DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] The following is further described in conjunction with specific embodiments. Figure 1-Figure 8 As shown, the present invention is a grass seed spraying device for landscaping, including a frame 1, the frame 1 including a bottom plate 10, a column 12 and a fixing tube 11, the bottom plate 10 is fixedly mounted on a carrier body 8 by bolts, and the carrier body 8 can be a transport vehicle such as a car or a tractor according to the use requirements. Through the stable fixation of the bottom plate 10, the reliable installation of the entire device on the carrier body 8 is achieved, providing a basic guarantee for subsequent operations. The fixing tube 11 and the snake tube 2 are connected to the frame 1 by a movable connection, so that one end of the snake tube 2 extends out of the frame 1, ensuring its flexibility and operating range during operation.

[0022] The snake tube 2 is composed of a plurality of joints 21 hinged to each other, and the plurality of joints 21 together form an integrated hollow tubular structure, so that the entire snake tube 2 has good flexibility and bendability. It should be noted that the end of the snake tube 2 close to the carrier body 8 is the proximal end, and the end away from the carrier body 8 is the distal end. The snake tube 2 can be bent in the vertical direction through the action of the driving component 5, and fixed to the target position after bending, so as to adapt to the complex changes of the garden terrain, such as bending downward, protruding upward or flat terrain, to meet the needs of grass seed spraying in various scenarios. This structural design significantly improves the adaptability of the device under complex terrain.

[0023] The feed hose 3 is inserted into the multiple joints 21 of the snake tube 2. The distal end of the feed hose 3 is closed and provides a channel for the delivery of grass seeds. The feed hose 3 is provided with multiple discharge nozzles 33, which are evenly distributed at a specific interval. The discharge nozzles 33 are located outside the joints 21 of the snake tube 2, and the outlet ends are arranged facing the ground. The discharge nozzles 33 are designed to be flat and long. This shape can effectively expand the coverage of grass seed spraying and ensure 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 is used to store grass seeds and transport the grass seeds to the discharge nozzle 33 through the feeding hose 3. Through the optimized feeding design, grass seeds can be continuously and stably transported to the feeding hose 3 to ensure the continuity and efficiency of the spraying process.

[0025] The driving assembly 5 is responsible for driving the multiple joints 21 of the snake tube 2 to perform synchronous bending adjustment. Through the precise control of the driving assembly 5, the snake tube 2 can flexibly adjust the bending angle according to the actual terrain conditions, and firmly fix it after reaching the target position. This dynamic adjustment mechanism enables the snake 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, in order to achieve the sliding adjustment of the snake tube 2 in the horizontal direction, the snake tube 2 is slidably installed on the fixed tube 11. A pair of first cylinders 111 are installed on the fixed tube 11. The first cylinder 111 is a multi-stage cylinder design, which can not only increase the driving distance of the cylinder, but also effectively reduce the length of the cylinder itself, thereby avoiding the space occupation and inconvenience of operation caused by the cylinder being too long. This design allows the cylinder to achieve a larger range of activities and a more precise adjustment effect in a limited space.

[0027] The proximal end of the serpentine tube 2 is fixedly connected to a fixing plate 22, and a through hole 221 is opened on the fixing plate 22 for the feeding hose 3 to pass through. The piston rod of the first cylinder 111 is fixedly connected to the fixing plate 22, and four limiting rods 7 are passed through the fixing tube 11. The multiple limiting rods 7 are evenly arranged around the serpentine tube 2 and are used to limit the bending of the serpentine tube 2 in the area of ​​the limiting rods 7. The multiple limiting rods 7 are fixedly connected to the fixing plate 22 at the same time.

[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 as a whole can be prefabricated in a factory, the first feeding assembly 41 is connected to the first channel 31, the second feeding assembly 42 is connected to the second channel 32, the discharge nozzles 33 are respectively located on both sides of the snake tube 2 in the horizontal direction, and the discharge nozzles 33 on both sides are respectively connected to the first channel 31 and the second channel 32, the second feeding assembly 42 is used to store and transport covering materials to the second channel 32, the covering materials can be soil or fiber fragments, etc., and the soil or fiber fragments can be stirred with water to be wet materials for spraying, so as to prevent the spraying from being affected by wind, improve the covering effect, and improve the germination rate and survival rate of grass seeds. By spraying wet materials, not only the stability of the covering layer can be enhanced, but also the covering materials can be effectively prevented from being over-dried and lost, further improving the spraying effect. It should be emphasized that the first channel 31 for conveying grass seeds and the corresponding discharge nozzle 33 need to be located in front of the carrier body 8, while the second channel 32 for conveying covering material and the corresponding discharge nozzle 33 need to be located at the rear of the carrier body 8. Through such a layout design, it is ensured that the grass seeds are first sown on the ground, and the covering material follows closely and accurately covers the grass seeds, thereby protecting the grass seeds, avoiding exposure of the grass seeds to the external environment in the early stage, and providing the best growth conditions.

[0029] Among them, the first feeding component 41 and the second feeding component 42 both include a storage box 412, a feeding pump 413 and a feeding hose 414. The storage boxes 412 of the first feeding component 41 and the second feeding component 42 are fixed on the base plate 10 by bolts, and the feeding pump 413 is installed on the feeding hose 414. The feeding pump 413 can be a vacuum pump. The feeding hoses 414 of the first feeding component 41 and the second feeding component 42 are respectively connected to the first channel 31 and the second channel 32. Specifically, the feeding hoses 414 of the first feeding component 41 and the second feeding component 42 are connected to the proximal end of the feeding hose 414 through the main joint 331. The main joint 331 also has two channels and is correspondingly connected to the first channel 31 and the second channel 32 of the feeding hose 414. After starting the corresponding feeding pump 413, the feeding hoses 414 of the first feeding assembly 41 and the second feeding assembly 42 can be fed, and then the first channel 31 and the second channel 32 can be fed, and finally the grass seeds and mulch materials can be sprayed.

[0030] Reference Figure 5 and Figure 6 As shown, the driving assembly 5 includes a pair of traction ropes 51, a pair of traction wheels 52 and a driving component 53. The pair of traction ropes 51 need to be made of steel wire ropes. The pair of traction ropes 51 are respectively 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 simultaneously connected to the distal ends of the snake bone tube 2. Limiting rings 211 are fixedly welded on both sides of the inner side of each bone joint 21 along the radial direction. The traction rope 51 passes through the limiting ring 211. The limiting ring 211 limits the traction rope 51 to prevent the traction rope 51 from shifting when being pulled. The pair of traction wheels 52 are respectively rotatably installed 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 correspondingly wound around the pair of traction wheels 52. The driving component 53 is used to drive the pair of traction wheels 52 to rotate synchronously to release one of the traction ropes 51 and tighten the other traction rope 51.

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

[0032] Reference Figure 1 and Figure 8As shown, the column 12 is fixedly installed on the base plate 10, and a pair of columns 12 are provided. A sliding plate 13 is slidably provided on the pair of columns 12 along the vertical direction. A rodless cylinder 131 is fixedly installed vertically on the pair of columns 12. 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 stopping the rodless cylinder 131. A sliding rail 132 is fixedly installed vertically on the column 12, and a slider 133 is fixedly welded on the sliding plate 13. The slider 133 is slidably clamped on the sliding rail 132.

[0033] Reference Figure 3 and Figure 4 As shown, a rotating seat 14 is rotatably arranged on the sliding plate 13. The rotating seat 14 is in a truncated cone shape. The rotation center line of the rotating seat 14 is arranged vertically. A rotating component 15 is installed on the sliding plate 13 for driving the rotating seat 14 to rotate and fix it to the rotated position.

[0034] The rotating component 15 includes a gear ring 151, a gear 152 and a rotating motor 153, wherein the gear ring 151 is fixedly sleeved on the rotating seat 14, the rotating motor 153 is fixedly mounted on the support seat 154, the support seat 154 is fixedly mounted on the sliding plate 13, the gear 152 is coaxially fixedly mounted on the output shaft of the rotating motor 153, the gear 152 and the gear ring 151 are meshed with each other, and the rotating motor 153 drives the gear 152 to rotate, which can drive the gear ring 151 and the rotating seat 14 to rotate, thereby realizing the rotation adjustment of the snake tube 2 in the vertical direction, improving the range of grass seed spraying and the adaptability of the entire device. It should be noted that in this embodiment, the rotating motor 153 uses a self-locking motor. The self-locking motor has a unique structural feature. When the motor stops rotating, the internal structure of the motor will automatically lock, so that the position of the rotating seat 14 can be fixed. This design can effectively prevent the position drift of the rotating seat 14 due to inertia or external force after the rotating motor 153 stops, thereby ensuring that the snake tube 2 can stably maintain the set angle and position during the spraying process. This self-locking mechanism improves the safety and accuracy of the device, ensures the uniformity and accuracy of grass seed spraying, and also avoids possible failures and unnecessary adjustments caused by unstable device position.

[0035] A swing seat 16 is fixedly installed on the rotating seat 14, and rotating shafts 112 are fixedly welded on both sides of the fixed cylinder 11 in the horizontal direction. The rotating shaft 112 is rotatably passed through the swing seat 16. A driving member 6 is also provided on the swing seat 16. The driving member 6 is used to drive the rotating shaft 112 to drive the fixed cylinder 11 to rotate and fix it to the rotated position.

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

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

The discharge nozzles 33 pass through the side openings 212 and are threadedly connected with the connecting pipe heads 34 to achieve a detachable connection of the discharge nozzles 33. When the discharge nozzles 33 are installed, the discharge nozzles 33 on both sides of the feeding hose 3 can be staggered. The position of the connecting pipe heads 34 where the discharge nozzles 33 are not installed can be threadedly connected to the sealing cover 341 to achieve the closure of the connecting pipe heads 34 at that position. This design improves the flexibility of the equipment, and it can flexibly choose whether to use all the discharge nozzles 33 according to actual needs, thereby optimizing the grass seed spraying effect and the service life of the device.
