Technical Field

[0001] The invention relates to the technical field of ecological restoration of degraded grasslands, and in particular to a grass seed sowing device for ecological restoration of degraded grasslands. Background Art

[0002] Ecological restoration of degraded grassland refers to the adoption of a series of ecological, management and engineering technical measures to restore or improve the health, productivity and biodiversity of grassland ecosystems in response to the degradation of 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.).

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

[0020] See also Figure 1-Figure 11 , the present invention provides a technical solution: A grass seed sowing device for ecological restoration of degraded grasslands comprises a storage cylinder 4 with a mixture of grass seeds and soil inside and a mounting frame for mounting the storage cylinder 4 on a tractor. The grass seed and soil mixture 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 nutrients required for the growth and germination of grass seeds. At the same time, mixing grass seeds and soil together can protect the grass seeds and prevent the problem of strong winds blowing the grass seeds away, which is conducive to the growth and germination of grass seeds and improves the restoration effect of degraded grasslands. The mounting frame comprises a vertical frame 1 and a bottom bracket 2, and the bottom bracket 2 is fixed to the bottom bracket 2. It 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, and the telescopic rod 3 can be one of an oil cylinder, an air cylinder or an electric cylinder, and the telescopic end of the telescopic rod 3 is fixedly connected with a sealing cover 5, and the sealing cover 5 is slidably and sealedly 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, and a plurality of discharge pipes 6 are arranged at the bottom of the storage cylinder 4, and the discharge pipe 6 includes an inclined tube 61 and an upper tube 62 and a lower tube 63 respectively fixedly connected to the upper and lower ends of the inclined tube 61, and the upper tube 62 and the storage cylinder 4 are connected by a rotating seal.

[0021] The specific material and shape of the storage tube 4 are not specifically limited in this embodiment. For example, the storage tube 4 can be made of stainless steel and its shape can be cylindrical as shown in the figure.

[0022] The working principle of the above scheme is: directly use the telescopic rod 3 to push the sealing cover 5 to move downward inside the storage tube 4, and the grass seed and soil mixture inside the storage tube 4 will be discharged through multiple discharge pipes 6 under the extrusion force of the sealing cover 5. In addition, since the entire device is towed and moved by a tractor during the process of discharging the grass seed and soil mixture, and the discharge pipe 6 is rotatable and the lower pipe 63 rotates around the axis of the upper pipe 62, the grass seed and soil mixture discharged from the discharge pipe 6 can be formed into a Fig.11 Similar line tracks, in which two adjacent line tracks are partially overlapped, can form a network structure to protect against wind and sand. It 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 and preventing the grassland from further degradation.

[0023] A plurality of discharge pipes 6 are arranged equidistantly in a first direction F1; the storage cylinder 4 moves along a second direction F2 under the traction of a tractor; wherein, there is an angle between the first direction and the second direction. The purpose of such an arrangement is to make the line trajectories of the grass seed-soil mixture discharged from the plurality of discharge pipes 6 have a larger overlapping area, so as to achieve a better effect in preventing wind and sand.

[0024] 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 tube 62 is rotatably connected to the support plate 19 through a mechanical seal 11, and a docking hole 13 is opened at the bottom of the storage cylinder 4 corresponding to the discharge pipe 6, and a docking joint 64 matching the docking hole 13 is sleeved and fixed to the top of the upper tube 62, and the upper surface of the docking joint 64 is a conical surface; in the above technical scheme, a detachable connection is set between the storage cylinder 4 and the bottom bracket 2. When the grass seed and soil mixture filled in the storage cylinder 4 is completely squeezed out, the emptied storage cylinder 4 can be directly removed and replaced with a storage cylinder 4 filled with the grass seed and soil mixture, which is beneficial to improve the actual work efficiency.

[0025] A motor 7 is fixedly mounted on the bottom bracket 2, a driving wheel is fixed on the output shaft of the motor 7, a sprocket 8 is sleeved on the upper tube 62, and the driving wheel and the plurality of sprockets 8 are connected by a chain 9; the motor 7 can achieve the purpose of driving the plurality of discharge pipes 6 to rotate together through the chain and sprocket structure.

[0026] The outer sides of the driving wheel and the plurality of sprockets 8 are provided with a same protective shell 10 , which is used to protect the chain and sprocket structure. The upper tube 62 is rotatably connected to the protective shell 10 via a bearing 12 .

[0028] The top of the support plate 19 is fixedly connected to a side enclosure 17, which is annular as a whole and is used to limit the position of the storage tube 4 to prevent the storage tube 4 from sliding sideways. An opening 171 is provided on the side enclosure 17, and two relatively arranged support plates 18 are fixed at the position of the opening 171. The support plates 18 are provided with a connected card slot 181 and an inlet and outlet 182; 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 to the handle rod 16, and the handle rod 16 can enter the card slot 181 through the inlet and outlet 182.

[0029] 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 matched with the positioning cylinder 20.
