Compared with the prior art, the beneficial effects of the present invention include: the upper ends of a plurality of measuring cylinders are respectively fixed in the feeding ports of the turntable, and the bottom ends of the measuring cylinders are slidably arranged on the upper surface of the discharge plate; Circular movement on the discharge plate. The output end of the feeding equipment in the front section is set on the circumference of the feed port of the turntable. When one of the feeding ports stays at the output end of the feeding equipment, the material is filled into the cylinder through the feeding port. After a sufficient amount of time, after filling the drum, turn the turntable to replace the next empty measuring drum to accept the material. The measuring cup filled with material slides on the discharge plate under the drive of the turntable. When the discharge port and the lower end of the measuring cylinder are butted, the measuring cylinder is emptied. Then, under the rotation of the turntable, replace the measuring cylinder with the next filling material to the discharge port.

The threaded end of the screw 212 penetrates through the through hole 211 and is then screwed into the screw hole 121a. Thus, the plurality of measuring cylinders 200 are sequentially fixed on the tray 100 .

In order to clearly and simply highlight the functional characteristics of the discharging plate 300 , the rooting position of the discharging plate 300 is not described in detail in this embodiment. The discharge plate 300 abuts against the lower end surface of the measuring cylinder 200, so that the measuring cylinder 200 can slide on the discharge plate 300, so that the discharge plate 300 and the measuring cylinder 200 form a storage space to measure the material. At the same time, the discharge plate 300 is provided with a discharge port 310 on the movement track of the measuring cylinder 200 for emptying the material in the measuring cylinder 200 .
