Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.
[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] To facilitate mixing, combine with the attached Figure 1 and attached Figure 3 A device for mixing and dispensing fish disease medication includes a barrel 1, a concave connecting plate 2 on one side of the barrel 1, and an injection port 3 at the top of the barrel 1. It also includes a stirring assembly. The bottom of the barrel 1 is an inverted conical structure. The stirring assembly is disposed inside the barrel 1 for mixing the fish medication. The stirring assembly includes a first motor 4, a stirring rod 5, and stirring blades 6. The first motor 4 is located at the top of the barrel 1. The stirring rod 5 is rotatably mounted inside the top of the barrel 1. Multiple stirring blades 6 are evenly distributed on both sides of the stirring rod 5, with the size of the lower stirring blades 6 decreasing sequentially. The first motor 4 drives the stirring rod 5 and stirring blades 6 to rotate continuously, thereby continuously stirring the fish medication inside the barrel 1 and quickly achieving uniform mixing.
[0025] To further improve delivery efficiency and save time and effort, in conjunction with the attached... Figure 2 and attached Figure 4The dispensing component includes a feeding pipe 7 at the bottom of the barrel 1, a control valve 10 on the feeding pipe 7, a rotatably connected conveying pipe 8 at the bottom of the feeding pipe 7, and a sprinkling pipe 9 at the bottom of the conveying pipe 8. The dispensing component directly drives the sprinkling pipe 9, dispensing the fish medicine through the continuous oscillation of the sprinkling pipe 9. The dispensing component includes a second motor 11, a first gear 12, and a second gear 13. The second motor 11 is located at the bottom of the concave connecting plate 2, the first gear 12 is located at the output end of the second motor 11, and the second gear 13 is located on the conveying pipe 8 and meshes with the first gear 12. When the second motor 11 is started, it drives the first gear 12 to rotate continuously, and the second gear 13, which meshes with the first gear 12, rotates accordingly, thereby driving the sprinkling pipe 9 to rotate. As the second motor 11 continuously rotates forward and backward, the sprinkling pipe 9 continuously oscillates in an arc, automatically sprinkling the fish medicine in the barrel 1, saving time and effort and achieving high dispensing efficiency.
[0026] To avoid fish medicine residue remaining on the inner wall of tank 1, combined with the attached... Figure 1 and attached Figure 2 The top of the barrel 1 is equipped with a water tank 14, and the top of the water tank 14 is equipped with a liquid pump 15 connected to the water tank 14. The top of the barrel 1 is equipped with a circular spray pipe 16 connected to the liquid pump 15. The top of the barrel 1 has multiple evenly distributed nozzles 17 that communicate with the spray pipe 16. The liquid pump 15 directly draws water from the water tank 14 and delivers it directly to the multiple nozzles 17 on the spray pipe 16. The multiple nozzles 17 can be used to rinse the fish medicine residue on the inner wall of the barrel 1, avoiding waste caused by residue.
[0027] In specific implementation of this utility model:
[0028] First, pour various fish medicines and water directly into the barrel 1 through the inlet 3. Then, cover the inlet 3 with a sealing cap and start the first motor 4. The first motor 4 drives the stirring rod 5 and stirring blade 6 to rotate continuously, which can continuously stir the fish medicine in the barrel 1 and quickly mix it evenly.
[0029] Next, the control valve 10 is opened, and the mixed fish medicine enters the feed pipe 8 and the spray pipe 9 through the feed pipe 7. At the same time, the second motor 11 is started. The second motor 11 drives the first gear 12 to rotate continuously, and the second gear 13, which meshes with the first gear 12, rotates accordingly, thereby driving the spray pipe 9 to rotate. As the second motor 11 rotates continuously in both directions, the spray pipe 9 continuously swings in an arc, automatically spraying the fish medicine in the barrel 1, saving time and effort and achieving high drug delivery efficiency.
[0030] After the fish medicine is applied, the liquid pump 15 is started. The liquid pump 15 directly draws water from the water tank 14 and sends it directly to multiple nozzles 17 on the spray pipe 16. The multiple nozzles 17 can be used to rinse the fish medicine residue on the inner wall of the barrel 1, avoiding waste caused by residue, and allowing the rinsing liquid to be directly sprayed out.
