Description

Technical Field

[0001] The present invention relates to the technical field of floor sweeping vehicles, and particularly relates to a self-cleaning floor sweeping vehicle. Background Art

[0002] Floor sweeping vehicles have the functions of floor sweeping and dust suction, and can clean ground garbage and store garbage. As one of the environmental sanitation equipment, floor sweeping vehicles can be widely used for cleaning trunk roads, municipalities, airport runways, urban residential areas, parks and other roads. Road sweeping vehicles can not only clean garbage, but also purify the air medium on the road, which not only ensures the beauty of the road surface, maintains environmental hygiene, but also maintains the good working condition of the road surface.

[0003] During the process of a floor sweeping vehicle cleaning the road surface, the cleaning brush rotates to clean the road surface. During the cleaning process, the cleaning brush rubs against the ground to scrape off the garbage attached to the ground for cleaning, and then sucks away and collects the cleaned garbage. Since only the cleaning brush is used to clean the garbage, some garbage cannot be sucked away and collected in time during the walking process of the floor sweeping vehicle, which affects the cleaning efficiency. Moreover, the cleaning brush itself is prone to attaching garbage, and if it is not cleaned and cleaned in time during the process of the cleaning brush cleaning the garbage, it will affect the cleaning of the garbage.

[0004] Based on this, a self-cleaning floor sweeping vehicle is proposed here to solve the above problems. Summary of the Invention

[0005] In order to overcome the above technical problems, the purpose of the present invention is to provide a self-cleaning floor sweeping vehicle, and the purpose of the present invention can be achieved by the following technical solutions:

[0006] A self-cleaning floor sweeping vehicle includes a vehicle body. An installation opening facing rightward is provided on the vehicle body. A dustbin with an upper opening is horizontally and slidably inserted into the installation opening. A mounting plate is fixed to the bottom end of the vehicle body. Two symmetrically arranged cleaning soft brushes are rotatably connected to the mounting plate. Sliding blocks are slidably connected to both sides of the mounting plate. The bottom end of the sliding block is fixedly connected with a vertically downward cleaning rod. The bottom end of the cleaning rod is inserted into the gap between the bristles of the cleaning soft brush. An inclined dust suction shell is fixed to one side of the mounting plate. The bottom end of the dust suction shell is provided with an opening. A dust suction pipe is fixedly penetrated through the upper end of the dust suction shell. The dust suction pipe is connected with a dust suction pump for discharging garbage into the dustbin.

[0007] Preferably, two motors are fixedly penetrated through the upper end of the mounting plate. Rotating rods are fixed to the upper ends of the two cleaning soft brushes. Both rotating rods are rotatably connected to the mounting plate. A runner is fixedly connected to the upper end of the rotating rod. A belt is connected between the outer surface of the runner and the output shaft at the upper end of the motor.

[0008] Preferably, a chute is formed on the outer side of the mounting plate. One side of the sliding block is horizontally slidably connected inside the chute. The top end of the sliding block is rotatably connected with a connecting rod, and the other end of the connecting rod is rotatably connected with the upper end of the rotating wheel. A horizontally arranged limiting rod is fixed inside the chute, and the sliding block is slidably connected with the limiting rod.

[0009] Preferably, a support seat is fixedly connected to the outer wall of the dust suction pump. The support seat is fixedly installed inside the vehicle body. The outlet at the upper end of the dust suction pump is fixed with a dust discharge pipe in a J-shaped structure. The upper end of the dust discharge pipe extends to the opening position at the upper end of the garbage bin. An inclined fixed frame is fixed to the outer wall of the mounting plate, and the bottom end of the fixed frame is fixedly connected to the outer wall of the dust suction shell.

[0010] Preferably, a guide rail is fixed to the bottom of the vehicle body. An installation block is horizontally slidably connected inside the guide rail. One side of the installation block is rotatably connected with a rotating plate, and the bottom end of the rotating plate is rotatably connected to the outer surface of the cleaning shovel. A support shaft is fixed to the bottom of the vehicle body, and the upper end of the cleaning shovel is rotatably connected to the support shaft. A second spring is fixed between one side of the installation block and the inner wall of the guide rail.

[0011] Preferably, an opening groove is formed at the top end of the vehicle body. A sliding seat extending out of the vehicle body is horizontally slidably connected inside the opening groove. A first spring is fixed between one side of the sliding seat and the inner wall of the opening groove. A groove is formed through one side of the sliding seat. A fixed shaft is fixedly connected to the outer wall of the garbage bin. A vertically arranged movable rod is rotatably connected to the fixed shaft, and the upper end of the movable rod is inserted into the groove. A handle is fixedly connected to the outer wall of the garbage bin.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. During the movement of the cleaning shovel of the present invention, it can scrape off the garbage attached to the ground that is difficult to clean. Through the rotation of the bristles of the two cleaning soft brushes and the friction with the ground, the ground is further swept in the direction of the dust suction pipe of the garbage bin. Then, through the operation of the dust suction pump, the garbage swept and scraped from the ground is sucked and discharged through the dust suction pipe, so as to clean the ground. During the process of the cleaning soft brush rotating and sweeping the ground, the bristles of the cleaning soft brush collide and rub against the vertically arranged cleaning rod in sequence, so that the garbage attached to the cleaning soft brush shakes off and falls off, and then is sucked into the dust suction shell, automatically cleaning the cleaning soft brush, which is beneficial to the cleaning soft brush of the road sweeper to clean the ground.

[0014] 2. When the motor drives the cleaning soft brush to rotate and clean the floor, the wheel rotates with the cleaning soft brush, driving the connecting rod to move. Under the action of the end of the connecting rod, the sliding block is driven to slide back and forth inside the slide groove, driving the cleaning rod at the bottom of the sliding block to move back and forth. During the rotation and cleaning process of the cleaning soft brush, the bristles of the cleaning soft brush continuously collide with the cleaning rod during the back-and-forth movement, providing a shaking effect for the bristles of the cleaning soft brush, accelerating the falling of garbage attached to the bristles, and facilitating continued cleaning of the floor.

[0015] 3. When the cleaning shovel encounters a bump on the ground that is difficult to shovel, the bump on the ground squeezes the cleaning shovel and rotates it counterclockwise to lift it up, causing the rotating plate to move, pushing the mounting block to slide and compress spring 2 until the cleaning shovel is separated from the bump on the ground. Under the action of spring 2, the cleaning shovel is pushed to rotate clockwise until the bottom end contacts the ground, allowing the cleaning shovel to continue to shovel the garbage attached to the ground and adapt to the bump on the ground.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1 - Figure 6 As shown, a self-cleaning sweeper includes a body 1, a mounting port 11 opening to the right is provided on the body 1, a trash can 8 with an upper opening is inserted into the mounting port 11 for horizontal sliding, a mounting plate 12 is fixed to the bottom end of the body 1, the mounting plate 12 is rotatably connected to two symmetrically arranged cleaning soft brushes 2, both sides of the mounting plate 12 are slidably connected to sliding blocks 13, the bottom ends of the sliding blocks 13 are fixedly connected to a vertically downward cleaning rod 14, the bottom ends of the cleaning rod 14 are inserted into the bristle gap of the cleaning soft brush 2, a dust suction shell 3 is fixed on one side of the mounting plate 12, the bottom end of the dust suction shell 3 is open, a dust suction pipe 26 is fixed through the upper end of the dust suction shell 3, and the dust suction pipe 26 is connected to a dust suction pump 23 for discharging garbage into the trash can 8; when cleaning, the cleaning soft brush 2 and the cleaning brush 2 are connected to the bottom end of the dust suction shell 3. The bottom end of the shovel 4 is in contact with the ground and moves with the movement of the vehicle body 1. During the movement of the cleaning shovel 4, the garbage attached to the ground that is difficult to clean can be scraped off. The bristles of the two cleaning soft brushes 2 (the bristles are flexible and can bend and deform) rotate and rub against the ground, further cleaning the garbage bin 8 attached to the ground in the direction of the dust suction pipe 26, and then the dust suction pump 23 works to suck and discharge the garbage swept and scraped from the ground through the dust suction pipe 26 to clean the ground. In the process of the cleaning soft brush 2 rotating to clean the ground, the bristles of the cleaning soft brush 2 collide and rub with the vertically arranged cleaning rod 14 in turn, so that the garbage attached to the cleaning soft brush 2 is shaken off and falls, and then is sucked into the dust suction shell 3, and the cleaning soft brush 2 is automatically cleaned, which is beneficial for the cleaning soft brush 2 of the sweeper to clean the ground.

[0027] Furthermore, in order to realize the two cleaning soft brushes 2 rotating in opposite directions, cleaning the ground, and sweeping the garbage toward the dust collection shell 3, two motors 27 are fixed through the upper end of the mounting plate 12, and the upper ends of the two cleaning soft brushes 2 are fixed with rotating rods 15, and the two rotating rods 15 are rotatably connected to the mounting plate 12, and the upper ends of the rotating rods 15 are fixedly connected with a rotating wheel 32, and a belt 28 is connected between the outer surface of the rotating wheel 32 and the output shaft of the upper end of the motor 27; when the vehicle body 1 moves to clean the ground, the two motors 27 drive the belt 28 to rotate, driving the two rotating rods 15 to rotate in opposite directions, so that the two cleaning soft brushes 2 rotate in opposite directions to sweep the garbage toward the dust collection shell 3, so that the dust collection pump 23 can quickly suck the cleaned garbage into the dust collection shell 3.

[0028] In this embodiment, in order to make the cleaning rod 14 reciprocate to collide with the bristles of the cleaning soft brush 2 and improve the cleaning effect, a chute 29 is provided on the outer side of the mounting plate 12. One side of the sliding block 13 is horizontally slidably connected inside the chute 29. The top end of the sliding block 13 is rotatably connected with a connecting rod 31. The other end of the connecting rod 31 is rotatably connected with the upper end of the runner 32. A horizontally arranged limiting rod 33 is fixed inside the chute 29, and the sliding block 13 is slidably connected with the limiting rod 33. When the motor 27 works to drive the cleaning soft brush 2 to rotate and clean the ground, the runner 32 rotates together with the cleaning soft brush 2, driving the connecting rod 31 to move. Under the action of the end of the connecting rod 31, the sliding block 13 reciprocally slides inside the chute 29, driving the cleaning rod 14 at the bottom end of the sliding block 13 to move back and forth. During the rotation and cleaning process of the cleaning soft brush 2, the bristles of the cleaning soft brush 2 continuously collide with the cleaning rod 14 during its back-and-forth movement, providing a shaking effect for the bristles of the cleaning soft brush 2, accelerating the falling of the garbage attached to the bristles, and facilitating the continuous cleaning of the ground.

[0029] In order to realize the cleaning and storage of garbage, a support seat 25 is fixedly connected to the outer wall of the dust suction pump 23. The support seat 25 is fixedly installed inside the vehicle body 1. The outlet at the upper end of the dust suction pump 23 is fixed with a dust discharge pipe 24 of a J-shaped structure. The upper end of the dust discharge pipe 24 extends to the opening position at the upper end of the garbage bin 8. An inclined fixed frame 30 is fixed to the outer wall of the mounting plate 12. The bottom end of the fixed frame 30 is fixedly connected to the outer wall of the dust suction shell 3. When the cleaning soft brush 2 rotates to clean the garbage and during the process of scraping and pushing the ground garbage forward, the dust suction pump 23 is powered on to suck the cleaned garbage into the dust suction shell 3, then sent into the dust suction pump 23 through the dust suction pipe 26, and finally sent into the garbage bin 8 through the dust discharge pipe 24 for storage, facilitating the vehicle body 1 to continue cleaning and collecting the ground garbage.

[0030] A guide rail 21 is fixed to the bottom of the vehicle body 1. An installation block 19 is horizontally slidably connected inside the guide rail 21. One side of the installation block 19 is rotatably connected with a rotating plate 18. The bottom end of the rotating plate 18 is rotatably connected to the outer surface of the cleaning shovel 4. A support shaft 22 is fixed to the bottom of the vehicle body 1. The upper end of the cleaning shovel 4 is rotatably connected to the support shaft 22. A second spring 20 is fixed between one side of the installation block 19 and the inner wall of the guide rail 21. When the vehicle body 1 moves, the bottom end of the cleaning shovel 4 contacts the ground, scraping and pushing forward the garbage attached to the ground, and then the garbage is sucked into the dust suction shell 3. When the cleaning shovel 4 encounters a ground protrusion and is difficult to shovel, the ground protrusion squeezes the cleaning shovel 4 to rotate counterclockwise and lift, causing the rotating plate 18 to move and pushing the installation block 19 to slide and compress the second spring 20 until the cleaning shovel 4 disengages from the ground protrusion. Under the action of the second spring 20, the cleaning shovel 4 is pushed to rotate clockwise until the bottom end contacts the ground, enabling the cleaning shovel 4 to continue shoveling the garbage attached to the ground and making the cleaning shovel 4 adapt to the ground protrusion part.

[0031] An opening groove 7 is formed at the top end of the vehicle body 1. A sliding seat 5 extending out of the vehicle body 1 is horizontally and slidably connected inside the opening groove 7. A first spring 16 is fixed between one side of the sliding seat 5 and the inner wall of the opening groove 7. A groove 17 is formed through one side of the sliding seat 5. A fixed shaft 9 is fixed to the outer wall of the garbage bin 8. A vertically arranged movable rod 6 is rotatably connected to the fixed shaft 9. The upper end of the movable rod 6 is inserted into the groove 17. A handle 10 is fixed to the outer wall of the garbage bin 8. The pulling force of the first spring 16 causes the sliding seat 5 to squeeze the movable rod 6 to prevent the movable rod 6 from loosening. By rotating the upper end of the movable rod 6 with force to disengage from the groove 17, the user can hold the handle 10 and pull out the garbage bin 8 outward to clean the garbage stored inside the garbage bin 8, facilitating the subsequent cleaning and storage of ground garbage.

[0032] Working principle: The user drives the vehicle body 1 to move on the ground, causing the cleaning shovel 4 to scrape off the garbage attached to the ground during movement. The motor 27 is energized to rotate, driving the bristles of the two cleaning soft brushes 2 to rotate and rub against the ground, sweeping the garbage attached to the ground in the direction of the suction pipe 26 of the garbage bin 8. Then, through the operation of the suction pump 23, the garbage swept and scraped from the ground is sucked away through the suction pipe 26 to clean the ground. During the process of the cleaning soft brush 2 rotating to clean the ground, the bristles of the cleaning soft brush 2 collide and rub against the vertically arranged cleaning rod 14 in sequence, causing the garbage attached to the cleaning soft brush 2 to shake off and fall, and then being sucked into the suction housing 3 for automatic cleaning of the cleaning soft brush 2, which is beneficial for the cleaning soft brush 2 of the sweeper to clean the ground. When the cleaning shovel 4 encounters a ground protrusion that is difficult to shovel off, the ground protrusion squeezes the cleaning shovel 4 to rotate counterclockwise and lift, causing the rotating plate 18 to move, pushing the mounting block 19 to slide and compress the second spring 20 until the cleaning shovel 4 disengages from the ground protrusion. Under the action of the second spring 20, the cleaning shovel 4 is pushed to rotate clockwise until the bottom end contacts the ground, enabling the cleaning shovel 4 to continue shoveling the garbage attached to the ground and making the cleaning shovel 4 adapt to the ground protrusion part.
