摘要： A chopper has a housing centered on an axis and having a radially open input and a radially open output spaced angularly therefrom as well as a pair of axially oppositely open intakes, and a cutter drum rotatable in the housing about the axis and having a pair of end plates transverse of the axis and having axially oppositely directed faces confronting the respective intakes and a plurality of blades secured to and between the end plates and having cutting edges defining on rotation of the drum an orbit centered on the axis. Respective pluralities of vanes at the end plates can be secured either to the respective end plates in in-service positions extending generally radially thereon so that rotation of the drum moves the vanes to draw air in the axial intakes and expel it through the radial output or in an out-of-service position in which they do not move appreciable air. The vanes can be secured in the out-of-service position also to the respective end plates but extending generally only angularly. In particular the vanes form a radially closed cylindrical annulus in the out-of-service position. This annulus generally blocks flow from the intake to the output in the out-of-service position. The vanes can also be secured in the out-of service position so as not to rotate with the drum.

摘要： A baling machine according to the invention has a frame having walls defining an elongated compaction chamber having a front end provided with a transversely open intake to which a stream of crop is fed substantially continuously. At least one compacting member is periodically displaced in the chamber between a front position forward of the intake and a back position rearward of the intake by an appropriate drive so as to rearwardly compact crop in the chamber. A plurality of pushers are each displaceable between an advanced position projecting into the chamber and only partially blocking the intake and a retracted position substantially out of the chamber by a linkage that advances the pushers into their advanced position only when the member is rearward of the intake and of the pushers. Thus advance of the pushers into the advanced position immediately after movement of the compacting member rearward past the pushers parts the stream of crop between the pushers and compacting member. A plurality of tie needles engages across the chamber rearward of the pushers in the advanced position thereof so as to pull respective ties across only when the pushers are in the advanced position. Normally according to the invention each of the pushers is formed with a throughgoing guide hole and each of the needles can pass through a respective one of the holes in the advanced position of the respective pusher.
摘要翻译：根据本发明的打捆机具有框架，所述框架具有限定细长的压实室的壁，所述压实室的前端具有横向开放的进料口，所述作物料流基本连续地进入所述进料口。至少一个压实构件通过适当的驱动在腔室中的前部位置和进入口后方的后部位置之间周期性地移位，以便使腔室中的作物向后缩小。多个推动器各自可以在突出到腔室中的前进位置之间移动，并且仅通过使推动器进入其前进位置的联动件仅基本上部分地阻挡进气口和缩回位置，缩回位置仅在该构件在进气口后方时和推动者。因此，推压器在压紧构件向后移动通过推动器之后立即进入先进位置，将推动器和压实构件之间的作物流分配。多个连接针在推进器的后方穿过该腔室的前进位置，以便仅当推动器处于前进位置时拉动相应的连接件。通常根据本发明，每个推动器形成有穿过的引导孔，并且每个针可以穿过相应推动器的前进位置中的相应的一个孔。

摘要： An impeller-type cutter drum for a chopper has a drum body including three drum disks arranged side-by-side and supporting two rows of blade holders which are spaced about the circumference of the drum body. Each blade holder supports a chopping blade and extends between a respective one of the outer disks and the center disk upwardly in an upwardly inclined and oblique manner. The front portion of each blade holder is shaped as an impeller which is arranged at constant distance to and has corresponding inclination as the chopping blade. Each impeller has an arc-shaped deflector portion immediately adjacent the centered drum and extends in a plane approximately adapted to the plane of the drum shaft which support the disks.
