[0023] The first embodiment of this utility model is as follows:

[0024] A novel bucket includes a body 1 for scooping material, and a quick-installation assembly is provided on the back of the body 1. The quick-installation assembly includes a seat plate for limiting quick-change, a quick-connect rod 6 for cooperating with the seat plate to connect the bucket to the quick-change, and a locking assembly for locking the quick-connect rod 6.

[0025] In other embodiments, a back plate 4 is welded to the back of the main body 1, and the quick-installation assembly and ear plate are both welded onto the back plate 4. This embodiment is described in the form of installation without a back plate 4, where the base plate and quick-installation assembly are directly installed on the back of the main body 1.

[0026] The lug plate includes a cylinder lug plate 3 located at the center of the back of the main body 1 for connecting to the hydraulic cylinder, and a stick lug plate 2 located on both sides of the back of the main body 1 for connecting to the stick. The cylinder lug plate 3 is located above the stick lug plate 2, forming a height difference, and is connected to the stick and hydraulic cylinder in a conventional manner through the stick lug plate 2 and the cylinder lug plate 3.

[0027] In special circumstances where it is necessary to temporarily change the bucket, the bucket can be connected to the quick-change device through quick-installation components to speed up the connection. There are two sets of quick-installation components, located on both sides of the back of the bucket. The two sets of quick-installation components are symmetrically arranged and used to connect with the quick-change device.

[0028] The seat plate includes an upper seat plate 14 and a lower seat plate 5 that are horizontally fixed on the back of the main body 1. There is a gap between the upper seat plate 14 and the lower seat plate 5 to accommodate the quick-change. Corresponding positions of the upper seat plate 14 and the lower seat plate 5 are provided with through holes. The quick-connect rod 6 passes through the through holes on the upper seat plate 14 and the lower seat plate 5 from top to bottom. The upper seat plate 14 and the lower seat plate 5 limit the vertical position of the quick-change. The quick-connect rod 6 is inserted into the through hole on the quick-change to achieve fixation, so that the quick-change is fixedly connected to the bucket body 1.

[0029] The locking assembly includes a core rod 12 hinged to the quick-connect rod 6. The core rod 12 is a two-section structure with different diameters. The diameter of the upper section of the core rod 12 is smaller than that of the lower section. The lower section of the core rod 12 is hinged to the quick-connect rod 6. A spring 7 and a sliding seat 13 are sleeved on the upper section of the core rod 12. The inner diameter of the spring 7 is smaller than that of the lower section of the core rod 12, which can abut against the spring 7. A nut for limiting the maximum sliding distance of the sliding seat 13 is engaged at the upper end of the core rod 12. The sliding seat 13 can slide up and down in the upper section of the core rod 12. When it slides down, it will compress the spring 7. When it slides up to the position of the nut, it can no longer slide up.

[0030] The locking assembly also includes a handle, which consists of a long arm 10 and a short arm 8. The long arm 10 is the hand-held part. Since its length is greater than that of the short arm 8, the lever arm of the long arm 10 is greater than that of the short arm 8. According to the lever law, a smaller force is needed to rotate it. An obtuse angle is formed between the long arm 10 and the short arm 8. When the long arm 10 rotates to the horizontal position, the short arm 8 has already rotated from the vertical position and tilted to the other side. A shaft hole is provided at the junction of the long arm 10 and the short arm 8. A rotating shaft 11 is fixedly provided at the upper end of the back of the body 1. The rotating shaft 11 passes through the shaft hole, allowing the handle to rotate around the rotating shaft 11. The other end of the short arm 8 is hinged to the sliding seat 13.

[0031] A limiting plate 9 is fixedly installed on the back of the main body 1 near the pivot 11 to limit the maximum angle of the handle rotation. When the quick-change needs to be connected, first hold the long arm 10 and turn the handle. Pull the quick-connect rod 6 upward through the core rod 12 so that its lower end moves to a position flush with the lower surface of the upper seat plate 14. At this time, place the quick-change between the upper seat plate 14 and the lower seat plate 5. Then turn the handle in the opposite direction. The quick-connect rod 6 moves downward through the core rod 12, passing through the quick-change and the lower seat plate 5. During this process, the spring 7 will first be compressed to its shortest length and then extend to a certain length. When the long arm 10 is in a horizontal position, the short arm 8 has rotated past the line where the quick-connect rod 6 is located, rotated to the other side and abutted against the limiting plate 9. At this time, the sliding seat 13 compresses the spring 7. The spring 7 applies an upward torque to the short arm 8 through the sliding seat 13. At this time, the short arm 8 will be stuck on the limiting plate 9.
