Description

Technical Field

[0001] The present invention relates to the technical field of degraded grassland ecological restoration, and specifically to a seeding device for degraded grassland ecological restoration Background Art

[0002] Degraded grassland ecological restoration refers to a series of ecological, management, and engineering technical measures taken to address the problems of the degradation of the grassland ecosystem structure and function caused by natural factors (such as climate change, soil erosion, etc.) or human activities (such as overgrazing, unreasonable reclamation, etc.), in order to restore or improve the health status, productivity, and biodiversity of the grassland ecosystem.

[0003] This process aims to reverse the degradation trend of the grassland and restore its original ecological service functions, such as providing forage resources, maintaining biodiversity, regulating the climate, and conserving water and soil. Restoration measures may include restricting grazing, improving the soil, planting suitable grass seeds, implementing soil and water conservation projects, and restoring wetland ecosystems. Through these measures, the grassland coverage can be gradually restored, soil fertility can be improved, and species diversity can be increased, thus constructing a more stable and sustainable grassland ecosystem.

[0004] The current method for degraded grassland ecological restoration is mainly to sow grass seeds on the degraded grassland and sprinkle water to make the grass seeds germinate and grow, ultimately achieving the purpose of restoration.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1-11 , the present invention provides a technical solution:

[0040] A seeding device for ecological restoration of degraded grasslands includes a storage cylinder 4 filled with a mixture of grass seeds and soil, and a mounting frame for mounting the storage cylinder 4 on a tractor. The mixture of grass seeds and soil refers to a mixture formed by stirring and mixing grass seeds, soil, and water in a certain proportion. The advantage of using this method is that the soil contains the nutrients required for the growth and germination of grass seeds. At the same time, mixing the grass seeds and soil together can protect the grass seeds and prevent the grass seeds from being blown away by strong winds, which is conducive to the growth and germination of grass seeds and improves the restoration effect of degraded grasslands. Among them, the mounting frame includes a vertical frame 1 and a bottom bracket 2. The bottom bracket 2 is fixedly installed at the bottom end of the vertical frame 1, and the storage cylinder 4 is arranged on the top of the bottom bracket 2. A vertically telescopic telescopic rod 3 is fixedly installed on the mounting frame. The telescopic rod 3 can be one of an oil cylinder, a cylinder, or an electric cylinder. The telescopic end of the telescopic rod 3 is fixedly connected to a sealing cover 5, and the sealing cover 5 is slidably and sealingly installed inside the storage cylinder 4. Specifically, the telescopic rod 3, the storage cylinder 4, and the sealing cover 5 cooperate to form a device similar to an extruder. A plurality of discharge pipes 6 are arranged at the bottom of the storage cylinder 4. The discharge pipes 6 include an inclined pipe 61 and an upper pipe 62 and a lower pipe 63 respectively fixedly connected and communicated with the upper and lower ends of the inclined pipe 61. The upper pipe 62 is rotationally and sealingly connected to the storage cylinder 4.

[0041] The specific material and shape of the storage cylinder 4 are not specifically limited in this embodiment. For example, the storage cylinder 4 can be made of stainless steel, and its shape can be the cylindrical shape in the figure.

[0042] The working principle of the above solution is as follows: The telescopic rod 3 is directly used to push the sealing cover 5 to move downward inside the storage cylinder 4. The grass seed and soil mixture inside the storage cylinder 4 will be discharged through a plurality of discharge pipes 6 under the extrusion force of the sealing cover 5. Also, during the process of discharging the grass seed and soil mixture, the entire device is towed by a tractor for movement. Moreover, the discharge pipe 6 is rotatable and the lower pipe 63 rotates around the axis of the upper pipe 62. Therefore, the grass seed and soil mixture discharged from the discharge pipe 6 can form a Figure 11 similar line trajectory. Among them, there is partial overlap between adjacent two line trajectories, and a plurality of line trajectories cooperate together to form a net structure for protecting against wind and sand, which can not only protect the grass seeds from being blown away by strong winds, but also provide nutrients for the grass seeds, and at the same time has the effect of fixing sand to prevent the grassland from further degrading.

[0043] A number of discharge pipes 6 are arranged at equal intervals in the first direction F1; the storage cylinder 4 moves along the second direction F2 under the traction of the tractor; wherein, there is an included angle between the first direction and the second direction. The purpose of such a setting is to make the overlapping area of the line trajectories of the grass seed and soil mixture discharged from a number of discharge pipes 6 larger, so as to make the effect of preventing and fixing wind and sand better.

[0044] A support plate 19 is fixed to the top of the bottom bracket 2, and the storage cylinder 4 is arranged on the top of the support plate 19; the upper pipe 62 is rotatably connected to the support plate 19 through a mechanical seal 11. A docking hole 13 is provided in the bottom of the storage cylinder 4 corresponding to the discharge pipe 6. A docking head 64 matching the docking hole 13 is sleeved and fixed at the top end of the upper pipe 62, and the upper surface of the docking head 64 is a conical surface; in the above technical solution, the storage cylinder 4 and the bottom bracket 2 are set to be detachably connected. When the grass seed and soil mixture filled inside the storage cylinder 4 is completely extruded, the emptied storage cylinder 4 can be directly removed and replaced with a storage cylinder 4 filled with grass seed and soil mixture, which is beneficial to improving the actual working efficiency.

[0045] A motor 7 is fixedly installed on the bottom bracket 2. A driving wheel is fixed on the output shaft of the motor 7. A chain wheel 8 is sleeved and installed on the upper pipe 62. The driving wheel and a number of chain wheels 8 are connected by a chain 9 in transmission; the motor 7 can drive a number of discharge pipes 6 to rotate together through the chain and sprocket structure.

[0046] A same protective cover 10 is arranged outside the driving wheel and a number of chain wheels 8. The protective cover 10 is used to protect the chain and sprocket structure, and the upper pipe 62 is rotatably connected to the protective cover 10 through a bearing 12.

[0047] A baffle plate 14 is provided at the bottom of the storage cylinder 4. The baffle plate 14 has a closed position for blocking the docking hole 13 and an open position for opening the docking hole 13. One side of the baffle plate 14 is fixedly connected with a connecting rod 15, and one end of the connecting rod 15 extends through the outside of the storage cylinder 4 in a sliding and sealing manner. By pulling the connecting rod 15, the baffle plate 14 can be adjusted between the closed position and the open position.

[0048] A side enclosure 17 is fixedly connected to the top of the support plate 19. The side enclosure 17 is integrally annular and is used to limit the position of the storage cylinder 4 to prevent the storage cylinder 4 from slipping sideways. An opening 171 is provided on the side enclosure 17, and two oppositely arranged support plates 18 are fixed at the position of the opening 171. A communicating card slot 181 and an inlet / outlet 182 are provided on the support plates 18. The card slot 181 is used to limit the position of the handle rod 16. One end of the connecting rod 15 is fixedly connected with the handle rod 16, and the handle rod 16 can enter the card slot 181 through the inlet / outlet 182.

[0049] A positioning cylinder 20 is fixedly connected to the bottom bracket 2, and a positioning column 21 is fixedly connected to the side of the storage cylinder 4. The positioning column 21 is arranged in a matching manner with the positioning cylinder 20. The cooperation of the positioning cylinder 20 and the positioning column 21 enables the docking hole 13 and the docking head 64 to be quickly docked when the storage cylinder 4 is replaced, improving the replacement efficiency.

[0050] A rotating shaft 23 is fixedly connected to the top of the vertical frame 1. A cross frame 22 is rotatably connected to the rotating shaft 23, and the top end of the telescopic rod 3 is installed on the cross frame 22. In this way, the entire telescopic rod 3 can rotate around the axis of the rotating shaft 23. When replacing the storage cylinder 4, the telescopic rod 3 and the sealing cover 5 can be moved away from directly above the storage cylinder 4 by rotation.

[0051] Two side ears 24 are fixedly provided on the side of the storage cylinder 4. The two side ears 24 are oppositely arranged. The arrangement of the side ears 24 facilitates lifting and removing the storage cylinder 4 by using a forklift or the like when replacing the storage cylinder 4.

[0052] The replacement method of the storage cylinder 4 is as follows: directly use the telescopic rod 3 to directly extract the sealing cover 5 from the inside of the storage cylinder 4 and lift it to a suitable position. Then push the baffle plate 14 to convert it from the open position to the closed position to ensure that the handle rod 16 can smoothly exit from the inside of the card slot 181 through the inlet / outlet 182. Then use equipment such as a forklift to lift the side ear 24 to lift and remove the storage cylinder 4, and then place the storage cylinder 4 filled with the grass seed and soil mixture at the designated position.
