Description

TECHNICAL FIELD

[0001] The application relates to the technical field of agricultural machinery, in particular to a synchronous fertilizing type grass seed reseeding device based on high-cold grassland ecological restoration. BACKGROUND

[0002] High-cold grassland is the core ecological barrier of the Qinghai-Tibet Plateau and high-altitude areas, and has multiple functions such as water and soil conservation, biodiversity maintenance and livestock production. Its ecological health directly affects regional ecological safety and economic sustainable development. In recent years, affected by factors such as overgrazing, climate change (such as uneven precipitation, low temperature stress) and human disturbance (such as engineering construction), global high-cold grasslands are generally facing degradation problems, which are manifested as a decrease in vegetation coverage, a decrease in the proportion of high-quality forage grass, a decrease in soil organic matter content and an increase in soil compaction. This not only leads to the decline of grassland productivity, but also causes secondary ecological problems such as water and soil loss and desertification. Therefore, artificial intervention is needed to achieve ecological restoration. At present, grass seed reseeding and soil fertilization are the core technical means for high-cold grassland ecological restoration. However, during the process of grass seed reseeding and soil fertilization, a fertilizing type grass seed reseeding device is needed.

[0003] However, the existing fertilizing type grass seed reseeding device still has some defects when in use. For example, the application number CN202010576548.6 proposes a working machine for grassland no-tillage pipe burying reseeding, which includes a frame body, a first roller, a second roller, a seeding mechanism, a fertilizing mechanism, a seed discharge pipe, a fertilizer discharge pipe, a drip irrigation pipe installation mechanism, a drip irrigation pipe burying mechanism and a furrow opener. The furrow opener includes a fertilizer conveying pipe, a seed conveying pipe, a first shovel wing, a seed distribution box, a second shovel wing and a sword type front blade. The fertilizing mechanism is connected to the fertilizer conveying pipe through the fertilizer discharge pipe, and the seeding mechanism is connected to the seed conveying pipe through the seed discharge pipe. The fertilizer conveying pipe and the seed conveying pipe are welded together, the seed conveying pipe and the seed distribution box are welded together, the front lower end of the fertilizer conveying pipe is embedded with a sword type front blade, the upper segments of the two sides of the fertilizer conveying pipe, the sword type front blade and the seed distribution box are welded with the first shovel wing, and the lower segments of the two sides of the fertilizer conveying pipe, the sword type front blade and the seed distribution box are welded with the second shovel wing. The first shovel wing is arranged on the two sides of the seed distribution box. The purpose of this working machine for grassland no-tillage pipe burying reseeding is to solve the problem of complex structure and poor operability of the seeding machine. However, during the actual use process, the following problems still exist. During the process of grass seed reseeding by the working machine for grassland no-tillage pipe burying reseeding, the working machine is only connected to the single seed discharge pipe and the seed conveying pipe, and all the grass seeds need to be mixed and then seeded through the same channel. There is a lack of independent layered conveying and quantitative control mechanism. Due to the significant difference in flowability between large and small particles (small particles are easy to be blocked by arching, and large particles are easy to be packed by sinking), uneven phenomena such as "local enrichment of small particles and sparse distribution of large particles" may occur during mixed seeding, which may further lead to uneven growth of grass seeds in the later stage, reducing the reseeding effect. At the same time, when the large and small grass seeds are mixedly sown, the two kinds of seeds will compete for nutrients due to the different nutrient absorption capacities, and further, the phenomenon that the large grass seeds have strong fertilizer absorption capacity and the small grass seeds have weak fertilizer absorption capacity will occur, so that the stable three-dimensional structure of "small particles in shallow layer for rapid coverage and large particles in deep layer for long-term stability" cannot be formed.

[0004] In view of this, in view of the above problems, in-depth research is conducted, and the present case is generated.

DETAILED DESCRIPTION

[0025] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0026] Embodiment one: please refer to Figure 1 Figure 9 The present application provides a technical scheme: a synchronous fertilization type grass seed reseeding device based on alpine grassland ecological restoration, comprising a mounting plate 1, support frames 2 are fixedly installed at the bottom of the left and right ends of the mounting plate 1, and rollers 3 are installed at the bottom of the support frames 2, the rollers 3 are provided in three groups, a slotted seeding mechanism is fixedly installed at the front end of the mounting plate 1, a seed storage box one 9 is fixedly connected to the top end of the slotted seeding mechanism, and both ends of the seed storage box one 9 are fixedly connected with the mounting plate 1 through support plates 8, the slotted seeding mechanism comprises a feed pipe 10 which is installed at the bottom of the seed storage box one 9 at equal intervals, an upper positioning plate 11 is fixedly sleeved at the bottom end of the feed pipe 10, a gear ring 12 is rotatably connected to the bottom end of the upper positioning plate 11, a rotating plate 13 is fixedly installed at the inner circle of the gear ring 12, discharge holes 14 are formed in the rotating plate 13 at equal angles, a lower positioning plate 15 is rotatably connected to the bottom surface of the gear ring 12, a discharge pipe 16 is embeddedly installed in the lower positioning plate 15, a protective shell 17 is fixedly connected to the surfaces of the upper positioning plate 11 and the lower positioning plate 15, a cushion block 18 is fixedly installed at the bottom surface of the lower positioning plate 15, the cushion block 18 is fixedly connected with the top surface of the mounting plate 1, a servo motor one 19 is connected to the bottom end of the right end rotating plate 13, the servo motor one 19 is fixedly connected with the right end lower positioning plate 15, the slotted seeding mechanism further comprises a fixed rod 4 which is installed at the bottom surface of the mounting plate 1 at equal intervals, a connecting plate 5 is fixedly connected to the bottom end of the fixed rod 4, a connecting pipe 6 is fixedly installed through the front end of the connecting plate 5, the top end of the connecting pipe 6 is fixedly connected with the bottom end of the discharge pipe 16, and a slotted plate 7 is fixedly sleeved at the bottom end of the connecting pipe 6. The above structure is designed, the seed storage box one 9 is fixed above the mounting plate 1 through the support plates 8, and the inside is pre-filled with large-particle grass seeds to be seeded, the support frames 2 and the rollers 3 at both ends of the mounting plate 1 provide mobile support for the whole device, and before operation, the device is moved to the alpine grassland area to be repaired through the rollers 3, the position of the device is adjusted so that the slotted plate 7 is aligned with the seeding path, and the preparation before seeding is completed. ​When the device is in operation, the right end servo motor 19 is started, and the output shaft of the servo motor 19 directly drives the rotation of the rotating plate 13 connected thereto. Since multiple rotating plates 13 are connected through the gear ring 12, a single servo motor can drive all rotating plates 13 to rotate synchronously. The discharge holes 14 inside the rotating plate 13 rotate with the rotating plate 13. When the discharge hole 14 rotates to align with the outlet of the feeding pipe 10 at the bottom of the upper positioning plate 11, the large-particle grass seeds in the seed storage box 9 fall into the discharge hole 14 through the feeding pipe 10. As the rotating plate 13 continues to rotate, the discharge hole 14 containing the grass seeds rotates to align with the inlet of the discharge pipe 16 embedded in the lower positioning plate 15. The grass seeds naturally fall into the discharge pipe 16 along the discharge hole 14, realizing the core function of "demand-based quantitative seed taking and accurate seed dropping". By adjusting the speed of the servo motor 19, the rotation frequency of the rotating plate 13 can be controlled, and the number of seeds dropped per unit time by the discharge hole 14 can be adjusted, meeting the demand of different alpine grasslands for large-particle grass seed sowing amount, and avoiding "large-particle distribution sparseness". During the quantitative transmission process, the protective shell 17 fixed on the surface of the upper positioning plate 11 and the lower positioning plate 15 forms a closed space, which can block impurities such as gravel, dry grass, and frozen soil in the alpine grassland from entering the gap between the rotating plate 13 and the positioning plate, preventing the impurities from jamming the rotating plate 13 or clogging the discharge hole 14, and ensuring the stable operation of the transmission structure. At the same time, the high-frequency vibration generated by the operation of the servo motor 19 is conducted to the discharge pipe 16 through the lower positioning plate 15, and then conducted to the connecting pipe 6 and the feeding pipe 10 connected thereto through the discharge pipe 16. The vibration can shake off the large-particle grass seeds adhering to the inner wall of the pipeline or the discharge hole 14, avoiding the blockage of the conveying caused by the aggregation of the grass seeds, and ensuring the smoothness of the grass seed conveying channel. The bottom surface of the mounting plate 1 is fixedly connected to the connecting plate 5 through the fixed rod 4. The front end of the connecting plate 5 penetrates the top end of the fixed connecting pipe 6 and is sealingly connected to the bottom end of the discharge pipe 16, forming a complete grass seed conveying path. The slotted plate 7 fixedly sleeved at the bottom end of the connecting pipe 6 has a wedge-shaped structure. During operation, the device is moved along the sowing path by external force, such as a traction device. The slotted plate 7 moves synchronously with the device and cuts into the soil of the alpine grassland, forming a sowing groove with a depth suitable for the planting of large-particle grass seeds on the ground surface. At this time, the large-particle grass seeds conveyed by the quantitative conveying device fall directly into the sowing groove formed by the slotted plate 7, completing the synchronous operation of "grooving and seed dropping", and ensuring the accurate sowing of large-particle grass seeds into deep soil, laying a foundation for the subsequent "long-term stability of deep large-particle growth".
