[0002] Powder formulations are dry powder preparations made from pesticide technicals, fillers, and adjuvants through mixing, pulverizing, and remixing processes. They belong to the basic form of solid pesticide formulations, and the formulations require a stirring device for mixing during production.

[0003] Chinese patent application publication number CN222135521U discloses a plastic powder raw material mixing device. This utility model can automatically discharge the mixed raw materials inside the mixing box, reducing the labor intensity of workers and making the discharge convenient. At the same time, the automatic discharge of multiple times can avoid the accumulation of plastic powder raw materials during mixing and avoid insufficient mixing.

[0004] Although the above-mentioned patented solution can automatically feed materials, the mixing device in the above-mentioned patent only uses the rotating rod and the mixing rod to move the raw materials inside in one direction as a whole. The raw materials poured in at the same time are prone to accumulating into clumps, resulting in slow mixing efficiency. Moreover, the mixed raw materials are prone to clogging the discharge port, affecting the discharge effect.

[0005] Therefore, a mixing and stirring device for powdered pharmaceutical raw materials is proposed here. Utility Model Content

[0006] This invention proposes a powder raw material mixing and stirring device, which can move up and down while the first stirring frame and the second stirring frame rotate in opposite directions, thereby improving the raw material mixing efficiency. At the same time, the guide screw rod is used to prevent the raw material from clogging the inside of the discharge port.

[0007] This utility model is achieved through the following technical solution: a powder raw material mixing and stirring device, including a processing shell, a connecting shell above the processing shell, and a stirring assembly for stirring the raw materials between the processing shell and the connecting shell. The stirring assembly includes a transmission sleeve sleeved on the top surface of the processing shell, a first stirring frame fixedly sleeved at the bottom end of the transmission sleeve, a rotating rod rotatably sleeved inside the transmission sleeve, a second stirring frame fixedly sleeved at the bottom end of the rotating rod, and a guide threaded rod fixed on the bottom surface of the rotating rod.

[0008] Furthermore, the stirring assembly also includes a first motor fixed to the inner wall of the connecting shell, the output end of the first motor fixed to the top of the rotating rod, an upper transmission gear fixedly sleeved around the outer periphery of the rotating rod, a first transmission gear meshing inside the upper transmission gear, and a first limiting block fixed to one side of the connecting shell rotatably sleeved on the rotating shaft at the bottom of the first transmission gear.

[0009] Furthermore, a lower transmission gear is fixedly sleeved on the top end of the transmission sleeve, and a second transmission gear meshes inside the lower transmission gear. The second transmission gear meshes with one side of the first transmission gear, and a second limiting block fixed on one side of the connecting shell is rotatably sleeved on the top shaft of the second transmission gear.

The shaft at the top of the second transmission gear 381 is rotatably sleeved with a second limiting block 382 fixed on one side of the connecting shell 2.

[0031] In the above scheme, the first motor 36 is started to drive the rotating rod 33 to rotate. The rotating rod 33 drives the second stirring frame 34 and the guide thread rod 35 to rotate. The upper transmission gear 37 and the first transmission gear 371 drive the second transmission gear 381 to rotate. Through the cooperation between the second transmission gear 381 and the lower transmission gear 38, the transmission sleeve 31 is driven to rotate outside the rotating rod 33. The transmission sleeve 31 rotates in the opposite direction to the rotating rod 33. The transmission sleeve 31 drives the first stirring frame 32 to rotate.
