Description

The invention relates to an agricultural combination device for cultivating the soil with the ground up or down. breaking tool as well as a packer and crumbler roller working behind it, which with in radial planes of Roller arranged rows of teeth penetrates the soil, and with a seed discharge device, which is in front of the packerund Has arranged seed discharge pipes.

Agricultural combination devices are known with different tooling and offer the The advantage of being able to work the soil with a single crossing at a time.

Various ways of arranging seed discharge devices are known. For example, can a seed drill can be arranged on the frame of a tine rotor arranged as part of the combination device, wherein the seed discharge pipes are arranged behind a cover that shields the tine rotor from the rear, which, if necessary, can also serve or is arranged to smooth out the earth thrown up by the tine rotor. Accordingly, the seed then falls on the more or less smooth top of the soil, which is then removed from the Krümlerbzw. Packer roller is solidified with partial crumbling.

Accordingly, the seed is introduced into the soil at a comparatively shallow depth and / or only from a loose one Layer of crumbs covered. This arrangement is advantageous for the application of such seeds, which in comparatively should germinate shallow soil.

As far as the seeds are planted deeper in the ·, .Jen should / are expediently seed coulters at the outlet pipes arranged, which cut into the ground and the outlet openings able to keep the outlet pipes at a level below the top of the floor.

Sufficient space must be provided for the arrangement of the discharge pipes between the tine rotor and the packer and crumbler roller be present, which brings a relatively large length of the entire device with it. While this is for that The result of the work is irrelevant, but it can make the device more difficult to use, for example if the Device by means of three-point linkage or the like. is arranged directly on a towing vehicle and for turning maneuvers or must be lifted from the towing vehicle for road transport. This is effective with a long device Device weight on the towing vehicle with a comparatively large lever arm, with the result that the front axle lighter towing vehicles is unloaded or even lifted off the ground.

In order to ensure that the center of gravity of the raised combination device is as close as possible behind the towing vehicle lies, it is known from the unpublished European patent application (Az. 85105556.6), the packer and To arrange the crumbling roller immediately behind the tine rotor, in such a way that the roller forms a baffle for the tine rotor thrown earth current forms. However, because of the spatial constraints, there are two tine rotors and crumblers and Packer roller, a possibly provided seed drill is arranged behind the packer and crumbler roller. This seeder can shift the center of gravity accordingly from the working position behind the packer and crumbler roller by means of a separate lifting device in a transport position above the packer and crumbler roller or of the tine rotor are raised. Because of this construction, the combination device can also be compared with light towing vehicles are used, but the construction is complex overall.

Therefore it is the task of the invention! a combination device of the type indicated at the outset, which is structurally simple and has a construction that is as short as possible Allows arrangement for the application of the seeds, in fact 5 in such a way that the seeds are as constant as possible and reproducibly predeterminable depth below the top of the worked soil are introduced into the same can.

10 This object is achieved in that the seed discharge pipes each opening into the spacing between adjacent rows of teeth and the packer and crumbler roller tight behind the opening or breaking tool as a baffle surface in the earth flow generated by this tool.

the packer and crumbler roller removed. The combination device according to the invention can accordingly also have such areas work trouble-free, on which long-stranded vegetation is left behind after the harvest in order to be able to use the humus formation associated with the rotting of this property.

In principle, different types of opening or breaking tools can be arranged in front of the packer and crumbler roller such as coulter tools or power harrows. With regard to particular constructive simplicity and For a good work result, however, a tine rotor is preferred, which runs in the direction of travel that supports the device is drivable. If the rotational speed is sufficient, the rotor only needs a few prongs, preferably only one prong in each case in radial planes of the rotor axis that are comparatively far apart from one another, to be stocked. Due to the low number of tines, long-stranded plant matter cannot adhere to the tine rotor, rather, it is effectively torn apart. At the same time, the soil is due to the relatively high speed of rotation effectively worked through without the risk of complete peeling of the processed soil layer from the Subsoil exists. Rather, there remains a bond between the subsoil, which is desirable with regard to the risk of erosion and the soil layer worked by the rotor.

According to a particularly preferred embodiment of the invention it is provided that the end pieces leading to the outlet openings of the seed outlet pipes are approximately tangential are aligned or alignable to the roller axis and / or the outer ends of the teeth in the axial view of the roller over the outlet mouths or the end pieces in Radiairich ^ device protrude with respect to the roller axis. This will be

the seed discharge pipes particularly effective from adhering Freed soil or strands of plants.

The packer and crumbler roller is expediently included a substantially closed circular cylindrical jacket and rows of teeth welded onto it. This design only remains comparatively even on wet floors little soil hang on the circumference of the waizen. In addition, between the rows of teeth in particularly simple Way on the side of the roll facing away from the seed discharge pipes, scrapers can be arranged, which is preferred with a small ground clearance below a ground-parallel plane penetrating the roller axis. rest against the roller. With this arrangement, the layer of earth that may stick to the ground during work is immediately removed stripped behind the contact zone between the floor and the roller. Accordingly, the from a small height falling earth has practically no effect on the work result left by the combination device.

Another preferred embodiment of the invention is characterized in that the opening or breaking Tool or the tine rotor in a strip-like manner, leaving behind several adjacent ones in the transverse direction of the device Unprocessed soil strips work, the seed discharge pipes only within the processed soil strips are arranged and the roller is recessed or reduced in the area of the unprocessed floor strips Diameter and / or is arranged without rows of teeth. Since the unprocessed strips of soil in their through Vegetation and the like good protection against erosion is achieved because the soil in the worked strips is less easily washed away by rain

The combination device according to the invention is essentially with a tine rotor 10, in front of which coulter tools 60 are arranged in the area of the tracks of a towing vehicle can, a packer and crumbler roller 20 and a seed Aust:

equipped.

5 seed discharge device 30 with seed discharge pipes 31

The tine rotor 10 has a frame which essentially by a transverse bar 1 and at the ends of which are arranged side parts 3, on which the tine rotor is stored. The transverse beam 1 in turn consists of two beam parts 1 · and 1 ″, the one on both sides of the beam parts connecting supporting housing 2 are arranged for a transmission, which via a PTO shaft 4 with a PTO connection of a towing vehicle, not shown, is drive-connected and its output shaft in housed a beam part 1 'and via a drive transmission arranged in the associated side part 3, such as a chain Or the like., With the tine rotor 10 to drive it in one the direction of travel of the device supporting the direction of rotation is coupled. On the crossbeam 1 is a bracket 5 above of the gear housing 2, to which a three-point linkage 6 can be connected, with which the device is liftably connected to a towing vehicle, not shown. A fixed extends between the side parts 3 arranged, on the lower legs of the bracket 5 additionally supported support beam 7, the for the arrangement of the coulter tools 60 serves. Furthermore, between the side parts 3 above the tine rotor 10 there is one for stabilization of the side parts 3 preferably supporting cover 8 arranged, which the tine rotor essentially only after

at the top and, if necessary, also partially shielded towards the front for safety reasons, but only covered towards the rear as far as is necessary for reasons of splash protection.
A special feature of the frame of the tine rotor 10 is that the axis of the tine rotor 10 is arranged in front of the transverse beam 1 in a side view of the device. In this way, on the one hand, power take-off shafts 4 of normal length can be arranged between the towing vehicle (not shown) and the transmission accommodated in the housing 2; on the other hand, a relatively short overall length of the combination device is achieved because the space below the power take-off shaft 4 is also partially used for the tine rotor 10.

The packer and crumbler roller 20 has its own roller support frame 23, which consists essentially of side arms 24 and a frame cross member connecting the same H-shape 25 exists. With their one ends, the side arms ^ 20 24 are pivotable about a transverse axis of the combination device the side parts 3 of the frame of the tine rotor 10 mounted. At the opposite ends of the side arms 24 is the Axis of the packer and crumbler roller 20 mounted. Accordingly, the roller support frame 23 is on the frame of the tine rotor 24 attached in the manner of a longitudinal rocker.

On the frame cross member 25, a central arm 26 is fixedly arranged which by means of a length-adjustable telescopic support 27 is connected to the bracket 5. The length of the telescopic support 27 set in each case, the position of the Roller support frame 23 is specified relative to the frame of the tine rotor 10. This simultaneously adjusts the height of the Tine rotor 10 is determined because its frame is floating during soil cultivation by means of the three-point linkage 6,

- 15 -

i.e. connected to the towing vehicle so that it can move in height and, accordingly, the weight of the tine rotor 10 as well its frame via the telescopic support 27 and the roller support frame 23 on the packer and crumbler roller 20 is supported.

The telescopic support 27 is expediently designed with play, in such a way that the tine rotor 10 and its frame are optionally opposite the packer and crumbler roller when the rotor tines hit stones or the like. can lift something without the packer and crumbler roller executing a corresponding vertical movement at the same time.

The packer and crumbler roller 20 has a substantially closed, circular-cylindrical jacket 22, on which teeth 21 are arranged in rows in radial planes of roller 20 are arranged.

The teeth 21 have a parallelogram-like shape with parallel, straight leading and trailing edges of the same type Length as well as circular inner and outer edges, the circular arcs of the last two edges mentioned have the same radii of curvature. This means that the teeth can be cut out of a sheet metal without waste. Since the rear edge of the teeth 21 pointing against the direction of rotation of the roller 20 with the jacket 22 of the roller 20 encloses an acute angle, the roller moves over the soil to be worked by the in the soil surface penetrated teeth 21 rotated without the risk of slipping.

As shown, there remains between ch & j * «consecutive Teeth 21 of a row each free a gap, the size of which corresponds approximately to the size of the teeth 21. By the way, they are

-Ί6 · '-

Teeth of adjacent rows of teeth are arranged offset from one another, so that in each case one tooth 21 of the one row is arranged next to gaps in the adjacent rows of teeth.

The packer and crumbler roller 20 is arranged immediately behind the tine rotor 10, which accordingly throws the soil it has grasped against the facing side of the packer and crumbler roller 20 according to the arrow P. The roller 20 _v thus forms an impact surface in the £ 10 from the tine rotor

generated and thrown up earth current, which due to the |

Rotation of the packer and crumbler roller 20 especially when the device is traveling over the soil to be worked is effectively steered downwards. Since the impact surface formed by the packer and crumbler roller 20 is constantly moving is, on the one hand, a good comminution of coarser pieces of earth thrown up by the tine rotor 10 and the like Teeth 21 reached, on the other hand, the earth current acts constantly - comparable to a sandblasting fan - in the sense of a Cleaning of the shell 22 of the packer and crumbler roller 20, i.e. soil adhering to the roller 20, is constantly carried out replaced the earth current.

Since scrapers 40 may also be arranged on the packer and crumbler roller 20, this can also be done with very moist and loamy soils with a constantly practically completely cleaned packer and crumbler roller 20 and a correspondingly good effect of the roller 20 can be expected.

The seed discharge device 30 is supported on the transverse bar 1 of the frame of the tine rotor 10 and on the bracket 5. This has a seed container 34 with a mechanical or pneumatic distribution ^{device which distributes the]} seeds to a plurality of feed lines 33,

which in turn lead to seed discharge pipes 31 with outlets 32 lead. The seed outlet pipes 31 or their outlet mouths 32 having end pieces are tangential to the axis of the packer and crumbler roller 20 in each case within of the spacing between adjacent rows of teeth 21 of the roller 20, the outlet openings 32, as in FIG. 2 is shown, relatively far below approximately in the area of the underside of the roll shell 22 tangentially touching can be arranged parallel to the floor plane. Such a deep, possibly even deeper arrangement the outlet openings 32 is possible because the seed outlet pipes 31 or the lower ends thereof only in the areas raised by the tine rotor 10 when the device is working on the ground Earth current, but not protrude into the solid ground below the soil layers worked by the tine rotor 10. The intention of the earth current can be compared with that of a pulpy liquid, i.e. that of the Tine rotor 10 thrown earth flows around the seed discharge pipes 31 or their lower ends and flows on the Tine rotor 10 facing side of packer and crumbling roller 20 towards the bottom, additionally supported by the rotational movement the roller 20. Accordingly, the seed is from the seed discharge pipes 31 in or under the same Brought around the earth flow and covered with a layer of earth, which is due to the work of the packer and crumbler roller 20 is solidified immediately. It is particularly advantageous that the seeds are not caught by the teeth 21 and are undesirable deep ground zones can be indented. Rather, the teeth 21 effect due to their relatively wide penetration in the soil only that the worked soil is well connected to the subsoil and due to the Teeth 21 left behind and the crumb formation promoting holes is well ventilated. It is also advantageous that no long-stranded plant matter on the seed outlet pipes 31

- Ϊ8 -

or the like. can get stuck. This is namely in the Usually washed away by the earth current. The earth current can at least one end piece of each plant strand to rinse in the area of action of a row of teeth 21 and / or under the roller 20, so that the roller 20 the can pull the entire strand away from the seed discharge pipes 31 as the device continues to travel above the ground. In addition, the rows of teeth 21 passing laterally of the seed discharge pipes 31 also act next to the earth flow in the For the purpose of cleaning the outside of the seed discharge pipes 31.

If necessary, several, for example two each, seed discharge pipes 31 can be connected via a common feed line are supplied with seeds. For this purpose, each of the two seed discharge pipes 31 are Y-shaped at their upper ends Interconnected in the manner of a Y-pipe and connected to the respective supply line 33. With sufficient symmetrical design of the Y-shaped connection or the Y-pipe, the incoming seeds with practical negligible scatter distributed over the two seed discharge pipes 31 in each case.

In addition, the seed discharge pipes 31 are preferably adjustable in height arranged. The seed discharge tubes 31 are for this purpose at their upper areas on one in transverse direction of the device extended angle profile 35 attached. Threaded plates 36 are arranged at the outer ends of this angle profile 35, in the threaded bores threaded spindles 37 are used, which are located with their lower ends on the frame cross member Support 25 of the roller support frame 23. In addition, 35 are arranged in the area of the outer ends of the angle profile Saatauslaufrohre 31 slidably received in pipe pieces, which in turn on the Rahrnen cross member 25 of the

Roller support frame 23 are attached. For example, can two pipe sections 38 each be welded to an elbow 39, one of which between the pipe sections 38 extended leg by means of a frame cross member 25 of the roller support frame 23 U-shaped encompassing bracket screw 28 is attached to the frame cross member 25. The other leg the elbow has a bore from the threaded spindle 37; which at least sls rsäi & ilscies' for the spindle 37 is used. If necessary, this leg can also be used for the axial mounting of the respective threaded spindle 37 "serve by a washer is arranged on the threaded spindle on both sides of this leg and the Threaded spindle on the faces facing away from each other of these washers of split pins or the like. with sufficient Length transversely to the spindle axis is enforced.

By adjusting the threaded spindle 37, the angle profile 35 can be moved together with the seed outlet pipes attached to it 31 adjust in height. 20th

Wipers 40, as shown in FIG. 5, are preferably arranged on the packer and crumbler roller 20.

To hold the frame cross member 25 of the roller support frame 23 multiple bow-shaped flat parts 45 be welded, which the packer and crumbler roller 20 in the circumferential direction partially comprehensive in each case between adjacent rows of teeth 21 are arranged. Accordingly, these bow-shaped flat parts only need 45 in the axial view of the roller to protrude little or not at all over the radially outer edges of the teeth 21. To stabilize the flat parts are the same near their free ends by a transverse ribbon 46 welded to them with each other tied together. The flat parts 45 form a basket-like or grid-like cover of the packer and crumbler roller 20, which is accordingly shielded against unintentional contact by people.

- 20 -

A threaded piece 47 is welded to the free ends of the bow-shaped flat parts 45, in which

Threaded hole an adjusting screw 44 is inserted / g

which serves to push the scrapers 40 against the jacket 22 of the packer and crumbler roller 20.

! The wipers 40 are each made of a trapezoidal piece of sheet metal, the narrower end of which with the roll shell 20 cooperating wiper plate 41 forms, while the adjoining wider area with the formation of a U-profile 42 which is open towards the adjusting screw 44 and which forms a scraper handle,

. is folded. The free end of the U-profile 42 engages *

each U-shaped the associated free end of one of the

bow-shaped flat parts 45 and is on it by means of a _%

Bolt 48 pivoted. The U-shaped enclosure of the end piece of the bow-shaped flat part 45 is a causes very stable storage secured against movement in the transverse direction of the device. Incidentally, the U-profile 42 protects the thread of the adjusting screw 44 partially received therein against contamination. Accordingly Adjustment of the adjusting screw can be made without undue effort even after prolonged use of the device be made.

The scraper plates 41 are somewhat narrower than the distance between adjacent rows of teeth 21 of the packer and crumbler roller As a result, only a comparatively low resistance is opposed to the scraper plates 41 when on the roll shell 22 adhering earth is peeled off. At the same time, sufficient cleaning of the roller 20 is achieved.

The spaced from the holding stem 61 vertical rear edge of the deflector part 65 has multiple, for U-shaped recesses which are open towards the holding stem 61 and which are used to receive the front area or the tip 68 a curb shaped like an arrow-shaped wing 69 serve. The coulter blade 69 in turn is on a sleeve-like surrounding the holding shaft 61 in a U-shape Part 70 is arranged, which can be clamped on the holding stem 61 by means of a screw connection 71. This screw connection penetrates an opening, which is through a U-bracket welded on the back of the holding stem 61 is included. Accordingly, when the screw connection 71 is installed, the coulter blade becomes captive on the holding post 61 held. When the screw connection 71 is loosened, the coulter blade around the tip 68, which is in one of the U-shaped Recesses on the back of the deflector part 65 is received in the manner of a hinge joint, for adjustment the angle of attack of the coulter blade 69 can be pivoted. A set screw 73, which on the dem Deflector part 65 facing side of the sleeve-like part 70 is arranged and in the direction of the holding stem 61 through Screwing can be advanced, the pivoting way down.

When working on the ground, the crash bar 74 has the effect of dö.ß over the deflector part 65 or its plate 66 sliding up long-stranded plant matter through the pushing, earth that has also been pushed upwards is thrown forward along the crash bar 74. This avoids that on the Haltestielep 61 stringy plant material can get caught.

The crash bars 74 can be arranged regardless of whether the coulter tool 60 is with or without a coulter blade is used.

In the case of the device described above, it was assumed that the floor is of the same type over the entire width of the device is processed.

In a departure from this, however, it is also possible to only place the floor on parallel strips that run in the transverse direction of the device lying next to each other, to be processed and to leave the strips in between practically unprocessed. One Such processing can be useful for row crops as well as in areas that are highly prone to erosion or very humid be. The unprocessed soil strips and the vegetation on them protect nllm.l "the processed soil strips from attacks by wind and rain. In addition, these unprocessed strips of soil ensure that moist fields'

In order to enable the strip-shaped cultivation described above, the tines of the tine rotor 10 are accordingly Arranged in groups, i.e. between every two groups of tines, one remains in the axial direction of the tine rotor free space corresponding to the width of the strip of flooring that is not to be worked on. In addition, the Packer and crumbler roller 20 cut out in the area of the strips not to be processed, or with a reduced diameter and / or arranged without teeth. Otherwise, the Saatauslau :: tubes 31 are only within the worked soil strips available.

If necessary, according to FIG. 2, instead of the seed discharge pipes arranged in front of the packer and crumbler roller 20 31 or, in addition to the seed discharge pipes 31, also behind the roller 20, seed coulters 80, optionally combined with resilient! harrows 81 be arranged.

The seed discharge pipes 31 are particularly suitable for flat Seeds to be introduced into the soil, in particular seeds from catch crops, for example rapeseed or others Plants for green manure. In addition, the seed discharge pipes 31 can also advantageously be used for sowing Grains are used when a so-called broad sowing, i.e. a planting with very close plant spacing is desired. The coulters 80 are particularly suitable for so-called drill sowing, in which the seeds are proportionate deep in the ground in spaced rows. With the combined discharge of different Seeds, the seeds for the useful plants are usually introduced into the soil via the coulters 80, while via the seed discharge pipes 31 preferably fast and low-growing plants are sown, on the one hand protect the crops during their first growth phase, in particular from attack by the wind, and on the other hand counteract soil erosion. Grasses, for example, are suitable as plants with such a protective function.

In principle, however, it is also possible to sow the main or useful crop by means of the seed discharge pipes 31 and to bring the seeds for fertilizer or protective plantings into the soil via the coulters 80.

In Fig. 10 a modified roller support frame 23 is shown, the harrow 81 on a crossbar of the Frame 23 behind the packer and crumbler roller 20 in the direction of the arrow H are arranged so that they can be swiveled upwards, in such a way that the harrow 81 in the folded-up position is one position above the roller 20 occupy. In addition, instead of seed coulters

On the other hand, the cover plate 9 can be used to adapt the earth flow to different roller diameters If the combination device is put together from different individual elements.

Special embodiments are shown in FIGS. 11 to 14 the rotor tines 11 are shown. They have the same as well like the normal tines of the rotor 10, which can be seen among other things from FIG. 3, each one arranged on the rotor shaft Holding arm 13, in which the actual soil cultivation tool representing Zinkenendstück 14 is used interchangeably. The longitudinal axes of Holding arm 13 and prong end piece 14 one in the direction of rotation ü of the tine rotor 10 open obtuse angle, so that a with the axis of the Zinkenendstückes 14 coinciding straight line extends at a radial distance from the axis of the rotor shaft.

The prong end pieces 14 have a substantially square cross-section and are arranged such that |

that in each case one longitudinal edge of the prong end piece 14

The special feature of the rotor tines 11 in FIGS. 11

to 14 now consists in the fact that at the free end of the prongs |

end pieces 14 each have a cutting blade 12, preferably in the form of short wings arranged in the shape of an arrow (cf. * Fig * 12) | is arranged. The cutting blades 14 are arranged with a gate effect, i.e. in an axial view of the ,,

Tine rotor 10 forms one of the axis of the rotor shaft |

out to the connection area between the tine end piece 14 and cutting blade 12 extending radial ray R with the plane formed by cutting blade 12 one in the circumferential direction tung U open obtuse angle ^. Accordingly, | the cutting blade 12 to lift the detected earth slightly when it is introduced into the ground (first cut effect).

In the embodiment illustrated in Figures 11 and 12 embodiment, the cutting blades 12 extend in the remaining ¹ I parallel to the axis of the rotor shaft. *

In the case of the tines shown in FIGS. 13 and 14, the axis of the rotor shaft runs inclined to the cutting blades 12. In addition, the prongs are preferred in pairs diametrically opposite one another with respect to the rotor shaft with mutually approximately parallel pairs Cutting blades 12 arranged. In addition, the prongs of a pair are preferably somewhat in the axial direction of the rotor 10 offset to each other. The rotor tines 11, which each form a pair of tines or are arranged as a double set, produce with their cutting blades 12 accordingly in the ground

a working horizon with a roof-shaped profile «This enables, for example, the seeds through appropriate Arrangement of the oil outlet pipes 31 and coulters 80, respectively to be introduced in the area of the ridge line of the roof-shaped profile, while the same fertilizer is fed to the side can be.

In general, the cutting blades 12 increase independently on the type of their arrangement on the tine end pieces 14 the width effect of the rotor tines; In addition, stringy material such as remains of roots is found in the soil or the like., cut up. Because of this effect of the cutting blades 12, it is sufficient to have the rotor 10 with only a few prongs to equip, for example, between tines or pairs of tines that are mutually aligned in the axial direction of the tine rotor 10 are adjacent, there may be distances of the order of half or full diameter of the tine rotor correspond. In addition, there is usually at most one tine in each radial plane of the tine rotor is arranged, so there is an extremely open tine arrangement, which is also advantageous for this reason, among other things is because practically every possibility is ruled out that long-stranded goods are attached to the prongs or the Rotor shaft can devour. Finally, the cutting blades 12 offer the further advantage that they rotate when the rotor In the direction of travel supporting the direction of rotation ü increase the propulsion caused by the tine rotor 10.
