Intelligent tree maintenance device

The invention belongs to the field of municipal engineering, and particularly relates to an intelligent tree maintenance device which comprises a fixing ring fixedly connected with a supporting plate, a connecting piece rotationally connected with the fixing ring is arranged on the inner side of the fixing ring, a connecting plate is fixedly connected to the bottom end of the connecting piece, and a control column is connected to the bottom end of the connecting plate. And a plurality of detection mechanisms and a plurality of spraying mechanisms are arranged in the control column. The shape of the surface of a tree trunk can be recorded through the recording cylinder, then the opening size of the control valve can be controlled through the shape of the outer side wall of the recording cylinder, and in the process, the shape of the tree trunk can be recorded through deformation of the recording cylinder, so that the effect similar to disk data storage and reading is achieved; the spraying amount of white pulp
