Description

Technical Field

[0001] This utility model relates to the field of landscaping construction and technology, and more specifically, it relates to a spraying device for landscaping construction. Background Technology

[0002] In modern landscaping construction, spraying is an important part of preventing and controlling pests and diseases and protecting plant growth. However, the spraying devices commonly available on the market have obvious limitations in use. Due to the single fixing method of the nozzles, it is impossible to flexibly adjust the spraying range according to the growth height and distribution density of different plants, resulting in uneven spraying of pesticides, which not only wastes pesticides but also affects the control effect, and cannot meet the actual needs of precise spraying in landscaping construction.

[0003] In the daily maintenance of landscaping, different types of pesticides or fertilizers are often required for different seasons and different plants. This necessitates the frequent replacement of nozzles of different specifications. However, most existing spraying devices use traditional threaded connections or snap-fit ​​fixing methods. Replacing nozzles not only requires the use of professional tools, but also involves cumbersome and time-consuming operations. This design not only reduces work efficiency, but also easily damages nozzles due to improper operation, increasing maintenance costs and seriously affecting the progress and quality of landscaping construction.

[0029] Please see Figures 1-5A spraying device for landscaping construction includes a drone 1. A spraying mechanism is installed below the drone 1. The spraying mechanism includes a support frame 2, a pesticide storage tank 3, a water pump 4, a diversion pipe 5, a fixed frame 6, a support plate 7, and nozzles 8. The support frame 2 is installed on the bottom of the drone 1. The pesticide storage tank 3 is located inside the support frame 2. The water pump 4 is connected to the outside of the pesticide storage tank. The diversion pipe 5 is connected to the output end of the water pump 4. The fixed frame 6 is installed on the support frame 2. Two sets of nozzles are connected to the support plate 7. Multiple sets of nozzles 8 are connected to the diversion pipe 5 via quick-connect mechanisms. The quick-connect mechanisms include a quick-connect sleeve 9, a screw sleeve 10, a screw 11, a pinion 12, a linkage rod 13, and a clamp. The system includes a plate 14, a tube 15, a slanted groove 16, a sliding sleeve 17, a small rack 18, and a fastening mechanism. The quick-release sleeve 9 is fixed on the support plate 7. Multiple sets of threaded sleeves 10 are fixed to the outer wall of the quick-release sleeve 9. The screw 11 is connected to the multiple sets of threaded sleeves 10. The small gear 12 rotates at the top of the multiple sets of threaded sleeves 10. The linkage rod 13 is fixed to the top of the multiple sets of screws 11 and is slidably connected to the multiple sets of gears. The clamping plate 14 rotates at the bottom of the multiple sets of screws 11. The insert rod is fixed to the top of the nozzle 8 and inserted into the quick-release sleeve 9. The slanted groove 16 is provided on the outer wall of the tube 15. The sliding sleeve 17 slides on the outer wall of the quick-release sleeve 9. Multiple sets of small racks 18 are distributed on the outer wall of the sliding sleeve 17 and mesh with the multiple sets of small gears 12.

[0030] The fastening mechanism includes a fastening sleeve 19, a rotating sleeve 20, a limiting sleeve 21, a support rod 22, a stop block 23, an arc-shaped groove 24, and a clearance groove 25. The fastening sleeve 19 slides on the outer wall of the quick-release sleeve 9, the rotating sleeve 20 rotates on the outer wall of the quick-release sleeve 9, the limiting sleeve 21 is fixed to the bottom surface of the rotating sleeve 20, multiple sets of support rods 22 are distributed on the top surface of the fastening sleeve 19, the stop block 23 is installed on the top of the multiple sets of support rods 22, multiple sets of arc-shaped grooves 24 are distributed on the limiting sleeve 21, and the clearance groove 25 is located at one end of the multiple sets of arc-shaped grooves 24. When the rotating sleeve 20 rotates, the limiting sleeve 21 drives the arc-shaped groove 24 to move, so that the stop block 23 enters the arc-shaped groove 24 from the clearance groove 25, thereby realizing the locking function.

[0031] The fixed frame 6 is equipped with a folding mechanism, which includes a large gear 26, a large rack 27 and a cylinder 28. The large gear 26 is installed at the bottom of the two sets of support rods and is rotatably connected to the fixed frame 6. The large rack 27 has teeth on both sides and meshes with the two sets of large gears 26 respectively. The cylinder 28 is fixed in the fixed frame 6 and its telescopic end is connected to the large rack 27. The cylinder 28 pushes the large rack 27 to move, and the two sets of large gears 26 rotate synchronously through the gear and rack transmission, thereby driving the support rods to fold.

[0032] The diversion tube 5 is made of flexible tubing. The flexible tubing 5 can deform freely with the folding movement of the support rod, ensuring that the delivery of the medicine is not affected.

[0033] The quick-release sleeve 9 has a movable groove 29, and both ends of the multiple sets of clamping plates 14 slide within the movable groove 29. The movable groove 29 provides a movement track for the clamping plates 14, ensuring that the clamping plates 14 move along a predetermined path.

[0034] The quick-release sleeve 9 has a sealing gasket 30 inside, and the top of the insertion tube 15 has a sealing ring 31. The bottom of the sealing gasket 30 has a sealing groove that matches the sealing ring 31. When the sealing ring 31 is pressed into the sealing groove, it will compress the sealing gasket 30, forming a double sealing structure.

[0035] Multiple sets of connecting rods are all set as polygons and are slidably connected to multiple sets of pinions 12. The polygonal connecting rods and the pinions 12 form a large contact surface, which improves the reliability of the transmission.

[0036] Multiple sets of support rods 22 are provided with push springs 32 on their outer sides. The bottom ends of the multiple sets of push springs 32 are fixedly connected to fastening sleeves 19 and the top ends are in contact with limiting sleeves 21. The push springs 32 provide pre-tightening force for the support rods 22, so that the abutment block 23 always remains in contact with the limiting sleeve 21.

[0037] In this embodiment, the drone 1 lifts the device, starts the water pump 4 to transport the medicine in the medicine storage tank 3 to the diversion pipe 5, and then delivers it to the nozzle 8 through the insertion tube 15 for spraying. When it is necessary to gather the nozzles 8 together, the cylinder 28 is operated to retract its telescopic end, pulling the large rack 27 to mesh with the two sets of large gears 26, causing the two sets of large gears 26 to rotate inwards simultaneously and drive the two sets of support plates 7 to rotate and fit together. At this time, the two sets of support plates 7 drive multiple sets of nozzles 8 to gather together for concentrated spraying. When it is necessary to replace the nozzles 8, the rotating sleeve 20 is rotated to drive the limiting sleeve 21 to rotate, and the limiting sleeve 21 drives multiple sets of clearance grooves 25 to move to the maximum position. At the top of the abutment block 23, the multiple abutments release their contact with the limiting sleeve 21. Then, the fastening sleeve 19 can be pushed to slide and release the abutment of the sliding sleeve 17 and compress the multiple push springs 32. At the same time, the sliding sleeve 17 drives the multiple small racks 18 to mesh with the multiple small gears 12. The multiple small gears 12 drive the multiple connecting rods and screws 11 to rotate, so that the multiple screws 11 engage with the multiple screw sleeves 10 and pull the multiple clamping plates 14 to slide outward along the movable groove 29, so that the multiple clamping plates 14 are released from the clamping of the inclined groove 16. Then, the insertion tube 15 on the nozzle 8 can be pulled out of the quick-release sleeve 9, completing the quick disassembly of the nozzle 8.

[0038] More specifically, when the nozzle 8 needs to be installed, the insertion tube 15 is inserted into the quick-release sleeve 9, and the sealing end is engaged in the sealing groove at the bottom of the sealing gasket 30, and the sealing gasket 30 is squeezed. Multiple sets of push springs 32 push the fastening sleeve 19 and the sliding sleeve 17 to move. The sliding sleeve 17 is driven by multiple sets of small racks 18 meshing with multiple sets of small gears 12, so that multiple sets of screws 11 are threaded along the screw sleeve 10, thereby pushing the clamping plate 14 to clamp in the inclined groove 16 to hold the insertion tube 15. Then, multiple sets of abutments 23 disengage from the relief groove 25, and the rotating sleeve 20 drives the limiting sleeve 21 to rotate, so that multiple sets of abutments 23 abut against the outer wall of the limiting sleeve 21, and the sliding sleeve 17 is pressed, thus completing the fixing of the nozzle 8.

[0039] In summary, during the use or operation of the overall equipment: the drone 1 lifts the device, starts the water pump 4 to transport the medicine in the medicine storage tank 3 to the diversion pipe 5, and then delivers it to the nozzle 8 through the insertion pipe 15 for spraying. When it is necessary to gather the nozzles 8 together, the control cylinder 28 retracts its telescopic end, pulling the large rack 27 to mesh with the two sets of large gears 26, causing the two sets of large gears 26 to rotate inwards simultaneously and drive the two sets of support plates 7 to rotate and fit together. At this time, the two sets of support plates 7 drive multiple sets of nozzles 8 to gather together for concentrated spraying. When it is necessary to replace the nozzles 8, the rotating sleeve 20 rotates to drive the limiting sleeve 21 to rotate, and the limiting sleeve 21 drives multiple sets of clearance grooves 25. Move to the top of the multiple sets of abutment blocks 23. At this time, the multiple sets of abutment blocks release their contact with the limiting sleeve 21. Then, push the fastening sleeve 19 to slide and release the contact with the sliding sleeve 17 and squeeze the multiple sets of push springs 32. At the same time, the sliding sleeve 17 drives the multiple sets of small racks 18 to mesh with the multiple sets of small gears 12. The multiple sets of small gears 12 drive the multiple sets of connecting rods and screws 11 to rotate. This causes the multiple sets of screws 11 to engage with the multiple sets of screw sleeves 10 and pull the multiple sets of clamping plates 14 to slide outward along the movable groove 29. This causes the multiple sets of clamping plates 14 to disengage from the inclined groove 16. Then, the insertion tube 15 on the nozzle 8 can be pulled out of the quick-release sleeve 9 to complete the quick disassembly of the nozzle 8.

[0040] When the nozzle 8 needs to be installed, the insertion tube 15 is inserted into the quick-release sleeve 9, and the sealing end is engaged in the sealing groove at the bottom of the sealing gasket 30. The sealing gasket 30 is then compressed. Multiple sets of push springs 32 push the fastening sleeve 19 and the sliding sleeve 17 to move. The sliding sleeve 17 is driven by multiple sets of small racks 18 meshing with multiple sets of small gears 12, so that multiple sets of screws 11 are threaded along the screw sleeve 10, thereby pushing the clamping plate 14 to clamp in the inclined groove 16 and holding the insertion tube 15. Then, multiple sets of abutments 23 disengage from the relief groove 25. The rotating sleeve 20 drives the limiting sleeve 21 to rotate, so that multiple sets of abutments 23 abut against the outer wall of the limiting sleeve 21, pressing the sliding sleeve 17 and completing the fixing of the nozzle 8.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
