[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1-4 As shown in the figure, this embodiment proposes a chemical raw material crushing device, including a box body 1, a support plate 21 fixedly connected inside the box body 1, the support plate 21 is arranged in a horizontal direction, and a crushing frame 11 located above the support plate 21 is fixedly connected to the box body 1. The crushing frame 11 has a hollow structure and both the upper and lower ends of the crushing frame 11 are open, so as to facilitate feeding and discharging.

[0029] The support plate 21 is slidably connected to a crushing plate 14 for receiving materials. The crushing plate 14 is located between the support plate 21 and the crushing frame 11, forming a crushing space for accommodating materials. The support plate 21 has a discharge port 18 located directly below the crushing frame 11. One end of the crushing plate 14 is also fixedly connected to a screen 16 that can slide into the discharge port 18. The gap between the crushing frame 11 and the support plate 21 is sufficiently suitable to facilitate the sliding of the crushing plate 14 within the gap.

[0030] The lower end of the crushing plate 14 is slidably connected to the support plate 21, and the upper end of the crushing plate 14 is slidably connected to the crushing frame 11. When the crushing plate 14 slides to the right out of the crushing frame 11, the material above the crushing plate 14 is intercepted by the crushing frame 11 and remains inside the crushing frame 11, allowing the material to slide onto the screen 16, thus facilitating the screening of the material. At the same time, the screen 16 is connected to a vibrator 17, which also facilitates the screening of the material.

[0031] The box body 1 is fixedly connected to the storage box 2, and the box body 1 is fixedly connected to the feed pipe 5. One end of the feed pipe 5 is connected to the storage box 2, and the other end of the feed pipe 5 is located above the crushing frame 11. The material in the storage box 2 can fall into the crushing frame 11 through the feed pipe 5, thereby realizing feeding. The box body 1 is connected to the discharge pipe 4, which is located below the support plate 21.

[0032] The housing 1 is fixedly connected to an electric push rod 19, which is connected to a baffle 20. The baffle 20 is slidably connected to the feed pipe 5 and the housing 1. The lower end of the baffle 20 can slide into the feed pipe 5 to block the feed pipe 5. When the electric push rod 19 drives the baffle 20 to rise, the feed pipe 5 opens, and the material in the feed pipe 5 can fall into the crushing frame 11.

[0033] When the crushing plate 14 slides into the crushing frame 11, the raw material can be crushed. When the crushing plate 14 slides out of the crushing frame 11, the crushing plate 14 drives the screen 16 to slide into the crushing frame 11, which can screen the material in the crushing frame 11 and feed the raw material at the same time. The raw material that meets the requirements can be screened first. The operation is convenient and can realize the intermittent crushing and screening of chemical raw materials. During the crushing interval, the raw material is screened, which can effectively improve the efficiency of chemical raw material crushing.

[0034] The support plate 21 is connected to a switch 15 that controls the operation of the electric push rod 19. The switch 15 is located on one side of the crushing plate 14. When the screen 16 slides into the crushing frame 11, the switch 15 and the electric push rod 19 are connected to a controller. The crushing plate 14 cooperates with the switch 15 to make the electric push rod 19 work.

[0035] Switch 15 can be a proximity switch. The end of the crushing plate 14 near switch 15 is connected to a sensing plate that cooperates with switch 15. A proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When the sensing plate approaches the sensing surface of the proximity switch to the operating distance, the switch can be activated without mechanical contact or applying any pressure, thereby providing control commands to the controller. The controller controls the electric push rod 19 to work, so that the feed pipe 5 is opened.

[0036] The housing 1 is slidably connected to a vertically moving hammer handle 6. The hammer handle 6 is detachably connected to a breaker hammer 7. The breaker hammer 7 is located above the crushing frame 11, and the material discharge port 18 is located directly below the breaker hammer 7. When the crushing plate 14 slides into the material discharge port 18, the crushing plate 14 is a solid plate. At this time, the breaker hammer 7 falls to the crushing plate 14 and rises, which can realize the crushing work of the material on the crushing plate 14.

[0037] The housing 1 is rotatably connected to the first gear 8, the first gear 8 is connected to the motor, the motor and the housing 1 are fixedly connected, the motor includes an output shaft, the first gear 8 is fixedly sleeved on the output shaft, a rack is fixedly connected to one side of the hammer handle 6, the first gear 8 and the rack mesh, the motor can drive the first gear 8 to rotate, and the first gear 8 can drive the breaker hammer 7 to rise.

[0038] The housing 1 is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to a telescopic rod 12. The other end of the telescopic rod 12 is hinged to the crushing plate 14. When the rotating shaft rotates, it can drive the telescopic rod 12 to rotate, and the telescopic rod 12 can drive the crushing plate 14 to move horizontally.

[0039] The telescopic rod 12 is connected to the housing 1 via the spring 13. The left end of the spring 13 is connected to the housing 1, and the right end of the spring 13 is connected to the telescopic rod 12. The elastic force of the spring 13 allows the crushing plate 14 to slide into the crushing frame 11. When the telescopic rod 12 drives the crushing plate 14 to move to the right, the spring 13 is stretched.

[0040] The housing 1 is rotatably connected to the second gear 9, and the third gear 10 is rotatably fixedly sleeved. The third gear 10 meshes with the second gear 9. The first gear 8 can drive the second gear 9 to rotate through the synchronous belt. The second gear 9 can drive the third gear 10 to rotate. The third gear 10 drives the telescopic rod 12 to rotate through the rotating shaft, thereby realizing the horizontal movement of the crushing plate 14.

[0041] The first gear 8 is coaxially and fixedly connected to the first pulley, and the second gear 9 is coaxially and fixedly connected to the second pulley. The synchronous belt is sleeved on the first pulley and the second pulley. Therefore, when the motor drives the first gear 8 to rotate, it can drive the second gear 9 to rotate synchronously through the synchronous belt.

[0042] Both the first gear 8 and the second gear 9 are toothless gears. Therefore, when the first gear 8 and the rack disengage, the breaker 7 descends under the action of gravity to achieve crushing. When the second gear 9 and the third gear 10 disengage, the spring 13 drives the crushing plate 14 to reset, which enables the crushing plate 14 to move into the crushing frame 11.

[0043] When the first gear 8 drives the breaker hammer 7 to rise, the second gear 9 drives the crushing plate 14 to move, allowing the screen 16 to slide into the crushing frame 11. When the second gear 9 and the third gear 10 disengage, and the spring 13 drives the crushing plate 14 to reset, the first gear 8 is still engaged with the rack and will continue to drive the breaker hammer 7 to rise. After moving for a period of time, the first gear 8 will disengage from the rack and the breaker hammer 7 will then descend, thus crushing the material.

[0044] When the first gear 8 drives the breaker hammer 7 to rise, the second gear 9 drives the telescopic rod 12 to rotate. The telescopic rod 12 drives the crushing plate 14 to move, so that the raw material can be screened when the breaker hammer 7 rises. At the same time, when the crushing plate 14 moves to the end, the crushing plate 14 and the switch 15 cooperate, and the electric push rod 19 drives the baffle 20 to rise, so as to realize the feeding of raw materials. This achieves both initial screening of raw materials and feeding of raw materials, thereby effectively simplifying the crushing process and improving the crushing efficiency.

[0045] The specific working process is as follows: The motor drives the first gear 8 to rotate, the first gear 8 drives the breaker hammer 7 to rise, and at the same time the first gear 8 drives the second gear 9 to rotate. The second gear 9 drives the telescopic rod 12 to rotate through the third gear 10. The telescopic rod 12 drives the crushing plate 14 to move to the right, so that the screen 16 slides into the crushing frame 11.

[0046] When the crushing plate 14 and the switch 15 are in sync, the switch 15 controls the electric push rod 19 to work. The electric push rod 19 drives the baffle 20 to rise, and the material in the storage box 2 falls into the crushing frame 11 through the feed pipe 5, and then falls onto the screen 16. At this time, the material is initially screened, and the material that meets the requirements falls into the discharge pipe 4 through the screen 16.

[0047] As the first gear 8 continues to rotate, when the second gear 9 and the third gear 10 disengage, the spring 13 drives the crushing plate 14 to reset. At this time, the first gear 8 is still engaged with the rack and will continue to drive the crusher 7 to rise. After moving for a period of time, the first gear 8 will disengage from the rack and the crusher 7 will descend, thus crushing the material.

[0048] Afterwards, the first gear 8 meshes with the rack, driving the breaker 7 to rise. At the same time, the second gear 9 drives the screen 16 to slide into the crushing frame 11 to screen the crushed material. The above process is repeated to achieve the crushing of chemical raw materials.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
