The mixing hopper 21 can be shaken back and forth to shake the material in the mixing hopper 21, so that the material can move up and down in the mixing hopper 21, ensuring that the material can be stirred, thereby improving the mixing effect of the material.

[0027] Furthermore, a storage structure 3 is installed on the front side of the second mixing component 11, and the storage structure 3 includes a storage box 31, which is installed on the outside of the extrusion cylinder 12. An inclined groove 32 is provided on the inner bottom surface of the storage box 31, and a discharge trough 33 is provided on the front of the storage box 31. A baffle 34 is movably installed on the inner side of the discharge trough 33, and a pull rod 35 is fixedly connected to the top surface of the baffle 34. The material is extruded into the storage box 31 through the extrusion cylinder 12, and the material moves toward the discharge trough 33 along the inclined groove 32.

Since the fixed frame 27 fixedly connected to the bottom surface of the mixing hopper 21 is rotatably connected with the connecting frame 28 fixedly installed on the top surface of the first mixing component 1, when the mixing hopper 21 moves, it will drive the fixed frame 27 to rotate on the connecting frame 28, so that the mixing hopper 21 moves in an arc trajectory in the front and back directions, shakes the materials in the mixing hopper 21, and enables the materials to move up and down in the mixing hopper 21, ensuring that all materials can be stirred, thereby improving the mixing effect of the materials;
