[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0028] like Figure 1-4 As shown, an embodiment of the utility model provides a stone crusher, which comprises:

[0029] A feed hopper 1, a crushing body 2 and a pushing assembly 3, wherein the feed hopper 1 is tilted and a lower end thereof is docked with the crushing body 2, the crushing body 2 comprises a box 21 and a crushing assembly 22, the box 21 is docked with the feed hopper 1, the crushing assembly 22 is arranged in the box 21 for crushing the stones entering the box 21, and the pushing assembly 3 has a plurality of telescopic ends extending into the box 21, and the plurality of telescopic ends are staggered and telescopic to push the stones in the box 21 to move.

[0030] The stone crusher proposed in the utility model is provided with a pushing assembly 3 in the crushing body. The pushing assembly 3 has a plurality of telescopic ends extending into the box body 21. The plurality of telescopic ends are staggered and telescopic to push the stone in the box body 21 to move, so as to move the material at the feed port and avoid blockage of the feed port.

[0031] Specifically, guardrails are extended on both sides of the feeding hopper 1 to prevent stones from overflowing when being introduced.

[0032] Furthermore, it also includes a material shaking component 4, which is connected to the feed hopper 1 and is used to drive the feed hopper 1 to reciprocate, so that the material is shaken in the feed hopper 1 and falls into the crushing body 2.

[0033] Furthermore, the shaking assembly 4 includes a rotating motor 41, an eccentric wheel 42 and an elastic member 43. The output end of the rotating motor 41 is connected to the eccentric wheel 42 shaft, the eccentric wheel 42 is in contact with the bottom of the feed hopper 1, the lower end of the feed hopper 1 is hinged to the crushing body 2, and the two ends of the elastic member 43 are respectively connected to the wall and the feed hopper 1. When working, the rotating motor 41 drives the eccentric wheel 42 to rotate, and the eccentric wheel 42 further drives the feed hopper 1 to rotate up and down, so that the material in the feed hopper 1 shakes up and down to prevent the stone from being squeezed and stuck in the feed hopper 1 layer by layer.

[0034] Furthermore, the elastic member 43 is a spring, and both ends of the spring are respectively connected to the wall and the hopper 1. The spring is used to limit the maximum distance between the hopper 1 and the wall, and can apply a pulling force to the hopper 1 to quickly reset it.

[0035] Specifically, the crushing assembly 22 includes a pair of crushing rollers 221 and a driving mechanism. The crushing rollers 221 are rotatably fixed in the box body 21. The driving mechanism is connected to the shafts of the crushing rollers 221 to drive the pair of crushing rollers 221 to rotate relative to each other.

[0036] Furthermore, a pair of crushing rollers 221 are arranged parallel to each other, wherein the diameter of one crushing roller 221 gradually decreases along the first direction, and the diameter of the other crushing roller 221 gradually increases along the first direction. It can be seen that the interval between the crushing rollers 221 is arranged obliquely, which can provide an oblique force when squeezing stones to prevent the stones from being stuck between the crushing rollers 221.

[0037] Furthermore, the crushing roller 221 is provided with a plurality of protrusions protruding relative to the crushing roller 221. The protrusions can enhance the crushing effect on the stone.

[0038] Furthermore, the pushing assembly 3 includes a plurality of pushing pieces 31, which are fixed in the box body 21. The pushing pieces 31 have telescopic ends that can be telescoped relative to the inner wall of the box body 21. The telescopic ends of the pushing pieces 31 are staggered and telescoped to push the stone to move.

[0039] Furthermore, the pushing assembly 3 further includes a flexible member 32, which is fixed in the box 21 and covers the telescopic end of the pushing member 31. The telescopic ends of the pushing members 31 are staggered and telescopic, so that the flexible member 32 pushes the stone to move. The purpose of sleeve-mounting the flexible member 32 on the pushing member 31 is to prevent the stone from getting stuck between the pushing members 31 and affecting the telescopic movement of the pushing members 31.

[0040] Furthermore, the flexible member 32 is a sheet material made of polypropylene material, which has strong tear resistance, can prevent stones from getting stuck between the pusher members 31, and can resist sharp cuts from stones, thus having a long service life.

[0041] When the utility model is in use, first, the stone to be processed is poured into the feed hopper 1, and the rotating motor 41 drives the eccentric wheel 42 to rotate, and the eccentric wheel 42 further pushes the feed hopper 1 to rotate up and down, so that the material in the feed hopper 1 shakes up and down to avoid the stone being squeezed and stuck layer by layer in the feed hopper 1, and the material slides along the feed hopper 1 toward the box body 21, and the stone is broken into small pieces and discharged under the action of the crushing roller 221. When there are many stones, stacking may occur on the crushing roller 221, and the telescopic ends of the pusher 31 are staggered and telescopic, so that the flexible member 32 pushes the stone to move, so that the stone located above the crushing roller 221 moves to avoid stacking and jamming, and the intervals between the crushing rollers 221 are arranged obliquely, which can provide an oblique force when squeezing the stone to avoid the stone being stuck between the crushing rollers 221.

[0042] The beneficial effects of the utility model are:

[0043] The stone crusher proposed by the utility model is provided with a pushing assembly in the crushing body. The pushing assembly has a plurality of telescopic ends extending into the box body. The plurality of telescopic ends are staggered and telescopic to push the stone in the box body to move, so as to move the material at the feed port and avoid blockage of the feed port.

[0044] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
