With the supporting harvest corn device of grain combine
The utility model belongs to the crops harvest machinery, particularly with the supporting harvest corn device of grain combine.
For improving the availability of self-propelled grain cbmbine harvester, the domestic producer that has is the outfitting tool of self-propelled corn mowing machine configuration harvesting corn, form by ear harvesting bench, straw cutter and conveying plant, plucking steady platform is articulated on the grain combine, sidepiece at ear harvesting bench is equipped with conveyer, at the rear portion of grain header straw cutter is being set.During work, ear harvesting bench is finished and is plucked fringe, is carried by the conveyer side direction then, and the side goes out fringe and puts the shop, and the straw cutter that is positioned at the grain header rear portion is with stalk crushing and returning.Its weak point is that this apparatus structure is compact inadequately, and power transmission is disperseed, and appearance and size is big, and straw cutter can not be adjusted the height that straw cuts stubble with the fluctuating of landing ground.
The purpose of this utility model is to provide a kind of and the supporting harvest corn device of grain combine, compact conformation not only, and power transmission is concentrated, and appearance and size is little, and straw cutter can be adjusted the height that straw cut stubble with the fluctuating of landing ground.
The utility model is achieved in that a kind of and the supporting harvest corn device of grain combine, comprise ear harvesting bench, conveying plant and straw cutter, exit at ear harvesting bench laterally is installed with the conveying screw feeder, both sides on screw conveyor shaft are being provided with helical blade respectively, and the hand of spiral of two helical blades is opposite, article two, helical blade disconnects at the middle part of screw conveyor shaft, in the centre position of carrying screw feeder casing bottom ear outlet is being set, bottom-hinged at ear harvesting bench straw cutter, on the cutter shaft of straw cutter, upper cutter is installed, top in the straw cutter casing is fixedly mounting ledger-plate, the rear lower of straw cutter casing affixed the support wheel that mops floor, on the hitching axis of carrying frame end, screw feeder rear portion, drive is installed, drive is given the power transmission shaft of carrying the screw feeder rear portion by driving-belt with the power transmission of combine, and power transmission shaft passes to the conveying screw feeder respectively through drive again, snapping bar in straw cutter and the ear harvesting bench.
During the utility model work, finish the fringe work of plucking with ear harvesting bench, pluck the conveying screw feeder lateral transfer that the corn ear that takes off is laterally installed by the ear harvesting bench exit, about concentrate, land from the ear outlet of carrying screw feeder casing lower middle position and to put the shop, so just make the utility model compact conformation, appearance and size is little, owing to, make the utility model power transmission concentrate at ear harvesting bench bottom-hinged straw cutter.The rear lower of hinged straw cutter casing is installed with the support wheel that mops floor, and when work, can float with the fluctuations profiling on ground, can remain the certain altitude that straw cuts stubble.
