Background technique

At present, various sprinklers used in irrigation in the field of agricultural micro-irrigation technology are equipped with a set of labyrinth flow channels at the front of each drip outlet. The labyrinth flow channels are roughly divided into two types. One is formed separately and then embedded in the emitter. Or plugged outside the emitter; when watering, the water flow enters the flow channel and enters the labyrinth directly, and the labyrinth is easily blocked after the sediment is continuously deposited; after the emitter stops watering, the negative pressure generated by the capillary may dislodge tiny particles in the soil Inhale the micropores of the emitter and cause blockage. The water-oriented growth of the plant root system may cause the root to invade the drip hole and cause blockage, so that the original emitter cannot evenly transmit water to the roots of the plant. Therefore, the water cannot be fully utilized. cause waste of water resources.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in Figure 1, the high anti-clogging emitter includes a water delivery chamber 1 and an irrigation chamber 2, the irrigation chamber 2 is provided with an irrigation flow channel 3, and the irrigation flow channel 3 has a water inlet 4 and a water outlet 6 , the number of water inlet pipes at the water inlet 4 is 1 to 5; the water delivery chamber 1 communicates with the irrigation channel through the water inlet 4, and the water outlet 6 communicates with the outside of the high anti-clogging emitter.

The irrigation flow channel includes an inclined water inlet section 7 connected in sequence, a centrifugal section 8 with a spiral centrifugal column, a sedimentation section 9 composed of a flat flow channel, and an energy dissipation section 10 composed of a continuous "S"-shaped or wave-shaped flow channel, A water outlet section 11 made of a flat flow channel; the flow channel of the deposition section 9 is a conical flow channel with a large diameter facing the centrifugal section, and the conical shape of the deposition section 9 is provided with a plurality of collection chambers 12, and each collection chamber is Semi-closed, the opening communicates with the irrigation flow channel, and the collection chamber 12 is connected to the bottom of the irrigation flow channel at an acute angle;

The opening 14 of the collection chamber communicates with the water irrigation flow channel, and the collection chamber 12 is connected with the bottom direction of the water irrigation flow channel 3 at an acute angle.

As shown in Figure 2 and Figure 3, a closed air pressure chamber 15 is provided around the outer wall of the collection chamber 12, the air pressure chamber 15 is negative pressure, and the air pressure chamber seals the outside of the collection chamber, and under the effect of negative pressure, the collection chamber 12 is always Keep it open to facilitate the deposition of sediment.

The silt coming out of the centrifugal section 8 has a tendency to move to the wall of the sedimentation section 9. Under the action of gravity, the silt is left in the collection chamber 12 to prevent blocking the flow channel; the geometric size of the collection chamber 12 is larger than that of the sedimentation section. Because the water flowing from the centrifugal section enters along the inner wall of the irrigation flow channel, it directly enters the collection chamber. The sediment has gravity and is easy to deposit in the collection chamber 12. The shape of the collection chamber 12 is like a bag, and the sediment is easy to enter. It is not easy to come out, so that the sediment is deposited in the collection chamber 12, and the pressure is quickly reduced. The opening of the collection chamber is funnel-shaped, that is, the size of the side facing the flow channel of the deposition section is larger than the size of the side facing the inside of the collection chamber, which is conducive to the entry of sediment into the collection chamber and has a good anti-clogging effect.
