Grass shaft of an agricultural harvesting vehicle and agricultural harvesting vehicle
The invention relates to a grass shaft of an agricultural harvesting vehicle and an agricultural harvesting vehicle.
DE 42 15 696 A1 discloses an agricultural harvesting vehicle designed as a self-propelled forage harvester with a chopper and a post-accelerator downstream of the chopper in the crop flow direction of the harvested crop. Either a conditioner or a connecting channel is positioned in the crop flow between the chopper and the post-accelerator, the conditioner being used when the forage harvester processes maize. However, when the forage harvester processes grass, the conditioner is exchanged for a connecting channel. The connecting channel is therefore also known as a grass shaft. According to DE 42 15 696 A1, the grass shaft is positioned between the chopper and the post-accelerator and is held in its position over contact edges and noses. In the case of the glass shaft known from this prior art, there is a risk that the grass shaft will be moved out of its position, which is defined by the contact edges and nose, in particular at high crop flow rates. If the grass shaft is moved to an undefined position, the crop flow is disrupted.
Another harvesting machine designed as a self-propelled forage harvester is known from EP 1 151 654 B1. It is also proposed here that either a conditioner or a grass shaft is arranged in the crop flow between a chopper and a post-accelerator. The grass shaft is mounted on the harvesting vehicle via connections or connecting elements. First connections are designed as screw connections and second connections in the form of quick-release fasteners in the form of clamps. Tools are required to handle the connections and connecting elements, namely for tightening and loosening.
Proceeding from this, the object of the present invention is to create a new type of grass shaft of an agricultural harvesting vehicle and an agricultural harvesting vehicle with such a grass shaft.
This object is achieved by a grass shaft according to claim 1. According to the invention, a clamping lever serving as a fastening device is arranged on at least one side wall of the grass shaft and has an actuating handle at one end and a clamping section at an opposite end, the respective clamping lever being pivotably or tiltably mounted on the grass shaft at a central section positioned between the actuating handle and the clamping section is. The respective clamping lever can be pivoted or tilted between a clamping position and a release position without tools. The grass shaft can be installed and removed without tools via the clamping levers, which have the actuating handle at one end and the clamping section at the opposite end. The clamping levers keep the grass shaft in a defined position, even with high crop flow rates, so that the crop flow through the grass shaft is not impaired.
According to an advantageous development of the invention, the grass shaft has a lock for the respective clamping lever. The locking lever can be held in a defined position relative to the grass shaft via the locking mechanism. This is advantageous for both the installation and the expansion of the grass shaft.
According to an advantageous development of the invention, the grass shaft has a spring for the respective clamping lever, which presses the respective clamping lever into the clamping position. If a spring interacts with the respective clamping lever and presses the respective clamping lever into the clamping position, locking in the clamping position BE2019 / 5273 can be dispensed with. In this case, the locking is then preferably effective only in the release position of the clamping lever.
The agricultural harvesting vehicle is defined in claim 11. Preferred developments of the invention result from the subclaims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being restricted to this. It shows:

The invention relates to a grass shaft of an agricultural harvesting vehicle and an agricultural harvesting vehicle.
The basic structure of an agricultural harvesting vehicle is familiar to the expert addressed here and does not require any further explanation. At this point, for the sake of completeness, it should be pointed out that an agricultural harvesting vehicle, which is designed as a self-propelled forage harvester, has an attachment which is used for separating the harvested crop to be harvested or for picking up be
BE2019 / 5273 already separated crop is used. Starting from the front attachment, the harvested crop can be fed to a chopper of the harvesting vehicle in order to chop the crop. Starting from the chopper, the chopped crop can be conveyed in the direction of a post-accelerator, which accelerates the harvested crop so that it can be thrown into a trolley, for example, via a discharge chute of the harvesting vehicle.
When the corn is harvested as crop, a conditioner is positioned between the chopper and the post-accelerator, which conditioner is preferably designed as a so-called cracker and strikes the harvested corn. When grass is harvested, the conditioner is replaced by a grass shaft, which then conveys the chopped grass from the chopper towards the post-accelerator. The grass shaft can also be called a connecting channel.
1 to 4 show different views or details of a grass shaft 10 according to the invention, the grass shaft 10 comprising a front wall 11, a rear wall 12 and side walls 13 extending between the front wall 11 and the rear wall 12. The front wall 11, the rear wall 12 and the side walls 13 together define a feed channel of the grass shaft, which has an inlet opening 14 at one end and an outlet opening 15 at an opposite end.
The grass shaft 10 can be mounted on the harvesting vehicle via fastening devices 16, specifically between the chopper of the harvesting vehicle and the post-accelerator thereof.
Arranged on at least one side wall 13 of the grass shaft 10 is a clamping lever 17 serving as a fastening device 16, which has an actuating handle 18 at a first end and a clamping section 19 at an opposite second end. Actuating handle 18 and clamping section 19 of the respective clamping lever 17 preferably run parallel to one another.
BE2019 / 5273
A clamping section 19 is preferably arranged on each side wall.
The respective clamping lever 17 is pivotally or tiltably mounted on the grass shaft 10, namely on a parallel to the one on a middle section 20 extending between the operating handle 18 and the clamping section 19, which extends transversely, preferably perpendicularly, to the operating handle 18 and the clamping section 19 respective side wall 13 extending bearing body 21 which has two bearing legs 21a, 21b. The middle section 20 of the clamping lever 17, which is pivotably or tiltably mounted on the bearing body 21, is guided between the two bearing legs 21a, 21b of the bearing body 21.
The respective clamping lever 17 can be pivoted or tilted exclusively by actuating the actuating handle 18 between the clamping position shown in FIGS. 1 and 2 and the release position stored in FIGS. 3 and 4, so that the respective clamping lever 17 is accordingly tool-free between the clamping position of FIG. 1 and 2 and the release position of FIGS. 3 and 4 can be transferred.
1 and 2, a recess 22 on the clamping section 19 of the respective clamping lever 17 engages with a mounting bolt 23 of a frame or the chopper of the harvesting vehicle so as to mount the grass shaft 10 and clamp it on the mounting bolt 23.
1 to 4, the respective mounting bolt 23, which engages in the respective recess 22 of the clamping section 19 of the respective clamping lever 17, is clamped between the clamping section 19 of the respective clamping lever 17 and counterholders 24 of the grass shaft 10. The counterholders 24 in particular prevent the grass shaft 10 from tilting in the clamped assembly position thereof. The grass shaft 10 has a locking device 25 for the respective clamping lever 17. The locking device 25 has a locking pin 26, which depends on whether the clamping lever 17 is in the clamping position
BE2019 / 5273
Fig. 1, 2 or the release position of Fig. 3, 4, engages in one of the locking openings 27 or 28.
Then, when the clamping lever 17 assumes the clamping position of FIGS. 1 and 2, the locking pin 26 engages in the locking opening 27 and thus locks the respective clamping lever 17 in its clamping position. On the other hand, when the clamping lever 17 is pivoted or tilted into the release position shown in FIGS. 3 and 4, the locking pin 26 engages in the locking opening 28 so as to lock the clamping lever 17 in its release position.
The two locking openings 27 and 28 are formed on a tab 29 which is fixedly connected to the bearing leg 21b of the bearing body 21 and is preferably angled at right angles thereto.
1 and 2, the clamping lever 17 can be locked via the locking device 25 both in the clamping position of FIGS. 1 and 2 and in the release position of FIGS. 3 and 4, FIGS. 5 and 6 show an embodiment of a Grass shaft 10, in which the locking device 25, which comprises a locking pin 26, locks the clamping lever 17 exclusively in the release position of FIG. 6, by the locking pin 26 engaging in a locking opening (not shown) in the central section 20 of the respective clamping lever 17. 5, however, the locking device 25 in the grass shaft 10 of FIGS. 5 and 6 is not effective; rather, a spring element 30 cooperating with the clamping lever 17 presses the clamping lever 17 automatically into the clamping position of FIG. 5, so that the clamping lever 17 5 must be shifted into the release position of FIG. 6 against the spring force of the spring 30.
In a further embodiment, not shown, based on the embodiment according to FIGS. 5 and 6, a spring element is dispensed with. Another is to secure the clamping position
BE2019 / 5273
Locking opening provided in the central section 20, in which the locking pin 26 engages. The locking pin 26 can be designed as a split pin in both exemplary embodiments.
According to a further exemplary embodiment (not shown), the clamping lever 17 is held in the clamping position by a toggle lever mechanism. For this purpose, the toggle lever is overstretched beyond its dead center, whereby a locking effect is achieved.
FIG. 7 shows a further exemplary embodiment of a grass shaft 10, in which 13 clamping sections 19 are provided on both side walls, each of which can engage in the mounting bolt 23. The clamping sections 19 are connected to one another in a rotationally fixed manner via a connecting element 35 - preferably a pipe. The connecting element 35 is rotatably mounted on brackets 36 which are attached to the grass shaft 10. By coupling the clamping sections 19 with the connecting element 35, advantageously only a single actuating handle 18 is required for simultaneously locking both sides of the grass shaft 10. For this purpose, an actuating lever 37 (see FIG. 8) is arranged on a clamping section 19, which is articulatedly connected via a connecting lever 38 to a lever 40 on which the actuating handle 18 is arranged. The lever 40 is rotatably mounted on a fulcrum 39 and by means of a pivoting movement in a direction of the double arrow 41, the clamping sections 19 can be moved from the clamping position (FIG. 7) to the release position (FIG. 8) and vice versa.
In a further exemplary embodiment of a grass shaft 10 according to FIGS. 9 and 10, the clamping sections 19 are likewise coupled to one another via a connecting element, but a lever 50 is provided for actuation, which lever is arranged in a rotationally fixed manner on one of the clamping sections 19 and with which the clamping sections 19 move the axis of rotation 51 can be moved from the clamping position (FIG. 9) into the release position (FIG. 10) and vice versa.
BE2019 / 5273
A locking device is preferably provided on the lever 50, which fixes the position of the lever 50 both in the clamping position and in the release position. For this purpose, a locking pin 52 is arranged on the lever 50, which can engage in locking openings 53, 54. In FIG. 9, in which the clamping position is shown, the locking pin 52 engages in the locking opening 53, which is covered by the lever 50. In this view, the free or unused locking opening 54 can be seen.
In FIG. 10, in which the release position is shown, the locking pin 52 engages in the locking opening 54, which is covered by the lever 50. The free or unused locking opening 53 can be seen in this view.
To disengage the locking pin 52 from a locking opening 53, 54, the lever 50 can be moved somewhat out of the plane of the image with the actuating handle 18, and to engage the locking pin 52 in a locking opening 53, 54 the lever 50 springs back accordingly.
The additional optional locking devices of the exemplary embodiments shown in FIGS. 1 to 6 can, of course, alternatively or additionally be provided on the exemplary embodiments of FIGS. 7 to 10.
A grass shaft 10 designed according to the invention can be easily mounted on the harvesting vehicle without tools and removed from the harvesting vehicle. The grass shaft 10 is held securely in its mounting position in the harvesting vehicle. There is no risk that the grass shaft 10 will shift unintentionally during operation and impair the flow of material.
