[0031] In this example, the connecting shaft 3 is arranged on one side between the mounting frames 2, then the hook bucket shaft body 4 penetrates the mounting frames 2 and the connecting shaft 3, so that the hook body 1 and the connecting shaft 3 are rotationally connected, after the hook body 1 and the connecting shaft 3 are connected, the gap between the mounting frame 2 and the connecting shaft 3 is wrapped by the dustproof ring 5, the remaining gap on the outer side of the hook bucket shaft body 4 is protected from dust, the dust in the gap between the connecting shaft 3 and the hook bucket shaft body 4 is reduced, thereby avoiding the wear of the outer side of the hook bucket shaft body 4, and prolonging the service life of the hook bucket shaft body 4;

[0032] And the dustproof ring 5 is connected through the fastening bolt 7, so that when the dustproof ring 5 needs to be replaced due to wear, it can also be more conveniently disassembled, and at the same time, the dustproof ring 5 is avoided from being replaced by disassembling and replacing the entire hook bucket shaft body 4, thereby increasing the applicability of the whole in use. EMBODIMENT

[0033] As Figure 1 , Figure 3 and Figure 4The technical scheme shown is to solve the problem of loosening of the fastening bolt 7 due to slight vibration during long-term use: the excavator bucket shaft with the dust ring structure discloses a limiting mechanism, the front end of the connecting block 6 is provided with the limiting mechanism, the limiting mechanism comprises a fixed frame 8, a limiting frame 10 is installed on the left side of the fixed frame 8 through a connecting spring 9, the limiting frame 10 is arranged on the outer side of the fastening bolt 7, the cross section of the limiting frame 10 is in the shape of an inverted “L”, the inner side of the limiting frame 10 is in close contact with the outer side of the fastening bolt 7, the bottom end of the limiting frame 10 is in sliding connection with the inner side of the fixed frame 8, and the side of the limiting frame 10 and the fixed frame 8 constitute an elastic structure through the connecting spring 9.

[0034] In this case, when the fastening bolt 7 passes through the connecting block 6 to lock and fix the dust ring 5, the position of the limiting frame 10 is adjusted so that the inner side of the limiting frame 10 can be in close contact with the outer side of the fastening bolt 7, and the height of the fastening bolt 7 is limited. When the connecting block 6 is threadedly connected with the fastening bolt 7, the fastening bolt 7 will not be loosened due to frequent vibration. At the same time, the elastic force of the connecting spring 9 can assist the resetting of the position of the limiting frame 10, so that the limiting frame 10 can be flexibly adjusted in position according to different requirements, increasing the flexibility during use.

[0035] The shape of the limiting frame 10 can better fit the outer side of the fastening bolt 7 and limit its position. At the same time, the limiting frame 10 and the fixed frame 8 are in sliding connection, so that the movement of the limiting frame 10 will not be stuck. Embodiment

[0036] As Figure 1 , Figure 5 and Figure 6 The technical scheme shown is to solve the problem of slipping off the edge of the hook bucket shaft body 4 during use: the excavator bucket shaft with the dust ring structure discloses an anti-falling mechanism, the right side of the hook bucket shaft body 4 is in close contact with a limiting plate 11, and the inside of the limiting plate 11 is provided with an anti-falling mechanism for preventing slipping, the anti-falling mechanism comprises a mounting block 12, the mounting block 12 is clamped and connected to the right side inside the hook bucket shaft body 4, the right side of the mounting block 12 is in close contact with the left side of the limiting plate 11, the left side of the limiting plate 11 is provided with an extrusion plate 18 through a connecting rod 17, the left side of the extrusion plate 18 is in close contact with the right side of the mounting frame 2, the front and rear ends of the mounting block 12 are both provided with a fixed box 13, the inside of the fixed box 13 is provided with a clamping block 15 through a reset spring 14, and the outside of the hook bucket shaft body 4 is provided with a clamping groove 16 matched with the clamping block 15, the outside of the clamping block 15 and the inside of the fixed box 13 are in sliding connection, and the clamping block 15 passes through the fixed box 13 and extends to the outside of the clamping groove 16.

[0037] In this example, the mounting block 12 is inserted into the right side of the hook shaft body 4 so that the limiting plate 11 can fit against the right side of the hook shaft body 4. The angle of the mounting block 12 is adjusted so that the locking block 15 and the locking groove 16 engage with each other, so that the connecting rod 17 on the left side of the limiting plate 11 can push the extrusion plate 18, and at the same time, the extrusion plate 18 can block the remaining gap of the hook shaft body 4, thereby effectively reducing the amount of dust entering the gap between the connecting shaft 3 and the hook shaft body 4.

[0038] The return spring 14 inside the fixed box 13 can push out the card block 15 and engage it with the card slot 16. When the limiting plate 11 needs to be disassembled, pressure is applied to the card block 15, so that the return spring 14 at the bottom of the card block 15 is stressed and shortened in length. At the same time, the card block 15 separates from the card slot 16, so that the limiting plate 11 loses its limit and can be quickly disassembled.
