Description

Technical Field

[0001] This utility model relates to the field of agricultural planting tools, and in particular to a precision seeding device for wheat plot experiments. Background Technology

[0002] With the rapid development of precision agriculture technology, many crops have gradually achieved precision seeding. However, wheat, as a crucial grain crop globally, still faces insufficient exploration and research in precision seeding technology. Achieving precise monitoring of wheat seeding rates can not only scientifically determine the optimal seeding rate, providing a solid basis for increasing yields and income, but also effectively save seeding costs, further enhancing the overall economic benefits of agricultural production.

[0003] For example, the wheat sowing device for agricultural planting disclosed in the utility model with authorization announcement number CN216795698U, "in use, the sowing device is installed at the rear of the tractor through the connector on the connecting frame. Then, wheat seeds are poured into three feed boxes. When sowing is needed, the internal threaded tube is rotated by the torsion wheel. Under the action of the thread, the internal threaded tube drives the connecting strip to move through the screw. The connecting strip then drives the three blocking plates to move until the fixing frame is opened. At this time, the wheat seeds in the feed box will fall onto the dispersing wheel through the outlet. When the tractor drives the sowing device to move, the roller will drive the rotating rod to rotate. The rotating rod will drive the first pulley to rotate. The first pulley drives the second pulley to rotate through the pull belt. The second pulley drives the driving rod to rotate. The driving rod then drives..." Three dispersing wheels rotate, and the wheat seeds falling onto them are orderly deposited into the receiving hopper by the wheels. Simultaneously, the sowing device, as it moves, plows the land with a plowshare. The wheat seeds then fall through the outlet on the receiving hopper into the plowed furrows. As the sowing device moves further, the furrows are smoothed by a trowel, allowing for burying the seeds, thus completing the sowing process. However, because the height of the furrow opener is fixed and cannot be adjusted, the furrow depth cannot be flexibly adjusted according to actual needs. Furthermore, the position of the sower is also fixed and cannot be adjusted, making it difficult to adapt the sowing spacing to different planting requirements. These limitations significantly reduce the adaptability of the device, making it rather limited when facing diverse planting scenarios. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a precision seeding device for wheat plot experiments, comprising a seeding vehicle, a fixed seeder installed through the surface of the seeding vehicle, a lifting furrow opener slidably disposed at the front end of the seeding vehicle, two sliding openings formed on the surface of the seeding vehicle, a drive mechanism fixedly installed on the surface of the seeding vehicle, and two moving ends of the drive mechanism fixedly connected to moving arms, the sliding ends of the moving arms slidably engaging with the sliding openings, a moving seeder installed on the surface of the sliding ends of the moving arms, a furrow opener fixedly connected to the sliding portion of the moving arms, a lifting mechanism fixedly connected to the surface of the seeding vehicle, the lower end of the lifting mechanism fixedly connected to the sliding portion of the moving arms, and the lower end of the lifting mechanism fixedly connected to the lifting furrow opener.

[0005] As an improvement to the above technical solution, the movable arm includes a sliding frame, a movable plate, a vertical plate, a first slide rail, and a first slider. The sliding frame is slidably engaged inside the sliding opening. The movable plate is fixedly connected to the upper end of the sliding frame. The movable plate is fixedly connected to the moving end of the drive mechanism. The vertical plate is fixedly connected to one end of the movable plate. The first slide rail is fixedly connected to the surface of the vertical plate. The first slider is slidably connected inside the first slide rail. The lower end of the first slider is fixedly connected to a first furrow opener. The side end of the first slider is fixedly connected to the lower end of the lifting mechanism. The movable seeder passes through the sliding frame and is fixedly connected to the sliding frame.

[0006] As an improvement to the above technical solution, a reinforcing plate is fixedly provided at the connection between the movable plate and the vertical plate.

[0007] As an improvement to the above technical solution, the lifting mechanism includes an electric push rod, a connecting rod, and a telescopic rod. The electric push rod is installed at the front end of the seeding vehicle through a connecting frame. The lower end of the electric push rod is fixedly connected to the connecting rod. Telescopic rods are fixedly connected to both sides of the connecting rod. The telescopic end of the telescopic rod is fixedly connected to a slider. One end of the connecting rod is fixedly connected to the lifting furrow opener.

[0008] As an improvement to the above technical solution, the lifting furrow opener includes a sliding rod and a second furrow opener. The sliding rod is slidably connected to the seeding vehicle, the lower end of the sliding rod is fixedly connected to the second furrow opener, and one end of the sliding rod is fixedly connected to a connecting rod.

[0009] As an improvement to the above technical solution, the driving mechanism includes a second slide rail, a second slider, a motor, and a bidirectional lead screw. The second slide rail and the motor are mounted on the surface of the seeding vehicle. Two second sliders are slidably connected inside the second slide rail. The output end of the motor is fixedly connected to the bidirectional lead screw. The bidirectional lead screw passes through the second slider and is threadedly connected to the second slider.

[0010] The beneficial effects of this utility model are: The drive mechanism moves the mobile arm, changing the distance between the mobile seeder and the fixed seeder. This allows for precise adjustment of the sowing spacing based on different experimental needs and planting plans, meeting diverse requirements for wheat plot trials and improving the accuracy and scientific rigor of the experiments. The lifting mechanism simultaneously raises and lowers the lifting furrow opener and furrow opener one. Operators can flexibly adjust the furrow depth based on soil texture, wheat variety, and other factors, creating a suitable germination and growth environment for wheat seeds. This helps improve seed germination rate and seedling survival rate. When the mobile arm moves, furrow opener one is always aligned with the mobile seeder, ensuring a precise match between the furrow position and the sowing position. This avoids deviations between the furrow and sowing positions affecting seed germination and growth, ensuring uniform and consistent wheat growth. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: a precision seeding device for wheat plot experiments, including a seeding vehicle 1, a fixed seeder 2 installed through the surface of the seeding vehicle 1, a lifting furrow opener 3 slidably arranged at the front end of the seeding vehicle 1, two sliding openings 5 ​​opened on the surface of the seeding vehicle 1, a drive mechanism 8 fixedly installed on the surface of the seeding vehicle 1, a moving arm 4 fixedly connected to each of the two moving ends of the drive mechanism 8, the sliding end of the moving arm 4 slidably engaging with the sliding opening 5, a moving seeder 9 installed on the surface of the sliding end of the moving arm 4, a furrow opener 6 fixedly connected to the sliding part of the moving arm 4, a lifting mechanism 7 fixedly connected to the surface of the seeding vehicle 1, the lower end of the lifting mechanism 7 fixedly connected to the sliding part of the moving arm 4, and the lower end of the lifting mechanism 7 fixedly connected to the lifting furrow opener 3.

[0015] In this implementation scheme, the user activates the drive mechanism 8, causing the two moving ends of the drive mechanism 8 to move, which in turn drives the two moving arms 4 to move closer or further apart. As the two moving arms 4 move, the two moving seeders 9 move, causing the distance between the two moving seeders 9 and the fixed seeder 2 to change, thereby adjusting the seeding spacing. At the same time, the moving arms 4 drive the furrow openers 6 to move, ensuring that the two furrow openers 6 are always aligned with the moving seeders 9. Then, the user activates the lifting mechanism 7, causing the lower end of the lifting mechanism 7 to rise or fall, which in turn drives the lifting furrow opener 3 and the two furrow openers 6 to rise or fall simultaneously, thereby adjusting the furrow depth. This allows the precision seeding device for wheat plot trials to flexibly adjust the seeding spacing and furrow depth according to the actual situation, providing a strong guarantee for efficient and precise wheat planting.

[0016] like Figure 3 and Figure 4 As shown, the movable arm 4 includes a sliding frame 41, a movable plate 42, a vertical plate 43, a slide rail 44, and a slider 45. The sliding frame 41 is slidably engaged inside the sliding opening 5. The upper end of the sliding frame 41 is fixedly connected to the movable plate 42. The movable plate 42 is fixedly connected to the moving end of the drive mechanism 8. One end of the movable plate 42 is fixedly connected to the vertical plate 43. The surface of the vertical plate 43 is fixedly connected to the slide rail 44. The slider 45 is slidably connected inside the slide rail 44. The lower end of the slider 45 is fixedly connected to the furrow opener 6. The side end of the slider 45 is fixedly connected to the lower end of the lifting mechanism 7. The movable seeder 9 passes through the sliding frame 41 and is fixedly connected to the sliding frame 41.

[0017] In this embodiment, the user activates the drive mechanism 8, which moves the two movable plates 42 and the two vertical plates 43 simultaneously. This causes the sliding frame 41 to slide inside the sliding opening 5, thereby adjusting the distance between the two movable seeders 9 and the fixed seeder 2. At the same time, it moves the two furrow openers 6, ensuring that the furrow openers 6 remain flush with the movable seeders 9. Since the slider 45 can slide up and down inside the slide rail 44, it works in conjunction with the lifting mechanism 7 to move the furrow openers 6 up and down.

[0018] like Figure 4 As shown, a reinforcing plate 46 is fixedly installed at the connection between the movable plate 42 and the vertical plate 43.

[0019] In this embodiment, by fixing a reinforcing plate 46 at the connection between the movable plate 42 and the vertical plate 43, the connection strength between the movable plate 42 and the vertical plate 43 can be improved.

[0020] like Figure 4 As shown, the lifting mechanism 7 includes an electric push rod 71, a connecting rod 72, and a telescopic rod 73. The electric push rod 71 is installed at the front end of the seeding vehicle 1 through a connecting frame. The lower end of the electric push rod 71 is fixedly connected to the connecting rod 72. Telescopic rods 73 are fixedly connected to both sides of the connecting rod 72. The telescopic end of the telescopic rod 73 is fixedly connected to the slider 45. One end of the connecting rod 72 is fixedly connected to the lifting furrow opener 3.

[0021] In this embodiment, the user activates the electric push rod 71, causing the telescopic end of the electric push rod 71 to drive the connecting rod 72 to rise and fall. As the connecting rod 72 rises and falls, it can drive the lifting furrow opener 3 to slide up and down on the surface of the seeding vehicle 1. At the same time, the connecting rod 72 can also drive the two furrow openers 6 to move up and down on the surface of the vertical plate 43 through the telescopic rods 73 on both sides. Therefore, by activating the electric push rod 71, the user can simultaneously drive the two furrow openers 6 and one lifting furrow opener 3 to rise and fall at the same time to adjust the furrowing depth. Since the telescopic rod 73 has telescopic characteristics, it does not affect the adjustment of the distance between the two furrow openers 6.

[0022] like Figure 4 As shown, the lifting furrow opener 3 includes a sliding rod 31 and a furrow opener 32. The sliding rod 31 is slidably connected to the seeding vehicle 1, the lower end of the sliding rod 31 is fixedly connected to the furrow opener 32, and one end of the sliding rod 31 is fixedly connected to the connecting rod 72.

[0023] In this embodiment, when the electric push rod 71 drives the connecting rod 72 to rise and fall, it will cause the sliding rod 31 to slide up and down on the surface of the seeding vehicle 1, thereby adjusting the height of the furrow opener 32.

[0024] like Figure 3 and Figure 4 As shown, the drive mechanism 8 includes a slide rail 81, a slider 82, a motor 83, and a double-acting lead screw 84. The slide rail 81 and the motor 83 are mounted on the surface of the seeding vehicle 1. Two sliders 82 are slidably connected inside the slide rail 81. The output end of the motor 83 is fixedly connected to the double-acting lead screw 84. The double-acting lead screw 84 passes through the sliders 82 and is threadedly connected to the sliders 82.

[0025] In this embodiment, the user starts the motor 83, which drives the bidirectional lead screw 84 to rotate, thereby causing the two sliders 82 to slide inside the slide rail 81. Since the two sliders 82 slide inside the slide rail 81, the two moving plates 42 can be moved at the upper end of the seeding vehicle 1.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
