Description

The invention relates to agriculture, in particular to irrigation technology.

The purpose of the invention is to improve the quality of irrigation by ensuring a stable rotation of the opening in the irrigation process and reducing wind loads on them during the non-working period.

1 schematically shows a rain-forming device, side view; Figure 2 shows a sprinkler tip with a lever and a load; 3, the end sprinkler head with a weather vane.

The rain-forming device consists of a hinge 1, directly opening 2, end sprinkler nozzles 3 and 4 on hinges 5 and 6 with springs 7 and 8, with a tip nozzle 3 a vane 9 is rigidly connected, and the torch axis is crossed with a turning axis of the nozzle . The nozzle 4 is rigidly connected to the lever 10, on which the load 11 and the wind balancer 12 are placed. The sprinkler nozzles 13 are installed along the entire length of the wings 2. The initial position of the lever 10 is fixed by the abutment 14, the stroke of the coaxial vane

and limited to stops

sets 90

15 and 16..

During the non-working period, there is no water in the wing 2 and the nozzles 3 and 4. Under the action of the springs 7 and 8 and the stops 14 and 15 are in the initial position, shown by a solid line in Figures 2 and 3, the Weather Vane 9 takes up a vertical position and reacts to the wind The orientation of the wing 2 is parallel to its direction.

The rain-forming device operates as follows.

Water distributed over the wing

2, fed to sprinkler heads

3.4 and 13 that spray it

in the zone of action of the rain-forming device. Due to the intersection of the axis of the spray torch rain with the axis of the hinge, the sprinkler head 3 with the weather vane 9, under the action of the reactive moment created by the head 3, rotates in the hinge 3 on the SP under the stop 16 (FIG. 3, dashed line). Reactive moment from the sprinkler nozzle 4 begins to rotate the opening of the 2 in the hinge 1, having a maximum value.

Under the action of centrifugal force, the load 11 on the lever 10, overcoming the elasticity of the spring 8, turns

the sprinkler head 4 in the hinge 6 and thereby reduces the reactive moment, and therefore the speed of rotation of the opener 2. Spring 8 tries to bring the head 4 to its original position

and to increase the moment and at a fixed position of the load 11 on the lever 10, a corresponding stable rotational speed of the opening 2 is generated (Fig. 2, dashed line). When working

in windy weather, wind balancer 12 eliminates the effect of wind on load 11, and hence on the stability of the rotational speed of the opener 2.

When the water supply is cut off, the sprinkler heads 3 and 4 under the action of the springs 7 and 8 occupy the initial positions, limited by the stops 14 and 15, and the vane 9 is installed vertically.

Claims (1)

Formula image shadows The rain-forming device, which includes sprinkling nozzles located on rotating wings, is mainly due to the fact that, in order to improve the quality of irrigation by ensuring stable rotation of the opener during the irrigation process and reducing wind loads on them during off-hours, the sprinkler nozzles located at the ends of the openings, mounted on spring-loaded hinges, one with rotatably open parallel to the plane of rotation, and the other perpendicular to it, while the first nozzle is equipped with kinematically a lever with a load and a wind balancer connected with it, and the second one has a vane with a horizontal axis of rotation. 15 Editor P.Geershi Compiled by M.Hrabov Tehred M.Didyk Order 4537/2 Circulation 627 Subscription VNIIPI USSR State Committee for inventions and discoveries 113035, Moscow, Zh-35, Raushsk nab., 4/5 Production and printing company, Uzhgorod, st.
