초록 ▼

A material transfer machine includes a slat conveyor of substantially the width of a feed hopper of a paving machine. The slat conveyor is supported by caster wheels to be disposed at an incline having a material intake end at a lower end thereof and a discharge end at the opposite upper end of the conveyor. The slat conveyor is mounted to a leading edge of the paving machine such that the upper discharge end is disposed above the feed hopper of the paving machine. A hopper is disposed ahead of the lower intake end of the slat conveyor, supported by a frame which is pivotably attached at a rear end thereof along the sides of the slat conveyor to an understructure thereof. The front end of the frame is supported by caster wheels, such that the frame is capable of joint movement with the conveyor and the paving machine while supporting pivotal movement in a vertical plane in response to grande changes of a base grade. Material is transferred from beds of supply trucks by backing the trucks toward the leading edge of the hopper to align the rear of the beds with the hopper. The material is dumped into the hopper and is transferred by the slat conveyor directly from the hopper of the material transfer machine to the feed hopper of the paving machine without getting into contact with the base grade of the road being paved.

대표청구항 ▼

A material transfer machine comprising: means, including a leading lower intake end for paving materials and a trailing upper discharge end for paving materials, for transferring such paving materials receiving at such leading lower intake end in a continuous elevating motion to the trailing upper discharge end and for discharging such paving materials at said upper discharge end; means, including sets of wheels spaced longitudinally of the transferring means, for supporting the transferring means at a predetermined angle with respect to a base grade of a roadway; means, mounted to the transferring means, for coupling the transferring means directionally aligned with, and fixed in a plan view to a front end of a paving machine, wheels in each set of wheels of said means for supporting the transferring means being mounted for supporting movement of the transferring means generally in parallel t the base grade, and directional control transversely of its longitudinal direction and slave to motion of the paver; a support frame extending longitudinally of the transferring means and having a forward and a rear end, the rear end of the support frame pivotally attached to the transferring means intermediate of said longitudinally spaced sets of wheels of the means for supporting the transferring means for pivotal movement of the support frame in a vertical plane longitudinally of the transferring means with respect to the means for supporting the transferring means, said support frame extending from a pivotal attachment at the transferring means longitudinally forward with respect thereto and including means for supporting the forward end of the support frame with respect to the base grade, the means for supporting the forward end of the support frame including a further set of wheels mounted to the forward end of the frame and supporting the frame to move over the base grade; and means, disposed ahead of said transferring means and supported at its forward end by said support frame, for guiding a discharge of paving materials from a bed of a material supply truck positioned ahead of said transferring means into said lower intake end of said transferring means, said guide means including means for transferring forces of the paving materials being discharged from such truck to said support frame and said further set of wheels of the supporting means, whereby the paving materials are transferred from said guide means to said discharge end to be discharged therefrom.
