Irrigation hose kubikova n. e.
(57) Abstract:Usage: agriculture for manual irrigation of fruit, vegetable and other crops. The inventive irrigation hose made in the form of a flexible high pressure tube 1 up to 20 m and more, end hole which tightly closed, and starting from a distance of 1-3 (or more) of diameter from its end in the side walls made of several rows of holes 3 with their chess accommodation or along a helical line so that the sum of the flow area was greater than the flow area of the tube 1, and at a distance of 2-10 cm from the most remote from an end of the tube 1 of the 3 holes (holes) fixed clamping device is a thin-walled casing 5 made of elastic material in the form of a cylinder or extending to the end of a truncated cone, the length of 2-5 times greater than the length of the end of the tube 1 with the side holes 3. 3 Il. The invention relates to agriculture and can be used for manual irrigation of fruit, vegetables and other crops in their gardens.Known horticultural irrigation hose for manual watering, are produced, in particular, industry rubber products, which includes about which which the receiver is connected with the choke valve of the water pipe and the water outlet, when this tube has the same vodoprovodnoi section, 10-20 mm and more, the entire length of the (Equivalent).This irrigation hose has a very significant shortcomings. Connecting it to the fitting of the valve (valve) high-pressure pipe, not the valve to open fully, as coming out of the end of the hose under high pressure and high flow rate of water is large striking force to wash away the soil, destroy its structure, to turn into a powdered state. Dust particles of soil will fill the space between the intact particles, degrade air mode, the root system is irrigated plants, and this, together with the environmental damage, and reduce the yield. However, the incomplete opening of the valve is artificial performance hose and labor foreman, increasing costs and the cost of their crops.Known irrigation hose: Discharge for overhead irrigation machines" from A. S. N 334954 by MCI A 01 G 25/00, B 05, 9/02 (bull. N 13 from 11.04.1972, by the same author Kubikova N. E. The prototype).And this hose-discharge has significant drawbacks, which lies in the fact that in his initial vodovypuske part has a nozzle-glass with relatively small compared to vypusk has artificially limited metering characteristic and low productivity, this hose can work virtually non-pressure and only in a vertically suspended position, otherwise it will be after the water from the side aerialway holes of the nozzle in the cylinder and hose.The purpose of the invention increase the productivity of irrigation, along with the reduction process of erosion by water fertility of irrigated land, improving water-air regime of the root system of plants, which increases the yield of crops. For this tube irrigation hose retains essentially without changing its flow cross-section throughout the length and integrity of the walls up to its end, at which end the tube tightly closed, and starting from a distance of more than one tube diameter from its end, in its side walls made of several rows of diametrically-opposite holes with their chess accommodation or helix, so that the sum of the flow area was larger bore tube, and at a distance of 2-10 cm from the most remote from the end cone of the tube holes, on the outer surface of the fixed clamping device is a thin-walled casing of elastic material (reclamation fabric, rubber, plastic film, etc.,) in the form of a cylinder or EXT and this vodoprovodnoi section of casing more than the sum of the flow area of all of the side water outlet holes in the walls of the tube.In Fig. 1 shows a longitudinal section of the proposed irrigation hose in its horizontal position; Fig. 2 is a process flow diagram of the operation of Fig. 3, along a-a of Fig. 2.The choke valve mounted on the water pipe irrigation network (Fig. not depicted) connected to its vodovypuske (initial) bore flexible high pressure tube 1 connected to port 2 of which end is tightly closed and at a distance of more than one tube diameter DT from its end in its side walls made of several rows of diametrically-opposite holes 3, with their chess accommodation or along a helical line, and at any distance in the range of 3-10 cm from the end holes (holes) 3(a) on the outer surface of the tube 1 is fixed clamping device 4 thin-walled casing 5 made of elastic material in the form of a cylinder or truncated cone, extending to the outlet end, a length lto2-5 times the length ltthe end of the tube 1 with the holes 3. While the total vodoprovodnoi section 3 holes exceeds the cross section of the tube 1, and the flow area of the casing is above the excess of the cross-sections of the holes 3 in comparison with the hole cross-section of the tube 1, and bore casing 5 the sum of the cross sections of the side holes 3 in the tube 1, the better the quality of the dampening water head facing the ground, but will need some more material to cover.It is quite possible and, apparently, even appropriate, making the end portion of the irrigation hose at the factory producing the tube 1 by a separate node: as consoles-absorber pressure irrigation water. This would require only one more detail: the connecting tube 6, which is better to connect the tube 1 and the outer surface, without reducing its diameter DT and productivity of irrigation.Coming from the network under a certain pressure in the tube 1 water, under less pressure, many jets out of the holes 3 in its end in radial directions, collides with the wall of the casing 5, which is essentially gravity-gravity is poured out upon irrigated the field surface in the form of a tape 7.When transferring irrigation hose to a new place, the valve is not shut down, as the water from the housing, with a low hold its end above the ground, will not destroy the soil and even harm the fragile young plants. In addition, the migration of a running hose even when a strong wind will not soaked irrigators (and e is th hose allowing you to achieve a higher efficiency irrigation, less soil erosion and greater productivity is of great interest for millions of owners of gardens, orchards, farms, and state that it is important to protect the land from erosion. Irrigation hose, comprising a flexible tube with inlet and outlet holes in the tip part, made deaf, and total reduced cross-section, a large diameter tube, and a casing in which is housed the end of the tube with the holes having an open end to release the water, characterized in that the holes in the end portion of the tube are arranged in rows and diametrically opposite in a checkerboard pattern or a spiral line, and the casing is secured to the tube at a distance of 2 to 10 cm from the past, counting from the end of the tube, holes, made of elastic material and has a length, 2 5 times the length of the end portion of the tube, in which the outlet.
