Embodiment 1

[0036] Such as Figure 1-Figure 2 As shown, this embodiment provides a load-feedback jet pulse dripper, preferably a sheet-type load-feedback jet pulse dripper, which mainly includes an upper plate 1, a main body 2 and a lower plate 3; the upper plate 1 is provided with a filter inlet 4, The lower plate 3 is provided with a water outlet hole 5; the main body 2 is provided with a water inlet chamber 2-1, a contraction section 2-2, a jet tube 2-3, a jet space 2-4, a splitter 2-5, and a labyrinth channel 2 -6 and the water outlet chamber 2-7; the water inlet chamber 2-1 is located at the front end of the main body 2, and communicates with the filter inlet 4 to realize water intake; the end of the water inlet chamber 2-1 is connected with a conical contraction section with a large front and a small rear 2-2, the end of the contraction section 2-2 is connected to a rectangular jet tube 2-3, and the end of the jet tube 2-3 is connected to a trapezoidal jet space 2-4 with a small fro...

Embodiment 2

[0046] This embodiment is an improvement made on the basis of Embodiment 1, and its improvements are as follows: Figure 3-Figure 4 As shown, the load feedback jet pulse dripper is a cylindrical load feedback jet pulse dripper, and the splitter 2-5 of the cylindrical load feedback jet pulse dripper divides the jet space 2-4 into two channels, and the two labyrinth flow channels 2 The front ends of -6 communicate with two adjacent passages respectively, wherein the labyrinth passage may include a plurality of vertical passages connected in sequence from end to end.

[0047] When the cylindrical load feedback jet pulse dripper is set in the drip irrigation pipeline, the outer surface of the cylindrical load feedback jet pulse dripper is embedded on the inner wall of the drip irrigation pipeline, and corresponds to the position of the center of the water outlet cavity 2-7 on the drip irrigation pipeline wall surface Opening, the area of ​​the opening is smaller than the minimum f...

Abstract

The invention discloses a load feedback jet pulse water dropper, and relates to the technical field of water-saving agriculture, the load feedback jet pulse water dropper comprises a main body, the main body is connected with a filtering inlet, two labyrinth flow channels are arranged in the main body, and the tail end of each labyrinth flow channel is provided with a water outlet cavity; the two water outlet cavities are jointly connected to the same water outlet hole, the sectional area of the water outlet hole is smaller than the minimum overflowing sectional area of the labyrinth flow channel, a plugging device is further arranged between the two water outlet cavities, and the plugging device can reciprocate between the two water outlet cavities to plug one of the water outlet cavities. The invention further discloses a drip irrigation system adopting the load feedback jet pulse water dropper. According to the invention, the pulse amplitude can be increased, the pulse drip irrigation oscillation effect can be improved, and the anti-clogging capability can be improved.

Description

technical field [0001] The invention relates to the technical field of water-saving agriculture, in particular to a load feedback jet pulse dripper and a drip irrigation system. Background technique [0002] Drip irrigation is one of the most water-saving irrigation technologies in the world, and it is also the most widely used water-saving irrigation technology in the world. Clogging is a key issue affecting the development of drip irrigation technology, especially the integrated water and fertilizer technology, subsurface drip irrigation technology, and brackish water drip irrigation technology that are now widely used, all of which have put forward stricter requirements for the anti-clogging of drip irrigation systems. [0003] The pulse drip irrigation technology has good anti-clogging performance. The existing pulse drip irrigation technology mainly uses frequency conversion control technology or elastic materials such as rubber and springs to generate pulses. However,...
