End is connected by bearing pin with tension pulley support, other end connection wire rod, and screw mandrel passes through oil cylinder revolving bed, oil cylinder revolving bed to be hinged on machine
On frame, spring on screw mandrel, is cased with, spring is fixed on the outside of oil cylinder revolving bed by securing member, and tension pulley support is hinged on frame
On, tensioning wheel is installed on tension pulley support, tensioning wheel is located at the top of transmission belt, and clutch oil cylinder is two-way cylinder, clutch
Oil cylinder connects hydraulic buttery valve by two oil pipes, and hydraulic buttery valve connects electric control handle by control line.
When machine startup works, drivewheel is rotated, and as transmission belt is in relaxed state, now follower is in separation shape
State.When electric control handle is combined, electric control handle is shunk by controlling hydraulic buttery valve work, clutch cylinder piston rod, pulls tensioning
Wheel support, tension pulley support tensioning transmission belt, now follower rotation.When electric control handle gets to released state, electric control handle leads to
The work of control hydraulic buttery valve is crossed, the elongation of clutch cylinder piston rod promotes tensioning wheel to be rotated up, is driven belt sag, follower
Stop operating.
Described transmission belt is located between drivewheel and driven pulley, and transmission belt bottom arranges supporting plate, and tensioning wheel is located at actively
Top position between wheel and driven pulley, supporting plate are located at the lower position between drivewheel and driven pulley.Supporting plate is taken up to transmission
To supporting role.
