The invention relates to a firewood handling device for firewood pieces (6), comprising a conveyor (1), including one or more rotating, endless chains (9), wherein the conveyor extends from an input end (2) to an output end (4). The conveyor chains are provide with carriers (10), which project outwards from the outer sides of the chains and extend across and on a distance from each other in relation to the longitudinal extension of the conveyor such that spaces are formed between the carriers into which firewood pieces (6) can be positioned having their longitudinal extension across the longitudinal extension of the conveyor. The carriers (10) are formed with at least two, not cut through slots or recesses (42, 43, 44) from below as well as from above which overlap each other, wherein the conveyor (1) in its output end (4) is provided with at least two inner guiding members (45) as well as with at least two outer guiding members (46). Both the inner and the outer guiding members are provided with smooth upper sliding surfaces and are mounted such that the sliding surfaces (45′) of the inner guiding members extend and have an increasing height in the conveying direction and are positioned such that they are aligned with the slots or recesses extending from below in the carriers, whereas the sliding surfaces (46′) of the outer guiding members extend and have a decreasing height in the conveying direction and are positioned such that they are aligned with the slots or recesses extending from above in the carriers, and wherein the sliding surfaces of the inner and the outer guiding members extend essentially without interruption or somewhat overlapping in relation to each other as seen in the conveying direction.

A cleaning pig assembly is provided for use on a tubular drag conveyor. The assembly is quickly and easily mounted anywhere along the cable, chain, or rope via slots in the assembly components. The components include a puck, a plate, a drag disc, and a cleaning member or tool sandwiched between the puck and the plate. The drag disc provides interference fit on the cable, chain, or rope holding the assembly on the cable, chain, or rope and prevents sliding of the assembly along the cable, chain, or rope during use. The cleaning assembly is installed without the use of tools or clamps. Multiple interchangeable cleaning members are provided depending on cleaning needs.

The present invention provides a scraper including a scraper body, having opposed bottom and top surfaces and a supporting body, formed on the bottom surface. The supporting body is provided with a mounting surface forming a part of the bottom surface. The mounting surface is provided with a rolling body able to support the scraping body when the scraper is located at a mounting position. The supporting body is a nonmetallic elastomer. The present invention also provides material conveying equipment using the scraper. By changing a contact and friction mode of the scraper and a conveying groove, a working state of the scraper and a whole load of the conveyor are improved, idle load is reduced, and the whole service life of the scraper and even the scraper conveyor is prolonged.

A conveyor system for translating objects is disclosed, each object with vertical protrusions extending upward and/or downward from one or more sides of the object. The conveyor system can accommodate structural members such as roof truss members, on which connector plates are affixed and from which the connector plates protrude vertically up, down, or both. The conveyor system may have a slide or some other support for the objects. The slide or other support may be narrow. The slide or other support can be tall, relative to an object. The conveyor system may have an engagement tool driven by an overhead carriage to translate the objects along the slide or other support. The engagement tool may be narrow. The engagement tool can be tall, relative to an object.

The present invention provides a material conveying device including a material conveying groove, having a traveling track; a material bearing and conveying assembly, including: an annular chain; traveling units arranged on the chain at intervals, drivable by the chain to move on the traveling track along a material conveying direction, and provided with a bottom surface close to the material conveying groove, a top surface opposite the bottom surface and side surfaces extending between the top and bottom surfaces; a belt-shaped elastic material bearing portion, connected to the top surfaces and/or the side surfaces of the two adjacent traveling units; and a driving device to drive the chain to circularly rotate relative to the material conveying groove along the material conveying direction. The working state of material conveying equipment can be improved, and the stability and economic index of the equipment can be enhanced.
