<P>PROBLEM TO BE SOLVED: To suitably control an attitude of a pruning machine body. <P>SOLUTION: An automatic pruning apparatus includes a pruning machine body 2 and a plurality of a vertical movement mechanisms 3 that vertically move the pruning machine body 2. Each of the vertical movement mechanism 3 includes: an upper wheel 31a and lower wheel 31b that are driven to rotate by a drive motor 32; a connection support 33 that connects and supports the upper wheel 31a and the lower wheel 31b; an advance/retreat part 34 that advances and retreats the connection support 33 to a trunk while that the mechanism journals the connection support 33 to freely rotate; and an inclination angle detection part 35 that is disposed between the connection part 33 and the advance/retreat part 34 and detects an inclination angle θ of the connection support 33. Thereby, the automatic pruning apparatus controls the drive motor 32 of each vertical movement mechanism 3, based on the inclination angle θ of the connection support 33 that is determined by the inclination angle detection part 35 of each vertical movement mechanism 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
