Definitions
- the invention relates to a mower conditioner according to the preamble of claim 1.
- Mower conditioners are suitable and applicable for mowing and subsequent processing of the stalks for faster drying.
- a known mower conditioner of this type (EP 0 116 662 AI)
- the mower is articulated in a height-adjustable manner on a main frame independently of a downstream conditioner.
- the conditioner can optionally be pivoted relative to the main frame into an inoperative position, but is permanently assigned to it in operation, in which the support arms of the conditioner rest on the top of the main frame. This relieves the mower of the conditioner's weight.
- this device arrangement has the following disadvantages:
- the distance between the mower and the conditioner must be large enough so that the mower does not hit the conditioner when evading.
- mower conditioners known (FR 2 560 484 AI), in which the mower and conditioner are designed as a structural unit which can be moved as a whole on a main frame, e.g. B. articulated via parallel link and a weight relief spring are. Due to the high total weight, this unit reacts only relatively sluggishly on uneven floors. In addition, a complex weight relief spring arrangement must be provided, which ensures that the spring relief on the structural unit remains almost constant over the stroke.
- the position of the conditioner relative to the main frame and the mower can now be changed during operation and especially when the ground is uneven.
- both units now adapt to uneven ground.
- the conditioner can thus be arranged at a short distance from the mower, as is best for an optimal material transfer.
- the mower can adapt to the bumps more easily and quickly, despite the small weight relief spring. It is also advantageous that the conditioner puts less strain on the mower due to the articulated connection. Components can be designed more easily.
- the connecting link is designed as a swivel joint, which ensures that the
- Conditioner can be raised with the mower and at the same time can be swiveled, which is particularly important for mowers supported on parallel bars.
- the conditioner is articulated to the main frame by means of at least one support element, which is articulated on one side pivotably about at least one upper horizontal hinge axis on the main frame and on the other side pivotably on the conditioner.
- the lower hinge axis of the support element and the axis of rotation of the preparation rotor lie approximately in a horizontal plane.
- the conditioner be pivoted on the main frame both about an upper horizontal longitudinal central axis and pivotable about a horizontal transverse axis.
- FIG. 1 is a schematic side view of a mower conditioner in the normal working position
- Fig. 2 is a view of FIG. 1, but in the raised alternative position of the mower conditioner when driving over a raised ground.
- Fig. 3 shows an enlarged front view of a second embodiment of a support element for the pendulum and pivotable connection of the conditioner to the main frame.
- the mower conditioner consists of a mower 1 and a conditioner 2 for straw material and, as shown in FIG. 1, can be designed as a trailer device. In working position 3, it is moved from an agricultural towing vehicle via a drawbar 4 offset to it in the direction of travel indicated by arrow 5 and is driven by the towing vehicle via an articulated shaft (not shown).
- the mower 1 is designed as a disc mower of conventional design with mower rotors 6.
- the mower 1 is articulated up and down on a main frame 10 via parallel links 7, 8 and weight relief springs 9.
- a main frame 10, the drawbar 4 is articulated and articulated in its pivoting position via a pressure medium drive, not shown.
- the wheels 11 are rotatably attached to the rear ends of trailing arms 12.
- the front ends of the trailing arms 12 are pivoted on the main frame 10.
- the height of the main frame 10 can be adjusted to the ground by means of hydraulic cylinders 13.
- the hydraulic cylinders 13 act on the one hand on the main frame 10 and on the other hand on the trailing arms 12.
- the conditioner 2 has a tine rotor 14 which rotates in the direction of the arrow 16 around a horizontal axis of rotation 15 lying transversely to the direction of travel 5.
- the tine rotor 14 is supported on both sides in side walls 17 connected by cross struts, not shown, and covered above by a cover 18.
- a cover 18 For more details on the design a conditioner 2 is not discussed here, since these are known in principle.
- the connection is designed so that the conditioner 2 inevitably follows the movements of the mower 1 without significantly changing its position in relation to the mower.
- the conditioner 2 is coupled to the mower 1 on both sides of the mower by a swivel joint 19 with a horizontal transverse axis 20 located immediately behind and laterally outside the orbit of the outer mills 6 with the mower 1.
- the connection is made by upward-directed, tension-loaded links 21 which are articulated about an upper horizontal hinge axis 22 on the main frame 10 and about a lower horizontal hinge axis 23 on the conditioner 2 or on its rare walls 17. Both hinge axes 22, 23 are arranged parallel to the transverse axis 20.
- Angle brackets 24 are fastened on both sides of the mower mechanism 1, the upward-pointing legs 25 of which are designed as double brackets, each with a hole. Each double strap receives between them a side wall 17 with an equally large bore.
- the articulated connection is made by a safety bolt, not shown, penetrating all three holes.
- the hinge axes 22, 23 are arranged axially parallel to the transverse axis 20. So that the conditioner 2 changes its position in relation to the mower 1 as little as possible in the event of uneven ground, the lower hinge axis 23 is approximately at the same height from the ground as the axis of rotation 15 19 offset relative to the axis of rotation 15 with an edge, so that the pivot joint 19 is at a greater distance from the pivot axis 23 than the axis of rotation 15.
- both the parallel links 7 , 8, the swivel 19 and the links 21 may be provided with ball joints, not shown.
- both links 21 only a single one in the middle can not Handlebar shown be provided, which engages at the top by a ball joint on the main frame 10 and below by a ball joint on the conditioner.
- the mower 1 slides over the ground on sliding elements 25 and can adapt to all uneven ground.
- the conditioner 2 also inevitably undergoes pivoting relative to the mower 1, so that a good material flow from the mower 1 to the conditioner 2 is ensured in the shortest possible way in any operating state.
- FIG. 2 in which the mower 1 is shown in the evasive position 26 raised by a floor elevation, the conditioner 2 pivots clockwise when the mower 1 is raised and at the same time the handlebars 21 rearward via the articulated axes 22, 23.
- the conditioner 2 thus follows the movements of the mower 1 in accordance with its parallel link arrangement 7, 8 and remains at an almost constant distance from the ground.
- the type of construction according to the invention can not only be dimensioned lighter, but above all adapts faster and more easily to all uneven ground.
- FIG 3 only a U-shaped support element is shown schematically, consisting of a support beam 27 which engages centrally through a single ball joint 28 on the main frame 10 and is also connected to the links 21 on both sides by ball joints 29.
- the connection of the conditioner 2 to the handlebars 21 is also unchanged by means of ball joints 30.
- This design enables in a structurally simple manner both an oscillating adjustment of the conditioner about a horizontal longitudinal central axis 31 and at the same time about the horizontal transverse axis 22 as well as an adjustment in the case of unilateral unevenness.
- the mower can also be used as a drum mower or as a combination of mower rotors and drums be formed.
- squeeze roller conditioners or other treatment elements can alternatively be used.
