Water-saving irrigation equipment for garden greening, comprising an irrigation equipment body (1), a transverse spraying assembly (2), a longitudinal spraying assembly (3), an elastic support member (4), and an adjustable water spraying pipe (5); the longitudinal spraying assembly (3) comprises a clamping disc (9), a triangular arc-shaped rotating member (10), a drive motor (11), a driving gear (12), a limiting gear (13), an upper limiting ring (14) and a lower limiting ring (15); and the transverse spraying assembly (2) comprises a rotation motor (18), a driving rotary shaft (19), a driving bevel gear (20), a first fixing member (21), a second rotating member (22), and a driven bevel gear (23). The present equipment belongs to the technical field of irrigation equipment for garden greening, and specifically, provided is water-saving irrigation equipment for garden greening, which enables the adjustable water spraying pipe (5) to move back and forth in transverse and longitudinal directions under the combined action of the transverse spraying assembly (2) and the longitudinal spraying assembly (3), so as to expand the area and range of irrigation, can also set the flow rate of water spraying according to needs, and is convenient to use, easy to adjust, and has an energy-saving effect.
A: A water spray device for a garden. The water spray device comprises: a base (1), and an installation plate (2) integrally formed with the base (1). A first set of two parallel snap strips (3) is disposed at the top of the base (1). The first snap strip set (3) is connected to a second snap strip set (5) via a first snap block (4). The second snap strip set (5) is snap-connected to a movable base (7). A water spray mechanism is disposed at the top of the movable base (7). The water spray mechanism comprises: a rotary disc (8), and a water storage tank (14) connected to the rotary disc (8) via a retractable rod (10). A side wall of the water storage tank (14) is provided with a large nozzle (12) and a small nozzle (11). A water injection port (13) is disposed at the top of the water storage tank (14). The first snap strip set (3) and the second snap strip set (5) are provided perpendicularly, so that the moving trajectory of a movable plate (9) is cross-shaped. The rotary disc (8) rotates, enabling the water spray mechanism to achieve a 360° water spray and a wider spray area. In addition, the side wall of the water storage tank (14) is provided with the large nozzle (12) and the small nozzle (11), so that the amount of water spray can be controlled on the basis of the growth of a plant. The water spray device for the garden is easy to use.
B: A wireless transmission intelligent control host water-saving irrigation device, comprising a bottom plate (15), wherein an upper surface of the bottom plate (15) is provided with a collecting box (2); a rear side of the collecting box (2) is fixedly connected to a supporting vertical plate (9); an upper surface of the supporting vertical plate (9) is fixedly connected to a placing seat (11); a front side surface of the placing seat (11) is fixedly connected to a water flow adjustment valve (10); the upper surface of the bottom plate (15) is fixedly connected to a sliding rod (17); an outer surface of the sliding rod (17) is connected to a sliding block (18) in a sliding manner; an upper surface of the sliding rod (17) is fixedly connected to a limiting plate (16); and an electric push rod (20) is arranged inside the bottom plate (15). According to the irrigation device, the irrigation angle and the height are convenient to adjust, and the operation is convenient.
C: An irrigation bracket for a greenhouse of flowers and plants, comprising a bracket plate (1), a linkage bin (2), a rotary driving device (3), a ventilating device (4) and a centrifugal adjustable scattering irrigation rig (5). The linkage bin (2) is provided on the bottom wall of the bracket plate (1), one end of the ventilating device (4) penetrates through the bottom wall of the linkage bin (2) and is provided on the upper wall in the linkage bin (2), the other end of the ventilating device (4) is provided outside the linkage bin (2), the rotary driving device (3) is provided on the upper wall of the bracket plate (1), one end of the rotary driving device (3) penetrates through the bracket plate (1) and the upper wall of the linkage bin (2) and is connected to the ventilating device (4), and the centrifugal adjustable scattering irrigation rig (5) is provided on the bottom wall of the linkage bin (2). The irrigation bracket belongs to the technical field of seedling raising of the flowers and plants. According to the irrigation bracket for the greenhouse of the flowers and plants, an outward-convex design serves as a receiving surface for receiving irrigating water, water is uniformly sprinkled to the flowers and plants in the greenhouse in the form of water drops by a size-adjustable centrifugal force, and the defect during the traditional irrigation that the volume of sprinkled water obtained by an area close to a center of circle and an area close to the outside of circumference is obviously smaller than that obtained by a middle area is overcome.
D: The present invention relates to the technical field of automatic filterable irrigation, and particularly relates to a filterable agricultural irrigation device, aiming to solve the problems that an existing agricultural irrigation device does not have a better function of filtering and collecting garbage during irrigation, and a spray head needs to be manually operated for spraying during irrigation, so that manpower is wasted. According to the following solution, the device comprises a base; a filter tank is fixedly mounted at the top of the base; a frame is fixedly mounted at the top of the filter tank; two telescopic rods are fixedly mounted at the top of the frame; one end of each of the two telescopic rods is fixedly connected to the same top base; a filter plate is fixedly mounted in the filter tank; a waterproof frame is fixedly mounted on the inner wall of the bottom of the filter tank; a first rotating rod is rotatably connected in the waterproof frame; a first bevel gear is fixedly connected to the first rotating rod. The present invention relates to a simple structure, angle convertible spraying is carried out by means of automatic height adjustment and automatic control, and people can use the device conveniently.
