摘要： An apparatus for feeding roundwood into a rotating debarking drum through the inlet end of the barking drum utilizing a conveyor. The prior method presents the drawback that it is not possible, with a single feed device, to feed into the barking drum roundwood of different lengths but only either long, intermediate-sized or short logs. With the present invention, this problem has been solved in that the logs are positively fed by the conveyor, at low speed, into the lower part of the barking drum, through a feed cylinder.

摘要： A hydraulic feed control system for log debarkers having three infeed and three outfeed rolls. Each roll is driven by its own hydraulic motor. Each infeed motor is connected in series with a corresponding outfeed motor whereby three pairs of motors are defined. The hydraulic fluid is pumped through a three way flow divider which divides the fluid equally to each of these pairs. Each of the motors has a special crossover relief with a directional flow control that will prevent the excessive pressure that may be created by one of the motors in the series from effecting the pressure to the other motors. The special relief is also provided with a direct line into the oil reservoir which if needed either of the motors in series may siphon oil from the reservoir through the directional flow control valve without affecting the other motor. The return line from the outfeed (down flow) motor joins a common return which is separate from the relief return to tank. When any of the motors for any reason is inadequately supplied with oil, the motor will act as a pump siphoning fluid from the tank. Additionally, any excess fluid flowing to a motor will drain through the relief system back to the tank. This system is also supplied with a separate return to reservoir.
摘要翻译： 一种具有三个进给和三个出料辊的对数剥皮机的液压进给控制系统。 每卷由自己的液压马达驱动。 每个进给电机与相应的输出电机串联连接，由此定义了三对电机。 液压油被泵送通过三通分流器，其将流体均匀地分配到这些对中的每一个。 每个电动机都具有特殊的交叉泄压，具有定向流量控制，可以防止串联中的一个电动机产生的过大的压力对其他电动机产生压力。 特殊排气口还设置有直接进入油槽的管线，如果需要，串联的任一个电机可以通过定向流量控制阀从储油器吸入油，而不影响其他电机。 来自出料（下流）马达的返回管路连接一个共同的回程，该回程与释放回油分离。 当由于任何原因导致任何电机供油不足时，电机将作为泵的虹吸液体。 此外，流入电动机的任何多余的液体将通过浮雕系统排回到油箱。 该系统还提供了一个独立的回水库。

摘要： The self-centering feeding device (20') for elongated objects such as logs includes a conveyor means (30) carried by a parallel mechanism having a vertical stationary part. The parallel mechanism is connected to a mechanical engagement means (26) and is controlled by a driving means (28) activated when an object on the conveyor means reaches a predetermined position, and is then kept activated the whole time during which the object is fed-through. The object is thus firmly clamped between the conveyor means and the engagement means and has no possibility to rotate about its longitudinal axis. The conveyor means may therefore be much shorter than the object. The invention is suitable for general application, but in particular for application in the log processing industry.

摘要： A feeding device for use with tree processing machines such as delimbing, barking and slashing machines wherein feed rolls are provided on each side of a feed path for the tree trunk. The feed rolls have a conical configuration and are mounted for rotation about axes inclined to each other at an angle equal to the base angle of the rolls. The surfaces of the feed rolls facing towards each other lie parallel and have a greater radial distance to the axis of rotation at the base portion of the feed rolls than at the upper portion thereof. This arrangement establishes a greater feeding force at the upper portion of the feed rolls than at the base portion and a circumferential speed for the feed rolls which is highest at the base portion and lowest at the upper portion thereby enabling tree trunks having relatively smaller diameters to be advanced through the rolls at relatively higher speeds.

摘要： A drum barker including a cylindrical drum having debarking means. The drum is supported by wheels on both sides, the wheels including elastic outer portions. A guide ring assembly is provided on the drum periphery for contacting wheel portions to resist axial drum movement. The guide ring assembly includes at least two guiding faces which extend obliquely from the drum periphery in a direction away from the wheel portions to reduce wearing of the wheel portions and to cushion the forces imparted during axial contact of the wheel portions and guide faces.

摘要： A shearing mechanism for a tree harvester having a pair of arms each carrying a weighted shear blade at one end and affixed at the other end to each of a pair of parallel shafts supported by the harvester with the shafts being rotated in opposite directions to move the arms between a first position in which the shear blades face outwardly in opposite directions from upwardly extending arms and a second position in which the shear blades face inwardly adjacent each other in opposite directions from downwardly extending arms.
