Abstract
ABSTRACT OF THE DISCLOSURE
The system is designed to be used in conjunction with conventional tillage equipment such as one-way discers, deep tillage chisel ploughs, field cultivators and the like and can be utilized to plant seed and/or apply fertilizer, herbicides or both. It consists of a separate wheeled trailer carrying the weight of the seed, fertilizer, herbicides and the like thereby eliminating any weight change from the seeding machine.
The seed or granular chemicals are entrained in air stream and conveyed by headers and conduits to the seeding boots or spouts.
Each component is metered from a tank by an upwardly inclined auger assembly driven by a variable speed orbital motor, and deposited into the air stream carried by a main conduit. A seal between the main conduit and the individual tank is usually effected by the head of material in the inclined auger assembly but if desired, the tank can be pressurized particularly if very fine chemical material such as a herbicide, is being used.

Description
BACKGROUi\lD OF Tlli~: INVE:NTION
~his invention relates to new and us-ful improvements air in/seeding systems, particularly adapted for uae wi.h convention al tillage equipment such as one-wav discerj, _eep tillage chisel ploughs, field cutlivators and the li~e so that the unit can be utilized to plant or fertilize or applv Aerbicide or do all three things at the same time or in comblr.ation~
Conventionally, a seed box is mountec on conver~ional tillage equipment and seed sometimes mixed wit:-. fertilizer, in ~' :
, ` ' ~, .. ' ~ ' -.:
-.
the box, is metered and fed to the planting boots or spouts.
This system suffers from several disadvantages, the principal one of which is the fact that with wide tillage equip-ment normally used, the weight of seed when the box is filled, is considerable and as the seed is used, this weight lessens so -that great difficulty is experienced in maintaining a constant depth of the cultivators and consequently the planting depth of the seed.
, Furthermore it is difficult to mix accurately, the required amount of herbicide and/or fertilizer with the seed and to maintain this mixture in the bulk of the seed as movement over the field often vibrates the contents of the seed box so that ; separation occurs and uneven mixing of the various components takes place. ~-'~ , ' ' SUMMARY OF THE INVENTION
The present invention overcomes these disadvantages firstly by mounting the seed, fertilizer, herbicide and the like on a separate wheeled trailer pulled behind the tillage equipment ~' so that the weight of the material does not effect the load on the cultivating equipment thereby facilitating the maintenance ! of a constant depth of cultivation and subsequently a co.. stant depth of the placement of the seed, fertilizer, herb cide and the - like~
~ Another advantage of the present system is the separa-' tion of the various components such as seed, fertilizer, herbi-cides and the like into separate tanks on the trailer so that accurate proportions of the various components can be metered into the air stream which conveys the components to the boots or spouts of the tillage equipment.
One aspect of the invention is therefore to provide a seeding assembly for use with conventional equipment such as one-way discers, deep tillage chisel ploughs, field cultivators and the like and which includes seed depositing means such as boots and spouts adjacent the ground engaging tillage components;
comprising in combination at least one tank for containing seed, fertilizer, herbicide and the like, a main duct for carryin~ a conveying air stream under pressure, a main header operatively connected to said main duct, at least one secondary header opera-tively connected to said main header, conduit means extending from said secondary header to said seed depositing means, an upper inclined auger assembly extending from said tank to said :. main duct whereby material within said auger assembly acts as an air seal between said main duct and said tank, an a variable speed motor operatively connected to said auger assembly.
.; .
Another aspect of the invention is to provide a.device of the character herewithin described which is simple in construc-tion, economical in manufacture and which can readily be changed from one machine to the other with the minimum of labour~
With the foregoing in view, and other advantages as .~

10~i0720 DETAILED DESCRIPTION
. _ . .
Proceeding therefore to describe the invention in de-tail reference should first be made to Figure 1 in which reference character 10 illustrates generally, conventional tillage equip-` as ment such/a one-way discer, deep tillage chisel plough, field cultivator and the like all of which are conventional.
normally This conventional equipment is/provided with boots or spouts 11, depending upon the type of equipment, through which or seed /fertilizer, is deposited into the ground immediately behind the ground engaging tillage component (not illustrated) and which of course may take the form of a disc, plough point, or the like.
In air seeding equipment, it is usual to provide a source of power 12 driving a fan assembly 13 which supplies air ;~ under pressure to a main duct or conduit 14 and which in turn leads to a main header assembly collectively designated 15.
From there, secondary ducts or lines 16 extend to secondary ,c headers collectively designated 17 from which extend boot or spout lines or conduits 18, to the aforementioned boots or spouts 1i.
. :
The main and secondary headers may take the form of - 20 the headers shown in Figure 3 for example in which the main duct 14 (or secondary duct 16) connect to the lower end of the header tube 19 which extends vertically upwardly to the distribution head 20 from which the secondary lines 16 (or boot lines 18), extend in a radial fashion. The inner surface of the header tube 19 is preferably corrugated as indicated at 21 in order to maintain the :
11~)6~720 entrained material in the air stream, centrally of this - tube particularly when side hill seeding is taking place, thereby ensuring even distribution of the entrained mate-rial, through the secondary lines 16 (or boot lines 18) as the case may be.
Figure 4 shows an alternative header construc-tion in which the header tube l9A also extends vertically but narrows in diameter from the lower end 21, towards the upper end 22.
This particular construction is provided with a domed upper end 23 to which the secondary lines 16 (or boot lines 18) are connected, the dome assisting in the even dis-tribution of the entrained material to the secondary lines.
, ' ,` '.
The inner surface of this particular embodiment is provided with a plurality of spaced and parallel annular ribs 24 having upwardly and inwardly curved inner surfaces 25 and concave upper surfaces 26 all of which assist in the maintenance of the entrained material centrally of the tube l9A regardless of the attitude of the headers due to sloping ground surfaces and the like.
, However, any form of header or secondary header can be used as desired.
. .
~,~;
A tank collectively designated 27 is mounted on a wheeled trailer 28 pulled behind a tractor 29 as shown in Figure 5 with the tillage equipment 10 being connected behind ` the trailer 28.
Alternatively of course an depending upon the tillage equipment, the tillage equipment can be connected to the tractor 29 with the trailer 28 being linked behind the tillage equipment.
It will also be noted from Figure 5 that the main and secondary headers are located on the tillage equipment. It will of course be appreciated that, if desired, this part-of the struc-ture may be mounted on the trailer 28 if desired.
The tank 27, in this embodiment, consists of three individual compartments 28, 29 and 30 one of which may contain two ---grain to be seeded, the other/of which may contain granulated fertilizer and herbicide respectively.
~.
. 15 Each container 28, 29 and 30 is provided with indownward- ~-; ly and inwardly sloping wall portions 31 forming what is conven-tionally known as hopper bottomed compartments and each compartment is provided with an auger assembly collectively designated 32.
., .
The auger assembly includes an auger tube 33 having an auger flight component collectively designated 34 journalled for rotation within the tube. This auger flight component includes _ .~ - :
.. . .
an auger shaft 35 extending lengthwise through the tube and ex-tending through the upper end to be connected to a source of power 36 as will hereinafter be described.
An auger flighting 37 is secured to the shaft 35 and extends from the lower intake end 38 of the tube, to adjacent a point of connection of the auger tube to the aforementioned main line or duct 14.
It will of course be appreciated that the auger tube 33 extends into the compartment through the side wall thereof with the lower intake end 38 being adjacent the base 39 of the '. compartment 28, 29 or 30.
-. .
In this embodiment, the connection between the auger tube 33 and the main duct 14 is by opening out of the tube through.
the wall of the duct.as shown schematically in Figure 2 but of course it will be appreciated that individual downwardly extending conduits can be provided between the exit 40 from the tube 33 and the main duct 14 which is of course carrying air under pressure from ihe fan 13.
.
.
With the auger flighting 37 terminating adjacent the duct 14, material from the tank is augered upwardly and deposited by gravity into the air stream carried by the duct 14 and is en-trained thereby.
Under normal circumstances, the material within the auger assembly below the duct 14 acts as an air seal between the main duct 14 and the interior of the compartment 28, 29 and 30 and prevents blow-back from occurring.
However under certain circumstances, particularly when used with very fine granular material such as is often found in herbicides, it desirable to pressurize the compartments above the material as shown schematically by the dotted line 41 extend-ing between the fan and the other side of the compartments. Under these circumstances, the closure 42 through which the compartments are filled, should be sealed.
Referring back to the source of power 36 for the auger assemblies, this preferably consists of an hydraulic orbital motor driven by hydraulic fluid provided by a pump 42 and hydrau-lic lines 43 together with reservoir 44 in the usual way. -In Figure 2, a valve 45 is shown for varying the speed of the orbital motor but the orbital motor may be controlled by a flow divider or variable displacement pump (not illustrated) and a solenoid on-of switch (also not illustrated) operated from the tractor seat.
Being able to vary the speed of the orbital motors, not only enables the operator to select the desired seed rate but also~~~ -enables him accurately to control the amount of fertilizer and/or herbicide being mixed with the seed entrained in the air stream carried by the main duct 14.
: Since various modifications can be made in my inven-tion as hereinabove described, and many apparently widely dif-ferent 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 specifi-cation shall be interpreted as illustrative only and not in a limiting sense.
