[0021] Specifically, by the up and down sliding of multiple groups of pressing disc 16, the raw material deposited at the bottom of stirring drum 1 can be pushed outwards, and combined with the rotary motion of stirring rod 12, composite stirring is formed, effectively solving the problem of mixing blind area caused by one-way stirring of traditional stirring device, and the setting of tapered inclined surface can effectively avoid the accumulation of raw material on the end face of pressing disc 16.

[0023] Specifically, when reciprocating screw 10 rotates, screw sleeve 13 moves up and down along the threaded section, driving connecting rod 15 and pressing disc 16 to synchronously ascend and descend.

[0024] The rotating mechanism includes gear one 6, annular rack 7 and gear two 8, gear one 6 is coaxially fixedly connected with reciprocating screw 10 and located at the axis point of stirring drum 1, gear two 8 is coaxially fixedly connected with rotating rod 17 through a connecting rod, the connecting rod rotates and slides in sliding slot 5, gear two 8 and gear one 6 are meshed with each other, annular rack 7 is fixedly connected to the end surface of cover plate 2, and annular rack 7 and gear two 8 are meshed with each other.

[0025] Specifically, the meshing of gear one 6 and gear two 8, in combination with the annular rack 7, can make the rotating rod 17 rotate around the axis of the stirring drum 1 while self-rotating, forming planetary stirring movement.

[0026] The lower end surface of the cover plate 2 is fixedly connected with a limiting rod 11, a screw sleeve 13 is slidingly connected to the outer wall of the limiting rod 11, an end of the reciprocating screw 10 is fixedly connected with a limiting block 14, and the radius size of the limiting block 14 is greater than the radius of the reciprocating screw 10.
