(54) ELECTRIC WATER UNIT

CARS

one

The invention relates to agriculture and can be used in irrigation machines operating on open irrigators.

Known intake device of the pumping station, mounted on a tractor through its parallelogram hinge, including a suction device with a cleaning grid 1.

The disadvantages of this device are the need to manually shut off the sprinkler or, with the help of other special means, and the impossibility of water supply when the tractor is located along the sprinkler next to its berm, as well as frequent clogging of the cleaning grid with plant debris and the need to stop the water supply to clean it.

Closest to the proposed intake device irrigation machine, which includes a suction nozzle mounted on the tractor frame and a jumper shield 2.

A disadvantage of this device is the inaccurate overlap of the sprinkler and possible water leaks, which reduces the efficiency of the machine.

2,

The purpose of the invention is to increase work efficiency by ensuring reliable overlap of the irrigator.

This goal is achieved by the fact that the device is connected to the tractor frame by means of a telescopic boom with control hydraulic cylinders and is provided with a guide frame that repeats the profile of the shield and mounted on the boom by means of spring-loaded racks and a two-armed lever fixed to them, connected to the boom by a horizontal ball. .

15 The water intake device is mounted on the tractor of the irrigation machine, which includes a pumping unit, consisting of an axial pump 1 with a vertical shaft 2Q of the impeller and gearboxes 2 and 3.

The water intake device includes a bridge 4, a guide frame 5 with a net 6 connected to the frame 5 hinges 7, and connected to a tractor of an irrigation machine with a telescopic boom 8 mounted on the frame 9 between the guides 10. The power cylinder 11 is designed for raising and lowering boom, power cylinder 12 - to change its length. The reflective shield 13 is located under the suction nozzle 14 with a cleaning grid. The telescopic articulated shaft 15 and the coupling 16 are connected to the PTO 17 of the tractor 18 and to the gearboxes. The boom rests on the axis 19, and the reflector shield on the hinge supports 20. The guide frame 5 is fixed to the boom 8 by means of spring-loaded racks 21 and a double-arm lever rigidly connected to them, connected to the boom 8 by a horizontal hinge 23.

The intake device operates as follows.

The tractor 18 is installed along the sprinkler so that the pump 1 can be lowered at the center of the sprinkler. The power cylinder 11 lowers the boom 8 and follows whether the pump 1 falls into the middle of the irrigator. If pump 1 falls into the middle of the sprinkler, the lowering is performed completely and switching on the drive starts the water supply, and if pump 1 does not fall into the middle (control is carried out on the telescopic frame 5) the sprinkler stops lowering when the telescopic frame 5 is at a low height wall irrigation. Power cylinder 12 conducts a coarse adjustment of the length of the boom 8, and then lower the pump 1 completely and begin water supply.

In all cases, before the boom 8 is fully lowered into the irrigator, the power cylinder 12 must be placed in the floating position. This is necessary for the self-installation of pump 1 and lintel 4 in the recess of the irrigator by means of the telescopic frame 5. When self-installing, the automatic extension or shortening of the boom 8 is performed by the action of the reactive force of the irrigator wall on the lateral support surface of the telescopic frame 5. When the tractor is located across the irrigator, the pump is lowered In the middle of the sprinkler, the tractor is fed backward or forward. In the transport position of the water intake device, the support surface of the frame 5 under the action of the spring-loaded racks 21 is lowered below the edge of the shield-lintel 4. This is necessary to ensure that the lintel is tapped into both slopes of the irrigator to the same depth.

When lowering the boom 8, the walls of the irrigator must first touch the supporting parts of the frame 5 in order to slide along them (the walls) and bring the shield-jumper 4 (by means of the reflective shield 13) to the middle

sprinkler. This achieves the location of the lower edge of the lintel above the sprinkler bottom (symmetrically). After that, the vertical (or other necessary) position of the uprights 21 is established by lengthening

or shortening the boom 8 with a hydraulic cylinder 12.

If the lower part of the frame 5 is at or above the lower edge of the shield-lintel 4, then the shield-lintel will first touch the wall of the irrigator, bump into it and there will be no quality overlap (i.e., centralization will not be ensured).

Upon further lowering of the boom under the action of the force of gravity (weight) of components and parts mounted on it, and

the cylinder 11 springs 21 are compressed and the edges of the shield 4 are evenly cut into the bottom and walls of the irrigator. In this way, a good overlap of the irrigator is provided.

 water intake from various channels

The depths of the jumper board 4 and the frame 5 are attached to the uprights 21 at different heights, but in all cases the suction nozzle 14 with the net is completely below the water spreader in the irrigator.

The use of the proposed water intake device increases labor productivity by 10-12% and reduces unproductive water losses daily with two-shift operation by 400-500 cubic meters. m at a working consumption of 200-250 l / s, improves working conditions, since the removal of garbage from the grid is performed above the water without stopping the water supply.
