摘要： The mechanism, designed especially for use in an earth compacting drum, comprises a pair of concentrically-arranged, eccentrically-weighted elements, which are rotated in unison by means of a hydraulic motor. The mechanism is housed within an earth compacting drum, and the one eccentrically-weighted element is translatable, axially, and disengageable from a splined coupling, in order that it may be indexed to different rotary positions relative to the other eccentrically-weighted element. In this manner, vibratory amplitudes may be increased or decreased.

摘要： The invention comprises a scraper assembly, and a method of forming same, for mounting forwardly of a padfoot-type, earth-compactor drum for scraping earth, mud and clay accretion from between rows of the padfeet, as well as for scraping the same from the faces of the padfeet, and in an embodiment thereof, the assembly comprises an array of longitudinally disposed and parallel rows of teeth arranged with diverging angles therebetween for efficiently cleaning the padfeet in both rotatable directions of the drum. The teeth are secured firmly to an I-beam which extends across the front of the drum, and a mounting assembly, for a fluid-pressure cylinder, is fixed to the I-beam to control a dozer blade.

摘要： In the embodiment shown, the assembly comprises a pair of apertured weights mounted on a rotatable shaft, each of the weights having abutment surfaces one or another pairs of which close upon each other, depending upon the direction of shaft rotation. One of the weights is keyed to the shaft to rotate therewith; the other weight is freely rotatable relative to the shaft. Upon rotation of the shaft in a first direction, a first pair of the abutment surfaces engage, and the eccentricities of the weights then are so disposed as to produce a given-amplitude vibratory force. Upon rotation of the shaft in a contrary direction, a second pair of the abutment surfaces engage, and the eccentricities of the weights then are so disposed as to produce a vibratory force of a differing amplitude.

摘要： In a preferred embodiment of the invention a pair of shock plates are disposed in parallel, and substantially bi-planar, coupled together by elastomeric elements. One of the shock plates has a cut-out therein and the other has a limb extending into the cut-out and spaced apart from the sides thereof. The one shock plate is mounted to the drum bearing housing of the earth compactor, and the other shock plate is mounted to the frame. Accordingly, upon the drum being vibrated, or shocked, or otherwise displaced, the limb engages one or more sides of the cut-out, and the movement between the plates is thereby limited to a given distance, in order that the elastomeric coupling will not be unduly stretched, destroyed, or fatigued too early.
摘要翻译： 在本发明的优选实施例中，一对冲击板平行布置，并且基本上是双平面的，由弹性体元件联接在一起。 冲击板中的一个在其中具有切口，另一个具有延伸到切口中并与其侧面间隔开的四肢。 一个冲击板安装在压实机的滚筒轴承座上，另一个冲击板安装在框架上。 因此，在鼓被振动或震动或以其它方式移位时，肢体接合切口的一侧或多侧，并且因此将板之间的运动限制在给定的距离处，以使得弹性体联接不会 过早拉伸，毁坏或疲劳太早。
