Heavy type composite type buffer device used for belt conveyor

Abstract

The invention relates to a heavy-duty compound buffer device for a belt conveyor, which comprises a buffer roller device and a buffer bed device, and the buffer roller device and the buffer bed device are arranged at intervals. The buffer idler device includes a support base, and a buffer idler support beam is fixed between the support bases, and a left idler column and a right idler column are respectively fixed at both ends of the buffer idler support beam, and the left idler column The left buffer roller is installed obliquely between the buffer roller support beam, the right buffer roller is installed obliquely between the right idler roller column and the buffer roller support beam, and the middle part of the buffer roller support beam is installed horizontally. Roller. This composite buffer combines the advantages of the buffer roller and the buffer bed, has double buffering effects, effectively overcomes the traditional single-structure buffer device, and improves the buffering effect.

Description

technical field [0001] The invention relates to the field of buffer devices, in particular to a heavy-duty composite buffer device for belt conveyors. Background technique [0002] Belt conveyors are widely used in food, medical, wharf, mining and other fields in my country; belt conveyors have strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can easily implement programmed control and automatic operation. The belt conveyor is composed of conveyor belt, idler roller, rolling and driving, tensioning, redirection, loading, unloading, cleaning and other parts. [0003] The traditional loading part mainly uses buffer rollers before the buffer bed is used. It has been used for decades, but its design and working principle are likely to cause longitudinal and penetrating tearing of the conveyor belt, and because the buffer roller and the belt The impact contact method causes the material discharge port to be not tightly sealed, causin...

AI Technical Summary

Problems solved by technology

[0003] The traditional loading part mainly uses buffer rollers before the buffer bed is used. It has been used for decades, but its design and working principle are likely to cause longitudinal and penetrating tearing of the conveyor belt, and because the buffer roller and the belt The impact contact method causes the sealing of the blanking port to be not tight, causing the material to fall and accumulate, and it is easy to cause problems such as belt deviation. The use of buffer rollers not only brings a lot of maintenance costs and waste of production capacity of the belt.

[0005] 1. The supporting roller has poor cushioning capacity and cannot absorb the strong impact force of falling materials well, and it is easy to smash the supporting roller, causing the hidden danger of longitudinal tearing of the belt

[0006] 2. The supporting frame of the support roller is easily deformed by the impact of the material frequently, the roller is easy to fall off, and the upright support seat of the support roller is easy to hang or tear the belt

[0007] 3. The support roller and the conveyor belt are in line contact, and the space between the two rollers is suspended, so it is easy for the material or other sharp hard objects to penetrate the belt between the two rollers, and get stuck between the non-feeding openings of the rollers, resulting in belt failure. Longitudinal tear tape

[0008] 4. The belt between the two rollers is easy to sag, which makes the belt in the area of ​​the discharge port wavy, which makes the sealing of the discharge port poor, resulting in material scattering and environmental pollution

[0009] 5. The surface of the support roller is inelastic, and the surface is easy to adhere to the material after long-term operation, which will wear the belt, and in severe cases will cause the belt to deviate

[0010] 6. The rotating bearing of the supporting roller is impacted for a long time, and the bearing and seal are easy to fail, resulting in inflexible or non-rotating roller body rotation and wear on the belt surface

[0013] 2. The buffer strip is severely worn, glued and stripped;

[0014] 3. The buffer bed cannot satisfy the conveying capacity in the use of the belt conveyor with a large conveying capacity, which seriously increases the friction;

[0015] 4. In the case of many loading points, it is extremely inconvenient to use, increasing friction and increasing the load of the driving part
