Description

Technical Field

[0001] The utility model relates to the field of pulverizers, in particular to a particle pulverizing device for a dust-absorbing road sweeper. Background Art

[0002] A dust-sweeping road sweeper is a device for cleaning dust and other debris on the road. After searching, in the utility model patent with the authorization announcement number CN208944335U, a dust-sweeping pulverizer is disclosed, including a pulverizer body, a base is arranged outside the pulverizer body, a moving handle is installed on one side of the base, and a telescopic shock-absorbing wheel is installed at the bottom of the base, a motor is installed above the base, and a receiving hopper is installed above the base near the other side of the motor, and a box is arranged above the receiving hopper. The utility model is provided with a high-energy ion purifier, which can effectively collect and remove small and medium-sized to submicron-level fine particles in the dust, and a vibration motor is provided to shake off the pulverized material on the inner wall of the pulverizing box through vibration, so as to avoid some pulverized material adhering to the inner wall of the pulverizing box, which will cause bacteria generation for a long time, and a vacuum cleaner is provided, which can be used to process the dust generated during pulverization, reduce the harm caused by dust to the operator, and pollute the working environment.

[0003] However, when the existing vacuum road sweeper is in use, the power source of the vacuum comes from the fan, which causes the dust to pass through the fan when it is sucked by the fan. After entering the fan, the dust and other debris with larger particles will collide with the fan blades due to the suction force, which can easily cause damage to the fan. In addition, some debris often adheres to or embeds on the ground, making it difficult for the fan to suck it. Therefore, it needs to be improved. Utility Model Content

[0004] The utility model aims to provide a particle crushing device for a dust suction road sweeper, which solves the problem that when the existing dust suction road sweeper is in use, large particles of dust and other debris will collide with the fan blades of the fan due to suction after entering the fan, which can easily cause damage to the fan. At the same time, it solves the problem that some debris often adheres to or embeds in the ground, making it difficult for the fan to absorb it.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a particle crushing device for a dust sweeper, comprising a mounting pipe, one end of the mounting pipe is mounted with a connecting pipe 1, the other end of the connecting pipe 1 is connected with an arc pipe, the other end of the arc pipe is mounted with a connecting pipe 2, the interior of the connecting pipe 2 and the interior of the connecting pipe 1 are both provided with crushing mechanisms, and a driving mechanism is installed on the crushing mechanism, a dust hood is mounted at the bottom of the connecting pipe 2, a plurality of scrapers arranged at intervals and inclined are arranged in the bottom of the dust hood, and the ends of the scrapers are fixed to the inner wall of the dust hood.
