Abstract

A grain hopper assembly to receive grain unloaded from a bottom unloading grain transport vehicle. The assembly comprises a shell having opposite ends. An auger is mounted to the shell and conveys grain toward one end of the shell. A hopper tube has an auger contained therein. An attachment housing is at one end of the shell and connects the hopper tube to the shell so that the hopper tube auger operatively communicates with the auger whereby grain at the one end of the shell is received and conveyed by the hopper tube auger.

Claims

1. A grain hopper assembly to receive grain unloaded from a bottom unloading grain transport vehicle, the assembly comprising:

a shell having opposite ends, said shell defining a top opening through which grain is received from a bottom outlet of the grain transport vehicle;

said shell further including a bottom wall and side walls extending up from said bottom wall, and a flexible sealing means, attached to said side walls, for forming a partial seal with the vehicle unloading the grain;

an auger means, mounted to said shell, for conveying grain toward one end of said shell;

a hopper tube having an auger contained therein;

a means, at one end of said shell, for connecting said hopper tube to said shell so that said hopper tube auger operatively communicates with said auger means whereby grain at the one end of the shell is received and conveyed by the hopper tube auger.

2. The grain hopper assembly of claim 1 wherein said shell further includes a bottom defining a pair of wells, a V-shaped landing separating said wells whereby all grain entering the hopper passes into either well.

3. The grain hopper assembly of claim 2 wherein said auger means included a pair of shell augers, each said well containing one of said shell augers, and each of said shell augers being directly driven by a motor whereby each said shell auger conveys grain toward said one end of said shell.

4. The grain hopper assembly of claim 1 wherein a screen permanently covering said top opening.

5. The grain hopper assembly of claim 1 wherein said hopper tube has opposite ends, one of said ends mounted to said connecting means and other of said ends in communication with the destination for said grain.

6. The grain hopper assembly of claim 1 wherein said hopper tube auger is directly driven by a motor.

7. The grain hopper assembly of claim 1 wherein said shell includes a bottom and side walls integral with said bottom, the side wall at said one end of said hopper containing an opening, a flange integral with said side wall and containing a slot extending from said opening, said connecting means including a housing pivotally mounted to said one side wall at said opening, a pin extending from said housing and registering within said slot.

8. The grain hopper assembly of claim 7 wherein said slot is configured so as to define a degree of pivot of said housing relative to said shell.

9. The grain hopper assembly of claim 8 wherein said housing is positioned relative to said hopper at an angle between about 15 degrees and about 30 degrees.

10. The grain hopper assembly of claim 1 further including a wheel means, mounted to said shell, for permitting selective rolling movement of the grain hopper assembly.

11. The grain hopper assembly of claim 10 wherein said wheel means includes a pair of castor wheel assemblies mounted to said shell at one opposite end thereof adjacent the hopper tube, and a wheel mounted to the shell adjacent another opposite end thereof.

12. A grain hopper assembly to receive grain unloaded from a bottom unloading grain transport vehicle, the assembly comprising:

a shell defining a grain collection volume at one end thereof, said shell further having a bottom wall with side walls extending from said bottom wall, a sealing means, attached to said side walls, for forming a partial seal with the vehicle unloading the grain;

a first auger operatively mounted to said shell so that when in operation said first auger conveys grain towards the grain collection volume;

a hopper tube having a second auger operatively mounted therein; and

means, pivotally mounted to the shell, for placing said hopper tube in communication with said shell so that a portion of said second auger is within said grain collection volume.

13. The grain collection assembly of claim 12 wherein said first auger is driven by a first hydraulic motor and said second auger is driven by a second hydraulic motor.

14. The grain collection assembly of claim 13 further including a third auger operatively mounted to said shell so that when in operation said third auger conveys grain towards the grain collection volume, and said third auger is driven by a third hydraulic motor.

15. The grain assembly of claim 14 wherein said second hydraulic motor is in direct receiving communication with a source of hydraulic fluid, said first and third motors are in direct communication and said third motor is in direct exiting communication with the source of hydraulic fluid.

16. The grain hopper assembly of claim 15 further including a flow control means for controlling flow of said hydraulic fluid to said first and third motors, said flow control means being selectable between one condition in which no hydraulic fluid exiting said second motor flows to said first and third motors and another condition in which all of the hydraulic fluid exiting said second motor flows to said first and third motors.

17. The grain hopper assembly of claim 12 wherein said placing means is movable so that the hopper tube is positioned relative to the shell at a range between about 15 degrees and about 30 degrees.

18. A grain hopper assembly for handing grain unloaded from a bottom-unloading grain trailer, the hopper assembly comprising:

a shell having a bottom defining a pair of wells seprated by a V-shaped landing and a grain collection volume, said shell further including upstanding side walls at a periphery of the shell bottom, said side wall adjacent the grain collection volume having an opening therein, a flexible sealing means, attached to said side walls, for forming a partial seal with the grain trailer;

a first auger rotatably mounted to the shell and positioned within one of the wells, and the first auger being driven by a first motor;

a second auger rotatably mounted to the shell and positioned within another of the wells, and the second auger being driven by a second motor;

a hopper tube containing a third auger, and a third motor driving said third auger; and

a housing pivotally mounted to said shell within said opening, said hopper tube mounted to said housing whereby said housing places said hopper tube and said shell in communication.

19. The grain hopper assembly of claim 18 further including means for defining a range of pivot of said hopper tube relative to said shell to be between about 15 degrees and about 30 degrees.
