An apparatus includes a first transverse conveyor, first and second pairs of foldable parallel ramps, and first and second foldable longitudinal conveyors. The transverse conveyor moves material in a first direction. The first pair of foldable parallel ramps extend from a first side of the transverse conveyor. The first foldable longitudinal conveyor is positioned between the ramps of the first pair, and is configured to move material toward the transverse conveyor in a second orthogonal direction. The second pair of foldable parallel ramps extend from a second side of the transverse conveyor and are in alignment with the ramps of the first pair. The second foldable longitudinal conveyor is positioned between the ramps of the second pair and is configured to move material in a third direction that is substantially opposite the second direction.

A material transfer vehicle includes a material receiving device that is adapted to receive asphalt paving material, and a receiving conveyor that is operatively attached to the material receiving device. The receiving conveyor is driven by a chain drive assembly and includes a chain tension adjustment assembly. The receiving conveyor is pivotable about a substantially horizontal axis so that it can be moved between a transport configuration in which the material receiving device is raised, an intermediate adjustment configuration, and a working configuration in which the material receiving device is lowered. A housing structure encloses protected components and includes an opening adjacent to the protected components. A combination door and platform is attached to the housing structure and is adapted to be moved between a closed configuration that covers the opening and an open configuration that provides access to the protected components, and also provides a platform on which an operator can stand to access the chain tension adjustment assembly.

An apparatus for washing and grading sand and aggregate includes a first multi-deck screen and a sump for collecting undersize material from the plurality of decks. A first set of hydrocyclones receives undersize material and water from the sump of the first screen. A second screen has a deck for producing at least one sand product and a sump beneath the deck, the deck of the second screen receiving an underflow from each cyclone of the first set of hydrocyclones. A second set of hydrocyclones receives undersize material and water from the sump of the second vibratory screen. The deck of a third screen receives an underflow from each cyclone of the second set of hydrocyclones. A further hydrocyclone receives undersize material and water from the sump of the third screen, and an underflow from the further hydrocyclone is delivered onto the deck of the third screen.

To provide a highly reliable combination weighing device having an object supply chute disposed above a dispersion section, which can prevent foreign matter from being mixed into objects due to the falling of screw members from a support frame supporting the object supply chute. A combination weighing device is provided with a dispersion section, weighing hoppers, a control unit, an object supply chute (150), and a support frame (100). The dispersion section disperses and supplies objects around the dispersion section. The weighing hoppers are arranged around the dispersion section. The control unit performs combination calculation based on weighing values in the weighing hoppers. The object supply chute is placed above the dispersion section and supplies the objects to the dispersion section. The support frame supports the object supply chute. The support frame includes members (111, 113, and 114) as engaged members, hooks as engaging members that engage with the engaged members, and fixing members (140) as non-screw members. The fixing members press the engaging members against the engaged members and fix the engaging members to the engaged members.

A depositing device for depositing poultry from a pile of one or more stacked crates to a poultry conveyor. A tilting unit is configured for tilting the pile of one or more stacked crates around a tilt axis between a receiving position and a depositing position. A chute is tiltable between the receiving position and the depositing position independently to the tilting unit.
