Patent number: 5205105Abstract: A machine for receiving and compressing agricultural harvested crops, such as hay, straw or grass, to roll-shaped bales with a coiling chamber, which can be swung open and moved by means of a chassis comprises a front chamber housing and a rear chamber housing, which is coupled pivotably to the front chamber housing for forming the boundary of a front and a rear bale-forming space. A first bale conveyor is allocated to the front bale-forming space and a second bale conveyor, which can be caused to move in a direction of rotation opposite to that of the first bale conveyor, is allocated to the rear bale-forming space. The first bale conveyor and the second bale conveyor are guided over at least one upper and one lower stationary deflector rolls which are supported so that they can rotate at the housing wall parts.Type: GrantFiled: February 10, 1992Date of Patent: April 27, 1993Assignee: Maschinenfabriken Bernard Krone GmbHInventors: Bernard Krone, Wilhelm Ahler

Patent number: 4771592Abstract: The invention relates to a machine which is pulled or attached to a three-point attachment on a tractor and used for the harvesting of corn or similar stalk-like crops. The machine has a cutting device and a chopping blower arranged subsequent thereto with slide-in rollers to which the crop is supplied by a cross-conveyor running transversely to the direction of travel of the tractor. The cross-conveyor is designed as a cutting and supplying device, cutting the crop at any point in the working area, holding it above the cut area and supplying it in an approximately upright or inclined position, opposite to the conveying direction, to the slide-in rollers or a chopping machine with simultaneous release.Type: GrantFiled: March 20, 1986Date of Patent: September 20, 1988Assignee: Maschinenfabriken Bernard Krone GmbHInventors: Bernard Krone, Wilhelm Ahler

Patent number: 4610123Abstract: An attachable apparatus for covering round bales of agricultural harvested goods with a section of a covering inside a molding chamber of a baling press includes a supply roll freely rotatable about a tranversal axis and having an adjustable braking force. The supply roll extends across the width of a housing parallel to the center axis of the press chamber. A pull-off device which initiates the starting phase of the covering process is located adjacent the opening where the goods to be harvested enter or a comparable slit is located in the housing of the press chamber. During the starting phase, the braking effect of the supply roll is considerably reduced or suspended.Type: GrantFiled: October 5, 1984Date of Patent: September 9, 1986Assignee: Maschinenfabriken Bernard Krone GmbHInventors: Bernard Krone, Wilhelm Ahler

Patent number: 4604855Abstract: Wrapping apparatus for use with a baling machine of the type having a forming chamber in which a round bale is formed and into which a wrapping material is fed to wrap the bale, includes a housing, a feeding device mounted on the housing for feeding a wrapping material from a source of wrapping material to the forming chamber, and a drive on the housing having a drive position for driving the feeding device, the drive being biased into a non-drive position so that the drive is disengaged from driving the feeding device. A cutter is provided for cutting the wrapping material after the wrapping material exits the feeding device, the cutter being movable between a first and a second position. A pivotal lever is operable between an initial position and a first operable position, the pivotal lever being movable from the initial position to the first operable position to actuate the drive from its non-drive to its drive position to thereby drive the feeding device to feed the wrapping material.Type: GrantFiled: May 7, 1984Date of Patent: August 12, 1986Assignee: Maschinenfabriken Bernard Krone GmbHInventors: Bernard Krone, Wilhelm Ahler

Patent number: 4212149Abstract: A crop baling machine of the kind for producing wound bales has a hollow cylindrical winding compartment having a bottom gap in the compartment cylindrical wall through which the crop is fed by a pick-up device. Conveying rollers then convey the crop to an endless slat conveyor a radially inner run of which is guided at its side edges to sweep round the inner, part cylindrical wall of the compartment. The outer run of the conveyor is guided round the outside of this wall. A rear compartment portion is hinged to open upwardly to release the bale. The construction is relatively simple and robust and requires less power than conventional machines because uniform radial compression of the bale is achieved. Also, dust and particles of crop cannot easily escape from the baling compartment.Type: GrantFiled: June 27, 1978Date of Patent: July 15, 1980Assignee: Maschinenfabriken Bernard Krone GmbHInventors: Bernard Krone, Wilhelm Ahler

Patent number: 4125987Abstract: A machine for cutting and harvesting of crops having stalks which is pulled by a tractor in a direction of travel. The machine includes a guide casing which has vertical cylindrical wall means. A vertical drum with gripper teeth is rotatably mounted on the guide casing and pulls the stalks of the crops into a pulling passage defined by the cylindrical surface of the drum and the vertical cylindrical wall means. A feed trough merges with the vertical wall means which extend from a 3-o'clock to an 8-o'clock position of the drum. A chaff blower having a pair of feed rollers is mounted at the outlet of the feed trough. The stalks of the crop are seized by the gripper teeth of the drum and transported through the pulling in passage where they are cut by cutting means and then are transported to the feed trough while assuming an increasingly rearwardly inclined position with respect to the direction of travel.Type: GrantFiled: October 1, 1976Date of Patent: November 21, 1978Assignee: Maschinenfabriken Bernard Krone GmbHInventors: Bernard Krone, Wilhelm Ahler
