[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] An adjustable water volume farmland irrigation device includes an angle-adjustable mobile frame 1, a fixed frame 2, and a connecting pipe 3. The fixed frame 2 is fixedly connected to the upper end of the mobile frame 1. The connecting pipe 3 is rotatably connected to the inner side of the fixed frame 2 via a connecting shaft 8. A control frame 7 is welded and fixed to the upper and lower ends of one side of the fixed frame 2. A water outlet frame 4 is fixedly connected to one end of the connecting pipe 3. An adjustment mechanism 5 is rotatably connected to the inner side of the upper and lower ends of the water outlet frame 4 via a spring 9. A control mechanism 6 is installed at the upper and lower ends of the water outlet frame 4. The adjustment mechanism 5 includes an adjustment plate 51. A rotating shaft 52 is fixedly connected to the inner side of one end of the adjustment plate 51. A positioning groove 53 is opened in the middle of the end of the adjustment plate 51 away from the center point of the water outlet frame 4. The control mechanism 6 includes a control column 61. A ring plate 62 is fixedly connected to the middle of the control column 61. A telescopic spring 63 is provided on the outer side of the end of the control column 61 near the center point of the water outlet frame 4.

[0029] As a further implementation of this solution, the lower ends of the control frame 7 away from the fixed frame 2 are both raised, and the horizontal projection between the raised parts of the control frame 7 is an inverted triangle. With the above settings, the control column 61 can be moved during the rotation of the water outlet frame 4.

[0030] As a further implementation of this solution, both ends of the rotating shaft 52 are exposed on the outside of the water outlet frame 4. The exposed part of the rotating shaft 52 on the outside of the water outlet frame 4 is rotatably connected to the positioning ring 10 through the spring 9. The positioning ring 10 is fixedly connected to the water outlet frame 4. The spring 9 is set inside the positioning ring 10. With the above settings, the adjusting plate 51 can be automatically reset when idle.

[0031] As a further implementation of this scheme, the end of the regulating plate 51 near the connecting pipe 3 is arc-shaped, the rotating shaft 52 is rotatably connected to the water outlet frame 4, and there are two regulating mechanisms 5. Through the above settings, the stability of the regulating plate 51 during rotation can be improved.

[0032] As a further implementation of this solution, the end of the control column 61 near the center point of the water outlet frame 4 is slidably connected to the water outlet frame 4, and the end of the control column 61 near the center point of the water outlet frame 4 is tightly attached to the adjustment plate 51 through the positioning groove 53. Through the above settings, the control column 61 can be stably limited.

[0033] As a further implementation of this solution, the end of the control column 61 away from the center point of the water outlet frame 4 is positioned between the protrusions of the control frame 7. Both ends of the control column 61 are arc-shaped. Through the above arrangement, the stability of the control column 61 during movement can be further improved.

[0034] As a further implementation of this scheme, the horizontal projections of both the fixed frame 2 and the water outlet frame 4 are square, and the water outlet frame 4 is connected to the connecting pipe 3. Through the above settings, the stability during the irrigation process can be effectively improved.

[0035] Workflow: When using the adjustable-volume farmland irrigation device, the operator moves the entire device to the area requiring irrigation via the mobile frame 1. Then, it connects to the connecting pipe 3 via the water supply pipe. After connection, water is supplied through the water supply pipe for irrigation. During irrigation, controlling the rotation of the connecting pipe 3 rotates the water outlet frame 4 to the desired position. During irrigation, the mobile frame 1 continuously retracts. When the water outlet frame 4 faces directly forward of the irrigation area, the adjusting plate 51 does not reverse. At this point, the opening of the water outlet frame 4 is at its maximum, and the spray distance is shortest. When the water outlet frame 4 rotates, the control column 61 is controlled by the frame... The protrusions on both sides of the 7th section cause the control column 61 to move towards the water outlet frame 4. The greater the rotation angle, the greater the distance the control column 61 moves towards the water outlet frame 4. During the movement, the control column 61 will cause the adjusting plate 51 to flip. The greater the distance the control column 61 moves into the water outlet frame 4, the greater the angle of the adjustment plate 51 flipping. After the adjustment plate 51 flips, the opening of the water outlet frame 4 will become smaller, thereby adjusting the spraying distance. This setting can automatically increase the spraying distance when rotating the connecting pipe 3. During large-scale irrigation, it can automatically irrigate the outer farmland comprehensively, thereby improving the comprehensiveness of irrigation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
