Abstract:
A chain for a conveyor comprising an elongated base means (8, 9) having a bottom and upstanding side guides or flanges (11, 12) is provided. The chain is a continuous chain adapted to be driven so that one of its spans moves longitudinally along the upper surface of the base means bottom (10) and between side guides or flanges in a conveying direction so as to advance the material being conveyed. The chain comprises a plurality of Y-shaped connector links (20) and a plurality of flight arms connecting links (34) having arms attached thereto and normally extending substantially transversely of the conveying direction. Adjacent elements (41) are joined together by a series of bearing and retaining pins (30, 31) so as to permit vertical and horizontal articulation. The flight arms are attached to the flight arm connecting links (34) independently of the main bearing pins (30) that hold the various links of the chain together.
Abstract:
A trailer unloading system anchors one or more trailers to a deck, with, or without tractor attached. The sides of the trailers are free to pivot from a top, longitudinal, pivot axis once unlatched from the edge of the trailer floor. The deck tilts the trailers sideways, the doors swing free, and the load discharges. The deck returns to level, the sides latch to support the floor and the trailers are ready to be reloaded.
Abstract:
An apparatus for supplying raw materials at constant amounts has a raw material tank for storing and feeding raw materials, a belt for transferring raw materials, a level control guide for defining a thickness of raw materials on the belt, and a belt cover. The apparatus further includes a reversible belt drive motor for controlling a rotation direction of the belt forward and backward and a device for removing raw materials arranged at a backward side of the belt. In the case of supplying the raw materials at constant amounts, a normal operation of supplying the raw materials is performed by rotating the belt in a forward direction. In the case of removing the raw materials arranged on the belt and in the raw material tank, the raw materials are transferred to the device for removing raw materials arranged at a backward side of the belt by rotating the belt in a backward direction so as to remove the raw materials from the belt and the raw material tank.
Abstract:
A particulate material conveying apparatus generally consisting of an upper conduit having a material receiving inlet; a first intermediate conduit communicating with the upper conduit and swivable relative to the upper conduit about a first axis; a second intermediate conduit communicating with the first intermediate conduit and swivelable relative to the first intermediate conduit about a second axis parallel to the first axis; a lower conduit having a material discharge outlet, communicating with the second intermediate conduit and swivable relative to the second intermediate conduit about a third axis parallel to the second axis; and a mechanism for translating the angular displacement of the second intermediate conduit relative to the first intermediate conduit about the second axis to angular displacement of the first intermediate conduit relative to the upper conduit about the first axis.
Abstract:
A wear strip easily mountable on an outer surface of a support member or structure of a feeder of an agricultural combine, for preventing wear of the support member and a feeder chain movable thereover. The wear strip includes an elongate body of a molded plastics material having a longitudinal extending side to be positioned in facing relation to the chain and an opposite longitudinally extending mounting side to be mounted on the support member, the mounting side including at least one molded plastics mounting tab extending outwardly therefrom in a position for insertion into at least one hole through the support member, respectively. The mounting tab includes at least one resiliently displaceable or biasable projection spaced from the body and oriented so as to extend in a predetermined direction from the mounting tab, the projection defining a locking portion or detent for cooperatively engaging an edge of the hole or an inner surface of the support member for holding the tab in the hole with the mounting surface of the body in abutting relation to the outer surface of the support member while allowing limited longitudinal movement of the body relative to the support member.
Abstract:
The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. In chain scraper conveyors with a large distance between the main and auxiliary drive stations, e.g. a distance of more than 400 m, a chain breakage in the bottom run or a shaft breakage can arise, which can be traced back to vibration phenomena in the chain. The invention proposes to filter out a detection signal (Serk), representative of the currently arising vibrations of the chain (1), from the operating data of the main and auxiliary drives (I, II) by means of a detection device (34), and to take this to an active suppressor (35), which generates a time-variable control signal (STilgung) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.g (Ssoll) for the closing pressure adjustment of a multiple disc clutch (6) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain (1).
Abstract:
A fluid plenum trough conveyor support that provides a near frictionless fluid film bearing to support a conveyor belt. The apparatus of the present invention may be used as a discrete conveyor belt support element. The discrete elements formed by the method of the present invention may also be sealingly joined to form a continuous trough conveyor path for a conveyor system. An improved particulate collection system is provided at termination points of the conveyor system for eliminating particulate emissions as the bulk materials transported by the conveyor are unloaded or transferred to receiving points.
Abstract:
A dual belt conveyor includes a pair of flexible endless loop conveyor belts arranged at an incline with a lower flight of the upper belt in face-to-face conveying relationship with an upper flight of the lower belt to retain and convey granular material between the belts. Drive pulleys are connected to both belts to move the belts at the same speed, and the conveying flights of the belts are journaled through a trough which forces the belts into a curved concave orientation between the side edges with the upper belt biased downwardly into engagement with product on the lower belt to retain product therebetween.
Abstract:
A conveyor system for increasing the angle capabilities and allowing shorter lengths of a belt conveyor. The device includes a support frame, a tube attached to the support frame, a receiver support structure attached to the intake end of the tube, an endless belt positioned within the tube and about the receiver support structure, a plurality of paddle members attached to the outer surface of the endless belt, and a wind skirt attached to the lower portion of the tube. The plurality of paddle members include a plurality of V-shaped cutouts with a rounded narrow portion for allowing the endless belt to have a curved state or flat state. A foam member is positioned within the discharge end of the tube having guide slots for receiving the endless belt. The endless belt has a generally flat structure when positioned upon the receiver support structure and transitions to a curved structure when entering the tube.
Abstract:
The invention relates to a continuous cable conveyor for steep and substantially vertical up-and-down transport, preferably of bulk materials up to extreme transport height which can reach approximately 1,000 m. The transport line is made of extremely resistant fiber cables used as traction means. Guide cables and individual carrier means in the form of buckets are fixed at a distance from each other, over said traction means, at cable clamping connections and endless cable connections designed in a specific manner allowing not only convex returns of the transport line but also concave returns in order to create horizontal or inclined reception and distribution areas. Said transport line is driven, returned, tensioned and guided in a non-positive manner by means of cable pulleys with a possible torsion about the longitudinal axis which can react 180°.
