Description

The utility model relates to agriculture and is designed to supply water to the root layer of the soil and to the surface of the crops to create the necessary humidity and microclimate, providing increased yield.

The following technical solutions are known from the prior art.

Known sprinkler machine (RF patent No. 2535158, 10.12.2014), including self-propelled carts with drives, a water pipe with sprinkler nozzles. The water supply pipeline is made of polyethylene pipes, which are laid on the spans of the carts, made in the form of tensed volumetric trusses of the bridge type of triangular section, which at their ends are articulated to self-propelled carts. The braces of the trusses forming the sides of the triangle are attached to the longitudinal corner at the top of the truss in such a way that their ends are above this corner, forming goats in which polyethylene pipes are laid and fastened, connecting with their flanges to short pipes on self-propelled carts.

Known wide-sprinkler sprinkler machine (RF patent No. 2520984, 06.27.2014), including irrigation pipe made sectional and equipped with sprinkler nozzles, wheel bearings, a drive located in the middle of the Central section, and couplings for connecting the sections. The irrigation pipeline is fixed on the brackets of the drive trolleys and support wheels installed on the aisles of crops of crops at a height of 2.0-2.5 m from the soil surface. The bracket of the central drive trolley has a forward triangular pivoting boom for attaching extension cables connected to the brackets of the drive trolleys and the support wheels of the side sections, an engine designed to transmit torque to the drive trolleys using a drive shaft mounted on outboard bearings placed on the brackets drive trolleys and support wheels with chain gears.

The closest analogue to the proposed solution is a sprinkler machine (RF patent No. 157637, 12/10/2015), including a water supply pipeline consisting of pipe sections and supported by support sections from trusses and moving wheel support trolleys installed at the end of each support section, each trolley is installed electrified automatic control unit, frame structures of trolleys are formed by profile elements.

The disadvantages of the known solutions are the lack of stability of the support sections of the machine against tipping over under the influence of external factors.

The technical problem to which the claimed utility model is directed was to improve the operational characteristics of wide-grip circular and frontal sprinklers in comparison with the known analogues.

To solve this problem, an irrigation electrified wheeled multi-support wide-grip automated self-propelled reversible machine of circular or frontal movement with or without a power plant, water intake from an open irrigation canal or a closed irrigation network, irrigated in motion, designed to irrigate various crops, including high-stemmed ones, was developed , in all irrigation zones and can be used on any type of soil at around the clock nom automatic operation of the machine without operator intervention.

The technical result of the proposed solution is to ensure uniformity of movement of the machine across the field and, accordingly, uniform irrigation of the entire irrigation area during round-the-clock automatic operation of the machine without operator intervention, which is achieved by increasing the stability of all support sections against tipping over while the machine is moving across the field when the influence of external factors (strong wind, uneven terrain, etc.).

The claimed technical result is ensured by the design of a wide-sprinkler sprinkler, including a water supply pipe consisting of sections of galvanized pipes and supported by supporting sections of galvanized trusses and moving wheel support trolleys installed at the end of each support section, an electrified automatic control unit, frame mounted the carts are formed by metal corners, while the pipe sections are interconnected by a flexible hose connection HAND gimbal type pipe sections in equal distance from each other bends are made with flexible hoses, comprising sprinklers with additional weights on the ends.

In order to improve the operational characteristics of the wide-sprinkler sprinkler, the height of the support trolleys and, accordingly, the distance from the soil surface to the water supply pipeline varies from 3.5 to 4.0 meters. This allows agricultural vehicles to pass freely under the sprinkler for fertilizing and / or plant protection products, as well as for other irrigation and drainage operations.

The supporting wheel trolleys are designed to support and move the machine’s water supply pipeline along the irrigated area. The trolleys are equipped with a gear motor, cardan shafts, wheel gears and pneumatic wheels. In order to increase the reliability of the machine against tipping over in strong winds in a state without water and in a state with water, the frame structures of the support wheel trolleys are made of metal corners of 100 mm in size. Due to the strengthening of the frame structure of the bogies, the stability of the support sections during the movement of the machine along the field and the uniformity of movement are increased, due to which uniformity of irrigation of the entire irrigation area is achieved.

The intersectional articulation of the sprinkler is a flexible gimbal connection. This type of connection consists of two plug flanges, interconnected by a high pressure rubber pipe with a diameter equal to the diameter of the water pipe. The rubber pipe is fastened to the flanges by pipe clamps. 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 the 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 on its outer side of the reinforcement. The proposed type of connection provides stability of the support sections when the bogies are deflected relative to the axis due to additional fastening elements that limit the bending of the machine sections.

The water supply pipeline is designed to transport water along the entire length of the machine with specified hydraulic parameters (flow, pressure) and install sprinklers (sprinklers) on it. In the pipelines of the sections there are bends in the form of U-shaped nozzles screwed into the holes along the upper generatrix of the pipeline along its entire length at equal distances from each other. Flexible hoses are attached to these pipes, on which sprinklers with loads from swinging the supporting structure in the wind hang. For a uniform distribution of water, U-shaped nozzles are directed sequentially in opposite directions from the axis of the main pipeline. The watering belt of the sprinkler is based on support carts and is symmetrical to its central axis. Sprinklers are installed along the entire length of the machine at an equal distance from each other inside the support section and are selected (by flow rate) in such a way as to ensure uniform irrigation over the entire area, as well as maintain the balance of the machine sections during movement with and without water.

The wide-sprinkler sprinkler is equipped with a reverse and a speed regulator, which allow you to change the number of its working passes in the field for issuing a given full irrigation rate, and also has the ability to move without watering.

Further, the solution is illustrated by reference to the figures, which show the following:

FIG. 1 is a general view of a support section of a wide sprinkler sprinkler.

FIG. 2 is a general view of a support trolley of a wide sprinkler sprinkler.

FIG. 3 is a general view of the central support of the wide sprinkler sprinkler.

FIG. 4 is a diagram of a wide sprinkler farm truss.

The circular sprinkler is rotary around a central rotary support 11 with a rotary elbow 20 of the water supply pipe 1, consisting of separate trusses 2 interconnected by a flexible hose connection of the cardan type 9, and resting on supporting carts 4, driven by electric motors, at the end of the pipeline located console supported by cables (not shown). The sprinkler can water both a full circle 360 °, and a sector and is designed to work in one position.

The front and circular sprinklers operate on the same principle, differing only in the nature of movement and the central drive support. Frontal vehicle - this is a frontal movement machine (translational movement) includes a central drive wheel support, which produces frontal movement together with trusses and support trolleys. The circular machine moves around the riser of the fixed central support with a rotary elbow through which water is drawn from the irrigation network. At the end of the machine, there is a cantilever section of the pipeline supported by cables. It is controlled by an electrified control panel located on the central rotary support. Watering is carried out around the clock in automatic mode.

In section pipelines there are bends 5 with flexible hoses 6, on which sprinklers (sprinklers) 7 with additional loads 8 hang. Sprinklers 7 are installed along the entire length of the machine and are selected (by flow rate) in such a way as to ensure uniform irrigation over the entire area.

Sections consist of galvanized pipes of a water supply pipeline 1. Pipeline 1 is supported by a galvanized truss system 2, consisting of trusses 21, spacers of span 22, struts of truss 23 and stiffeners 13 of moving wheel support carts 4. The number of sections can be from 2 to 13 and is selected taking into account the size of the fields, climatic and soil conditions of the area. The swivel of the sections is a flexible hose connection of the cardan type 9. At the end of each section is installed a two-wheeled self-propelled cart 4 with an electric drive. The support trolley includes a frame structure formed by metal angles 17, a gear motor 15, cardan shafts 18, wheel gears 16 and pneumatic wheels 14.

Central swivel bearing - a device around which a circular sprinkler moves. The central pivot bearing consists of a central articulated support supported by four inclined legs anchored in the concrete base 19. Water enters the pivot bearing from a pipe at the base of the pivot frame. Then it rises along the pressure riser and is fed from the central hinge support 15 above the field through the suspended pipelines 1 spans, forming sections of the sprinkler system. At the entrance to the machine, various pipe fittings can be installed: valves, pressure regulators, air valves, filter, flow meter, as well as a chemicalization system and liquid fertilizer supply.

The machine control system consists of a control panel located on the central support 11, control units 3 located on the support trolleys 4 and interconnected by cables laid along the water pipes 1. The control system ensures uniform movement of all sections of the support with a given identical angular speed.

When electric power and water are supplied to the central support, the machine moves around the central support and irrigates a circle with a radius equal to the length of the machine, while ensuring high uniformity and irrigation performance.

The drive of the machine is electromechanical. The power supply from the external network is fed through a cable to the control cabinet of the machine 12 and then through the electric drive control system it is supplied to the electric motors of the gear motors 15, which rotate the pneumatic wheels 14 of the carts 4 through the driveshaft 18 and the wheel gears 16. Signals are also transmitted via the cable supplying power remote control from the central control panel, information about the state of the machine is received.

Starting and stopping the sprinkler machine can be carried out both from the control panel located on the control panel 12, and remotely, from the central control panel, which can be located at almost any distance from the machine.

The proposed irrigation machine is equipped with a reverse and a speed controller, which allows you to change the number of its working passes in the field for issuing a given full irrigation rate, and also has the ability to move without watering.

All control of the machine is carried out from a central shield on the energy platform.

The sprinkler is equipped with a tracking system for the pipeline line, designed to maintain the overall straightness of the sprinkler during movement (deviations of the carts from the axis up to 1.1 m are permissible). It combines several closed loops of cables on each intermediate span, except for the pre-console, and line synchronization devices (PSL). The first trolleys begin to move. At the point of articulation of the trusses, a kink appears. The lever mechanism connected to the cable synchronization system and acting on the contact of an adjacent carriage includes an electric drive for the carriage. The central support moves last, and the process of “impulse” movement of the bogies is repeated depending on their relative position. If the sprinkler is located in a line, the tracking devices alternately turn on the engines of the support bogies.

A front sprinkler is a frontal displacement machine (translational movement), which has the same principle of operation as a circular one and consists of a water supply pipe 1, individual trusses 2, interconnected by a flexible hose connection of cardan type 9, and supported by support carts 4 .

Central drive trolley - a device that makes frontal movement together with trusses 2 and support trolleys 4 of a sprinkler machine. It can be located in the center or side and can be on 2 or 4 wheels, some of which can be driven and possibly controllable. It also houses a control panel, a diesel generator and produces water under pressure and power supply.

The system for supplying water to circular and frontal sprinklers includes the following elements: water sources, a pumping station, pipelines and / or supply channels and an irrigation network in the irrigated area.

In an open system, water enters the site through trunk, distribution and precinct channels.

A closed system consists of a network of fixed or temporary pipelines laid from the pumping station to the irrigated area and on the site itself. Stationary pipelines are laid to a depth of 0.6 ... 1.0 m (below the freezing boundary of the soil). Temporary pipelines (for one watering season) are placed on the surface of the soil.
