The air-assisted orchard spraying device of the present invention is provided with an air-assisted spray head and a blower, so that the airflow provided by the blower can carry the medicine mist through the spray head for spraying, so that the medicine mist can be sprayed to a higher tree canopy. The sprayer relies on the strong airflow of the terminal nozzle to blow the droplets to various parts of the plant canopy. The airflow helps to increase the range of the orchard sprayer, assist the droplets to penetrate the dense canopy and promote the leaves to flip, thereby increasing the leaf attachment rate.

[0004] When spraying the tree crown, in order to ensure a good leaf adhesion rate, the spraying angle of the sprayer needs to be adjusted manually so that it can cover a larger spraying range. The angle of the sprayer is fixed and needs to be adjusted manually to ensure a good spraying range.

[0005] And because the sprayer is located closer to the bottom crown, when spraying the top crown, the spraying distance of the top crown is longer, and the spraying intensity is the same as that of the bottom crown, resulting in different spraying effects between the top crown and the bottom crown.

DETAILED DESCRIPTION

[0074] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. And if it is possible to implement, the features of different embodiments can be applied interchangeably.

[0075] Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, which can be understood by those familiar with this field. Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted in the content of this specification as consistent with the meanings of the relevant fields of the present invention. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal meanings.

[0076] See also Figure 1-Figure 18 The present invention provides a crown multi-operation mode sprayer, which performs spraying operations on the crown to ensure the spraying status of the bottom crown and the top crown.

[0077] In one embodiment, the sprayer comprises:

[0078] The box body 1 has a plurality of thread grooves 11 on the top thereof for mounting the bottle body, a top cone 12 is arranged inside the thread groove 11, and a magnetic member 13 is arranged inside the top cone 12 to control the top cone 12;

[0079] A metering unit 14 is disposed outside the top cone 12, and is used to measure the dosage of the medicine, and the metering unit 14 is used to control the state of the magnetic member 13;

[0080] A plurality of connection ends 2 are arranged outside the box body 1, the connection ends 2 are connected to the box body 1, and an adjustable spraying rod 3 is installed outside the connection end 2, a spray head 4 is arranged inside the spraying rod 3, and the spraying rod 3 is a two-stage structure and can be disassembled and replaced;

[0081] The connecting structure 5 is installed outside the box body 1 and controls the spraying angle of the spraying rod 3;

[0082] A pressure balance component 6 is installed inside the box 1 and communicated with the connection structure 5. The connection structure 5 moves to adjust the pressure state inside the box 1 through the pressure balance component 6;

[0083] The control terminal 7 is independently provided and used to control the connection structure 5 and remotely adjust the spraying angle of the spraying rod 3 .

[0084] In this embodiment, since the pressure state inside the box 1 directly affects the pressure of the liquid entering the spray rod 3, the greater the pressure inside the box 1, the longer the movement path of the liquid sprayed by the spray rod 3. When spraying the top crown from the ground, a greater spraying intensity can be obtained, ensuring that the top crown has the same spraying effect as the bottom crown.

[0085] The metering unit 14 is used to measure the amount of pesticide. When in use, the pesticide bottle is installed on the outside of the box 1. When in use, the amount of pesticide can be automatically measured, so as to ensure the accuracy of the added amount. Before the pesticide is unpacked, the inside of the bottle is coated to seal the bottle. Therefore, the movement of the top cone 12 is used to open the seal of the bottle to allow the pesticide to flow out.

[0086] Optionally, the top of the box 1 is a mounting platform that can be rotated and adjusted in angle. The top cone 12, the magnetic part 13 and the metering unit 14 are all installed on the mounting platform. When the metering unit 14 measures pesticides, the bottle body is located on the top of the box 1 with the bottle mouth facing downward. When the bottle body is removed after the metering is completed, the mounting platform swings and the bottle body is located on the side of the box 1 to avoid spilling of pesticides in the bottle due to disassembly. The magnetic part 13 is an electromagnet.

[0087] Alternatively, since the pesticide bottle may not match the threaded groove 11 when the pesticide is replaced for spraying, a rubber ring is provided inside the threaded groove 11 to connect the bottle and ensure the stability of the bottle.

[0088] The flow meter, when in use, obtains the amount of liquid flowing out of the pesticide bottle through the flow meter. When the magnetic part 13 is separated from the adsorption of the top cone 12, the top cone 12 seals the bottle mouth. The magnetic part 13 is an electromagnet and a supporting spring.

[0089] In one embodiment, the connection end 2 is connected to the inside of the box body 1 at the bottom of the box body 1, and the connection end 2 is connected to the spraying rod 3, and the spraying rod 3 has a two-stage structure:

[0090] One is a moving head 31 detachably mounted on the connecting section. The moving head 31 is detachably mounted on the inner side of the connecting end 2, and the moving head 31 is connected to the connecting structure 5 and driven by the connecting structure 5 to change the angle.

[0091] The second is a rod body 32 detachably connected to the moving head 31 . The rod body 32 and the moving head 31 are detachably plugged in each other, and a positioning groove 33 is disposed on the outer surface of the rod body 32 , while a positioning protrusion 34 is disposed on the inner side of the moving head 31 .

[0092] In this embodiment, the spray rod 3 is split into a moving head 31 and a rod body 32, which can facilitate the replacement of the rod body 32. The rod body 32 and the moving head 31 are detachably installed. Therefore, the spraying state of the rod body 32 can be changed by replacing the rod body 32, so that the rod body 32 can be adjusted accordingly according to different tree crown shapes.

[0093] The moving head 31 and the connecting end 2 are installed through a sealed connection, and the swing range of the moving head 31 is 90°. Therefore, the installation position of the moving head 31 and the connecting end 2 is sealed by multiple sealing rings to avoid leakage of the sprayed liquid.

[0094] In one embodiment, the rod body 32 is a straight rod, and the rod body 32 includes:

[0095] A plurality of straight tube bodies a21 are arranged in a sleeve arrangement, a sealing head a22 is arranged between two adjacent straight tube bodies a21 to form a seal between the straight tube bodies a21, and a nozzle 4 is installed outside the outermost straight tube body a21;

[0096] The sealing strip a23 is fixed to the outer wall of the inner straight tube body a21. A through hole a25 with different apertures is opened in the middle of the sealing strip a23. The through hole a25 extends to the inside of the straight tube body a21. The innermost straight tube body a21 is sealed and installed with an adjusting head a24. The adjusting head a24 rotates to connect the through holes a25 with different apertures with the nozzle 4.

[0097] In this embodiment, through holes a25 of different apertures are provided to adjust the spraying state of the nozzle 4, and the spraying state of the nozzle 4 is related to the water pressure and flow rate inside the box 1, and the water pressure inside the box 1 is a fixed value. The combination of through holes a25 of different apertures changes the size of the cross-sectional area. According to the basic principles of fluid mechanics, the flow rate is related to the cross-sectional area and flow rate of the pipeline. Under the same pressure, the larger the aperture, the greater the flow rate. Therefore, the spraying state of the nozzle 4 will be changed.

[0098] Among them, the positioning groove 33 is opened on the outside of the outermost straight tube body a21. Therefore, the outermost straight tube body a21 is internally restricted, and the rotation of the inner straight tube body a21 will change the position of the sealing strip a23, so that the sealing strip a23 with through holes a25 of different apertures moves to the position of the nozzle 4 and connects with the nozzle 4.

[0099] In one embodiment, the rod body 32 is an arc rod, and the rod body 32 includes:

[0100] A plurality of mutually nested arc tubes b21, a sealing member b22 is provided between two adjacent arc tubes b21, and one end of the innermost arc tube b21 is sealed, and the nozzles 4 are evenly installed inside the arc tubes b21;

[0101] The arc tube b21 is pulled out to extend in an arc shape, and a sealed cavity b23 is formed between the sealing members b22. The arc tube b21 is pulled out to change the internal pressure of the sealed cavity b23.

[0102] The apertures of the nozzles 4 installed from the inside to the outside of the arc tube b21 increase from small to large.

[0103] In this embodiment, the rod body 32 is set as an arc rod. When the arc tube body b21 is extended, the arc tube body b21 can form an arc range, so that spraying operations can be carried out on small tree crowns. The arc range can cover a larger small tree crown range, avoiding the problem of a straight rod causing part of the liquid to be sprayed on the outside of the tree crown.

[0104] In one embodiment, a nut 35 is arranged between the moving head 31 and the rod body 32 for fixing the moving head 31 and the rod body 32. A plurality of pits 36 are arranged on the outer wall of the rod body 32. The inner side of the nut 35 is conically arranged and threadedly connected to the moving head 31. A ball 37 is arranged on the conical surface inside the nut 35. The conical surface, the ball 37 and the pit 36 ​​cooperate to form an extrusion fixation for the rod body 32.

[0105] In this embodiment, the nut 35 is restricted to the outside of the rod body 32 and cannot be removed. When disassembling, the connection between the nut 35 and the moving head 31 is detached, and the rod body 32 is pulled out from the inside of the moving head 31, thereby facilitating the replacement of the rod body 32.

[0106] Among them, a solenoid valve is set in the middle of the connecting end 2, and the solenoid valve is used to control the connection state between the moving head 31 and the box body 1. When the solenoid valve is closed, the moving head 31 is not connected with the box body 1, and the solenoid valve is controlled by the control end 7.

[0107] In one embodiment, the connection structure 5 comprises:

[0108] A fixing frame 51 is detachably mounted on the outer side of the box body 1. A driving structure 52 is disposed inside the fixing frame 51. The driving structure 52 is detachably mounted inside the fixing frame 51 and controls the swing angle of the moving head 31 through a transmission structure 53.

[0109] The transmission structure 53 includes a slide bar 531 and a transmission wheel 532 on both sides of the slide bar 531 and meshing with the slide bar 531 for transmission. The slide bar 531 can be slidably installed on the inner side of the fixed frame 51. A guide groove for limiting the slide bar 531 is arranged inside the fixed frame 51. The slide bar 531 slides inside the guide groove. When the slide bar 531 is located at both ends of the guide groove, the spraying rod 3 is located in the extreme swing range.

[0110] In this embodiment, the transmission structure 53 is driven by the driving structure 52, and the position of the spraying rod 3 is adjusted by the movement of the transmission structure 53. The driving structure 52 is started by the control terminal 7, so that the position of the spraying rod 3 can be remotely controlled.

[0111] The guide groove limits the position of the slide bar 531 so that the slide bar 531 can only slide inside the guide groove without falling. The transmission wheel 532 located outside the moving head 31 is fixedly sleeved on the outside of the moving head 31 and drives the moving head 31 to rotate.

[0112] In one embodiment, the pressure balance assembly 6 comprises:

[0113] The top pressure chamber 61 and the bottom pressure chamber 62 are fixed to the outside of the box body 1, and a connecting structure 63 is provided between the top pressure chamber 61 and the bottom pressure chamber 62 to control the connection between the top pressure chamber 61 and the bottom pressure chamber 62, and the connecting structure 63 limits the gas flow speed between the top pressure chamber 61 and the bottom pressure chamber 62;

[0114] The top pressure chamber 61 and the bottom pressure chamber 62 are both provided with an electromagnetic plate 64, which is swingably provided on the outer wall of the box body 1, and the top pressure chamber 61 and the bottom pressure chamber 62 are both provided with a flexible surface close to the electromagnetic plate 64;

[0115] An electromagnetic block 65 is disposed at one end of the electromagnetic plate 64 close to the outer wall of the box body 1, and the electromagnetic block 65 controls the swing angle of the electromagnetic plate 64;

[0116] The top pressure chamber 61 and the bottom pressure chamber 62 are both internally provided with elastic members 66 for supporting the electromagnetic plates 64 .

[0117] In this embodiment, the electromagnetic plate 64 is used to squeeze the pressure chamber, causing it to shrink. The shrinkage of the pressure chamber increases the pressure inside the pressure chamber. The increased pressure inside the pressure chamber can increase the pressure inside the box body 1, so that the inside of the box body 1 has a higher pressure to cause the liquid inside the box body 1 to be ejected.

[0118] Optionally, the elastic member 66 is a support spring. In order to prevent the support spring from damaging the pressure chamber, flexible rubber is disposed at both ends of the pressure spring, and the flexible rubber is connected to the inner wall of the pressure chamber.

[0119] The pressure chamber is composed of two structures. The position in contact with the electromagnetic plate 64 is set as a flexible structure, which can squeeze the pressure chamber during the swing of the electromagnetic plate 64, while the rigid structure is connected to the box body 1 to ensure the stability of the pressure chamber.

[0120] In one embodiment, the top pressure chamber 61 is connected to the box body 1, and an adjustment chamber 67 is provided between the top pressure chamber 61 and the box body 1, a partition 68 is provided inside the adjustment chamber 67, and a plurality of through holes a25 are arranged on one side of the partition 68, and the movement of the partition 68 changes the number of the gas flow through holes a25 that the top pressure chamber 61 enters into the box body 1;

[0121] The partition 68 is suspended, and an electromagnetic ring 69 is provided at the bottom of the partition 68 to control the height of the partition 68;

[0122] The connecting structure 63 is a plug rod 631. The driving wheel 532 rotates to drive the plug rod 631 to move. The inner side of the plug rod 631 is provided with a plurality of connecting holes 632 for connecting the top pressure chamber 61 with the bottom pressure chamber 62.

[0123] The positioning frame 610, one end of the electromagnetic plate 64 can be swingably mounted on the inner side of the positioning frame 610, the insertion rod 631 is connected to the positioning frame 610, and the movement of the insertion rod 631 drives the positioning frame 610 to move;

[0124] The pressure pump 611 is fixed to the outside of the box body 1 and is used to increase the pressure inside the box body 1 to a fixed value.

[0125] In this embodiment, the positioning frame 610 is provided to control the movement of one end of the electromagnetic plate 64, and the electromagnetic block 65 pushes the other side of the electromagnetic plate 64 to swing. Therefore, in the process of the spray rod 3 swinging upward, the movement of the insertion rod 631 can be used to increase the pressure changes inside the top pressure chamber 61 and the bottom pressure chamber 62.

[0126] Among them, the states of the top pressure chamber 61 and the bottom pressure chamber 62 are connected through the connecting hole 632 on the inner side of the plug rod 631, which further increases the pressure inside the box body 1 and makes the top crown spraying process more stable.

[0127] Optionally, the driving structure 52 is a servo motor, which drives the transmission wheel 532 to rotate, so that the rotating wheel synchronously changes the positions of the slide rod 531 and the insertion rod 631, thereby adjusting the internal pressure of the top pressure chamber 61 and the bottom pressure chamber 62 and controlling the swing angle of the spray rod 3.

[0128] The present invention also provides a tree crown multi-operation mode spraying method, which is used for the above-mentioned sprayer and comprises the following steps:

[0129] Determine the spraying mode of the spraying rod 3 according to the state of the tree crown, and replace the spraying rod 3 corresponding to the state of the tree crown;

[0130] The pesticide is installed inside the thread groove 11, the top cone 12 penetrates into the pesticide bottle to destroy the seal of the pesticide bottle, and the metering unit 14 is used to measure the amount of pesticide;

[0131] The sprayer is moved by being transported or pushed by a vehicle, and the sprayer is controlled by a control terminal 7 to perform spraying operations;

[0132] The control end 7 controls the spraying rod 3 to swing toward the top of the tree canopy for spraying, and the connecting structure 5 drives the pressure balance component 6 to increase the pressure inside the box 1, so that the outlet pressure of the nozzle 4 increases;

[0133] During the spraying process, the spraying angle of the spraying rod 3 is continuously adjusted, and the pressure inside the box body 1 changes with the movement of the spraying rod 3 .

[0134] In one embodiment, during the spraying process, the liquid inside the box 1 decreases and the pressure becomes smaller, and the pressure change inside the box 1 is monitored, and the pressure stability inside the box 1 is maintained through the pressure balance component 6.

[0135] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0136] 1. During the crown spraying operation, the present invention can automatically adjust the internal pressure of the sprayer according to the adjustment of the spraying angle, thereby ensuring the pressure stability during the top crown spraying, realizing self-adjustment of the pressure at different spraying angles, and being able to adjust the telescopic state of the position of the nozzle 4.

[0137] 2. The present invention sets the spraying rod 3 for spraying medicine to an angle-adjustable state. When in use, the pressure balance component 6 is controlled by adjusting the angle of the spraying rod 3. When the angle of the spraying rod 3 is adjusted upward to spray the medicine upward, a greater pressure is obtained inside the sprayer, so that the liquid is sprayed out of the nozzle 4 at a greater pressure, and the operation effect on the top tree crown is better.

[0138] 3. The spray rod 3 is set to an adjustable state, and the spray rod 3 is set to two states, and both can form a stable and fast connection. When the spray rod 3 is in a straight rod state, the spraying state can be adjusted by rotating the spray rod 3. When the spray rod 3 is in an arc rod state, the spraying coverage range can be adjusted by extending the telescopic rod. Corresponding adjustments are made according to the different crown states of the required operations.

[0139] 4. In order to facilitate the control of the spray rod 3, a connecting structure 5 is set on the outer side of the spray rod 3 to realize the connection between multiple spray rods 3, and in the process of spraying, the control end 7 controls the angle of the spray rod 3. The control end 7 is independently set. When in use, the sprayer can be remotely controlled to adjust the spraying angle and pressure state of the sprayer.

[0140] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
