Description

Angle watering system

Technical field

The present invention relates to a kind of center whirling irrigation system, it can align the corner position in the place of irrigating and irrigate.More specifically say, the present invention relates to a kind of improved, can control and come from the device that corner is striden the water distribution of arm.

Background technology

Conventional center whirling irrigation system comprises a microscler girder, and this girder end place within it is rotatably connected on the center rotational structure, and outwards stretches thus.The girder of conventional center whirling irrigation system is made up of a plurality of pipe fittings that link together in the headtotail mode, and pipe fitting then is supported on a plurality of driving pylons.In the whirling irrigation system of the center of most conventional, the driving pylon of distal-most end is the king-tower frame, and other pylon then drives selectively according to the angle displacement situation of contiguous girder part.

In phase early 1970s, developed some and be used for the corner system of center whirling irrigation system, so that the corner position in square place obtains irrigating.This for example can consult United States Patent (USP) 3,797,517; 3,802,726; 3,902,668.The corner system is made up of an extending beam or adjutage usually, sometimes again the corner system is referred to as the corner arm that collapses, and it is connected in the outer end of girder rotationally, and is supported at least on the steerable driving pylon.Here also be provided with a guidance system, extend pylon so that when girder moves around the place, can guide or handle, or extending beam, make its abduction enter the corner position in place.Perhaps the method that pylon is extended in the most general guiding adopts United States Patent (USP) 3,902, the 668 disclosed wiring systems of imbedding exactly.

Be provided with a plurality of water jets that are spaced apart on the girder and on extending beam.Water jet on the extending beam has only when extending beam outwards moves into the corner position in place and just starts.And to provide uniform water distribution will produce difficulty at the corner position in place, this is owing to begin outwards to move that the zone that water jet covered on the extending beam is the zone of a variation in the process of launching to enter corner position, place at extending beam, the situation when launching fully unlike extending beam.In addition, identical situation also appears when adjutage during from the withdrawal of its position of launching fully.

Up to now, be to open or close at one group of water jet on the extending beam according to the angle between extending beam and the girder.This has just caused some local pouring too much, and some local pouring is not enough, decides on the residing position of extending beam.

Summary of the invention

Therefore, the main purpose of the present invention provides the device at corner position, a kind of improved irrigation field ground, and this device has been eliminated the phenomenon that pouring is too much or pouring is not enough.

Another purpose of the present invention provides a kind of angle watering system, this system adopts two water pipelines on extending beam, the jet size of the water jet that is provided with on water pipeline is increased outward by the inner of extending beam, and the jet size of the water jet that is provided with on another water pipeline is reduced to the inner by the outer end of extending beam.

The corner that has of the present invention is striden the center whirling irrigation system of arm attachment and is comprised a center rotation supporting construction that is arranged in the pouring place.The one microscler main water beam with inner and outer end rotates the supporting construction rotation with its inner around the center, and outwards stretches thus.Main water beam is made up of a microscler water main line that is supported on the driving pylon of a plurality of non-manipulations, and the driving pylon of non-manipulation is promoting the revolution of water main wire-wound center rotation supporting construction.One has the microscler extending beam of inner and outer end or corner strides arm and is rotatably connected to its inner on the outer end of girder, and extending beam includes one and is supported on the microscler extension water pipeline that can handle on the driving pylon at least.

On girder, be provided with a plurality of water jets that are spaced apart, to irrigate the place of girder below.Along the water jet that is provided with two row variable flow rates or pulsation flow rate on the extending beam.The jet size of delegation's water jet is increased outward by the inner of extending beam, and the jet size of another row water jet is reduced to the inner by the outer end of extending beam.The two capable uses that combine mutually will be executed the water yield of irritating suitable on all positions that extending beam moves.

Embodiment

Automatically advance irrigation system 10 to be made up of a center whirling irrigation system 12, the latter is provided with a corner that is connected in its outer end rotationally and strides arm irrigation system or extending beam 14.In general, center whirling irrigation system 12 designs in the usual way, and it comprises one from center rotational structure commonly used 18 outside water main or the girders 16 that stretch.Girder 16 is supported on a plurality of driving pylons 20 in a usual manner.Driving tower design becomes can promote the center rotary system to move around the center rotational structure in a usual manner.The corner arm, corner is striden arm, and corner beam or extending beam 14 are supported on to handle and drive on the pylon 22.

Consult Fig. 2, the outermost end pipe fitting of girder 16 is partly represented with 24.Supporter 26 is fixed tightly on the dihedral plate 28 that is installed on pipe fitting part 24 outer ends, and a connection ball 30 is installed on himself.Supporter 26 comprises a bend pipe or a curved ancon 32, and it is downward by pipe fitting part 24, outwards also stretches out backward, sees Fig. 2.One end of tube connector 34 is installed on the curved ancon 32, and is fixed on the curved ancon 32 with holder 36 commonly used.The other end of tube connector 34 is fixed tightly in a flanged pipe 38, and the latter is suitable and tighten up with flange 40, and flange 40 is the following the inners that are fixed on pipe fitting 42, and 42 of pipe fittings are to stretch downwards from the inner of water pipe 44 that corner is striden arm 14.Flange 46 is installed in the inner of water pipe 44, and is covered by a plate 48 that is provided with overarm 50.Overarm 50 downside be provided with one with connecting ball 30 adaptive spherical receptacle 52, see Fig. 4.

As shown in Figure 5, corner is striden arm 14 along with the girder motion, and outwards launches to move into the corner position 53 in place 54, and like this, the corner position in place just can obtain in the mode of routine irrigating.Corner is striden arm 14 and is comprised that one extends water pipe 44, and as mentioned above, this extension water pipe is provided with the water jet 56 of a plurality of alternate separations thereon.Each water jet preferably the variable flow rate type or pulsation flow rate type, and control by the hydraulic pressure that is provided with it on/magnetic valve combination 58 or similar control piece.

For the purpose of the convenience that illustrates, water jet 56 is considered to include water jet 56A and 56B.First hydraulic pipe 60 is arranged on a side of pipe fitting 44, and along the length extending of pipe fitting 44, and second hydraulic pipe 62 is arranged on the opposite side of pipe fitting 44.Hydraulic pipe 68 extends to valve 58 on the water jet 56A from pipe fitting 60, and hydraulic pipe 70 then is stretched over valve 58 on the water jet 56B from pipe fitting 62.The common plot of water jet 56A is controlled, and the common plot of water jet 56B is controlled.In other words, water jet 56B then closed when water jet 56A opened, and vice versa.The jet size of water jet 56A is increased outward by the inner of extending beam.The jet size of water jet 56B is increased to the inner by the outer end of extending beam.The startup of water jet 56A and/or water jet 56B can be controlled by means commonly used, for example common corner part parallactic angle degree sensor that adopts, and its detects the angle of extending beam with respect to girder.By using two row water jets in combination, just can on collapsing all positions of arm operation, corner execute the suitable water yield of filling.

This shows that the present invention has finished the purpose that it proposed.
