Abstract:
A belt baler (1) for forming a cylindrical bale of fodder material comprises a pair of spaced apart side walls (10) formed by respective forward portions (14), and rearward portions (15) which form a tailgate (17). An endless compression belt (18) is carried on a series of support rollers (20) within the side walls (10) and is driven in the direction of the arrow C. As fodder material is fed into the baler (1) through a primary inlet (35) against the compression belt (18), the compression belt (18) commences to form a bale forming chamber (22) of progressively increasing diameter within which the cylindrical bale of fodder material is rotated by the compression belt (18) to form a bale. A deflecting roller (42) is rotatably carried on a pair of spaced apart carrier plates (43) and is rotated in the direction of the arrow G. The carrier plates (43) are pivotally mounted in the side walls (10) for urging the deflecting roller (42) from a deflecting position illustrated in Fig. 2 for deflecting netting material (39) from a dispenser (38) into a binding material inlet (37) to the bale forming chamber (37), to an idle position spaced apart from the binding material inlet (37), so that fodder material which is urged through the binding material inlet (37) by the compression belt (18) during formation of a bale can fall downwardly between the deflecting roller (42) in the idle state and the binding material inlet (37).
Abstract:
A baler (1) comprising a housing (10) having a stationary part (12) and a moveable part (14), both of which carry bale rotating rollers (20) which define a bale forming chamber (16) within which a bale (2) of forage material is formed and circumferentially wrapped with wrapping film (3). Monitoring apparatus (4) for detecting correct circumferential wrapping of the bale (2) in the bale forming chamber (16) comprises a pressure transducer (66) which monitors pressure in a pair of hydraulic rams (43) which urge the stationary part (12) and the moveable part (14) of the housing (10) together during formation and wrapping of the bale (2) in the bale forming chamber (16). On the pressure detected by the pressure transducer (66) being indicative of a reduction of the radial outward pressure being exerted by the bale on the bale rotating rollers (20) being greater than a predefined pressure drop, which corresponds to correct circumferential wrapping of the bale (2), a signal processor (67) which reads signals from the pressure transducer (66) produces a signal indicative of correct circumferential wrapping of the bale so that circumferential wrapping of the bale can continue.
Abstract:
Baling apparatus (1 ) for forming a bale (2) of grass, hay, straw or the like and for wrapping the bale (2) in non-perforated plastics sheet wrapping material (64, 71 ) comprises a chassis (10), a baler (16) mounted on the chassis (10) within which the bale (2) is formed, and a pair of bale supporting rollers (54, 55) on which the bale is supported and rotated during wrapping. An upper segment (21) and a lower segment (22) of the baler (16) are pivotal upwardly for transferring a bale from the baler (16) to the bale supporting rollers (54, 55). A first dispenser (63) and a holding mechanism (65) extend wrapping material (64) across a discharge opening (40) through which the bale (2) is transferred from the baler (16) so that as the bale is being transferred onto the bale supporting rollers (54, 55), wrapping sheet material (64) is drawn from the first dispenser (63) around approximately 180° of the circumferential surface (5) of the bale (2) and extends around corner edges (8) of the bale (2). The bale supporting rollers (54, 55) rotate the bale (2) for wrapping an appropriate number of turns of the wrapping material (64) around the circumferential surface (5) of the bale (2), and a carrier ring member (74) which carries second dispensers (72, 73) revolves the second dispensers (72, 73) about the bale (2) while the bale (2) is being rotated by the bale supporting rollers (54, 55) for wrapping of the bale (2) with wrapping material (71 ) from the second dispensers (72, 73). A bale wrapper is also disclosed.
