[0029] Example:

[0030] See also Figure 1 - Figure 4A forestry spray device comprises a pesticide box 1, a liquid inlet 2 is arranged on the top of the pesticide box 1, a liquid outlet pipe 3 is connected to one side of the pesticide box 1 near the bottom edge, a connecting pipe 4 is fixedly connected to the side of the liquid outlet pipe 3 away from the pesticide box 1, a sprayer 5 is fixedly connected to the end of the connecting pipe 4 away from the liquid outlet pipe 3, a protective cover 6 is rotatably arranged on the outside of the connecting pipe 4, four mounting tubes 7 are installed through one side of the protective cover 6, a fan 8 is fixedly connected to the inside of the mounting tube 7, and a plurality of sponge strips 9 are fixedly connected to the inside of the mounting tube 7.

[0031] Specifically, the air outlet end of the fan 8 faces the sprayer 5 , and a plurality of sponge strips 9 are arranged on one side of the air inlet end of the fan 8 .

[0032] In this solution, a pump body is provided inside the pesticide box 1, one end of the connecting pipe 4 passes through the liquid outlet pipe 3 and is provided inside the pesticide box 1, the connecting pipe 4 is connected to the liquid outlet end of the pump body, the pump body can suck the pesticide inside the pesticide box 1 into the connecting pipe 4, the sprayer 5 can spray the pesticide outward in a mist form, the protective cover 6 can block a part of the pesticide mist that drifts toward the staff with the wind, the fan 8 can blow air to the spray end of the sprayer 5 by wind force, which can not only increase the spraying range of the pesticide, but also effectively prevent the pesticide mist from drifting toward the staff by wind force, and the air inlet end of the fan 8 faces the staff, which can generate suction on the air in front of the staff, thereby absorbing the pesticide mist in the air in this area, further improving the protective effect of the device on the staff, and the sponge strip 9 can absorb the pesticide mist absorbed by the fan 8.

[0033] See also Figure 1 - Figure 3 The outside of the connecting pipe 4 is fixedly sleeved with a fixed cylinder 10, and the outside of the fixed cylinder 10 is fixedly connected to two plastic support strips 11, and one end of the two plastic support strips 11 away from the fixed cylinder 10 is fixedly connected to one side of the protective cover 6.

[0034] Specifically, the protective cover 6 is rotatably disposed outside the fixed tube 10 , and a threaded adjustment rod 12 is fixedly connected to the outside of the protective cover 6 , and a threaded end of the threaded adjustment rod 12 is threadedly connected to the outside of the fixed tube 10 .

[0035] In this solution, the plastic support strip 11 can be deformed to a certain extent and provide support for the protective cover 6. When the angle of the protective cover 6 changes, the plastic support strip 11 can be deformed and still provide support for the protective cover 6. The threaded adjustment rod 12 is used to adjust the angle of the protective cover 6 on the connecting pipe 4. When the spraying angle of the connecting pipe 4 needs to be changed, the staff can change the angle of the protective cover 6 by rotating the threaded adjustment rod 12 to ensure that the protective cover 6 can block the pesticide mist to the greatest extent.

[0036] See also Figure 1 and Figure 4 The inside of the liquid outlet pipe 3 is rotatably connected with an inner connecting pipe 13 , and one end of the inner connecting pipe 13 away from the liquid outlet pipe 3 is connected to one side of the pesticide box 1 .

[0037] Specifically, a plurality of circular holes 14 are formed through the outside of the inner connecting tube 13 , and a limiting hole 15 is formed through the outside of the liquid outlet tube 3 . The diameter of the limiting hole 15 matches the diameter of the plurality of circular holes 14 .

[0038] Specifically, a spring 16 is fixedly connected to the outside of the limiting hole 15 , a limiting block 17 is slidably connected to the inside of the limiting hole 15 , and one end of the spring 16 away from the limiting hole 15 is fixedly connected to the outside of the limiting block 17 .

[0039] In this solution, a sealing strip is installed at the connection between the liquid outlet pipe 3 and the inner connecting pipe 13, and a plurality of circular holes 14 are evenly distributed on the inner connecting pipe 13. The length of the limit block 17 exceeds the total length of the limit hole 15 and one circular hole 14. The staff can pull the limit block 17 upward. At this time, the spring 16 is stretched to generate elastic force. After the limit block 17 moves up, it disengages from the circular hole 14 and the limit hole 15. Then the staff can rotate the liquid outlet pipe 3 to match its limit hole 15 with different circular holes 14. After matching to a suitable circular hole 14, the staff can loosen the limit block 17. Under the action of the elastic force of the spring 16, the limit block 17 is reinserted into the limit hole 15 and the circular hole 14, so that the position of the liquid outlet pipe 3 remains fixed, thereby keeping the angle of the connecting pipe 4 fixed, which can not only ensure the spraying range of the connecting pipe 4, but also play a supporting role for the connecting pipe 4 and its components, thereby reducing the workload of the staff.

[0040] Working principle: Before spraying, the staff pours the pesticide liquid into the pesticide box 1 from the liquid inlet 2. Then, according to the spraying height of the saplings, the staff pulls the limit block 17 upwards by hand and rotates the liquid outlet pipe 3 to match the limit hole 15 with the circular hole 14 at the appropriate position. After the matching is completed, the staff releases the limit block 17, and the spring 16 resets the limit block 17 to complete the fixing of the angle of the connecting pipe 4;

[0041] Next, the staff turns on the pump body in the pesticide box 1 to transfer the pesticide to the connecting pipe 4, and sprays the pesticide in a mist form toward the seedlings through the sprayer 5. At the same time, the staff turns on the fan 8, and the fan 8 blows the pesticide mist toward the seedlings and even farther, thereby effectively preventing the pesticide from drifting toward the staff and playing a protective role for the staff. Moreover, the air inlet end of the fan 8 inhales the air in front of the staff, thereby further absorbing the pesticide mist in front of the staff, thereby improving the protective effect of the device on the staff, and then the pesticide inhaled by the fan 8 is absorbed by the sponge strip 9.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
