  • Patent number: 8864561
    Abstract: The invention concerns a harvested crop residue chopper and distribution arrangement for a combine (10) with a straw chopper (60) with a rotor (74) that can be brought into rotation about a horizontal axis (98) with chopper blades (76) fastened thereto that define an outer envelope (96), and with at least one impeller blower (82) arranged downstream of the straw chopper (60) with impeller blades (84) that can rotate about an axis of rotation (88) that extends vertically, in which the impeller blades (84) are provided with outer edges (94) that conform to the envelope (96) of the chopper knives (76) and follow it very closely and are not in contact with it.

  • Patent number: 8146336
    Abstract: A harvested crop residue chopper-and distribution arrangement for a combine (10) has a straw chopper (60) with an outlet (80) arranged in the plane of the outlet (96), with at least one impeller blower (82) arranged downstream of the outlet (80) of the straw chopper (60) with impeller blades (84) that can be rotated in the plane of the impeller blower (98) about an axis of rotation (88), where the plane of the impeller blower (98) may be inclined relative to the plane of the outlet (96). The impeller blades (84) may be connected with a central body (92) that is connected to a cone (94) facing the outlet (80) of the straw chopper (60).

  • Patent number: 7717779
    Abstract: The invention concerns a combine (10) with a chassis (12) that can be moved across a field in the forward operating direction, a harvested crop processing arrangement (26) with an outlet (62) for straw and a straw chopper (60) with an inlet for straw (58). A rotating conveyor drum (68) is attached downstream of the outlet (62) of the harvested crop processing arrangement (26) and upstream of the inlet (58) of the straw chopper (60) that rotates in a first direction of rotation in the swath deposit operating mode and that conveys the straw received from the harvested crop processing arrangement (26) past the straw chopper (60) to the ground, and conveys it in the chopper operating mode in the second direction of rotation into the inlet (58) of the straw chopper (60).

  • Patent number: 7544127
    Abstract: A straw chopper for an agricultural harvesting machine includes a housing, a rotor carried by the housing, and a stationary knife bank. The rotor includes a plurality of pendulously mounted knife blades. The stationary knife bank includes a plurality of stationary knife blades adjustably movable toward and away from the rotor. The stationary knife bank includes a tension rod extending longitudinally through the stationary knife bank and having a threaded end, and at least one wing nut threadingly engaged with the threaded end.

  • Patent number: 7104883
    Abstract: A straw chopper blade comprising a flat blade defining a plane. The blade has a leading edge and a trailing edge. The leading edge is provided with a sharpened cutting edge that extends from the tip of the blade radially inward towards its mounting assembly. The leading edge is also provided with a paddle that extends perpendicular from the blade adjacent to the mounting assembly.

  • Patent number: 6692352
    Abstract: Rigid cover panels of the cover for grain storage tubes on combines, harvesting machine, are preferably fabricated of double-wall plastic to limit weight of the cover while providing desired strength and rigidity. The rigid cover panels can be pivoted about top edges of an underlying grain tank whereby the cover panels function as a height extension of the underlying tank, thus to increase the grain-carrying capacity of the tank. Flexible transition panels are preferably mounted to the rigid cover panels to bridge spaces between edge regions of the rigid cover panels when the rigid cover panels are raised to their upright, tank-extending orientations. A preferably single underlying actuator in the tank, in combination with mechanical linkages, can simultaneously raise all the rigid cover panels, all the flexible transition panels, and the discharge end of a clean grain elevator which discharges grain into the tank.
