Ways to extend the service life of bucket teeth of imported excavator parts

1. Practice has proved that during the use of excavator bucket teeth, the outer bucket teeth of the Liugong excavator accessories bucket * wear 30% faster than the inside *. It is recommended that the inside and outside of the bucket teeth should be reversed after a period of use.

2. The bucket tooth depends on the working environment during the use process to determine the specific bucket tooth type. Generally, flat-head bucket teeth are used for soil excavation, weathered sand, and coal. RC type bucket teeth are used for digging massive hard rocks, and TL type bucket teeth are generally used for digging massive coal seams. TL bucket teeth can increase the rate of coal lump production.

In actual use, users often like general-purpose RC type bucket teeth. It is recommended that RC type bucket teeth should not be used under special conditions. It is easy to use flat-head bucket teeth. Because RC type bucket teeth wear out for a period of time, they will become bigger like a fist. Excavation resistance wastes power, while the flat-mouth bucket teeth always maintain a sharp surface during wear, which reduces excavation resistance and saves fuel.

3. The driving method of the excavator driver is also very important for improving the utilization of the bucket teeth. The excavator driver should try not to retract the bucket when lifting the boom. If the driver raises the boom, the bucket is retracted. It will cause the bucket teeth to be subjected to an upward traction, so that the bucket teeth will be torn apart from the top, thereby tearing the bucket teeth. This operation requires special attention to the coordination of the action.

Some excavator drivers often use too much force in the action of expanding and sending the forearm, and quickly "knob" the bucket against the rock or force the bucket against the rock, which will break the bucket teeth. Maybe simply knock the bucket with cracks and knock the big and small arms.

4. The wear condition of the gear seat of Kobelco excavator parts is also very important to the service life of the bucket teeth of the excavator. The gear seat is worn out by 10%-15% later, it is recommended to replace the gear seat. There is a large gap between the seat and the bucket teeth, which changes the fit between the bucket teeth and the tooth seat and the force point, and the bucket teeth crack due to the change of the force point.

5. The excavator driver should pay attention to the point of view operation during excavation, try to grasp it when excavating, the bucket teeth are perpendicular to the working surface when digging down, and the camber angle is not more than 120 degrees to prevent the bucket teeth from breaking due to excessive inclination. .

Also be careful not to swing the excavating arm left and right under the condition of large resistance, which will cause the bucket teeth and gear seat to crack due to excessive force on the left and right sides. Due to the mechanical planning principle of most types of bucket teeth, the left and right forces are not considered planning.
