The spraying barrel 10 is internally provided with a liquid cavity for storing pesticides or water fertilizers. The moving frame 11 is fixedly connected to both sides of the spraying barrel 10. The moving wheel 12 is arranged on the moving frame 11. The moving motor 13 is arranged on one of the moving frames 11 and is used to drive the moving wheel 12 to move along the connecting rod 9. The connecting rod 9 is made of aluminum alloy. Magnets are arranged on the contact surfaces of the connecting rod 9 and the moving wheel 12. The inner ring of the moving wheel 12 is made of steel.

The height adjusting push rod 17 is symmetrically arranged on both sides of the driving frame 6. The symmetrically arranged height adjusting push rods 17 control the hydraulic flow of the two push rods through a hydraulic pump, so as to ensure that the height adjusting push rods 17 on both sides obtain the same oil pressure and realize synchronous movement. The telescopic ends of the height adjusting push rod 17 are hingedly connected with two connecting rods 9. The ends of the connecting rods 9 away from the height adjusting push rod 17 are movably inserted into the connecting sleeve 18. The connecting sleeve 18 is rotationally connected to the driven frame 8.

[0045] The detection mechanism comprises a distance sensor 19. The distance sensor 19 is a reflective infrared sensor. The distance sensor 19 is fixedly connected to the connecting sleeve 18 and can move with the connecting sleeve 18. Therefore, the distance sensor 19 can still detect the position of the spraying barrel 10 after the connecting rod 9 moves. The distance sensor 19 is used to detect the position of the spraying barrel 10. The distance sensor 19 can collect the position of the moving frame 11 on the connecting rod 9 in real time. Since the moving frame 11 and the spraying barrel 10 are fixedly connected, the position of the moving frame 11 can reflect the position of the spraying barrel 10. The release mechanism comprises an electromagnetic opening valve 102. The electromagnetic opening valve 102 is opened and closed by electricity. When the distance sensor 19 detects that the electromagnetic opening valve 102 is above the liquid cavity, the electromagnetic opening valve 102 is opened so as to input the water fertilizers into the liquid cavity.

[0046] The height synchronization mechanism includes a synchronization rod 20, with both ends of the synchronization rod 20 fixedly connected to the moving end of the height adjustment push rod 17 and the telescopic tube 3, respectively. Therefore, when the height adjustment push rod 17 moves, the telescopic tube 3 will move synchronously.

[0047] The docking opening mechanism includes docking opening valve one 21, docking opening valve two 22, sealing motor 23, and sealing sleeve 24. Docking opening valve one 21 is located at the pesticide outlet, and docking opening valve two 22 is located at the bottom of the telescopic tube 3. Both docking opening valve one 21 and docking opening valve two 22 are solenoid valves. Docking opening valve one 21 and docking opening valve two 22 will only open after the sealing motor 23 drives the sealing sleeve 24 to rotate at a specified angle. Similarly, when the sealing motor 23 drives the sealing sleeve 24 to flip, docking opening valve one 21 and docking opening valve two 22 will directly close. The sealing sleeve 24 is connected to the liquid inlet end of the telescopic tube 3. The sealing motor 23 is a servo motor that can precisely control its rotation. The sealing motor 23 is used to drive the sealing sleeve 24 to rotate. By rotating the sealing sleeve 24, the moving end of the sealing sleeve 24 is connected to or disconnected from docking opening valve one 21.

[0048] The docking output mechanism includes a three-way connector 25, a telescopic rod 26, an output valve 27, and a position sensor 28. The three-way connector 25 is located at the liquid outlet end of the telescopic tube 3. Both outlets of the three-way connector 25 are connected to the telescopic rod 26. One end of the telescopic rod 26 is connected to the output valve 27. A position sensor 28 is installed at the pesticide inlet of the liquid chamber. The position sensor 28 is a reflective infrared sensor. When the position sensor 28 detects that the output valve 27 is inserted into the liquid chamber, the output valve 27 will open.

[0049] Working principle: When in use, the drive motor 7 first drives the drive frame 6 to move, and the connecting rod 9 drives the driven frames 8 on both sides to move. When it moves to the side of the fruit tree, the sealing motor 23 drives the sealing sleeve 24 to rotate at a specified angle, thereby connecting the docking opening valve 1 21 and docking opening valve 22 to each other. Then the docking opening valve 1 21 and docking opening valve 22 open to connect the telescopic pipe 3 and the pesticide delivery pipe 2. Before moving, the sealing motor 23 drives the sealing sleeve 24 to reverse and close the docking opening valve 1 21 and docking opening valve 22.

[0050] When applying fertilizer, please refer to the instructions provided. Figure 3 As shown, the electromagnetic valves 102 on both sides are opened to input water and fertilizer into the liquid chamber. After the electromagnetic valves 102 are closed, the motor 13 drives the spray cylinder 10 to move along the connecting rod 9 and spray water and fertilizer through the nozzle 14.

[0051] When the distance sensor 19 detects that the motion frame 11 has moved the spray cylinder 10 to the other side of the connecting rod 9 (as per the instruction manual), Figure 1When the position sensor 28 detects that the output valve 27 is inserted into the liquid cavity, the output valve 27 is opened, the pesticide is input into the spraying cylinder 10, and the pesticide is sprayed through the spray head 14 when the spraying cylinder 10 is driven to return by the movement motor 13;

[0052] With the growth of the fruit trees, the height of the connecting rod 9 is adjusted by the height adjustment push rod 17 so as to adjust the spraying position according to the crown height of the fruit trees at different stages;

[0053] When cleaning is needed, the spraying cylinder 10 is removed in the stopped state for cleaning, which is convenient and fast.

[0054] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
