Information confirming the possibility of implementing the claimed invention are as follows.
Multisupport sprinkling machine (see Fig.1) contains irrigated by discharge pipe 1 with a sprinkling apparatus 2. Discharge pipe 1 is mounted in the wheel bearings 3. One of the wheel supports 4 are the leading and equipped with the hydraulic motor 5. It is connected with the control line 6. Irrigation pressure pipe 1 through a flexible hose 7 is connected with the hydrant 8 mounted on a stationary closed pipe 9 of the irrigation system. Torque from the hydraulic motor 5 is transmitted through the bearing 4 for improved towing characteristics of the sprinkler. From the discharge pipe 1 receives the rotation of the wheel Assembly 3. Hydrant 8 hydraulically connected with a flexible hose 7, irrigation pipe 1 and sprinkler apparatus 2. Hydrant 13 is hydraulically connected via a control line 6 to the hydraulic motor 5.
By pressure pipe 1 (see Fig.2) made in the form of sections 14 and 15 of the supporting frame of the opposed set of the C-shaped cold-formed sections with flanges 16 and 17 at the ends. In the cavity of the supporting frame sections 14 and 15 posted by water conveyance belt in the form of pipes 18 and 19 of high pressure polyethylene. Pipes 18 and 19 with stepped sections are reduced discretely in the direction of flow of irrigation water in cavity water conveyance belt. The ends of the pipes 18 and 19 in sections 14 and 15 are coupled by a coupling 20. Adjacent the bearing frame sections 14 and 15 are connected by means of the fastening elements 21 through a spacer sleeve 22.
The coupling 20 (see Fig.3) for connecting pipe ends 18 and 19 of high pressure polyethylene has a mating flanges 23 and 24 with the pipes 25 and 26. The surface of the nozzles 25 and 26 have a protruding threaded sections 27 and alternating with them grooves 28. Threaded sections 27 pipes 25 and 26 are screwed into the ends of the pipes 17 and 18. The mating ends of the pipes 17 and 18 covered bandolinoblu and sprinkler apparatus 2. The nipple 31 is oriented in a space formed between the short horizontal shelves installed-shaped bent shape of the supporting frame. Mating pair of flanges 23 and 24 provided with a labyrinth seal 32. The coupler 20 has a means 33 for dismantling. On the periphery of the flanges 23 and 24 are made radially oriented grooves 34 for screwing the pipes 25 and 26 in the cavity adjacent pipes 17 and 18 (see Fig.4).
The coupling 20 (see Fig.3) made in the form of rostrubo of truncated hollow cones 35 and 36, associated General basis, having the smallest diameter. The flanges 23 and 24 are interconnected by means of fasteners 37.
The length of the distance bushings 22 4...5 times greater than the thickness of the flanges 23 and 24 (see Fig.2) clutch 20.
Multisupport sprinkling machine operates as follows.
For multisupport sprinkling machine is mounted on the plot to the left of the hydrant 8, with the axis of the discharge pipe 1 perpendicular to the stationary pressure closed pipe 9. Flexible sleeve 7 is attached to the hydrant 8 and opening the valve, the machine starts to work. Water from the hydrant 8 through a flexible hose 7 is supplied into the cavity of power belt of the pipes 18 and 19. Of the pipes 18 and 19 through the nipple 31 water napravle surface irrigated area. Water from the hydrant 8, moving in the cavity of the tubes 18 and 19 of variable cross-section, is consumed by the apparatus 2, and the length of the power zone pressure and the speed of its supply are reduced. To ensure uniform watering and preserving the quality of the rain, the diameters of the pipes 17 and 18 discretely and sequentially from one section 15 to the other sections 14 are reduced. This is achieved by equal working conditions sprinkling apparatus 2 along the length of the rolls of the pipeline 1. This reduces the amount of water in the pipe 1 and the load to the supports 3 and 4.
After making a given irrigation norms operator sprinkler closes the valve of the hydrant 8 and opens the valve on the hydrant 13. Water under pressure in the control pipe 6 enters the hydraulic motor 8. Waste water from hydraulic poured on irrigated land. During the operation of the hydraulic motor 8 through a chain transmission receives the drive support frame sections 14 and I5 by pipeline 1. From pipeline 1 intermediate chain drives get a pair of wheel supports 4 by moving the Central section of the pivot. The lateral connecting sections 14 and 15 during the rotation of the pipe 1 transfer efforts on rolling wheeled supports 3 by means of flanges 16 and 17 through distance is 13. Rolling wheel bearings 3 and 4, the operator aims the nipple 31 on the pipes 18 and 19 to be placed in an upright position, gently closing the gate valve on the hydrant 13.
Next, a flexible hose 7 disconnects from the hydrant 8, and the control pipe 6 from the hydrant 13. The sleeve 7 carries on the hydrant 13, and the pipe 6 to the next hydrant on a closed pipe 9. When you open the valve on the hydrant 13 sprinkling machine begins to work at his new position.
The labyrinth seal 32 on the flanges 23 and 24 of the coupling 20 prevents leakage of water and does not require precise alignment when connecting pipes 18 and 19 of the power zone. By means of screws 33 on the flange 23 is maintained equal to the gap in the labyrinth seal 32 in pairs of flanges 23 and 24.
To replace the pipe 18 and pipe 19 in sections 14 and 15, the operator enters the following way. Releasing the bolts and nuts of fastening means 21, removes the spacer sleeve 22 between the flanges 17 and 16 in section 15. Next carob keys with maw on 17 and 19 mm frees bolts and nuts fastening means 37. Releasing the lock nut on the screw means 33 dismantling, gradually worachet in the flange 23 of the coupling 20. When screwing in the screws flanges 23 and 24 and the sleeve 20 are mutually separable. The malleability of the pipes 18 and 19 allows between the rings Labiau or aluminium strip from ZIP sprinkler. Similarly releases the flanges 23 and 24 on the second end of the pipe 19 in section 15. After placing the strips between the flanges, screws, tools dismantling 33 vivencial. Wheel support roll 3 with the supporting frame and the pipe 19 outside of the pipeline 1. A special key for the slots 34 in the flanges 24 and 23 sbencivu nozzles 26 and 25 of the ends of the pipe 19. Axial movement, the preliminary removal of the nipple 31 sprinkling apparatus 2, from the cavity of the supporting frame remove the pipe 19, which is either replaced with new or subjected to repair. The Assembly of the pipe 19 and the flanges 23 and 24 are produced in reverse order.
The same applied to pivot the flow of water there is the possibility of using Bolsheretsk sprinkler apparatus 2 having a large radius of action. Due to this growing band of moisture position, reduces the number of idle travel, it saves one-time capital costs. Power belt with discretely decreasing cross-section to provide high quality rain. The distribution of functions between the power belt and bearing frames provide the machine's service life for the entire period of operation.
