1985年全国统型设计的JZ350砼搅拌机上料斗(图1),至今全国已生产近万台,通过对用户的回访和返修情况发现,该型式上料机构结构简单,动作灵敏。但也有不足之处,如由于三组滚动轮均设置在导向槽钢内,首先要将A、B、C三根轮轴的轴线在一个空间平面内,同时必须要保证三根轴的平行度;再则,由于斗门的回转铰点E在斗体D的内侧,当斗门轮轴B进入岔道时,斗门必然围绕铰点E作回转运动,斗门底板G点将向斗体F点靠拢,而斗
In 1985, the nationally designed JZ350 hopper hopper on the mixer (Fig. 1) has produced nearly 10,000 sets of rigs nationwide. It has been found through the return visits and repairs to users that the type feeding mechanism has a simple structure and is sensitive to motion. However, there are also deficiencies. For example, since the three sets of scroll wheels are all arranged in the guide channel steel, the axes of the three axles A, B, and C must first be in a spatial plane, and the parallelism of the three axes must be ensured; Because the pivot hinge point E of the bucket door is inside the bucket body D, when the bucket wheel axle B enters the ramp, the bucket door must rotate around the hinge point E, and the bottom plate G of the bucket door will move closer to the bucket body F point, and the bucket
