背景技术Background technique
抹平机广泛用于各种厂房、仓库、广场、混泥土地坪等施工场所，混凝泥浇注后通过抹平机抹平，抹平机比人工抹平效率高很多，因此通常大面积混泥土抹平都采用抹平机作业。抹平机作业时需要调节抹刀片的角度，抹平机停止作业时，抹刀片处于水平状态，抹平机工作时，调节抹刀片，使得抹刀片与地面之间构成30°夹角，目前常见的抹平机上的抹刀片都是采用涡轮、蜗杆手动调节，调节速度慢，效率低，严重影响抹平机工作效率。The troweling machine is widely used in various workshops, warehouses, squares, concrete floors and other construction sites. After the concrete is poured, it is smoothed by the troweling machine. The troweling machine is much more efficient than manual troweling. Soil smoothing is done with a trowel. When the trowel is working, it is necessary to adjust the angle of the trowel blade. When the trowel stops working, the trowel is in a horizontal state. When the trowel is working, adjust the trowel so that the angle between the trowel and the ground is 30°. The trowel blades on the trowel are manually adjusted by turbine and worm, the adjustment speed is slow and the efficiency is low, which seriously affects the work efficiency of the trowel.
