Embodiment Construction

[0010] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A cone-angle self-adaptive atomizing fan-shaped nozzle based on a precise variable spray system. A liquid outlet 2 is opened at one end of the nozzle body. The liquid outlet 2 is a long and narrow rugby-ball-shaped gap opened outside the nozzle head 1 . There are three levels of cylindrical flow channels inside the fluid pipeline, and they are in a decreasing relationship. The diameter of the first level cylindrical flow channel 7 is greater than the diameter of the second level cylindrical flow channel 8, and the diameter of the second level cylindrical flow channel 8 is larger than that of the third level. The first-stage cylinder runner 9 and the axis of the third-stage cylinder runner are kept on a straight line. The stable atomization regulating flow channel is opened at the junction of the second-stage cylindrical flow channel and the inner nozzle ...

Abstract

The invention discloses a taper-angle self-adaption atomizing fan-type nozzle based on a precise variable spraying system, and belongs to the field of agricultural machinery. The nozzle comprises a nozzle head, a liquid outlet, a rigid adjusting ball body, a push rod and a stable atomizing adjusting flow channel; the stable atomizing adjusting flow channel communicates with an internal pipeline ofthe nozzle, when the internal pressure of the nozzle changes, a liquid in the stable atomizing adjusting flow channel can drive the push rod and the rigid adjusting ball body to reciprocate, and thenozzle head is made of an elastic material and can swing under the interaction of the rigid adjusting ball body and an inner nozzle body, so that self-adjustment of the grooving angle can be realized,and then the fog taper angle can be changed in real time. The nozzle is simple, reasonable and compact in structure, safe and reliable.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a cone angle self-adaptive atomizing fan nozzle based on a precision variable spray system. Background technique [0002] Accurate variable spraying technology has been valued by experts and scholars at home and abroad in recent years, and variable spray technology based on pipeline pressure regulation is an important solution for variable spraying. It collects key parameters such as vehicle speed, pressure, and flow rate to regulate pipeline pressure and realize Precise variable application. In the past, when the traditional fan nozzle was working, its physical structure and cutting angle were fixed. Therefore, frequent changes in the pipeline pressure lead to different atomization degrees of droplets. When the pressure increases, the fog cone angle increases. Uneven distribution. Therefore, there is an urgent need to produce a cone angle adaptive atomizing fan nozzle based on a...
