    A two-stage retractable sprinkler comprises a first-stage riser tube, with inner and outer walls forming an annular peripheral channel and with a first piston head at its open lower end guided in a stationary cylinder, and a second-stage riser tube with a second piston head at its closed lower end guided in the first-stage tube. The second piston head has a peripheral groove communicating with an axial bore of its tube through radial holes through which water entering the bottom of the guide cylinder can pass to an outlet at the top of the second-stage tube by way of a set of vertical slots, formed near the top of the inner wall of that tube, after both tubes have been elevated by the water pressure. The slots are sealed from without by a sleeve in the annular channel which has external flutes forming passages for the retraction of the second-stage tube under water pressure and for the escape of water from the closed top of the first-stage tube, via other radial holes in the inner and outer walls thereof, when the second-stage tube is extended.

    专利说明:

    The invention relates to agriculture and can be used on stationary sprinkler systems for watering high-stem agricultural crops. The well-known immersion sprinkler for tall crops, consisting of a stationary cylinder connected to the main and additional water supply networks, and two telescopically mounted steps in it, of which the lower two-stage and the upper one have a movable piston for remote control of the operation of the hydrant. The disadvantage of a plunging sprinkler for tall crops is the presence of axial holes in the pistons of both telescopic stages, through which, when removing racks above the earth's surface, water flows inefficiently and the lifting force of the pistons is reduced, and the presence of a movable piston with remote control in the upper stage, which it requires frequent position adjustment and reduces the reliability of the hydrant. A one-stage immersing hydrant with an axially dense piston is also known, the axial hole to which is connected to the annular groove n of the side surface of the piston by means of radial holes, and two levels are drilled in the vertical part of the cylinder. The well-known hydrant is its low clearance height of the rack above the ground and the presence of an outer annular chamber of the cylinder, which complicates its technical implementation. The aim of the invention is to create a telescopic submersible hydrant that would use the full lifting force of water pressure during a notch of a telescopically submerging rack, and the flow of water to the sprinkler would occur after the upper step was dredged above the ground without using an external annular chamber for this purpose. The goal is achieved by the creation of a telescopic submerging hydrant, in which in the upper part under the axial holes of the inner wall — the lower step of the stand, vertical slots are drilled, which are hermetically sealed on the outside by a sleeve placed between the two annular walls and the lower step and on the outer wall bushings made vertical channels, offset from the cracks in the inner wall of the lower-step. The length of the slots of the inner wall of the lower stage is greater than the length of the piston of the upper stage, calculated from the upper annular groove along the lateral surface of an axially dense piston at its lower end. -. . The distance from the upper end of the slots to the upper part of the inner wall of the lower stage is equal to the distance from the upper end of the annular groove along the lateral surface of the axially dense piston to the upper end of its limiters. The advantages of the invention are that a full lift of water pressure is used during the removal of the telescopic submersible stand, the water flowing to the sprinkler after the upper stage is excavated above the ground without using an external annular chamber. FIG. 1. shows a section along the axis of the telescopic submersible hydra-nta; in fig. 2 is a section A-A in FIG. A telescopic, immersed hydro-, rand with vertical slots 7 in the upper part, under the axial holes 9 of the inner wall 16 of the lower stage 6 of the rack. These slots 7 are hermetically sealed on the outside by a sleeve 8 placed between two annular walls 16 and 17 the lower stage 6, and vertical channels 15 are made on the outer wall of the sleeve 8, offset from the slots 7 on the inner wall 16 of the lower stage 6. The length of these slots 7 is longer than the length of the piston 12 of the upper stage 11, counting from the upper end of the annular kanesh 14 along b The circumferential surface of the axially dense piston 12 to its lower end, and the distance from the upper end of the slots 7 to the upper end of the inner wall 16 of the lower stage 6, is equal to the distance from the upper end of the annular groove 14 along the lateral surface of the dense one. the piston 12 to the upper end of its limiters, the action of the hydrant is as follows. When turned on, water enters through the main supply line 18 and through branch 19 into the sub piston space of the stationary cylinder 1 and begins to rise upward the bottom 6 and top 11 stages of the telescopic submersible stand. When the upper stage 11 reaches its upper position, the water passes through the slots 7 of the inner wall 16 of the lower stage 6 and through the annular groove 14 and the axial holes 13 passes to the hole for connecting the sprinkler. Water from the above-piston space of the two stages 6 and 11 flows out respectively through the axial holes 9, the vertical channels 15 of the bushings 8 and the axial holes 5 into the additional pipeline 4.
    When cleaning the telescopic submersible stand into the stationary cylinder 1, an additional pipeline 4 is turned on and water enters the piston 3 above the piston space of the lower stage 6, and through the axial
    the holes 5, the vertical channels 15 and the axial holes 9 are respectively in the piston space of the axially dense piston 12 of the upper stage 11,
    Both stages are removed respectively to the bottom of the stationary cylinder 1 and to the restrictive ring 2 of the lower stage 6, and water from the piston spaces of both stages is pushed through the outlet 19 into the main supply line 18.
