Description

harvester

The invention relates to a harvesting device for harvesting maize or the like stalk-like crop according to the preamble of claim 1 or claim 8 or claim 13.

From DE 33 24 899 C2 a harvesting device is known which has cutting tools suspended in an ash chain for separating the straws of the harvested material, the link chain also being provided with suspended holding means for conveying the separated straws. These are fed to the entry opening of a chopper or the like. For this purpose, a feed area is provided between two endless chains arranged in mirror image, in which the chains are also deflected. In the area of this deflection, the stalks picked up are brought together, which results in a considerable amount of crop being produced in this area. Accordingly, there is a risk here that the crop is not completely removed by the chopper or the like, but builds up in front of its inlet opening. Furthermore, crop remains stuck to carriers of the chain, in particular leaves and the like, long-fiber components during the entire circulation of the conveyor, which means that there is a risk that the transport function of the carriers deteriorates during the period of use.

The invention is based on the problem of reducing the risk of adding a conveyor. The invention solves this problem by a harvesting device with the features of claim 1, claim 8 and claim 13, which can be realized individually or particularly advantageously in combination. Further advantageous embodiments are given in claims 2 to 7, 9 to 12 and 14 to 32.

The formation of a shear bar according to claim 1 ensures that the cutting means underneath the shear bar are freed of stuck crops, for example leaves or the like, which can wrap around the cutting means during operation. This is particularly advantageous in the maize harvest, in which dead, long-fibrous leaves which are very tough when moistened can wind around the cutting means, which are designed, for example, as hook-shaped knives.

With a fixed shear bar, there is little design effort. In addition, the danger is counteracted that bearing parts of a movable shear bar can become clogged during operation.

Carriers arranged above the cutting means are particularly advantageously assigned to the revolving endless conveyor and overrun the counter cutting edge during operation, so that the cutting means and the carrier surround it on the top and bottom sides. The risk that plant parts can squeeze into the gap between the cutting means and the counter cutting edge is thus significantly reduced. It is reliably guaranteed that in Direction of conveyance in front of the cutting means and the plant parts lying in the driver are cut by the shear bar. The drivers located above the cutting means therefore act as a clearing element for the shear bar. The distance between the drivers and the shear bar as well as between the shear bar and the cutting means must be kept as small as possible to ensure the cutting process of long-fiber plant parts without the risk of the parts hitting each other.

A clearing of the chain links is made possible in particular by the wipers according to claim 8, wherein clogging of the spaces between the wipers and the inlet opening of the chopper or the like processing device through openings between the clearing elements facing the chain and the spaced brackets of the wipers arranged are. Particularly in the case of wipers which are essentially parallel to the direction of travel and in which the openings form lateral passages, it is ensured that in the storage space in front of the inlet opening of a chopper adjoining the endless conveyor at the rear, plant and / or soil residues which can no longer be absorbed can be removed laterally would otherwise build up clogging in front of the inlet opening is ensured.

Since the wipers clear the chain area above the cutting means, the features of claims 1 and 8 can preferably be in grain sizes to prevent clogging at different heights before the chopper's inlet opening. be formed combination, but also a single realization of one or the other features contributes to problem solving.

For a harvesting device with a link conveyor, for example a chain conveyor, as well as for other conveyors, for example a conveyor drum, it is particularly advantageous to provide a cleaning device which sweeps over the outwardly directed cutting and / or holding means in a movement which is in the same direction as their direction of travel , As a result, plant parts which have wrapped around the cutting or holding means from the front, for example plant remains in the form of dead, moist, long-fiber leaves, can be lifted off the cutting or holding means. It is particularly advantageous if the cleaning members sweep over the cutting or holding means at a speed which is higher than their rotational speed. Then, for example, a single holding member can be over- and / or under-run several times by a cleaning member. In any case, the unidirectional movement reliably ensures that the wrapped sheet material or the like is lifted off, since further wrapping, such as a flat application of a sheet to a driver, is reliably prevented.

The cleaning members can work both without contact and with contact, for example as brushes or the like. Further advantages and details emerge from the exemplary embodiments of the subject matter of the invention described below and shown in the drawing.

The harvesting device 1 according to the exemplary embodiments is designed as a self-propelled machine and comprises an attachment 2 which cuts and picks up the crop 3 by means of two endless conveyors 4, 5 designed as link chains, and an inlet opening 6 of a further processing device, located in the middle area between the link chains 4, 5, here of a chopper.

Instead of using two adjacent endless conveyors 4, 5, it would also be possible to operate a harvesting device 1 with only one revolving endless conveyor 4 or 5, on the latter lateral end area would then be the feed to the inlet opening 6 of the chopper.

The endless conveyors designed as link chains 4, 5 are designed as mirror images of one another and run in the direction of arrows U1 and U2 with their working strands 4a and 5a (FIG. 2) towards a vertical longitudinal center plane of the harvesting device 1. The feed area 30 to the inlet opening 6 of the further processing device is located in the area of this vertical longitudinal center plane.

Due to the working strand areas 4a, 5a of the link chains 4, 5 arranged transversely to the direction of travel F, a crop strip with a large number of plant rows 3a arranged next to one another can be harvested. The harvesting device 1 can also be used independently of the rows. In general, however, the maize fields are grown in rows and also harvested, which has the advantages that steering machines can be used for the harvesting devices 1, which feel the position of the rows 3a and carry out a corresponding guidance of the harvesting device 1 row harvesting achieves a quieter driving style, since there is an accumulation of soil in the area of the plant rows 3a, which leads to a driving style of the harvesting device 1 which fluctuates unevenly when driving over it at an angle. Because of the recesses between the rows 3a of crops, it can happen that a constant cutting height is not always achievable when the crop is crooked or at right angles to it. There is a risk that the cutting and feeding device will bump into the ground and thereby soil and Picking up dirt and pulling it into the device or that the corn plants are cut too high.

In the illustrated embodiment of a harvesting device 1 with two link chains 4, 5 as endless conveyors, a divider tip 7 is provided in the middle area, which divides the feed area 30 and rejects middle rows of crops 3a towards the side link chains 4 and 5. The link chains 4, 5 perform the function on the one hand of separating the stalks 3 from the roots and, on the other hand, of conveying them to the inlet opening 6 of the further processing device. The link chains 4 and 5 are held in frames 10, 11, these being pivotable overall by means of support frames 8, 9 about pivot axes lying approximately parallel to the longitudinal axis of the vehicle. As a result, they can be pivoted between an operating position lying parallel and essentially horizontally next to one another into a substantially vertical transport position, in which the harvesting device 1 consequently takes up a reduced width. With a standard distance of about 75 cm between the crop rows 3a, 10 rows can be harvested in the operating state with a device width of 7.5 m. It can additionally be provided that, in the transport position of the endless conveyors 4, 5, a hydraulic or similar drive element causes a vertical displacement of the pivot axes carrying the attachment 2, so that the total height of the harvesting device 1 in the transport position is reduced by a few 10 cm, for example for the passage of low bridges or gate entrances can be compared to the position in which the frame 10, 11 holding the endless conveyors 4, 5 is pivoted. It is also possible that the conveying direction of the endless conveyors 4, 5 runs obliquely to the crop rows 3 a, wherein a plurality of endless conveyors 4, 5 form an inclined feed area between them to an inlet opening 6 of a chopper or the like. For this purpose, more than two endless conveyors 4, 5 can also be provided.

The link chains 4, 5 are formed from chain links 14, 15, each of which is designed as a single functional unit and is provided with cutting means 16 in its lower region. A cutting plane S is thereby formed, in which the stalks of the crop 3 are separated. For this purpose, the cutting means 16 can be designed, for example, in the manner of an angle knife and either cut off the blades in a free cut or, as in the exemplary embodiment, interact with a fixed or movable shear bar 29. To guide the separated stalks during the conveyance, spring-loaded brackets 24 are provided in front of the working strand 4a or 5a of the chains 4, 5.

Above the cutting medium plane S there is at least one holding plane H1 comprising holding means 17, the holding means 17 causing the separated straws to be conveyed on to the feed area 30 and from there into the entry opening 6. A better holding results with a second holding plane H2 which is formed by holding means 18 and which is parallel to the first holding plane H1. The link chains 4 and 5, which each convey towards the center in the exemplary embodiment, that is to say have opposite conveying directions U1 and U2, correspondingly have mirror-symmetrical chain links 14 and 15, respectively. In the exemplary embodiment, the cutting means 16 are designed as hook-shaped knives, the cut taking place in the inner curvature of the hook in cooperation with the shear bar. The holding means 17, 18 are also inclined, in order to enable the separated stalks to be laterally inclined against the direction of rotation U1, U2. The cutting means 16 can be interchangeable with the chain links 14 or 15 as wear pieces and, for example, screwed to the latter or fastened with pins. The cutting means 16 cooperate with the fixed shear bar 29, which is assigned to the frame 10 or 11, wherein the angling of the cutting means 16 ensures that the stalks are drawn in in the direction of this shear bar 29. Instead of a fixed shear bar 29, rotating cutting disks or oscillating blades can also be used, which work either in free cut or in cooperation with the cutting means 16.

The straws conveyed by the endless conveyors 4, 5 collect in the central feed area 30 of the harvesting device 1, in which they are fed to the chopper inlet opening 6. This increases the risk of blockages in this area. For example, lower leaves that hang down to the ground, especially when moistened, can become very loose show tough behavior to wind the cutting means 16 and thereby reduce their effectiveness.

A shear bar 31, which is parallel to the cutting means 16 and just above their plane of movement, is therefore arranged in the feed area 30 and is undercut by the cutting means 16 when the endless conveyors 4 and 5 rotate. A counter cutting edge 31 can be provided for each circulation conveyor 4, 5. A common shear bar 31 can also be arranged for several circulation conveyors 4, 5. In the exemplary embodiment, the counter cutting edge 31 is stationary relative to the frame 10, 11 carrying the endless conveyors 4, 5.

In addition to the version of the chain links 14, 15 shown in FIG. 2, these can have, according to FIGS. 3 to 6, for increased effectiveness of the clearing of the cutting means 16, drivers 32 which are located just above the cutting means level S, which are also like the holding means 17 and 18 and The cutting means 16 point outwards and overflow the shear bar 31 in operation at a close distance. Each cutting means 16 in the exemplary embodiment is assigned exactly one driver, which is arranged vertically above the cutting means and which, with its front edge in the circumferential direction U1 or U2, stands above the inner curvature region of the hook-shaped cutting means 16.

The vertical distance between the driver 32 and the shear bar 31 is approximately the same as that between the shear bar 31 and the cutting means 16 (FIG. 6). This distance is approximately in the range of 0.5 to 3 mm. A distance of approximately 2 mm is particularly advantageous, on the one hand, to prevent crops from being placed in the intervals and, on the other hand, to be able to compensate for manufacturing tolerances.

As can be seen in FIG. 10, in a particularly advantageous embodiment, the upper driver 32 is designed such that it has rear projections 52 which engage in corresponding recesses in the deflector plate 21 designed as a steel plate and are welded to the rear thereof. As a result, only the driver 32 projecting as a plate body with rectangular edges to the deflector plate 21 is arranged on the front side of the deflector plate 21, without the edge region being widened by weld seams.

As can also be seen in FIG. 10, the holding means 17 is rounded in the first holding plane H1, so that these are no longer exact parallelogram bodies. The cover plate 53, which covers the chain links 14, 15 towards the top, is in one piece for each chain link 14, 15 and has an offset edge 54, so that the cover plates can slide over one another in the deflection area.

The individual chain links are held via bearings 55 in a guide rail 56 parallel to their direction of rotation U1, U2, so that there is only a rolling friction between the chain links 14, 15 and the guide rail 56. Furthermore, it is visible in FIG. 11 that the cutting means 16, which should be easy to replace for reasons of wear, is held with only a single central screw 57; a more extensive securing of the position takes place by means of a bent tab 58, which is inserted into a recess 59 of the cutting means 16 engages.

The cutting edge 43 of the counter cutting edge 31 is curved in such a way that it is excluded in the direction of the orbit of the link chains 4 and 5 and therefore forms a guide in the direction of the chain, this guide cooperating with the guide through the hook-shaped cutting means 16. Material lying in the space between the shear bar 31 and the cutting means 16 cannot therefore escape laterally, but is cut at the cutting edge 43 of the shear bar 31.

A wrapping of approximately leaf portions in the crop around the cutting means 16 is largely prevented by the overlying drivers 32, portions that have been placed in front of the cutting means 16 and the drivers 32 are crushed in any case by the intermediate cutting edge 31.

Wipers 33 are arranged in the feed area 30 in order to clear the link chains 4 and 5 of crop and feed it to the inlet opening 6. The wipers 33 have a rear bracket 34 in the direction of travel F, from which support means 35, approximately substantially horizontally extending metal sheets, extend in the direction of travel and on their end facing away from the bracket 34 the chain links 14 and 15, respectively Wear clearing elements 36.37. The clearing elements 36, 37 are upright, are adapted to the deflection of the link chains 4, 5 in the feed area 30 and each extend between two levels H 1, H 2 of the holding means 17, 18 or between the level of the drivers 32 and the first holding level H 1. The chain links 14, 15 have, for better interaction with the clearing elements 36, 37 of the wipers 33, closed front surfaces 21, 22 in the manner of deflection shields. Alternatively, it is also conceivable for open spaces between adjacent joint axes 19 and 20 of chain links 14 and 15 to be closed from behind by teeth of a deflection wheel in the region of the deflection.

However, the closed front surface 21, 22 serves as a deflection shield which prevents crop material from penetrating into the inner region of the chain, and is particularly advantageous in this respect. Lateral openings 40 are located between the holder 34 of the wipers 33 and the clearing element 36 or 37, through which the pent-up plant residues can escape laterally in front of the inlet opening 6 if plant residues are too high.

In a harvesting device 1 with two endless conveyors 4, 5, the conditions are mirror-symmetrical, so that wipers 33 are arranged to the left and right of the inlet opening 6, which extend mirror-symmetrically from their brackets 34 in the direction of travel F and approximately parallel to a vertical median longitudinal plane of the vehicle, so that the openings 40 are also approximately parallel to the longitudinal plane of the vehicle. The wipers 33 can be pivotably arranged on the brackets 34, so that the former can be pivoted away from the chain links 14, 15 for cleaning or maintenance purposes, for example. Moving to the functional position, in which the front end regions 38, 39 of the broaching elements 36, 37 are held closely spaced (0.5 mm to 4 mm) in front of the front surfaces 21, 22 of the chain links 14, 15 can then be effected by spring loading and use of - if necessary adjustable - stops to secure the minimum distance. Alternatively, the holder 34 of the wipers 33 can also be designed to be fixed.

According to the exemplary embodiment, a second clearing element 41 is arranged behind the clearing element 36, which can pick up crop residues carried by the upper holding means 18 and can lead through the openings 40 to the outside. This second clearing element 41 is placed closer to the deflection path of the chain links 14, 15 than the front clearing element 36 or 37, which with its rear end forms a guiding function of the crop 3 in the direction of the inlet opening 6.

Between the broaching elements 36 and 37 or between the lower broaching element 36 and the shear bar 31, the holding means 17 or the drivers 32 run in such a way that they cooperate at a close distance with the broaching elements and the latter strip off the crop. The same applies to the holding means 18, which run in in the upper region between a cover plate 42 and the clearing element 37. 7 to 9 show cleaning devices 47 which are assigned to a rear side of the respective conveyors 4, 5 facing away from the working run 4a, 5a (FIG. 2) and with their cleaning members 48 the cutting means directed outwards parallel to their direction of rotation U1, Cover U2. The direction of rotation of the cleaning members 48 therefore corresponds to the arrow R. In the exemplary embodiment, the cleaning device 47 is arranged in the region of a deflection wheel 60 for the conveyor chain 4, 5. A similar cleaning device 47, as shown here for the cutting means 16, can also be provided for holding means 17 and / or 18, but the main contamination from corn leaves or other long-fiber crop components will affect the angled cutting knives 16.

According to the exemplary embodiment, each cutting means 16 is swept by at least one cleaning member 48 of the cleaning device 47 in the same direction as its direction of movement U1 or U2, so that crop residues 61 which have accumulated are pushed out of the angle of the protractor 16 from behind.

It is understood that such a cleaning device 47 can in principle also be used with conveyor drums or other conveyors. The cleaning device 47 with its cleaning members 48 sweeps over the cutting means 16 both on the top and on the underside, with a close spacing of the sweeping being provided. The cleaning members 48 can either be rigid parts, for example made of steel or synthetic material. fabric, or be designed as rotatable brushes or the like flexible displacement means. In any case, the cleaning means 48 rotate about an axis of rotation 49 perpendicular to the planes S, H1, H2. In the case of rotating brushes or similar flexible displacement means, for example also sponges, felt mats, rubber lips or the like, a touching sweep of the cutting means 16 or Holding means 17, 18 may be provided. In any case, contactless painting at a close distance is also possible, which is used in particular with rigid cleaning members 48.

The cleaning members 48 have a substantially triangular shape which tapers outwards so that their tips come close to the deflection shields 21 and there cause intensive clearing on the edges facing these between the cutting means 16 and the deflection shields 21.

It is provided in the present exemplary embodiment that a plurality of cleaning members 48 are arranged in a star shape around the axis of rotation 49. Instead of this, it is also possible that only individual, possibly only the cutting means 16 or the holding means 17 or 18, either only overflow or only underflow cleaning members 48 are provided.

7, the cleaning device 47 is connected via a belt drive 51 to the deflection wheel 60 and can be driven by its rotation, so that no separate drive for the cleaning device 47 is required. In one particular advantageous embodiment (FIG. 12), a shaft 62 is guided out of the frame 10 or 11 to the rear of a main gearbox, which is located axially below the drive or deflection wheel 60, the shaft 62 below the revolving plane of the conveyors 4, 5 is arranged. As a result, the surface of the frames 10, 11 which carry the conveyors 4, 5 is to be formed with a smooth surface, and there is no shaping as would be required to cover a belt drive 51 according to FIG. 7. A step or the like on the surface that would disrupt the course of the funding is therefore not necessary.

These spatial conditions are particularly favorable, the drive for the endless conveyor 47 can be arranged in unloaded areas and without disturbing the functionality. The shaft 62 has a V-belt pulley, from which an additional drive for a roller 63 with a worm gear of a laterally arranged stalk and plant divider is removed. The transmission for the drive or deflection wheel 60 and the drive for the cleaning device 47 are forcibly synchronized with one another by the exemplary embodiment shown, so that further synchronization measures are unnecessary.

The star body 50 carrying the cleaning members 48 is held on the standing axis of rotation 49 by means of a clamping connection 64, which is particularly advantageously designed as a safety coupling, ie that damage to the cleaning members 48 is avoided when stones are caught in the conveyor chains 4, 5 because do not continue to rotate them with the shaft, but then release them from their rotation. A separate motor 62 for the cleaning device 47 can also be provided (FIG. 8). This motor can be a hydraulic one, for example.

Then the cleaning device 47 can be driven independently of the rotational speed of the conveyor 4, 5. With a rotational speed of the cleaning device 47 which can be set independently of the rotational speed of the conveyors 4, 5, it is possible to adapt to different degrees of contamination (for example dry or moist soil).

In any case, it is particularly expedient to keep the rotational speed of the cleaning device 47 about the axis 49 greater than the rotational speed of the conveyor 4, 5. A plurality of cleaning members 48 can then sweep over a cutting means 16 or holding means 17, 18 and thus effect particularly thorough cleaning. The ejection effect is also supported. The ejection range of the removed sheet or fiber parts 61 is increased.

The sequence of movements of the cleaning process is shown in FIG. 9.

The rotational speed of the cleaning device 47 is preferably two to five times the value of the rotational speed of the endless conveyors 4, 5.
