Abstract
An expandable and collapsible grain bin is provided, comprising: two telescoping cylindrical sections, an upper bin section and a lower bin section, the two telescoping cylindrical sections adapted to automatically interlock with one another when the grain bin is in an expanded position; a first lifting system for lifting the upper bin section until the upper bin section automatically interlocks with the lower bin section and lowering the upper bin section when collapsing the grain bin for storage or transport; and a bin cover attached at or near the top of the upper bin section for enclosing the grain bin.
Claims13
An expandable and collapsible grain bin, comprising:
- two telescoping cylindrical sections, an upper bin section and a lower bin section, the two telescoping cylindrical sections adapted to automatically and reversibly interlock with one another when the grain bin is in an expanded position;
- a first lifting system for lifting the upper bin section until the upper bin section automatically interlocks with the lower bin section and for automatically unlocking and lowering the upper bin section when collapsing the grain bin for storage or transport;
- a plurality of support legs secured to the lower bin section for securing the grain bin to a base, wherein the first lifting system is attached to at least one of the plurality of support legs;
- and
- a bin cover attached at or near the top of the upper bin section for enclosing the grain bin.
An expandable and collapsible grain bin, comprising:
- two telescoping cylindrical sections, an upper bin section and a lower bin section, the two telescoping cylindrical sections adapted to automatically and reversibly interlock with one another when the grain bin is in an expanded position;
- a first lifting system for lifting the upper bin section until the upper bin section automatically interlocks with the lower bin section and for automatically unlocking and lowering the upper bin section when collapsing the grain bin for storage or transport, wherein the first lifting system comprises a continuous loop lifting chain vertically extending and coupled adjacent an outer surface of the lower bin section, the continuous loop lifting chain wrapped around an upper sprocket and a lower sprocket, a lifting hook secured to move with the lifting chain and positioned near the bottom of the continuous loop lifting chain, when the grain bin is in a collapsed position, such that a lower edge of the upper bin section engages with the lifting hook, and a reversible hydraulic or electric motor to rotate the continuous loop lifting chain to raise and lower the upper bin section;
- and
- a bin cover attached at or near the top of the upper bin section for enclosing the grain bin.
