Description

The invention relates to agriculture and can be used in irrigation equipment, namely on front-end irrigation machines.

Known sprinkler machine type "Dnieper", consisting of carts with electric drive, on which there is a water supply pipeline with sprinklers and a water intake unit (Sapunkov A.P. Mechanization of irrigation by sprinkling. - M .: Kolos, 1984, 271 p.).

The disadvantages of DM Dnepr are the complexity of control during the driving of cars, since there is no system of automatic control of movement at the heading; low uniformity of irrigation in the wind; insufficient reliability of electric drives of carts operating in a humid environment after irrigation, and also the need for an electric mobile station on a tractor.

As a prototype of the invention, a front-acting irrigation machine was selected, in which all the mechanisms of movement and regulation work due to the energy of the water pressure received from the pressure pipe of the irrigation network through a flexible sleeve, and the machine moves at a given rate by the operator in manual mode (RF Patent No. 2378824. Sprinkling machine. A01G 25/09, published on January 20, 2010. Bull No. 2).

The disadvantage of this machine is its low productivity, since one trolley ensures the pulling of a pressure flexible hose with a water flow rate of 25 ... 30 l / s, as well as the complexity of correction when moving along the course with manual control, as a result, wide ruts are formed on the field, at which agricultural plants.

An object of the invention is to increase labor productivity, as well as automation of the movement control of the sprinkler at a given rate.

This task is achieved by the fact that a driving support is introduced into the machine, consisting of two trolleys with hydraulic actuators equipped with shut-off valves, a directional control system is fixed on the frame of the driving trolley in direction with a copier, executive valves and a slider of a tracking device moving in the guide furrow, and a water pipe between the carriages of the leading support is mounted a drum (with the possibility of rotation) with a flexible pressure sleeve, and the extreme carriages of the machine are equipped with two direct and reverse speed controllers the course of travel, which are connected by cables to the overhangs of the frames of the last but one trolley, while the shut-off valves are hydraulically connected to the executive valves, which are controlled by a copier of the heading control system.

The invention is illustrated by drawings.

Figure 1 shows a General view of the sprinkler machine from the side.

Figure 2 shows a leading support with a heading control system.

Figure 3 shows a sprinkler machine top view.

Figure 4 shows the hydraulic control circuit of the machine.

Figure 5 shows the technological scheme of irrigation irrigation machine.

The sprinkler machine (Fig. 1) consists of a water supply pipe 1 with sprinklers 2 mounted on a leading support 3, intermediate 4 and extreme 5 trolleys. The leading support 3 consists of two driving trolleys 6 and 7, between which a drum 9 with a flexible sleeve 10 is placed on the pipe 8. The trolleys 6 and 7 of the leading bearing 3, the intermediate 4 and extreme 5 trolleys are equipped with hydraulic actuators 11 that provide reverse movement of the machine - forward and back.

The cart 6 of the leading support 3 (Fig.2) is equipped with a control system for movement along the course 12, which includes an articulated follower 13 mounted on the frame and mounted above the guide groove 14. The follower 13 is connected by a link 15 with a copier 16, which interacts with executive valves 17 and 18. Hydraulic tubes 19 and 20 connect the actuating valves 17 and 18 to the water supply pipe 1, and the tubes 21 and 22 connect the same actuating valves to the shut-off valves 23 and 24 of the carts 6 and 7. The extreme carts 5 (Fig. 3) sprinkler mash The others are equipped with speed controllers 25 and 26 of the forward and reverse motion, which are connected with the help of the cables 27 and 28 to the overhangs of the frames of the penultimate trucks 4.

To synchronize the speed of movement of the carts 6 and 7 of the leading support 3, the hydraulic actuators 11 have one inlet sleeve with a speed control valve 29 (figure 2), which allows you to change the speed of its movement. The flexible sleeve 10 through the column 30 is connected to the hydrant 31 (Fig.1) of a closed irrigation network. The sprinkler machine is equipped with an emergency protection system, which includes a hydraulic tube 32 (FIGS. 4 and 2) with shut-off valves 33 of the trolleys 6, 7, 5 and executive valves 34 of the speed controllers 24 and 25. The intermediate carts 4 of the sprinkler machine are also equipped with speed controllers 24 and 25 forward and reverse.

At the edge of the field, a stop device 35 is installed (Fig. 5), which acts on the executive valve 36 for emergency protection mounted on the frame of the trolley 6. When the car hits the stop device 35, the actuator valve 36 is depressurized and the machine stops (Fig. 2). The copier 16 interacts with the executive valves 17 and 18 through the pendulums 37 and 38. The follower 13 moves the slider 39 in the guide groove 14.

Sprinkler machine operates as follows.

In the initial position, the sprinkler is installed at the beginning of the irrigated area (figure 5). A flexible sleeve 10 (Fig. 1) is wound on a drum 9 and, through a column 30, is connected to a hydrant 31 of a closed irrigation network. When the latter is opened, water under pressure enters through the drum 9 into the water supply pipe 1 of the machine and then to the sprinklers 2, which spray irrigation water into the field. Further, after the opening of the setpoint valve 29 (Figs. 2, 4), water under pressure enters the hydraulic actuators 11, providing movement of the carts 4, 5, 6 and 7, both forward and backward.

When the machine moves forward, the flexible sleeve 10 is unwound from the drum 9 and placed on the field. When the leading support 3 is moving, the slider 39 of the motion control system along the course 12 moves along the guide furrow 14 (FIG. 2). In case the drive carriage 6 deviates to the left, the copier 16 is turned in the direction of travel, which acts on the pendulum 37 of the executive valve 17. When the executive valve 17 is depressurized, the shut-off valve 23 stops the water supply to the hydraulic drive 11 of the drive carriage 6. The latter stops, and the carriage 7 continues to move with normal speed until the tracking device 13 becomes in a normal position and both carts 6 and 7 begin synchronous movement in a given direction.

In case of deviation of the driving carriage 6, the copier 16 is turned to the right in the direction of travel, which acts on the pendulum 38 of the executive valve 18. When the executive valve 18 is depressurized, the shut-off valve 24 stops the water supply to the hydraulic drive 11 of the carriage 7. The latter stops, and the driving carriage 6 continues to move up to as long as the tracking device 13 does not become in a normal position and both carts 6 and 7 begin synchronous movement parallel to a given line of direction of movement (figure 2).

In the event of failure and stopping of any trolley (4, 5, 6, 7) of the machine, the executive valve 34 (Fig. 4) of the emergency protection system activates, which closes the shut-off valves 33 and stops the movement of the trolleys 6 and 7 and the extreme trolleys 5. The machine stops, and its breakdown is excluded.

After moving the sprinkler to the edge of the field (Fig. 5), the machine is stopped by a stop device 35, which, when the executive valve 36 is depressurized (Fig. 2) of emergency protection, simultaneously turns off the hydraulic actuators 11 of the bogies 6, 7 and 5.

After that, the operator closes the hydrant 31 (figure 1), and the water supply to the sprinkler is stopped. Next, the operator disconnects the pressure sleeve 10, drains water from it and wraps it on the drum 9. The machine is transported to a neighboring position (figure 5). The hydraulic drives of the bogies 4, 5, 6 and 7 are rearranged to move “backward”. Subsequently, the operator connects the pressure hose 10 to the hydrant 31 of the closed irrigation network and, opening the hydrant, delivers water to the machine. The machine begins to move in the opposite direction (figure 5).

The straightness of the water supply pipe 1 is provided by the forward and reverse 25 speed controllers of the intermediate trolleys 4. To ensure the straightness of movement, the extreme trolleys 5 are equipped with speed regulators 25 and 26. When the extreme trolley 5 lags (runs down) relative to the last but one trolley 4, the cable 27 and 28 move, and the speed controller increases (decreases) the speed of movement. This ensures the straightness of the pipeline 1 sprinkler machine.

The advantage of the proposed sprinkler machine is that the leading support with two trolleys provides work with a large pressure hose with a diameter of up to 150 mm, which allows to increase water consumption up to 50 ... 60 l / s and productivity in comparison with Frigate-FSh, “ Kuban-FSh "and" Volzhanka ".

Heading control system ensures stable frontal movement of the machine in automatic mode and reduces trampling of agricultural plants.

The supply of the extreme carriage with forward and reverse speed controllers ensures the straightness of the pipeline relative to the penultimate carriage and the leading support.

The proposed machine provides irrigation in motion, while increasing the uniformity and quality of irrigation compared to machines Volzhanka, Dnepr (positional irrigation) and DM Fregat (serial circular irrigation).

The proposed machine provides irrigation of rectangular sections in frontal traffic with a high value of the coefficient of land use of 0.96 ... 0.98 instead of 0.81 ... 0.83, typical for circular machines of the type "Frigate".
