 traffic-on public roads is not possible) because according to the road code it is / admits for towed devices that a total vehicle width of 2.5 m.

   In addition, because of the large lateral overhang of this chopper .. one needs for specific work a support and exploration wheel located externally on the chopper.



   The object of the invention is to provide a mounted chopper-gatherer which is disposed laterally next to the tractor, such that the coupling yoke of the tractor remains accessible for the attachment of the carriages, while with however, the total width of the tractor and the forage harvester of 2.5 m is not exceeded.



   This problem is solved according to the invention thanks to the fact that the receiving device and the chopping device with the feed, pressing and cutting members form a small elongated construction unit, directed along the longitudinal axis of the tractor. ,; that the receiving device and the chopping device have approximately the same width and are arranged laterally next to the rear wheel of the tractor.



   According to another embodiment of the invention, the receiving device is an in-line mower, such a novel chopper is suitable in particular for chopping corn and given that the in-line mower preceding the chopping device is not does not exceed the permissible total width of the vehicle either, circulation even on public roads is possible without any dismantling.



   According to a preferred form of the invention, the mower can be removed, instead of the in-line mower * it is therefore possible to mount a receiving device made in another way for other agricultural work.



   In order to be able to provide the ramasocuse-bachouse according to the invention also with a collecting device placed before the chopping device and without a cantilever beyond the latter,

  <Desc / Clms Page number 4>

 for certain agricultural work, the receiving device arranged lying in the working position can be raised and immobilized in the transport position around an axis situated in the direction of travel.



   For driving on public roads, such a cantilevered device is raised and the tractor and the chopper no longer occupy more than the total admissible width.



   For this purpose, according to another variant of the invention the axis is disposed on the side directed towards the tractor of the chopping device.



   Preferably, the receiving device consists of a receiving drum and a transverse conveyor screw and its drive is effected by means of an articulated shaft from a shaft of the chopping device.



   In order to exclude damage or deformation of the receiving device in the raised position, according to another variant of the invention, the drive of the receiving drum and of the transverse conveyor screw is put out of action automatically during the lifting by pivoting to the transport position thanks to a coupling.



   In order to obtain a simple but stable constructive form for the chopping device with in-line mower, according to another variant of the invention, the various members of the in-line mower and of the chopping part between two are arranged. side walls each consisting of a unit, which are interconnected at a corresponding spacing. approximately to the width of the drum and of the other members and which jointly form a frame or self-supporting casing of the forage harvester. In this way, a special frame becomes superfluous as a result. as input for the individual parts of the forage harvester.

   It is no longer necessary to provide that two side walls of suitable shape which., According to a preferred characteristic of the invention, are connected to each other by bottom plates which do not meet in the vicinity !.

  <Desc / Clms Page number 5>

 mower stroke in line and through a partial section around the drum shaft, connected to the cutting knife, as well as by a cross member. According to another characteristic of the invention, recesses are provided in the side walls for supporting or guiding the individual members of the chopper pick-up.

   As a result, bearing blocks, mounting plates, and other special components, such as are required for forage harvesters with known special support frames, become superfluous, contributing to a reduction in additional weight. - additional and therefore to a lowering of the cost price of the machine.!
If the machine is to be realized as a mounted forage harvester, the cross member connecting the two side walls can be extended in a simple way in a boom or assembly stand for the side mounting of the forage harvester on a tractor. or a trailer. Obviously, it is also possible to make the pick-up.

        chopper with the construction method according to the invention as a towed machine, when the cross member is produced as an axle for the arrangement of the wheels.



   In order to offer a simple mounting device for the lateral mounting of the harvesting device on the tractor, with which the tractor coupling yoke remains accessible for the attachment of carriages or notes, but which however, thanks to its realization simple and at favorable equal ratios in terms of force, is of markedly reduced weight, in another embodiment of the invention, a cross member extending from the frame of the machine to the - beyond the middle of the tractor, and carrying the coupling studs for the lower levers, two struts directed upwards in the direction of the tractor up to the vicinity of its coupling yoke,

   struts on which is freely pivoted a bracket which has a support eyelet which can be connected to the connection point for the upper lever on the tractor,
Following another character @@@ @

   ja @ bec de iorge arranged in the travorse have the shape of an arch or an angle, of which. the branches directed towards the cross member extend in an approximately horizontal direction and the branches of which directed towards the connection point on the tractor extend in an approximately vertical direction.



   In this way, the whole of the space or the pivoting zone around the coupling yoke is perfectly free behind the tractor, so that even when driving in small radius curves, a collision between the towing drawbar of the trailer or the cart and parts of the harvesting machine cannot be made.



   In order to be able to use the device mounted on different implementations and dimensions of tractor, several holes and bores have been provided on the angular struts fixed to the cross member, in the branches directed towards the connection point. and in addition the legs of the etrior also have several holes or bores. In this way, the connection of the device carried with the connection point for the upper lever on the tractor can be established simply for different dimensions and implementations of the tractor.



   In order to be able also to mount on tractors which are equipped with a standardized three-point linkage, a forage harvester which extends in working position from the coupling points for the connection of the three levers to the before, following another embodiment of the invention and when using the normal lower levers and the standard connection point for the upper lever on the tractor, a leg has been provided. be of force constituting the third connection between the mounted device and the tractor, in such a way that the axes of the lower levers and of the strut in the lowered position intersect at a point, which is located behind the articulation points for the lower levers.

   The point of intersection with the lower levers of the strut, which in this case replaces the upper lever constitutes

  <Desc / Clms Page number 7>

 then kills the ideal guidance point around which the switchgear moves during the lifting movement. Since this point is behind the lower hinge points on the equipment side and according to a further feature of the invention it can be moved a certain distance from the hinge points, it is possible to raise the hinge point. The device practically parallel to the ground or, if necessary, with the tip extending more strongly from the ground.



   In another useful embodiment of the invention, the carried device can be made such that the pick-up; The chopper is detachably connected to the mounting frame, which offers the advantage that it is possible to mount on one and the same mounting device different harvesting devices, which require such mounting. Thus, for example, a chopper can be replaced by a mower or the like.



   In order to facilitate the assembly of the harvester device on the tractor, there are provided on the mounting frame pivoting rest supports on the mounting frame, on which the device can be placed at a favorable height and position. for mounting. Resting devices have also been provided on the harvesting device, in order to facilitate removal of the machine and disassembly as well as assembly on the assembly device.



   Another feature of the invention lies in the fact that a support wheel is provided on the mounting frame which allows the machine to be adjusted with regard to its cutting height from the ground. support offers the advantage for a porto implement that the lower levers of the three-point linkage do not have to be held or adjusted to a determined distance above the ground} by the tractor's lifting device. , the support wheel can also be fixed to the harvesting machine itself,

     In order to realize the mounted device and the drive for a forage harvester working sideways next to the tractor

  <Desc / Clms Page number 8>

 tor so that the forage cutter is located outside the pivoting area of the receiver or trailer hitched to the tractor, without the articulated shaft extending from the tractor PTO shaft to the angular transmission on the assembly frame is placed at an unfavorable or inadmissible angle,

   another embodiment of the invention is characterized by the arrangement of the drive shaft of the harvesting device before the coupling studs and of the connecting shaft end of the articulated shaft on the shaft. angular transmission after the coupling studs for the lower levers of the three-point linkage. r
The principle of the invention, consisting in placing the harvester device with its drive shaft further forward, in order to be able to use the pivoting area necessary for the hooked receiving carriage and to move back the end of the connection shaft more strongly. the articulated shaft on the angular transmission, so that the articulated shaft does not have to make any inadmissible angle, can be implemented in various ways.

   Thus, according to one characteristic of the invention, the transmission shaft leading from the angular transmission to the harvesting machine can be made in two parts, by arranging the power take-off shaft of the shaft. angular transmission with an offset approximately parallel to the drive shaft on the harvesting machine, The connection between the two offset shafts can be made by means of an articulated shaft or by means of a pair of straight toothed wheels .; 'or for example using a chain mechanism.

   The removal of the part lying inside the tractor wheels of the mounting chaste still offers the advantage that the coupling studs for the lower levers can be sufficiently in front of the mounting chas- sis, so that mounting on a quick coupling is also possible, which is not the case with known mounting frames where the coupling studs are tight against or above the cross member.

   With such a transmission, the device

   For the connection of harvesting devices
 EMI10.6
 corsbruction 'and of different dimensions with one and the same mounting and training device, it may be advantageous to produce, according to another characteristic of the invention) the crossmember of the

  <Desc / Clms Page number 11>

   mounting frame carrying the harvesting device with the possibility of telescopic length variation.

   In this way, it is achieved that the harvesting device concerned can be mounted in each case laterally at an optimum distance from the rear wheel of the tractor. Particularly close alignment of the collecting device and the rear wheel of the tractor is advantageous with light tractors because of the unilateral loading of the rear wheels and for heavy tractors with a greater track width so as not to exceed the vehicle width allowed for the tractor and the mounted harvesting device of 2.5 m, according to the highway code.



   In realizing the mounting frame with a variable length cross member, the drive device can most usefully be designed so that the drive shaft leading from the angular transmission to the harvester device is formed by two parts, one end of the shaft being made as a polygonal profile and the end of the other part of the shaft as a bush, so that the profile and the bush together form one part telescopic, which allows variations in the length of the shaft and consequently the connection of the harvesting device at varying distances from the median axis of the tractor,

   
In order to offer a mounting device with which it is possible to mount even on tractors with a low coupling yoke and the corresponding harvesting cart with a low hooking drawbar, a harvesting device working out of the track tractor, on the standardized three-point linkage and to raise it to a sufficient transport height, according to another embodiment of the invention, the mounting easel which can be connected to the three control levers is placed. the three-point linkage above the drawbar of the harvest cart.



   A preferred embodiment of the invention resides in that on a cross member comprising connections for the three-point linkage and receiving an angular transmission and a

  <Desc / Clms Page number 12>

 drive transmission shaft, there is an arm directed preferably obliquely downward and located outside the rear wheel of the tractor, on which are provided drive transmission elements and connection means for the harvesting device,
Thanks to this arrangement,

   the part of the assembly stand behind the tractor in the area of the towing bar of the harvesting cart is so that it is located above the towing bar and is therefore not hampered by the latter in its lifting movement, while the part of the mounting easel serving as 1] connection with the collecting device is located near the ground so that the known current collecting devices can be attached to it without significant modification.



   According to another characteristic of the invention, it is also possible to produce the cross member of the assembly trestle such that it extends rectilinearly beyond the width of the tractor as far as the harvesting device and that it has at this end connection means for the harvesting device.



   On such a cross member, according to another characteristic of the invention, it is possible to provide the coupling points for the arrangement of the mounting trestle in such a way that the latter can be selectively connected at a different distance from the ground. by the three-point linkage of the tractor,
Such an embodiment allows the use of both types of harvesting carts and tractor and in fact it is possible to hook both normal harvesting carts with a straight towing drawbar to the upper coupling yoke as well as harvesting carts with Low attachment to the lower coupling yoke or to the tractor coupling pendulum.



   Since in various tractors the PTO shaft thereof is located in different ways relative to the coupling yoke and because of the mounting of the mounting trestle on the three-point linkage at different heights from the ground and

  <Desc / Clms Page number 13>

 therefore in different positions with respect to the power take-off shaft, different angles are reached for the articulated shaft leading from the power take-off shaft to the angular transmission. In order to avoid possibly too pronounced angles of the articulated shaft,

   according to another characteristic of the invention is associated with the angular transmission connected to the crossmember an intermediate or auxiliary transmission constituted by a pair of straight toothed wheels, which can be connected: selectively to the angular transmission of such so that the connecting shaft end of the articulated / knitted shaft is below. either: above the cross member.



   If the same harvesting device is to be used for loading or filling the two types of harvest trolley, that is to say both those with high hooking as those with low hooking, it is possible to provide on this one. here two superposed fixing means, for the connection with the assembly easel, which make it possible to connect the latter either in a higher position, or in a lower position to the collecting device.



   In order to offer a mounting device for the three-point linkage on the tractor leaving the coupling yoke free of the latter, while greatly increasing the pivoting area for the drawbar of a trolley or a trailer, according to another embodiment of the invention the coupling for the connection of the upper lever is arranged eccentrically, preferably outside the coupling points for the lower levers on the cross member of the chassis. mounting.



   Thanks to the widely eccentric position of the coupling, the space necessary for hooking a trolley around the coupling yoke is completely free, even with a device carried in the lateral direction, in such a way that the ability to maneuver with the tractor and the truck is not hampered in any way, even when turning over and driving in curves of small radius.



   According to a preferred embodiment of the invention

  <Desc / Clms Page number 14>

 tion the @evier epariour presented at its end on the tractor side means for the length adjustment, in order to allow the adjustment of the position necessary for the various works of the @active device and the adaptation to different tractors.

   On various tractors, the painted erticulation on the tractor side for the upper lever and the coupling yoke are located very close to each other, so as to achieve the advantageous in these cases / the eye of support for the link with the tractor, the upper lever with the possibility of swiveling and immobilization.



   In the case of a standard three-point linkage, the two lower levers and the upper lever are so arranged with respect to each other that their axis lines intersect at a point before the rear axle of the tractor. Since the upper lever is shorter than the two lower levers and some three levers considered laterally together form a quadruple trapezoidal articulation, the mounted collecting device is raised more strongly at the rear than at the front, when lifting to the transport position.

   This is correct and even desirable for mounted devices which extend substantially rearward beyond the coupling points for connection to the three levers. Difficulties are encountered, however, when mounting brackets. devices which extend essentially in front of the three coupling points, as is the case, for example, with a mounted forage harvester with in-line mower working sideways next to the tractor. Such a device has with respect to its transverse extent and because of the in-line mower preceding the chopper part, a great constructive length which extends next to the rear wheel of the tractor from the coupling points of the three point linkage, forward.

   If this device were to be mounted on the normal three-point linkage, it would come into contact with the ground at its front end, since it swivels downwards, since the mounted device is positioned obliquely.

  <Desc / Clms Page number 15>

 towards the rear and directed upwards causing the recovery, and according to the degree of the pivoting it would be damaged or even totally destroyed,
In addition, raising the device to the required transport height would absolutely not be possible.



   In order to make the door device according to the invention also usable for the devices described above, the coupling is carried out with a possibility of modification in length according to another characteristic of the invention. By means of the variable length coupling the angle of the upper lever can be adjusted so that the centerlines of the lower levers and the upper lever in the lowered position intersect at a point behind. the articulation points for the lower levers.



   The point of intersection of the upper lever with the lower levers naire then constitutes the imagined guide point, around which the apparatus pivots during the lifting movement. Since this point is behind the lower articulation points on the device side, it is possible to raise the device almost parallel to the salt or if necessary with the point further from the ground.



   In another useful embodiment of the invention the device-side hinge point for the upper lever is made adjustably in a plane perpendicular to the direction of travel and / or in the direction of travel. This offers a possibility . additional adjustment of the carried device, which becomes univeroel and which allows the assembly of more diverse agricultural implements.



   According to a characteristic of the invention, the upper lever can be produced as a U-shaped caliper, the branches of which are articulated on the couplings arranged outside the articulation points on the cross member, This provides a stable realization of the upper lever as required for heavy mounted devices. Finally, according to another feature of the invention, the cross member of the mounting frame may be constituted by

  <Desc / Clms Page number 16>

 two parts which slide one inside the other telescopically. This allows: lateral adjustment of the mounted device relative to the tractor.



  In addition, the cross member can be equipped with a quick coupling which cooperates with coupling elements provided on the device, which has proved to be very advantageous when exchanging different devices carried using the same mounting frame.



   In order to support the front end of a mounted forage harvester in a simple manner, according to another embodiment of the invention, the forage harvester is placed in front of its center of gravity and preferably in the vicinity of the extension of the forage harvester. the rear axle of the tractor, a support wheel rotatable by a hydraulic working cylinder, the pressure side of the lift cylinder of the tractor lifter being connected to the working cylinder on the forage harvester as such so that pressurized oil), the pressure of which is produced by the weight of the raised or spread chopper, can be sent at any time that, one can choose from the lifting cylinder to the working cylinder on the chopper.

   The choice of the moment of transfer of the oil into the working cylinder can be made either by the tractor operator or be determined by an automatic control or blocking device.



   To adjust the upper and lower swivel area of the starter wheel, i.e. the lifting height and cutting height of the chopper, the swivel range of the starter wheel is limited by stops .. at least one of these can be made in an adjustable manner.



   A simple and advantageous solution for the separation or raising of the front end of a harvesting device working next to the tractor can be obtained according to another characteristic of the invention thanks to the fact that the front end of the device is connected. to the lifting linkage for the tractcur mower or the skid of the latter. According to a preferred embodiment

  <Desc / Clms Page number 17>

 Re of the invention, the connecting means between the lifting linkage and the device are adjustable in position ot on length.



  As a result, the device can be connected to various tractors and to different mower designs in a simple manner.



   In order to allow the use of a small-sized drum chopper with a row mower also for several lines, according to another design of the invention, several drum choppers are brought together, each comprising a mower, as well as the feeding, pressing and cutting members for here part of the mower, in a unit constituting a device with several lines,
This gives the advantage that, because each individual device has its own cutting mechanism for each line,

   Therefore a relatively small drum one is assured in all cases of a good quality of chopped straw and the power required is lower compared to known multi-line choppers-choppers, because the chopped product is fed into straight flow as a cutting pad evenly distributed over the cutting drum.



   According to a preferred embodiment of the invention, two identical drum choppers are fixed on a mounting frame which can be connected to the three-point linkage of the tractor and which extends transversely to the direction of travel. Drum choppers can be arranged with. a possibility of movement and immobilization on the assembly frame. By virtue of the possibility of displacement, the advantage is obtained that the apparatus can be adapted to the various line widths encountered in practice.



   The drive of the individual drum choppers takes place via an angular transmission fixed to the mounting frame and a. drive shaft from which drive means extend to the individual drum choppers,

  <Desc / Clms Page number 18>

 
As a two-line machine, the small liter forage harvester is designed as a pure mounted machine.

   In the case, for example, where the lifting capacity of the tractor is not sufficient or when for some other reason it is useful to support the forage harvester in relation to the ground, it can be fixed at the outer end of the mounting frame a support wheel.



   In order to be able to have the forage harvester ready for the feeder! ' in the field and to bring it back to its point of attachment also on public roads, the cross member of the assembly frame, according to another characteristic of the invention, can pivot around a vertical journal and be immobilized by means of a plug, dowel or the like. In this way the forage harvester can be swiveled for transport from the side of the tractor to the middle or behind the tractor, up to the permissible vehicle width for the tracks public.



   For this purpose, the mounting frame can also be made in such a way that the cross member thereof is constituted by a part which can be connected to the three-point linkage of the tractor and another part carrying the drum chopper, these parts being pivotally connected between them and so as to be able to be immobilized. This embodiment offers, in addition to the possibility of swiveling for the transport position, also the advantage that because the carried device consists of a mounting frame itself and a part or part carrying the collecting device. , which can be released from the mounting frame, the mounted device can also be used for other harvesting devices.

   A quick coupling known per se, automatically establishing a rigid connection, can then be used to connect the two cross member parts of the mounting frame.



   According to another feature of the invention, in a two-line apparatus, a drum chopper can be attached to the part of the mounting frame connecting to the three-line linkage.

  <Desc / Clms Page number 19>

 points and the other drum chopper to the swivel part of the mounting frame. This embodiment offers the advantage that the chopper can be used either for one or for two lines.



   The mounting frame connected to the three-point linkage of the tractor is made in such a way that the coupling yoke for the coupling of a trolley or a trailer is completely free even with the machine carried or mounted in place . In order not to interfere with this free space even with the machine made to pivot in the transport position, according to another preferred embodiment of the invention, the external pivoting part of the crossmember can be raised with the drum chopper. which is fixed for transport by pivoting around an axis located in the direction of travel.



   It is obviously also possible to carry out the pick-up; chopper according to the invention as a towed device, in which case, according to another characteristic of the invention, this device is fixed to a cross member supported by wheels.



   This embodiment is particularly useful when it is necessary to have more than two drum choppers next to each other, so that the lifting capacity of the tractor lever is no longer sufficient to raise them. .



   In the context of the present invention, it is also 'possible to fix several identical drum choppers on a support or a beam mounted on the front loader of the tractor, in front of the latter.



   According to another characteristic of the invention for mounting in front of the tractor, several identical drum choppers are attached to a bin articulated on the front coupling yoke of the tractor, a beam from one end of which a stabilizing bar leads. to the tractor rear drawbar.



   The installation of a forage harvester in front of the tractor offers the known advantages that the tractor operator can observe the machine well while working and as it is

 finds, even in the case of several lines, within the limits of the permissible width of the vehicle, no special provision need be made for transport on public roads, In a useful embodiment for the mounting device in front of the tractor, the beam carrying the forage harvester is supported relative to the ground by means of at least one support wheel and can be adjusted and raised using a hydraulic cylinder equipped with a similar mechanism.



   The outlet connections of individual drum choppers can be joined, according to a characteristic of the invention, in an ejection elbow, in order to ensure better flow or better ejection of the chopped product. In order not to interfere with movement or adjustment of the individual chopper assemblies on different line widths, the ejection elbow can be arranged with a possibility of telescopic movement and immobilization on the outlet fittings, or else the ejection elbow can be connected by flexible intermediate pieces to the individual outlet fittings.



   In order to increase the working width of a firebox which can be mounted laterally next to the tractor, without exceeding the total permissible width for the tractor and the forage harvester of 2.5 m during transport, following a Another embodiment of the invention is the forage harvester provided with a width pick-up device, a two-row mower or a second.

 ne and next to the return wheel, a stop is provided at a spacing which is less than the circle described around the center of the return wheel by the tips of the drive members .; when the spring is relaxed. Thanks to this arrangement, the input chains are each held by a spring at the required operating tension.

   In the event of a chain breakage, the spring pushes the return wheel, which in this case simultaneously has the function of a chain tensioning wheel, towards an opposite stop against which the defective chain but which nevertheless continues. to progress under the effect of its inertia, remains hooked and thus cannot in any case reach the chopping device.

   In Figures 1 to 3, there is shown a chopping device 1 with an in-line molding machine 2, which is mounted by means of a frame 3 on the three-point support linkage of a tractor 4. The mounting frame 3 is located in this case in a plane below the coupling yoke 5, so that it is possible to hang directly by its towing drawbar 7 a trolley or a trailer or a trolley 6 behind the tractor 4.



   The chopper device 1 is preferably designed as a drum chopper device of reduced size and it is located with the in-line mower 2 in front of it out of the tractor traffic lane, laterally next to the wheel. behind it, the in-line mower 2 and the feed, pressing and cutting members of the chopper device 1 are mutually tuned in such a way that they can be united in as small a constructive unit as possible, so .'how that one obtains a total width of the chopping device 1 with the mower in line 2 and the tractor 4 of 2.5 m maximum.



     The drive of the chopping device 1 with the in-line mower 2 takes place from the shaft end 8 of the tractor, via an articulated shaft 8a and / an angular transmission 9, which constitutes. with frame 3 a constructive unit.



   The housing of the chopping device 1 with the in-line mower 2 is produced as illustrated in FIG. 4 as a self-supporting frame and it consists essentially of two walls; lateral sides 10,11, identical to each other and shaped in an aymetric manner, which are connected to each other by bottom plates 12,13 and a cylindrical partial section 15 forming the casing of the knife. connected to the knife blade 14 around the drum shaft 16 as well as by a cross member 3. In order to make the representation clearer, FIG. 1 shows the parts belonging to the casing or to the housing. frame of the chopping device with the mower in line in solid lines and the other components in phantom.

   The connection of the side walls 1a, 11 is usefully made

  <Desc / Clms Page number 28>

 by welding so that the parts 10,11, 12,13,15 and 3 form in common a stable drive on all sides and self-supporting intended to support and fix the individual parts of the chopping device with the mower in line. In order to increase the stability of this frame in the transverse direction, two stiffening ribs 19, 18 have been welded to the side walls 1a, 11, on either side, which simultaneously serve to fix the bearings for them. chain wheels of the upper feed chain 20 and the lower feed chain 21 of the in-line mower.

   For the passage of the lower supply chain 21, there are provided in the side walls 10,11 cutouts 22,23.



   In addition, there are provided in the side walls 10, 11 for the supports of the feed or feed chain 24, bores 25, 26 and for the support of the smooth cylinder 27, bores 28. For the cylinder. feeder or introduction 29, which is freely movable against spring pressure and for the pressure roller 30, which is guided approximately tangentially with respect to the cutting drum 31 and which is freely movable in its guide system, recesses 32 and elongated holes 33 are provided in the side walls 10,11.

   The cutting drum 31 is introduced, because of the simple assembly .. from the outside in slots 34 made in the side walls 10, 11 and it is fixed by these bearings to ribs 35 rigidly connected to the side walls 10, 11 and 4 the cross member 17. Behind the cutting drum 31, the outlet channel 36 has been arranged in the usual way.



   Figure 5 shows the self-supporting frame of the chopping device with the in-line mower, as assembled by welding into a set from parts 10,11,12, 13,15 and 3 and stiffening ribs are found on both sides 18,19. The organs of the chopping device and the mower in li-

The crossing ? which is preferably constituted by a tube, simultaneously serves as a housing and a pretension for the drive shaft 37 which leads to a conical transmission, not shown, which is driven from the PTO shaft of the tractor .



   If the chopping device with the in-line mower were to be realized as a mounted device which normally works laterally next to the tractor, the spindle 3 must be calculated with a length such that the connections can be provided for. the three-point linkage of the tractor 4.



   If the chopping device with the in-line mower comprising the chassis according to the invention were to be produced as a towed device, the cross member 3 can be designed in the simplest way, as shown in FIG. 6, as an axle for receiving the wheels 39. Naturally, in this case, it is necessary to have for towing a drawbar leading to the tractor, which can however be produced in any known manner and which has therefore not been shown in detail in the drawing. or
The mounting / mounted device 40 consists of the two lower levers 41,42, the three-point linkage, the mounting frame 3 and a strut 44 extending from the mounting frame to the point of attachment. 43 for the upper lever on the tractor 4.

   The mounting frame 43 is preferably a tubular cross member, at one end of which is arranged the chopping device 1 with the in-line mower 2 and at the other end of which are located the two coupling points 45,46 for connection to the lower levers 41,42. In the vicinity of the coupling points 45,46, two struts 47,48 extending obliquely in the form of an arc upwards and forwards were welded to the crossmember 3. At the upper end of the legs

  <Desc / Clms Page number 30>

   de @oree @ 7.4 is freely pivoted at 40, a U-shaped stirrup constituting the strut 44.

   On the strut 44 is fixed a support eyelet 50, which serves to connect this strut 44 to the point; the attachment 43 on the tractor.



   As it emerges: from: Figure 7, the axis lines 51 of the lower levers 41 and 42 and the axis line 52 of the strut intersect this 44., which passes through the two points of support 43 and 49., / at a point P which is located behind the coupling points 45,46.



   In order to be able to change the position of the point of intersection p, several bores 53 have been provided on the struts 47,48 to support the strut 44. This is also advantageous for the adaptation of the mounting device to different tracts,
The realization of the strut 44 as a caliper offers the advantage that it can be passed around the coupling yoke 5 of the tractor 4, so that the latter is free, even with a device. mounted, for attaching a trolley or trailer 6 using a tow bar 7.



   The attachment or the connection of the collecting device 1,2 with the mounting device can be usefully carried out as shown for example in FIG. 9. In this case, to the collecting device 1,2 is connected a connection piece 54 which has the form of a tubular shell. On the cross member 3 are welded two tabs 55, which are screwed to the tubular shell 54,
To deposit the collecting device, we have arranged on the mounting device of the laying supports 56 and the collecting device 1,2 of the supports or laying supports 57 For the working position, the laying supports 56 and 57 can be raised by pivoting. In addition, if necessary, one can arrange on the mounting device a height adjustable support wheel 58 for adjusting the cutting height of the harvesting device.



  In this case, the laying support 56 arranged in the vicinity of the support wheel 58 can be eliminated.

   The mounting device consists in the embodiment of Figure 10 by a part 60 of a cross member 3 located in the area between the wheels of the tractor and by a part 61 protruding beyond the width of the tractor, at the outer end of which the harvesting device 1.2 is attached.



  The cross member 60 is organically connected to the angular transmission
9, which returns laterally the drive coming from the power take-off shaft 8 of the tractor, via the articulated shaft 8a, towards the harvesting device 1,2, When no particular arrangement is made. is taken, the danger is encountered with a rectilinear cross member 3, as shown for example in FIG. 8 and when driving in a curve, that the front part of the harvesting cart 6 comes to meet the collecting device, reason whereby, according to Fig. 10, the cross member portion 61 and hence the collecting device 1,2 are disposed relative to the cross member portion 60 in parallel and with a forward offset;

  The two cross member parts 60 and 61 are again made as tubes, in which the drive shaft 63 from the angular transmission 62 and the drive shaft 64 leading to the collecting device 1,2 are supported. . The connection of the two shafts 63 and 64 is effected by means of a pair of straight toothed wheels 65, which is arranged in a housing 66, which simultaneously serves for the connection of the sleeper parts 60 and 61. Los rouce Straight teeth 65 can just as easily be replaced by a chain mechanism known per se.

   As can be seen from FIG. 10, the mounting of the collecting device 1,2 on the cross member part 61 and the arrangement of the angular transmission 9 on the cross member part 60 are established in such a way. so that the drive shaft 64 of the harvesting device 1,2 comes to sit in front of the coupling studs 45,46 and the connecting shaft end 67 of the articulated shaft on the angular transmission 9 comes into place. behind the coupling studs 45,46 for the

  <Desc / Clms Page number 32>

 . lower levers 41,42 of the three-point linkage, with an offset of a distance a or b.



   The embodiment according to figure U is for the most part identical to that of figure 10 and is distinguished only by the mode of connection of the two cross member parts 60 and 61 and in fact in this case these two parts are connected between they by a support part 68 overlapping their offset, in which an articulated shaft 69 or a similar member has been supported, which provides the connection between the drive shaft 63 and the drive shaft 64.



   In the embodiment according to Figures 12 and 13, the cross member 3 is again made as a straight tube, but however the coupling studs 45,46 on the cross member 3 are arranged behind its longitudinal central axis, so that the cross member 3 is presented with the harvesting device 1,2 as far forward as possible, that is to say as far as the rear wheels of the tractor allow.

   In order not to cause in this case the articulated shaft 8 a. Driving the power take-off shaft 8 of the tractor to the angular transmission 9 to form angles beyond the admissible range, the angular transmission 9 has been placed on the angular transmission 9. an auxiliary transmission constituted by a pair of straight toothed wheels 70, so that the end of the connecting shaft 67 of the articulated shaft comes to place further back and actually up behind the coupling studs 45,46 so that the articulated shaft 8a takes a less angular position.

   The auxiliary transmission 70 can be removed from the angular transmission 9, so that with tractors 4 having a power take-off shaft 8 placed low, so where the danger of too steep angles of the articulated shaft does not occur. not present, the angular transmission 9 can also be driven directly without an auxiliary transmission 70.



   On the dorsal side of the angular transmission 9, as well as of the auxiliary transmission 70, protrudes from the housing a

   In the embodiment of FIGS. 14 and 15, the drive of the harvesting device 1, 2 takes place again from the PTO shaft of the tractor 4 by means of an articulated shaft 8a which leads to the angular transmission 9 organically connected to the cross member 3. The angular transmission 9 is in this case constituted by a housing 80, in which is supported a pair of bevel wheels 81, 82. One of the bevel wheels, 81, is arranged on a shaft 63 supported in the cross member 3 produced as a hollow beam, this shaft 63 ensuring the transmission of the drive from the angular transmission 9 to the device. harvester 1,2. The other bevel gear 82 is disposed on a shaft 83 supported in the housing.

   In parallel with this shaft 83, another shaft 84 has been supported in the housing 80. The latter is produced at its ends as a wedge profile, one of the ends of which 85 serves to connect the articulated shaft 8a.

  <Desc / Clms Page number 34>

 leading to the tractor's drillshaft pattix and the other end 86 to the connection and an articulated shaft 72 leading: to the harvest cart 6.

   On the two shafts 83.84 are placed straight toothed wheels 87.88 which jointly form an integrated transmission. mediator
From the straight toothed wheels 87,88, the driving rotation of the articulated shaft 8a is transmitted to the conical transmission 81,82. If the straight gears 87.88 have the same number of times, only the direction of rotation of the conical transmission, 81.82 is changed by the intermediate transmission 87.88 per ratio. port to a direct drive.

   It is, however, also possible, as shown in Fig. 15, to realize the spur gears 87,88 with different numbers of teeth and furthermore as gear change wheels.



   By exchanging or replacing the gearshift gears 87,88, it is possible to modify the driving speed of the harvesting device 1,2. For this purpose it is sufficient simply to remove a cover 89 of the transmission housing 80, which xend - accessible the gearshift gears 87.88.



   On the shaft 83, there is provided a movable claw 90, which forms with the right toothed wheel 88 or 87 involved, threaded on the shaft 83, a claw coupling. The straight toothed wheels 87 88 are provided for this purpose with drive chins known per se and cooperating with the claw 90. The adjustment provided for each of the straight toothed wheels 87,88 on the shafts 83,84 has a different diameter while las straight toothed wheels, in order to ensure an exchange, present 10 same bore.

   In order to compensate for the adjustment diameter of the shafts .. a bush 91 has therefore been provided on the shaft 83. The claw coupling 90 is controlled in the usual way using a control lever 92 disposed on the transmission housing 80 and which can be usefully made so that it can be reached from the tractor seat.

   When

  <Desc / Clms Page number 35>

 when the coupling 90, as shown in FIG. 15 is engaged, the harvesting cart 6 and the harvesting device 1,2 are driven simultaneously, With the disengaged coupling the harvesting device 1,2 is stopped, which is advantageous when unloading, from the cart in the farmyard,
As can be seen from Figure 14, the cross member 3 is in this case made in two parts 93 and 93 ', the part 93' being telescopically threaded over the part 93.

   This telescopic link allows in a simple way a lateral displacement of the harvesting device 1, 2 with respect to the tractor 4 and consequently the adaptation of various harvesting devices to different tractors and tractor track widths. The connection of the two crosspiece parts 93, 93 'can be effected with known means, for example by force-bonding clamps or else form-bonding clamps. The connection can also be made by clamping in such a way that the two cross-piece parts 93,93 'can rotate with respect to each other, which gives an additional adjustment possibility. for harvester 1.



   With the realization of a crosspiece 3 which can be modified; telescopically in length, the transmission shaft 63 leading from the angular transmission 9 to the harvesting device 1, 2 with the possibility of modification in length, from two parts 63 and 63 ', must also be produced. In this case, the connecting end of the shaft 63 supported in the cross member 3 can be made partially in a prismatic shape, for example square or hexagonal, and be threaded into a suitable socket 63 '.

   The prism and the bush form in a manner known per se a telescopic part which allows modifications of the length of the shafts 63.63 'and consequently the connection of the collecting device 1,2 at different distances from the median axis of the shaft. tractor.



   The mounting device in the embodiment according to Figures 16 and 17 consists of a mounting trestle which has a cross member 3 located in the area of the width.

  <Desc / Clms Page number 36>

 of the tractor and an arm 94 which is connected to it, which is directed obliquely downwards and which is arranged outside the rear wheel of the tractor, arm on which is fixed, that by means of a flange connection 95 or by other coupling means, the harvesting device
1,2, for example a forage harvester,
To the cross member 3 is again organically connected an angular transmission 9 which laterally returns the drive from the tractor PTO shaft to the harvesting device 1,2.

   From the power take-off shaft 1 to the angular transmission 9 extends an articulated shaft 8a known per se and in the cross member 3, which is produced as a hollow beam, a transmission shaft has been supported drive 63 which transmits the drive by means of a spade mechanism 95 disposed in the arm 94, also constituted by a hollow section or by means similar to the collecting device 1,2. Sure. the crossmember 3 is also provided for the connection to the lower levers 41,42 of the three-point linkage, coupling pins 45,46 and for the connection with the upper lever 96 a vertical post 97.



   The rear part sketched in Figures 16 and 17 of a tractor 4 has a coupling yoke 98 in the low position, to which is attached a harvesting cart 6 by means of a towing bar 99 of special construction for hooking up. in low position. The arm 94 has a length such that when the harvesting device 1,2 fixed to its lower end is in the working position, therefore on the ground, the cross member 3 is located above the towing bar 99 of the trolley. harvest 6, Since the drawbar 99 lies relatively low to the ground, the mounting device with the harvesting device 1,2 can still be raised within the limits of the lifting stroke of the tractor lifter to a further transport height sufficient.

   In the embodiment of the mounting device according to Figures 18 and 19, the

  <Desc / Clms Page number 37>

 assembly easel has a crossbar 3 which extends in a rectilinear fashion beyond the already width of the tractor as far as the harvesting device 1, 2, which is connected to the crossbar 3 by means of fixing means 100 appropriate. The fixing means 100 eont provided on the harvesting device 1,2 at a height such that in the working position of the device, the cross member 3 is located above the drawbar 99 of the harvesting cart 6.



   On the cross member 3, it is possible to provide in addition to the coupling studs 45,46, also a pair of other coupling studs 101,102 for connection to the lower levers and on the upright 97, at a distance suitable, additional bores 103 for connection with the upper lever 96. Thereby one has the possibility of connecting the mounting bridge to the three-point linkage at different height positions, so that both the coupling of a trolley or a trailer with a towing drawbar 99 is possible with the lower hitching yoke 98 as of a carriage with a towing drawbar 7 with. the upper coupling yoke 5.

   In the first case, the crossmember 3 is placed above the towing drawbar 99, while, in the second case, as shown in mixed milking in Figures 18 and 19, it is located in a manner known as towing drawbar 7. On the harvesting device 1,2, we naturally have;

          In this case also need additional fixing means 104, when these must be used for the two types of harvester trolley,
With the mounting device according to Figures 18 and 19, the angular transmission 9 is also associated with an auxiliary transmission 105, consisting of a pair of straight toothed wheels, which can be connected normally to the angular transmission 9. as in the case of figures 16 and 17 or with a pivot of 180, 1 as indicated in phantom in figure 19.

   In the first case, the end of the connecting shaft 106 for the articulated shaft is placed

  <Desc / Clms Page number 38>

 cer under the cross member 3 and in the second case above this one.



  In this way, one avoids too rough angles of the articulated shaft Sa in the two mounting positions of the bridge,
Figures 20 to 29 show still other variants of the mounting device. The cross member 3 for mounting the forage harvester 1, 2 is again made as a hollow beam and has two coupling pins 40.41 for connection to the lower levers 42.43 of the three-point linkage In addition to the coupling pin 40 .. is located approximately in the vicinity of the rear right wheel 110 of the tractor, the link member 112 serving for the connection of the upper lever 111.

   The latter is articulated on the one hand by means of a bearing 113 on the connecting member 112 ot, on the other hand, by means of a support eyelet 114 at the connection point 43 on the tractor 4. As can be seen from Figure 21, the connecting member 112 is arranged very widely outwards, so that the towing bar 7 belonging to a harvest cart which is hooked to the Remporquage clevis 5, can pivot sufficiently, widely laterally to be able, if necessary, to cover also small radius curves, for example when turning at the end of a field.

   The shape of the upper lever 111 and its connection on the machine side as well as on the tractor side are designed so that the lifting struts extending from the lower levers 42,43 to the lift arms of the tractor lifter have sufficient room for be able to use the lifter to lift the unit.



   In Figures 20 and 21, the support eyelet 114 is pivotally connected and with a possibility of form-linked immobilization by a toothed disc or a member similar to the lever 111. Figures 22 and 23 show an embodiment of the upper lever 111 in which a support eyelet 115 is fixed to a strut 117 provided with a toothing 116. The latter engages *

  <Desc / Clms Page number 39>

 pledge in a corresponding counterplate 118 and is held in form connection by a screw 119 on the upper lever 111.

   After loosening the screw 119, the support eyelet 115 with the strut 117 can be set back or extended and one can thus adjust the desired length of the lever. Of course, one can keep in this embodiment also the possibility of pivoting the support eyelet 115, when making the plate
118 on the opposite side as a toothed disc with toothing
120 and that it is brought together with a corresponding counterpart
121.



   Figures 24 and 25 show a possibility for modifying in a simple way the height of the connecting member. In this case, the connecting member connected to the cross member 3 consists of two parts 122, 123 which are slid into one another telcscopi- cally. By means of a common clamping device 124, the adjusted length of the connecting member 122, 123 can be fixed. If necessary, the connecting piece 123 can be made, as shown in figure 25, in a bent shape, In this way, thanks to a rotation of the connecting piece 122, a positional displacement of the bearing 113 and therefore of the articulation point on the device side for the lever is obtained. superior 111.



   Another possibility of adjusting the articulation point on the device side is shown in Figures 26 and 27, according to which the bearing 125 serving for the connection of the upper lever 111 is fixed by screw bands 126 on a plate 128 having ) elongated holes 127. The plate 128 is rigidly connected to the connecting member 112. Figures 28 and 29 show a U-shaped lever consisting of two struts, which is articulated by one of its ends at the point articulation 129 on the tractor 4 and by its branches 130,131 on 132,133 connecting members arranged on the cross member 3.

   The connecting members 132,133 are located outside the coupling points 40,41. This achievement is suitable

 in particular for heavy-mounted devices,
Figures 30 and 31 show a hydraulic washer installation on a tractor 4 which is constituted by a lifting shaft 140 with two lifting arms 141,142 and a hydraulic lifting cylinder 143 with a piston 144 which acts by its piston rod 145 on a lever 146 rigidly connected to the lifting shaft
140.



   To the two lift arms 141, 142 are articulated using lift rods 147,148, the lower levers 42,43 of a common three point linkage. On the lower levers 42,43 is mounted, using the coupling studs 40,41 and a cross member 3, a harvesting device 1, 2 working laterally next to the tractor. The device is mounted in this case without using the upper lever, so as not to occupy the space necessary for hooking the drawbar 7 of a carriage to the coupling yoke 5 of the tractor. A support wheel 150 is supported on the collecting device 1, 2 by means of an arm 149.

   Using a hydraulic working cylinder 151 placed between the frame of the device 1, 2 and the arm 149 of the support wheel, the support wheel 150 and its arm 149 can be pivoted. around the bearing axis 152
During lifting, oil is sent through a pipe 153, from a pump not shown, into the. lifting cylinder 143, so that the piston 144 moves in the cylinder 143 and that it rotates by its piston rod 145 the lifting shaft 140 with the lifting arms 141, 142 and thus lifting through the lifting rods 147,148 the lower levers 42,43.

   If the supply of oil to the lifting cylinder 143 is stopped using a valve 154, the pump delivers into an oil tank, not shown, while the oil which has already entered the cylinder of lifting 143 keeps the piston 144 in its displacement position and consequently the lower levers 42,43 in the raised position.

      We can of course: also introduce such a valve in line 155 leading to the pressure side of the lifting cylinder 1.43, which then makes it possible to select the moment of the lifting of the front end of the apparatus.



   On the device 1,2, stops 158, 159 are provided to limit the pivoting movement of the arm 149 of the support wheel. The stop 159 is produced as an adjustment screw, using which the position of the device above the ground can be adjusted. The support wheel 150 is arranged in front of the counter of gravity S of the device and is located in the embodiment illustrated in the drawing approximately in the extension of the axis 160 of the rear wheels of the tractor.



   According to Figures 32-34, it has articulated on a tractor 4, on the lower levers 42,43 of a common three-point linkage and by means of coupling pins 40,41, a cross member 3. This extends beyond the width of the tractor and carries at its outer end a harvesting device 1, 2 which extends with a reduced construction mode and elongated from the cross member 3 towards the front in the longitudinal direction of the tractor.

   The device 1, 2 with the cross member 3 is therefore articulated at the rear end only on the lower levers 42, 43 so that the space required for the connection of a drawbar 7 of a towed vehicle has the yoke 4 ' hitch 5 of the tractor is completely free, that is to say it is not occupied by the upper lever of the three-point linkage of the tractor. The front end of the device 1,2 is connected by means of a bearing 170 and a corresponding connecting piece 171, for example a rod or a chain, according to the invention, 4 the lifting linkage 172 tractor mower.

   The 170,171 pieces used for the connection

  <Desc / Clms Page number 43>

 with the lifting linkage 182 may be of different construction depending on the type of harvesting device of the tractor or the manufacture of the mower, and they may be adjusted on the device in position and length according to the conditions encountered. Countries,
With tractors and harvesting devices for which there is sufficient space, it is also possible to leave the mower bar on the tractor and connect the front end of the device 1, 2 to the mower pad. In this way, without any modification of the tractor, a simple mounting and lifting device is obtained for a harvesting device working sideways next to the tractor.

   In this case, the rear end of the device is raised by the lift of the tractor and the front end by raising the mower. With a mechanical lifting of the mower by means of a lever 173, the tractor lifter valve must be actuated and the lever 173 brought to the position 173 'when the device 1, 2 is to be raised to the position shown in phantom. If a hydraulic cylinder 174 is provided for the lifting of the mower, this can either be ordered separately with the valve provided for this purpose, or be coupled to the hydraulic system of the tractor lifter, so that the device 1, 2 can be lifted from the ground approximately parallel to the front and to the rear.



   According to figure 35, a cross-member 3 extending laterally beyond the width of the tractor 4, two drum choppers 1, 2 and 1 ', 2' with in-line mower, a spacing corresponding to the width of the lines, for example for corn, The drum mowers 1, 2 and 1 ', 2' are connected to their mowers in line in an indivisible unit, the casing receiving the organs of the in-line mower and chopper part being produced. as a self-supporting frame.

   According to the exemplary embodiment of FIG. 35, the crossmember 3 is fixed to pivot around

  <Desc / Clms Page number 44>

 a vertical stud 180 on a three-point trestle, 161 which has coupling studs 182, 183 for connection to the lower levers 184,, 185 and connection means for the upper lever, not shown in the drawing, of the three-point linkage.



  Drum choppers 1,2 and 1 ', 2' are driven from the tractor PTO shaft via an articulated shaft 186 which leads to an angular transmission 187, fixed to a crossmember 3 and from which the drive rotation is transmitted to the drum choppers by means of a chain mechanism 189 and chain wheels 190. To adjust the drum choppers 1,2 and 1 ', 2' to the width of the rows of plants to be harvested, the attachment can be made to the cross member 3 so that the mutual spacing of the drum choppers 1,2 and 1'2 can be modified. ', so that we can move them on the crosspiece 3.

   The chain wheels 190 on the shaft 188 are then moved together. At the end of the crossmember 3, a support wheel 191, which acts as a follower wheel, has been attached. During work, the crossbar 3 is fixed to the three-point trestle, 181 using a plug 192.

   For transport for example on public roads, after removing the pin 192, the cross member 3 can be pivoted with the drum choppers 1, 2 and 1 ', 2' which are attached to it until the position shown. - shown in phantom in figure 35, behind tractor 4, can

 Drum choppers 2 and 11, 21 can be pivoted around journal 197 to the transport position shown in phantom in figure 37, behind the tractor.



   By additionally removing the journal 197, it is also possible to completely dismantle the devices 1, 2 and 1 ', 2', so that the cross member portion 196 remaining on the tractor becomes available for mounting. another gluing device,
Figure 39 shows an exemplary embodiment with a cross member in two parts, the part 203 connecting to the three-point linkage of the tractor 4 being longer than the cross member part 196 according to figure 37, In this case, a chopper with drum 1,2 is attached to the crosspiece portion 203 and the other ha-

This embodiment further allows the forage harvester to be selectively operated for a smooth line when denied. or conversely, the chopper A outer drum 1 ', 2' was mounted by removing the journal 204 as well as the pin 205.

   The drive shaft 188 is made in this embodiment exactly as in the exemplary embodiment of Fig. 37.



   In the embodiment according to Figures 40 and 41, one drum chopper 1, 2 is attached to a cross member portion 207 exactly as in the embodiment of figure 39, while the other drum chopper 1 ' , 2 'can be raised by pivoting for the transport position about an axis 208 located in the traffic sounds ... to the position shown in phantom in Figure 40.



   The two drum choppers 1, 2 and 1 ', 2' are then linked together by hinges 209 or the like., The crosspiece part 210 serving for fixing the outer drum chopper 1 '., 2' is hingedly connected to the cross member portion 207, in order to allow this lifting movement by pivoting.



   Figures 42 and 43 show a towed forage harvester in which the individual drum choppers 1, 2, 1 ', 2', 1 ", 2", are attached to a cross member 211 which is supported from the ground by two wheels 212 and which is hooked by means of a towing drawbar 213, which can be swiveled apart, to the tow bar 214 of the tractor 4. The driving conditions !. They are then identical to those of the embodiments of FIGS. 35 to 41.

  <Desc / Clms Page number 47>

 



   Figures 44 and 45 show an exemplary embodiment of how the forage harvester 1,2 can also be mounted in front of the tractor 4. In this case, the drum choppers 1,2,1 ', 2 ', 1 ", 2" are fixed on a cross member 215 which is articulated by means of a lever 216 which can pivot in height on the front coupling yoke 217 of the tractor 4. The cross member 215 is hand-held. held in its required position transversely to the direction of travel by means of a stabilizer bar 218 leading to the rear tow bar. In order to be able to adjust the height and raise the forage harvester, the cross member 215 is supported from the ground by support wheels 219.

   The adjustment of the harvesting device and its raising to the transport position are effected by hydraulic cylinders 220, which engage parallelogram levers 221 serving to guide the support wheels.
219. The drive of the forage harvester mounted in front of the tractor can be effected in the usual way from the front drive shaft of the tractor. If there is no front PTO shaft on the tractor, the drive can also be bypassed through a drive shaft 222, from the rear PTO shaft, using a appropriate attached transmission.

   The forage harvester in the embodiment illustrated in Figures 44 and 45 can also be easily mounted on both arms of a front loader. In this case, the stabilization bar 218., the lever 216 as well as the support wheels 219 adjustable in height with the hydraulic cylinders 220 become superfluous.



   In FIG. 46, there is shown a forage harvester produced as a drum chopper 1, with a receiving device in width 230 which is constituted by a receiving drum 231 produced in the usual way and by two conveyor screws. 232 and 233 transverse / arranged between the feed members of the chopper 1 and the receiving drum 231, which ensure transport to the center.

  <Desc / Clms Page number 48>

 



   The product located transversely on the ground is taken up by the receiving drum 231 and brought by the transverse conveyor screws 232233 to the feed or introduction members of the compact chopper 1,
The forage harvester 1 is mounted on the tractor using a mounting frame 234, on the three-point suspension of the tractor 4, of which only the two lower levers 42,43 have been shown and it can be caused to pivot and be immobilized with respect to the mounting frame 234 and therefore to the tractor, about a vertical axis 235.

   The mounting frame 234 is located in a plane below the coupling yoke 5 so that it is possible to hook directly behind the tractor 4, a trolley or a trailer 6, by means of its towing drawbar 7.



   The drive of the hachouae collector 1 takes place in the manner described above from the tractor PTO shaft, via an articulated shaft, not shown, of an angular transmission 187 and the others. transmission parts arranged on the cross member 3 of the mounting frame 234 and leading to the forage harvester 1.



     'The drum chopper 1 is with its receiving device through 230 the previous one (figure 46) outside the tractor track, and at the top in the working position, in an oblique position facing forward and away from the tractor. The receiving device 230 is then placed on the chopper 1 by making an angle corresponding to this oblique position, so that in the working position it has the required transverse position with respect to the direction of work in order to allow the operation of the machine. receiving or collecting drum 231.

   In addition, the receiving device 230 has an eccentric position relative to the chopper 1, on the side 236 located / of the tractor of the receiving drum 231 projecting more beyond the side wall 237 of the chopper. 1 that

  <Desc / Clms Page number 49>

 the opposite end 238. Therefore, it is possible to pivot the chopper 1 with its receiving device on 230 from the oblique position required for working around a vertical axis 235, for transport up to the position shown in dotted lines in the drawing in relation to the tractor 4.

   In the pivoting position, part of the receiving device is placed between the front wheel 239 and the rear wheel 240 of the tractor and the total width of the trnctour and the forage harvester in the pivoting position reaches approximately 2.5m,
The frame of the chopper gatherer 1 can also be made such that the receiving or collecting device can be removed and replaced by a double row mower 241. as shown in Fig. 47. The double row mower 241 is constituted by two outer side walls 242 and 243, on which are supported the introduction or food chains; tion and a middle part 244, located between the two side walls, on which are arranged the inner feed or introduction strings.

   With respect to the chopping device 1, the side wall 242 located on the side of the tractor makes a pronounced angle relative to the latter, while the other side wall 243, which is opposite the tractor, extends with respect to the chopper. 1 approximately:, in a straight line: or with a slight angle outwards.

   The position of the two side walls 242, 243, with respect to each other is then chosen such that their extended center lines 245,246 intersect at a point 247 which is located approximately in the middle between the rows of plants 248 to cut,
Thanks to the asymmetrical construction, the double-line mower 241 receives, with respect to the chopping device 1 arranged obliquely on the tractor 4, the position required for the work, directed according to the direction of movement, and allows a pivoting of the forage harvester for transport to the position shown

  <Desc / Clms Page number 50>

 dotted line in figure 47, between the wheels 239,240 of the plotter,

   without partios of the double-line mower 241 meeting the rear wheel 240 of the tractor,
FIG. 48 represents an embodiment in which a circular mower 249 has been placed on the chopping device 1. The latter has, all retort in the embodiment according to FIG. 46 with a receiving device and 4 the latter. figure 47 with double-line mower, an asymmetrical position with respect to the chopper 1 situated obliquely., which allows a swiveling of the forage harvester from the required oblique position to the necessary transport position to have a total vehicle width of 2.5 m.



   In order to be able to adapt the mounting frame 234 in combination with the forage harvester 1 to different tractor track widths, it may be advantageous to realize with the possibility of lateral displacement the vertical pivot axis 25 re - binding the forage harvester to the assembly frame. In this way, the forage harvester 1 can be brought back as far as possible towards the rear wheel 240 of the tractor, in order to obtain, in the transport position and with the device in the pivoting position, a total vehicle width also reduced. as possible, which is below the maximum value of 2.5 m for narrow track width and tractor.



   According to figure 49, the forage harvester frame
1 is designed so that the in-line mower can be removed and replaced with a receiving or collecting device 250.



   The receiving device 250 which consists essentially of a pick-up drum 251 and a transverse conveyor screw 252 is freely pivotally supported about an axis 254 located in the direction of travel, by means of an arm 253, on the frame of the chopper 1 and it rests at its outer end by means of a support wheel 255 on the ground. For transport, thanks to this oscillating suspension, we can

  <Desc / Clms Page number 51>

 pivot upwards the receiving device 250 about the axis 254 (see figures 50 and 51), so that a total vehicle width is again obtained for the chopping mower and tractor 4 of 2.5 m maximum.



   The drive of the receiving drum 251 can be effected by means of an articulated shaft 256 at will from a shaft of the feed members or of the pressing members of the chopper 1 ..



   The transverse conveyor screw 252 is driven, via a chain mechanism 257 or the like, from the receiving drum 251. In order to exclude damage or deformation of the receiving device 250 or the articulated shaft 256 during operation. (an inadvertent start-up of the chopper 1 when the receiving device is in the pivotally raised position) the drive transmission can be. made automatically disengageable by means of, for example, a coupling known per se or a similar member, during the upward pivoting movement.



   Figures 53 and 54 show an in-line mower 2 which is formed by two side parts 260.261 which, viewed from above, have a generally triangular shape in their front area (figure 53). The side portions 260 and 261 are disposed widely apart from each other at their front ends 263,; 264 and they converge rearwardly to a point from which they then extend parallel to each other, to form an intake passage 265 extending from front to rear.

   As the forage harvester moves forward, the side portions 260 and 261 pass along the opposing sides of the erect grain and the grain thus passes through passage 265 to be fed into the chopping device. which connects to it, which has no longer been represented.



  * In order to allow a correct introduction of the cereals,

   The latter is rotatably supported on a stud 273, which is rigidly connected to an angular guide piece 274. The latter is connected by two retaining studs 275, which pass through a slot 276 made in the side part 260 or 261, to the interested lateral part, with a possibility of displacement inside the slot 276. In the vicinity of the guide part 274, there is provided a counter-support 277 rigidly connected to the sides 260 and 261 against which s' supports a spring 278 acting on the guide piece 274.
