[0027] Please refer to Figure 3-4, the protective structure 2 includes a protective component 21. Sliders 22 are fixedly connected to the upper and lower sides of the front and rear of the protective component 21. A first sliding rod 23 is movably connected to the inner wall of the slider 22. A first spring 24 is sleeved on the left side of the outer wall of the first sliding rod 23. The left and right ends of the first sliding rod 23 are fixedly connected to the left and right sides of the inner wall of the chute 12. The protective component 21 includes a groove body 211. Trapezoidal arc plates 212 are fixedly connected to the upper and lower sides on the right side of the groove body 211. Arc-shaped scraping plates 213 are fixedly connected to the front and rear sides on the right side of the groove body 211. Limiting grooves 214 are opened on the upper and lower sides of the inner wall of the groove body 211. A rotating shaft 215 is movably connected to the inner wall of each of the two limiting grooves 214. A roller 216 is fixedly connected to the end of the two rotating shafts 215 close to each other;

[0028] Through the cooperation of the slider 22 and the first sliding rod 23, the protective component 21 of the protective structure 2 can slide inward in the chute 12, so that the protective component 21 can shrink inward when encountering a stone during the excavation of materials, thereby providing the best protection effect. The first spring 24 provides a certain elastic force for the first sliding rod 23 to ensure that the protective component 21 can quickly reset when the bucket tooth 1 passes by a stone. The roller 216 can reduce the friction during the excavation of the bucket tooth 1 and improve the overall working efficiency.

[0029] Please refer to Figure 5 , the tooth tip structure 3 includes a tooth tip block 31. An installation groove 32 is opened at the bottom of the tooth tip block 31. A partition plate 35 is fixedly connected to the middle position of the inner wall of the installation groove 32. Circular moving holes one penetrating to the inside are opened on the left and right sides of the tooth tip block 31. A pressing rod 33 is movably connected to the inner wall of the circular moving hole one. Movable blocks 34 are fixedly connected to the ends of the two pressing rods 33 close to each other. Circular moving holes two penetrating to the left are opened on the front and rear sides of the right side of the movable block 34. A second sliding rod 36 is movably connected to the inner wall of the circular moving hole two. Second springs 37 are sleeved on the sides of the outer walls of the left and right second sliding rods 36 close to each other.

[0030] When the tooth tip block 31 is damaged due to the bucket tooth 1 encountering a hard object during excavation or when different types of tooth tips need to be replaced according to work requirements, by pressing the pressing rod 33, the movable block 34 moves along the outer wall of the second sliding rod 36 and squeezes the second spring 37, and the rectangular insertion block 39 disengages from the rectangular slot 14, enabling the removal of the tooth tip block 31. In addition, through the installation groove 32 and the partition plate 35 at the bottom of the tooth tip block 31, the tooth tip block 31 has a certain buffer space when being impacted, further protecting the stability and durability of the tooth tip block 31.

[0031] Working principle:

[0032] The protection component 21 of the protection structure 2 can slide inward in the chute 12 through the cooperation of the slider 22 and the first sliding rod 23, enabling the protection component 21 to contract inward when encountering a stone during the excavation of materials, thereby providing the best protection effect. The first spring 24 provides a certain elastic force for the first sliding rod 23 to ensure that the protection component 21 can quickly reset when the bucket tooth 1 passes by a stone. The roller 216 can reduce the friction force during the excavation of the bucket tooth 1 and improve the overall working efficiency. The trapezoidal arc plate 212 and the arc-shaped scraper 213 fixedly connected to the right side of the trough body 211 can further prevent damage to the side of the bucket tooth 1 and clean the outer wall of the roller 216 at the same time, improving the practicability of the device;

[0033] When the tooth tip block 31 is damaged due to the bucket tooth 1 encountering a hard object during excavation or when different types of tooth tips need to be replaced according to work requirements, by pressing the pressing rod 33, the movable block 34 moves along the outer wall of the second sliding rod 36 and squeezes the second spring 37, and the rectangular insertion block 39 disengages from the rectangular slot 14, enabling the removal of the tooth tip block 31. In addition, through the installation groove 32 and the partition plate 35 at the bottom of the tooth tip block 31, the tooth tip block 31 has a certain buffer space when being impacted, further protecting the stability and durability of the tooth tip block 31.
