Description

Technical Field

[0001] The utility model belongs to the technical field of a device for bearing material impact when transferring and dropping materials on a belt conveyor, and particularly relates to a buffer device with adjustable angle. Background Art

[0002] The buffer device is installed below the belt at the transfer and drop point of the belt conveyor. Due to the height difference between the upper and lower joints, the falling material will create an impact force on the conveyor belt, affecting the service life of the conveyor belt and the safe operation of the equipment. If the material is stuck between the two rollers, it will cause longitudinal tearing and damage to the conveyor belt. Currently, most belt conveyor systems are equipped with a drop buffer device, but conventional buffer devices cannot achieve a good buffering effect. The buffer device is prone to deformation and wear quickly, shortening the service life of the conveyor belt. At the same time, the angle of the existing buffer device is mostly fixed, while the corresponding belt conveyor groove angle has many specifications. Therefore, buffer devices with different dedicated angles are required for corresponding use, which is costly. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides a buffer device with adjustable angle, which has a simple structure and is easy to operate and use.

[0004] The technical solution of the utility model to solve the above-mentioned technical problems is as follows: A buffer device with adjustable angle includes a base frame, a buffer bar bracket, a buffer bar, an adjustable plate, a connecting plate and an eccentric adjustment plate, wherein the connecting plate is fixedly connected to the base frame, the adjustable plate is installed between the left and right connecting plates, the eccentric adjustment plate is installed on one side of the connecting plate, the buffer bar bracket is fixedly connected to the adjustable plate, and a plurality of buffer bars are installed on the buffer bar bracket. A circular hole is provided on the adjustable plate, and an oblique long hole is provided on the connecting plate. Bolts are passed through the circular hole on the adjustable plate, the eccentric hole on the eccentric adjustment plate and the oblique long hole on the connecting plate to fix the adjustable plate and the eccentric adjustment plate to the connecting plate.

[0005] Furthermore, the adjustable plate is provided with a plurality of L-shaped grooves, and the buffer bar and the buffer bar bracket are connected to the L-shaped grooves of the adjustable plate through T-shaped bolts to prevent the buffer bar from moving.

[0006] Furthermore, the connecting plate is fixedly connected to the base frame by welding.

[0007] Furthermore, the buffer strip is a high-molecular polyethylene high-elastic rubber strip with flame retardant and antistatic properties.

[0008] Preferably, the eccentric adjustment plate is a regular decagon, and the groove angle of the buffer device can be changed from 25° to 35° by adjusting the eccentric adjustment plate, thereby better buffering the impact of falling materials on the conveyor belt.

[0009] Compared with the existing technology, the beneficial effects of the present invention are as follows: the overall structure of the buffer device and the flame-retardant and antistatic high-molecular polyethylene high-elasticity rubber buffer strips are used to cushion the impact of falling materials on the conveyor belt, protecting the conveyor belt, preventing damage caused by material impact, and preventing the conveyor belt from deviation. By adjusting the angle of the buffer device, the buffer device can adapt to belt conveyors with different groove angles, which is more adaptable and reduces costs. The angle of the buffer device groove can be adjusted simply by controlling the eccentric adjustment plate, which is more convenient and can ensure that the angle will not shift automatically after adjustment. The structure is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
