The utility model relates to a kind of
coffee bean quantitative weighing
machine, including extraction mechanism and weighing mechanism, weighing mechanism includes shell,
round bar, connecting block, accommodating groove, moving rod and weight, the two sides arm front end of shell is provided with
waist shape hole, connecting block is rotatably installed on
round bar, the front side of connecting block extends with the extension plate of forward, moving rod is worn and is set extension plate, weight is detachably installed in the left end of moving rod, the rear side of connecting block extends with the rear extension bar, accommodating groove is fixedly installed in the rear side of extension bar;By using the above technical scheme, the coffee beans extracted by extraction mechanism are sent into accommodating groove, the principle of lever is used, the quantitative weighing of coffee beans is realized by weight, when the weight of coffee beans end is greater than the weight of weight end, connecting block will move
clockwise around
round bar, to make coffee beans in accommodating groove slide from accommodating groove, then
discharge from the bottom end of shell, to complete the quantitative extraction of coffee beans without manual operation.
