Description

Technical Field

[0001] The present application relates to the technical field of excavators, and in particular to an excavator bucket that is easily replaceable. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig materials above or below the surface of the machine and load them into a transport vehicle or unload them to a stockpile. The materials it digs are mainly soil, coal, silt, and pre-loosened soil and rocks. The bucket is the component of the excavator that directly contacts the soil. The excavator can use mechanisms such as the bucket arm and the oil cylinder to drive the bucket to perform excavation work. Existing excavator buckets are usually arc-shaped solid buckets, and a number of bucket teeth are set at the front end of the bucket, so that the earth can be fully excavated and loaded.

[0003] However, the existing excavator bucket still has some defects during use: the bucket teeth will wear out and fail after long-term use and need to be replaced, and the existing bucket teeth are connected by pins. When disassembling, the pins need to be taken out manually, and then the bucket teeth are replaced, which is troublesome to operate. Especially when replacing a large number of bucket teeth, the staff need to replace them one by one, which will waste a lot of time and thus affect work efficiency. Utility Model Content

[0049] Embodiment 2

[0050] On the basis of the first embodiment, the limiting mechanism 3 further includes:

[0051] See also Figure 1-Figure 5 , Figure 9-11, a rotating assembly 4, a rotating assembly 4 is movably provided at one end of the limiting mechanism 3, and the rotating assembly 4 is located at the end of the limiting mechanism 3 away from the bucket tooth 2, which is used to improve the discharge efficiency of earthwork materials.

At this time, the limit block 31 will no longer limit and fix the bucket teeth 2. The staff can replace the worn bucket teeth 2 one by one according to the needs, that is, fix the bucket teeth 2 along the fixing plate 14. The hole and the fixing groove of the bucket body 11 are pulled out, and then the new bucket tooth 2 is pushed into the fixing plate 14 along the fixing groove and the fixing hole. Finally, the limit block 31 and the limit plate 32 are put back in place, and the limit bolt 33 is used to fix the limit mechanism 3, thereby realizing the limit fixation of the bucket tooth 2. In summary, the device changes the connection method of the original bucket tooth 2, so that the bucket tooth 2 does not need to rotate the pin shaft multiple times one by one to realize disassembly and installation, effectively improving the convenience of replacing the bucket tooth 2, thereby saving time and improving the working efficiency of the device.

[0054] When the bucket is loaded with earth and materials, the rotating plate 42 is fitted with the bottom end of the bucket body 11 due to the gravity of the materials. When the bucket is unloading earth and materials, the rotating plate 42 is rotated due to its own gravity, thereby pushing the earth and materials to fall and improving the discharge efficiency of the materials.
