[0027] In some implementations of this embodiment, the mixing assembly includes a driving mechanism and a mixing mechanism both disposed in the mixing tank 2 , and the driving mechanism is used to control the movement of the mixing mechanism in the mixing tank 2 .

[0028] In some implementations of the present embodiment, the driving mechanism includes a forward and reverse driving member 5 arranged on the mixing tank 2, a screw rod 6 rotatably arranged in the mixing tank 2 and a nut 7 connected to the screw rod 6, the screw rod 6 is transmission-connected to the forward and reverse driving member 5, and the forward and reverse driving member 5 is used to control the rotation of the screw rod 6; the mixing mechanism is arranged on the nut 7, and a first limiting mechanism for limiting the rotation of the nut 7 is arranged on the mixing mechanism; a second limiting mechanism for limiting the stroke of the nut 7 is arranged on the screw rod 6.

[0029] In this embodiment, the driving mechanism is designed as such a structure, which is convenient for controlling the mixing mechanism to move up and down in the mixing tank 2, thereby mixing the liquid in the mixing tank 2. When the forward and reverse driving member 5 drives the screw rod 6 to rotate forward or reverse, the nut 7 moves up and down on the screw rod 6, thereby driving the mixing mechanism to move up and down. When the screw rod 6 rotates to drive the nut 7 to rotate, the nut 7 cannot rotate due to the presence of the first limiting mechanism, so that the nut 7 can move up and down on the screw rod 6.

[0030] In some implementations of this embodiment, the mixing mechanism includes a plurality of first connecting rods 8 arranged in an array in the circumferential direction of the nut 7 , and a plurality of second connecting rods 9 are arranged at intervals between two adjacent first connecting rods 8 .

[0032] In some implementations of this embodiment, the first limiting mechanism includes a limiting rod 10 arranged on one of the first connecting rods 8 and a groove 11 opened on the inner wall of the mixing tank 2, the extension direction of the groove 11 is the same as the moving direction of the nut 7, and the free end of the limiting rod 10 is inserted into the groove 11.

[0033] In this embodiment, the limiting rod 10 cooperates with the groove 11 to prevent the nut 7 from rotating when the screw rod 6 rotates.

[0034] In some implementations of this embodiment, the second limiting mechanism includes two limiting rings 12 , and the two limiting rings 12 are respectively arranged at two ends of the screw rod 6 .

[0035] In this embodiment, the screw rod 6 rotates in opposite directions during the rise and fall of the nut 7, and the screw rod 6 switches directions when the nut 7 abuts against the two limit rings 12. The forward and reverse drive member 5 can be a motor that can realize forward and reverse rotation.

The telescopic direction of the spring 14 is the same as the extension direction of the first connecting rod 8. One end of the spring 14 is connected to the first connecting rod 8, and the other end is connected to the push rod 15; the push rod 15 extends out of the first connecting rod 8 at one end away from the spring 14 and is connected to the annular scraper 13.

[0040] In this embodiment, the push rod 15 pushes the annular scraper 13 under the elastic force of the spring 14 to always be in contact with the inner wall of the mixing tank 2, which is convenient for improving the scraping effect when the scraper rises or falls.

[0042] In this embodiment, different amounts of liquid can be loaded into each feed cylinder 16 to measure the various liquids injected into the mixing tank 2, so as to control the proportion of the various liquids. The second valve 17 is used to control the on-off of the feed cylinder 16. When the liquid reaches the required amount, the second valve 17 can be opened, and the liquid will flow into the mixing tank 2.
