Technical Field
The utility model belongs to the technical field of agricultural irrigation equipment, concretely relates to irrigate and use plastics hosepipe.
Background
Traditional plastic water hoses (particularly PE water hoses) are widely applied to irrigation systems for agricultural planting. After the traditional plastic water hose is laid on a planting field, a farmer needs to punch holes (drilling mounting holes) on the wall of the water hose at the irrigation site, and install water guide pipes (such as straight pipes and tee pipes) at the positions of the mounting holes so as to lead and distribute water out of the tee pipes.
A conventional water guide pipe is shown in fig. 1. The water guiding pipe 30 is formed with an annular groove 301, the diameter of the front end of the water guiding pipe 30 is slightly larger than that of the mounting hole 211 of the pipe wall 21, and the front end of the water guiding pipe forcibly expands the mounting hole 211 temporarily during mounting, so that the edge part of the pipe wall of the mounting hole 211 is plugged into the annular groove 301. However, the above method has the following disadvantages: when the water band needs to be withdrawn after being used each time, whether the water conduit piece 30 is pulled out or not has two difficulties: if the water guide pipe is pulled out, the water guide pipe must be inserted into the water guide pipe again when the water guide pipe is used next time, but the mounting hole of the plastic water band is difficult to bear repeated folding, the edge of the mounting hole is easy to crack or damage in the process of pulling out and inserting the water guide pipe once or twice, and the water guide pipe is difficult to form sealing fit with the front end of the water guide pipe; however, if the water guiding pipe 30 is not pulled out, the water hose cannot be rolled up, because the water guiding pipe 30 needs to perform a certain function (for example, a spray head is installed, or a water pipe needs to be tightly sleeved), so the axial length of the water guiding pipe needs to be long (generally exceeding about 5 cm), and the radius of the water guiding pipe is small, so the water hose is abrupt and not flat enough, and therefore the water hose cannot be rolled up under the condition of the water guiding pipe.
In view of the above problems, the ZL201420206774.5 chinese utility model provides a plastic water hose for irrigation, its structure is as shown in fig. 2, connect plastic nut 1 in the mounting hole 211 fixed position of plastic water hose pipe wall 21, plastic nut is formed with screw 13 (promptly with internal thread), plastic nut 1 an organic whole is moulded plastics and is formed with the annular protruding edge 12 to protruding extension all around, the annular protruding edge 12 adopts ultrasonic welding with the pipe wall of plastic water hose mounting hole 211 border region to be supporting to have the cavity water pipe spare of taking the external screw thread. When in use, the hollow water guide pipe is arranged on the screw hole 13 of the plastic nut to realize water guide; when the plastic water hose 21 is used and needs to be retracted, the hollow water guide pipe can be screwed away, and only the plastic nut 1 is left on the pipe wall 21 of the plastic water hose; because the plastic nut only needs to have the function of screwing the water guide pipe, the axial length of the plastic nut can be made to be very short, the outer diameter of the plastic nut is larger than the diameter of the front end of the water guide pipe, and the diameter of the annular convex edge 12 of the plastic nut is larger, so that the plastic nut 1 is very flat (compared with the traditional water guide pipe), the plastic nut cannot prevent the plastic water hose from being curled (wound), namely the water hose with the plastic nut can be wound. When the plastic water belt needs to be used next time, the plastic water belt only needs to be unwound and screwed with the water guide pipe, and the plastic plug can be screwed on the part without water distribution.
However, the applicant finds in production practice that the plastic hose for irrigation needs to be ultrasonically welded to the pipe wall of the edge region of the plastic hose mounting hole 211 due to the annular convex edge 12, and ultrasonic welding needs to be performed through ultrasonic heating until the annular convex edge is melted, so that the whole ultrasonic welding process is time-consuming, a plurality of plastic nuts 1 need to be welded to each plastic hose, the plastic nuts 1 cannot be welded simultaneously, and the plastic nuts can only be welded one by one, and therefore, much labor and much time are required for welding the plastic nuts to each plastic hose, and the product cost is increased.
