Description

Technical Field

[0001] This utility model relates to the field of pesticide and micro-fertilizer formulation technology, and more specifically to a cotton seed coating device. Background Technology

[0002] In existing technologies, the main purpose of cotton seed coating is to uniformly coat the seed surface with a seed coating agent containing pesticides, fertilizers, growth regulators, and other ingredients to prevent and control pests and diseases, provide nutrients, regulate growth, retain moisture, improve the soil environment, facilitate mechanized sowing, thereby improving seed quality and stability, and ensuring high, stable, and high-quality cotton yields.

[0003] Traditionally, cotton seeds are coated with a single layer. A single layer of coating makes it difficult to ensure that the seed coating agent is evenly distributed on the seed surface. This can easily lead to some seeds being coated too thickly, too thinly, or even not coated at all, which affects seed germination and seedling growth. Furthermore, a single layer of coating cannot accurately provide the necessary nutrients and regulatory substances according to the different stages of cotton seed growth, which is not conducive to the regulation of seed growth and development throughout the entire process.

[0004] Therefore, how to provide a new cotton seed coating device that can effectively improve the quality of cotton seed coating and achieve multi-layer coating is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a cotton seed coating device, which aims to solve the technical problem that the traditional single-layer coating of cotton seeds is not conducive to the regulation of the entire growth and development of seeds.

[0006] A cotton seed coating device, comprising:

[0007] cylindrical body;

[0008] The mixing mechanism consists of multiple mixing mechanisms arranged alternately along the height of the cylinder inside the cylinder. The feed inlet of the lower mixing mechanism is opposite to the discharge outlet of the upper mixing mechanism.

[0009] The drying mechanism has its inlet facing the outlet of the mixing mechanism located at the bottom.

[0010] Through the above technical solution, this utility model utilizes multiple stirring mechanisms arranged in a staggered pattern along the height of the cylinder to ensure thorough mixing of seeds with various coating agents, achieving multi-layer coating. Simultaneously, the inlet and outlet of adjacent stirring mechanisms are opposite each other, forming a continuous coating process and improving coating efficiency. The drying mechanism, opposite the outlet of the lowest stirring mechanism, can promptly dry the seeds, preventing coating agents from clumping and falling off. Furthermore, this compact structure and smooth process provide a basic framework for subsequent layered coating, meeting the needs of cotton seeds at different growth stages.

[0011] Preferably, the stirring mechanism includes a stirring plate, stirring blades, and a servo motor. The upper surface of the stirring plate has a stirring groove. The stirring blades are rotatably connected to the bottom surface of the stirring groove. The fixed end of the servo motor is fastened to the lower surface of the stirring plate. The power output end of the servo motor passes through the bottom surface of the stirring groove and is fixedly connected to the stirring blades. A discharge port is provided at the edge of the bottom surface of the stirring groove. The feed position of the stirring mechanism is located above the center of the stirring groove.

[0012] Preferably, the stirring blade includes a rotating shaft, a blade skeleton, and bristles. The rotating shaft is arranged coaxially with the stirring plate. The bottom end of the rotating shaft is fixedly connected to the power output end of a servo motor. Multiple blade skeletons are arranged in a circumferential array along the rotating shaft. The bristles are fixedly connected to the lower end of the blade skeleton.

[0013] Preferably, the blade skeleton is arranged to bend radially along the rotation axis, and the bending direction is towards the rear of the rotation axis.

[0014] Preferably, the blade skeleton is arranged at an angle along the axial direction of the rotation axis, and the angle is directed forward of the rotation direction of the rotation axis.

[0015] Preferably, it also includes a coating agent inlet pipe, which is fixedly connected to the side wall of the cylinder, and the outlet ends of the multiple coating agent inlet pipes are respectively arranged opposite to the inlet positions of the multiple stirring mechanisms.

[0016] Preferably, it also includes a storage bin, which is fixedly connected to the top of the cylinder, and the outlet of the storage bin is arranged opposite to the feed position corresponding to the uppermost stirring mechanism.

[0017] Preferably, the bottom surface of the storage compartments is arranged in a clustered manner, and the outlet of the storage compartments is located at the lowest point of the bottom surface of the storage compartments.

[0018] Preferably, there are three mixing mechanisms and three coating agent inlet pipes.

[0019] Preferably, the three stirring mechanisms sequentially generate, from top to bottom, a seed coat and seed-binding layer, a nutrient and growth regulating layer, and a protective and functional strengthening layer on the surface of the cotton seeds.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a cotton seed coating device with the following beneficial effects: In the two adjacent stirring mechanisms, the inlet of the lower stirring mechanism is arranged opposite to the outlet of the upper stirring mechanism, forming a continuous coating process. This allows the cotton seeds to automatically flow to the next stirring mechanism for the next layer of coating under gravity, eliminating the need for additional conveying equipment, reducing intermediate links, and effectively improving coating efficiency. The inlet of the drying mechanism is arranged opposite to the outlet of the lowermost stirring mechanism, allowing for timely drying of the cotton seeds after the final layer of coating is completed. This prevents the coating agent from clumping and falling off, ensuring the quality and stability of the coating, and also avoiding problems such as seed germination caused by untimely drying.

Detailed Implementation

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] See appendix Figure 1-7 This utility model discloses a cotton seed coating device, including: a cylinder 1, a stirring mechanism 2, and a drying mechanism;

[0031] Multiple mixing mechanisms 2 are arranged alternately along the height direction of the cylinder 1 inside the cylinder 1. The feeding position corresponding to the lower mixing mechanism 2 of two adjacent mixing mechanisms 2 is arranged opposite to the discharge port corresponding to the upper mixing mechanism 2.

[0032] The inlet of the drying mechanism is arranged opposite to the outlet of the stirring mechanism 2 located at the bottom.

[0033] In this embodiment, the drying mechanism includes a drying cylinder 31, spiral blades 32, a servo motor 34, an air storage chamber 35, and a drying mechanism. The drying cylinder 31 is fixedly connected to the cylinder body 1, with one end closed and the other end open. The closed end of the drying cylinder 31 is located inside the cylinder body 1. An inlet is provided on the side wall of the drying cylinder 31 inside the cylinder body 1, and it is arranged opposite to the outlet corresponding to the bottommost stirring mechanism 2. The spiral blades 32 are coaxially arranged with the drying cylinder 31 and rotatably connected to the inner wall of the drying cylinder 31. The fixed end of the second motor 34 is fixedly connected to the closed end of the drying cylinder 31. The power output end of the second servo motor 34 passes through the closed end of the drying cylinder 31 and is fixedly connected to the spiral blade 32. There are two air storage chambers 35, which are symmetrically arranged on both sides of the drying cylinder 31. The air storage chambers 35 are connected to the interior of the drying cylinder 31 through the connecting hole 351. The drying mechanism is fixedly connected to the inner wall of the cylinder 1. The output end of the drying mechanism is connected to the interior of the air storage chamber 35 through a pipeline to dry the cotton seeds coated in the drying cylinder 31.

[0034] Specifically, the drying mechanism includes a heating fan 331, an air inlet pipe 332, and a hot air distribution chamber 333. The heating fan 331 is fixedly connected to the cylinder 1. The air inlet port of the heating fan 331 is connected to the outside air through the air inlet pipe 332, and the air outlet port of the heating fan 331 is connected to two air storage chambers 35 through pipelines via the hot air distribution chamber 333.

[0035] In some embodiments, the stirring mechanism 2 includes a stirring plate 21, stirring blades 22, and a servo motor 23. The side wall of the stirring plate 21 is fixedly connected to the inner wall of the cylinder 1. A stirring groove 211 is formed on the upper surface of the stirring plate 21. The stirring blades 22 are rotatably connected to the bottom surface of the stirring groove 211. The fixed end of the servo motor 23 is fastened to the lower surface of the stirring plate 21. The power output end of the servo motor 23 passes through the bottom surface of the stirring groove 211 and is fixedly connected to the stirring blades 22. A discharge port is formed at the edge of the bottom surface of the stirring groove 211. The feeding position of the stirring mechanism 2 is located above the center of the stirring groove 211.

[0036] In other embodiments, the stirring blade 22 includes a rotating shaft 221, a blade frame 222, and bristles 223. The rotating shaft 221 is coaxially arranged with the stirring disc 21, and the bottom end of the rotating shaft 221 is fixedly connected to the power output end of the servo motor 23. Multiple blade frames 222 are arranged in a circumferential array along the rotating shaft 221, and the bristles 223 are fixedly connected to the lower end of the blade frames 222. Thus, the blade frame 222 provides a robust support structure for the bristles 223, enabling the stirring blade 22 to maintain a stable shape and strength during rotation, and preventing deformation or damage.

[0037] In one embodiment, the blade frame 222 is arranged in a radially bent manner along the rotation shaft 221, with the bending direction facing the rear of the rotation direction of the rotation shaft 221. Thus, the blade frame 222, arranged in a radially bent manner along the rotation shaft 221, can gradually push the mixture of cottonseed and coating agent towards the edge of the bottom surface of the mixing tank 211 during rotation, and discharge it from the outlet.

[0038] In one embodiment, the blade frame 222 is arranged obliquely along the axial direction of the rotation shaft 221, and its oblique direction is towards the front of the rotation direction of the rotation shaft 221. Thus, by using the blade frame 222 arranged obliquely along the axial direction of the rotation shaft 221, the mixture of cottonseed and coating agent can always accumulate on the bottom surface of the mixing tank 211 during the agitation process, making the agitation process more stable.

[0039] In some embodiments, the system further includes a coating agent inlet pipe 4, which is fixedly connected to the side wall of the cylinder 1. The outlet ends of the plurality of coating agent inlet pipes 4 are respectively arranged opposite to the inlet positions of the plurality of stirring mechanisms 2. Thus, by arranging the plurality of coating agent inlet pipes 4 opposite to the inlet positions of the plurality of stirring mechanisms 2, the corresponding coating agent can be added according to the requirements of different coating layers, thereby achieving precise ingredient dispensing and layered coating.

[0040] In some embodiments, a storage bin 5 is further included. The storage bin 5 is fixedly connected to the top of the cylinder 1, and the outlet of the storage bin 5 is arranged opposite to the feed position corresponding to the uppermost stirring mechanism 2. Thus, the storage bin 5 is fixedly connected to the top of the cylinder 1, and its outlet is arranged opposite to the feed position corresponding to the uppermost stirring mechanism 2, which can conveniently store a large amount of cotton seeds and continuously and stably supply seeds to the stirring mechanism during the coating process, ensuring the continuity and stability of the coating operation and improving production efficiency.

[0041] In this embodiment, the bottom surface of the storage chamber 5 is arranged in a clustered manner, and the outlet of the storage chamber 5 is located at the lowest point of the bottom surface of the storage chamber 5. Thus, the clustered arrangement of the bottom surface of the storage chamber 5 and the location of the outlet at the lowest point of the bottom surface ensures that cotton seeds can flow smoothly from the storage chamber 5 into the stirring mechanism 2 under the action of gravity, avoiding the accumulation or blockage of seeds in the storage chamber 5 and ensuring the smoothness and uniformity of seed supply.

[0042] In some specific embodiments, there are three stirring mechanisms 2 and three coating agent feed pipes 4.

[0043] In other specific embodiments, the three stirring mechanisms 2 sequentially generate, from top to bottom, a seed coat and seed tightly bound layer, a nutrient and growth regulating layer, and a protective and functional strengthening layer on the surface of the cotton seeds.

[0044] The main components and functions of the seed coat's tightly bound layer to the seed:

[0045] Film-forming agents: These are the basic substances that form the seed coating. They allow other components to adhere evenly to the seed surface and form a thin film. For example, some film-forming agents are high-molecular-weight polymers, such as polyvinyl alcohol. This film prevents excessive water loss from the seed's interior and also prevents external moisture and harmful substances such as pests and diseases from penetrating the seed too quickly.

[0046] Some systemic fungicides and insecticides: Systemic fungicides, such as fludioxonil, can be absorbed by the seed. When pathogens invade the seed, the fungicide can act inside the seed to kill the pathogens. Systemic insecticides, such as thiamethoxam, can also be absorbed by the seed. When pests feed on the seed, the insecticide enters the pest's body and kills it. These agents are mainly used to protect the seed in the early stages of germination, preventing pests and diseases from damaging the seed from within.

[0047] Main components and functions of the nutrient and growth regulator layer:

[0048] Nutrients: This includes macronutrients (such as nitrogen, phosphorus, and potassium) and micronutrients (such as zinc, iron, and manganese) required for cotton seed germination and early seedling growth. These nutrients provide sufficient nourishment for the seeds, promoting germination and seedling growth. For example, phosphorus promotes root development during seed germination, enabling seedlings to take root in the soil more quickly.

[0049] Growth regulators, such as gibberellins and indoleacetic acid. Gibberellins can break seed dormancy, promote seed germination, and accelerate physiological activities within the seed. Indoleacetic acid can regulate cell growth and division, contributing to the elongation of seedling stems and roots.

[0050] Main components and functions of the protective and functional enhancement layer:

[0051] Protective fungicides and insecticides: Unlike the systemic fungicides and insecticides in the inner layer, those in this layer primarily act as protectants. For example, a protective fungicide like mancozeb can form a protective film around the seed; when pathogens come into contact with this film, they are killed, thus preventing infection of the seeds and seedlings. Insecticides like lambda-cyhalothrin can repel or kill pests that come into contact with the seeds, protecting them from direct damage by external pests.

[0052] Water-retaining agents: Water-retaining agents can absorb and retain large amounts of water, providing favorable moisture conditions for seed germination and seedling growth. For example, some water-retaining agents are superabsorbent resins that can absorb hundreds of times their own weight in water. When soil moisture is insufficient, water-retaining agents can slowly release water for use by seeds and seedlings.

[0053] Colorants and repellents (optional): Colorants give coated seeds a distinct color, making them easier to identify and handle, and preventing them from being confused with other substances. Repellents, such as bird repellents, can prevent birds and other animals from pecking at the seeds.

[0054] The specific principle and usage of the cotton seed coating device provided in this embodiment are as follows:

[0055] Storage bin 5 stores a large amount of cotton seeds. Its bottom surface is gathered and the outlet is located at the lowest point. Under the action of gravity, the cotton seeds flow from the outlet of storage bin 5 to the feed position of the stirring mechanism 2 located at the top.

[0056] The outlet end of the coating agent inlet pipe 4 is opposite to the inlet position of the mixing mechanism 2. The coating agent is added from the coating agent inlet pipe 4 and mixed with cotton seeds in the mixing mechanism 2.

[0057] Servo motor 23 drives the stirring blade 22 to rotate. The rotation shaft 221 of the stirring blade 22 is coaxially arranged with the stirring plate 21. The blade frame 222 is radially bent and axially inclined along the rotation shaft 221. The bending direction faces the rear of the rotation direction of the rotation shaft 221, and the inclined direction faces the front of the rotation direction of the rotation shaft 221. The bristles 223 are fixedly connected to the lower end of the blade frame 222. This design allows the blade frame 222 to gradually push the mixture of cottonseed and coating agent towards the bottom edge of the stirring tank 211 when it rotates, and discharge it from the outlet, thus achieving preliminary coating.

[0058] Multiple mixing mechanisms 2 are staggered along the height of the cylinder 1. In two adjacent mixing mechanisms 2, the feed position of the lower mixing mechanism 2 is opposite to the discharge port of the upper mixing mechanism 2. Cotton seeds flow from the discharge port of the upper mixing mechanism 2 into the feed position of the lower mixing mechanism 2 in sequence, and are coated in multiple layers in sequence to form a seed coating and seed tightly bound layer, a nutrient and growth regulation layer, and a protection and functional enhancement layer.

[0059] After multi-layer coating, the cotton seeds are discharged from the outlet of the bottommost stirring mechanism 2 and enter the drying mechanism. The inlet of the drying mechanism is arranged opposite to the outlet of the bottommost stirring mechanism 2, and it includes a drying cylinder 31, spiral blades 32, servo motor 34, air storage chamber 35, and drying mechanism. Servo motor 34 drives the spiral blades 32 to rotate, causing the cotton seeds to tumble and move inside the drying cylinder 31. At the same time, the heating fan 331 heats the outside air and then conveys it to the air storage chamber 35 through the hot air distribution chamber 333 and the connecting hole 351, and then into the drying cylinder 31 to dry the cotton seeds and prevent the coating agent from clumping and falling off.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
