[0027] The specific implementation methods, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] Reference Figure 1-Figure 4 The utility model discloses a fertilizing device for rice planting, comprising a fertilizing pipe 14 preset in a rice field, wherein a water inlet pipe 3 and a liquid inlet pipe 4 are connected at one end of the fertilizing pipe 14, water is fed into the water inlet pipe 3, and fertilizing liquid is fed into the liquid inlet pipe 4, the fertilizing pipe 14 comprises an outer pipe 2 and an inner pipe 1, a bearing 5 is arranged between the outer pipe 2 and the inner pipe 1, a through hole is arranged on the outer wall below the outer pipe 2, and a through hole is arranged on the side wall of the inner pipe 1, and the two through holes can be aligned by rotating the inner pipe 1, and after the alignment, the liquid in the inner pipe 1 will be sprayed onto the farmland in the form of spray irrigation, and the through hole of the outer pipe 2 is arranged obliquely, and the inner pipe 1 is provided with a bearing 5 between the outer pipe 2 and the inner pipe 1. When the pressure is sufficient, oblique sprinkler irrigation can be achieved, which is more precise. When the pressure in the inner pipe 1 is reduced, drip irrigation can be achieved. Drip irrigation is generally used for daily irrigation, and sprinkler irrigation is used for fertilization. One end of the inner pipe 1 has an extension section 6, and the end of the extension section 6 is connected and linked to the motor through a right-angle transmission mechanism. A stirring device 7 is also provided in the inner pipe near the end of the extension section 6. The stirring device 7 is a high-speed fan blade and a main shaft 9, and a stirring motor 8 that drives the main shaft 9. When the water inlet pipe 3 and the liquid inlet pipe 4 are simultaneously fed with liquid, the stirring device 7 achieves better uniform stirring, and the preferred stirring main shaft 9 and blades are auger shafts and shaft blades.

[0029] The length of the fertilizer pipe 14 is 8-10 meters, and a transfer joint is required every 8-10 meters, including a pipe connector 16, the pipe connector 16 includes an outer pipe 2 connector and an inner pipe 1 connector, and the pipe connector 16 is at least a two-way pipe connector. The outer edge of the inner pipe 1 connector is provided with a bearing connector 12, and the bearing connector 12 is used to achieve the purpose of non-linkage connection with the inner pipe 1.

[0030] When the length of the fertilization pipe 14 is less than 6 meters, it is not necessary to add fertilizer at both ends, so the other end of the fertilization pipe 14 is connected to the water inlet pipe 3 to achieve irrigation.

[0031] When the length of the fertilization pipe 14 exceeds 8 meters, the stirring effect of the stirring device 7 is poor, so it is necessary to further include a second stirring device 10 in the pipe connector 16. The second stirring device 10 is a double-head fan to increase the stirring efficiency and achieve more uniform mixing of water and fertilizer.

[0032] When implementing the utility model, it is necessary to have a certain distance between the fertilization pipe 14 and the ground to facilitate the implementation of sprinkler irrigation. Therefore, a support frame 11 is required to be provided at the bottom of the fertilization pipe 14 and the pipe connector 16. In addition to playing a supporting role, the support frame 11 can also play a role in adjusting the distance.

[0033] Reference Figure 5 When the utility model realizes fertilization, it is necessary to introduce liquid fertilizer into the liquid inlet pipe 4, and then add water to the water inlet pipe 3 in proportion. After both are added, the stirring device 7 is started to stir the liquid in the pipe evenly for about 20-30 minutes, and then the control motor of the extension section 6 is started. The motor is a servo motor, and the number of revolutions of the motor is preset and adjusted. At this time, the inner pipe 1 will rotate so that the through hole of the inner pipe 1 and the through hole area of ​​the outer pipe 2 intersect by 10%. At this time, water or air pressure is added to the water inlet pipe 3 to drive the liquid in the inner pipe 1 to spray outward to realize the sprinkler irrigation and fertilization of the rice root. When fertilization is not needed, the through holes of the inner and outer pipes 2 are disconnected again. After the inner pipe 1 is filled with water, the through hole areas overlap by 50-100%. At this time, the water flow rate is low, and irrigation can be realized. If drip irrigation is needed, the water inlet rate can be adjusted at this time.
