摘要： A working machine may include: a conversion mechanism configured to convert motion of a prime mover; a first blade connected to the conversion mechanism; a second blade overlapping with the first blade in an up-down direction and facing a first facing surface of the first blade; a sealing member engaged with a first non-facing surface of the first blade that is opposite to the first facing surface, wherein the sealing member includes a first sealing surface facing the first non-facing surface in the up-down direction; and a cover member facing a second sealing surface of the sealing member that is opposite to the first sealing surface of the sealing member. The sealing member may be disposed forward of the conversion mechanism and configured to suppress the object cut with the first blade and the second blade from moving toward the conversion mechanism between the first blade and the cover member.

摘要： A tool head for a hand-guided implement possesses two rotatably mounted tools, wherein a first tool is drivable via a first linkage and a second tool is drivable via a second linkage. The tools are drivable so that they rotate back and forth in opposite directions about a common rotational axis. The first linkage possesses a first drive member coupled to a first coupling member pivotably about a first link axis. The first coupling member is coupled to the first tool pivotably about a second link axis. The second linkage possesses a second drive member coupled to a second coupling member pivotably about a third link axis. The second coupling member is coupled to the second tool pivotably about a fourth link axis. The rotational axis of the tools and the coupling drive axis span a center plane, which runs between the second link axis and the fourth link axis.

摘要： A mowing sickle drive system comprises a knife bar supported by a frame and drive apparatus operable to drive the knife bar in a reciprocating linear motion at a variable drive frequency. A spring is coupled to the knife bar for applying a restoring force to the knife bar toward a neutral position when in motion. The spring has a variable modulus of elasticity that is controlled dependent upon the drive frequency.

摘要： A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

摘要： A draper seal for a crop harvesting header is provided. The header includes a forwardly disposed cutter bar assembly and a rearwardly disposed draper deck assembly. The draper seal includes a flexible strip that runs parallel to the cutter bar assembly and perpendicular to the direction of travel. A bracket secures the forward edge of the flexible strip to an upper surface of the cutter bar assembly, which bracket also biases a rearward edge of the flexible strip into engagement with an upper surface of the draper deck assembly, thereby creating a seal between the cutter bar assembly and the draper deck assembly.

摘要： A header for an agricultural vehicle. The header includes a header frame and an elongate sickle knife mounted along a leading edge of the header. The header further includes an actuator for reciprocally moving the elongate sickle knife in its longitudinal direction relative to the header frame between a first position and a second position over an intermediate position. At least one accumulator extends between the header frame and the elongate sickle knife to accumulate energy during a first movement of the elongate sickle knife from the intermediate position towards at least one of the first position and the second position, and to release accumulated energy during a second movement of the elongate sickle knife opposite to the first movement.

摘要： A crop ramp and belt support component for an agricultural harvesting head is provided. The crop ramp and belt support component includes a forward portion, a rear portion, and a belt support portion that are generally planar. The forward portion is inclined relative to the rear portion, and the rear portion extends from the forward portion. The belt support portion is substantially parallel to the rear portion and is configured to extend at least partially below an interior surface of a belt conveyor. The forward portion, the rear portion, and the belt support portion are fabricated as a unitary component.

摘要： The stripper is a flange member supported on the upright backboard of a crop harvesting header to span a gap between the backboard and a cross auger. The cross auger is supported above a draper on the header to assist in guiding the cut crop being conveyed by the draper to a central rear discharge of the header. The stripper flange member extends forwardly towards the cross auger at an upward inclination so as to be oriented at an angle of greater than 90 relative to a portion of the backboard of the header immediately below the stripper flange member. The stripper flange member is thus better oriented to guide cut crop which rises up the backboard to be deflected forwardly into the cross auger, instead of acting as a stop to accumulate cut crop thereon when the flange member is oriented perpendicularly to the backboard.
