Description

Technical Field

[0001] This utility model relates to the field of fertilization and irrigation technology, specifically to an agricultural irrigation device capable of precise irrigation. Background Technology

[0002] Agricultural irrigation mainly refers to irrigation operations carried out in agricultural cultivated areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation, and micro-irrigation. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, due to insufficient rainfall or uneven distribution, the water requirements of crops are often not met. Therefore, artificial irrigation is necessary to supplement the lack of natural rainfall. Fertilization refers to agricultural technical measures that apply fertilizer to the soil or spray it on plants to provide the nutrients needed by plants and maintain and improve soil fertility. During irrigation, fertilizer can be mixed with water and applied through irrigation.

[0003] Publication No. CN222283964U discloses an agricultural water and fertilizer irrigation device. It comprises an electric telescopic rod, a protective box, a drive rod, a transmission rod, a storage box, and a nozzle. The water pump output discharges water and fertilizer through a water outlet pipe. During operation, the connecting hose of the storage box can be stretched and adjusted. The nozzle on the surface of the storage box sprays water and fertilizer. The drive rod rotates the electric telescopic rod connected to the inner wall of the connecting clamp to adjust its angle. Controlling the electric telescopic rod adjusts the height of the fixed clamp at the top, and the connecting block adjusts the angle of the top storage box, thereby adjusting the nozzle angle. This achieves the effect of controlling the nozzle angle and height, and facilitates control over the sprayed water and fertilizer area. However, this patent still has the following problems in actual use:

[0004] Although this agricultural water and fertilizer irrigation device can adjust the height and angle of the nozzles using an electric telescopic rod, protective box, drive rod, transmission rod, storage box, and nozzle configuration, it is not suitable for precise irrigation and fertilization of densely planted crops. Due to the special characteristics of crops, some crops grow densely while others grow sparsely. For densely planted crops, even by adjusting the angle and height of the nozzles, it is impossible to extend the nozzles close to the crops to reduce the distance between the crops and the nozzles, thus failing to achieve the effect of precise irrigation. This results in fertilizer waste and affects the efficiency of crop irrigation and fertilization.

[0005] Therefore, a precision irrigation device for agriculture is proposed to address the problems mentioned above. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This agricultural irrigation device for precise irrigation utilizes a rotating motor to drive a rotating worm gear.

[0020] 1. By setting up a fertilization and irrigation mechanism, a rotating motor can drive a rotating worm gear to rotate.

The translation motor is started to drive the translation threaded rod to rotate, which causes the translation threaded sleeve to move the negative pressure regulating device and the irrigation nozzles. The mixture of irrigation water and fertilizer is pumped out using the connecting pipe and the sprinkler pump, thus achieving uniform irrigation and fertilization of the crops.

[0021] 2. By setting up a mixing mechanism, irrigation water and fertilizer can be put into the mixing cylinder through the feeding hopper. Starting the mixing motor drives the mixing main gear to rotate. Utilizing the meshing connection between the mixing main gear, mixing driven gear, and meshing gear ring, the mixing rotating disc drives the mixing auger to revolve. At the same time, the mixing driven gear drives the mixing auger to rotate on its own axis, which can achieve uniform mixing of fertilizer. Starting the lifting motor drives the sprocket transmission assembly and the lifting bidirectional threaded rod to rotate, which causes the lifting threaded sleeve to drive the lifting rotating rod to rotate. At the same time, the lifting sliding sleeve slides on the outside of the lifting sliding rod, thereby realizing the adjustment of the distance between the lifting base frame and the lifting top frame. The height of the fertilization and irrigation mechanism can be adjusted. The moving wheels realize the movement of the fertilization and irrigation vehicle, thereby realizing uninterrupted fertilization and irrigation. Attached Figure Description

[0033] Working principle: Before using this precision irrigation device, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6 As shown, firstly, when irrigating and fertilizing densely planted crops, the rotating motor 104 drives the rotating worm 105 to rotate.

Simultaneously, the mixing driven gear 206 drives the mixing auger 209 to rotate, achieving uniform mixing of fertilizer. Finally, the lifting motor 215 is started, driving the sprocket transmission assembly 216 and the lifting bidirectional threaded rod 217 to rotate. This causes the lifting threaded sleeve 218 to drive the lifting rotating rod 219 to rotate. At the same time, the lifting sliding sleeve 220 slides on the outside of the lifting sliding rod 221, thereby adjusting the distance between the lifting base frame 222 and the lifting top frame 213.
