Description

BACKGROUND OF THE INVENTION The present invention relates to an interlocking unit for attaching a family of adapters with different working widths to different types, mainly self-propelled or trailed silos.

It is known that self-propelled or trailed silos can be fitted with different adapters for different purposes and working widths, depending on the purpose of harvesting, with crop-cutting and retracting devices or with finger pickers. A common feature is that the crop removed from the ground - cut and immediately retracted or picked from a carpet order - is transported into a transport trough, which is forced into a shredding structure by a relatively homogeneous mass through a hopper hopper. It is also known that adapters are manufactured in different working widths, depending on local or natural conditions and the harvesting technology used. Increasing the working width increases the problem of ground tracking, which manufacturers try to address, among other things, by a variety of ways to suspend the adapter.

A further problem with increasing the working width, especially in the case of suspended adapters, is the fact that, in the raised transport position of the adapter, the smaller or larger ripple resulting from the unevenness of the ground exposes the suspension to considerable torsional stress.

A solution to the suspension is disclosed, for example, in patent application HU 172 116, where the adapter is connected to a self-propelled forage harvester by means of a pivot-mounted pivoting arm with a cross-pivot hook. With this design, it is possible to track the adapter in parallel to the direction of travel, and to a limited extent in the transverse direction. The disadvantage of this solution is that the attachment of the implement to the adapter is complicated, requiring great attention, precision and considerable time from the operator. A further disadvantage is that, in the transport position, the transverse swinging motion of the adapter is transmitted to the hanger, which leads to fatigue, or the hanger must be oversized.

Another solution for suspending the adapter to a base machine is disclosed in HU 180 200. In this design, the base machine is connected to a tilt-mounted chassis frame and to the chassis frame also a tilt-mounted suspension frame. Attached to the suspension frame is a forward pivot pin (longitudinal pin) which fits into the properly formed bearing housing of the adapter. This solution allows longitudinal and transverse ground tracking of the adapter. However, this solution also has the disadvantage that, in the transport position, the transverse oscillation of the adapter is compensated by the cross-pins on the frame structure, which is ultimately transmitted to the chopper shaft. A further disadvantage is that the suspension elements are complex and therefore bulky.

It is also known that the various agricultural machine manufacturers provide very different solutions for the crop receiving apertures of the self-propelled or trailed silos and the transfer hoppers of the adapter conveyors, as well as the suspension mode of the basic machine and the adapter.

The adapter is the unit most exposed to wear during operation and therefore has to be replaced from time to time. Experience has shown that, in the absence of an adapter for a specific base machine, or vice versa, non-core components of the base machine and the different types of adapter are drastically modified, cut or welded from parts of the conveyor, hopper, and suspension frame.

It is also an experience that the owners of small farms, which are widespread in Western Europe, exchange and rent their machines and units according to seasonal work. Even in this case, the base machine and the adapter are often incompatible.

It is an object of the present invention to overcome the above disadvantages, that is, to provide an interlocking assembly which, while retaining specific elements of known and applied structural solutions, allows various self-propelled or trailed silos to be connected to adapters of different types and working widths.

To accomplish this task, the realization has been made that wide variability is possible by inserting an intermediate unit between the adapter and the self-propelled or trailed silo, which has a uniform connection on the adapter side and a specific connection on the base machine.

Based on the above recognition, the task is to connect the adapter family with different working widths but with a uniform connection to different types of silos, where the adapter has a crop design opening in all variants and a king bearing housing one part of which comprises a suspension frame connected to the silo and fitted with a king pin on the lower holder which fits into the adapter king-bearing housing and the other part of which is a crop transfer hopper according to the invention, one end of which it has a standardized flange, while its side walls can be fitted to the respective silage and defining a freestanding garage space extending through the suspension frame, but the suspension frame is provided with at least two suspension elements arranged in pairs suitable for connection to the respective silo, at least one spring-loaded side-latch mounted on the lower support of the suspension frame provided with stops and at least one side with a positioning unit that cooperates with the adapter positioning bracket.

According to a preferred embodiment of the invention a

EN 208 456 Positioning unit B comprises a positioning plate with a through hole that can be overlapped with the fixing hole of the positioning bracket and extends parallel to the king pin and always has the same distance from the king pin as the position of the mounting pin mounted on the adapter. the through hole of the plate is always at the same height in the vertical plane relative to the king pin on the right and / or left side of the hanger frame.

In the above embodiment, it is also desirable that the positioning unit comprises a securing pin which is guided through a positioning plate and a positioning bracket by an in-position, two-position spring-loaded connecting member.

In a preferred embodiment of the insert unit according to the invention, the suspension frame is connected to a self-propelled or trailed silo by means of a quick coupling.

In another preferred embodiment of the insert unit according to the invention, the suspension frame is connected to the self-propelled or trailed silo by means of a fork-type locking pin.

According to the invention, the side support is preferably formed of a tension spring surrounding a threaded spindle, a spring plate supporting it and a tensioning nut supporting the spring plate.

Finally, it is also advantageous to have an embodiment in which a drive transmission unit is connected to the drive receiving extension of the adapter in the region of one of the lower corners of the suspension frame.

The invention will now be described in more detail with reference to the accompanying drawings, in which some exemplary embodiments of the present invention are illustrated.

As can be seen from the top view in Fig. 1, the insert unit 1 according to the invention serves to connect an adapter A, in particular a member of an adapter family with different working widths but with a uniform connection, to any self-propelled or trailed silo. In the present embodiment, the silo S is shown as a self-propelled silo, while the adapter Λ consists of a cutting unit 2, a feeder 3, a conveyor trough 5 and a conveyor screw 6 which are integrated in a frame 17 known per se.

2 is a so-called finger pick-up, the main units of which are the pick-up 4 integrated in the frame 17, the conveyor screw 6 and the conveyor trough 5 with the crop transfer opening 7. The adapter A, shown in Figure 2, is supported by slides 18 and / or rollers 19 when in the operating and inactive position. The stand helyzet adapter also comes with a stand 20 for off-site storage.

In the central part of the frame 17 of the adapter A, a king-end bearing housing 8 extending in the direction of travel and facing towards the silo S is fixedly fixed by a releasable connection, which is in fact a uniform sliding bearing with a flange. A positioning bracket 37 with a mounting hole 38, shown in more detail in FIG. 10, is mounted at a distance H to the right and left of the ridge bearing housing 8, a function of which will be discussed in more detail below.

In addition, Fig. 2 shows a drive receiving extension 9 which can be mounted on the right or left side of the adapter A, the end of which is formed in the form of a uniform torque-transmitting shaft 21 on the king-end housing 8. This shaft 21 is pivotally mounted in the drive receiving extension 9, while its other end engages the drive mechanism of the adapter A.

Since the adapter A and the self-propelled or towed silo S are not part of the invention, they will not be further described, or will be touched, insofar as they are related to the invention. It should be noted, however, that the invention relates not only to the exemplary adapters A, but also to any harvesting machine, e.g. adapters of a similar type and construction for a combine or self-propelled carrier unit. In any case, it is to be emphasized that the optimum applicability of the insertion unit 1 according to the invention is that the adapters A attached to the various silos 5 have a standardized crop transfer opening 7, king bearing housing 8, drive receiving extension 9 and positioning brackets 37.

As shown in Fig. 3, the two main parts of the insert unit 1 according to the invention are provided by a crop transfer unit 13, which is standardized on the adapter side

EN 208 456 Β and a surrounding suspension frame 12 (of which the structure is described below), the lower support of which is provided with the standardized king pin 10 which fits into the unified king-bearing housing 8 of the adapter A.

Figures 4 and 5 illustrate that the order of the fixing holes 24 in the flange 7 surrounding the opening of the crop transfer conveyor 5 and the fixing holes 24 'in the uniformly formed flange 11 of the crop transfer hopper 13 are always the same; The flange 11 can be releasably connected to the flange 7 of any of the standardized crop transfer apertures of the adapter A. The flange forms a rigid unit with the side walls 22 ', 22 "and 22' 'of the crop transfer hopper 13, the side walls defining a hopper space 23 having a transfer side contour adapted to the receiving opening 25 of the self-propelled or trailed silo and freely extending through the suspension frame 12. Because the receiving apertures of the self-propelled or trailed silos S are different for each type, the sectional contours taken along the side walls 22, 22 ", 22 '" in any plane of the hopper 23 are different from one another and type, as opposed to its contours are always the same. This design ensures that the crop flowing through the hopper 23 is of the same or nearly the same homogeneity as the self-propelled or trailed silo S and the adapter A are of the same type.

Figures 3, 7, 8 and 9 show various embodiments of the suspension frame 12. Basically, the hanging frame 12 is pivotally mounted in the king-bearing housing 8 of the adapter A by means of the united king pin 10 in a plane perpendicular to the direction of travel. According to the invention, the suspension frame 12 is assigned to a side support 16, two stops 15 and at least two suspension members 27 or 27 'arranged in pairs. The suspension frame 12 also includes, for some types, a drive unit 14 and a relief spring 28.

The side support 16 comprises, as shown in Fig. 7, a combination of a tension spring 29, a spring plate 30 supporting it, a threaded spindle 31 surrounded by a tension spring 29 and a tension nut 32 supporting the spring plate 30, attached to the hanger frame 12 and the threaded spindle 31 to the frame 17 of the adapter A.

The two stops 15 are rigidly mounted on the lower bracket of the hanger frame 12 on the adapter side, on either side of the king pin 10, arranged in such a way that one defines the ground tracking (lateral tilt) of the adapter ével by striking the frame 17. The angle range α is preferably ± 5 °, but may be varied as necessary.

The suspension members 27 and 27 'are rigidly connected to the suspension frame 12 on the self-propelled or trailed silo side, so as to fit snugly against the counterpart on the self-propelled or trailed silo S.

In the embodiment of Fig. 7, its suspension members 27 are formed as quick-release switches on the lower right and left sides of the suspension frame 12.

In the embodiment of the suspension frame 12 shown in Figures 8 and 9, a fork-shaped suspension element 27 'is used which is rigidly secured to the lower and upper corner points of the suspension frame 12 and is connected to the self-propelled or towed silo S .

As outlined above, the suspension frame 12 has a specific configuration of the self-propelled or towed silo S, so that the configuration and arrangement of the suspension members 27 and 27 'and the locking pin 34 may vary not only according to the embodiments described but also individually.

As shown in Figs. 9 and 10, the mounting frame 12 further includes a position retaining unit 35 which provides Adapter A with sufficient stability when inactive or in transport position. As shown in Figures 9 and 10, the positioning unit 35 comprises a positioning plate 40 with a through hole 43 which can be aligned with a mounting hole 38 of the positioning bracket 37 mounted on the adapter A and is rigidly attached to the right and left sides of the hanger frame 12. The positioning plate 40 extends parallel to the king pin 10 and, in a horizontal plane, the distance Hj relative to the king pin 10 is always the same as the position H of the positioning bracket 37 mounted on the adapter A. The through hole 43 of the positioning plate 40 is always at the same height h in the vertical plane relative to the king pin 10 on the right and / or left side of the hanger frame 12, so that the axis of the mounting hole 38 and the through hole 43 always coincide.

Positioned on the positioning plate 40 is a bracket 42 which includes a two-position spring-loaded coupling member 41 and a retaining pin 39 passed therethrough. These together form the positioning unit 35.

In addition, the 12 hanging frames can be supplemented with a

3, as shown in FIG. 3, with an angular drive 36 which provides a connection of a drive unit 14 mounted in the region of one of the lower corners of the hanger frame with the drive receiver extension 9 of the adapter A.

Since the linkage between the suspension frame 12 and the self-propelled or trailed silo S is made up of well-known structural elements, further detail is omitted. It should be noted, however, that the flange 11 of the crop transfer hopper 13 embodying the essence of the present invention may, of course, be supplemented by a further unified constriction or expansion joint corresponding to the crop transfer port 7 of the adapter A.

The insert unit 1 according to the invention is used as follows:

Different Type To connect the adapter to the self-propelled or trailed silo S, the spacer unit 1 with 12 hanging frames and 13 products is selected.

The hopper hopper HU 208 456 Β can be connected to a particular self-propelled or trailed silo. If the latter has fittings which prevent the connection, these will naturally be dismantled. The same is done on the adapter A if the crop transfer opening 7 thereon is not of the desired configuration.

Subsequently, the crop transfer hopper 13 of the selected intermediate unit 1 is mounted on the conveyor trough 5 of the adapter old with releasable fasteners 24 and 24 'through uniformly spaced mounting holes 24 and 24' on the flange 11 and on the flange 7 of the transport trough 5.

Next, the suspension frame 12 is connected via the king bearing housing 8 on the adapter A with the king pin 10 so that the crop transfer hopper 13 is guided freely through the suspension frame 12. The self-propelled or trailed silo S and the suspension frame 12 are then connected and secured, depending on the design of the suspension members 27 and 27 'respectively. Further, the drive transmission unit 14 is connected to the shaft stub 21 of the drive receiving extension 9. Finally, the adapter A is offset from the ground by loosening or tensioning the tension nut 32 of the side support 16.

By lifting the 20 support legs and taking other professional measures, the transport - operation - can be started.

When the adapter is lying on the ground during operation, the locking pin 39 of the positioning unit 35 is pulled out and the connection between the positioning bracket 37 and the hanging bracket 12 is removed by turning it 90 °. In the case of transport or high-yield harvesting, the reverse is the case.

The necessary replacement of the adapter A or the self-propelled or trailed silo S is done in the same manner, i.e., the mismatched parts or the entire intermediate unit 1 are removed and the newly selected intermediate unit 1 is installed in the same order.

The most important advantage of the present invention is that the necessary and / or expedient replacement of the adapter A mentioned in the introduction can be easily and quickly accomplished without drastic modification, and self-propelled or towed S silos can be better utilized according to different seasonal work. Users do not depend on the type of their existing base machine, and can choose to use the A adapter with any width and function, by selecting the appropriate type of spacer unit 1.

It is a significant advantage that production and distribution costs are reduced and spare parts supply is simplified.
