Description

Technical Field

[0001] The utility model relates to the field of drip irrigation belts, in particular to a water-saving drip irrigation belt. Background Art

[0002] Drip irrigation is a precise irrigation method that uses a low-pressure pipe system to transport water directly to the field. The water is then dripped evenly and slowly into the soil near the root zone of the crop through emitters, orifices or drip tapes installed on capillary tubes. This allows the soil in the area where the crop root system is most developed to always maintain an appropriate humidity, and the soil's water, fertilizer, air, heat, and microbial activity are always in good condition, creating favorable conditions for high and stable crop yields.

[0003] When the current nozzle belt is laid in the field, the pipe body bulges into a cylindrical shape due to the water pressure, and it is easy to roll over in the field, causing the nozzle position to shift. In order to avoid the shift, a double-wing drip irrigation belt is introduced; but the double-wing drip irrigation belt may still shift in windy weather and other conditions, resulting in waste of drip irrigation water to the correct position; at the same time, the drip irrigation hole is easily blocked after a period of use due to the long-term direct contact of the drip irrigation belt with the soil, and the existing drip irrigation belt does not have an anti-blocking function when in use, and is easily blocked by impurities in the water flow, thereby reducing the drip irrigation efficiency.

[0006] Preferably, the impurity collecting assembly includes an upper semicircular block rotatably sleeved in the annular groove and located at the top and bottom of the connecting pipe for positioning and a lower semicircular block for collecting impurities, two impurity collecting grooves arranged on both sides of the lower semicircular block, two cleaning ports respectively arranged on the lower semicircular block and located at the bottom of the two impurity collecting grooves, two sealing plates slidably arranged on the two cleaning ports, two positioning holes arranged on both sides of one side of the upper semicircular block, a fixing block arranged on the top surface of the connecting pipe, a positioning pin with one end horizontally penetrating the fixing block and facing the side of the upper semicircular block with two positioning holes, a limit block arranged on the other end of the positioning pin, and a tension spring sleeved on the positioning pin and located between the limit block and the fixing block; the upper semicircular block and the lower semicircular block are fixed by bolt connection.

[0007] Preferably, the supporting and diverting assembly includes two guide plates respectively arranged on both sides of the drip irrigation belt body in the length direction for diverting irrigation water and preventing the soil below from clogging the water outlet holes on the drip irrigation belt body, four T-shaped slide grooves respectively arranged at both ends of the two guide plates, and four supporting legs respectively slidably arranged on the four T-shaped slide grooves for inserting soil.
