Sprinkling machine front steps

 

(57) Abstract:

Use: agricultural machinery, sprinkler front steps, for irrigation of agricultural crops on heavy soils with low permeability. The inventive sprinkling machine front steps include water conveyance pipeline 1, wing 2 with mounted deflector nozzles, and at one end otkrylas installed deflector nozzles circular steps 3 and at the other end of sectoral actions 4, and they are located in a checkerboard pattern. This arrangement deflector nozzles pie and pie action provides the largest area for simultaneous capture the rain, and the lowest intensity of rain that allows you to issue the irrigation rate for a single pass of the machine. 1 Il.

The invention relates to agricultural machinery, namely sprinkling machines, front steps, and can be used for irrigation of agricultural crops on heavy soils with low permeability.

Known multisupport sprinkling machine front steps "Kuban", producing irrigation in motion, on the final action [1]

Known sprinkling machine with the installation of the deflector nozzles circular actions in two lines, for example dual console sprinkling unit DDA-100MA [1]

The disadvantage of this scheme of arrangement of nozzles is large, the actual intensity of rain that on heavy soils with low permeability does not allow to issue the irrigation rate for a single pass of the machine.

Closest to the proposed technical essence and the achieved effect is sprinkling machine DM-20 [2] deflection of the circular nozzle which is installed in three lines, one line deflection nozzles installed on the water conveyance pipeline, and two on the wing.

The disadvantage of this machine is also unsatisfactory high intensity rain when working sprinkling machines on heavy soils with low permeability.

To remedy this allows the proposed sprinkling machine front steps, including power tubing and wing mounted deflector nozzles, which on one end of the wing installed deflector nozzles circular steps, and at the other end of sectoral actions, and those and drawableshape simultaneous capture rain and is calculated by the formula:

< / BR>
where Q is the water flow rate, l/s;

l is the length of the seizure, m;

In width.

To achieve the intensity of the rain, the corresponding speed of absorption of heavy soils, without reducing the output of the machine is possible only by increasing simultaneously irrigated area.

The proposed scheme of rational location of the deflector nozzles circular and sector actions can increase the area of simultaneous capture of rain, and therefore, reduce the intensity and improve the uniformity of the distribution of rain on the area of irrigation due to the fact that at the same flow rate range from deflection nozzles sectoral actions more than the deflector nozzles of circular steps.

The drawing shows the circuit arrangement of nozzles on the width of the machine.

On water conveyance pipeline 1 with a certain step perpendicular to the axis installed the wing 2. On one end of the wing 2 is installed deflector nozzle circular steps 3 and at the other end of the deflector nozzle sector steps 4, spaced lines in a checkerboard pattern.

Water under pressure from the water supply pipe 1 enters the wing 2, and then it the form of the irrigated area in the form of a circle, and nozzles sectoral actions the shape close to the oval, which increases the length of the capture B4, and hence simultaneously irrigated area along the length mototransportnye pipeline 1, which is illustrated an example of a different arrangement of the deflector nozzles on dual console unit DDA-100MA (see table).

Analysis of distribution of rain shows that the largest area of simultaneous capture of rain, and the lowest intensity of rain provides the proposed scheme of arrangement deflector nozzles pie and pie action.

SPRINKLING MACHINE FRONT STEPS, including power piping and installed the wing with scanning nozzles, wherein one end of each wing installed deflector nozzle circular steps, and at the other end of sectoral actions, and the nozzle is circular and sector actions are staggered.
