DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1-4 As shown, a technical solution provided by the utility model:

[0026] A spraying device for ecological gardening that is easy to spray, comprising a spraying barrel 1, a mounting frame 16 is arranged on all four sides of the outer wall of the bottom end of the spraying barrel 1, a mounting hole 17 is penetrated and arranged in the middle of the mounting frame 16, a barrel groove 2 is opened inside the spraying barrel 1, a straight pipe 3 is movably arranged inside the barrel groove 2, and a piston 4 movably connected to the barrel groove 2 is arranged at the bottom end of the straight pipe 3; a spraying mechanism is arranged at the upper end of the straight pipe 3, and the spraying mechanism includes a barrel cover 5, and the barrel cover 5 is fixedly installed on the top end of the straight pipe 3, and an annular nozzle 6 is arranged in an annular manner below the straight pipe 3 near the barrel cover 5, and the annular nozzle 6 is connected to the inside of the straight pipe 3, and a water inlet nozzle 13 is arranged at the upper end of the straight pipe 3 near the piston 4, and the water inlet nozzle 13 is connected to the inside of the straight pipe 3;

[0027] In this embodiment, during spraying, the medicine liquid is pumped into the water inlet tank 9 by an external compression pump through a water supply pipeline. At this time, the medicine liquid controls the piston 4 to float, and the piston 4 drives the straight pipe 3 to rise when it floats. After the straight pipe 3 is lifted, the annular nozzle 6 is exposed from the outside of the upper end of the spray barrel 1 until the water inlet nozzle 13 is connected with the water outlet 11. At this time, the medicine liquid enters the flow channel 10 from the water inlet 12 and enters the water inlet nozzle 13 from the water outlet 11, and then the medicine liquid is sprayed from the annular nozzle 6 to maintain the surrounding plants, thereby achieving the purpose of facilitating spraying.

[0028] like Figure 2 and Figure 4As shown, an opening and closing mechanism is arranged between the spray barrel 1 and the bottom end of the straight pipe 3, and the opening and closing mechanism includes a water inlet groove 9, which is arranged in the middle of the bottom end of the spray barrel 1, and the water inlet groove 9 is connected with the barrel groove 2. The four sides of the spray barrel 1 are provided with flow channels 10, and the flow channel 10 is located in the middle of the barrel groove 2 and is connected with a water outlet 11, and the flow channel 10 is located at the bottom of the barrel groove 2 and has a water inlet 12, and guide blocks 14 are symmetrically arranged on the outer walls on both sides of the middle part of the straight pipe 3, and wall grooves 15 are opened inwardly on both sides of the upper end of the barrel groove 2, and the wall grooves 15 are slidably connected with the guide blocks 14, and the guide blocks 14 are connected to the upper ends of the wall grooves 15 through springs;

[0029] In this embodiment, when the external compression pump is turned off, the supply of liquid medicine stops. At this time, the compressed spring at the upper end of the guide block 14 will rebound to control the guide block 14 to descend along the wall groove 15. When the guide block 14 descends, it drives the straight pipe 3 to descend synchronously. When the straight pipe 3 descends, it drives the annular nozzle 6 to retract into the barrel groove 2. This can prevent the annular nozzle 6 from being exposed to the outside for a long time and causing blockage.

[0030] like Figure 2 As shown, a sealing groove 7 is provided in an annular manner on the upper end surface of the spray barrel 1, and a sealing ring 8 matching the sealing groove 7 is provided in an annular manner on the outer side of the bottom end of the barrel cover 5;

[0031] In this embodiment, when the straight pipe 3 descends, it drives the annular nozzle 6 to retract into the barrel groove 2 until the sealing ring 8 at the lower end of the barrel cover 5 seals the sealing groove 7 at the upper end of the spray barrel 1, thereby achieving the purpose of sealing.

[0032] Working principle: The lower end of the device is buried in a pre-buried groove on the ground and connected to a preset water supply pipeline. Then, bolts are used to fix the mounting frame 16 on the outside of the spray barrel 1 to the ground. During spraying, the liquid medicine is pumped to the water inlet tank 9 by an external compression pump through the water supply pipeline. At this time, the liquid medicine controls the piston 4 to float. When the piston 4 floats, it drives the straight pipe 3 to rise. After the straight pipe 3 rises, the annular nozzle 6 is exposed from the outside of the upper end of the spray barrel 1 until the water inlet nozzle 13 is connected to the water outlet 11. At this time, the liquid medicine flows from the water inlet 12 enters the flow channel 10, and enters the water inlet 13 from the water outlet 11, and then sprays the liquid medicine from the annular nozzle 6 to maintain the surrounding plants; when the external compression pump is turned off, the liquid medicine stops being supplied, and at this time the compressed spring at the upper end of the guide block 14 will rebound to control the guide block 14 to descend along the wall groove 15, and when the guide block 14 descends, it drives the straight pipe 3 to descend synchronously, and when the straight pipe 3 descends, it drives the annular nozzle 6 to be retracted into the barrel groove 2, until the sealing ring 8 at the lower end of the barrel cover 5 seals the sealing groove 7 at the upper end of the spray barrel 1.
