Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Figures 1-3 The diagram shown is a complete structural schematic of a corn seed coating and drying integrated device according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of a corn seed coating and drying integrated device includes a liquid tank 100 containing coating liquid, a wetting port 110 centrally located at the top of the liquid tank 100, a cover 700 at the top of the liquid tank 100, and a mounting bracket 200 that moves up and down driven by a drive device located above the inside of the cover 700. A perforated rotating cylinder 300 is horizontally and movably mounted on the inner side and lower part of the mounting bracket 200, and is driven by a drive device on one side of the mounting bracket 200 to rotate longitudinally. The hollow rotating cylinder 300 is located directly above the immersion port 110. Inside the hollow rotating cylinder 300, an air jet pipe 400 is installed at the axis, and several diffuser nozzles 410 are distributed at the bottom of the air jet pipe 400. The upper end of the housing 700 is provided with a hot air output device 600 for inputting hot airflow into the air jet pipe 400. The air jet pipe 400 and the hollow rotating cylinder 300 are coaxially rotated and installed, and one end of the air jet pipe 400 extends to the outside of the hollow rotating cylinder 300 and is fixed on the mounting bracket 200.

[0022] The front of the housing 700 is equipped with an operating port and a matching door 710. The side of the perforated rotating drum 300 is equipped with a material inlet and a matching conveying gate 330. It is understood that by opening the door 710 and the conveying gate 330, corn seeds can be easily fed into the perforated rotating drum 300, and vice versa. It should be noted that when removing seeds, the conveying gate 330 should be rotated downwards to unload the material, and vice versa for loading. The perforated rotating drum 300 has a first rotating shaft 310 at one end and a second rotating shaft 320 at the other end. Both the first and second rotating shafts 310 and 320 are rotatably mounted on the mounting bracket 200 via bearings. One end of the air jet pipe 400 is movably inserted through the inner and outer ends of the first rotating shaft 310 via a sealing shaft. A positioning bracket 210, which is fixedly connected to the outer end of the air jet pipe 400, is also provided on the outer side of the mounting bracket 200. With the cooperation of the positioning frame 210 and bearings, the jet nozzle 400 will not rotate with the hollow rotating drum 300, ensuring that the scattering nozzle 410 always faces the corn seeds piled below the rotating drum. A lifting cylinder 500 is installed at the upper part of the inner casing 700 to move the mounting bracket 200 up and down. A servo motor 510 is installed on one side of the mounting bracket 200 to drive the second rotating shaft 320 to rotate axially. The hot air output device 600 includes an electric heating wire heater 610 installed at the upper part of the casing 700, a fan 620 installed on one side of the electric heating wire heater 610, an air guide duct 630 with one end connected to the output end of the fan 620 and the other end connected to the output end of the electric heating wire heater 610, and a flexible air supply hose 640 with one end connected to the output end of the electric heating wire heater 610 and the other end connected to the outer end of the jet nozzle 400. Specifically, in this embodiment, corn seeds are introduced into the perforated rotating drum 300, and then the lower part of the hanging frame and the perforated rotating drum 300 is lowered into the immersion port 110 by the lifting electric cylinder 500 and immersed in the coating liquid in the liquid tank 100. Then, the perforated rotating drum 300 is rotated by the servo motor 510, so that the seeds in the drum continuously turn over and make full contact with the coating liquid. After completion, the perforated rotating drum 300 is lifted and then dried. During this time, the perforated rotating drum 300 continues to rotate, and the hot air output device 600 inputs a large amount of hot air into the jet pipe 400. The jet pipe 400 uses the bottom scattering nozzle 410 to perform close-range drying and blowing on the corn seeds in the lower part of the drum that are constantly turning over. The dripping coating liquid falls directly into the liquid tank 100, thereby realizing the automatic integrated continuous processing of corn seed coating and drying, saving a lot of time and improving seed production efficiency.

[0023] Furthermore, limiting guide strips 120 are provided on the top of the liquid tank 100 and on both sides of the soaking port 110, and a drain valve 130 is provided on one side of the bottom of the liquid tank 100. It can be understood that when unloading the coated and dried seeds, the box door 710 can be opened directly, and the receiving tray / box can be smoothly placed into the upper part of the liquid tank 100 along the inner side of the limiting guide strips 120 and covered by the soaking port 110. In this way, after opening the conveying door 330, the seeds in the hollow rotating drum 300 will automatically flow into the receiving tray, thereby completing the receiving work, which is simple and easy to operate.

[0024] Furthermore, a controller 800 is also installed on the outside of the enclosure 700. In actual use, the operator can use the controller 800 to control and set the various operating units of the coating and drying integrated device, making the device more convenient to use.

[0025] In summary, the integrated corn seed coating and drying device of this embodiment operates by introducing corn seeds into a perforated rotating drum 300. Then, a lifting cylinder 500 lowers the hanger and the lower half of the perforated rotating drum 300 to the inside of the wetting port 110, immersing them in the coating liquid in the liquid tank 100. A servo motor 510 then drives the perforated rotating drum 300 to rotate, causing the seeds inside to continuously tumble and fully contact the coating liquid. After completion, the perforated rotating drum 300 is lifted for drying. During this process, the perforated rotating drum 300 continues to rotate, while a hot air output device 600 inputs a large amount of hot air into the jet nozzle 400. The jet nozzle 400, through its bottom scattering nozzle 410, performs close-range drying and blowing on the continuously tumbling corn seeds in the lower part of the drum. The dripping coating liquid falls directly into the liquid tank 100, thus achieving automatic integrated continuous processing of corn seed coating and drying, saving a significant amount of time.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
