In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the embodiments of the present application can refer to the same reference numerals and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, which does not indicate the relationship between the various embodiments and / or settings discussed.

[0029] In order to better understand the purpose, structure and function of the present application, the present application will be further described in detail below in combination with the drawings.

[0030] As shown in Figures 1-6 The embodiments of the present application provide a stone crushing device for mine machinery, which comprises a crushing box 100 for crushing mine stones, and a crushing unit 200 arranged inside the crushing box 100 for crushing and processing the stones. The upper end of the crushing box 100 is provided with a suction unit 300 for sucking dust inside the crushing box 100.

[0031] The lower end of the crushing box 100 is provided with a discharge port 120 for discharging the crushed stones. The inside of the discharge port 120 is provided with a filter plate 130 for filtering the crushed stones and dust. One side of the filter plate 130 is inclinedly mounted inside the discharge port 120, and the two sides are movably mounted inside the box body of the crushing box 100.

[0032] The crushing unit 200 comprises two groups of stone crushing teeth 210 for engaging and crushing the stones. The two groups of stone crushing teeth 210 are staggeredly mounted, and the tooth plates of the two groups of stone crushing teeth 210 are symmetrically mounted. The stone crushing teeth 210 are supported and fixed by a support shaft 220 penetratingly mounted in the middle. The support shaft 220 is mounted in the inside of the crushing box 100 through a bearing, and one end is provided with a driving device 110 outside the crushing box 100.

[0033] When crushing gravel, the stone is fed into the crushing box 100 through the feeding device. The crushing teeth 210 at the lower end mesh with the crushed stone and falls from the middle of the crushing teeth 210 to the upper end of the inclined filter plate 130 at the lower end. The filter plate 130 filters the crushed stone, separating the stone powder from the small stones. The stones can be discharged to one side through the filter plate 130 and guided by the conveyor belt for discharge. This separates the ash and stones, making it easier to utilize the stones and ensuring the consistency and stability of product quality.

[0034] The outer side of the stone crushing tooth 210 is provided with a baffle 230 for blocking the crushed stone. The baffle 230 is installed one-to-one with the tooth plate of the stone crushing tooth 210. The baffle 230 is fixedly installed on the outside of the baffle 230 for fixing the baffle 230. The stone crushing tooth 210 in the middle can be blocked by the baffles 230 on both sides to prevent stones from falling from both sides.

[0035] One end of the filter plate 130 is hinged and installed on one side of the crushing box 100. The other end of the filter plate 130 can be fixed by bolts through the crushing box 100. The filter plate 130 can be rotated to adjust the installation angle, thereby facilitating the adjustment of the discharge method.

[0036] The suction unit 300 includes a movable box 310 for support and installation, and a protective component 320 disposed outside the movable box 310 for protecting the movable box 310. The upper end of the protective component 320 is provided with a plurality of exhaust holes 321 for exhausting and dust removal. An exhaust section 400 for exhausting is installed on the other side of the movable box 310. The exhaust section 400 includes a positioning frame 410 for installation and a protective net 420 disposed inside the positioning frame 410 for protection. An exhaust fan 430 for exhausting and dust removal is fixedly installed on the upper end of the protective net 420.

[0037] During the crushing process, ventilation can be achieved through exhaust fan 430 and exhaust port 321 at the top of protective component 320. Protective component 320 can also protect the equipment on the other side, and remove dust from the crushed stone inside crushing box 100 and the dust raised during the feeding process. The dust is then centrally treated to ensure the processing environment during the crushing process.

[0038] The inside of the moving box 310 is provided with a dust storage cavity 311 for storing dust and a ventilation net 312 arranged on one side of the dust storage cavity 311 for blocking the dust, the ventilation net 312 is fixedly installed on the other side of the dust storage cavity 311, and the lower end of the dust storage cavity 311 is provided with a discharge port 313 for discharging dust and small stones, the lower end of the discharge port 313 is arranged at the upper end of the stone crushing tooth 210, during the dust extraction process, the dust is blocked by the ventilation net 312 and discharged downward along the discharge port 313 when accumulated to a certain degree, since the rotating speed of the stone crushing tooth 210 at the lower end is relatively low, the dust cannot be lifted in a large area, and the dust can be conveniently discharged and treated.

[0039] The other side of the moving box 310 is provided with a positioning screw 330 for mounting and fixing the moving box 310, the positioning screw 330 penetrates the fixing piece 140 mounted on the top of the crushing box 100 and is positioned and mounted, the positioning screw 330 is fixed by a rotating nut 350 mounted at the upper end, and the fixing piece 140 and the upper end of the moving box 310 are surrounded by a spring 340 for buffering and positioning, the position of the positioning screw 330 can be adjusted by tightening the rotating nut 350, the relative distance between the lower end of the protective piece 320 and the crushing unit 200 can be adjusted, and the processing is facilitated.

[0040] The working principle of the stone crushing device of the mine machinery is as follows: when the stones are crushed, the stones are put into the inside of the crushing box 100 through the feeding device, the stone crushing tooth 210 arranged at the lower end engages the crushed stones, the crushed stones fall from the middle of the stone crushing tooth 210 and drop onto the upper end of the filter plate 130 arranged at the lower end in a slope, the filter plate 130 filters the crushed stones, the stone powder and small stones are separated, the stones can be guided to one side through the filter plate 130, the material is guided and discharged through the conveying belt, and then the separated dust and stones can be separated, the stones are conveniently utilized, and the consistency and stability of the product quality are ensured.

[0041] It can be understood that the utility model is described through some embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to the features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, the features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the application belong to the scope protected by the utility model.
