全国统型JZC350砼搅拌机,其操纵机构由于采用了平面四连杆机构而使操纵力大为降低,因而受到操纵者的欢迎。但由于操纵杆运动方向与滑塞运动方向相同,因而操纵时,只能站在滑塞的运动方向上,而出料时又得站在另一位置(转90°),所以很不方便。为此,我们将平面四连杆改为空间四连杆机构(见附图),这样操纵者所站方向改变90度,以在一个位置上操纵按扭与操纵,且由于四连杆的杆长未变,所以操纵力
The national unified type JZC350 mixer, whose operating mechanism has greatly reduced the operating force due to the use of a planar four-bar linkage, and is therefore welcomed by operators. However, since the direction of movement of the joystick is the same as that of the slide, it can only stand in the direction of movement of the slide when it is manipulated, and has to stand at another position (turn 90°) when discharging, so it is inconvenient. For this purpose, we changed the plane four-bar linkage to a space four-bar linkage (see drawing) so that the operator’s direction was changed by 90 degrees to manipulate the buttons and maneuvers in one position, and due to the four-bar linkage The length has not changed, so the operating force
