[0034] Embodiment 2

[0035] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0036] In order to enable the stone crusher to achieve the function of suppressing dust, this embodiment provides the following design:

[0037] The dust collecting assembly 4 includes a dust collecting plate 41, a dust filter 42 and a dust cleaning door 43. The dust collecting plate 41 is arranged on the side of the discharge hopper 13. The dust filter 42 is arranged on the bottom and side of the dust collecting plate 41. The dust cleaning door 43 is arranged on the front and rear sides of the dust collecting plate 41.

The dust removal box 51 is arranged on the inner side of the box body 11, and the dust removal box 51 is located below the stone crushing mechanism 2. A fan 52 is arranged inside the dust removal box 51. A dust inlet 55 is provided at one end of the dust removal box 51, and a dust outlet plate 53 is provided at the other end of the dust inlet 55. A dust outlet 54 is provided inside the dust outlet plate 53, and the dust outlet 54 is arranged downwardly inclined. The fan 52 arranged inside the dust removal box 51 can generate suction at the dust inlet 55. When the crushed stone falls, the flowing air can suck the dust into the dust removal box 51. The dust outlet 54 arranged downwardly inclined can facilitate the delivery of dust-laden air into the inner side of the dust collecting plate 41.

[0039] The working principle and use process of this utility model:

[0040] When using:

[0041] First, the stone to be crushed is put into the crushing chamber 12. At this time, the driving device 22 in the crushing mechanism 2 drives the movable jaw plate 23 to move continuously. The movable jaw plate 23 cooperates with the fixed jaw plate 21 to continuously squeeze the stone in the crushing chamber 12, so that the stone is crushed and falls;

[0042] During the crushing process:

[0043] When the stones are large, the movable jaw plate 23 and the fixed jaw plate 21 have difficulty in bearing force and the stones slip, the motor 33 in the auxiliary crushing mechanism 3 drives the driving rod 35 to rotate, and the rotating driving rod 35 drives the auxiliary crushing rod 32 to move in the box body 11 through the threaded driving plate 34, and the moving auxiliary crushing rod 32 pushes the stones in the crushing chamber 12, adjusts the position of the stones, and facilitates the crushing of the stones;

[0044] When discharging:

[0045] When the crushed stones fall into the discharge hopper 13, the fan 52 in the dust removal component 5 starts working, and the air will enter the dust removal box 51 from the discharge port 14 and the dust inlet 55. The flowing air will take away the dust in the crushed stones. The air will carry the dust through the dust filter 42 of the dust collecting component 4, so that the dust will remain on the inside of the dust filter 42. In this way, the dust flying when the stones are crushed can be reduced, which will affect the situation on site.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
