[0009] The hopper is arranged below the electric discharge valve I and corresponds to the notch. An electric discharge valve II is installed at the bottom of the hopper.

[0010] A scraper is arranged at the top of the hopper. The scraper is installed at the bottom of the electric discharge valve I and is used to scrape the raw materials protruding from the hopper.

[0011] The linear driving component is installed on the support cylinder and is connected to the hopper for driving the hopper to move horizontally.

[0012] The N hoppers have different volumes and are used to respectively receive and store the quantitative raw materials from the bin.

[0013] Preferably, a material guiding plate is installed at the inner bottom of the support cylinder.

The device has a simple structure, reduces the expenditure of the enterprise, and lowers the maintenance difficulty.

[0019] 2. By controlling the elongation of the electric push rod, the hopper slowly moves towards the notch. At the same time, during the movement of the hopper, the scraper scrapes off the raw materials protruding from the hopper, so that the amount of raw materials received by the hopper meets the specific production ratio requirements. By moving the hopper above the belt conveyor and opening the second electric discharge valve, the raw materials in the hopper fall onto the belt conveyor, facilitating the belt conveyor to convey the raw materials.

An electric discharge valve 11 is installed at the bottom discharge port of the bin 1. By opening the electric discharge valve 11, the raw materials in the bin 1 are discharged through the electric discharge valve 11.

[0030] The support cylinder 2 is installed at the bottom of the bin 1 to support the bin 1. A notch 22 is provided on the side of the support cylinder 2 corresponding to the belt conveyor 5.

[0031] The hopper 3 is arranged below the electric discharge valve 11 and corresponds to the notch 22. An electric discharge valve 31 is installed at the bottom of the hopper 3. By opening the electric discharge valve 31, the raw materials in the hopper 3 are discharged through the electric discharge valve 31.

[0032] A scraper 8 is arranged at the top of the hopper 3. The scraper 8 is installed at the bottom of the electric discharge valve 11 and is used to scrape the raw materials protruding from the hopper 3 so that the amount of raw materials received by the hopper 3 meets the specific production ratio requirements.

[0033] The linear drive component is an electric push rod 6 installed on the outer side of the support cylinder 2. The telescopic end of the electric push rod 6 passes through the wall of the support cylinder 2 and is connected to the hopper 3. By controlling the elongation of the electric push rod 6, the hopper 3 is driven to move horizontally so that the hopper 3 corresponds to the electric discharge valve 11 or the belt conveyor 5.

[0034] The volumes of the four hoppers 3 are designed according to the preset raw material distribution ratio. Therefore, the volumes of the four hoppers 3 are different.

[0037] During production, each electric discharge valve 11 is opened to allow the raw materials in each silo 1 to fall into each measuring hopper 3 respectively;

[0038] After the measuring bucket 3 is filled with raw materials, the corresponding electric discharge valve 11 is closed, and the corresponding electric push rod 6 is controlled to extend, so that the measuring bucket 3 slowly moves toward the direction of the notch 22. At the same time, during the movement of the measuring bucket 3, the scraper 8 scrapes off the raw materials protruding from the measuring bucket 3, so that the amount of raw materials received by the measuring bucket 3 meets the specific production ratio requirements;
