Description

Technical Field

[0001] The present invention relates to the field of road sweeping, and in particular to a water-saving road sweeper. Background Art

[0002] The existing Chinese patent (CN110093891B) is a fully automatic road sweeper:

[0003] The cleaning mechanism collects smaller garbage such as dust and fallen leaves on the road, the protective mechanism clears larger garbage to one side, the lateral movement mechanism moves the flatbed car laterally to clear the garbage on the other side, and the garbage export mechanism automatically exports the collected garbage for collection again. The collected garbage can be automatically exported, and the work efficiency is high.

[0004] Based on the existing technology, when cleaning the park road surface, since the park road surface is partially paved with stone bricks and cobblestones, the stone bricks are easily loosened after being stepped on for a long time, which leads to the stone brick road surface being uneven.

[0017] The advantages and positive effects of the present invention are:

[0018] 1. The brush roller moves up and down to poke the impurities adhering to the road surface, thereby loosening the impurities so that the impurities no longer adhere to the road surface, and the impurities are cleaned by the rotation of the brush roller.

[0019] 2. Impurities adhering to the brush roller are sucked away through two air ducts. At the same time, when impurities are wrapped around the brush roller, the second motor is controlled to start, and the second motor rotates the output shaft to drive the brush roller to rotate. The bristles on the brush roller will touch several levers, thereby scraping off the impurities wrapped around the brush roller through several levers, and sucking away the impurities through the air duct below, thereby removing impurities on the road surface.

[0020] 3. The storage box is moved back and forth up and down, so that the fine salt in the storage box flows out through the two guide plates.

At the same time, the second motor is controlled to rotate, and the rotation of the second motor drives the brush roller to rotate, so that the bristles in the brush roller are close to the two guide plates. When the fine salt flows out from the two guide plates, it will flow onto the bristles in the brush roller, and then be conducted to the road surface through the bristles in the brush roller. This method effectively avoids the problem of insufficient utilization of fine salt due to being blown away in a strong wind environment, thereby effectively utilizing fine salt to melt snow.

[0021] 4. The snow and ice on the road are dispersed by moving the lever, which effectively increases the speed of snow melting. The water on the road is scraped by two scrapers, and the melted water is used to flush the road surface, keeping the road surface clean, thereby effectively saving water resources.

[0022] 5. Hammer the road surface with pressure blocks to squeeze the raised bricks. Since all the pressure blocks are hammered at the same height, the height of the bricks remains consistent, effectively avoiding the problem of uneven bricks and facilitating the subsequent cleaning of the brick road surface. The snow is dispersed and the ice is broken by moving several top blocks, making it easier for fine salt to melt the snow in the later stage, further increasing the melting speed.

[0039] The cleaning unit includes a first fixed plate 201, a slide bar 202, a support plate 203, a first elastic member 204, a connecting frame 205, a door frame 206, a second fixed plate 207, a first motor 208 and a second motor 211; two first fixed plates 201 distributed front and back are fixed to the middle of the left chassis 2; a slide bar 202 is fixed to the upper part of each first fixed plate 201; two support plates 203 distributed front and back are fixed to the left part of the frame 1; each support plate 203 is slidably connected to a corresponding slide bar 202; a first elastic member 204 is sleeved on the outer side of each slide bar 202, and one end of the first elastic member 204 is fixed to the support plate 203, and the other end of the first elastic member 204 is fixed to the slide bar 202; the upper parts of the two slide bars 202 are commonly fixed with a connecting frame 205; the right part of the connecting frame 205 is fixed with a door frame 206 ; The lower part of the portal frame 206 is fixedly connected to two second fixed plates 207 distributed front and back; the first motor 208 is installed on the second fixed plate 207 located in the front; the output shaft of the first motor 208 is fixedly connected to the wind tube 209 below; the two wind tubes 209 are rotatably connected to the two second fixed plates 207; a second motor 211 is fixedly connected to the rear of the portal frame 206; the rotation of the first motor 208 drives the wind tube 209 to rotate, the rotation of the wind tube 209 drives the inclined plate 210 to rotate, and the rotation of the inclined plate 210 drives several driving rods 2101 to rotate, so that several driving rods 2101 are in contact with the road surface, and then when the driving rod 2101 moves, the snow and ice on the road surface are dispersed through the movement of the driving rod 2101, thereby effectively improving the speed of snow melting; the output shaft of the second motor 211 is fixedly connected to the brush roller 212; the brush roller 212 is rotatably connected to the portal frame 206.

[0040] When cleaning: connect the external pump to the conduit 2092 in advance, and then the staff will hold the handrail 3 to push the water-saving road sweeper into the park. Since the park road surface is partially paved with stone bricks and cobblestones, the stone bricks are very likely to become loose after being trampled for a long time, which leads to the stone bricks being uneven. At the same time, the cobblestones are more uneven than ordinary flat roads, and impurities are very likely to remain in the uneven road surface, which makes cleaning more difficult and incomplete. When the four wheels 21 move When the vehicle reaches an uneven road surface, the two left wheels 21 will vibrate, thereby causing the left chassis 2 to vibrate. The vibration of the chassis 2 drives the corresponding first fixing plate 201 and the corresponding sliding rod 202 to move upward, thereby compressing the corresponding two first elastic members 204. The upward movement of the two sliding rods 202 drives the connecting frame 205 to move upward, thereby driving all connected components to move upward, thereby driving the brush roller 212 to move upward. When the two left wheels 21 move to the concave position, the chassis 2 will move downward, thereby driving all connected components to move upward. The brush roller 212 is moved downward, and the brush roller 212 is moved back and forth up and down. At this time, the brush roller 212 moves back and forth up and down to poke the impurities adhered to the road surface, and then the impurities are loosened, so that the impurities no longer adhere to the road surface. At the same time, the second motor 211 is controlled to start, and the second motor 211 rotates the output shaft to drive the brush roller 212 to rotate, and then the impurities are cleaned by the rotation of the brush roller 212. At this time, the impurities will adhere to the brush roller 212 and be taken up by the brush roller 212. At the same time, the external pump is controlled to start, and then The duct 2092 creates negative pressure in the two air ducts 209, and then the impurities adhered to the brush roller 212 are sucked away through the two air ducts 209. At the same time, when impurities are wrapped around the brush roller 212, the second motor 211 is controlled to start, and the second motor 211 rotates the output shaft to drive the brush roller 212 to rotate. The bristles on the brush roller 212 will touch a number of levers 2101, so that the impurities wrapped around the brush roller 212 are scraped off through the several levers 2101, and the impurities are sucked away through the air duct 209 below, thereby removing impurities on the road surface.

[0041] Example 2:

[0042] On the basis of Example 1, according to Figure 7-8As shown, it also includes a snow removal unit; the snow removal unit includes a first fixing frame 301, a storage box 302, a guide plate 3021, a third fixing plate 303, a sliding frame 304, a second elastic member 305, an electric actuator 306, a connecting plate 307, a third motor 308 and a scraper 309; the first fixing frame 301 is fixed to the left chassis 2; the storage box 302 is fixed to the right of the first fixing frame 301; the lower part of the storage box 302 is fixed to two guide plates 3021 distributed up and down, and the two guide plates 3021 are set to an inclined shape, so that the two guide plates 3021 form an angle; two third fixing plates 303 distributed front and back are fixed to the middle of the frame 1 ; Each third fixed plate 303 has a groove in the middle, and a sliding frame 304 is slidably connected in the groove, and a second elastic member 305 is fixed between the sliding frame 304 and the third fixed plate 303; the two sliding frames 304 are fixed to the storage box 302; each third fixed plate 303 has an electric actuator 306 fixedly connected to the lower part; each electric actuator 306 telescopic part is fixedly connected to a connecting plate 307; each connecting plate 307 has a third motor 308 fixedly connected to the lower part; each third motor 308 output shaft is fixedly connected to a scraper 309, the scraper 309 is made of rubber, and the scraper 309 is located below the storage box 302.

[0043] Both guide plates 3021 are provided with grooves, and the grooves correspond to each other one by one, for guiding water.

[0044] The first elastic member 204 and the second elastic member 305 are springs, and the electric actuator 306 is an electric push rod.

[0045] When snow removal is being performed: fine salt is manually loaded into the storage box 302 in advance. When snow and ice accumulate on the road surface, the accumulated snow and ice seriously affect the road cleaning operation. The left chassis 2 vibrates to drive the first fixed frame 301 to move up and down, and the movement of the first fixed frame 301 drives the storage box 302 to move up and down, thereby causing the fine salt in the storage box 302 to flow out through the two guide plates 3021. At the same time, the fine salt is shaken out by the up and down reciprocating manner of the storage box 302, effectively dispersing the fine salt. At the same time, the second motor 211 is controlled to rotate. The rotation of the second motor 211 drives the brush roller 212 to rotate, thereby causing the bristles in the brush roller 212 to approach the two guide plates 3021. When the fine salt flows out from the two guide plates 3021, it will flow into the brush roller 212 The fine salt is then transferred to the road surface through the bristles in the brush roller 212. This method effectively avoids the problem of fine salt being blown away in a strong wind environment, resulting in insufficient utilization, thereby effectively utilizing fine salt to melt snow. At the same time, due to the accumulation of snow and the relatively humid air in the icy environment, water vapor is very likely to enter the storage box 302 during the movement. At this time, since the two guide plates 3021 are set to an inclined shape and form an angle, external water vapor is prevented from entering the storage box 302, and since grooves are provided on the two guide plates 3021, and the grooves correspond one to one, when water vapor stays on the two guide plates 3021, the corresponding grooves are used to guide the water, thereby further preventing water vapor from entering the storage box 302, so that the fine salt remains dry for easy use.

[0046] Since the speed of melting snow by fine salt is slow, the first motor 208 is controlled to rotate to drive the wind tube 209 to rotate, and the rotation of the wind tube 209 drives the inclined plate 210 to rotate, and the rotation of the inclined plate 210 drives several levers 2101 to rotate, so that the several levers 2101 are all in contact with the road surface. Then, when the lever 2101 moves, the snow and ice on the road surface are dispersed by the movement of the lever 2101, thereby effectively improving the speed of snow melting, and then the water-saving road sweeper is made to return. After the snow and ice are melted into water, the two electric actuators 306 are controlled to start and drive the corresponding connecting plates 307 to move downward, thereby driving all connected components to move, thereby causing the two scrapers 309 to move downward and against the road surface, and then the two third motors 308 are controlled to operate, and the output shafts of the two third motors 308 rotate to drive the corresponding scrapers 309 to rotate, so that the water on the road surface is scraped by the two scrapers 309, and the melted water is used to flush the road surface, so that the road surface remains clean, thereby effectively saving water resources.

[0047] Example 3:

[0048] On the basis of the second embodiment, according to Figure 9-10As shown, a pre-cleaning unit is also included; the pre-cleaning unit includes a second fixed frame 401, a fourth motor 402, a transmission shaft 403, a protrusion 404, a pressure block 405 and a top block 406; the second fixed frame 401 is fixedly connected to the middle part of the frame 1; the fourth motor 402 is fixedly connected to the lower part of the second fixed frame 401; the output shaft of the fourth motor 402 is fixedly connected to the transmission shaft 403; the transmission shaft 403 is rotatably connected to the second fixed frame 401; a plurality of protrusions 404 are equidistantly fixed to the lower part of the outer wall of the transmission shaft 403; a plurality of pressure blocks 405 are equidistantly fixed to the upper part of the outer wall of the transmission shaft 403, and the pressure blocks 405 correspond one to one to the protrusions 404; a top block 406 is fixedly connected to the left part of each protrusion 404.

[0049] A counterweight block is provided on the top of the pressing block 405, and the edge of the counterweight block is arc-shaped, which is used to continuously press the stone bricks.

[0050] The lower portion of the top block 406 is configured in an inverted triangle shape to break up ice on the road surface.

[0051] Before cleaning: When the stone brick road surface is uneven, the frame 1 moves to drive the second fixed frame 401 to move, and then drives all connected parts to move, and then drives several protrusions 404 to move. When one of the protrusions 404 moves and touches the protruding stone brick, the fourth motor 402 is controlled to start, and the output shaft of the fourth motor 402 rotates to drive the transmission shaft 403 to rotate. The rotation of the transmission shaft 403 drives all the protrusions 404, all the pressing blocks 405 and all the top blocks 406 to rotate, and then the road surface is hammered by the pressing blocks 405, the protruding stone bricks are squeezed, and because all the pressing blocks 40 5. The height of the hammer is consistent, so that the height of the stone bricks remains consistent, which effectively avoids the problem of uneven stone bricks and facilitates the subsequent cleaning of the stone brick road surface. At the same time, when snow and ice appear on the road surface, the fourth motor 402 is controlled to start, and the output shaft of the fourth motor 402 rotates to drive the transmission shaft 403 to rotate. The rotation of the transmission shaft 403 drives all the protrusions 404 to rotate, and then drives all the top blocks 406 to rotate until they are against the road surface. At this time, the movement of several top blocks 406 disperses the snow and breaks the ice, so that the fine salt can melt the snow in the later stage, further improving the melting speed.

[0052] At the same time, when the pressing block 405 flattens the stone bricks, impurities in the gaps between the stone bricks will be squeezed out. At this time, the first motor 208 is controlled to rotate to drive the air duct 209 to rotate, and the rotation of the air duct 209 drives the inclined plate 210 to rotate. The rotation of the inclined plate 210 drives the plurality of levers 2101 to rotate, so that the plurality of levers 2101 are in contact with the road surface, and then the impurities on the road surface are pre-cleaned by the plurality of levers 2101, and then the plurality of levers 2101 are rotated and reset, and the corresponding air ducts 209 are used to clean the plurality of levers 2101, and the impurities on the plurality of levers 2101 are removed, thereby achieving pre-cleaning.
