Description

Technical Field

[0001] The invention belongs to the technical field of track cleaning, in particular to a track and field track cleaning device and a use method thereof. Background Art

[0002] During daily use, the cleanliness of the track directly affects the training effects and competition results of athletes, and is also related to the service life and aesthetics of the venue.

[0003] At present, track and field tracks have a large flow of people and are frequently used. For example, in schools, a large number of students take physical education classes, calisthenics and extracurricular sports every day. Sports clubs and training bases have professional athletes who undergo high-intensity daily training. When sports events are held, there are many contestants, staff and spectators in the track area. The walking and running of these people will bring dirt, dust and other dirt on the soles of their shoes, and there may be garbage such as leaves and food packaging bags left on the track. The traditional way to clean athletic tracks is by hand. Cleaners use brooms, dustpans and other tools to sweep away dust, debris and fallen leaves on the surface of the track section by section. Now, in order to improve cleaning efficiency, vacuum cleaners are also used to clean the surface of the track. However, when using a vacuum cleaner to clean the runway, if there are some leaves or garbage that are larger than the vacuum cleaner's suction port, the vacuum cleaner cannot suck them in and needs to be cleaned manually. At the same time, when the vacuum cleaner sucks in some larger leaves or garbage, the leaves or garbage will cause the suction port to be blocked. When the suction port is blocked, the suction power of the vacuum cleaner will be reduced, thereby reducing the cleaning effect of the runway. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1: Figures 1 to 9 As shown, on the one hand, the present invention discloses a track and field track cleaning device, including a cleaning device; the cleaning device includes two side panels 1; the two side panels 1 are connected to each other via two connecting plates 11 on opposite side ends; and the bottom surfaces of the side panels 1 are both rotatably connected with a rotating wheel 12 below the two connecting plates 11; Two traction rods 13 are fixedly connected to the connecting plate 11 on the right side, and the traction rods 13 are used to be fixed on the driving vehicle; a driving rod is provided on the left side of the traction rod 13, and the driving rods extend to the opposite sides of the two side plates 1; The two side panels 1 are both installed with a collection box 14 on the opposite sides, and the driving rods are both extended into the collection box 14 and rotate on the collection box 14; a first motor 15 is installed on one of the collection boxes 14, and the first motor 15 is used to drive the driving rod; The driving rod is fixedly connected with two spiral pieces 16 arranged in mirror image, and the spiral pieces 16 have opposite spiral directions with the center line of the driving rod as the reference; the two spiral pieces 16 extend into the collecting box 14; the spiral piece 16 passes through one side of the side plate 1 and an arched groove 17 is opened on the side plate 1, and the spiral piece 16 passes through the arched groove 17; The end surfaces of the two side plates 1 opposite to each other below the arched groove 17 are both rotatably connected to a first inclined plate 18, and a rolling ball is rotatably connected to the bottom of the first inclined plate 18; An air box 2 is provided on the left side of the driving rod, and the air box 2 is fixedly connected between the two side plates 1; the bottom contour of the air box 2 is arc-shaped, and a notch 21 is provided; a rotating drum 22 is rotatably connected inside the air box 2, and the rotating drum 22 rotates within the arc-shaped contour of the bottom of the air box 2 and fits the arc-shaped contour; The two sides of the rotating drum 22 are fixedly connected to the rotating rods, and the rotating rods rotate on the side plates 1; the collecting box 14 is equipped with a second motor 23, and the second motor 23 is used to drive the rotating rods; The rotating drum 22 is provided with uniformly arranged air grooves 24; the top of the air box 2 is provided with uniformly arranged air extraction pipes 25, and the other side of the air extraction pipes 25 is installed on the corresponding air extraction mechanism; The air box 2 is provided with an exhaust assembly on one side close to the spiral blade 16, and the exhaust assembly is used to exhaust leaves or garbage that cannot pass through the air groove 24; In this embodiment, the spiral piece 16 is made of elastic rubber material, and the spiral piece 16 is in contact with the ground; Specifically, when cleaning the runway, first fix the traction rod 13 on the driving vehicle, then start the cleaning device, and control the driving vehicle to drive the cleaning device to move along the runway. Since the rotating wheel 12 is provided under the side plate 1, the rotating wheel 12 will rotate along the runway during the movement of the cleaning device. At the same time, since the rotating first inclined plate 18 is connected to a rolling ball, the rolling ball under the first inclined plate 18 also rotates along the runway. More specifically, when the cleaning device is started, the first motor 15 drives the driving rod and the two spiral pieces 16 to rotate. When the rotating spiral pieces 16 come into contact with leaves or other garbage on the runway, the rotating spiral pieces 16 push the garbage to move to both sides of the side plate 1. Since the spiral pieces 16 are made of elastic rubber material, when the spiral pieces 16 located above the first inclined plate 18 rotate, the spiral pieces 16 will be deformed under the obstruction of the first inclined plate 18. At the same time, when the spiral pieces 16 push the garbage to the position of the first inclined plate 18, the garbage will move along the first inclined plate 18 and gradually move through the arched groove 17 into the collection box 14, so that the garbage on the runway can be preliminarily collected. Furthermore, after the cleaning device is started, the exhaust mechanism works. When the exhaust mechanism works, the gas in the air box 2 is extracted, and at the same time, the dust or dirt from the outside is sucked into the air box 2 from the air groove 24 on the rotating drum 22, and then enters the exhaust mechanism through the exhaust pipe 25. At the same time, the second motor 23 drives the rotating drum 22 to rotate counterclockwise in the arc-shaped contour of the air box 2. In the process of the rotating drum 22 driving the air groove 24 to rotate counterclockwise, the passing runway can be sucked, so that the dust and dirt such as mud on the runway can be sucked into the rotating drum 22, and then enter the exhaust mechanism through the exhaust pipe 25. In this process, the mud, dust and other dirt on the runway can be cleaned. At the same time, since the rotating drum 22 rotates in a circular manner, Thus, the air troughs 24 for suction can be replaced cyclically. If some garbage is not pushed into the collection box 14 by the spiral blades 16 and the part of the garbage reaches the bottom of the drum 22, the air troughs 24 for suction can suck the part of the garbage into the drum 22. If some garbage cannot pass through the air troughs 24, since the air troughs 24 are replaced cyclically, when the air troughs 24 for adsorbing the garbage rotate, the remaining air troughs 24 can still suck the runway. At the same time, when the air troughs 24 for adsorbing the garbage gradually turn into the air box 2, the garbage will be gradually pushed down under the obstruction of the air box 2, and then the part of the garbage can be discharged into the collection box 14 through the removal component, thereby preventing the part of the garbage from being located at the drum 22 for a long time and being adsorbed by different air troughs 24. Furthermore, by setting a rotating spiral blade 16, the rotating spiral blade 16 can perform preliminary collection of garbage on the runway, thereby preventing the air groove 24 from being blocked when too much garbage passes through the air groove 24. At the same time, by controlling the counterclockwise rotation of the rotating drum 22, the air groove 24 will be driven to circulate and replace. In this process, different air grooves 24 can be used to suck the runway, so that the dirt on the runway can be extracted, and at the same time, some garbage can be prevented from being adsorbed on the air groove 24, thereby reducing the suction force of the air groove 24 and reducing the cleaning effect of the runway. At the same time, when the air groove 24 is rotated into the air box 2, the air box 2 can push away the adsorbed garbage, and then use the removal component to push the garbage into the collection box 14, thereby avoiding garbage accumulation at the position of the air box 2, thereby affecting the suction process of the air groove 24.

[0019] Embodiment 2: The removal assembly includes a rotating belt 3; the rotating belt 3 is located between the air box 2 and the spiral sheet 16; A feeding slot 31 is provided on the side plate 1 at one side of the rotating belt 3 close to the second motor 23, and one side of the rotating belt 3 extends into the feeding slot 31 and rotates in the feeding slot 31 through a rotating shaft; the feeding slot 31 is connected to the collecting box 14; A second inclined plate 32 is rotatably connected to the side plate 1 below the feed trough 31, and a rolling ball is also rotatably connected to the bottom of the second inclined plate 32; The side of the air box 2 away from the second motor 23 is fixedly connected to the mounting plate 33; a rotating shaft is rotatably connected to the mounting plate 33, and the other side of the rotating belt 3 rotates on the rotating shaft of the mounting plate 33; the rotating shaft is driven by the third motor 34; The outer ring surface of the rotating belt 3 is fixedly connected to the push plates 35 which are evenly arranged, and the side of the push plates 35 close to the arc contour of the air box 2 is in contact with the arc contour of the air box 2, and partially extends to the bottom of the rotating drum 22 and is in contact with the bottom of the rotating drum 22; the push plates 35 will follow the rotating belt 3 through the feed trough 31 and enter the collection box 14; In this embodiment, the bottom of each push plate 35 is fixedly connected to the bristles 36; Specifically, when the cleaning device is working, the third motor 34 will drive the rotating belt 3 to rotate, and the rotating belt 3 will drive the push plate 35 to rotate along the surface of the air box 2 in a circular manner. At the same time, the bristles 36 under the push plate 35 will rotate in a circular manner in accordance with the runway. In the process of the push plate 35 driving the bristles 36 to rotate in a circular manner, the bristles 36 will brush the surface of the runway, thereby pushing away the stubborn mud or dust on the runway, thereby preventing some mud or dust from adhering to the runway and being unable to be sucked away, and at the same time, some dust can be lifted up, so that the air slot 24 can more easily remove the dust. At the same time, since the rotating belt 3 drives the push plate 35 and the bristles 36 to rotate, if some garbage is not pushed into the collection box 14 by the spiral sheet 16, when this part of the garbage passes through the push plate 35 and the bristles 36, the circularly rotating push plate 35 and the bristles 36 will push this part of the garbage to move, and then the push plate 35 and the bristles 36 will drive the garbage to pass through the second inclined plate 32. When the bristles 36 pass through the second inclined plate 32, the bristles 36 will be deformed to adapt to the height of the second inclined plate 32, and then the bristles 36 will push the garbage through the feed trough 31 and fall into the collection box 14; More specifically, if there is still some garbage passing through the rotating belt 3 and reaching the rotating drum 22, since the push plate 35 partially extends to the bottom of the rotating drum 22 and fits with the rotating drum 22, when the garbage is pushed down from the air groove 24 by the air box 2, the circularly rotating push plate 35 and the bristles 36 will push the garbage to move, so that the garbage can be pushed into the collection box 14; During this process, the stubborn dirt can be moved by the circularly rotating push plate 35 and the bristles 36, thereby preventing the dirt from sticking to the runway and being unable to be sucked out. At the same time, the garbage reaching the position of the drum 22 can be pushed into the collection box 14, thereby preventing the accumulation of garbage at the position of the drum 22, thereby affecting the effect of the air groove 24 in sucking out the dirt, and at the same time preventing the garbage from clogging the air groove 24, thereby reducing the cleaning effect of the runway.

[0020] Embodiment 3: The plurality of said exhaust mechanisms include a circular silo 4; the plurality of said circular silos 4 are fixedly connected to the mounting frame 401, and the mounting frame 401 is fixedly connected to the two side panels 1; the other side of each of said exhaust pipes 25 extends to the upper position in the circular silo 4 and is connected to the inside of the circular silo 4; A first disc 41 is rotatably connected in the silo 4; the first disc 41 is provided with evenly arranged fan-shaped grooves 42; and a filter layer 43 is fixedly connected in each fan-shaped groove 42; The second discs 44 are provided on both side end surfaces of the first disc 41 and fit with the first disc 41; the second discs 44 are fixedly connected in the silo 4; trapezoidal grooves 45 are provided on the upper and lower sides of the two second discs 44, and the trapezoidal grooves 45 initially overlap with two of the fan-shaped grooves 42; The second disc 44 on the left side is in contact with the left side wall of the silo 4; the right end surface of the second disc 44 on the right side is fixedly connected to two sector plates 46, and the trapezoidal groove 45 is located in the sector plate 46; The fan-shaped plate 46 is in contact with the right side wall of the silo 4, and the fan-shaped plate 46 separates the two trapezoidal grooves 45; the exhaust pipe 25 extends into the fan-shaped plate 46 above the second disc 44 on the right side; A long rod is fixedly connected to the middle of the first disc 41, and the long rod passes through the second disc 44 on the right and extends out of the silo 4; the long rod is rotatably connected to the second disc 44 on the right; a fourth motor 47 is fixedly connected to the silo 4, and the fourth motor 47 is used to drive the long rod; In this embodiment, an air pump 48 is installed on the mounting frame 401; the inlet end of the air pump 48 extends into the trapezoidal groove 45 above the left second disc 44 and is aligned with the air pump 25; The outlet end of the air pump 48 extends into the trapezoidal groove 45 below the left second disc 44; In this embodiment, a liquid tank 49 is provided at the bottom of each of the round tanks 4, and the liquid tank 49 is installed between the two side plates 1; the liquid tank 49 contains water; The fan-shaped plate 46 located below is fixedly connected to the air outlet pipe 491 at the bottom of the round silo 4, and the air outlet pipe 491 extends to the bottom of the inner cavity of the liquid silo 49; Specifically, when the vacuum mechanism is working, the vacuum pump 48 will vacuum. Since the first disc 41 is located in the middle of the two second discs 44 and fits with the second disc 44, and since the second disc 44 on the left fits with the left side wall of the silo 4, and the second disc 44 on the right fits with the right side wall of the silo 4 through the fan-shaped plate 46, the vacuum pump 48 will vacuum through the filter layer 43 in the uppermost fan-shaped groove 42 when vacuuming, and then the vacuum pipe 25 will vacuum the air box 2 and the drum 22 through the upper fan-shaped plate 46, and then the vacuum pipe 25 will vacuum the air box 2 and the drum 22, and then the external dirt will be pumped into the drum 22 through the air groove 24, and then the dirt will be attached to the filter layer 43 through the vacuum pipe 25 and the upper fan-shaped groove 42, so as to achieve the effect of sucking the dirt; More specifically, during the operation of the air extraction mechanism, the fourth motor 47 is controlled to drive the first disc 41 to cyclically rotate between the two second discs 44, and the first disc 41 will drive the multiple filter layers 43 to cyclically rotate. During the cyclic rotation of the multiple filter layers 43, different filter layers 43 can be made to face the inlet end of the air extraction pump 48 and the air extraction pipe 25. At the same time, the rotating filter layer 43 can take away the adsorbed dirt and transfer it to the position below the first disc 41. Since the outlet end of the air extraction pump 48 is in the trapezoidal groove 45 extending to the bottom of the left second disc 44, the gas blown out of the outlet end of the air extraction pump 48 can blow the filter layer 43 rotating to the bottom, thereby blowing off the dirt adhered to the filter layer 43. Furthermore, the blown dirt will flow into the water tank through the air outlet pipe 491 and then mix with the water in the water tank, thereby preventing the dirt from being raised into dust; By controlling the first disc 41 to drive the multiple filter layers 43 to rotate in a circular motion, the rotating filter layer 43 can bring the dust to the position below the first turntable, and then blown down by the gas blown by the vacuum pump 48 and fall into the water tank. In this process, excessive dust on the filter layer 43 is avoided, thereby reducing the air volume during vacuuming, thereby avoiding a reduction in the runway cleaning effect due to the reduction in air volume, and at the same time avoiding the occurrence of dust.

[0021] Embodiment 4: A round rod is provided on the left side of the air box 2, and the round rod rotates on the side plate 1 and is driven by the fifth motor 51; The round rod is fixedly connected to a brush layer 5 that is evenly arranged; Specifically, when the cleaning device is working, the fifth motor 51 drives the round rod and the brush layer 5 to rotate counterclockwise. The counterclockwise rotating brush layer 5 can brush the running layer. If some dirt on the runway has not been extracted, the counterclockwise rotating brush layer 5 can push the dirt that has not been extracted to the side of the rotating drum 22. When the dirt is pushed to one side of the rotating drum 22, the rotating air groove 24 will suck the dirt again, thereby further improving the cleaning effect of the runway.
