[0026] See also Figure 1-5 As shown, an irrigation mechanism for forestry seedling cultivation includes a protection tube 1, the bottom end of the protection tube 1 is connected to a booster pump through a pipeline, the protection tube 1 is pre-buried in the soil, a slide groove is provided inside the protection tube 1, an adjustment component 2 is installed inside the protection tube 1, the adjustment component 2 includes a sliding ring 21, the sliding ring 21 is slidably installed inside the protection tube 1, a reciprocating screw 22 is threadedly connected inside the sliding ring 21, a circulation channel is provided inside the reciprocating screw 22, an irrigation component 3 is installed on the top of the reciprocating screw 22, and the irrigation component 3 includes a rotating cover 3 1, the rotating cover 31 is rotatably connected to the top of the reciprocating screw 22. When in use, the high-pressure water pushes the sliding ring 21 to slide upward, so that the irrigation component 3 rises and leaves the protection tube 1, and lifts up and opens the protection cover 4. The high-pressure water enters the interior of the rotating cover 31 through the circulation channel and is sprayed out from the water outlet 32 ​​to irrigate the forest seedlings. After the irrigation is completed, the sliding ring 21 slides downward under the gravity to store the irrigation component 3 in the protection tube 1, and the protection cover 4 is closed inside the protection tube 1 by torque to prevent the entry of soil, and effectively prevent the water outlet 32 ​​from being blocked by mud.

[0027] The top end of the protection tube 1 is hinged with a protection cover 4 via a torsion spring shaft.

[0028] The bottom end of the reciprocating screw 22 is fixedly connected with a rotating tube 23 .

[0029] The outer wall of the rotating tube 23 is annular and fixedly connected with a plurality of blades 24. The high-pressure water flow cooperates with the blades 24 to push the reciprocating screw 22 to rotate, so that the irrigation component 3 moves up and down, and then the irrigation range is cyclically adjusted. Compared with the existing technology, the irrigation range of the forest seedlings is increased.

[0030] A plurality of water outlet holes 32 are formed on the side wall of the rotating cover 31 .

[0031] The top of the rotating cover 31 is rotatably connected to a rotating column 33 , and the lower side wall of the rotating column 33 is fixedly connected to a plurality of blades 34 distributed in an annular shape.

[0032] A slot 35 is defined on the upper side wall of the rotating column 33 .

[0033] A threaded connection seat 36 is fixedly connected to the top of the rotating cover 31, and a threaded connection port is provided on the surface of the threaded connection seat 36. The inner thread of the threaded connection port is connected to a limit pin 37. The limit pin 37 is rotated and inserted into the interior of the card slot 35 to connect the rotating column 33 with the rotating cover 31. The rotating cover 31 is driven to rotate by the cooperation of high-pressure water and blade 2 34, and then the water outlet hole 32 is rotated for irrigation to avoid the occurrence of irrigation dead angles. By pulling out the limit pin 37 and canceling the connection between the rotating column 33 and the rotating cover 31, the water outlet hole 32 can maintain a relatively stable spraying angle, and the user can flexibly adjust it according to usage requirements.

[0034] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art.

[0035] Working principle: when in use, high-pressure water pushes the sliding ring 21 to slide upward, so that the irrigation component 3 rises and leaves the protective tube 1, and lifts up and opens the protective cover 4. The high-pressure water enters the interior of the rotating cover 31 through the circulation channel, and is sprayed out from the water outlet 32 ​​to irrigate the seedlings. Through the cooperation of the high-pressure water flow and the blade 24, the reciprocating screw 22 is pushed to rotate, so that the irrigation component 3 moves up and down, and then the irrigation range is cyclically adjusted to increase the irrigation range of the seedlings.

[0036] The limit pin 37 is rotated and inserted into the slot 35, and the rotating column 33 is connected to the rotating cover 31. The high-pressure water and the blade 2 34 drive the rotating cover 31 to rotate, and then the water outlet 32 ​​is rotated for irrigation to avoid the occurrence of irrigation dead angles. By pulling out the limit pin 37 and canceling the connection between the rotating column 33 and the rotating cover 31, the water outlet 32 ​​can maintain a relatively stable spraying angle, and the user can flexibly adjust it according to usage requirements.

[0037] After irrigation is completed, the sliding ring 21 slides downward under gravity to store the irrigation assembly 3 inside the protection tube 1, and the protection cover 4 is closed inside the protection tube 1 by torque to prevent soil from entering, effectively preventing the water outlet 32 ​​from being blocked by mud.
