Wherein, the thread groove size of the inner chamber of the driving cylinder 5 is larger than the thread-shaped size of the outer surface of the upper end of the fixing rod 8, so that when the weighing is completed, the driving cylinder 5 and the fixing rod 8 are in a separated state, and the accuracy of the balance when the weighing is performed is further ensured.

Wherein, the quantity of dividing the material mouth 7 is three to six, and the quantity of baffle 14 is the same with the quantity of dividing the material mouth 7 and makes and select for use suitable branch material mouth 7 according to required minute dose to divide the medicine chamber through the branch of relative quantity, thereby guaranteed that the phenomenon that mixes together once more can not appear after the medicinal material finishes dividing into medicine.

The using method of the invention is as follows:

centrifuging and distributing the medicines: when the medicinal materials are weighed by a balance, the medicinal materials are firstly placed into the material containing barrel 6, and then the weights are continuously placed into the weight tray 3 from large to small for weighing, so that the material containing tray 4 moves up and down on one side, the material containing tray 4 repeatedly and transversely rotates under the action of the driving barrel 5 and the threaded end of the fixed rod 8, the medicinal materials are thrown out outwards through the material distributing port 7 under the action of centrifugal force, and uniform medicine distribution is completed;

and (3) swing relieving: when the medicinal materials are weighed until the weight difference between the weight pan 3 and the material containing pan 4 is not large, when the balance arm 2 swings under external forces such as vibration or wind power, the movable block 11 moves to the right side under the action of gravity under the action of the inward inclination of the auxiliary cavity 9, and under the action of the magnetic material of the movable block 11, the viscous resistance of the magnetorheological fluid in the speed regulating cavity 10 is large under the action of the increase of the magnetic field, so that the resistance borne by the balance arm 2 when the balance arm 2 rotates is increased, and the balance cannot rotate quickly when the balance arm approaches to a balance state;

when the balance normally weighs, the centrifugal medicine distributing mechanism and the swing relieving mechanism are matched, the threaded ends of the inner cavities of the fixed rod 8 and the driving cylinder 5 and the movable block 11 are close to the right to increase the viscous resistance of the magnetorheological fluid in the speed regulation cavity 10, so that the swing amplitude of the balance during measurement is limited, and further the situation that the noise is generated and the balance arm 2 slowly deforms to influence the service life due to the reciprocating swing of the balance arm 2 with a larger amplitude is avoided.
