[0048] The top of the bracket 2 is connected to a separator 3, the input port of the separator 3 is connected to a pipe 1 301, the output port of the separator 3 is connected to a pipe 2 302, the bottom of the separator 3 is connected to a lock bucket 303, an upper gate 304 is provided in the upper opening of the lock bucket 303, a lower gate 305 is provided in the bottom opening of the lock bucket 303, a screw extruder 4 is fixedly installed at the bottom of the lock bucket 303, and the bottom of the separator 3 is connected to the screw extruder 4;

[0049] A control cabinet 5 is provided in the middle of the top of the chassis 1, and a centrifugal fan 501 is installed inside the control cabinet 5. A collection bucket 6 is connected to the other side of the top of the chassis 1, and a filter unit 7 is connected to the top of the collection bucket 6. A pulse unit 8 is provided on the top of the filter unit 7, and a pipe 3 801 is connected to the top of the pulse unit 8. The other end of the pipe 3 801 is connected to the air inlet of the centrifugal fan 501.

[0050] A slide rail 9 is fixedly connected to the middle of the bracket 2, a slide sleeve 901 is sleeved on the outer side of the slide rail 9, a slide groove is provided on the top of the slide sleeve 9, two clamping blocks 902 are slidably connected inside the slide groove, a locking bolt 903 is provided between the two clamping blocks 902, and an infrared obstacle avoidance sensor 904 is fixedly connected to one side of the slide sleeve 901;

[0051] The side wall of the chassis 1 is connected to an electric push rod 10, and the output end of the electric push rod 10 is fixedly connected to a dust collecting cover 1001, and one of the openings of the dust collecting cover 1001 is connected to the pipe 1 301;

[0052] In actual use, the roller is placed on the external track, and the driving motor 102 drives the driving wheel 103 to rotate, generating forward power, driving the device as a whole to move along the track, and the centrifugal fan 501 generates negative pressure in the dust hood 1001, so that the external air carries the materials to be cleaned into the dust hood 1001, and is transported through the pipeline 1 301. The materials first enter the separator 3 for separation treatment, and the upper gate 304 is opened. Through the sedimentation effect, the materials fall into the lock bucket 303 under the action of their own gravity, and are temporarily stored in the lock bucket 303, and then the lower gate 305 is opened, and the materials are transported back to the belt conveyor through the screw extruder 4, and then the airflow enters the collection bucket 6 through the pipeline 2 302, and is subjected to secondary separation treatment through the filtering unit 7. The fine materials are separated into the collection bucket 6 for temporary storage through the filtering treatment;

[0053] The electric push rod 10 can drive the dust collecting cover 1001 to move parallel to the ground, thereby achieving a wide range of cleaning, and cleaning work can be carried out deep into the bottom of the belt conveyor, thereby improving the use effect;

[0054] While traveling along the track, obstacles on the route are detected by infrared obstacle avoidance sensor 904. The infrared obstacle avoidance sensor 904 can be installed at an adjustable angle to achieve parallel ground detection and direct ground detection, thereby reducing the risk of collision.

[0055] In this embodiment, Figure 3-Figure 8 As shown, the separator 3 is a conical cylinder, the input port of the separator 3 is located at the top, and the input port of the separator 3 is opened along the tangential direction;

[0056] The airflow in pipe 1 301 flowing to the separator 3 is distributed along the tangential direction, so that the airflow flows along the inner wall of the cylinder of the separator 3, and the material in the airflow is moved along the inner wall of the separator 3 by the centrifugal force. The airflow flows out from pipe 2 302 at the center of the separator 3, thereby achieving a good separation effect.

[0057] The screw extruder 4 is arranged obliquely upward, and the discharge port of the screw extruder 4 is arranged vertically downward;

[0058] The screw extruder 4 can continuously convey the material at the bottom of the separator 3 and discharge the material onto the belt conveyor, thereby achieving long-distance work.

[0059] The filter unit 7 includes a filter cartridge 701, a mounting seat 702, a filter bag 703 and a frame 704. The mounting seat 702 is horizontally mounted at the upper position inside the filter cartridge 701. The filter bag 703 is clamped on the edge of the surface opening of the mounting seat 702. The frame 704 is embedded in the opening of the filter bag 703.

[0060] The filter unit 7 is used to separate fine materials. The materials are separated by the filter bag 703. The materials that cannot pass through the filter bag 703 fall into the collection barrel 6 under the action of natural gravity. The filtered air passes through the pulse unit 8 and is discharged to the outside through the outlet of the centrifugal fan 501.

[0061] The pulse unit 8 includes a pressure-resistant shell 802, an air compressor 803, an air bag 804, a pulse valve 805 and an air duct 806. The pressure-resistant shell 802 is connected to the filter unit 7. The air compressor 803 is fixedly installed on the upper part of the control cabinet 5. The air bag 804 is connected to the pressure output port of the air compressor 803. The pulse valve 805 is installed at the air outlet of the air bag 804. The first end of the air duct 806 is connected to the output port of the pulse valve 805. The second end of the air duct 806 is connected to the inner cavity of the pressure-resistant shell 802.

[0062] The pulse unit 8 is used to clean the filter unit 7. Air is continuously pressed into the air bag 804 through the air compressor 803. The compressed air is discharged into the filter unit 7 through the pulse valve 805 and the air duct 806, so that the airflow impacts the filter bag 703. When the filter bag 703 expands, the material attached to the surface of the filter bag 703 falls off, and the filter bag 703 resumes its filtering function. The material generated by cleaning falls into the collection bucket 6, thereby ensuring the stable and continuous operation of the entire device.

[0063] A solenoid valve 8011 is provided at the connection position between the pipeline 3 801 and the pulse unit 8;

[0064] The solenoid valve 8011 provided on the pipeline three 801 is used to close the pulse unit 8 to prevent the compressed air used in cleaning from impacting the pipeline three 801 and the centrifugal fan 501, thereby ensuring the pulse cleaning effect.

[0065] The slide rail 9 is a rod-shaped structure, and the side wall of the clamp block 902 is provided with an arc groove;

[0066] The slide rail 9 is installed horizontally on the bracket 2, and the slide sleeve 901 is fixed on the slide rail 9 by two clamping blocks 902. The tightness of the clamping block 902 is adjusted by the locking bolt 903. The slide sleeve 901 can move or rotate horizontally relative to the slide rail 9, so that the position and angle of the infrared obstacle avoidance sensor 904 can be adjusted, which is convenient for adjustment according to the working environment. At the same time, the number of infrared obstacle avoidance sensors 904 is selected according to the use environment to ensure that the robot can perform cleaning operations according to the predetermined path and program to achieve a good obstacle avoidance effect.

[0067] A universal wheel 1002 is provided in a circumferential direction below the outer wall of the dust collecting cover 1001;

[0068] The universal wheels 1002 are used to keep a distance between the dust hood 1001 and the ground, so that air can smoothly enter the dust hood 1001, and the universal wheels 1002 facilitate the movement of the dust hood 1001 and the flexible change of the cleaning position.

[0069] The outer wall of the control cabinet 5 is provided with ventilation holes, and the ventilation holes are arranged opposite to the infrared obstacle avoidance sensor 904;

[0070] A single-chip microcomputer is installed inside the control cabinet 5, and is connected to an external power supply device through an umbilical cable to achieve long-distance operation. At the same time, the infrared obstacle avoidance sensor 904 is sprayed through the ventilation holes to make the air flow around the infrared obstacle avoidance sensor 904, thereby reducing impurities floating around the infrared obstacle avoidance sensor 904 and causing inaccurate measurements, thereby ensuring the obstacle avoidance effect.

[0071] The side wall of the chassis 1 is also provided with an oblique support frame 104;

[0072] The diagonal support frame 104 is used to stably support the chassis 1 and the bracket 2, thereby improving the overall stability of the device and reducing the possibility of tipping over.
