Device for watering
(57) Abstract:Usage: for watering rows of vegetable crops. The inventive device consists of several series-connected sections long trays with compartments, above whom there is a tube with holes for uniform simultaneous water flow along the entire length of the ridge. 2 C. p. F.-ly, 2 Il. The invention relates to vegetable production, in particular to devices for watering rows of vegetable crops in the suburban and rural sites.The device can be used for irrigation of vineyards and garden shrubs in commercial plantations.A device for watering garden plants, containing the tool to accommodate the water supply hose (Patent USSR N 1716944, CL 01 And G 25/02, 1990).However, using this device irrigation on vegetable plot is inefficient, blurred acciaierie rolls, exposed plant roots, unevenly impregnated soil depth on the length of the patch.The purpose of the invention increase the efficiency of irrigation increases the yield of vegetables by providing the possibility of eliminating the water erosion of the soil by watering minichannel volcolm long narrow trays, each of which is divided into compartments impermeable bulkhead height exceeding the height of the trays. Over the trays are tubes with holes according to the number of compartments. Tubing installed annular valve regulating the flow of water evenly over the entire length of the device. Baths are connected with one another along the length of the bed with fittings. Mechanical hole in the last tube is plugged with a stopper. The device is connected to the water supply hose that is magnetorheological magnetic induction in the area of magnetised about 0.1 Tesla.In Fig. 1 shows a device for watering, top view; Fig.2 section a-a in Fig.1.Device for irrigation contains a long narrow tray 1 with compartments separated by bulkheads 2, top baths are tube 3 with the holes that have annular valve 4.The sections are interconnected by pipes 5, the socket hole in the last tube is plugged with a stopper 6. To the water supply device is connected by a hose 7 installed magnetorheological 8.The principle of the device for Liwa following.The required number of trays 1 rasputeen 8 is connected to the water supply. The flow of water coming from the water, magnetivity and through the openings in the tube 3 enters the compartments of the trays and then poured evenly throughout the bed. For uniform water flow over the entire length of the bed adjusts annular valve 4. Within seconds the flower bed along the entire length filled with water, which is evenly absorbed into the soil to the desired depth together with fertilizers, not allowing them to fall into the groundwater.The number of sections may vary depending on the length of the beds.The efficiency of the device is as follows: increases the speed of irrigation; reduced water consumption by 1.5-2 times; evenly moistened the soil to the desired depth; eliminated irrigation soil erosion; reduced fertilizer consumption; excludes the possibility of closure of irrigation and groundwater, as well as swampness and soil salinization and flooding of low areas; increased productivity through the use of minichannel water for watering plants and full use of fertilizers. This is an opportunity to irrigate vegetable crops on terraces and uneven ground.The device tested in practice and gives positive results. 1. Ustroena fact, the body of the dispenser is made in the form of a number of serially interconnected pipes baths, over each of which is having apertures tube connected to the water supply hose.2. The device according to p. 1, wherein the tube is provided with an annular valves to control the cross-section of the holes.3. The device under item 1, characterized in that the tube connected to the water supply hose through magnetorheological.
