DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Example

[0026] A pre-buried agricultural sprinkler irrigation device, such as Figures 1 to 4 As shown, it includes a water supply pipe 1 and at least two connecting pipes 2 which are movably connected in sequence and whose diameters increase in sequence. In this embodiment, the water supply pipe 1 is located underground, there are four connecting pipes 2, and the connecting pipes 2 located inside can extend from the adjacent connecting pipes 2.

[0027] The water supply pipe 1 is connected to the outermost connecting pipe 2, and the remaining connecting pipes 2 are all provided with a limiting seat 3. The innermost connecting pipe 2 is installed with a nozzle 20, and a spray hole 19 is opened on the nozzle 20, and the end of the nozzle 20 is sharp. The remaining connecting pipes 2 are all provided with a limiting seat 4, and the limiting seat 4 is used to limit the adjacent limiting seat 3.

[0028] Specifically, a limiting step 6 is provided on the limiting seat 1 3. When the internal connecting tube 2 extends out from the adjacent connecting tube 2, the step surface of the limiting step 6 can abut against the lower end surface of the adjacent limiting seat 2 4, thereby preventing the internal connecting tube 2 from being completely separated from the adjacent connecting tube 2.

[0029] It should be noted that under the action of external force, when the innermost connecting tube 2 extends out from the adjacent connecting tube 2 by moving, the innermost connecting tube 2 drives the corresponding limit seat 3 to move until the step surface of the limit step 6 can abut against the lower end surface of the adjacent limit seat 2 4. At this time, the limit seat 2 4 is driven by the limit seat 1 3 to move, and the connecting tube 2 corresponding to the limit seat 2 4 also moves accordingly, thereby realizing that the connecting tube 2 drives the adjacent connecting tube 2 to move.

[0030] It should be noted that, under normal conditions, the internal connecting pipe 2 is located inside the adjacent connecting pipe 2, and the sprinkler irrigation device is completely underground at this time. Only during sprinkler irrigation, the internal connecting pipe 2 is extended from the adjacent connecting pipe 2 by external force, and the sprinkler head 20 is located above the ground at this time. Water flows out from the spray hole 19 for sprinkler irrigation. Under normal conditions, the sprinkler irrigation device is hidden underground to avoid accidental damage to the sprinkler irrigation device due to ground operations.

[0031] An elastic member is provided between two adjacent connecting pipes 2, and the elastic member is used to retract the connecting pipe 2 into the adjacent connecting pipe 2. After the sprinkler irrigation operation is completed, the connecting pipe 2 is retracted into the adjacent connecting pipe 2 by the elastic member, so that the sprinkler irrigation device is hidden underground again, thereby avoiding accidental damage to the sprinkler irrigation device due to ground operations. Moreover, no user operation is required, and it is more convenient to use.

[0032] The elastic member includes a spring 5, one end of which is in contact with or connected to the limit seat 1 3, and the other end of the spring 5 is in contact with or connected to the limit seat 2 4. It should be noted that when the internal connecting pipe 2 extends from the adjacent connecting pipe 2, the connecting pipe 2 drives the limit seat 1 3 and the limit seat 2 4 connected thereto to move, and the limit seat 1 3 and the limit seat 2 4 cooperate to squeeze the spring 5, so that the spring 5 is in a compressed state. When the sprinkler irrigation operation is completed and the external force applied to the connecting pipe 2 disappears, the elastic restoring force of the spring 5 pushes the limit seat 1 3 and the connecting pipe 2 connected thereto to move, so that the connecting pipe 2 retracts and resets to the adjacent connecting pipe 2.

[0033] As another solution, the elastic member adopts a tension spring, one end of which is connected to the connecting pipe 2, and the other end of the tension spring is connected to the adjacent connecting pipe 2. When the internal connecting pipe 2 extends out from the adjacent connecting pipe 2, the tension spring is deformed. When the sprinkler irrigation operation is completed and the external force applied to the connecting pipe 2 disappears, the elastic restoring force of the tension spring causes the connecting pipe 2 to retract and return to the adjacent connecting pipe 2.

[0034] An annular groove 8 is provided on the side wall of the limiting seat 3, and the side wall of the connecting pipe 2 is recessed inward to form a receiving groove 9 and an annular protrusion 10, and the annular protrusion 10 is embedded in the annular groove 8. The cooperation between the annular protrusion 10 and the annular groove 8 ensures the relative stability of the limiting seat 3 and the connecting pipe 2. A clamp 11 is provided on the outer wall of the connecting pipe 2, and the clamp 11 is located in the receiving groove 9. Under the action of the clamp 11, the limiting seat 3 and the connecting pipe 2 remain relatively stable.

[0035] Except for the limit seat 24 arranged on the outermost connecting tube 2, the outer side walls of the other limit seats 24 are provided with an annular groove 2 12, and the side wall of the connecting tube 2 is recessed inward to form a receiving groove 2 13 and an annular protrusion 2 14, and the annular protrusion 2 14 is embedded in the annular groove 2 12. The cooperation between the annular protrusion 2 14 and the annular groove 2 12 ensures the relative stability of the limit seat 2 4 and the connecting tube 2. The outer side wall of the connecting tube 2 is sleeved with a clamp 2 15, and the clamp 2 15 is located in the receiving groove 2 13. Under the action of the clamp 11, the limit seat 2 4 and the connecting tube 2 remain relatively stable.

[0036] The outermost connecting tube 2 is connected to a limiting cap 16, which is used to limit the limiting seat 24 arranged on the outermost connecting tube 2. The outermost limiting seat is pressed against the upper end of the connecting tube 2 by the limiting cap 16, thereby achieving its limitation.

[0037] Specifically, a seal 17 is provided between the limit cap 16 and the limit seat 2 4 provided on the outermost connecting tube 2, and the seal 17 abuts against the outer side wall of the adjacent connecting tube 2, the lower end face of the seal 17 abuts against the upper end face of the limit seat 2 4, and a pressure ring 21 is placed on the upper end face of the seal 17, and the limit cap 16 presses the pressure ring 21 against the upper end face of the seal 17.

[0038] It should be noted that, through the sealing effect of the seal 17, external soil impurities cannot enter, and the water in the connecting pipe 2 is prevented from leaking to the outside. In addition to the limit seat 2 4 set on the outermost connecting pipe 2, the inner wall of the remaining limit seats 2 4 and the adjacent connecting pipe 2 are provided with a seal 2 18. Through the sealing effect of the seal 2 18, external soil impurities are prevented from leaking into the connecting pipe 2, and the water in the connecting pipe 2 is prevented from leaking to the outside.

[0039] The upper end of the limit seat 3 can be abutted against the lower end of the adjacent limit seat 3. A positioning step 7 is provided on the water supply pipe 1. The lower end of a limit seat 3 abuts against the step surface of the positioning step 7, thereby ensuring that under normal conditions, each limit seat 3 and the connecting pipe 2 connected thereto are stable. Example

[0040] like Figures 5 and 6As shown, the difference between the second embodiment and the first embodiment is that there are three connecting pipes 2, and the number of the corresponding limiting seat 1 3 and the number of the limiting seat 2 4 are both two.

[0041] It should be noted that the number of connecting pipes 2 should be appropriately increased or decreased according to the actual needs of the user, and the number of the corresponding limiting seat 1 3 and the limiting seat 2 4 should be adaptively increased or decreased.

[0042] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
