摘要:
An apparatus for performing work on material through vibration. An elongated material receiving surface is provided along with a mount for the same that permits the surface to be vibrated. A vibrating mechanism including two spaced vibratory force generating devices may be adjustably secured to the material receiving surface in any of a variety of positions with respect to the center of gravity of the latter so that the direction of the vibratory force applied to the material receiving surface may be varied.
摘要:
A vibratory conveyor arranged for conveying material in one or more directions and arranged for selective throwing of the material as for cooling the same prior to the conveying operation. The means for vibrating the conveyor is arranged to utilize different portions thereof jointly in different combinations to effect the selective conveying and throwing operations.

A vibratory vertical lift conveyor including a vertically elongated, tubular lift assembly having an inlet at its lower end and an outlet at its upper end. The assembly is provided with generally L-shaped projections extending from end to end within the interior of the assembly to provide for material lifting action when the assembly is vibrating in a vertical direction. Additionally provided is a yieldable connection between the vibrator and the lift assembly to accommodate startup of the conveyor; a mulling sphere within the tubular assembly received therein for limited movement between the projections to mull particulate material passing upward in the assembly; a backflow preventing device at the inlet to preclude backflow of material within the inlet when the vibratory conveyor is moving downwardly; and a manifold and inlet for a treating gas for treating material as it passes upwardly within the assembly.
摘要:
A vibratory conveyor for conveying castings from one point to another while shaking loose adhered sand therefrom. The conveyor includes a grate-like conveying surface formed of metal to support heavy castings of the like as well as to be resistant to the heat of still hot castings. A vibratory mechanism is associated with the metal grate for vibrating the same in such a way as to convey the castings. In order to preclude the steel grate from ''''ringing'''' as it repetitively contacts the castings during operation, an elongated tube is secured to the underside of the grate. The tube is filled with lead shot and serves to dampen the vibration of the grate in the audible range.
摘要:
A vibratory material handling apparatus including a material engaging surface and a vibration imparting device for vibrating the surface. The latter includes a pair of parallel, rotary shafts each mounting an eccentric weight and a prime mover for rotating one of the shafts. The shafts are interconnected so that when the one shaft is rotated, the other will be rotated in the opposite direction and the interconnection is such that there is a substantially positive driving connection between the two shafts which will allow limited slippage so the eccentric weights may synchronize relative to each other and to the center of gravity of the apparatus.

摘要:
A vibratory material handler including a material handling surface, a mechanism for vibrating the same and a housing sealing the vibrating mechanism from particulate material in the surrounding environment. The housing includes an apertured wall through which the motor shaft may extend and which is held in substantial abutment with the motor casing. The remainder of the housing holds a weighted member eccentrically mounted on the shaft and shields the same from particulate material while the substantial abutment of the wall at the motor casing effects a substantial seal between the two to preclude entry of particulate material into the motor itself.
