Abstract

The invention provides a pulling lifting type farmland irrigation water supply device, which mainly consists of a water inlet, a plug seat, a conical rubber plug, an inner pipe conical opening, an inner pipe, an outer pipe, a sealing groove press cover, a sealing ring, a water outlet, an operation handle and the like. During the irrigation, the water outlet extends to a position above the ground, the water outlet contracts to a position under the ground when being closed, the mechanical cultivation and harvesting cannot be influenced, the water outlet is aligned with irrigation targets in any directions, and the carrying of a switch handle is not needed.

Description

Pull elevation (over-and-under) type land irrigation water feeding device

Affiliated technical field

The present invention relates to have in the pipe-line system device to pipeline conveying fluid or field water channel water supply of control, especially relate to the field irrigation hydrant.

Background technology

At present, known field irrigation hydrant is installed in more than the ground, mainly is comprised of vertical tube, key, valve, switch handle etc., planform is similar to fire hydrant, during irrigation, with switch handle changeover valve switch, current flow out from pipeline valve, irrigate.There are three defectives in known field irrigation hydrant, the one, because hydrant is above ground level larger, agricultural tilling and seeding machine tool is in order to hide hydrant, need the larger radius that detours of hiding, can not get cultivating near causing hydrant, harvesting season, the crops is dense, grain header often breaks hydrant, causes irrigation conduit to damage and leaks, and can't use; The 2nd, the delivery port direction is fixed, and can not freely rotate by 360 degree; The 3rd, must carry the valve switch handle when irrigating, cumbersome.

Summary of the invention

In order to overcome the deficiency of known field irrigation hydrant, the invention provides the operation of need not detouring of a kind of agriculture tilling and seeding machine tool, harvesting machinery does not clash into the damage waterworks, hidden underground when not irrigating, be raised to during irrigation more than the ground, need not carry the irrigation waterworks that switch handle rotarily opens valve.

The technical solution adopted for the present invention to solve the technical problems is: waterworks are comprised of water inlet, obturating plug, cone rubber plug, inner tube cone mouth, inner tube, outer tube, sealing ring, seal groove gland, delivery port, operating handle etc., inner tube can move up and down in outer tube, realizes the unlatching of convection cell or the control of cut-out by inner tube cone mouth and cone rubber plug.The push handle, inner tube moves down, and the cone rubber plug is inserted in the inner tube bell, so that waterworks are in closed condition, water outlet is in below ground at this moment, and in order to guarantee to close sealing effectiveness, the taper angle of inner tube bell is less than the taper angle of cone rubber plug.During irrigation, upper pulling process handle moves on the inner tube, and delivery port rises to more than the ground, and inner tube bell and cone rubber plug break away from, and current flow into inner tube through water inlet, is flowed out by delivery port, and delivery port can be aimed at the irrigation target of any direction, finishes opening process.

The invention has the beneficial effects as follows, delivery port is elongated to more than the ground during irrigation, closes and is reduced at present below ground, does not affect mechanization and cultivates and gather in, and delivery port is aimed at the irrigation target of any direction, need not carry switch handle.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples, and Fig. 1 is principle of the invention figure.

1. water inlets among the figure, 2. obturating plug, 3. cone rubber plug, 4. inner tube cone mouth, 5. inner tube, 6. outer tube, 7. sealing ring, 8. seal groove gland, 9. delivery port, 10. operating handle.

Embodiment

In Fig. 1, open the waterworks process: upwards promote switch handle (10), inner tube (5) moves upward, until delivery port (9) reaches more than the ground, inner tube bell (4) breaks away from rubber conical plug (3), current enter inner tube (5) by water inlet (1), flow out through delivery port (9).

Close the waterworks process: downward push switch handle (10), inner tube (5) moves downward, until cone rubber plug (3) is inserted in the inner tube bell (4), current can't be flowed in the inner tube (5) by water inlet (1), waterworks are closed, sealing ring (7) is between inner tube (5) and the outer tube (6), is covered by seal groove gland (8), avoids water body by oozing out between inner tube (5) and the outer tube (6).

Claims

1. pull elevation (over-and-under) type land irrigation water feeding device, mainly consisted of by water inlet, obturating plug, cone rubber plug, inner tube cone mouth, inner tube, outer tube, sealing ring, seal groove gland, delivery port, operating handle etc., it is characterized in that: realize the unlatching of convection cell or the control of cut-out by inner tube cone mouth and cone rubber plug.

2. pull elevation (over-and-under) type land irrigation water feeding device according to claim 1, it is characterized in that: the taper angle of inner tube bell is less than the taper angle of cone rubber plug.

3. pull elevation (over-and-under) type land irrigation water feeding device according to claim 1, it is characterized in that: inner tube can move up and down in outer tube.
