Srednesrocnye sprinkler apparatus pie action

 

(57) Abstract:

Usage: in the agricultural industry, in particular in the construction of the sprinkler apparatus. The essence of the invention: srednesrocnye sprinkler apparatus pie action includes a housing 1 with a Central shaft, two side of the barrel 2, the arm 4 with a reactive blades 5 at the ends and the bracket 8, is rigidly connected with any rotating part of the apparatus, each end of which is rigidly fixed deflector 9, facing its working surface in the direction opposite to the working surface of the jet vanes. however, the situation of the working surface of the deflector 9 on the bracket 8 can be adjusted vertically up or down, around a vertical, longitudinal arm around him, and the angle of intersection of the working surface of the deflector with the axial line of the nozzle 3, which is the optimal size of the reaction force of the jet on a rotating device using the spring force of the rotation unit. 4 Il.

The invention relates to agriculture, namely, irrigation technology, and can be used in sprinkler systems.

Known srednesrocnye sprinkler apparatus circular steps, including Kah trunk with nozzles, pointing in opposite directions and the rotation unit of the apparatus, consisting of a rocker arm with a reactive blade on one end and a counterweight on the other, a return spring on the rod and two racks mounted on the lateral trunks, limiting the rotation of the rocker arm, perceiving his pulse beats with the range of angle of rotation of the apparatus for 2-4aboutfor each hit, with the angles between the axes of the shafts with the nozzles and horizon within the 30about.

The disadvantage of this apparatus is that the rotation of the device pulses for 2-4aboutis carried out by pushing from the reactive power flow in the blade and through the rocker on its rotating parts and the reciprocating strokes of the rocker arm on the bar, which leads to 180-360 the oscillation device in different directions for each turn, jamming friction (rotary) parts to their rapid deterioration and inability to use such a device, for example, is suspended on the rod. The angle of attachment to the horizon of the apparatus 30aboutthat creates rain, more wind resistance, and this leads to increased losses its entrainment by wind and evaporation. Recoil mechanism of rotation in the result of metal fatigue often prematurely ceases to rotate apparatuses from similar topics the rocker has a reactive blades on both ends, and corners of the nozzles with the horizon are within 5-30about[2]

A significant drawback of this apparatus is its stop (the bounce) in the cause of aging (fatigue) recoil node in turn, weaken the force of impact of the beam on the rack.

The purpose of the invention increase the technical reliability of the device by use of the reactive force of the jet coming under pressure from the nozzles of its attachments.

This objective is achieved in that on one of the rotating parts of the machine, for example the top of the racks node rotation (or lateral trunks) fixed bracket, the second end is outside of the path of rotation of the jet vanes rocker, is at the intersection with the centerline of the nozzle is rigidly fixed deflector facing its working surface at a certain angle to the direction opposite to the working surface of the jet vanes. This deflector has the ability to adjust the vertical position (up-down) longitudinally of the bracket about the axis of the bracket and the angle of intersection of working surface with the axial line of the nozzle, due to nagode the node.

In Fig. 1 shows srednesrocnye sprinkler apparatus, a General view of Fig. 2 is a top view of Fig.3 is an exemplary diagram adjust the position of the deflector of Fig. 4 scheme of the action of reactive forces on the rotation of the device during its operation.

Srednesrocnye sprinkler apparatus pie action includes a housing 1 with a Central shaft inside and elements connected to the armature water conveyance pipeline, stock and two Smoking barrels with 2 nozzles 3, node of rotation of the shafts, consisting of the rocker arm 4 with a reactive blades 5 at the ends, a return spring 6, the two racks 7 stops rotation of the rocker arm, rigidly connected with the side holes 2 and the bracket 8 with the deflectors 9 at the ends rigidly connected with any rotating part of the apparatus, for example, the top of the rack 7 in place OF1or trunks 2 for location A (shown dotted). In this case the angle between the axial line of the nozzle 3 with the horizon is known limits 5.30aboutand the position of the working surface of the deflector 9 on the bracket 8 can be adjusted by moving the deflector vertically up and down, around a vertical, longitudinal arm around its axis and the angle of intersection of the working surface of the deflector with the axial line of the beam, a boat, etc.

In the process (irrigation) water passing through the Central barrel body 1, sidetracks 2, is ejected under pressure jets through nozzles nozzles 3. Jets hit in the profile (working) surface of both reactive blades 5. Blades at the same time deflected clockwise Nl(Fig.4), rotating the arm 4 around the axis of rotation of device 001(at the position of the apparatus by the connection point 0 from the bottom counterclockwise), vzvoda return spring 6, informing both the pulse energy and all other rotating parts in needs no direction. The spring 6 returns the jet vanes 5 in the initial position, the rocker 4 produces operational impact of the reactive force of the spring RAvefrom two sides simultaneously by uprights 7, and at the same time part of the jet nozzles on 3 hits on the working surface of the deflector 9, than creates a reaction force her reflection Rdand apparatus, overcoming the inertial force from the blades of Nlclockwise, under the joint reactive forces RAve+ 2Rdwarranty is rotated by some angle, for example 2-4aboutanticlockwise on the working direction of rotation of appare return the rocker 4 deals another blow to the racks 7 counterclockwise, the deflectors 9 through a bracket 8 help unwinding the spring and the operating cycle of the apparatus is repeated.

The invention can be effectively used in the manufacture of new vehicles and the modernization of all operating, for example by sprinkling machines "Frigate".

SREDNESROCNYE SPRINKLER APPARATUS CIRCULAR STEPS, including a housing with a Central shaft inside and elements connected to the armature water conveyance pipeline, two diametrically spaced side trunk with nozzles, mounted at an angle 5 30oto the horizon, and a host of rotation of the shafts is made in the form of a beam with reactine blades on the ends, return spring and two enclosures limiters rotation of the rocker arm, rigidly connected with the side trunks, characterized in that provided is rigidly fixed on the rotary part of the apparatus of the bracket, the ends of which are located beyond the path of rotation of the jet blades rocker and are in intersection with the centerline of the nozzle orifice is rigidly fixed deflector facing its working surface at an angle in the direction opposite to the working surface of the jet vanes, while the deflector is fortified with vorozole bracket, around him and within the angle formed by the intersection of working surface of the deflector with the axial line of the nozzle.
