求翻译：针对目前大豆收割装置在收割作业时，割刀在相对机架作往复直线运动的同时伴随机组前行， 其相对地面的运动是横向往复和纵向前行的合成， 这种运动规律严重影响着切割质量。是什么意思？

For soybean harvesting device operating in the harvest, the cutting knife in the relative rack reciprocating linear motion, accompanied by the unit before, the relative movement of the ground is horizontal reciprocating longitudinal forward synthesis, this law of motion, a serious impact on cutting

Harvests the installment in view of the present soybean when harvests the work, the cutter while the relative rack makes the straight reciprocating main motion to follow the unit vanguard, its relative ground movement is the crosswise reciprocation and the longitudinal vanguard synthesis, this kind

Current soybean harvesting device at the time of harvesting, cutting knife in relative reciprocating linear motion accompanied by a rack unit to move on, its relative ground movement is horizontal and vertical back and forth along the synthesis, which seriously affect the motion of cutting quality.
