A large round baler includes bale-forming means conducted over rotary bodies with stationary axes and rotary bodies with movable axes so as to define an expansible circumference of a baling chamber. Some of the movable rotary bodies are mounted to a carrier mounted to fixed side walls defining opposite sides of the baling chamber. The carrier is pivotally mounted to opposite side walls defining opposite sides of the baling chamber for movement between a lowered operating position and a raised discharge position wherein it holds a span of the bale-forming means, which during operation, forms the rear portion of the circumference of the baling-chamber above the formed bale so that the latter may be discharged.
Abstract:
A bale wrapping implement includes a main frame supported on a caster wheel mounted at the center of gravity of the device. The main frame is coupled to the axle of a large round baler for vertical pivotal movement so that the wrapping implement is able to follow the contour of the ground. An auxiliary support wheel is mounted to the main frame so that it engages the ground only when the bale wrapping device is supporting a bale to be wrapped. The main frame includes first and second components which are pivotally coupled to each other and a linkage including an extensible and retractable hydraulic actuator is coupled so that a pair of parallel rolls carried by the second component are disposed in a location close to the discharge gate of the baler for receiving a bale when the actuator is extended and are located remote from the gate in a position for wrapping the bale, when the actuator is retracted.
Abstract:
A large round baler includes a chassis which forms a forward part of a baling chamber, with a rearward part of the chamber being formed by a bale discharge gate. The discharge gate is constructed of first and second, separate parts that are, either each separately pivotally connected to chassis or are mounted such that the second part is pivotally attached to the first part. The parts are arranged such that arms of the second part overlap the opposite sides of the first part. Different embodiments disclose various driving structures for causing one part to be moved by moving the other part, with the arrangement of the two parts resulting in the gate being quickly moved to its open position for discharging a bale.
Abstract:
A roll for use in defining a baling chamber of a large round baler includes a tubular central body having stub shafts projecting from opposite ends thereof and secured thereto at locations within opposite ends of the tubular body. In one embodiment, a flange is formed integrally with each stub shaft and is welded to a tubular cylindrical extension inserted into a respective end of the tubular central body and secured there either by a press fit and/or welding. In a second embodiment, a flange is integral with each tubular extension as well as with each stub shaft with the flanges of the stub shafts being respectively bolted to the flanges of the extensions.
Abstract:
A round baler is provided with a bale wrapping mechanism including a wrap material guide assembly comprising a guide pan having an operative position wherein a guide surface is disposed upwardly for guiding wrap material into the baling chamber by way of a gap existing between adjacent fixed rolls forming at least a portion of the baling chamber. The guide pan is mounted for pivoting vertically and shifting fore-and-aft for permitting it to move to a inoperative position wherein a majority of the guide surface is disposed near vertical with the remainder being steeply disposed so that crop material and dirt will not accumulate on the guide surface. A wrap material cutting device includes a knife assembly including a knife mounted between opposite arms and being pivotal between a stand-by position, wherein the knife is disposed below a feed path of the wrap material when the latter is passing through the gap into the bale chamber during wrapping of a bale, and a cutting position wherein it traverses the feed path. At least one coil extension spring is coupled between the knife assembly and the guide pan for causing the latter to be moved to its inoperative position whenever the knife is moved to its operative position and to be moved to its operative position whenever the knife is moved to its stand-by position.
Abstract:
A round baler includes a bale chamber defined in part by a plurality of belts mounted between opposite side walls of the baler and including an upright run located at the rear of the baler side walls and joined to a fore-and-aft extending run located at the bottom of the baler side walls. A binder arrangement is mounted to the rear and bottom of the side walls and includes a pair of feed rollers disposed in such close proximity to the upright runs of the belts that the kinetic energy imparted to the web of binder material being conveyed by the rollers carries it into contact with the upper run of belts which then carry the binder material downwardly into a fore-and-aft extending guide track that leads to the baling chamber. The binder arrangement includes cutting arrangement defined by a movable knife and a stationary counter knife, the movable knife being mounted for movement between a rest position located above a tangent extending from a passage formed by the rollers and forwardly of an upper one of the rollers, and a cut-off position located below the tangent and forwardly of a lower one of the rollers and the counter knife being mounted adjacent said cut-off position.
Abstract:
A large round baler having an expansible bale chamber has tension cylinders associated with the chamber for strongly resisting expansion thereof so as to produce dense bales when a bypass valve located in a bypass line interconnecting rod and piston ends of the tension cylinders is positioned for preventing flow through the valve thereby forcing the flow to go through a variable high pressure relief valve located in another bypass line, the bypass valve being selectively shiftable to another position for permitting free flow therethrough when it is desired to produce a soft bale. The baler also includes gate cylinders for opening and closing the discharge gate of the baler. These gate cylinders are connected in circuit with the tension cylinders and the bypass valve is connected to the piston ends of the gate cylinders in such a way as to prevent the gate cylinders from extending at a time when the gate has just been closed, such extension of the gate cylinders, if not prevented, resulting in the gate becoming unlatched.
Abstract:
This press for forming cylindrical or round bales comprises sets of bands or belts which, in a conventional manner, define a chamber for forming a bale by rolling up, as well as a pickup designed to transfer harvest products gathered on the ground as far as a bale-forming chamber through an entry opening for the products, and a starting roller located on that side of the opening that is remote from the pickup. According to the invention, a scraper is arranged to cooperate with the starting roller in such a manner as to resist any rolling up of the harvest products around the roller. If the roller is a smooth circular section roller, the scraper may be stationary. It may be arranged in conjunction with fingers extending between the bands or belts as far as to the immediate vicinity of the starting roller on the side of the roller remote from the scraper. In the case of a noncircular starting roller, the scraper is mounted so as to be movable, especially pivotable. It may be resiliently urged towards the starting roller, or else be positively displaced by a driving mechanism.
