[0002] A seed coating machine is a machine that coats the surface of selected seeds with a coating agent to make them pelletized. There are rotary drum type, floating type and comprehensive type. It consists of a coating tank, batching, metering, spraying, air supply, power and transmission devices. The seeds and the coating agent are repeatedly rubbed and extruded against each other in the coating tank, so that a coating layer with a certain strength is formed on the surface of the seeds. The coated seeds are of the same size and shape, which is beneficial to mechanical sowing, improves sowing accuracy, reduces the amount of seeds used and the workload of thinning seedlings.

[0003] When most of the existing seed coating machines are in use, the staff prepare the coating agent and then put it into the coating machine from the surface of the coating machine. In this process, the coating agent will first contact the seeds on the upper surface inside the coating machine, which is likely to cause uneven mixing of the inner seeds and affect the coating quality. In view of this, we propose a coating device for seed breeding to solve the above problems. Content of the Utility Model

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 and Figure 2 , a coating device for seed breeding, including a cylinder body 1 and a bottom cover 2. A fixed plate 3 is fixedly installed on the surface of the cylinder body 1, and a rotating rod 4 extending into the cylinder body 1 is rotatably installed on the surface of the fixed plate 3.

[0025] Among them, a stirring assembly is provided on the surface of the rotating rod 4, and the stirring assembly is used for stirring seeds and coating agents.

[0026] A driving assembly for driving the rotation of the rotating rod 4 is provided on the surface of the fixed plate 3, and the driving assembly is used for driving the rotation of the stirring assembly.

[0027] An adding assembly for adding coating agents is further provided on the surface of the cylinder body 1, and the adding assembly is used for adding coating agents required for seed coating.

[0028] Please refer to Figure 2 , Figure 3 and Figure 5, The adding component includes a first threaded pipe 6 fixedly installed on the inner wall of the cylinder body 1. A second threaded pipe 5 is also fixedly installed on the surface of the rotating rod 4. A plurality of nozzles 7 are fixedly installed on the surfaces of the first threaded pipe 6 and the second threaded pipe 5. A feed port 11 is further opened at the top end of the rotating rod 4. The top end of the second threaded pipe 5 is communicated with the feed port 11. A medicine adding cylinder 8 is fixedly installed on the top of the cylinder body 1. A three-way joint 9 is fixedly installed at one end of the medicine adding cylinder 8. A connecting pipe 10 is fixedly installed at one end of the three-way joint 9. The other end of the connecting pipe 10 is communicated with the feed port 11. The top end of the first threaded pipe 6 is connected to the other end of the three-way joint 9.

[0029] Among them, the coating agent is put into the medicine adding cylinder 8, and then the coating agent flows into the interiors of the first threaded pipe 6 and the second threaded pipe 5 respectively through the three-way joint 9, and finally flows out through the nozzles 7. The threaded first threaded pipe 6 and second threaded pipe 5 enable the coating agent to be distributed more evenly inside the cylinder body 1, so that the seeds inside the cylinder body 1 can contact the coating agent more fully, greatly improving the mixing efficiency of the coating agent and the seeds, and thus improving the coating quality of the seeds.

[0030] In this embodiment, the bottom ends of the first threaded pipe 6 and the second threaded pipe 5 are both sealed. A flow limiting block 23 is fixedly installed on the inner wall of the lower port of the three-way joint 9.

[0031] It should be noted that the flow limiting block 23 is used to reduce the area of the lower port of the three-way joint 9, so as to ensure that the coating agent can flow into the interiors of the first threaded pipe 6 and the second threaded pipe 5 simultaneously.

[0032] Please refer to Figure 1 , In this embodiment, a cylinder cover 17 is further installed on the top of the medicine adding cylinder 8. Scale lines 16 are marked on the surface of the medicine adding cylinder 8.

[0033] Among them, by marking the scale lines 16 on the surface of the medicine adding cylinder 8, it is convenient for the staff to prepare the amount of the coating agent according to the amount of the seeds, which can reduce the situation that the coating quality is affected by too little coating agent or waste is caused by too much coating agent, and improves the practicability of the device.

[0034] Please refer to Figure 4 , In this embodiment, the stirring component includes a plurality of stirring rods 12 fixedly installed on the surface of the rotating rod 4. The stirring rods 12 are distributed alternately with the second threaded pipe 5. The driving component includes a toothed ring 13 fixedly installed on the surface of the rotating rod 4. A motor 14 is also fixedly installed on the surface of the fixed plate 3. A gear 15 meshing with the toothed ring 13 is fixedly installed at the output end of the motor 14.

[0035] Among them, starting the motor 14 drives the gear 15 to rotate, so that the rotating rod 4 rotates through the toothed ring 13. When the rotating rod 4 rotates, it will stir the seeds through the stirring rods 12, thereby accelerating the mixing efficiency of the coating agent and the seeds.

[0036] Please refer to Figure 2 In this embodiment, the lower surface of the inner wall of the cylinder body 1 is arranged in a hopper shape. Inside the bottom cover 2, there is also a plugging component for plugging the bottom opening of the cylinder body 1. The plugging component includes a cylinder 18 fixedly installed on the inner bottom wall of the bottom cover 2. The output end of the cylinder 18 is fixedly installed with a plugging plate 19. At the top of the plugging plate 19, there is a conical blanking block 20 fixedly installed. The blanking block 20 is located inside the bottom port of the cylinder body 1.

[0037] Among them, starting the cylinder 18 to drive the plugging plate 19 to move can adjust the opening and closing state of the bottom end of the cylinder body 1, thereby facilitating the discharge of the coated seeds.

[0038] In addition, the conical blanking block 20 enables the seeds inside the cylinder body 1 to flow into the inside of the bottom cover 2 more quickly.

[0039] In this embodiment, a cover door 21 is also hinged on the surface of the bottom cover 2, and an observation glass 22 is embedded on the surface of the cover door 21.

[0040] Finally, after the seed coating collection is completed, opening the cover door 21 can take out the coated seeds. Through the provided observation glass 22, it is convenient for the staff to observe the amount of seeds collected inside the bottom cover 2.

[0041] When this embodiment is in use, the seeds to be coated are placed inside the cylinder body 1. Start the motor 14 to drive the gear 15 to rotate, and then drive the rotating rod 4 to rotate through the toothed ring 13. When the rotating rod 4 rotates, it will stir the seeds through the stirring rod 12. At the same time, according to the amount of seeds, the prepared coating agent is placed inside the medicine feeding cylinder 8. The coating agent will flow into the inside of the first threaded pipe 6 and the second threaded pipe 5 respectively, and finally flow out through the nozzle 7. The threaded first threaded pipe 6 and the second threaded pipe 5 enable the coating agent to be distributed more evenly inside the cylinder body 1, so that the seeds inside the cylinder body 1 can come into contact with the coating agent more fully, greatly improving the mixing efficiency of the coating agent and the seeds, and thus improving the coating quality of the seeds.

[0042] All the electrical components mentioned in the text are electrically connected to the main controller and the power supply.
