[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example

[0017] See also Figure 1The utility model provides a dust suction device for a sanitation vehicle, comprising a mounting frame 1, a dust suction box 2, a column 3, a belt loop 4, a connecting pipe 5, an electric cylinder 6 and a distance measuring device 7. The two ends of the electric cylinder 6 are respectively fixed to the mounting frame 1 and the dust suction box 2 to realize that the dust suction box 2 is connected to the mounting frame 1. A suction port 201 is arranged at the front end of the dust suction box 2. A baffle 203 is hinged at the suction port 201 of the dust suction box 2. The area of ​​the baffle 203 is smaller than that of the suction port 201. The baffle 203 is used to block the suction port 201 to ensure the suction force of the vacuum cleaner at the suction port. When the baffle 203 contacts the stone, the baffle 203 is movable and will not affect the cleaning of the stone.

[0018] A collecting box 202 is provided at the rear end of the dust box 2, and an openable movable door 204 is provided on the side of the collecting box 202 of the dust box 2. The column 3 is laterally embedded in the bottom of the dust box 2, and the column 3 and the dust box 2 form a rotating pair. One end of the belt loop 4 is located at the suction port 201 in the dust box 2, and the other end of the belt loop 4 is located above the collecting box 202 in the dust box 2. A roller 401 for tightening the belt loop 4 is provided in the dust box 2. The bottom surface of the belt loop 4 contacts the top of the column 3, and the belt loop 4 can be driven by the rotating column 3. The connecting pipe 5 is installed on the mounting frame 1, and one end of the connecting pipe 5 is connected to the vacuum cleaner on the sanitation vehicle and the other end is connected to the top of the dust box 2. The distance measuring device 7 is installed on the mounting frame 1 to measure the distance to the ground.

[0019] The distance measuring device 7 refers to a device capable of realizing distance measurement, which belongs to the prior art content and is known to those skilled in the art. Therefore, the specific structure and working principle of the distance measuring device 7 are not further explained. In implementation, the technicians can use a radar ranging module to measure the distance to the ground.

[0020] The control method of the present invention is to realize automatic control through an external controller. The electric cylinder 6 and the distance measuring device 7 are connected to and controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and circuit connection in detail.

[0021] Working principle: Use bolts to fix the mounting frame 1 on the sanitation vehicle and connect the connecting pipe 5 to the vacuum cleaner of the sanitation vehicle. The sanitation vehicle drives the dust box 2 to move on the road. During the process, the column 3 is pressed against the ground and rotated by the friction force to reduce the friction between the bottom surface of the dust box 2 and the ground. During the movement of the sanitation vehicle, the dust on the road surface can be sucked into the dust box 2 from the suction port 201, and finally sucked away by the vacuum cleaner through the connecting pipe 5.

[0022] The bottom surface of the belt loop 4 is in contact with the column 3 driven by the ground to rotate, so the belt loop 4 can run on the roller 401. When the suction port 201 contacts the stone, the stone will be scooped up by the suction port 201 and enter the dust box 2 and fall on the belt loop 4. The stone moves synchronously with the belt loop 4 until it moves to the end of the belt loop 4, and then the stone falls from the belt loop 4 and falls into the collection box 202 for unified recovery.

[0023] When the sanitation vehicle is moving, the distance measuring module can measure the distance between the mounting frame 1 and the ground, and then, with the participation of an external controller, the vertical position of the dust box 2 can be changed by extending and retracting the movable end of the electric cylinder 6, so that the main body at the bottom of the dust box 2 can be in contact with and close to the ground, and at the same time, it helps the suction port 201 to shovel up foreign objects such as stones.

[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
