[0022] In order to achieve the above technical purpose, another technical solution adopted by the present invention is:

[0023] A spraying method of a fog machine with adjustable spray width, including spray mode one and spray mode two;

[0024] Wherein, spray mode 1 includes the following steps:

[0025] (A1) Start the inner hydraulic cylinder and the outer hydraulic cylinder, the inner hydraulic cylinder drives the inner blade to rotate so that the inner blade opens, and the outer hydraulic cylinder drives the outer blade to rotate so that the outer blade opens, and the inner blade and the outer blade open to a preset position and then stop opening;

[0026] (A2) Start the fan of the wind tube. The high-speed airflow generated by the rotation of the fan of the wind tube moves along the outer surface of the inner tube of the wind tube after passing through the spoiler blades;

[0027] (A3) An external gas source and an external oil source supply gas and oil to the combustion chamber through pipelines. A spark plug is provided on the combustion chamber. When the spark plug is activated, combustion begins in the combustion chamber. The hot air flow generated by the combustion in the combustion chamber is ejected out at high speed through the tail pipe. The external medicine box inputs liquid medicine into the tail pipe through the medicine inlet pipe. Under the high temperature and high-speed air flow disturbance of the hot air flow, the liquid medicine in the tail pipe is cracked, broken, and evaporated into fine droplets, which are ejected from the tail pipe outlet. The fine droplets move with the high-speed air flow generated by the rotation of the wind tube fan; after passing through the inner tube of the wind tube, the air flow loses the restraining effect of the inner and outer blades, and due to inertia, it spreads to the surroundings at a certain angle along the outer cylindrical surface of the inner tube of the wind tube, thereby driving the liquid medicine ejected from the tail pipe to spray to the surroundings, forming a smoke-like liquid medicine with a wide coverage area, a short ejection distance, and weak penetration;

[0028] Wherein, spray mode 2 includes the following steps:

[0029] (B1) Start the inner hydraulic cylinder and the outer hydraulic cylinder, the inner hydraulic cylinder drives the inner blade to rotate so that the inner blade is closed, and the outer hydraulic cylinder drives the outer blade to rotate so that the outer blade is closed, and the inner blade and the outer blade are closed to a preset position and then stop closing;

[0030] (B2) Start the air duct fan, and the high-speed airflow generated by the rotation of the air duct fan moves along the outer surface of the inner tube of the air duct after passing through the spoiler blades;

[0031] (B3) An external gas source and an external oil source supply gas and oil to the combustion chamber through pipelines. A spark plug is provided on the combustion chamber. When the spark plug is activated, combustion begins in the combustion chamber. The hot air flow generated by the combustion in the combustion chamber is ejected out at high speed through the tail pipe. The external medicine box inputs liquid medicine into the tail pipe through the medicine inlet pipe. Under the high temperature and high-speed air flow disturbance of the hot air flow, the liquid medicine in the tail pipe is cracked, broken, and evaporated into fine droplets, which are ejected from the tail pipe outlet. The fine droplets move with the high-speed air flow generated by the rotation of the wind tube fan; the air flow is constrained by the inner and outer blades, and due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube of the wind tube, driving the liquid medicine ejected from the tail pipe to gather toward the center, forming a smoke-like liquid medicine with a longer ejection distance, faster speed, and stronger penetration.

[0032] The beneficial effects of the present invention are as follows: the spray range-adjustable fogger and the spray method of the present invention can adjust the spray range and angle according to different types of trees, expand the application range of the pulse fogger, and reduce pesticide waste and environmental pollution.

[0033] The tail pipe of the present invention is connected with the medicine inlet pipe through a nozzle, and the medicine inlet pipe sprays the medicine liquid into the tail pipe through the nozzle to realize primary crushing. When the tail pipe sprays the medicine liquid after secondary crushing, the motor of the air duct fan drives the blades to rotate to generate a high-speed airflow, which moves along the gap around the inner tube of the air duct after passing through the spoiler blades. Due to the gathering and dispersion drainage structure of the inner tube of the air duct, when the inner hydraulic cylinder and the outer hydraulic cylinder are both contracted, driving the inner blades and the outer blades to open, the airflow loses the restraining effect of the inner blades and the outer blades when passing through the inner tube of the air duct, and diffuses to the surroundings at a certain angle along the outer wall of the inner tube of the air duct due to inertia, driving the medicine liquid sprayed from the tail pipe to spray to the surroundings, forming a smoke screen with a wider coverage area but a shorter spray distance and weaker penetration. This mode is suitable for forest types with smaller vegetation depth and lower density, such as street trees, and has the characteristics of saving pesticides, not easy to waste, less pollution and fast application speed. When the inner hydraulic cylinder and the outer hydraulic cylinder are extended to drive the inner blades and the outer blades to close, the airflow is still constrained by the inner blades and the outer blades when passing through the inner tube of the wind tube. Due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube of the wind tube, driving the liquid medicine sprayed from the tail pipe to gather toward the center, forming a smoke with a long spray distance, a fast speed and strong penetration. The smoke with strong penetration can penetrate deeply into the jungle more easily and improve the effect of pesticide application. This mode is suitable for forest types with large vegetation depth and high density, such as large artificial forests, natural forests, etc., and has the characteristics of strong penetration and wide range of action. In addition, in the face of trees of different heights, the connecting rod connected to the external angle adjustment device can also be adjusted to change the elevation angle of the wind tube spray. The present invention can adjust the opening and closing of the guide blades and the spray angle according to different types of trees, and spray liquid medicines of different forms and characteristics according to local conditions, so as to expand the scope of application of the pulse fogger, reduce pesticide waste and reduce environmental pollution.

[0060] like Figure 4 , 11 As shown, the spray body includes an outer shell 12, a combustion chamber 13, a tail pipe 14, a spoiler blade 22 and an inner tube 11 of the wind cylinder. The outer shell 12 is connected to the inner wall of the wind cylinder body 3 through the spoiler blade 22. The combustion chamber 13 is located on the inner side of the outer shell 12. The combustion chamber 13 is connected to the tail pipe 14. The tail pipe 14 is connected to the medicine inlet pipe.

The inner tube 11 of the wind cylinder is connected to the spoiler blade 22, and the inner tube 11 of the wind cylinder is located on the inner side of multiple guide blades.

[0062] like Fig.13As shown, the combustion chamber 13 is connected to a pipe 21, and the pipe 21 passes through the outer shell 12 and the air cylinder body 3 and is connected to an external gas source and an external oil source; the combustion chamber 13 is connected to a plurality of tail pipes 14, and the plurality of tail pipes 14 are evenly spaced along the circumferential direction, and the plurality of tail pipes 14 pass through the front end of the outer shell 12 and extend to the outside of the outer shell 12, and each tail pipe 14 is connected to a medicine inlet pipe, and the medicine inlet pipe passes through the outer shell 12 and the air cylinder body 3 and is connected to an external medicine box, and there is a spoiler blade 22 between every two tail pipes 14.

Figure 6-11 When the airflow is opened as shown (the inner blades 8 and the outer blades 7 are opened to the maximum extent and then stop opening), the airflow loses the restraining effect of the inner blades 8 and the outer blades 7 after passing through the A of the inner tube 11 of the air duct, and due to inertia, it spreads to the surroundings at a certain angle along the outer wall of the inner tube 11 of the air duct, driving the liquid sprayed from the tail pipe 14 to spray to the surroundings, as shown in FIG.

When the inner hydraulic cylinder 601 and the outer hydraulic cylinder 501 are extended to drive the inner blade 8 and the outer blade 7 as shown in the figure, the inner hydraulic cylinder 601 and the outer hydraulic cylinder 501 are extended to drive the inner blade 8 and the outer blade 7 as shown in the figure. Figure 1-4When the airflow is closed (when adjacent outer blades 7 are in contact, the outer blades 7 stop closing; when adjacent inner blades 8 are in contact, the inner blades 8 stop closing), the airflow is still constrained by the inner blades 8 and the outer blades 7 at B of the inner tube 11 of the air duct, and due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube 11 of the air duct, driving the liquid sprayed from the tail pipe 14 to gather toward the center, as shown in FIG. Figure 5 As shown, smoke with a long spray distance, fast speed and strong penetration is formed, and smoke with strong penetration can penetrate deeper into the jungle more easily, thereby improving the effect of pesticide application; this mode is suitable for forest types with large vegetation depth and high density, such as large artificial forests, natural forests, etc., and has the characteristics of strong penetration and wide range of action. In addition, facing trees of different heights, the connecting rod 9 connected to the external angle adjustment device can also be adjusted to change the elevation angle of the wind tube spray. The present invention can adjust the opening and closing of the guide blades and the spray angle according to different types of trees, and spray liquids of different forms and characteristics according to local conditions, so as to expand the scope of application of the pulse fogger, reduce pesticide waste and alleviate environmental pollution.

[0065] This embodiment also provides a spraying method of a fog machine with adjustable spray width, including spray mode 1 and spray mode 2;

[0066] Wherein, spray mode 1 includes the following steps:

[0067] (A1) Start the inner hydraulic cylinder 601 and the outer hydraulic cylinder 501. The inner hydraulic cylinder 601 drives the inner blade 8 to rotate so that the inner blade 8 opens. The outer hydraulic cylinder 501 drives the outer blade 7 to rotate so that the outer blade 7 opens. The inner blade 8 and the outer blade 7 open to a preset position and then stop opening.

[0068] (A2) Start the wind tube fan, and the high-speed airflow generated by the rotation of the wind tube fan passes through the spoiler blades 22 and moves along the outer surface of the wind tube inner tube 11;

[0069] (A3) An external gas source and an external oil source supply gas and oil to the combustion chamber 13 through a pipeline 21. A spark plug is provided on the combustion chamber 13. When the spark plug is activated, combustion begins in the combustion chamber 13. The hot air flow generated by the combustion in the combustion chamber 13 is ejected out at high speed through the tail pipe 14. The external medicine box inputs liquid medicine into the tail pipe 14 through the medicine inlet pipe. Under the high temperature and high speed air flow disturbance of the hot air flow, the liquid medicine in the tail pipe 14 is cracked, crushed, and evaporated into fine droplets, which are ejected from the outlet of the tail pipe 14. The fine droplets move with the high-speed air flow generated by the rotation of the wind tube fan. After passing through the inner tube 11 of the wind tube, the air flow loses the restraining effect of the inner blades 8 and the outer blades 7, and due to inertia, it spreads to the surroundings at a certain angle along the outer cylindrical surface of the inner tube 11 of the wind tube, thereby driving the liquid medicine ejected from the tail pipe 14 to spray to the surroundings, such as Fig.12As shown, a smoke-like liquid medicine is formed with a wider coverage area, a shorter spraying distance and weaker penetration. This mode is suitable for forest types with smaller vegetation depth and lower density, such as street trees, and has the characteristics of saving pesticides, not easy to waste, less pollution and fast application speed.

[0070] Wherein, spray mode 2 includes the following steps:

[0071] (B1) Start the inner hydraulic cylinder 601 and the outer hydraulic cylinder 501. The inner hydraulic cylinder 601 drives the inner blade 8 to rotate so that the inner blade 8 is closed. The outer hydraulic cylinder 501 drives the outer blade 7 to rotate so that the outer blade 7 is closed. The inner blade 8 and the outer blade 7 are closed to a preset position and then stop closing.

[0072] (B2) The wind tube fan is started, and the high-speed airflow generated by the rotation of the wind tube fan passes through the spoiler blades 22 and moves along the outer surface of the wind tube inner tube 11;

[0073] (B3) An external gas source and an external oil source supply gas and oil to the combustion chamber 13 through a pipeline 21. A spark plug is provided on the combustion chamber 13. When the spark plug is started, combustion begins in the combustion chamber 13. The hot air flow generated by the combustion in the combustion chamber 13 is ejected out at high speed through the tail pipe 14. The external medicine box inputs liquid medicine into the tail pipe 14 through the medicine inlet pipe. Under the high temperature and high speed air flow disturbance of the hot air flow, the liquid medicine in the tail pipe 14 is cracked, broken, and evaporated into fine droplets, which are ejected from the outlet of the tail pipe 14. The fine droplets move with the high-speed air flow generated by the rotation of the wind tube fan; the air flow is constrained by the inner blades 8 and the outer blades 7, and due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube 11 of the wind tube, driving the liquid medicine ejected from the tail pipe 14 to gather toward the center, such as Figure 5 As shown, a mist-like liquid medicine is formed with a longer spray distance, faster speed and stronger penetration. The smoke with stronger penetration can penetrate deeper into the jungle more easily, improving the effect of pesticide application. This mode is suitable for forest types with a large vegetation depth and high density, such as large artificial forests and natural forests, and has the characteristics of strong penetration and wide range of action.
