In shaft, lobus dexter piece is fixed on right spindle, left rotary shaft, right spindle one end torque input is formed by stretching out on the outside of gate seat
End, pneumatic gate valve further include be set to shaft to the left on the outside of gate seat, right spindle torque input end input torque cylinder
Driving mechanism.
Pneumatic gate valve according to claim 1, it is characterised in that: the cylinder driving mechanism includes and left rotary shaft
The second cylinder the first connected cylinder of torque input end transmission and be connected with the transmission of the torque input end of right spindle.
It is fixed with the first connecting lever on the torque input end of left rotary shaft, second is fixed on the torque input end of right spindle and is turned
Arm, the first cylinder, second cylinder or so arrangement, the piston rod of the first cylinder are hinged and connected with the first connecting lever, the work of the second cylinder
Stopper rod is hinged and connected with the second connecting lever.
The cross sectional shape in powder channel is circle, and lobus sinister piece, lobus dexter piece are the semicircle vane plate being arranged symmetrically.
The left channel part, right channel part inner hole be along the gradually smaller taper in powder carry direction aperture
Hole.
The utility model has the following beneficial effects: powder barrier is by powder channel partition at left channel part and the right side in the present invention
Channel part, left channel part are controlled by the lobus sinister piece being correspondingly arranged with left channel part, and right channel part is due to right channel part
Divide the lobus dexter piece control being correspondingly arranged, if there is the situation in flour blocking powder channel, by being located at the cylinder on the outside of gate seat
Driving mechanism drives corresponding blade back and forth to overturn breaing up of will blocking, so that flour be avoided to block at pneumatic gate valve.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment of the utility model；
Fig. 2 is the structural schematic diagram of lobus sinister piece and lobus dexter piece in Fig. 1；
Fig. 3 is the cooperation schematic diagram of cylinder driving mechanism and lobus sinister piece, lobus dexter piece in Fig. 1.
Specific embodiment
A kind of implementation of pneumatic gate valve is for example shown in Fig. 1 ~ 3: the gate seat 2 including being provided with powder channel, powder channel
For circular channel, it is provided in the middle part of powder channel along the powder barrier 14 extended perpendicular to powder carry direction, circular channel
The periphery of powder barrier is provided with tapered sleeve 12 on inner wall, powder barrier leads to powder channel partition at left channel part 11 and the right side
Road part 3, left channel part 11, right channel part 3 inner hole be along the gradually smaller taper in powder carry direction aperture
Hole.Pneumatic gate valve further includes the lobus sinister piece 15 of arrangement corresponding with left channel part and the lobus dexter piece with the corresponding arrangement of right channel part
1, the axis left rotary shaft 13 vertical with powder carry direction and right spindle 6 are rotatably equipped in powder barrier, lobus sinister piece 15 is fixed
In in left rotary shaft 13, lobus dexter piece 1 is fixed on right spindle 6, and lobus sinister piece, lobus dexter piece are the semicircle vane plate being arranged symmetrically.It is left
Shaft, right spindle one end be to form torque input end by stretching out on the outside of gate seat, pneumatic gate valve further includes being set to gate
Shaft to the left, the cylinder driving mechanism of the torque input end input torque of right spindle in seat outside.In the present embodiment, cylinder driving
Mechanism includes the first cylinder 10 being connected with the transmission of the torque input end of left rotary shaft 13 and is driven with the torque input end of right spindle
The second connected cylinder 4, is fixed with the first connecting lever 8 on the torque input end of left rotary shaft, fixed on the torque input end of right spindle
There are the second connecting lever 7, the first cylinder, second cylinder or so arrangement, the piston rod 9 and the first connecting lever of the first cylinder are hinged and connected and reality
Now rotating shaft transmission, the piston rod 5 and the second connecting lever of the second cylinder are hinged and connected and realize rotating shaft transmission to the right to the left.
