The invention belongs to the field of traffic facilities, and particularly relates to a traffic guidance sentry box capable of automatically reducing noise and reducing dust. The traffic guidance sentry box comprises a circular base, wherein the circular base is fixedly connected with the ground, and a hollow supporting rod is fixedly connected to the ground; a circular baffle is fixedly connectedto the hollow supporting rod, and a plurality of sound absorption cavities are formed in the circular baffle and are annularly distributed, and vibrating pieces are rotationally connected in the sound absorption cavities; piezoelectric ceramic pieces are embedded in the vibrating pieces, and a first cavity is formed in the circular base; and a plurality of air holes communicating with the first cavity are formed in the circular base, and the air holes correspond to the sound absorption cavities one to one. According to the traffic guidance sentry box, noise can be recycled, and an external power supply is not needed, so that the cost is saved; and dust flying around the sentry box can be eliminated while noise reduction is carried out, and a comfortable working environment is provided fortraffic police who direct traffic.
本发明属于交通设施领域，尤其是涉及一种可自动降噪及降尘的交通指挥岗亭，包括圆形底座，所述圆形底座固定连接有地面，且地面上固定连接有空心支撑杆，所述空心支撑杆上固定连接有圆形挡板，所述圆形挡板上开设有多个吸音腔，且吸音腔呈环形分布，所述吸音腔中转动连接有振动片，且振动片上嵌设有压电陶瓷片，所述圆形底座上开设有第一空腔，所述圆形底座上开设有多个与第一空腔相连通的气孔，且气孔与吸音腔一一对应。本发明可将噪音进行废物利用，无需外接电源，既节省了成本，且在进行降噪的同时，可以消除岗亭四周飞扬的灰尘，为指挥交通的交警提供舒适的工作环境。
