Abstract

A door for a grain bin having a container associated therewith which is adapted to be connected to a grain bin and extended into the grain storing portion of the grain bin. An opening is disposed in a lower portion of a rear wall of the container and a front wall of the container leading to the outside of the grain bin is removable and is optionally transparent. A grain port in the top rear wall of the container has a sliding gate associated therewith for opening or closing the grain port or metering grain through the grain port. An extension spout is formed on the front bottom of the container for selectively extending the bottom portion of the container, thereby facilitating a selectively controlled flow of grain out of the grain bin.

Claims

1. A grain viewing and sampling device in combination with a grain bin having sidewalls, comprising:

a container having a rear wall and a front wall, and laterally extending walls, extending from the rear wall to the front wall, said rear wall having an opening in a lower portion thereof;

means for connecting a front portion of said container to a grain bin sidewall whereby said container extends into said grain bin;

means connected to said container for selectively removing said front wall;

extension means connected to a front-bottom portion of said container, for extending forwardly the effective bottom of said container whereby said extension means serves as a spout for allowing grain to pour into a grain sampling device;

and wherein a grain port is disposed in a top portion of said laterally extending walls of the container and said device includes means for opening and closing said grain port.

2. A grain viewing and sampling device as claimed in claim 1 wherein said means for opening and closing said grain port includes means for controlling the flow of grain through said grain port.

3. A grain viewing and sampling device as claimed in claim 1 wherein said means for opening and closing said grain port comprises a gate valve disposed over said grain port.

4. A grain viewing and sampling device as claimed in claim 1 wherein said extension means comprises a plate having upper side edges and a shape complimentary to the bottom of said container;

two grooves formed on the bottom of said container; and

the sides of said plate being slideably received in said grooves.

5. A grain viewing and sampling device as claimed in claim 4 wherein a front portion of said plate has a handle attached thereto.

6. A grain viewing and sampling device as claimed in claim 5 wherein said handle is a curved rod, the ends of which are secured to the front upper side edges of said plate.

7. A grain viewing and sampling device as claimed in claim 1 wherein said front wall is formed of a transparent material.

8. A grain viewing and sampling device as claimed in claim 1 wherein said container is of a generally cylindrical configuration.
