摘要:
A baler (10) comprising a bale chamber (26); a plunger (30) configured to compress crop material in said bale chamber (26) in order to form a bale; a needle yoke (42) with a plurality of needles (36) configured to deliver twine through said bale chamber (26); a plurality of knotters (34) configured to receive the twine from said plurality of needles (36); a bale length measurement and trigger device (150) configured to measure the length of the bale in the bale chamber (26) and to generate a trigger when a predetermined length is reached; a driving shaft (90) located above the bale chamber (26) and extending in a traverse direction of the baler (10); a needle coupling device (100) between the driving shaft (90) and the needle yoke (42), said needle coupling device (100) being configured for moving said needle yoke (42) from a rest position to a twine delivery position and back, when said bale length measurement and trigger device (150) generates a trigger
摘要:
An agricultural baler (10) includes a main bale chamber (26) extending in a bale forming direction (102) from an inlet end (104) to an outlet end (32). The main bale chamber (26) includes a plurality of stationary walls (106, 110, 112) and a plurality of movable density doors (120) positioned downstream from the stationary walls (106, 110, 112), relative to the bale forming direction (102). The stationary walls include a ceiling (106), a first side wall (110) and a second side wall (112). A plunger (30) compresses and moves the crop material from the inlet end (104) towards the outlet end (32) of the bale chamber (26). The baler (10) is characterized in that the first side wall (110), the second side wall (112) and/or the ceiling (106) comprises a constriction surface (100, 130), which constricts the main bale chamber (26) in a direction transverse to the bale forming direction (102).
摘要:
A rectangular baler comprising a bale chamber delimited by a plurality of walls including a movable wall section, an actuator for exerting a pressure on the movable wall section, a plunger for compressing crop material in the bale chamber, and a density control system comprising: a position calculating module configured to calculate a new position for the movable wall section based on an input representative for bale density of compressed crop material in the bale chamber; and a position control module configured to control the actuator to position the movable wall section in the calculated position.
摘要:
A baler (10) comprising a bale chamber (26); a plunger (30) to compress crop material in said bale chamber (26) to form a bale; a plurality of knotters (34); a needle yoke (42) with a plurality of needles (36) to deliver a plurality of lower strands through said bale chamber (26) to said plurality of knotters (34); a tucker arm shaft (190) carrying a plurality of tucker arms (195) to deliver a plurality of upper strands to said plurality of knotters (34); a driving shaft (90) located above the bale chamber (26) and extending in a traverse direction of the baler (10); wherein the tucker arm shaft (190) extends parallel to the driving shaft (90); a tucker arm (195) coupling device to convert the rotation of the driving shaft (90) into a rotation of the tucker arm shaft (190); a needle coupling device (100) to convert a rotation of the driving shaft (90) into a movement of the needle yoke (42) from a rest position to a twine delivery position and back.
