[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example 1, such as Figures 1 to 4 As shown, this utility model is an intelligent spraying device, including a hydroponic trough 4 arranged in the front-to-back direction, a gantry frame 9 on the upper outer side of the hydroponic trough 4, an automatic walking mechanism at the bottom of the gantry frame 9 to drive its front-to-back movement, a medicine storage tank 16 arranged in the left-to-right direction fixed on the top of the gantry frame 9, a liquid addition hopper 15 fixed at one end of the top of the medicine storage tank 16, the bottom of the medicine storage tank 16 being inclined with the outside higher than the inside, a liquid extraction pipe fixed at the lowest point in the middle of the medicine storage tank 16, a liquid pump 14 fixed on the gantry frame 9 connected to the liquid pump 14, an outlet pipe connected to the outlet of the liquid pump 14, a spray pipe 17 connected to the other end of the outlet pipe, the spray pipe 17 being horizontally installed at the bottom of the gantry frame 9, and multiple nozzles 18 fixed at the bottom of the spray pipe 17 in the left-to-right direction.

[0021] During operation, the automatic walking mechanism moves the gantry 9 to one end of the hydroponic tank 4, and then adds the prepared medicine solution from the liquid filling hopper 15 into the medicine storage tank 16. Since the medicine storage tank 16 is arranged in a long strip along the left and right direction, the height of the medicine storage tank 16 can be greatly reduced, the overall center of gravity can be lowered, and the movement can be more stable. Then the liquid pump 14 starts, draws the medicine solution in the medicine storage tank 16 and sends it into the spray pipe 17 and then sprays it out from the nozzle 18. At this time, the automatic walking mechanism carries the gantry 9 and the spray pipe 17, nozzle 18 and medicine storage tank 16 on it to move to the other end of the hydroponic tank 4, so as to spray the medicine solution evenly. When it reaches the other end of the hydroponic tank 4, it stops moving and the liquid pump 14 is turned off.

[0022] Example 2, based on Example 1, includes a corrugated pipe 12 on the outlet pipe, and support plates 11 fixed to both ends of the spray pipe 17. The support plates 11 have vertical mounting holes, and adjusting screws 10 are installed within these holes. The top of the adjusting screws 10 is fixed to the gantry frame 9. Adjusting nuts 13 are installed on the adjusting screws 10 above and below the support plates 11. Before operation, the height of the spray pipe 17 and the nozzle 18 can be adjusted by rotating the adjusting nuts 13 on the adjusting screws 10 according to the height of the plants in the hydroponic trough 4.

[0023] The top of the pesticide storage tank 16 is equipped with a removable cover plate 19, and the liquid addition hopper 15 is fixed on the cover plate 19. The cover plate 19 has downward-bent limiting flanges around its perimeter. When it is necessary to replace the pesticide or when the pesticide storage tank 16 is blocked, the cover plate 19 can be opened to clean the inner wall of the pesticide storage tank 16 or to unclog the outlet at the bottom of the pesticide storage tank 16.

[0024] The automatic walking mechanism includes guide rails 6 arranged along the front-to-back direction on the left and right sides of the lower part of the hydroponic tank 4. A mounting base plate 8 is located above the guide rails 6, and at least two movable wheels 7 are arranged along the front-to-back direction on the mounting base plate 8. One end of each movable wheel 7 is connected to a drive motor 5, which is fixed to the mounting base plate 8. The drive motor 5 is a servo motor. The rotation of the drive motor 5 drives the movable wheel 7 to rotate, thereby driving the movable wheel 7 to roll along the guide rails 6, thus causing the mounting base plate 8 to move back and forth.

[0025] A support plate 1 is fixed to the bottom of the guide rail 6, and the support plate 1 is fixed to the outer wall of the hydroponic tank 4.

[0026] A guide sleeve 3 is fixed on the inner wall of the mounting base plate 8. A guide rod 2 is provided inside the guide sleeve 3. The guide rod 2 is parallel to the guide rail 6. Support rods 20 are fixed at the front and rear ends of the guide rod 2. The support rods 20 are fixed on the outer wall of the hydroponic tank 4.

[0027] A fixing seat 21 is fixed to the outer side of the guide sleeve 3, and the fixing seat 21 is fixed to the side wall of the mounting base plate 8 by bolts. Position sensors are fixed to both the front and rear ends of the guide rail 6. The position sensors are connected to a PLC controller, which in turn connects to the drive motor 5 and the liquid pump 14. When the moving wheel 7 moves to the position of the position sensor at both ends, it sends a signal to the PLC controller to stop the drive motor 5. A liquid level sensor is installed at the bottom center of the medicine storage tank 16. The liquid level sensor is connected to the PLC controller, which in turn connects to an alarm. The liquid level sensor can detect the lowest liquid level in the medicine storage tank 16. When the lowest liquid level is reached, it sends a signal to the PLC controller to activate the alarm and remind the user to replenish the medicine, making it more intelligent.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
