摘要： A trencher machine digging boom assembly having a mounting arrangement for the digging boom wherein the boom includes a boom attaching weldment that is pivotally mounted to a boom pivot casting. The boom pivot casting is rigidly mounted to a trencher frame with a drive motor being mounted to one end of the boom pivot casting and a planetary gearbox being mounted at its opposite end. The planetary gearbox and associated drive components for the digging chain may be disconnected to permit easy and convenient removal of the digging boom for replacing its pivot bearings. Further, the torque reactions of the drive train are maintained within the boom pivot casting and are not transferred to the lift components associated with the digging boom.
摘要翻译：一种具有用于挖掘吊架的安装装置的挖沟机挖掘吊架组件，其中吊臂包括枢转地安装到吊杆枢轴铸件的悬臂安装焊件。悬臂枢轴铸件刚性地安装到挖沟机框架上，其中驱动马达安装到悬臂枢轴铸件的一端，并且行星齿轮箱安装在其相对端。用于挖掘链的行星齿轮箱和相关联的驱动部件可以被断开，以允许容易且方便地移除挖掘起重臂来更换其枢转轴承。此外，传动系的扭矩反作用力保持在悬臂枢轴铸件中，并且不会传递到与挖掘吊杆相关的升降部件。

摘要： A dirt deflector overtravel mechanism for a digging boom assembly which permits raising and lowering of the dirt deflector when the deflector is impacted by a rock or the like. The dirt deflector is pivotally attached at one end to a frame. A deflector link is pivotally attached at one end to the boom frame and its opposite end supports the dirt deflector. The opposite end of the deflector link is also pivotally attached to an overtravel link which, in turn, is pivotally attached to the deflector such that it remains in close proximity to the deflector under normal conditions. When a large rock or the like is thrown against the dirt deflector by the digging chain, the deflector link and overtravel link move from a scissors-like position to a colinear position which permits the dirt deflector to be displaced thereby preventing breakage or damage to the deflector. After the impact and displacement of the dirt deflector, the deflector will automatically fall back into place under its own weight.
摘要翻译：用于挖掘吊杆组件的污物转向器超程机构，其允许当偏转器被岩石等撞击时，使污物偏转器升高和降低。污物偏转器在一端枢转地附接到框架。导流器连杆在一端可枢转地连接到起重臂框架，并且其相对端支撑污物偏转器。偏转器连杆的相对端也可枢转地附接到超行程连杆，该行程连杆又可枢转地附接到偏转器，使得其在正常条件下保持紧靠偏转器。当通过挖掘链将大的岩石或类似物抛向污物偏转器时，偏转器连杆和超行程连杆从剪刀状位置移动到共线位置，这允许污物偏转器被移位，从而防止破坏或损坏导流板在污物偏转器的冲击和位移之后，偏转器将自动地在自重的情况下回落到位。

摘要： A drive control is disclosed which is particularly useful for machines having a hydrostatic transmission or ground drive pump, such as a tractor. A shift assembly controls the input to the hydrostatic transmission, and it includes a shift lever which is movable by a bellcrank mechanism in opposite directions from a neutral position into forward or reverse. The drive control further includes a rocking foot pedal which is connected by an actuating linkage to both the shift lever and the hydrostatic transmission. The desired direction of operation is set with the shift assembly, and the speed of movement in the selected direction is proportional to the amount the foot pedal is depressed. The foot pedal assembly includes a heel tab actuator which can be used as a manual override for the purpose of braking by bringing the hydrostatic transmission back to neutral while maintaining the transmission in the selected directional position. An automatic override mechanism is also provided such that when the foot pedal is released, for any reason, the automatic override mechanism returns the hydrostatic transmission to neutral without affecting the directional position setting. A further feature of the invention resides in the selector plate for directional control which includes a projection for actuating a neutral start switch.
摘要翻译：公开了一种驱动控制器，其特别适用于具有液压传动或地面驱动泵（例如拖拉机）的机器。变速组件控制静液压变速器的输入，并且其包括变速杆，变速杆可通过曲拐机构从相对方向从中立位置向前或向后移动。驱动控制还包括摇动脚踏板，其通过致动联动件连接到变速杆和静液压传动两者。所需的操作方向由换档组件设定，所选方向的移动速度与踏板被压下的量成比例。脚踏板组件包括脚跟突片致动器，其可以通过使静液压传动回到空档而被用作手动超驰，同时将变速器保持在所选择的方向位置。还提供了一种自动超驰机构，使得当脚踏板被释放时，由于任何原因，自动超驰机构使静液压变速器返回中立而不影响方向位置设定。本发明的另一个特征在于用于方向控制的选择器板，其包括用于致动中立起动开关的突起。

摘要： A crumber mechanism including a crumber shoe mounted on a support boom for powered movement between operative and non-operative positions. A fluid powered motor coacts with a linkage mechanism to move the shoe between positions in response to operation of the motor. An automatic locking device releasably holds the crumber shoe in a working position. The automatic locking device includes a slidable lock which moves into locking coaction with a locking channel defined by the shoe in response to extension of the hydraulic motor.

摘要： A dual wheel mounting arrangement for material handling implements is disclosed which permits the second, outer wheel of the arrangement to be easily and quickly releasably affixed to the first, inner wheel of the arrangement. The connecting arrangement includes a plurality of spokes affixed to a rim portion of the second wheel assembly, and further includes a generally elongated removable wheel fastener which is adapted to coact with the spokes for securing the second wheel assembly to the first. An adapter bracket is adapted to be mounted in association with the first wheel assembly by its lug fasteners, with the adapter bracket being adapted to releasably receive the wheel fastener. In one embodiment of the invention, a plurality of openings are defined by the hub portion of the first wheel assembly, with the openings respectively receiving projecting portions of the spokes affixed to the rim of the second wheel assembly, thus operatively interconnecting the wheel assemblies in driving relation. In another embodiment, a modified adapter bracket is provided for mounting in association with the first wheel assembly, with the adapter bracket defining at least one opening which is adapted to receive a projecting poriton of one of the spokes affixed to the rim of the second wheel assembly.
