When rail vehicle needs stucco, the motor 7 turns an angle as needed, to drive the eccentric rotary
Part 6 rotates, and then the moving member 5 overcomes the elastic force of the elastic component 8 to move right under the promotion of the eccentric rotary components 6
Certain distance, then opening the quicksand hole 3 to required size, then makes the sand grains in the sand storage cavity room 2 through quicksand hole 3
Quantitative outflow；
Compressed gas is conveyed to the air admission hole 12 by the air compression plant of outside, so that compressed gas is flowed into institute
State in guide pipeline 10 and form negative pressure, extraneous air is flowed rapidly into through gas port 13 to the inlet plenum 11,
To drive the sand grains from the quicksand hole 3 output to be sequentially expelled to the body 1 through the guide pipeline 10 and the sand export 9
Outside, so far complete stucco operation.
When rail vehicle needs to stop stucco, the motor 7 rotates backward, and then drives the eccentric rotary components 6 anti-
To rotation, then make the moving member 5 self-return under the elastic force effect of the elastic component 8, so that the quicksand hole 3 is close
Envelope；
Continue to convey compressed gas to the air admission hole 12 by the air compression plant of outside, so as to remain in described lead
Sand grains in feed channel 10 and the grade sand grains transfer pipeline of the sand export 9 is taken out of to the outside of the body 1 by compressed gas, is entered
And ensure the phenomenon that will not be blocked in sand grains course of conveying.
