[0002] Excavators are widely used in the field of engineering construction, such as road opening, trenching, and demolition, which can greatly improve work efficiency. They are usually equipped with different attachments for different operations, but the bucket is still the main workhorse. Conventional buckets have a small volume and can only be used to dig soil, sand, or solid objects smaller than the bucket during construction. The digging range is small. In actual construction, objects larger than the bucket volume or with strange shapes are often encountered. Conventional buckets cannot dig such objects, so it is necessary to stop work and replace the fixture, which is time-consuming and labor-intensive. Common similar devices on the market mostly use a fixed center distance, and the parameters of excavators of the same level vary greatly. Therefore, the fixed center distance cannot match excavators of the same level from different manufacturers. Therefore, a targeted modification device is designed.

[0003] The prior art has the following problems:

[0004] The existing bucket has a relatively simple overall structure and a small bucket volume. It is generally only suitable for digging soil, sand or solid objects smaller than the bucket, and has a small digging range. At the same time, similar devices commonly seen on the market mostly use a fixed center distance, which cannot match excavators of the same level from different manufacturers, resulting in certain limitations in their use during work.

[0014] 1. A bucket clamp has a complete mechanical and hydraulic structure, is connected to the excavator through an upper connecting shaft, does not require welding, does not require modification of the excavator, is easy to operate, and does not affect the strength of the excavator arm; by setting the bucket body and the movable jaw for use in conjunction, the bucket can be used alone for digging, or the bucket and the movable jaw can be used together to clamp and remove larger objects, which can save working time and improve versatility; by designing a safety valve group on the cylinder assembly, sudden loosening after the oil pipe is broken is avoided, which has high safety and prevents personal injury; by setting the bucket body to be fixed to the excavator arm as a whole, it can be completely retracted, and the thumb clamp will not affect the normal use of the excavator.

[0015] 2. This bucket clamp is designed with an eccentric sleeve on the upper connection. The eccentric sleeve is rotated to change the axis center distance, which can match different excavators within a range and further improve the versatility of the equipment. The bucket and the movable jaw are set as a movable and detachable connection, which can facilitate the replacement of bucket teeth, improve the wear resistance of easily worn positions and the convenience of maintenance. The bucket body is designed with a drain port to give the bucket a drainage function, reduce excess energy consumption, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
