摘要： A rotatable forage harvester cutterhead having a rotatable shaft, and a plurality of axially spaced disc shaped plate members having substantially the same diameters and affixed in parallel planes transversely along the shaft for rotation therewith. A plurality of mounting members are detachably secured to the plate members for mounting a drum having an inner surface having a diameter at least as great as the diameters of the disc shaped plate members. Attachment means are employed for detachably securing the drum to the mounting members. Each of a plurality of substantially flat knives with a cutting edge extending in a transverse direction less than half the axial length of the drum are mounted on knife support assemblies comprising support blocks. The attachment means for securing the drum to the discs also secures the knife support blocks to the outer surface of the drum. Fasteners secure the knives to the blocks with the cutting edges extending in the direction of rotation of the cutterhead and generating a cylinder, under conditions where the cutterhead rotates, having a diameter larger than the diameter of the drum.

摘要： A method of forming bales in a round baler having a crop pickup and a bale forming chamber which is either fixed or expandable during bale formation. In one baler in which the method is readily carried out, the chamber is defined by a flexible apron comprising a plurality of side by side elongated belts trained about a plurality of rolls, a series of transverse crop engaging rolls and a floor roll. The method includes the steps of positioning the round baler to pick up crop material with the pickup, feeding the picked up crop material into the expandable bale forming chamber, sensing the compaction of the crop material in one or more regions during its formation in the bale forming chamber, generating a signal indicative of the level of compaction of the crop material in the region or regions, and repositioning the round baler in response to variations in the signal during expansion of the chamber to maintain the compaction at a predetermined level.

摘要： A rotatable cutterhead for a forage harvester having a plurality of parallel support members within plans perpendicular to a central shaft and spaced axially therealong. A plurality of similar chopping blades are affixed in circumferentially spaced relationship to each other around the support members, whereby the interior of said cutterhead is open and susceptible to ingress of cut forage material. Baffle strips extend from each blade inwardly from and adjacent the cutting edge at a sufficient distance and angle to deter the ingress of cut material into the interior of said cutterhead.

摘要： A method of wrapping cylindrical bales of crop material with netting material for use with apparatus including a feed roller which may be selectively driven to dispense the netting material from a supply roll into a round baler. The apparatus has a home position and a cutting position wherein the feed roller is latched. The apparatus also has a feeding position wherein the feed roller is driven. The method includes the steps of latching the feed roller when the apparatus is in the home position, unlatching the feed roller when the apparatus is moved from the home position to the feeding position, relatching the feed roller when the apparatus is moved from the feeding position to the cutting position, and maintaining the feed roller latched as the apparatus is moved from the cutting position to the home position.

摘要： A system for tensioning the apron of a round baler includes a pair of springs and a pair of hydraulic cylinders connected between apron take up arms and a tailgate of the round baler. The springs normally urge the apron take up arms toward an inner position, and the hydraulic cylinders resist movement of the apron take up arms from the inner position to an outer position. The hydraulic cylinders provide a primary source of apron tension and the springs provide a secondary source of apron tension. During bale formation, the apron tension generated by the hydraulic cylinders increases while the apron tension generated by the springs remains substantially constant.

摘要： A system for controlling the density of bales formed in a round baler includes a hydraulic cylinder unit of the single acting type connected between the frame of the round baler and a pair of arms which are pivotally mounted on the baler frame. These arms carry a set of conveying members or rollers and are movable between a bale starting position and a full bale position. The bale density control system includes a control valve that is adjustable in order to permit fluid flow from the hydraulic cylinder unit to a reservoir when the fluid pressure in the hydraulic cylinder unit reaches a preselected level. When the arms move from their bale starting position to their full bale position, the hydraulic cylinder unit is contracted and fluid flows from the hydraulic cylinder unit to the reservoir via the control valve when the preselected level of fluid pressure is reached. Conversely, when the arms move from their full bale position to their bale starting position, the hydraulic cylinder unit is extended and fluid flows from the reservoir to the hydraulic cylinder unit via a one way check valve.
摘要翻译：用于控制在圆形打捆机中形成的捆的密度的系统包括连接在圆形打捆机的框架之间的单作用型液压缸单元和可枢转地安装在打包机框架上的一对臂。这些胳膊携带一组传送部件或辊子，并且可以在打包起始位置和全包位置之间移动。捆包密度控制系统包括可调节的控制阀，以便当液压缸单元中的流体压力达到预定水平时，允许流体从液压缸单元流到储存器。当手臂从捆包起始位置移动到其完全打捆位置时，液压缸单元收缩，并且当达到预定的液压水平时，流体通过控制阀从液压缸单元流到储存器。相反，当手臂从其全包位置移动到捆包起始位置时，液压缸单元延伸，并且流体通过单向止回阀从储存器流到液压缸单元。

摘要： Quick or instantaneous stopping of rapidly rotating members places severe stress loads on components. These loads are substantially reduced by providing a quick-stopping apparatus including a damped member having an attached element which is movable into engagement with a rotating member. In response to such engagement, the energy of the rotating member is rapidly decelerated through the damped member thus reducing peak stress loads associated with almost instantaneous deceleration.

摘要： The device consists of a tapered spline coupler for a drive shaft of a pull-type forage harvester. The first drive shaft and second drive shaft each have a set of tapered splines that are inserted into a tapered, internally splined coupler. A pair of retaining rings affixed to the drive shafts draws the shafts into the coupler. A retaining bolt may be tightened to force the shafts into the coupler. A method for manufacturing the spline coupling consists of a cutting a groove in the drive shafts for a retaining ring. Tapered splines are cut onto the drive shafts. A tapered bore in the coupler is cut on a lathe by a boring bar. Splines in the coupler are created by use of a broaching tool. After the retaining rings are placed on the drive shafts, a retaining bolt tightens the assembly.
