The connecting mechanism 4 improves the protection performance and safety of the crusher in crushing stones. A dust removal mechanism 5 is provided on the right side of the connecting mechanism 4, and the dust removal mechanism 5 can improve the environmental protection performance.

[0023] See also Figure 2 In order to improve the protection performance and safety of the crusher in crushing stones, in this embodiment, the connecting mechanism 4 includes a support frame 401 fixed to the left and right sides of the crusher body 1 by bolts, and an electric push rod 402 is fixed to the upper surface of the support frame 401. Limit rods 403 are fixed on the left and right sides of the bottom wall of the inner cavity of the support frame 401. The outer side of the limit rod 403 is slidably connected to the limit slide 404, and a protective frame 405 is fixed on the opposite side of the left and right limit slides 404. The outer side of the output shaft of the electric push rod 402 passes through the support frame 401 and is fixedly connected to the top of the protective frame 405.

[0024] In this embodiment, the outer side of the output shaft of the electric push rod 402 is slidably connected to the inside of the support frame 401, and the stones can be poured into the inside of the crusher body 1 through the protective feed hopper 3. The crusher body 1 can be opened to crush the stones inside the crusher body 1, and the crushed stones are discharged through the discharge port 2. When the crusher body 1 is crushing the stones, the electric push rod 402 can be started, and the output shaft of the electric push rod 402 drives the protective frame 405 to move downward.

[0025] In this embodiment, the connecting mechanism 4 also includes a sealing rubber layer 406 fixed on the top wall of the inner cavity of the protective frame 405, and support rods 407 are fixed on the left and right side walls of the inner cavity of the support frame 401. The opposite sides of the left and right support rods 407 are fixedly connected to the opposite sides of the left and right limit rods 403, and the limit slide 404 moves linearly up and down on the outside of the limit rod 403.

[0026] It should be noted that the left and right limit slides 404 slide downward synchronously on the outside of the left and right limit rods 403. The left and right limit slides 404 cooperate with the left and right limit rods 403 to improve the stability of the downward movement of the protective frame 405. The protective frame 405 moves downward until it covers the top of the protective feed hopper 3, and the lower surface of the sealing rubber layer 406 contacts the upper surface of the protective feed hopper 3. At this time, the electric push rod 402 is closed, thereby improving the protection performance and safety of the crusher in crushing stones.

[0027] See also Figure 3-4In order to improve the environmental protection performance, in this embodiment, the dust removal mechanism 5 includes a collecting box 501 fixed to the right side of the supporting frame 401, and two exhaust fans 502 are fixed on the upper surface of the collecting box 501. The input end of the exhaust fan 502 is connected to the upper surface of the collecting box 501 through a pipeline, and a filter screen 503 is fixed on the upper side of the inside of the collecting box 501, and a connecting component is provided on the front of the collecting box 501.

[0028] In this embodiment, the connecting assembly includes a sealing door 504 which is rotatably connected to the front of the collecting box 501 through a hinge, and a dust extraction cylinder 505 is fixed by bolts on the lower surface of the crusher body 1 and located on the right side of the discharge port 2. A connecting pipe 506 is connected to the right side of the dust extraction cylinder 505, and the end of the connecting pipe 506 away from the dust extraction cylinder 505 is connected to the back of the collecting box 501. When the discharge port 2 is unloading, the two exhaust fans 502 can be started at the same time. The dust generated when the crushed stones are unloaded flows into the interior of the collecting box 501 through the dust extraction cylinder 505 and the connecting pipe 506. A handle is fixed on the front of the sealing door 504, and a non-slip rubber sleeve is fixed on the outside of the handle. The sealing door 504 is fixed to the front of the collecting box 501 by a snap lock.

[0029] It should be noted that the air inside the collection box 501 is discharged through the filter 503 and two exhaust fans 502, and then the collected dust stays inside the collection box 501. By opening the sealed door 504 on the front of the collection box 501, the collected dust can be taken out, thereby improving the environmental protection performance.

[0030] The working principle of the above embodiment is:

[0031] (1) Stones can be poured into the crusher body 1 through the protective feed hopper 3. The crusher body 1 can be opened to crush the stones inside the crusher body 1. The crushed stones are discharged through the discharge port 2. When the crusher body 1 is crushing stones, the electric push rod 402 can be started. The output shaft of the electric push rod 402 drives the protective frame 405 to move downward. The left and right limit slides 404 slide downward synchronously on the outside of the left and right limit rods 403. The left and right limit slides 404 and the left and right limit rods 403 cooperate with each other to improve the stability of the protective frame 405 moving downward. The protective frame 405 moves downward until it covers the top of the protective feed hopper 3. The lower surface of the sealing rubber layer 406 contacts the upper surface of the protective feed hopper 3. At this time, the electric push rod 402 is closed, thereby improving the protective performance and safety of the crusher in crushing stones.

[0032] (2) When the material is discharged from the discharge port 2, the two exhaust fans 502 can be started at the same time. The dust generated when the gravel is discharged flows into the interior of the collection box 501 through the dust extraction cylinder 505 and the connecting pipe 506. The air inside the collection box 501 is discharged through the filter 503 and the two exhaust fans 502. Then the collected dust stays in the interior of the collection box 501. By opening the sealing door 504 on the front of the collection box 501, the collected dust can be taken out, thereby improving the environmental protection performance.
