Description

The invention relates to a rural household and can be used in front-action sprinkling machines that irrigate agricultural crops and humidify the air with short-jet deflector nozzles in a fine irrigation mode. A well-known sprinkler machine, including a water supply pipeline with deflector nozzles, placement of self-propelled carts and a device for supplying water to the water supply pipe 1. A disadvantage of the known machine is a large flow of water due to its withdrawal from the open channel. In addition, the withdrawal of water from the open channel requires cleaning it from various inclusions for reliable operation of the deflector nozzles. These drawbacks can be eliminated if the irrigation machine is provided with a water intake from a low-pressure closed irrigation network. The purpose of the invention is to reduce irrigation water consumption by allowing it to be taken from a low-pressure closed irrigation network. The goal is achieved by the fact that in a sprinkler machine, including a farm with water-conducting and deflector nozzles, placed on self-propelled carts, and a device for supplying water, the latter is made in the form of tanks, placed on self-propelled carts and equipped with artesian pumps for water intake from a closed irrigation network; and additional pumps for water supply to the water conducting systems of the farm. FIG. 1 shows a sprinkler, standing above an underground reservoir of a closed irrigation network, side view; in fig. 2 is a section A-A in FIG. I; in fig. 3 is a section BB in FIG. 2; in fig. 4 - floor plan, irrigated by machine. The sprinkler is made in the form of a single-span dual-console farm 1 with water-conducting 2 lines lying on the same level with fine-dispersed deflector nozzles 3 mounted on them, the span of the farm hanging on the supporting cables 4 and hanging from them by cables 5, and the farm console on the system cables 6 mounted on the tops of the support frames 7 connected by the hook 8. The machine has two two-wheeled self-propelled bogies with reversible electric drives 9 on each wheel 10 mounted on a stand 11 capable of turning around its vertical The 90 ° axle together with the wheel 10 and its electric drive 9 connected to it has a full gear 12. Each of the supports is equipped with two hydraulic claws 13, designed to lift the machine before turning its wheels from a 90 ° reversible electric drive 14 with a chain transfer 15 to a rack 11 which is located in cabin 16. A water tank 17 with a funnel 18 is suspended under the cab, and two pumps 19 with electric drives are installed to supply water from it to the water pipe 2. To fill the tank 17 with water from the underground reservoir 20 connected to the distributor 21 of the low-pressure closed irrigation network through the automatic valve 22, a pipe 24 with a direction w, ribs 26, is suspended to the electric winch 23 through the block 24 and a low-pressure artesian pump is mounted at its lower end with a submersible electric drive, and to supply this pump with power, a cable 27 is inserted into the upper end of the pipe 25. In the working position of the artesian pump, the lower end of the pipe 25 is located in the well of the underground tank 20, and it is bent minutes down the upper end - in the funnel 18 of the tank 17. For the power supply to the drive machinery 16 installed in the cabin of the machine 28. The power plant control point located in the cab 29, comprised within the midspan between its supports. To ensure the movement of the machine only along the longitudinal axis of the irrigated floor, fixed by pillar posts 30, which are installed on the sides of the huperesek roads, telecameras 31 are installed above the tank of the cab 29, and to ensure that the car stops on the transverse road with the exact alignment of the road the sinks 32 on the hatches of the underground tanks 20 or the leaf pillars 33, under the cabins 16 {on the machine’s longitudinal axis) are installed the television cameras 34. The machine works as follows. Masha.na passes in the directions of each division (indicated by arrows in Fig. 4), whose width is equal to the width of the machine, and rework them with a frontal course, moving from one half of the floor to the other by idling the shuttle after turning the wheels to 90 °. Water from the underground tanks is drawn by artesian pumps when the axes of the pipes 25 coincide with the stand 32, while the winches 23 lower the pipes 25 into the underground tanks 20, including the artesian pumps after their descent into the position shown in FIG. 3 dotted, and raised after filling the tanks with water. After that, drive the car to another case. The car goes to the extreme cross road just like the intermediate one, but here its axis is aligned with the road axis along the gate posts 33 and after turning the car’s wheels 90 °, the car is moved to the transport position by a shuttle (with empty tanks 17) the second half of the field, stopping on the axis of the division with the help of cameras, so that the axes of pipes 25 coincided with the axes of sinks 32 on underground tanks 20. Then lift the machine with hydraulic jacks 13 by 15- .20 cm and turn its wheels not 30 ° ъ working position, simultaneously lowering the pipe 25 Reservoirs 20, filled with water tanks 17. All subsequent operations associated with irrigation of other areas, repeat in the same order as with the OP (b) 6).

The proposed sprinkler provides for high yields of agricultural crops, significantly reducing water consumption for irrigation (compared to conventional sprinkling).
