An agricultural grain storage or feed tank including a body with a roof having an upper inlet opening is provided with a roof cap assembly which includes an elongated and vertically extending control rod which is vertically and pivotably movable with respect to the body of the tank whereby a cap connected to the control rod may be selectively moved remotely from the opening by raising the control rod and thereafter swinging the cap relative to the opening. The opening is reinforced by a reinforcing centering ring which is selectively mounted to the exterior of the roof of the tank and which includes a plurality of support rods on which the cap is normally seated so as to create an air passageway into the inlet opening. In the preferred embodiment, the body of the tank is corrugated and is supported by legs having corrugated sections which interfit with the body of the tank.
A roof cap assembly for use with an agricultural storage and feed tank wherein the tank includes a body having upper and lower portions and wherein the upper portion includes an inlet opening, the roof cap assembly comprising, a roof cap of a size to cover an the inlet opening when in a first position, a control rod having a vertically extending portion and a cantilevered portion, said cantilevered portion being connected to said roof cap, a handle assembly mounted to said vertical portion of said control rod and extending outwardly therefrom, and mounting means for mounting said control rod to a tank so that said cantilevered portion of said control rod and said roof cap are vertically moveable and horizontally swingable with respect to the inlet opening, whereby said handle assembly is engageable to raise said control rod to lift said roof cap relative to the inlet opening and thereafter is manipulable to rotate said control rod to swing said roof cap horizontally laterally relative to the inlet opening to a second position horizontally spaced from said first position to permit access to the inlet opening.
An agricultural storage and feed tank comprising, a body having upper and lower portions and wherein said upper portion includes a roof having an inlet opening, a roof cap assembly including a roof cap of a size to cover said inlet opening when in a first position relative thereto and a control rod having a vertically extending portion and a cantilevered portion, said cantilevered portion being connected to said roof cap, a handle mounted to said vertical portion of said control rod and extending outwardly therefrom, mounting means for mounting said control rod to said body of the tank so as said control rod and cap are vertically moveable and horizontally rotatable with respect to the inlet opening so that said handle assembly is engageable to raise said control rod to lift said roof cad relative to said inlet opening and thereafter manipulated to rotate said control rod to swing said roof cap laterally relative to said inlet opening to a second position to permit access to said inlet opening, said mounting means for mounting including a guide means mounted to said body of the tank, said vertical portion of said control rod extending through said guide means, a guide plate connected to the tank, said guide plate defining at least one vertical slot in which said handle assembly is slidingly received when said roof cap is in said second position, said guide plate defining a second vertical slot in which said handle assembly is slidably disposed when said roof cap is in said first position, a plurality of support rods mounted to said roof and extending radially outwardly relative to said inlet opening therein, each of said support rods having a portion which is spaced from said roof, and means for mounting said support rods to said roof whereby when said roof cap is seated on said support rods, said roof cap is in spaced relationship with respect to said roof and a ventilation air space is created therebetween.
An agricultural grain tank comprising a body having upper and lower ends, a roof mounted to said upper end of said body, a discharge chute mounted to said lower portion of said body, an inlet opening to said body in said roof, a roof cap assembly including a cap of a size to cover said inlet opening into said body and a control rod, said control rod having a cantilevered portion connected to said cap and a vertical portion, means for guidingly mounting and controlling said vertical portion of said control rod to said body of the tank so that said control rod is vertically raised and horizontally rotated relative to said body to thereby raise said cap and horizontally swing said cap away from a first position covering said inlet opening to a second position entirely spaced from said inlet opening.
A roof cap assembly for use with an agricultural storage and feed tank wherein the tank includes a body having upper and lower portions and wherein the upper portion includes an inlet opening, the roof cap assembly comprising, a roof cap of a size to cover the inlet opening when in a first position relative thereto, a control rod having a vertically extending portion and a cantilevered portion, said cantilevered portion being connected to said roof cap, control means for vertically raising and rotating said control rod, mounting said control rod to the tank so that said cantilevered portion and said roof cap are vertically and horizontally moveable with respect to the inlet opening whereby said roof cap is raised relative to the inlet opening and thereafter swung laterally relative to the inlet opening to a position to permit access to the inlet opening.
