Description

Technical Field

[0001] This invention relates to the field of ecological planting technology, specifically to a grass seed sowing device for green space ecological restoration. Background Technology

[0002] Grass seed spreading devices are needed for planting in green spaces. Grass seed spreading devices (commonly known as seeders) are equipment that uses gravity, centrifugal force or wind to spread grass seeds evenly on the ground surface. They are mainly used in lawn establishment, slope greening, mine revegetation and other scenarios.

[0003] Currently, most existing technologies employ ground sowing. In contrast, Chinese invention publication CN 119156907B discloses a grass seed sowing device for ecological restoration. This device uses a soil-turning mechanism to further crush the compacted soil after turning, increasing soil looseness and facilitating effective grass seed sowing. Furthermore, during the crushing process, the crushing state of the turning mechanism can be adjusted in real-time according to the size of the compacted soil clods, effectively treating the clods and ensuring the uniformity of grass seed distribution during sowing and the effectiveness of water penetration during subsequent irrigation, thus guaranteeing the efficiency of soil ecological restoration. However, when facing sloping ground, the feed hopper tilts. A slightly steep slope leads to uneven loading and uneven distribution, with faster distribution uphill and slower distribution downhill, or even breakage on one side. Moreover, it cannot guarantee uniform distribution, resulting in uneven turf density later, requiring manual reseeding, increasing the workload of workers, and reducing the efficiency of ecological restoration. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a grass seed sowing device for green space ecological restoration, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a grass seed sowing device for green space ecological restoration, comprising a drone body, a storage tank disposed within the drone body, and the drone body and the storage tank connected by an orientation adjustment mechanism, the orientation adjustment mechanism comprising a first rotating seat and a second rotating seat; the first rotating seat is rotatably connected to the top of the storage tank, the second rotating seat is rotatably connected to the drone body, a first arc-shaped seat is fixedly connected to the first rotating seat, and a second arc-shaped seat is fixedly connected to the second rotating seat, the first arc-shaped seat and the second arc-shaped seat are connected by a cross rod; a feeding hopper, a sealing cover and a distributing plate are sequentially disposed below the storage tank, the distributing plate is fixedly connected to multiple partitions, a material fixing component is disposed at the bottom of the storage tank, and a second motor is disposed between the storage tank, the distributing plate and the feeding hopper to jointly drive the material fixing component and the distributing plate.

[0006] It also includes that the ends of the cross rod are rotatably connected to the first arc-shaped seat and the second arc-shaped seat respectively, and that the top of the storage box is provided with a feed inlet.

[0007] It also includes a cylindrical cavity at the bottom of the storage box, a discharge port on the cylindrical cavity, and a rotating shaft rotatably connected inside the cylindrical cavity, with multiple dials fixedly connected to the rotating shaft.

[0008] It also includes that the feed hopper is located below the dial wheel, the feed hopper and the sealing cover are fixedly connected, and the sealing cover and the distributing disc are rotatably connected.

[0009] It also includes a circular hole on the sealing cover, which is connected to the feed hopper, and an arc-shaped opening on the side wall of the sealing cover.

[0010] It also includes a second motor located below the material distribution plate and its output end fixedly connected to the material distribution plate. The output end of the second motor is equipped with a gearbox, and the second motor drives the rotating shaft to rotate through the gearbox.

[0011] It also includes a discharge port on the outer wall of the storage box, the arc-shaped opening and the discharge port cooperating, a windproof mechanism installed on the discharge port, the windproof mechanism including a mounting base, two mounting bases fixedly connected to the storage box and located above the discharge port, a roller rotatably connected to the two mounting bases, an upper baffle cloth wound on the roller, side baffle cloths connected to both sides of the upper baffle cloth, a connecting base fixedly connected to the mounting base, a rotating rod rotatably connected to the connecting base, a mounting plate rotatably connected to the end of the rotating rod away from the connecting base, and the upper baffle cloth and the mounting plate connected.

[0012] It also includes a worm gear fixedly connected to the end of the reel, the worm gear being rotatably connected to the mounting base, a first motor installed inside the storage box, and a worm fixedly connected to the output end of the first motor, the worm meshing with the worm gear.

[0013] It also includes a mounting frame fixedly connected to the storage box, the second motor fixedly connected to the mounting frame, and a support frame fixedly connected to the storage box, the support frame being used to fix the sealing cover and the motor.

[0014] It also includes landing gear installed on the front and rear sides of the drone body, a set of connecting rods on the left and right sides of the drone body, with two connecting rods in each set, and wings installed at the ends of the connecting rods. The outer wall of the storage box has a discharge port, and the arc-shaped opening cooperates with the discharge port.

[0015] The technical solution provided by this invention has the following advantages compared with the prior art: This invention, by incorporating an orientation adjustment mechanism, can adjust the tilt angle of the storage bin, ensuring it remains perpendicular to the ground. This prevents uneven loading or even breakage of the distribution disc during sowing due to the drone's flight attitude causing the storage bin to become unbalanced. Furthermore, a single motor can simultaneously drive both the positioning component and the distribution disc, reducing the number of power components required and lowering the overall weight of the device. This makes it more suitable for drone-borne sowing operations. The positioning component controls the speed of seed discharge, thereby controlling the seeding density. The distribution disc, in conjunction with spacers, evenly distributes the seeds, resulting in better uniformity compared to traditional spot-drop sowing methods, effectively improving the seeding effect during green space ecological restoration.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Example 1: Please see Figures 1-9 This invention provides a technical solution: a grass seed sowing device for green space ecological restoration, comprising a drone body 1, a storage tank 2 inside the drone body 1, the drone body 1 and the storage tank 2 being connected by an orientation adjustment mechanism 6, the orientation adjustment mechanism 6 including a first rotating seat 61 and a second rotating seat 62; the first rotating seat 61 is rotatably connected to the top of the storage tank 2, the second rotating seat 62 is rotatably connected to the drone body 1, a first arc-shaped seat 63 is fixedly connected to the first rotating seat 61, and a second arc-shaped seat 64 is fixedly connected to the second rotating seat 62, the first arc-shaped seat 63 and the second arc-shaped seat 64 being connected by a cross rod 65; a feeding hopper 5, a sealing cover 3 and a distributing plate 4 are sequentially arranged below the storage tank 2, the distributing plate 4 is fixedly connected to a plurality of partitions 401, a fixing component is arranged at the bottom of the storage tank 2, and a second motor 11 is arranged between the storage tank 2, the distributing plate 4 and the feeding hopper 5 to jointly drive the fixing component and the distributing plate 4.

[0022] In practice: The orientation adjustment mechanism 6 not only connects the storage box 2 and the drone body, but also keeps the storage box 2 perpendicular to the ground. This prevents the storage box 2 from being unbalanced due to the drone's flight attitude during the sowing process, causing the tilt angle of the distribution plate 4 to change, resulting in uneven material feeding or even material breakage on one side.

[0023] Please see Figure 5 The present invention provides a technical solution: the bottom of the storage box 2 is provided with a cylindrical cavity, the cylindrical cavity is provided with a discharge port, the material fixing component includes a rotating shaft 7, the rotating shaft 7 is rotatably connected in the cylindrical cavity, and a plurality of dial wheels 701 are fixedly connected to the rotating shaft 7.

[0024] In practice, the rotating shaft 7 and the dial wheel 701 can not only feed the seeds quantitatively, but also break up the damp and clumped grass seeds. The fixed receiving cavity formed by multiple dial wheels 701 can ensure that the amount of seeds fed each time is consistent, thereby improving the uniformity of grass seed sowing.

[0025] Please see Figure 5 The present invention provides a technical solution: the second motor 11 is disposed below the material distribution plate 4 and its output end is fixedly connected to the material distribution plate 4. The output end of the second motor 11 is provided with a gearbox, and the second motor 11 drives the rotating shaft 7 to rotate through the gearbox.

[0026] In specific implementation: The gearbox is composed of multiple sets of bevel gears, which transmit the power of the second motor 11 to the rotating shaft 7. The gearbox drives the rotating shaft 7 and the material distribution plate 4 synchronously. While the material distribution plate 4 accelerates its rotation, the rotating shaft 7 accelerates its rotation synchronously, so that the feeding speed and the spreading speed are synchronized, avoiding material blockage.

[0027] The second motor 11 can simultaneously drive the distributing disc 4 and the rotating shaft 7 to rotate, so that the distributing disc 4 scatters grass seeds, and the rotating shaft 7 further drives the dial wheel 701 to rotate, thereby evenly and quantitatively bringing the material in the storage box 2 into the feeding hopper 5 and the distributing disc 4. The space formed between the two dial wheels 701 has a fixed volume, so it can be ensured that the amount of material discharged each time is fixed. In addition, the driving mechanism 8 can also control the feeding speed. To speed up the feeding speed, simply increase the speed of the motor 81. At the same time, the driving mechanism 8 can also keep the distributing speed of the distributing disc 4 and the feeding speed of the dial wheel 701 synchronized, preventing grass seeds from accumulating on the surface of the distributing disc 4 due to excessive feeding speed.

[0028] Please see Figure 4 The present invention provides a technical solution: the endpoints of the cross rod 65 are rotatably connected to the first arc-shaped seat 63 and the second arc-shaped seat 64 respectively, and the top of the storage box 2 is provided with a feed inlet 201.

[0029] In specific implementation: the first arc-shaped seat 63 and the second arc-shaped seat 64 are connected by the cross rod 65, and both the first arc-shaped seat 63 and the second arc-shaped seat 64 are rotatably connected to the cross rod 65, so that the first arc-shaped seat 63 and the second arc-shaped seat 64 can rotate relative to each other, thereby allowing the storage box 2 to rotate in any position within the UAV body 1 until it remains vertically downward under the action of gravity.

[0030] Please see Figure 5 The present invention provides a technical solution: the feeding hopper 5 is located below the dial wheel 701, the feeding hopper 5 and the sealing cover 3 are fixedly connected, and the sealing cover 3 and the distributing plate 4 are rotatably connected.

[0031] In practice: the dial wheel 701 conveys grass seeds into the feed hopper 5, and the dial wheel 701 can also break up the damp and clump-like grass seeds, thereby preventing the grass seeds from clogging the discharge port. The grass seeds finally fall onto the distribution plate 4 through the feed hopper 5.

[0032] Please see Figure 6 The present invention provides a technical solution: the sealing cover 3 has a circular hole 302, the circular hole 302 is connected to the feed hopper 5, and the side wall of the sealing cover 3 has an arc-shaped opening 301.

[0033] In specific implementation: the round hole 302 is used to let the grass seeds in the feed hopper 5 fall onto the distribution plate 4, and the arc-shaped opening 301 is used to throw out the grass seeds through the centrifugal rotation of the distribution plate 4.

[0034] Example 2: Please see Figure 3 Based on the above embodiments: a discharge port 104 is provided on the outer wall of the storage box 2. The arc-shaped opening 301 cooperates with the discharge port 104. A windproof mechanism 8 is installed on the discharge port 104. The windproof mechanism 8 includes a mounting base 88. Two mounting bases 88 are fixedly connected to the storage box 2 and located above the discharge port 104. A roller 86 is rotatably connected to the two mounting bases 88. An upper baffle 81 is wound on the roller 86. Side baffles 82 are connected to both sides of the upper baffle 81. A connecting base 89 is fixedly connected to the mounting base 88. A rotating rod 87 is rotatably connected to the connecting base 89. An mounting plate 801 is rotatably connected to the end of the rotating rod 87 away from the connecting base 89. The upper baffle 81 is connected to the mounting plate 801. The side baffles 82 are connected to the upper baffle 81 at multiple points, so that they can be extended and folded.

[0035] In practice: when grass seeds are thrown out of the discharge port 104, the upper baffle 81 and the side baffle 82 can guide the grass seeds to prevent them from being scattered by the wind. The upper baffle 81 and the side baffle 82 can be unfolded and folded. When sowing, the upper baffle 81 and the side baffle 82 are unfolded to reduce the impact of the wind. When not in use, the upper baffle 81 and the side baffle 82 are folded.

[0036] Please see Figure 2-3 As shown, a worm gear 85 is fixedly connected to the end of the reel 86. The worm gear 85 is rotatably connected to the mounting base 88. A first motor 83 is installed in the storage box 2. A worm 84 is fixedly connected to the output end of the first motor 83. The worm 84 and the worm gear 85 mesh.

[0037] In specific implementation: The working principle of the windproof mechanism 8 is as follows: by starting the first motor 83, the worm gear 84 is driven to rotate, the worm gear 84 drives the meshing worm wheel 85 to rotate, and the worm wheel 85 drives the roller 86 to rotate, thereby releasing the upper baffle 81 from the roller 86. The mounting plate 801 moves downward under the action of gravity, driving the rotating rod 87 to rotate and unfold around the connecting seat 89. After the upper baffle 81 is fully released, the side baffles 82 on both sides are unfolded simultaneously, forming a windproof channel covering the outside of the discharge port 104 to guide the thrown grass seeds. When rewinding, the first motor 83 rotates in the opposite direction, driving the roller 86 to rotate in the opposite direction, rewinding the upper baffle 81, pulling the mounting plate 801 upward, driving the rotating rod 87 to fold and retract, completing the overall retraction of the windproof mechanism without affecting the storage of the device.

[0038] Please see Figure 3 The present invention provides a technical solution: a mounting frame 9 is fixedly connected to the storage box 2, the second motor 11 is fixed on the mounting frame 9, and a support frame 10 is also fixedly connected to the storage box 2. The support frame 10 is used to fix the sealing cover 3 and the second motor 11.

[0039] In practice: the mounting frame 9 and the support frame 10 connect the storage box 2, the sealing cover 3 and the distribution plate 4 into a whole.

[0040] Please see Figure 2 The present invention provides a technical solution: landing gear 101 is installed on the front and rear sides of the UAV body 1, and a set of connecting rods 102 is provided on the left and right sides of the UAV body 1. The number of connecting rods 102 in each set is two, and the end of the connecting rod 102 is equipped with a wing 103.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
