[0025] 2. Beneficial effects

[0026] Compared with existing technologies, the advantages of this utility model are:

[0027] This invention uses a pair of relatively rotating crushing rollers to pressurize and crush large quartz blocks. The crushed smaller quartz fragments are then further crushed by a second relatively rotating crushing roller to produce smaller quartz particles. This two-step crushing process avoids the problems associated with directly crushing small quartz particles, which would result in high pressure on the quartz, a high probability of it flying out of the environment, and a high pressure load on the crushing equipment.

[0028] Meanwhile, during the crushing and ejection of quartz stone, it is intercepted by the protective box and suction hood. The quartz stone feeding structure has multiple curved guide channels, which guide the quartz stone through its inclined inner wall. The connection with the protective box is also inclined, which avoids the problem of quartz stone flying out of the outside during the crushing process and improves the safety of the quartz stone crushing and processing process.

[0029] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0046] Example 1

[0047] Please see Figures 1-5 As shown, this embodiment is a quartz stone crushing device, including,

[0048] The crushing structure 200 includes a crushing box 201, a motor 206 and a motor 207 symmetrically distributed at the rear end of the crushing box 201, a crushing roller 203 located at the output end of the motor 206 and rotatably installed inside the crushing box 201, a crushing roller 205 located at the output end of the motor 207 and rotatably installed inside the crushing box 201, and a feed inlet 208 located at the upper end of the crushing box 201.

[0049] The protective structure 300 includes a protective box 301 fixed at the upper end of the feed inlet 208 and a guide trough 304 installed through the inside of one end of the protective box 301.

[0050] Inside the crushing box 201, there are guide plates 202 that are relatively distributed above the crushing roller 203 and guide plates 204 that are relatively distributed above the crushing roller 205.

[0051] The protective box 301 has an inspection port 303 at the front end, and an inspection door 302 is rotatably installed at the front end of the inspection port 303. A hydraulic rod 305 is provided on one side of the protective box 301, and a clamping plate 306 is provided at the telescopic end of the hydraulic rod 305.

[0052] The protective structure 300 is used;

[0053] Quartz stone is input through the feed chute 304 and conveyed into the protective box 301. After entering the crushing box 201, the quartz stone blocks are guided by the first guide plate 202. The first motor 206 drives the first crushing roller 203 to rotate relative to each other, crushing the passing quartz stone blocks. The initially crushed quartz stone particles fall downwards and enter the second crushing roller 205 through the second guide plate 204. The second motor 207 drives the second crushing roller 205 to rotate relative to each other, crushing the passing quartz stone particles a second time, reducing the load on the single crushing equipment and improving the crushing effect of the quartz stone in the second crushing.

[0054] During the quartz stone crushing process, the crushed and ejected quartz stone particles are intercepted by the protective box 301 and the suction hood 401, preventing the quartz stone particles from being sprayed into the outside world and causing personnel to be injured or surrounding equipment or objects to be impacted and contracted. It also avoids extra cleaning work and wastes quartz stone, thus improving safety during the quartz stone crushing process.

[0055] Example 2

[0056] Please see Figures 1-5 As shown, this embodiment further includes elements beyond those in embodiment 1;

[0057] as well as;

[0058] The screening structure 500 includes a screen 503 fixed below the crushing box 201;

[0059] The dust removal structure 400 includes a collection box 406 fixed to one side of the crushing box 201, a suction hood 401 fixed above the protective box 301, a fan 403 located inside one end of the collection box 406, and a suction pipe 402 communicating with the suction hood 401 and the collection box 406.

[0060] The outer wall of the crushing box 201 is fitted with a mounting frame 100, and a conveyor 505 located below the screen 503 is provided at the upper end of the mounting frame 100.

[0061] Baffles 501 are provided on both the front and rear sides of the upper end of the sieve 503;

[0062] The lower end of the crushing box 201 is provided with a guide groove 502 located below the crushing roller 205. The lower end opening of the guide groove 502 is located on the side above the screen 503. The material box 504 is provided on the side below the screen 503.

[0063] Inside the collection box 406, there is a filter cover 404 located outside the suction end of the fan 403. The inner wall of the collection box 406 is provided with an inclined plate 405 located on one side below the filter cover 404. The lower end of the collection box 406 is provided with a discharge pipe 407 that is controlled to open and close by a valve.

[0064] The dust removal structure 400 is used;

[0065] During the quartz stone crushing and processing, the crushed quartz stone particles enter the screen 503 through the guide channel 502 and are screened by the screen 503. Quartz stone particles with a size larger than the gap of the screen 503 are intercepted by the screen 503 and flow into the material box 504 through the inclined surface of the screen 503. Non-compliant quartz stone particles are collected, and qualified quartz stone particles are transported by the conveyor 505 after passing through the screen 503.

[0066] Furthermore, dust is generated when crushing quartz particles. The fan 403 operates to generate suction force, which is transmitted through the suction pipe 402 and guided into the protective box 301 through the suction hood 401. This suction force removes the generated dust, reduces dust pollution, improves the quality of the working environment, and protects workers from inhaling too much dust, thus preventing damage to their respiratory system.
