    The invention relates to a weighing device for a plot combine with a weighing container supported by a load cell arrangement relative to a frame,
    In order to avoid the disadvantages of weighing devices for detecting the harvest weight with weighing containers, which are freely suspended on the parcel combines for adaptation to slopes, it has already been proposed (US Pat. No. 5,487,702 A, US Pat. No. 6,313,414 B1) to load the weighing container by means of a load cell arrangement to support a frame that is rigidly connected to the plot harvester. In order to be able to take into account vibration and inclination influences on the weighing result, a reference weight with an additional load cell is used so that the difference between the known size of the reference weight and the measured variable detected with the aid of the load cell serves as a correction measure for the weight of the weighing container in the weighing cell arrangement located crop can be used. A disadvantage of these known weighing devices is initially the additional expense caused by the additional reference weight and the cell provided for this purpose. In addition, it is to be feared that the measurement errors of the individual load cells add up to the load cell arrangement. A further disadvantage is the fact that due to the support of the weighing container over several load cells of the weighing line arrangement, the risk exists that the load cells are braced against each other, which leads to measurement errors. Are used to avoid such mutual tension of the load cells elastically resilient elements, so increases the tendency to vibration of the weighing container, which should be avoided. 2/9 2
    The invention is therefore based on the object, a weighing device for a parcel combine in such a way that with the smallest possible space requirements advantageous conditions for accurate detection of the crop weight can be created, largely independent of design tolerances.
    Starting from a weighing device of the type described above, the invention solves this problem by the fact that the weighing container is guided displaceably on the frame in the manner of a Gelenkparallelogramms in the vertical direction and that the load cell arrangement comprises a vertically articulated between the frame and the weighing container load cell.
    By guiding the weighing container in the manner of a jointed parallelogram, a solely vertical displacement of the weighing container relative to the frame is ensured in a simple manner, so that a single load cell suffices for weight detection. The restriction to a single load cell avoids all the difficulties that would have to be considered with weighing arrangements of multiple load cells. The weighing device according to the invention thus represents a comparatively simple, robust construction, which is well suited for rough operation on a parcel combine and, due to the single degree of freedom for the weighing container structurally predetermined in the vertical direction, enables a high measuring accuracy. In order to be able to take account of inclinations and vibrations, acceleration sensors and inclination sensors can additionally be used in a manner known per se.
    Articulated parallelograms with rotatably mounted handlebars may require maintenance in order to ensure consistent friction conditions in the joints over longer periods of time. For this reason, it is recommended to store the weighing container on both sides clamped leaf springs in the manner of a Gelenkparallelogramms on the frame, because in this case can be dispensed with joints. The leaf springs also provide a backlash-free side guide for the weighing container. The required spring load for the load cell is essentially negligible so that the effects of the changing spring forces due to the displacement of the weighing container have no influence on the measurement result.
    Depending on the articulation, the load cell, which is articulated vertically between the frame and the weighing container, can be subjected to pressure or tension via the weighing container. Particularly simple construction conditions, however, arise when the load cell is loaded to train, because the load cell can be easily connected to the frame and the container under a tensile load without torque. For this purpose, yes, the load cell only needs to be hinged on all sides pivotally between the frame and the container. An articulation via a universal joint or a ball joint fulfills these requirements in a simple manner.
    To create advantageous design conditions, a weighing container receiving subframe can be stored in the manner of a Gelenkparallelogramms on the frame, wherein the load cell acts on the subframe. By this measure, the weighing container can be built comparatively easily regardless of the storage and guiding conditions, because the bearing and executives are absorbed by the subframe.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a weighing device according to the invention for a plot combine in a simplified, partly torn-off side view, and FIG. 2 shows this weighing device in a rear view from the frame side.
    The illustrated weighing device comprises a frame 1 which can be mounted rigidly on a plot harvester in the form of a vertical frame and a weighing bin 2 which is displaceably guided on the frame 1 in the vertical direction in the manner of a jointed parallelogram 3. This Gelenkparallelogramm 3 is formed by leaf springs 4, which are clamped on both sides and the frame 1 with a 4/9
    Connect subframe 5, which receives the weighing container 2. The subframe 5 is in the form of a T-shaped carrier, wherein two leaf springs 4 at the ends of the transverse leg 6 by means of clamping blocks 7 and a central leaf spring 4 on the front side of the web 8 of the T-shaped subframe 5 also by means of a clamping pad. 7 are clamped. The clamping of these leaf springs 4 in the region of the frame 1 is carried out in a similar manner via connected to the frame 1 support body 9, to which the leaf springs 4 are held pressed by clamping pads 10. At the upper leg 11 of the frame-shaped frame 1, a load cell 12 is suspended via a universal joint 13. On the opposite side, the load cell 11 engages via a ball joint 14 on a support lug 15 of the subframe 5, as can be seen in particular in FIG. The subframe 5, which is guided over the clamped on both sides leaf springs 4 in the manner of a Gelenkparallelogramms 3 relative to the frame 1 in the vertical direction, is thus suspended on the frame 1 via the load cell 12 that only vertical forces can be absorbed by the load cell 12 and Transverse forces have no influence on the measurement result.
    The crop to be weighed is filled in batches in the weighing container 2 and weighed by means of the load cell 12. Via a folding bottom 16, which can be actuated by a pivoting cylinder 17, the weighed crop can be discharged in a collecting container. 5.9
