摘要:
A system for profiling particulate material in an open top conveyance comprises a profiling structure supported above the open top conveyance and engaging the particulate matter in the open top conveyance as the open top conveyance moves in a forward direction therebelow so that the particulate matter forward of the profiling structure is given a generally uniform profile in at least a longitudinal middle portion of the open top conveyance. The open top conveyance normally is one of a sequential train of gondola cars moving on a pair of rails extending under the profiling structure, and the particulate material typically is or comprises coal.

A device for supplying a mixture of pieces of material or fragments of different materials and sizes to one or more receiving units wherein the mixture is supplied to the device within a relatively limited area from where it is distributed to the receiving units so that each of them receives a substantially uniform layer of the mixture at the same time as it is spread out over a wide area. The device comprises one or more vibrating troughs each with a supporting surface at the receiving end and a protuberance centrally mounted in the trough from which the material is spread over the supporting surface (15) during the formation of a uniformly thick layer of material which is carried along the supporting surface to the discharge end of each vibrating trough where it is discharged.

A macaroni distributor shaker is disclosed in which short cut macaroni, noodles or other alimentary paste particles in partially dried form are received within a hopper of partial cone shape at the top of the shaker and thereafter advanced along the length of an elongated chute extending from one side of the hopper to a lower open end of the chute for distribution over a moving drying screen therebelow. The macaroni particles are uniformly and evenly distributed on the drying screen by vibratory motion of the chute in the direction of elongation thereof combined with reciprocating rotational movement of the chute and included hopper about a generally vertical axis at a slower rate such that the lower open end of the chute reciprocates laterally between the opposite edges of the drying screen. The vibratory and lateral motions are generated from a single drive motor coupled to drive a rotatable shaft including an eccentric bearing and a gear reduction mechanism. The vibratory motion results from a connecting rod coupled between the eccentric bearing and the chute which is mounted to a base frame for longitudinal movement relative thereto by a plurality of elongated elements pivotably mounted to the base frame and to the chute. Reciprocating rotational motion of the chute is provided by a rotary cranking mechanism which is rotatably mounted on the base frame and coupled to a rotating arm on the gear reduction mechanism and to a support frame on which the base frame is pivotably mounted for rotation about a generally vertical axis.

An apparatus for delivering a stream of green pellets has a wide belt conveyor and a vibrating conveyor having a deck for supporting the green pellets and conveying the green pellets to the wide belt conveyor in a direction of conveyance over a discharge edge. The discharge edge has an adjustable configuration and extends at an acute angle to the conveyance direction across the conveyance surface of the wide belt conveyor whereby the green pellets discharged over the edge form a layer on the conveyance surface. A plurality of parallel deck bars are axially slidably connected to the vibrating conveyor deck and have end portions protruding therefrom in the conveyance direction, the protruding deck bar ends defining the discharge edge. The deck bars are connected to drives for axially sliding the deck bars for adjusting the discharge edge configuration.

The proppants processing system comprises one or more in-feed conveyors, one or more out-feed conveyors, one or more primary feed bin assemblies, one or more secondary bin assemblies, the primary and secondary bin assemblies each comprising one or more bins and one or more bin conveyors. The proppants processing system further comprises a final transport conveyor and a control unit adapted to control flow of the proppants. A method of processing proppants, the method comprising the steps of providing proppants comprising dry or wet sand; using an in-feed conveyor, transferring the proppants from a transport vehicle to one or more bins of a primary feed bin assembly; moving the proppants from the one or more bins to a feed bin conveyor; moving the proppants from the feed bin conveyor to a final transport conveyor; and using the final transport conveyor, moving the proppants to a blender.
摘要:
The invention relates to a machine for handling waste material, the machine comprising an upper conveyor member with a conveying portion of a first width, a downstream lower conveyor member with a receiving portion of equal or greater width and an apparatus for distributing material from the upper conveyor member to the downstream lower conveyor member, wherein the apparatus comprises oscillating means, a drive mechanism connected to the oscillating means; and a protruding element attached to the oscillating means for oscillatory movement thereof, wherein the protruding element is a reciprocating attachment adapted to oscillate in a direction transverse to the direction in which it extends, wherein the apparatus is mountable between the conveying portion of the upper conveyor member and the receiving portion of the downstream lower conveyor member such that the protruding element extends substantially in the direction of conveyance of the downstream conveyor member; and wherein in use the oscillating protruding element agitates material being transferred from the upper conveyor member to the downstream lower conveyor member.

Devices, systems, and methods for autonomously packing unfolded laundry articles into a box are described. The system includes a box configured to receive the laundry articles, a movable surface for receiving the box, and at least one actuator for imparting at least one of a shaking, twisting, vibrating, oscillating, shushling, and tilting motion to the box. A plunger is configured to compress the articles within the box and at least one sensor is configured to detect that the mass of articles is flattened and substantially level across a top surface. A controller in communication with drive motors, actuators, and at least one sensor is configured to determine whether the articles are flattened sufficiently for delivery to a packing station for receipt of folded laundry articles placed atop the plurality of unfolded laundry articles.
