Description
. "TRA~SPORTING A~ID UNLOADING DEVICE"
_ BACKGROUND OF THE INVENTION
This invention relates to a transporting and unloading device which may be of the type known as a drill fill in which there is provided a container for receiving seeds or fertilizer together with an auger for lifting:the material out of the container and depositing it in the hopper of a seed drill.
~ Devices of this type have been manufactured for many years and in one arrange~ent which has become pop-ular in recent years there are provided two such contain-ers arranged ~ide by side, each being generally rectang-ular and provided with a hopper bottom which again is generally rectangular leading to a flat base. An auger is provided which passes through an upper wall or cover of the container so that most of its length extends inwardly of the container down to the flat base for lift-ing the material which collects at the base out of the container for deposit from the contalner. The arrange-.ment of auger passing through the cover is preferred in--order to allow the containers and framework to be fitted within a conventional truck box with the auger exposed above the top of the truck box and not interfering in any `i~
....
~2~2~
way with the sides of the truck box.
This arrangement has been generally satis-factory and has been commercially successful over many years. However, in view of the fact that the auger pass-es through the cover wall of the container with the flighting of the auger cooperating with the bottom or base of the container, it has been difficult to withdraw all the material from the container even with the lower walls converging inwardly to a relatively small base area to collect the material. Thus, material tends to be left at the bottom of the container which is both wasteful and can in some circumsta~ces cause corrosion o thP auger flighting and lower portion of the container.
SUMMARY OF THE I~VE~TION
-It is one object of the present invention, there~ore, to provide an improved container of this type which avoids or reduces the dificulties obtained by material being left in the lower portion of the contain-er.
According to the invention, therefore, there is provided a material transporting and unloading device comprising a container having lower walls which converge to a base and an auger having a flighting and surrounding tube, the tube projecting from a position inward of the lower walls to a position adjacent the base whereby the flighting can withdraw material converged at the base by the ~ower walls through the tube upwardly from the base for discharge, the base including a compartment downward-ly of the ~.ower walls into which the material can fall from the lower walls ~o as to collect for withdrawal by said flighting and opening means at the bottom o the compartment whereby a last remaining portion of the material can be extracted.
The invention is particularly applicable to the above stated dual container arrangement where one of the containers is used for seeds while the other is used for fertilizer. In this arrangement the auger extends down-wardly from a position through the top cover but adjacent one sidewall, inwardly of ~he container to the base where it extends into the compartment defined by vertical side-walls to assist in leaving a reduced proportion of mater-ial in the container. The last remains of the material can b~ extracted through the opening and suitably col-lected.
With the foregoing in view, and other advan-tages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference - .4 -; to the accompanying drawings forming a part hereof, which includes a description of the best mode known to the applicant and of the preferred typical embodiment of the principles of the present invention, in which:
DESCRIPTION CF THE DRAWINGS
Figure 1 is an isometric view of a container and delivery device according to the invention.
Figure 2 is a cross-sectional view taken on a longitudinal axis of the container structure of Figure 1 looking from the lethand side of the device as shown in Eigure 1~
In the drawings like characters of reference indicate corresponding parts in the different figures.
DETAILED DESCRIPTION
A drill fill device, is shown in the drawings and comprises a pair of substantially square containers and 11 which are coupled together side by side in tandem. Each container 10, 11 comprises four sidewalls 12 which together form a square or rectangular container haviny upper and lower rusto-pyramidal sides 13, 14 respectively which converge to a top 15 and a base 18 respectively. The top 15 is in the form of a lid which is hinged at 16 and carries a handle 17 so that it can be opened to expose -the inner part of the container for ~2~
loading or observing the material.
Each of the lower sides 14 is generally planar so that they converge downwardly and inwardly to the rectangular base 18. Thus, material collected in the container generally falls down toward the base for collec-tion by an auger 19 and transport from the container.
The auger 19 comprises a tube 20 and a flighting 21 which are supported relative to the container by passing through a collar 22 in an upper wall 13 and by a frame which connects the lower end of the tube to the lower walls 14 adjacent the base 18.
At the base 18, a compartment 24 is provided defined by rectangular planar vertical walls 25 which create a box hanging or depending downwardly from the base into which material can fall from the lower side-walls 14. The depth of the box or compartment ,24 is just sufficient to provide a layer of material which can be grasped by the portion of the flight 21 which is exposed from the lower end of the tube 19. The bottom of the box or compartment 24 is defined by a planar sheet 26 which is mounted in slides 27 so that it can be slid rightwardly as shown in Figure 2 by a handle 28.
The containers 10, 11 are mounted on a frame 29 which supports the containers relative to a supportsur-~ ' ~20Z59~
face with beams 30 contacting the containers under the -inclined lower walls 14 to hold the containers upwardly.
The frame is of a type which can allow the whole struc-ture to be supported on separate ground whePls for towing as a trailer unit or alternatively the frame structure can be inserted into a conventional truck box with the containers carried by the truck box so that the sides lie closely adjacent or touching the sides of the trucX box.
The height of the containers and the frame are sufficient so that the top of the auger tube 20 comes above the side of the truck box so that a discharge spout 31 can extend downwardly from the top of the truck box for filling a seed drill hopper in conventional manner. The spout 31 can include a flexible section 32 and a telescopic section 33 as is well known.
In operation, the containers are filled with seed or fertili~er or one oE each following which the material is transported to the required location. At this time the auger is operated so the flighting turns and lifts the material from the container for discharge through the spout 31. -When the discharge is almost complete, the remaining material falls down the inclined sides 14 into the compartment or box 24 from which it can be withdrawn .
~2~
by the exposed end of the flighting 21. The confining of the material into the square or rectangular box 24 enables more material to be extracted th~n would be the case in the conventional arrangement where a flat base connects the lower most extent of the walls 14~
If it is desired to completely empty the container so that it can be stored or a different mater-ial transported, the last remnants or remains of the material left in the compartment 24 after the flighting has ceased to be able to draw out further material from the box 24 is removed by opening the sheet 26 on the slides 27 so the material can be caught in any suitable container or merely deposited on the grou~d if not required.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying speciication shall ~e interpreted as illustrative only and not in a limiting sense.

DETAILED DESCRIPTION
A drill fill device, is shown in the drawings and comprises a pair of substantially square containers and 11 which are coupled together side by side in tandem. Each container 10, 11 comprises four sidewalls 12 which together form a square or rectangular container haviny upper and lower rusto-pyramidal sides 13, 14 respectively which converge to a top 15 and a base 18 respectively. The top 15 is in the form of a lid which is hinged at 16 and carries a handle 17 so that it can be opened to expose -the inner part of the container for ~2~
loading or observing the material.
Each of the lower sides 14 is generally planar so that they converge downwardly and inwardly to the rectangular base 18. Thus, material collected in the container generally falls down toward the base for collec-tion by an auger 19 and transport from the container.
The auger 19 comprises a tube 20 and a flighting 21 which are supported relative to the container by passing through a collar 22 in an upper wall 13 and by a frame which connects the lower end of the tube to the lower walls 14 adjacent the base 18.
At the base 18, a compartment 24 is provided defined by rectangular planar vertical walls 25 which create a box hanging or depending downwardly from the base into which material can fall from the lower side-walls 14. The depth of the box or compartment ,24 is just sufficient to provide a layer of material which can be grasped by the portion of the flight 21 which is exposed from the lower end of the tube 19. The bottom of the box or compartment 24 is defined by a planar sheet 26 which is mounted in slides 27 so that it can be slid rightwardly as shown in Figure 2 by a handle 28.
The containers 10, 11 are mounted on a frame 29 which supports the containers relative to a supportsur-~ ' ~20Z59~
face with beams 30 contacting the containers under the -inclined lower walls 14 to hold the containers upwardly.
The frame is of a type which can allow the whole struc-ture to be supported on separate ground whePls for towing as a trailer unit or alternatively the frame structure can be inserted into a conventional truck box with the containers carried by the truck box so that the sides lie closely adjacent or touching the sides of the trucX box.
The height of the containers and the frame are sufficient so that the top of the auger tube 20 comes above the side of the truck box so that a discharge spout 31 can extend downwardly from the top of the truck box for filling a seed drill hopper in conventional manner. The spout 31 can include a flexible section 32 and a telescopic section 33 as is well known.
In operation, the containers are filled with seed or fertili~er or one oE each following which the material is transported to the required location. At this time the auger is operated so the flighting turns and lifts the material from the container for discharge through the spout 31. -When the discharge is almost complete, the remaining material falls down the inclined sides 14 into the compartment or box 24 from which it can be withdrawn .
~2~
by the exposed end of the flighting 21. The confining of the material into the square or rectangular box 24 enables more material to be extracted th~n would be the case in the conventional arrangement where a flat base connects the lower most extent of the walls 14~
If it is desired to completely empty the container so that it can be stored or a different mater-ial transported, the last remnants or remains of the material left in the compartment 24 after the flighting has ceased to be able to draw out further material from the box 24 is removed by opening the sheet 26 on the slides 27 so the material can be caught in any suitable container or merely deposited on the grou~d if not required.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying speciication shall ~e interpreted as illustrative only and not in a limiting sense.
