Description

Automatic deviation correcting belt conveyor Technical Field The invention relates to an automatic deviation correcting belt conveyor, and belongs to the technical field of belt conveyors. Background The belt conveyor is more used in the solid waste garbage treatment process so as to meet the requirement of larger conveying throughput. However, the components of the solid waste are complex, so that the deviation of the belt frequently occurs, and the normal feeding is affected. In order to prevent the belt from deviating, the upper carrier roller of the belt conveyor mostly adopts V-shaped carrier rollers, namely two symmetrical side carrier rollers and a middle positive carrier roller, and the middle part of the belt is formed into a plane and two side inclined planes when the belt passes through the carrier rollers. But the belt is carrying solid useless rubbish in-process, because of the mass distribution who bears the weight of the material is uneven, causes the increase of running resistance, belt off tracking frequently, and the belt off tracking can cause the material leakage seriously, consequently need often shut down and carry out manual work and rectify, reduce belt operating time, adjust belt and clearance work intensity of labour is big, increases maintainer's work load and maintenance cost. Especially when inspection personnel find untimely, can cause tearing belt, broken axle accident, there is the potential safety hazard, change belt, the frequent maintenance cost of main shaft increases. For realizing preventing belt off tracking, the lower part setting of current belt anti-off tracking device is at the channel-section steel support, inboard fixedly connected with connecting rod at the channel-section steel support, the inboard of connecting rod is opened there is the slide rail, the inboard fixedly connected with fixed block in top of channel-section steel support, the bottom fixedly connected with two play axle motors of fixed block, two play axle motors drive first screw rod and second screw rod rotation for the first dead lever and the second dead lever of its connection are to opposite direction removal, are convenient for adjust the position of first dead lever and second dead lever, first dead lever and second dead lever respectively with respective cylinder bearing roller fixed bolster connection, and cylinder bearing roller on the cylinder bearing roller fixed bolster is used for supporting the belt. The belt deviation preventing mechanism can adjust the position of the belt through the position of the motor control fixing rod, so that the belt has certain automatic deviation correcting capability, but a set of electric screw rod driving mechanism is required to be arranged, the structure is complex, and the bearing capacity of the belt conveyor is limited because the cylindrical carrier roller on the upper part of the belt conveyor is vertical, so that the belt deviation preventing mechanism is not applicable to places with larger conveying throughput. Secondly, because this belt mechanism of rectifying rectifies to the belt of bearing the weight of the side, because the belt material lays can't guarantee evenly distributed, consequently need shut down at the time and rectify, and influence conveying efficiency.
