A self-adaptive throwing device for stalks cutting and discharging in the longitudinal axial flow combine harvesters comprises a longitudinal axial flow stalk discharging and guiding device, a stalks remnant shredding device, a wind direction and wind speed detection device, a reaping region identification device, an operating speed sensor, a shredding revolution speed sensor, a width adjustable throwing device, a self-adaptive throwing real-time control system. The throwing width is self-adaptive based on the machine operating speed, wind speed, wind direction, the position of the region having been cut and the region waiting to be cut, so as to achieve the full width throwing of the stalks remnant. An arc stalk guiding plate and a flow separating bar are mounted in the longitudinal axial flow stalk guiding device to make the shredding load more even.

An agricultural harvester includes a chassis; a threshing and separating assembly carried by the chassis; and a chopper assembly carried by the chassis that receives crop material from the threshing and separating assembly. The chopper assembly includes at least one movable chopping knife; a plurality of counter knives movable between a first knife position and a second knife position, the plurality of counter knives configured to cooperate with the at least one chopping knife to cut crop material when in the first knife position; a shear bar movable between a first bar position and a second bar position; and a linkage assembly connected to the plurality of counter knives and the shear bar such that the linkage assembly is selectively actuable to simultaneously move the plurality of counter knives and the shear bar between their respective first and second positions.

A cutting device for agricultural crop has cutting elements and a rotor element rotating in operation about a rotor axis. The cutting elements are arranged in a cutting position stationarily relative to the rotor element and are able to yield in a springy fashion. The rotor element has a central body that is provided with a central conveying section and with at least one axial conveying section. The central conveying section has central conveying elements correlated with the cutting elements. The at least one axial conveying section is provided with an axial conveying element extending spirally at least in sections about the rotor axis. The at least one axial conveying section of the central body has a first radius and the central conveying section of the central body has a second radius, wherein the first radius is larger than the second radius.

A mobile machine is described. In one example, the machine includes a first subsystem comprising propulsion components configured to propel the mobile machine, a second subsystem, a first drive mechanism, a second drive mechanism, a coupling mechanism, and a controller configured to actuate the coupling mechanism to selectively couple one of the first or second drive mechanisms to drive one or more components of the second subsystem with variable speed and direction.

A method for the operation of a combine harvester includes processing a harvested material flow by at least one axial separator and ejecting a residual material flow formed in this way from the combine harvester by at least two ejection devices. The axial separator is formed by a movable vane element by means of which the residual material flow exiting from the axial separator is distributed on a work member downstream of the axial separator. In order to further improve the distribution of the residual material flow on the field, an actual distribution of the residual material flow on the two ejection devices is detected, wherein, when a deviation of the actual distribution from a predetermined reference distribution is detected, the vane element is readjusted so that the actual distribution is at least approximated to the reference distribution.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The destructor is mounted on a suitable drive shaft within the straw path and the chaff and weed seed material is carried from the rear end of the sieve to the destructor on the straw chopper by one or more fans driving the material through a transfer duct.
