[0002] In the field of greenhouse cultivation, irrigation is a key link to ensure crop growth. First, water waste is prominent. Traditional irrigation methods mostly use flood irrigation or fixed sprinkler spraying, with a water utilization rate of only about 40%. A large amount of water is lost due to evaporation and seepage, especially in arid areas where the contradiction between water supply and demand is more acute.

[0003] Most fixed irrigation equipment has limited coverage and cannot accurately control the water demand according to the different growth stages and water requirements of crops in different areas of the greenhouse. This can easily lead to over-irrigation in some areas and under-irrigation in others, affecting the uniformity of crop growth. In addition, the equipment is fixed in height and cannot adapt to the irrigation needs of crops of different heights. For vines or tall crops, there are often irrigation blind spots. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a water-saving irrigation facility for greenhouses, comprising four electric actuators 1 arranged in a rectangular pattern and installed on a concrete surface. Two water tanks 2 are symmetrically installed between the opposite faces of the four actuators 1. Two water collection troughs 3 are symmetrically arranged on both sides of each water tank 2, with drainage pipes connected to the water tanks 2 at both ends. The four electric actuators 1 are grouped into two groups of two closer actuators each, and each group of actuators 1 has a mounting platform 4 fixedly attached to its top. Hollow tube frames 5 are installed between the opposite faces of the mounting platforms 4. The electric actuators 1 are of model DTZ200, and their stroke can be customized. The water collection troughs 3 are made of HDPE, which is UV-resistant and corrosion-resistant. This structure, through the cooperation of the water collection troughs 3 and the water tanks 2, facilitates the collection and storage of rainwater, improving water resource utilization and thus realizing rainwater recycling. One of the mounting platforms 4 has two guide wheels 6 symmetrically arranged on its top surface, and the other mounting platform 4 has a first rotating shaft frame 7 installed in the center of its top surface. One end of the frame 7 is equipped with a guide wheel 6 made of polyurethane coated wheel, which is wear-resistant and has a good noise reduction effect; the first rotating shaft frame 7 is welded from Q235 steel, with a stable structure; the guide wheel 6 guides the wire rope 9, which facilitates the smooth movement of the wire rope 9, improves the stability of the transmission, and thus realizes the guiding function of the spray frame movement; the wire rope 9 is wound on the shaft of the first rotating shaft frame 7, and one end of the wire rope 9 passes through two guide wheels 6 in sequence and is wound and installed on the shaft of the second rotating shaft frame 8. One end is equipped with a drive motor 10 that is coaxially fixed to its internal rotating shaft. The other end of the first rotating shaft frame 7 is coaxially fixed to a drive gear. A dust cover is installed between the first rotating shaft frame 7 and the second rotating shaft frame 8. The model of the drive motor 10 is 5IK120RGN-CF. The wire rope 9 adopts a 6×19+IWS structure. The drive motor 10 drives the first rotating shaft frame 7 and the second rotating shaft frame 8 to rotate, which facilitates the winding and unwinding of the wire rope 9, improves the flexibility of the sprinkler frame movement, and thus realizes the function of adjusting the irrigation range.

[0020] In this utility model, a driven gear that meshes with the driving gear is coaxially fixed to one end of the second rotating shaft frame 8. A horizontal plate 11 is fixedly installed on the part of the wire rope 9 located between the first rotating shaft frame 7 and the guide wheel 6. A through hole is opened on the horizontal plate 11 for the part of the wire rope 9 between the second rotating shaft frame 8 and the guide wheel 6 to pass through. Two vertical rods are symmetrically arranged on one side of the top surface of the two mounting platforms 4, and a guide rod is installed between the two vertical rods. A guide hole is opened on one side of the horizontal plate 11 for the guide rod to pass through. Both the driven gear and the driving gear are made of 40Cr material and are quenched. The guide rod is a chrome-plated optical shaft. Through the gear meshing transmission and the cooperation of the guide rod, it is easy to accurately control the movement of the horizontal plate 11, improve the accuracy of the sprinkler frame positioning, and thus realize the precise irrigation function. A sprinkler frame is fixedly installed on the bottom surface of the horizontal plate 11. Multiple nozzles are equidistantly suspended on the bottom surface of the sprinkler frame. The two ends of the hollow tube frame 5 are connected to the... Two inlet pipes 12 are spirally wound at the corners. Two pumps 13, connected to the inside of the water tanks 2, are installed diagonally at the top of the two water tanks 2. One end of the inlet pipe 12 passes through the hollow pipe frame 5 and is connected to the pump 13. The other end of the inlet pipe 12 is connected to both ends of the sprinkler frame. The pump 13 is model ISG50-160. The sprinkler head is a fan-shaped atomizing nozzle with a spray angle of 90°. Through the cooperation of the pump 13, the inlet pipe 12, the sprinkler frame, and the sprinkler head, water can be sprayed evenly, improving the uniformity of irrigation and thus achieving efficient irrigation. The water collection trough 3 has symmetrical wing plates installed on both sides. Multiple ground nails are installed at equal intervals on the bottom surface of the wing plates. A screen plate is installed on the top surface of the water collection trough 3. The wing plates are made of Q235 steel plate. The screen plate is made of stainless steel perforated plate. Through the cooperation of the wing plates and the ground nails, the water collection trough 3 is easily fixed, improving its stability and thus achieving reliable installation of the water collection trough 3.

[0021] Working Principle: In the use of this utility model, firstly, during rainfall, the rainwater collection trough 3 filters rainwater through the sieve plate on its top surface. The filtered rainwater flows into the water tank 2 for storage through the drain pipe. The wing plate and ground nails work together to enhance the stability of the rainwater collection trough 3 and prevent it from shifting under the impact of rainwater. When irrigation is needed, the pump 13 is started, and the water in the water tank 2 is transported to the sprinkler frame through the inlet pipe 12. Then, it is evenly sprayed onto the crops through multiple nozzles on the bottom surface of the sprinkler frame. If it is necessary to adjust the irrigation height, the electric actuator 1 is started. The electric actuator 1 extends and retracts, driving the mounting platform 4 to rise and fall, thereby causing the hollow tube frame 5 and the associated sprinkler frame to rise and fall synchronously to adapt to the irrigation needs of crops at different heights. When it is necessary to adjust the lateral range of irrigation, the drive motor 10 works, driving the shaft of the first rotating shaft frame 7 to rotate. The drive gear follows the shaft. The rotation of the first shaft frame 7 drives the driven gear to rotate, causing the second shaft frame 8 to rotate synchronously. At this time, when the shaft of the first shaft frame 7 rotates clockwise, it winds the steel wire rope 9, while the shaft of the second shaft frame 8 rotates counterclockwise to release the steel wire rope 9. Conversely, when the shaft of the first shaft frame 7 rotates counterclockwise to release the steel wire rope 9, the shaft of the second shaft frame 8 rotates clockwise to wind the steel wire rope 9. Through this winding and unwinding coordination, the steel wire rope 9, guided by the guide wheel 6, drives the horizontal plate 11 to move along the guide rod. The horizontal plate 11 then drives the spray frame to move. The dust cover can prevent dust from entering the gear meshing point of the first shaft frame 7 and the second shaft frame 8 and affecting the transmission. By moving the spray frame, the irrigation coverage area is expanded, and precise irrigation of crops in different areas of the greenhouse is achieved. At this point, the device is in use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
