[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a spraying machine for Chinese medicinal herb cultivation, including a water tank 1. A fixed frame 2 is installed on the inner top wall of the water tank 1, and a water pump 3 is installed inside the fixed frame 2. Fixed seats 4 are symmetrically connected to both sides of the top of the water tank 1. Fixed shafts 5 are rotatably connected between the two sets of fixed seats 4 on the same side. Two sets of connecting seats 6 are fixedly installed on the outer side of the two sets of fixed shafts 5. A hollow plate 7 is installed between the two sets of connecting seats 6 on the same side. Multiple sets of square tubes 8 are connected to one side of the hollow plate 7. Square tubes 9 are slidably connected inside the square tubes 8. Multiple sets of nozzles 19 are installed on one side of the second tube 9, and a fixing plate 10 is connected to one side of each set of the second tubes 9 on the same side; a sliding plate 11 is installed on one side of each second tube 9, and a guide frame 12 corresponding to the sliding plate 11 is installed on one side of each first tube 8, and the sliding plate 11 is slidably connected inside the guide frame 12; multiple sets of hemispherical grooves are opened on both inner side walls of the guide frame 12, and placement grooves are opened on both sides of the sliding plate 11, and spring pins 13 are installed inside the placement grooves, and the ball head of the spring pin 13 abuts against the inner arc surface of any of the hemispherical grooves.

[0026] In this configuration, one side of each of the two sets of connecting seats 6 is vertically mounted with a side plate 14. Each side plate 14 has a through hole at its center, and one end of each fixed shaft 5 is rotatably connected to the through hole. A pawl 15 is connected to one side of each side plate 14, and a spring connects the pawl 15 to the side plate to ensure stable engagement between the pawl 15 and the ratchet 16. One end of each of the two sets of fixed shafts 5 is connected to a corresponding ratchet 16, and the pawl 15 engages with the ratchet 16. A handwheel 17 is fixedly mounted on the end of each fixed shaft 5 near the pawl 15, allowing the fixed shaft 5 to be adjusted to the desired angle by rotating the handwheel 17. Simultaneously, the ratchet 16 and pawl 15 work together to fix the fixed shaft 5, ensuring angle stability during spraying.

[0027] The square tube 8 has an installation groove on the side near the fixing plate 10, and a sealing ring 18 is installed inside the installation groove. The sealing ring 18 can effectively prevent the medicine from leaking at the sliding interface and reduce the waste of medicine.

[0028] The square tube 8 and the square tube 9 each have multiple sets of through holes on one side of their interior. The square tube 8 and the square tube 9 each have threaded holes on one side of the through holes. One end of the nozzle 19 is located inside the through hole, and the other end of the nozzle 19 is threaded into the threaded hole. This allows the threaded nozzle 19 to be quickly replaced to meet the needs of different types of agents (such as atomization and drip irrigation). At the same time, the nozzle 19 is installed in an embedded manner to ensure that the square tube 9 will not interfere with its movement when it is extended or retracted.

[0029] The water tank 1 has a through groove on one side that is connected to the fixed frame 2. An inspection door 20 is hinged inside the through groove. The inspection door 20 provides direct access to the water pump 3, reducing downtime, improving equipment utilization, and enhancing the convenience of water pump 3 maintenance.

[0030] The water pump 3 has an inlet pipe 21 at its inlet end, with one end of the inlet pipe 21 passing through the fixed frame 2 and extending to the inner bottom surface of the water tank 1. The top of the water tank 1 has a through hole, and an outlet pipe 22 is connected to the outside of the through hole. The bottom end of the outlet pipe 22 extends into the fixed frame 2 and is fixedly connected to the outlet end of the water pump 3. Valves 23 are installed on both sides of the outlet pipe 22, and one side of each of the two sets of valves 23 is connected to a telescopic hose 24. One end of each telescopic hose 24 is connected to a corresponding hollow plate 7. The cooperation of the valves 23 and the telescopic hose 24 enables independent control on both sides, allowing for differentiated application of pesticides to different areas and saving pesticides.

[0031] The water tank 1 is equipped with casters 25 at the four corners of its bottom end, and a handle 26 is installed on one side of the water tank 1. The casters 25 and the handle 26 are combined to facilitate movement in narrow fields and reduce labor intensity.

[0032] The working principle of this embodiment:

[0033] When using the sprayer, first move the device to the area to be sprayed using the casters 25 at its bottom; then turn the handwheel 17 to drive the fixed shaft 5 to rotate, which in turn drives the hollow plate 7, square tube 8, and square tube 9 to rotate as a whole through the connecting seat 6. When the rotation reaches the appropriate angle, stop rotating, and the fixed shaft 5 can be fixed by the engagement of the ratchet 16 and the pawl 15; then grasp the fixed plate 10 and pull the square tube 9 out of the inside of the square tube 8 to the appropriate length, and then use the spring pins on both sides of the sliding plate 11. With the cooperation of multiple sets of hemispherical grooves on both sides of the guide frame 12 and 13, the square tube 2 9 is fixed; then the water pump 3 is started, and the water pump 3 draws the medicine inside the water tank 1 through the water inlet pipe 21. At the same time, the valve 23 to be used is opened, so that the medicine is diverted through the water outlet pipe 22 to the telescopic hoses 24 on both sides. The valve 23 can control the flow on both sides to achieve single-sided or double-sided spraying; the medicine inside the telescopic hose 24 is sequentially transported to the hollow plate 7, square tube 1 8 and square tube 2 9, and sprayed out by the nozzle 19 on one side of square tube 1 8 and square tube 2 9.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
