[0025] Please see Figures 1 to 5 An embodiment of this utility model is provided: a screw conveying metering bin device, including a support mechanism 1 and a conveying mechanism 2 and a weighing mechanism 3 disposed on the support mechanism 1. The support mechanism 1 includes a support frame 11 and a fixed seat 12 disposed on one side of the support frame 11. Multiple casters 13 are installed at the bottom of the support frame 11.

[0026] The conveying mechanism 2 includes a spiral conveying drum 21, a fixed housing 22 fixed to the top of the spiral conveying drum 21, and a motor 23 fixed to the fixed housing 22. Two protrusions are provided at the bottom of the spiral conveying drum 21, and both protrusions abut against the support frame 11, allowing the support frame 11 to support the conveying mechanism 2 and ensure the stability of the conveying mechanism 2 structure. The fixed housing 22 is a hollow cavity structure, and the cavity of the fixed housing 22 communicates with the cavity of the spiral conveying drum 21. A driving wheel 24 and a driven wheel 25 are provided inside the fixed housing 22, connected by a belt. The driving wheel 24 is fixedly connected to the output end of the motor 23, and a conveying rod is fixedly connected to the driven wheel 25. 26. A spiral blade 27 is provided on the conveying rod 26. The spiral conveying cylinder 21 is a cavity structure with openings at both ends and a hollow interior. The conveying rod 26 and the spiral blade 27 are both located inside the cavity of the spiral conveying cylinder 21. Both ends of the conveying rod 26 are rotatably connected to the spiral conveying cylinder 21, so that the conveying rod 26 can operate stably. The conveying mechanism 2 also includes a corner tube 28, which is fixedly connected to the top of the spiral conveying cylinder 21. The corner tube 28 serves to change the material conveying direction, so that the material is conveyed vertically downward. The conveying mechanism 2 also includes a feeding hopper 29, which is fixedly connected to the bottom of the spiral conveying cylinder 21. The feeding hopper 29 has an opening for feeding materials.

[0027] The weighing mechanism 3 includes a hopper 31, which is fixed on a fixed base 12. A flexible hose 32 is fixedly connected to the hopper 31. The bottom of the corner pipe 28 passes through the flexible hose 32 and enters the cavity of the hopper 31. A weighing module 33 is fixed in the circumferential direction of the hopper 31. The technical principle of the weighing module 33 is the prior art. For reference, see the patent application number CN202321733718.2 - Weighing Module in Automatic Dispensing Device. A discharge pipe 34 is fixedly connected to the bottom of the hopper 31. A valve 35 is provided on the discharge pipe 34. The valve 35 can be a pneumatic butterfly valve.

[0028] Please refer to the following: Figures 1 to 5 In operation, the drive motor 23 drives the drive wheel 24 to rotate, causing the driven wheel 25 to rotate under the action of the belt. The driven wheel 25 drives the conveying rod 26 and the spiral blade 27 to rotate. By feeding material into the opening on the feeding hopper 29, the material enters the feeding hopper 29 and is slowly conveyed upward under the action of the spiral blade 27. Finally, the material is sent to the top of the spiral conveying cylinder 21 and enters the corner tube 28, and finally enters the cavity of the hopper 31. The weighing module 33 accurately weighs the material in the hopper 31. When the material reaches the required weight, the motor 23 stops working. Then, the valve 35 opens the discharge pipe 34, thereby discharging the specified weight of material.
