Technical Field

[0001] The utility model relates to the field of agricultural irrigation technologies, and particularly relates to a sealing quick-connection device for an agricultural irrigation outlet pile. Background Art

[0002] The high-standard farmland outlet pile, namely the water outlet pile, is an important part of high-standard farmland construction and is mainly used for farmland irrigation and drainage. Its main function is to transport the water in the reservoir or the buried irrigation pipeline in the field to the farmland to meet the irrigation needs of crops. The outlet pile is connected to the water supply pipeline through a riser pipe and is equipped with a water outlet valve group to ensure that the water source can be smoothly transported to every corner of the farmland.

[0003] In the prior art, the improvements to the quick-connection device for the outlet pile are mostly reflected in the connection method. For example, the Chinese patent document with the publication number CN217463567U discloses a quick-connection assembly for an agricultural irrigation outlet pile, which includes a pipe joint that can be connected and installed on an underground pipeline and exposed on the ground. It further includes: a transition pipe for connecting the pipe joint, a cover for plugging the pipe joint, and a clamp assembly for clamping the transition pipe or the cover on the pipe joint; a circular convex ring is arranged radially at the open end of the pipe joint, and a circular ring with the same outer diameter as the convex ring protrudes on the outer surface of the transition pipe and the outer edge of the cover; the clamp assembly clamps and fixes the axially aligned convex ring and circular ring; the utility model makes the disassembly and assembly of the pipe joint exposed on the ground and the valve or pipe fitting more flexible and convenient, improving the disassembly and assembly efficiency of the agricultural irrigation pipe network; the cover can prevent the soil or withered branches and leaves in the field from falling into the outlet pile and avoid clogging of the agricultural irrigation pipe network; the cover can be extended to realize the connection of the outlet pile to an agricultural sprinkler or a position marking piece.

[0004] Although the above-mentioned improvement in the connection method has certain advantages, there are still deficiencies:

[0005] The above installation method mainly realizes fixed connection through the clamp assembly. This method is relatively slow when maintaining or replacing the valve, and repeated disassembly will cause thread damage. Content of the Utility Model

[0006] Therefore, to solve the above deficiencies, the utility model provides a sealing quick-connection device for an agricultural irrigation outlet pile.

[0007] To achieve the above object, the utility model adopts the following technical solutions: An out-ground pile sealing quick-connection device for agricultural irrigation, comprising a water inlet pipe, an electric three-way valve, a control switch, an inner ring and an outer ring. There are two groups of the water inlet pipes, which are symmetrically arranged left and right; the electric three-way valve is communicated with the water inlet pipe; a control switch is arranged on the top of the electric three-way valve, and the electric three-way valve is electrically connected with the control switch; a valve group connection thread is arranged on the outer surface of the top of the inner ring, and a limiting clamping table is arranged at the bottom of the inner ring; the outer ring includes an inner ring and an outer ring, and the inner ring is arranged inside the outer ring.

[0008] As a further scheme of the utility model, the inner ring is threadedly connected with the electric three-way valve through the valve group connection thread. The inner ring is detachably connected with the electric three-way valve, and the installation and disassembly between the inner ring and the electric three-way valve can be just achieved through the valve group connection thread.

[0009] As a further scheme of the utility model, there are multiple groups of the limiting clamping tables. Each group of the limiting clamping tables is evenly distributed along the outer surface of the inner ring at an angle of 120°. The limiting clamping tables are used for locking connection and sealing.

[0010] As a further scheme of the utility model, a groove is arranged on the outer surface of the inner ring, and a sealing ring is inserted into the groove. The groove is used for inserting and installing the sealing ring, and the sealing ring is used for playing a sealing role.

[0011] As a further scheme of the utility model, multiple groups of limiting clamping grooves are arranged on the inner side of the outer ring, and a limiting platform is arranged inside the limiting clamping grooves. The limiting clamping grooves and the limiting platform can achieve that the rotation angle each time is not greater than 120 degrees.

[0012] As a further scheme of the utility model, multiple groups of the limiting clamping grooves are evenly distributed at an angle of 120°. The limiting clamping grooves are clamped with the limiting clamping tables. Further preferably, the number of the limiting clamping grooves and the limiting clamping tables is adapted.

[0013] As a further scheme of the utility model, a water outlet pile connection port is further arranged inside the outer ring. The water outlet pile connection port is used for communicating with the out-ground pile. Further preferably, they can be connected by means of glue bonding.

[0014] Compared with the prior art, the utility model provides an out-ground pile sealing quick-connection device for agricultural irrigation, which has the following beneficial effects:

[0015] In the present utility model, by providing an inner ring and an outer ring, the outer ring can be connected to the ground outlet pile by means of gluing.
