In order to solve the problem that the pipeline is easily damaged when being pressed too much, a limiting plate 915 protruding towards the pressing plate 913 is arranged on the accommodating portion 912 below the pressing plate 913 to prevent the pressing plate from being over-pressed to damage the pipeline.

In a further improvement, the pressure plate 913 is connected to a driving device through a connecting rod 916, and a swing connecting member 917 is provided at a connection between the pressure plate 913 and the connecting rod 916. Each valve in this device is used for controlling the break-make of two pipelines 100, and the diameter of two pipelines is different usually, and in order to avoid one of them pipeline excessive pressure when the clamp plate pushes down, limiting plate in this device sets up between two pipelines, when the clamp plate pushes down and contacts two pipelines, because two pipeline diameters are different, the clamp plate can take place to deflect around the swing connecting piece to balanced exerted pressure on two pipelines, the too big damage that leads to of pressure that the clamp plate that avoids one of them pipeline to receive pushed down. The swinging connecting component 917 can be a rotating shaft or a floating joint, and in this embodiment, a floating joint is used.

In a further improvement, the hopper 1 is a conical hopper, so that the medicine falls conveniently. In another embodiment, the taper is inclined at a greater angle to the side wall of the hopper than the angle of repose of the contained medicament to prevent the medicament from adhering to the hopper wall.

As shown in fig. 7, the bottom of the hopper 1 is further modified to be provided with a mesh plate 11. The medicine in the hopper 1 can bond and be the granule of not uniform size along with the storage time is prolonged, and great granule can cause and add medicine inaccurate, easily causes the medicine hole jam moreover, for avoiding the emergence of this problem, this device has installed mesh plate 11 additional in hopper 1 bottom for filter great medicine granule, hold back it in the hopper.

In a further improvement, the side surface of the hopper 1 is provided with a vibrator 12. When the medicine in the hopper is bonded into particles with different sizes, the medicine particles are easy to block the mesh plate 11, and the medicine feeding is not smooth. The device comprises vibrator 12 mounted on the side wall of hopper 1, vibrator 12 vibrates when the valve assembly is opened for dosing, and vibrator 12 stops vibrating when the valve assembly is closed.
