[0001] This utility model relates to the field of ecological restoration device technology, and in particular to an adjustable seed reseeder for grassland ecological restoration. Background Technology

[0002] A seed reseeder is an agricultural device used for precise reseeding. Its main function is to reseed areas with missing seedlings, broken rows, or uneven emergence during crop growth, ensuring even crop distribution and improving land utilization and yield. This device is easy to operate, highly efficient, reduces manual reseeding costs, and is suitable for various crop planting and management.

[0003] However, most traditional reseeders are fixed in design and lack adjustable features, limiting their application to a single crop or specific planting pattern. This limitation not only restricts their use but also reduces operational efficiency, making it difficult to meet the diverse and precise sowing needs of modern agriculture. Furthermore, traditional reseeders are difficult to adjust to different row spacings, plant spacings, and soil conditions, increasing manual intervention and operating costs.

[0004] Therefore, it is necessary to design an adjustable seed reseeder for grassland ecological restoration to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional reseeders, such as the lack of adjustable functions, which makes adjustments difficult and increases manual intervention and operating costs, this utility model provides an adjustable seed reseeder for grassland ecological restoration.

[0021] Example: An adjustable seed reseeder for grassland ecological restoration, such as... Figures 1-5 As shown, the device includes a support frame 1, anti-slip wheels 2, a motor 3, a fixing block 4, a fixing column 5, a limiting rod 6, a guide rod 7, a seed box 8, a connecting block 9, a knob 10, a torsion spring 11, a seed metering device 12, and a soil covering wheel 13. Four anti-slip wheels 2 are rotatably connected in a rectangular array at the bottom of the support frame 1. The motor 3 is mounted on the top right side of the support frame 1 via screws. A fixing block 4 is welded to the top left side of the support frame 1, and the fixing block 4 is rotatably connected to the end of the output shaft of the motor 3. A fixing column 5 is welded to the top left side of the support frame 1, and a limiting rod 6 is rotatably connected to the top of the fixing column 5. The limiting rod 6 engages with the fixing block 4. Guide rods 7 are symmetrically welded to the front and back of the middle of the support frame 1. Two guide rods 7 are located on the left and right sides of the output shaft of the motor 3. Five seed boxes 8 are rotatably connected in a linear array from left to right on the output shaft of the motor 3, and each seed box 8 is fitted onto two guide rods 7. Each seed box 8 has a connecting block 9 symmetrically rotated in the middle. Each seed box 8 has an opening at the top for seeds to be placed in, and each seed box 8 is covered with a protective cover 801. The seed box 8 is made of transparent plastic, which has good corrosion resistance and allows operators to observe the seed level and seeding status in real time. Each connecting block 9 is slidably engaged with the output shaft of the motor 3. Each seed box 8 has a knob 10 threadedly connected to the front, and each knob 10 abuts against the front guide rod 7. Each seed box 8 has a seed metering device 12 rotatably connected inside, and each seed metering device 12 is slidably engaged with the output shaft of the motor 3. The left and right sides of the limiting rod 6 are connected to the fixed column 5 with torsion springs 11, and the two torsion springs 11 are wound around the fixed column 5. Five soil covering wheels 13 are welded in a straight line array from left to right on the rear bottom of the support frame 1.

[0022] like Figure 1 and Figure 5As shown, it also includes a water storage tank 14, a water pump 15, a water delivery pipe 16, and nozzles 17. The water storage tank 14 is welded to the rear side of the support frame 1. The water pump 15 is installed at the bottom of the water storage tank 14 by screws. The water delivery pipe 16 is installed at the bottom right side of the support frame 1 by screws. The right side of the water pump 15 is connected to and communicates with the water delivery pipe 16. Five nozzles 17 are connected in a straight array from left to right in the middle of the water delivery pipe 16.

[0023] When using this device for sowing, the operator first places the device on a level surface to ensure its stability. Then, lift the limiting rod 6 upwards to release it from the fixing block 4. At this time, the torsion spring 11 is compressed. Next, pull the fixing block 4 to the left to remove it. Then, place the seed boxes 8 sequentially onto the output shaft of the motor 3 and the guide rod 7 to the right, and adjust the spacing between the various seed boxes 8 to ensure even distribution. After releasing the limiting rod 6, the limiting rod 6 will re-engage with the fixing block 4 under the reset action of the torsion spring 11. Then, rotate the knob 10 clockwise so that the end of the knob 10 is aligned with the fixed block 4. The guide rod 7 is tightly abutted against, thus firmly locking the seed box 8 onto the guide rod 7, providing stable support and guidance, ensuring the smooth and reliable operation of the entire sowing structure. Seeds are then placed into each seed box 8, and the top protective cover 801 is placed on top to prevent external impurities from entering or seeds from accidentally spilling. Then, the motor 3 is started, driving its output shaft to rotate, which in turn drives the seed metering device 12, which is fixedly connected to it, to rotate synchronously. During the rotation of the seed metering device 12, the seeds are carried by its internal structure and fall to the ground under gravity, achieving quantitative and uniform distribution. During the sowing operation, the operator pushes the entire device forward. Four anti-slip wheels 2 at the bottom of the support frame 1 ensure stable operation on the grassland. The soil-covering wheel 13 at the rear of the device covers the sown area with soil as it moves forward, ensuring full contact between the seeds and soil, which is beneficial for subsequent germination and growth. Simultaneously, the water pump 15 is activated, pumping water from the storage tank 14 through the water pipe 16 to five nozzles 17. The nozzles 17 evenly spray water along the sowing area, providing the necessary humidity for seed germination and enhancing the ecological restoration effect. When necessary, additional water can be added... When adding seeds and water, the operator should first turn off the motor 3 and water pump 15 to stop the sowing and watering operations of the device. Then, open the protective cover 801 on the top of the seed box 8, add an appropriate amount of seeds to each seed box 8 in sequence, and then close the protective cover 801 again to prevent external impurities from entering or seeds from accidentally spilling before operation. At the same time, inject enough water into the water storage tank 14 to ensure the needs of subsequent watering operations. After the watering is completed, restart the motor 3 and water pump 15, and the device can resume normal sowing and watering functions to continue grassland ecological restoration operations.
