There are five reasons for blocking:
1, the hoist starts to feed or the feed inlet is uneven;
2. The hopper belt slips;
3, the feed inlet feed too much;
4. Large or fibrous foreign objects enter the box;
5. The discharge port is not smooth.
For the above five reasons, we give the corresponding solutions as follows:

2. Because the belt is too loose, the belt will be tensioned by the tensioner. If the belt is too loose, you need to cut the belt.
3. Similar to the first case, we only need to control the feed speed to achieve the goal.
4, through the access door next to the base to clean up the fibrous, massive and other foreign bodies of the base or box.
5. clear the entrance.
Fault 2: Too much material is returned.
There are three reasons for the failure of excessive material return:
1, the linear speed of the traction assembly is too fast, resulting in insufficient unloading;
2. The distance between the hopper and the discharge port is too large;
3. The discharge port is not smooth.
For the above three reasons, Zhengzhou Honglin Machinery gives the following solutions:
1, adjust the motor speed.
2. Adjust the distance between the discharge port and the discharge port.
3. Clear the drain or drain pipe.
Fault 3: The equipment has abnormal sound.
There are four reasons, namely:
The hopper bolt or U-shaped buckle is loose, or the hopper, bolt and U-shaped buckle fall off;
2, materials mixed with metal and other debris into the hoist;
3. Clearance between traction members (including belts, chains, plate chains, etc.). ) and the box is too small, leading to collision;
4. Traction components (including belts, chains, plate chains, etc. ) is too loose or falls off due to long-term use, so that the hopper collides with the box.
The corresponding solutions are as follows:
1. Open the access door on the side of the base, tighten the loose bolts, and tighten the fallen hopper, bolts and U-shaped buckle. If the hopper and U-shaped buckle are damaged, replace them in time.
2, open the manhole, clean up the metal and other debris into the box.
3. Open the upper cover of the crane head from the crane maintenance platform and adjust the position between the hopper and the discharge port.
4. Adjust the tensioner to make the tension of the traction device moderate. If the traction device is too loose and exceeds the adjustment range of the tensioner, proper cutting is needed.
