Dropper /Karpunin Centuries, Abasin Century, Caldew A. M., Sukhin A. I., D. A. N., Rakuten C. M. Stated 22.03.2001 published 27.01.2003, bull. No. 3). This drip adopted us for the nearest equivalent.The disadvantages of this design droppers are low reliability because of the possibility of clogging capreolata holes and uneven soil moisture at a depth of deteriorating irrigation.The invention consists in the following.The problem to which the invention is directed is the provision of intermittent portions of the water supply, improving the reliability and ensure uniform wetting of the soil depth.The technical result is a reliable batch water supply and uniform moistening of the soil depth.This technical result is achieved by the fact that in the known kapeliela and counterweight, moreover, the lower part of the housing is a hollow tapered injector, the walls of which are made across the lateral surface of the conical hole extending from the inner to the outer surface. Due to the reciprocating rotary movement of the locking element is provided rationed water supply to the injector, and the holes in the injector ensures uniform wetting of the soil depth.The invention is illustrated by the drawing, which shows a transverse vertical section of the declared dropper-dispenser Assembly when filling the metering cavity with water.Information confirming the possibility of implementing the claimed invention are as follows.Dropper-dispenser (see drawing) includes a housing 1, which when connected with the cover 2 is of a cylindrical cavity. In the cover provided for the inlet, the axis of which is offset in a lateral direction relative to a vertical cylindrical cavity.In the cylindrical cavity through the hub 4 on the shaft 5 with the possibility of free rotation is selected dispenser, which has a shut-off element 6 made in the form of a hollow segment, the blade 7 and the counterweight 8, made in the form of a monolithic segment. The side with the mustache 1 is provided with fastening elements 10. To limit the stroke of the blade 7 in the side surface of the case is made limiter 11. The housing 1 is made as a single piece with a hollow injector 12, which has on the whole side surface of the through conical holes 13. The diameter of the hole on the outer surface is greater than on the inside. At the end of the injector has a point 14. Using the taper 14 is provided by the introduction of the injector in the root layer of soil.Dropper-dispenser works as follows.Nipples irrigation pipe flexible sleeve connected to the inlet pipe 3 of the cover 2 droppers. In the initial position, the dispenser is in position, when the locking element 6 abuts against the stopper 9, which is provided by the effect of the counterweight 8. Water from the irrigation pipe by a flexible hose enters the inlet pipe 3 and fills the metering cavity formed by the wall of the locking element 6 and the blade 7. Once the cavity is filled with water, under the action of its weight, which is transmitted to the blade 7, overcome the force of the weight of the counterweight 8 and dispenser is rotated. When this shut-off element 6 closes the hole inlet pipe 3 and the flow of water stops.At the same time, the blade 7 moves the AET in the injector 12. When moving inside the injector 12, water flows into the holes 13 and due to their conical shape pushes trapped in their soil and evenly moistens the soil rooting depth soil layer. After emptying the metering cavity instead of 8, acting on the hub 4 of the dispenser, turn it. When this shut-off element 6 opens the inlet and the water from the hole inlet pipe fills the metering cavity. Thus, the dropper works automatically.The volume of the metering cavity may vary depending on the required performance of the dropper by moving the mounting of the locking element 6 and the blades 7 on the hub 4. Portions of the water supply to the injector enables better absorption of water in the soil, and the injector with conical holes evenly moistens the root layer of soil depth.
