When the ring drum 40 is moved down so that the upper end of the inner ring guide portion 421 is level with the upper end surface of the second packing auger 23, the upper end of the outer ring guide portion 431 is lower than the upper end surface of the first packing auger 22, and the lower end of the guide outer portion 4511 blocks the material on the upper end of the first packing auger 22, so that the inner ring guide portion 421 releases the material on the second packing auger 23 and makes the material on the first packing auger 22 not pass through the discharging passage 24 downward, and the material on the second packing auger 23 passes through the discharging passage 24 downward and collides with the guide portion 451 to be dispersed at the inner and outer sides of the guide portion 451.

Therefore, the synchronous rotation of the mixing barrel 20 and the annular barrel 40 and the short-frequency reciprocating movement of the annular barrel 40 on the mixing barrel 20 can realize that two materials can be alternately and rapidly fed into the discharging channel 24 until the materials are discharged from the discharging hole at the bottom of the mixing barrel 20, so that the two materials can be quickly premixed.

With continued reference to fig. 12-15, the upper end of the cover 30 is not provided with a telescopic member, instead, the upper end of the cover 30 is fixedly provided with a guide driving member 33, the guide driving member 33 is in an annular cylindrical structure, the inner circumferential wall of the guide driving member 33 is provided with a guide chute, the guide chute is provided with a spiral ascending section 331 and a vertical section 332, the upper end and the lower end of the vertical section 332 are respectively communicated with the head end and the tail end of the spiral ascending section 331, the cover 30 is coaxially and rotatably provided with a driving rod 34 with the mixing barrel 20, one end of the driving rod 34 extending downwards into the mixing barrel 20 is fixedly connected with a connecting rod 41 in a coaxial manner, the periphery of one end of the driving rod 34 extending upwards out of the cover 30 is provided with a guide rod 341, and the guide rod 341 can slide in the guide chute.

Therefore, when the mixing barrel 20 rotates, the annular barrel 40 rotates synchronously with the mixing barrel 20, and the connecting rod 41 drives the driving rod 34 to rotate synchronously, so that under the cooperation of the guide rod 341 and the guide chute, when the guide rod 341 slides on the spiral ascending section 331, the annular barrel 40 can move upwards while rotating, when the guide rod 341 slides on the vertical section 332, the annular barrel 40 can move downwards rapidly under the assistance of self weight, thus forming a cycle of moving upwards and downwards, wherein in order to avoid the clamping of the guide rod 341 at the joint of the spiral ascending section 331 and the vertical section 332, the driving motor 202 can be controlled to operate intermittently, namely, the driving motor 202 stops driving every time the guide rod 341 slides upwards to the joint of the spiral ascending section 331 and the vertical section 332, and when the guide rod 341 slides down to the bottom end of the vertical section 332, the driving motor 202 is started, so that the annular barrel 40 moves downwards to the lower end of the vertical section 332 rapidly under the assistance of self weight, the annular barrel 40 can generate vibration at the lower end of the vertical section 332, and the annular barrel 40 can vibrate and mix materials favorably.

Wherein in the up-down circulation moving process of the annular barrel 40, the inner ring flow guiding portion 421 can perform short-frequency and intermittent blocking or releasing on the material located on the second auger 23, meanwhile, the outer ring flow guiding portion 431 can perform short-frequency and intermittent releasing or blocking on the material located on the first auger 22, so that the mixing frequency of the material in the downward moving process of the discharging channel 24 is increased, and meanwhile, the annular barrel 40 can perform short-frequency reciprocating movement in the up-down direction while synchronously rotating along with the mixing barrel 20 without the assistance of the telescopic piece, and therefore, a better material premixing effect is achieved after the material is discharged from a discharge hole at the bottom of the mixing barrel 20.
