[0002] The raw material mixing device for concrete slab production is designed to uniformly mix cement, sand, water, and possible additives in a certain proportion. It plays a crucial role in the concrete slab manufacturing process, ensuring the quality stability and performance consistency of the final product.

[0003] Chinese Patent Publication No. CN219686108U, published on September 15, 2023, discloses a raw material mixing device for the production of aerated concrete panels. The device includes a processing chamber with a feed inlet connected to its top. A dust collection component is installed on the outside of the feed inlet. A crushing roller is installed above the interior of the processing chamber, and a screen is installed below the crushing roller. A vibration component is installed below the screen, and a mixing component is installed below the processing chamber. The dust collection component includes a first dust collection hood, with a first dust collection head inside the hood, and a first dust collection pipe connected to the outside of the first dust collection head.

[0004] Existing raw material mixing devices for concrete slab production, such as those described above, use screens and vibration components to achieve horizontal screen placement. The vibration components vibrate the horizontally placed screens, thereby separating the crushed particles into different sizes. In practice, the large particles separated are fed into a collection box, which often requires operators to periodically remove the collection box to process the large particles. The overall operation is quite inconvenient. Therefore, there is an urgent need to propose a corresponding raw material mixing device for concrete slab production to solve the above problems.

A first opening and a second opening are provided on the side of the processing chamber near the side chamber. A guiding assembly for guiding materials is integrated between the upper part of the crushing assembly and the inner wall of the processing chamber. A screen plate is fixedly connected to the inner wall of the processing chamber below the crushing assembly, and the screen plate is inclined. A sealing assembly for sealing the second opening is provided inside the processing chamber.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A raw material mixing device for concrete slab production includes a processing chamber 1, a mixing component 2, and a crushing component 7. A side chamber 3 is fixedly connected to the outer wall of the processing chamber 1. A material tray 16 and a lifting component for vertical movement of the material tray 16 are integrated inside and outside the side chamber 3, respectively. A first opening 12 and a second opening 13 are opened on the side of the processing chamber 1 near the side chamber 3. A guiding component for guiding materials is integrated between the upper part of the crushing component 7 and the inner wall of the processing chamber 1. A screen plate 15 is fixedly connected to the inner wall of the processing chamber 1 below the crushing component 7, and the screen plate 15 is inclined. A sealing component for sealing the second opening 13 is provided inside the processing chamber 1.

[0025] Material is discharged from the feed inlet and crushed by the crushing component 7. The material falls onto the screen plate 15 and rolls along the inclined screen plate 15. During this process, material that meets the specifications will pass through the screen plate 15 into the mixing component 2, while larger particles will fall into the material tray 16. The rotating component 4 drives the sealing plate 14 to deflect at a specified angle, and the sealing plate 14 completes the closure of the second opening 13. The driving component 8 drives the transmission rod 9 to rotate. The transmission rod 9 drives the material tray 16 to rise to a specified height by engaging with the screw seat 10, until the bottom of the material tray 16 is flush with the guide plate 11. At this time, large particles will combine with the crushing component 7 along the bottom of the inclined material tray 16 and the guide plate 11 to achieve further crushing. The sealing plate 14 can temporarily block the subsequent large particles and prevent large particles from flowing back to the screen plate 15 through the second opening 13.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, a side plate 5 is fixedly connected to the outer wall of the side chamber 3. The side plate 5 is fixedly connected to the outer wall of the processing chamber 1 through a locking rod 6. The side plate 5 is integrated on the outer side of the side chamber 3. The side plate 5 is fixed to the processing chamber 1 through the locking rod 6. This ensures the stability of the working position of the side chamber 3. At the same time, the side chamber 3 can be easily disassembled and assembled to meet the needs of subsequent maintenance and cleaning, thereby improving the convenience of using the raw material mixing device for concrete slab production.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the sealing assembly includes a rotating component 4 fixedly connected to the outer wall of the processing chamber 1. A sealing plate 14 is fixedly connected to the output end of the rotating component 4. The rotating component 4 drives the sealing plate 14 to deflect at a specified angle, and the sealing plate 14 completes the closure of the second opening 13. The guiding assembly includes a guide plate 11 fixedly connected to the inner wall of the processing chamber 1. Both the guide plate 11 and the bottom of the material tray 16 are inclined. The bottom of the material tray 16 is flush with the guide plate 11. At this time, large particles of material will be combined with the crushing assembly along the inclined bottom of the material tray 16 and the guide plate 11. Component 7, the lifting assembly includes a drive component 8 fixedly connected to the outer wall of the side compartment 3, a transmission rod 9 fixedly connected to the output end of the drive component 8, and a screw seat 10 fixedly connected to the outer wall of the transmission rod 9 and the outer wall of the material tray 16. The drive component 8 drives the transmission rod 9 to rotate, and the transmission rod 9 drives the material tray 16 to rise to a specified height by screwing with the screw seat 10. The outer wall of the screw seat 10 is slidably connected to the inner wall of the side compartment 3 through a vertically set slide groove, so as to conform to the movement requirements of the material tray 16 and limit the axial deflection of the material tray 16.

[0028] Working principle: Material is discharged from the feed inlet and crushed by the crushing component 7. The material falls onto the screen plate 15 and rolls along the inclined screen plate 15. During this process, material that meets the specifications will pass through the screen plate 15 into the mixing component 2, while larger particles will fall into the material tray 16. The rotating component 4 drives the sealing plate 14 to deflect at a specified angle, and the sealing plate 14 completes the closure of the second opening 13. The driving component 8 drives the transmission rod 9 to rotate. The transmission rod 9, through its engagement with the screw seat 10, drives the material tray 16 to rise to a specified height until the bottom of the material tray 16 meets the guide. When plate 11 is flush with the ground, large particles will be fed into the crushing assembly 7 along the bottom of the inclined tray 16 and the guide plate 11 for further crushing. The sealing plate 14 can temporarily block the subsequent large particles and prevent them from flowing back to the screen plate 15 through the outlet 13. The side plate 5 is integrated on the outside of the side chamber 3. The side plate 5 is fixed to the processing chamber 1 by the locking rod 6, which ensures the stability of the working position of the side chamber 3. The side chamber 3 can be easily disassembled to meet the needs of subsequent maintenance and cleaning, thereby improving the ease of use of the raw material mixing device for concrete slab production.
