Speed is identical.
Further, the direct output shaft of the hydraulic motor is connect with chain active rotation wheel, chain active rotation wheel belt
Dynamic cutting chain is rotated.
Further, the chain cutter runing rest and chain supporting support are welded, chain active rotation wheel and
The driven rotating wheel of chain is fixed in chain supporting support to be rotated around respective rotary shaft.
Further, described device, which need to only change hydraulic motor disengaging, the direction of mouth, so that it may straight to change hydraulic motor
Connect the direction of rotation of output shaft and chain cutter runing rest.
Compared with prior art, the present invention has the following advantages：
The invention discloses a kind of cutter that chops at a tree based on hydraulic motor, including including hydraulic motor, planetary gear structure and
Cutting tool, planetary gear structure include planet axis driving gear, planet driven gear, planetary output shaft gear, planetary gear rotation
Holder, planetary gear connecting shaft, planet driving gear, planetary gear output shaft, planet axis driving gear and hydraulic motor output shaft
Connection, under the drive of hydraulic motor, makes the planet driving gear engaged be rotated, planet driving gear and planet from
Moving gear can rotate under the connection of planetary gear connecting shaft with angular speed, and planet driven gear exports axis connection with planetary gear
The rotation of chain cutter runing rest can be driven in the planetary output shaft gear rotation engaged, planetary gear output shaft, to
Complete cutting movement.Hydraulic motor driving shaft and the direct output shaft of hydraulic motor are directly coaxially connected, and hydraulic motor directly exports
Axis connect that cutting chain is driven cut trees with chain active rotation wheel.One kind provided by the invention is based on
The cutter that chops at a tree of hydraulic motor can chop at a tree mounted on device drives this to chop at a tree on cutter on device by hydraulic pump output hydraulic pressure oil, liquid
The power output of pressure motor is divided into two parts：A part, which directly drives chain active rotation wheel, makes cutting chain movement be cut
It cuts, another part makes chain cutter runing rest be rotated by the deceleration conversion of planetary gear, and cutter is made to have feed motion, liquid
Pressure motor is driven by hydraulic oil, have overload protection, stepless time adjustment, light-weight, easy to automate, stable working,
It is easy to turn to, stops, quick the features such as starting, the input and output side for changing hydraulic motor need to be only controlled when completing cutting task
To, so that it may so that the direction of rotation of chain cutter runing rest changes, by change hydraulic oil into hydraulic motor
Speed, so that it may which, to change cutting speed of the cutter to the trees of different-diameter, wide adaptation range, control are simple, whole device knot
Structure is compact, is easily mounted on the vehicle arrangement of field work, this device can also be mounted on other timber cutting equipments, be answered
With having a extensive future.
