Anti-freezing drip irrigation apparatus with drip irrigation nozzle cleaning function

Abstract

The invention relates to an anti-freezing drip irrigation apparatus with a drip irrigation nozzle cleaning function, which comprises a water tank, a first duct and at least two drip irrigation nozzles, as well as a water circulation mechanism and at least two dredging mechanisms. The water circulation mechanism comprises a second duct, a bypass pipe, a piston block, a cylinder and two one-way components; each dredging mechanism comprises a lifting ring, a wire mesh, a push bar, a spring, a first through hole and a power unit; each one-way component comprises a support plate, a cover plate, a second through hole and two slide bars; each power unit includes a fixing sleeve, a rotary shaft, a roller and a connection line. The water circulation mechanism in the anti-freezing drip irrigation apparatus enables a flow of water to cyclically run between the first duct and the water tank, so that chances for the flow of water to freeze are slimmed, and the anti-freezing drip irrigation apparatus is more practical; the drip irrigation nozzles can be dredged through the dredging mechanisms, so that chances for the drip irrigation nozzles to be blocked are slimmed, and drip irrigation effect of the anti-freezing drip irrigation apparatus is improved.

Description

technical field [0001] The invention relates to the field of water-saving irrigation equipment, in particular to an antifreeze drip irrigation device with a drip irrigation head cleaning function. Background technique [0002] Drip irrigation equipment uses plastic pipes to send water to the roots of crops through orifices or drippers on capillary tubes with a diameter of about 10mm for local irrigation. It is the most effective water-saving irrigation method in arid and water-deficient areas. Compared with sprinkler irrigation, drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to more than double the fertilizer efficiency. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for field crop irrigation in dry and water-deficient places. The disadvantage is that the dripper is easy to scale and block, so the water source should be strictly filtered. [0003] As a ...

Its disadvantage is that the dripper is easy to scale and block, so the water source should be strictly filtered

[0003] As a kind of irrigation equipment, drip irrigation equipment greatly reduces the waste of water resources in the irrigation process. When the drip irrigation equipment of the prior art is used in winter, due to the low temperature, the water inside the pipeline is prone to freezing, causing the pipeline to easily Not only that, but during the use of the drip irrigation equipment in the prior art, the drip irrigation head is prone to blockage due to the impurities in the water, which reduces the drip irrigation effect of the drip irrigation equipment.
