[0002] Ecological lawns are lawn types that focus on ecological environmental protection. They are composed of grass seeds with strong adaptability, drought tolerance, and stress resistance, and have low maintenance costs. Their characteristics include rich biodiversity, a reasonable hierarchical structure, and strong stability; prominent multifunctionality, which can not only beautify the environment, provide places for viewing, recreation, and sports, but also reinforce the soil and slope protection, purify the air, and maintain ecological balance.

A camera 10 is provided on the upper surface of the first base plate 1.

[0029] Furthermore, a synchronous belt 27 is sleeved between the first rotating rod 14 outside the sowing box 13 to facilitate simultaneous operation. At the same time, a second drive motor is arranged inside the control box 11, and a synchronous belt 27 is also arranged between the output shaft of the second drive motor and the first rotating rod 14, so that the first rotating rod 14 is driven to rotate by the second drive motor.

[0030] A bracket 21 is provided on the second bottom plate 2 , a power supply 20 is provided above the bracket 21 , an armrest 18 is fixedly connected to the bracket 21 , and a control panel 19 is provided on the top of the armrest 18 .

[0031] The triangular support structure of the bracket 21 ensures stable power supply of the power source 20. The internal battery pack adopts a quick-release design and supports hot-swap replacement to achieve continuous operation. The gripping part of the armrest 18 has a built-in pressure sensor.

[0032] The movable rod 6 is bent, and a first driving motor 7 is arranged on the movable rod 6. The output shaft of the first driving motor 7 is connected to the rotating cylinder 22. Two rotating disks 24 are symmetrically arranged between the movable rollers 23 on the rotating cylinder 22. Second movable wheels 25 are sleeved on the surfaces of the rotating disks 24. An air pump 26 and an air chamber 39 are arranged inside the rotating cylinder 22. A plurality of air pipes are arranged between the air chamber 39 and the rotating disks 24, and the air pipes are communicated with the second movable wheels 25. The rotating cylinder 22 is provided with a plurality of air inlet holes corresponding to the air pump 26, and dust covers are arranged on the surfaces of the air inlet holes. The first driving motor 7 adopts frequency conversion control and can automatically adjust the rotation speed of the rotating cylinder 22 according to the forward speed to ensure that the soil covering operation is synchronized with the sowing progress. The bent structure of the movable rod 6 forms a lever amplification effect, enabling the operator to adjust the working angle of the rotating cylinder 22 with less force.

[0033] The dust cover adopts a self-cleaning design, and the surface is coated with a hydrophobic material to prevent mud adhesion when encountering wet soil. The air pump 26 is internally provided with an overload protection device, which automatically reverses and pulses to clean ash when the intake resistance exceeds the threshold value to ensure the continuous and efficient operation of the air path system.

[0034] Furthermore, a self-locking structure is arranged between the first rotating shaft 5 and the first bottom plate 1. By rotating the first rotating shaft 5, the movable rod 6 is driven to adjust the angle, which is convenient for adjusting the height of the rotating cylinder 22, adjusting for uneven roads, and facilitating better soil covering operation for sowing.

[0035] The second movable wheel 25 is set as an airbag. The air pump 26 intakes air through the air inlet, and the gas enters the air chamber 39 and then enters the air pipes inside the rotating disk 24 to achieve the purpose of shrinking or swelling the second movable wheel 25, so that the second movable wheel 25 is set higher than the movable roller 23 for convenient overall movement, or controlling the second movable wheel 25 to shrink so that the movable roller 23 contacts the ground.

[0036] Particularly, the rotating cylinder 22 and the rotating disk 24 are coaxially arranged, and the diameters of the rotating disk 24 and the rotating cylinder 22 are the same, which is convenient for covering the sown lawn with soil by the rotating cylinder 22.

[0037] The length of the movable roller 23 is set greater than the radius of the rotating disk 24. A first baffle 9 is fixedly arranged on the connecting rod 8, and the first baffle 9 extends above the rotating cylinder 22 and is arranged between the two second movable wheels 25.

[0038] A number of mounting frames 30 are provided at the bottom of the first base plate 1. A fixed frame 38 is provided on one side of the mounting frame 30. A movable block 31 is movably arranged in the fixed frame 38. A second baffle 33 is provided at the bottom of the movable block 31. A vertical rod is fixed to the bottom of the second baffle 33. Bearings 37 are movably arranged on both sides of the vertical rod and are connected to a second rotating shaft 36 through the bearings 37. A movable disk 34 is rotatably arranged on the second rotating shaft 36. A spring 32 is sleeved outside the movable block 31. The two ends of the spring 32 are respectively connected to the fixed frame and the second baffle 33.

[0039] A number of electric push rods are also correspondingly provided on the first base plate 1 for the movable block 31, to control whether the movable block 31 and the movable disk 34 are in contact with the sowing area.

[0040] A scraper is provided on one side of the second baffle 33 close to the movable disk 34. A gap is left between the scraper and the movable disk 34 to facilitate scraping the soil on the movable disk 34.

[0041] It should be noted that the first movable wheel 4 provided at the end of the first electric telescopic machine 3 is anti-slip, and the height of the first movable wheel 4 can be adjusted through the first electric telescopic machine 3 to facilitate adjusting the overall height of the device.

[0042] The overall three-dimensional attitude adjustment of the device is achieved through the cooperation of the spring 32 and the movable block 31. When encountering uneven ground, the movable disk 34 can deflect around the second rotating shaft 36, and at the same time, the compression amount of the spring 32 automatically changes to keep the grounding pressure constant. The soil scraping design of the second baffle 33 can remove the soil attached to the surface of the movable disk 34 to prevent slipping. The bearings 37 adopt a sealed grease lubrication structure to adapt to the humid and muddy environment. The quick-disassembly design of the mounting frame 30 allows for replacing the movable disks 34 of different specifications.

[0043] Mounting holes 28 are correspondingly provided at the bottom of the sowing box 13 for the extension cylinders 29. The second rotating rod 16 extends into the interior of the extension cylinders 29, and a guide plate 17 is provided on the surface of the second rotating rod 16. The movable disks 34 are all arranged close to the extension cylinders 29.

[0044] The spiral layout of the guide plate 17 forms a seed acceleration channel, increasing the falling speed to 2 - 3 m / s to ensure accurate soil entry. The inner wall of the extension cylinder 29 is coated with ultra-high molecular weight polyethylene material to reduce the seed friction damage rate. The mounting holes 28 are designed with a tapered flared opening, and a sealing ring is provided at the bottom of the mounting holes 28, which is convenient for the disassembly, installation and maintenance of the second rotating rod 16 and also prevents the leakage of small seeds.

[0045] The inside of the fixed sleeve 15 is hollowly arranged. The first rotating rod 14 penetrates through the fixed sleeve 15. An active gear is sleeved on the first rotating rod 14 inside the fixed sleeve 15. The top of the second rotating rod 16 extends into the fixed sleeve 15 and is sleeved with a driven gear. The active gear and the driven gear are meshed with each other. The bottom of the fixed sleeve 15 is provided with an extension sleeve, and a through hole corresponding to the second rotating rod 16 is opened in the middle of the extension sleeve.

[0046] Both the active gear and the driven gear are straight bevel gears, which are used to realize the right-angle transmission between the first rotating rod 14 and the second rotating rod 16.

[0047] Among them, the camera 10 extends to the bottom of the first bottom plate 1 and is arranged in the direction of the movable wheel 34 and the extension cylinder 29, which is convenient for observing the sowing area. When there is jamming or grass seeds getting stuck, it is easy to quickly discover and make adjustments. Above the power supply 20, a storage box 12 is also installed through a bracket.

[0048] Working principle: When the device is in use, the double-bottom plate design of the first bottom plate 1 and the second bottom plate 2 forms a modular operation platform. The first bottom plate 1 bears the sowing core components, and the second bottom plate 2 integrates the power and control systems. The first electric telescopic machine 3 adjusts the height of the first movable wheel 4, thereby adjusting the overall inclination angle of the device, making the device adapt to terrains with different slopes and facilitating the construction of uneven ecological lawns;

[0049] By filling the sowing box 13 with grass seeds, the sowing box 13 adopts a dual-channel seed supply design. The two first rotating rods 14 achieve synchronous rotation speed through the synchronous belt 27, ensuring that the seeds are evenly distributed to each sowing unit. The bevel gear transmission system in the fixed sleeve 15 converts the horizontal rotation into the vertical movement of the second rotating rod 16. The spiral structure of the guide plate 17 accelerates the falling of the seeds and reduces the aerial drift. The guide plate 17 sends the grass seeds into the extension cylinder 29 for sowing, completing the sowing operation;

[0050] By rotating the first rotating shaft 5 to adjust the position of the movable rod 6, and then adjusting the height of the rotating cylinder 22. When it is necessary to move and no sowing operation is required, the air pump 26 intakes air, and the second movable wheel 25 is lifted through the air cavity 39, so that the second movable wheel 25 contacts the ground, avoiding the contact of the rotating cylinder 22 and the movable roller 23 with the ground, and improving the service life of the rotating cylinder 22. When it is necessary to perform sowing and soil covering operations, the air pump 26 deflates, so that the rotating cylinder 22 contacts the lawn and the movable roller 23 contacts the ground, and the rotating cylinder 22 performs soil covering operations on the just-sown area;

[0051] When the movable disk 34 contacts the land, it moves in an S shape, which is convenient for planning the grass seed planting area and for checking the planting area after sowing. The movable block 31 works in coordination with the spring 32 through the electric push rod to achieve three-dimensional terrain adaptation. When a local depression is detected, the electric push rod retracts the movable block 31, and the spring 32 releases the pressure to make the movable disk 34 sink and fit the ground; the electric push rod lifts the raised area, and the spring 32 is compressed to avoid excessive downward pressure. The gap between the scraper of the second baffle 33 and the movable disk 34 is adjustable, which can scrape off the attached soil and avoid friction loss. The bearing 37 of the movable disk 34 adopts a labyrinth seal design to adapt to the muddy environment during the rainy season or after irrigation. Movable disks of different specifications support quick replacement.
