The water yield of head ensures the normal water yield of drip head 2, when stopping fertilising, since external force removes, and compressed spring 1034
With a reversed active force, 10333 counter motion of sliding bar is pushed, thus by the air extrusion in annular chamber 1015 to close
It seals in chamber 1014, pressure block 1013 is released and realizes reset, scraper plate 10332 reversely strikes off during reset, will fill in head
Knot layer on parietal layer 102 is rejected more clean.
Problems solved by the invention is that traditional fertilization mode is applied fertilizer by way of trickle irrigation, this fertilization mode energy
Pipe irrigation is carried out to the root of crops, but since liquid fertilizer is to mix the system of exchanging uniform in proportion with water by powdered fertilizer
At, therefore after stopping irrigating, the inside of irrigation head has partially liq Residual Fertilizer, and due to the evaporation of moisture, residual
Medicinal powder can be adhered on drip head inner wall, the water yield of drip head can be reduced over time, the present invention passes through above-mentioned component
It is combined with each other, pushes two ring shaped movable plates 1011 open by the impact force of liquid fertilizer, so that two ring shaped movable plates 1011
Movement is runed counter to, so that pressure block 1013 be promoted, so that the air obtained in seal chamber 1014 flows in annular chamber 1015, reaches and pushes away
Dynamic sliding bar 10333 moves, and sliding bar 10333 drives scraper plate 10332 to be close to and fills the movement of head inner wall layer 102, will fill head inner wall
Adhesive layer after liquid fertilizer remnants are air-dried on layer 102 strikes off, and the water yield of drip head can be reduced by avoiding adhesive layer accumulation, protects
Hinder the normal water yield of drip head 2.
