Abstract
An apparatus to form a part of an agricultural planting implement is provided to simplify and enhance its function.
There are tanks provided for supplying material such as seed and fertilizer to be planted. The seed and fertilizer are elevated from the tanks by a separate flexible positive feeding conveyor to two or more respective chambers where a single wheel or cylinder in each chamber meters the material conveyed to the chamber. The metered material then enters several guide tubes where it is gravity fed to a furrow made in the ground by the implement. Each of the chambers includes an expandable portion to indicate whether or not they are functioning properly. When an implement with folding side wings are used an air assist and/or a shaking clamp may be applied to the gravity fed guide tubes to ensure proper placement of the materials.

Description
' ~
- -~?as60 This invention relates in general to a material handling and metering system and in particular to delivering from a supply one or more types of particulate material in specific quantities to a specific location.
- To optimize crop yields it is necessary to uniformly distribute plant seed and accompanying fertilizer in a most advantageous location in the soil.
In an effort to carry out the above proper placement there was originally used a ground engaging implement having a supply box or container for the particulate material with several metering means at the bottom thereof which metered ., .~_ ._ ~- the material such as seed and/or fertilizer to a drop tube which placed the material in an opening or furrow made by the ground engaging implement. This type of implement however, had its limitations as far as filling, clean out, limited width and supply storage were concerned.
What is commonly used today is a tool bar implement where the particulate material supply is provided by a connected separate wagon or a tank that is mounted on the tool bar. The particulate material is metered and placed in communication with an airstream provided by a blower so that the particulate material may be entrained and carried to distribution apparatus whereby the material in the stream may be divided into a plurality of smaller streams and conveyed to a --- desirable location prepared by the ground engagement of the tool bar implement. The trend toward the air seeder proved to have certain advantages such as large supply tanks easy to fill and empty, wide rank spacing and being easily adapted to wing type implements. There are, however, certain problems associated with this type of implement such as high horsepower ~J
21~56 requirements, high material flow rate, high costs, seed damage, poor placement, moisture problems and poor meter - location.
The closest prior art known to applicant is found in United States patent 4,473,016, Sept. 25/84 to Gust and Canadian patent 949,391, June 18/74 to Seifert.
Patent "016~ shows the typical air seeder with a towed wagon providing the supply of particulate material, a bulk metering slide door, a ground driven spiral tooth metering cylinder, viewing windows and a particulate air entrainment and distribution system. To obviate the problems previously set forth regarding air seeder equipment applicants device does nothave the high initial and maintenance cost of the air entrainment and distribution system with its high horsepower requirements, the high material flow rate with its inherent problems such as damaged seed and poor placement. Applicant basic~lly overcomes all of these problems by a simple positive mechanical elevation of the particulate material to a metering chamber that meters the particulate into gravity drop tubes.
Patent ~391~ shows a gravity feed of the particulate material from tanks on the implement. This arrangement could not be ~ easily adapted to a towed supply tank wagon as can applicants device. The patent also teaches an intricate metering assembly for each drop tube while applicants device provides a simple metering chamber with metering cylinder to cover a multiplicity of drop tubes.

~' ~
r 2~2~6o The present invention provides a novel material handling and metering system to be used as part of an agricultural planting implement. The material is generally two kinds of particulate material that is to be placed in the ground. A supply of the materials can be in a tank wagon towed behind or placed in front of the implement or in fact can be in tanks carried by the implement. The materials in the tanks are elevated by a flexible positive feeding means, generally ground driven, to two or more chambers where it is metered by a single wheel of cylinder in each chamber and placed in a multiplicity of gravity fed guide tubes which direct the material to a furrow made in the ground by the implement. The chambers each include an expandable portion to indicate whether or not they are functioning properly. For an implement with fold up side wings an air assist or a shaking clamp may be applied to the gravity feed guide tubes to ensure proper placement of the materials. The metering wheel or cylinder is formed as having a spiral or segmented tooth shape for uniform metering and an a~justable metering edge is placed adjacent the wheel or cylinder.
In view of the above summary it is readily discernible that a primary object of the present invention is to provide an effective yet simple material handling and metering system.
A further object of the present invention is to provide a material handling and metering system that can be adapted to almost any location of the particulate material supply tanks due to the positive flexible feed means from the tanks.
A further object of this invention is to provide a metering chamber, having a single matering wheel or cylinder, that is fed by the positive flexible feed means and discharges into ;~ :
5~
a multiplicity of guide tubes.
;-A further object of this invention is to provide a metering chamber, a portion thereof which is flexible to indicate proper flow of the material therein.
Yet a further object of this invention is to provide bulk metering by control of the positive flexible feed means.
It is yet a further object of this invention to provide wide pivoted wing implements with air assist and guide tube shakers to ensure proper placement of all the materials.
These and other objects of the present invention will become - readily apparent as the following description is read in conjunction with the accompanying drawings wherein like reference numerals indicate like elements throughout the several views.
Figure 1 is a partial schematic plan view of an implement for handling and metering two different materials.
Figure 2 is a partial schematic of an end elevation of the implement in Figure 1.
Figure 3 is a partial schematic of a metering chamber with discharge guide tubes and guide tube shaker and an air assist.
Figure 4 is an end elevation taken at the cutting plane 4 - 4 in Figure 3.
Figure 5 is a partial schematic of a spiral metering wheel or cylinder used in place of a stepped gear metering wheel or cylinder.
Figure 6 is a partial schematic of a front elevation and end elevation stepped gear metering wheel or cylinder.
21 2~560 Figure 7 is a partial schematic front elevation of an implement for handling and metering two different materials with the Supply storage tanks mounted on the main frame.
Referring now to figure 1 we have an implement with a main central frame 1 with right and left wing frames 2 and 3 respectively, pivotally connected by hinge means 24. It is to be realized that the main central frame 1 is basically all the framework necessary for a smaller complete functioning implement. There is shown towed behind main frame 1 two ---- material supply storage tanks 5 and 6, tank 5 for a first type of particulate material, tank 6 for a second type of - particulate material. These material supply tanks can also be placed in front of the implement or can be mounted on the main frame 1 as shown in figure 7. When towed behind the main frame 1 the supply tanks 5 and 6 are supported by supply tank ground wheels 22 which have a conveyor ground drive 21 connected thereto. This ground drive 21 can control the amount of material being elevated by having included therein a slipDing clutch or belt. A further conveyor drive control 42 is actuated by a pressure sensor 43 generally located in the meter chambers 44, figures 3 and 4, which are basically the inner cavities of all the material meters 11, 12, 13 and 14.
The material supply tanks 5 and 6 are provided with filler covers 40, clean out accesses 41, and material outlets to which conveyors 7, 8, 9 and 10 are connected. The main conveyors 7 and 8 can be rigid in nature when the supply tanks 5 and 6 are mounted on the main frame l as in figure 7.
The main conveyors 7 and 8 and the secondary conveyors 9 and 10 are generally flexible to allow for movement of the towed material supply tanks 5 and 6 relative to the main frame l and f.~ r 2~20560 wing frames 2 and 3 especially when the wing frames 2 and 3 pivoted for transport. The flexible main conveyors 7 and 8 positively convey particulate material to main frame meters 11 and 12 respectively and flexible secondary conveyors 9 and 10 positively convey particulate material to wing frame meters 13 and 14 respectively. Main conveyors 7 and 8 as shown pass through main frame meters 11 and 12 to feed two more wing frame meters (not shown), while secondary conveyors 9 and 10 feed wing frame meters 13 and 14 directly. Wing frame meters 13 and 14 are considered as fed in parallel with main frame meters 11 and 12. All meters for each type of particulate material could be fed in series or parallel. The main frame 1 is supported on main frame ground wheels 23 with the wing frames being supported by similar ground wheels (not shown). The main frame meters 11 and 12 are driven by metering cylinder ground drive 20 mounted on main frame 1, driven by a main frame ground wheel 23 and driving metering cylinder drive wheel 45 shown in figure 3. The wing frame meters are similarly driven from wing frame ground support wheels (not shown). Extending from each meter 11 and 13 are first material discharge guide tubes 15 and from each meter 12 and 14 are second material discharge guide tubes 16.
~ ~ For a clearer understanding of how the different particulate - materials reach their destination reference is now made to figure 2. In this view only material supply tank 6, can be seen with material supply tank 5 located directly behind it.
The tank filler cover 40 is shown on the top with an easily accessable clean out 41 at the rear. The conveyor ground drive is shown at 21 with the conveyor drive control previously described shown in the front as 42. A first type particulate material from supply tank 5 is conveyed by -~1 20~6 ~
conveyor 7 to main frame meter 11 where it is metered and delivered to first material discharge guide tubes 15 which deposit it in a furrow made by a ground engaging tool 25. A
second type of particulate material from supply tank 6 is conveyed by conveyor 8 to main frame meter 12 where it is metered and delivered to second material discharge guide tubes 16 which deposit it in the same furrow made by the ground engaging tool 25 but at a slightly different location.
A more detailed figure 3 which is in fact the meter 13 plus discharge means, for the first particulate material on the right wing frame is basically the same type of meterin~ device used for all the metering. The meter 13 is basically a shell forming a metering chamber 44. At the top of the chamber 44 is a flexible cap 17 which expands when the chamber 44 is full of particulate material which indicate~that the secondary conveyor 9 is functioning. The secondary conveyor 9 which is typical of all the conveyors 7, 8, 9 and 10 as shown in figure 1 can be, for example, belts, chain conveyors, auger cup or bucket elevators or drags. The secondary conveyor 9 shown here is a flexible positive material moving auger using a ~lexible spiral rotating coil 28 within a flexible casing 29. Openings or exit ports 36 are provided in the flexible casing 29 for egress of the particulate material into the metering chamber 44. Mounted on the flexible casing 29 is a pressure sensor 43 which under pressure from the conveyed particulate material in the metering chamber 44 can send a signal to conveyor drive control 42 shown in figure 1 to control the amount of product being elevated.
Once the particulate material enters the metering chamber 44 it is contacted by a step toothed metering delivery wheel or - cylinder 26 driven by a metering cylinder drive gear 45 which 5~
r . .
2l205~0 is driven by a metering cylinder ground drive 20 shown in figure 1. To control the metering process more accurately an adjustable metering edge 30 is provided. The particulate material after passing the metering edge 30 falls into an array of cups 18 which have attached thereto material discharge guide tubes 15 leading into the furrow made by ground engaging tools 25. Depending on the widths and or slope of the right and left wing frames, 2 and 3 resspectively, there may be required additions as shown herein. The first addition shown is in the form of a forced air system which includes an air pump 31 forcing air into a duct 32 that carries it into one or more discharge guide tubes 15. The second addition shown is in the form of a guide tube shaker 33 which is clamped to discharge guide tubes 15 by shaker clamp bolts 19 and actuated by shaker cam 34.
Figure 4 showing the arrangement of figure 3 at the cutting~
plane 4 - 4 clearly indicates the positional relationship of the various elements. The most important relationship is the position of the delivery metering wheel or cylinder 26 relative to the metering chamber 44. Also important is the positional relationship of the adjustable metering edge 30 to the delivery metering wheel or cylinder 26. It is to be noted that the metering edge is adjustably held by metering edge adjuster 35 in various positions over the range denoted at "A~'.
Referring now to figure 5 there is shown a metering spiral wheel or cylinder 27 which could be used to replace the stepped metering delivery wheel or cylinder 26 as shown in figures 3, 4 and 6.
Figure 6 presents no new subject matter but shows basically an ~1 2~6~
enlargement of the stepped metering wheel or cylinder 26 to show how it will provide a gradual metering as does the spiral metering wheel of figure 5. The metering edge 30 has been adjusted to a level providing no resistance to the particulate material entering the cup 18 for transfer to the material discharge guide tubes 15.
Finally referring to figure 7 there is shown for clarity, only a partial schematic of the basic system of figure 1 with the material supply tan~s 5 and 6 now mounted on the main frame 1.
It is under these circumstances where the main conveyors 7 and 8 could be rigid. The material supply tan~s 5 and 6 are supported on the main frame 1 by supply tank supports 37 and meter support 38. The first material main frame meter 11 and -~~
the second material main frame meter 12 are basically the ,~ same as the right wing first material meter shown in Figure 3.
It is under these conditions that an overflow of excess particulate material 46 from meters 11 and 12 could be directed back by gravity to their respective tanks 5 or 6. The material discharge guide tubes 15 and 16 are again shown as directing the particulate material streams to their new location in the furrows prepared in the ground by ground engaging tools 25. With the tanks now mounted on the main frame 1 it is now to be realized that conveyor drives can now have a separate ground drive from the main frame support wheels or be coupled to the metering cylinder ground drive 20.
While figure 1 shows a series connection of meters and a par~llel aonnection of meters~it is realized that for example one conveyor 7 from supply tank 5 could enter the outside end of meter 13 in the right wing and pass therethrough to meter 11 and on to a meter in the left wing frame carrying one type of particulate material. Another conveyor for example conveyor 8 g ~c ~120~
.. . . ..
from supply tan~ 6 could enter the outside end of a meter for a second type of material on the left wing and pass through to meter 12 and on to meter 14 in the right wing. An alternative is of course to have 3 conveyors leaving each tank to supply the three sets of meters.
Various modifications such as size, shape and arrangement of components may be made without departing from the spirit and scope of this invention. The above disclosure shall be interpreted as illustrative only and limited only by the scope of the invention as defined in the following claims.
