Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer production equipment, specifically to a granular fertilizer coating and mixing device. Background Technology

[0002] Granular fertilizer refers to fertilizer made through a granulation process that has particles with a fixed shape and size. Some granular fertilizers have a coating material added, which coats the surface of the fertilizer particles with a layer of microbial powder to make slow-release or controlled-release granular fertilizer, which can prolong the fertilizer effect period and prevent nutrients from being lost too quickly.

[0003] In the prior art, utility model patent with announcement number CN217140137U provides a bio-fertilizer granule inoculation device, which includes a mixing mechanism and a feeding mechanism for introducing fertilizer granules and bacterial powder into the mixing mechanism. The mixing mechanism includes a base, a mixing cylinder, and a drive assembly for driving the mixing cylinder to rotate. The mixing cylinder is rotatably connected to the base. The mixing cylinder is inclined, and the height of the inlet of the mixing cylinder is higher than the height of the outlet of the mixing cylinder. The drive assembly is connected to the base, and the feeding mechanism is connected to the base.

[0004] In this bio-fertilizer granule inoculation device, fertilizer granules and bacterial powder can easily slide directly out of the mixing cylinder before being fully mixed. At the same time, the rotating stirring blades can easily compress fertilizer granules in the gaps between the stirring blades and the mixing plate and the inner wall of the cylinder. During mixing, powder flies out of the mixing cylinder, affecting personnel health, environmental cleanliness, and material utilization. To address these issues, we propose a granular fertilizer coating mixing device. Utility Model Content

[0005] The purpose of this invention is to provide a granular fertilizer coating and mixing device to solve the problems mentioned in the background art.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Pour fertilizer granules and microbial agent powder into the mixing cylinder through the opening. Then, start the electric drive gear to rotate. The gear meshes with the gear teeth, causing the mixing cylinder to rotate on limit ring one and limit ring two. The rotation of the mixing cylinder, in conjunction with the baffle, mixes the fertilizer granules and microbial agent powder. After mixing, drive the telescopic push rod to extend. The telescopic push rod pushes limit ring two upward, causing the mixing cylinder to flip on the support column through limit ring one. The mixing cylinder flips and separates from the roller, simultaneously causing the gear teeth to separate from the gear.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3A granular fertilizer coating and mixing device includes a base 1 and a mixing cylinder 2. The inner wall of the mixing cylinder 2 is provided with baffles (unlabeled), the length of which is parallel to the rotation axis of the mixing cylinder 2. Multiple baffles lift the fertilizer granules and bacterial powder inside the mixing cylinder 2. A mixing mechanism 3 is provided on the mixing cylinder 2 to drive the mixing cylinder 2 to rotate for mixing and to pour out the mixture inside the mixing cylinder 2. The mixing mechanism 3 includes a bracket 31 mounted on the base 1, and a motor (unlabeled) is mounted on the bracket 31. The output shaft of the motor is connected to a gear 32, which meshes with gear teeth 33 and is used to drive the mixing cylinder 2 to rotate. Limiting rings 34 and 35 are rotatably engaged on both sides of the gear teeth 33 on the mixing cylinder 2 to support the rotation of the mixing cylinder 2. The bottom of the limiting ring 34 is hinged. A support column 36 is attached to limit the movement of the first limiting ring 34. The bottom of the second limiting ring 35 is hinged to a telescopic push rod 37 for pushing the second limiting ring 35 up and down. The bracket 31 is divided into upper and lower parts. The upper part is a semi-circular ring structure and the lower part is a rod structure. The motor is located at the inner bottom of the upper part of the bracket 31. The inner diameter of the upper part of the bracket 31 is larger than the outer diameter of the mixing cylinder 2. The spacing of the openings in the upper part of the bracket 31 is larger than the outer diameter of the mixing cylinder 2. Rollers (not labeled) are rotatably provided on the inner ring of the upper part of the bracket 31 to support the rotation of the mixing cylinder 2. The rollers roll and contact the lower half of the curved surface of the mixing cylinder 2. The gear 32 is below the mixing cylinder 2. The gear teeth 33 are distributed in a ring on the curved surface of the mixing cylinder 2. The bottom end of the support column 36 is fixed on the base 1. The bottom end of the telescopic push rod 37 is hinged to the base 1.

[0026] Fertilizer granules and microbial agent powder are poured into mixing cylinder 2 through the opening. Then, the electric drive gear 32 is started to rotate. Gear 32 meshes with gear teeth 33, causing mixing cylinder 2 to rotate on limit ring 1 34 and limit ring 2 35. The rotation of mixing cylinder 2, in conjunction with the baffle, mixes the fertilizer granules and microbial agent powder. After mixing, the drive telescopic push rod 37 is extended. The telescopic push rod 37 pushes limit ring 2 35 upward, causing mixing cylinder 2 to flip on support column 36 through limit ring 1 34. The flipping of mixing cylinder 2 pours out the mixture inside, which facilitates the thorough mixing of fertilizer granules and microbial agent powder, and also makes it easy to remove the mixture from mixing cylinder 2.

[0027] The mixing cylinder 2 is provided with a sealing mechanism 4 at its open end. The sealing mechanism 4 is used to seal the opening of the mixing cylinder 2. The sealing mechanism 4 includes a fixing block 41 located at the opening of the mixing cylinder 2. The free end of the fixing block 41 is rotatably connected to a cover plate 42 for flipping and sealing the opening of the mixing cylinder 2. A torsion spring is provided at the connection between the fixing block 41 and the cover plate 42 for pushing the cover plate 42 to seal the opening of the mixing cylinder 2. One end of the torsion spring is connected to the cover plate 42, and the other end is connected to the fixing block 41.

[0028] Before adding materials, flip the cover plate 42 to open the mixing cylinder 2, pour the fertilizer granules and microbial agent powder into the mixing cylinder 2, then loosen the cover plate 42. The torsion spring returns to its original state and pushes the cover plate 42 back to its original position to seal the opening of the mixing cylinder 2. After the mixing cylinder 2 is flipped, the mixture inside moves to one side of the mixing cylinder 2. The mixture presses down on the cover plate 42, causing the cover plate 42 to flip open on the fixing block 41. The mixture is poured out through the opening of the mixing cylinder 2, preventing powder from flying out of the mixing cylinder 2 during mixing, ensuring personnel health, environmental cleanliness and efficient utilization of materials.

[0029] Working principle: In this invention, fertilizer granules and microbial agent powder are poured into the mixing cylinder 2 through its opening. Then, the electric drive gear 32 is activated to rotate. The gear 32 meshes with the gear teeth 33, causing the mixing cylinder 2 to rotate on the limiting rings 34 and 35. The rotation of the mixing cylinder 2, in conjunction with the baffle, mixes the fertilizer granules and microbial agent powder. After mixing, the drive telescopic push rod 37 extends, pushing the limiting ring 35 upward, causing the mixing cylinder 2 to flip on the support column 36 through the limiting ring 34. The mixing cylinder 2 flips and separates from the roller, simultaneously causing the gear teeth 33 to separate from the gear 32. The mixing cylinder 2 then flips and pours out the mixture inside the cylinder. This design facilitates thorough mixing of fertilizer granules and microbial powder, while also allowing for easy removal of the mixture from the mixing cylinder 2. Before adding the materials, the cover plate 42 is flipped to open the mixing cylinder 2. The fertilizer granules and microbial powder are then poured into the mixing cylinder 2. The cover plate 42 is then released, and the torsion spring returns to its original position, sealing the opening of the mixing cylinder 2. After the mixing cylinder 2 is flipped, the mixture inside moves to one side of the mixing cylinder 2. The mixture presses down on the cover plate 42, causing it to flip open on the fixing block 41. The mixture is then poured out through the opening of the mixing cylinder 2, preventing powder from flying out of the mixing cylinder 2 during mixing. This ensures personnel health, environmental cleanliness, and efficient material utilization.
