Description

Self-propelled rice harvester

The utility model belongs to paddy field harvesting machinery in the agricultural machinery.

The stubble height that cuts of paddy rice harvesting is one of important indicator of evaluation harvester operation performance, and it directly affects the harvesting effect.The mode current, that the grain lifting frame seam structure of numerous cedings of Taiwan all adopts column lower end and lower fulcrum bar rear end to be positioned at the guard below and to link by securing member increases cutting height.In addition, existing from walking in the power chassis, because of no reverse gear in the speed changer and left and right steering structure, grain header can not be fallen back and left, right turns to, give paddy rice grain header harvesting operation to the row adjustment and manipulate and bring inconvenience.

The purpose of this utility model just provides a kind of novel self-propelled rice harvester, by changing the grain lifting frame seam and in the speed changer of walking the power chassis, increasing design reverse gear and left and right steering structure, reach reduction cutting height, the convenient purpose of using, improving operation quality and operating characteristics in the paddy field.

Basic design of the present utility model is, on the column with the grain lifting frame seam, following two ends respectively with fixed head, guard is affixed, the lower fulcrum bar rear end is also directly and below the guard or the affixed one in front, in the housing of speed changer, reversing shaft is installed, power input shaft, gear shaft, steering spindle, land axle, and the back gear that matches and install with each, shifting slide gear, gear wheel, there is the left side of tooth embedding the single side that two sides have the central gear of tooth embedding and a coaxial assembling, the right turn gear, a left side, right land axle gear, utilize fork to stir a shifting slide gear and a left side respectively, the right turn gear changes gear pair meshing relation, a setback and a left side of realizing this machine, the right turn motion.

The utlity model has that operation quality is good, paddy rice harvesting cut stubble low, advance, retreat, about turn to flexibly, handiness, harvesting operation be to the good characteristics of row performance.
