Abstract:
The present disclosure relates to a wood chipper (20) including a support frame (22), a housing (24) mounted on the support frame (22), a cutter member (26) for chipping wood within the housing, and a discharge chute (29) for discharging wood chips from the housing. The wood chipper (20) also includes at least one resilient isolator (138) for dampening vibration between the engine (122) and the support frame and a moveable drive sheave. Alternatively the wood chipper also includes a first resilient isolator for dampening vibration between the housing and the support frame (22). Alternatively the wood chipper also includes a noise abating curtain. Alternatively the wood chipper also includes a controllable feed means (50).
Abstract:
A chip (16) and method for producing wood pulp. First (S1, S2), second (S5, S6) and third (S3, 54) pairs of substantially parallel sides are formed by cutting, cleaving and cutting, respectively. The sides of the first pair of sides (S1, S2) are cut by a first knife (10) so as to be spaced between about 2 to 8 mm. The sides of the third pair of sides (S3, S4) are cut by a second knife (22) so as to be spaced a greater distance apart than the first pair. The sides of the second pair of sides (S5, S6) are cleaved substantially along the grain direction (9) so as to spaced also a greater distance apart than the sides of the first pair (S1, S2). The sides of the third pair of sides (S3, S4) are cut so as to be substantially perpendicular to the sides of the first pair of sides (S1, S2).
Abstract:
The invention relates to a device (1) for producing strands (51) from round wood, wherein the strands (51) are 200 to 350 mm long in the direction of the fibers, 0.5 to 3 mm wide perpendicular to the direction of the fibers and 15 to 40 mm thick. The device comprises a rotating chip remover (22) for cutting the strands out of the round wood. Preferably, the chip remover (22) is provided with a plurality of interspaced blades (30), each of which has a substantially radially directed cutting edge (31) for cutting out said strands. The chip remover (22) also has a gap (47) in the cutting edge area, which leads to an intermediate area (49) acting as a chip space. The device has first means (33, 60; 33', 60) assigned to the intermediate area for catching the strands and second means (70, 80) for catching large pieces which fail to enter the intermediate area.
Abstract:
In a method for manufacturing bamboo chips, first the nodes may be removed from the bamboo culms by sawing through the bamboo culms at each side of a node, and then the bamboo culms are peeled preferably by bringing the bamboo culms on rotating rolls provided with knives. After this the bamboo culms are roughly splitted lengthwise preferably by driving a conical bar through the hollow bamboo culm, and thereafter the splitted pieces are finely chipped. In a method for manufacturing bamboo wool, first the bamboo culms are chipped, then the bamboo chips are preferably introduced in a rotating drum (25) containing balls (27) and steam (29) is added to soften the bamboo chips. By pressing the bamboo wool and/or bamboo chips after adding glue and during heating of the mixture, products like boards or profiles (31) can be obtained.
Abstract:
A machine for reducing the size of vegetation to wood chips is provided in which vegetation is introduced to the machine via a roller (13, 18) and conveyor (14) arrangement and is reduced in size to wood chips by a rotating drum (30) is provided with a plurality of pivotable cutting units (80) each having a cutting blade (92) for severing wood chips from the vegetation. The cutting units are pivotally mounted so as to be capable of being retracted or swung away when the cutting units contact a foreign object during operation of the machine so as to prevent or reduce the damage to the cutting unit or machine. After the wood chips are cut from the vegetation they are discharged through a discharge chute (26).
