The specific meaning of the above terms in the utility model can be understood according to specific situations by those skilled in the art.

As shown in fig. 1, the utility model provides a powder charge device, include: hopper 1, lower medicine 2, valve member 3, weigh 4 and weighing sensor 5, be used for depositing the powder medicine in the hopper 1, lower medicine 2 upper end is connected the discharge gate of hopper 1 bottom, lower medicine 2 lower extreme is connected weigh 4, the medicine passes and enters into in weighing 4 after 2, weigh 4 set up in weighing sensor 5 is last, weigh 4 is connected with the air supply, valve member 3 is used for making lower medicine hole 21 link up or the disconnection in lower medicine 2. Wherein the bottom of the load cell 5 is partially suspended. This device is at the during operation, and valve module 3 is opened, and the medicine hole 21 of giving medicine to the next round of competitions in 2 is link up from top to bottom, and the medicine in the hopper 1 constantly falls in weighing 4, and weighing sensor 5 weighs in real time, and when the medicine weight in weighing 4 reached the default, valve module 3 was closed, and the medicine hole 21 is blocked by intermediate position in the valve module 3, and then the medicine in weighing 4 is blown into the equipment of using medicine by the compressed gas of its intercommunication, accomplishes and send the medicine. Wherein, the upper part of the hopper 1 is fixedly connected to a shell covered on the device.

The weighing in the device only needs to weigh the medicine in the weighing part, and the dosage is small, so that the weighing sensor in the device adopts a small-range weighing sensor, thereby greatly improving the weighing precision.

Meanwhile, the device adds a large amount of solution into trace amount (weighing precision is 0.1g, dosing precision is 0.5g) for multiple times in the past, thereby realizing the purpose of stable solution concentration.

As shown in fig. 2 and fig. 3, a medicine feeding hole 21 which is through from top to bottom is formed in the medicine feeding part 2, a valve hole 22 which is communicated with the medicine feeding hole 21 is formed in the side face of the medicine feeding part 2, a part of the valve assembly 3 extends into the valve hole 22, and the medicine feeding hole 21 is made to be through or disconnected along with the expansion and contraction of the part of the valve assembly 3 in the valve hole 22, so that medicine feeding is completed.

As shown in fig. 2, in a further improvement, the valve assembly 3 includes a plug 31 and a driving member 32, the plug 31 is disposed in the valve hole 22, and the driving member 32 is connected to the plug 31 and is used for driving the plug 31 to extend and contract in the valve hole 22. The output end of the driving piece 32 is connected with the plug 31, and the other end of the driving piece is fixed on the outer wall of the hopper 1 or a shell covered by the device. The driving member 32 is preferably a cylinder, and may be a motor.

In a further improvement, the valve hole 22 is obliquely communicated with the medicine discharging hole 21 along the vertical direction. If the valve hole 22 is horizontal, when the plug 31 extends and contracts in the valve hole 22, the medicine is easy to fall between the valve hole 22 and the plug 31, and the plug 31 is blocked. In this device, in order to avoid this problem, the valve hole is inclined downward to communicate with the medicine discharge hole 21.
