A hopper lid for a hopper having a top opening may include a top panel, side channels formed on sides of the hopper lid and configured to engage side ridges of the hopper for the hopper lid to slide over the top opening, a front stop formed on a front of the hopper lid and configured to engage a front ridge of the hopper to stop the hopper lid from further sliding rearward when the top panel fully covers the top opening, and an undulation formed on the hopper lid protruding vertically lower than the top panel and adjacent the front stop to, together with the front stop form a detent that, when the top panel fully covers the top opening, traps the front ridge of the hopper between the front stop and the undulation to resist slide of the hopper lid, effectively locking the hopper lid to the hopper.

Embodiments of the disclosure provide a liner structure adapted for insertion within a discharge spout of a container. The liner structure may include a neck formed of a liner material and enclosing a cross-sectional area substantially equal to a cross-sectional area of the discharge spout. A collar formed of the liner material may be coupled circumferentially to an end of the neck, wherein the collar has a cross-sectional area greater than the cross-sectional area of the discharge spout. A constrictable sidewall is on the neck proximate the collar. Constricting the constrictable sidewall compresses the collar such that it is within the cross-sectional area.

A system for dispensing toppings onto a topping vehicle may include a hopper platform, hoppers, a retaining plate, a blade, and a hopper-advancing pin. The hoppers each include a hopper bracket slidably engaging the hopper platform. The blade is mounted on the retaining plate and may reciprocate relative to the retaining plate. The hopper-advancing pin is movable relative to the hoppers between deployed and stowed positions. The hopper-advancing pin may engage one of the hopper brackets in the deployed position such that movement of the retaining plate between retracted and extended positions causes movement of the hopper bracket and a respective hopper along a length of the hopper platform. The hopper-advancing pin may be disengaged from the hopper brackets in the stowed position to allow movement of the retaining plate between the retracted and extended positions without causing movement of the hopper brackets.

A bulk material transport system includes one or more bulk material transport bins, weighing platforms, and vehicles arranged in various combinations as bulk material transporters, assemblies, and units. The system is useful for coupling with a bulk material container, forming a reduced pressure region at an inlet of the transport bin, and dispensing bulk material into the transport bin through the reduced pressure region.

A bulk material discharging system includes a transmission station including a transmitting vessel having a transmitting vessel inlet configured to receive bulk material from an outlet of a bulk material transporter, and a transmitting vessel outlet to transmit bulk material therefrom. The system also includes a transporter handling station located operatively upstream of the transmission station and including at least a portion of a transporter handler including at least one carriage with transporter couplings configured to engage corresponding carriage couplings of the bulk material transporter and configured to convey the bulk material transporter over the transmitting vessel.
