Description

Technical Field

[0001] The present invention relates to the technical field of agricultural fertilization, and in particular to a smart agricultural water-saving irrigation and fertilization device. Background Art

[0002] Smart agriculture is a new concept in which technology is applied to agricultural planting. During the entire agricultural planting process, there is no need for real-time manual supervision and fertilization and irrigation. Only regular inspections are required. Equipment is used to uniformly fertilize and irrigate crops and evenly input fertilizer and water to the roots of crops. The water resource utilization rate is high and it saves time and effort. However, when the leaves of plants need to be sprayed with water for cooling or fertilization, drip irrigation will not work and can only be done manually. The labor intensity of the staff is high. Patent documents have been issued to improve this.

[0003] For example, Chinese patent CN113841601A, a smart agricultural intelligent water-saving irrigation system, includes a water tank, a plurality of fertilizer storage tanks are arranged above the water tank, the lower end of each fertilizer storage tank is connected to a feed pipe, each feed pipe is rotatably connected with a spiral feed rod, the lower end of the water tank is connected to a water outlet pipe, and a second solenoid valve is arranged on the water outlet pipe; the free end of the water outlet pipe is connected to a plurality of irrigation pipes, each irrigation pipe is connected to a plurality of branch pipes, the free end of each branch pipe is connected to a permeation cannula, and the upper end of each irrigation pipe is upwardly provided with a water outlet connection pipe; the side of each irrigation pipe is provided with a sliding track, each sliding track is provided with an automatic sliding automatic sprinkler device, each automatic sprinkler device is provided with a booster pump, a wireless receiver and a controller, and the upper end of each automatic sprinkler device is provided with a spray pipe. The present invention can realize precise irrigation and fertilization, efficiently utilize water resources, and can also automatically spray water on the leaves to cool down and fertilize.

[0004] Although the equipment in the above document can irrigate and fertilize both the roots and stems of plants and the branches and leaves of plants, it still has obvious defects in actual use, such as:

[0005] When the device irrigates branches and leaves, it is necessary to use the guide rail to move the nozzle before spraying the branches and leaves. This method results in a small irrigation range for the branches and leaves, and each time the branches and leaves are irrigated, the nozzle position needs to be constantly moved and sprayed one by one, which is too inefficient. In addition, the device uses a spiral feeder rod to accurately feed fertilizer, but the spiral feeder rod is tilted, and the tilted spiral feeder rod does not have the function of locking the fertilizer. The fertilizer inside the storage barrel will leak along the spiral blades on the surface of the spiral feeder rod, making it impossible to store and affecting daily use.

[0006] Therefore, a smart agricultural water-saving irrigation and fertilization device is now designed to improve the efficiency of branch and leaf irrigation and to stably apply fertilizer to solve such defects. Summary of the invention

[0018] Beneficial Effects

[0019] The present invention provides a smart agricultural water-saving irrigation and fertilization device. Compared with the existing technology, it has the following beneficial effects:

[0020] (1) The smart agricultural water-saving irrigation and fertilization device combines the material changing and stirring mechanism and the irrigation switching mechanism. The two mechanisms can utilize the lifting and lowering of the cylinder to inject different fertilizers into the fertilizer melting water tank respectively, without causing fertilizer leakage to affect daily irrigation and storage. In this process, the linkage between the structures can be utilized to allow several upper spray pipes to rise synchronously and automatically rotate at a certain angle, so that branches and leaves can be sprayed over a large area, effectively improving the efficiency of irrigation and meeting current usage.

[0021] (2) The smart agricultural water-saving irrigation and fertilization device is equipped with a rectangular side plate at the front of the fertilizer melting water tank, and a plurality of curved tubes and conical frames are installed inside the rectangular side plate by using positioning pins. The device is used in combination with an upper spray pipe, a conical nozzle and a pressure plate. The arrangement of these structures enables the curved tube to be inserted into the soil for root and stem irrigation. The subsequent rise of the U-shaped frame can separate the conical nozzle from the conical frame and drive the upper spray pipe to flip, thereby achieving large-scale and comprehensive irrigation of branches and leaves. After the irrigation of branches and leaves is completed, the device can be reconnected with the conical frame, which is convenient for daily switching irrigation of roots and stems and branches and leaves.

[0022] (3) The smart agricultural water-saving irrigation and fertilization device is used by installing storage boxes on both sides of the top of the molten fertilizer water tank, and is used in combination with a first arc-shaped tooth plate and a second arc-shaped tooth plate. The arrangement of these structures can utilize the opposite staggered arrangement of the first arc-shaped tooth plate and the second arc-shaped tooth plate, so that when the cylinder is raised or lowered, it can utilize the meshing with the gear cylinder to inject different types of fertilizers into the interior of the molten fertilizer water tank respectively, and the injection amount is accurate, and fertilizer leakage will not occur, thereby ensuring stability in daily use.

[0023] (4) The smart agricultural water-saving irrigation and fertilization device has a second sealing plug and a first sealing plug fixedly connected to the opposite ends of the rectangular frame and the flip plate respectively, which are used in conjunction with the drain port. The arrangement of these structures can open and close the drain port when the cylinder is raised or lowered, so that the remaining fertilizer and water can be drained away in advance when spraying different fertilizers, thereby avoiding the influence of the mixture of different fertilizers and water on the plants after spraying.

[0040] When it is necessary to fertilize the branches and leaves of crops, the cylinder 115 is started to first drive the second arc-shaped tooth plate 120 and the vertical pressure column 122 to rise and reset. During this process, since the second arc-shaped tooth plate 120 is in the shape of arc-shaped teeth, it will shrink into the storage frame 118 and will not mesh with the gear cylinder 105. After the reset is completed, the cylinder 115 continues to rise.

After the U-shaped frame 207 rises, it uses the anti-flip rod 213 to drive the upper nozzle 209 to rise together and separate the conical nozzle 210 from the conical frame 205. When the first arc-shaped tooth plate 119 rises to the top, the two pressing plates 113 will press against the upper nozzle 209, so that the upper nozzle 2 09 rotates under the limit of the pressure plate 113, allowing the conical nozzle 210 to rotate at a sixty-degree angle to aim at the branches and leaves, and then start the water injection pipe 110 and the motor 106 again to inject water and stir, and then use the water pump 111 to spray the fertilizer water onto the branches and leaves through the conical nozzle 210. After the spraying of the branches and leaves is completed, start the cylinder 115 to descend to discharge the excess fertilizer water in the molten fertilizer water tank 101, and then insert the first sealing plug 124 into the drain port 109 to the initial position for daily watering.
