Abstract

The invention discloses a spray change controller of water sprinkler, wherein the water sprinkler swings an injector via a spray control group, the spray control group comprises a gear transmitter with blade wheels linked with a spray change controller. The spray change controller is formed by a water channel with two water inlets and a spray control element with linkage gear and two blocks at two sides. The linkage gear of the control element is directly meshed with one gear of the gear transmitter while two water inlets are engaged with the blocks, therefore, the linkage gear and the blocks can screw along with the gear transmit to change the inlet water at two inlets to uniformly spray water from far to near on the grass.

Description

The spray change control apparatus of water sprinkler

Technical field

The present invention relates to a kind of " the spray change control apparatus of water sprinkler ", its utilize the screening piece of two relative apopores of water channel and spray control piece and water inlet space to cooperatively interact and by linked gear directly by the gear drive group gradually preface drive form mutual interlock order hide piece with the mode of turn gradually preface change the structure of water yield, so that the spray control piece when start except that can not being subjected to the obstructing of current, more making gear pass wheels more takes advantage of a situation laborsaving when driving, and then can drive the spray control piece really, make structural design and control all comparatively simple and easy and accurately.

Background technology

Being illustrated in figure 1 as known solid cuts open and shows the internal structure schematic diagram, the current of its watering device 10 spray to water wheels 12 through water inlet 11 makes it rotate and during interlock scroll bar 13, its turbine 14 is driven by scroll bar 13,15 coaxial on circle wheel is followed turbine 14 and is rotated, it fastens in the nose bar 161 of spiral-guide groove 151 and promoted by the rotation of spiral-guide groove 151 and cooperate the oval slotted hole 171 of sliding seat 17 spacing and it is move forward and backward, the cock body 16 of its one thereby also the hydrospace thereupon moving forward and backward to be forced to delivery port 18 and to change is changed the water yield of delivery port 18.

Aforesaid known configurations, it has following defective: one, it sprays to water wheels 12 need have enough hydraulic pressure can drive circle wheel 15 and cock body 16 turns in regular turn when turn, in case when low hydraulic pressure, spray to water wheels 12 circle wheel 15 and pining down mutually of cock body 16 are next can't turn and stagnate; When two, its cock body 16 moves forward and backward in sliding seat 17, current then can be infiltrated in the sliding seat 17 by oval slotted hole 171, even in high hydraulic pressure, sliding seat 17 inner existing current also can form one resistance, outside causing cock body 16 to move to be obstructed, more can make spray to water wheels 12 because of be subjected to cock body 16 to pin down turn painstaking.

In addition, the watering seat that No. the 4860954th, the United States Patent (USP) notification number is to utilize the turn of impeller to drive screw rod to do reciprocal motion, establish an eccentric cam in a side of screw rod and communicate with passage, thus must the comparatively various and complex structure of element, cause relatively in the assembling the difficulty and consuming time.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of spray change control apparatus of water sprinkler, to improve the above-mentioned defective of known technology.

Technical solution of the present invention is: a kind of spray change control apparatus of water sprinkler, its water sprinkler is to drive water body by a spray control group to do swing on the angle, a gear drive group and the mutual interlock of a spray change control apparatus with impeller established in the inside of described spray control group, this spray change control apparatus is made up of a water channel and the spray control piece with a plurality of water inlets, described spray control piece one side has linked gear, opposite side has a plurality of screening pieces, the linked gear of spray control piece directly and a wherein gears engaged of gear drive group, and relative group of establishing of water inlet and screening piece closed, the linked gear of described spray control piece and hide piece and change the water yield of going into of water inlet with the gradually preface turn of gear drive group, so the spray that makes ejection from far near again by near to far away on average being sprayed on the lawn.

Characteristics of the present invention and advantage are: the spray change control apparatus of water sprinkler of the present invention, it utilizes the linked gear of spray control piece directly to be meshed with a wherein gear of gear drive group to form mutual interlock and makes and hide piece with the mode of the turn structure of preface change water yield gradually, make the spray control piece in start except that can not being subjected to the obstructing of current, more make gear pass wheels and on driving, more take advantage of a situation easily and can drive the spray control piece really; In addition, the spray change control apparatus of water sprinkler of the present invention, its utilize the screening piece of the water inlet of water channel and spray control piece and water inlet space to cooperatively interact and by linked gear directly by the gear drive group structure that drives of preface gradually, make this be installed on structural design and control all comparatively simple and easy and accurately.
