Description

The invention relates to agriculture and can be used for irrigation of fields of rectangular configuration.

A fine-dispersed irrigation installation [1] is known, which is a water supply pipe rigid in the spans between intermediate carts and flexible on these carts, with one end connected to a hydrant of a closed irrigation network and the other to a driving carriage, and the rigid span pipe links are articulated through each other elements of intermediate trolleys and are suspended from carrying ropes fixed to the tops of the supporting masts. In order to increase the coefficient of land use, by reducing rutting, the chassis of the intermediate bogies are pivotally connected to the lower ends of the support masts with the possibility of rotation of the chassis in the horizontal plane, and the rear wheels of the bogies are made with ring ribs in the middle of their rims.

The disadvantages of the described fine irrigation installation, despite the possibility of watering the corners of the square with a multi-support sprinkling machine of circular action, include intensive rutting by the wheels of the support trolleys. The depth of each rut by the end of the season exceeds 0.3-0.4 m.

Known frontal multi-support sprinkler machine [2], including a Central trolley with a water intake device, a system for stabilizing the movement of the water wings of the machine with two heading sensors. The end-carriage motion control devices are made in the form of two 2I-OR circuits, the first inputs of which are connected to timers: the master and the corrections, and the second inputs are connected to the direct and inverse outputs of two heading sensors containing limit switches that are installed with the possibility of interaction with two rods . In order to increase reliability and simplify the design, the machine is equipped with a movable platform mounted on four roller supports at the ends of the channel walls and connected by a flexible coupling to the central trolley, a device for clamping the platform to one of the side walls of the channel, made in the form of front and rear rollers of the platform supports, on one of the side walls of the channel, and the spring-loaded rollers of the supports relative to the platform on the other wall of the channel, a longitudinal guide rod mounted movably with the possibility of interaction with erased by the axes kinematically connected by rods to the front and rear rollers of the supports, as well as the termination circuit included between the outputs of the heading sensors and the inputs of the 2I-OR circuits and made in the form of an OR element, the four inputs of which are connected to the outputs of the heading sensors, timer and two trigger memory elements equipped with AND circuits at inverse inputs, the first inputs of the trigger memory elements connected to the outputs of the timer, the second to the outputs of the heading sensors, and the inverse outputs of the trigger memory elements connected to the second inputs of the 2I-IL circuits AND.

The disadvantages of the described front multi-support sprinkler include high material costs for the construction and operation of the irrigation system.

The closest technical solution is an irrigation device [3], consisting of a number of interconnected pipe sections, each of which contains a pipe section supported by a self-propelled support with a drive, and a free end, and the pipe sections are connected by flexible couplings located at the free end of one section, and pipe section, with the support of an adjacent section, and control devices for actuators of supports located at the ends of pipe sections with supports and containing switches connected through sensitive elements to the drives of supports and perceiving angular movements of the pipe sections. In order to increase the accuracy of linear movement of the pipeline, the sensitive element of the switch is made in the form of a universal joint ring located at the junction of two sections, and flexible rods connected to the free end of the section and through an articulated spacer with a universal joint ring, while the universal joint ring is connected to the sections by horizontal and vertical rocker arm, and the articulated strut through a controlled lever connected to the input of the switch.

The disadvantages of the described mobile irrigation device include high material and monetary costs for the construction and operation of the irrigation system. Under the supports of the drive wheels, due to multiple passages, a ditch with a cross section of 0.7 × 0.4 m is formed. If there is even a slight slope, water along the track flows into local depressions, which become an insurmountable obstacle for self-propelled supports with a drive.

The task for which the design of a movable irrigation device is proposed is to reduce rutting under the drive wheels of the supporting self-propelled supports due to the movement of the supporting wheels of the supporting self-propelled supports along open spirals during irrigation by irrigation of rectangular fields.

The solution to this problem is achieved by the fact that in the known movable irrigation device, consisting of a number of interconnected pipe sections, each of which includes a pipe section supported by a self-propelled support with a drive. The pipe sections are connected by flexible couplings located at the free end of one section and a section with a support of the adjacent section. The support drive control devices located at the ends of the pipe sections with the supports comprise switches connected through the sensing elements to the support drives and sensing the angular movements of the pipe sections. According to the invention, the last pipe section of an interconnected series of pipe sections is provided with an additional self-propelled supporting support with a drive. Each end pipe of the section has a water intake device that is periodically hydraulically connected to the hydrants of the first, second, third and subsequent positions on the water supply pipe of the closed irrigation network laid along the long side of the irrigated field of a rectangular configuration. At the same time, one water intake device at the end of the pipe section is brought into transport position, and the other water intake device at the other end of the pipe end section is brought into working position. The hydrants in the second water supply pipeline of the closed irrigation network are shifted by half the step of the hydrants of the first, second, third and subsequent positions of the first water supply pipeline. Each extreme supporting self-propelled support with a drive is equipped with a hydraulic support mounted opposite to the gear motor on the supporting beam between the drive support wheels. Each water intake device at the extreme pipe section is placed by means of a tee, the vertical outlet of which is equipped with a ball valve connected to a set of telescopic pipes. In this case, the lower end of the outer telescopic tube is connected to the rotary threaded sleeve by means of an elastic cylindrical sleeve, and the upper end of the inner telescopic tube is connected by elastic elements to the rotary threaded sleeve. Each elastic element in the form of a tension screw spring with screw plugs at the ends of the fastening means is fixed on flat rings, one of which is freely placed on the upper end of the telescopic pipe of the water intake device, and the other ring is mounted on a rotary threaded sleeve with the possibility of angular displacement around the vertical axis of symmetry water intake device. The axial movements of the flat rings on the inner telescopic tube and the rotary threaded sleeve are limited by stops. The elastic cylindrical coupling is fixed by means of clamps on the lower end of the outer telescopic pipe and the transitional part of the rotary threaded sleeve. The rotary threaded sleeve is equipped with control knobs for easy operation. Each telescopic tube has a seal. A swivel threaded sleeve, an elastic cylindrical sleeve and an external telescopic tube are provided with the ability to rotate around the vertical axis of symmetry of the intake device. Each swivel threaded bushing of the water intake device has the possibility of threaded pairing with a bushing located on the hydrant by means of a ball valve. Each switch, perceiving the angular movement of the pipe sections, is located at the end of the horizontal branch of the tee and has the ability to contact with rappers installed in close proximity to the hydrants. According to the invention, each hydraulic support has a power drive made in the form of external and internal mating sleeves, one of which is external by means of brackets and is mounted on the supporting beam of the supporting self-propelled support, the other, the internal movable sleeve, has a spherical thrust bearing in the form of a biconvex lens placed between thrust bearing and base plate. The axial movement of the inner sleeve into the cavity of the outer sleeve is limited by stops in the form of a ring on the lower part of the inner sleeve, and the marginal displacement of the outer and inner sleeves is limited by a clamp in the form of a rope, the ends of which are placed on the top cap on the end of the outer sleeve and on the bottom cap of the inner sleeve. At the same time, between the upper cap and the base plate there is a mechanism for returning the inner sleeve to the cavity of the outer sleeve. The specified cavity cavities through the valve and the sleeve are hydraulically connected to the pipe section of the extreme supporting self-propelled support, and the cavity of the inner sleeve through the pipe and valve with the atmosphere. The mechanism for returning the inner sleeve to the cavity of the outer sleeve is made in the form of a package of cylindrical twisted tension springs, the ends of which, by means of threaded plugs and fasteners, are placed around the perimeter of the upper plug of the outer sleeve and the base plate of the hydraulic support. The sleeve of the inner sleeve is placed between the ring, on the lower part of the inner sleeve, and the thrust bearing. O-rings are arranged in groups on the inner surface in the lower part of the outer sleeve and on the outer surface in the upper part of the inner sleeve. The thrust bearing is made in the form of a hollow cylinder and a flat ring placed on the bottom of the inner sleeve. The base plate has removable lugs placed on its lower surface.

The invention is illustrated by drawings (Fig.1-6).

The movable irrigation device (FIG. 1) consists of a series of interconnected pipe sections 1. Each pipe section 1 includes a pipe section 2 supported by a self-propelled support 3 with a drive 4, and a free end 5 of the pipe 2 (FIGS. 4 and 5). The pipe sections 1 are connected by flexible couplings 6 located at the free end 5 of one pipe section 1 and the pipe section 2 with a self-propelled support 3 of the adjacent pipe section 1. The movable irrigation device has a drive control mechanism for 4 self-propelled supports 3 located at the ends 5 of the pipe sections 1 s self-propelled supports 3 and containing switches 7 (figure 2 and 3). Each switch 7 is connected through a sensing element to the actuators 4 of the self-propelled supports 3 and perceiving angular movements of the pipe sections 1.

The irrigated field of a rectangular configuration (figure 1) is equipped with two parallel laid water pipes 8 and 9 of the closed irrigation network. Water pipelines 8 and 9 are laid in a ditch and filled with a layer of soil. Water pipelines 8 and 9 do not impede the movement of agricultural tillage, sowing and harvesting transport units. Water pipelines 8 and 9 of the closed irrigation network are located along the long sides of the irrigated field.

Above the soil surface (figure 3) at a height of 0.2-0.3 m stands a hydrant 10 with a ball valve 11 connected to a water supply pipe 8 (9) of a closed irrigation network.

The hydrants 10 in the water supply pipe 8 are offset from the hydrants 10 in the water supply pipe 9 by half a step t between them (Fig. 1).

The last pipe section 1 from an interconnected series of pipe sections 1 is equipped with an additional supporting self-propelled support 12 with drive 4 (figure 1). Thus, the movable irrigation device shown in FIG. 1 has twelve identical pipe sections 1 in design and twelve identical self-propelled supports 3, as well as one additional supporting self-propelled support 12.

Each extreme pipe section 1 (Figs. 1, 2, and 3) has a water intake device 13, periodically hydraulically connected to the hydrants 10 of the first, second, third, and subsequent positions on the water supply pipe 8 (9) of the closed irrigation network. When the process is carried out with a mobile irrigation device, one water intake device 13 at the end 5 of the pipe section 1 is brought into the transport position (FIG. 2), and the other water intake device at the other end 5 of the extreme pipe section 1 is set to the working position (FIG. 3).

Each water intake device 13 (FIGS. 2 and 3) at the extreme pipe section 1 is placed at the end of the pipe 2 by means of a tee 14. The vertical branch 15 of the tee 14 is equipped with a ball valve 16. A ball valve 16 is connected to a set of telescopic pipes 17, 18 and 19. The lower the end of the outer telescopic tube 19 by means of an elastic cylindrical sleeve 20 is connected to a rotary threaded sleeve 21.

The upper end of the inner telescopic tube 17 by elastic elements 22 is additionally connected with a rotary threaded sleeve 21.

Each elastic element 22 in the form of a screw tension spring with screw plugs at the ends is fixed by means of fastening 23 on the flat rings 24 and 25. Ring 24 is freely placed on the upper end of the inner telescopic pipe 17 of the intake device 13. Ring 25 is mounted on the rotary threaded sleeve 21 with the possibility angular displacement around the vertical axis of symmetry of the intake device 13.

The axial movements of the flat rings 24 and 25 on the inner telescopic tube 17 and the rotary threaded sleeve 21 are limited by stops 26, 27 and 28 in the form of rings of square or rectangular sections. The stops 26, 27 and 28 are welded to the inner telescopic tube 17 and the rotary threaded sleeve 21, respectively.

The elastic cylindrical sleeve 20 by means of clamps 29 is fixed on the lower end of the outer telescopic tube 19 and the transition part of the rotary threaded sleeve 21. The rotary threaded sleeve 21 is provided with control knobs 30.

Each telescopic pipe 17, 18 and 19 has a seal and eliminates the flow of irrigation water at a pressure in the water supply network of 0.10 ÷ 0.12 MPa (10 ÷ 12 kgf / cm ² ).

A rotary threaded sleeve 21, an elastic cylindrical sleeve 20 and an external telescopic tube 19, as a single prefabricated structural unit, is provided with the ability to rotate around a vertical axis of symmetry of the intake device 13.

Each rotary threaded sleeve 21 of the intake device 13 has the possibility of threaded pairing with a transition element in the form of a threaded sleeve 31 (Fig. 3) placed on the hydrant 10 by means of a ball valve 11. Instead of threaded sleeves 21 and 31, the detachable connection can be made in the form of boiler or other grooves that exclude water leakage (or performed similarly to fire hose joints).

Each switch 7 (Fig.2 and 3), perceiving the angular displacement of the pipe sections 1, is located at the end of the horizontal branch of the tee 14 and has the ability to contact with the benchmarks 32 (Fig.3). Each benchmark 32 is installed in close proximity to the hydrant 10 installed on the water supply pipe 8 (9).

The elastic cylindrical sleeve 20 compensates for all inaccuracies in the placement of the vertical branch 15 of the tee 14 above the threaded sleeve 31 mounted on the ball valve 11 of the hydrant 10 (figure 3).

Telescopic pipes 17, 18 and 19 allow a wide range of placement of the end 5 of the pipe 2 above the cut of the threaded sleeve 31 of the hydrant 10 and this provides the possibility of a reliable connection of the hydrant 10 for supplying irrigation water to the pipe 2 of the pipe section 1.

Each extreme supporting self-propelled bearing 3 (12) with a drive 4 is equipped with a hydraulic support 33 (Fig.4-6). The hydraulic support 33 is mounted opposite to the gear motor of the drive 4 on the supporting beam 34 between the drive support wheels 35.

Each hydraulic support 33 has a power drive. It is made in the form of two mating outer sleeves 36 and inner sleeves 37. The outer sleeves 36 are fastened by brackets 38, 39 and 40 to the support beam 34 of the self-propelled support 3. The other inner sleeves 37 have a spherical thrust bearing 41 in the form of a biconvex lens. A spherical thrust bearing 41 is placed between the latch 42 of the spherical thrust bearing 41 and the base plate 43. The axial movement of the inner sleeve 37 into the cavity of the outer sleeve 36 is limited by stops 44 in the form of a ring on the lower outer part of the inner sleeve 37. The maximum displacement of the outer and inner sleeves 36 and 37 is limited by the latch 45 in the form of a rope. The ends of the rope are sealed in the threaded rods 46 and 47. The rods 45 and 47 of the latch 45 are located on the top cap 48, mounted on the end of the outer sleeve 36, and on the bottom plug 49, mounted on the end of the inner sleeve 37.

Between the upper plug 48 and the support plate 43 of the hydraulic support 33, a return mechanism 50 of the inner sleeve 37 is placed in the cavity of the outer sleeve 36.

The specified cavity of the sleeves 36 and 37 through the valve 51 and the sleeve 52 are hydraulically connected to the cavity of the pipe 2 of the pipe section 1 of the extreme supporting self-propelled bearings 3 (12).

The cavity of the inner sleeve 37 is connected via a pipe 53 and a valve 54 with the atmosphere, designed to release water from the hydraulic support 33.

The mechanism 50 for returning the inner sleeve 37 to the cavity of the outer sleeve 36 is made in the form of a package of cylindrical twisted tension springs.

The ends of the tension springs by means of threaded plugs and fastening means 55 are placed around the perimeter of the upper plug 48 of the outer sleeve 36 and the base plate 43 of the hydraulic support 33.

The pipe 53 of the inner sleeve 37 is placed between the stops 44 in the form of a ring on the bottom of the inner sleeve 37 and the latch 42 of the spherical thrust bearing 41. The latch 42 of the spherical thrust bearing 41 is made in the form of a hollow cylinder and a flat ring as a cap 49 at the end of the inner sleeve 37.

O-rings 56 are arranged in groups on the inner surface in the lower part of the outer sleeve 36 and on the outer surface in the upper part of the inner sleeve 37.

The base plate 43 has detachable lugs placed in the holes 57 (Fig.6) on its lower surface. Each lug can be made in the form of a pin with a threaded shank.

Mobile irrigation device operates as follows.

Initially, the left water intake device 13 is placed above the hydrant 10 of the water supply pipe 9 (FIGS. 3 and 1). Next, the operator servicing the movable irrigation device removes the cover from the threaded sleeve 31 located on the ball valve 11. Using the control sticks 30, overcoming the elastic forces of the elements 22, the threaded sleeve 21 is moved down to the position shown in Fig. 3. The elastic cylindrical sleeve 20 together with telescopic pipes 17, 18 and 19 allows the threaded sleeve 21 to be combined with the threaded sleeve 31 and the control knobs 21 to smoothly rotate the external and internal threads to full contact. Due to the sealing rings of the cavity of the threaded sleeve 21, a tight contact of the bushings 21 and 31 is created, eliminating the flow of irrigation water. Then, the operator turns the handles of the ball valve 16 and the ball valve 11. Sequentially pressurized water from the water supply pipe 9 of the closed irrigation network through the hydrant riser 10, ball valve 11, threaded sleeves 31 and 32, and the flexible cylindrical sleeve 20 enters the telescopic pipes 17, 18 and 19, and then through a ball valve 16, into a vertical branch 15 of the tee 14. From the tee 14, water flows into the pipe 2 of each pipe section 1. When reaching the end 5 of the pipe 2, water enters the tee 14 at the end 5 of an additional self-propelled th support 12 with the open ball valve 16 (figure 2). Water, mineral litter, suspended matter, rust through telescopic pipes 17, 18 and 19, the coupling 20 and the sleeve 21 are discharged to the surface of the irrigated field outside the water supply pipe 8 of the closed irrigation network. Next, the operator closes the ball valve 16 (Fig. 2), then the actuator 4 of all the supporting self-propelled bearings 3 are electrically connected via a cable to the connector installed next to the hydrant 10. Then the operator takes the switch 7 back, including the actuators 4 in operation.

Prior to the inclusion of the actuators 4, the operator of the leftmost supporting self-propelled support 3 (Figs. 1 and 4) is brought into a fixed, suspended position, raising it with a hydraulic support 33 above the surface of the irrigated field. In this case, the leftmost supporting self-propelled support 3 becomes a fixed support installed next to the hydrant 10 on the water supply pipe 9 of the closed irrigation network.

When the valve 51 is open, water from the pipe 2 under pressure along the sleeve 52 enters the cavity of the inner sleeve 37. The valve 54 on the pipe 53 should be partially closed. Air from the cavity of the inner sleeve 37 is vented to the atmosphere. Next, the valve 54 is completely closed. When water is applied to the inner surface of the plug 48, the inner sleeve 37 is squeezed out of the cavity of the outer sleeve 36. The stop 44, the latch 42, the spherical thrust bearing 41 and the support plate 43 together with the lower turns of the elastic elements of the return mechanism 50 move towards the field surface. In contact with the surface of the field, the base plate 43, the spherical thrust bearing 41, the latch 42, the lower plug 48 and the inner sleeve 37 become stationary. The irrigation water entering the cavity of the outer sleeve 36 lifts through the brackets 38, 39 and 40 the support beam 34 of the left extreme supporting self-propelled support 3. The drive support wheels 35 are detached from the field surface (FIGS. 5 and 4). Then, the valve 51 on the upper plug 48 is closed.

With a low bearing capacity of the irrigated field soil and high soil moisture on the base plate 43, lugs are placed that exclude the displacement of the extreme self-propelled support 3 when other self-propelled supports move along arcs of different-sized circles (Fig. 1).

When the actuators 4 are turned on, the mobile irrigation device conducts sector-specific irrigation with sprinkler devices mounted on pipes 2 with a given step.

When moving the extreme pipe section 1 along an arc of a circle, the additional supporting self-propelled support 12 of the end 5 of the pipe 2 with the tee 14, thanks to the switch 7, reaches the benchmark 32 installed next to the hydrant 10 of the water supply pipe 8 of the closed irrigation network. When reaching the benchmark 32, the lever of the switch 7 electrically disconnects the actuators 4 supporting self-propelled supports 3.

The water intake device 13 at the end 5 of the pipe 2 of the additional supporting self-propelled support 12 from the transport position (figure 2) is brought into the working position (figure 3). The intake device 13 at the end 5 of the pipe 2 of the left extreme support self-propelled support 3 is brought into the transport position.

Further, an additional supporting self-propelled support 12 is brought into a stationary position by lifting it with a hydraulic support 33 above the ground when the base plate 43 is in contact with the field surface.

When the interconnected irrigation devices are turned around the hydrant 10 on the water supply pipe 8, the right (left) extreme additional supporting self-propelled support 12 due to the spherical thrust bearing 41 when the hydraulic support 33 is brought into working position rotates on the base plate 43 with minimal resistance, while maintaining the equilibrium shape due to the shape of the pipe 2 position.

The hydraulic support 33 on the leftmost supporting self-propelled support 3 from the working position (figure 4) is transferred to the transport position (figure 5) as follows. When the valve 51 is closed, the valve 54 is completely opened on the nozzle 53. Under the influence of the weight of the leftmost self-propelled support 3 by the outer sleeve 36, water is squeezed out of the cavities of the sleeves 36 and 37 through the nozzle 53. The carrier beam 34 together with the drive support wheels 35 is lowered down to contact with the surface of the field. Further, under the influence of the elastic forces of the stretched springs of the return mechanism 50, the base plate, through the spherical thrust bearing 41, biases the lower plug 49 together with the inner sleeve 37 to the transport position. Water from the cavity of the inner sleeve 37 through the pipe 53 with the open valve 54 spills out. The base plate 43 together with the spherical thrust bearing 41 and its latch 42 are brought into the transport position (Fig.5 and 6).

When the movable irrigation device reaches the edge of the short side of the field, the reverse drive is switched on by changing the phases in the electric network. The drive wheels 35 of the supporting self-propelled supports 3 move along the arc prints on the surface of the irrigated field, made during the first (direct) passage of the irrigation device.

A mobile irrigation device will allow to irrigate rectangular fields with multi-support circular sprinklers, reduce rutting under drive wheels, reduce capital costs for the construction of an irrigation system, and simplify maintenance of the entire system.
