Abstract:
A wrapping material brake release assembly, including a wrapping material dispenser roll mount pivotable between a first functional position to dispense material from a dispenser roll and a second access position to provide access to the dispenser roll. A brake assembly having a brake member is arranged to brake the dispenser roll when the mount is in the first functional position. A ramp-shaped lifting member is arranged to lift the brake member from the dispenser roll when the mount is pivoted from the first position to the second position. The roll mount includes a pivot plate arranged to pivot from the first to the second positions, and a shaft attached at one end to the pivot plate. The roll mount has a brake drum, and the brake member has a brake arm and a brake pad attached to the brake arm.
Abstract:
A large round baler is equipped with a device for wrapping a bale formed in the baling chamber of the baler with a web of plastic sheeting or net wrapping medium. A supply roll of the wrapping medium is located in a box mounted forward of the baling chamber for movement along a fore-and-aft extending guide rail between a standby position, wherein a free end of the wrapping medium is supported by a guide surface at a location spaced forward of the baling chamber, and a wrapping position, wherein the free end of the wrapping medium is located for being grabbed by rotating rollers and/or the formed bale so that a length of the wrapping medium is pulled from the supply roll as it is wrapped about the bale. A power operated brake operates on the supply roll so as to provide a constant tension in the wrapping medium during wrapping operation.
Abstract:
A round baling press for baling harvested crops has a device for storing a roll of netting web for binding bales. Stones and other foreign bodies thrown into the housing of the baling press can lead to breakdowns and damage to the mechanism for feeding netting web into the baling press. A flexible and plastic web, preferably made of transparent material, is used as an inexpensive and simple housing cover to prevent stones and foreign bodies from entering the housing of the baling press.
Abstract:
A round baler is disclosed as including an improved bale wrapping mechanism that provides positive feeding of the wrapper at the start of the wrapping cycle. The mechanism includes a shiftable frame carrying a pair of feed rollers, with one of the rollers being brought into engagement with a stretch of the belts moving toward the baling chamber when the frame is shifted to a starting position. The wrapping mechanism is configured so that the belt stretch and the one feed roller cooperatively define a nip that is located downstream along the wrapper path from the nip defined between the feed rollers. A cutting assembly is disposed to sever the wrapper at a point spaced downstream from the nip defined between the belt stretch and the one roller, thereby insuring the wrapper presents a free end that is trapped between the one roller and the belt stretch when the frame is moved to the starting position. The wrapper is consequently gripped between the belts and the one feed roller so as to be pulled from its supply.
Abstract:
The present invention relates to a round baler for agricultural crop material having a press chamber for pressing the crop material and a wrapping device for wrapping the fully pressed round bales of crop material, wherein the wrapping material is secured on a web roll. The web roll is provided with a brake rod acting on the outside diameter of the bale. The essential characteristics of the invention are that a brake rod is affixed to one lever arm of a two-armed pivot lever and the effective linkage point of a plurality of tension springs is positioned the other lever arm. The linkage point's position is automatically variable relation to a stationary pivot point of the pivot lever as a function of the respective diameter of the web roll.
Abstract:
A round baler comprising a baling chamber mounted on a main frame for forming cylindrical packages of crop material therein, the baling chamber being at least partially defined by a pair of side walls and an apron assembly having an inner run which is guided at the inside of a cylindrically shaped continuous wall, and an outer run which is guided at the outside of said continuous wall. The continuous wall is provided with an opening for the recuperation into the chamber of crop material which has been entrained by the apron assembly when the latter left the baling chamber and entered its outer run.
Abstract:
A method of wrapping crop material in a round baler having a main frame including opposing sidewalls, and an apron assembly comprising crop engaging elements disposed between said sidewalls for defining a bale forming chamber having a generally cylindrical shape with a transverse inlet. The crop engaging elements move along a path having an inner course contiguous with a major portion of the fixed periphery of the cylindrical chamber. The baler also includes a pickup assembly for feeding crop material to the chamber through the inlet whereby crop material accumulated in the chamber is engaged by the crop engaging elements and formed into a compacted cylindrical package. A supply of net material is dispensed into the chamber for wrapping the periphery of the formed cylindrical package of crop material in the chamber. A supply of twine is simultaneously dispensed into the chamber for wrapping the periphery of the cylindrical package of crop material. Cutting means severe the net while the twine is being dispensed into the chamber. Subsequently the twine is cut by the same cutting means.
Abstract:
An agricultural baler for making cylindrical bales of crop material having a sledge assembly moveable between bale starting and full bale positions. The sledge assembly includes a plurality of rollers which cooperate with an array of belts to define a bale forming chamber. A dispensing mechanism is provided for dispensing web material, such as net or the like, into the bale forming chamber whereupon it is wrapped circumferentially around a cylindrical package of crop material in the bale forming chamber. Included along the path of the net prior to being fed into the chamber is a severing assembly for cutting the net after it has been wrapped around the cylindrical hay package formed in the chamber. The net severing assembly includes a unique severing element that provides improved net cutting.
Abstract:
An apparatus and method are provided for wrapping roll material around a round bale within a bale forming chamber of a round baler including a drive belt tensioner idler, a wrapping material brake and a wrapping material cut-off knife all disposed on a carriage that is articulated between a wrapping material feeding position and a cut-off/stop position. When baling is completed, a signal is provided for movement to the feeding position at which time the wrapping material is held taught to maintain bale compression. After sensor data are fed back to a controller to signal feeding has proceeded for the desired length of time and/or to deploy the desired length of wrapping material, the device articulates to the cut-off position to sever the wrapping material to allow completion of the bale wrapping procedure. A crop recycling mechanism can also be provided to re-feed stray crop material into the baling chamber.
Abstract:
A supply of wrapping material for a wrapping mechanism is provided in the form of a spool having a core member which is rotatably mounted to the lower ends of a pair of support arms having their upper ends vertically pivotally mounted to an arm support for pivoting about a horizontal axis. An upright contact surface is located below the horizontal axis and is engaged by one side of the spool of material such that the surface offers frictional resistance to the unwrapping of material from the spool. In order to keep this frictional resistance substantially constant through out the unwrapping of material from and consequent loss of weight of the spool, a biasing spring may be connected between the arm support and at least one of the arms and/or the surface can be configured or coated with frictional material such that the coefficient of friction of the surface increases in a direction away from the horizontal axis, this being the direction that the zone of contact between the spool and the surface travels as wrapping material is pulled from the spool during wrapping operation.
