[0108] As shown in Figure 2 、 7 The driving mechanism can include a transmission nut 62, a transmission screw 63 and a hand wheel 64;

[0109] The outer peripheral portion of the valve plate component 59 is in sliding tight fit with the inner wall of the discharge passage 60;

[0110] The transmission nut 62 is rotationally connected in the discharge seat 58;

[0111] One end of the transmission screw 63 is fixedly connected to the valve plate component 59, and the transmission screw 63 is also in threaded cooperation with the transmission nut 62;

[0112] The hand wheel 64 is connected to the transmission nut 62 and is used to drive the transmission nut 62 to rotate, and then drives the transmission screw 63 to move through the threaded cooperation, and then drives the valve plate component 59 to move in the discharge passage 60.

[0113] Specifically, the discharge channel 60 is further provided with a second bellows 65, the second bellows 65 is sleeved on the outside of the transmission screw 63, one end of the second bellows 65 is connected with the valve plate component 59, the other end of the second bellows 65 is connected with the discharge seat 58.

[0114] In the embodiment, the valve plate component 59 and the discharge channel 60 are in close fit, so the friction is large, the friction between the valve plate component 59 and the discharge channel 60 can limit the valve plate assembly and the transmission screw 63 from rotating with the transmission nut 62.

[0115] In summary, first, the material to be mixed is loaded into the inner cavity 2 of the tank body 1, since the rotary shaft 3 and the central shaft 4 of the tank body 1 are at an angle, when the tank body 1 is driven to rotate around the rotary shaft 3, the material in the inner cavity 2 can be turned and mixed, the rotation of the tank body 1 around the rotary shaft 3 drives the material in the inner cavity 2 to turn and mix, there is no mixing dead angle, the material can be quickly and evenly mixed, the mixing efficiency is improved, the time for the material to be fully mixed and evenly distributed is saved, the efficiency is higher and safer.

[0116] The above specific embodiments, the technical problems solved by the utility model, technical scheme and beneficial effects are further described in detail, it should be understood that the above-mentioned is only the specific embodiment of the utility model and does not limit the utility model, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
