[0023] The present application provides an irrigation device for an agricultural greenhouse with a telescopic spray assembly 2. Specifically, when in use, first, the entire device is placed in a suitable position under the action of a base 4. Then, according to the different positions and heights of the crops in the greenhouse that need to be irrigated, the lifting assembly and the folding assembly on the telescopic spray assembly can be started to adjust the position of the spray assembly 23. After reaching the appropriate position, the storage assembly 3 can be started to transport water to the inside of the spray assembly 23 to complete the irrigation of the crops in the greenhouse. In the present application, multiple irrigation devices can be arranged at equal intervals according to the length of the greenhouse, so as to achieve a large-scale and thorough spraying work inside the greenhouse.

[0025] Further, according to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the folding assembly includes a folding and unfolding assembly 22 and a moving assembly 24. The moving assembly 24 is arranged outside the rotating screw rod 21 and is threadedly connected to the rotating screw rod 21. The folding and unfolding assemblies 22 are arranged at equal intervals outside the moving assembly 24.

[0026] The folding and unfolding assembly 22 includes a first rotating rod 221, a second rotating rod 222, a connecting shaft 223 and an intermediate shaft 224. The first rotating rod 221 and the second rotating rod 222 are alternately arranged, and an intermediate shaft 224 is arranged between the two. The first rotating rod 221 and the second rotating rod 222 between adjacent folding and unfolding assemblies 22 are connected to each other through the connecting shaft 223.

[0027] The moving assembly 24 includes a fixed frame 241, an intermediate tube 242, a fixed sleeve 243, a moving sleeve 244, an active sleeve 245 and a driving assembly 246. The interface of the fixed frame 241 is arranged in a "U"-shaped structure, and the intermediate tube 242 is fixed to the top thereof. The intermediate tube 242 is provided with a threaded hole inside thereof and is threadedly connected with the threaded structure outside the rotating screw 21. A fixed fixing sleeve 243 is arranged above the outside of the intermediate tube 242, and a moving sleeve 244 penetrating therewith is arranged below the outside thereof. The bottom of the movable sleeve 244 is coaxially connected to the active sleeve 245, and the outside of the active sleeve 245 is provided with a driving component 246 for driving the active sleeve 245 to rotate; The top end of the fixed sleeve 243 is axially connected to the first rotating rod 221 on the innermost folding and unfolding component 22 through an axis, and the top end of the movable sleeve 244 is axially connected to the second rotating rod 222 on the innermost folding and unfolding component 22 through an axis, and the first rotating rod 221 and the second rotating rod 222 on the innermost folding and unfolding component 22 move inside the reserved slide groove 11.

[0028] The top view of the active sleeve 245 is a gear-shaped structure, and a threaded hole is provided inside the active sleeve 245, and the threaded structure inside the threaded hole is threadedly connected with the threaded structure outside the intermediate tube 242; The driving assembly 246 includes a driving motor 2461 and a driving gear 2462 . The driving gear 2462 is disposed at the top of the driving motor 2461 , and the outside of the driving gear 2462 is threadedly connected to the driving sleeve 245 . The bottom of the driving motor 2461 is fixed to the bottom of the fixed frame 241 .

[0029] The spray assembly 23 is connected between the intermediate shafts 224 on the symmetrically arranged stowage and expansion assembly 22, and the spray assembly 23 includes a fixed pipe 231 and a high-pressure nozzle 232. The high-pressure nozzle 232 is evenly distributed on the bottom of the fixed pipe 231, and one side of the fixed pipe 231 is threadedly connected to the internal hollow structure of the intermediate shaft 224 through a connecting pipe 6, and the other side of the hollow structure of the intermediate shaft 224 is connected to the connecting pipe assembly 5 through the connecting pipe 6; In the present application, when the rotating screw 21 rotates, it will first be threadedly connected with the intermediate tube 242 on the moving assembly 24, so that the entire intermediate tube 242 and the fixed frame 241 outside it move up and down outside the rotating screw 21, thereby making the entire fixed frame 241 drive the upper retracting and unfolding assembly 22 and the spray assembly 23 to move up and down, completing the height change work; After the height change is completed, it is necessary to adjust the position of each spray component 23. At this time, it is necessary to start the driving motor 2461 on the driving component 246 to drive the driving gear 2462 at its top to rotate. When the driving gear 2462 rotates, it will mesh with the outside of the active sleeve 245, so that the driving gear 2462 rotates and is threadedly connected to the outside of the intermediate tube 242, thereby making the movable sleeve 244 at its top move up and down. When it moves up and down, the second rotating rod 222 at its top, which is axially connected to it, rotates around the outside of the intermediate shaft 224. The rotation work further causes the first rotating rod 221 and the second rotating rod 222 to cross-rotate, thereby the first rotating rod 221 and the second rotating rod 222 on each retracting and unfolding component 22 cross-rotate, thereby the distance between the intermediate shafts 224 on each retracting and unfolding component 22 changes, and further the distance between the spray components 23 passing through the intermediate shafts 224 changes, thereby achieving the effect of adjusting the spacing, and then, the effect of precise spraying of crops in the greenhouse can be achieved, so there will be no serious waste of water resources.

[0030] Specifically, according to Fig.10 and Fig.11 As shown, the storage assembly 3 includes a storage water tank 31 and a connecting pump 32 .

One side of the connecting main pipe 51 is connected to the connecting pump 32, and the other side thereof penetrates the innermost spray assembly 23. Adjacent spray assemblies 23 are connected via the connecting branch pipe 52. Specifically, when spraying, it is first necessary to fill the storage water tank 31 with water, and then start the connecting pump 32 to pump water, so that the water source reaches the inside of each connecting branch pipe 52 through the connecting main pipe 51. Since the connecting branch pipe 52 is penetrated by the hollow structure inside the intermediate shaft 224 through the connecting pipe 6, and the other side of the intermediate shaft 224 is also penetrated by the interior of the fixed pipe 231 through the connecting pipe 6, the water source will reach the position of the high-pressure nozzle 232 and spray out to achieve the effect of crop irrigation.
