[0028] A support seat 4, the bottom end of which is fixedly mounted on the left side of the top of the mixing drum 1;

[0029] A rotating mechanism, which is arranged inside the supporting seat 4;

[0030] Among them, the rotating mechanism includes a pneumatic cylinder 5, which is fixedly installed inside the top of the support seat 4. The front end of the pneumatic cylinder 5 is fixedly connected with a sleeve rod 6, and the inner part of the sleeve rod 6 is movably sleeved with a connecting rod 7. A vertical plate 8 is fixedly installed on the right side of the connecting rod 7. The top of the vertical plate 8 is fixedly connected to the bottom of the horizontal plate 3. The left and right movement of the sleeve rod 6 will cause the horizontal plate 3 to rotate.

[0031] When the pneumatic cylinder 5 starts to run, the sleeve rod 6 will move forward horizontally, and the connecting rod 7 will drive the vertical plate 8 to move, so that the horizontal plate 3 will drive the round rod 10 to rotate under the limiting effect of the mounting plate 2, thereby achieving the purpose of rotating the horizontal plate 3 and improving the stirring efficiency of the device.

[0032] A transverse groove 19 is provided in the middle of the top of the mixing drum 1 , a driving motor 11 is fixedly installed in the middle of the top of the transverse plate 3 , and a rotating shaft 12 is fixedly sleeved on the other end of the output shaft of the driving motor 11 .

[0033] When the driving motor 11 starts to run, the rotating shaft 12 will rotate.

[0034] Among them, the bottom end of the rotating shaft 12 passes through the horizontal plate 3 and extends to the inside of the mixing drum 1. The outer surface of the rotating shaft 12 is movably connected to the inside of the horizontal groove 19. The outer surface of the rotating shaft 12 is fixedly sleeved with a fixed sleeve 13, and the outer surface of the fixed sleeve 13 is movably sleeved with a stirring blade 14.

[0035] When the rotating shaft 12 rotates, the fixing sleeve 13 and the stirring blade 14 are driven to rotate.

[0036] A feed pipe 15 is fixedly sleeved inside the front of the top of the mixing drum 1 , a discharge pipe 16 is fixedly sleeved inside the middle of the bottom of the mixing drum 1 , and a valve 17 is fixedly connected to the bottom end of the discharge pipe 16 .

[0037] The operator can add the sewage to be mixed into the mixing drum 1 through the feed pipe 15 , and after the mixing is completed, open the valve 17 , and the mixed sewage will be discharged from the device through the discharge pipe 16 .

[0038] The bottom of the mixing drum 1 is fixedly connected with support rods 18 . There are four support rods 18 , and the sizes of the four support rods 18 are the same.

[0039] Such a design makes the device more stable during operation.

[0040] The inner surface of the fixing sleeve 13 is fixedly connected with a spring 21 , the inner surface of the stirring blade 14 is provided with limiting grooves 9 located on the left and right sides of the fixing sleeve 13 , and the other end of the spring 21 is fixedly connected with a limiting block 20 .

[0041] Due to the design of the spring 21 , the limit block 20 has a good reset effect in subsequent movements.

[0042] The outer surface of the limiting block 20 is movably connected to the interior of the fixing sleeve 13 and the limiting groove 9 respectively, and the outer surface of the limiting block 20 is smooth.

[0043] When the stirring blade 14 moves to the position of the limiting block 20 , the limiting block 20 will enter the limiting groove 9 due to the elastic force of the spring 21 , thereby achieving the fixing effect on the stirring blade 14 .

[0044] The working principle and use process of this utility model:

[0045] First, the sewage and medicine to be mixed are added into the mixing drum 1 through the feed pipe 15, and then the drive motor 11 is started, so that the rotating shaft 12 drives the fixed sleeve 13 and the stirring blade 14 to rotate. At this time, the mixing operation will be carried out, and then the pneumatic cylinder 5 is started to make the sleeve rod 6 move forward horizontally, and the connecting rod 7 drives the vertical plate 8 and the horizontal plate 3 and the round rod 10 to rotate under the limiting action of the mounting plate 2, thereby driving the rotating shaft 12 and the stirring blade 14 to swing under the limiting action of the horizontal groove 19, thereby achieving the purpose of sufficient mixing and improving the mixing efficiency of the device.

[0046] When the stirring blade 14 is damaged during long-term use and needs to be replaced, the stirring blade 14 is pulled, so that the limit block 20 moves horizontally to the left under the limiting action of the limit groove 9 and the fixing sleeve 13, and the spring 21 is in a compressed state. When the limit block 20 is separated from the inside of the stirring blade 14, the fixing effect on the stirring blade 14 will be released, thereby achieving the purpose of facilitating the disassembly and assembly of the stirring blade 14 and reducing the labor intensity of the operator.
