The working principle is as follows:
the invention improves the cleaning and taking device in the negative pressure car cleaner of the prior art CN202021301097.7 utility model, the mounting plate 4 is mounted at the bottom end of the lifting carriage 1 through the rotating mechanism 3, thereby being capable of rotating at a certain angle, when the car cleaning operation is carried out, when the unloading of the material at one side in the carriage is completed, the material taking device can be rotated 180 degrees, the components on the mounting plate 4 are driven to rotate 180 degrees together, the material at the other side in the carriage is cleaned and collected, the cost input is reduced, the weight of the material taking device is lightened, and the load of the equipment is reduced.
Under the cooperation of the spiral material collector 5, the transverse rolling brush 6 and the movable disc brush mechanism 7, materials can be sufficiently moved towards the direction of the feeding pipe 2, and the materials are moved to the feeding port at the bottom end of the feeding pipe 2 to the maximum extent, so that negative-pressure suction and collection are realized.
When the movable disc brush mechanism 7 collects materials, the generated dust is adsorbed by the dust hood 8 rotatably mounted above the movable disc brush mechanism 7 and enters the material suction sleeve 37 through the first dust collecting pipe 81 to be collected; the dust generated by the transverse rolling brush 6 cannot diffuse upwards under the blocking of the mounting plate 4, so that the dust is prevented from diffusing outwards from the inner pipe 32; the dust collection pipe 9 arranged on one side of the mounting plate 4 opposite to the movable disc brush mechanism 7 can collect dust generated by the transverse rolling brush 6 and prevent the dust from diffusing to the outside, and because the other two sides of the mounting plate 4 are attached to the inner walls of the two sides of the carriage in operation, the dust cannot diffuse outwards from the other two sides of the mounting plate 4, thereby realizing effective dust suppression.
The dust hood 8 is only under the action of gravity under the action of no external force, the stop lever 84 keeps an included angle of 45 degrees with the vertical direction under the action of the limiting rod 85, when the movable disc brush mechanism 7 is close to the carriage wall in the cleaning process, the roller 86 arranged on the side edge of the dust hood 8 through the pin shaft is contacted with the carriage wall, under the condition that the movable disc brush mechanism 7 is continuously close to the carriage wall, the dust hood 8 starts to rotate, the included angle between the dust hood and the vertical direction is gradually reduced, when the movable disc brush mechanism 7 is completely close to the carriage wall, the included angle between the dust hood 8 and the vertical direction reaches the minimum value, and is more than 15 degrees, after the movable disc brush mechanism 7 finishes the collection of the corners of the compartment wall, the movable disc brush mechanism starts to retreat, at the moment, the rollers 86 on the side edges of the dust hood 8 gradually separate from the compartment wall, and finally, the included angle between the dust hood 8 and the vertical direction is recovered to 45 degrees under the action of no external force.
Under the cooperation of the spiral material collector 5, the transverse rolling brush 6 and the movable disc brush mechanism 7, materials can be sufficiently moved towards the direction of the feeding pipe 2, and the materials are moved to the feeding port at the bottom end of the feeding pipe 2 to the maximum extent, so that negative-pressure suction and collection are realized.
