And when the sprinkling irrigation closing cover 523 rotates and opens, the sprinkling irrigation closing cover 523 closes the first in-pipe notch 511 by the separation transmission component 524 and the drip irrigation closing cover 5133 with the double-notch closing mechanism 513, specifically, the sprinkling irrigation closing cover 523 rotates by pulling the interlocking pulling rope 5241, and the interlocking pulling rope 5241 is connected with the drip irrigation closing cover 5133 with the double-notch closing mechanism 513 under the action of the two steering rings 5242, and when the drip irrigation closing cover 5133 rotates along the third torsion spring connecting shaft 5132, the main drip irrigation pressure cover 5131 is separated until the main drip irrigation pressure cover rotates to be attached to the first in-pipe notch 511 and is closed, so that the drip irrigation nozzle 2 cannot discharge water in the process of spraying water by the sprinkling irrigation nozzle 3.
In addition, by dividing the flow rate grading mechanism 41 of the flow rate multistage adapting mechanism 4 into the water blocking disk 411 and the plurality of slide inner supporting strips 412, the water flow flowing into the sliding pipeline 12 from the four-way pipeline 11 mainly impacts on the water blocking disk 411 in a suspended state, so that the water blocking disk 411 can move towards the tail end opening under the action of the water flow, and the water flow is facilitated to pass through the gaps formed among the plurality of slide inner supporting strips 412.
When the pump body low-speed pump of control flow control unit sent water, the rivers of the inside circulation of irrigation water supply pipe can strike flow grader 41 and remove to the inboard annular 121 department of driping irrigation of sliding pipe 12 when, a clearance area for passing through rivers can increase, thereby promote the efficiency that rivers passed through, flow grader 41 can be restricted in the inboard annular 121 department of driping irrigation of sliding pipe 12 this moment, when the pump body high-speed pump of flow control unit sent water, the velocity of flow of rivers excessively increases the back, then can strike flow grader and remove to sliding pipe 12's annular 122 department of sprinkling irrigation, further increase the area in space this moment, make more hydroenergy pass through fast.
Through set up the shell part of irrigation unit for the cross four-way pipe 11 and the slip pipeline 12 of through-type, four-way pipe 11 makes shower nozzle interlocking device 5 open or interlocking in-process can not hinder rivers to flow through fast, reduces the influence to the multistage adaptation mechanism 4 of velocity of flow, slip pipeline 12 makes the multistage adaptation mechanism 4 of velocity of flow produce the in-process that removes at the cooperation rivers in the velocity of flow can restrict the velocity that rivers pass through in slip pipeline 12, and then produce the opening and the interlocking of sufficient pulling force control shower nozzle interlocking device 5.
The multistage adaptation mechanism of velocity of flow 4 is mainly opened and is switched drip irrigation shower nozzle 2 or spray irrigation shower nozzle 3 through the rivers velocity of flow of circulation in the cooperation irrigation water supply pipe, compare the mode of opening or closing the shower nozzle through the manual work, through the state that the mode that continuously sends the water pump into in the irrigation water supply pipe can be automatic and quick all little irrigation units of control, and inside the multistage adaptation mechanism of velocity of flow 4 of control switch wholly was in irrigation water supply pipe, also greatly reduced the probability that multistage adaptation mechanism of velocity of flow 4 damaged.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
