Abstract
The utility model discloses a water saving spray head which is composed of a rotatory spray head, a water filling pipe, etc., wherein a bearing being connected with the rotatory spray head is arranged between the rotatory spray head and the water filling pipe and is also connected with a connecting rod of which the lower end is also connected with a bearing which is connected with a driving gear which vertically is engaged with a driven gear which drives a throttling piece and causing the throttling piece to be rotated with uniform speed using the diameter of the cross section as an axis in the water filling pipe. The water saving spray head solves that the water saving can not spray outside polygon green land and flower beds at the time of spraying polygon green land and flower beds, has no influence on the traffic of pedestrians and can be convenient fabricated.
Description
Technical field
The utility model relates to a kind of sprinkling irrigation instrument, the shower nozzle of definite a kind of usefulness of spraying of saying so.
Background technology
Along with expanding economy, city, suburban environment are beautified and more and more are subjected to people's attention, greenery patches and flower bed in the park are different, adopting all generally that sprinkling irrigation is watered, fertilising or pesticide, and the shower nozzle of sprinkling irrigation usefulness is machine-made circular shower nozzle, water, liquid fertilizer or the liquid pesticide of such shower nozzle ejection are circular arc.When spraying polygonal greenery patches and flower bed, can be sprayed on the flower bed outside, also can be sprayed at sometimes on pedestrian's the body, both caused waste, influence passing through of pedestrian again, solve this difficult problem so want to design a shower nozzle that can spray the polygon lawn.
Summary of the invention
The purpose of this utility model provides a kind of can change the range and the injection flow rate of water immediately according to the shape on sprinkling irrigation lawn, can spray the shower nozzle on polygon lawn.
For achieving the above object, the utility model comprises a rotary nozzle, a connecting rod, a driving gear, a driven gear, two bearings and six parts of a throttling sheet.Wherein, connecting rod, driving gear and bearing are formed a power train; The throttling sheet works to change hydraulic pressure, current.Can rotate under the reaction of the current of rotation sprayer, and drive power train, final envoy's flow serves as that axle is done at the uniform velocity rotation with its cross-sectional diameter in water injection pipe.The choked flow that the throttling sheet is caused with respect to the inclination angle difference of water injection pipe cross section in water injection pipe, damping value are also different.When throttling sheet inclination angle is that 180 choked flows when spending, damping value are for maximum; When throttling sheet inclination angle is 90 when spending, choked flow, damping value are minimum.Because the throttling sheet is done at the uniform velocity rotation, thus its choked flow, damping maximum and the alternate appearance of minimum of a value meeting, even transition; Because the range of current depends on the hydraulic pressure value in the water injection pipe, just can change range, minimum of a value and peaked ratio again so change the area of throttling sheet.
The throttling sheet is driven by driven gear, whenever revolves the number of turns of throttling sheet rotation that turns around so the gear ratio of change driving gear and driven gear just can change rotary nozzle, thereby reaches the purpose of periodically-varied range.
Along with development, the popularization of sprinkler irrigation technique, the utility model will have vast market to be worth.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model comprises rotation sprayer 1, connecting rod 2, driving gear 3, driven gear 4, bearing 5, throttling sheet 6, rotation sprayer 1 can rotate under the reaction of current, and drive bearing 5 and driving gear 3, driven gear 4 is vertical meshing with driving gear 3, driven gear 4 drives throttling sheets 6, and envoy's flow 6 serves as that axle is done at the uniform velocity rotation with its cross-sectional diameter in water injection pipe.The choked flow that throttling sheet 6 is caused with respect to the inclination angle difference of water injection pipe cross section in water injection pipe, damping value are also different.Because doing, throttling sheet 6 at the uniform velocity becomes rotation, so its choked flow, damping maximum and at the uniform velocity transition of the minimum of a value alternate appearance of meeting; Because the range of current depends on the hydraulic pressure value in the water injection pipe, just can change range, minimum of a value and peaked ratio again so change the area of throttling sheet 6.Because driving wheel 3 is identical with rotary nozzle 1 swing circle, throttling sheet 6 is driven by driven gear 4, whenever revolve the number of turns of throttling sheet 6 rotations that turns around so the gear ratio of change driving gear 3 and driven gear 4 just can change rotary nozzle 1, thereby reach the purpose of periodically-varied range.
The utility model is made simple, helps the conserve water resource, and market prospects are good.
Claims (1)
1, a kind of water-saving spray head, form by rotary nozzle, water injection pipe etc., it is characterized in that between rotary nozzle and water injection pipe, being provided with the bearing that is connected with rotary nozzle, it is connected with connecting rod again, the connecting rod lower end also connects a bearing and is connected with driving gear, driven gear is vertical with driving gear meshing, and driven gear drives the throttling sheet, and envoy's flow serves as that axle is done at the uniform velocity rotation with its cross-sectional diameter in water injection pipe.
