[0032] When in use, urea and liquid are first poured into the first feed pipe 2 and the second feed pipe 3 respectively, so that the urea and liquid can enter the barrel body 1. After the urea and liquid enter the barrel body 1, the urea and liquid will first accumulate on the top of the partition 7, and then fall to the inner bottom of the barrel body 1 through the through hole on the partition 7. At this time, the motor 4 is driven to drive the shaft 5 to rotate, and the shaft 5 can drive the stirring rod 6 to rotate. At this time, the urea and liquid on the top surface of the partition 7 can be stirred, and then the two can be preliminarily mixed, thereby accelerating the mixing efficiency of urea and liquid and ensuring the mixing quality.

[0033] Reference Figure 1-Figure 2 , the first feed pipe 2 and the middle of the second feed pipe 3 are both provided with a first valve 8. A discharge pipe 9 is fixedly connected to one side of the bottom surface of the barrel body 1, a second valve 10 is provided in the middle of the discharge pipe 9, a support leg 11 is fixedly connected to the outer side of the middle of the bottom surface of the barrel body 1, and a heating pipe is provided inside the barrel body 1. The opening and closing of the first feed pipe 2 and the second feed pipe 3 can be controlled by the first valve 8, and the urea and liquid after mixing can be discharged from the discharge pipe 9 by opening the second valve 10, and the barrel body 1 can be heated by driving the heating pipe, thereby further accelerating the mixing efficiency.

[0034] Reference Figure 2-Figure 4 The tumbling assembly includes an upper blade 12 and a lower blade 13, and the upper blade 12 and the lower blade 13 are fixedly connected to the middle upper part and the middle lower part of the rotating shaft 5 respectively.

A cross bar 14 is fixedly connected to the middle part of the rotating shaft 5, a primary vertical bar 15 is fixedly connected to the middle part of the cross bar 14, and a secondary vertical bar 16 is fixedly connected to the outer side of the cross bar 14. The upper blade 12 can be used to drive urea and liquid to move to the cross bar 14, and the lower blade 13 can be used to drive urea and liquid at the bottom of the barrel 1 to the cross bar 14. At this time, the urea and liquid in the middle of the barrel 1 can be broken up by the rotation of the cross bar 14, the primary vertical bar 15 and the secondary vertical bar 16, so that the collision between the urea and the liquid can be aggravated, thereby improving the mixing efficiency and mixing quality of the urea and liquid, thereby improving the efficiency of the operation.

[0035] Reference Figure 2-Figure 3 The bottom surface of the inner wall of the barrel body 1 is fixedly connected with a protrusion 17, and the rotating shaft 5 is rotatably connected to the middle of the protrusion 17. An arc surface 18 is arranged outside the middle of the protrusion 17. The arc surface 18 guides urea and liquid to flow to both sides of the bottom of the barrel body 1.

[0036] Working principle: When in use, first pour urea and liquid into the first feed pipe 2 and the second feed pipe 3 respectively, and then open the first valve 8, so that urea and liquid can enter the barrel body 1. After the urea and liquid enter the barrel body 1, the urea and liquid will first accumulate on the top of the partition 7, and then fall to the inner bottom of the barrel body 1 through the through hole on the partition 7. At this time, the motor 4 is driven to drive the shaft 5 to rotate, and the shaft 5 can drive the stirring rod 6 to rotate. At this time, the urea and liquid on the top surface of the partition 7 can be stirred, and then the two can be preliminarily mixed. After the urea and liquid fall from the through hole of the partition 7, the rotation of the shaft 5 can also drive the upper blade 12, the lower blade 13, the cross bar 14, the first-level vertical rod 15 and the second-level vertical rod 16 The upper paddle 12 can be used to drive the urea and liquid to move to the cross bar 14, and the lower paddle 13 can be used to drive the urea and liquid at the bottom of the barrel 1 to the cross bar 14. At this time, the urea and liquid in the middle of the barrel 1 can be broken up by the rotation of the cross bar 14, the first-level vertical bar 15 and the second-level vertical bar 16, thereby intensifying the collision between the urea and the liquid, thereby improving the mixing efficiency and mixing quality of the urea and liquid, thereby improving the efficiency of the operation, and in the mixing process, the barrel 1 can be heated by driving the heating tube, and then the urea and liquid can be heated, thereby further accelerating the mixing efficiency. When the mixing is completed, the second valve 10 is opened, and the urea and liquid after the mixing are discharged from the discharge pipe 9, thereby completing the mixing of the urea and the liquid.
