Underground mining machinery toy

Abstract

A toy or scale replica of an underground toy miner for coal mining having movable parts includes a body having an upper surface and movable caterpillar treads and a plurality of rotatable wheels mounted to the opposed sides of the miner, a boom mounted to the upper surface and extending from the front to the rear of the miner, an endless conveyor mounted on the boom with the distal end of the boom being laterally movable, a bucket mounted to the front and having at least two inwardly rotatably collectors for moving material from the bucket to the conveyor and boom and a ripper head terminating with a cylindrical ripper pivotably mounted to the front of the miner and above the bucket for gouging and digging material out of the wall of the mine for deposition in the bucket and thence movement rearward by the collectors to the conveyor and boom.

1 . A mining machinery toy, comprising:
 a body having a front and a rear, opposed sides, an upper surface and an opposed lower surface;   a pair of tread plates with each tread plate mounted to each opposed side of the body;   a pair of endless caterpillar treads with each caterpillar tread disposed inboard of each respective tread plate;   two sets of wheels with one set of wheels encompassed by one caterpillar tread and the other set of wheels encompassed by the other caterpillar tread whereupon the sets of wheels and the caterpillar treads rotate together;   a boom mounted to the upper surface and extending rearward past the rear of the body;   the boom selectively movable up and down away from and toward the upper surface of the body and the boom including a distal segment that is laterally movable left and right with respect to the body;   an endless conveyor mounted on and extending about the boom;   a bucket mounted to the front of the body;   a pair of collectors mounted inside the bucket with each collector inwardly rotatable toward the other collector;   a ripper head mounted to the front of the body and positioned above the bucket with the ripper head movable up and down away from and toward the bucket; and   a cylindrical ripper rotatably mounted to ripper head with the ripper including a plurality of teeth radially disposed about the ripper.   
   
   
       2 . The mining machinery toy of  claim 1  further comprising a plurality lights that are mounted to each tread plate. 
   
   
       3 . The mining machinery toy of  claim 2  further comprising a pair of headlights mounted to the upper surface of the body and facing toward the front of the body. 
   
   
       4 . The mining machinery toy of  claim 3  further comprising a motor housed within the body and actuated by an on/off switch located on the underside of the body.
