The excavator bucket teeth is the terminal of the excavator working device. During the excavation operation, the excavator bucket teeth is the most loaded working part, which is a consumable part, especially in the stone construction environment, the excavator bucket teeth wear speed is extremely fast. The condition of the teeth is good or bad, in fact, it can directly affect the work efficiency and production cost of the excavator.
1.Choose the right type of excavator bucket teeth
In the process of use, the specific excavator bucket teeth type is selected according to the working environment. generally excavation, weathered sand, surface coal, etc. Use flat head excavator bucket teeth. For the hard rock with block shape, use the RC type of excavator bucket teeth, and the T-shaped excavator bucket teeth is generally used for the block coal seam. The TL tooth can increase the coal yield rate. In actual use, users often prefer general RC type bucket teeth. It is recommended that RC type teeth are not used in special cases. It is best to use flat head teeth.
Because the RC type bucket tooth is worn like a “fist” after a period of wear, it increases the excavation resistance and wastes power, while the flat mouth teeth always maintain a sharp surface during the wear process, reducing the excavation resistance and saving fuel.
2.Replace the bucket teeth in time
When the tip end portion of the tooth is worn more seriously, the force required for the excavator to cut in during the excavation work is inevitably greatly increased, thereby generating greater fuel consumption and affecting work efficiency. Therefore, when it is checked that the tooth loss is serious, it is necessary to replace the new tooth in time.
3.Replace the bucket teeth adapter in time
The wear of the adapter is also very important for the service life of the tooth of the excavator. It is recommended to replace the adapter after the toothed seat wears 10%-15%, because there is a large gap between the toothed seat and the tooth. The gap causes the matching of the tooth and the tooth holder to change with the force point, and the tooth is broken due to the change of the force point.
4. Daily inspection and fastening
In the daily maintenance work of the excavator, spend 2 minutes a day to check the bucket. The main inspection contents are: the bucket body is worn and cracked. If the degree of wear is serious, reinforcement should be considered. As for the crack of the bucket body, it should be repaired in time to avoid the length of the crack due to delayed maintenance, resulting in unmaintainable conditions. In addition, use the foot to kick the excavator bucket teeth and check if the excavator bucket is stable. If the
excavator bucket is loose, it should be tightened immediately.
