The invention relates to agriculture and can be used for irrigation of agricultural crops furrow.

Known design multisupport irrigation pipeline [1], including water conveyance pipeline, mounted on wheels, intake coupling, mounted on the pipeline and flowlines connected to the couplings and is made with the water outlet holes, and irrigation plumes attached to the couplings can be rotated about their axis.

A disadvantage of the known solutions is the complexity of the design of the node connecting train to the water conveyance pipeline, which is designed in the form of a rotating pipe coupling, equipped with sealing elements, supporting rollers, the centering position, relative to the surface of the pipe and sealing elements.

When operating multisupport pipeline under the influence of its own weight of water conveyance pipeline bending in the vertical plane, and when the movement of the pipeline under the influence of the microrelief is bending in the horizontal plane. Under the action of these forces water conveyance pipeline is subjected to deflection of transverse bending. When bending the pipe is jamming of the support roller clutches, resulting in increased efforts n the rotating them and moving multisupport pipeline. While the resulting distortion of the surface water conveyance pipeline leads to increased wear of the surface of the pipeline rollers, which shortens its lifespan, and the change in the predetermined clearances between the sealing elements and the surface of the pipe when bending leads to water leaks.

In addition, the lack of known construction multisupport the drip line is that moving the rigid fastening of irrigation plumes on the clutch when bending water conveyance pipeline leads to a transverse offset of the starting areas irrigated plumes along the crests of the grooves, and this leads to damage to agricultural crops.

Another disadvantage of known construction multisupport the drip line is that its use is effective for areas a large area, when to move it use energy truck with a gasoline or electric engine. When using multisupport irrigation pipes on plain areas where the pipeline has a small length, to use material-drive truck to move it efficiently.

Short multisupport irrigation pipelines, in whole or in its individual sections can be moved manually in the usual rolling. However, for displacement is possible multisupport pipeline of known construction, a need arises each time razbalyvali to move and connect to the irrigation pipe water conveyance pipeline, and this is due to labor costs, and time to prepare for flooding, which generally reduces operational capabilities known watering device.

Partial elimination of this disadvantage by stabilizing the position of the initial part of the train when it is moving is achieved in the known construction multisupport irrigation pipeline [2], which made the closest technical solution.

Known design multisupport irrigation pipeline [2] includes water conveyance pipeline to the driving wheels, freely rotating on it water conveyance clutch, which are attached equipped with floodgates flexible flowlines and United with them guides traction elements.

The disadvantage of known construction multisupport irrigation pipeline lies in the complexity of the design of its rotating couplings. The presence of these moving elements of the support rollers and the sealing cuff reduces the reliability multisupport irrigation pipeline.

In actual use, the bending of the water conveyance pipeline causes jamming of the rollers on the surface of the water conveyance pipeline and leads to mechanical damage to pipe in place of the rotary coupling.

Sealing elements over time, undergoing a natural starane is, lose their elasticity, and uneven exposure to stress leads to uneven wear and the formation of water leaks. All this reduces the reliability of the drip line and shortens its service life.

A large mass of the coupling increases the natural deflection of the pipe water conveyance pipeline requires increased effort to move multisupport irrigation pipeline.

Another disadvantage of the known design of the drip line is the complexity of the mechanism of stabilization of the initial section of the drip trail consisting of two converging rods. In the upper part of the traction elements are mounted on the clutch on either side of the node connecting the spray plume at a distance greater than at the bottom, where they are installed on the train. This arrangement rods when moving train creates the conditions for capturing the aerial parts of plants between the traction elements, which is collected in a narrow place, in the place of fastening rods on the train. This leads to damage to above-ground parts of plants or their simple pulling out of the moist soil.

In addition, the known device thrust stabilize the position of the primary sections of the drip line only in that case when water conveyance pipeline is absolutely rigid construction, and the relocation is carried out simultaneously throughout the length.

In operation the movement of the pipeline starts from the place where it is accompanied by force, i.e. in the setup drive truck, and while the magnitude of the transmitted torque will not exceed the required loads, extreme wheels irrigation pipeline will remain in place, and the middle part of the pipeline begins to move. The backlog at the wheels can be up to 5...8 rows. The resulting bending water conveyance pipeline in a horizontal plane leads to the decrease of the distance between the irrigation plumes. Installed thrust in the known device stabilizes the initial areas of irrigation loops, making flexible train harder. Resulting in all the initial part of the spray plumes will move not strictly perpendicularly across the furrows, and slid off their crests with them plants, which will increase their seminarist.

Another disadvantage of the known multisupport the drip line is that its use is effective in the large city areas, where they have a length of up to 300...400 m, and their movement is carried out using energy truck with a gasoline or electrically powered.

The use of material-drive truck on short (up to 100...200 m) of irrigation pipelines for irrigation of small plots is effective. Move known construction of irrigation devices manually is difficult and time-consuming because of their lack of special equipment and need to disconnect bolting pipe water conveyance pipeline section for rolling manually.

The purpose of the invention is to simplify the construction, increase the reliability of operation of the drip line and the extension of its application conditions.

This objective is achieved in that each node connecting the spray plumes to water conveyance pipeline is executed in the form of rigidly mounted on it nozzle with a quick connection. Directly at the nozzle is rigidly fixed to a guiding device, made of two Polukarov with wheels, which slides freely detachable ring. In place of the connector ring attached to the flexible guide rod fixed to the other end in the irrigated train his quick coupling.

Along the length of the water conveyance pipeline is divided into similar sections. Water conveyance pipeline, each section provided with a quick connection. In the middle of each section to reduce the load on the operator of a water conveyance pipeline is rigidly fixed to the gate to move it manually.

The essence of the proposed solution is shown in the drawings.

N is 1 shows a General scheme of the proposed multisupport irrigation pipeline; figure 2 - node connection of the spray plume to water conveyance pipeline; figure 3 - gate to move the pipe section; figure 4 - quick coupling sections multisupport irrigation pipeline.

Multisupport irrigation pipeline consists of hard water conveyance pipeline 1, which is rigidly mounted supporting wheels 2. The pipeline 1 is rigidly installed in the intake pipe 3 with quick couplings 4 with flexible irrigation plumes with 5 outlets 6.

Next to the intake pipe 3 water conveyance pipe 1 is fixed detachable clamp 7 with the flanges 8. Between the flanges 8 on the yoke 7 is set free moving ring 9 with the connector 10.

The upper part of the spray plume 5 the dismountable joint 4 clamp 11 is fixed to the flexible rod 12, the free end of which is secured to the ring 9 in the connector 10 of the irrigation pipeline.

To move in its middle part can be installed leading truck engine, the rotation of which is transmitted directly to the pipeline 1 and the driving wheels 2.

Short multisupport irrigation pipelines his water conveyance pipeline 1, equipped with supporting wheels 2 with installed irrigation plumes with 5 nodes and their connections, is divided into uniform sections 13. In the medium is part of the section 13 to move installed gate 14.

Gate 14 consists of two Polukarov 15 rigidly mounted on the pipe water conveyance pipeline 1 and secured to them by the arms, made in the form of brackets 16.

On the borders of the water conveyance pipeline 1 each uniform section 13 installed couplings 17, each of which consists of a bracket 18 mounted on the flanges 19 of which holds the pipe 1. The bracket 18 is fixed centering finger 20 and the free roller 21 with a Cam 22. The tail roller 21 provided with a lever 23.

To connect the individual sections of irrigation pipe bracket 18 is mounted on the flange of the pipe so that the centering fingers 20 seated in the bore of the connecting flanges. The lever 23 and the bracket 18 abuts the finger 20 in the flange 19, and the roller 21 with a Cam 22 is rotated by the outer surface of the flange and coupler flange, and is provided with a tight seal.

For separation of the drip line on a separate section of the operator by turning the lever 23 in the opposite direction rotates the Cam 21, releasing the bracket 18.

Works multisupport irrigation pipeline as follows. Water conveyance pipeline 1 with the node connecting connects to the hydrant irrigation network, and after it is opened, water is supplied into the pipe 1 and through the nozzles 3 post who becomes attached to him irrigated plumes 5, and then through the outlets served in irrigation furrows.

After watering, the operator detaches the multisupport irrigation pipe from the hydrant. The remaining water conveyance pipeline water flows in irrigation loops 5. The operator, passing along the drip line disconnects quick coupling 4 irrigation loops 5 and nozzles 3. When removing loops and pipes from the water supply pipe 1, the loops are held by the ring 9 with the help of the flexible rod 12, one end of the fixed ring in the connector 10 ring 9 and the other on the irrigation train 5.

If multisupport irrigation pipeline drive truck torque from it is transferred to the water conveyance pipeline 1 and fixedly mounted thereon supporting wheels 2. While the loops 5 are held on the pipe 1 by means of the ring, freely rotating on the prescribed yoke 15 with limiting its movement by the flanges 8 along the pipeline.

In the absence of driving trucks on multisupport the pipeline operator divides it into separate sections by turning the lever 23 quick coupling. Causing the rotatable roller 21 with a Cam 22 releases the bracket 18, and sections 13 are disconnected. The operator, resting his hands on the levers 6 gate 14, manually turn rolls unified sections on but the current position to the next hydrant irrigation network.

In his new position operator, passing along the pipeline connects quick couplings 4 irrigation loops 5 to the water conveyance pipeline 1. If irrigation pipeline moved separately in sections, the operator by turning the lever connects the partition 13 into a single pipe that connects it to the hydrant irrigation network, gives him water, and the watering process is carried out in the same way.

Proposed truss has upper and lower chords, central panel in form of regular pyramid with square base and left-hand and right-hand cantilevers mated with pyramid. Central panel has square base made of tubes with flanges for connecting lower chords and four suspensions orientated along ribs. Panel is provided with one post located on one of side faces along apothem of pyramid. Each cantilever consists of thirteen intermediate panel and one end panel. Each end panel is made up of two posts, one brace, two front and rear water tubes of lower chords, one upper chord, two tilted struts and two horizontal tension members. Two heads are fitted on each intermediate panel and end panel. End is made in form of guy-rope truss. It is mated with truss panel by brace and tilted posts. Ends of tilted posts are relative mated from top and bottom by horizontally orientated brace. Mated ends of tilted posts are orientated downwards and arranged lower than brace. Ends of front and rear water tubes in guy-rope part are relative mated by V-shaped water supply member with tube of truss guy-rope part. Panels of guy-rope part of truss are formed by posts and braces, tilted struts and tension members orientated in longitudinally vertical plane. water supply pipeline of guy0rope part is furnished with drain valve. Proposed truss provides 15-20% reduction of materials usage.

EFFECT: improved quality of sprinkling, facilitated servicing.

FIELD: agricultural engineering, in particular, irrigation equipment, more particular, continuous motion sprinkler machines for farms.

SUBSTANCE: girder has central panel with two cantilevers pivotally fixed thereon. Each of two cantilevers is made in the form of mutually perpendicular vertical and horizontal girders having belts, columns, angle braces and sprinkler heads on water supply girder. Pipelines on central panel and water supply girder are made in the form of curved circuit line in transverse-vertical plane of sprinkler unit. Circuit line equation is y=a/2(ex/a+e-x/a), where a is distance from surface of field to be irrigated to pipeline arranged in mid portion of central panel; e is Napierian base (Napierian number); x and y are abscissae and ordinates of unknown points of pipeline in Cartesian coordinates XOY, the beginning part of which is aligned with field surface and with vertical axis of symmetry of girdle.

EFFECT: enhanced reliability in operation and increased efficiency.
