Section of the jacket-shaped Rotatione-Axlalfördervorriohtung take in. The main belts can also be used alone, without drums, form a shell-shaped rotary axial conveyor.

The present innovation is based on this stage of development with additions and details. This is intended to be the centrifugal method can be made applicable to the various requirements in an extremely simple, lighter and smaller design.

The examples at hand are for light tractor attachments. or a trailer-mounted combiner with an infeed close to the ground on the mower or pick-up table.

With the innovation, any optional combinability is possible of core and jacket-shaped rotary axial conveying devices Subject of the invention. The combinability is necessary for the options in construction, as well as for the option of installing additional elements on the machine. The functions of the nuclear devices should be added to the jacket-shaped devices or vice versa be applicable. In practice, the combinability refers to the fact that a core-shaped device in which the Dresohgut is taken around the outside, a jacket-shaped Vorriohtungselement is assigned. The shell-shaped element runs outside of the threshing rotation. This jacket-shaped element can be a feed, conveying and sole carrier drum at the same time his or a conveyor belt or sieve belt, or it becomes a conveyor roller also used as a grain solution or grain selection roller. The combinability also relates to the fact that in the center of a rotational space a jacket-shaped Device optionally a core-shaped device, e.g. for the heaviest grain solutions or for cutting straw, built-in will. In the exemplary embodiments, the devices are partially combined for an assumed practical purpose. The device elements of the one compilation can possibly also be used for another combination.

coverings Forward or sole support tools provided. To the necessary Abetreifung dee Dreeohgutee from the drums and special wipers are proposed.

Another development goal is being pursued with the innovation. The intake width should be as large as the mowing width used. For large provisioning widths and in the case of the previous Sohrägwalz-Botatlona ^ axial conveyance, several drums, which are divided in the alignment, are required. Although the axial conveying is easy, the aim is to also install aohaparallel drums. For this reason, the axial conveying with screw conveyors, as well as with eohräg mounted free-running or driven tine levers, as well as with Axialabweiaexn and rotating and preferably axially conveying tools is provided. The drum roll * and can then be stored like axes aohsparallel. Large draw-in widths are thus possible. The greater effort required for axial deflectors or screw conveyors can be compensated for by the structural advantages.

A grain precipitation process is used in conjunction with the centrifugal process applied with cyclone wind. In order to refine the grain excretion, two of the centrifugal processes are used various grain cereal deeding procedures based on. The grain ejection process are associated with the use of sieve belts and grain harvesting rollers.

In addition to the stationary screen baskets, circulating screen belts 3 and grain selection rollers 4 are provided for the separation of grains, Pig. 7, 8, 9, 10 and 19 * The sieve belts 3 and readout rollers 4 and for the rotary conveyance at the same time shell-shaped conveying elements. The screen belts 3 are therefore nooh referred to in the centrifugal method as a jacket-shaped device 2β or 2g or 2h. For this purpose, the grain selection whales are also referred to as a jacket-shaped device 2f.

For the grain production, the innovation pursues the development goal, the grain fine screening directly with the grain solution to combine in one device.

The previously used large-sized screen stage surface chiller, Short straw and grain grating, and efficiency from the unfavorable factor of the initial acceleration due to gravity very low limited. With these screening stages of the common combine harvesters, the short straw and grain screen returns reclaimed in a disadvantageous endless concentricity to the threshing device. Impurities get into the repeated rotation with grain-like density and in particular the green waste that was not eliminated by the wind cleaning system can be, which are crushed in rotation until they are mixed with the grain, through the grain sieve the only one Find a way out of the threshing box, as far as it is not on overflowing sieve areas with grain loss «!

For this reason, a finite predeterminable value for the course of the material to be sieved is possible Korn-Hachlösungs- and Ausoheidungsweg from so much

909822/0586

Rotations are required in which, after sufficient grain dissolution and separation, the sieve returns with the Course and Langetroh is requested together from the device. The many sieve stages used so far should be up to pass over to the last grain sieve by inserting a grain sieve with sufficient sieve reserve the centrifugal force of the straw Sieves off demisohed, externally rotating, specifically grain-like mass. The previously used initial Pall acceleration should be with a Rotary screening speed that can be increased up to the permissible limit or a high number of sieve stops / ßec rounded can be.

These tasks are to be solved with the execution examples will.

With the sieve belt 3 or the grain selection scales 4, the first and last grain screening with the last narrow grain mesh world directly with the grain solution device in connection brought. The threshed material drawn into the device after the centrifugal process is carried out within everyone Circulation, of the many rotations, each time on the grain separation device or on the sieve belt 3 or discharge roller 4 for the material to be sieved. The sieve belt 3, for example, sieves with the last narrow one Masohen wide off the kernel material that was premixed by the cyclone wind. The screenings are returned together with the threshing rotation further exposed to the granule solution and following a finite, predeterminable granule dissolution and excretion pathway conveyed out with the short and long straw by contract 23.

The solution to this problem is further improved in the innovation by separating the straw maize from the outside rotating sohwere grain-containing good opposite the centripetal pushed straw can be promoted with a smaller axial slope in the direction of the Auetrag 23. The axial deflectors are for this purpose 33 provided on the Kürnerausscheidungsmantel.

A method sum Eliminating τοη grains from sieved material is added that is in it consists that the grains located on the centrifugal path on a revolving endless conveyor and sieve belt 3, Fig. 7, 6, 10 and 19t thrown on the incoming guide roller 6 and are partially screened off during the frictional closure, of which the through-leaking material in the area of the sieve belt deflection 7 at the deflection angle of about 90 to 270 ° ins The inside of the sieve belt is thrown into a bread roll and Auetragrinne 14. On the other hand, the partially screened material to the draining off Deflection roller θ is promoted, where it is thrown into the rotation space 21 and again after an axial deflection at the incoming deflection roller 6 meets the sieve belt 3, and the cycle is repeated until the Dreeohgut or the screenings return has axially migrated through the device and is pushed out of the screen belt 3 and the rotation space 21 by the load 23.

The Slebbandeinlenkachse 7, Flg. 7, comes with some free running Guide rollers 7a, Fig. Β, aims. The rollers 7 a are on holders 61 from or from an axial deflector 33 attached here. The sieve belt 3 runs over tread strips 60 the pulleys or guide rollers of axes 6, 7 and Θ, and 62. The outer receding belt part runs over the Umlenkaohee 62 with side guide rollers 62a. The incoming deflection axle 6 can also be provided with a roller with a rubber coating. The purpose of the lateral guide rollers 62a is to provide lateral guidance of the cross atarren sieve belt 3. You will run tires 60 inside kept free of the inner spray grains by damming so that no grains are crushed under the rollers. Between the housing 41 and the returning screen belt 3 flows

a blower wind 29 past the deflecting roller 8 as it rolls off in the Rotatlon room 21. The sieve belt 3 is at this point blown off. The blower wind 29 can also be partly guided through the sieve belt 3 into the rotation space 21. The fan wind 29 assumes the cyclone flow course in the rotation space 21.

The same task that is set for the sieve belt 3 is transferred to the grain selection rollers 4, FIGS. 7 and 9. the The composition of the sieve belt 3 and grain harvesting rollers 4 is of no practical importance.

The previously used Sohleuderverfahren is a method for Separation of grains aue Dresoh- or sieve material added, which consists in that located on the centrifugal path Grains on a rotating Ford and grain selection roller 4, Fig. 7 and 9 »are thrown, with the Dresoh- or screenings in the on the selection roller surface remaining coarse material and the fine material penetrating into the Auelee roller separates, whereupon during the rotation that on the Auelee roller remaining coarse material within 90 ° in the flight tangent and with the help of funding, e.g. high pressure blower wind 29, is thrown from the roller surface, whereas the fine material that has penetrated into the Auelesewalze only under its centrifugal force about 45 ° later, after passing a separating device 65, thrown out of the discharge roller 4, and is collected separately in a collecting and collecting channel 14 in the housing 20.

The grain reading rollers 4 are preferably made of plastic flah boret discs 66, fl. 9 »composed. The flat bristle disks 66 alnd eo composed that on the Auslesewalsen surface 4 each individual flat bristle is placed across to the neighboring flaoh bristle. The surface of the grain selection roller 4 is thus impenetrable for pieces of straw, while grains of different sizes are also thrown into the air can and calibrate between the flaoh bristles, delaying for a moment.

The blower wind 29, which blows off the grain discharge rollers 4, flows into the rotation space 21 as a cyclone wind. The case

The conveyor or sieve belt 3 t Pig · 10, can be part of a mantle-shaped device 2g the rotation room 21 E.B. approximately Envelop at 90 °. An infeed conveyor and sole carrier drum 2a envelops a further 90 °. The rest of the shell covers a jacket housing 45 from. They axial conveyance cause axial deflectors 33 within the jacket housing 45 and a cyclone blower wind. The blower wind 29 is blown into the rotation space 21 for the cyclonic flow, with which at the same time the sieve belt 3 within the blower wind distributor housing 41, in particular on the Umlenkaohse 8 is blown off.

The Dreeoh- bsw. Sieve rotation in space 21, Fig. 10, can when using a reverse throwing direction nooh above, without drum 2a, brewed by the conveyor or sieve belt 3 alone will. This method can be used for bulk or short or chopped Threshed or sieved material can be used. The rotating goods is for this purpose under the casing 45 with axial deflectors 33 hurled and supported rom cyclone wind circulated.

In FIGS. 12 to 22, combined core and jacket-shaped devices are shown in detail.

In the case of the combined core-shaped device 1 and shell-shaped Device 2, Fig. 12, the core-shaped device 1 differs from the previous ones in that the Rotationswlcklung 21 around a single drum 1 is made. One possibility is thus cited, such as the axial conveyance, if necessary with axial deflectors 33 on the 270 ° comprehensive KOrnerauBBCheidungsmantel 25 and at the core-shaped device 1 can be brought about. The threshed material is between the Axial deflectors 33 on the core 1 and on the jacket 25 as a straw jacket parts pushed through, partially pulled through and rejected axially. The device can be suitable for windable threshed material in which a high skin friction is appropriate. the Single drum 1 is about 90 to 180 ° from the Axialabweieer- and drum wiper device 70 encased. The axial deflectors 33 on the core 1 and cladding 25 are closed at the front end

Drum wiper tines 34 are formed. Di drums 1 and 2 also consist of the pipe aohae 50 and the pairs of club plates 51. The grain collecting housing 20 encloses the external devices above the feeder housing 44.

The rotation space 21 with a drum 1 in the core, Pig. 12, opens axially in the cutting outlet 15, Fig. 14. A circular knife separates the rotation space 21 baw. the helically thermosetting straw from the overall rotating, axially running straw jacket 21 and continuously cuts a chip in the width of the axial slope rom the straw. The discharge blower wind 30 takes the separated straw behind the discharge partition 16 into the discharge discharge line 46. The circular knife 17 rotates with the intake, conveyor and beater drum 2. The circular knife 17 rolls on the drum 1 at an Oegeschneide. The shaft of the drum 1 can also be the blower shaft 71. On the grain collecting housing 20, the sonideatray jacket 47 is axially connected. The axial deflector and drum scraper device 70 is connected to the son discharge 15 and protrudes from the core-shaped device to the rear end face. The tube axis 50 of the drum 1 with the scraper device 70 in the cutting discharge 15 is also a continuation of the device 1.

In the case of the combined core-shaped door direction 1 and shell-shaped Device 2, Pig. 15, the core-shaped device 1 differs from the previous ones in that the Axial conveying with a sOhneller revolving corner drum 1b with son corner wing 75 is intended. The tightly fitting wiper rail 32 each on the roller 1a of the core-shaped device and roller 2a of the shell-shaped device directs the threshed crop into circulation around the core-shaped device on which the crop is wound around the outside. The faster rotating screw drum 1b conveys the rotating straw jacket axially. The rotation promotion is based on the roller pressure between device 1 and 2 with long wrap-around Dresohgut. From the move-in intermediate

909822/0586 ^ original

conveying 12 away, the crop is jerked to the rotational speed the rollers 1a and 2a accelerated. The circumference in the rotation space 21 is as narrow as for winding possible, whereas the Wiokeldlcke is intended to be eo β tar lc ale possible. For this purpose, the roller 2a is given a corresponding contact pressure elastic wide Apparently 76 and appropriately subdivided several times in width, e.g. 22 and 26. The rotational space 21, around the around the core-shaped device 1, the grain exudation jacket envelops 25 one, the outside again of a grain collector 20 is included. The grain clearance in the housing 20 is provided with blower wind. The jacket-like rotation effect can be reinforced with another Waive 2b.

With the appropriate wrapping properties of the threshed material, this method enables the grain to loosen smoothly during the rolling movement of the Dresohgutmantels between the roller 1a and 2a or 2b. The skin friction is sustained as far as possible a smooth and wide screen basket 25 is reduced.

The previously used centrifugal process is a process sum The loosening of grains from the raw material is added, which consists in the fact that the threshed material casing set in circulation in the rotation space 21 from the core 1 and shell 2 passes through conveying and grain loosening rollers that are elastically pressed against one another. the Rollers 1a and 2a or 2b can be provided with a cylindrical rubber coating for the simplest application. Or the The roller surface is provided with ring or wedge profiles 77, FIG. 17. These profiles interlock and also solve a radial grain loosening effect for the rolling pressure. The respective Wiper rail 32 corresponds to the profiles customized.

The rotation room 21, Pig. 15 _f with a roller 1a and a son corner drum 1b in the core, opens with the end of the screen basket 25, the Schneokenflügel 75 and the roller 1a with scraper bar 32, in the cutting unit 15 »Fig. 18. A circular knife 17 on the roller axis 2a rolls on the Roller 1 a and, opposite roller 1 a, separates the straw which is axially rotating through the rotation space 21 from the overall rotating straw jacket 21. The discharge blower wind 30 takes the separated straw

The core-shaped device 1 is taken from the device in FIG. The roller 1a let a wiper rail 32 is assigned. The snail drum 1b has screw blades 75. The drum 1a forms the opposite of the screen belt 3 or jacket-shaped device 2h Einlenkachee 7. The planned thick straw wrapping in the rotation room 21 adapts the main belt 3. For this purpose, the sieve belt deflection shaft 62 resiliently tensioned 76 the sieve belt 3. The deflection axes 6 and 8 are immutable. Possibly the incoming sieve belt part can be in the area of the front deflection axis 8 all feed belts can be used. The sieve belt 3 separates the grains according to the grain separation process the rotating threshed crop in space 21. The collecting and discharge chute 14 is e.g. Conveyor fan wind cleared. The Uantel housing 45 is flap-like mounted 78 and can resiliently change the width of the rotation space 21 radially.

As a cutting discharge 15 for the device of FIG. 19, the cutting discharge in FIG. 18 is used. The circular knife 17, Fig. 20, is stored separately on a pin and rolls off the roller 1a.

Both the combined core-shaped device 1 and shell-shaped Device 2, Flg. 21, eich distinguishes the core-shaped device 1 from the previously used ones in that on the single drum 1 separate Axialfördervorriohtungen arranged are. The drum 1 takes on Dresohgut for winding over the entire circumference. Due to the elastic conveyor roller pressure between the intake, conveyor and grain loosening roller 2a and the intermediate conveyor roller 12, the rotating material is

sucked The wiper rail 32 is assigned to the orphan 2a. Opposite the drum 1, the rotated material sucked in is reduced to the rotational speed by the resilient contact pressure 76 of the orphan 2a accelerated. In the case of long Dresohgut that can be wiokable An orphan 2a in the dumbbell will be enough to complete the rotational winding in barely 21. Pine another orphan 2b may be attached. The screen basket 25 can flap-like 76 at dit Wioklungsdicke be resiliently adjusted. Sealing clip parts 79 are attached to the strainer basket flaps 25 Bind. In the grain collector housing 20 is the excretion from the conveying fan wind cleared across. PUr the induction housing 44 and the entire Sieve basket 25 is provided with a special slidable coating.

The axial conveyance on the drum 1, Pig. 21, is carried out with a screw conveyor 80. Instead of the screw conveyor 60 can also 2.B. reciprocating gate valves or chain conveyors be built into the drum surface. The screw conveyors 80 form with the interrupted drum surface, consisting of axially extending driver strips 61, the drum surface 1. The conveyor teeth mounted on the drum face 80 will be s.B. with friction wheels on a center, on the Drum axis 1 stationary or slower rotating drive wheel, due to its own rotation with drum 1 faster than the rotating drum speed is driven, the screw conveyors 80 axially at the same time during the rotating drum promote to discharge 23.

In the discharge 23 in the device of FIG. 21 there is a cutting discharge 15 with circular knife.17, as required in the device of FIGS. 12 and 14.

Figures 23 and 24 show a single core-shaped device with a one-sided drum 1, on which separate axial conveyors the rotating material during the rotation convey axially to the discharge. The handy, axially rotating tine discs 85, FIGS. 23 and 24, protrude from the drum case 1 and remove the threshed crop from the intake 22 and intermediate conveyor 12, without Walsenpreasung in the rotation space 21 with around, whereby the grains through the screen basket 25 in the grain collecting housing 20 are thrown out. That Grain-chaff-course straw mixture in the collecting housing 20 can with

909822/0586

Blower wind must be cleared transversely. The toothed disks 85 are, for example, fitted with four strong steel teeth n6 . The tine disks 85 are set in the direction of rotation to the discharge 23 by the rotating drum chain 1 on a stationary or slower rotating axle 87 by means of drive sockets 88 on the axle 87, which are in connection with son corner gears 89 on the tine disc lugs 90. While the tine disks 85 rotate with the drum case rotation 1 in the rotation space 21 old, e.g. 20 m / eec, they simultaneously convey at e.g. 1 m / sec in the direction of the discharge 23 stored on several bearings 92. At the discharge 23, a cutting discharge 15 with a circular knife 17 is again required, as FIG. 14 shows.

The devices of FIGS. 1 to 24 can also be used separately without the actual purpose of a grain solution a special grain solution device.

The devices of FIGS. 1 to 10 can also be used for special axial bale wrapping or axial roll bale pressing be used. To do this, the bale pieces would have to be cut down from the axially conveyed straw roll. Or the Roll pressing with axial conveyance becomes transverse gathering behind Pickups applied to balers or choppers or conveyors. Or the drums become the winder Equipped with knives for special shredding work.

The devices of FIGS. 12 to 24 can also be used as a new type for the special axial winding or axial roll cutting work continuously cutting choppers are used.

Finally, the centrifugal process can also be used with the an eich known tangential straw bale winding or bale roll pressing are provided, in which the rolled up Straw bales can be tangentially weighed out of the wrapping device again during intermittent operation. the According to the invention, the ball rolling device would have to consist of a KöraerauBScheidungsvorriohtung exist to which grain loosening tools can optionally be assigned. The finished rolled bale of straw would have to be carried out according to the invention before the tangential ejection known to us a "from the feeding and discharging" run continuously. 909822/058% ad ORIGINAL
