Description

The utility model relates to connections of sections of a water supply pipeline of multi-support wide-angle automated self-propelled sprinkling machines of circular and frontal movements. The wide-sprinkler irrigation machine is intended for irrigation of agricultural crops, as well as perennial grasses, meadows and pastures by irrigation method.

The following technical solutions are known from the prior art.

The known connection node of the sprinkler machine (US patent No. 4564224, 01/14/1986), including a sleeve with a diameter corresponding to the diameter of the pipes, fixed in the gap between the ends of the two pipes, a ring having a diameter smaller than the diameter of the pipes placed between the ends of the pipes, and connecting rods welded to the ends of pipes, including horizontal and vertical restriction rods. The ends of each connecting rod are connected to the ring by bolts allowing the rods to rotate relative to the ring.

A device for the movable connection of a rotary sprinkler device (international application No. 2014147268, 09/25/2014). The device comprises an external tubular section, firmly connected to the cylindrical rod, an internal tubular section, a hinge structure, which in turn contains an upper flat panel and a lower flat panel. These flat panels are connected in the area of the hinge structure, forming a U-shaped part connected to the tubular section.

The closest analogue of the proposed solution is a flexible connecting unit that connects both ends of the pipes relative to each other in such a way that leakage is excluded, while it is possible to bend the pipe at the connection due to the swivel. A double clamp is used as a swivel joint, allowing vertical and horizontal bends of one tubular section relative to another, but does not allow longitudinal movement of the pipe. The connection contains a horizontal plug, a vertical plug connected to the universal joint ring with bolts. The horizontal plug is rigidly attached to the free end of the pipe gap. The vertical plug is rigidly attached to the end of the pipe span adjacent to the tower. The universal joint ring can rotate freely around the vertical axis Y or horizontal axis X in accordance with the angle between the pipe segments (US patent No. 4330085, 05/18/1982).

The disadvantages of the known solutions are the small angle of the section. So, for most analogues of machines, the section has a tilt angle of 8-12 °, which can cause uneven movement and the risk of tipping over on uneven surfaces.

The technical problem that the proposed utility model addresses is the development of a flexible connecting unit for sections of the sprinkler machine, which provides reliable flexible connection of the pipeline when the machine is moving.

The technical result of the claimed utility model consists in the ability to move over uneven fields to hills and mountains without the risk of tipping over due to an increase in the angle of inclination reached up to 15-25 ° compared to analogues.

The claimed technical result is achieved due to the design of the connecting device for the spans of the water supply pipe of the wide sprinkler, including two flanges with forks connected to a rubber pipe with a diameter equal to the diameter of the water pipe, using clamps, forks connected to the central octagonal ring by means of bolts, each fork fixed to the flange by welding to a stiffener on the flange, and on the outside of the plug reinforcement is welded.

The plug is additionally welded to the stiffener provided on the flange, and the plug itself is reinforced by welding on its outer side of the reinforcement to achieve the reliability of a flexible joint. A metal bar gives a fork reinforcement. As a result, sections with a large pipe diameter of 159, 219, 250 can be made, and this assembly can withstand.

To limit the maximum horizontal and vertical bends of the sections of the sprinkler, the forks located on the flanges are attached to the octagonal ring, while the first flange-fork limits the maximum bend vertically, and the second flange-fork limits the maximum bend horizontally.

Couplings and flanges are welded, and the plug is connected by screws.

Next, the solution is illustrated by reference to the figure, which shows a General view of the connecting device. Below items 1-5, the following is shown:

Pos. 1 - plug with a flange and an amplifier (metal bar (fittings)).

Pos. 2 - octagonal ring with mount.

Pos. 3 - a rubber tube.

Pos. 4 - a plug with a flange and an amplifier (metal bar (fittings)).

Pos. 5 - reinforcing reinforcement, which is a metal bar.

When the sprinkler machine moves across the field, the extreme trolleys begin to move first. When a kink appears in the place of articulation of the trusses, the linkage mechanism connected to the cable synchronization system, acting on the contact of the neighboring carriage, turns on the electric drive of this carriage.

The proposed connection is the intersection connection of the sprinkler is a flexible hose connection cardan type. This type of connection consists of two plug flanges, interconnected by a high pressure rubber pipe 0.4 m long with a wall thickness of 5 mm and a diameter equal to the diameter of the water pipe. The rubber pipe is fastened to the flanges with clamps measuring 220-228 mm for a pipe with a diameter of 219 mm and clamps with a size of 168-160 mm for a pipe with a diameter of 159 mm. To limit the maximum horizontal and vertical bends of the sections of the sprinkler, the forks located on the flanges are attached to the octagonal ring, while the first flange-fork limits the maximum bend vertically, and the second flange-fork limits the maximum bend horizontally. To achieve the reliability of a flexible connection, the plug is additionally welded to the stiffener provided on the flange, and the plug itself is reinforced by welding reinforcement with a diameter of 10 mm and a length of 150 mm along its outer side. Between themselves, the forks of the left and right couplings interact by fixing them with 4 bolts to the central gimbal octagonal ring. Couplings are mounted to the section water pipe by 6 bolts.
