[0037] As a preferred embodiment, a hole 15 is provided between the two groups of inclined plates 11. The size of the hole 15 is consistent with that of the flat plate 12. The flat plate 12 can translate left and right on the slide rail 14 through the connecting shaft 13, so that the flat plate 12 can open and close the hole 15.

The rotating shaft 703 is the key component for controlling the opening and closing of the valve port 7. When the receiver 702 receives the signal from the electronic weighing sensor 607, it will drive the rotating shaft 703 to rotate, thereby driving the semicircular hinge 704 to rotate. The semicircular hinge 704 is made of metal material. When the two sets of semicircular hinges 704 are combined, the cross-section of the control valve port 7 should be the same size, so that it can completely seal the fall of the material of the control valve port 7 after receiving the signal from the electronic weighing sensor 607, thereby ensuring the accuracy of material weighing. The slot 705 is set on the connecting pipe 701, so that the semicircular hinge 704 will not conflict with the connecting pipe 701 when it is opened.

[0039] As a preferred embodiment, the probe 606 moves downward with the feed through the first baffle 602, so that the probe 606 changes the passing signal of the electronic weighing sensor 607. When the signal reaches the preset position, the electronic weighing sensor 607 rotates the semicircular hinge 704 through the receiver 702, so that the control valve port 7 is closed. Furthermore, when the probe 606 moves downward with the feed along with the first baffle 602, it changes the passing signal of the electronic weighing sensor 607, which means that the sensor can monitor the weight change of the feed in real time. Once the signal reaches the preset position, it means that the feed has reached the required weight. At this time, the electronic weighing sensor 607 will send an instruction through the receiver 702 to rotate the semicircular hinge 704 and close the control valve port 7. This design ensures that the amount of feed delivered each time reaches the predetermined weight, thereby achieving precise batching.

The dustproof box 5 is equipped with a weighing conveying mechanism 6. When the feed arrives, the flat plate 12 of the second baffle 603 is closed, so that the material can be accumulated on the first baffle 602. At the same time, the probe 606 will sense the weight change and transmit the signal to the electronic weighing sensor 607. The electronic weighing sensor 607 determines whether the control valve port 7 needs to be closed according to the preset weight value.
