The axis of the second bevel gear 43 is located in the same straight line as the axis of the connecting shaft 3, and the first bevel gear 42 is meshed with the second bevel gear 43. When the driving motor 41 drives the first bevel gear 42 to rotate, the second bevel gear 43 rotates at the same time, thereby driving the rotation of the disc body 2.
[0036] Reference Figure 2 The upper surface of the disc body 2 is provided with a vertically arranged shell body 22, the shell body 22 is cylindrical, and a support frame 221 is fixed on the outer side of the shell body 22, and the support frame 221 is fixed on the ground. The support frame 221 enables the shell body 22 to be vertically arranged on the upper surface of the disc body 2, and the shell body 22 is located near the edge of the disc body 2, and the upper opening of the shell body 22 is convenient for the material to be put into the disc body 2, and a discharge port 222 is opened on one side of the shell body 22, and a vertically arranged scraper plate 223 is also fixed on the shell body 22, and the scraper plate 223 is fixed at one side edge of the discharge port 222, and the scraper plate 223 extends from a side near the discharge port 222 to the center of the disc body 2. When the disc body 2 rotates, the material slides toward the direction close to the shell body 22 under the centrifugal force of the disc body 2, and is finally scraped by the scraper plate 223 and flows out toward the discharge port 222, so as to realize the function of supplying materials to other equipment.
[0037] Reference Figure 3 and Figure 4The sleeve 21 is vertically fixed at the center of the disc body 2. A vertically arranged feeding channel 212 is provided in the sleeve 21. The feeding channel 212 has an inclined surface which gradually inclines upward from one side close to the center of the sleeve 21 to the surrounding areas. The lower end of the feeding channel 212 is connected with the middle section of the discharge channel 211 to promote the flow of materials into the discharge channel 211. The discharge channel 211 is horizontally provided in the sleeve 21, and one end of the discharge channel 211 passes through the side wall of the sleeve 21, so that the materials in the sleeve 21 can enter the disc body 2.

[0040] Guide plates 214 are fixed on the four edges of the sleeve 21. The guide plates 214 are gradually tilted downward from the side close to the sleeve 21 to the surrounding areas. When the material falls to the surrounding side of the sleeve 21, the guide plates 214 guide the material and flow it around, thereby reducing the accumulation of the material in the middle of the disc body 2.
