Description

The invention relates to agricultural machinery, in particular to mobile irrigation equipment, can be used in double-console sprinkler units and sprinkler machines of the drum type strip irrigation equipped with sprinkler farms.

Known two-console sprinkler unit DDA-100MA-1 (Technical description, instruction manual DDA-100MA-1, Kiev "Hour", 1990).

Truss DDA-100MA-1 is a three-belt spatial construction with one upper and two lower belts. It consists of two consoles, which are interconnected by a central part. Each console consists of 13 panels and one end. The panel consists of two racks, one strut, two water pipes of the lower belt, one upper belt, two braces, two stretch marks.

All elements of the farm are made of steel and protected against corrosion by paintwork. Internal surfaces of pipes are not protected from corrosion. The pipes of the lower chords are made of the same length, but of variable cross section, decreasing from the center of the truss.

The farm is mounted directly on the tractor and its stabilization is carried out by four hydraulic cylinders working in pairs. Operates hydraulic cylinders directly by the operator.

The DDA-100V two-console sprinkler unit is known (the DDA-100V two-console sprinkler unit instruction manual, Ortekh CJSC, Volgograd, 1995), as well as the patent (RU No. 2222184, IPC A01G 25/09, two-console sprinkler unit) .

Farm DDA-100V also consists of 2 symmetrical consoles. Each console consists of 13 panels and one end.

The panels from the central part to the 6th are identical to the panels of the DDA-100MA-1 truss, the 5th panel is transitional, it has a two-belt spatial design with two upper and lower belts. The end part of the truss (four panels and the end) is single-belt in the form of cable-stayed suspension. The farm is connected to the tractor through a tower made in the form of a rectangular pyramid. The farm with the tower is pivotally connected in the upper zone, which allows it to take a stable horizontal position.

When working on rough terrain, it is controlled by a tractor operator using a hydraulic cylinder connected to one of the consoles and the tractor.

The disadvantages of the two-console trusses considered include high metal consumption, short service life due to low protection against metal corrosion, the difficulty of transporting over a long distance in assembled condition, especially in rough terrain and the presence of forest belts, large hydraulic pressure losses along the length of the pipeline, increasing with service life.

The farm is mounted directly on the tractor; when using the tractor for other agricultural work, the farm and pumping equipment must be dismantled, which creates certain difficulties.

Known are mobile sprinkler machines of the drum type of strip irrigation, equipped with two-console trusses mounted on a special trolley, the water supply belts of which are made of steel with hot-dip galvanizing of the internal and external surfaces, and part of the pipes, as a rule, of the end pipes, are made of aluminum alloys.

At the same time, to give the lower water-conducting belt longitudinal stability in the vertical plane, each panel is suspended by a cable to the central part of the truss. The panels are interconnected in the lower zone pivotally. To give horizontal rigidity, a flat truss is pivotally mounted at a 90 ° angle. When transferring the truss to transport position, the flat truss is placed vertically, and the panels rotate around a vertical axis, starting from the end, stacked on top of one another.

Such sprinklers are manufactured by Waer (Austria), these are Rainstar EAS5O, Rainstar TAS32, (instruction manual for Rainstar RAS5O and TAS32 series, version, June 2003).

The advantages of the two-console farms considered include the ability of the water supply belts to perform two functions, that is, to perceive power loads and transport water to the spraying working bodies. The hinge of each panel makes it possible to fold the console panel-wise in a vertical plane and it is relatively easy to transport the sprinkler with the farm to both winter storage areas and irrigated fields.

The disadvantages include high metal consumption, large pressure losses along the length of the water supply pipeline, high rain intensity due to the use of nozzles with a round torch, and a relatively short service life of the water supply belt.

Domestic manufacturer Ortech CJSC, Volgograd, produces such mobile sprinkler irrigation machines of the drum type strip irrigation. A distinctive feature of these machines is that their water supply belt is also made of steel, but corrosion protection is carried out by coating only the outer surface without preliminary preparation, which significantly reduces the service life of the water supply pipe pipes.

The closest analogue to the claimed object in its essence and in the number of features includes two-console trusses of sprinkler machines of the Bauer firm (Austria) Rainstar EAS50 and TAS32 series.

The invention consists in the following.

The problem to which the invention is directed is to increase the operational performance of mobile sprinkler machines equipped with double-console farms.

EFFECT: increased service life, process reliability, reduced hydraulic losses in the water supply pipeline, and improved quality indicators of artificial rain.

The specified technical result is achieved by the fact that in the well-known farm of a two-console sprinkler machine of a drum type of strip irrigation, including a support trolley, a central part, left and right consoles, consisting of panels containing elements providing vertical and horizontal stability, a water supply belt, spraying organs (nozzles ) wherein the panels are pivotally connected in the lower zone, according to the invention, the water-conducting belt is made of polyethylene pipes, the ends of which are pressed into metal corrosion-resistant pipes with a ribbed annular surface, with flanges at the ends, in one of the flanges in the groove a self-sealing cuff is installed. Elements ensuring vertical stability of the truss are made in the form of extensions, braces and racks. An element providing horizontal stability of the central part of the truss and the panel adjacent to it is made in the form of a frame structure, horizontal stability of the remaining panels is provided by the frame. Spraying organs (nozzles) are made deflector with a flat torch of directional action.

Polyethylene tubes are placed in a lattice frame of rectangular or triangular section with a length equal to the length of the panel, the frame is made of a bent profile of an angular, square, round or rectangular section, with jumpers around the perimeter of the frame from a bent profile of the same section.

Frames end with rectangular flanges with studs for attaching a polyethylene pipe.

The panels are additionally pivotally connected in the upper zone, and in the working position are fixed with bolt locks.

The frame design, providing horizontal stability of the panel adjacent to the central part of the truss, is made of variable cross-section.

Spraying working bodies (nozzles) in the water supply belt are installed in pairs asymmetrically with an angle of inclination of the torch to the horizon of 7-15 °.

The invention is illustrated by drawings.

Farm two-console sprinkler strip irrigation works as follows.

Let us consider the operation of the farm of a two-console strip irrigation machine in three most characteristic cases: when performing the technological process - irrigation of crops in fields with a flat terrain and slopes within ± 3 °; when changing positions to the width of the farm and moving from one site to another or transportation to a storage location.

Before starting work, the sprinkler unit of the drum-type strip irrigation equipped with a farm, install the unit at the hydrant of the irrigation network. Raise the farm and rotate the drum with the farm, placing it perpendicular to the irrigated area. Connect the flexible pressure pipe to the hydrant, deploy the sprinkler farm to the working position (Fig. 1), balance the balancers 48, fixing them on the second or third panels from the end at the required distances and at a height of 125 ÷ 150 mm from the ground, tow the support trolley to hinge system factor for a hook-on bracket 5, the sprinkler drum is unlocked, the brake drum is put into operation, the gearbox is set to neutral position and at a speed of not more than 5 km / h the truss with the support trolley is moved to the distance provided by operating manual, ensuring the normal operation of the unit.

The operator sets the required watering rate and opens the hydrant gate.

Water flows through a flexible hose to the turbine of a drum-type machine and through a long plastic pipe to the central part of the farm and further to the console panels. A jet of water, leaving the nozzles of the deflector nozzles 45, hits a flat deflector 46 and in the form of raindrops is evenly distributed on the surface of the irrigated strip.

The turbine, through a gearbox and a chain or gear transmission, rotates the drum, which, winding layer-by-layer polyethylene piping, moves the two-console truss with a support trolley to the drum sprinkler. At the end of irrigation, the operator turns off the water supply to the sprinkler, and irrigation stops.
