Abstract

The utility model discloses an electric girdling device for winter jujube tree branches, which comprises a direct current brushless motor, a rotating output shaft of the direct current brushless motor is connected with one end of a planetary reducer, and the other end of the planetary reducer is connected with a driving bevel gear. The driving bevel gear is in transmission connection with a girdling transmission gear arranged on the periphery of the turnover girdling tool bit through a gear set. The phloem of a winter jujube tree branch is surrounded and stripped through the girdling tool bit driven by the motor, the clamping mechanism can change along with the diameter of the winter jujube tree branch, operation is easy and convenient, the labor intensity of orchard workers is greatly relieved, and working efficiency is improved.
