[0002] Existing grass seed spreading systems for desertified grasslands primarily address grassland degradation and desertification, aiming to restore vegetation and improve the ecological environment through mechanical seed dissemination. These systems typically consist of a spreading mechanism, a seed storage system, and a seed control system. The seeding mechanism is typically a tractor or specialized spreading vehicle, adaptable to varying terrain and climatic conditions. The seed storage system is designed to ensure uniform and active seed distribution during the seeding process, while the seed control system ensures uniform coverage of the target area by precisely controlling the seeding rate and speed.

[0003] However, existing technologies have limitations, such as insufficient seeding uniformity, poor adaptability to complex terrain, and low seeding efficiency. Furthermore, some devices fail to adequately protect grass seeds during seeding, resulting in low seed survival rates in harsh environments. Therefore, developing more efficient, adaptable, and uniform seeding devices is crucial for improving desertified grasslands and promoting ecological restoration.

[0034] The following describes three implementation methods of the present application in detail with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figures 1-6 Shown is a solar-powered grass seed spreading device for desertified grasslands, comprising a main support 1 with a pair of wheels, on which a plurality of evenly distributed spreading structures are mounted;

[0037] The sowing structure includes a grass seed box 2, which includes a conical shell 21 hinged to the main bracket 1. The top of the conical shell 21 is fixedly connected to the main seed box 22, and the lower end of the main seed box 22 is provided with a secondary seed box 23.

[0038] A spreading pipe 3 is provided on the lower side of the grass seed box 2. The spreading pipe 3 includes a wide-mouth cone 31 mounted on a guide wheel bracket. A connecting cover 32 and a long straight pipe 33 are respectively installed at the upper and lower ends of the wide-mouth cone 31. A mixing structure 4 is connected between the connecting cover 32 and the output end of the conical shell 21.

[0039] The mixing structure 4 includes a rectangular shell 41 communicating with the conical shell 21 , a guide wheel 42 is rotatably connected in the rectangular shell 41 , and a material delivery hose 43 is connected between the rectangular shell 41 and the connecting cover 32 ;

[0040] The main bracket 1 is connected to a plurality of auxiliary material tanks 5 that match the positions of the grass seed boxes 2. The auxiliary material tanks 5 are used to store and transport auxiliary materials, which include liquid fertilizers or water-retaining agents. The auxiliary material tanks 5 are equipped with a delivery pump. A guide pipe 51 is connected between the output end of the auxiliary material tank 5 and the connecting cover 32. An atomizing nozzle 52 that is in communication with the guide pipe 51 is installed at the bottom end of the long straight pipe 33. The auxiliary material is transported to the atomizing nozzle 52 and sprayed out in atomized form through the action of the delivery pump and the guide pipe 51.

[0041] The guide wheel support comprises a mobile chassis, with a connecting arm hinged between the mobile chassis and the main support 1 for securing the spreader tube 3. Mounted on the main support 1 is an extension arm for connecting to the conical shell 21, with a buffer connected between the extension arm and the connecting arm. The feed hose 43 comprises a corrugated conduit, sealed at its junction with the rectangular shell 41 and the connecting cover 32. When one wheel sinks, the buffer releases its elastic potential energy, pushing the connecting arm to lift the spreader tube, preventing damage from contact with the ground. The guide wheel support system, formed by the connecting arm and the buffer, dynamically adjusts the spreader tube's angle and height to adapt to the undulating conditions of the desertified surface.

[0042] The output ends of the auxiliary seed box 23 and the main seed box 22 are both equipped with spiral feeders. The material output end of the main seed box 22 is located directly above the magnetic diversion block 25, and the output end of the auxiliary seed box 23 is close to the inner wall of the conical shell 21. After the material in the auxiliary seed box 23 is output, it falls along the inner wall of the conical shell 21. The materials output by the auxiliary seed box 23 and the main seed box 22 are mixed at the mixing structure 4.

[0043] This device is powered by solar energy and combines multi-level grass seed storage, dynamic mixing and synchronous spraying of auxiliary materials to achieve efficient grass seed spreading in desertified grasslands.

[0044] The main seed tank 22 and auxiliary seed tank 23 contain different grass seeds or seeds at different stages of processing, with a controllable feed rate. Grass seeds from the seed tank 2 collide and mix in the mixing mechanism 4. Then, at the wide-mouthed cone 31 of the spreading tube 3, they combine with liquid auxiliary materials, such as water-retaining agents or fertilizers, provided by the auxiliary material tank 5 to form a "grass seed-auxiliary material" mixture for spreading.

[0045] The mixed material is guided to the ground surface through the long straight pipe 33 via the spreading pipe 3, and the atomized auxiliary material covers the surface of the grass seed; the device integrates the sowing, mixing, auxiliary material application and terrain adaptation functions through modular design, which can easily improve the operational efficiency of desertified grassland management and the survival rate of grass seeds.

[0046] Second implementation method:

[0047] Figure 5-Figure 6As shown, an elastic guide piece 24 is installed at the output end of the conical shell 21, and the bottom end of the elastic guide piece 24 is in contact with the surface of the guide wheel 42. A magnetic shunt block 25 matching the elastic guide piece 24 is provided in the conical shell 21, and the magnetic shunt block 25 is fixedly connected to the connecting shaft 63. The magnetic shunt block 25 includes a shunt cone body, and an electromagnet is installed at the lower end of the shunt cone body; the elastic guide piece 24 includes a fixed end fixedly connected to the conical shell 21, and an elastic part is connected to the bottom of the fixed end. The elastic part includes an elastic spring. A brake pad is laid on one end of the elastic spring close to the guide wheel 42, and a magnetic layer is laid on the other end. When the electromagnet is working, it attracts or repels the elastic part.

[0048] However, when the electromagnet repels the elastic part, the elastic guide piece 24 pressurizes the guide wheel 42, thereby preventing the guide wheel 42 from rotating accidentally, avoiding vibration and other unexpected situations that cause the guide wheel 42 to rotate inactively, and avoiding the accidental discharge of grass seeds due to the accidental rotation of the guide wheel 42.

[0049] However, when the electromagnet and the elastic part are attracted, the elastic part quickly tilts up, causing some of the grass seeds on the elastic part to be thrown to one side of the guide wheel 42. At the same time, some of the mixed grass seeds can be discharged through the gap between the elastic part and the guide wheel 42, which on the one hand helps to mix the grass seeds and on the other hand helps to clear the blockage on the upper side of the guide wheel 42.

[0050] An auxiliary adjustment structure 6 is installed on the main bracket 1, and the auxiliary adjustment structure 6 includes an auxiliary frame 61 with an auxiliary motor. A rotating shaft 62 and a connecting shaft 63 are respectively installed at the upper and lower ends of the auxiliary frame 61. The rotating shaft 62 passes through multiple rectangular shells 41 and is fixedly connected to multiple guide wheels 42. The rotating shaft 62 is connected to the power output end of the motor, and the connecting shaft 63 is fixedly connected to multiple magnetic shunt blocks 25.

[0051] When the auxiliary motor is working, the rotating shaft 62 drives the plurality of guide wheels 42 to rotate, thereby causing the guide wheels 42 to guide the grass seeds in the rectangular shell 41 to be discharged;

[0052] This embodiment effectively prevents the involuntary rotation of the guide wheel 42 by adding an elastic guide piece 24 and a magnetic diverter block 25, thus avoiding accidental discharge of grass seeds and assisting in mixing and clearing blockages. The auxiliary adjustment structure ensures stable driving of the guide wheel 42, ensuring orderly discharge of grass seeds.

[0053] This embodiment makes it easy to quickly stop and continue the grass seed sowing, avoiding the accidental discharge of a large amount of grass seeds retained in the sowing structure after the sowing work is temporarily stopped during the grass seed sowing process; in particular, this solution does not use a valve for shut-off, which is more prone to seed jamming than conventional valve control: this embodiment uses an elastic guide plate 24 + electromagnet linkage design to replace the mechanical valve, and uses magnetic repulsion to pressurize the brake plate to lock the guide wheel 42, and the magnetic attraction force quickly clears the blockage, which is easier to reduce the mechanical failure rate than the traditional shut-off valve.

[0054] The third implementation method:

[0055] Figure 7 As shown, a solar panel is mounted on top of the seed box 2, powering the spreading mechanism and delivery pump. Multiple evenly distributed power connection units are mounted on the connecting shaft 63, with cables running through the connecting shaft 63 to match these connection units. The solar panel generates electricity, and the energy storage battery, integrated into the main bracket or deployed independently, converts solar energy into electrical energy, which is then stored in an onboard battery to power the drive motor, vibrating discharger, screw conveyor, and delivery pump. The introduction of the solar panel not only enables green energy drive for the device but also ensures a stable power supply for the spreading mechanism and delivery pump.

[0056] It also includes an auxiliary spreading system, which includes a single-chip microcomputer installed on the main bracket 1, and the single-chip microcomputer is connected to a control module, a power supply management module, a monitoring module and a data processing module;

[0057] The control module is used to control the spreading structure and the auxiliary motor to work according to the instructions of the data processing module;

[0058] The power supply management module is used to manage the power supply distribution of the solar panels;

[0059] The monitoring module is used to collect data on the working status of the sowing mechanism; weight sensors are installed in the main seed box 22, the auxiliary seed box 23, and the auxiliary material tank 5; when the weight sensor detects that the grass seeds or auxiliary materials in the main seed box 22, the auxiliary seed box 23, or the auxiliary material tank 5 are insufficient, the data processing module will send a command to the control module, which will instruct the sowing mechanism to suspend operation and issue an alarm to prompt the operator to replenish the grass seeds or auxiliary materials;

[0060] The data processing module is used to process and analyze the monitoring data and adjust the operation of the designated equipment according to the analysis results, for example, adjusting the feeding of the grass seed box 2 in the sowing structure and the operation of the auxiliary motor in the auxiliary adjustment structure 6;

[0061] This embodiment utilizes solar panels for power supply, combined with an intelligent auxiliary spreading system, to achieve efficient energy utilization and intelligent control of the spreading device. The device monitors material weight in real time, providing timely warnings and adjustments to operating conditions, ensuring continuity and accuracy in spreading operations.

[0062] In summary, this solution achieves efficient and precise grass seed dissemination in desertified grasslands through functional modules such as multi-level grass seed storage, dynamic mixing, synchronized spraying of auxiliary materials, and intelligent control. Powered by renewable energy, the device boasts a compact structure and strong adaptability, significantly improving operational efficiency and grass seed survival rates in desertified grassland management.

[0063] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
