Embodiment
With reference to specific embodiment, content of the present utility model is described in further detail：
In order to reach the purpose of this utility model, Fig. 1 is a kind of the first valve state master of embodiment of the utility model
View.Solid bulk material 6 is stored in hopper 1, possesses material cavity 2 under hopper 1, and the directing material 6 of material cavity 2 discharges.Material
The side of chamber 2 is provided with oscillatory valve 3, and oscillatory valve 3 is made up of two swing arms of the first swing arm 3a and the second swing arm 3b, the first swing arm 3a with
Second swing arm 3b is structure as a whole and mutually angled, the first swing arm 3a and the second swing arm 3b one class V-shaped of composition, the
One swing arm 3a length is more than the second swing arm 3b.First swing arm 3a lower end possesses the first catch 4a, the second swing arm 3b lower end
Possesses the second catch 4b.First catch 4a, the second catch 4b may be inserted into or pull out material cavity 2, the first catch 4a and second
The space separated between catch 4b is second material chamber 2b, and the material 6 that space may store in second material chamber 2b is i.e. once fixed
Measure the volume of material, the material cavity on the second catch 4b forms first material chamber 2a.The top of oscillatory valve 3 connects with oscillating motor 5
Connect, oscillating motor 5 gives the oscillatory forces of left and right in oscillatory valve such as figure.
Oscillatory valve 3 is turned left swing from the right side in Fig. 1, and the first catch 4a is first inserted and closed material cavity 2, and the second catch 4b is not
Material cavity 2 is inserted, now, because gravity is filled with material 6 between first material chamber 2a and second material chamber 2b.
Fig. 2 is a kind of second of valve state front view of embodiment of the utility model.Oscillatory valve 3 continues swing of turning left,
Second catch 4b has also been inserted and has been closed material cavity 2, and now the first catch 4a does not detach material cavity 2 yet, this moment the first catch 4a
