    • An agricultural vehicle (10) comprising a bale chamber (26) includes: a plurality of movable density doors (210A, 210B, 210C); at least one fluid cylinder (220A, 220B) including a fluid chamber (322A, 322B), a piston (323A, 323B) disposed in the fluid chamber (322A, 322B) to separate the fluid chamber (322A, 322B) into a piston side (324A, 324B) and a rod side (325A, 325B), and a cylinder rod (221A, 221B) coupled to the piston (323A, 323B) on the rod side (325A, 325B) and configured to move at least one of the density doors (210A, 210B, 210C); and a fluid supply circuit (300) fluidly coupled to the fluid chamber (322A, 322B) and configured to supply working fluid to the fluid chamber (322A, 322B); wherein the at least one fluid cylinder (220A, 220B) further includes a piston fluid port (326A, 326B) that fluidly couples the piston side (324A, 324B) of the fluid chamber (322A, 322B) to the fluid supply circuit (300) and a rod fluid port (327A, 327B) that fluidly couples the rod side (325A, 325B) of the fluid chamber (322A, 322B) to the fluid supply circuit (300); and the fluid supply circuit (300) further includes a fluid supply controller (310) that is selectively switchable to a first fluid supply mode and a second fluid supply mode, the fluid supply circuit (300) being configured to supply working fluid to only the piston side (324A, 324B) of the fluid chamber (322A, 322B) when the fluid supply controller (310) is in the first fluid supply mode and to supply working fluid to both the piston side (324A, 324B) and the rod side (325A, 325B) of the fluid chamber (322A, 322B) when the fluid supply controller (310) is in the second fluid supply mode.

    • An agricultural baler (10) has a bale chamber (26) for the compression of crop into bales with a floor (42), ceiling (44), and two walls (46, 48). A plunger (30) forces crop into the bale chamber (26). An actuator system (50) presses the ceiling (44) and walls (46, 48) of the bale chamber (26) inward. At least one retractable friction block (72) in the ceiling (44) or walls (46, 48) is used to increase the compression and density of the crop. The friction blocks (72) extends inwards as an increasing function of either decreased pressure being exerted against the ceiling (44) or walls (46, 48) by the crop being baled, or inward displacement of the ceiling (44) or walls (46, 48) by the actuator system (50).
    • 农业打捆机(10)具有用于将作物压缩成具有地板(42),天花板(44)和两个壁(46,48)的捆包的捆包室(26)。 柱塞(30)迫使作物进入捆包室(26)。 致动器系统(50)将捆包室(26)的顶板(44)和壁(46,48)向内挤压。 天花板(44)或壁(46,48)中的至少一个伸缩摩擦块(72)用于增加作物的压缩和密度。 摩擦块(72)向内延伸,作为增加的作用是减少的压力被作物打包的天花板(44)或壁(46,48)施加,或天花板(44)或壁(46)的向内位移 ,48)通过致动器系统(50)。
