Abstract

The invention relates to agriculture and can be used on self-propelled multi-support sprinkler machines. The purpose of the invention is to increase the reliability of operation by providing a stop-start mode of movement of the carts. The multi-bearing circular sprinkler includes a fixed support, a water supply pipe with sprinklers, running trolleys 5 with hydraulic drive and an automatic speed control system for the movement of carts. The system of automatic control of the speed of movement of the carts has a valve 11, a pressure lever 12, a control rod 4 and a regulating one. kernel. The regulating rod is made divided into a figured slider 13 and a rectilinear control part 18. The figure slider is equipped with stops 14 and 15 and the course limiters § 16 and 17. The linear control part 18 is equipped with stops 19 and 20.. The boundaries 16 and 17, and stops 19 and 20 are installed with the possibility of interaction with the rocker 22 with the trigger spring 23. 2 Il. (L

The invention relates to agriculture and can be used on self-propelled multi-support circular irrigation machines.

The purpose of the invention is to increase the reliability of operation by providing a stop-start mode of movement of the carts.

Fig. 1 schematically shows the proposed pivot sprinkler, view in plan; in fig. 2 is a diagram of the hydraulic drive of the undercarriage with a speed-motion control system.

The circular sprinkler is a sprinkler of water pipe 5, which is.

The bridge consists of a fixed support 1, a water supply pipeline 2 with sprinklers 3, with which rigidly attached control cabins 4 are installed on the undercarriage 5, on which 20 hydraulic actuators with supply hoses 6 and 7 are fixed, with an air damper 8 and a fluid supply mechanism 9 to the hydraulic cylinder 10, and a system for automatically controlling the speed of 25 movements of trolleys, including a control valve 11, a pressure lever 12, a figured slider 13 with stops 14 and 15 and limiters 16 and a slide. The linear control ZO control part 18 of the control rod is made with stops 19 and 20 and is connected to the control 4 rods through the collar 21. Between the lugs 14 and 15 of the figured slider 13, 19 and 20 of the control part 18 of the regulating rod, a rocker arm 22 is located, which is connected to the trigger spring 23 and is mounted on the axis 24. The figure slider 13 has a smooth groove for fixing its position corresponding to the fully open regulating the valve 11. Between the limiters 16 and 17 of the stroke is installed roller 25.

bending, at the place of attachment to the next carriage, through a control rod of this carriage activates its speed control system. The launch and movement of all undercarriage is similarly carried out.

When any self-propelled trolley runs forward, the control rod 4 moves the control part of the regulating rod 18 to the rear. The stop 19 presses the rocker 22, after passing through the dead zone under the action of the trigger spring 23, the rocker 22 abruptly presses the stop 15 of the figured slider 13 and moves it all the way to the limiter 16 into the roller 25. The pressure lever 12 releases the figured slider 13 and adjusts valve 11 closes.

, The supply of fluid to the hydraulic drive carriage is stopped and the carriage stops. When running ahead of two neighboring carts, a lagging carriage is launched. In this way, the line of the sprinkler is kept.

Smoothing the pulsation and pressure of the water when switching the water supply to the hydro-smoothing of the pulsation and pressure of the water when switching the water supply to the hydraulic dozhdevalnaya circular de-dz cylinder machine, when opening and closing, works as follows.

When creating a head in the water supply pipe, the last carriage 5 starts moving at the speed set by the operator. The water supply pipe 2, moving together with the last carriage, begins to bend at the attachment point to the next carriage, and the control rods 4 rigidly connected to the pipe 2 move part of the control rod 18 forward (relative to the movement of the sprinkler). The stop 20 presses the rocker 22 and after passing the wheel 55

the damping valve 11 is due to the air damper 8.

Claims (1)

Invention Formula Multi-support circular sprinkler, including fixed support, Water supply pipe with sprinklers, travel trolleys with hydraulic drive for automatic control of travel speed of trolleys with valve, pressure racer and throttle control. A dowel rod with a rectilinear control part, distinguishing the arrays of the dead zone, under the action of the trigger spring 23, the rocker presses abruptly through the stop 14 on the figured slider 13 and moves it all the way to the limiter 17 to the roller 25. The figured slider 13, moves, acts on the pressure lever 12, which quickly opens the control valve 11. The fluid enters the hydraulic drive. As a result of the action of the hydraulic cylinder 10 through the system of levers 26 and 27 to the wheels 28, the trolley is moved from the driveway, moving forward ABOUT five 0 bending, at the place of attachment to the next carriage, through a control rod of this carriage activates its speed control system. The launch and movement of all undercarriage is similarly carried out. When any self-propelled trolley runs forward, the control rod 4 moves the control part of the regulating rod 18 to the rear. The stop 19 presses the rocker 22, after passing through the dead zone under the action of the trigger spring 23, the rocker 22 abruptly presses the stop 15 of the figured slider 13 and moves it all the way to the limiter 16 into the roller 25. The pressure lever 12 releases the figured slider 13 and adjusts valve 11 closes. , The supply of fluid to the hydraulic drive carriage is stopped and the carriage stops. When running ahead of two neighboring carts, a lagging carriage is launched. In this way, the line of the sprinkler is kept. Smoothing the pulsation and water pressure when switching the water supply to the hydros cylinder, when opening and closing the rap five the damping valve 11 is due to the air damper 8. Invention Formula Multi-support circular sprinkler, including fixed support, Water supply pipe with sprinklers, travel trolleys with hydraulic drive for automatic control of travel speed of trolleys with valve, pressure racer and throttle control. a core with a linear control part, characterized in that, in order to improve reliability by providing a stop-start mode of movement of the carts, the system of automatic control of the speed of movement of the carts is equipped with a rocker with a kurkovy spring, a figured slider and a linear the governing part of the regulator. the rod is installed autonomously and each of them is equipped with two stops installed with the possibility of interaction with the rocker, while the figured slider has two travel stops.  xfk 1
