Sprinkler

FIELD: agriculture.

SUBSTANCE: sprinkler includes a cylindrical body and a lid. The cylindrical body comprises slotted turnouts in the middle part. In the lid opening a finely divided spray is set. Annular grooves are made on the inner surface of the body, above and below the slotted turnouts. In the annular grooves O-rings are placed. The lid of the sprinkler has a ring bearing collar. The annular bearing shoulder comes up inside the body to the upper ring groove. In the lower part of the body a mechanism of switching modes of operation of the sprinkler is placed. The mechanism of switching modes of operation of a sprinkler consists of locking drum commensurate with the inner diameter of the body with O-rings coming into the grooves. At the bottom of the locking drum holes are made. In the center of the locking drum a lead-trough tube is mounted with a spring mounted on it. The spring passes through the hole in the lid to its outer surface. The finely divided spray consists of a deflector with a calibrated channel and the sparger of the stream with a spiral groove on the surface. The deflector with a calibrated groove is fixed by screwed connection in the upper part of the tube of the locking drum at the exit of the body. The sparger of the stream with a spiral groove on the surface has a diameter of the deflector channel, and installed with a bracket on the body lid at the exit of the deflector coaxially with it.

The present invention relates to agriculture and can be used for irrigation of small plots of land, mostly garden.

A known design of sprinkler producing irrigation sector, including rack, inlet hose and crevice nozzle (U.S. Pat. Of the Russian Federation No. 2069106, WV 1/06, IB No. 32 of 1996).

The disadvantage of this design is her limitations, as it has a permanent irrigation sector and may not work in the mode of fine sprinkling.

The closest in technical essence is the design of the sprinkler, providing the possibility of changing the sector sprinkling and switching it to work in the mode of fine sprinkling (U.S. Pat. Of the Russian Federation No. 2365097, A01G 25/02, BI No. 24 of 2009).

The disadvantage of this design is the lack of a mechanism to flush fine spray and manual switching of each sprinkler with strip irrigation on fine.

The purpose of the present invention to mechanize the operation mode switching of the sprinkler and rinse fine spray.

This goal is achieved by the fact that in a sprinkler, comprising a cylindrical housing with a slotted outlets in the middle part and the cover in the hole which installed fine spray, according to the invention on the inner surface the body, the top and bottom of slab culverts, made circular grooves placed in them o-rings, cover sprinkler has an annular abutment shoulder, reaching inside to the upper annular groove, and in the lower part of the body, there is a mechanism for switching modes of operation of the sprinkler, consisting of shut-off drum, commensurate with the inner diameter of the casing with its grooves with o-rings in the bottom of which holes, and center-mounted end-to-end tube with installed spring through a hole in the lid to its outer surface, and a fine spray consists of a baffle with a calibrated channel, fixed screw the connection at the top of the tube shut-off of the drum at the outlet of the housing, and divider jet with a spiral groove on the surface having a channel diameter of the baffle and installed using a bracket on the housing cover at the exit of the deflector coaxially him.

The proposed design unlike closest allows switching mode bandpass sprinkling on the mode of sprinkling change in working pressure in the body of the sprinkler and to make washing fine spray at each change of mode of operation.

The essence of the proposal p is explained by the drawing, which figure 1 presents a view of the sprinkler in the context when working in mode bandpass sprinkling, as in figure 2. - type of sprinkler in the context when working in the mode of fine sprinkling.

The sprinkler consists of a cylindrical body 1, in the middle part of which are slotted outlets 2, top and bottom are circular grooves 3 with elastic sealing rings 4. The top of the casing is closed by a cover 5, a part of the inside of the case support collar 6 to the top ring groove 3. On the surface of the cover 5 on the bracket 7 has a divider 8, provided with a spiral groove 9. The divider 8 is coaxially calibrated channel deflector 10, the paired through the opening 11 in the cover 5 through the tube 12, which is worn spiral spring 13. The outer diameter of the divider 8 corresponds to the inner diameter of the calibrated channel deflector 10. The upper end of the tube 12 is mated with a deflector 10 with a thread 21 made in the upper part of the tube 12 and the outside of the baffle 10. The lower end of the tube 12 is rigidly connected to the bottom 14 of the drum 15 of the switching mechanism operating modes. In the bottom 14 holes 16, providing for the passage of water in the upper part of the housing 1. Threaded coupling 21 of the deflector 10 with the tube 12 allows for installation of drip lock spring 13 in a predetermined laid the I. In the lower part 17 of the housing 1 of the sprinkler made pipe 18 which is connected to the power hose 19. To accommodate the sprinkler on irrigated land is attached to the hull bottom of the strut 20.

The operation of the sprinkler can be performed in two modes: in mode bandpass sprinkling of soil for a given irrigation sector and in the fine mode of the humidification of the air and surface of leaves in the canopy of a tree.

When the sprinkler mode bandpass sprinkling (figure 1) drum 15 is in a predetermined lower position, in which the slotted outlets 2 are fully open. Irrigation water under a pressure of 0.1 MPa in the inlet hose 19 through pipe 18 enters the lower part of the housing 1 and, flowing through the openings 16 in the bottom 14 of the drum, enters the upper part of the housing and flows in the form of rain and streams from slot 2 culverts on the surface of the irrigated strip. At the same time part of the flow passes through the cavity of the tube 12 and the calibrated channel deflector 10 to the divider 8, the formation of raindrops, moistening the soil directly around the sprinkler.

To switch the sprinkler mode fine sprinkling working pressure increased to 0.2 MPa, under which the drum 15 is moved up against the support flange 6 and interacting with seal is ranked on the rings 4, completely covers the slot 2 culverts. The tube 12 is moved upward together with the drum 15, push deflector 10 to the divider 8. The outer diameter of the divider 8 corresponds to the diameter of the channel deflector 10, and therefore overlaps the channel of the deflector. Water is directed in a spiral groove 9 made on the surface of the divider 8, and out of the torch drops the size of 50-100 μm. The abutment flange 6 not only limits the pressure on the spring 13, but also provides the same length of helical grooves 9 in all of the sprinklers on the irrigation pipeline and, accordingly, the same water flow.

Upon completion of the sprinkler mode fine sprinkling of the working pressure in the network reduces. When the drum 15 under the action of the spring 13 moves downward, removing the deflector 10 from the divider 8. The stream of water, dripping from the vent and washing the surface of the divider 8, washes the groove 9 from possible impurities.

Thus, the proposed design of the sprinkler allows to mechanize switching operating modes and to produce washing fine spray, by doing this simultaneously on all the sprinklers irrigation network.

A sprinkler, comprising a cylindrical housing with a slotted outlets in the middle part and the cover in the hole which has melodisi sny spray, characterized in that on the inner surface of the housing, the top and bottom of slab culverts, made circular grooves placed in them o-rings, cover sprinkler has an annular abutment shoulder, reaching inside to the upper annular groove, and in the lower part of the body, there is a mechanism for switching modes of operation of the sprinkler, consisting of shut-off drum, commensurate with the inner diameter of the casing with its grooves with o-rings in the bottom of which holes, and center-mounted end-to-end tube with installed spring through a hole in the lid to its outer surface, and a fine spray consists of a baffle with a calibrated channel, fixed threaded connection at the top of the tube shut-off of the drum at the outlet of the housing, and divider jet with a spiral groove on the surface having a channel diameter of the baffle and installed using a bracket on the housing cover at the exit of the deflector coaxially him.
