The concrete mixer will inevitably fail during use. For example, a collision sound is found during mixing, or there are problems during feeding. Let's take a look at the problem-solving contents of the feeding device of the concrete mixer.
There is collision sound during concrete mixing
Cause: the mixing shovel or scraper is loose or warped, resulting in collision with the mixing drum. Solution: fasten the connecting bolts of the mixing shovel or scraper, repair and adjust the gap between the mixing shovel, scraper and the cylinder wall.
The mixing shovel does not rotate properly, and the operation sound is abnormal
Cause: buffer spring of mixing device failed. The mixing shovel is stuck by large particles in the mixture. Excessive feeding and power overload.
Solution: replace the spring. Clear the material card of the game. Feed according to the specified feeding capacity.
Slurry leakage of discharge door during operation
Cause: the discharge door is not tightly closed. The residual adhesive around the discharge door is too thick.
Discharge method: adjust the bolts under the unloading base plate to make the unloading door tightly closed. Remove the remaining bonding materials.
The operation of the upper hopper is not stable
Cause: the feeding track is warped and uneven, and the hopper roller is in poor contact.
Discharge method: check and adjust the two rails to make them straight and parallel
When the upper hopper rises, it crosses the upper solstice point and damages the traction mechanism
Cause: automatic limit failure. The automatic limit baffle is deformed and does not work.
Solution: repair or replace the limit device. Adjust the limit baffle.
Slurry leakage at shaft end of mixer
The slurry leakage at the shaft end of the concrete mixer is caused by the damage of the floating seal of the mixer during long-time operation. The shaft end of concrete mixer is the part with concentrated stress. During the operation of concrete mixer, the stress on the shaft end is the largest, so the wear of parts is correspondingly large.
It is also important to maintain the concrete mixer in time and replace the seals in time. For more information, please visit our website at www.zkhntjbj.com Com consultation to understand!
