Description

Technical Field

[0001] This utility model relates to the technical field of corn seed coating machines, and in particular to a drum-type corn seed coating machine. Background Technology

[0002] Seed coating is a technique that uses an adhesive (in liquid form) to coat the surface of seeds with powdered fertilizers, pesticides, etc. Corn seeds can also be coated. Current technology generally uses seed coating machines. These machines typically include a tiltable disc and a lifting agitator that moves in and out of the disc. They also include nozzles. During operation, the corn seeds to be coated are placed into the disc, the agitator stirs the seeds, then the powder (fertilizer, pesticide, etc.) is added, and the adhesive is sprayed in a mist through the nozzles. This mixes the powder and adhesive, causing them to adhere to the seed surface. The agitator then retracts from the disc, the nozzles stop operating, and finally, the disc is tilted to remove the coated seeds. However, in actual operation, a large amount of adhesive is often needed to achieve the desired coating thickness. Excess adhesive cannot be removed promptly, requiring the addition of more powder, making it difficult to control the coating thickness. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a roller-type corn seed coating machine, which solves the problem that excessive adhesive is difficult to remove in time, making it difficult to control the coating thickness.

[0004] According to an embodiment, a roller-type corn seed coating machine is provided, comprising a fixed outer shell, a horizontally arranged outer shell containing a roller, and a first rotating cylinder and a second rotating cylinder extending outwards from the outer shell at both ends of the roller, respectively. A driver for rotating the first rotating cylinder is also provided on the outer shell. An installation tube is provided inside the roller, with one end of the installation tube passing through the second rotating cylinder and extending outwards from the outer shell. Multiple nozzles are fixedly connected to the installation tube. A first through-frame and a removable cover for the first through-frame are provided on the roller wall. Several through holes are provided on the roller. A second through-frame is provided at the bottom of the outer shell, and the cover can enter and exit the second through-frame. This solution uses a roller as the coating site. The through holes on the roller allow excess adhesive to flow outwards to the outer shell and then be discharged through the second through-frame, thereby better controlling the coating thickness and solving the problem in the prior art where excessive adhesive is difficult to discharge in time, leading to difficulty in controlling the coating thickness.

[0005] Furthermore, the cap and the roller are detachably connected via a connector.

[0006] Furthermore, an outer frame is also fixedly connected to the outer casing, surrounding the second through frame.

[0007] Furthermore, a support frame is fixedly connected to the outer casing, and the mounting tube passes through the support frame.

[0008] Furthermore, a first fixing ring and a second fixing ring are fixedly connected to both ends of the outer shell, and the first rotating cylinder and the second rotating cylinder rotate through the first fixing ring and the second fixing ring, respectively.

[0009] Furthermore, the driver includes a drive motor fixed to the housing and a reducer connected to the drive motor. The reducer has an output end and a first connecting wheel is fixedly connected to the output end. A second connecting wheel located outside the housing is fixedly connected to the outer wall of the first rotating cylinder. A drive belt is wound between the first connecting wheel and the second connecting wheel.

[0010] Furthermore, multiple arc-shaped plates are fixedly connected to the inner wall of the roller.

[0011] Furthermore, the mounting tube includes a mounting section located on the upper part of the outer casing, and an extension section fixed to the mounting section, the extension section being bent downward and extending laterally through the second rotating cylinder to the outer casing.

[0012] Furthermore, a support leg is fixedly connected to the bottom of the outer casing.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Using a roller as the coating site, the through holes on the roller allow excess adhesive to be discharged outwards into the outer shell, and then discharged through the second through frame. This allows for better control of the coating thickness and solves the problem in the prior art where excess adhesive is difficult to discharge in time, making coating thickness control difficult.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , 2As shown, this embodiment provides a roller-type corn seed coating machine, which includes a horizontally arranged outer shell 1, which is a cylindrical structure. Perforations are provided at both ends of the outer shell 1. A roller 2 is also arranged horizontally inside the outer shell 1, and a first rotating cylinder 3 and a second rotating cylinder 4, which respectively rotatably extend outside the outer shell 1, are fixedly connected to both ends of the roller 2. That is, the first rotating cylinder 3 and the second rotating cylinder 4 rotatably pass through the two perforations, thus allowing the roller 2 to rotatably reside inside the outer shell 1. A drive motor 5 and a reducer 6 connected to the drive motor 5 are also fixedly installed on the outer shell 1. The reducer 6 has an output end, and a first connecting wheel 7 is fixedly connected to the output end. A second connecting wheel 8 is fixedly connected around the end of the first rotating cylinder 3 located outside the outer shell 1. A drive belt 9 is wound between the first connecting wheel 7 and the second connecting wheel 8. Thus, the operation of the drive motor 5 drives the roller 2 to rotate within the outer shell 1. A first through frame is also provided on the roller 2, located on its cylindrical wall. The frame is covered and opened by a cover 10 detachably connected to the roller 2. Specifically, the second rotating cylinder 4 also serves to connect the inside and outside of the roller 2, so that corn seeds and powder can be introduced into the roller 2 from the second rotating cylinder 4. A second through frame is also provided at the bottom of the outer shell 1, and the cover 10 can enter and exit the outer shell 1 from the second through frame. After the coating is completed, the cover 10 can be opened and the coated seeds can be poured out (the cover 10 also has a plate surface flush with the inner wall of the roller 2 to avoid material accumulation in the first through frame). In particular, several through holes are provided on the roller 2. These through holes allow excess adhesive to be thrown out into the outer shell 1 during the coating process and then discharged through the second through frame. This ensures that the amount of adhesive is appropriate during the coating process, avoiding the need to add more powder due to excess adhesive, which would lead to a larger final thickness. Therefore, the coating thickness can be better controlled, solving the problem in the prior art where excessive adhesive is difficult to discharge in time, making it difficult to control the coating thickness.In a further embodiment, an installation pipe is provided inside the roller 2. Specifically, the installation pipe includes an installation section 11 located at the upper part of the outer casing 1. Multiple nozzles 12 are fixedly installed on the installation section 11, with their nozzles facing downwards. The installation pipe also includes an extension section 13 fixedly connected to the installation section 11. The extension section 13 bends downwards and laterally passes through the second rotating cylinder 4 to the outside of the outer casing 1. A support frame 14 is also fixedly connected to the outer casing 1 for the extension section 13 to pass through. This allows the installation pipe to be fixed relative to the outer casing 1 inside the roller 2. During operation, adhesive is introduced through the extension section 13 and sprayed into the roller 2 in a mist form through the nozzles 12. Simultaneously, the drive motor 5 rotates the roller 2. The sample powder and seeds are turned over and come into contact with the sprayed adhesive, causing the powder to coat the seed surface. After a period of time, coating is achieved. Throughout the process, the adhesive can efficiently contact the powder, resulting in more efficient coating and preventing excess material (excess material would be thrown into the outer shell 1 by centrifugal force). In particular, the through-holes are very small in diameter, preventing the powder from passing directly through them, especially after the adhesive is sprayed, as the powder adheres more to the seed surface and will not pass through the through-holes, thus preventing loss. After operation, cleaning water can be introduced through the installation pipe to clean the inside of the drum 2. During cleaning, wastewater can be discharged through the first through-frame to the outer shell 1, and then through the second through-frame to the outside of the outer shell 1.

[0017] like Figure 1 , 2 As shown, the two ends of the outer shell 1 are respectively fixedly connected to the first fixing ring 15 and the second fixing ring 16 through perforations. The first rotating cylinder 3 and the second rotating cylinder 4 rotate through the first fixing ring 15 and the second fixing ring 16 respectively. This enables the outer shell 1 to provide more stable rotational support for the first rotating cylinder 3 and the second rotating cylinder 4, thereby improving the overall stability of the device operation.

[0018] like Figure 1-3As shown, in a further embodiment, the cap 10 and the roller 2 are detachably connected via a connector 17, which can be a screw. This detachable design facilitates assembly and disassembly. In an even further embodiment, an outer frame 18 is fixedly connected to the outer casing 1, surrounding the second through frame. The outer frame 18 also allows the cap 10 to enter and exit. Simultaneously, the outer frame 18 prevents excess adhesive from spreading outwards along the bottom surface of the outer casing 1. A container placed below the outer frame 18 can catch the adhesive for subsequent processing, such as adding it to the next cycle of operation (in actual operation, adhesive, powder, and...). (There is a suitable ratio range between the seeds, and less adhesive is thrown out, so as not to cause a lot of adhesive waste.) Furthermore, the bottom of the outer shell 1 is fixedly connected to the support leg 20, so as to raise the outer shell 1, thereby facilitating the opening and closing of the cap 10 from below the outer shell 1. In an even more advanced solution, multiple arc-shaped plates 19 are fixedly connected to the inner wall of the roller 2, which can increase the degree of material turning during operation, thereby further improving the coating efficiency (the rotation speed is low during operation, although the degree of turning is increased, it will not cause the coated seeds to break due to impact).

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
