Description

MATERIAL HANDLING APPARATUS
This invention relates to a material handling apparatus for use, for example, in back-filling drainage trenches with discrete material with such as stone chippings, pea gravel, sand or the like, replacing clean sand in golf bunkers, top-dressing/spreading sand, lime or other aggregates on the ground, such as sports grounds, filling areas, such as flower beds, with sand, wood bark, mulch or other materials or for use with other material handling apparatus. Accordingly, the present invention is a material handling apparatus comprising a chassis having ground-engaging wheels, the chassis fixedly mounting one part a two part rotatable mechanism, the other part of which being made fast to a pair of spaced elongate members between which a conveyor assembly is provided, a conveyor of which is capable of lengthwise extension, a hopper being securely mounted above the conveyor with its outlet feeding onto the conveyor, the conveyor assembly being capable of rotation relative to the chassis. Preferably, the rotatable mechanism is a turntable or a slewing ring. Preferably also, rotation means comprises one or more first hydraulic ram and cylinder arrangements fixed between the other part of the mechanism and the chassis to effect rotation of the members and the assembly. Preferably also, the assembly is capable of being inclined upwardly relative to the elongate members. A means for inclination desirably comprises one or more second hydraulic ram and cylinder arrangements fixed between the elongate members and the assembly. Preferably further, the conveyor has opposed side members stayed together and at and between opposite ends of which rollers are cross-mounted with an endless belt arranged therearound. The assembly preferably includes the conveyor whose side members each have two or more castors tracking a channel in a respective channel member, the channei members being inwardiy facing and each iying adjacent to a respective elongate member. The channel members are desirably pivoted, each to its respective elongate member at the towing end of the chassis. The conveyor is desirably lengthwise slidable relative to the channel members. The hopper is beneficially secured to the top of the channel members. Means to extend the conveyor outwardly in a length-wise direction, either forwardly or rearwardly, relative to the direction of travel, beneficially comprises one or more third hydraulic and ram cylinder arrangements secured between the or each side member and the respective channel member. An embodiment of the present invention will now be described, by way of example. A material handling apparatus comprises an elongate chassis having a set of four ground-engaging wheels carried on an axle at one end, i.e. trailing end, with a tow bar at the opposite or towing end. The tow bar is off-set downwardly whereby when the apparatus is in the form of a trailer, and de-coupled from a tractor unit, the front of the tow bar is ground- engaging and the chassis is substantially horizontal. A two-part ' annular rotatable mechanism is provided with one outer part being fixedly mounted on the chassis, the other or inner part being made fast with a pair of spaced elongate members between which a conveyor assembly is provided. In this embodiment, the rotatable mechanism is an annular turntable. A conveyor of the conveyor assembly is positioned and capable of lengthwise extension. The conveyor has opposed side members stayed together and at opposite ends of which rollers are cross-mounted and arranged around which an endless belt is carried. The upper flight of the belt is concaved by being run across a spaced series of roller assemblies, each comprising three low friction rotatable rollers, a central horizontal roller with the other two rollers flanking and diverging upwardly therefrom. The conveyor assembly includes the conveyor whose side members each have two or more castors tracking a channel in a respective channel member. The channel members are inwardly facing and each lie adjacent to a respective elongate member. The channel members are pivoted, each to its respective elongate member at the towing end of the chassis. A hopper is supported on a frame which is securely mounted to the channel members above the conveyor with its outlet feeding onto the conveyor. The hopper has a gate operated hydraulically to close off the outlet. The conveyor assembly and hopper form a unit capable of rotation through a substantially 180° arc relative to the chassis. Rotation means comprises two first hydraulic ram and cylinder arrangements fixed between the inner part of the turntable and the chassis to effect rotation of the members and the conveyor assembly, the arrangements being coupled hydraulically whereby they act oppositely, i.e. when one extends, the other retracts to cause the rotation. The assembly is capable of being inclined upwardly relative to and at the rear of the chassis. Means for inclination comprises two second hydraulic ram and cylinder arrangements, one on each lateral side, fixed between the elongate members and hopper. The conveyor is lengthwise slidable in the channel members. Means to extend the conveyor outwardly in a rearward direction relative to the direction of travel or in the opposite direction comprises two third hydraulic and ram cylinder arrangements, one on each lateral side, secured between the channel member and a lug upstanding from respective side members. At the rear discharge end, a first attachment comprising a spinning rotor or two spinning discs are provided for broadcasting the material being conveyed. One or two chutes are provided above the rotor or discs to feed material discharged from the conveyor onto the rotor or discs. The attachment is attached to the chassis. The spinning discs may have equi-spaced upstanding radial baffles. Alternatively, a second attachment is provided comprising a paddle type rotor mounted on the side members to the discharge end of the conveyor. Ail the arrangements and hydraulically operated components are connected to a supply of hydraulic fluid and a hydraulic pump. Separate controls may be operated electrically from the cab of a traction unit or may be manually operable from a control panel mounted at the tow-bar end of the chassis. Means to lock the conveyor assembly to one or both elongate members is provided, (particularly for travelling), the means comprising both the elongate member and respective side of the chassis being provided with a collar welded thereto, the collar being vertically aligned when the elongate member is inboard, and a headed pin is located therein. In use, after the chassis has been towed to the required location, material to be handled for distributing or broadcasting is fed into the hopper and the conveyor is length-adjusted so that the discharge from the end of the conveyor is positioned where required either as a full load deposit or the commencement of a line of deposit as the chassis is towed along parallel to the line where the deposit is required. In a second embodiment, the rotatable mechanism is a slewing ring whose second part has a toothed outer surface which meshes with a planetary gear wheel, rotation of the gear wheel, through gear chain if necessary, by one first hydraulic ran and cylinder arrangement causing the second part to rotate. The first hydraulic ram and cylinder arrangement can be replaced by a hydraulic motor acting axially of the gear wheel. In a modification, the chassis may have two sets of wheels, one at each end of the chassis. The chassis may be self-propelled. Variations and modifications can be made without departing from the scope of the invention described above as claimed hereinafter.
