[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3 As shown, a water-saving spraying device for agricultural irrigation includes: an equipment platform 1, a push handle 11 is provided on the equipment platform 1, and storage chambers 12 are provided on both side walls of the equipment platform 1; a spraying mechanism 2, the spraying mechanism 2 includes an adjustable atomizing nozzle 21; a blower mechanism 3, the blower mechanism 3 is arranged below the equipment platform 1, and the blower mechanism 3 is arranged behind the atomizing nozzle 21; an expansion plate 4, the expansion plate 4 is fixedly slidably connected to the storage chamber 12; a travel mechanism 5, the travel mechanism 5 is arranged at the bottom of the expansion plate 4, and the travel mechanism 5 can be adjusted in height.

[0023] The spraying mechanism 2 also includes a water tank 22, a water pump 23, a main water pipe 24 and a branch pipe 25. The water pump 23 is connected to the water tank 22, the main water pipe 24 is connected to the water outlet of the water pump 23, and the branch pipe 25 is arranged at the bottom of the main water pipe 24. Water or medicine is added to the water tank 22, and the water pump 23 pumps the water in the water tank 22 into the main water pipe 24. The main water pipe 24 transports the water to the branch pipe 25. Then, the water is sprayed out as water mist from the atomizing nozzle 21 under the pressure of the water pump 23. Compared with direct watering, the water mist saves water resources, and the same amount of water can be used to spray crops on a larger area.

[0024] The water tank 22 and the water pump 23 are arranged above the equipment platform 1, and the equipment platform 1 supports the water tank 22 and the water pump 23. The main water pipe 24 runs through the equipment platform 1, and the lower part of the main water pipe 24 is located below the equipment platform 1. The branch pipe 25 and the atomizing nozzle 21 are arranged below the equipment platform 1. When spraying irrigation, the equipment platform 1 can block water from being sprayed onto the equipment platform 1, so that the water mist can be used with maximum efficiency.

[0025] The branch pipe 25 is in a "soil" shape. Since the bottom leaves of crops mainly composed of strawberries are numerous and cover a wide area, while the top occupies a small area, the lower branch pipe is longer and can spray a larger area, and the upper branch pipe has a smaller spraying area. The rear end of the atomizing nozzle 21 is in an "L" shape. The rear end of the atomizing nozzle 21 is connected to the port of the branch pipe 25, and the front end of the atomizing nozzle 21 is aligned with the crops. The inner wall of the port of the branch pipe 25 is provided with internal threads, and the outer wall of the rear end of the atomizing nozzle 21 is provided with external threads. The rear end of the atomizing nozzle 21 is screwed onto the port of the branch pipe 25. By screwing, the atomizing nozzle 21 can rotate relative to the branch pipe 25 to change the orientation of the atomizing nozzle 21. When spraying, the spraying position can be changed according to the specific height of the crops, so that the sprayed water or liquid medicine can be efficiently utilized.

[0026] As Figure 2 shown, the blowing mechanism 3 includes a connecting rod 31 and a hair dryer 32. The connecting rod 31 is fixedly connected to the bottom of the equipment platform 1, and the hair dryer 32 is rotatably connected to the bottom of the connecting rod 31. The connecting rod 31 and the hair dryer 32 are located behind the atomizing nozzle 21 to prevent the atomizing nozzle 21 from spraying water on the hair dryer 32, causing waste.

[0027] A connecting shaft 33 passes through the bottom of the connecting rod 31 and the top of the hair dryer 32. Both ends of the connecting shaft 33 are fixedly connected with fastening nuts 34. The hair dryer 32 can rotate around the connecting shaft 33 to adjust the blowing angle. When the blowing angle needs to be adjusted, loosen the fastening nuts 34 to make the hair dryer 32 rotatable. After adjusting the blowing angle, tighten the fastening nuts 34 to fix the rotation angle of the hair dryer 32. The rotation angle of the hair dryer 32 is based on the standard that after starting, the back of the leaves of the crops (such as strawberries) can be blown out. When the back of the leaves is shown, the water or liquid medicine sprayed by the atomizing nozzle 21 can adhere to the back of the leaves, which can moisten the back of the leaves or control pests and diseases, eliminating the need for manual leaf turning operation. As the device moves forward along the crop planting direction, the backs of all crops can be sprayed with water or liquid medicine.

[0028] To adapt to different row spacings of different crop plantings, an extension board 4 is used to adjust the overall width of the equipment, so that the guide wheels 54 can move on the land without crops. The extension board 4 is a rectangular board, and the extension board 4 is provided with a number of connection holes 41. The connection holes 41 are evenly distributed along the short side direction of the extension board 4. A connection piece 13 is fixedly connected to the side wall of the equipment platform 1. The connection piece 13 serves as an extension of the side of the equipment platform 1. One end of the connection piece 13 is located above the connection hole 41, and two pins 42 are detachably connected to the connection piece 13. When the telescopic length of the extension board 4 is determined, insert the pins 42 into the corresponding connection holes 41. The pins 42 limit the movement of the extension board 4 to complete the determination of the overall width of the device.

[0029] The travel mechanism 5 includes a positioning leg 51, a threaded sleeve 52, a threaded rod 53 and a guide wheel 54. The positioning leg 51 is fixedly connected to the bottom of the expansion plate 4. The positioning leg 51 moves and changes in width together with the expansion plate 4. The threaded sleeve 52 is fixedly connected to the bottom of the positioning leg 51. The threaded rod 53 is threadedly connected to the threaded sleeve 52. The guide wheel 54 is rotatably connected to the bottom of the threaded rod 53. By rotating the threaded rod 53, the vertical spacing between the guide wheel 54 and the threaded sleeve 52 is changed, and the height adjustment of the equipment platform 1 is further realized. The height of crops that need to be sprayed at different heights or crops cultivated on elevated platforms can be adaptively adjusted to ensure that crops at different heights can be sprayed and the crops will not hinder the movement of the device.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
