Abstract
Disclosed is a mine roller for attachment to a military vehicle such as a tank. The mine roller includes a frame vertically swingably connected to the tank and a set of disks mounted to the frame for eccentric rotation thereon. A ground engagement annulus is rotatable on the outer diametrical surface of each disk to provide rolling contact between the mine roller and the ground. The frame of the mine roller extends no further from the tank than do the annuluses, thereby minimizing interference between the frame and the ground. The mine roller also has means to limit the swinging of the mine roller relative to the tank, the limiting means including a cantilever arm or spring fixed to the mine roller frame and engagable with the tank after the mine roller swings a predetermined amount.
Claims14
A mine roller attached to a military vehicle, comprising:
- a frame;
- means attached to the frame for connecting the mine roller to the vehicle;
- a transverse member fixed to the frame;
- a pair of parallel arms on the transverse frame member extending away from the vehicle;
- a transverse rod connected between the ends of the parallel arms remote from the transverse frame member;
- at least two disks mounted for eccentric rotation about the transverse rod;
- a ground engagement annulus rotatable on the outer periphery of each disk.
A mine roller and a mechanism for pivotally connecting the mine roller to a military tank, comprising:
- a pair of closely spaced bracket plates extending from the tank toward the mine roller, the plates defining elongate slots open toward the mine roller;
- a frame having a transverse frame member and an interleaf plate extending from the transverse frame member between the spaced bracket plates, the interleaf plate having transverse pins engagable with the slots in the bracket plates;
- a hook rotatably connected to one of the bracket plates, the hook swingable to a first position to engage one of the transverse pin and having a finger fixed thereto, whereby the finger rotates with the hook;
- a hydraulic cylinder fixed relative to the bracket plates, the cylinder having a lock pin extendable therefrom to engage the finger, thereby preventing the hook from disengaging the transverse pin.
- a pair of parallel arms on the transverse frame member extending away from the vehicle;
- a transverse rod connected between the ends of the parallel arms remote from the transverse member;
- at least two disks mounted for eccentric rotation about the transverse rod;
- a ground engagement annulus rotatable on the outer periphery of each disk.
- means for restricting the vertical swinging of the mine roller relative to the vehicle, the limiting means including a bumper arm extending from the frame to a zone between the vehicle and the ground.
