It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a mineral material crushing and cleaning device, including a crushing box 1 and a cleaning box 2, the cleaning box 2 is located at the bottom of the crushing box 1, a feeding hopper 3 is fixedly connected to the top of the crushing box 1, crushing rollers 5 are symmetrically arranged on the inner surface of the crushing box 1, a motor 4 is fixedly connected to the outer surface of the crushing box 1, the motor 4 slides through the crushing box 1 and extends to the inner side, a rotating shaft 6 is fixedly connected to the output end of the motor 4, an eccentric wheel 7 is symmetrically fixedly connected to the outer surface of the rotating shaft 6, a plurality of springs 8 are fixedly connected to the inner surfaces of both sides of the crushing box 1 at equal distances, a guide plate 9 is fixedly connected between the end surfaces of two groups of springs 8, the guide plate 9 is located at the lower side of the crushing roller 5, the bottom of the guide plate 9 is in an open state, a mesh plate 10 is fixedly connected to the bottom of the guide plate 9, and the bottom of the guide plate 9 is fixedly connected to the mesh plate 10. A first air suction hood 11 is fixedly connected, a hose 12 is fixedly connected to the bottom of the first air suction hood 11, a first dust suction device 13 is fixedly connected to the outer surface of the crushing box 1, an output end of the first dust suction device 13 passes through the crushing box 1 and is fixedly connected to the hose 12, a notch is provided on the outer surface of the crushing box 1, a second air suction hood 14 is fixedly connected to the outer surface of the crushing box 1 near the notch, a connecting pipe 15 is fixedly connected to the outer surface of the second air suction hood 14, a protective cover 19 is fixedly connected to the inner surface of the crushing box 1 near the notch, a second dust suction device 16 is fixedly connected to the outer surface of the crushing box 1, the connecting pipe 15 is fixedly connected to the output end of the second dust suction device 16, a blanking plate 18 is fixedly connected to the inner surface of the crushing box 1, and the blanking plate 18 is located at the lower side of the guide plate 9.

[0023] The effect achieved by the entire embodiment 1 is that when the mineral raw materials are crushed and cleaned, the mineral raw materials are put into the crushing box 1 from the feeding hopper 3, and the crushing roller 5 rotates to crush the mineral raw materials. The mineral raw materials that have completed the crushing process will fall onto the surface of the guide plate 9. The motor 4 is started to drive the eccentric wheel 7 to rotate. The rotation of the eccentric wheel 7 will repeatedly knock on the side of the guide plate 9, so that the guide plate 9 generates high-frequency vibration. Under the high-frequency vibration of the guide plate 9, the mineral raw materials will slowly slide down along the inclined surface of the guide plate 9 for unloading. When the guide plate 9 vibrates, the vibration will be transmitted to the mineral raw materials. When the crushed mineral raw materials experience high-frequency vibration, the dust mixed in the mineral raw materials It will be lifted up by the airflow generated by the vibration, forming a visible dust raising phenomenon. After the dust is raised, the second dust suction device 16 can be started to absorb the dust generated in the crushing box 1 from the second air suction hood 14 through the connection of the connecting pipe 15. The second air suction hood 14 is protected by the setting of the protective cover 19. At the same time, the first dust suction device 13 is started. The first dust suction device 13 can absorb the dust sieved out from the mesh plate 10 from the first air suction hood 11 through the connection of the hose 12. The dust cleaning in the mineral raw materials is more thorough. After the mineral raw materials are crushed and dust cleaned, the mineral raw materials slide along the unloading plate 18 with a larger inclination angle into the cleaning box 2 for cleaning.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, an anti-collision plate 17 is fixedly connected to the inner surface of the crushing box 1 , and the anti-collision plate 17 is located at the lower side of the hose 12 .

[0025] The effect achieved by the entire embodiment 2 is that the anti-collision plate 17 can protect the hose 12, preventing the mineral raw materials from falling to the discharge plate 18 and bouncing up to damage the hose 12 during discharge, thereby improving the service life of the device.

[0026] Working principle: When the mineral raw materials are crushed and cleaned, the mineral raw materials are put into the crushing box 1 from the feeding hopper 3, and the crushing roller 5 is driven by the driving device. The crushing roller 5 rotates to crush the mineral raw materials. The mineral raw materials that have been crushed will fall onto the surface of the guide plate 9. The inclination angle of the guide plate 9 is small, and the mineral raw materials will not slip on the surface of the guide plate 9. When the motor 4 is started, it can drive the eccentric wheel 7 to rotate through the connection of the rotating shaft 6. Since the guide plate 9 is supported by multiple springs 8 on both sides, the eccentric The rotation of the wheel 7 will repeatedly knock the side of the guide plate 9, causing the guide plate 9 to generate high-frequency vibration. Under the high-frequency vibration of the guide plate 9, the mineral raw materials will slowly slide down along the inclined surface of the guide plate 9 for unloading. While the guide plate 9 vibrates, the vibration will be transmitted to the mineral raw materials. When the crushed mineral raw materials experience high-frequency vibration, due to gravity, the heavier granular mineral raw materials will fall quickly, and the dust mixed in the mineral raw materials will be carried up by the airflow generated by the vibration and suspended in the air, forming a visible dust raising phenomenon. After the dust is raised, the second dust suction device 16 is started to absorb the dust generated in the crushing box 1 from the second air suction hood 14 through the connection of the connecting pipe 15. The second air suction hood 14 is protected by the setting of the protective cover 19. At the same time, the first dust suction device 13 is started. The first dust suction device 13 can absorb the dust sieved out from the mesh plate 10 position from the first air suction hood 11 position through the connection of the hose 12, which is more thorough for cleaning the dust in the mineral raw materials. After the mineral raw materials are crushed and dust cleaned, the mineral raw materials slide along the unloading plate 18 with a larger inclination angle to the cleaning box 2 for cleaning. By setting up vibration dust cleaning after the mineral raw materials are crushed, the mineral raw materials can be kept in a relatively uniform granular state and enter the cleaning box 2 for cleaning, which solves the problem that the mineral raw materials with more dust attached enter the cleaning box 2 and are not thoroughly cleaned. The anti-collision plate 17 can protect the hose 12 to prevent the mineral raw materials from falling to the unloading plate 18 and bouncing up to damage the hose 12 when discharging, thereby improving the service life of the device.

[0027] The wiring diagram of the cleaning box 2, the motor 4, the first dust suction device 13 and the second dust suction device 16 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the cleaning box 2, the motor 4, the first dust suction device 13 and the second dust suction device 16 are not explained in detail.
