Description

[Detailed description of the invention] The present invention is a rotary water sprinkler in which the water spray beak appears and disappears from the ground together with the lid due to water supply water pressure, and sprinkles water while rotating. The outer ring body is divided into a fixed outer ring body and a disc lid that is movable up and down. The disc cover is fixed on the cover support ring which is rotatably attached to the upper support shaft via a Teflon sliding washer, and it is inserted into the center of the bottom of the head box where the piston tube slides through. This invention relates to an automatic rising rotary water sprinkler in which a seal backing and an erosion control dust seal are interposed in a screw thread with a cap nut.

In the illustrated embodiment, a water conduit pipe is rotatably fitted to the mounting pipe a screwed and fixed to the upper end socket portion 17 of the piston pipe 10, and a water spout C screwed and fixed onto the water conduit pipe is rotatably fitted. A water spray beak d is screwed on one side, and a water spray pipe e is provided diagonally upward on the other side, and a water spray beak e' is screwed onto the tip thereof.

On the water spout C, a swing arm h having a water reaction plate f facing the water spout d at one end and a balance weight g at the other end is rotatably supported by a support shaft i. The upper support shaft 11 of i is supported by the left and right shock rods J1゜j2 extending from the support shaft 11 to the body of the water spout C in a fork shape, and in the flat case, from the swing arm h to the upper support shaft 11. Due to the attached spring S, the water reaction plate f side of the swing arm is attached to one impact rod j1 at a position opposite to the water discharge beak d, and the balance weight g side of the swing arm is attached to the other impact rod j2. They are in pressure contact.

The water reaction plate f has an inclined water guiding surface f' and a window f/! and a curved impact surface f/// are provided (see Figure 3).
, the water ejected from the water spout d flows through the slope ′ through the window f //
It collided with the curved impact surface f// and ejected the water force reaction plate f. Due to the reaction of the water force, it resisted the spring S and momentarily separated from the impact rod j1, rotated the swing arm h, and then was displaced. When the water force reaction plate F is released from the water force ejected from the water spray beak, the plate subjected to impact by the restoring force of the compressed spunong S] 1.32 is repeatedly struck, and the impact causes the water spout C to close to the water conduit pipe. Together, they form a so-called rotary water sprinkler 7 that sprinkles water from the water spray pipe e while rotating clockwise around the attachment pipe a.

The above-mentioned information belongs to the conventional knowledge.

Therefore, in the present invention, the lid of the head box 1 that houses the rotary water sprinkler 7 is divided into a flat outer wheel body 4 fixed to the top surface of the head box 1 and a disc lid 8 that is movable up and down. The joint peripheral surfaces of the fixed outer ring body 4 and the rubber cover 6 that covers the disc lid 8 are formed into inverted conical end surfaces 3 and 9 that are in close contact with each other, and are mounted on the upper support shaft part 11 of the rotary water sprinkler. , a presser metal fitting having a lid receiving ring 20 with a step 19 on the inner surface via a Teflon sliding washer 18, a flange 21 that engages with the step 19 of the ring 20, and a support shaft through hole 22 in the center. 23 is fitted and fixed 24, and the lid holder ring 20 is attached to the support shaft i.
The disc lid 8 is fixed 25 on the lid receiving ring 20 so that the disc lid 8 and the rotary water sprinkler 7 do not rotate in synchrony, and the piston pipe 10 is slidably inserted through the pipe. A seal backing 12 and a sand prevention dust seal 13 made of urethane rubber or the like are interposed in a screw 26 protruding from the center of the bottom of the moving head box 1 so as to be adjustable with a cap nut 27, thereby creating a cylinder for sliding the piston pipe for rainwater, earth, sand, etc. This is to prevent intrusion into 11.

In the figure, 2 is the head box flange, 5 is the embedded plate, and 14
15 is a spring, 16 is a head box support tube, 28 and 29 are Teflon washers, 30 is a rubber backing, and 31 is a metal washer.

In the present invention, which is constructed in a diagonal manner, a head box 1 containing a rotary water sprinkler 7 is buried up to the ground surface of a golf course, sports field, etc., and a fixed outer ring body 4 attached to the upper peripheral flange 2 is installed. It is installed so as to be substantially aligned with the ground plane, and when watering, pressurized water is passed into the piston pipe 10 from the water pipe connected to the head box support pipe 16, so that the water pipe is connected to the upper end socket portion 17 of the piston pipe 10. The rotary water sprinkler 7 attached through the spout and the disc cover 8 attached to the top of the sprinkler are extended above the ground, and the water fountain from the water spout d collides with the water reaction plate f, and the restoring action of the spring Impacted rod j1. J 2 is repeatedly struck and rotated by the impact, and water is sprayed from the sprinkling beak e' of the sprinkling beak tube.
Since it is attached to the lid receiving ring 20 which is rotatably attached around the support shaft i via the sliding washer 18 on the top, unnecessary energy loss required for rotation of the disc lid 8 can be eliminated and the cost can be reduced. It has the effect of being able to rotate easily depending on the water pressure.

When the water spraying is finished, that is, when the water supply is stopped, the rotary water sprayer will fall due to its own weight and close the disc lid 8.
The fixed outer ring body 4 has an inverted conical end face 9 on its outer periphery.
The screw fitting 26 is closely fitted to the inverted conical end face 3 of the inner circumference to prevent rainwater and dirt from entering from the outside, and is protruded from the center of the bottom of the head box 1 through which the piston pipe 7 slides.
Since the seal backing 12 and dust seal 13 are interposed in the cylinder, it is possible to completely prevent rainwater and dirt from entering the cylinder.
