The invention discloses rapid
lime solution spraying equipment for a
tree trunk which comprises a vehicle-mounted platform, a
lime solution container, a
pipe section, a rack, a movement mechanism and a spraying mechanism. The
lime solution container is arranged on the vehicle-mounted platform and connected with the spraying mechanism through the
pipe section, the spraying mechanism is arranged on the movement mechanism, and the movement mechanism is installed on the rack. Spraying and rack parts executing operation are connected with a
control unit, a power source and the vehicle-mounted platform of the lime solution container through the
pipe section, and distance limitation of a
tree trunk and a
road surface can be avoided; in the operation process, two clamping rings abut against the
tree trunk, multiple fan nozzles on a bearing ring form an annular spraying face for the tree
trunk in the circumferential direction, a start and stop button is pressed down, the spraying mechanism is driven by the movement mechanism to automatically complete even spraying of the tree
trunk from top to bottom, and therefore the function using requirement of rapid and efficient lime solution spraying is effectively achieved; and meanwhile, the structure is simple, cost is low, operation is convenient, and the manpower is greatly saved.
