Problems solved by technology

The structure is more complex and the energy conversion rate is not high
The rocker spring of the sprinkler works frequently, and the working life is far lower than that of other parts of the sprinkler. This is an insurmountable bottleneck in the promotion and application of the rocker sprinkler.
The full-jet nozzle relies on the attached wall of the water flow to realize the stepping and reversing of the nozzle. It has the characteristics of simple structure and good spraying performance, but it has the disadvantage that it is difficult to reduce the production cost due to the high processing precision requirements, which makes the industrialization development limited. limit
[0003] After searching, there is no declared patent for the nozzle structure of this special-shaped nozzle

Embodiment Construction

[0014] The special-shaped nozzle full-jet nozzle is composed of four parts: a rotary sealing mechanism (1), a flow channel (2), a reversing mechanism (3), and a special-shaped jet element body (4). The special-shaped jet element body is not only the nozzle outlet part of the spraying operation, but also the control part for automatic control to complete direct spraying, stepping and reverse. The special-shaped jet element body is composed of signal nozzle I (5), signal nozzle II (6), reverse nozzle (7), nozzle (8) and action area (9). Using the interception and flow of signal water in signal nozzle I (5) and signal nozzle II (6), the opening and closing of the reverse nozzle (7) realizes the wall attachment of the water flow, thereby completing the direct injection, stepping and reverse of the nozzle run. The nozzle of the special-shaped jet element body is non-circular, and the signal mouth 1 water intake position of the nozzle has a groove, and the groove can be arc-shaped,...

Abstract

The present invention especially indicates a complete fluidic sprinkler of the special-shaped nozzle. The invention is composed of four components of rotary a sealing device, a flow passage, a reversing mechanism and a special-shaped fluidic element. The nozzle is non-circular and the groove which lies on the I side of the signal nozzle on the nozzle is arc-shaped, rectangular or triangular. During operation the water current passes through the rotary sealing device and the flow passage and is ejected from the special-shaped fluidic element. When the water current passes the nozzle of the special-shaped fluidic element the water current at the groove enters the signal nozzle I and causes that the clearance C of the right cavity of the element is smaller and smaller and is blocked finally, the pressure difference between the left and right cavity push the power stream to the right, a wall is generated and the whole element rotates to the right. At the condition of wall the signal nozzle I comes away from the power stream and only the air can be obtained as the bending of the power stream. The air is sent from the reverse connection mouth to the signal nozzle II and adds air to the right cavity, finally the pressure difference between the left cavity and the right cavity disappears, the perpendicular incidence condition gets back and the rotation of the nozzle to the right side stops. The whole showerhead has the advantages of simple structure, low price, stable working and good atomizing performance.

Description

technical field [0001] The invention belongs to key equipment for water-saving irrigation, in particular to a special-shaped nozzle full-jet nozzle. Background technique [0002] At present, my country's agricultural water consumption accounts for about 80% of the national water consumption. The efficiency of agricultural water use is not high, and water resources are seriously wasted, which further aggravates the lack of agricultural water resources. Among various irrigation technologies, sprinkler irrigation technology is one of the most important water-saving irrigation technologies in the world today, with wide application and wide adaptability. In sprinkler irrigation equipment, the rotary sprinkler head widely used at present is the rocker type sprinkler head, which is composed of a flow channel, a rotary sealing mechanism, a driving mechanism, and a reversing mechanism. The drive mechanism is made up of rocking arm, rocking arm shaft, rocking arm spring, spring seat ...
