04. Daily inspection and tightening

In the daily maintenance work of the excavator, take 2 minutes to check the bucket every day. The main inspection contents are: the degree of wear of the bucket body and whether there are cracks. If the degree of wear is more serious, reinforcement should be considered. If there is a crack in the bucket body, it should be repaired by welding in time to avoid increasing the length of the crack due to the delay in repair and causing impossible maintenance. In addition, kick the excavator bucket teeth with your feet to check whether the teeth are stable. If the teeth are loose, they should be tightened immediately.

05. Change position after wear

Practice has proved that during the use of excavator bucket teeth, the outermost tooth of the bucket wears 30% faster than the innermost tooth. It is recommended to reverse the position of the inside and outside of the bucket teeth after a period of use.


06. Pay attention to driving method

The driving method of the excavator driver is also very important to improve the utilization of the excavator bucket teeth. The excavator driver should try not to retract the bucket when lifting the boom. If the driver raises the boom while retracting the bucket, this operation will The excavator bucket teeth are subjected to an upward traction, so that the bucket teeth are torn apart from the top, thereby tearing the bucket teeth. Special attention should be paid to the coordination of the action during this operation. Some excavator drivers often use too much force in the action of expanding the arm 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, or It is easy to crack the digging bucket and damage the big and small arms.

The excavator driver should pay attention to the excavation angle operation during the operation. When the bucket teeth are digging down perpendicular to the working surface, or the camber angle is not greater than 120 degrees, to avoid breaking the bucket teeth due to excessive inclination. Also be careful not to swing the digging arm left and right under the condition of large resistance, which will cause the bucket teeth and gear seat to break due to excessive force on the left and right, because the mechanical design principle of most models of excavator bucket teeth does not consider the force on the left and right. design.
