[0002] In recent years, with the acceleration of urbanization in my country, the amount of engineering construction in the fields of transportation, construction, water conservancy projects, etc. has increased. The market demand for construction machinery has increased dramatically across the country, especially the demand for hydraulic excavators has continued to grow, and the requirements for the use functions of hydraulic excavators have become more and more. In the domestic hydraulic excavator industry, the market application field of hydraulic excavators is relatively wide, mainly relying on the diversity of hydraulic excavator working accessories. According to different working conditions and needs, hydraulic excavators need to be equipped with different accessories. Different professional accessories are required for different work needs. However, the switching of multiple accessories often requires the excavator to stop working and be manually replaced. Although the existence of quick-change devices will improve the replacement efficiency, it also increases the cost.

[0003] There are two types of buckets on the market. The first type of bucket has a screening structure at the bottom (refer to the utility model patent with authorization announcement number CN213682280U). When shoveling some specific materials, the soil powder or fine particles mixed around the materials will leak from the screening structure, thereby achieving the purpose of screening the materials. The second type of bucket has a closed structure at the bottom (refer to the utility model patent with authorization announcement number CN212612701U), which is suitable for digging or loading on one side of a ditch or restricted space without the need to screen materials. Generally speaking, the above two types of buckets cannot be used interchangeably. The usual practice is to disassemble and replace the above two types of buckets on the excavator. This not only requires the investment of funds to purchase two types of buckets, but also the disassembly and replacement process is relatively cumbersome. Summary of the invention

A plug-in plate 16 is fixedly installed on the inner side of the upper end of the bucket part 1, and a plurality of support rods 25 are evenly fixedly installed on the inner side of the lower end. A plug-in rod 26 is fixedly installed on the inner end of the support rod 25. When the plug-in plate 16 is inserted into the sliding cavity 6, the plug-in rod 26 is synchronously slid and inserted into the plug-in groove 23, so that the two bucket parts 1 can move on the left and right sides of the bucket part 2, thereby changing the width of the bucket body, which is convenient for the bucket to be used in different excavation environments.

[0032] The inner ends of the two bucket parts 1 are provided with docking grooves 22, and a sieve plate 27 or a bottom plate 29 is inserted into the docking grooves 22. A reinforcing frame 28 is fixedly installed on the outer end of the sieve plate 27, and a reinforcing frame 2 30 is fixedly installed on the outer end of the bottom plate 29. The left and right ends of the reinforcing frame 1 28 or the reinforcing frame 2 30 are inserted into the two docking grooves 22, and the sieve plate 27 or the bottom plate 29 is located at the upper end of the connecting rod 3 and the support rod 25.
