Abstract
A channel baler including a pressure channel, a plunger located in the pressure channel, a thrust crank drive for reciprocating the plunger in the pressure channel, and an element which provides for elastic yielding of at least one element of a pressure system including the pressure channel, the plunger and the thrust crank drive, in an axial direction by a path corresponding approximately to a thickness of a compressed bale upon a plunger power exceeding a predetermined value.
Claims2
A channel baler for forming bales of a compressible material, comprising a pressure channel;
- a plunger located in the pressure channel and displaceable therein in a pressing direction for compressing the material delivered into the pressure channel and in a direction opposite to the pressing direction;
- a thrust crank drive for reciprocating the plunger between the pressing direction and the direction opposite to the pressing direction;
- and means for providing elastic yielding of at least one of the pressure channel, the plunger, and the thrust crank drive in the direction opposite to the pressing direction by a path sufficient for releasing a force applied to the plunger upon a plunger power exceeding a predetermined value, wherein the elastic yielding providing means comprises an elastic intermediate member which connects the thrust rank drive with a baler frame and provides for a pivotal movement of the thrust crank drive in the direction opposite to the pressing direction upon the plunger force exceeding the predetermined value.
