Description

Technical Field

[0001] The invention relates to the technical field of highway cleaning equipment, in particular to an automatic cleaning device for spilled objects on a highway. Background Art

[0002] Highway spillage refers to items that are spilled on the highway during high-speed driving due to irregular cargo transfer, vehicle component damage, objects thrown from windows, accidents, etc., which endanger the safety of other vehicles. There are many types of highway spillage, ranging from small items such as nails, plastic sheets, and stones to large items such as plastic bags, foam boards, cardboard, and tires. Some are scattered over a small area, while others are scattered over several kilometers. Once these items collide and squeeze with high-speed vehicles, they can easily cause traffic accidents, resulting in immeasurable serious consequences.

[0003] According to a highway garbage cleaning device with publication number CN113062249B, the invention can effectively clean dangerous obstacles on the highway road surface and facilitate dumping, which can reduce driving dangers on the highway and improve the safety of the highway;

[0004] When the above technical solution is in use, obstacles on the road surface are collected through scrapers, brushes and conveyor belt assemblies. This cleaning and collection operation of highway garbage is relatively limited and lacks the effect of gathering obstacles, which will cause obstacles to be easily missed from the edge of the collection assembly, making the obstacles on the highway less comprehensive when cleared.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The automatic cleaning device for spilled objects on highways drives the rotating disk to rotate through the motor, so that the gathering plate swings back and forth around the auxiliary mechanism. When the two groups of gathering plates swing inward, the gathering plates will move in the direction of the collection channel with a short displacement, so that the grabbing teeth on the inner wall of the gathering plates will pull and scrape the spilled objects to prevent excessive spilled objects from accumulating on the side of the gathering plates. At the same time, when the gathering plates swing inward, they will drive the scraper plates to move downward, so that the scraper plates will scrape and clean along the road surface, so that comprehensive cleaning can be achieved when gathering the spilled objects on the highway;

[0021] 2. The automatic cleaning device for spilled objects on highways drives the adjustment disk to rotate around the rotating seat in the positive and negative directions by starting the cylinder to extend or shorten, so that the adjustment disk can drive two sets of push-pull arms arranged oppositely to push or pull in opposite directions, so that the two sets of push-pull arms can push and pull two sets of gathering plates to adjust the opening size. The opening size of the two sets of gathering plates can be adjusted according to the spreading range of the spilled objects on the ground, ensuring that the cleaning vehicle does not need to frequently change the driving lane when driving on the highway;

[0022] 3. The automatic cleaning device for spilled objects on highways produces a rolling effect by bringing the friction wheel on the outside of the drainage frame into contact with the ground, so that the friction wheel drives the driving roller to rotate, so that the driving roller drives the shoveling belt to pull and transport the spilled objects along the slope surface on the upper side of the shoveling belt, and the running speed of the shoveling belt is controlled by the driving speed of the cleaning vehicle. By setting the shoveling belt, small-volume and scattered spilled objects can be assisted to be brought into the collection channel, ensuring that the spilled objects are collected more smoothly;

[0023] 4. The automatic cleaning device for spilled objects on highways drives the transmission shaft to rotate through the driving motor, so that the lower grab frames on both sides of the guide wheel seat are flipped up and down, so that the spilled objects on the road surface can be restricted and clamped between the lower grab frame and the upper pressure frame. At the same time, when the two sets of gas spring rods move up along the two forked frames, the two sets of gas spring rods will pull the clamping rods closer to each other and clamp the soft spilled objects, ensuring that the spilled objects are prevented from falling when being grabbed.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 4The present invention provides a technical solution: an automatic cleaning device for spilled materials on a highway, comprising a cleaning vehicle 1, a collecting channel 2 and a gathering plate 4, wherein the cleaning vehicle 1 is loaded with a box-type bucket for collecting debris, the collecting channel 2 is installed on the lower side of the front of the cleaning vehicle 1, a crossbeam frame 3 is installed on the front bumper of the cleaning vehicle 1 by bolts, hydraulic lifting rods 301 are installed on both sides of the crossbeam frame 3, a supporting beam 302 is arranged at the bottom of the hydraulic lifting rod 301, and gathering plates 4 are symmetrically arranged below the two ends of the supporting beam 302, an auxiliary mechanism 9 is connected to the bottom of the hydraulic lifting rod 301, the auxiliary mechanism 9 assists in connecting the supporting beam 302 and the gathering plate 4, a supporting plate 5 is installed in the middle of the supporting beam 302, and the end of the supporting plate 5 away from the supporting beam 302 is rotatably connected to an adjusting disk 6 through a rotating seat 501, and a diagonal tie rod 502 for balancing and reinforcement is connected between the crossbeam frame 3 and the rotating seat 501.

[0043] During specific implementation, the crossbeam frame 3 is installed on the front bumper of the cleaning vehicle 1 with bolts. Then, when in use, the height of the supporting beam 302 is adjusted by starting the hydraulic lifting rod 301 to extend or shorten it, thereby driving the gathering plate 4 to adjust its height, so that the cleaning device can adapt to the adjustment according to the actual installation height required. By connecting the diagonal rod 502 between the crossbeam frame 3 and the rotating seat 501, the gathering plate 4, the support plate 5 and the adjustment plate 6 can be pulled to prevent the gathering plate 4, the support plate 5 and the adjustment plate 6 from tilting.

[0044] See also Figure 1-Figure 5 The upper side of the adjusting disk 6 is rotatably connected to the output end of the cylinder 601 through a column, and the cylinder 601 is rotatably connected to the upper side of the middle part of the supporting beam 302 through a movable sleeve. The upper side of the adjusting disk 6 is rotatably connected with two sets of push-pull arms 602, and the two sets of push-pull arms 602 are arranged opposite to each other on the adjusting disk 6. A motor 603 is installed at one end of the push-pull arm 602 away from the adjusting disk 6, and a turntable 604 is fixed to the bottom output end of the motor 603. An I-pin 605 is connected to the surface of the turntable 604, and the bottom of the I-pin 605 is welded to the upper surface of the gathering plate 4.

[0045] During specific implementation, by starting the cylinder 601 to extend or shorten, the adjusting disk 6 can be driven to rotate around the rotating seat 501 in the positive and negative directions, so that the adjusting disk 6 can drive the two sets of relatively arranged push-pull arms 602 to push or pull in opposite directions, so that the two sets of push-pull arms 602 can push and pull the two sets of gathering plates 4 to adjust the opening size, and then adjust the range of the cleaning device to recover the spilled objects; when the cleaning vehicle 1 is driving on the highway to clean up the spilled objects, the opening size of the two sets of gathering plates 4 can be adjusted according to the spreading range of the spilled objects on the ground, to ensure that the cleaning vehicle 1 does not need to frequently change lanes when driving on the highway.

[0046] See also Figure 3and Figure 4 A strip opening 401 is provided on one side of the gathering plate 4 close to the supporting beam 302, a cleaning brush 402 is installed at the bottom of the gathering plate 4, and the lower surface of the gathering plate 4 is connected with guide bolts 403 at equal intervals, and a scraper plate 404 is slidably connected to the outer side of the guide bolts 403, and grabbing tooth blocks 405 are fixed to the inner wall of the gathering plate 4 at equal intervals, and the bottom edge of the grabbing tooth block 405 is higher than the bottom edge of the cleaning brush 402, and the upper end of the guide bolt 403 is provided with a threaded surface for threaded installation with the gathering plate 4, and the middle surface of the guide bolt 403 is a smooth surface. The guide bolt 403 is used to assist the scraper plate 404 in lifting and sliding, and the scraper plate 404 is composed of angle steel and rubber plate, and the rubber plate of the scraper plate 404 is reinforced to prevent deformation by the angle steel.

[0047] In specific implementation, when the cleaning vehicle 1 is traveling on a highway, the cleaning brush 402 and the scraper plate 404 at the bottom of the gathering plate 4 are brought close to the ground. When the spilled objects on the road are gathered to the middle area between the two groups of gathering plates 4, the scraper plate 404 at the lower side of the gathering plate 4 can gather small-volume spilled objects such as stones and mud blocks, and the cleaning brush 402 at the lower side of the gathering plate 4 can sweep and gather the scattered debris and spilled objects. At the same time, the grabbing tooth block 405 can guide the large-volume spilled objects and ensure that the inner side of the gathering plate 4 has a wear-resistant protective effect.

[0048] By starting the motor 603 on the push-pull arm 602, the turntable 604 is driven to rotate, so that the turntable 604 can drive the I-pin 605 to rotate in a circle around the central axis of the turntable 604, so that the gathering plate 4 can angularly deflect around the auxiliary mechanism 9 through the strip opening 401. Therefore, when the motor 603 drives the turntable 604 to rotate, the gathering plate 4 can produce reciprocating swings around the auxiliary mechanism 9. When the two groups of gathering plates 4 deflect inwardly, the gathering plates 4 will produce a short displacement movement in the direction of the collecting channel 2, so that the grabbing tooth blocks 405 on the inner walls of the gathering plates 4 can produce traction, scraping and shaking of the spilled objects on the road, preventing excessive spilled objects from accumulating on the side of the gathering plates 4, and then cooperating with the forward action of the cleaning vehicle 1, the spilled objects can move quickly toward the collecting channel 2. Since the two groups of gathering plates 4 present an "eight"-shaped structure when gathering materials, they have a centralized guiding effect when gathering materials, which facilitates the cleaning vehicle 1 to efficiently complete the collection of spilled objects.

[0049] See also Figure 4-Figure 6The auxiliary mechanism 9 includes a connecting frame 901, a traction support rod 902 and a steering track 903. The upper end of the connecting frame 901 passes through the supporting beam 302 and is threadedly connected to the hollow hexagonal prism at the bottom of the hydraulic lifting rod 301. The I-shaped section of the connecting frame 901 is connected to the strip opening 401 of the gathering plate 4. The length of the strip opening 401 is greater than the diameter of the connecting frame 901, and the width of the strip opening 401 matches the diameter of the connecting frame 901.

[0050] A traction support rod 902 is vertically welded to the bottom of the connecting frame 901, and an auxiliary wheel is connected to the bottom end of the traction support rod 902. The traction support rod 902 is connected to the steering track 903 through the auxiliary wheel at the bottom end. The steering track 903 is installed in the gap of the scraper plate 404, and the interior of the steering track 903 includes a straight track groove and an inclined track groove.

[0051] In specific implementation, since a strip-shaped opening 401 for sliding the connecting frame 901 is provided on the surface of the gathering plate 4, when the turntable 604 rotates and drives the I-pin 605 to push the gathering plate 4 in the direction close to the supporting beam 302, the gathering plate 4 can slide forward along the connecting frame 901 through the strip-shaped opening 401, so that the gathering plate 4 will have an inward deflection effect. At this time, the gathering plate 4 will drive the scraper plate 404 and the adjustment track 903 to follow and achieve positive movement, so that the auxiliary wheel at the bottom of the traction support rod 902 moves from the inclined track groove of the adjustment track 903 to the straight track groove. Since the height of the auxiliary mechanism 9 cannot be raised or lowered, the adjustment track 903 can be pushed downward by the traction support rod 902, so that the scraper plate 404 moves downward along the guide bolt 403. Therefore, when the gathering plate 4 deflects inward to gather materials, the scraper plate 404 can be in contact with the ground to produce a scraping effect, thereby ensuring more comprehensive cleaning of spilled materials.

[0052] When the turntable 604 rotates and drives the I-pin 605 to pull the gathering plate 4 in the direction away from the supporting beam 302, the gathering plate 4 can slide in the opposite direction along the connecting frame 901 through the strip opening 401, so that the gathering plate 4 will produce an outward deflection effect. At this time, the gathering plate 4 will drive the scraper plate 404 and the adjustment track 903 to follow and achieve reverse movement, so that the auxiliary wheel at the bottom of the traction support rod 902 moves from the straight track groove of the adjustment track 903 to the inclined track groove, so that the adjustment track 903 can be pulled upward by the traction support rod 902, so that the scraper plate 404 moves up along the guide bolt 403. Therefore, when the gathering plate 4 is swung outward and opened, the residual spilled materials between the cleaning brush 402 and the scraper plate 404 can be prevented from being taken away, ensuring that the spilled materials are always between the two groups of gathering plates 4, and can also reduce the loss caused by the long-term scraping friction between the scraper plate 404 and the ground, making the scraper plate 404 more durable.

[0053] See also Figure 7-Figure 11A drainage frame 201 is installed at the lower edge of the opening side of the collecting channel 2, and three groups of auxiliary rollers 201a and a group of driving rollers 201b are movably connected between the two drainage frames 201. The driving rollers 201b extend through the drainage frames 201 and are fixed with friction wheels 201c at both ends. The friction wheels 201c are used to abut against the ground. The outer sides of the three groups of auxiliary rollers 201a are sleeved with shoveling belts 201d. The outer walls of the shoveling belts 201d abut against the driving rollers 201b, and the upper side of the shoveling belts 201d is a sloped surface structure.

[0054] In specific implementation, when the spilled objects move along the two groups of gathering plates 4 to the front end opening position of the collecting channel 2, the friction wheel 201c on the outside of the drainage rack 201 contacts the ground and produces a rolling effect, so that the friction wheel 201c drives the driving roller 201b to rotate, and the driving roller 201b drives the shoveling belt 201d to rotate on the outside of the three auxiliary rollers 201a, so that the shoveling belt 201d can drive the spilled objects to be traction-conveyed along the slope surface on the upper side of the shoveling belt 201d, and the running speed of the shoveling belt 201d is controlled by the driving speed of the cleaning vehicle 1. By setting the shoveling belt 201d, small-volume and scattered spilled objects can be assisted to be brought into the collecting channel 2.

[0055] See also Figure 8-Figure 10 A buffer belt conveyor 202 is installed inside the collecting channel 2, and an inclined scraper belt conveyor 203 is installed on the rear side of the collecting channel 2. A feeding channel is opened in the middle of the cleaning vehicle 1. The scraper belt conveyor 203 is used to transport the spilled materials on the buffer belt conveyor 202 to the box-type truck bed. The opening side of the collecting channel 2 is symmetrically installed with a blocking baffle 204. The blocking baffle 204 is used to block the connecting gap between the gathering plate 4 and the collecting channel 2 to ensure that the spilled materials are concentratedly transported to the collecting channel 2 and prevent the spilled materials from being discharged from the gap between the gathering plate 4 and the collecting channel 2.

[0056] In specific implementation, when the shovel belt 201d sends the spilled matter to the buffer belt conveyor 202 with a small inclination, the buffer belt conveyor 202 can smoothly receive the spilled matter. When the buffer belt conveyor 202 transports the spilled matter to the scraper belt conveyor 203, the spilled matter is concentrated and sent into the box of the cleaning vehicle 1 through the scraper belt conveyor 203 with a larger inclination.

[0057] See also Figure 12-16, a material grabbing mechanism 7 is provided on the lower side of the support plate 5, and the material grabbing mechanism 7 includes a C-shaped guide rail 701 fixed in parallel to the lower side of the support plate 5, a driving motor 702 is installed inside the end of the support plate 5 away from the rotating seat 501, a transmission shaft 703 is fixed to the output end of the driving motor 702, a thread is provided on the surface of the transmission shaft 703, and the transmission shaft 703 is threadedly connected to the threaded hole in the middle of the guide wheel seat 704, the rollers on both sides of the guide wheel seat 704 are docked in the C-shaped guide rail 701, and the two sides of the bottom of the guide wheel seat 704 are connected with a central shaft tube through bearings, and a steering gear disc 705 is fixed on the outer side of the central shaft tube, and a gear rail 706 meshing with the steering gear disc 705 is welded on the outer side of the C-shaped guide rail 701;

[0058] The central axis tube of the guide wheel seat 704 is welded with lower grab frames 707 which are evenly distributed. The multiple lower grab frames 707 are fixed by connecting rods 708. Triangular protrusions are provided on the inner arc surface of the lower grab frames 707. The triangular protrusions can increase the gripping ability and stability of the lower grab frames 707 to prevent the grabbed spilled objects from being blown away by the wind when following the cleaning vehicle 1. An upper pressing frame 8 is fixed to the end of the support plate 5 away from the driving motor 702.

[0059] In specific implementation, the driving motor 702 is started to drive the transmission shaft 703 to rotate forward and reverse, so that the transmission shaft 703 is threadedly transmitted with the guide wheel seat 704 through the threads on the surface, so that the guide wheel seat 704 moves forward and backward along the two sets of parallel C-shaped guide rails 701, so that the guide wheel seat 704 drives the two sets of direction-adjusting gear plates 705 on the central shaft tube to mesh and transmit along the gear rails 706, and then the lower gripper frame 707 on the central shaft tube can be turned in the positive direction;

[0060] When large-scale spilled objects such as plastic bags, foam boards, and cardboard appear on the highway, the person driving the cleaning vehicle 1 controls the driving motor 702 to rotate forward in the vehicle, so that the driving motor 702 drives the transmission shaft 703 and the guide wheel seat 704 to transmit the thread forward, so that the steering gear plate 705 rotates and rolls along the rack 706 toward the direction of the supporting beam 302, and then the steering gear plate 705 can drive the lower gripper frame 707 to flip downward and unfold, and the unfolded lower gripper frame 707 will be close to the ground, so that the two groups of lower gripper frames 707 can shovel up large-scale spilled objects such as plastic bags, foam boards, and cardboard on the road surface;

[0061] When the driving motor 702 is controlled to reverse, the driving motor 702 drives the transmission shaft 703 and the guide wheel seat 704 to transmit in the reverse thread, so that the steering gear plate 705 rotates and rolls along the gear rail 706 in the direction away from the supporting beam 302, thereby driving the lower grab frame 707 to flip upward away from the ground, so that the spilled objects on the road surface can be restricted and clamped between the lower grab frame 707 and the upper pressure frame 8, ensuring that the cleaning vehicle 1 can carry the spilled objects and travel smoothly.

[0062] See also Figure 12-16 , two clamping rods 709 sliding with the connecting rod 708 are arranged between the two groups of lower gripping frames 707, and a plurality of hooks 710 are fixed on the inner arc surface of the clamping rod 709;

[0063] One end of the clamping rod 709 is movably connected to a gas spring rod 711, and the tail end of the gas spring rod 711 is rotatably connected to the reserved opening of the movable seat 712 through a rotating ball. The two ends of the movable seat 712 are installed on the lower side of the C-shaped guide rail 701. A forked bracket 713 is also installed on the lower side of the C-shaped guide rail 701 near the movable seat 712. Two groups of gas spring rods 711 pass through the two forked frames of the forked bracket 713. By setting the gas spring rod 711, when the lower gripper frame 707 is flipped, the gas spring rod 711 can be compressed or extended. The forked bracket 713 is composed of a fixed plate and two inclined forked frames, and the spacing between the upper ends of the two forked frames is smaller than the spacing between the lower ends of the two forked frames.

[0064] When the lower gripper frame 707 is turned down around the central axis tube of the guide wheel seat 704, the gas spring rod 711 at one end of the clamping rod 709 will turn down around the movable seat 712, so that the gas spring rod 711 moves along the upper end of the inclined fork frame to the lower end of the fork frame, so that when the lower gripper frame 707 is close to the ground, the angle between the two groups of gas spring rods 711 becomes larger, and then the output ends of the two groups of gas spring rods 711 will pull the clamping rod 709 away from each other along the connecting rod 708, and the lower gripper frame 707 When the central axis tube of the guide wheel seat 704 is flipped upward, the two groups of gas spring rods 711 will move upward along the two forked frames, so that the angle between the two groups of gas spring rods 711 becomes smaller, and then the output ends of the two groups of gas spring rods 711 will pull the clamping rods 709 along the connecting rod 708 to approach each other, so that when the lower gripper frame 707 and the upper pressing frame 8 clamp and grab the spilled objects, the hooks 710 on the two groups of clamping rods 709 can clamp the soft spilled objects like plastic bags, ensuring that the spilled objects are prevented from falling when being grabbed.

[0065] To summarize, the staff drives the cleaning vehicle 1 on the highway. The staff activates the hydraulic lifting rod 301 to adjust the height of the supporting beam 302 by observing the spilled objects accumulated on the highway, thereby driving the two groups of gathering plates 4 close to the ground, and starts the two groups of motors 603 to drive the two groups of gathering plates 4 to swing back and forth, so that the spilled objects on the road are collected in the middle area of ​​the two groups of gathering plates 4, and when the cleaning vehicle 1 is driving, the spilled objects are concentratedly transported to the box-type truck bed of the cleaning vehicle 1 through the buffer belt conveyor 202 and the scraper belt conveyor 203 in the collection channel 2, ensuring that the cleaning device of the present invention can realize automatic cleaning of spilled objects on the highway.
