DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] Embodiment 1:

[0025] according to Figure 1-5 As shown, an improved excavator bucket comprises a bucket body 1, a bucket tip 4 and a fixing mechanism, wherein the fixing mechanism is used to connect the bucket body 1 and the bucket tip 4;

[0026] The surface of the bucket body 1 is fixedly connected to a connecting frame 2, the surface of the connecting frame 2 is connected to a connecting rod 3, the other end of the connecting rod 3 is connected to the excavator, and the bucket body 1 is designed to be wide at the top and narrow at the bottom;

[0027] The fixing mechanism includes a sliding cavity 5, which is provided in the bucket body 1 and is open at one end. A sliding shaft 7 is slidably connected in the sliding cavity 5, and a positioning shaft 8 is movably connected on the surface of the sliding shaft 7. A mounting block 9 is fixedly connected on the surface of the bucket tip 4. A mounting groove is provided on the surface of the bucket body 1 relative to the position of the mounting block 9. The positioning shaft 8 is "L"-shaped. A positioning groove is provided on the surface of the mounting block 9 relative to the position of the positioning shaft 8. A reinforcing block 6 is fixedly connected to the surface of the bucket tip 4 on one side where the mounting block 9 is provided. A notch is provided on the surface of the bucket body 1 relative to the side of the reinforcing block 6.

[0028] During operation, the bucket body 1 is mounted on the excavator through the connecting rod 3, and the road surface is excavated by the excavator. Because the diameter of this bucket is smaller than that of a general bucket, trenches can be excavated in a small construction range and a limited space, thereby greatly improving the excavation efficiency. After the bucket body 1 has been used for a long time, the bucket tip 4 at the end may have broken teeth. At this time, by sliding in a direction away from the bucket body 1, the sliding shaft 7 drives the positioning shaft 8 to disengage from the mounting block 9, so that the mounting block 9 can be disengaged from the mounting groove, and the bucket tip 4 can be replaced by the mounting block 9 in conjunction with the mounting groove. The practicality of the bucket body 1 can be improved by the separate design of the bucket body 1 and the bucket tip 4, because most buckets are of integrated design. When in use, gaps will appear that affect excavation. If the entire bucket is replaced, it will not be economical. The replaceable method can greatly reduce the cost of use, and the strength of the connection can be increased by the reinforcing block 6 to avoid the bucket tip 4 from breaking.

[0029] The sliding shaft 7 is slidably connected in the sliding cavity 5 through a spring, and a protective groove 13 is provided at the open end of the sliding cavity 5. A protective cover 12 is magnetically arranged in the protective groove 13, and the outer wall of the protective cover 12 is parallel to the outer wall of the bucket body 1, so that after the protective cover 12 is completely inserted into the protective groove 13, the outer wall of the protective cover 12 is flush with the outer wall of the bucket body 1, and the surface of the protective cover 12 is fixedly connected to a limit block;

[0030] During operation, the sliding cavity 5 can be shielded by the magnetic protective cover 12 to prevent soil from entering the sliding cavity 5 when the bucket body 1 is used for excavation. Over time, the sliding shaft 7 cannot slide, affecting the replacement of the bucket tip 4. At the same time, the protective cover 12 parallel to the outer wall of the bucket body 1 can improve the integrity of the bucket body 1 and avoid excessive wear. At the same time, the installation direction of the protective cover 12 can be limited by the limit block to avoid the wrong direction when the protective cover 12 is installed.

[0031] A thread groove 11 is provided in the sliding cavity 5, and a thread matching the thread groove 11 is also provided on one end surface of the sliding shaft 7 close to the thread groove 11, and a bevel 10 is provided on one end surface of the positioning shaft 8 inserted into the positioning groove. A sealing strip 18 is fixedly connected to the surface of the bucket tip 4, and a sealing groove is provided on the surface of the bucket body 1. During operation, after the bucket tip 4 is installed, the sliding shaft 7 is rotated so that the thread at the end of the sliding shaft 7 cooperates with the thread groove 11, and at the same time, the bevel 10 can make the bucket tip 4 fit more tightly, and at the same time, the sealing strip 18 can prevent mud from entering the groove.

[0032] A guide groove 15 is provided on the surface of the bucket body 1, and a guide block 14 is fixedly connected to the surface of the bucket tip 4. The surface of the guide block 14 has a rounded corner. During operation, the guide block 14 can improve the convenience of installing the bucket tip 4.

[0033] Embodiment 2:

[0034] like Figure 6 As shown, compared with Example 1, as another embodiment of the utility model, the connecting frame 2 and the connecting rod 3 are movably connected, and a protrusion 17 is fixedly connected to the surface of the connecting rod 3, and a slot 19 is provided on the surface of the connecting frame 2 corresponding to the position of the protrusion 17, and a pin hole is provided on the surface of the connecting frame 2, and a fixing pin 20 is inserted into the pin hole; when working, the bucket can be adapted to different excavators by cooperating with the pin hole through the fixing pin 20, thereby improving the applicability of the bucket, and at the same time, positioning through the protrusion 17 can improve the convenience during installation.
