Description

Technical Field

[0001] The utility model relates to the field of pulse engine combustion, in particular to a multi-tail pipe structure for a pulse combustion smoke machine. Background Art

[0002] An ordinary pulse smoke machine utilizes the thermal energy, kinetic energy of the high-temperature gas generated by the operation of a pulse combustion engine, and the heat of a heated metal surface to cause the liquid oil-soluble medicine liquid to be violently evaporated and atomized at the medicine nozzle of the tail pipe. The high-speed airflow impacts the relatively static air outside, breaks and diffuses into smoke, and drifts with the natural airflow, thereby diffusing and penetrating into various parts of the prevention and control area. However, the amount of smoke released by the traditional smoke machine is determined by the flow rate of the supplied medicine and the energy of the high-speed airflow inside the tail pipe. The energy transferred from the combustion chamber to the tail pipe is limited. Only increasing the liquid medicine flow rate will result in poor crushing effect of the airflow on the liquid medicine, too large liquid droplets, and insufficient atomization, etc., which cannot meet the prevention and control requirements. Therefore, the amount of smoke released during operation is limited, resulting in limited prevention and control efficiency. At the same time, the smoke ejected runs slowly in the air and is easily affected by the air flow rate, which will greatly reduce the accuracy rate of the smoke machine for pesticide application. Considering the severity of current forestry pests and diseases and the need to meet the requirements of ecological environmental protection in pesticide application, it is of great significance to design a smoke machine that can improve the efficiency of forestry pest control by increasing the amount of smoke released during pesticide application and its running speed in the air. Summary of the Invention

A nut is threadedly connected to the pump air pipe, and the nut locks the spacer ring on the pump air pipe to the convex ring through a spring washer and a washer, and further locks the carburetor cover to the stop block on the pump air pipe through the flat gasket.

[0011] As a further improved technical solution of the present utility model, the oil inlet is connected to a pipe joint; the pump air pipe is connected to an external air pump.

[0012] As a further improved technical solution of the present utility model, the carburetor structure further includes a fuel needle valve structure. The fuel needle valve structure includes a knob, a spring and a fuel needle. A convex interface is provided on the carburetor body. One end of the fuel needle extends into the interior of the carburetor body through the through hole in the convex interface and points to the oil inlet. A retaining ring is provided around the outside of the fuel needle. A spring is sleeved on the outside of the fuel needle. The spring is located between the retaining ring and the inner plane in the through hole of the convex interface. The outside of the fuel needle is slidably and rotatably connected to a knob. The knob is located above the retaining ring and the knob contacts the retaining ring. One end of the knob is threadedly connected to the convex interface; a button is also fixedly connected to the top of the fuel needle.

[0017] The beneficial effects of the present utility model are as follows:

[0018] In the multi-tail pipe structure of the pulse combustion smoke machine of the present utility model, multiple tail pipes are evenly distributed around the combustion chamber in a circular pattern, and a corresponding medicine inlet pipe is arranged for each tail pipe. Multiple medicine inlet pipes can feed liquid simultaneously, greatly improving the medicine supply amount. At the same time, a Venturi tube with variable cross-section and variable aperture is added at the tail pipe to increase the air flow velocity at the gas-liquid contact area, so as to supplement the energy requirement for fragmentation, ensure the atomization effect of the liquid medicine, increase the velocity of the liquid medicine at the outlet of the tail pipe, avoid being affected by the surrounding air flow velocity, ensure the targeting and accuracy rate of the medicine application of the smoke machine, and is applicable to large-scale and dense agricultural and forestry crops with high coverage rate and high pesticide utilization rate.

[0019] When the present utility model is started, the air pump pumps air to supply air to the carburetor body and pressurize the fuel tank respectively. The combustible mixed gas flow formed by the carburetor body is ignited by the spark plug. The flame quickly spreads to the entire combustion chamber body, and the pressure in the combustion chamber body suddenly increases. The one-way intake diaphragm on the carburetor is closed, and the hot air flow after combustion can only be discharged from the tail pipe through the nozzle. The pressure in the combustion chamber body decreases, and the one-way intake diaphragm is opened to start intake. As the pressure in the combustion chamber further decreases, the air flow in the tail pipe changes from discharging outward to intake into the pipe, and the newly entered combustible mixture in the combustion chamber body is further compressed and ignited again, forming a cyclic process of periodic intake - combustion - emission. During the working process, the high-pressure air flow greater than the atmospheric pressure in the combustion stage in the combustion chamber body is continuously introduced into the medicine tank through the pump air pipe on the carburetor. When the medicine switch is opened, the liquid medicine in the medicine tank automatically flows into the tail pipe from the medicine inlet pipe on the tail pipe. In the tail pipe, when the high-temperature, high-frequency, and high-speed turbulent air flow passes through the reduced cross-sectional area in the Venturi tube section, the air flow shows an increase in velocity, and its velocity is inversely proportional to the cross-sectional area. At the same time, a low pressure will be generated near the high-speed flowing air flow, thus generating an adsorption effect. Using this effect, not only can the air flow velocity at the tail pipe be increased, but the low pressure generated by its high speed can also further absorb the liquid medicine in the medicine spray pipe, improve the medicine intake amount, increase the smoke emission amount (i.e., the medicine spray amount) of the smoke machine. Finally, under the disturbance of the high-temperature, high-frequency, and high-speed air flow, the liquid medicine is cracked, broken, and evaporated into fine droplets, enters the atmosphere from the outlet of the tail pipe, and condenses into visible smoke, which quickly diffuses, rises, and spreads to the prevention and control area.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] A multi-tail pipe structure for a pulse combustion smoke machine, as Figure 1-2 shown, includes a carburetor structure 1, a combustion chamber 2, a plurality of tail pipes 3, a medicine inlet tube 5 and a Venturi tube 4. The carburetor structure 1 is connected to the air inlet of the combustion chamber 2 through an air inlet pipe 6. The air outlet of the combustion chamber 2 is connected to a plurality of tail pipes 3 at the same time. Each tail pipe 3 is connected to a Venturi tube 4. As Figure 6 shown, a medicine inlet tube 5 is connected to each Venturi tube 4.

[0028] The medicine inlet tube 5 is connected to the tail of the contraction section 401 of the Venturi tube 4. The plurality of tail pipes 3 are circumferentially distributed and arranged in parallel.

[0029] In this embodiment, as Figure 1-5 shown, the carburetor structure 1 includes a carburetor cover 101, a pump air pipe 102, a one-way intake air diaphragm 106, a spacer 107 and a carburetor body 103.

[0030] The carburetor cover 101 is connected to the carburetor body 103. The connection method can be threaded or bolted connection, etc. A pump air pipe 102 is connected to the central through hole of the carburetor cover 101. A plurality of air inlets 1011 are provided on the surface of the carburetor cover 101; an oil inlet 1031 is provided on the carburetor body 103; the spacer 107 is sleeved on the pump air pipe 102, and a plurality of holes are provided on the spacer 107; both the spacer 107 and the one-way intake air diaphragm 106 are located between the carburetor cover 101 and the carburetor body 103.

[0031] As Figure 5As shown, a stopper 1021 is fixedly connected to the pump air pipe 102. The pump air pipe 102 passes through the central through-hole of the carburetor cover 101, and the stopper 1021 contacts the outer surface of the carburetor cover 101 through a flat gasket. A convex ring 1012 is provided around the inner side of the central through-hole of the carburetor cover 101. The one-way intake diaphragm 106 is sleeved on the convex ring 1012 and can move on the convex ring 1012. A nut 108 is threadedly connected to the pump air pipe 102. The nut 108 locks the spacer ring 107 on the pump air pipe 102 to the convex ring 1012 through a spring washer 109 and a washer, and further locks the carburetor cover 101 to the stopper 1021 on the pump air pipe 102 through the flat gasket.

[0032] In this embodiment, the one-way intake diaphragm 106 can move within a small gap between the carburetor cover 101 and the spacer ring 107, that is, it can block all the intake ports 1011 on the carburetor cover 101 or open the intake ports 1011 on the carburetor cover 101 under the action of air pressure. When the intake ports 1011 are opened, the intake ports 1011 can intake air.

[0033] In this embodiment, the fuel inlet 1031 is connected to a pipe joint 104; the pump air pipe 102 is connected to an external air pump. The external air pump is connected to a power source.

[0034] In this embodiment, as Figure 5 shown, the carburetor structure 1 further includes a fuel needle valve structure 105. The fuel needle valve structure 105 includes a knob 1052, a spring 1054 and a fuel needle 1053. A raised interface 1032 is provided on the carburetor body 103. One end of the fuel needle 1053 extends into the interior of the carburetor body 103 through the through-hole in the raised interface 1032 and points to the fuel inlet 1031. A retaining ring 10531 is provided on the outside of the fuel needle 1053. A spring 1054 is sleeved on the outside of the fuel needle 1053. The spring 1054 is located between the retaining ring 10531 and the inner plane 1033 in the through-hole of the raised interface 1032. A knob 1052 is slidably and rotatably connected to the outside of the fuel needle 1053. The knob 1052 is located above the retaining ring 10531 and the knob 1052 contacts the retaining ring 10531. One end of the knob 1052 is threadedly connected to the raised interface 1032; a button 1051 is also fixedly connected to the top of the fuel needle 1053.

[0035] In this embodiment, the end of the fuel needle 1053 is a conical structure.

[0036] In this embodiment, the knob 1052 includes a knob body and a plug. The knob body is connected to the plug through a set screw. The upper part of the plug is located inside the knob body. The plug is sleeved on the outside of the fuel needle 1053. The plug is slidably and rotatably connected to the fuel needle 1053. The plug contacts the retaining ring 10531 on the fuel needle 1053. The lower part of the plug is threadedly connected to the raised interface 1032.

[0037] When the oil needle valve structure 105 is in use, the button 1051 can be manually pressed to press the oil needle 1053. The oil needle 1053 moves downward inside the knob 1052 to block part of the oil inlet 1031, realizing the manual adjustment of the size of the oil inlet 1031 to adjust the oil intake. After releasing the hand, the oil needle 1053 resets under the action of the spring 1054. It is also possible to rotate the knob 1052. The knob 1052 rotates downward within the convex interface 1032. One end of the knob 1052 presses down the retaining ring 10531 of the oil needle 1053, thereby pressing down the oil needle 1053. The oil needle 1053 compresses the spring 1054 downward and then moves downward to block part of the oil inlet 1031. After adjusting to the required position, stop rotating the knob 1052. When the knob 1052 rotates in the reverse direction, the oil needle 1053 moves upward under the action of the spring 1054, and the size of the oil inlet 1031 can be increased. When oil enters through the oil inlet 1031, under the action of the air that rushes into the carburetor body 103 at high speed, the oil mixes with the air inside the carburetor body 103 to form a combustible mixture and flows through the combustion chamber 2.

[0038] In this embodiment, the carburetor structure 1 is connected to the combustion chamber 2 through the intake pipe 6. A first pressure guiding pipe 7 is connected to the intake pipe 6. The first pressure guiding pipe 7 is connected to an external fuel tank. The external fuel tank is communicated with an external fuel tank float chamber. The external fuel tank float chamber is connected to the oil inlet 1031 on the carburetor body 103 through a pipe joint 104. A second pressure guiding pipe 8 is connected to the combustion chamber 2. The second pressure guiding pipe 8 is connected to an external medicine tank. The external medicine tank is connected to the medicine inlet pipe 5. A spark plug is arranged inside the intake pipe 6.

[0039] In this embodiment, the sum of the cross-sectional areas of all the tail pipes 3 is greater than the cross-sectional area of the intake pipe 6.

[0040] In this embodiment, the combustion chamber 2 includes a gland 202 and a combustion chamber body 201. The gland 202 is connected to the combustion chamber body 201 by bolts.

[0041] When the present invention starts, an air pump pumps air to supply the carburetor body 103 respectively. The gas then passes through the first pressure guiding pipe 7 at the intake pipe 6, and pressurizes the external fuel tank through the first pressure guiding pipe 7 and the pipeline. After the gasoline in the float chamber of the external fuel tank is pressurized, it enters the inside of the carburetor body 103 through the pipe joint 104 and the fuel inlet 1031. The external air pump rushes the external air into the inside of the carburetor body 103 at a high speed through the pump air pipe 102. The gasoline mixes with the air inside the carburetor body 103 to form a combustible mixture (containing gasoline particles) and flows through the combustion chamber 2, and is ignited by the spark plug. The flame rapidly spreads throughout the combustion chamber 2, and the pressure in the combustion chamber 2 suddenly increases. The high-pressure gas generated makes the one-way intake diaphragm 106 tightly adhere to the carburetor cover 101 to seal the air inlet 1011 on the carburetor cover 101. The hot air flow after combustion can only be discharged from the tail pipe 3 through the nozzle. The pressure in the combustion chamber 2 drops, and the one-way intake diaphragm 106 opens the air inlet 1011 on the carburetor cover 101. The air inlet 1011 on the carburetor cover 101 starts to intake air, that is, the carburetor body 103 starts to suck air. The gasoline mixes with the air entering through the air inlet 1011 inside the carburetor body 103 to form a combustible mixture. As the pressure in the combustion chamber 2 further drops, the air flow in the tail pipe 3 changes from discharging outwards to intake air inside the pipe. The combustible mixture just entering the combustion chamber 2 is further compressed and ignited again, forming a cyclic process of intake - combustion - emission. During the working process, the second pressure guiding pipe 8 on the combustion chamber 2 continuously introduces the high-pressure air flow greater than the atmospheric pressure in the combustion stage inside the combustion chamber 2 into the external medicine box. When the medicine supply switch on the pipeline between the external medicine box and the second pressure guiding pipe 8 is opened, the liquid medicine in the external medicine box automatically flows into the Venturi tube 4 from the medicine inlet pipe 5. In the tail pipe 3, when the high-temperature, high-frequency, high-speed turbulent air flow passes through the reduced cross-sectional area of the Venturi tube 4 section, the air flow shows a phenomenon of increasing flow velocity. Its flow velocity is inversely proportional to the cross-sectional area of the flow-through section. At the same time, a low pressure will be generated near the high-speed flowing air flow, thus generating an adsorption effect. Using this effect, not only can the flow velocity of the air flow in the Venturi tube 4 be increased, but the low pressure generated by its high speed can also further absorb the liquid medicine in the medicine inlet pipe to increase the medicine intake. Finally, under the action of the high-temperature, high-frequency, high-speed air flow disturbance, the liquid medicine is cracked, broken, and evaporated into fine mist droplets, enters the atmosphere from the outlet of the Venturi tube 4, and condenses into visible smoke, which quickly diffuses, rises, and spreads to the prevention and control area. After the first combustion, the external air pump can stop supplying air to the pump air pipe 102, which is specifically set according to the actual situation. The gas required during the subsequent cyclic combustion process is realized by intake air through the air inlet 1011 on the carburetor cover 101. During the subsequent cyclic combustion process, the high-pressure air flow greater than the atmospheric pressure in the combustion stage can also be introduced into the external fuel tank through the first pressure guiding pipe 7 to pressurize the external fuel tank, and further make the float chamber of the external fuel tank supply fuel to the fuel inlet 1031 through the pipe joint 104.

[0042] The utility model is used in a multi-tailpipe structure of a pulse combustion smoke machine. There are multiple tailpipes 3 circumferentially distributed in the combustion chamber 2, and a corresponding medicine inlet pipe 5 is arranged for each tailpipe 3. The multiple medicine inlet pipes 5 can feed liquid simultaneously, greatly improving the medicine supply amount. At the same time, a Venturi tube 4 with variable cross-section and variable aperture is added at the tailpipe 3 to increase the air flow velocity at the gas-liquid contact point, so as to supplement the energy requirement for fragmentation, ensure the atomization effect of the liquid medicine, increase the velocity of the liquid medicine at the outlet of the tailpipe 3, be free from the influence of the surrounding air flow velocity, ensure the targeting and accuracy rate of the smoke machine for pesticide application, and is applicable to large-scale and dense agricultural and forestry crops with high coverage rate and high pesticide utilization rate.
