Abstract
The invention discloses a pressure regulating device and a street sweeper. The pressure regulating device comprises a base, an upper pressure regulating piece and a lower pressure regulating piece, wherein the base comprises a base body and a convex edge, the base body comprises an air inlet and air outlet, and the convex edge is arranged around the outer edge of the air inlet; the upper pressureregulating piece is connected with the convex edge through a sliding rod and is glidingly arranged at the upper end of the sliding rod, a spring is clamped between the upper pressure regulating pieceand the convex edge and is coaxially arranged on the sliding rod in a sleeved mode, and a plug is arranged at the upper end of the sliding rod; the lower pressure regulating piece is suspended below the air outlet and seals and blocks the air outlet; and the lower pressure regulating piece is fixedly connected with the upper pressure regulating piece. The pressure regulating device solves the technical problem in the prior art that a dustbin has the risk of being damaged by the outside atmosphere and the door of the dustbin is difficult to open due to the large pressure difference between inside and outside of the dustbin of the street sweeper during working.
Description
technical field [0001] The application relates to the field of air pressure, in particular to a pressure regulating device and a sweeping vehicle. Background technique [0002] Sweeping vehicle is a garbage sweeping vehicle that combines sweeping function and dust collection function. Because of its advantages of high work efficiency, low cleaning cost, high safety performance and high economic return rate, it has been widely used in the cleaning of roads in large, medium and small cities. Work. [0003] The pure suction sweeper includes a vacuum system, a dustbin, an electric controlsystem and a walking system. The sweeper uses negative pressure to absorb garbage. After the vacuum system starts to work, the air pressure in the garbage bin begins to decrease, and the pressure difference between the inside and outside of the garbage bin gradually increases. When there is a large pressure difference between the inside and outside of the dustbin, the wall of the dustbin will...
