ーザ付きバツクホウの操作構造。 A swivel base 2 equipped with a backhoe device 3, a boarding type driving unit 4, and a driving unit 5 is attached to a traveling machine base 1 equipped with an angle dozer 7, and one operation valve V10 for the angle dozer 7 is installed as shown in FIG. A hydraulic cylinder C 5 for raising and lowering the angle dozer 7 and a hydraulic cylinder C 6 for adjusting the angle changing the left and right direction of the angle dozer 7 are connected to the operation valve V 10 , and are installed opposite to the swivel base 2 . This is an operating structure for a backhoe with an angle dozer in which an operation target switching valve V 13 for selective connection is attached to the traveling machine base 1, and a swing lock pin 12 for preventing rotation of the swivel base 2 is provided. The rotating lock pin 12 is disposed in the riding type operating section 4 in a state where it can be freely changed between a first locking position L1 and a second locking position L2 , and the swinging lock pin 12 is attached to the first locking position L1 . The dozer lifting/lowering hydraulic cylinder C5 operates the operation target switching valve V13 to a first connected state in which it is connected to the operation valve V10 , and the swinging cylinder is installed at the second locking position L2 . The lock pin 12 is placed in the first locking position L1 and in the second position so as to operate the operation target switching valve V13 to a second connected state in which the angle adjustment hydraulic cylinder C6 is connected to the operation valve V10 . The operation structure of a backhoe with an angle dozer in which a locking position L2 is arranged.
