Abstract
A lump peat machine mills peat by means of a rotating cutter which delivers the peat to a tube containing a screw conveyor for expression through a nozzle onto the ground. The cutter is raised and lowered through means of a hollow arm supporting the cutter at one end and mounted on the tube by means of an encircling bearing at the other end. The power train for the cutter is positioned within the hollow arm.
Claims21
In a lump peat machine which mills peat from peatland by a rotating milling cutter which delivers milled peat to a tube having a screw conveyor disposed therein to express the peat through a nozzle to the surface, the improvement comprising means for raising and lowering the milling cutter comprising a hollow arm supporting said milling cutter at one end and affixed to a bearing at the other end, said bearing encircling said tube and being adapted to permit raising or lowering of said milling cutter between working and transport positions and means within said hollow arm to transmit power to said milling cutter.
In a lump peat machine which mills peat from a peat bog comprising a rotating milling cutter for cutting said peat, the cutter having a power source, said peat machine being adapted for coupling to motive means for driving the peat machine through the peat bog, said motive means having a throttle for adjusting its speed, the improvement comprising providing means for coupling the cutter to the motive means through an elastic member which engages in length to permit the distance between the cutter and said motive means to change from an original distance when said milling cutter meets increased resistance, said elastic member being operatively connected to said throttle whereby the throttle is displaced from a previously fixed position when the milling cutter meets increased resistance and the elastic member changes in length to reduce the speed of or halt said motive means, said elastic member being adapted to cause said cutter to move to restore the original distance between the cutter and the motive means when said motive means has been slowed or halted by operation of said elastic member until said increased resistance has been overcome and whereby said throttle is returned to said predetermined position.
