to crushing, transportation and other machinery for uniform intermittent feeding: Heavy duty apron feeder is an auxiliary equipment for transportation machinery.
A heavy duty apron feeder is designed, which comprises two support plates arranged in opposition, a plate conveying assembly is arranged between the two support plates, a chain transmission mechanism is arranged at both ends of the plate conveying assembly, and an active sprocket assembly is arranged at one end of the chain transmission mechanism. The other end of the chain drive mechanism is provided with a driven sprocket assembly, the lower part of the plate conveying assembly is provided with a shaft that rotates synchronically with the driven sprocket assembly, the shaft is connected with two support plates through the first bearing, the outer surface of the rotating shaft is provided with a brush, the brush is in contact with the bottom of the plate conveying assembly, the bottom of the brush is provided with a guide plate, it can clean the surface adhesion of the connected plate unit and increase the load bearing capacity of the connected plate unit of the heavy duty apron feeder.
However, the above device lacks a fine material separation device, because in the aggregate crushing, there are many raw wool mixed with many fine materials, if these fine materials enter the crushing production line through the feeder, it is bound to affect the crushing efficiency and screening effect of the whole line.
We are designed to provide a heavy duty apron feeder that separates fine materials to address the issues raised in the background technology above. The heavy duty apron feeder for separating fine material comprises a frame, the frame is provided with a movable bearing seat on the left side before and after the frame, the movable bearing seat is connected with a driven shaft between the movable bearing seat, the frame is provided with a fixed bearing seat on the right side before and after the frame, and the fixed bearing seat is connected with a drive shaft between the fixed bearing seat. The driven shaft and the drive shaft are provided with two sprockets, the sprocket is connected with a rail chain, the rail chain is provided with a mounting slot, the top of the rail chain is provided with a number of track plate, the mounting slot is provided with a fixed component fixed connection with the track plate, the adjacent track plate between a certain gap, the leakage hopper is fixed in the frame, the leakage hopper is located between the upper and lower sides of the rail chain, the middle of the leakage hopper is raised, the bottom of the frame is provided with a roller assembly, the right end of the frame is provided with a motor base, the motor base is provided with a three-phase asynchronous motor, the right side of the three-phase asynchronous motor is provided with a speed reducer, the three-phase asynchronous motor and the reducer are connected through a belt and a belt pulley, and the output shaft of the reducer is connected with the drive shaft through a coupling. The fixing assembly includes hex head bolts, spring washers and hex nuts. The bottom of the track plate is provided with a scraper, and the bottom of the scraper corresponds to the shape of the raised part of the leakage hopper.
The top of the heavy duty apron feeder is symmetrically provided with a guard plate support, and the guard plate support is provided with a guard plate.
The left end of the frame is arranged with a pull rod, the thread on the pull rod is connected with a nut, the nut and the frame is arranged with a spring, the left end of the spring is connected with a spring gland, the spring gland is on the right side of the nut, the spring gland is sliding connected with the pull rod.
1. Narrow the track plate through the rail chain, track plate and leakage hopper, so that there is a gap between the track plate for fine materials to leak into the leakage hopper, and separate the fine materials before the raw wool materials enter the production line to break, improve the crushing production efficiency of the production line and improve the crushing and screening effect:
2. Through the set scraper, the bottom of the scraper corresponds to the shape of the raised part of the drain hopper, which is convenient to clean the surface of the raised part of the drain hopper and avoid the fine material sticking to the surface of the raised part and not entering the drain hopper.
