[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the scheme of this application:

[0019] 1. Through the set pressing kit, because the pressing kit wraps the rotating nozzle inside, the higher the height of the pressing kit, the greater the spraying angle. Because the inner arc surface of the pressing kit is provided with internal teeth and springs, the spiral turns of the spring will be stuck at the lower part of the internal teeth when deformed, and the wrapping range of the pressing kit can be determined according to the height of the drone to fly. Because the higher the height, the faster the air flow rate at the top. If the spraying range is expanded, most of the liquid will float in the opposite direction with the wind, which is not only wasteful but also affects the spraying range. Therefore, the flight altitude is lowered and the spraying angle is controlled, so that the expanded spraying becomes a concentrated range operation, which can not only control the spraying range, but also operate within the normal working range of the drone;

[0020] 2. The rotating nozzle can not only control the water flow, but also guide the water to the appropriate position of the vegetation, because the dispersed small water columns will flow into the micro grooves along the holes, and the width between the micro grooves is between 1 and 3 mm. Since the lengths of the micro grooves are different, water flows of different lengths are created. When the water pressure is strong enough, the rotating nozzle starts to rotate, and the sprayed pesticides will be distributed over a large area of ​​the vegetation, and the sprayed pesticides will be evenly distributed in every corner to avoid waste;

[0021] 3. The aluminum gasket has a high thermal conductivity, which can quickly transfer heat from the inside to the outside surface to improve the heat dissipation efficiency. It also has a low thermal inertia as a shell. Even in a high temperature environment, it can quickly dissipate heat and reduce the temperature of the hybrid engine. At the same time, because the aluminum gasket is relatively light, it will not increase the resistance to the take-off of the drone and affect the flight attitude of the drone.

[0022] 4. The processor water-cooling pump is set up to absorb the heat energy generated by the combustion chamber using cooling water, and at the same time drive the cooling water to make the cooling water that absorbs the heat energy flow to the water-cooling row through the conduit A, so as to transfer the heat energy to the water-cooling row for heat dissipation. Under the continuous driving of the processor water-cooling pump, the cooling water cooled by the metal heat sink fins in the water-cooling row flows to the internal connecting water port through the conduit B. The cooling water in the connecting water port absorbs the heat energy generated by the aluminum gasket in the liquid guide groove, and under the driving of the processor water-cooling pump, flows back to the processor water-cooling pump through the conduit C, thereby reducing the evaporation of pesticides inside the drone due to the heat of the engine.

[0023] 5. The connection between the provided conduits can be connected to the water injection pipe. Low temperature treatment of pesticides can effectively slow down the chemical reaction in the pesticides, thereby ensuring the stability and activity of the pesticides during storage, and reducing the residual amount and negative impact of pesticides in the environment.

[0047] See also Figures 1 to 10 The present invention provides a technical solution: a hybrid plant protection drone for pesticide spraying.

[0048] Embodiment 1:

[0049] like Figure 1 , Figure 2 ,and Fig. 9 As shown, the present embodiment proposes an oil-electric hybrid plant protection UAV for pesticide spraying, comprising a fuselage 1, a storage cavity 101 is provided at one edge of the upper surface of the fuselage 1, a tripod 102 is fixedly installed on both sides of the fuselage 1 by bolts, a connecting arm 103 is fixedly installed in the middle of the fuselage 1 close to the tripod 102, one end of the connecting arm 103 is provided with a through hole, a connecting pillar 104 is penetrated and connected in the through hole of the connecting arm 103, L-shaped fixing seats 105 are fixedly installed at both ends of the connecting pillar 104, a motor 106 is fixedly installed on the upper surface of the L-shaped fixing seat 105, a propeller 107 is fixedly installed at the output end of the motor 106, a rectangular through groove is opened on one side of the L-shaped fixing seat 105, a nozzle bracket 2 is penetrated and connected in the rectangular through groove on one side of the L-shaped fixing seat 105, a mounting block 3 is slidably clamped on the upper surface of the nozzle bracket 2, and a spraying assembly 4 is fixedly installed on the lower surface of the mounting block 3 by bolts.

[0050] In this embodiment, when the hybrid UAV is working, the initial battery 603 will provide the UAV with electric energy for the flight of the UAV. The current detection on the battery 603 detects the current output value of the battery 603 at any time. When the current output value is lower than the minimum current value required by the UAV, the current detection controls the electric valve to work, and the electric valve opens the switch set on the hybrid motor 6. The hybrid motor 6 starts to work, and the oil pump draws the oil in the oil tank into the combustion chamber 601 to generate electricity. The combustion chamber 601 converts the chemical energy of the gasoline into the electric energy required by the UAV, and provides it to the UAV through the electric plug. In this way, the hybrid UAV 6 can meet the function of providing a long endurance, improve operating efficiency, and reduce operating costs.

[0051] Embodiment 2:

[0052] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the spray assembly 4 includes an angular block 41 fixedly mounted on the lower surface of the mounting block 3, quick-release joints 42 are penetrated and connected on both sides of the angular block 41, and a nozzle 43 is movably connected to the inner arc surface of the quick-release joint 42, and a water injection pipe 44 is fixedly mounted on the lower surface of the angular block 41 by bolts, and a micro-injection pipe 45 is movably connected to one end of the water injection pipe 44, and a connecting kit 46 is penetrated and connected to the outer arc surface of the micro-injection pipe 45, and a serrated end is provided at one end of the connecting kit 46, and a convex sleeve 48 is movably clamped to the serrated end on one side of the connecting kit 46, and a rubber gasket 49 is fixedly mounted on the lower surface of the convex sleeve 48, and a spring 410 is movably overlapped in the middle of the lower surface of the rubber gasket 49, and a pressing kit 411 is fixedly mounted on one end of the spring 410.

[0054] In this embodiment, the nozzle 43 is fixed on the bracket by relying on the mounting block 3 under the length limit of the nozzle bracket 2, and is connected to the water injection pipe 44 through the angle block 41 under the mounting block 3. The nozzle bracket 2 and the quick-release joint 42 are first connected to the nozzle 43 with nuts and gaskets. After the quick-release joint 42 is connected to the nozzle 43, the nozzle 43 is clamped inwardly due to the elastic parts arranged inside. The connecting thread at the quick-release joint 42 must be wrapped with sealing filler to ensure the sealing of the nozzle connection assembly.

[0055] Among them, a micro-injection tube 45 is installed in the water injection pipe 44 connected to the nozzle 43. During the pesticide spraying process, it is not sprayed downward in a columnar manner, but vegetation operations are carried out in a mist form. Therefore, when the water flows into the micro-injection tube 45 from the larger diameter pipe of the water injection pipe 44, the water will slowly flow into the micro-injection tube 45. At the same time, in order to prevent the inside of the water injection pipe 44 from being blocked, or to observe the pesticide composition, the connecting kit 46 can be rotated to separate the teeth on the convex sleeve 48, so that the situation inside the pipe can be observed, so that the pesticide composition in the pipe can be observed on site, and the end of the nozzle 43 is connected to the fuselage 1, and a cavity is provided inside the fuselage 1 to place the pesticide inside it, so as to facilitate replacement.

[0056] Secondly, the connection of the rubber gasket 49 is to enhance the sealing effect, and the spring 410 under the connected pressing kit 411 plays an auxiliary role. Because the rotating nozzle 55 is wrapped inside the pressing kit 411, the higher the height of the pressing kit 411, the greater the spraying angle. Because the inner arc surface of the pressing kit 411 is provided with internal teeth and connected to the spring 410, the spiral turns of the spring 410 will be stuck in the lower part of the internal teeth when deformed, and the wrapping range of the pressing kit 411 can be determined according to the altitude of the UAV to be flown, because the higher the altitude, the faster the air flow rate at the top. If the spraying range is expanded, most of the liquid medicine will float in the opposite direction with the wind, which is not only wasteful but also affects the spraying range. Therefore, the flight altitude is lowered and the spraying angle is controlled to turn the expanded spraying into a concentrated range operation, which can not only control the spraying range, but also operate within the normal working range of the UAV.

[0057] like Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, one end of the micro-injection tube 45 is penetrated and connected with a nozzle assembly 5, and the nozzle assembly 5 includes a transparent silicone member 51 penetrated and connected to one end of the micro-injection tube 45, and the inner arc surface of the micro-injection tube 45 close to the transparent silicone member 51 is movably sleeved with a diverter cone 52, and the outer arc surface of the diverter cone 52 is provided with a drainage groove 53, and the bottom of the outer arc surface of the diverter cone 52 is movably sleeved with a sealing gasket 54, and the outer arc surface of the sealing gasket 54 is annularly sleeved with a rotating nozzle 55, and the rotating nozzle 55 is a conical structure, and the outer arc surface of the rotating nozzle 55 is provided with micro grooves 56, and the number of micro grooves 56 is several, and they are evenly distributed on the outer arc surface of the rotating nozzle 55 in the form of a circular array, and the number of rotating nozzles 55 is four, and they are symmetrically distributed on both sides of the fuselage 1 in groups of two.

[0058] In this embodiment, each nozzle assembly 5 connected to the micro-injection tube 45 can achieve spraying at a longer distance, so the micro-injection tube 45 first transports the pesticide to the diversion cone 52, and the drainage groove 53 on the peripheral side is used to divide the pesticide into groups of small water columns. This purpose can not only spray around the rotating nozzle 55 without dead angles, but also reduce the damage to the internal parts caused by the water pressure.

[0059] Among them, the rotating nozzle 55 can not only control the water flow, but also guide the water to be sprayed to the appropriate position of the vegetation. The reason why it can pass through the micro grooves 56 is that the scattered small water columns will flow along the holes to the inside of the micro grooves 56, and the width between the micro grooves 56 is between 1 and 3 mm. Since the lengths of the micro grooves 56 are different, water flows of different lengths are created. When the water pressure is strong enough, the rotating nozzle 55 starts to rotate, and the sprayed pesticides will be distributed over a large area throughout the vegetation, and the sprayed pesticides will be evenly distributed in every corner to avoid waste.

[0060] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a hybrid motor 6 is fixedly mounted on the lower surface of the fuselage 1, combustion chambers 601 are provided on both sides of the outer shell of the hybrid motor 6, a connecting shaft seat 602 is provided at the bottom of the combustion chamber 601, a refrigeration assembly 7 is fixedly mounted on the lower surface of the connecting shaft seat 602, the refrigeration assembly 7 includes an aluminum gasket 71 fixedly mounted on the connecting shaft seat 602, a battery 603 is provided on one side of the hybrid motor 6, the number of the aluminum gaskets 71 is two, a shell 72 is fixedly mounted on one side of the two aluminum gaskets 71, a connecting water port 73 is provided at the bottom of one side of the shell 72, a liquid cooling plate 74 is fixedly mounted on the middle of the shell 72, and liquid guide grooves 75 are provided on the upper and lower surfaces of the liquid cooling plate 74.

[0061] In this embodiment, two aluminum gaskets 71 are used to sandwich the internal liquid cooling plate 74. The aluminum gasket 71 not only has a high thermal conductivity, which can quickly transfer heat from the inside to the external surface to improve the heat dissipation efficiency, but also has a low thermal inertia as a shell. Even in a high temperature environment, it can quickly dissipate heat and reduce the temperature of the hybrid engine 6. At the same time, because the aluminum gasket 71 is relatively light, it will not increase the resistance to the take-off of the drone and affect the flight posture of the drone.

[0062] The liquid guide groove 75 inside the liquid cooling plate 74 pours the coolant into it through the connecting water inlet 73, and the flowing coolant is carried to the aluminum gasket 71 for heat exchange, and finally the liquid cooled by the heat exchange is sent to the water cooling radiator 76, thus realizing a single-channel circulation.

[0063] like Figure 7 , Figure 8 and Fig.10 As shown, as a preferred embodiment, on the basis of the above method, further, a water-cooling radiator 76 is fixedly installed at the edge of one side of the upper surface of the aluminum gasket 71, a metal heat dissipation fin 77 is fixedly installed on the inner wall of the water-cooling radiator 76, a first joint 78 and a second joint 79 are connected at the edge of one side of the water-cooling radiator 76, a processor water-cooling pump 710 is fixedly installed on the side of the aluminum gasket 71 close to the water-cooling radiator 76, the same joint is provided on one side of the processor water-cooling pump 710, a conduit A711 is connected to the joint on one side of the processor water-cooling pump 710, one end of the conduit A711 away from the processor water-cooling pump 710 is fixedly installed in the first joint 78, one end of the second joint 79 is fixedly installed with a conduit B712, one end of the conduit B712 is fixedly installed in one of the connecting water outlets 73, the joint of the processor water-cooling pump 710 is connected with a conduit C713, and one end of the conduit C713 is fixedly installed on the other connecting water outlet 73.

[0064] In this embodiment, the processor water-cooling pump 710 utilizes cooling water to absorb the heat energy generated by the combustion chamber 601, and at the same time drives the cooling water so that the cooling water that absorbs the heat energy flows to the water-cooling row 76 through the conduit A711, so as to transfer the heat energy to the water-cooling row 76 for heat dissipation. Under the continuous driving of the processor water-cooling pump 710, the cooling water that is cooled by the metal heat dissipation fins 77 in the water-cooling row 76 flows to the internal connecting water port 73 through the conduit B712. The cooling water in the connecting water port 73 absorbs the heat energy generated by the aluminum gasket 71 in the liquid guide groove 75, and under the driving of the processor water-cooling pump 710, flows back to the processor water-cooling pump 710 through the conduit C713 to complete the cooling water circulation. In addition, the cooling water can also circulate in the opposite direction of the above-mentioned flow direction.

[0065] Among them, the entire aluminum gasket 71 is fixedly connected to the combustion chamber 601, so the heat generated by the combustion of the engine will be absorbed by the aluminum gasket 71 at the bottom. At the same time, the water cooling radiator 76 is placed in front of the drone to generate convection air during the flight, which further cools the metal cooling fins 77. In addition, the connection between each conduit can be connected to the water injection pipe 44. The low-temperature treatment of pesticides can effectively slow down the chemical reaction in the pesticides, thereby ensuring the stability and activity of the pesticides during storage, and can reduce the residual amount and negative impact of pesticides in the environment.

[0066] Embodiment 3:

[0067] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0068] Specifically, a hybrid plant protection drone for pesticide spraying is working / in use: when the hybrid drone is working, the initial battery 603 will provide power to the drone for flight, and the current detection on the battery 603 detects the current output value of the battery 603 at any time. When the current output value is lower than the minimum current value required by the drone, the current detection controls the electric valve to work, and the electric valve opens the switch set on the hybrid motor 6, and the hybrid motor 6 starts to work. The oil pump draws the oil in the oil tank into the combustion chamber 601 to generate electricity. The combustion chamber 601 converts the chemical energy of the gasoline into the electrical energy required by the drone, and provides it to the drone through the electric plug, so that the hybrid motor 6 drone can meet the function of providing a long endurance and improve the operation efficiency. The spray head bracket 2 is fixed on the bracket by the mounting block 3 under the length limit, and is connected to the water injection pipe 44 through the angle block 41 under the mounting block 3. The spray head bracket 2 and the quick-release joint 42 are first connected to the nozzle 43 with nuts and gaskets. After the quick-release joint 42 is connected to the nozzle 43, the nozzle 43 is clamped inwardly by the elastic member arranged inside. The connecting thread at the quick-release joint 42 should be wrapped with sealing filler to ensure the sealing of the spray head connection assembly. A micro-injection pipe 45 is installed in the water injection pipe 44 connected to the nozzle 43. During the pesticide spraying process, it is not sprayed downward in a columnar manner, but the vegetation operation is carried out in a mist form. Therefore, when the water flows into the micro-injection pipe 45 from the pipe with a larger diameter of the water injection pipe 44, it will flow slowly. Into the micro-injection tube 45, at the same time, in order to prevent the inside of the water injection tube 44 from being blocked, or to observe the pesticide composition, the connection kit 46 can be rotated to separate the teeth on the convex sleeve 48, so that the situation inside the tube can be observed, so that the pesticide composition in the tube can be observed on site, and the end of the nozzle 43 is connected to the fuselage 1. The interior of the fuselage 1 is provided with a cavity to place the pesticide inside it, so as to facilitate replacement, and the spring 410 under the connected pressing kit 411 plays an auxiliary role. Because the rotating nozzle 55 is wrapped inside the pressing kit 411, the higher the height of the pressing kit 411, the greater the spraying angle, because the inner arc surface of the pressing kit 411 is provided with internal teeth and connected to the spring 410, the spiral turns of the spring 410 will be stuck at the lower part of the internal teeth when deformed. , and the package range of the pressing kit 411 can be determined according to the altitude at which the drone is to fly, because the higher the altitude, the faster the air flow rate at the top. If the spraying range is expanded, most of the liquid medicine will float in the opposite direction with the wind, which is not only wasteful but also affects the spraying range. Therefore, the flight altitude is lowered and the spraying angle is controlled to make the expanded spraying become a concentrated range operation, which can not only control the spraying range, but also operate within the normal working range of the drone. The various nozzle assemblies 5 connected by the micro-injection tube 45 can achieve long-distance spraying, so the micro-injection tube 45 first transports the pesticide to the diversion cone 52, and the drainage groove 53 on the peripheral side is to divide the pesticide into groups of small water columns. This purpose can not only spray around the rotating nozzle 55 without dead angles,It can also reduce the damage to internal parts caused by water pressure, and the rotating nozzle 55 can not only control the water flow, but also guide the water to the appropriate position of the vegetation. The reason why it can pass through the micro groove 56 is that the scattered small water columns will flow along the holes to the inside of the micro groove 56, and the width between the micro grooves 56 is between 1 and 3 mm. Since the lengths of the micro grooves 56 are different, water flows of different lengths are created. When the water pressure is strong enough, the rotating nozzle starts to rotate, and the sprayed pesticides will be distributed over a large area throughout the vegetation, and the sprayed pesticides are evenly distributed in every corner to avoid waste. The processor water cooling pump 710 uses cooling water to absorb the heat energy generated by the combustion chamber 601, and at the same time drives the cooling water to make the cooling water that absorbs the heat energy flow through the conduit A711 to the water cooling row 76, so as to transfer the heat energy to the water cooling row 76 for heat dissipation. Under the continuous drive of the processor water cooling pump 710, the metal heat dissipation fins 77 in the water cooling row 76 are The cooling water for heat dissipation and temperature reduction flows to the internal connecting water port 73 through the conduit B712. The cooling water in the connecting water port 73 absorbs the heat energy generated by the aluminum gasket 71 in the liquid guide groove 75, and under the drive of the processor water cooling pump 710, flows back to the processor water cooling pump 710 through the conduit C713 to complete the cooling water cycle. In addition, the cooling water can also circulate in the opposite direction of the above-mentioned flow direction, and the entire aluminum gasket 71 is fixedly connected to the combustion chamber 601, so the heat generated by the combustion of the engine will be absorbed by the aluminum gasket 71 at the bottom. At the same time, the water cooling row 76 is placed in front of the drone, and convective air is generated during the flight, which further cools the metal heat dissipation fins 77. In addition, the connection between each conduit can be connected to the water injection pipe 44. Because the low-temperature treatment of pesticides can effectively slow down the chemical reaction in the pesticides, thereby ensuring the stability and activity of the pesticides during storage, it can reduce the residual amount and negative impact of the pesticides in the environment. ,
