Abstract

The invention discloses an automatic belt tension regulating device of a coal feeder. The automatic belt tension regulating device is characterized by comprising a control assembly and a regulating assembly, wherein the regulating assembly comprises a reduction gear and a tightening roller, and one end of a tightening roller core shaft is provided with a sliding block; a main gear of the reduction gear is connected with a motor, a driven gear is connected with one end of a tightening rod, the other end of the tightening rod is arranged in a pair of tightening rod guide rails and connected with the sliding block at one end of the tightening roller core shaft, and the sliding block is arranged in the tightening rod guide rails; the moving direction of the tightening rod is perpendicular to the tightening roller core shaft; the control assembly comprises a tightening wheel and a proximity switch, and one end of the tightening roller core shaft is provided with a sensing block; the proximity switch related with the sensing block is connected with the motor through a relay. The automatic belt tension regulating device of the coal feeder is accurate, reliable, free of manual operation, and capable of automatically regulating belt tension of the coal feeder.

Description

technical field [0001] The invention relates to an automatic adjustment device for belt tension of a coal feeder, belonging to the technical field of coal feeder equipment. Background technique [0002] The belts of the coal feeder are made of rubber and have a certain degree of ductility. At the same time, when the coal feeder is running, the inside of the coal feeder is in a high temperature state. Therefore, when the coal feeder runs for a certain period of time, the belt of the coal feeder will inevitably be deformed and elongated, resulting in deviation and slippage. However, using the current manual adjustment belt tensioning device after manual observation to repeatedly adjust the belt is not timely, and due to the randomness of manual adjustment, the tare weight of the coal feeder will change significantly, which will affect the measurement accuracy; And every time the belt tension is adjusted, the coal feeder needs to be calibrated again. This is time-consuming an...
