Dust suction device of vacuum dust suction vehicle
The invention discloses a dust suction device of a vacuum dust suction vehicle. The dust suction device comprises a dust suction opening shell, the upper end of the dust suction opening shell is communicated with an air inlet pipeline, the lower end of the dust suction opening shell is provided with a dust suction opening, a gap is formed between the dust suction opening and the ground, an return air shell is arranged outside the dust suction opening shell, and a return air channel is formed between the outer wall of a dust suction shell and the inner wall of the return air shell; the lower end of the return air shell is bent towards the interior of the dust suction opening shell to form an upward return air outlet. The device further comprises an air collecting box and a filtering device, the dust suction opening shell is communicated with an inlet of the filtering device through the air inlet pipeline, an outlet of the filtering device is communicated with an inlet of the air collecting box through an air outlet pipeline, and an outlet of the air collecting box is communicated with an inlet of the return air channel. According to the dust suction device of the vacuum dust suction vehicle, a Coanda effect and an entertainment effect are generated through back-flowed high-speed air to drive dust-containing air sucked into the dust suction opening by a draught fan to flow to the air inlet pipeline, the vacuum degree of the dust suction opening is increased, flowing in of outside air into the dust suction opening is facilitated, and the dust suction efficiency is greatly improved.
