Description

SPECIFICATION Combination of apparatus for cultivation of the soil The present invention relates to a combination of apparatus for cultivation of the soil etc., which can be built onto a tractor and which consists of at least one working appliance for soil loosening and/or fertilization, which can also be used by itself and which is provided with a supporting frame and to the rear of which at least one second working appliance for seed bed preparation and/or for fertilization and/or for drilling or planting and/or for the cultivation or harvesting of agricultural plants can be detachably affixed by means of traction arms known per se or else rigidly but preferably in such a way as to be adjustable in height.

Such combinations of working appliances, of which the working tools penetrate to a great depth in the soil, with further working appliances, of which the working tools are situated on the surface of the soil or in the uppermost layer of soil or at a certain distance above the ground, and with which each subsequent working appliance is articulated to the preceding appliance by traction arms, powered lifting linkage or similar devices, adjustable in height, and are at least partly guided on the surface of the soil by means of scanning wheels, suffer from the drawback that the minimum lengths which the traction arms, powered lifting linkages etc., are required to have in order to adapt individual appliances satisfactorily to the ground and also the over-all lengths of the supporting frames of the appliances with the working tools mounted thereon result in unacceptable over-all lengths of the combinations of apparatus as a whole. As a rule, therefore, because the position of the centre of gravity and the total weight of the combinations prevent three and especially a still greater number of working appliances which can also be used by themselves from being built on, either because the lifting power of the powered lifting apparatus is inadequate or because the front axle of customary tractors relieved of the weight to such an extent that their steer-ability is either unduly limited or even eliminated altogether.

The invention solves the problem of surmounting these drawbacks and providing a combination of apparatus in which any desired soil loosening and/or fertilization appliances, even usable separately, can be combined with one and a number of further seed bed appliances and or appliances for the cultivation or harvesting of agricultural plants in such a way that the over-all length of the entire combination of apparatus is kept as short as possible and the position of the centre of gravity is situated as near as possible to the rear axle of the tractor.

Furthermore, the combination enables different individual appliances to be coordinated in a vertically movable or rigid but preferably in a vertically adjustable manner and combinations of 'different types of individual appliance to be converted without difficulty.

The invention enables this object to be achieved as a result of the fact that the traction arms of the second working appliance, as viewed from above, are detachably affixed to articulation points situated in front of the frame of the first working appliance.

The traction arms of the second working appliance, viewed from above, are preferably situated to the side of the supporting frame and/or the outermost working devices of the first working appliance.

The second working appliance may also be optionally connectable to additional articulation points, of a kind known per se and situated on the rear and preferably on a central portion of the first working appliance.

The traction arms of each subsequent working appliance are advantageously connectable in an easily detachable manner, by means of rapid couplings of a kind known per se, to articulation points of the working appliance by which it is preceded.

In a preferred embodiment of the invention the coupling devices provided in the central section of the second working appliance take the form of attachment brackets of a kind known per se or of guide arms and are connected in an easily detachable manner to the frame of the second working appliance by means of rapid fastening devices such as plugs.

In a preferred combination of apparatus the first working appliance is a layer grubber of a kind known per se, the second a rotor harrow of a kind known per se and the third a drilling machine of a kind known peruse.

In another advantageous combination the first working appliance is a beater mower of which the frame is fitted with loosening devices of a kind known per se, the second a rotor harrow of a kind known per se and the third a drilling machine of a kind known perse.

The drilling machine known per se can be mounted on a rotor harrow known per se so tnat it can be easily detached therefrom and will be pivotable above an axis transversal to the direction of travel.

The third working appliance is preferably connectable to either the second or to the first working appliance, as desired. At least the first and the second working appliances are preferably fitted with scanning wheels, separately adjustable in height.

In a further embodiment of the invention the traction arms fitted to a working appliance and serving for the attachment of the subsequent appliance are detachable in a manner known per se and are attached with a double joint so as to be pivotable vertically and also laterally but can be laterally secured in the working position by means of stops which are preferably adjustable in the lateral direction. The scanning wheels of a first working appliance are preferably affixed, in a detachable and vertically adjustable manner, in a compartment which is provided on the side of the appliance and which is constructed as a bridge and under which extend traction arms of a further working appliance in such a way that they are vertically movable within certain limits.

In another example the articulation points, as seen from above, are situated in front of the foremost working device of a working appliance.

In a further example of the invention the second working appliance is affixed to the first working appliance by means of traction arms articulated to the side thereof, a third working appliance being affixed thereto by means of traction arms extending beyond its central zone.

The invention will be explained in greater detail by reference to examples shown in Figure 1 to 7, in such a way that characteristics illustrated in or described by reference to one diagram are to be transferable mutatis mutandis to other diagram.

The drawings are as follows: Figure 1 a schematic lateral view, Figure 2 a schematic plan view of a combination of apparatus, Figure 3 a schematic lateral view, Figure 4 a schematic partial plan view of another example, Figure 5 a schematic partial lateral view, Figure 6 a schematic partial lateral view of another example, and Figure 7 a schematic lateral view of a combination of apparatus consisting of three appliances.

As shown in Figures 1 and 2 a second working appliance 2 for the preparation of seed beds is affixed, by traction arms 1 rigidly attached thereto, at articulation points 5 situated on the frame 3 of a first working appliance 4 for the loosening of the soil, and in front of the said frame 3 of the said appliance 4, in a detachable manner.

The articulation point 5 may take the form of a rapid coupling 7 of a kind known per se.

The working appliance 4 is provided with additional articulation points 6 situated on both sides of its imaginary longitudinal median plan in the direction of travel, and these points may likewise take the form of a rapid coupling device 7 so that further working appliances can be coupled to the working appliance 4, both to the side of the frame and in a central zone behind the attachment bracket 8.

The working appliance 4 and the further working appliances 2, 17, 18 and 19 can be guided on the ground as required by means of vertically ajustable scanning wheels 9.

In the example shown schematically in Figures 3 and 4 the first working appliance consists of a beater mower 27 fitted with compartment 1 5 which is constructed as a bridge and under which extend traction arms 1 6 of a second working appliance 2, which are detachably affixed to the articulation point 5 of the beater mower 27 and which can move in a vertical plane, within certain limits, underneath the compartment 1 5 constructed as a bridge.

Loosening devices 29 are affixed in a vertically adjustable manner to the frame 28 of the beater mower and are identically similar to the loosening device of a layer grubber 24.

Central traction arms 20 of a drilling machine 26 act on the frame 23 of the second working appliance, i.e. a rotor harrow 25, and are connected in a vertically adjustable manner, via three-point upper guide rods, not shown in detail in the drawing, with the said rotor harrow 25, and can be guided on the ground by wheels of their own.

In order to enable the seed box on the drilling machine 26 to be mounted as far as possible above the frame 23 of the rotor harrow 25, the attachment bracket 8 of the said rotor harrow is constructed so as to be easily detachable by means of plugs 22. When the rotor harrow 25 is used as a separate appliance the said attachment bracket 8 is required for attachment to a tractor and can therefore be remounted without difficulty.

As shown in Figures 5 and 6, the traction arms 21 of the drilling machine are affixed via a double joint 10 to an articulation point 6 of the rotor harrow 25 in such a way that for attachment and removal they can be pivoted to one side and moved vertically, in the vertical plane, into the working position, but are accurately fixed in the lateral direction, when in the working position, by means of adjustable stops 30 screwed onto the said rotor harrow 25.

The drilling machine 26 is provided with front seeding blades 11 suspended on parallelograms 12 and with rear seeding blades 14 articulated in the known manner to traction bars 13.

As may be seen from Figure 7, the articulation points, as viewed from the side, can be advantageously situated in front of the point of the foremost working device 31.

It is also possible for the working appliance 2 to be mounted to the side of the articulation points 5 of the frame 3 of the first working appliance 4, while at the same time the working appliance 3, e.g. a drilling machine 26, is likewise detachably affixed, by means of traction arms extending beyond the working appliance 2, to the articulation points 6 provided in the middle of the frame 3 of the working appliance 4.

This system offers the advantage that the working appliance 2, without being additionally subjected to the weight of the drilling machine 26, can be easily adapted to all irregularities in the ground and, over all, can move upwards out of the way when its driven prongs come in contact with stones, so that damage is avoided.
