[0024] Specifically, the mixing drum 11 of the mixer 1 is a cylindrical structure with an open top and a closed bottom. Three supporting legs are provided at the bottom of the mixing drum 11 for supporting the mixing drum 11 on the ground. The mixing mechanism is rotatably arranged in the mixing drum 11. A driving assembly is provided at the bottom of the mixing drum 11. The driving end of the driving assembly is transmission-connected with the mixing mechanism in the mixing drum 11, and is used to drive the mixing mechanism to rotate in the mixing drum 11 to mix the materials in the mixing drum 11. The connection cover 2 of the material discharge assembly is connected to the top opening of the mixing drum 11. When the cover plate 3 is closed, the top opening of the mixing drum 11 can be closed, so that dust will not escape from the inside of the mixing drum 11 when the mixing drum 11 is working, thereby ensuring the health of the operators. At the same time, when the bagged powdered material is put into the mixing drum 11, the bagged material is placed on the metal mesh 8 of the unloading assembly, and after the cover plate 3 is covered, the bagged material can be automatically broken by the joint action of the spikes 71 on the rotating plate 7 and the serrated ring on the metal mesh 8. The powdered material after the bag is broken falls into the mixing drum 11 through the metal mesh 8, and the broken bag is retained above the metal mesh 8 through the filtering effect of the metal mesh 8. The broken bag can be taken out by opening the cover plate 3.

[0025] In order to facilitate the connection between the connection cover 2 and the mixing drum 11, a circular plate 21 is fixedly provided at the bottom end of the connection cover 2, and a connecting sleeve 22 is fixedly provided at the bottom of the circular plate 21. The connecting sleeve 22 is sleeved on the outside of the mixing drum 11, and the circular plate 21 is supported on the top of the mixing drum 11. Specifically, the connection cover 2 is a cylindrical structure, and the inner diameter of the connection cover 2 is smaller than the inner diameter of the mixing drum 11, so that the material after the bag is broken can completely enter the mixing drum 11; the inner diameter of the circular plate 21 is equal to the inner diameter of the connection cover 2, and the circular plate 21 is fixedly connected to the bottom end of the connection cover 2 by welding; the inner diameter of the connecting sleeve 22 is larger than the outer diameter of the mixing drum 11, and the connecting sleeve 22 is fixedly connected to the lower surface of the circular plate 21 by welding; the connection cover 2, the circular plate 21 and the connecting sleeve 22 are all coaxially arranged. By setting as above, the connection cover 2 can be directly sleeved on the top of the mixing drum 11 of the mixer 1 through the connecting sleeve 22, which facilitates the connection between the unloading assembly and the mixer 1, and the unloading assembly is easy to install and disassemble. In this embodiment, a rubber pad 23 is fixed on the inner wall of the connecting sleeve 22. Specifically, the rubber pad 23 is a cylindrical structure, the outer diameter of the rubber pad 23 matches the inner diameter of the connecting sleeve 22, and the inner diameter of the rubber pad 23 matches the outer diameter of the mixing drum 11. In specific implementation, the rubber pad 23 can be bonded and fixed to the inner circumferential wall of the connecting sleeve 22 by an adhesive. By providing the rubber pad 23, the noise generated by the mutual friction between the mixer 1 and the connecting sleeve 22 during vibration can be reduced when the mixer 1 is working, and it also has a certain sealing effect to prevent the dust in the mixing drum 11 from escaping.

[0026] Furthermore, the sawtooth ring includes a large sawtooth ring 81 and a small sawtooth ring 82 which are arranged concentrically, the lower ends of the large sawtooth ring 81 and the small sawtooth ring 82 are fixed on the upper surface of the metal mesh 8, and the upper ends of the large sawtooth ring 81 and the small sawtooth ring 82 are uniformly distributed with a plurality of saw teeth along the circumferential direction.
