Abstract
A tiltable hopper is supported on force transducers and has a chute which closes one end of the hopper in the raised position and bridges a space between the hopper and a material receiving bucket. Weight computing, recording and displaying means are coupled to the force transducers.
Claims5
In combination:
- A tiltable hopper supported on a plurality of force transducers for measuring the weight of the hopper and any material charged thereto;
- a chute designed to close the end of the tiltable hopper in the raised position and to bridge the horizontal space between the hopper and a material receiving bucket laterally disposed thereto in the lowered position;
- means of supporting the outboard end of the chute and simultaneously restraining the receiving bucket from movement;
- electromotive means of raising and lowering the chute;
- electromotive means of tilting the hopper;
- weight computing, recording and displaying means coupled to the force transducers;
- means of simultaneously causing the weight of the material in the hopper and coded data corresponding to the type of material to be registered in the weight computer memory, the chute to lower, the hopper to tilt and to return the hopper and chute to their load positions when emptied;
- wireless control means of initiating the functions of weight and coded data registration and empty and return functions from a remote location;
- means of transmitting the material weight and coded data to a remote data processing terminal;
- means of readily moving the weighing apparatus to a multiplicity of operating locations.
