Cold bin discharge device with anti-splashing function

Abstract

This utility model relates to the technical field of cold material silo discharge equipment, specifically a cold material silo discharge device with anti-splash function. It includes a protective component, the inner wall of which is slidably connected to the outer wall of the screening component. A motor drives an eccentric wheel to rotate via a rotating shaft. When the eccentric wheel contacts and pushes the roller, the roller drives the mounting frame and screen to vibrate up and down via a support block and support shaft. Vibration promotes material screening on the screen, improving screening efficiency. A spring acts as a buffer and reset mechanism, ensuring the mounting frame returns to its initial position after vibration. A protective side plate prevents material from splashing and injuring workers during vibration on the screen. A first and second buffer block reduce the discharge speed of the screened material, helping it flow out more smoothly and avoiding splashing due to excessive material speed. A push plate 504 moves to evenly distribute the material on the screen 202, preventing uneven screening and efficiency reduction caused by material accumulation.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a cold material bin discharge device with anti-splash function, including a protective component 1, the inner wall of the protective component 1 is slidably connected to the outer wall of the screening component 2, and the inner wall of the protective component 1 is rotatably connected to the outer wall of the driving component 3 near the center. The protective component 1 is composed of a protective side plate 101, a sliding groove 102, a first rotating hole 103, a second rotating hole 104, a connecting block 105, a first buffer block 106, a rotating groove 107, a second buffer block 108, and a baffle plate 109.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the transmission component 4 includes a support block 401, a support shaft 402, and rollers 403. The inner wall of the support block 401 is fixedly connected to the outer walls at both ends of the support shaft 402, and the outer wall at the center of the support shaft 402 is rotatably connected to the inner wall of the rollers 403.

The outer walls of the two sets of rollers 403 are movably abutting against the outer walls of the two eccentric wheels 304. When the eccentric wheels 304 contact the rollers 403 and push the rollers 403, the rollers 403 drive the mounting frame 201 and the screen 202 to vibrate up and down through the support block 401 and support shaft 402. The vibration promotes the screening of materials on the screen 202, improving the screening efficiency. The spring 204 plays a buffering and resetting role, ensuring that the mounting frame 201 can return to its initial position after vibration.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the dispersing component 5 consists of a transmission plate 501, a screw 502, a guide rod 503, and a push plate 504. The inner wall of the transmission plate 501 near the bottom is threadedly connected to the outer wall of the screw 502, and the inner wall of the transmission plate 501 near the top is slidably connected to the outer wall of the guide rod 503. The bottom of the transmission plate 501 is fixedly connected to the top of the push plate 504, and the outer walls of the screw 502 near both ends are rotatably connected to the inner wall of the first rotating hole 103.

Both ends of the guide rod 503 are fixedly connected to the inner wall of the protective side plate 101. The transmission plate 501, screw 502 and guide rod 503 are all set inside the baffle plate 109. When the rotating shaft 303 rotates, it drives the screw 502 to rotate through the transmission belt 305. The screw 502 drives the transmission plate 501 to move along the direction of the guide rod 503 through the thread, so that the push plate 504 moves on the screen 202. After moving from the back of the screen 202 to the front, the motor 302 rotates in the opposite direction to make the push plate 504 move in the opposite direction.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, bearings are provided at the connection points between the rotating shaft 303 and the second rotating hole 104 and between the screw 502 and the first rotating hole 103, and the cross sections of the first buffer block 106 and the second buffer block 108 are both set as triangles.

[0028] The usage and advantages of this utility model: The working process of this cold material bin discharge device with anti-splash function is as follows:

[0029] like Figure 1 , Figure 2 and Figure 3As shown, motor 302 drives eccentric wheel 304 to rotate via shaft 303. When eccentric wheel 304 contacts roller 403 and pushes roller 403, roller 403 drives mounting frame 201 and screen 202 to vibrate up and down via support block 401 and support shaft 402. Vibration promotes material screening on screen 202, improving screening efficiency. Spring 204 acts as a buffer and reset mechanism, ensuring that mounting frame 201 can return to its initial position after vibration. Protective side plate 101 prevents material from splashing and injuring workers when vibrating on screen 202. First buffer block 106 and second buffer block 10 8. Reducing the discharge speed of the screened material helps the material flow out more smoothly and avoids splashing caused by excessive material speed. While the rotating shaft 303 rotates, it drives the screw 502 to rotate through the transmission belt 305. The screw 502 drives the transmission plate 501 to move along the direction of the guide rod 503 through the thread, so that the push plate 504 moves on the screen 202. After moving from the back to the front of the screen 202, the motor 302 rotates in the opposite direction to make the push plate 504 move in the opposite direction. The movement of the push plate 504 makes the material evenly distributed on the screen 202, avoiding the problem of uneven screening and reduced efficiency caused by material accumulation.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
