[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3An embodiment of this utility model provides a double-gate linkage anti-leakage mechanism for a pediatric granule metering hopper, comprising a feeding hopper 1, a hydraulic cylinder 2 fixedly connected inside the feeding hopper 1, a connecting block 3 connected to the output end of the hydraulic cylinder 2, an opening and closing assembly provided on the outer wall of the connecting block 3, the outer wall of the opening and closing assembly being provided on the outer wall of the feeding hopper 1, a metering hopper body 6 being provided below the feeding hopper 1, a motor 7 fixedly connected inside the feeding hopper 1, a rotating assembly provided at the output end of the motor 7, a swing block 10 provided at the tooth end of the rotating assembly, a hammer 11 fixedly connected to the outer wall of the swing block 10, a fixed block 12 rotatably connected to the outer wall of the swing block 10, the outer wall of the fixed block 12 being fixedly connected to the outer wall of the feeding hopper 1, the outer wall of the rotating assembly being rotatably connected to the inside of the fixed block 12, a rotating wheel 13 fixedly connected to the outer wall of the rotating assembly, and a transmission assembly provided on the outer wall of the rotating wheel 13.

[0026] Specifically, by activating the hydraulic cylinder 2, the connecting block 3 moves, further driving the opening and closing assembly to open or close, thus discharging the pediatric granules from the hopper 1. By activating the motor 7, the rotating assembly rotates. Due to the special shape of the swing block 10, when the rotating assembly rotates, it drives the swing block 10 to reciprocate. When the swing block 10 reciprocates, the fixing action between the swing block 10 and the hammer 11 drives the hammer 11 to rotate, further striking the side wall of the hopper 1. When the rotating assembly rotates, the fixing action between the rotating assembly and the rotating wheel 13 drives the rotating wheel 13 to rotate, further driving the transmission assembly to rotate. The rotation of the transmission assembly drives the hammer 11 on the other side of the hopper 1 to rotate. The hammer 11 strikes the hopper 1, thus preventing the pediatric granules from sticking to the inner wall of the hopper 1 and improving the accuracy of discharging.

[0027] Reference Figures 2-4 The opening and closing assembly includes a rotating plate 4, the interior of which is rotatably connected to the outer wall of the connecting block 3. A sealing door 5 is rotatably connected to the interior of the rotating plate 4, and the outer wall of the sealing door 5 is located on the outer wall of the hopper 1. The rotating assembly includes a transmission rod 8, the outer wall of which is fixedly connected to the output end of the motor 7. A gear 9 is fixedly connected to the outer wall of the transmission rod 8, and the tooth end of the gear 9 is located on the outer wall of the swing block 10. The outer wall of the transmission rod 8 is rotatably connected to the interior of the fixed block 12, and the outer wall of the transmission rod 8 is fixedly connected to the interior of the first rotating wheel 13. The transmission assembly includes a conveyor belt 14, the outer wall of which is located on the outer wall of the first rotating wheel 13, and a second rotating wheel 15 is located on the outer wall of the conveyor belt 14.

[0028] Specifically, when the connecting block 3 moves, it will drive the rotating plate 4 to rotate, which will further drive the sealing door 5 to open or close, thus realizing material discharge. By turning on the motor 7, the transmission rod 8 will rotate, which will further drive the gear 9 to rotate, thus driving the swing block 10 to swing back and forth. When the transmission rod 8 rotates, through the fixing action of the transmission rod 8 and the first rotating wheel 13, the first rotating wheel 13 will rotate, which will further drive the conveyor belt 14 to rotate, thus driving the second rotating wheel 15 to rotate.

[0029] Reference Figures 3-5 A sealing strip 16 is provided on the outer wall of the sealing door 5. The outer wall of the sealing strip 16 is provided on the side wall of the hopper 1. A connecting plate 17 is fixedly connected to the outer wall of the sealing strip 16. The outer wall of the connecting plate 17 is slidably connected to the inside of the sealing door 5. A sliding component is provided inside the connecting plate 17. A housing 21 is slidably connected to the outer wall of the sliding component. The outer wall of the housing 21 is fixedly connected to the outer wall of the sealing door 5. A spring 20 is provided on the outer wall of the sliding component. The outer wall of the spring 20 is provided inside the housing 21.

[0030] Specifically, the tight fit of the sealing strip 16 prevents the granules from leaking out of the gaps in the sealing door 5. When the sealing strip 16 needs to be removed, first pull the sliding component to make it slide inside the housing 21. After the sliding component slides to the appropriate position, rotate the sliding component to fix it inside the housing 21, thereby removing the limit on the connecting plate 17. Since the connecting plate 17 and the sealing strip 16 are fixedly connected, the sealing strip 16 can be quickly removed, preventing the sealing strip 16 from wearing out after long-term use and causing the granules to leak out.

[0031] Reference Figure 4 and Figure 5 The sliding assembly includes a sliding column 18, the outer wall of which is slidably connected to the inside of the connecting plate 17, a connecting column 19 fixedly connected to the outer wall of the sliding column 18, and the outer wall of the sliding column 18 slidably connected to the inside of the housing 21. The outer wall of the spring 20 is disposed on the outer wall of the sliding column 18, and the outer wall of the connecting column 19 is slidably connected to the inside of the housing 21. A groove 22 is provided inside the housing 21, and the connecting column 19 is slidably connected to the inside of the housing 21 through the groove 22.

[0032] Specifically, by pulling the connecting column 19, the sliding column 18 is moved. The spring 20 is used to reset the sliding column 18. By sliding the sliding column 18, the limiting of the connecting plate 17 is removed. The slide groove 22 is used to limit the movement trajectory of the connecting column 19, and further limit the sliding column 18.

[0033] Reference Figure 5 Spring 20 is made of nickel alloy;

[0034] Specifically, the excellent toughness and fatigue resistance of nickel alloy enable spring 20 to maintain good rebound after long-term operation.

[0035] Working principle: By activating the hydraulic cylinder 2, the connecting block 3 is moved, which in turn drives the rotating plate 4 to rotate. When the rotating plate 4 rotates, it drives the sealing door 5 to open or close, thereby controlling the discharge of children's granules. Activating the motor 7 drives the transmission rod 8 to rotate inside the fixed block 12. When the transmission rod 8 rotates, it drives the gear 9 to rotate, which in turn drives the swing block 10 to rotate back and forth. When the swing block 10 rotates back and forth, it drives the hammer 11 to rotate back and forth, thereby striking the side wall of the hopper 1. This prevents the children's granules from sticking to the inner wall of the hopper 1 during discharge, thus avoiding metering deviation.

[0036] By installing a sealing strip 16 on the surface of the sealing door 5, the overall sealing performance of the sealing door 5 is improved, preventing leakage of granules. When the sealing strip 16 wears out and needs to be replaced, first pull the connecting column 19 to drive the sliding column 18 to slide inside the outer shell 21. While the sliding column 18 slides inside the outer shell 21, it will compress the spring 20. After the connecting column 19 moves to the appropriate position, rotate the connecting column 19 so that it is fixed inside the outer shell 21 through the sliding groove 22, further realizing the removal of the limit on the connecting plate 17. Through the fixing effect of the connecting plate 17 and the sealing strip 16, the limit on the sealing strip 16 is removed, which facilitates the quick disassembly and replacement of the sealing strip 16 by the operators later.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
