The invention relates to a municipal trencher. The problems that a trench excavated by a trencher is poor in flatness, much in surface dust and high in dust raising and noise are effectively solved. According to the technical scheme, the municipal trencher comprises a construction vehicle, wherein a cutting unit is installed at the front end of the construction vehicle; the cutting unit comprisesa plurality of cutting blades which are arranged at intervals in the left-right direction; a vertical auger is installed at the rear end of a vehicle plate; the lower end of the auger penetrates through the vehicle plate; a rectangular box body with an opening in the lower end is installed at the lower end of the auger; the lower end of the auger extends into the box body; a shovel plate is hingedto the bottom of the box body; a cable-stayed hydraulic cylinder is hinged to the lower surface of the vehicle plate; the cable-stayed hydraulic cylinder is connected with the rear end of the shovelplate; and the cable-stayed hydraulic cylinder lifts the rear end of the shovel plate upwards so that the shovel plate can rotate around a hinge shaft and the front end of the shovel plate can cut into the ground. According to the municipal trencher, the flatness of the side wall and the bottom of the excavated trench is good, the surface dust in the trench is extremely little, leveling and soil cleaning are not needed, the construction efficiency is greatly improved, dust raising is not prone to being caused, the noise is low, and the municipal trencher better conforms to the green construction concept.
本发明涉及一种市政挖沟机，有效的解决了挖沟机开挖的沟渠平整度不好，浮土多，扬尘和噪音大的问题；解决的技术方案包括施工车，施工车前端安装有切割单元，切割单元包括多个左右间隔布置的切割刀片，车板的后端安装有一个竖向的绞龙，绞龙的下端穿过车板，绞龙下端安装有一个下端开口的矩形的箱体，绞龙下端伸入箱体内，箱体底部铰接有一个铲板，车板下表面铰接有一个斜拉液压缸，斜拉液压缸与铲板的后端相连，斜拉液压缸向上提拉铲板的后端可使铲板绕铰接轴转动从而使铲板前端切入地面；本发明开挖的沟渠侧壁和底部平整度良好，沟内浮土极少，无需再进行整平和清土，大大提高了施工效率，且不易造成扬尘，噪音小，更符合绿色施工理念。
