Its large size also makes it difficult to operate in small plots or areas with complex terrain. Second, most existing seeders are designed for large-scale farmland and lack flexibility in adjusting parameters such as row spacing and seeding rate, failing to meet the diverse sowing requirements of different grain crops and planting needs. Third, some mechanical sowing equipment is complex to operate, requiring professional operators for operation and maintenance, increasing the difficulty and learning cost for farmers.

[0004] Therefore, this utility model designs a portable grain crop sowing and fertilization device to solve the above-mentioned technical problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 6 As shown, this embodiment provides a portable grain crop sowing and fertilization device, including:

[0033] The frame 7 is equipped with a height-adjustable handle 11;

[0034] The walking mechanism includes a drive wheel 1 and a soil covering wheel 6, with the drive wheel 1 located at the front end of the frame 7 and the soil covering wheel 6 located at the rear end of the frame 7.

[0035] The seeding mechanism includes a fertilization component and a seeding component arranged on the frame 7 in the front-to-back direction, and the distance between the fertilization component and the seeding component is adjustable;

[0036] The adjustment mechanism includes a drive rail 13 mounted on the frame 7. The fertilization component and the sowing component pass through the drive rail 13 respectively. A slider 12 for adjusting the interval between the seeds and fertilizer is slidably connected inside the drive rail 13. The slider 12 is connected to the drive wheel 1 for transmission.

[0037] This utility model discloses a portable grain crop sowing and fertilization device, comprising four parts: a frame 7, a walking mechanism, a sowing mechanism, and an adjustment mechanism. It addresses the problems of high cost, poor flexibility, and complex operation found in existing sowing equipment, achieving efficient, precise, and low-cost sowing of grain crops. The frame 7 is equipped with a height-adjustable handle 11, allowing users to adjust the handle 11 according to their height and operating habits, thus improving operational comfort and equipment adaptability. The walking mechanism, as the device's moving component, makes its movement more flexible. Simultaneously, the drive wheel 1 provides the sowing power for fertilizer and seeds; sowing can be performed simply by pushing the handle 11, requiring no professional operating skills and reducing the difficulty and learning cost for growers. The walking mechanism includes corresponding drive wheels 1 and covering wheels 6. The drive wheels 1 are located at the front end of the frame 7 to propel the entire device forward, while the covering wheels 6 are located at the rear end of the frame 7 for adjusting the soil after sowing. The soil is covered on the seeds, completing sowing and covering in one step, reducing workload. The sowing mechanism consists of a fertilization component and a sowing component set along the front-to-back direction on the frame 7. The distance between the fertilization component and the sowing component is adjustable, allowing the spacing between fertilizer and seeds to be adjusted according to the planting needs of the crop, thereby optimizing the planting effect, meeting the absorption of fertilizer by different seeds, and improving the germination probability of seeds. The adjustment mechanism includes a drive rail 13 set on the frame 7, through which the fertilization component and the sowing component pass. The slider 12 slides on the drive rail 13 powered by the drive wheel 1. The falling interval of fertilizer and seeds by the slider 12 achieves precise adjustment of the seed sowing spacing, meeting the seed spacing requirements of different crops. The adjustment of the planting interval and the seed-fertilizer interval can control the sowing amount, reduce seed waste, meet the diversified sowing requirements of different varieties of grain crops and different planting needs, and is suitable for various terrains and farmlands of different sizes. This utility model has a simple structure, is easy to use, flexible in operation, lower cost, is easy to carry and store, and is convenient to move and store in the field. It can meet the diverse sowing requirements of different varieties of grain crops and different planting needs, and is suitable for small-scale growers.

[0038] In a further optimized design, a flywheel 3 is rotatably connected to the frame 7. The flywheel 3 is connected to the drive wheel 1 via a transmission belt 2, and the slider 12 is connected to the flywheel 3 via a drive arm 10. The flywheel 3 is rotatably connected to the frame 7 and connected to the drive wheel 1 via the transmission belt 2, achieving synchronous rotation between the flywheel 3 and the drive wheel 1. The slider 12 is connected to the flywheel 3 via the drive arm 10, allowing the flywheel 3 to drive the slider 12 to slide on the drive track 13, thereby adjusting the falling interval of seeds and fertilizers, and thus achieving adjustable sowing spacing to suit the planting needs of different types of crops.

[0039] In one embodiment of this utility model, the drive wheel 1, the soil covering wheel 6, and the flywheel 3 are all mounted on the frame 7 via bearings, which facilitates flexible rotation.

[0040] To further optimize the design, multiple adjustment holes 20 are provided on the radius of the flywheel 3, and the end of the drive arm 10 away from the slider 12 is connected to any one of the adjustment holes 20. The multiple adjustment holes 20 along a single radius of the flywheel 3 allow the end of the drive arm 10 to be connected to different adjustment holes 20. Different adjustment holes 20 correspond to different linear velocities, thereby changing the moving speed of the slider 12 driven by the drive arm 10, adjusting the falling interval of seeds and fertilizer, and thus achieving variations in plant spacing. This allows the device to be changed and adjusted according to different crops, increasing the flexibility of sowing.

[0041] The design is further optimized. The fertilization component includes a fertilizer hopper 9 and a fertilizer outlet 4. The fertilizer hopper 9 is fixedly connected to the top of the drive track 13, and the fertilizer outlet 4 is fixedly connected to the bottom of the drive track 13. The fertilizer hopper 9 and the fertilizer outlet 4 are staggered. The design of the fertilizer hopper 9 and the fertilizer outlet 4 allows fertilizer to be conveniently stored in the device and discharged when needed. The staggered arrangement of the fertilizer hopper 9 and the fertilizer outlet 4 at the upper and lower ends of the drive track 13 avoids direct flow of fertilizer. Fertilizer is dispensed by sliding the slider 12. When the speed of the slider 12 driven by the flywheel 3 changes, the fertilizer dispensing interval can be adjusted.

[0042] The design is further optimized sowing components, including a seed hopper 8 and a seed outlet 5. The seed hopper 8 is fixedly connected to the top of the drive track 13, and the seed outlet 5 is fixedly connected to the bottom of the drive track 13. The seed hopper 8 and the seed outlet 5 are staggered. The design of the seed hopper 8 and the seed outlet 5 allows seeds to be conveniently stored in the device and discharged when needed. The staggered arrangement of the seed hopper 8 and the seed outlet 5 at the upper and lower ends of the drive track 13 also avoids direct seed discharge. Seeds are dispensed by sliding the slider 12. When the speed of the slider 12 driven by the flywheel 3 changes, the seed dispensing spacing can be adjusted to achieve plant spacing adjustment.

[0043] Further optimization involves a first transfer hole 18 and a second transfer hole 19 running longitudinally through the slider 12. When the slider 12 slides, the two ends of the first transfer hole 18 connect sequentially to the fertilizer hopper 9 and the fertilizer outlet 4, while the two ends of the second transfer hole 19 connect sequentially to the seed hopper 8 and the seed outlet 5. The first transfer hole 18 and the second transfer hole 19 on the slider 12 are used to connect the fertilizer hopper 9 to the fertilizer outlet 4 and the seed hopper 8 to the seed outlet 5, respectively. In actual operation, the top of the first transfer hole 18 on the slider 12 first aligns with the fertilizer hopper 9, and the fertilizer falls into the first transfer hole 18. Then, the slider 12 moves, causing the fertilizer in the first transfer hole 18 to move until the bottom of the slider 12 aligns with the fertilizer outlet 4, and the fertilizer in the first transfer hole 18 falls into the fertilizer outlet 4. Fertilization is completed in the soil. During this process, when the first transfer hole 18 is aligned with the fertilizer hopper 9, the top of the second transfer hole 19 is aligned with the bottom of the seed hopper 8, and the seeds fall into the second transfer hole 19. The slider 12 slides through the second transfer hole 19 to move the seeds horizontally. When the bottom of the first transfer hole 18 is aligned with the fertilizer outlet 4, the bottom of the second transfer hole 19 is aligned with the seed outlet 5. The seeds in the second transfer hole 19 enter the seed outlet 5 and fall into the soil to complete the sowing, thus simultaneously completing the application of seeds and fertilizer.

[0044] In one embodiment of this utility model, the top end of the drive track 13 is provided with a first feed hole 14 and a second feed hole 15. The bottom end of the fertilizer hopper 9 is aligned with the first feed hole 14, and the bottom end of the seed hopper 8 is aligned with the second feed hole 15, so that fertilizer and seeds can be easily transferred to the slider 12.

[0045] In one embodiment of this utility model, the bottom end of the drive track 13 is provided with a first discharge hole 16 and a second discharge hole 17. The top end of the fertilizer outlet 4 is aligned with the first discharge hole 16, and the top end of the seed outlet 5 is aligned with the second discharge hole 17, so that the fertilizer and seeds transferred in the slider 12 can be discharged to complete the sowing and fertilization.

[0046] In one embodiment of this utility model, when both the upper and lower end faces of the slider 12 are flat, the falling channel of fertilizer and seeds can be blocked when the corresponding holes are misaligned, thereby achieving intermittent planting.

[0047] In a further optimized design, clearance holes 21, corresponding to those of the slider 12, are provided at both ends of the drive track 13. When the slider 12 slides, its end passes through the clearance holes 21. The clearance holes 21 at both ends of the drive track 13 allow the end of the slider 12 to pass through during sliding, thereby avoiding interference between the slider 12 and the drive track 13. This reduces the length of the drive track 13, thereby reducing the material used in the equipment and lowering costs. It also reduces the overall weight of the equipment, making it easier to carry and store, and facilitating its movement and storage in the field.

[0048] In a further optimized design, the drive arm 10 includes a driven rod 23 rotatably connected to the middle of the slider 12. An active rod 22 is hinged to the end of the driven rod 23 furthest from the slider 12. The active rod 22 is connected to any adjustment hole 20 via a positioning rod 25. The drive arm 10, composed of the driven rod 23 and the active rod 22 hinged at its ends, transmits the linear velocity of the flywheel 3's rotation to the reciprocating translation of the slider 12, ensuring that the slider 12 can slide according to a predetermined speed and stroke. One end of the positioning rod 25 is connected to the adjustment hole 20 via a thread or other means, while the end of the driven rod 23 is rotatably connected to the positioning rod 25, facilitating the transmission of power from the flywheel 3 to the slider 12.

[0049] In one embodiment of this utility model, the design of the frame 7 needs to avoid interference between the positioning rod 25 and the drive arm 10 and the frame 7 when the flywheel 3 rotates. For example, the frame 7 is provided with a bending structure at the position where it interferes with the positioning rod 25 and the drive arm 10, so that the position through which the positioning rod 25 and the drive arm 10 pass is cleared. Other methods that can achieve the same function as this application are also within the protection scope of this application.

[0050] In a further optimized design, a driving wheel 26 is coaxially mounted on the drive wheel 1, and a driven wheel 27 is coaxially mounted on the flywheel 3. A transmission belt 2 connects the driving wheel 26 and the driven wheel 27. By setting the driving wheel 26 and the driven wheel 27 on the drive wheel 1 and flywheel 3 respectively, and connecting them via the transmission belt 2, synchronous and stable rotation of the drive wheel 1 and flywheel 3 is achieved, improving the overall stability and reliability of the device. Furthermore, no additional power is required; sowing and fertilization can be carried out simply by moving the device.

[0051] The design has been further optimized by installing regulating valves 24 at the outlets of fertilizer hopper 9 and seed hopper 8. These regulating valves 24 allow users to adjust the amount of fertilizer and seeds dispensed as needed, improving the accuracy and flexibility of sowing and meeting the planting needs of different crops.

[0052] Working Principle: During operation, seeds and fertilizer are poured into the seed hopper 8 and fertilizer hopper 9, respectively. The operator holds the handle 11 on the frame 7 and pushes the sowing device forward, causing the drive wheel 1 to roll on the ground. As the drive wheel 1 rotates, it drives the flywheel 3 to rotate synchronously via the transmission belt 2. The flywheel 3, through the drive arm 10, drives the slider 12 to slide on the drive track 13. This causes the first transfer hole 18 on the slider 12 to periodically connect with the fertilizer hopper 9 and fertilizer outlet 4, respectively, for transferring fertilizer. The second transfer hole 19 periodically connects with the seed hopper 8 and seed outlet 5, respectively, for transferring seeds. This allows the seeds and fertilizer to be periodically planted into the soil at set intervals. After the fertilizer and seeds are planted, the soil covering wheel 6 covers the seeds, completing the sowing process. During sowing, the operator can adjust the sowing amount and row spacing according to actual needs using the adjustment mechanism.
