Abstract

Abstract A transfer station which includes an elongated main frame, a conveyor movably mounted in the elongated main frame; a feeder box comprising opposite feed devices connected to opposite sides of the elongated main frame, each feeder device including a box compartment which can be tilted to discharge debris deposited therein onto the moving conveyor; a crusher mechanism for crushing debris carried thereto by the moving conveyor; a discharge chute for discharging the crushed debris into a hauling device; and lifting devices attached to the elongated main frame to lower it onto the ground and place the transfer station in a lowered, operational mode, or raise it above the ground and place the transfer station in an elevated transport mode. Once the transfer station is in its elevated, transport mode a caterpillar tractor can be positioned under the elongated main frame to transport the transfer station to another processing location.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 293 words
A transfer station for processing debris which comprises a unitary, rigid elongated main frame which includes two parallel, rectilinear beam members and defines a front end and a rear end; a conveyor which is movably mounted between said rectilinear beam members of said frame; a crusher mechanism mounted above said elongated main frame for crushing debris deposited on said conveyor; a feeder box positioned at said front end of said elongated main frame, said feeder box including separate feeder devices located on opposite sides of said elongated frame, each feeder device including a box compartment which is pivotally connected to said elongated main frame to be in either a non-tilted or in a tilted orientation, a ground plate below the box compartment which is pivotally connected to said elongated main frame so as to pivot about an axis extending in parallel with said elongated main frame, and a hydraulic cylinder connected between said ground plate and said box compartment thereabove; and a plurality of hydraulic lifting devices for separately raising and lowering each of the front and rear ends of said elongated main frame relative to the ground, each of said pluraity of hydraulic lifting devices comprising a ground-engaging base, a vertical cylinder, and a lifting arm which is fixedly attached to said main frame, said lifting devices functioning to lower said main frame so that both the front and rear ends thereof are in contact with the ground, thereby positioning the transfer station in an operational mode, and to lift both the front and rear ends of said elongated main frame above the ground such that the transfer station is in a transport mode, said transfer station having no elements that extend below said elongated main frame when in said operational mode.
Claim 2
Dependent Claim 293 words
A transfer station for processing debris which comprises a unitary, rigid elongated main frame which includes two parallel, rectilinear beam members and defines a front end and a rear end; a conveyor which is movably mounted between said rectilinear beam members of said frame; a crusher mechanism mounted above said elongated main frame for crushing debris deposited on said conveyor; a feeder box positioned at said front end of said elongated main frame, said feeder box including separate feeder devices located on opposite sides of said elongated frame, each feeder device including a box compartment which is pivotally connected to said elongated main frame to be in either a non-tilted or in a tilted orientation, a ground plate below the box compartment which is pivotally connected to said elongated main frame so as to pivot about an axis extending in parallel with said elongated main frame, and a hydraulic cylinder connected between said ground plate and said box compartment thereabove; and a plurality of hydraulic lifting devices for separately raising and lowering each of the front and rear ends of said elongated main frame relative to the ground, each of said pluraity of hydraulic lifting devices comprising a ground-engaging base, a vertical cylinder, and a lifting arm which is fixedly attached to said main frame, said lifting devices functioning to lower said main frame so that both the front and rear ends thereof are in contact with the ground, thereby positioning the transfer station in an operational mode, and to lift both the front and rear ends of said elongated main frame above the ground such that the transfer station is in a transport mode, said transfer station having no elements that extend below said elongated main frame when in said operational mode.
Claim 3
Dependent Claim 46 words
A transfer station as defined in claim 1, including three of said hydraulic lifting devices, one of which is fixedly attached to said front end of said elongated main frame and two of which are fixedly attached to said rear end of said elongated main frame.
Claim 4
Dependent Claim 74 words
A transfer station as defined in claim 2, including a secondary frame mounted on said main frame, said secondary frame extending upwardly from said elongated main frame at an acute angle and having a free end located beyond said rear end of said elongated main frame, wherein said crusher mechanism is located above said secondary frame, and including a connecting belt moving along said secondary frame to carry crushed material from said crusher mechanism.
Claim 5
Dependent Claim 47 words
A transfer station as defined in claim 1, wherein each box compartment includes a floor, an outer side wall and a plurality of support arms which are pivotally connected to the elongated main frame to pivot about an axis extending in parallel with said elongated main frame.
Claim 6
Dependent Claim 91 words
A transfer station as defined in claim 4, wherein each feeder device includes a plurality of guide blocks which are positioned between its support arms and which are pivotally connected to the elongated main frame, said guide blocks having upper generally flat surfaces to enable debris from the associated box compartment to slide thereover when the associated box compartment is in a tilted orientation, and a curved retainer surface which faces away from the elongated main frame to help retain debris in the associated box compartment when in its non-tilted orientation.
Claim 7
Dependent Claim 58 words
A transfer station as defined in claim 5, wherein the box compartment of each feeder device includes a plurality of curved lock arms which extend below said support arms and which have holes therein to enable pins to be inserted therethrough and into corresponding holes in said guide blocks to lock said box compartments in their tilted orientations.
Claim 8
Dependent Claim 79 words
A transfer station as defined in claim 2, wherein each of said box compartments has open front and rear ends, and including ramps for positioning on the ground adjacent the front and rear ends of each box compartment when in its non-tilted orientation to enable a dump truck to drive up onto the floor of the respective box compartment from either direction, dump its load of debris, and then drive out of the box compartment in the same direction.
