A supply device with which elements in disordered form, in particular connection elements as bulk elements, are suppliable to a second receiving volume. The supply device includes a first receiving container from which, via an outlet opening, a plurality of elements is deliverable to a second receiving container. The second receiving container may consist of an oscillation feeder. The oscillation energy of the oscillation feeder is specifically transmitted onto the elements, which are stored in the first receiving container. With the help of the transmitted oscillations, elements are transferred from the first receiving container via a transfer zone from the first receiving container into the second receiving container.

A container assembly comprises a container and a base and is configured to be transported horizontally to a work site where it is raised to a vertical working orientation. A hoppered container floor directs material to a discharge opening in a center of the floor of the container. A plurality of chutes is fixed to the container assembly and each slopes downward and outward from a chute input, located under a central portion of the hoppered floor, to a corresponding chute output. A distributor assembly mounted under the discharge opening receives granular material from the discharge opening and directs same into any one of the chute inputs. When loaded on a gooseneck trailer the container extends over the hitch assembly providing increased volume and capacity.

A transport device includes a transport pipe for transporting a material to be transported having at least one of a sheet piece, a fiber, and a powder, and a blower for generating an air flow in the transport pipe, the transport device transports the material to be transported by the air flow, in which the transport pipe has an introduction port into which the material to be transported is introduced, the air flow has a velocity difference in a direction orthogonal to a direction of the air flow in the transport pipe, and the introduction port is provided on a side where a velocity of the air flow is lower.

A collecting chute includes a plurality of chute units having a supply port, a discharge port, and an inner circumferential surface. The chute units are arrayed along a circular virtual line in planar view and are also arrayed securing a space among the chute units at the central portion of the circular virtual line. Each of the chute units has an outer slope that is an inner circumferential surface along the circular virtual line and an inner slope that is the inner circumferential surface located on the back side of an outer circumferential surface facing the other chute units, and the tilt angle of the inner slope is greater than the tilt angle of the outer slope.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. A metering conveyor is positioned between a blender tub and a proppant motive mechanism, such as a conveyor or wash system that receives discharge direct from proppant containers of the type normally used to transport sand in support of a hydraulic fracturing operation. The metering conveyor is fitted with sensors and/or a knife-edge gate that may be used to facilitate flow control operations.

A material application system includes a hopper assembly and a conveyor assembly. The hopper assembly includes an upper portion and a downcomer portion. Bulk material is loaded into the upper portion and passes through the downcomer portion. The downcomer portion may include a sail plate for agitating the bulk material to inhibit the formation of clogs in the bulk material.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is part of an overall system that is used to move sand for use as proppant, and is fitted with a vibration system that facilitates the discharge of sand from the container.

An exemplary embodiment of the present invention is directed to an apparatus for emptying material from a container on a vehicle. The apparatus has a container with a bottom surface and a sidewall. A membrane being mounted within the container proximate the sidewall and the bottom surface. The apparatus further includes an engine and ducts having a first end and a second end. The first end connected to the engine so as to receive gas from the engine and connected at the second end to the membrane so as to direct the gas into the membrane.
