[0023] An auxiliary spray port 11 is provided at the edge of the top plate of the shell 1 , and the auxiliary spray port 11 is located in the downward direction of the funnel-shaped feed port 6 .

[0024] The mud tray auxiliary separation mechanism includes a mud tray separation rod 12, an upper support rod 13, an upper limit coil spring 14, a lower support rod 17 and a lower limit coil spring; an upper separation rod clearance hole 15 is provided at the edge of the top plate of the shell 1, and the upper separation rod clearance hole 15 is located in the upward direction of the square discharge window 7; a lower separation rod clearance hole 16 is provided at the edge of the bottom plate of the shell 1, and the lower separation rod clearance hole 16 is located directly below the upper separation rod clearance hole 15; the mud tray separation rod 12 vertically passes through the upper separation rod clearance hole 15 and The lower separation rod has a clearance hole 16, and the mud tray separation rod 12 is in sliding contact with the feed tray 2 and the arc feed tooth 5; the top end of the mud tray separation rod 12 is fixedly connected to one end of the upper support rod 13, and the other end of the upper support rod 13 is fixedly connected to the outer end of the upper limit coil spring 14, and the inner end of the upper limit coil spring 14 is fixedly connected to the top plate of the outer shell 1; the bottom end of the mud tray separation rod 12 is fixedly connected to one end of the lower support rod 17, and the other end of the lower support rod 17 is fixedly connected to the outer end of the lower limit coil spring, and the inner end of the lower limit coil spring is fixedly connected to the bottom plate of the outer shell 1.

[0025] The lower support rod 17 is located directly below the upper support rod 13 , and the lower limit coil spring is located directly below the upper limit coil spring 14 .

[0026] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings:

[0027] First, the driving shaft 3 transmits the rotational power to the feed tray 2, driving the feed tray 2 to rotate in the housing 1. Then, the clay ore is fed into the housing 1 through the funnel-shaped feed port 6, and falls into the gap between the feed tray 2, the arc-shaped feed teeth 5 and the housing 1 by gravity. As the feed tray 2 rotates, the clay ore is pushed along the circumferential direction by the arc-shaped feed teeth 5.

[0028] When the mud ore moves to just below the auxiliary spray port 11, the moisture content of the mud ore is adjusted by spraying, and the mud ore with adjusted moisture content continues to be pushed along the circumferential direction by the arc stripping teeth 5. When the mud ore passes through the mud disc separation rod 12, the mud disc separation rod 12 always slides against the surface of the feed disc 2 and the arc stripping teeth 5. Therefore, the mud ore can be separated from the feed disc 2 and the surface of the arc stripping teeth 5 through the mud disc separation rod 12.

[0029] During the sliding process of the mud pan separation rod 12 against the surface of the feed pan 2 and the arc feed tooth 5, the spring force output by the upper limit coil spring 14 and the lower limit coil spring can ensure the reliability of the fit between the mud pan separation rod 12 and the surface of the feed pan 2 and the arc feed tooth 5, and the deformation of the upper limit coil spring 14 and the lower limit coil spring can ensure the conformal movement of the mud pan separation rod 12.

[0030] When the mud ore passes over the mud tray separation rod 12, it will be pushed to the square discharge window 7 by the continuously rotating feeding tray 2 and the arc stripping teeth 5. Under the action of gravity, the mud ore will continuously fall from the square discharge window 7 to the guide chute 8 below. A small amount of mud ore attached to the upper and lower surfaces of the feeding tray 2 and the arc stripping teeth 5 will also be blocked when passing through the upper baffle plate 9 and the lower baffle plate 10, and will move toward the square discharge window 7 along the upper baffle plate 9 and the lower baffle plate 10 as the feeding tray 2 rotates, and will finally fall onto the guide chute 8 under the action of weight, and finally the guide chute 8 will feed the mud ore directly to the ball mill or magnetic separator, thereby realizing direct feeding of mud ore and eliminating the traditional drying process.

[0031] The solutions in the embodiments are not intended to limit the protection scope of the present invention. All equivalent implementations or changes that do not deviate from the present invention are included in the protection scope of the present invention.
