[0016] The embodiment of the utility model provides a double-wing labyrinth-type drip irrigation belt forming wheel.

[0017] See also Figure 1 The double-wing labyrinth drip irrigation belt forming wheel includes a main shaft 11, which is characterized in that: a forming wheel 1 is provided on the main shaft 11, and a plurality of circumferential array labyrinth forming parts are provided on the forming wheel 1, and the labyrinth forming part includes a first serrated negative pressure forming groove 2, a first channel 3, a second channel 4, a first water outlet negative pressure groove 5, a second water outlet negative pressure groove 6, a second serrated negative pressure forming groove 7, a water inlet negative pressure groove 8 and a connecting groove 9, and the second water outlet negative pressure groove 6 is connected to one end of the first serrated negative pressure forming groove 2. The first serrated negative pressure forming groove 2 is connected to the first channel 3 through the connecting groove 9, and the number of the connecting grooves 9 is three to five. The first channel 3 and the second channel 4 are connected through the first water outlet negative pressure groove 5, the second channel 4 is connected to the second serrated negative pressure forming groove 7, and the water inlet negative pressure groove 8 is connected to the second serrated negative pressure forming groove 7. The number of the water inlet negative pressure grooves 8 is five to eight. Vacuum suction holes are provided inside the first serrated negative pressure forming groove 2 and the second serrated negative pressure forming groove 7.

[0018] Working principle: When making a double-wing labyrinth drip irrigation belt, the blow-molded drip irrigation belt tube bubble is located at the contact point between the molding wheel 1 and the pressure wheel. The drip irrigation belt tube bubble is pressed by the relative rotation of the molding wheel and the pressure wheel. The first serrated negative pressure molding groove 2 and the second serrated negative pressure molding groove 7 of the negative pressure molding groove of the molding wheel 1 are provided with vacuum suction holes. The vacuum pump draws air through the vacuum suction holes to generate negative pressure on the wheel surface of the molding wheel 1. The drip irrigation belt tube bubble near the contact point between the pressure wheel and the molding wheel 1 is adsorbed on the wheel surface of the molding wheel 1 due to the negative pressure. The drip irrigation belt tube bubble close to the wheel surface of the molding wheel 1 is sucked out of the shape of the labyrinth molding part. The dripping amount of the double-wing labyrinth drip irrigation belt is correspondingly increased compared with the single-wing labyrinth drip irrigation belt, thereby increasing the soil moisture.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
