Machine body of full-automatic cleaning machine

The invention relates to a machine body of a full-automatic cleaning machine. The machine body comprises a bottom plate, four vertical columns, eight connecting columns and two lifting devices. The four vertical columns are symmetrically and fixedly connected to the two sides of the bottom plate. The eight connecting columns are symmetrically and fixedly connected between the four connecting columns, and the lower end faces of the four connecting columns on the lower side are fixedly connected with the bottom plate. The two lifting devices are located on the two sides of the bottom plate, and each lifting device is installed between every two adjacent connecting columns and comprises a drive motor, a lead screw, a lifting sliding block and a lead screw nut. The drive motors are installed on the connecting columns through motor seats, the lower ends of the lead screws are connected with output shafts of the drive motors through couplers, the upper ends of the lead screws are connected with the connecting columns through bearings, the lifting sliding blocks are connected with the lead screws through the lead screw nuts, the vertically-lifting adjusting function of the lifting sliding blocks is achieved through transmission of the lead screws and the lead screw nuts, the structure is simple, and adjusting performance is good. The machine body can achieve the automatic cleaning function for a compartment in an assisting mode and has the advantages of being simple in structure, good in adjustable performance and the like.
