When the guide blades are opened outward, they can be embedded in the blade grooves.

[0019] In order to achieve the above technical purpose, another technical solution adopted by the present invention is:

[0020] A spraying method of a smoke and water mist spraying machine with adjustable spray width, comprising a water mist mode step and a smoke mode step;

[0021] Among them, the water mist mode steps include:

[0022] (A1) Start the steering gear, which drives the guide vanes to rotate and open the guide vanes. After the multiple guide vanes are opened to a preset position, they stop opening. Start the outer sleeve telescopic adjustment structure, which drives the outer sleeve of the air guide tube to move backward, and stops moving after it moves to a preset position. At this time, part of the structure of the air tube body is located inside the outer sleeve of the air guide tube and the guide vanes, and the front end of the inner tube of the air tube extends to the outside of the outer sleeve of the air guide tube and the guide vanes. The external medicine box provides liquid medicine to multiple nozzles through a circular medicine inlet pipe.

[0023] (A2) Start the air duct fan. 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. Because the airflow loses the restraining effect of the guide blades after passing through the inner tube of the air duct, it spreads to the surroundings at a certain angle along the outer surface of the inner tube of the air duct due to inertia, thereby driving the liquid sprayed from the nozzle to spray in all directions, forming a water mist liquid with a wide coverage area, a short spray distance and weak penetration.

[0024] Among them, the smoke mode steps include:

[0025] (B1) Start the telescopic adjustment structure of the outer sleeve, which drives the outer sleeve of the air guide tube to move forward away from the main body of the air guide tube, and stops moving after moving to a preset position. At this time, the front end of the inner tube of the air guide tube is located on the inner side of the outer sleeve of the air guide tube; start the steering gear, which drives the guide vane to rotate and close the guide vane. The multiple guide vanes are closed together to the preset position and then stop closing;

[0026] (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;

[0027] (B3) An external air source and an external oil source supply air and oil to the combustion chamber. 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 medicine liquid 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 medicine liquid in the tail pipe is cracked, broken, and evaporated into fine droplets to form a high-temperature smoke-like medicine liquid, which is discharged from the tail pipe outlet. The high-temperature smoke-like medicine liquid moves with the high-speed air flow generated by the rotation of the air duct fan; the air flow is constrained by the guide vane, and due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube of the air duct, driving the smoke-like medicine liquid ejected from the tail pipe to gather toward the center, forming a smoke-like medicine liquid with a longer ejection distance, faster speed, and stronger penetration.

[0028] The beneficial effects of the present invention are as follows: the integrated smoke sprayer and method with adjustable spray width of the present invention can adjust the spray range and angle according to different types of trees, spray out two different forms of liquid medicine, smoke and water mist, thereby expanding the application scope of the pulse fogger and reducing pesticide waste and environmental pollution.

[0029] When working, the motor of the wind tube fan drives the blades to rotate, and the high-speed airflow generated moves along the gap around the inner tube of the wind tube after passing through the spoiler blades. When the hydraulic oil in the hydraulic cylinder flows back, the hydraulic rod in the hydraulic cylinder is affected by the external load and contracts inward, driving the outer sleeve of the wind guide tube to move backward. The steering gear is controlled to rotate through the opening and closing control program of the guide blade of the external controller, driving the guide blade to open. Due to the special gathering and dispersion air guide structure of the inner tube of the wind tube, the airflow loses the restraining effect of the guide blade after passing through the inner tube of the wind tube, and diffuses to the surroundings at a certain angle along the outer wall of the inner tube of the wind tube due to inertia, driving the liquid sprayed from the nozzle to spray around, forming a water curtain with a wide coverage area, but a short spray distance and weak penetration; this mode is suitable for forest types with small vegetation depth and low density, such as street trees, etc., and has the characteristics of saving pesticides, not easy to waste, less pollution, and fast application speed. When the hydraulic oil in the hydraulic cylinder is pumped in, the hydraulic rod is extended by the hydraulic pressure, driving the outer sleeve of the air guide tube to move forward, and the guide vane opening and closing control program of the external controller controls the steering gear to rotate, thereby driving the guide vane to rotate around the bottom axis to make it closed as a whole. The airflow in the inner tube of the air tube is still constrained by the guide vane. Due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube of the air tube, driving the secondary broken smoke-like liquid medicine sprayed from the tail pipe to gather toward the center, forming a smoke with a long spray distance, fast speed and strong penetration. This smoke with strong penetration can more easily penetrate into the jungle 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 air 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 two different forms of liquid medicine, smoke and water mist, according to local conditions, to achieve the functions of expanding the application range of the pulse fogger, reducing pesticide waste and alleviating environmental pollution.

[0058] In this embodiment, in the spray body, Fig.15 As shown, the outer shell 6 is fixedly connected to the inner wall of the air duct body 2 through a plurality of spoiler blades 11, and the plurality of spoiler blades 11 are evenly spaced along the inner wall of the air duct body 2 and the outer wall of the outer shell 6.

Specifically, there are eight tail pipes 8 and they are evenly distributed on the circumference of the end of the combustion chamber 7. There is a certain gap between the tail pipe 8 and the inner tube 9 of the air cylinder.

[0060] In this embodiment, the outer sleeve telescopic adjustment structure includes a plurality of hydraulic cylinders 4, one end of the hydraulic cylinder 4 is connected to the outer wall of the wind cylinder body 2 1, and the other end of the hydraulic cylinder 4 is connected to the outer wall of the air guide sleeve outer sleeve 3 through a connecting plate 19. The air guide sleeve outer sleeve 3 is sleeved on the outside of the wind cylinder body 1 2, and the inner diameter of the air guide sleeve outer sleeve 3 is larger than the outer diameter of the wind cylinder body 1 2. The hydraulic cylinder 4 is used to drive the air guide sleeve outer sleeve 3 to telescopically move forward and backward along the outside of the wind cylinder body 1 2. The hydraulic cylinder 4 is connected to an external hydraulic oil tank through a hydraulic pump.

[0061] In this embodiment, Fig.17 and Fig.18 As shown, the inner tube 9 of the air duct includes a cylindrical section 9A, a truncated cone transition section (including a truncated cone transition section 1 9B and a truncated cone transition section 2 9C) and a truncated cone section 9D. The front end outer diameter of the truncated cone transition section 1 9B is greater than the rear end outer diameter, the front end outer diameter of the truncated cone transition section 2 9C is greater than the rear end outer diameter, the front end outer diameter of the truncated cone section 9D is smaller than the rear end outer diameter, the bevel angle of the outer circular surface of the truncated cone transition section 1 9B is smaller than the bevel angle of the outer circular surface of the truncated cone transition section 2 9C, ​​the cylindrical section 9A is located between multiple tail pipes 8, and the outer circular surfaces of the truncated cone transition section 1 9B and the truncated cone transition section 2 9C are fixedly connected to the front end of the spoiler blade 11.

[0063] When the integrated machine of this embodiment is working, the motor 13 of the air duct fan drives the blades 14 to rotate, and the high-speed airflow generated moves along the gap around the air duct inner tube 9 after passing through the spoiler blades 11. When the hydraulic oil in the hydraulic cylinder 4 flows back, the hydraulic rod in the hydraulic cylinder 4 contracts inwards under the action of the external load, driving the outer sleeve 3 of the air duct to move backward, and the steering gear 20 is controlled to rotate through the guide blade opening and closing control program of the external controller, driving the guide blade 10 to open, such as Figure 7-Figure 13 As shown, the guide blade 10 is in the open state. Due to the special gathering and dispersing air guiding structure of the inner tube 9 of the wind tube, the air flow passes through the A of the inner tube 9 of the wind tube (such as Figure 8 ) after losing the restraining effect of the guide blade 10, due to inertia, it spreads to the surroundings at a certain angle along the outer wall of the inner tube 9 at A, driving the liquid sprayed from the nozzle 5 to spray around. Fig.14As shown, a water curtain with a wide coverage area is formed, but the spraying distance is short and the penetration is weak; this mode is suitable for forest types with small vegetation depth and low density, such as roadside trees, etc., and has the characteristics of saving pesticides, not easy to waste, less pollution, and fast application speed. When the hydraulic oil in the hydraulic cylinder 4 is pumped in, the hydraulic rod is pushed and extended by the hydraulic pressure, driving the outer sleeve 3 of the air guide tube to move forward, and the guide vane opening and closing control program of the external controller controls the steering gear 20 to rotate, thereby driving the guide vane 10 to rotate around the bottom axis to make it closed as a whole, as shown in FIG. Figure 1-Figure 5 As shown, the guide vane 10 is in the closed state. The airflow is at B of the inner tube 9 of the wind tube (such as Figure 2 ) is still constrained by the guide vane 10, and due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube 9 of the wind tube, driving the secondary broken smoke-like liquid medicine sprayed from the tail pipe 8 to gather toward the center. Figure 6 As shown (where velocity magnitude indicates the magnitude of velocity), smoke with a longer spray distance, faster speed and stronger penetration is formed. This smoke with stronger penetration can more easily penetrate into the jungle and improve the effect of pesticide application. This mode is suitable for forest types with a large vegetation depth and a high density, such as large artificial forests, natural forests, etc., and has the characteristics of strong penetration and a wide range of action. In addition, in the face of trees of different heights, the connecting rod 15 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 blade 10 and the spray angle according to different types of trees, and can be adapted to local conditions to spray two different forms of liquid medicine, smoke and water mist, to achieve the functions of expanding the scope of application of the pulse fogger, reducing pesticide waste and alleviating environmental pollution.

[0065] Among them, the water mist mode steps include:

[0066] (A1) Start the steering engine 20, which drives the guide vanes 10 to rotate and open the guide vanes 10. After the guide vanes 10 open to a preset position, they stop opening. Start the outer sleeve telescopic adjustment structure, which drives the outer sleeve 3 of the air guide tube to move backward, and stops moving after moving to a preset position. At this time, part of the structure in the air tube body 2 is located on the inner side of the outer sleeve 3 of the air guide tube and the guide vanes 10 (such as Fig.13 ), the front end of the inner tube 9 of the wind tube extends to the outside of the outer sleeve 3 of the wind guide tube and the guide vane 10; the external medicine box provides liquid medicine to multiple nozzles 5 through a circular medicine inlet pipe;

[0067] (A2) Start the air duct fan, and the high-speed airflow generated by the rotation of the air duct fan moves along the outer circumferential surface of the truncated cone transition section 1 9B and the outer circumferential surface of the truncated cone transition section 2 9C in the air duct inner tube 9 after passing through the spoiler blades 11; Figure 7 As shown, after the airflow passes through the A of the inner tube 9 of the wind tube, it loses the restraining effect of the guide vane 10, and due to inertia, it spreads to the surroundings at a certain angle along the outer circumference of the truncated cone transition section 1 9B and the outer circumference of the truncated cone transition section 2 9C in the inner tube 9 of the wind tube, thereby driving the liquid sprayed from the nozzle 5 to spray to the surroundings, forming a water mist liquid with a wide coverage area, a short spray distance and weak penetration;

[0068] Among them, the smoke mode steps include:

[0069] (B1) Start the telescopic adjustment structure of the outer sleeve, which drives the outer sleeve 3 of the air guide tube to move forward away from the front of the air guide tube body 2, and stops moving after moving to the preset position.

[0070] (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;

[0071] (B3) An external gas source and an external oil source supply gas and oil to the combustion chamber 7. A spark plug is provided on the combustion chamber 7. When the spark plug is activated, combustion begins in the combustion chamber 7. The hot air flow generated by the combustion in the combustion chamber 7 is ejected out at high speed through the tail pipe 8. The external medicine box inputs liquid medicine into the tail pipe 8 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 8 is cracked, crushed, and evaporated into fine droplets to form a high temperature smoke-like liquid medicine, which is discharged from the outlet of the tail pipe 8. The high temperature smoke-like liquid medicine moves with the high speed air flow generated by the rotation of the air duct fan; Figure 2 As shown, the airflow is constrained by the guide vanes 10, and due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube 9 of the wind tube, driving the smoke-like liquid medicine sprayed from the tail pipe 8 to gather toward the center, forming a smoke-like liquid medicine with a longer spray distance, faster speed and stronger penetration.

8. The spraying method of the integrated smoke and water mist sprayer with adjustable spray width as claimed in claim 1, characterized in that: It includes a water mist mode step and a smoke mode step; Among them, the water mist mode steps include: (A1) Start the steering gear, which drives the guide vanes to rotate and open the guide vanes. After the multiple guide vanes open to a preset position, they stop opening. Start the outer sleeve telescopic adjustment structure, which drives the outer sleeve of the air guide tube to move backward, and stops moving after moving to a preset position. At this time, part of the structure of the air tube body is located inside the outer sleeve of the air guide tube and the guide vanes, and the front end of the inner tube of the air tube extends to the outside of the outer sleeve of the air guide tube and the guide vanes. The external medicine box provides liquid medicine to multiple nozzles through a circular medicine inlet pipe. (A2) Start the air duct fan. 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. Because the airflow loses the restraining effect of the guide blades after passing through the inner tube of the air duct, it spreads to the surroundings at a certain angle along the outer surface of the inner tube of the air duct due to inertia, thereby driving the liquid sprayed from the nozzle to spray in all directions, forming a water mist liquid with a wide coverage area, a short spray distance and weak penetration. Among them, the smoke mode steps include: (B1) Start the telescopic adjustment structure of the outer sleeve, which drives the outer sleeve of the air guide tube to move forward away from the main body of the air guide tube, and stops moving after moving to a preset position. At this time, the front end of the inner tube of the air guide tube is located on the inner side of the outer sleeve of the air guide tube; start the steering gear, which drives the guide vane to rotate and close the guide vane. The multiple guide vanes are closed together to the preset position and then stop closing; (B2) Start the air duct fan. The high-speed airflow generated by the rotation of the air duct fan passes through the spoiler blades and moves along the outer cylindrical surface of the inner tube of the air duct; (B3) An external air source and an external oil source supply air and oil to the combustion chamber. 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 medicine liquid 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 medicine liquid in the tail pipe is cracked, broken and evaporated into fine droplets, forming a high-temperature smoke-like medicine liquid, which is discharged from the tail pipe outlet. The high-temperature smoke-like medicine liquid moves with the high-speed air flow generated by the rotation of the air duct fan; the air flow is constrained by the guide vane, and due to inertia, it gathers toward the center at a certain angle along the outer wall of the inner tube of the air duct, driving the smoke-like medicine liquid ejected from the tail pipe to gather toward the center, forming a smoke-like medicine liquid with a longer ejection distance, faster speed and stronger penetration.
