The stirring assembly includes a stirring rod 8 rotatably connected to the inside of the stirring tank 7, and the stirring rod 8 is equipped with a first stirring part for horizontal stirring and a second stirring part for vertical stirring. A feeding tank 15 is installed above the first frame 1, and the feeding tank 15 is equipped with a dragon blade 16. A first pipe 20 is connected between the stirring tank 7 and the feeding tank 15. A first motor 14 for driving the stirring rod 8 and the dragon blade 16 to rotate in the corresponding tank is installed on the first frame 1. In the above structure, in order to ensure that the materials can be better mixed, a stirring component is designed to quickly mix the materials inside the stirring tank 7, and during the mixing process, it is only necessary to control the start and stop of the first motor 14, and the first motor 14 drives the stirring component to rotate in the stirring tank 7 to complete the rapid mixing of the drilling fluid and the additive; at the same time, the first motor 14 drives the dragon blade 16 to rotate in the feed tank 15 to realize the additive addition work, and the two are carried out simultaneously; wherein, during the rotation process, the dragon blade 16 pushes the additive in the feed tank 15 to one end of the first pipe 20, and flows into the stirring tank 7 through the first pipe 20, thereby satisfying the stirring while completing the additive addition, and the operation is convenient and efficient.

[0022] For the above-mentioned first motor 14 that can simultaneously drive the stirring rod 8 and the dragon blade 16 to rotate, the following linkage structure is implemented: that is, a first worm 13 is connected to the rotating shaft of the first motor 14 through a coupling, and the other end of the first worm 13 is connected to the dragon blade 16. A first worm wheel 12 engaged with the first worm 13 is installed on the top of the stirring rod 8. The rotating shaft of the first motor 14 is connected to the worm through a coupling, and the worm and the worm wheel are engaged. The worm drives the horizontally connected dragon blade 16 to rotate in the feed tank 15, and at the same time, the worm drives the worm wheel engaged with it to rotate with it, and the worm wheel is installed above the stirring rod 8, thereby driving the stirring part to stir the mixture in the stirring tank 7.

[0023] The above-mentioned first stirring part includes a stirring frame 10 and a first stirring branch plate 11 installed on the stirring frame 10.
