When the material passes through the funnel 94, the first inclined surfaces set on both sides of the guide block 95 installed inside the funnel 94 guide the material in the funnel 94, which can better prevent the material from being piled up in one place after falling into the receiving tank, thereby affecting the ratio of the raw materials. When other receiving tanks are needed to put materials, the cover 4 is rotated to drive the funnel 94, the guide block 95 and the partition plate 96 to rotate to other receiving tanks where the raw materials need to be put for putting. At the same time, the second inclined surface set at the bottom of the guide block 95 can better flatten the accumulated raw materials and prevent the first inclined surface from shoveling out of the current receiving tank when flattening the raw materials.
