SELF-PROPELLED COMBINE HARVESTER

Description

[0001] The present invention relates to a self-propelled combine harvester according to the preamble of claim 1.

[0002] A self-propelled combine harvester is known from DE 21 22 402 A1. DE 21 22 402 A1 describes a collection container, a so-called stone trap, located below the intake channel. The stone trap is designed as a one-piece container that can be removed as a whole from the combine harvester's frame. For this purpose, strips are attached to the frame below the transition area between the intake channel and a downstream threshing unit; these strips extend across the width of the intake channel. The collection container fits snugly against these strips.A deflector plate, angled at one end, is located on the underside of the intake chute. This plate deflects stones conveyed in the intake chute towards the collection container and simultaneously prevents unwanted grain from escaping the combine harvester. The angled section of the deflector plate overlaps the correspondingly angled front wall of the collection container. A disadvantage of this combine harvester is that, firstly, the stone trap must be completely removed for emptying, meaning the operator is burdened by both the weight of the trap itself and its contents. Secondly, the upward-extending front deflector plate of the stone trap limits the swivel range of the intake chute.

[0003] DE 39 14 962 A1 discloses a combine harvester with a maintenance opening located above the intake channel, through which the front threshing concave segments of the threshing unit can be removed. The combine harvester known from DE 39 14 962 A1 also has a stone trap. Removing the threshing concave segments through the maintenance opening located above the intake channel is complex, as the threshing concave segments must be guided past the threshing drum.

[0004] EP 1 530 895 B1, EP 2 294 909 B1, DE 692 14 072 T2 and EP 0 516 892 B1 also disclose combine harvesters with stone trap troughs whose walls can be at least partially folded down to provide access to the threshing concave segments.

[0005] Based on the aforementioned prior art, the invention aims to further develop a self-propelled combine harvester of the type mentioned above, which is characterized by a more maintenance-friendly design.

[0006] This problem is solved according to the invention by a self-propelled combine harvester with the features of claim 1. Advantageous further developments are the subject of the dependent claims.

[0007] According to claim 1, a self-propelled combine harvester is proposed, comprising a feed chute height-adjustable by actuators, a threshing device downstream of the feed chute, which has at least one threshing drum and at least one threshing concave sectionally enclosing the threshing drum, and a collection container arranged below the feed chute in the transition area between the feed chute and the threshing device, into which foreign bodies conveyed along with the feed chute can be separated in a collection position of the collection container, wherein the collection container can be removed from the transition area in the direction of travel.According to the invention, the collection container is arranged to pivot about a horizontal pivot axis extending transversely to the direction of travel below the collection container from the collection position to a maintenance position, in which the collection container essentially completely releases its installation space, so that after pivoting into the maintenance position, the collection container reveals a maintenance opening formed therein for removing at least one front threshing concave segment of the threshing concave.

[0008] The key is that by swiveling out the entire collection container, the largest possible maintenance opening is released without having to completely remove the collection container.

[0009] In particular, the collection container, in its collection position, can rest at least on its bottom on horizontal support segments arranged or formed on opposing lateral supports, which extend section by section transversely to the direction of travel. Resting on its bottom means that the collection container rests at least with its bottom on the lateral supports. The lateral supports are preferably arranged on the inner surfaces of opposing side walls of a housing surrounding the threshing device. The supports are designed as essentially planar components, so that they have only a small axial extension transversely to the direction of travel.

[0010] The brackets can also serve a sealing function. For this purpose, a circumferential seal, corresponding to the outer contour of the collection container, can be attached to the brackets, starting from the respective support segment. Together with the circumferential seals, the brackets allow for tolerance compensation in the transverse direction of the combine harvester. At the same time, the collection container can be reliably sealed against free-flowing grains, i.e., grains sliding past the side walls of the collection container.

[0011] According to a further development, the collection container can have a front flap that can be operated by a single lever and pivoted into an open position around a pivot axis located between the side walls of the container, towards the intake channel. Compared to the previously mentioned prior art, this offers the advantage that emptying the collection container can be done with one hand simply by pivoting the front flap. This makes the emptying process more ergonomic. Furthermore, unlike the prior art, it eliminates the need to completely remove the collection container for emptying.

[0012] Preferably, a guide plate extending across the width of the collection container can be pivotably arranged on the flap pivot axis, the free end of which is guided by at least one guide element reversibly detachable on the underside of the intake channel in order to follow the movement of the intake channel during height adjustment.

[0013] In particular, the front flap can be locked in the open position on the transfer plate. If the feed duct is moved for height adjustment with the front flap open, a collision between the two assemblies is prevented because the open front flap, locked to the transfer plate, follows the movement of the feed duct together with the transfer plate.

[0014] Furthermore, two opposing consoles can be arranged on the edge of the front flap, in which a shaft running parallel to the flap pivot axis is rotatably mounted, on which the operating lever is rotatably arranged, and a lever arm can be arranged non-rotatably on the shaft, which transmits a pivoting movement of the operating lever to the shaft by means of a driver arranged on the operating lever.

[0015] For this purpose, the operating lever may be provided with a first, shorter lever section and a second, longer lever section, wherein the first lever section extends from the shaft in the direction of the flap pivot axis and the second lever section extends from the shaft in the opposite direction. In particular, the second lever section projects beyond the front flap, so that a sufficiently long lever arm is provided to allow the front flap to be operated, especially with one hand.

[0016] Furthermore, the first lever section can have a beveled contact surface facing the front flap, with the inclination of the contact surface increasing from the shaft to the outer end of the first lever section. This gives the operating lever a defined pivoting path before the contact surface rests against the front flap, thus transmitting a force applied by the operating lever to the shaft.

[0017] In particular, a spring-loaded locking element can be axially displaceable on the guide plate at its leading edge facing away from the flap pivot axis. This locking element engages with the operating lever in the open position of the front flap. This has the advantage that when the feed duct moves, the front flap and the guide plate can follow the movement, thus preventing accidental collisions, especially when lowering the feed duct.

[0018] Preferably, a lever arm with a hook-shaped end section can be arranged at at least one free end of the shaft adjacent to the respective bracket. When the front flap is closed, this lever arm engages in an opening of a mounting tab located on a side wall of the collection container, thus locking the front flap in the closed position. Preferably, such a lever arm can be arranged at each of the two free ends of the shaft.

[0019] Preferably, the console arranged adjacent to the operating lever can have a section running essentially parallel to the second lever section, on which a tension spring acts at its end and which, with its opposite end, acts on a component arranged between the console and the operating lever in a rotationally fixed manner on the shaft.

[0020] In particular, two pivot levers can be hinged opposite each other on the side walls of the collection container in the base area, allowing the container to pivot around the pivot axis. This allows the collection container to be held in the maintenance position after it has been moved into that position. Complete removal of the collection container, as required by the prior art, is not necessary.

[0021] According to further training, the collection container can be detachably connected to the side supports by means of fastening devices, in particular screw connections.

[0022] In particular, to pivot the collection container into the maintenance position, the collection container may first have to be moved into the open position, followed by loosening and removing the fastening means and at least one guide element, so that the collection container can be moved out of the side brackets in the direction of travel and pivoted section by section around the pivot axis until the collection container rests against a stop arranged below the pivot axis on a wall section of the combine harvester.

[0023] The present invention is explained in more detail below with reference to an embodiment illustrated in the drawings.

[0024] They show: Fig. 1 a schematic representation of a self-propelled combine harvester in side view; Fig. 2 a schematic and exemplary perspective view of a collection container in an unlocked closed position; Fig. 3 a schematic and exemplary perspective view of the collection container after Fig. 2 in an open position; Fig. 4 schematically and by way of example a sectional view of the collection container in its closed position; Fig. 5 schematically and by way of example a sectional view of the collection container in its open position; and Fig. 6 schematically and by way of example the collection container in its maintenance position.

[0025] Fig. 1Figure 1 shows a schematic side view of a self-propelled combine harvester 1. The combine harvester 1 has a support frame connected to a chassis, on which a multi-part machine housing 2 is mounted. The combine harvester 1 picks up crop 4 from a field in a manner known per se using a header 3 arranged on a feed chute 5, the height of which is adjustable by actuators 19. Reference numeral FR denotes a direction of travel of the combine harvester 1.

[0026] The harvested crop 4 is fed by an inclined conveyor arranged in the intake channel 5 to a threshing and separating unit. The threshing and separating unit comprises a threshing device 6 operating according to the tangential flow principle, a separating device 7 downstream of the threshing device 6, and a sieve arrangement as part of a cleaning device 8 of the combine harvester 1.

[0027] In the threshing device 6, the crop 4 is passed between at least one threshing drum 9 and a threshing concave 10 that at least partially encloses it, and separated into at least two partial streams. The first partial stream separated by the threshing device consists essentially of grains, short straw, and chaff and is fed via a preparation floor 11 to the cleaning device 8, which comprises an upper sieve 14 and a lower sieve 15. A cleaning blower 16 generates an airflow that passes through the sieves 14 and 15.

[0028] The second partial stream exiting the threshing device 6 at the rear, consisting essentially of straw and residual grain, is directed by a feed drum 13 to the separating device 7, which is designed as an axial rotor 17. In an alternative embodiment, the separating device 7 can also be designed as a straw walker arrangement. A crop flow consisting essentially of a mixture of grains, ear fragments, and short straw is separated by the separating device 7 and transferred via a return floor 12 and the preparation floor 11 to the cleaning device 8.

[0029] In the cleaning device 8, a purified grain stream is finally separated in a manner known per se and fed via a collecting and guide floor 18 to a grain conveyor screw, from where it is conveyed by means of an elevator into a grain tank.

[0030] Below the intake channel 5, in the transition area 20 between the intake channel 5 and the threshing device 6, there is a - in Fig. 1 A collection container 21 (not shown), a so-called stone trap, is arranged into which foreign bodies, primarily stones, conveyed by the inclined conveyor device in the feed channel 5 can be separated when the collection container 21 is in a collection position. The collection container 21 is closed, except for the upper surface facing the transition area 20, through which the foreign bodies enter the collection container 21 when in the collection position.

[0031] In Fig. 2A schematic and exemplary perspective view of the collection container 21 in an unlocked closed position is shown. The upward-opening collection container 21 has a base 22, a rear wall 24, two opposing side walls 23 oriented essentially perpendicular to the base 22, and a front flap 25. The base 22 and the rear wall 24 can be made in one piece, for example, by bending a section of the sheet metal forming the base 22. The front flap 25 is pivotable about a flap pivot axis 26 to allow emptying of the collection container 21 in an open position. The flap pivot axis 26 is hinged to the side walls 23.

[0032] A diverting plate 27, extending across the width of the collection container 21, is pivotably mounted on the flap pivot axis 26. The diverting plate 27 has an arcuate contour and extends section by section from the flap pivot axis 26 towards the attachment device 3. At its leading edge, facing away from the flap pivot axis 26, the diverting plate 27 has a bent section 28. A locking element 29, biased by a compression spring 30, is axially displaceable within the bent section 28. The compression spring 30 can apply a preload to the locking element 29, which positions and holds the locking element 29 in the direction of a vertical recess 31 in the bent section 28.

[0033] Two opposing brackets 32 and 33 are arranged at the edges of the front flap 25. The brackets 32 and 33 can be attached to the front flap 25 by means of screw connections. A shaft 34, running parallel to the flap pivot axis 26, is rotatably mounted in the brackets 32 and 33.

[0034] By means of a single operating lever 35, the front flap 25 can be pivoted into an open position about the flap pivot axis 26, which is articulated between the side walls 23 of the collection container 21, in the direction of the intake channel 5.

[0035] The operating lever 35 is pivotably mounted on the shaft 34. A lever arm 37 is fixedly mounted on the shaft 34, which transmits a pivoting movement of the operating lever 35 to the shaft 34 by means of a driver 36 arranged on the operating lever 35, for example a bolt screwed onto the operating lever 35.

[0036] The operating lever 35 has a first, shorter lever section 38 and a second, longer lever section 39. The first lever section 38 extends from the shaft 34 in the direction of the flap pivot axis 26. The second lever section 39 extends from the shaft 34 in the opposite direction.

[0037] At at least one free end of the shaft 34, adjacent to the respective bracket 32, 33, a lever arm 40 with a hook-shaped end section 41 is arranged. In the closed position of the front flap 25, the hook-shaped end section 41 engages a locking section 63 that projects partially into the interior of the collection container 21 and extends perpendicularly to the side wall 23. Thus, the front flap 25 is locked in the closed position. Preferably, a lever arm 40 with a hook-shaped end section 41 is arranged at each end of the shaft 34. The locking section 63 can be designed as a bolt or the like with a cross-section that is at least partially circular.

[0038] On each of the two side walls 23, adjacent to the front flap 25, a fastening tab 42 is formed or arranged. Each fastening tab 42, extending perpendicularly to the side wall 23, has an opening 43 which allows the passage of a - in Fig. 2 The fastening means 57, not shown, such as a screw connection, serves to detachably fix the receiving container 21 to the housing 50 of the threshing device 6.

[0039] The console 32, located adjacent to the operating lever 35, has a section 44 that runs essentially parallel to the second lever section 39 of the operating lever 35. A tension spring 45 engages at the end of section 44, and its opposite end engages a hook-shaped component 46 that is fixedly mounted on the shaft 34 between the console 32 and the operating lever 35. In the illustrated closed position of the front flap 25, the tension spring 45 exerts a tensile force on the hook-shaped component 46 to secure the shaft 34 and the operating lever 35 mounted on it against unintentional pivoting.

[0040] In Fig. 3 This is a schematic and exemplary perspective view of the collection container 21 according to Fig. 2The front flap 25 is shown in an open position. In its open position, the front flap 25 can be locked against the guide plate 27. For this purpose, the spring-loaded locking element 29 engages section by section in a recess 47 on the second lever section 39 of the pivoted operating lever 35.

[0041] To empty the collection container 21, the operating lever 35 is moved towards the inclined conveyor 5 until the first lever section 38, with its contact surface 48 facing the front flap 35, rests against the surface of the front flap 25. For this purpose, the contact surface 48 of the first lever section 38 is chamfered, with the inclination of the contact surface 48 increasing from the shaft 34 towards the end of the first lever section 38. Pivoting the operating lever 35 until the contact surface 48 rests against the surface of the front flap 25 causes the front flap 25 to be unlocked by means of the rotation transmitted to the shaft 34 via the lever arm 37.

[0042] By further pivoting the operating lever 35, it is inserted into the vertical recess 31 in the angled section 28. In doing so, the operating lever 35 moves the spring-loaded locking element 29 axially until the opening recess 47 on the second lever section 39 is level with the locking element 29. The spring force pushes the locking element 29 axially back into the recess 47, thereby locking the front flap 25 in the fully open position against the guide plate 27.

[0043] To close the collection container 21, the locking element 29 is axially displaced against the spring force, thus unlocking the operating lever 35. The operating lever 35 is then pivoted about the axis of rotation of the shaft 34 in the direction of the collection container 21 until the front flap 25 rests against the base 22 and the side walls 23. In the closed position of the front flap 25, the two lever arms 40 with their hook-shaped end sections 41 engage the respective locking sections 63 on the inner sides of the side walls 23.

[0044] First, the operating lever 35 is pivoted towards the collection container 21 until the lever arms 40, with one of the inclined contact surfaces 62 of the end sections 41 facing the front flap 25, rest in front of the respective locking section. By further pivoting the operating lever 35 towards the collection container 21, the lever arm 40 is pivoted along the inclined contact surface 62 about the axis of rotation of the shaft 34 against the torque applied by the spring 45, until finally the hook-shaped end sections 41 are pivoted behind the respective locking section 63 due to the torque applied by the spring force in order to engage behind it and positively lock the front flap 25.The preload force of the spring 45, which is adjustable in particular, exerts a torque via the lever arm of the hook-shaped component 46. This torque holds the lever arms 40 in the locked position, thus preventing accidental release of the lock. The preload force exerted by the spring 45 can be adjusted by attaching the end of the spring that engages the section 44 to the section 44 at different axial distances from the hook-shaped component 46.

[0045] In Fig. 4 A schematic and exemplary cross-sectional view of the collection container 21 in its closed position is shown.

[0046] The collection container 21, in its collection position, rests at least on its bottom side against the lateral supports 49 arranged opposite each other on the side walls 50 of the housing surrounding the threshing device 6. The supports 49 are designed as essentially planar components, so that they have only a small axial extent transverse to the direction of travel FR. The supports 49 have support segments 60 ( Fig. 6 ) which extend section by section transversely to the direction of travel FR. The supports 49 are shaped according to the contour of the collection container 21, so that at least the bottom 22 rests essentially in a form-fitting manner on the support segments 60 of the supports 49. Seals 51 are arranged on the supports 49 and in the circumferential direction of the collection container 21.

[0047] In Fig. 4The feed channel 5 is shown raised by actuating the actuator 19. To ensure that the guide plate 27 follows the up and down movement during height adjustment of the feed channel 5, the guide plate 27 is guided at its free end by at least one guide element 52 reversibly and detachably arranged on the underside of the feed channel 5. The at least one guide element 52 is preferably designed as a bolt, which is detachably fastened to the feed channel 5 by means of a screw connection.

[0048] The collection container 21 is pivotally arranged below the collection container 21 about a horizontal pivot axis 53 extending transversely to the direction of travel FR. This pivoting action allows the container 21 to be moved from its collection position to a maintenance position, in which it substantially completely vacates its installation space 61. For this purpose, two pivot levers 54 are articulated opposite each other on the side walls 23 of the collection container 21 in the base area, enabling the collection container 21 to pivot about the pivot axis 53. The pivot levers 54 are each articulated at a pivot point 55 on the side wall 50 of the housing surrounding the threshing device 6 and at a pivot point 56 on the side wall 32 of the collection container 21.

[0049] In Fig. 5 The diagram schematically and exemplarily shows a cross-sectional view of the collection container 21 in its connection with the Fig. 3 and 4The described opening position is shown. The inlet channel 5 is fully raised by means of the actuator 19. The transfer plate 27 follows the movement of the inclined conveyor 5 by means of the at least one guide element 52.

[0050] To move the collection container 21 from the open position to its maintenance position, which is in Fig. 6 As shown, the fastening elements 57 and at least one guide element 52 are removed. The collection container 21 can now be removed as shown. Fig. 6 shown in the direction of travel FR, pull out and transfer around the pivot axis 53 below the collection container 21 into the maintenance position, in which a maintenance opening is formed to allow the removal of at least one front threshing concave segment 59 of the threshing concave 10.

[0051] In the maintenance position, the collection container 21 rests against a stop 58 located below the pivot axis 53 on a wall section of the machine housing 2 of the combine harvester 1.

[0052] The collection container 21 designed according to the invention allows the front flap 25 to be operated with one hand. Furthermore, the front flap 25 can be locked in place, thus relieving the operator of the need to hold it during emptying. The positive locking mechanism of the front flap 25 on both sides, provided by the hook-shaped end sections 41, ensures that the front flap 25 remains reliably closed even under heavy loads and thus remains grain-tight. If the feed chute 5 is adjusted in height while the front flap 25 is open, a collision between the two assemblies is prevented because the locking mechanism of the front flap 25 on the guide plate 27 follows the movement of the feed chute 5.Furthermore, the seating of the collection container 21 on the bracket 49 by means of the circumferential seal 51 allows for tolerance compensation in the transverse direction of the combine harvester 1, thereby compensating for manufacturing tolerances and simultaneously ensuring a reliable seal against loose grains.
