Abstract
The utility model relates to a novel drip irrigation belt which belongs to the field of hydraulic engineering, particularly a drip irrigator with the advantages of high efficiency, energy saving and water saving for the water saving irrigation for agriculture. The utility model is characterized in that a pipe-shaped object with certain length and certain diameter is formed into a water delivery passage. Pipe walls of both corresponding sides of an inner cavity of a pipe utilizes the physical or chemical method to be tightly combined together to form a discontinuous long and thin strip by means of one personal part of the pipe. One end of the long and thin strip is not connected with an outer wall of the pipe to form a water inlet passage, and the other end of the long and thin strip is connected with the outer wall of the pipe to form an auxiliary closed flow passage. The closed end of the auxiliary flow passage is drilled with a thin hole to form a water outlet passage. Water with the definite pressure passes through the water inlet passage to enter the auxiliary flow passage, and flows out of the thin hole at the closed end of the auxiliary flow passage to complete the irrigation for crops. The utility model has the advantages that the complicated manufacturing technique is removed, the materials are saved and the manufacturing cost is reduced.
Description
Technical field new drip tape of the present utility model belongs to the water conservancy project field, relates in particular to efficient, the energy-saving drip emitter of irrigating crops in the agricultural water-saving irrigation.
Background technology water is the necessary condition of agricultural development, and the problem of lack of water has become the bottleneck of restriction World Economics sustainable development.In China, this problem is especially outstanding, advocates and implement agricultural water-saving irrigation energetically, improving the ecological environment becomes the fundamental state policy of China.The runner of labyrinth type drip irrigation tape commonly used mainly adopts the technology of negative pressure plastic uptake to form at present, exists manufacture process requirement very high, the defective that the runner deviation is bigger; In addition, the wall ratio tube wall of the runner that the negative pressure plastic uptake forms will approach, and when pressure changes when raising, the tube wall of runner will explosion, and scrap the irrigate band.New drip tape overcomes above deficiency, and irrigation uniformity is reached more than 95%, makes production cost reduce by 30% simultaneously.
Summary of the invention the utility model is to overcome existing irrigate band manufacturing technique requirent height, the runner deviation is big and use the wall ratio tube wall of the runner of negative pressure plastic uptake formation to approach, the defective of explosion easily takes place, irrigation uniformity is reached more than 95%, reducing production costs simultaneously reaches 30%.
The utility model is achieved in that this new drip tape forms water transport channel by the tube of certain-length and diameter, utilize the method for physics or chemistry to be closely linked at a part of tube wall of the corresponding two side tubes of the inner chamber of pipe self and form discontinuous elongate strip, one end of elongate strip does not link to each other with the outer wall of pipe, form intake tunnel, the other end of elongate strip joins with the outer wall of pipe, form the secondary channels of sealing, be equipped with pore, form aquaporin at the blind end of secondary channels.The water that has certain pressure enters secondary channels by intake tunnel, and the pore by the secondary channels blind end flows out again, finishes the irrigation to crop.
