Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and in particular relates to a no-tillage reseeding machine for grassland ecological restoration. Background Art

[0002] The no-till reseeding machine for grassland ecological restoration is a mechanical equipment specially used for natural grassland ecological restoration. This machine is used to reseed high-quality forage seeds to restore the production capacity of natural grasslands and improve the quality of forage. Specifically, the no-till reseeding machine for grassland ecological restoration usually integrates the functions of loosening soil, ditching, fertilizing (some models), sowing, covering soil and pressing in one, and can complete multiple operations at one time, thereby minimizing the damage to the native vegetation of the grassland and improving the productivity of the grassland. This machine has broad application prospects in the fields of grassland ecological restoration, grassland improvement, and degraded grassland management. In summary, the no-till reseeding machine for grassland ecological restoration is an efficient, environmentally friendly and multifunctional grassland ecological restoration equipment, which is of great significance for protecting and improving the grassland ecological environment.

[0003] At present, the no-till reseeding machines used for grassland ecological restoration are prone to uneven seeding during sowing, dropping multiple seeds at one time. This not only causes seed waste, but also causes competition for living space and nutrients after multiple seeds fall, resulting in low seed survival rate. In addition, the surviving seeds will also lead to reduced forage seed yield due to insufficient nutrients. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes a no-tillage reseeding machine for grassland ecological restoration to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention relates to a no-tillage sowing machine for grassland ecological restoration, comprising a sowing machine, a sowing mechanism being arranged above the sowing machine, the sowing mechanism comprising a driving motor being arranged above the sowing machine, the output shaft of the driving motor being fixedly mounted with a first bevel gear, the first bevel gear being engaged with a second bevel gear, the second bevel gear and the first bevel gear being fixedly mounted on a feed shaft and a stirring shaft respectively, the feed shaft and the stirring shaft being connected through a transmission mechanism, the feed shaft and the stirring shaft being rotatably mounted inside a sowing box, the interior of the sowing box being chamfered, a plurality of first feed ports being provided inside the sowing box, a plurality of seed placement slots being provided on the feed shaft, and a plurality of second feed ports being provided at the bottom of the sowing box.

[0007] Furthermore, the transmission mechanism includes a first gear arranged on the discharge shaft, the first gear is connected to the second gear through a gear belt transmission, the first gear and the second gear are both rotatably mounted on the seeding box, and the drive motor is fixedly mounted above the reseeder.

[0008] Furthermore, several of the first feed openings correspond one-to-one to several of the seed placement slots, the diameters of several of the first feed openings are smaller than those of several of the seed placement slots, several of the seed placement slots correspond one-to-one to the second feed openings, and the diameters of several of the seed placement slots are smaller than those of several of the second feed openings.

[0009] Furthermore, a feed port is fixedly installed above the seeding box, the seeding box is fixedly installed on a fixed plate on which one end of a connecting shaft is fixedly installed, the other end of the connecting shaft is fixed on a connecting piece, and the connecting piece is fixedly installed above the reseeding machine.

[0010] Furthermore, a first motor is fixedly installed above the fixed plate, a threaded rod is fixedly installed on the output shaft of the first motor, the threaded rod is rotatably installed inside the fixed plate, the threaded rod is threadedly connected to a sliding plate, and the sliding plate is slidably connected to the fixed plate.

[0011] Furthermore, a second motor is fixedly mounted above the sliding plate, and a drill rod is fixedly mounted on the second motor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention realizes efficient and uniform stirring and sowing of seeds by designing a sowing mechanism including a drive motor, a bevel gear transmission system, a feed shaft and a stirring shaft. The precisely designed size relationship between the feed port and the seed placement groove effectively prevents seed blockage and ensures that the seeds can be discharged evenly from the second feed port, thereby realizing accurate and uniform sowing in grassland ecological restoration, greatly improving sowing efficiency and seed utilization rate, and reducing waste.

[0017] 2. The present invention integrates the functions of soil opening and covering. Through the combination of a threaded rod and a sliding plate driven by a first motor, and a drill rod driven by a second motor, the drill rod can flexibly open holes in the grassland soil. At the same time, the design of an electric telescopic rod and a covering plate driven by a cylinder enables the soil to be quickly covered after sowing is completed, ensuring that the seeds are properly protected by the soil. This design not only improves the flexibility of sowing operations, but also simplifies the soil treatment process and improves overall work efficiency.

[0018] 3. This invention is equipped with a camera and infrared probe, enabling real-time monitoring and obstacle avoidance during the sowing process. The camera captures and records potential problems encountered during sowing, providing intuitive feedback to the operator; while the infrared probe senses obstacles in the surrounding environment in real time, ensuring safe and stable operation of the machine even in complex terrain. This intelligent design not only improves operational safety but also enhances the machine's adaptability and reliability, providing strong technical support for grassland ecological restoration efforts.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
