Description

Technical Field

[0001] The utility model relates to the technical field of seed processing, and more specifically, to a coating device for seedling production. Background Technique

[0002] The coating device is an important equipment in modern pharmacy, which is used to coat a protective layer on the outer surface of materials. Usually, it is responsible for coating a film-forming material on the surface of materials to form a tightly adhered protective layer. The coating device is often used in combination with equipment such as extruders, spheronizers, granulators, and dryers to achieve multi-functional fluidized granulation and coating. During the process of seedling production, it is necessary to coat the surface of seedlings with liquid medicine through the coating device.

[0003] As disclosed in a Chinese patent: A seed coating device, application number: CN202223309424.5, includes a housing. A spraying component is arranged in the cavity of the housing. After the seeds overflow from the outer shell port of the conveyor, the seeds squeeze against the inner wall surface of the blocking part and fall. After being dispersed by the blocking part, the seeds fall in a waterfall shape onto the circumferential surface of the guiding part. Guided by the inclined circumferential surface of the guiding part, the seeds are dispersed towards the surroundings. The transfer pump transports the blended liquid medicine through a connecting pipe to the cavity of the spraying part, and the liquid medicine is sprayed onto the surface of the seeds sliding down from the circumferential surface of the guiding part through the spraying holes at the bottom of the spraying part to complete the coating. The seeds are spread out, and while sliding down, the seeds are wetted by the liquid medicine. The seed coating is more uniform, the coating effect is better and more stable, the number of seeds not wetted by the liquid medicine is reduced, and the germination rate of the seeds is improved.

[0004] However, in the above technical solution, when coating seedlings (seeds), it is necessary to guide the seedlings to disperse towards the surroundings through the inclined circumferential surface of the guiding part, and then spray and coat the seedlings through the spraying part. When the seedlings disperse towards the surroundings, a large number of seedlings will push against each other, making it difficult for some seedlings to turn over. Therefore, the spraying part can only spray and coat the surface of these seedlings facing the spraying part, and the other surfaces of these seedlings will not be sprayed, so they cannot be coated or the coating thickness is relatively thin, resulting in uneven coating on each surface of the seedlings. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a coating device for seedling production, which can effectively solve the problem in the background technique that when coating seedlings (seeds), it is necessary to guide the seedlings to disperse towards the surroundings through the inclined circumferential surface of the guiding part, and then spray and coat the seedlings through the spraying part. When the seedlings disperse towards the surroundings, a large number of seedlings will push against each other, making it difficult for some seedlings to turn over. Therefore, the spraying part can only spray and coat the surface of these seedlings facing the spraying part, and the other surfaces of these seedlings will not be sprayed, so they cannot be coated or the coating thickness is relatively thin, resulting in uneven coating on each surface of the seedlings.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0007] A coating device for seedling production, comprising a device main body, a conveyor and a spraying assembly are arranged on the device main body, a feed hopper is arranged on one side of the device main body, a vibrator is arranged on the conveyor, a guiding part is arranged on the vibrator, a plurality of filtering grooves are arranged on the guiding part, a groove is arranged on one side of the guiding part, a spring is fixedly arranged in the groove, a collecting hopper is fixedly arranged on the spring, and a plurality of conveying pipes are arranged on the collecting hopper.

[0008] Preferably, the guiding part is slidably connected with the collecting hopper, and the collecting hopper is fixedly connected with the conveyor.

[0009] Preferably, a slip ring is slidably arranged on the conveyor by the vibrator.

[0010] Preferably, two cams are arranged on one side below the slip ring, a rotating column is arranged on the cam, and a motor is arranged on the rotating column.

[0011] Preferably, the slip ring is slidably connected with the conveyor.

[0012] Preferably, the motor is fixedly installed on the conveyor.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] (1) Firstly, the present utility model enables the material to enter the device main body through the feed hopper, and then conveys the material in the device main body from bottom to top through the conveyor, transports the material to the guiding part, and simultaneously starts the motor and the spraying assembly to vibrate the guiding part. The material on the guiding part is continuously turned over by the vibrating guiding part, and the spraying assembly sprays the liquid medicine on the continuously turned-over material, so that the coating on each side of the material is more uniform. Then the excess liquid medicine will pass through the filtering grooves and fall into the collecting hopper, and the collecting hopper will convey the excess liquid medicine to the designated position through the conveying pipe, which is convenient for recycling the excess liquid medicine. It can not only make the coating on each side of the material more uniform, but also recycle the excess liquid medicine to save costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 3 shown, a coating device for seedling production includes a device main body 1, a conveyor 2 and a spraying assembly 3 are arranged on the device main body 1, a feed hopper 4 is arranged on one side of the device main body 1, a vibrator 5 is arranged on the conveyor 2, a guiding part 6 is arranged on the vibrator 5, a plurality of filtering tanks 7 are arranged on the guiding part 6, a groove 8 is arranged on one side of the guiding part 6, a spring 9 is fixedly arranged in the groove 8, a collecting hopper 10 is fixedly arranged on the spring 9, and a plurality of conveying pipes 11 are arranged on the collecting hopper 10.

[0022] As Figure 4 shown, in another embodiment of the present utility model, a slip ring 501 is slidably arranged on the conveyor 2 by the vibrator 5;

[0023] On one side below the slip ring 501, two cams 502 are arranged, a rotating column 503 is arranged on the cam 502, and a motor 504 is arranged on the rotating column 503. When it is necessary to vibrate the guiding part 6, first, the rotating column 503 is rotated by the motor 504, the rotating column 503 drives the cam 502 to rotate, so that the cam 502 rotates around the rotating column 503, and then the cam 502 periodically presses the slip ring 501, so that the slip ring 501 moves upward by a certain distance. When the cam 502 does not press the slip ring 501, the slip ring 501 falls under the action of gravity, so that the slip ring 501 makes a reciprocating motion, and then the guiding part 6 is driven to move by the slip ring 501, so that the guiding part 6 vibrates.

[0024] The working principle of the coating device for seedling production:

[0025] During use, first, the material enters the device main body 1 through the feed hopper 4, and then the conveyor 2 conveys the material in the device main body 1 from bottom to top and transports the material to the guiding part 6. At the same time, the motor 504 and the spraying assembly 3 are started. The rotating column 503 rotates through the motor 504, and the rotating column 503 drives the cam 502 to rotate, so that the cam 502 rotates around the rotating column 503. Then, the cam 502 periodically presses the slip ring 501, causing the slip ring 501 to move upward by a certain distance. When the cam 502 does not press the slip ring 501, the slip ring 501 falls under the action of gravity, so that the slip ring 501 makes a reciprocating motion. Then, the slip ring 501 is used to drive the guiding part 6 to move, so that the guiding part 6 vibrates. The material on the guiding part 6 is continuously turned over through the vibrating guiding part 6, and the spraying assembly 3 is used to spray the liquid medicine on the continuously turned-over material, so that the coating on each surface of the material is more uniform. Then, the excess liquid medicine will pass through the filter tank 7 and fall into the collection hopper 10. The collection hopper 10 then transports the excess liquid medicine to the designated position through the conveying pipe 11, which is convenient for recycling the excess liquid medicine. This not only makes the coating on each surface of the material more uniform, but also can recycle the excess liquid medicine, saving costs.

[0026] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
