Abstract:
One or more techniques and/or systems are disclosed for automatically adjusting conditioning rollers of a windrower implement, such as those used to condition hay and other windrowed crops. Adjustments can be made on the fly to rollers used to condition the crop based on several factors such as the condition of the crop, the density, speed, header conditions, and more. Sensors can be used to detect the crop's and others' conditions, and automatic adjustments can be made, such as the distance between conditioning rollers, and/or the pressure applied by the rollers, to meet a desired crop condition for the windrows.
Abstract:
An agricultural machine system includes: a mower-conditioner machine including a mower-conditioner machine frame, a plurality of conditioner rolls coupled with the mower-conditioner machine frame, and a pivotable swath gate coupled with the mower-conditioner machine frame; a control system operatively coupled with the mower-conditioner machine frame, the control system including: a controller system configured for: determining a swath gate position adjustment based at least in part on a conditioner speed of the plurality of conditioner rolls.
Abstract:
A pull-type mower conditioner includes a crop cutting assembly that severs crop material from the ground and a lift mechanism configured to raise and lower the crop cutting assembly to a desired height having at least one lift cylinder and a hydraulic lift circuit supplying hydraulic fluid to the at least one lift cylinder. The mower conditioner also includes a conditioning mechanism receiving the severed crop material from the crop cutting assembly. The conditioning mechanism includes a pair of counter-rotating conditioning rolls to condition the crop material and a tensioning assembly that urges the conditioning rolls relatively toward one another and resists their separation. The tensioning assembly includes a pair of hydraulic tension cylinders and a hydraulic conditioner circuit configured to supply hydraulic fluid to the tension cylinders. The hydraulic tension circuit has a supply line leading to a supply valve, wherein the supply line connects to the lift circuit.
Abstract:
As crop materials are severed from the field, they pass through two successive pairs of counter-rotating conditioning rolls before being returned to the ground. The front rolls are preferably ribbed, metal rolls wherein the ribs of one roll are intermeshed with those of the other roll so as to crimp the stems of the crop materials as they pass between the rolls. The hard metal ribs also aggressively feed the materials rearwardly into the second set of rolls, which are preferably compressive surface rolls made of rubber or the like and provided with wide, intermeshed bars about their periphery. The tension mechanism for the rolls includes single-acting hydraulic cylinders that squeeze the rolls together to the extent permitted by adjustable stop structure used to set gaps between the rolls. In typical operations, the gap between the rear rolls is set to be considerably smaller than the gap between the front rolls. Great flexibility in the degree of conditioning experienced by the crop materials is achieved by the nature of the rolls and the ease with which roll pressure and spacing can be adjusted.
Abstract:
A header designed for tall crops includes a sickle knife for cutting at the ground, an auger behind the knife, a conditioning system at a discharge for forming a swath and a reel with pivotal bat fingers controlled by a linkage which co-operates with a cam of the reel. An upper auger extends across the header parallel to the cutter knife above and in advance of the reel with its flight driving the crop inwardly. Vertically standing sickle knifes extend between the ends of the frame and the upper auger and each includes forwardly extending top and bottom dividers. The conditioning system includes two fluted rollers and a third parallel roller located behind the nip between the fluted rollers so as to engage the material as it emerges from the nip to force the material round the upper roller to further bend the crop material.
Abstract:
A device for processing fodder including a rotor driven in rotation about its longitudinal axis, a first guide element partially surrounding the rotor, a second guide element configured to occupy at least two positions relative to the rotor, a first control member configured to move the first guide element into at least two positions relative to the rotor and to hold the first guide element in these positions, a link between the first guide element and the second guide element so that a change of position of the first guide element modifies the position of the second guide element, and a second control member configured to dispose the second guide element according to the various configurations.
Abstract:
A crop conditioner is equipped with an impeller including a rotor to which a plurality of conditioner tines are respectively pivotally mounted at one of their ends. The tines are contoured so that they release crop at an appropriate location for the crop to engage the forming shields and thus become part of a well-defined windrow.
Abstract:
A pair of superposed parallel crop conditioner rolls, one journaled in a frame on a fixed axis, the other mounted for generally upward and downward movements toward and away from the one roll. Springs yieldingly urge the moveable roll towards the fixedly positioned roll, and stop elements limit movement of the moveable roll toward the fixedly positioned roll. Adjustment mechanism positions the moveable roll generally forwardly or rearwardly relative to a position vertically spaced from the axis of the fixedly positioned roll.
Abstract:
A conditioning machine for agricultural straw or blade material embodying a conveying drum equipped with conveying tools or implements. The conveying drum in conjunction with a guide wall forms a conveying channel which is provided with means for exerting a conditioning action upon the conveyed straw or blade material. According to important aspects of the invention the spacing between the ends of the conditioning means situated closest to the jacket or outer surface of the conveying drum and the circular path of travel of the ends of the conveying tools is smaller than the smallest inner height of the conveying channel between the jacket of the conveying drum and the guide wall measured from the axis of rotation of the conveying drum.
