[0023] This application discloses a pneumatic material conveying device. (Refer to...) Figure 1-4A pneumatic material conveying device includes a conveying air pipe 1 and a material tank 2. One side of the conveying air pipe 1 is open, and the other side is connected to a blower 7. The blower 7 is connected to the conveying air pipe 1 via a fixing assembly, which includes a fixing ring 6 and multiple fixing bolts 8. The fixing ring 6 is sleeved on the side wall of the blower 7, and the multiple fixing bolts 8 are threaded onto the side wall of the fixing ring 6 and used to fix the fixing ring 6 to the side wall of the conveying air pipe 1. The material tank 2 is located above the conveying air pipe 1, and the bottom of the material tank 2 is fixedly connected to a discharge pipe 5. The bottom end of the discharge pipe 5 is fixedly connected to the conveying air pipe 1. Inside the feeding tube 5, a feeding plate 17 is rotatably mounted via a connecting shaft 18. A limiting assembly for restricting the connecting shaft 18 is provided on the feeding tube 5. The limiting assembly includes a mounting bracket 19 and a screw 20. The mounting bracket 19 is fixedly connected to the side wall of the feeding tube 5. The screw 20 is threadedly mounted on the side wall of the mounting bracket 19. One end of the screw 20 is fixedly connected to a first friction plate 22. Both ends of the connecting shaft 18 extend outwards through the side wall of the feeding tube 5. One end of the connecting shaft 18 is fixedly connected to a second friction plate 23 that cooperates with the first friction plate 22. The screw 20 is positioned away from the first friction plate 22. A knob 21 is fixedly connected to the end of the material tank 2. A feed hopper 3 is fixedly connected to the top of the material tank 2. A stirring mechanism for stirring materials is provided inside the material tank 2. The stirring mechanism includes a drive motor 15, an active stirring roller 9, and two driven stirring rollers 11. A fixing frame 4 is fixedly connected to the top of the material tank 2. The drive motor 15 is fixedly connected to the top side inside the fixing frame 4. The active stirring roller 9 and two driven stirring rollers 11 are rotatably mounted on the top side inside the material tank 2. Multiple active stirring rods 10 are fixedly connected to the side wall of the active stirring roller 9, and multiple driven stirring rods 12 are fixedly connected to the side wall of the driven stirring rollers 11. The drive motor... The output end of 15 is fixedly connected to the top end of the active stirring roller 9. The active stirring roller 9 is connected to the driven stirring roller 11 through a drive assembly. The drive assembly includes an active gear 13 and two driven gears 14. The active stirring roller 9 is movably connected to the top wall of the material tank 2 and the active gear 13 is provided thereafter. The top ends of the two driven stirring rollers 11 are movably connected to the top wall of the material tank 2 and the driven gears 14 are provided thereafter. The active gear 13 and the driven gears 14 mesh with each other. A support plate 16 is fixedly connected to the bottom of the inner side wall of the material tank 2. The bottom ends of the active stirring roller 9 and the driven stirring roller 11 are rotatably connected to the top of the support plate 16.

[0024] The implementation principle of the pneumatic material conveying device in this application embodiment is as follows: When the electrical components appearing in this application are used, they are all connected to an external power supply and control switch. When in use, the blower 7 is placed on one side of the conveying air pipe 1. The fixing ring 6 and the blower 7 can be fixed to the conveying air pipe 1 by multiple fixing bolts 8. The material enters the material tank 2 through the feed hopper 3. The stirring mechanism in the material tank 2 starts to work, and the drive motor 15 is started. Its output end drives the active stirring roller 9 to rotate. The active stirring rod 10 on the side wall of the active stirring roller 9 rotates accordingly to stir the material. Simultaneously, the driving gear 13 at the top of the active stirring roller 9 meshes with the driven gear 14 at the top of the driven stirring roller 11, thereby driving the driven stirring roller 11 to rotate synchronously. The driven stirring rod 12 on the side wall of the driven stirring roller 11 further enhances the stirring effect, prevents material from clumping, and ensures that the material is in a loose state for easy subsequent conveying. After the material is evenly stirred, it is necessary to control the amount of material entering the conveying air pipe 1. By rotating the knob 21, the screw 20 is driven to rotate. When the screw 20 rotates, it pushes the first friction plate 22 closer to or away from the second friction plate 23. When the second friction plate 22 and the second friction plate 23 are tightly fitted together, friction is generated, which restricts the rotation of the connecting shaft 18, thereby fixing the position of the feeding plate 17, controlling the opening and closing degree of the feeding pipe 5, and thus adjusting the amount of material entering the conveying air pipe 1. The blower 7 is started, and the airflow generated by the blower 7 forms an airflow channel in the conveying air pipe 1. The material enters the conveying air pipe 1 from the feeding pipe 5. Under the action of the airflow, the material is conveyed to the designated position along the conveying air pipe 1. The support plate 16 supports the active stirring roller 9 and the driven stirring roller 11, ensuring the stable operation of the stirring mechanism. During this process, the opening and closing of the feed plate 17 is precisely controlled through the cooperation of the screw 20, the first friction plate 22 and the second friction plate 23, thereby effectively controlling the amount of material entering the conveying air pipe 1, making the material more uniform during the conveying process, the discharge volume more stable, and improving the applicability of the device. The drive motor 15 drives the active stirring roller 9 and the driven stirring roller 11 to rotate, and the active stirring rod 10 and the driven stirring rod 12 stir the material, which can effectively prevent the material from clumping, keep the material in a loose state, and make it more conducive to pneumatic conveying, thus improving the conveying effect and efficiency.
