[0001] This invention relates to the field of seeding equipment technology, and more specifically, to a grass seed spraying device for landscaping. Background Technology

[0002] In landscaping, sowing grass seeds is a crucial step in ensuring plant growth and aesthetic appeal. Traditional seeders are typically designed for use on level ground, working by evenly spreading grass seeds across the soil surface using a rotating seeding wheel or nozzle. This type of equipment performs well on flat, regular surfaces, quickly and accurately completing the seeding task.

[0003] However, existing seeding equipment often suffers from insufficient adaptability when dealing with different terrains, especially garden surfaces that curve downwards or jut upwards.

This invention, by mounting a frame on a transport vehicle and adapting to the specific terrain features of the garden (such as downward curves, upward protrusions, or level ground), utilizes a drive assembly to control multiple segments of the snake-bone tube to achieve unidirectional bending. This allows the snake-bone tube to be flexibly adjusted and fixed in place vertically, thus adapting to the needs of different terrains. Simultaneously, a first feeding assembly stores grass seeds, which are then transported to a discharge nozzle and sprayed onto the ground via a feeding hose, achieving efficient and uniform sowing.

Detailed Implementation

[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 embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0021] The following description, in conjunction with specific embodiments, provides further details. Figures 1-8 As shown, this invention is a grass seed spraying device for landscaping, comprising a frame 1. The frame 1 includes a base plate 10, a column 12, and a fixing cylinder 11. The base plate 10 is fixedly mounted on a transport vehicle 8 by bolts. The transport vehicle 8 can be a car, tractor, or other transport vehicle according to usage requirements. The stable fixing of the base plate 10 ensures reliable installation of the entire device on the transport vehicle 8, providing a basic guarantee for subsequent operations. The fixing cylinder 11 and the snake-bone tube 2 are movably connected, allowing one end of the snake-bone tube 2 to extend beyond the frame 1, ensuring its flexibility and operating range during operation.

[0022] The snake-bone tube 2 is composed of multiple hinged segments 21, which together form an integrated hollow tubular structure, giving the entire snake-bone tube 2 excellent flexibility and bendability. It should be noted that the end of the snake-bone tube 2 closest to the transport vehicle body 8 is the proximal end, and the end furthest from the transport vehicle body 8 is the distal end. The snake-bone tube 2 can bend vertically through the drive component 5 and then be fixed to the target position, adapting to complex changes in garden terrain, such as downward bends, upward protrusions, or flat terrain, meeting the needs of grass seed spraying in various scenarios. This structural design significantly improves the device's adaptability to complex terrain.

[0023] The feeding hose 3 passes through multiple joints 21 of the snake-bone pipe 2. The distal end of the feeding hose 3 is closed, providing a channel for grass seed delivery. Multiple discharge nozzles 33 are installed on the feeding hose 3, evenly distributed at specific intervals. The discharge nozzles 33 are located outside the joints 21 of the snake-bone pipe 2, with their outlets facing the ground. The discharge nozzles 33 are designed as flat, elongated strips. This shape effectively expands the coverage area of ​​the grass seed spraying and ensures that the grass seeds are evenly distributed on the ground, thereby improving the spraying effect and reducing grass seed waste.

[0024] The first feeding assembly 41 stores grass seeds and transports them to the discharge nozzle 33 via the feeding hose 3. Through optimized feeding design, grass seeds can be continuously and stably supplied to the feeding hose 3, ensuring the continuity and efficiency of the spraying process.

[0025] The drive assembly 5 is responsible for driving the multiple joints 21 of the snake-bone tube 2 to bend and adjust synchronously. Through the precise control of the drive assembly 5, the snake-bone tube 2 can flexibly adjust the bending angle according to the undulations of the actual terrain and be firmly fixed after reaching the target position. This dynamic adjustment mechanism enables the snake-bone tube 2 to fully adapt to various complex terrains in the garden and achieve precise grass seed spraying operations.

[0026] Reference Figure 2 and Figure 3 As shown, to achieve horizontal sliding adjustment of the snake-bone tube 2, the snake-bone tube 2 is slidably mounted on the fixed cylinder 11. A pair of first cylinders 111 are installed on the fixed cylinder 11. These first cylinders 111 are multi-stage cylinders, which not only increases the cylinder's driving distance but also effectively reduces the cylinder's length, thus avoiding the space occupation and operational inconvenience caused by excessively long cylinders. This design allows the cylinders to achieve a greater range of motion and more precise adjustment within a limited space.

[0027] A fixing plate 22 is fixedly connected to the proximal end of the snake tube 2. The fixing plate 22 has a through hole 221 for the feeding hose 3 to pass through. The piston rod of the first cylinder 111 is fixedly connected to the fixing plate 22. Four limiting rods 7 are provided on the fixing cylinder 11. The multiple limiting rods 7 are evenly arranged around the snake tube 2 to limit the bending of the snake tube 2 in the area of ​​the limiting rods 7. The multiple limiting rods 7 are simultaneously fixedly connected to the fixing plate 22.

[0028] Reference Figure 2 and Figure 5 As shown, the present invention also includes a second feeding assembly 42. The feeding hose 3 is divided into a first channel 31 and a second channel 32 along its axial direction by a partition 30. The feeding hose 3 and the partition 30 can be prefabricated in the factory. The first feeding assembly 41 is connected to the first channel 31, and the second feeding assembly 42 is connected to the second channel 32. The discharge nozzles 33 are located on both sides of the snake-bone tube 2 in the horizontal direction, and the discharge nozzles 33 on both sides are connected to the first channel 31 and the second channel 32 respectively. The second feeding assembly 42 is used to store and transport the covering material to the second channel 32. The covering material can be soil or fiber fragments, etc. At the same time, the soil or fiber fragments can be mixed with water to form a wet material for spraying, so as to prevent the spraying from being affected by the wind, improve the covering effect, and increase the germination rate and survival rate of grass seeds. By spraying the wet material, not only can the stability of the covering layer be enhanced, but the excessive drying and loss of the covering material can also be effectively prevented, further improving the spraying effect. It is important to emphasize that the first channel 31 for conveying grass seeds and the corresponding discharge nozzle 33 must be located in front of the transport vehicle body 8, while the second channel 32 for conveying covering material and the corresponding discharge nozzle 33 must be located behind the transport vehicle body 8. This layout design ensures that the grass seeds are first sown on the ground, and the covering material follows closely behind, accurately covering the grass seeds, thereby protecting the grass seeds, preventing them from being exposed to the external environment in the early stages, and providing optimal growth conditions.

[0029] The first feeding assembly 41 and the second feeding assembly 42 each include a storage tank 412, a feeding pump 413, and a conveying hose 414. The storage tank 412 of each of the first feeding assembly 41 and the second feeding assembly 42 is fixedly installed on the base plate 10 by bolts. The feeding pump 413 is installed on the conveying hose 414. The feeding pump 413 can be a vacuum pump. The conveying hose 414 of each of the first feeding assembly 41 and the second feeding assembly 42 is respectively connected to the first channel 31 and the second channel 32. Specifically, the conveying hose 414 of each of the first feeding assembly 41 and the second feeding assembly 42 is connected to the near end of the conveying hose 414 through a main connector 331. The main connector 331 also has two channels and is connected to the first channel 31 and the second channel 32 of the conveying hose 414. After the corresponding feeding pump 413 is started, the feeding hoses 414 of the first feeding component 41 and the second feeding component 42 can be fed, thereby feeding the first channel 31 and the second channel 32, and finally spraying grass seeds and covering material.

[0030] Reference Figure 5 and Figure 6 As shown, the drive assembly 5 includes a pair of traction ropes 51, a pair of traction wheels 52, and a drive component 53. Both traction ropes 51 are made of steel wire rope. The pair of traction ropes 51 are located on the upper and lower sides of the snake bone tube 2 along its radial direction. The distal ends of the pair of traction ropes 51 are connected to the distal ends of the snake bone tube 2. Limiting rings 211 are fixedly welded to both sides of the inner side of each bone segment 21 along its radial direction. The traction ropes 51 are set through the limiting rings 211. The limiting rings 211 limit the traction ropes 51 and prevent the traction ropes 51 from shifting when pulled. The pair of traction wheels 52 are rotatably mounted on the side plates 222. The side plates 222 are fixedly welded to the fixing plate 22. The pair of traction ropes 51 are respectively wound around the pair of traction wheels 52. The drive component 53 is used to drive the pair of traction wheels 52 to rotate synchronously to release one of the traction ropes 51 and tension the other traction rope 51.

[0031] Reference Figure 5 As shown, the drive component 53 includes a pair of pulleys 531, a toothed belt 532, and a drive member 6. The pair of pulleys 531 are coaxially and fixedly connected to a pair of traction wheels 52. The toothed belt 532 is wound around the pair of pulleys 531. The drive member 6 is used to drive one of the pulleys 531 to rotate and fix it to the rotated position. In other embodiments, the configuration of pulleys 531 and toothed belt 532 can be replaced by a pair of sprockets and a chain. By adopting a chain drive system, the stability and durability of the transmission can be improved. Especially in more complex and high-load working environments, the chain system can provide stronger tensile strength and a longer service life.

[0032] Reference Figure 1 and Figure 8As shown, the column 12 is fixedly installed on the base plate 10. There is a pair of columns 12. Each pair of columns 12 has a sliding plate 13 that slides vertically. Each pair of columns 12 has a rodless cylinder 131 fixedly installed vertically. The output end of the rodless cylinder 131 is fixedly connected to the sliding plate 13. The vertical position of the sliding plate 13 is adjusted by the rodless cylinder 131. Since the rodless cylinder 131 has a self-locking function, the position of the sliding plate 13 can be fixed after the rodless cylinder 131 is stopped. A slide rail 132 is fixedly installed vertically on the column 12. A slider 133 is fixedly welded on the sliding plate 13. The slider 133 is slidably engaged with the slide rail 132.

[0033] Reference Figure 3 and Figure 4 As shown, a rotating seat 14 is rotatably mounted on the sliding plate 13. The rotating seat 14 is frustum-shaped and the rotation center line of the rotating seat 14 is vertically arranged. A rotating component 15 is installed on the sliding plate 13 to drive the rotating seat 14 to rotate and fix it to the position after rotation.

[0034] The rotating component 15 includes a gear ring 151, a gear 152, and a rotating motor 153. The gear ring 151 is fixedly sleeved on the rotating seat 14, and the rotating motor 153 is fixedly mounted on a support seat 154, which is fixedly mounted on a sliding plate 13. The gear 152 is coaxially fixedly mounted on the output shaft of the rotating motor 153. The gear 152 meshes with the gear ring 151. By driving the gear 152 to rotate through the rotating motor 153, the gear ring 151 and the rotating seat 14 can be driven to rotate, thereby achieving vertical rotation adjustment of the snake-bone tube 2, improving the range of grass seed spraying and the adaptability of the entire device. It should be noted that in this embodiment, a self-locking motor is used for the rotating motor 153. A self-locking motor has unique structural features; when the motor stops rotating, its internal structure automatically locks, fixing the position of the rotating seat 14. This design effectively prevents the rotating seat 14 from drifting due to inertia or external force after the rotating motor 153 stops, thus ensuring that the snake-bone tube 2 can be stably maintained at the set angle and position during the spraying process. This self-locking mechanism improves the safety and accuracy of the device, ensuring the uniformity and accuracy of grass seed spraying, while also avoiding malfunctions and unnecessary adjustments that may be caused by unstable device position.

[0035] A swing seat 16 is fixedly installed on the rotating seat 14. A rotating shaft 112 is fixedly welded to both sides of the fixed cylinder 11 in the horizontal direction. The rotating shaft 112 rotates through the swing seat 16. A driving component 6 is also provided on the swing seat 16. The driving component 6 is used to drive the rotating shaft 112 to drive the fixed cylinder 11 to rotate and fix it to the position after rotation.

[0036] Reference Figure 4As shown, the driving components 6 on the swing seat 16 and the side plate 222 each include a worm gear 61, a worm 62, and a drive motor 63. The worm gear 61 on the swing seat 16 and the worm 62 on the side plate 222 mesh with each other. The output shaft of the drive motor 63 is coaxially and fixedly connected to the worm 62 to drive the worm 62 to rotate, thereby driving the worm gear 61 to rotate. Since the worm gear 61 and the worm 62 have a self-locking function, after the drive motor 63 stops rotating, the rotation position of the fixed cylinder 11 along the rotation axis 112 and the bending position of the snake tube 2 can be fixed. In order to protect the worm gear 61 and the worm 62, a protective cover 64 is provided on the outside of the worm gear 61 and the worm 62. The drive motor 63 is installed outside the protective cover 64 or inside the protective cover 64. In this embodiment, the drive motor 63 is installed outside the protective cover 64, and the output shaft of the drive motor 63 passes through the inside of the protective cover 64 and is coaxially and fixedly connected to the worm 62. The drive motor 63 can be a waterproof motor.

[0037] Reference Figure 3 and Figure 4 As shown, an end ring 72 is fixedly connected to one end of multiple limiting rods 7 away from the fixing plate 22. The end ring 72 is arranged in a ring shape and is sleeved on the snake bone tube 2. A limiting screw 721 is threaded through the end ring 72. Multiple limiting screws 721 can be provided to improve the fixing effect. The limiting screw 721 is used to abut against the joint 21 to limit the position of the end ring 72. At the same time, the limiting rod 7 is telescopic. Specifically, the limiting rod 7 is composed of multiple tubes 71 that slide and insert into each other to facilitate the telescopic movement of the limiting rod 7.

[0038] Reference Figure 6 and Figure 7 As shown, connecting pipe heads 34 are connected to both sides of the feeding hose 3. Side openings 212 are provided on both sides of the joint 21. The connecting pipe heads 34 are positioned directly opposite the side openings 212. The discharge nozzles 33 pass through the side openings 212 and are threadedly connected to the connecting pipe heads 34 to achieve a detachable connection of the discharge nozzles 33. When installing the discharge nozzles 33, the discharge nozzles 33 on both sides of the feeding hose 3 can be staggered. The position of the connecting pipe head 34 where the discharge nozzle 33 is not installed can be threaded with a sealing cap 341 to seal the connecting pipe head 34 at that position. This design improves the flexibility of the equipment, allowing for flexible selection of whether to use all discharge nozzles 33 according to actual needs, thus optimizing the grass seed spraying effect and the service life of the device.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
