With the rapid development of the construction machinery industry, excavators are an important earthwork construction equipment, its work efficiency, and cost control have become the focus of the industry. Among them, the bucket tooth is the terminal part of the excavator working device and its performance directly affects the overall performance and production cost of the excavator. In the following, a number of recommendations will be made for the optimization strategy of bucket teeth, aiming to improve the efficiency of excavator operation and reduce maintenance costs.

1. Choose the appropriate bucket tooth type

Bucket teeth in the use of the process to see the working environment, to determine the specific type of bucket teeth, general excavation, weaved sand, coal, and so on to use flat head bucket teeth. Excavating block hard rock with RC bucket teeth, excavating block coal generally with TL bucket teeth, TL bucket teeth can improve the coal block rate. In actual use, users often like general RC bucket teeth, it is recommended not to use RC bucket teeth in special cases, and it is better to use flat-head bucket teeth, because RC bucket teeth are worn for a period of time before, like "fist" to increase the mining resistance and waste power and the flat mouth bucket teeth always maintain a sharp surface in the wear process, reduce the mining resistance, and save fuel.

2. Replace the bucket teeth in time

When the top part of the bucket tooth is worn seriously, the strength required by the excavator in the excavation operation will be greatly increased, resulting in greater fuel consumption and affecting work efficiency. Therefore, it is necessary to replace the new bucket teeth in time when the bucket teeth loss is more serious.

3. Replace the tooth base in time

The wear condition of the tooth seat is also very important to the service life of the excavator bucket teeth. After the tooth seat is worn out by 10%-15%, it is recommended to replace the tooth seat, because there is a large gap between the tooth seat and the bucket teeth with excessive wear, so that the bucket teeth and the tooth seat are matched the force point has changed, and the bucket teeth are broken because of the change of the force point.

4. Daily check fastening

In the daily maintenance of the excavator, spend 2 minutes a day checking the bucket. The main inspection content is: the bucket body is the degree of wear and whether there are cracks, if the degree of wear is serious, it should be considered for reinforcement. If the bucket body has cracks, it should be welded in time to avoid the delay of maintenance and increase the length of the crack, resulting in a situation that cannot be maintained. In addition to kicking the teeth of the digging bucket with the foot, check whether the ruler is stable if the teeth are loose, it should be immediately fastened.

5. Replace the position after wear

Practice has proved that in the process of using the excavator bucket teeth, the bucket teeth outside the bucket is 30% faster than the inside of the bucket teeth. It is suggested that after a period of time, the bucket teeth should be inverted inside and out.

6. Pay attention to driving methods

The driving method of the excavator, the driver is also very key to improving the utilization rate of the bucket teeth. The driver of the excavator should try not to collect the bucket when lifting the arm. If the driver lifts the arm while collecting the bucket, the operation will make the bucket teeth receive an upward traction force, so that the bucket teeth are torn from the top of the bucket, so as to tear the bucket teeth. Some excavator drivers often push too hard in the action of amplifying the arm sending the forearm, and "knocking" the bucket quickly to the rock or force the bucket to fall on the rock, which will break the bucket teeth, or easy to crack the bucket, and break the big arm.

The excavator driver should pay attention to the Angle operation of excavation during the operation. The bucket teeth should be perpendicular to the working face when digging down, or the inclination Angle is not greater than 120 degrees, to avoid breaking the bucket teeth due to excessive inclination Angle. Also, pay attention not to swing the digging arm around in the case of large resistance, which will make the bucket teeth and tooth seat break due to excessive force on the left and right, because the mechanical design principle of most types of bucket teeth do not consider the left and right force design.
