摘要： A crop chopper for an agricultural machine has a rotor having a plurality of fingers displaceable on rotation of the rotor along the passage, and respective blades interleaved with the fingers and each having a front end pivoted about a horizontal axis and a rear edge formed with a rearwardly open notch so that crop pressed by the fingers between the blades is chopped and moved rearward along the passage. A rocker is pivotal about a horizontal axis and respective actuator plates juxtaposed with the rear edges of the blades are each formed with a rearwardly projecting arm. Respective abutment bodies on the plates are displaceable toward and away from the respective blades and respective springs braced between the bodies and the respective plates urge the bodies forward toward the blades. The plates are each pivotal about a horizontal axis between an active position with the respective body engaged against the respective rear edge and an inactive position with the respective body disengaged from the respective rear edge. Respective springs braced between the plates and the rocker pivot the plates on the rocker about the respective plate axis in a direction pulling the bodies away from the blades and pivot the blade arms downward. An abutment beam extends below the plates, and at least one actuator engaged with the rocker can pivot down the rocker and thereby press the rear arms against the abutment beam and bring the plates into the active positions.

摘要翻译： 一种用于农业机械的作物切碎机具有转子，该转子具有沿着通道转动的可转动的多个指状物，并且各个刀片与手指交错，并且每个刀片具有围绕水平轴线枢转的前端和形成有 向后开口的切口，使得由刀片之间的手指按压的裁剪被切碎并沿着通道向后移动。 摇杆围绕水平轴枢转，并且与叶片后缘并列的相应致动器板各自形成有向后突出的臂。 板上的各个邻接体能够朝向和远离相应的叶片移动，并且相应的弹簧支撑在主体之间，并且相应的板将主体朝着叶片向前推动。 这些板各自在水平轴线之间枢转，主动位置与相应的主体相对于相应的后边缘接合，并且在相应的主体与相应的后边缘脱离接合的非活动位置之间。 相应的弹簧支撑在板之间，并且摇杆围绕相应的板轴线枢转摇动板上的板，其方向是拉动身体远离叶片并将刀臂向下枢转的方向。 邻接梁在板下方延伸，并且与摇臂接合的至少一个致动器可以向下枢转摇臂，从而将后臂压靠在邻接梁上并使板进入活动位置。

摘要： A baler has a frame, a shaft extending on the frame along and rotatable about an axis, and a knotter having a sleeve-like hub rotationally fixed to the shaft and of a predetermined outer diameter. A support journaled on the hub is fixed to the frame and carries movable knotting parts. A rim ring surrounding the axis is formed of a main C-shaped part having arms spaced apart by a distance greater than the hub outer diameter and a bridge part between the arms and closing the main part. The rim ring also has formations engageable with the parts for actuating same. Fasteners releasably fix the rim ring on the hub.
