Spray controller for water sprinkler

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

technical field [0001] The present invention relates to a "sprinkler water splash change control device", which utilizes two water outlet holes facing each other in the water channel to cooperate with the block and water inlet space of the water splash control part, and is directly driven by the gear transmission group through the interlocking gear. A structure in which the blocking blocks are rotated to gradually change the water flow is formed in conjunction with each other, so that the water splash control part will not be hindered by the water flow when it is actuated, and the gear transmission wheel set will be more favorable when it is driven. It saves labor, and can indeed drive the water splash control part, making the structural design and control easier and more accurate. Background technique [0002] As shown in Figure 1, it is a known three-dimensional cross-sectional internal structure schematic diagram, the water of the sprinkler 10 flows through the water inle...

Problems solved by technology

[0003] The above-mentioned known structure has the following defects: one, it sprays to the water wheel 12 and needs enough water pressure to drive the round wheel 15 and the plug body 16 to rotate in sequence when it rotates. When the water wheel 12 is sprayed to the water wheel 12, it cannot rotate and stagnate under the mutual restraint of the round wheel 15 and the plug body 16; In the sliding seat 17, even at high water pressure, the water flow inside the sliding seat 17 will form a resistance, causing the movement of the plug body 16 to be blocked, and it will also cause the water wheel 12 to spin due to being restrained by the plug body 16. Difficult to move

[0004] In addition, the sprinkler seat of U.S. Patent No. 4860954 uses the rotation of the impeller to drive the screw for reciprocating motion, and an eccentric cam is arranged on one side of the screw to communicate with the channel, so the required components are numerous and the structure is complicated. , relatively causing difficulty and time-consuming assembly
