[0019] Example 1
[0020] like Figures 1-5 As shown, the device includes a crushing wall body 1. Multiple positioning protrusions 4 are uniformly fixed to the outer side of the crushing wall body 1. Two sleeves 2 are provided on the outer side of the crushing wall body 1, and the two sleeves 2 are connected to the crushing wall body 1 via connecting components. To facilitate stone crushing, multiple crushing blocks 5 are uniformly fixed to the outer side of the sleeves 2. An eccentric drive mechanism 9 is provided on the inner side of the crushing wall body 1. A shearing plate 7 is provided on the inner side of the positioning protrusions 4. A spreading component is provided on the inner side of the crushing wall body 1 at a position corresponding to the shearing plate 7, for use in conjunction with the shearing plate 7. Both the positioning protrusions 4 and the shearing plate 7 are set at a 15-degree inclination. When the sleeves 2 rotate eccentrically, the impact force of the stone on the shearing plate 7 in the lateral direction can be reduced, thereby reducing wear on the shearing plate 7. The crushing blocks 5 are sloping irregular blocks. When crushing stone, the thicker end of the crushing block 5 squeezes and crushes the stone, thereby improving the wear resistance of the crushing block 5.
[0021] Through the coordinated structural design of the casing 2, crushing block 5, shearing plate 7 and spreading component, the crushing block 5 can crush the stone when the crushing wall body 1 is rotated eccentrically by the crushing wall eccentric drive mechanism 9. Compared with the traditional crushing wall method of crushing stone, this device effectively reduces the wear of stone on the crushing wall, thereby improving the service life of the device.
[0022] Example 2
[0023] like Figure 2 As shown, in order to facilitate the connection and fixation of the two shells 2 to the crushing wall body 1, the connecting assembly includes a connecting block 8, which is fixed at the top of the crushing wall body 1. A connecting plate 3 is fixed at the top of the shell 2 near the connecting block 8. The connecting plate 3 and the connecting block 8 are connected by a second connecting bolt 19. In order to improve the stability of the connection between the shell 2 and the crushing wall body 1, the lower outer side of the shell 2 is connected to the crushing wall body 1 by a plurality of first connecting bolts 6.
[0024] During installation, firstly, move the two housings 2 from the side to the outside of the crushing wall body 1, then fix the two connecting plates 3 and the connecting block 8 with the second connecting bolts 19, and finally connect the lower end of the housing 2 to the crushing wall body 1 with multiple first connecting bolts 6.
[0025] Example 3
[0026] like Figure 4 and Figure 5 As shown, the spreading assembly includes a rotating shaft 10, which is vertically arranged inside the eccentric drive mechanism 9 of the crushing wall. The top end of the rotating shaft 10 extends to the outer side of the top end of the eccentric drive mechanism 9 of the crushing wall. The rotating shaft 10 is rotatably connected to the eccentric drive mechanism 9 of the crushing wall. A connecting shaft 15 is fixed to the top end of the rotating shaft 10. In order to facilitate the rotation of the reciprocating threaded sleeve 11 when the connecting shaft 15 rotates, a reciprocating threaded sleeve 11 is provided at the top end of the connecting shaft 15. Limiting plates 16 are fixed at both the upper and lower ends of the reciprocating threaded sleeve 11. The connecting shaft 15 is fixedly connected to one of the limiting plates 16. A connecting moving seat 12 is threadedly connected to the outer side of the reciprocating threaded sleeve 11. Through the structural design of the reciprocating threaded sleeve 11, the connecting moving seat 12 can reciprocate along the axial direction of the reciprocating threaded sleeve 11. At the same time, the limiting plate 16 limits the connecting moving seat 12 to prevent the connecting moving seat 12 from disengaging from the reciprocating threaded sleeve 11.
[0027] To facilitate the connection between the connecting movable seat 12 and the shearing plate 7, a connecting rod 14 is provided at the position between the connecting movable seat 12 and the shearing plate 7. One end of the connecting rod 14 is rotatably connected to the first connecting seat 13, and the other end of the connecting rod 14 is rotatably connected to the accommodating connecting seat 17. The accommodating connecting seat 17 is fixedly connected to the shearing plate 7, and the first connecting seat 13 is fixedly connected to the connecting movable seat 12. The lower end of the shearing plate 7 is rotatably connected to the positioning protrusion 4 through the rotating seat 18.
[0028] During operation, when the rotating shaft 10 rotates, it drives the reciprocating threaded sleeve 11 to rotate through the connecting shaft 15. When the reciprocating threaded sleeve 11 rotates, it drives the connecting moving seat 12 to move along the axial direction of the reciprocating threaded sleeve 11. When the reciprocating threaded sleeve 11 moves, it drives the shearing plate 7 to move in an arc shape around the rotating seat 18 at one end near the connecting moving seat 12 through the connecting rod 14. While crushing the stone, it can squeeze and shear larger stones into smaller stones, which makes it easier for the crushing block 5 to crush them. It can also effectively reduce the occurrence of jamming and blockage of the device due to large stones during crushing, thus improving the practicality of the device.
[0029] Working principle: During installation, firstly, the two sleeves 2 are moved from the side to the outside of the crushing wall body 1. Then, the two connecting plates 3 and connecting blocks 8 are fixed by the second connecting bolts 19. Finally, the lower end of the sleeve 2 is connected to the crushing wall body 1 by multiple first connecting bolts 6. During operation, the external drive device first drives the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, the crushing wall body 1 rotates eccentrically through the crushing wall eccentric drive mechanism 9. When the crushing wall body 1 rotates, the sleeves 2 rotate simultaneously. Thus, the crushing blocks 5 fixed with the sleeves 2 cooperate with the external fixed cone to crush the stone. When the rotation... When the rotating shaft 10 rotates, it drives the reciprocating threaded sleeve 11 to rotate through the connecting shaft 15. When the reciprocating threaded sleeve 11 rotates, it drives the connecting moving seat 12 to move along the axial direction of the reciprocating threaded sleeve 11. When the reciprocating threaded sleeve 11 moves, it drives the shearing plate 7 to move in an arc shape around the rotating seat 18 through the connecting rod 14. Thus, the shearing plate 7 opens to crush the stone and squeezes and shears larger stones into smaller stones, which is convenient for the crushing block 5 to crush. It can also effectively reduce the occurrence of the device jamming and blocking due to the large size of the stone during crushing, thus improving the practicality of the device.
