Preferably, the hydraulic device comprises a hydraulic rod 6, a hydraulic station 7; the surface increasing wheel mounting frame is hinged with the hydraulic rod 6; the hydraulic station 7 controls the hydraulic lever 6.
Preferably, the surface increasing wheel mounting frame comprises a mounting fulcrum 41 and a surface increasing wheel bracket 42; one end of the surface increasing wheel bracket 42 is fixed on the mounting fulcrum 41 through hinge joint; the middle of the surface increasing wheel bracket 42 is connected and fixed with a rotating shaft seat of the surface increasing wheel 5; the other end of the face-increasing wheel bracket 42 is hinged with the hydraulic rod 6.
Preferably, the control system is a PLC control system.
The novel theory of operation of this experiment does: when the equipment normally operates, static friction force is generated between the transmission roller 1 and the conveying belt 3, the reverse force of the static friction force is the traction force of the conveying belt 3, and the conveying belt 3 starts to move under the action of the traction force, so that the material is driven to be transmitted; the rotation speed sensor 2 is used to measure the rotation speed of the driving drum 1, which is transmitted back to the control system and converted into the linear speed of the outer ring of the driving drum 1, and the tachometer wheel 8 is used to measure the running speed of the conveyor belt 3, which is transmitted back to the control system and compared with the linear speed of the outer ring of the driving drum 1, at which time, because of normal operation, the two are kept consistent or different within a predetermined range.
When the transmission roller 1 runs for a long time, the salient points on the surface of the transmission roller 1 are abraded, the friction force is reduced, the weight of each blanking cannot be uniformly controlled in actual production due to different weights of ores, when the weight is too heavy, the load is too large, and the reason causes the slippage of a conveying belt of a belt conveyor, the difference between the linear velocity of the outer ring of the transmission roller 1 and the velocity of the velocity measuring wheel 8 exceeds a preset range, and at the moment, the slippage of the belt conveyor can be judged; the control system automatically starts the hydraulic station 7, controls the hydraulic rod 6 to be pushed out, and the surface increasing wheel 5 moves upwards in a circular manner around the mounting fulcrum 41, so that the surrounding angle between the conveying belt 3 and the transmission roller 1 is increased, the tension of the return conveying belt 3 is increased, the traction force of the conveying belt 3 is increased, and the running speed of the conveying belt 3 is further increased; when the running speed of the conveying belt 3 and the linear speed difference value of the outer ring of the transmission roller 1 are within a reasonable range, the slip sign of the belt conveyor is eliminated, the control system automatically stops the work of the hydraulic station 7, the hydraulic rod 6 stops moving, the problem of shutdown and production stop of the belt conveyor due to slip is solved, and the production efficiency is effectively improved.
