[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. While the motor 1 drives the stirrer to rotate in the present utility model, it can also drive the sleeve and the sleeve rod fixedly connected to the outside of the ring to rotate together. The rotation of the sleeve rod will also drive the roller to do a circular motion. When the roller rolls onto the convex block, at this time, the sleeve rod will shrink into the sleeve and compress the spring. When the roller rolls away from the convex block, at this time, the sleeve rod will extend out of the sleeve under the elastic return of the spring. In this way, it can drive the motor 2, the rotating shaft and the spiral blade to do horizontal reciprocating movement, thereby increasing the stirring range of the material, and then ensuring the thorough mixing of the material, effectively avoiding the problem that due to the limited stirring range of the device and difficult to adjust, the material is prone to uneven mixing, thus reducing the mixing effect of the material.

[0016] 2. When the roller rolls away from the convex block in the present utility model, under the elastic return of the spring, the roller will automatically reset and hit the cylinder wall. After being hit, the cylinder wall will vibrate, thereby being able to shake off the material adhering to the surface of the cylinder wall, and then achieving the purpose of preventing the material from sticking, with strong practicability.

[0017] 3. During the process of the two sets of sleeve rods moving towards or away from each other in the present utility model, by using the hinged action between the connecting seat, the vertical rod and the connecting rod, it can drive the connecting plate to do vertical reciprocating movement, thereby being able to drive the stirrer to do vertical reciprocating movement to further increase the stirring range of the material, and then further ensuring the thorough stirring of the material.

[0028] In the embodiment of the present application, the implementation principle of a double - helix conical mixer is as follows: First, materials are added into the cylinder body 1 through the feeding pipe 2. Then, the first motor 113 and two groups of second motors 114 are started. The first motor 113 can drive the stirrer 102 to rotate to stir the materials, and the second motor 114 can drive the spiral blade 107 to rotate to stir the materials. At the same time, during the process of driving the stirrer 102 to rotate by the first motor 113, it can also drive the sleeve 104 and the sleeve rod 105 fixedly connected to the outside of the ring 103 to rotate together.

And when the roller 108 rolls away from the convex block 109, under the elastic return of the spring 106, the roller 108 will automatically reset and hit the cylinder wall. After being hit, the cylinder wall will vibrate, so that the materials attached to the surface of the cylinder wall can be shaken off, thereby achieving the purpose of preventing material adhesion. At the same time, during the process of the two sleeve rods 105 moving towards or away from each other, by using the hinge action between the connecting seat, the vertical rod 110 and the connecting rod 111, it can drive the connecting plate 101 to make vertical reciprocating movements, so as to drive the stirrer 102 to make vertical reciprocating movements to further increase the stirring range of the materials, and further ensure the thorough stirring of the materials. Finally, open the valve to discharge the mixed materials through the discharge pipe 3.
