Effect of sliding cutting angle of bush reciprocating cutter on bush cutting

摘要: 为了解往复式灌木切割器的滑切角对切割力的影响，在自制的往复式单刀切割试验台上，通过改变滑切角角度研究了滑切角与灌木最大切割力的关系，以及刀刃角和曲柄转速对滑切过程的影响。结果表明：1）往复式灌木切割器的滑切角适用范围为0°～10°。2）当滑切角较小时（≤10°），增大刀刃角有利于滑切过程并降低最大切割力。3）当滑切角较小时（≤10°），增大曲柄转速能抑制灌木茎秆的外滑，进而降低最大切割力；若滑切角过大（≥15°），则抑制效果不明显，不能降低最大切割力。Abstract: In order to understand the effects of sliding cutting angle of the bush reciprocating cutter on cutting force, we studied the relationship between sliding cutting angle and maximum bush cutting force through altering its sliding cutting angle on the home-made reciprocating single blade cutting test equipment. Then more tests were done in similar ways to research the effects of blade angle and crank speed on the sliding cutting process. It is found that 1) the applicable sliding cutting angle for bush reciprocating cutter was at 0°-10°, 2）increasing the blade angle was favorable for the sliding cutting process and reduced the cutting force when the sliding cutting angle was small(≤10°), and 3）increasing the crank speed restricted the bush stalk sliding toward outside and reduced the maximum cutting force when the sliding cutting angle was small(≤10°). Conversely, if the sliding cutting angle was too large(≥15°), the restriction by increasing crank speed was too insignificant to reduce the maximum cutting force.
