Description

Technical Field

[0001] The utility model relates to the technical field of chains, in particular to a chain bucket conveyor chain resistant to a strong dust environment. Background Art

[0002] The chain bucket conveyor chain is a chain used for mechanical transmission between the motor and the drum of the chain bucket conveyor on the chain bucket conveyor. The chain is generally a metal chain link or ring, and is mostly used for mechanical transmission and traction. It has the advantages of high load-bearing capacity, applicability to harsh working environments, high transmission efficiency, and small force acting on the shaft. Therefore, it is widely used on chain bucket conveyors.

[0003] Currently, when the chain bucket conveyor chain is in use, during the long-term rotation of the rollers on the chain, due to the vibration of the device, the position of the rollers may shift, thereby affecting the service life of the chain bucket conveyor. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a chain bucket conveyor chain resistant to a strong dust environment, which solves the problem that during the long-term rotation of the rollers on the chain bucket conveyor chain, due to the vibration of the device, the position of the rollers may shift, thereby affecting the service life of the chain bucket conveyor.

[0005] The above technical object of the utility model is achieved through the following technical solutions:

[0007] By adopting the above technical solution, by setting the limiting component, after the rotating roller on the chain is installed on the pin shaft, the position of the rotating roller on the pin shaft is limited through the limiting component, preventing the position of the rotating roller from shifting and affecting the use of the chain bucket conveyor.

[0008] Preferably, the limiting component includes: telescopic grooves respectively opened on both sides of the pin shaft, a limiting block is arranged inside the telescopic grooves, a telescopic rod is movably sleeved inside the telescopic grooves, the telescopic rod is fixedly connected with the limiting block, a spring is arranged outside the telescopic rod, and a limiting sleeve is fixedly installed at one end of the telescopic rod.

[0009] By adopting the above technical solution, by setting a limit sleeve, after the rotating roller is installed on the pin shaft, the two ends of the rotating roller are limited by the limit sleeves on both sides of the pin shaft. When the rotating roller vibrates and causes position deviation, the limit sleeve compresses and absorbs part of the vibration through the spring in the telescopic groove and then releases the deformation to buffer the vibration, preventing the position of the rotating roller from deviating due to the vibration of the device and improving the service life of the chain bucket conveyor.

[0010] Preferably, a turntable is fixedly installed on the inner wall surface of the limit sleeve, a plurality of installation grooves are formed on one side of the turntable, and balls are rotatably installed inside the installation grooves.

[0011] By adopting the above technical solution, by setting the balls, after the limit sleeve limits the rotating roller, when the rotating roller rotates, the friction between both sides of the rotating roller and the limit sleeve is reduced through the balls on the turntable, ensuring the lubricity of the rotating roller.

[0012] Preferably, a sound insulation ring is arranged inside the limit sleeve.

[0013] By adopting the above technical solution, by setting the sound insulation ring, when the balls on the turntable rotate, noise will be generated, and at the same time, certain noise will also be generated when the rotating roller rotates. The sound insulation ring reduces the noise generated by the rotation of the rotating roller.

[0014] Preferably, a sealing ring is fixedly adhered to the outside of the sound insulation ring.

[0015] By adopting the above technical solution, by setting the sealing ring, there is a gap between the rotating roller and the pin shaft. In an environment with a lot of dust, it may enter the inside of the rotating roller. After a long time, the rotation lubricity of the rotating roller will decline. The sealing ring is beneficial to improving the sealing performance between the rotating roller and the pin shaft.

[0016] Preferably, one end of the telescopic rod is fixedly installed with a connecting bolt, a connecting hole is formed on one side of the limit block, and the connecting bolt is threadedly connected with the connecting hole.

[0017] By adopting the above technical solution, by setting the connecting bolt, when it is necessary to replace some parts of the chain, the staff can loosen the limit sleeve to drive the telescopic rod and the limit block to disengage, so as to facilitate disassembly and maintenance.

[0018] In summary, the main beneficial effects of the present utility model are as follows:

[0019] By setting a limit sleeve, after the rotating roller is installed on the pin shaft, the two ends of the rotating roller are limited by the limit sleeves on both sides of the pin shaft. When the rotating roller vibrates and causes a position offset, the limit sleeve compresses and absorbs part of the vibration through the spring in the telescopic groove, and then deforms and releases to buffer the vibration, preventing the position of the rotating roller from shifting due to the vibration of the device and improving the service life of the chain bucket conveyor.

[0020] By setting balls, after the limit sleeve limits the rotating roller, when the rotating roller rotates, the balls on the turntable reduce the friction between both sides of the rotating roller and the limit sleeve, ensuring the lubrication of the rotating roller. Description of the Drawings

By setting the limiting component, after the rotating roller 4 on the chain is installed on the pin shaft 3, the position of the rotating roller 4 on the pin shaft 3 is limited by the limiting component, preventing the position deviation of the rotating roller 4 and affecting the use of the chain bucket conveyor.

By setting the limiting sleeve 9, after the rotating roller 4 is installed on the pin shaft 3, the two ends of the rotating roller 4 are limited by the limiting sleeves 9 on both sides of the pin shaft 3. When the rotating roller 4 vibrates and causes position deviation, the limiting sleeve 9 compresses and absorbs part of the vibration through the spring 8 in the telescopic groove 5 and then deforms and releases it to buffer the vibration, preventing the position of the rotating roller 4 from deviating due to the vibration of the device and improving the service life of the chain bucket conveyor. A connecting bolt 13 is fixedly installed at one end of the telescopic rod 6, a connecting hole 12 is opened on one side of the limiting block 7, and the connecting bolt 13 is threadedly connected with the connecting hole 12. By setting the connecting bolt 13, when it is necessary to replace some parts of the chain, the staff can loosen the limiting sleeve 9 to drive the telescopic rod 6 to disengage from the limiting block 7, thus facilitating disassembly, installation and maintenance.

[0029] Reference Figure 3 , Figure 4, a turntable 14 is fixedly installed on the inner circumferential wall surface of the limit sleeve 9. A plurality of mounting grooves 15 are formed on one side of the turntable 14. A ball 16 is rotatably installed inside the mounting groove 15. By providing the ball 16, after the limit sleeve 9 limits the rotating roller 4, when the rotating roller 4 rotates, the friction between both sides of the rotating roller 4 and the limit sleeve 9 is reduced by the balls 16 on the turntable 14, ensuring the lubricity of the rotating roller 4.
