In order to enable the drip irrigation pipe perforating device to be suitable for perforating drip irrigation pipe strips with different inner diameter sizes, as a further improvement scheme of the drip irrigation pipe perforating device, a perforating needle 73 is fixedly arranged in a perforating needle mounting blind hole 75 through a depth adjusting mechanism I, the depth adjusting mechanism I can be a threaded connecting structure which is arranged between the perforating needle mounting blind hole 75 and the perforating needle 73 in a matched mode, or a plurality of positioning clamping grooves, positioning clamping spring structures and other depth adjusting structures which are arranged in the perforating needle mounting blind hole 75 along the depth direction of the perforating needle mounting blind hole 75 according to different extending length positions of the perforating needle 73; the connecting rod 78 is connected with the elastic telescopic component 77 through a depth adjusting mechanism II, and the depth adjusting mechanism II can be a threaded connection structure which is arranged between the connecting rod 78 and the telescopic guard plate telescopic control blind hole 76 in a matched mode, or other depth adjusting structures such as a positioning hole and a positioning pin structure which are arranged between the connecting rod 78 and the telescopic guard plate telescopic control blind hole 76 in a matched mode. The extension length of the perforating needle 73 can be adjusted by adjusting the depth adjusting mechanism I and the depth adjusting mechanism II, and the needle point of the perforating needle 73 is ensured to be positioned in the through hole of the telescopic guard plate 74.

In order to prevent magnetic field interference, as a further improvement of the present invention, the telescopic guard plate 74, the elastic telescopic member 77, and the connecting rod 78 are made of non-magnetic materials such as copper, aluminum, rubber, etc.

The perforating device for the drip irrigation pipe belt is provided with an electromagnetic positioning part comprising an upper electromagnet 1, a lower electromagnet 2, a left electromagnet 3, a right electromagnet 4, a front annular electromagnet 5 and a rear annular electromagnet 6 and a permanent magnet perforating operation part comprising a permanent magnet column 7, wherein the upper electromagnet 1, the lower electromagnet 2, the left electromagnet 3 and the right electromagnet 4 jointly form a permanent magnet column accommodating space, and the permanent magnet column 7 of a perforating mechanism comprising a mechanical structure is arranged in the permanent magnet column accommodating space, so that the permanent magnet column 7 can be accurately suspended and positioned in the permanent magnet column accommodating space by controlling the magnetic field direction of the electromagnetic positioning part, the drip irrigation pipe belt is sleeved on the permanent magnet column 7, the permanent magnet column 7 can move up and down by changing the magnetic field direction of the electromagnetic positioning part, and the perforating mechanism of the permanent magnet column 7 can perforate the drip irrigation pipe belt from the inside of the drip irrigation pipe belt to the outside of the drip irrigation pipe belt, not only can realize the firm shaping of apopore under shortening the debugging cycle, reducing extravagant prerequisite, can realize moreover that the edge-sticking burr that the in-process that punches produced is located the outside of pipe wall, and then reduces the phenomenon that the apopore blockked up in the drip irrigation pipe area use.
