Description

3~

The present invention relates to a machine, for pneumatic ejection of seed and fertilizers, which is supported on the ground by wheels and comprises at least two storage tanks, separated from each other, in the lower areas of which are arranged outlet apertures from which material, located in the said storage tanks, is introduced, in adjustable amounts and with the aid o~ drivable metering elements~ into ejectors connected to pipelines, and passes to the ground through further pipelines, the pipelines with injectors being connected, through at least one air duct, to at least one blower, the said pipelines extending, in different. 1.engths, at right angles to the direction of travel and ~ornprising outflow apertures at their outer ends which are in spaced relationship to each other, the said outflow apertures extending, at least partly, into colters adapted to move in a vertical plane and arranged on at least one transverse carrier also adapted to move in a vertical plane.
A machine of this kind i.s already known from German OS 24 61 762. This rnachine allows two kinds of material to be ejected simultaneously.
One disadvantage of this machine, however, is that the storage tank, in spite of its great length, has relatively few ou-tflow apertures with metering elements. As a result of this, it is impossible, with a large operating width of the machine, to deposit the seed on the ground in rows as close together as possible.
This machine also has the disadvantage that different materials can be deposited on the ground only jointly. As a result of this, when high percentage nitrogen fertilizers are discharged simultaneously with the seed, the latter is inevitably scorched. This damages the emerging seed and reduces the yield thereof.

It is a prime aim of the present invention to provide a compact machine of relatively short structural length, for large operati.ng widths, on the one hand with the rows of shares arranged close together and, on the other hand, with the ability to discharge various materials simultaneously. The said materials may also be deposited at different locations.
According to the present invention, the afore-mentioned aim is accomplished by providing a machine, for pneumatic ejection of seed and fertilizers, which is supported on the ground by wheels and comprises at least two storage tanks, separated from each other, in the lower areas of which are arranged outlet apertures from which material, located in the said storage tanks, is introduced, in adjustable amounts and with the aid of drivable metering elements, into ejectors connected to pipelines, and passes to the g:round through further pipelines, the pipelines with injectors being connected, through at least one air duct, to at least one blower, the said pipelines extending, is different lengths, at right angles to the direction of travel and comprising outflow apertures at their outer ends which are in spaced relationship to each other 9 the said outflow apertures extending, at least paxtly, into colters adapted to move in a vertical plane and arranged on at least one transverse carrier also adapted to move in a vertical plane, characterized in that the lower parts of the storage tanks extend, with metering elements arranged in the vicinity of the outflow apertures, at right angles to the di.recti.on o~ travel, at least two rows or ejectors, running at right angles to the said direction of -travel, beiny lOcated in front of the wheelsO

As a result of this arrangement, in spite of the short structural length of the machine and withou-t exceeding the legal perrnissible overall width for agricultural vehicles travelling on pub.Lic roads and highways, it is possible to accommodate, in simple fashion, the very large number of metering elements and injectors, required for rows located close together and for large operating widths.
A particularly compact design is obtained by arranging the pipelines in at least two planes arranged at least partly one below the other. In this case, the pipelines connected to the front row of injector.s may be arranged, with advantage, closely below the rear row of injectors arranged in front of the wheels. A short structural length is also achieved by staggering the rows of injectors arranged in front of the wheelsO
Another substantial improvement in the matter of the simultaneous ejection of fertilizers and seed may be obtained by arranging an additional row of injectors above the wheels-In order to be able to deposit seed in the ground with the aid of colters~ and to be able to spread fertilizer independently as soon as the seed has been ejected, the outle,~
apertures of the pipelines connected to one row of injectors extend to behind the colters arranged in transverse rows, and baffle plates, known from German Patent 23 35 167 are arranged in front of the said outlet apertures- ~hus seed is placed in the ground and fertili.zer is spread over the surface of the ground in a single operation~ ~his produces sub-stantially fewer vehicle tracks on the ground which not only saves operating time but also increases the yield.
~ nother way of achieving the aim of the invention is to provide a machine for pneumatic ejection of seed and 3~
" .

fertilizers, which is supported on the ground by wheels and ~omprises at least two storage tanks, separated from each other, in the lower areas of which are arranged outlet apertures from which material, located in the said storage tanks, is introduced, in adjustable amounts and with the aid of drivable metering elements, into ejectors connected to pipelines 3 and passes to the ground through further pipelines, the pipelines with injectors being connected, through at least one air duct, to at least one blower, the said pipelines extending, in different lengths, at right angles to the direction of travel and comprising outflow apertures at their outer ends which are in spaced :relationship to each other, the said outflow apertures extending, at least partly, into colters adapted to move in a vertical plane and arranged on at least one transverse carrier also adapted to move in a vertical plane, characterized in that the lower parts of the storage tanks with metering elements arranged in the vicinity of the outflow apertures, extend at right angles to the direction of-travel of the machine, in that at least one row of in~ectors, extending at right angles to the direction of travel, is arranged i.n front of the wheels, and in that a further row of injectors, also extending at right angles to the direction of travel of the machine, is arranged above the wheels.
This arrangement is particularly effective for use with -the "no-till-drill" process. According to one preferred example of embodiment, seed and fertilizer are adapted to be fed to the row of injectors located in front of the wheels by means of two separate rows of metering elements. This makes it possible to spread 7 simultaneously with the seed, a combination fertilizer which improves growth and yield.

A particularly simple supply of air from the blower to the individua.l air ducts i.s obtained by arranging the air shaft connecting the said ducts in the lateral vertical side parts-Provision is also made, according to the inventi n,for the pipelines connected to the rows of injectors arranged in front of the wheels to run above the wheels and below the walls of the storage tanks to the rear end of the machine, the wheels used having a large diameter of more than 1 m. It is also possible to arrange the wheels with tracks of different widths, so that the optimal track width for the given cir-cumstances can be adjusted.
If the machine is then also equipped with an inter-changeable transverse beam, disclosed in German Patent 29 22 185, for the colters, the said colters, and the entire transverse beam, can easily be replaced with different colters and thus converted to other use, for example, from the conventional drill to the "no-till-drill" method. This conversion 9 and the replacement of the transverse beam and colters, may be simplified by connecting the pipelines to at least one quick-disconnect coupling.
The machine is easily converted from the transportation to the operative confi~uration by dividing the transverse beam into three parts, as already known from German OS ].9 34 247. In this case, the central part is arranged to move on the machine in a vertical plane, -the said central part carrying booms arranged to pivot about axes arranged at least approximately in the direction of travel and being supported on the ground by wheels-Furthermore, the said central part, with the booms, is arranged to pivot in a vertical plane about an axis located at a distance in front of the transverse beam and running at ~ight angles to the direction of travel. One particular ad~antage of this latter characteristic is that the central part, with the booms and colters, can be pivoted upwardly for making a t~lrn at the end of the field, thus lifting the colters from the ground~
In one aspect of the present invention there is provided a machine or the automatic discharge of seed and fertilizer, the machine running over the ground on wheels and comprising at least two storage tanks, at least partly separated from each other, in the lower areas of which are arranged rows of outlet apertures whence the material located in the storage tanks is introduced, with the aid of drivable metering elements, in adjustable amounts, into injectors connected to pipelines partly located in front of the running wheels, the material ~eing passed to the ground through pipe-lines, the latter, with the injectors, being connected by at least one air duct to a blower and extending, in different lengths, at right angles to the direction of travel and comprising, at their ends, which are spaced from each other, discharge apertures which open, at least partly, into coulters arranged to move in a vertical plane on at least one transverse beam moving in a vertical plane, characterized in that, in a manner known per se, the lower areas o the storage tanks with metering elements arranged in the vicinity o~ the outlet apertures, each ex~end at right angles to the direction of travel, in that at least two rows of injectors extend at right angles to the direction of travel, and ,in that at least one of these rows of injectors is located in front of the running wheels.

The invention is illustrated by way of example in the accompanying drawings wherein:
FIGURE 1 shows a machine in accordance with the present invention, in side elevation and in cross section I - I, FIGURE 2 shows the machine shown in Fig. 1, from the rear and in cross-section II - II
and FIGURE 3 shows a further machine in accordance with the pxesent invention, in side elevation and in cross~section I - I as in Fig4 1.
r~he machine comprises three storage tanks 1, 2 and 3. These are ~cco~nodated in a frame 5 with the aid of vertical lateral parts 4 and are supported on the ground by wheels 6 approximately 1 m in diameterO Arranged in lower parts 8 of the said storage tanks are rows of outlet apertures 10 rllnning at right angles to the direction of travel 9 of the machine. Located in the area in front of outlet apertures 10 are metering elements 11 by which the material located in the individual storage tanks is introduced, in a manner known per se and therefore no~ shown, into injectors 13 connected to pipe-lines 12, the said injectors being arranged in a row running at right angles to the direction of travel, side by side and below the said metering elements. Individual injectors 13 are connected, in each row, to an air duct 14 running at right angles to the said direction of travel~ The said air duc-ts are connected by air shafts 15 loca-ted in lateral parts 4, to blower 16 arranged at the front of the machine, the said blower being driven from the take-off shaft of the tractor towing the machine~

Located in staggered arrangement in front of wheels 6 are two rows of injectors 13l, 13" running at right angles to the direction of travel 9, so that material delivered by metering elements 11 reaches inlet hopper 17 for injectors 13.
Moreover, pipelines 12l, connected to the front row of injectors 13', run closely under the rear row of injectors 13". Material delivered by metering elements 11 arranged in front o~ outlet apertures 10 from storage tank 1 is passed by guide elements 18 to inlet hopp~rs 17 for row 13' of injectors.
Row 13" of injectors is arranged at an angle of 45 in front of wheels 6, i.e. as close]y as possible in front of the said wheels.
Pipelines 12' and 12", connected to injector rows 13l and 13", run above wheels 6 and below walls 19 of storage tanks
2 and 3, to the rear end 20 of the machine where they are connected to quick disconnect coupling 21 which is in the form of a frame 22 and is secured to frame 5 by mountings 22.
Arranged above wheels 6 is a further row 13"l of injectors located under outlet apertures 10 and metering elements 11 of storage tank 3. Pipelines 12"', connected to row 13"' of injectors, also run to quick disconnect coupling 21. Pipelines 24, fitted with outflow apertures 23, are com-bined at their front ends into a frame 25 in the form of a quick disconnect coupling. The two quick disconnect couplings 21 and 25, connecting pipelines 12 and 24 together, are adapted to be locXed together with central closure 2~ in the form of thumb screws.
Transverse beam 27 is mounted at the re~r end of the machine in such a manner as to pivot in a vertical plane about an a~is 28 locaced at a distance from the said beam and running at right angles to the direction of tra~el. The said ~eam is
3~

divided into three parts. Central part 29 is arranged dis-placeably upon the machine with longitudinal beams 30. Mounted upon the said central part, in such a manner as to pivot about axes running in -the direction of travel 9, in a vertical plane, are booms 31 which are supported on the ground by wheels not sho~n in Figures 1 and 2.
Mounted in such a manner as to pivot in a vertical plane upon transverse beam 27 are colters 32. Outlet apertures 23 of pipelines 24' and 24", connected to front in~ector rows 13' and 13", terminate in inlet connections 33 to colters 32.
In this way, the seed located in storage tanks 1 and 2 is accurately metered by metering elemen ts 11, through pipelines 12 ,12", 24 ,24", into the seed slots produced by colters 32.
Located behind transverse beam 27 is a rail 34 secured detachably thereto. Outlet apertures 23 of pipelines 24"', connected to injector row 13 "' arranged above wheels 6 run past colters 32, arranged in transverse rows to rail 34.
Located in front of outlet apertures 23 from pipelines 24"
are baffle plates 35 which spread the material blown out of 20 the said apertures widely over the surface of the ground.
The micro granular fertilizer from storage tanX 3, thus distributed over the surface of the ground, ensures a good supply of nutrient for the seed placed in the ground~
In order to make the turn at the end of the field, central part 29 of transverse beam 27~ with }~oorns 31, is pivoted upwardly by means of a known hydraulic cylinder -omitted from the drawing for the sake of clarity and connected to the hydraulic sys-tem of the tractor, thus raising colters 32 above the ground. For transportation purposes, booms 31 30 are also pivoted into a vertical position by means o:E hydraulic cylinders, in a manner known per se and there~ore not shown, so that the overall width of the machine does not exceed the permissible limit for agricultural machines traveling along puhlic roads and highways In vrder to determine the amount of seed and fertilizer to be spread be:Eore cultivation, turn off troughs 36 are adapted to be inserted laterally between injector rows 13 ,13",13"' and metering elements 11, through openings in lateral parts 4~
The example of embodiment illustrated in Figure 3 di~fers from the machine according to Figure 1 mainly only in the different design of -transverse beam and colters, and by the presence of an additional storage tan~ for fertilizer This machine is designed Eor the "no-till-drill" method.
Storage tank 37 for fertilizer is arranged between storage tanks 1 and 2 for seed. In this machine, fertilizer is fed through metering elements 38 arranged under outflow apertures 10 from storage tank 37, through guide pipe 39, to inlet hoppers 17 to injector rows 13' and L3".
At the rear of the machine, transverse beam 40 is mounted in such a man:ner as to pivot, in a vertical plane, about an axis 28 located a~ a distance from the said beam and running at right angles to the direction of travel 9.
Transverse beam 40 is divided into two parts. Located on longitudinal beam 41, adapted to move in a vertical plane on the machine, are booms 42 adapted to pivot about axes running in the direction of travel, the said booms being supported on ground 7 by wheels 43~
Arranged upon booms 42, in two transverse rows one behind the other and adapted to move in a vertical plane on parallogram linkayes 46, are "no-Till-Drill" shares 44 with pressure rollers 45. Pi.pelines 24 and 24", connected to front injector rows 13' and 13", conduct the mixture o~ seed and fertili7~er to outlet apertures 23 from these pipes terrninating at the "no-till-drill" shares; whence t~e mixture _ g _ 3~i is deposited in the seed slots produced by shares 44^ Pipe-lines 24"', connected to injector row 13"` arranged above wheels 6, have their outflow ends 23 located behind l'no-till-drill" shares 44 associated with individual pipelines 24' and 24"', above the seed slots or furrows produced by fhe shares.
In this way, high percentage nitro~en fertilizer is deposited at a distance from the seed and fertilizer mixture, upon a small layer of earth.
In order to mal~e the turn at the end of the field, longitudinal beam 41 of transverse beam 40, with booms ~2, is pivoted upwardly with the aid of a hydraulic cylinder, not shown, so that shares 44 are at a distance above the surface of the ground. For transportation, booms 42 are also pivoted, by means of hydraulic cylinders, into position 42' indicated by dotted lines~
In order to determine the amount of feed and fertilizer to be spread before the field is cultivated, turn-off troughs 36 are adapted to be inserted laterally between in~ector rows 13', 13" and 13"' and meteriny elements 11, through openings in lateral parts 4. In this example of embodiment, trou~hs 36 are also adapted to be moved3 aEter the turn off operation, to an inoperative position 36' indicated by the dotted line. In this position, parts of the said trouyhs serve as guide surfaces for the materials de7ivered by metering elements 11 to injector rows 13', 13" and 13"'.
