DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those ordinarily skilled in the art without creative work fall within the scope of protection of the utility model.

[0023] All other embodiments obtained by those ordinarily skilled in the art without creative work fall within the scope of protection of the utility model.

[0024] Please refer toFigures 1-5 The utility model discloses a movable water spraying device for greenhouse planting, which comprises a bottom plate 2 and a water spraying mechanism located on the bottom plate 2.

[0025] The top wall of the vertical pipe 8 is provided with a shell 12, and the movable rod 11 moves in the shell 12. A spring 13 is installed in the shell 12, one end of the spring 13 is connected to a limiting block 14, the limiting block 14 protrudes from the shell 12, a plurality of limiting grooves 15 are formed in the movable rod 11, and the limiting block 14 is matched with the limiting grooves 15. The limiting block 14 clamps the movable rod 11 through the limiting grooves 15, preventing the movable rod 11 from moving upward, and ensuring the stability of the movable rod 11 during the water spraying process.

[0026] The lower surface of the limiting groove 15 is a right-angle structure, and the upper surface is an arc structure. The arc structure facilitates the downward movement of the movable rod 11, and the right-angle structure prevents the upward movement of the movable rod 11, ensuring the stability of the movable rod 11. When the movable rod 11 needs to move upward, the limiting block 14 can be pushed away from the limiting groove 15.

[0027] The outer surface of the piston 16 is wrapped with a rubber sealing ring 5, which makes the piston 16 have better sealing performance.

[0028] The movable rod 11 is a telescopic rod, which prevents the movable rod 11 from being too long.

[0029] The water spraying mechanism comprises a water tank 4 installed on the bottom plate 2. The water tank 4 is provided with a water pump 6. The water outlet of the water pump 6 is provided with a first water pipe 7. One end of the first water pipe 7 is communicated with the vertical pipe 8. A plurality of second water pipes 9 are installed on the vertical pipe 8. Each second water pipe 9 is provided with a plurality of spray heads 10. The water pump 6 sprays the water in the water tank 4 through the first water pipe 7, the vertical pipe 8, the second water pipes 9 and the spray heads 10, which is used for irrigating crops in the greenhouse.

[0030] A push handle 1 is installed on the bottom plate 2, and universal wheels 3 are installed at the bottom end of the bottom plate 2. The push handle 1 and the universal wheels 3 can make the water spraying device move flexibly in the greenhouse and reach different areas for irrigation.

[0031] The working principle of the utility model is as follows: when the device works, the water pump 6 is started. The water pump 6 sprays the water in the water tank 4 through the first water pipe 7, the vertical pipe 8 and the second water pipes 9, and then through the spray heads 10, which is used for irrigating crops in the greenhouse.

[0032] When the height of the crops is low, the movable rod 11 is pushed down, and the movable rod 11 drives the piston 16 to move downward in the stand pipe 8, the water level in the stand pipe 8 is lowered, and the height of the water spraying is lowered;

[0033] When the height of the crops is high, the movable rod 11 is pulled up, and the piston 16 moves upward in the stand pipe 8 following the movable rod 11, the water level in the stand pipe 8 is raised, and the height of the water spraying is raised;

[0034] In order to make the movable rod 11 more stable during the water spraying, when the movable rod 11 is adjusted to the proper position, the limiting block 14 clamps the column limiting groove 15, thereby fixing the movable rod 11, so that the movable rod 11 cannot move upward under the water impact, and the stability of the water spraying height is ensured.

[0035] The above has carried on the detailed description to one embodiment of the utility model, but the content described can be considered as used for limiting the implementation scope of the utility model, and cannot be considered as used for limiting the implementation scope of the utility model. Any equivalent change and improvement within the application scope of the utility model should still belong to the patent coverage scope of the utility model.
