Technical Field

[0001] The utility model relates to a drip irrigation pipe, in particular to a drip irrigation pipe with a flexibly detachable drip irrigation head. Background Art

[0002] Agricultural planting combined with drip irrigation technology has become a trend in current agricultural development. Drip irrigation pipes are generally laid on the ground and usually consist of water pipes and drippers. The drippers are set on the inner wall of the water pipes, forming a turbulent flow channel between the drippers and the water pipes. The water in the water pipes flows through the turbulent flow channel and is discharged from the water outlet of the water pipes.

[0003] Drip irrigation pipes are important irrigators in the drip irrigation system. According to the water requirements of crops, they use low-pressure pipe systems and emitters installed on capillary tubes to drip water and nutrients needed by crops drop by drop, evenly and slowly into the soil in the root zone of crops.

[0004] However, in the prior art, since the drip irrigation pipe's dripper head needs to be fixed with parts such as bolts, it is very inconvenient, and after the dripper head is pulled out, the drip irrigation pipe is prone to leaking. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a drip irrigation pipe with a flexibly detachable drip irrigation head.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A drip irrigation pipe with a flexibly detachable drip irrigation head comprises a drip irrigation pipe, a fixed pipe is fixedly installed on the outer surface of the drip irrigation pipe, a dripper head is movably installed on the outer side of the fixed pipe, a water outlet is provided on one side of the dripper head, a squeeze tube is provided on the other side of the dripper head, an external slot is provided between the squeeze tube and the inside of the dripper head, dripper head outer grooves are provided on the upper and lower sides of the outer surface of the dripper head, special-shaped rods are movably installed inside the dripper head outer grooves, dripper head inner grooves are provided on the upper and lower sides of the outer surface of the squeeze tube, the special-shaped rods are movably inserted into the inside of the dripper head inner groove, and a bending spring is movably installed between the special-shaped rod and the inside of the dripper head inner groove.

[0008] Preferably, both upper and lower sides of the outer surface of the fixed tube are provided with limiting arc grooves, one end of the special-shaped rod passes through the interior of the outer groove of the dropper head and extends to the outside of the dropper head, and the other end of the special-shaped rod is movably inserted into the interior of the limiting arc groove.

[0009] Preferably, a rotating groove is provided on the inner surface of the drip irrigation pipe, and baffles are fixedly installed on both sides of the drip irrigation pipe near the rotating groove, an upper rotating plate is rotatably installed near the top of the rotating groove, and a lower rotating plate is rotatably installed near the bottom of the rotating groove.

[0010] Preferably, the surfaces of the upper rotating plate and the lower rotating plate are provided with openings, the upper rotating plate and the lower rotating plate are installed in cooperation with each other, the inner sides of the upper rotating plate and the lower rotating plate are fixedly installed with rotating shafts, both ends of the rotating shafts are rotatably connected to the inner wall surface of the rotating groove, and torsion springs are movably installed on both sides of the rotating shafts.

[0011] Preferably, a buckle is fixedly mounted on one side of the drip irrigation pipe, and a socket is provided on the other side of the drip irrigation pipe, and the buckle is movably inserted into the socket on the surface of the other drip irrigation pipe.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Through the cooperation of the special-shaped rod and the limiting arc groove, when the device needs to install the dropper head, the dropper head can be moved to a position close to the fixed tube, and the extrusion tube is inserted into the interior of the fixed tube. Then, the two special-shaped rods are pulled toward the direction of the fixed tube to rotate the special-shaped rod inside the inner groove of the dropper head, and the end of the special-shaped rod is retracted into the interior of the inner groove of the dropper head. At this time, the dropper head is continued to be inserted toward the fixed tube. When the end of the special-shaped rod moves to the position of the limiting arc groove, the special-shaped rod is released. The special-shaped rod is subjected to the elastic potential energy of the bending spring and pops out and is stuck in the interior of the limiting arc groove, thereby limiting the position of the dropper head and realizing the installation of the dropper head. When the dropper head needs to be removed, the two special-shaped rods can be pulled in opposite directions to retract the special-shaped rod from the limiting arc groove to the interior of the inner groove of the dropper head. At this time, the dropper head can be directly pulled out, thereby realizing the function of flexible removal of the dropper head of the device and convenient use of the device.

[0014] 2. Through the cooperation of the upper rotating plate and the lower rotating plate, when the device is installing the drip head, the squeeze tube will hit the surface of the upper rotating plate and the lower rotating plate when it is inserted into the fixed tube, so that the upper rotating plate and the lower rotating plate will rotate toward the inside of the drip irrigation tube, thereby opening the opening of the fixed tube, so that water can enter the interior of the drip head through the fixed tube, and when the drip head is pulled out, the squeeze tube will no longer limit the upper rotating plate and the lower rotating plate. The upper rotating plate and the lower rotating plate will rebound by the elastic force of the torsion spring, thereby closing the connection position between the fixed tube and the drip irrigation tube, so that water cannot be discharged through the fixed tube, thereby avoiding the situation where the fixed tube will leak when drip irrigation is not performed without the use of the drip head.

At this time, the dropper head 4 is continued to be inserted into the direction of the fixed tube 12. When the end of the special-shaped rod 6 moves When the special-shaped rod 6 reaches the position of the limiting arc groove 17, the special-shaped rod 6 is released. The special-shaped rod 6 will be ejected and stuck into the inside of the limiting arc groove 17 by the elastic potential energy of the bending spring 15, thereby limiting the position of the dropper head 4 and then realizing the installation of the dropper head 4. When the dropper head 4 needs to be removed, the two special-shaped rods 6 can be pulled in opposite directions to retract the special-shaped rod 6 from the limiting arc groove 17 to the inside of the dropper head inner groove 14. At this time, the dropper head 4 can be directly pulled out, thereby realizing the function of flexible disassembly of the dropper head 4 of the device and facilitating the use of the device.

[0024] As the preferred technical solution of this embodiment, Figure 3 As shown, the upper and lower sides of the outer surface of the fixed tube 12 are provided with limiting arc grooves 17, one end of the special-shaped rod 6 passes through the interior of the dropper head outer groove 13 and extends to the outside of the dropper head 4, and the other end of the special-shaped rod 6 is movably inserted into the interior of the limiting arc groove 17.

[0025] As the preferred technical solution of this embodiment, Figure 4 As shown, the inner surface of the drip irrigation pipe 1 is provided with a rotation groove 16, and baffles 7 are fixedly installed on both sides of the drip irrigation pipe 1 near the rotation groove 16. An upper rotation plate 9 is rotatably installed near the top of the rotation groove 16, and a lower rotation plate 10 is rotatably installed near the bottom of the rotation groove 16.

[0026] The surfaces of the upper rotating plate 9 and the lower rotating plate 10 are both provided with openings, and the upper rotating plate 9 and the lower rotating plate 10 are installed in cooperation with each other. The inner sides of the upper rotating plate 9 and the lower rotating plate 10 are fixedly installed with rotating shafts, and both ends of the rotating shafts are rotatably connected to the inner wall surface of the rotating groove 16, and torsion springs are movably installed on both sides of the rotating shafts.

[0027] In this embodiment, through the cooperation of the upper rotating plate 9 and the lower rotating plate 10, when the device is installing the dripper head 4, the squeeze tube 8 will hit the surfaces of the upper rotating plate 9 and the lower rotating plate 10 when being inserted into the fixed tube 12, thereby causing the upper rotating plate 9 and the lower rotating plate 10 to rotate toward the inside of the drip irrigation pipe 1, thereby opening the opening of the fixed tube 12, allowing water to enter the interior of the dripper head 4 through the fixed tube 12, and when the dripper head 4 is pulled out, the squeeze tube 8 no longer limits the upper rotating plate 9 and the lower rotating plate 10, and the upper rotating plate 9 and the lower rotating plate 10 will rebound by the elastic force of the torsion spring, thereby closing the position where the fixed tube 12 is connected to the drip irrigation pipe 1, so that the water cannot be discharged through the fixed tube 12, thereby avoiding the situation where the fixed tube 12 leaks when the dripper head 4 is not needed for drip irrigation.

[0028] Working principle: When the device needs to install the dropper head 4, the dropper head 4 can be moved to a position close to the fixed tube 12, and the extrusion tube 8 is inserted into the fixed tube 12. Then, the two special-shaped rods 6 are pulled toward the fixed tube 12, so that the special-shaped rods 6 rotate inside the inner groove 14 of the dropper head, and the ends of the special-shaped rods 6 are retracted into the inner groove 14 of the dropper head. At this time, the dropper head 4 is continued to be inserted into the direction of the fixed tube 12. When the ends of the special-shaped rods 6 move to the position of the limiting arc groove 17, the special-shaped rods 6 are released. The special-shaped rods 6 are subjected to the elastic potential energy of the bending spring 15 and pop out and snap into the inside of the limiting arc groove 17, thereby limiting the position of the dropper head 4 and realizing the installation of the dropper head 4.

[0029] When the device is installing the dripper head 4, the squeezing tube 8 will hit the surfaces of the upper rotating plate 9 and the lower rotating plate 10 when it is inserted into the fixed tube 12, so that the upper rotating plate 9 and the lower rotating plate 10 are rotated toward the inside of the drip irrigation pipe 1, thereby opening the opening of the fixed tube 12, so that water can enter the interior of the dripper head 4 through the fixed tube 12, and when the dripper head 4 is pulled out, the squeezing tube 8 no longer limits the upper rotating plate 9 and the lower rotating plate 10, and the upper rotating plate 9 and the lower rotating plate 10 are rebounded by the elastic force of the torsion spring, thereby closing the connection position between the fixed tube 12 and the drip irrigation pipe 1, so that the water cannot be discharged through the fixed tube 12, thereby avoiding the situation where the fixed tube 12 leaks when the dripper head 4 is not needed for drip irrigation;

[0030] When the dropper head 4 needs to be removed, the two special-shaped rods 6 can be pulled in opposite directions to retract the special-shaped rods 6 from the limiting arc groove 17 to the inside of the dropper head inner groove 14. At this time, the dropper head 4 can be directly pulled out, thereby realizing the function of flexible removal of the dropper head 4 of the device and facilitating the use of the device;

[0031] When installing the drip irrigation pipe 1, the buckle 2 can be inserted into the inside of the socket 3 to realize the combination and installation of multiple drip irrigation pipes 1. Therefore, multiple drip irrigation pipes 1 can be combined according to needs to increase the overall length of the drip irrigation pipe 1, thereby facilitating drip irrigation in different situations.
