[0036] Such as Figure 1-Figure 2 As shown, this embodiment provides a jet vibrator dripper, preferably a chip type jet vibrator dripper, mainly including a panel 1, a main body 2 and a bottom plate 3, etc., the panel 1 is provided with a filter window 4, and the bottom plate 3 is provided with a water outlet hole 6; the main body 2 includes a water inlet section 2-1, a contraction section 2-2, a jet section 2-3, a feedback channel 2-4, a jet space 2-5, a vibrator 2-6, a splitter 2-7, Runner 2-8, water outlet tank 2-9, limit plate 2-10; the water inlet section 2-1 is located at the front end of the main body 2, and the water inlet section 2-1 is followed by a shrinking section with a large front and a small rear 2-2, the contraction section 2-2 is followed by a rectangular jet section 2-3, behind the jet section 2-3 is a trapezoidal jet space 2-5 with a small front and a large rear; the middle of the end of the jet space 2-5 is set A shunt splitter 2-7, in front of the shunt ...

Embodiment 2

[0046] This embodiment is an improvement made on the basis of Embodiment 1, and its improvements are as follows: image 3 As shown, the water outlet grooves 2-9 at the ends of the flow channels 2-8 on the left and right sides are connected to the same water outlet hole 6, and the water outlet hole is located in the middle of the two water outlet grooves 2-9.

Embodiment 3

[0048] This embodiment is an improvement made on the basis of Embodiment 1, and its improvements are as follows: Figure 4-Figure 5 As shown, the jet vibrator dripper is a cylindrical jet vibrator dripper, including a cylindrical shell, the main body is arranged in the shell, and the filter inlet of the main body is exposed; wherein, the flow channel 2-8 can include a plurality of vertical tubes connected in sequence from end to end. Channels, the feedback channels 2-4 of the cylindrical jet vibrator dripper are arranged around the circumference.

[0049] When a cylindrical jet vibrator dripper is set in the drip irrigation pipeline, the outer surface of the cylindrical jet vibrator dripper is embedded on the inner wall of the drip irrigation pipeline, and a hole is opened on the wall surface of the drip irrigation pipeline corresponding to the center of the water outlet tank 2-9. The hole area is smaller than the area of ​​the water outlet tank 2-9; at this time, the opening ...

Abstract

The invention discloses a jet-flow vibrator water dropper, and relates to the technical field of agricultural water-saving irrigation, the jet-flow vibrator water dropper comprises a main body, the main body is connected with a filtering inlet, the main body is also internally provided with a water inlet section, a contraction section, a jet-flow section and a jet-flow space which are communicated in sequence, and the filtering inlet covers the upper part of the water inlet section; two flow channels are arranged in the main body, the front ends of the two flow channels are connected with the tail end of the jet flow space, the two flow channels are further connected with a water outlet groove, and the water outlet groove can be connected with the water outlet hole; a vibrator is further arranged between the front ends of the two flow channels, and the vibrator can block one of the flow channels under the impact of water flow; the two side wall faces of the front end of the jet flow space are each provided with a channel hole, and the two channel holes are connected through a feedback channel. The pulse amplitude can be increased, the average flow of the water dropper is reduced, and irrigation is more uniform.

Description

technical field [0001] The invention relates to the technical field of agricultural water-saving irrigation, in particular to a jet vibrator dripper and a drip irrigation system. Background technique [0002] Drip irrigation is one of the most water-saving irrigation methods recognized in the world, but clogging is a restrictive factor affecting the quality and service life of drip irrigation. Studies have shown that pulse drip irrigation has the characteristics of strong anti-clogging performance and high uniformity of irrigation. [0003] The pulse generator is the core device that turns the pressure water flow in the drip irrigation system into a pulse water flow. The existing pulse generator is generally composed of electronic frequency conversion, rubber, plastic diaphragm or spring and other elastic materials. The purpose of pulsating water flow is realized by using frequency conversion device or the expansion and reset of elastic materials such as rubber, plastic and...
