Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Referring to Figure 1-3, a mobile material suction device for suction and discharge vehicles, including a silo 1, legs 2 are fixed at the four corners of the silo 1, a gate valve 3 is fixed on the bottom of the silo 1, and the gate valve 3 is fixed with variable A suction pipe 5 is arranged horizontally below the diameter cone 4 and the variable diameter cone 4, and the side of the suction pipe 5 is connected with a material guide inclined pipe 6 connected with the variable diameter cone 4, and one end of the suction pipe 5 is provided with a joint 7, and the joint 7 The side is provided with the auxiliary blowpipe 8 that communicates with the suction pipe 5, and the auxiliary blowpipe 8 is provided with a ball valve 9, and one end of the suction pipe 5 is connected with an air supply pipe 10, and the two ends of the suction pipe 5 are respectively provided with a one-way valve 11 and a butterfly valve 12. Set the variable diameter cone 4 under the silo 1, set the suction pipe 5 under the variable diameter cone 4, the suction pipe 5 is connected to the variable diameter cone 4 through the material guide inclined pipe 6, and then set the auxiliary blowing pipe 8 on the suction pipe 5 And the air supply pipe 10, thus solved the problems of insufficient power and inconvenient movement in the prior art when suctioning and discharging the car suction for a long distance, and the device is easy to arrange, easy to use and easy to operate.
