Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, and more specifically, it relates to a seed coating device for corn planting. Background Technology

[0002] Seed coating technology is a crucial step before corn planting. By coating the surface of seeds with a coating agent containing fungicides, insecticides, and nutrients, the seed's resistance to diseases and pests can be effectively improved, its stress resistance enhanced, and seedlings can be encouraged to grow vigorously. This is of great significance for improving corn yield and quality.

[0003] Most corn seed coating devices lack a dedicated drying mechanism. After coating, the coating agent remains moist. If this moisture is not removed promptly, the seeds easily clump together, causing the coating agent to detach and reducing its effectiveness. Furthermore, clumps of seeds can clog the seeder during sowing, increasing the difficulty of subsequent operations. Therefore, this paper researches and improves existing structures and address their shortcomings to provide a corn seed coating device with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a seed coating device for corn planting, which is achieved by the following specific technical means:

[0005] A seed coating device for corn cultivation includes a frame and a coating chamber mounted on the frame. A stirring assembly is installed inside the frame, comprising a drive motor and a connecting shaft. A spiral blade is fixedly mounted on the connecting shaft. The drive motor drives the connecting shaft to rotate. A cover plate is installed at the upper end of the coating chamber. A hinge shaft is fixedly mounted at one end of the cover plate, and the cover plate is hinged to one end of the coating chamber via the hinge shaft. An extension ring is connected to the middle of the upper end of the cover plate. A fan is installed at the upper end of the extension ring, and a grid plate is fixedly connected to the bottom end of the extension ring. A heating wire is installed inside the extension ring, located between the grid plate and the fan.

[0006] Furthermore, the bottom of the coating compartment is designed in a conical shape, and a discharge port is provided at the bottom of the coating compartment. A removable blocking plate is installed at the discharge port.

[0007] Furthermore, the drive motor is fixedly installed at the middle of the bottom of the frame, and the output shaft of the drive motor passes through the frame and is inserted into the coating compartment. The output shaft of the drive motor is fixedly connected to a hexagonal connecting rod, which is located in the middle of the coating compartment.

[0008] Furthermore, the connecting shaft has a hexagonal groove inside that is adapted to the hexagonal connecting rod, and the connecting shaft is fitted onto the hexagonal connecting rod through the hexagonal groove.

[0009] Furthermore, wheels and handles are respectively installed on the bottom and top of one side of the frame.

[0010] Furthermore, an air outlet pipe is installed on one side of the upper end of the cover plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] I. This seed coating device for corn planting has an extension ring connected to the upper end of the cover plate, and integrates a drying structure of "fan + heating wire": the fan draws outside air downward into the extension ring, and the heating wire heats the air to a suitable temperature. The hot air enters the coating chamber through the grid plate, making full contact with the seeds during stirring, evaporating the moisture in the coating agent in real time, and promoting the rapid solidification and adhesion of the coating agent to the seed surface; at the same time, the air outlet on the cover plate can promptly discharge moisture and excess hot air from the chamber, maintaining a dry environment inside the chamber, fundamentally avoiding the problem of seed adhesion, reducing coating agent detachment, and ensuring coating stability.

[0013] Second, the drive motor drives the connecting shaft to rotate through the hexagonal connecting rod. When the spiral blades rotate, they can not only transport the seeds at the bottom of the coating bin upward, but also drive the material in the bin to make a circular motion, forming a dual effect of "up and down turning + circular stirring". This stirring method can break the material stratification phenomenon, so that the corn seeds can fully contact the coating agent and ensure that the coating agent is evenly attached to the seed surface.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a seed coating device for corn planting, including a frame 1 and a coating chamber 2 installed on the frame 1. A stirring assembly is provided inside the frame 1. The stirring assembly includes a drive motor 3 and a connecting shaft 4. A spiral blade 41 is fixedly installed on the connecting shaft 4. The drive motor 3 is used to drive the connecting shaft 4 to rotate. A cover plate 5 is installed on the upper end of the coating chamber 2. A hinge shaft 51 is fixedly installed on one end of the cover plate 5. The cover plate 5 is hinged to one end of the coating chamber 2 through the hinge shaft 51, which facilitates the opening and closing of the cover plate 5.

[0026] An extension ring 6 is connected to the middle of the upper end of the plate 5. A blower 7 is installed at the upper end of the extension ring 6, and a grid plate 61 is fixedly connected to the bottom end of the extension ring 6. A heating wire 62 is installed inside the extension ring 6, and the heating wire 62 is located between the grid plate 61 and the blower 7. The blower 7 draws outside air downward into the extension ring 6 and simultaneously powers the heating wire 62 inside the extension ring 6 (located between the grid plate 61 and the blower 7). The heating wire 62 heats up and heats the air drawn in by the blower 7 to a suitable temperature (the temperature can be adjusted by a conventional temperature control component). The hot air enters the coating chamber 2 through the connection between the extension ring 6 and the cover plate 5, comes into contact with the seeds being stirred, and gradually evaporates the moisture in the coating agent on the seed surface, so that the coating agent solidifies and adheres to the seed surface, preventing the seeds from sticking together due to the coating agent not being dry.

[0027] The bottom of the coating compartment 2 is designed in a conical shape, and the bottom of the coating compartment 2 is provided with a discharge port 21, and a removable blocking plate 22 is installed at the discharge port 21;

[0028] The drive motor 3 is fixedly installed at the bottom center of the frame 1. The output shaft of the drive motor 3 passes through the frame 1 and is inserted into the coating compartment 2. The output shaft of the drive motor 3 is fixedly connected to a hexagonal connecting rod 31. The hexagonal connecting rod 31 is located in the center of the coating compartment 2. The inside of the connecting shaft 4 is provided with a hexagonal groove that matches the hexagonal connecting rod 31. The connecting shaft 4 is fitted onto the hexagonal connecting rod 31 through the hexagonal groove for easy installation.

[0029] Wheels 11 and handles 12 are installed on the bottom and top of one side of the frame 1, respectively. The user tilts the frame 1 so that the wheels 11 on the bottom of one side of the frame 1 contact the ground, and then pulls the handle 12 to move the device, making it more flexible to use.

[0030] An air outlet pipe 52 is installed on one side of the upper end of the cover plate 5. The moisture and excess hot air generated during drying in the coating chamber 2 are discharged outside the chamber through the air outlet pipe 52 installed on one side of the upper end of the cover plate 5, maintaining the air pressure balance and dry environment inside the chamber.

[0031] The working principle of this embodiment:

[0032] Open the cover plate 5 by flipping it upwards through the hinge shaft 51 at one end of the cover plate 5 (because the cover plate 5 is hinged to the coating chamber 2, it can be opened and closed flexibly). At the same time, check the removable blocking plate 22 at the bottom outlet 21 of the coating chamber 2 to ensure that the blocking plate 22 is fully installed to prevent material leakage during subsequent feeding and mixing. Put the corn seeds to be coated into the coating chamber 2 and start the drive motor 3 fixedly installed at the bottom center of the frame 1. The output shaft of the drive motor 3 passes through the frame 1 and extends into the coating chamber 2. The hexagonal connecting rod 31 fixedly connected to the end of its output shaft rotates with the motor. Since the connecting shaft 4 has a hexagonal groove that matches the hexagonal connecting rod 31, and the connecting shaft 4 is sleeved on the hexagonal groove, the hexagonal connecting rod 31 rotates with the motor. The hexagonal structure on the connecting rod 31 can prevent transmission slippage, so that the hexagonal connecting rod 31 synchronously drives the connecting shaft 4 to rotate. The spiral blade 41 fixedly installed on the connecting shaft 4 rotates together with the connecting shaft 4. Then, the coating agent corresponding to the corn seeds is poured into the corn seeds in the coating chamber 2. During the rotation, the spiral structure of the spiral blade 41 will produce a dual effect of "up and down turning + circular stirring" on the corn seeds and coating agent in the coating chamber 2 - both conveying the material at the bottom of the chamber upward and driving the material in the chamber to move in a circular motion, breaking the material layering, so that the corn seeds can fully contact the coating agent and achieve the initial uniform adhesion of the coating agent on the seed surface.

[0033] After the mixing assembly has been running for a period of time, cover plate 5 is closed, and the blower 7 installed on the upper port of extension ring 6 is turned on. The blower 7 draws outside air downward into the extension ring 6, and at the same time, it energizes the heating wire 62 inside the extension ring 6 (located between the grid plate 61 and the blower 7). The heating wire 62 heats up, heating the air drawn in by the blower 7 to a suitable temperature (the temperature can be adjusted by a conventional temperature control component). The hot air enters the coating chamber 2 through the connection between the extension ring 6 and cover plate 5, comes into contact with the seeds being mixed, and gradually evaporates the moisture in the coating agent on the seed surface. The coating agent is cured and adhered to the seed surface to prevent the seeds from sticking together due to the coating agent not being dry. The moisture and excess hot air generated during drying in the coating chamber 2 are discharged outside the chamber through the air outlet pipe 52 installed on one side of the upper end of the cover plate 5, maintaining the air pressure balance and dry environment inside the chamber. The removable plug plate 22 at the bottom outlet 21 of the coating chamber 2 can be manually removed (the plug plate 22 can be connected and fixed to the coating chamber 2 with screws). Because the bottom of the coating chamber 2 is conical, the coated seeds in the chamber can automatically converge to the outlet 21 at the bottom center under the action of gravity and finally flow out from the outlet 21.

[0034] When the device needs to be moved, the user tilts the frame 1 so that the wheels 11 on the bottom side of the frame 1 contact the ground, and then pulls the handle 12 to move the device, making it more flexible to use. The connecting shaft 4 and the spiral blade 41 are made of nylon, which reduces damage to the corn seeds.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
