As shown in Figure 10, the drug crushing method implemented by the drug crushing device of this embodiment includes the following steps:

Swinging and mashing medicine stage: the rotating drive body 4 drives the moving gear 5 and the swinging gear 6 to rotate coaxially but at different speeds, and the moving gear 5 drives the moving mechanism 9, the swinging mechanism 8 and the smashing head 3 around the centerline circumference of the rotating driving body 4 Moving, the rocking gear 6 drives the rocking mechanism 8 to rotate relative to the moving mechanism 9 so that the crushing head 3 swings and crushes the medicine in the cup body 1 .

Lifting and smashing medicine stage: the rotating drive body 4 drives the auxiliary gear 22 to rotate, and the auxiliary gear 22 drives the moving mechanism 24 to lift and make the smashing head 3 lift and smash the medicine.

Generally speaking, the stage of shaking and crushing the medicine and the stage of lifting and smashing the medicine are carried out at the same time, that is, the smashing head 3 is raised and lowered while shaking, so that the complete smashing of the medicine can be achieved with a small number of cycles, and the smashing efficiency is improved. It has been greatly improved, and the lifting speed of the mashing head 3 is lower than the swinging speed of the mashing head 3. Reasonable configuration is more conducive to improving the efficiency of medicine mashing. Specifically, on the one hand, the rotating drive body 4 drives the moving gear 5 through the transmission gear 11 to move along the ring gear 7 with the first rotating speed around the center line of the rotating drive body 4, so that the moving mechanism 9, the rocking mechanism 8 and the mashing Head 3 also moves around the center line circle of rotating drive body 4 with the first rotating speed thereupon, and rotating driving body 4 on the other hand drives rocking gear 6 to rotate around itself with the second rotating speed by main driving pulley 10, from driving pulley 12, transmission belt 13. The axis rotates so that the relative rotation occurs between the rocking mechanism 8 and the moving mechanism 9 so that the crushing head 3 swings to realize drug crushing. At the same time, the swing gear 6 drives the drum 23 to rotate through the auxiliary gear 22. The lifting shaft 25 is driven up and down by the lifting groove 27, and even the lifting plate 26 is driven up and down. The lifting plate 26 drives the moving plate 29 up and down through the mating relationship with the moving plate 29, and finally the telescopic part 34 of the rotating shaft 14 is driven up and down through the lower connecting frame 20. In this way, the smashing head 3 can also be lifted while swinging.

The whole drug smashing can be determined by the working time of the rotating driving body 4 or the number of times the smashing head 3 swings around the cup body 1. For example, the working time of the rotating driving body 4 is t, 30s≤t≤150S, and the rotating driving body 4. Automatically stop after working for t hours, and the crushing of the medicine is finished; or the rotating drive body 4 automatically stops after the smashing head 3 swings n circles around the cup body 1, and the smashing of the medicine is finished. After the crushing head 3 swings around the cup body 1 for one circle, the rotating driving body 4 rotates in reverse until the crushing head swings n circles around the cup body 1, that is, the rotating driving body 4 alternately rotates forward and reverse to realize the alternating positive and negative rotation of the crushing head 3 Swipe to mash the medicine. These control methods are easy to control, and the control accuracy is also high.

The above are only preferred embodiments of the present invention, and it should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present invention, and these should also be regarded as protection of the present invention. None of these will affect the effect of implementing the present invention and the practicability of the patent.
