Heavy duty apron feeder, widely used in mining, gold, building materials and coal and other industrial sectors. The machine is mainly used under the silo and funnel with a certain bin pressure, to transport a variety of large bulk weight materials in a short distance to a level of crushing, screening and transportation equipment, especially in the initial crushing more suitable. It is not only suitable for handling coarse grained materials, but also suitable for fine grained materials. It can complete heavy work in harsh environments, and has greater adaptability to changes in material particle size composition, temperature, viscosity, frost, rain and snow effects or ice forming materials. The feeding amount is uniform and reliable, the machine can be installed horizontally or tilted, and the maximum angle of upward transportation is 23.
Heavy duty apron feeder is the power of the motor, through the coupling and reducer drive sprocket shaft rotation through the sprocket teeth and chain pin mesh, drag the chain plate for continuous linear movement. The chain plate is supported by the supporting wheel and the supporting wheel installed on the frame, and the chain and sprocket are engaged correctly by adjusting the tension device to complete the purpose of conveying materials. The heavy duty apron feeder is mainly composed of a driving device, a chain plate device, a tensioning device and a spindle device. Frame. Support wheel. Sprocket. Its main characteristics are described as follows:
The driving device is composed of a motor, a coupling, a direct-alternating reducer, a planetary reducer, a torque rod, a locking disc, and other parts. The device is a vertical axis fulcrum floating type, the spindle is set in the output shaft of the planetary reducer, and the two are connected through the locking disc. It is characterized by light weight without foundation and large speed ratio. Due to the floating fulcrum, the additional bending moment caused by the installation error to the shaft is reduced, the service life of the drive shaft is improved, and the disassembly is convenient.
The chain plate device is composed of groove plate, chain joint, etc. The groove plate is a single arc lap joint type and is welded by low-alloy steel plate. High strength, wear resistance, no leakage. The chain link is the crawler chain (tank chain) of the bulldozer produced by a special manufacturer, which is characterized by a small pitch error and smooth movement, high strength, and large tension without lubrication.
The tensioning device is a screw rod tensioning mechanism, which is mainly composed of a shaft, two supporting wheels, both ends of the rolling bearing, bearing seat, composite spring, and tensioning screw and other parts. The heavy duty apron feeder is fixed on the shaft, and the two ends of the shaft are equipped with double row spherical roller bearings and bearing seats, which are installed on both sides of the frame and slide back and forth between the slide rails. The tension device is used to tighten and adjust the horizontal position of the chain. Ensure that the chain tightness is appropriate to make it run smoothly, and the supporting wheel plays the role of guiding and supporting the chain plate. By adjusting the tension screw, the tension of the two chains is uniform. When the chain plate is suddenly impacted by the material, the composite spring can play a buffer role to protect the chain plate and other components from damage.
