[0027] Please refer to Figures 1-7 The utility model provides a kind of technical scheme: a kind of raw material's pulverizing device for chemical equipment, including pulverizing box 1 and the crushing roller 2 of rotation setting in pulverizing box 1, including,

[0028] The net barrel 301 is slidingly arranged in the crushing box 1, one side of the crushing box 1 is rotationally connected with a driving gear 302, the driving gear 302 is meshingly connected with a connecting rack 303, one end of the connecting rack 303 extends into the crushing box 1 and abuts against one side of the net barrel 301, the other side of the net barrel 301 is connected with a return spring 304, the other side of the return spring 304 is connected to the inner side wall of the crushing box 1, and one side of the crushing box 1 is provided with a servo motor 305 for driving the driving gear 302 to rotate.

[0029] It should be noted that the driving gear 302 is a half gear, that is, the number of its teeth occupies half of its total length.

[0030] In specific implementation, the servo motor 305 drives the driving gear 302 to start rotating.

[0031] In the initial rotating stage of the driving gear 302, since the tooth part of the driving gear 302 is meshed with the connecting rack 303, with the rotation of the driving gear 302, the tooth part pushes the connecting rack 303 to move in the horizontal direction. The connecting rack 303 abuts against the net barrel 301, thereby pushing the net barrel 301 to slide in the crushing box 1 away from the return spring 304, at this time, the return spring 304 is gradually compressed, and its elastic force also continuously increases.

[0032] With the continuous rotation of the driving gear 302, when the tooth part gradually disengages from the meshing with the connecting rack 303, since the connecting rack 303 is no longer pushed by the tooth part at this time, and the return spring 304 stores elastic potential energy in the compressed state, its elastic force starts to play a role, pushing the net barrel 301 to slide back along the original direction, driving the connecting rack 303 to also move reversely, until the next rotation of the driving gear 302, the tooth part again meshes with the connecting rack 303, and the process of pushing the net barrel 301 to slide is repeated, the setting makes the net barrel 301 slide reciprocally, thereby avoiding that the crushed raw materials are blocked in the hole diameter.

[0033] Referring to Figure 5 The top of the net barrel 301 is connected with a guide rod 4, and the guide rod 4 is slidingly connected to the inner top wall of the crushing box 1.

[0034] In specific implementation, the guide rod 4 is arranged to limit and guide the sliding of the net barrel 301, further improving the stability of the net barrel 301 in the sliding process.

[0035] Referring to Figure 5The side of the driving gear 302 is coaxially provided with a connecting disc 501, the connecting disc 501 is rotationally connected with a connecting rod 502, the other end of the connecting rod 502 is rotationally connected with a lifting piece 503, one side of the lifting piece 503 extends into the crushing box 1, the crushing box 1 is slidably connected with a piercing frame 504, and one side of the lifting piece 503 is connected with the bottom of the piercing frame 504.

[0036] In specific implementation, when the driving gear 302 is rotated by the servo motor 305, the connecting disc 501 coaxially arranged with the driving gear 302 is also synchronously rotated, and the rotation of the connecting disc 501 drives the connecting rod 502 to make a circular motion, and since the other end of the connecting rod 502 is rotationally connected with the lifting piece 503, the lifting piece 503 is pushed to make up-down reciprocating motion in the circular motion process of the connecting rod 502, and when the lifting piece 503 moves upward, one side of the lifting piece 503 abuts against the bottom of the piercing frame 504, thereby pushing the piercing frame 504 to slide upward in the crushing box 1, and the upward movement of the piercing frame 504 can pierce or vibrate the mesh barrel 301, which helps to unblock the raw materials blocked in the mesh holes.

[0037] Referring to Figure 7 One side of the crushing box 1 is connected with a mounting plate 7, the mounting plate 7 is connected with a connecting plate 8, one side of the lifting piece 503 is connected with a second limiting plate 9, and the second limiting plate 9 is slidably connected to one side of the connecting plate 8.

[0038] In specific implementation, the second limiting plate 9 can limit and guide the sliding of the lifting piece 503, and further improve the stability of the lifting piece 503 in the sliding process.

[0039] Referring to Figure 6 The top of the piercing frame 504 is integrally formed with a plurality of protrusions, and the top of each protrusion is provided with a rounded corner.

[0040] In specific implementation, the plurality of protrusions on the top of the piercing frame 504 can effectively penetrate the blocked raw materials on the mesh barrel 301 in the up-down movement process, and the rounded corner can avoid the sharp protrusions directly scratching or puncturing the mesh surface of the mesh barrel 301, thereby reducing the risk of damage to the mesh barrel 301.

[0041] Referring to Figure 6 One side of the piercing frame 504 is connected with a first limiting plate 6, and the other side of the first limiting plate 6 is slidably connected to the inner side wall of the crushing box 1.

[0042] In specific implementation, the first limiting plate 6 can limit and guide the sliding of the piercing frame 504, and further improve the stability of the piercing frame 504 in the sliding process.

[0043] Referring to Figure 1 The top of the crushing box 1 is provided with a feeding hopper, and the bottom of the crushing box 1 is provided with a discharging port.

[0044] In particular implementation, the setting facilitates feeding or discharging.

[0046] In particular implementation, the crushing frame 10 is arranged to facilitate crushing of the chemical raw materials in the mesh barrel 301.

[0047] Working principle: the servo motor 305 drives the driving gear 302 to start rotating.

[0048] In the initial rotating stage of the driving gear 302, since the tooth part of the driving gear 302 is engaged with the connecting rack 303, with the rotation of the driving gear 302, the tooth part pushes the connecting rack 303 to move horizontally. One end of the connecting rack 303 abuts against the mesh barrel 301, thereby pushing the mesh barrel 301 to slide in the crushing box 1 away from the reset spring 304, at this time, the reset spring 304 is gradually compressed, and its elastic force also continuously increases.

[0049] With the continuous rotation of the driving gear 302, when the tooth part gradually disengages from the engagement with the connecting rack 303, since the connecting rack 303 is no longer pushed by the tooth part at this time, and the reset spring 304 stores elastic potential energy in the compressed state, its elastic force starts to work, pushing the mesh barrel 301 to slide back along the original direction, and the connecting rack 303 also moves reversely, until the next rotation of the driving gear 302, the tooth part engages with the connecting rack 303 again, and the process of pushing the mesh barrel 301 to slide is repeated, the arrangement makes the mesh barrel 301 slide reciprocally, thereby avoiding the clogging of the crushed raw materials in the aperture;

[0050] When the driving gear 302 is rotated by the servo motor 305, the connecting disc 501 coaxially arranged with the driving gear 302 also rotates synchronously, the rotation of the connecting disc 501 drives the connecting rod 502 to make a circular motion, since the other end of the connecting rod 502 is rotatably connected with the lifting piece 503, in the circular motion process of the connecting rod 502, the lifting piece 503 is pushed to move up and down, when the lifting piece 503 moves upward, one side thereof abuts against the bottom of the puncture frame 504, thereby pushing the puncture frame 504 to slide upward in the crushing box 1, the upward movement of the puncture frame 504 can puncture or vibrate the mesh barrel 301, which is helpful to unblock the raw materials clogged in the mesh hole.
