[0030] Embodiment 1:

[0031] Please refer to Figure 1-Figure 2 A bucket for an excavator comprises a digging hand 1, both sides of an outer end of the digging hand 1 are fixedly connected with a mounting plate 2, a plurality of shovel blocks 3 are fixedly connected with the bottom of the digging hand 1 away from the mounting plate 2, and the plurality of shovel blocks 3 have the same spacing, a reserved groove is provided on the inner side of the bottom of the digging hand 1, an extension component 4 is installed on the inner side of the reserved groove, and a protection component 5 is installed on the inner end of the reserved groove away from the shovel block 3.

[0032] The digging hand 1 can be installed by setting the mounting plate 2 and then used normally;

[0033] At the same time, the extension assembly 4 can be provided to allow operation to be performed in a smaller space when necessary;

[0034] At the same time, by providing the protection component 5, a certain protection effect can be played on the extension component 4, thereby reducing the impact of the vibration generated by the bucket during operation on the extension component 4.

[0035] Embodiment 2:

[0036] This embodiment 2 is used to further disclose the specific structure of the extension component 4 on the premise of the above embodiment. By coordinating the extension component 4 with the structure in the above embodiment, the extension component 4 is arranged inside the bucket, so that when the extension component 4 is needed in a smaller space, the installation and retraction of the extension component 4 can be avoided, thereby improving work efficiency.

[0037] The excavator bucket provided in Example 1 is further optimized. Specifically, Figure 3-Figure 4 As shown, the extension assembly 4 includes a motor 6 and a threaded rod 7. The motor 6 is arranged at one end of the inner side of the reserved groove away from the shovel block 3, and the output end of the motor 6 is fixedly connected to the threaded rod 7.

[0038] The extension component 4 also includes a movable transverse plate 8, an extrusion block 9 and a movable vertical plate 10. The outer side of the threaded rod 7 is threadedly connected to the movable transverse plate 8, and the movable transverse plate 8 is clearance-matched with the inner side of the reserved groove. The two sides of the movable transverse plate 8 away from the motor 6 are fixedly connected with the extrusion blocks 9, and the adjacent sides of the two extrusion blocks 9 are inclined. The outer side of the threaded rod 7 is threadedly connected to the movable vertical plate 10, and the two sides of the movable vertical plate 10 close to the end of the movable transverse plate 8 are provided with limiting grooves, and the movable vertical plate 10 is arranged at the end of the movable transverse plate 8 away from the motor 6, and the movable vertical plate 10 is clearance-matched with the reserved groove. The end of the movable vertical plate 10 away from the movable transverse plate 8 extends to the outside of the reserved groove and is fixedly connected to one of the shovel blocks 3.

[0039] The extension component 4 also includes a fixed plate 11, a sliding block 12 and a sliding rod 13. The fixed plates 11 are fixedly connected to both sides of the reserved groove away from the end of the motor 6. The sliding block 12 is arranged on the outside of the fixed plate 11, and the sliding block 12 and the limiting groove are plug-in and limited. The two sliding blocks 12 are arranged at an angle on the sides away from each other, and are extrusion-fitted with the inclined surface of the extrusion block 9. A movable groove is opened on the inside of the sliding block 12, and the fixed plate 11 and the movable groove are clearance-fitted. The sliding rod 13 is fixedly connected to the inside of the sliding block 12, and the sliding rod 13 and the inner side of the fixed plate 11 are clearance-fitted.

[0040] The extension assembly 4 also includes a spring 14. The spring 14 is arranged on the outer side of the sliding rod 13 away from the movable vertical plate 10. One side of the spring 14 is fixedly connected to the fixed plate 11, and the other side of the spring 14 is fixedly connected to the inner side of the movable groove.

[0041] Specifically: by turning on the motor 6, the threaded rod 7 can be driven to rotate inside the reserved groove, so that the movable horizontal plate 8 and the movable vertical plate 10 threadedly connected with the threaded rod 7 can be driven to move horizontally inside the reserved groove. When the threaded rod 7 drives the movable vertical plate 10 to move toward the end away from the motor 6, the movable vertical plate 10 can be extended out of the inside of the reserved groove and drive one of the shovel blocks 3 to extend synchronously, so that the operation can be performed in a smaller space;

[0042] When the moving cross plate 8 and the moving vertical plate 10 move synchronously, the moving cross plate 8 can drive the extrusion blocks 9 on both sides to move synchronously. When the extrusion blocks 9 move to the outside of the sliding plug blocks 12, they can squeeze the sliding plug blocks 12 by the inclined setting with the outside of the sliding plug blocks 12, so that the sliding plug blocks 12 can be pushed toward the limit grooves provided in the moving vertical plates 10, and the limit grooves provided in the moving vertical plates 10 are plugged and limited, so that the moving vertical plates 10 can be further positioned. When the moving vertical plates 10 drive the shovel blocks 3 to work, the moving vertical plates 10 can be supported to a certain extent, and the motor 6 and the threaded rod 7 can be protected at the same time.

[0043] At the same time, the space of the limit groove is slightly larger than the sliding block 12, so that space can be reserved for the sliding block 12 to move out of the inner side of the limit groove;

[0044] The setting of the sliding rod 13 can stabilize and support the movement of the sliding block 12;

[0045] At the same time, when the sliding block 12 moves, the inner side of the sliding block 12 can squeeze the spring 14. After the moving vertical plate 10 drives one of the shovel blocks 3 to complete the operation, the threaded rod 7 can be driven to rotate in the opposite direction by turning on the motor 6, so that the moving cross plate 8 and the moving vertical plate 10 move to the side close to the motor 6. At the same time, the sliding block 12 will lose the squeezing effect of the squeezing block 9. At this time, the elastic effect of the spring 14 after squeezing the inner side of the sliding block 12 can drive the sliding block 12 to be pushed to the side away from the moving vertical plate 10, so that the sliding block 12 can cancel the squeezing limit cooperation with the moving vertical plate 10, and the moving vertical plate 10 can move to the inner side of the reserved groove.

[0046] Embodiment 3:

[0047] This embodiment 3 is used to further disclose the specific structure of the protection component 5 on the premise of the above embodiment. By cooperating with the protection component 5 and the structure in the above embodiment, it is possible to achieve a protection operation around the motor 6, thereby reducing the impact of the vibration generated by the bucket during operation on the extension component 4.

[0048] The excavator bucket provided in Example 1 and Example 2 is further optimized. Specifically, Figure 5 As shown, the protection component 5 includes a concave plate 15, a fixing plate 16 and an arc-shaped elastic plate 17. The concave plate 15 is fixedly connected to one end of the inner side of the reserved groove away from the shovel block 3. The inner side of the concave plate 15 wraps the motor 6, and the inner side of the concave plate 15 is fixedly connected to the motor 6. The top and bottom of the concave plate 15 are both provided with fixing plates 16, and the two fixing plates 16 are both fixedly connected to the top and bottom of the inner side of the reserved groove. A plurality of arc-shaped elastic plates 17 are provided between the two fixing plates 16 and the concave plate 15, and the plurality of arc-shaped elastic plates 17 have a buffering effect on the fixing plates 16 and the concave plate 15.

[0049] Specifically: when the digging hand 1 is subjected to external impact or collision during operation, the vibration generated can be transmitted to the inner side of the fixing plate 16 inside the reserved groove;

[0050] The material of the arc-shaped elastic plate 17 can be set to copper or other elastic and harder materials. Through the elastic setting of multiple arc-shaped elastic plates 17, it can buffer and absorb energy when the vibration generated by the fixed plate 16 is transmitted to the concave plate 15. At the same time, through the setting of the concave plate 15 wrapping the motor 6, the impact of the vibration on the motor 6 can be reduced, thereby reducing the impact of the vibration generated by the digging hand 1 during operation on the work of the extension component 4.
