摘要： The present disclosure provides a ratooning rice harvesting header and a harvester including the same. The ratooning rice harvesting header includes a multi-layer adjustable disc cutter, a header, and an ear cutter. The multi-layer adjustable disc cutter is mounted below the header and located below a rear portion of the ear cutter. The ear cutter is mounted at a front end of the header. The multi-layer adjustable disc cutter includes at least one group of multi-layer disc cutting assemblies. Each group of multi-layer disc cutting assemblies includes two multi-layer disc cutting assemblies. Each of the multi-layer disc cutting assemblies includes three layers of vertically arranged blades. The use of the multi-layer adjustable disc cutter in cooperation with the ear cutter can reduce the straw-grain ratio of the part cut from the crops to reduce the power consumption of the harvester.

摘要： A forage harvester that includes a cutterhead assembly and two frame parts between which the cutterhead assembly is rotatably suspended. The forage harvester assembly is held on both frame parts by a clamp bearing that defines a rotary axis. Contact points between an element on the frame part side and an element on the assembly side of the clamp bearing lie on a spherical surface centered on the rotary axis.

摘要： An agricultural header for use with an agricultural harvester includes a header frame, a first row unit having a first row unit frame coupled to the header frame, and a second row unit having a second row unit frame coupled to the header frame. The header also includes a casting body coupled to the first row unit frame, a sensing unit of a stalk-diameter sensing system including a frame portion and a stalk feeler deflectably coupled to the sensing unit, and a point assembly pivotally coupled to the header frame. The point assembly at least partially covers the sensing unit. A crossbar member includes a first portion and a second portion with the first portion being pivotally coupled to the casting body to pivot about a first pivot axis. The crossbar member is pivotable about the first pivot axis between a first position and a second position.

摘要： An agricultural system includes a header with a feed roller configured to engage a crop and to drive material other than grain (MOG) of the crop toward a field. The agricultural system also includes a chopper configured to cut the MOG driven toward the field by the feed roller for discharge from the agricultural system and a control system configured to output a control signal to adjust a speed of the chopper relative to a speed of the feed roller based on a size of the MOG discharged from the agricultural system.

摘要： A crop stripper rotor includes a plurality of stripper teeth sections and backer plates secured to a central core by threaded fasteners. The stripper teeth sections have stripper teeth that project radially outwardly from a mounting base, and the backer plates have teeth that fit behind the stripper teeth. The stripper teeth sections and backer plates are sandwiched between opposing flanges of adjacent bent sheet metal sections of the central core. An alignment and mounting system includes a pair of alignment slots in each stripper teeth section and backer plate that open radially inwardly. A first pair of threaded fasteners mate with the alignment slots to set the depth and alignment of the stripper teeth sections and backer plates relative to the central core. A second pair of threaded fasteners are inserted through the aligned mounting bores of the stripper teeth sections and the backer plates to complete the assembly.

摘要： A clean out system of a header for an agricultural vehicle. The header includes a frame with a floor having at least one cutout for allowing an unwanted material to pass therethrough. The clean out system includes at least one door configured for pivotally connecting to the floor and selectively engaging with the at least one cutout, a latching mechanism connected to the at least one door and configured for securing the at least one door to the frame, and at least one actuating member operably connected to the at least one door and configured for selectively latching the latching mechanism and pivoting the at least one door in between an open position and a closed position.

摘要： One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

摘要： A feeder housing for an agricultural harvester includes: a housing; a conveyor system disposed in the housing, the conveyor system including a drive shaft, at least one drive loop coupled to the drive shaft such that rotation of the drive shaft causes rotation of the at least one drive loop, and a plurality of crop grabbers coupled to the at least one drive loop; a rock beater disposed in the housing and including a rotatable beater roll and at least one fin carried by the beater roll; and a motor coupled to the beater roll and configured to rotate the beater roll. The motor is an electrically powered motor or a hydraulically powered motor. The motor is coupled to the beater roll such that the motor is configured to rotate the beater roll without rotating the drive shaft.

摘要： An agricultural harvester includes an annular housing having an arcuate cross-section such that the annular housing defines a toroidal chamber therein.
Furthermore, the agricultural harvester includes a blade supported below the annular housing in a vertical direction, with the blade configured to sever top portions of plants from stalks of the plants. Additionally, the agricultural harvester includes a crop flow director positioned above the blade in the vertical direction, with the crop flow director configured to direct the severed top portions into the toroidal chamber. Moreover, the agricultural harvester includes an elevator assembly supported relative to the annular housing. In addition, the agricultural harvester includes a fan assembly configured to generate a flow of air through the annular housing to convey the severed top portions from the toroidal chamber to the elevator assembly.-

摘要： A header of a combine harvester includes a belt conveyor configured to direct a movement of harvested crop material toward a feederhouse of the combine harvester. The belt conveyor is located adjacent an inlet of the feederhouse. The belt conveyor includes at least one protrusion extending radially from the belt conveyor that helps direct movement of harvested crop material toward the feederhouse.
