Abstract
ABSTRACT OF THE DISCLOSURE
Dry particulate material, such as seed or fertilizer is distributed in the soil of an agricultural field. The particulate material is carried in a hopper and delivered from the hopper using an auger type conveyor. A manifold associated with a section of the auger tube distributes the particulates to several supply tubes, each which in turn supplies the particulates to a delivery tube associated with a furrow opening sweep.
The conveyor supplies particulate material to the mani-fold at a rate in excess of the feed rate of the material to the soil, so that there is an excess and the manifold is always full. The excess material is returned to the hopper through an overflow tube. The system is gravity flow, with seed and fertilizer being discharged from the manifold by gravity and transported along the supply tube by gravity.

Description
~ 3 ~ 6 SEEDING AND DEEP BAND FERTILIZER ASSEMBLY
FIELD OF_THE INVENTION
The present inventiun relates to an apparatus and a method for distributing particulate m~terial into soil.
BACKGROUND
Various systems have been used in the past for distributing particulate material such as seed and dry fertilizer in agricultural fields. The present invention is concerned with the provision of a novel apparatus and method for this purpose.
SUMMARY
According to one aspect of the present inven-tion there is provided an apparatus for distributing dry particulate material into soil, comprising:
a container for the particulate material;
conveyor means for drawing particular material from the container;
manifold means operatively associated with the conveyor means for receiving particulate material therefrom;
a plurality of supply tubes leading from the manifold means for carrying particulate material ~ !
:' '~ . ' ~ .~ , 1 3 ~
therefrom; and overflow means for receiving excess particulate material from the manifold and returning the excess to the container.
The use of an overflow mechanism in this system allows the manifold to be supplied with seed or ferti-lizer at a rate in excess of that required, so that the manifold will remain full and uniform supply conditions from the manifold will prevail.
In preferred embodiments, the conveyor is an auger conveyor with a series of holes along one section of the auger tube. The manifold covers that section of the auger tube and has multiple outlets receiving material from the respective holes and connected directly to the supply tubes, which in turn lead to individual delivery tubes associated with respective furrow openers.
The manifold may be adjusted along the auger tube to vary the registration of the outlets with the holes in the auger tube. This controls the rate of supply to the supply tubes.
According to another aspect of the present invention there is provided a method of distributing particulate material into soil at a predetermined rate, comprislng:
. -~, drawing particulate material from a supply thereof at a supply rate in excess of ~he predetermined rate;
feeding the particulate material to a manifold at the supply rate;
discharging particulate material from the manifold into plural supply tubes at the predetermined rate;
supplying particulate material from each supply tube to a soil insertion means for inserting the parti-cular material into the soil; and returning particulate material supplied to the manifold in excess of said predetermined rate to the supply thereof.
Preferably, the particulate material is fed by gravity from the manifold through the supply tubes to the delivery tubes.
BRIEF DESCRIPTION OF THE DR~WINGS

Figure 3 is a detailed view, partially in section, of part of an auger conveyor and a manifold;
and Figure ~ is a view along line IV - IV oE Figure 3.
DETAILED DESCRIPTION
Referring to the accompanying drawings, there is illustrated an apparatus 10 of the seeder or ferti-lizer type for distributing dry particulate material into the soil of agrlcultural fields. The apparatus includes a frame 12 with a fixed centre section and two wings 14 that may be folded up for transport purposes. The mechanism for folding the wings is not il~ustrated for the purpose of clarity. Such arrangements are known.
The frame 1~ is supported on six wheels 16. It carrles several spring shanks 18 mounting respective furrow opening sweeps 20 (Figure 2~. The frame may be ralsed and lowered on the wheels 16 to control the depth of the sweeps or to raise them out of the ground for transport purposes. The mechanism for this is not illustrated, but appropri~te systems are known.
Each sweep 20 is associated with a delivery tube 22 that delivers particulate material into a furrow immediately behind the sweep. The delivery tubes are fed , ~ :
. , -` ~ 3 ~
with particulate material by supply tubes 24 that extend upwardly from the respective delivery tubes 22 to a mani-fold 26 carried by an auger tube 28 of an auger conveyor 30. The conveyor 30 includes, in addition to the tube 28, an auger 32 driven by an hydraulic motor 34. The conveyor 30 draws partlculate material from a hopper 36 and discharges excess particulate material at the end remote from the hopper into an overflow tube 38.
As illustrated most particularly in Figure 2, the hopper has a main chamber 40 and a smaller overflow chamber 42 into which the overflow tube 38 discharges.
The auger inlet 44 extends into both of these chambers so that particulate material from both can be delivered to the manifold 36.
Within the main hopper chamber 40, the auger tube 28 is surrounded by a sliding sleeve 46 that may slide up and down on the auger tube to open or close the auger inlet 44 within the main chamber 40. The sleeve is connected to a rod 48 that projects out of the hopper through a hole 50 in the end wall 52 of the overflow chamber 42. A series of notches 54 in the rod 48 engage the edge of the hole 50 to prevent undesired longitudinal movement of the rod and the associated sleeve 46. The sleeve serves to control the rate of supply of particu-..~

late material from the hopper to the manifold 26.
Referring to Figures 3 and 4, the manifold 26includes a partial sleeve 60 fitted on the auger tube 28 and open along the top. Two rows of outlet ~ubes 62 are connected to the sleeve 60 on the bottom side of the conveyor. The two rows of tubes diverge slightly and the tubes of one row are off-set longitudinally of the sleeve with respect to the other. Each tube registers with a hole 6~ in the auger tube 28 so that particulate material in the auger tube will fall through the holes 64 and into the tubes 62 for delivery to the supply tubes. On the top side of the auger tube 28, opposite the holes 64, is a clean-out opening 66 that provides access to the interior of the auger tube so that any blocked holes 64 or tubes 62 can readily be cleared. The clean-out opening 66 is normally covered with a flexible cover 68 held in place by straps 70.
At the bottom end of the manifold sleeve 60 is a rod 72 that projects along the auger tube 28, through a sleeve 74 clamped to the tube. The lower end of the rod 72 is threaded and is held in place in the sleeve by two lock nuts 76. This arrangement allows the adjustment o~
the manifold sleeve 60 along the auger tube to vary the registration of the tubes 62 with the holes 64. This in .

,~ . ~ ' . ' ' 1 3 ~
turn varies the amount of material falling from the interior of the auger through the holes 64 into the tubes 62 and thence the supply tubes, to vary the rate at which seed or fertilizer is delivered to the delivery tubes.
In use, the auger is operated at a rate that will provide an excess supply of particulate material to the manifold 26. This ~eeps the mani~old full so that there will be a uniform discharge from the manifold into the various supply tubes 24, at a predetermined rate.
The excess particula~e material supplied to the manifold is returned to the hopper through the return tube. The position of the sleeve 46 is adjusted using the rod 48 to vary ths exposed size of the auger inlet and therefore the rate of supply of particulate material to the manifold 26.
While one embodiment of the present invention has been described in the foregoing, it is to be under-stood that other embodiments are possible within the scope of the present invention. It is, for example, possible to provide a seed or ferti].izer supply unit that could be pulled behind any implement for supplying particulates to the implement. Where additional feeding capacity was desired, two or more auger conveyors could be employed. The invention is therefore to be considered .. .
