Description

Technical Field

[0001] This invention relates to the field of fertilization devices, specifically a quantitative fertilization device for rice sowing. Background Technology

[0002] Rice is a cereal crop of the genus Oryza. After sowing, rice seedlings are fertilized to ensure their vigorous growth. In order to avoid over-fertilization of rice seedlings in some areas, quantitative fertilization is required.

[0003] However, existing quantitative fertilization devices for rice seedlings after sowing, while capable of quantitative fertilization by controlling the amount of fertilizer discharged from the discharge port, suffer from poor quantitative fertilization results because the movement of agricultural machinery within the paddy field causes water fluctuations, and the applied fertilizer particles float on the water surface and drift with the fluctuations. This leads to insufficient fertilization in some areas and excessive fertilization in others. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a quantitative fertilization device for rice sowing.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a quantitative fertilizer application device for rice sowing, including an outer shell, a feeding pipe fixedly connected to the bottom of the outer shell, a feeding port through which the bottom of the outer shell is opened corresponding to the position of the feeding pipe, and the outer shell is connected to the feeding pipe through the feeding port; A servo motor is fixedly connected to the outer wall of one side of the housing via a fixed frame. The output end of the servo motor passes through the housing and is fixedly connected to a rotating disk. The rotating disk is rotatably connected inside the housing. A stroke groove is provided on the side wall of the rotating disk away from the servo motor. A stroke block is slidably connected inside the stroke groove. A first rotating shaft is rotatably inserted into one end of the stroke block that extends out of the stroke groove. A fertilizer block is rotatably sleeved on the shaft wall of the first rotating shaft. A feed groove is provided through the side wall of the fertilizer block. A discharge groove is provided through the bottom of the feed groove. The bottom of the fertilizer block passes through the discharge port and is inserted into the inside of the discharge pipe. A second groove is provided on the outer wall of the fertilizer block at the end away from the first rotating shaft. A fastening plate is rotatably connected inside the second groove through the second rotating shaft. A matching arc-shaped flip groove is provided on the inner wall of the second groove corresponding to the fastening plate. The arc-shaped flip groove is co-centered with the first rotating shaft. A second groove is provided on the outer wall of the fastening plate. A flip wing plate is rotatably connected to the inner top of the second groove through the third rotating shaft.

[0006] Specifically, a feed pipe is fixedly connected to the top of the outer shell.

[0007] Specifically, the servo motor is electrically connected to an external power supply via a PLC controller.

[0008] Specifically, limit sliders are fixedly connected to the side walls on both sides of the stroke block, and a matching limit groove is provided on the inner wall of the stroke groove corresponding to the position of the limit slider. The limit slider is slidably connected inside the limit groove.

[0009] Specifically, a first spring is fixedly connected to one end of the travel block inside the travel groove, and the other end of the first spring is fixedly connected to the inner wall of the travel groove.

[0010] Specifically, a third groove is formed on the wall of the flip-up wing plate located inside the second groove. A second spring is fixedly connected to the inner wall of the third groove, and the other end of the second spring is fixedly connected to the inner wall of the second groove.

[0011] The beneficial effects of this invention are: This invention discloses a quantitative fertilization device for rice sowing. It features a simple structure and convenient operation. A servo motor drives a rotating disk, which in turn rotates the first rotating shaft on the stroke block, causing the fertilizer block to reciprocate and extend along the feeding port. When the fertilizer block retracts into the outer shell, it quantitatively adds fertilizer into the feeding trough. When the fertilizer block extends out of the outer shell, it discharges the fertilizer from the feeding trough, thus achieving quantitative fertilization. Furthermore, when the fertilizer block extends out of the outer shell, it can insert into the soil inside the paddy field, quantitatively adding fertilizer into the soil and preventing fertilizer particles from floating aimlessly on the water surface, thereby improving the effectiveness of quantitative fertilization.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-10 As shown, the present invention provides a quantitative fertilizer application device for rice sowing, comprising an outer shell 1, a feeding pipe 3 fixedly connected to the bottom of the outer shell 1, and a feeding port 4 penetrating through the bottom of the outer shell 1 corresponding to the position of the feeding pipe 3, and the outer shell 1 communicating with the feeding pipe 3 through the feeding port 4. A servo motor 5 is fixedly connected to the outer wall of one side of the outer shell 1 via a fixed frame. The output end of the servo motor 5 passes through the outer shell 1 and is fixedly connected to a rotating disk 6. The rotating disk 6 is rotatably connected to the inside of the outer shell 1. A stroke groove 7 is provided on the side wall of the rotating disk 6 away from the servo motor 5. A stroke block 8 is slidably connected inside the stroke groove 7. A first rotating shaft 12 is rotatably inserted into one end of the stroke block 8 extending out of the stroke groove 7. A fertilizer block 13 is rotatably sleeved on the shaft wall of the first rotating shaft 12. A feed channel 15 is provided through the side wall of the fertilizer block 13. A discharge channel 14 is provided through the bottom of the feed channel 15. The bottom of the fertilizer block 13 passes through the discharge port 4 and is inserted into the inside of the discharge pipe 3. A second groove 16 is provided on the outer wall of the fertilizer block 13 at the end away from the first rotating shaft 12. The inside of the second groove 16 is rotatably connected to the fastening plate 18 through the second rotating shaft 17. The inner wall of the second groove 16 is provided with a matching arc-shaped flip groove 19 corresponding to the fastening plate 18. The arc-shaped flip groove 19 is set with the same center as the first rotating shaft 12. A second groove 20 is provided on the outer wall of the fastening plate 18. The inner top of the second groove 20 is rotatably connected to the flip wing plate 22 through the third rotating shaft 21.

[0017] The top of the outer shell 1 is fixedly connected to the feed pipe 2, which can effectively transport fertilizer into the interior of the outer shell 1, making it more convenient to add fertilizer to the outer shell 1.

[0018] Servo motor 5 is electrically connected to an external power supply via a PLC controller. The TB6600 PLC controller can effectively control the speed and direction of servo motor 5, ensuring that the device can drive normally.

[0019] Limiting sliders 9 are fixedly connected to the side walls on both sides of the stroke block 8, and a matching limiting groove 10 is provided on the inner wall of the stroke groove 7 corresponding to the position of the limiting slider 9. The limiting slider 9 is slidably connected inside the limiting groove 10. When the limiting slider 9 slides inside the limiting groove 10, it can effectively make the stroke block 8 slide more stably inside the stroke groove 7.

[0020] One end of the stroke block 8 located inside the stroke groove 7 is fixedly connected to a first spring 11, and the other end of the first spring 11 is fixedly connected to the inner wall of the stroke groove 7. The elastic force of the first spring 11 can effectively push the stroke block 8 to slide inside the stroke groove 7.

[0021] The flip-wing plate 22 has a third groove 23 on one side of the plate wall inside the second groove 20. A second spring 24 is fixedly connected to the inner wall of the third groove 23. The other end of the second spring 24 is fixedly connected to the inner wall of the second groove 20. The elastic force of the second spring 24 can push the flip-wing plate 22 hinged inside the second groove 20 to flip outward.

[0022] In the initial state, as shown in the appendix Figure 1 As shown, at this time, the fertilizer block 13 extends out to form the feed pipe 3; In use, the servo motor 5 is started, and the output of the servo motor 5 drives the rotating disk 6 to rotate inside the outer shell 1. When the rotating disk 6 rotates, it can drive the fertilizer block 13, which is rotatably connected to the stroke block 8 via the first rotating shaft 12, to rotate together. However, since the fertilizer block 13 is movably inserted into the inside of the feed pipe 3 and cannot rotate, the rotation of the rotating disk 6 causes the stroke block 8 to slide inside the stroke groove 7, causing the axis of the first rotating shaft 12 to gradually shift closer to the axis of the rotating disk 6, until the first rotating shaft 12 and the rotating disk 6 are coaxial. The fertilizer block 13 moves upward with the movement of the first rotating shaft 12 and retracts towards the inside of the outer shell 1. When the fertilizer block 13 moves upward, the fastening plate 18 hinged inside the first groove 16 and the flipping wing plate 22 hinged inside the second groove 20 on its outer wall can retract into the inside of the first groove 16 and the second groove 20, respectively. The positional relationship between the fertilizer block 13 and the rotating disk 6 is shown in the attached figure. Figure 5 As shown, the rotating disk 6 is currently rotated 90 degrees. As the rotating disk 6 continues to rotate, when it rotates 180 degrees, the stroke block 8, under the elastic force of the first spring 11, causes the first rotating shaft 12 to move towards the inner top of the stroke groove 7. The first rotating shaft 12 then drives the fertilizer block 13 to further retract. The positional relationship between the fertilizer block 13 and the rotating disk 6 at this time is shown in the attached figure. Figure 6 As shown, at this time, the fertilizer inside the outer shell 1 will be added to the inside of the discharge trough 14 along the feed channel 15. The bottom of the discharge trough 14 is closed by two fastening plates 18. At this time, the fertilizer is temporarily stored inside the discharge trough 14. As the rotating disk 6 continues to rotate, when the rotating disk 6 has rotated 270 degrees, the positional relationship between the fertilizer block 13 and the rotating disk 6 is shown in the attached figure. Figure 5 As shown, the flipping wing plate 22 inside the second groove 20 on the fastening plate 18 can be flipped ninety degrees under the elastic force of the second spring 24, and when the fertilizer block 13 continues to extend downward, the bottom of the fertilizer block 13 can be inserted into the soil. As the rotating disk 6 continues to rotate, after the rotating disk 6 completes one revolution, the flipping wing plate 22 on the fertilizer block 13 continues to flip upward under the resistance of the soil, causing the fastening plate 18 to flip around the second rotating shaft 17 as the axis. After the fastening plate 18 flips outward, the end of the fastening plate 18 extending into the feeding trough 14 will separate, so that the fertilizer inside the feeding trough 14 will fall into the soil, thereby preventing the fertilizer particles from floating on the water surface and drifting randomly, which can effectively improve the quantitative fertilization effect.
