Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural irrigation, in particular to a quick connection assembly for agricultural irrigation out-of-ground pile. BACKGROUND

[0002] Modern large-scale agricultural planting requires large-area irrigation of crops, and thus requires large-area laying or burying of water supply pipe networks in the field to construct water infiltration drip irrigation or sprinkling irrigation systems. The buried water pipe network is connected to a vertical water supply and drainage pipe (out-of-ground pile) that is exposed to the ground, and an external water source pipe is connected to the out-of-ground pile. The out-of-ground pile can be used to irrigate the field soil through the buried water infiltration pipe network. Alternatively, a self-powered rotating sprinkler is installed at the top of the out-of-ground pile, and the buried water pipe network sprays water to crops through the sprinkler of the out-of-ground pile. However, the current out-of-ground pile has the following problems: ① The out-of-ground pile is permanently fixed to the external water source pipe by adhesive connection, which requires cutting and breaking of the external water source pipe during disassembly and reinstallation of the external water source pipe, affecting the disassembly and assembly efficiency of the agricultural irrigation pipe network; ② After the out-of-ground pile is disassembled from the external water pipe, the pile pipe opening is exposed. To prevent dirt or crop branches and leaves from falling into the pile pipe opening, a colorful plastic bag or plastic film is used to cover and mark the pile pipe opening, and then a rope or adhesive tape is used to bind it. The protective effect of the thin plastic bag or plastic film is poor, and it is often damaged, resulting in ineffective protection of the pile pipe opening. Moreover, this protective operation of the pile pipe opening is inefficient and generates a large amount of plastic bag or plastic film waste when the plastic bag is removed. SUMMARY

[0003] To solve the above problems, the present application provides a quick connection assembly for agricultural irrigation out-of-ground pile, which can quickly install and disassemble the out-of-ground pile with valves, pipe fittings, etc., and can also quickly disassemble and assemble the out-of-ground pile sealing protection member. In addition, the out-of-ground pile can be connected to an agricultural water sprayer or a position marking member.

[0004] To achieve the above purpose, the present application provides a quick connection assembly for agricultural irrigation out-of-ground pile, which comprises a pipe joint that can be connected and installed on an underground pipe and exposed to the ground. The pipe joint further comprises a connecting pipe for connecting the pipe joint, a cover for sealing the pipe joint, and a clamp assembly for clamping the connecting pipe or the cover on the pipe joint. A circular protruding ring is provided on the radial direction of the opening end of the pipe joint. A circular ring with the same outer diameter as the protruding ring is protrudingly provided on the outer surface of the connecting pipe and the outer edge of the cover. The clamp assembly clamps and fixes the axially aligned protruding ring and circular ring.

[0005] The inner wall of the pipe joint with the convex ring alignment of the present invention is provided with a concave ring groove, and a rubber sealing ring is embedded in the concave ring groove. The rubber sealing ring forms a seal when the adapter or cap is clamped on the pipe joint.

[0006] One side of the ring on the adapter pipe of the present invention is a straight insertion pipe for insertion into the pipe connector, and the other side of the ring on the adapter pipe is an outer pipe. When the straight insertion pipe is inserted into the pipe connector, the rubber sealing ring is pressed against the outer wall of the straight insertion pipe and the inner wall of the pipe connector for sealing. The pipe connector is pre-connected to the ground pile, and the outer pipe is used to connect to the valve and water fittings. It is used to insert the straight insertion pipe into the pipe connector. The adapter pipe and the pipe connector are clamped and fixed by the clamp assembly, which can realize the quick installation function of the ground pile and the valve and water fittings. When disassembling, the clamp assembly is removed and the adapter pipe is pulled out of the pipe connector, which can realize the quick disassembly function of the valve and water fittings being separated from the pipe connector exposed above the ground.

[0007] The external connector of the present invention is a straight pipe or a bend, and the external connector preferred in the present invention is a straight pipe.

[0008] The cap of the present invention has a cylindrical plug portion that is fitted into the pipe joint, and a ring on the cap is disposed at the top edge of the cylindrical plug portion. When the cylindrical plug portion is fitted into the pipe joint, the rubber sealing ring is pressed against the outer wall of the cylindrical plug portion and the inner wall of the pipe joint for sealing. The ring on the cap and the convex ring on the pipe joint are axially fitted and aligned. After the adapter pipe is removed, the cap is fitted into the pipe joint and the cap is clamped and fixed to the pipe joint with a clamp assembly. This can prevent soil from the field and dead branches and leaves of crops from falling into the pipe joint and clogging the groundwater pipe network, thus playing a protective role.

[0009] The cap of the present invention has a cylindrical plug at the center of the top surface with a hole for functional expansion assembly. The hole can be used to insert a flag indicating the location of the pipe joint so that farmers know the location of the pipe joint (i.e., the ground stake) in the field.

[0010] The present invention has a blind hole inside the orifice column that can be punctured to connect the inside and outside of the cylindrical plug. When water testing is required, the thin bottom wall of the blind hole can be punctured to connect the inside and outside of the cylindrical plug through the orifice column. Once the orifice column is connected to the pipe joint and communicates with the inner cavity of the ground pile, the orifice column can also be modified into an irrigation water device such as a water spray head or water spray column, thereby expanding its usage function.

[0011] The clamping assembly of the present invention includes two opposing semi-circular clamps. The opposing surfaces of the two clamps are provided with clamping grooves for clamping the convex ring and the circular ring together. By clamping the convex ring and the circular ring together in axial fit and alignment through the clamping grooves of the two clamps, the function of clamping and fixing the adapter pipe or cap onto the pipe joint can be realized.

[0012] The clamp assembly of the present invention also includes bolts and nuts. Each clamp has a wing at both ends for through-hole connection. The wing of the two clamps is connected in series with bolts. The nut is screwed into the bolt to press the wing, so that the adapter pipe or cap can be clamped and fixed on the pipe joint.

[0013] The nut of this invention is a butterfly nut that is easy to turn by hand, which facilitates the quick installation or removal of the clamp assembly, making the installation or removal of the adapter or cap on the pipe joint more convenient.

[0014] The beneficial effects of this invention are as follows:

[0015] ① Makes the disassembly and assembly of exposed pipe joints, valves or fittings more flexible and convenient, and improves the disassembly and assembly efficiency of agricultural irrigation pipe networks.

[0016] ② Covering the ground outlet can prevent soil or dead leaves from falling into the outlet pile, thus avoiding blockage of the agricultural irrigation network; ③ Covering the ground outlet can be extended to allow for the connection of agricultural sprinklers or location markers.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 Figure 2 , Figure 4 and Figure 7 The diagram shows a quick-connect assembly for agricultural irrigation ground stakes, comprising a pipe connector 10 that can be connected to an underground pipe and protrudes above the ground. It also includes: an adapter pipe 20 for connecting the pipe connector 10, a cap 30 for sealing the pipe connector 10, and a clamping assembly 40 for clamping the adapter pipe 20 or the cap 30 onto the pipe connector 10. A circular convex ring A is radially arranged at the open end of the pipe connector 10, and a circular ring B with the same outer diameter as the convex ring A protrudes from the outer surface of the adapter pipe 20 and the outer edge of the cap 30. The clamping assembly 40 clamps and fixes the convex ring A and the circular ring B, which are axially aligned and fitted together.

[0034] The detailed structure of each component of this invention is described below.

[0035] like Figure 3 , Figure 1 and Figure 6 As shown, in the pipe joint 10 of the present invention, a concave annular groove 11 is provided on the inner wall of the pipe joint 10 with the convex ring A aligned, and a rubber sealing ring 50 is embedded in the concave annular groove 11.

[0036] like Figures 1 to 3 As shown, the adapter pipe 20 of the present invention has a straight insertion pipe 21 on one side of the ring B on the adapter pipe 20 for insertion into the pipe connector 10, and an outer pipe 22 on the other side of the ring B on the adapter pipe 20. The outer pipe 22 is a straight pipe coaxial with the straight insertion pipe 21.

[0037] like Figure 1 , Figure 2 , Figures 6 to 8As shown, the cover 30 of the present invention has a cylindrical plug portion 31 that can be fitted into the pipe connector 10. A ring B on the cover 30 is provided on the top edge of the cylindrical plug portion 31. A post 32 for functional expansion assembly is provided on the cylindrical plug portion 31 at the center of the top surface of the cover 30. A blind hole 33 is provided in the post 32 that can be punctured to make the cylindrical plug portion 31 communicate with the inside and outside.

[0038] like Figures 1 to 4 , Figure 6 and Figure 7 As shown, the clamping assembly 40 of the present invention includes two opposing semi-circular clamps 41. The opposing surfaces of the two clamps 41 are provided with clamping grooves 411 for clamping and pressing the convex ring A and the circular ring B together. The clamping assembly 40 also includes bolts 42 and nuts 43. Each clamp 41 has convex wings 412 for through-hole connection at both ends. The convex wings 412 of the two clamps 41 are connected in series with bolts 42. Nuts 43 can be screwed to bolts 42 to press the convex wings 412. The nuts 43 of the present invention are butterfly nuts that are easy to turn by hand.

[0039] The assembly structure and working principle of the present invention are described in detail below.

[0040] like Figures 1 to 5 As shown, the quick installation and removal of the adapter pipe 20 on the pipe joint 10 is as follows: Connect the pipe joint 10 to the underground agricultural irrigation network and expose it above the ground. Connect the outer pipe 22 on the adapter pipe 20 to a water valve or water supply and drainage fitting. Then, align the straight insertion pipe 21 on the adapter pipe 20 with the open end of the pipe joint 10 and insert it into place. The ring B on the adapter pipe 20 and the convex ring A on the pipe joint 10 are axially aligned and flush. The rubber sealing ring 50 is pressed between the outer wall of the straight insertion pipe 21 and the inner wall of the pipe joint 10 to seal. The two sleeves 41 of the clamping assembly 40 are aligned with the overlapping positions of the circular ring B and the convex ring A. The clamping grooves 411 of the two sleeves 41 clamp the circular ring B and the convex ring A. The convex wings 412 of the two sleeves 41 are connected in series with bolts 42. Then, the butterfly nut 43 is threaded to the bolts 42, and the nut 43 is tightened to press the convex wing 412. At this point, the quick clamping connection of the adapter pipe 20 on the pipe joint 10 is achieved, that is, the quick connection between the ground pile of the agricultural irrigation pipeline network and the water valve or water supply and drainage pipe fitting is realized. When it is necessary to separate the water valve or water supply and drainage pipe fitting from the ground pile, simply loosen the nut 43 manually, remove the two sleeves 41, so that the clamping grooves 411 are disengaged from the circular ring B and the convex ring A, and the straight insertion pipe 21 on the adapter pipe 20 can be pulled out from the pipe joint 10, thus realizing the quick disassembly and separation of the water valve or water supply and drainage pipe fitting from the ground pile.

[0041] The quick installation and disassembly of the adapter pipe 20 on the pipe joint 10 of this invention makes it more convenient to connect and disassemble the ground piles of agricultural irrigation pipelines with external water valves, water supply and drainage pipe fittings, etc.

[0042] likeFigure 1 , Figure 2 , Figures 6 to 8 As shown, the cap 30 is quickly installed and removed from the pipe fitting 10:

[0043] After removing the adapter pipe 20 from the pipe joint 10, to prevent soil or debris such as dead branches and leaves from falling into the ground pile through the pipe joint 10, the cylindrical plug portion 31 of the cap 30 of this invention is fitted into the open end of the pipe joint 10, so that the ring B of the cap 30 and the convex ring A on the pipe joint 10 are axially aligned and flush. The rubber sealing ring 50 is pressed against the outer wall of the cylindrical plug portion 31 and the inner wall of the pipe joint 10 for sealing. Then, the two clamps 41 of the clamp assembly 40 are aligned with each other at the overlapping position of the ring B of the cap 30 and the convex ring A of the pipe joint 10. The clamping groove 411 of sleeve 41 clamps the overlapping circular ring B and convex ring A. Then, the opposing convex wings 412 of the two sleeves 41 are connected in series with bolts 42. Then, the butterfly nut 43 is threaded to the bolts 42, and the nut 43 is tightened to press the convex wings 412, thus achieving the sleeve clamping and fixing of the cover 30 on the pipe joint 10. When water testing is required, the thin wall of the blind hole 33 in the perforated column 32 can be punctured to make the cylindrical plug part 31 open to the outside. The perforated column 32 can be used to insert flags to mark the location of the ground stakes so that farmers know the location of the ground stakes in the field. Furthermore, after the blind hole 33 is punctured to make the cylindrical plug part 31 open to the outside, small-diameter water pipe fittings, self-powered rotary sprinklers and other agricultural sprinkler irrigation water appliances can also be installed on the perforated column 32, expanding the application functions of the invention.

[0044] like Figure 7 and Figure 6 As shown, when it is necessary to quickly remove the cover 30 from the pipe joint 10, simply manually turn the nut 43 to disengage it from the bolt 42, remove the clamp assembly 40, and disengage the clamp groove 411 of the sleeve 41 from the ring B of the cover 30 and the convex ring A of the pipe joint 10. Then the cover 30 can be pulled out from the open end of the pipe joint 10, thus removing the protection of the cover 30 against falling debris from the ground pile.

[0045] The above embodiments are for illustrative purposes only and are not intended to limit the invention. Those skilled in the art can make various modifications or variations without departing from the spirit and scope of the invention. Therefore, all equivalent technical solutions should also fall within the scope of the invention, as defined by the claims.
