[0002] Drip irrigation can greatly improve the utilization rate of water resources. At present, drip irrigation is widely used in agricultural irrigation. Drip irrigation is to use drip irrigation pipes to deliver water to the roots of crops for local irrigation. The drip irrigation pipe production equipment includes a drip irrigation pipe extruder. A mold is installed at the outlet of the drip irrigation pipe extruder. A dripper conveying device is installed on the rear side of the mold. The rear side of the outlet of the dripper conveying device is an automatic conveying mechanism of the drip irrigation pipe. A pipe traction device is installed on the front side of the mold. A punching device is installed on the front side of the pipe traction device. When the drip irrigation pipe is produced, the drip irrigation pipe is extruded by an extruder. During the extrusion process, the automatic conveying mechanism and the dripper conveying device convey the dripper to the mold, so that the dripper is directly inlaid in the extruded drip irrigation pipe capillary tube. Then the drip irrigation pipe with the dripper moves to the punching device through the pipe traction device, and the drip irrigation pipe surface corresponding to the dripper position is punched.

[0003] At present, the waste generated during drilling is scattered and accumulated everywhere, which affects the environmental sanitation of the working area on the one hand, and the long-term accumulation of waste can easily affect the passage of the drip irrigation pipe and the normal drilling operation on the other hand, requiring the staff to stop the machine regularly for cleaning, resulting in low work efficiency and great difficulty in cleaning.

[0024] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0025] like Figure 1-6 As shown, it includes a punching mechanism for punching holes on the surface of the drip irrigation pipe, a mounting mechanism for limiting the punching mechanism, and a debris suction mechanism for sucking away waste debris.

[0026] The punching mechanism includes a pneumatic punching knife, which includes a rod-shaped knife seat 1 and a cutter head 2 detachably mounted on the knife seat 1. The cutter head 2 is hollow inside, and includes a connecting portion 21 connected to the knife seat 1 and an opening portion 22 for opening a hole in the drip irrigation pipe. The diameter of the opening portion 22 gradually decreases from the back to the front to form a funnel-shaped structure. A plurality of notches 23 are evenly opened at the front end of the opening portion 22. The notches 23 gradually increase from the front to the back, and expand to form an arc shape at the rear of the notch 23. The above structure of the cutter head 2 forms a sawtooth-like structure at the front end of the opening portion 22. On the one hand, it can accurately and quickly punch holes and keep the waste chips generated by punching in the cutter head 2, and the waste chips will not fly everywhere. On the other hand, it can enhance the strength of the opening portion 22 and extend the service life of the cutter head 2. A plurality of chip removal ports 24 connected to the inside of the cutter head 2 are evenly opened along the circumference of the connecting portion 21 of the cutter head 2. In this embodiment, there are four notches 23 and four chip removal ports 24. The specific structure and working principle of the pneumatic punching knife are all prior art and will not be described in detail here. In this embodiment, the cutter head 2 is threadedly connected to the cutter seat 1.

[0027] The installation mechanism includes a mounting plate 3, a limiting plate 4 and a limiting block 5 fixed on the mounting plate 3, wherein the limiting block 5 is located in front of the limiting plate 4, a limiting groove 6 for the tool holder 1 to be embedded is provided on the limiting plate 4, a through hole for the cutter head 2 to pass through is provided on the limiting block 5, and a pressing plate 7 for limiting the tool holder 1 is fixed on the limiting plate 4. During specific installation, the tool holder 1 of the punching knife is embedded in the limiting groove 6 and fixed by the pressing plate 7, and the cutter head 2 passes through the through hole on the limiting block 5 and is exposed. The limiting plate 4 and the mounting plate 3, the limiting block 5 and the mounting plate 3, and the pressing plate 7 and the limiting plate 4 are all fixed by bolts.

[0028] The chip suction mechanism includes a chip suction port 8 provided on the limit block 5 and a negative pressure pneumatic system connected to the chip suction port 8 through an air pipe 9. The waste chips generated during the punching process enter the interior of the cutter head 2. After the negative pressure pneumatic system generates negative pressure, the waste chips are discharged through the chip discharge port 24 and sucked away through the chip suction port 8. During the entire punching process, the waste chips will not be scattered and accumulated everywhere, thus ensuring the environmental sanitation of the working area and the normal progress of the punching operation. There is no need for the staff to stop the machine to clean up the waste chips, thus improving work efficiency. The negative pressure pneumatic system includes a negative pressure fan. The specific structure and working principle of the negative pressure pneumatic system are prior art and will not be described in detail here.

[0029] In this embodiment, there are two sets of punching mechanisms, two limit slots 6, and two through holes are set on the limit block 5. The two sets of punching mechanisms are used to punch holes simultaneously, so that two holes can be punched on the drip irrigation pipe at the same time, thereby improving work efficiency.

[0030] During the specific operation, the position where the drip irrigation pipe needs to be punched is punched by the cutter head 2 of the pneumatic punching knife. The waste chips generated during the punching process enter the cutter head 2. Under the action of the negative pressure pneumatic system, the waste chips are discharged through the chip discharge port 24 and sucked away through the chip suction port 8. During the whole process of punching, the waste chips will not be scattered and accumulated everywhere, which ensures the environmental sanitation of the working area, avoids the accumulation of waste chips affecting the punching operation, ensures the normal progress of the punching operation, and does not require the staff to stop the machine to clean up the waste chips, thereby improving the work efficiency and reducing the labor intensity of the staff.
