Description

Technical Field

[0001] This utility model relates to the field of seed coating technology, and in particular to a seed coating production device. Background Technology

[0002] The most crucial aspect of ecological restoration is the reconstruction of vegetation communities, which is constrained by factors such as the soil seed bank structure of the restoration area, natural seed replenishment, and damage to the seed bank from the external physical environment. Utilizing seed products to achieve large-scale vegetation restoration is a cutting-edge ecological restoration technology. By enhancing the water retention capacity, germination performance, and resilience to adverse hydrological conditions of natural seeds, the goal of large-scale vegetation restoration can be achieved.

[0003] The coating chamber is a key structure in seed coating equipment. Currently, the mainstream seed coating machines mainly consist of a cylindrical coating cylinder forming the coating chamber. Inside the cylinder is a pot-shaped seed-spinning disc. Seeds are placed in the disc, and a motor drives the disc to rotate, causing the seeds to tumble. Simultaneously, a coating agent is sprayed onto the seeds, coating their surface. This method has drawbacks: the centrifugal force experienced by seeds at different positions on the disc is not uniform, resulting in uneven contact between the seeds and the coating material. This reduces the yield and quality of coated seeds, wastes materials, and increases costs.

[0004] To address the aforementioned problems, this invention provides a seed coating production device to solve the technical problems of low seed coating qualification rate and poor seed coating quality in the prior art. Utility Model Content

[0025] 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.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This invention provides a seed coating production device that can improve the mixing efficiency of seeds and coating materials in the storage chamber, thereby improving the qualification rate of coated seeds and the quality of seed coating.

[0028] refer to Figure 1 and Figure 3 The seed coating production device disclosed in this embodiment of the present invention includes a coating treatment chamber, which includes a chamber body 1, a stirring device disposed in the chamber body 1, and a power device for providing power to the stirring device. The chamber body 1 is provided with an inlet 2 for seeds and their coating materials to enter the chamber body and a product outlet 3. The stirring device includes a stirring rod 4 and at least two sets of stirring blades 5 arranged sequentially from top to bottom along the stirring rod 4.

[0029] Because multiple sets of stirring blades 5 are arranged sequentially from top to bottom along the stirring rod 4, the seeds and coating materials, after entering the chamber 1 through the feed inlet 2, will be subjected to different stirring forces in different areas inside the chamber 1. This ensures thorough mixing and contact between the seeds and coating materials, improving the qualification rate of coated seeds and the uniformity of seed coating thickness, while reducing the residue rate. Of course, depending on actual needs, technicians can also consider setting multiple stirring rods 4 and equipping each stirring rod with stirring blades 5, as long as the requirement of thorough mixing of seeds and coating materials within the chamber is met.

[0030] Meanwhile, the seed coating production device also includes a support frame, a seed supply box 9, a material supply box 10, a film-forming agent supply box 11, and a water supply box 12. The support frame includes a support plate 13 and a support rod 14. The silo 1 is installed in the mounting hole of the support plate 13. The material supply box 10 is installed above the silo 1 via the support rod 14, and the outlet of the material supply box 10 is directly opposite the inlet 2 of the silo 1. The material supply box 10 is used to supply the silo 1 with the solid materials required for seed coating. The seed supply box 9 is installed on one side of the silo 1 via the support rod 14, and the seed supply... The seed supply box 9 is used to supply seeds to the storage chamber 1; the film-forming agent supply box 11 and the water supply box 12 are installed on the other side of the storage chamber 1 via the support rod 14, and are used to supply the storage chamber 1 with the film-forming agent and water required for seed coating, respectively; by integrating the coating treatment chamber, seed supply box 9, material supply box 10, film-forming agent supply box 11 and water supply box 12 via the support frame, the seed coating production device has the functions of autonomous material feeding, seed supply, film-forming agent supply and water supply. Combined with the production controller 19 and the batching controller 18, the requirements for autonomous processing can be realized.

[0031] refer to Figure 2 In this embodiment, each set of stirring blades 5 has an S-shaped structure and is evenly arranged around the stirring rod 4. Each set of stirring blades 5 includes multiple fan blades, which are evenly arranged around the stirring rod. The S-shaped stirring blades 5, when rotating, can simultaneously generate axial movement along the axis of the stirring rod 4 and radial movement outwards, thus promoting the seeds and coating material to form axial and radial movement paths within the chamber, significantly reducing mixing dead zones. Simultaneously, the streamlined structure of the stirring blades 5 reduces mechanical impact on the seeds, thereby lowering the risk of seed breakage and improving the yield.

[0032] In this embodiment, the upper section of the container 1 is a barrel structure, and the lower section of the container 1 is a conical structure. The inlet 2 is located at the top of the container, and the outlet 3 is located on the side wall of the lower section of the container 1. The shaft of the stirring rod 4 coincides with the axis of the container 1. After the seeds and coating materials enter through the inlet 2, they first come into contact with the uppermost set of stirring blades 5 to perform preliminary mixing of the seeds and various coating materials. The main function of this stage is to premix the seeds and coating materials. After premixing, the seeds and coating materials pass through the stirring blades 5 arranged in other axes one after another, gradually forming a coating layer structure of uniform thickness on the seed surface. After the finished product enters the lower section of the conical container 1, it is closer to the stirring rod 4 area and therefore will not be subjected to a strong stirring force from the stirring blades 5, thus avoiding secondary damage to the seed coating layer.

[0033] In this embodiment, the bottom of the chamber is provided with a through hole 8 for the stirring rod 4 to pass through. The power unit includes a drive motor 7, which is located below the chamber 1. The output shaft of the power unit is coaxially connected to the end of the stirring rod 4 that passes through the through hole 8. By placing the drive motor 7 on the outside of the chamber 1, the heat of the drive motor 7 can be avoided from affecting the seed coating production process, thereby improving the yield of the product.

[0034] In this embodiment, a sealing ring 6 is provided between the through hole 8 and the stirring rod 4 to prevent material from being exposed through the through hole 8. This avoids the leakage of film-forming agent, water, and small-diameter particles through the gap between the through hole 8 and the stirring rod 4, which would cause cost waste and damage to the drive motor 7. Of course, depending on the actual setup requirements, technicians may also consider setting the drive motor 7 in other positions in the chamber 1, as long as it can meet the requirements for driving the stirring rod 4 inside the chamber 1 to rotate.

[0035] In this embodiment, the material supply box 10 is provided with multiple partitions to form multiple accommodating spaces inside the material supply box 10, which are used to simultaneously accommodate multiple materials required for seed coating. At the same time, the top of the material supply box 10 is provided with baffles, the number of baffles being the same as the number of accommodating spaces. When a specific coating material is needed, only the baffle of the corresponding accommodating space needs to be opened, eliminating the need for manual repeated addition to the box, thus saving labor costs.

[0036] In this embodiment, the outlet of the seed supply box 9 is higher than the inlet 2 of the silo, and a conveying slide 15 is provided between the outlet of the seed supply box 9 and the inlet 2 of the silo, so that the seeds enter the silo 1 from the seed supply box 9 through the conveying slide 15 under the action of gravity; by utilizing the gravity of the seeds, automatic seed replenishment can be realized, reducing the overall power consumption of the device and further reducing the cost of use.

[0037] In this embodiment, the outlet of the film-forming agent supply box 11 is equipped with a film-forming agent atomizing device 16, which is directly connected to the interior of the chamber 1, so that the film-forming agent is distributed in the chamber 1 in a mist form and participates in stirring. The outlet of the water supply box 12 is equipped with a water atomizing device 17, which is directly connected to the interior of the chamber 1, so that the water is distributed in the chamber 1 in a mist form and participates in stirring. The mist outlets of the film-forming agent atomizing device 16 and the water atomizing device 17 are directly connected to the interior of the chamber, which reduces the volatilization and diffusion of the atomized material to the outside.

[0038] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
