The present invention consists of a powered wood chipper mounted directly or indirectly to the frame of a utility type truck, thus eliminating the need for a separate trailer to carry said wood chipper to job sites. Said invention may also include a dump box, mounted directly or indirectly to the frame of the utility type truck, and whereby said dump box may be a sideways tilting assembly or may have a fixed position and incorporate a slanted or tilting floor assembly. Said dump box may also include a unique horizontal dump door arrangement with both an upper and lower doors. Presence of said lower dump door allows the dump box to discharge its load at a distance from the utility type vehicle. Said dump box may also feature slanted side or top surfaces, which may allow for greater visibility from the cab of the utility type vehicle and/or greater aerodynamics. These slanted side or top surfaces also allow the overall vehicle to have a narrower or lower profile and a lower center of gravity, leading to improved handling and safety for the work crew.

A device and method for cutting lumber pieces into shavings. The device includes a hopper sized to hold the lumber pieces that are to be cut into the shavings, and a carriage that is positioned below the hopper. The carriage includes a support platform to support the lumber pieces that are in the hopper, and cutterheads spaced apart along the support platform. The carriage is movable relative to the hopper to move the cutterheads back and forth along the lumber pieces during the cutting. An arrestor maintains the lumber pieces in position relative to the hopper when the carriage is moving in one direction to prevent and/or reduce the lumber pieces from moving and thus not being completely cut by the carriage.

The present disclosure relates to the technical field of resource recycling and provides a processing method for a waste oriented strand board and waste oriented wood chips, and an oriented strand board preparation method thereof. The processing method for a waste oriented strand board provided in the present disclosure includes the following steps: softening a waste oriented strand board to obtain a softened waste oriented strand board; and flaking the softened waste oriented strand board pieces using a disc flaker to obtain waste oriented wood chips. According to the present disclosure, the waste oriented strand board is softened first to be chipped readily. It is specified in the present disclosure that the disc flaker is used such that relatively intact wood chips can be obtained.

An apparatus, system and method for adjusting and setting a fixed position of an axially displaceable shaft and rotary chipper disc combination, without requiring an attachment to or obstruction of an end face of either end of the axially displaceable shaft. A rotary chipper disc recoil mechanism is also provided for the purpose of detection of unwanted axial forces placed upon the rotating shaft caused by unintentional chipping of metal, and for limiting consequential damage caused by the unintentional chipping of metal and other non-wood materials.

A plunger assembly for mounting adjacent to a vertical opening of a debarking chain flail apparatus. The plunger assembly comprises first and second opposed mounting members which are securable to an undersurface thereof, and each one of mounting members defines a generally C-shaped recess. First and second plunger rails are interconnected via a plunger body, and the plunger body comprising opposed left side and right side plunging side surfaces. The first plunger rail is captively received within and guided by the first mounting frame while the second plunger rail is captively received within and guided by the second mounting frame. A first hydraulic cylinder interconnects the first mounting frame with the first plunger rail while a second hydraulic cylinder interconnects the second mounting frame with the second plunger rail to facilitate plunging in two opposed directions. The mounting frame may be mounted to the apparatus by a pair of plunger cradle and associated cradle hydraulic cylinders.

A waste processing machine for reducing material and having a feed assist system. A cutting assembly on a frame reduces material. A feed system on the frame directs material toward the cutting assembly. A winch assembly includes a line with a line end for securing material, and a driver on the frame to urge the line end toward the driver. A keeper fixed to the frame secures the line end. A sensor detects utilization between: a docked configuration with the line tensioned against between the driver and the keeper; and an undocked configuration with the line loosened. A control unit allows operation of the feed system in the docked configuration, and interrupts the feed system in the undocked configuration. A feed mechanism actuation bypasses the interrupted operation to advance material for a bypass period, and a limit mechanism overrides operation of the feed mechanism for a subsequent limit period.
