Description

The invention relates to agriculture, in particular to sprinkler machines.

Known double-console sprinkler unit type DDA-100MA, DDA-100VH, taking water from an open temporary sprinkler (Nomenclature catalog of sprinkling equipment and equipment. Part 1 "Domestic equipment". - M., 2001, p.5). The farm in the form of a spatial structure with sprinklers is mounted on a tracked tractor with a creeper. There is a water intake device, pumping and power equipment driven by a tractor PTO.

The disadvantages of this design is the presence of a constant energy source (tractor), high power costs for the formation of the rain zone.

Known multi-support sprinkler machine, including an additional pipeline with sprinklers, self-propelled support carts with hydraulic actuators, hydraulically connected to an additional pipeline connected at one end to the beginning of the water supply pipeline (AS No. 1665978, IPC A 01 G 25/09). The additional pipeline has two branches: a conveyor and an intake, from which the cylinders drive self-propelled carts. In addition, at the end of the machine, these two branches are connected, i.e. looped.

The disadvantage of this technical solution is the large consumption of materials, the presence of the supply piping network and increased pressure to ensure the operation of hydraulic drives, the complexity and inability to use on an open irrigation network.

The front-end sprinkler machine of the Mini-Frigate-FS type, with water supply from a hydrant of a stationary pipeline (Nomenclature catalog of sprinkling equipment and equipment. Part 1 “Domestic equipment”, is proposed and produced by the domestic industry. - M., 2001, p. 36- 38). It consists of two trusses of a water supply pipeline, based on three trolleys having hydraulic wheels. In addition, there is a directional movement system with a guide cable, blocks for synchronizing trolleys and automatically switching off the DM. Powering the trolleys and synchronization unit is carried out separately for each trolley from the water supply pipeline DM.

The disadvantages of this technical solution include the presence of a supply pipe network and a flexible hose, high heads and increased costs.

Known sprinkler machine frontal movement with electric, hose "Mini-Kuban-FSH" with a water supply from a hydrant (Nomenclature catalog of sprinkling equipment and machinery. Part 1 "Domestic equipment". - M., 2001, p. 18-20). It consists of a water supply pipeline supported by three self-propelled carts, and two cantilever pipelines with cable suspension. The wheels of the support trolleys, equipped with pneumatic tires, are driven by electric drives. In addition, the machine is equipped with electrical control systems on the course, “in line” and DM stops.

The disadvantages of this machine are the presence of the supply pipe network and a long hose, high pressure at the pumping station, high energy costs and capital investment in the irrigation system.

Known sprinkling machines of frontal displacement type DMF "Kuban - M" with water intake from an open concrete channel (Sandigursky DM, Bezrodnov NA Mechanization of irrigation works. - M .: Kolos, 1983. - P.65-75) . They represent a moving frontally conducting pipeline, consisting of two wings, supported by self-propelled carts, and a power unit suspended from the central beam and two carts in the center. The machine has heading systems with a guide cable, in-line synchronization systems and emergency stops. All of these control systems and sensors are electrical.

The disadvantages of this technical solution include the complexity and bulkiness of the design, high monetary and material costs, additional costs for laying electrical communications to control and synchronization systems, the need for a powerful diesel engine and pumping equipment.

The objective of the invention is the elimination of these shortcomings and the use of low-pressure equipment and a low-power engine in the design of frontal displacement DM with hydraulic drive and water intake from an open irrigation network.

The technical result is a reduction in energy costs for irrigation when using low-pressure pumping and power equipment, increasing the reliability and uniformity of movement of running gears.

This is achieved by the fact that the machine is equipped with an additional pump with an independent drive from the internal combustion engine, while the additional pump is the second stage of the main one with the ability to supply water to the power lines of the central and peripheral bogies, separate from the water supply pipeline, and the control system along the course and in line is hydraulically interconnected and built into the power lines of the central and peripheral carts.

Figure 1 presents a General view of the frontal DM, figure 2 is a diagram of the water supply to the plumbing and additional pipelines of the machine.

The front-displacement sprinkler includes a water supply pipe 1 with sprinklers 2, self-propelled carts: central 3 and 4 and peripheral 5, 6. Masts 7 and cable 8 form a cable-stayed truss of the machine. Between the central bogies 3 and 4, a special-purpose diesel engine 10, main 11 and additional 12 pumps, valves 13, 14 are installed on a special frame 9. The power line for peripheral bogies 5, 6 includes pipelines 15, 16, a traffic control system in line 17, cylinders 18 and 19. The power supply line of the central bogies 3, 4 consists of a heading control system 20, highways 21, 22 and cylinders 23, 24. Between the system 17 and 20 there is a hydraulic connection 25. The machine has a water intake device 26 that allows water to be taken from the temporary sprinkler 27 .

Sprinkler machine operates as follows. When the internal combustion engine 10 is turned on and the water intake device 26 is lowered into the temporary sprinkler 27 after start-up, the main pump 11 is operated. The bulk of the water is supplied by this pump to the water supply pipe 1 and, in the form of rain, falls onto the irrigated surface through sprinklers 2. Another part of the water is supplied to the inlet of the additional pump 12, connected in series with the main pump 11. They have independent drives from the internal combustion engine 10. The pressure of this part of the water flow is amplified by the pump 12 and is supplied to the supply pipes 15, 16, 21, 22 of the cylinders 18, 19 peripheral 5, 6 and central 3, 4 carts. In addition, traffic control systems for line 17 and at the heading 20 are included in these power lines for central and peripheral bogies. The first system 17 regulates the water supply to the cylinders 18, 19 taking into account the lag or run-in of the corresponding peripheral bogie 5 or 6, the other (20) - regulates the flow of water into the cylinders 23, 24 of the central bogies 3, 4 depending on the deviation from the linearity of movement (along a cable or other device). Between the motion control systems in line 17 and at heading 20 there is a hydraulic connection 25. Gate valves 13 and 14 seal the cavity of the main pump 11 at startup.

The invention in comparison with the prototype has the following advantages:

- separation of the power lines of the cylinders of the drive of self-propelled carts from the water supply pipeline allows the car to be driven across the field without irrigation (for technological needs: harvesting crops, plowing the field, etc.);

- the introduction of an auxiliary pump, consuming 5 ... 7% of the main power, makes it possible to provide increased pressure (especially peripheral) in the supply lines of the cylinders of the drive of self-propelled carts, their stable travel on various agricultural backgrounds, while maintaining a low pressure in the water supply pipe, where the main amount of water (93 ... 95%);

- allows to reduce capital investments in the irrigation system by 30 ... 40% due to the use of reduced power of ICE and low-pressure equipment and accessories;

- an increase in the speed of movement by 15 ... 20%, and consequently, a decrease by the same percentage of the minimum irrigation rate in one pass of DM.
