The invention relates to an automatic spraying angle control mechanical system for inhibiting sand blowing of a helicopter. The device is composed of a spring, a stop lever, an ejector rod, a sleeve, a pressing rod, a cam, a balance block and a fixing pipe. The spraying angle of the helicopter dust removal spray can be accurately controlled. The on-off state of the device is controlled by matching assemblies composed of ejector rods, sleeves and pressing rods with stop levers and springs at the tail ends of the wings, when the wings rotate, rollers at the heads of the pressing rods move along the profiles of cams to the profile protrusions, the pressing rods push the ejector rods towards the interiors of the wings, at the moment, the assemblies are matched with one another to play a role, and the nozzles are opened. And the roller continues to move to the next contour bulge along the cam contour, the assembly plays a role again, and the spray head is closed. According to the invention, the effect of controlling the spraying angle can be achieved while the basic functions of the dust removal device are ensured by using a more stable mechanical structure.
本发明是一种用于直升机扬沙抑制的自动喷雾角度控制机械系统。该装置由弹簧、挡杆、顶杆、套筒、压杆、凸轮、平衡块、固定管组成。本发明可以精准控制直升机除尘喷雾的喷洒角度。装置通过顶杆、套筒、压杆组成的组合件配合挡杆以及机翼末端的弹簧来控制装置的开关状态,机翼旋转时压杆头部的滚轮沿凸轮轮廓运动,运动至轮廓凸起处,压杆向机翼内部推动顶杆,此时组合件相互配合发挥作用,喷头打开。滚轮继续沿凸轮轮廓运动至下一轮廓凸起处,组合件再次发挥作用,喷头关闭。本发明能使用更稳定的机械结构在保证除尘装置的基本功能的同时达到控制喷洒角度的效果。
