摘要： The invention relates to an apparatus for stacking rolling material, such as e.g. wood chips, bark or grain into a pile (10) and reclaiming from the pile (10) to a material-discharging conveyor (20) located below the storing point, which apparatus comprises a center column (30) that supports a stacker boom (40) and a reclaimer boom (50), an equalizing hopper (60), at least one conveyor (25) located in the equalizing hopper (60) for transmitting the material being discharged to the discharging conveyor (20). A characteristic feature of the apparatus is that the center column (30) is supported directly through the equalizing hopper (60) onto the bottom of the equalizing hopper's (60) foundation.

摘要： An apparatus for reducing the oversized fraction of chips, especially the overthick fraction, which apparatus comprises a rotatingly fitted disc-like rotor part (1) to which is attached a number of chipping blades (2), and a fixed stator part (3) surrounding the rotor part (1), to which stator part is attached a number of counter blades (4), the blades (2) and counter blades (4) being arranged in chipping chambers (5), through which the chips to be reduced are arranged to travel outward with respect to the rotating shaft (6) of the rotor part (1). The counter blades (4) are fitted in a position substantially deviating from the radial direction of the rotating shaft (6), when viewed on the vertical plane with respect to the rotating shaft (6) of the rotor part (1). The chipping chamber (5) is formed by the space between two counter blades (4), the bottom surface (10) of which space is formed by the top surface of the rotor part (1), and the roof surface (11) by the bottom surface of the stator part (3) and counter blade (4) opposite to the top surface of the rotor part (1), whereby, when viewed in the direction of rotation (12) of the rotor part (1), the said roof surface (11) is arranged to converge towards the said bottom surface (10).

摘要： A knife (12) are a holding and releasing mechanism (8) are oriented in the direction of a radius of a chipper disc (19). The holding and releasing mechanism (8) is pushed in the direction of the radius of the chipper disc to release the knife (12) and drawn in the opposite direction to fasten the knife in the chipper disc (19). The time consumed in replacing the knives is reduced and laborious manual operations can be avoided. The procedure can be automated.

摘要： A device is disclosed for separating hard objects, such as stones, from a stream of wood in an apparatus for conveying or manipulating logs or blocks of wood including a conveyor section. The device includes a transducer disposed in a location suited for the detection of vibration. The transducer registers acoustic vibrations and is connected to a control unit by means of which hard objects conveyed along with the wood stream can be detected on the basis of the vibration signals they generate. The control unit is also used to control an exit gear incorporated in the conveyor section, so that hard objects which are detected will fall down from the stream of wood passing through the apparatus. The invention eliminates the need to build water-operated stone catchers as conventionally used for the removal of stones.
