摘要： A mechanism for enveloping a large round bale with a surface wrap material such as plastic sheet or net includes a housing for holding a supply roll of the wrap material. The mechanism and, hence, the housing is mounted on the rear of a bale discharge gate. The housing includes a front wall, defined by an upright panel secured across the rear of the gate, and a bottom wall sloped upwardly and rearwardly relative to the front wall. The bottom wall and front wall converge toward a wrap material passage defined between a forward edge of the bottom wall and the front wall. The bottom wall is curved convexly upwardly between front and rear ends thereof, with the curvature and slope of the bottom wall being chosen such that a roll of wrap material resting on the bottom wall will become increasingly wedged against the front and bottom walls as the material is used and the weight and diameter of the roll decreases with the result that the braking force imposed on the roll will remain substantially constant no matter what the weight or size of the remaining roll.

The mechanism and, hence, the housing is mounted on the rear of a bale discharge gate. The housing includes a front wall defined by an upright panel secured across the rear of the gate and having an upper end portion projecting rearwardly and downwardly and a bottom wall spaced below the upper end portion of and being sloped upwardly and rearwardly relative to the front wall. The housing also includes a cover which is vertically pivotally mounted to a pair of brakets located just beneath the upper end portion of the front wall, the cover having a top wall having a forward edge portion which seals against the bottom of the upper end portion of the front wall when the cover is in a closed position. A pair of gas springs are connected between the cover and the brackets and have their line of action disposed relative to the pivot axis of the cover such that the cover is respectively biased to its closed and open positions when placed in these positions with the springs going over center as the cover is moved between the positions.

摘要： A large round baler is equipped with a wrapping mechanism for applying a web of plastic material to a bale located in the bale-forming chamber. The wrapping mechanism includes a housing including a cover mounted to the rear of the discharge gate of the baler for pivoting vertically, about a first horizontal transverse axis at an upper forward location of the cover, between a lowered closed position, wherein it encloses a roll of wrap material resting on a pair of roll end supports, and a raised position permitting access to the roll end supports. A pair of gas springs are coupled between opposite side walls of the cover and spaced apart crank arms of a load member which is vertically pivotally supported from the gate for swinging about a second horizontal transverse axis located slightly below and rearwardly of the first axis. The disposition of the gas springs relative to the first and second axes is such that the springs act to maintain a load bar of the load member urged into contact with a roll of wrap material supported on the roll end supports when the cover is in its closed position and acts to pivot the load member so as to dispose the load bar thereof in a raised inoperative position in response to the cover being raised to its open position, the springs also acting to maintain the cover in its raised position.

摘要： A mechanism for enveloping a large round bale with a surface wrap material such as plastic sheet or net includes a housing for holding a supply roll of the wrap material. The mechanism and, hence, the housing is mounted on the rear of a bale discharge gate. The housing includes a front wall, defined by an upright secured across the rear of the gate, and a bottom wall sloped upwardly and rearwardly relative to the front wall. The bottom wall and front wall converge toward a wrap material passage defined between a forward edge of the bottom wall and the front wall. A wrap material loading arm is vertically pivotally mounted to the support walls at locations adjacent the rear end of the bottom wall, the arm being shaped so as to be able to receive and cradle a supply roll in a relatively low position for ease in loading and for having a length of material pulled therefrom and placed around the forward part of a spreader roll of the material feed mechanism, when the arm is in a lowered roll-receiving position, and so as to deposit the cradled roll onto the bottom wall when the arm is lifted to a raised position.

摘要： A large round baler is equipped with a pickup having a reel provided with fixed tooth bars to which are mounted a plurality of teeth having tines projecting approximately radially outwardly from the axis of rotation of the reel. The fixed tines cooperate with the upper surface of a stripper assembly to convey crop directly into the inlet of a baling chamber and against an upwardly moving surface of a run of belts defining a rear wall of the chamber.
