Description

Technical Field

[0001] This utility model relates to the field of seed scattering machine technology, and in particular to a seed scattering machine for rice planting. Background Technology

[0002] A seed scatterer is a device used in rice cultivation to scatter seeds. When using a seed scatterer, a drone carries the storage tank into the air. When the scatterer reaches the appropriate position in the air, the solenoid valve is opened, allowing the seeds to come out through the discharge port, thus effectively scattering the seeds.

[0003] The inventors discovered in their daily work that the seed scattering machine still has at least the following problems: When using the seed scattering machine, the storage tank is carried into the air by a drone. When the scattering machine flies to the appropriate position in the air, the solenoid valve opens, allowing the seeds to come out through the discharge port. This can effectively scatter the seeds. However, in actual use, because the storage tank is located at the bottom of the drone, it is quite troublesome to replace the storage tank when needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seed scattering machine for rice cultivation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seed scattering machine for rice planting, comprising a drone, a storage tank at the bottom of the drone, an electromagnetic valve at the surface of the discharge port at the bottom of the storage tank, a limiting device at the bottom of the drone, the limiting device comprising a rectangular frame, the rectangular frame being fixedly connected to the top of the storage tank, the rectangular frame being slidably fitted onto the surface of the bottom of the drone, and a fixing frame being fixedly connected to the surface of the bottom of the drone, the fixing frame being disposed at the top of the rectangular frame.

[0006] The effect achieved by the above components is that when using the limiting device, the rectangular frame can be manually placed on the bottom of the drone, and the rectangular frame can be separated from the drone by reversing the operation, which facilitates the maintenance of the storage tank.

[0007] Preferably, a fixing groove is formed on the surface of the bottom of the drone, and a rubber frame is provided on the inner wall of the fixing groove, and the rubber frame and the inner wall of the rectangular frame are fixedly connected.

[0008] The effect achieved by the above components is that when the rectangular frame is fitted onto the bottom surface of the drone, the rubber frame is squeezed inside the fixing groove, which can restrict the rectangular frame to the bottom surface of the drone.

[0009] Preferably, positioning frames are fixedly connected to both sides of the fixed frame, and a U-shaped plate is slidably fitted onto one side of the rectangular frame, with the two ends of the U-shaped plate slidably connected to the inner wall of the positioning frame respectively.

[0010] The effect achieved by the above components is to fit the U-shaped plate onto one side of the rectangular frame, and then slide the U-shaped plate into the inside of the positioning frame, thus confining the U-shaped plate to the surface of the rectangular frame.

[0011] Preferably, a rubber cone block is fixedly connected to one end of the U-shaped plate that passes through the positioning frame, and the rubber cone block is located on the side of the rectangular frame away from the U-shaped plate.

[0012] The effect achieved by the above components is that after the U-shaped plate passes through the positioning frame, the rubber cone block then passes through the positioning frame, thus confining the U-shaped plate inside the positioning frame.

[0013] Preferably, a first damping rod is fixedly connected to one side of the rectangular frame, the end of the first damping rod away from the rectangular frame is fixedly connected to one side of the inner wall of the U-shaped plate, a first spring is sleeved on the surface of the first damping rod, one end of the first spring is fixedly connected to one side of the rectangular frame, the end of the first spring near the U-shaped plate is fixedly connected to one side of the inner wall of the U-shaped plate, and a groove is provided on one side of the drone.

[0014] The effect achieved by the above components is that the U-shaped plate is pulled towards the rectangular frame by the first spring, thus restricting the U-shaped plate to the surface of the rectangular frame.

[0015] Preferably, an L-shaped plate is provided on the side of the U-shaped plate away from the rectangular frame, and the end of the L-shaped plate away from the U-shaped plate is provided on the top of the fixed frame. The end of the L-shaped plate away from the U-shaped plate is slidably connected to the inner wall of the groove.

[0016] The effect achieved by the above components is that one end of the L-shaped plate is slid into the inside of the groove, which can restrict the fixing frame to the top of the rectangular frame.

[0017] Preferably, a second damping rod is fixedly connected to one side of the U-shaped plate, the end of the second damping rod away from the U-shaped plate is fixedly connected to one side of the L-shaped plate, a second spring is sleeved on the surface of the second damping rod, one end of the second spring is fixedly connected to one side of the U-shaped plate, and the end of the second spring near the L-shaped plate is fixedly connected to one side of the L-shaped plate.

[0018] The effect achieved by the above components is that the L-shaped plate is pulled closer to the U-shaped plate by the second spring, thereby making the L-shaped plate fit tightly against one side of the U-shaped plate.

[0019] Preferably, a rubber rod is fixedly connected to the bottom of the inner wall of the groove, and the rubber rod is slidably inserted through the bottom of the L-shaped plate located on the inner wall of the groove.

[0020] The effect achieved by the above components is that by passing the rubber rod through the bottom of one end of the L-shaped plate, the L-shaped plate can be restricted to the top of the fixed frame.

[0021] In this invention, by setting a limiting device, when using the limiting device, the rectangular frame is manually placed on the bottom of the drone, and the rectangular frame and the drone can be separated by reversing the operation, which facilitates the maintenance of the storage tank.

Detailed Implementation

[0027] Example 1, such as Figure 1-4 As shown, a seed scattering machine for rice planting has a storage tank 2 at the bottom of a drone 1. A solenoid valve 3 is installed on the surface of the discharge port at the bottom of the storage tank 2. A limit device 4 is installed at the bottom of the drone 1. When using the seed scattering machine, the drone 1 carries the storage tank 2 into the air. When the scattering machine flies to a suitable position in the air, the solenoid valve 3 is opened, allowing the seeds to come out through the discharge port. This can effectively scatter the seeds.

[0028] Reference Figures 2 to 4The limiting device 4 includes a rectangular frame 401, which is fixedly connected to the top of the storage tank 2. The rectangular frame 401 is slidably fitted onto the bottom surface of the drone 1. A fixing frame 402 is fixedly connected to the bottom surface of the drone 1, and the fixing frame 402 is located on top of the rectangular frame 401. When using the limiting device 4, the rectangular frame 401 is manually fitted onto the bottom of the drone 1. The reverse operation can separate the rectangular frame 401 from the drone 1, which facilitates maintenance of the storage tank 2. A fixing groove 403 is provided on the bottom surface of the drone 1, and a rubber frame 404 is provided on the inner wall of the fixing groove 403. The rubber frame 404 is fixedly connected to the inner wall of the rectangular frame 401. When the rectangular frame 401 is fitted onto the bottom surface of the drone 1, the rubber frame 404... 4 is squeezed inside the fixing groove 403, thus restricting the rectangular frame 401 to the surface of the bottom of the drone 1. Positioning frames 406 are fixedly connected to both sides of the fixing frame 402. A U-shaped plate 405 is slidably fitted onto one side of the rectangular frame 401. Both ends of the U-shaped plate 405 are slidably connected to the inner wall of the positioning frame 406. The U-shaped plate 405 is fitted onto one side of the rectangular frame 401, and then slid into the positioning frame 406, thus restricting the U-shaped plate 405 to the surface of the rectangular frame 401. A rubber cone block 407 is fixedly connected to one end of the U-shaped plate 405 that passes through the positioning frame 406. The rubber cone block 407 is located on the side of the rectangular frame 401 away from the U-shaped plate 405. The U-shaped plate 405 is then slid into the positioning frame 406. After step 6, the rubber cone block 407 is then passed through the positioning frame 406, thus confining the U-shaped plate 405 inside the positioning frame 406. A first damping rod 408 is fixedly connected to one side of the rectangular frame 401. The end of the first damping rod 408 away from the rectangular frame 401 is fixedly connected to one side of the inner wall of the U-shaped plate 405. A first spring 409 is sleeved on the surface of the first damping rod 408. One end of the first spring 409 is fixedly connected to one side of the rectangular frame 401, and the end of the first spring 409 near the U-shaped plate 405 is fixedly connected to one side of the inner wall of the U-shaped plate 405. A groove 413 is provided on one side of the drone 1. By pulling the U-shaped plate 405 towards the rectangular frame 401 through the first spring 409, the U-shaped plate 405 can be confined. On the surface of the rectangular frame 401, an L-shaped plate 412 is provided on the side of the U-shaped plate 405 away from the rectangular frame 401. The end of the L-shaped plate 412 away from the U-shaped plate 405 is located at the top of the fixed frame 402. The end of the L-shaped plate 412 away from the U-shaped plate 405 is slidably connected to the inner wall of the groove 413. By sliding one end of the L-shaped plate 412 into the inside of the groove 413, the fixed frame 402 can be restricted to the top of the rectangular frame 401. A second damping rod 410 is fixedly connected to one side of the U-shaped plate 405. The end of the second damping rod 410 away from the U-shaped plate 405 is fixedly connected to one side of the L-shaped plate 412. A second spring 411 is sleeved on the surface of the second damping rod 410. One end of the second spring 411 is fixedly connected to one side of the U-shaped plate 405.The second spring 411 is fixedly connected to one side of the L-shaped plate 412 near one end. The second spring 411 pulls the L-shaped plate 412 towards the U-shaped plate 405, causing the L-shaped plate 412 to fit tightly against one side of the U-shaped plate 405. A rubber rod 414 is fixedly connected to the bottom of the inner wall of the groove 413. The rubber rod 414 is slidably inserted through the bottom of the portion of the L-shaped plate 412 located on the inner wall of the groove 413. By passing the rubber rod 414 through the bottom of one end of the L-shaped plate 412, the L-shaped plate 412 is confined to the top of the fixing frame 402.

[0029] Working principle: When using the seed disperser, the drone 1 carries the storage tank 2 into the air. When the disperser reaches the appropriate position in the air, the solenoid valve 3 is opened, allowing the seeds to exit through the discharge port, thus effectively dispersing the seeds. When using the limiting device 4, the rectangular frame 401 is manually fitted onto the bottom of the drone 1. When the rectangular frame 401 is fitted onto the bottom surface of the drone 1, the rubber frame 404 is pressed into the fixing groove 403, thus restricting the rectangular frame 401 to the bottom surface of the drone 1. The U-shaped plate 405 is fitted onto one side of the rectangular frame 401, and the first spring 409 pulls the U-shaped plate 405 towards the rectangular frame 401, thus restricting the U-shaped plate 405 to the surface of the rectangular frame 401, and then sliding the U-shaped plate 405 into the positioning frame. Inside 406, after passing the U-shaped plate 405 through the positioning frame 406, the rubber cone block 407 passes through the positioning frame 406, thus confining the U-shaped plate 405 inside the positioning frame 406. This confines the U-shaped plate 405 to the surface of the rectangular frame 401. The L-shaped plate 412 is pulled towards the U-shaped plate 405 by the second spring 411, thus making the L-shaped plate 412 fit tightly against one side of the U-shaped plate 405. One end of the L-shaped plate 412 is slid into the groove 413, and the rubber rod 414 passes through the bottom of one end of the L-shaped plate 412, thus confining the L-shaped plate 412 to the top of the fixing frame 402. This confins the fixing frame 402 to the top of the rectangular frame 401. The reverse operation can separate the rectangular frame 401 from the drone 1, which facilitates the maintenance of the storage tank 2.

[0030] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
