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 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.

The present invention pertains a replacement liner (10) for insertion in a conveyor pan (100) of a chain type conveyor (200), comprising a floor part (12) having a left connection surface (14) and a right connection surface (16), a left side part (18) having a left side part connection surface (20) connectable to the left connection surface (14), and a right side part (22) having a right side part connection surface (24) connectable to the right connection surface (16). The connection surfaces (14, 20, 16, 24) are configured to form, in a connected state, a form-fitted connection with their complementary connection surface (14, 20; 16, 24). The present invention further pertains to a conveyor pan (100), a chain type conveyor (200) comprising such, a liner replacement method and a liner sheet.
