Description

Technical Field

[0001] This utility model relates to the field of landscape engineering technology, specifically a spraying device for landscape greening construction. Background Technology

[0002] In landscaping projects, it is necessary to regularly spray pesticides or foliar fertilizers on the surface of green plants. In traditional techniques, this work is mostly done manually using backpack sprayers, which is laborious and inefficient.

[0003] A search revealed that patent CN219660755U discloses a garden pesticide spraying device. This device utilizes a wheeled frame, allowing the spraying mechanism to spray pesticides to both sides while the frame is moving. Pushing the frame is much easier than carrying the pesticide tank or box on one's back, thus solving the problem of the physical exertion of manually carrying pesticide tanks for spraying. The spraying mechanism sprays pesticides to both sides while the frame is moving to kill pests on the trees. A pump delivers the pesticide from the storage tank to a three-way pipe, which then delivers it to the nozzles, where it is sprayed out to kill pests on the trees.

[0004] While the above solution is more labor-saving and has higher spraying efficiency than a backpack manual sprayer, the two nozzles can only spray the lower plants, resulting in a small coverage area. Furthermore, the fixed nozzle angle can easily lead to many spray dead zones, which needs improvement. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the utility model, a spraying device for landscaping construction includes a water storage tank 8, a frame 10, a water pump 9, and a reduction motor 23 fixedly installed on a trolley. Multiple swing arms 13 are rotatably mounted on the outer wall of the frame 10 from top to bottom. The reduction motor 23 drives each swing arm 13 to swing back and forth on the frame 10. Spray pipes 14 are fixedly connected to both ends of the front wall of each swing arm 13. A nozzle 15 is installed at the outlet end of each spray pipe 14. Water delivery pipes 11 are fixedly installed on both outer walls of the frame 10. The inlet end of each spray pipe 14 is connected to the corresponding water delivery pipe 11 via a flexible hose 16. Each water delivery pipe 11 is connected to the outlet end of the water pump 9, and the inlet end of the water pump 9 is connected to the water storage tank 8.

[0022] By adopting the above-mentioned scheme, during the movement of the trolley, the water pump 9 is started, which can pump the foliar fertilizer or pesticide in the water storage tank 8 into the water delivery pipe 11, and then deliver it into each spray pipe 14 through the hose 16, and spray it out from the nozzle 15. During this process, the reduction motor 23 is started, which can drive each swing arm 13 to reciprocate and rotate on the frame 10, thereby driving each nozzle 15 to swing back and forth within a certain range, thereby effectively improving the working range of each nozzle 15, reducing spray dead angles, and achieving good results.

[0023] Specific combination Figure 2 and Figure 3In one embodiment of this utility model, a slide rod 19 is provided on the inner side of the frame 10. A plurality of guide sleeves 18 are slidably sleeved on the outer wall of the slide rod 19. The guide sleeves 18 are all fixedly connected to the inner wall of the frame 10. The bottom end of the slide rod 19 is connected to the output shaft of the reduction motor 23. A transmission pin 20 is fixedly connected to the corresponding position of each swing rod 13 on the outer wall of the slide rod 19. A transmission groove 22 is provided through the corresponding position of each transmission pin 20 on the outer wall of the swing rod 13. After the transmission pin 20 passes through the corresponding transmission groove 22, it is fixedly connected to a limit sleeve 21.

[0024] Furthermore, the output shaft of the geared motor 23 is fixedly sleeved with a turntable 24, and a connecting rod 25 is rotatably connected to the edge of the end face of the turntable 24. The end of the connecting rod 25 away from the turntable 24 is rotatably connected to the bottom end of the slide rod 19.

[0025] When the geared motor 23 is started, it can drive the turntable 24 to rotate. Then, the connecting rod 25 drives the slide rod 19 to move up and down reciprocally in the sliding sleeve 18. In turn, the transmission pin 20 and the transmission groove 22 work together to drive the swing rod 13 to rotate back and forth at a certain angle on the frame 10.

[0026] Specific combination Figure 2 and Figure 3 In one embodiment of the present invention, a short shaft 12 is rotatably inserted through the middle of the front wall of the swing rod 13. The short shaft 12 is fixedly connected to the frame 10. An arc-shaped groove 26 is provided on both sides of the front wall of the frame 10 at each short shaft 12. A guide pin 27 is fixedly inserted through the front wall of the swing rod 13 near both ends. The guide pin 27 is located in the corresponding arc-shaped groove 26.

[0027] By setting the short shaft 12, a rotational connection between the swing arm 13 and the frame 13 is achieved. By setting the guide pin 27 and the arc groove 26, the swing arm 13 can be guided on the frame 13, thereby improving the stability of the swing arm 13.

[0028] Specifically, in one embodiment of this utility model, each of the spray pipes 14 is equipped with a valve 17. By adjusting the opening and closing of the valve 17, the connection between the nozzle 15 and the water supply pipe 11 can be controlled, thereby facilitating the selection of a suitable nozzle 15 for spraying according to the height and growth status of the trees and plants. At the same time, only the valve 17 on the same side can be opened to spray on one side during the movement of the trolley.

[0029] Specific combination Figure 1In one embodiment of the present invention, the trolley includes a platform 1, with wheels 3 mounted on both sides of the platform 1, a trailer 2 fixedly mounted on one end of the platform 1, threaded tubes 4 fixedly mounted on both sides of the platform 1, a screw 5 passing through the threaded tube 4, a handwheel 6 fixedly mounted on the top end of the screw 5, and a support plate 7 rotatably connected to the bottom end of the screw 5 through a bearing seat.

[0030] By using the aforementioned trolley, the trolley can be towed by a tractor or other traction equipment, and the traction equipment can be used to power the water pump 9 and the geared motor 23. When the spraying device is not in use, before disconnecting the trailer 2 from the traction equipment, the screw 5 can be turned by the handwheel 6 to make the support plate 7 contact the ground, thereby ensuring the stability of the trolley when parked.

[0031] In addition, in other preferred embodiments of this utility model, the trolley may also be a vehicle with its own power source or a handcart, etc.
