Multiple mounting holes are uniformly provided on 11, the first weight linear meter 3-7 is fixed with the first lockplate 3- on one end of the first valve shaft 3-5
12, the first lockplate 3-12 is rotated together with the first weight linear meter 3-7, and the first lockplate 3-12 is equipped with mounting hole.First locking
Plate 3-12 and the first adjustable plate 3-11 carries out position locking by pin 3-13.First adjustable plate 3-11 shown in Fig. 3 is equipped with 3
A mounting hole can be realized 3 grades of adjustment of the first weight linear meter setting angle β, multistage tune can specifically be arranged according to the actual situation
It is whole.Specific adjustment mode are as follows: the first weight linear meter for first rotating the first valve shaft one end, make its upper installing hole with it is a certain on lockplate
On mounting hole is corresponding, the first adjustable plate 3-11 and the first position lockplate 3-12 are locked by pin 3-13.Then symmetrical to adjust
First weight linear meter of whole first valve shaft another side.Finally adjust the first clump weight 3-9 quantity and its on the first weight linear meter
Position, the principle of adjustment is when being in close state when the first valve plate 3-3 and bar 3-2 is contacted, but with finger tip gently one
The first valve plate 3-3 can be opened by pushing away, to guarantee that the material accumulated on a small quantity can open the first valve plate 3-3.
As shown in figure 4, the second weight linear meter 3-8 setting angle β adjustment structure and the first weight linear meter 3-7 setting angle β are adjusted
Structure is identical, specifically: be respectively fixed on the second both ends valve shaft 3-6 the second adjustable plate 3-14, the second adjustable plate 3-14 with
Second valve shaft 3-6 is rotated together, and multiple mounting holes is uniformly provided on the second adjustable plate 3-14, the second weight linear meter 3-8 is close to second
The second lockplate 3-15 is fixed on one end of valve shaft 3-6, the second lockplate 3-15 is rotated together with the second weight linear meter 3-8, and
Two lockplate 3-15 are equipped with mounting hole.Second lockplate 3-15 and the second adjustable plate 3-14 carries out position lock by pin 3-16
It is fixed.Second adjustable plate 3-14 shown in Fig. 4 is equipped with 3 mounting holes, and 3 grades of the second weight linear meter 3-8 setting angle β can be realized
Adjustment, can specifically be arranged multistage adjustment according to the actual situation.Specific adjustment mode are as follows: first rotate the second valve shaft 3-6 one end
The second weight linear meter 3-8, make its upper installing hole it is corresponding with a certain mounting hole on the second lockplate 3-15 on, pass through pin 3-16 will
Second adjustable plate 3-14 and the second position lockplate 3-15 lock.Then the second of the second valve shaft of symmetrical adjustment 3-6 another side
Weight linear meter 3-8.Finally adjust the second clump weight 3-10 quantity and its position on the second weight linear meter 3-8, the principle of adjustment
When being in close state when being contacted for the second valve plate 3-4 and bar 3-2, but gently one is pushed away with finger tip and can open the second valve plate
3-4, to guarantee that the material accumulated on a small quantity can open the second valve plate 3-4.
When work, as shown in Fig. 2, material enters the first feeder pipe 2 by cone 1 under cyclone cylinder, due in Dual airlock valve 3
Layer two valve plates be in closed state, material is accumulated above the first valve plate 3-3 and the second valve plate 3-4, when two valve plates respectively
On accumulating amount when being more than the clump weight weight on respective side weight linear meter, the first valve plate 3-3 and the second valve plate 3-4 are opened, object
Material enters between upper layer valve plate and lower layer's valve plate, since accumulation is reduced above the first valve plate 3-3 and the second valve plate 3-4, the first valve
Plate 3-3 and the second valve plate 3-4 is closed.When material gradually declines, first valve plate 3-3 ' and second valve plate 3-4 ' of the material in lower layer
Top accumulation, when two valve plates respectively on accumulating amount be more than respective side weight linear meter on clump weight weight when, the first valve plate 3-
3 ' and second valve plate 3-4 ' open, material enter the second feeder pipe 4.Material enters the second feeder pipe 4, the first valve plate 3-3 ' and the
Material is reduced above two valve plate 3-4 ', and the first valve plate 3-3 ' and the second valve plate 3-4 ' are closed.That is two valve plate of upper layer and two valve of lower layer
Plate is in the state of alternately opening and closing, and the channel to avoid feeder pipe fully opens and goes here and there wind.Under material continues from the second feeder pipe 4
Row, expanded section 5 enter spreading case 6, and the spreading function through spreading case 6 spreads material into connection air hose 7.
When material occurs uneven, by taking right side is on the high side and left side is on the low side as an example, when right side is on the high side, second valve on upper layer
Plate 3-4 is preferentially opened, and material release is gone down, between upper layer valve plate and lower layer's valve plate.I.e. valve plate can be beaten unilateral side respectively
Acquittal puts material, avoids a certain side valve plate stuck and fails.And when valve plate setting angle α is more than material angle of repose, material
The occurrence of focusing among two valve plates, reducing material partially.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not intended to limit the present invention the foregoing is merely a specific embodiment of the invention
Protection scope, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
