Description

Technical Field

[0001] The present invention relates to the field of irrigation equipment, and more specifically, to a water-saving high-yield irrigation equipment and method for japonica rice. Background Art

[0002] Japonica rice has relatively short stems, narrow leaves, dark green in color, short and thick grains that do not stick. The grains of japonica rice are broad and short, relatively thick, and oval or ovoid in shape. The grains have high strength and good pressure resistance, are not easily broken during processing, have a relatively high milling rate, and the cooked rice has a relatively small swelling property.

[0003] Existing water-saving irrigation methods include: Moist irrigation is a relatively water-saving irrigation method. In this method, the paddy field is kept in a moist state without forming an obvious water layer. Moist irrigation is suitable for areas with relatively tight water resources and can effectively reduce water evaporation and seepage losses. At the same time, moist irrigation is beneficial to soil aeration and promotes the growth of rice roots. However, this method requires more precise water management to ensure the normal growth of rice. Controlled irrigation is a method of precisely controlling the irrigation amount according to the growth needs of rice. By monitoring soil moisture and the growth status of rice, the appropriate irrigation time and irrigation amount are determined. Controlled irrigation can significantly improve water use efficiency, reduce waste, and ensure the healthy growth of rice. This method requires a relatively high technical level and equipment investment, but in the long run, it has significant economic and environmental benefits.

[0004] Currently, there is still a lack of a device that can easily disperse the water flow when the nozzle sprays water, achieving multi-directional and uniform spraying, thereby realizing water-saving irrigation for japonica rice. Summary of the Invention

[0006] The present invention adopts the following technical solutions to achieve the invention purpose: A water-saving and high-yield irrigation device and method for japonica rice, including a frame, characterized in that: the frame is fixedly connected to a water tank, the frame is rotatably connected to a set of trusses, each frame is bearing-connected to a set of second adjusting nuts, each second adjusting nut is respectively thread-connected to a second adjusting L-screw, the cross bars of each second adjusting L-screw respectively pass through the corresponding trusses, and the cross bars of each second adjusting L-screw are respectively thread-connected to locking nuts; each truss is respectively bearing-connected to a wheel axle, each wheel axle is respectively fixedly connected to an outer wheel through a set of spokes, each truss is respectively fixedly connected to a set of mounting rings, each mounting ring is respectively fixedly connected to a mounting strip, and each mounting strip is respectively fixedly connected to a mounting long shaft; each wheel axle is respectively fixedly connected to a driving bevel gear, each mounting long shaft is respectively bearing-connected to a driven bevel gear, each wheel axle respectively passes through the central shaft, mounting plate and cross plate of the driven bevel gear, and each driven bevel gear and each driving bevel gear respectively mesh with the corresponding driven bevel gear; the central shafts of each driven bevel gear are respectively fixedly connected to the corresponding mounting plates, each mounting plate is respectively fixedly connected to an inner wheel, each truss is respectively fixedly connected to a mounting L-plate, and each mounting L-plate is respectively fixedly connected to the corresponding cross plate; each cross plate is respectively fixedly connected to a set of mounting seats, each mounting seat is respectively fixedly connected to a piston cylinder, each piston cylinder is respectively fixedly communicated with a one-way water inlet valve, each piston cylinder is respectively provided with a piston column, each piston column is respectively fixedly connected to a water inlet pipe, and each water inlet pipe is respectively fixedly communicated with a spray head.

[0007] As a further limitation of this technical solution, the central shaft of a set of small gears is respectively bearing-connected to each cross plate, a power rod is respectively fixedly connected to the eccentric part of each small gear, each power rod is respectively rotatably connected to a transmission connecting rod, each transmission connecting rod is respectively rotatably connected to an L-shaped connecting rod, and each L-shaped connecting rod is respectively fixedly connected to the corresponding piston column.

[0008] As a further limitation of this technical solution, each wheel axle is respectively fixedly connected to a large gear, and each small gear respectively meshes with the corresponding large gear.

[0009] As a further limitation of this technical solution, a set of evenly distributed water distribution grilles is respectively fixedly connected to each outer wheel, a set of evenly distributed water scattering protrusions is respectively fixedly connected to each inner wheel, and a water scattering groove is respectively arranged on each inner wheel corresponding to the corresponding water scattering protrusion.

[0010] As a further limitation of the technical solution, the frame is rotatably connected to two groups of T plates, the frame is bearing-connected to two groups of first adjusting nuts, each of the first adjusting nuts is respectively threadedly connected to a first screw rod, the lower end of each first screw rod is respectively rotatably connected to the corresponding T plate, two inclined circular shafts of each T plate are respectively connected to a separating wheel, the lower part of each screw rod is respectively fixedly connected to a circular plate, the lower end of each spring is respectively fixedly connected to the corresponding circular plate, each spring is respectively sleeved around the corresponding screw rod, and the upper end of each spring is respectively fixedly connected to the frame.

[0011] As a further limitation of the technical solution, each group of four nozzles forms an angle of 45 degrees with the horizontal direction. By virtue of their different angular positions, the spraying distances of the two nozzles located above are far, and the spraying distances of the two nozzles located below are close.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: The four nozzles of this device are at an angle to the horizontal direction. By utilizing the different angular positions, the two nozzles at the upper part have a longer spraying distance, while the two nozzles at the lower part have a shorter spraying distance. By using a driven bevel gear and a driving bevel gear to respectively mesh and drive a transmission bevel gear, the driven bevel gear rotates in the opposite direction to the driving bevel gear, thereby realizing the reverse rotation of the outer wheel and the inner wheel. The two-stage reverse rotation scatters the water flow more, and when the sprayed water encounters the water-scattering protrusions, it will be scattered to both sides, and when it encounters the water-dividing grille, it will be sprayed forward, achieving multi-directional uniform spraying.
