Machine for receiving and compressing agricultural harvested crops

Abstract

A machine for receiving and compressing agricultural harvested crops, such as hay, straw or grass, to roll-shaped bales with a coiling chamber, which can be swung open and moved by means of a chassis comprises a front chamber housing and a rear chamber housing, which is coupled pivotably to the front chamber housing for forming the boundary of a front and a rear bale-forming space. A first bale conveyor is allocated to the front bale-forming space and a second bale conveyor, which can be caused to move in a direction of rotation opposite to that of the first bale conveyor, is allocated to the rear bale-forming space. The first bale conveyor and the second bale conveyor are guided over at least one upper and one lower stationary deflector rolls which are supported so that they can rotate at the housing wall parts. At the mutually facing, inner upper and lower halves of the first and second bale conveyors, an inner tension guide roll can be applied, which can be transferred from a starting position with increasing bale size against the force of a tension force generator of a bale conveyor tensioning apparatus into an elevated tension guide position. Particularly in order to have a machine with a variable bale-forming space, with which harvested crops in the cut shape can also be molded in a structurally simple manner, the harvested crops conveyor has a cutting apparatus having cutting knives, which are disposed next to one another, are secured pivotably, can be acted upon with a spring force and can be transferred from an initial cutting position into a cutting position by means of a switching mechanism as a function of the operating position of a tension and compensating roller or a tension guide roller.
