The invention discloses a vacuumizing device for a powder tank truck. The vacuumizing device comprises a truck box body; an air suction hole which is arranged at the top of the truck body body, and the outer portion of the air suction hole is in butt joint with an air suction pump; a push rod which is fixed on the inner wall of the truck body body; a moving block which is fixed at the end part of the push rod; a sealing block which is arranged at the upper part of the moving block in a sliding manner; and a telescopic rod which is vertically arranged in the truck body body, and after the moving block extends, the telescopic rod pushes the sealing block to block the air suction hole. The problems that under the normal condition, the air suction pump needs to be directly connected with the truck box body to vacuumize a truck box, the connection is unstable, and the sealing of the air suction hole is unstable are solved.

    本发明公开了一种粉罐车抽真空装置,包括有车箱体;抽气孔,所述抽气孔设置于车箱体顶部,抽气孔外部与抽气泵对接;推动杆,所述推动杆固定于车箱体内壁;移动块,所述移动块固定于推动杆端部;密封块,所述密封块滑动设置于移动块上部;伸缩杆,所述伸缩杆竖直设置于车箱体内部,移动块伸长后,伸缩杆推动密封块将抽气孔封堵。解决了通常情况下,车厢抽真空需要将抽气泵直接与车箱体连接,这种连接不稳定,抽气孔密封不稳定的问题。
