    摘要： A hay baler including an elongated bale chamber and a powerdriven plunger reciprocably mounted in the chamber for cyclically compressing hay in the chamber. Hay is fed into the chamber through a feed opening in a sidewall thereof by a feed mechanism operated in synchronization with reciprocating movement of the plunger. A knife is mounted on the sidewall adjacent to the feed opening. Another knife is mounted on the plunger so as to be movable thereby in close cutting relation with the sidewallmounted knife to cut the hay at the feed opening. The synchronized movement of the plunger and the feed mechanism is provided in part by a rack and pinion drive wherein an elongated rack is slidably mounted on the outside of the bale chamber and connected to the plunger for conjoint reciprocation. The rack drives a pinion which in turn drives the feed mechanism. Adjustment of the position of the knives relative to each other is accomplished from the outside of the bale chamber by shifting the rack, plunger, and attached knife to position the knife in proper cutting relation to the chamber-mounted knife.

    摘要翻译： 包括细长捆包室的干草打包机和可往复运动地安装在室中的动力驱动柱塞，用于循环地压缩室中的干草。 通过与柱塞的往复运动同步地操作的进给机构，将干草通过其侧壁中的进给开口进入腔室。 刀片安装在靠近进料口的侧壁上。 另一个刀片安装在柱塞上，以便与侧壁安装的刀具紧密地切割关系，以便在进给口处切割干草。 柱塞和进给机构的同步运动部分地由齿条和小齿轮驱动器提供，其中细长齿条可滑动地安装在捆包室的外部并且连接到柱塞用于联合往复运动。 齿条驱动小齿轮，从而驱动进给机构。 通过移动机架，柱塞和附接的刀来将刀的位置相对于彼此的调整从捆包室的外部实现，以将刀定位成与腔室安装刀相适应的切割关系。
