Description

Technical Field

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

[0002] As one of the world's most important food crops, rice's planting area and yield are directly related to global food security. To improve rice yield and quality, and to ensure successful germination, growth, and resistance to pests and diseases after sowing, seed treatment technology has become crucial. Seed coating is an advanced seed treatment method that effectively promotes seed germination, enhances seedling resistance, and reduces field management costs by coating the seed surface with a layer containing pesticides, fertilizers, microorganisms, or other active ingredients.

[0003] Utility model patent CN215835866U discloses a seed coating machine, including a drive motor, a rotating shaft, and a frame. A coating tank is installed inside the frame, and a feeding hopper is installed on one side of the top of the coating tank. A baffle is installed at the bottom of one side of the feeding hopper. A discharge port is installed on one side of the bottom of the frame. The rotating shaft passes through the bottom of the coating tank, and a second conveyor belt is installed outside the rotating shaft. The drive motor is installed on one side inside the frame, and a first conveyor belt is installed at the output end of the drive motor. A belt is installed between the first and second conveyor belts. A spraying mechanism is provided. Coating powder or coating liquid is fed into the feeding hopper. A pump operates, and the material flows out along the discharge pipe and then into the spray nozzle, which sprays the coating powder or coating liquid into the coating tank. By spraying the coating powder or coating liquid, the coating machine can improve the coating effect on seeds, thus improving seed quality.

[0004] In the above technical solution, in order to improve the mixing effect, a nozzle is set on the top of the coating tank to spray the coating agent into the coating tank. However, the position of the nozzle is fixed, and it can only spray a part of the coating tank. Then, the seeds are moved by stirring, which moves the coating agent and mixes the coating agent with the seeds. This mixing method is inefficient and the seed coating is uneven, resulting in poor mixing effect. Utility Model Content

[0044] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] like Figure 1-6 As shown, the present invention provides a rice seed coating device, which includes a frame 1, a hopper 2, a stirring mechanism 3, a spraying mechanism 4, a linkage mechanism 5, and a support mechanism 6.

[0046] Among them, frame 1 is a frame support structure, which is used to support the installation and fixation of hopper 2 and various components.

[0047] The hopper 2 is used to hold seeds and provide space for mixing seeds and coating agents. The hopper 2 is fixedly installed on the frame 1. The lower part of the hopper 2 is conical. A discharge gate 201 is fixedly installed on the inclined surface of the lower part of the hopper 2 and is connected to the interior of the hopper 2. When the seeds are coated, the discharge gate 201 is closed to prevent the seeds from spilling. After the coating is completed, the discharge gate 201 is opened and the seeds in the hopper 2 flow out from the discharge gate 201.

[0048] The stirring mechanism 3 is used to stir the seeds to ensure that the seeds and coating agent are fully mixed. The stirring mechanism 3 includes a rotating shaft 31, an auger 32, and a drive motor 33. The rotating shaft 31 is disposed in the middle of the bottom side of the hopper 2, and a bearing is provided between the rotating shaft 31 and the hopper 2, and the two are rotatably connected through the bearing. The auger 32 is fixedly disposed on the rotating shaft 31. The drive motor 33 is fixedly disposed on the frame 1, and the output end of the drive motor 33 is connected to the rotating shaft 31 through a belt. The drive motor 33 drives the rotating shaft 31 to rotate through the belt, thereby driving the auger 32 to rotate. During the rotation, the auger 32 stirs the seeds in the hopper 2 so that the seeds can be fully mixed with the coating agent. In order to reduce the rotation speed of the rotating shaft 31, the diameter of the pulley at the output end of the drive motor 33 is smaller than the diameter of the pulley on the rotating shaft 31.

[0049] The spraying mechanism 4 is used to spray coating agent into the hopper 2. The spraying mechanism 4 includes a water supply pipe 41 and a spray pipe 42. The inside of the rotating shaft 31 is hollow. The water supply pipe 41 is installed inside the rotating shaft 31, and both ends of the water supply pipe 41 pass through the rotating shaft 31. The spray pipe 42 is fixedly installed on the top side of the water supply pipe 41 and connected to it. The water supply pipe 41 is rotatably connected to the rotating shaft 31. The rotation of the water supply pipe 41 can drive the spray pipe 42 to rotate, realizing rotational spraying and making the spraying more uniform.

[0050] To increase the spraying range, such as Figure 4 As shown, multiple spray pipes 42 are provided on the top side of the water supply pipe 41, and the multiple spray pipes 42 are arranged circumferentially around the center line of the water supply pipe 41, so that the coating agent can come into better contact with the seeds, improve the mixing effect, and improve the uniformity of seed coating.

[0051] The spraying mechanism 4 also includes a chemical tank 43 and a pressure pump 44. The chemical tank 43 is fixedly mounted on the frame 1 and is used to store the coating agent. The pressure pump 44 is fixedly mounted on the frame 1, and the input end of the pressure pump 44 is connected to the chemical tank 43, and the output end of the pressure pump 44 is connected to the water supply pipe 41. The coating agent is poured into the chemical tank 43, and the pressure pump 44 can transport the coating agent in the chemical tank 43 to the water supply pipe 41, and then to the spray pipe 42, and finally sprayed out from the spray pipe 42. In addition, the connection between the output end of the pressure pump 44 and the water supply pipe 41 should be rotatable to avoid affecting the rotation of the water supply pipe 41.

[0052] The linkage mechanism 5 is used for transmission between the rotating shaft 31 and the water supply pipe 41. The linkage mechanism 5 includes a drive turntable 51, a transmission mechanism 52, a driven turntable 53, and a stop block 54. The drive turntable 51 has a disc-shaped overall appearance and is sleeved on the bottom side of the rotating shaft 31 and fixedly connected to it. The transmission mechanism 52 includes a stop rod 521, a rod seat 522, a push rod 523, a connecting sleeve 524, and a spring 525. The rod seat 522 is fixedly mounted on the drive turntable 51. The rod seat 522 has a circular hole for installing the push rod 523. The push rod 523 is inserted into the circular hole and slidably connected to the rod seat 522. In order to prevent the push rod 523 from coming out, a stop block is provided at one end of the push rod 523. The stop block abuts against the rod seat 522 to limit the push rod 523. The connecting sleeve 524 is connected by a threaded connection. A spring 525 is fitted onto the end of the push rod 523 furthest from the rod seat 522. The two ends of the spring 525 abut against the connecting sleeve 524 and the rod seat 522, respectively. The spring 525 provides elastic support for the push rod 523, allowing it to automatically return to its original position. The abutment 521 is connected to the connecting sleeve 524 via a threaded connection and is perpendicular to the drive turntable 51. The driven turntable 53 is a disc-shaped structure with an open top. It is fitted onto the bottom side of the water supply pipe 41 and fixedly connected to it. The driven turntable 53 is parallel to the drive turntable 51. The abutment block 54 is fixedly mounted on the inner wall of the driven turntable 53. The abutment 521 abuts against the abutment block 54. When the abutment 521 abuts against the abutment block 54, the drive turntable 51 pushes the driven turntable 53 to rotate together, thus achieving linkage.

[0053] To reduce the rotational speed of the drive disc 51 and make the spraying more even, such as Figure 5As shown, the linkage mechanism 5 also includes a limiting mechanism 55, which includes a support 551, a limiting ring 552, and a limiting block 553. The support 551 is fixedly mounted on the frame 1, providing overall support. The limiting ring 552 is fixedly mounted on the top side of the support 551, and the abutment 521 abuts against the inner wall of the limiting ring 552. The limiting ring 552 limits the movement of the abutment 521, allowing it to move only within the limiting ring 552. The limiting block 553 is fixedly mounted on the inner wall of the limiting ring 552, and the abutment 521 can abut against the limiting block 553. Since the limiting block 553 is fixed, when the abutment 521... When the abutment 521 abuts against the limiting block 553, the abutment rod 521 will retract inward due to the obstruction of the limiting block 553. After the abutment rod 521 passes the limiting block 553, it will reset under the action of the spring 525 and continue to move. At this time, the spray pipe 42 is stationary until the abutment rod 521 abuts against the next abutment block 54, and then continues to drive the driven turntable 53 to rotate. At this time, the spray pipe 42 is in a rotating state. Therefore, there are at least two abutment blocks 54 on the inner wall of the driven turntable 53, and they are evenly distributed. The more abutment blocks 54 there are, the shorter the interval time of the spray pipe 42; the fewer abutment blocks 54 there are, the longer the interval time of the spray pipe 42. It can be adjusted according to actual needs.

[0054] To ensure that the stop bar 521 can smoothly bypass the limit block 553, such as Figure 5 As shown, the connection between the side of the limiting block 553 away from the limiting ring 552 and the limiting ring 552 is arc-shaped, which reduces the friction between the limiting block 553 and the abutment 521. Furthermore, the outer diameter of the abutment 54 is less than or equal to the outer diameter of the limiting block 553, so as to prevent the limiting block 553 from being affected by the abutment 54 when blocking the abutment 521.

[0055] To prevent the driven turntable 53 from affecting the intermittent rotation of the spray pipe 42 due to excessive rotation amplitude caused by inertia, the limiting block 553 can abut against the abutment block 54. When the limiting block 553 abuts against the abutment block 54, the friction between the two is used to slow down the abutment block 54, preventing the driven turntable 53 from continuing to rotate due to inertia and causing the abutment block 54 to contact the abutment rod 521 again, thereby improving the stability of the intermittent rotation of the spray pipe 42.

[0056] The support mechanism 6 is used to support the hopper 2 and ensure the stability of the rotating shaft 31 and the water delivery pipe 41 during rotation. The support mechanism 6 includes a connecting bearing 61 and a support rod 62. The connecting bearing 61 is sleeved on the top of the water delivery pipe 41, and the inner ring of the connecting bearing 61 is fixedly connected to the water delivery pipe 41. One end of the support rod 62 is fixedly mounted on the outer ring of the connecting bearing 61, and the other end is fixedly mounted on the hopper 2. The support rod 62 supports the hopper 2 to prevent deformation of the hopper 2, and at the same time fixes the connecting bearing 61. The connecting bearing 61 is used to position the rotating shaft 31 and the water delivery pipe 41.

[0057] To improve the support effect of the support mechanism 6, multiple support rods 62 are provided on the connecting bearing 61, and the multiple support rods 62 are evenly distributed around the center line of the connecting bearing 61, increasing the distribution range of the support rods 62 and making the whole structure more robust and stable.

[0058] The method of using the rice seed coating device of this utility model is as follows:

[0059] In use, first close the discharge gate 201, then pour the seeds into the hopper 2, and then pour the coating agent into the agent tank 43. Start the device, and the drive motor 33 drives the rotating shaft 31 to rotate via the belt. At the same time, the rotating shaft 31 drives the driven turntable 53 on the water supply pipe 41 to rotate via the drive turntable 51 and the transmission mechanism 52. The rotation of the water supply pipe 41 drives the spray pipe 42 to rotate, and under the limiting action of the limit block 553, it achieves intermittent rotation. The pressure pump 44 delivers the coating agent in the agent tank 43 to the spray pipe 42 through the water supply pipe 41. The coating agent is sprayed into the hopper 2 by the spray pipe 42. The rotation of the auger 32 makes the coating agent and seeds fully mixed, completing the seed coating process. After the coating is completed, open the discharge gate 201 and pour out the seeds.

[0060] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
