Abstract

The utility model relates to a drip irrigation pipe for irrigation, which is especially suitable for irrigation in a plastic tunnel. The utility model is composed of a dripper core and a hair pipe, wherein, both sides of a partition board on the middle part of a dripper core body are provided with an integrally connected hair pipe joint, a side groove is arranged on the partition board, and the side groove and an end head of a water inflow hair pipe form a drip hole. An inner flow passage is formed between an inner wall of the water inflow hair pipe and the hair pipe joint with an outer screw thread of the dripper core. The utility model has the advantages of simple structure, convenient installation, convenient use, convenient maintenance, good drip irrigation effect, low cost and long service life.

Description

Irrigate the drip irrigation pipe of usefulness

The utility model relates to a kind of drip irrigation pipe of irrigating usefulness, is particularly suitable for the usefulness of irrigating in plastic tunnel.

Along with the penetration and promotion of plant husbandry in science and technology development and the plastic tunnel, the irrigation problem to plant in its canopy is crucial, also is that plant growth institute is necessary.Because of in the canopy to the protective effect of moisture content; the outdoor relatively land for growing field crops of institute's water requirement will be lacked; adopt drip irrigation pipe or irrigate band to irrigate so irrigate in many canopies; its drip irrigation pipe is to tumble in the water dropper core in discontinuously in Ф 6～Ф 16 vinyl tubes; and correspondence position perforate on tube wall, to form irrigator.The production equipment costliness of this product, cost height, the water dropper core is wrapped in polyethylene pipe inside fully, and the fluidised form of water mostly is a turbulent in the pipeline, and uniformity of irrigation water appilcation is subjected to water dropper core energy dissipating mode to influence bigger, blockage problem cannot solve, and should not use as the underground drip irrigation pipe.Maintenance cost height when problem such as fracture, pin hole is arranged when drip irrigation pipe, pipe is harder, self and supporting cost height during the greenhouse utilization; And existing irrigate band bearing capacity is low, weeper can't be handled after stopping up, service life is shorter, the fluidised form of water mostly is a turbulent in the pipeline, uniformity of irrigation water appilcation is subjected to merchant's energy dissipating mode to influence bigger, the irrigate band is easily broken, easily broken and processing cost is high, can not use as underground drip irrigation tubing, with its auxiliary products cost height, installation trouble, be difficult to apply.

The purpose of this utility model provides a kind of drip irrigation pipe of novel irrigation usefulness, can solve the drip irrigation pipe problem that drip irrigation is used effectively.

The purpose of this utility model is achieved like this, threading, water outlet hollow billet on water dropper core two ends, the water dropper core is on the dividing plate both sides at core body middle part male connection and the hangnail joint that is connected as one to be arranged, on the dividing plate periphery of male connection one side side channel is arranged, between side channel and water inlet pipe termination weeper is arranged, constitute inner flow passage between the external screw thread of water inlet pipe inwall and water dropper core.

The utility model novel structure, simple, installation, use, easy to maintenance, irrigation effect is good, and cost is low, is easy to penetration and promotion and uses.Good economic and social benefit is arranged.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is the utility model structural profile front view.

Fig. 2 is an A-A section right side view among Fig. 1.

Provide by Fig. 1, the utility model is to be made of water dropper core and water-in and water-out hollow billet, there is external screw thread hollow billet joint 7 and the glochid pipe joint 4 that is connected as one on dividing plate 5 both sides at water dropper core body 3 middle parts, into water hollow billet 1 is housed on the external screw thread hollow billet joint 7, water outlet hollow billet 2 is housed on the glochid pipe joint 4, side channel 6 is arranged on the periphery of dividing plate 5, side channel 6 constitutes weeper 8 with water inlet hollow billet 1 termination, 7 of the external screw thread hollow billet joints of water inlet hollow billet 1 inwall and water dropper core constitute inner flow passage 9, the water-in and water-out hollow billet is connected with the endoporus 10 of water dropper core, constitutes the flowing water passage.

The utility model advances, the water outlet hollow billet is a plastic flexible pipe, it in use is the polyethylene plastic hose that adopts Ф 4-Ф 8, its sanction is cut into the length of the dripper spacing of setting, its head and the tail are carried out connected with Ф 4-Ф 8 water dropper cores respectively to be connected, form formula drip irrigation pipe between pipe, therefore water inlet pipe and outlet pipe are comparatively speaking, for example at the outlet pipe of last joint after linking to each other with next joint, be water inlet pipe, therefore, its water dropper core two joints can be identical, also can be different, but its effect is the same, does not have essential distinction on the structure, is adopt inequality among the present embodiment figure, promptly an end is a nipple, the other end is the joint that has hangnail, side channel on the dividing plate 56 at least one, can be a plurality of in case of necessity or on the two sides, offer.During drip irrigation, water is entered by the water inlet hollow billet, because the permeability of water, water then flow to side channel through inner flow passage, and outwards oozes from weeper, realizes the purpose of drip irrigation.

By above-mentioned situation as can be seen, the utility model is compared with existing drip irrigation pipe (band), has obvious superiority: under condition of work, become laminar flow regime in the drip irrigation pipe very soon because of the thin current of caliber enter, pour water evenly; For ease of maintenaince, after drip irrigation pipe generation blockage problem without instrument, do not spend and can get rid of; Green house application and supporting cost are low, and simple; Production equipment is simple, cost is low; Life-span is long, pressure-bearing is high, anti-acupuncture.It applies well received.
