摘要:
A self-propelled harvesting machine having an internal combustion engine, a propulsion system that can be operated to cause the harvesting machine to move across a field with a propulsion speed, a crop material pick-up device for picking up the crop material from a field, a crop material processing device for processing the crop material that has been picked up, a control unit for specifying the speed of the internal combustion engine, and a through-put measurement device for determining the through-put of the harvesting machine. The control unit can be operated to vary the speed of the internal combustion engine depending on the signal from the through-put measurement device. In this manner the RPM of the internal combustion engine that is most favorable in terms of fuel consumption and that corresponds to the power to be applied at a given through-put can be specified.

The agricultural harvesting machine having a crop picking head includes a pickup conveyer which can be driven so as to pick up the harvested crop at a first adjustable speed, a discharge conveyer which can be driven so as to receive the harvested crop picked up by the pickup conveyer, transport the harvested crop, and discharge the harvested crop at a second adjustable speed, and a feed-in conveyer disposed in a feed-in channel of the harvesting machine that can be driven so as to receive the harvested crop from the discharge conveyer, transport the harvested crop, and discharge the harvested crop to a harvested crop processing unit at a third adjustable speed. The third speed and the first speed are independent of one another, and the second speed is defined by the first and third speeds and falls in a range between the first and third speeds.

Recent production methods for 3D video as a general rule generate stereo images in a same phase of movement. The left and right images of a stereo pair thus image the recorded (or rendered) scene at a same point of time. Correct reproduction consequently requires the two images to be shown concurrently. This is, however, not true for all apparatuses such as, for example, 3D television sets including the so-called shutter technology, which show the left and right images in temporal succession. This temporally offset reproduction of the two stereo images results in clearly perceivable image errors. The invention describes a method for compensating such image errors. This is achieved by interpolating the images of one of the channels.

A bearing assembly of a crop conveying and/or crop processing element for a harvesting machine includes a rolling contact bearing, a stationary disk spaced axially away from the rolling contact bearing and an impeller disk rotating with the crop conveying and/or crop processing element. The stationary disk is positioned between the rolling contact bearing and the impeller disk such that interaction of the stationary disk with the impeller disk prevents intrusion of undesirable material.

A foreign body detector for an agricultural harvester is provided having a sensing element which is fitted such that it is movable transversely to a direction of conveyance of the crop and which, during the harvesting operation, bears against the received crop. The foreign body detector has a position sensor set up to register the position of the sensing element, and an evaluation circuit, which can be operated to calculate, on the basis of the signals of the position sensor, information relating to the velocity and/or acceleration of the sensing element and, for the purpose of generating a signal value indicating the take-up of a foreign body, to make a comparison with a threshold value.

The invention relates to a field chopper having at least one rotatable lower rough-press roll and at least one rotatable upper rough-press roll. Between the rough-press rolls crop is pressed and fed to a chopping drum where blades chop the crop. A space is defined down stream of the moveable rough-pressing roll between the chopping drum, the stream of pressed crop and the movable rough-press roll. Located in this space is a pressing element that acts on the pressed crop and which exerts a rough-pressing effect on the pressed crop downstream of the movable rough-press roll and upstream of the chopping drum.

An apparatus for filling and closing sacks or bags, in particular paper side folding sacks, has a plurality of processing stations including a filling station, stationary clamping elements for holding the sack in an open position and a slide cyclically movable between processing stations. Outside grippers are mounted on the slide which are designed to grasp an at least partially filled sack at its side folding by clamping the folding from the outside in said filling station and transporting the sack by means of the slide to the succeeding processing station.

The invention relates to a feeding device (32) for a field chopper (10), comprising: at least one rotatable lower feedroll (34, 35), at least one rotatable upper feedroll (36, 37), between which a windrow can be fed and led to a chopping device (22), and an external force-activated adjustment drive (68), with which the position of at least one of the feedrolls (36, 37) can be changed relative to the other feedroll (34, 35). It is proposed that a spring (58) be arranged between the adjustment drive (68) and the feedroll (36, 37) that can be moved by this drive. The spring (58) enables the movable feedroll (36, 37) to react more quickly or immediately to sudden changes in windrow height independent of the inertia of the adjustment drive (68).

Method for the analytical determination of the concentration of a component of a medical sample, in which a reaction of the sample with reagents leads to a time-dependent change S(t) in a measured quantity S and the concentration C correlates according to an evaluation curve C(X) with an input variable X derived from S(t), in which the calibration curve is ambiguous for at least a portion of the possible X values. In order to assign an input variable X to one of the sub-sections and thereby to obtain an unambiguous correlation to a particular concentration C, a training run and an analysis run are performed. In the training run, a discrimination algorithm is performed at least once, in which a discriminator set is generated from measurements of S(t), a score is generated in each case from the latter with a multivariate statistical technique and it is checked whether the scores can be divided into separate subsets, in which the concentrations are correctly assigned to the sub-sections of the calibration curve. The discrimination algorithm is repeated with different discriminator sets generated according to different generation methods from the measurements of S(t), in order to establish an operative discrimination algorithm. In the analysis run, an analysis score is calculated from measurements of S(t) according to the operative discrimination algorithm, the analysis score is compared with the boundary score and the measurement result is assigned to one of the sub-curves of the calibration curve by comparison of the analysis score with the boundary score.
摘要:
A bearing arrangement for a harvesting machine, including a bearing configured to couple a rotatable shaft with a chassis of the harvesting machine, a first element coupled with the shaft so as to be rotatable therewith, and a second element coupled with the chassis of the harvesting machine. Additionally, at least a portion of the second element is substantially concentrically enclosed by the first element and the first and second elements cooperate to define a contactless seal configured to substantially prevent contamination of the bearing. The shaft is coupled with a product treating element, such as a crop feeding and/or processing element that is driven or idle rotating.
