US 6,312,206 B1 · Method and apparatus for loading bulk materials

Abstract

A method and apparatus for loading bulk materials is disclosed. The apparatus of the present invention comprises a track and a frame movable on the track between a retracted and extended position. A first plate is movably mounted on the frame, and a ram is operably connected to the first plate for moving it between a retracted and extended position. A feeder may also secured to the frame. In operating a press such as the one disclosed, the frame and plate are moved within the container, a compressible material is transferred into the container, the compressible material is compressed, and the frame and plate are moved to a position outside the container. The steps of transferring compressible material into the container and compressing it may be repeated as desired. The frame may also be equipped with a second plate in which case one plate may be compressing material while additional compressible material is simultaneously being transferred into another portion of the container. The container may be a rail car, and the compressible material may be selected from the group consisting of cottonseed, cottonseed hulls, rice hulls, rice mill feed, and soy bean hulls.

(g) returning said second plate from said extended position to said retracted position;
and
(h) moving said press from said second position to said first position after compressing said first and second amounts of said compressible material;
(i) aligning a second container with said press;
(j) moving said press from said first position to a third position in which at least a portion of said press is inside said second container;
(k) transferring a third amount of compressible material into a first portion of said second container;
(l) moving said first plate from said retracted position to said extended position to compress said third amount of said compressible material;
(m) returning said first plate from said extended position to said retracted position;
(n) transferring a fourth amount of said compressible material into a second portion of said second container;
(o) moving said second plate from said retracted position to said extended position to compress said fourth amount of said compressible material;
(p) returning said second plate from said extended position to said retracted position;
and
(q) moving said press from said third position to a fourth position outside of said second container after compressing said third and fourth amounts of said compressible material.
