The feed inlet in the middle of the hopper support box 12 is controlled by a feeding valve 11. The upper cylindrical section 2 and the lower cylindrical section 3 are respectively installed at the upper and lower ends of the frame 1. The middle cylindrical section 13 is installed between the upper cylindrical section 2 and the lower cylindrical section 3 and is connected to each other. Three lifting lugs are evenly distributed along the circumference on the bottom surface of the upper cylindrical section 2, and the lifting lugs are connected to the weighing part of the middle cylindrical section 13 through a weighing sensor 5. The discharge port at the lower end of the middle cylindrical section 13 is controlled by a flap 18.

[0027] In this embodiment, frame 1 is a rectangular frame with four vertical bars extending downward to form four supporting legs, and three brackets arranged in a triangular pattern on the inner side of the upper end.

[0028] In this embodiment, the upper section 2 of the cylinder is a plate-shaped structure with an upper through hole in its middle and an upper connecting ring communicating with the upper through hole in the middle of its bottom surface. The lower section 3 of the cylinder is a plate-shaped structure with a lower through hole in its middle and a lower connecting ring communicating with the lower through hole in the middle of its bottom surface.

[0029] In this embodiment, the weighing sensor 5 is equipped with connectors 4 at its upper and lower ends, respectively.

[0030] In this embodiment, the discharge port of the hopper 10 is an arc-shaped square box that extends into the hopper support box 12. The hopper support box 12 has a through hole in the middle through which a shaft 8 passes. The two ends of the shaft 8 are equipped with bearings 15 and bearing seats 20, and are also equipped with connecting rod 6, connecting rod 7, cylinder 16 and cylinder accessory 17.

[0031] In this embodiment, bearing housings 14 are symmetrically arranged on both sides of the middle section 13 of the cylinder. Two shafts 9 are connected between the two bearing housings 14, and a flap 18 for controlling unloading is welded on the shafts 9. Bearings 15 and bearing seats 19 are assembled at both ends of the shafts 9. A cylinder 16 and a cylinder accessory 17 are connected to the bearing housings 14.

[0032] In this embodiment, a double-layer distribution box is also included, which contains a programmable controller, a touch screen, a weighing instrument, a leakage current switch, a relay, and an RS485 to RS232 communication converter. The output of the weighing sensor is connected to control the weighing instrument in the distribution box; the touch screen acts as the host computer, and the programmable controller and the weighing instrument act as slave computers. The cylinder responds immediately, and all control functions are managed by the touch screen.

[0033] Before weighing, the operator first selects the parameter setting button on the touch screen, and then... Figure 5 On the screen, select either the delivery mode or the receiving mode, and set the batch interval and delayed unloading time. Set the feeding and unloading timeout alarm times according to actual needs. Return to the running screen, select the recipe button, and the following will appear. Figure 6 On the screen, set the total quantity, single-bucket set value, and small lead time in the text box. Return to the running screen. Figure 7 Once all parameters are set, the target set value and the current real-time weight in the hopper will appear simultaneously on the running screen.

[0034] When the knob is switched to manual mode, manual feeding and unloading are possible. During manual feeding, relay KA3 engages, triggering the corresponding feeding cylinder and opening the feeding flap. During manual unloading, relay KA4 engages, triggering the corresponding unloading cylinder and opening the unloading flap. When the knob is switched to automatic mode and the "automatic start" button is pressed, the feeding flap immediately opens to begin feeding, with the weight displayed in real-time. Feeding stops when the displayed weight approaches the single-hopper set value and the difference is close to the small lead time. After the delayed unloading time, unloading begins, completing one automatic weighing cycle. In receiving mode, the automatic weighing task will repeat continuously. In shipping mode, a two-hopper system is set, displaying both total weight and single-hopper weight. The single-hopper total weight is automatically set after each shipment, achieving automatic batch operation.

[0035] During operation, it can be directly controlled via the touchscreen. The interface is intuitive and includes start, stop, and reset buttons, as well as manual / automatic switching, and delivery and receiving modes. Users can set the material feeding interval, total weighing volume, and single-bucket setpoint, enabling fully automatic weighing as needed.
