Description

Technical field:

[0001] The utility model relates to an excavating shovel, in particular to an adaptive excavating shovel, belonging to the technical field of excavating shovels. Background technology:

[0002] The excavator shovel is one of the main working parts of the excavator. It is used for excavating, loading, and transporting soft rocks such as earth and stone. The excavator shovel plays an irreplaceable role in the entire operation process of the excavator. The working principle of the excavator shovel is to complete the excavation, loading, and unloading through the up and down movement of the excavator arm and the opening and closing of the bucket. In addition, the excavator shovel also has a certain sweeping ability, which can clean up the residues and weeds on the construction site to improve the construction efficiency.

[0003] When the excavator shovel is working, the length of the shovel teeth determines the area of ​​soil or rock that the excavator shovel can contact each time it digs. Longer shovel teeth mean a larger excavation area. Therefore, the excavator shovel can dig and move more materials per unit time, thereby improving the excavation efficiency. Most of the existing excavator shovels are of an integrated structure, and their shovel teeth are fixed on one side of the bucket and have a fixed length. When the excavator shovel excavates soil with higher hardness or lower humidity, the shovel teeth are subjected to greater force, and the swing amplitude increases during the operation, resulting in an increased risk of wear and damage to the shovel teeth themselves. For this reason, an adaptive excavator shovel is proposed. Utility model content:
