[0019] like Figure 4 and Figure 5 As shown, an installation groove is formed between the outer wall and the inner wall of one side of the device body 1. An internal gear 4, a first spur gear 5 and a second spur gear 6 are rotatably connected on the inner wall of the installation groove. A connecting shaft is fixedly connected between the axis of the first spur gear 5 and the axis of the rotating block. The first spur gear 5 and the second spur gear 6 are meshed. The second spur gear 6 and the internal gear 4 are meshed. A connecting ring is fixedly connected between one side of the internal gear 4 and one side of the rotating ring 301. Specifically, the connecting shaft is rotatably connected to the rotating cavity opened on one side of the mounting groove via a sealed bearing, and the connecting ring is rotatably connected to the groove opening of the mounting groove via a seal. The seal is a prior art structure and means, and its sealing method and structure can refer to the sealing method between the motor and water pump bearings and the outdoor unit. High pressure sealing is achieved through a mechanical seal with a dynamic ring and a stationary ring. Since the sealed bearing, mechanical seal and seal are all prior art structures and equipment, their specific forms, usage methods and connection methods are all prior art means, and this application will not elaborate on them in detail.

[0020] like Figure 1 - Figure 3 As shown, the upper part of the device body 1 is fixedly connected to the feed pipe 8, the bottom of the device body 1 is fixedly connected to the discharge pipe 9, and a diversion output pipe 10 and a pressure pump 11 are installed. The diversion output pipe 10 is fixedly connected to the end of the discharge pipe 9 through the pressure pump 11, and several spray nozzles 12 are provided at the bottom of the diversion output pipe 10. Specifically, a diversion valve is installed between the spray nozzle 12 and the diversion output pipe 10.

[0021] like Figure 1 - Figure 3 As shown, a conveying groove 13 is formed on the bottom wall inside the device body 1. An auger rod 14 is rotatably connected to the inner wall of the conveying groove 13. An opening is provided at the bottom of the conveying groove 13 to be connected to the top opening of the discharge pipe 9.

[0025] Working principle: The material is fed into the device body 1 through the feed pipe 8, and then stirred by the central stirring mechanism 2 and the peripheral stirring mechanism 3. When it is necessary to spray the material, the material enters the diversion output pipe 10 through the discharge pipe 9 and is pressurized by the pressure pump 11, so that it is sprayed out from each spray nozzle 12. The corresponding servo motor 7 drives the first spur gear 5 to rotate forward, which in turn drives the stirring rod 202 to rotate forward. At the same time, the first spur gear 5 drives the inner gear 4 to rotate in reverse using the second spur gear 6, which in turn drives the rotating block to rotate in reverse. Thus, the material inside the device body 1 is stirred in the inner and outer layers by the relative rotation of the central stirring mechanism 2 and the outer stirring mechanism 3. The auger rod 14 is driven to rotate by the corresponding servo motor 7. Due to gravity and the agitation of the surrounding stirring mechanism 3, the material will fill the cavity of the conveying trough 13. The auger rod 14 is used to conveniently transport the material from each area to the outlet of the discharge pipe 9 and wait for discharge.
