Description

Technical Field

[0001] The invention belongs to the technical field of highway sanitation, and in particular relates to a road foreign matter cleaning device for highway maintenance. Background Art

[0002] Expressways are high-grade roads, requiring vehicles to drive at full speed unless necessary. The high volume of traffic on these roads generates significant dust, which can also carry foreign objects such as branches, water bottles, and plastic bags. High-speed vehicles often create high-energy air currents, which propel foreign objects and dust from the road surface into the air. Much of this airflow eventually accumulates on the sides of the road. Without regular cleaning, each passing vehicle displaces dust and foreign objects, disrupting drivers' ability to operate and potentially causing accidents. Currently, cleaning is typically performed by sanitation personnel in sanitation vehicles, which consumes significant energy and labor, and is also dangerous.

[0003] Chinese patent application CN113737698A discloses an automated road cleaning device for highways, in which dust and debris are continuously absorbed by a dust suction cleaning device and stored in a garbage storage structure. The dust suction cleaning device can be moved along the direction of the fence of the highway through the cooperation of the body and the roller. However, since this solution only uses the dust suction cleaning device for cleaning during use, some larger foreign objects cannot be cleaned. If the working end of the dust suction cleaning device is not manually cleaned for a long time, the working end of the dust suction cleaning device may be blocked, thereby affecting the overall cleaning efficiency.

[0004] In view of the problems existing in the current highway sanitation work, it is necessary to further upgrade and optimize the structure of the existing highway cleaning device. Summary of the Invention

[0048] The following will be combined with the accompanying drawings of specific embodiments of the present invention to clearly and completely describe the exemplary embodiments of the present invention. Unless otherwise defined, technical or scientific terms used in the present invention should be given the common meanings understood by people with ordinary skills in the relevant field.

[0049] In the description of the present invention, it should be understood that the expressions “first” and “second” are used to describe the various elements of the present invention and do not represent any limitation on order, quantity or importance, but are only used to distinguish one component from another.

[0050] It should be noted that when one element is expressed as “connected”, “coupled” or “connected” to another element, it may mean that they are directly connected, coupled or connected, but it should be understood that there may be intermediate elements between the two; that is, the positional relationship of direct connection and indirect connection is covered.

[0051] It should be noted that the use of "a" or "an" and similar words does not necessarily indicate a limitation of quantity. "Include" or "comprising" and similar words mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects.

[0052] It should be noted that terms such as "up", "down", "left" and "right" that indicate orientation or positional relationships are only used to indicate relative positional relationships. This is for the convenience of describing the present invention, and does not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0053] See also Figures 1 to 13 As shown, the present application discloses a road foreign matter cleaning device for highway maintenance, comprising a body 1, running wheels fixed to the bottom of the body 1, a garbage storage structure 3 fixed inside the body 1, and a dust suction and cleaning component 4 connected to the garbage storage structure 3. The running wheels in this embodiment are universal wheels 2, and the dust suction and cleaning component 4 is arranged on the side of the body 1 facing the middle of the road, and the dust suction and cleaning component 4 is supported on the ground for walking, and the road is cleaned by the dust suction and cleaning component.

[0054] In order to further improve the cleaning effect of foreign objects on the road, avoid foreign objects that are too large to be cleaned by the vacuum cleaning component, and avoid foreign objects that are too large to block the pipes of the vacuum cleaning component, the present application is provided with a device for cleaning larger foreign objects, specifically including a lifting component 5, a fixed frame 6 and a bucket 7.

[0055] Lifting component 5:

[0056] A first through hole 1a is defined in the side of the machine body 1, communicating with the garbage storage structure 3. A lifting assembly 5 is fixedly disposed on the side of the machine body 1 where the first through hole 1a is defined. The lifting assembly 5 is fixedly disposed above the first through hole 1a. The direction of movement of the working end of the lifting assembly 5 is parallel to the height direction of the machine body 1, and the working end of the lifting assembly 5 is positioned toward the direction close to the universal wheel 2. The lifting assembly can utilize a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. The selected structure is best compatible with the power source provided with the machine body. An electric push rod is preferred, but a drive motor and rack and pinion structure may also be employed. Depending on the specific application, different lifting assembly structures can be selected.

[0057] Mount 6:

[0058] The fixing frame 6 is in an inverted "U" shape as a whole. The fixing frame 6 is fixedly connected to the working end of the lifting assembly 5. The two protruding ends of the fixing frame 6 remain perpendicular to the top surface of the body 1. The line connecting the two protruding ends of the fixing frame 6 remains parallel to the side of the body 1 on which the first through hole 1a is opened. The fixing frame 6 can contact the outer surface of the body 1, so that the fixing frame can maintain a relatively stable posture during sliding and play a guiding role.

[0059] Bucket 7:

[0060] The bucket 7 is in the shape of an "L"-shaped strip as a whole. The bucket 7 is rotatably connected to the fixed frame 6. The bucket 7 is rotatably set between the two raised ends of the fixed frame 6. Due to the inverted U-shaped structure of the fixed frame, the rotation of the bucket in the circumferential direction will not be restricted by the fixed frame. However, since the bucket needs to clean foreign matter, the bucket needs to be constrained accordingly to avoid the bucket from being unable to work; the rotation axis of the bucket 7 in this application is parallel to the direction of the line connecting the two raised ends of the fixed frame 6, and the length direction of the bucket 7 is parallel to the rotation axis of the bucket 7. The back plate of the bucket 7 is in contact with the outer surface of the body 1. At this time, when the bucket 7 is in contact with the body 1, it will not swing circumferentially again, which plays a restraining role.

[0061] During operation, the lifting assembly 5 drives the bucket 7 to switch and move between the first and second work stations through the fixed frame 6. A rotating unit is provided between the bucket 7 and the fixed frame 6, and the rotating unit can adjust the posture of the bucket at a specific work station; specifically, when the bucket 7 is in the first work station, the bottom plate of the bucket 7 is in contact with the ground. At this time, the bottom plate and the back plate of the bucket are constrained, which can play the role of collecting and shoveling foreign matter; a first through hole 1a corresponding to the second work station is provided on the front side of the machine body 1, and the first through hole 1a is communicated with the garbage storage structure 3. When the bucket 7 is in the second work station, the bucket 7 is turned into the first through hole 1a driven by the rotating unit. That is to say, when the material in the bucket 7 reaches a certain amount, by lifting the bucket 7 to the second work station, the rotating unit can make the bucket reverse inward, complete the dumping of the material in the bucket 7, and facilitate the bucket 7 to collect foreign matter again.

[0062] How this application works is:

[0063] When the machine body 1 moves along the direction of the fence of the highway, the lifting assembly 5 works to drive the fixed frame 6 and the bucket 7 to move. The bucket 7 moves downward along the height direction of the machine body 1 to a position close to the ground. Since the outer surface of the back plate of the bucket 7 contacts the outer surface of the machine body 1 at this time, the bucket 7 does not rotate. The opening of the bucket 7 is set along the extension direction of the road. The dust suction and cleaning assembly 4 is a traditional dust suction device. The working end of the dust suction and cleaning assembly 4 is facing the direction close to the center of the road. Auxiliary wheels are fixed below the working end of the dust suction and cleaning assembly 4 to cooperate with the movement of the machine body 1. Specifically, the dust suction and cleaning assembly 4 is also equipped with a dust collection pipe clamped on the machine body 1 and a dust collection cover arranged at the bottom of the dust collection pipe. The auxiliary wheels are universal wheels arranged at the bottom of the dust collection cover. Foreign matter and dust are accumulated on both sides of the road under the influence of the airflow of the vehicle. Some larger foreign matter of the machine body 1 is located near the road fence, that is, on the moving path of the bucket 7. The bucket 7 produces all these foreign matter into the interior of the bucket 7. Then the lifting assembly 5 works again to drive the fixed frame 6 and the bucket 7 to move. In actual application, a long-axis cylinder with a large moving stroke is used, so that the lifting assembly 5 can move the fixed frame 6 to the ground. At this time, the bucket 7 moves upward along the height direction of the body 1 to the first through hole 1a, and then the bucket 7 is controlled to rotate so that the opening of the bucket 7 is set toward the inside of the body 1. The foreign matter in the bucket 7 slides into the garbage storage structure 3 inside the body 1. The smaller foreign matter and dust will be away from the road fence due to the intermittent airflow, that is, on the moving path of the working end of the dust collection and cleaning assembly 4, and then collected into the filter barrel or filter bag of the dust collection and cleaning assembly 4 itself. Compared with the prior art, the dust collection and cleaning assembly of the present application moves smaller foreign matter into the garbage storage structure 3, and the lifting assembly 5, the fixed frame 6 and the bucket 7 gather larger foreign matter in batches, and move the large-volume foreign matter gathered in batches to the garbage storage structure 3, thereby avoiding the situation where the dust collection and cleaning device cannot clean some larger foreign matter, or even the working end of the dust collection and cleaning device is blocked, affecting the overall cleaning efficiency.

[0064] See also Figure 13 As shown: the rotating unit of the present application is a torsion spring 8, there are two torsion springs 8, the torsion spring 8 is fixedly arranged at the connection between the rotating axis of the bucket 7 and the fixed frame 6, and the axis of the torsion spring 8 is parallel to the direction of the rotating axis of the bucket 7.

[0065] The bucket 7 moves along the height direction of the machine body 1 under the operation of the lifting assembly 5. When the bucket 7 moves upward to a position close to the first through hole 1a, the back plate of the bucket 7 is no longer in contact with the outer surface of the machine body 1, and the torsion spring 8 operates to automatically rotate the bucket 7. When the lifting assembly 5 drives the bucket 7 downward, the bottom of the first through hole 1a contacts the bucket 7, causing the bucket 7 to rotate again against the torsion spring 8. Compared with the prior art, the torsion spring 8 of the present application allows the bucket 7 to automatically rotate when it moves to the position of the first through hole 1a, thereby avoiding the need for manual control of the bucket 7 to rotate. A drive member (such as a drive motor, etc.) can also be provided to drive the bucket to rotate, but the torsion spring has better flexibility, lower cost, and is more convenient to arrange.

[0066] See also Figures 9 to 13 As shown: the bucket 7 includes a fixed shell 7a, a load-bearing plate 7b, a pressure sensor 7c and a first spring 7d. The fixed shell 7a is in the shape of an "L"-shaped strip as a whole. The included angle of the fixed shell 7a is 90 degrees. The fixed shell 7a includes two end plates, a bottom plate and a back plate arranged in an "L" shape between the two end plates. The load-bearing plate 7b is slidably matched with the bottom plate of the fixed shell 7a. Specifically, an assembly groove is provided on the bottom plate of the fixed shell (7a), the load-bearing plate (7b) is provided in the assembly groove and slides along the vertical direction of the bottom plate of the fixed shell (7a), the pressure sensor (7c) is fixedly provided in the assembly groove of the fixed shell (7a), and the first spring (7d) is fixedly provided between the load-bearing plate (7b) and the bottom of the assembly groove of the fixed shell (7a).

[0067] When foreign matter continues to accumulate inside the bucket 7, the pressure on the load-bearing plate 7b is continuously transmitted to the pressure sensor 7c. When the pressure on the pressure sensor 7c reaches the rated value, the pressure sensor 7c transmits a signal to the controller, and the controller controls the lifting assembly 5 to work. The bucket 7 then moves along the height direction of the body 1, from the first station at the bottom to the second station corresponding to the first through hole 1a. Compared with the prior art, the load-bearing plate 7b, pressure sensor 7c and first spring 7d of the present application cooperate so that the lifting assembly 5 starts working after the foreign matter in the bucket 7 reaches a certain weight, thereby avoiding the excessive weight of the foreign matter in the bucket 7 causing the force provided by the torsion spring 8 to be unable to drive the bucket 7 to rotate, thereby facilitating the efficient collection of foreign matter in batches.

[0068] See also Figures 9 to 13 As shown: the load-bearing plate 7b is "L"-shaped as a whole, and the bucket 7 also includes a limiting bolt 7e, which is fixedly connected to the fixed shell 7a. The load-bearing plate 7b is provided with a limiting long groove 7b1 that slides with the limiting bolt 7e, and the length direction of the limiting long groove 7b1 is parallel to the sliding direction of the load-bearing plate 7b.

[0069] When the bucket 7 rotates, the load-bearing plate 7b moves under the combined action of gravity and the elongation force of the first spring 7d. When the load-bearing plate 7b moves a certain distance, the limiting bolt 7e contacts the end of the limiting long groove 7b1, and the load-bearing plate 7b stops moving. The limiting bolt 7e and the limiting long groove 7b1 of the present application limit the moving range of the load-bearing plate 7b, thereby avoiding the load-bearing plate 7b from moving too far, causing the load-bearing plate 7b to be stuck on the inner surface of the fixed shell 7a and not contacting the pressure sensor 7c.

[0070] See also Figures 9 to 13 As shown: the bucket 7 also includes two rollers 7f, which are rotatably arranged inside the fixed shell 7a. The axial direction of the roller 7f is parallel to the sliding direction of the load-bearing plate 7b, and the two rollers 7f are respectively arranged at both ends of the fixed shell 7a along the length direction.

[0071] When the foreign matter contacts the two ends of the bucket 7 in the length direction, the foreign matter will contact the surface of the roller 7f. At this time, the roller 7f rotates. As the roller 7f rotates, part of the foreign matter in contact with the roller 7f enters the interior of the bucket 7, and the other part detaches from the two ends of the bucket 7 in the length direction. Compared with the prior art, the roller 7f of the present application makes it possible for the two ends of the bucket 7 in the length direction to either enter the interior of the bucket 7 or release the contact with the bucket 7, thereby avoiding the situation where a large number of foreign matter in contact with the two ends of the bucket 7 in the length direction hinder the movement of the machine body 1.

[0072] See also Figures 9 to 13 As shown, the bucket 7 also includes a roller 7g, a first transmission structure 7h, and a second transmission structure 7i. There are two rollers 7g, which are rotatably arranged inside the fixed shell 7a. The cylindrical wall of the roller 7g protrudes outward from the bottom plate of the bucket 7. The rotating axis of the roller 7g is parallel to the length direction of the fixed shell 7a. To achieve a transmission connection between the roller 7g and the drum 7f, the roller 7g and the drum 7f are arranged in the same plane. The two rollers 7g are respectively arranged at the two ends of the fixed shell 7a along the length direction. One end of the first transmission structure 7h is coaxially connected to the drum 7f. One end of the first transmission structure 7h is coaxially connected to the roller 7g, and the other end of the first transmission structure 7h is connected to the other end of the second transmission structure 7i. The roller 7g and the drum 7f achieve synchronous transmission.

[0073] Specifically, since the roller 7g is in contact with the ground and rotates, the roller 7g transmits the rotational force to the second transmission structure 7i through the first transmission structure 7h, and the second transmission structure 7i transmits the rotational force to the roller 7f, so that the roller 7f rotates spontaneously. Compared with the prior art, the roller 7g, the first transmission structure 7h and the second transmission structure 7i of the present application cooperate so that the roller 7f will automatically rotate when the body 1 moves, thereby avoiding the situation where the weight of the foreign object itself is too large and the roller 7f cannot rotate through friction with the foreign object.

[0074] See also Figures 9 to 13 As shown: the first transmission structure 7h and the second transmission structure 7i are the same. The first transmission structure 7h includes a first gear 7h1, a second gear 7h2, a transmission belt 7h3 and a bevel gear 7h4. The first gear 7h1 is transmission-connected to one end of the transmission belt 7h3, the second gear 7h2 is transmission-connected to the other end of the transmission belt 7h3, the bevel gear 7h4 is coaxially fixedly connected to the second gear 7h2, the first gear 7h1 of the first transmission structure 7h is coaxially fixedly connected to the roller 7f, the first gear 7h1 of the second transmission structure 7i is coaxially fixedly connected to the roller 7g, and the bevel gear 7h4 of the first transmission structure 7h is transmission-connected to the bevel gear 7h4 of the second transmission structure 7i.

[0075] The rotation of the roller 7g drives the first gear 7h1 on the second transmission structure 7i to rotate, and the second gear 7h2, the bevel gear 7h4 and the first gear 7h1 of the second transmission structure 7i maintain synchronous rotation through the transmission belt 7h3, and the bevel gear 7h4 in the second transmission structure 7i drives the bevel gear 7h4 in the first transmission structure 7h to rotate, and the bevel gear 7h4, the second gear 7h2 and the first gear 7h1 in the first transmission structure 7h maintain synchronous rotation through the transmission belt 7h3, and the first gear 7h1 in the first transmission structure 7h drives the roller 7f to rotate. Compared with the prior art, the first gear 7h1, the second gear 7h2, the transmission belt 7h3 and the bevel gear 7h4 of the present application ensure the transmission stability between the roller 7f and the roller 7g, thereby avoiding the situation that the roller 7f cannot stably cooperate with it to rotate when the roller 7g rotates.

[0076] See also Figures 9 to 13 As shown: the bucket 7 also includes a fixed plate 7j, the number of the fixed plates 7j is two, the fixed plates 7j are in a "V" shape as a whole, the fixed plates 7j are fixedly arranged inside the fixed shell 7a, and the two fixed plates 7j are respectively arranged at both ends of the fixed shell 7a along the length direction. The fixed plates (7j) are arranged in a one-to-one correspondence with the end plates of the fixed shell (7a), and an assembly cavity is formed between the fixed plates and the end plates. The roller (7f), the roller (7g), and the synchronous transmission mechanism are arranged in the corresponding assembly cavity to protect their structures.

[0077] Foreign objects that move into the fixed shell 7a continue to accumulate. As the foreign objects continue to accumulate, the foreign objects inside the fixed shell 7a continue to squeeze toward the two ends of the fixed shell 7a along the length direction. At this time, due to the presence of the fixed plate 7j, these foreign objects will not be able to move further after moving a certain distance, ensuring that the foreign objects will not affect the normal operation of the first transmission structure 7h and the second transmission structure 7i. Compared with the prior art, the fixed plate 7j of the present application limits the movement range of foreign objects inside the fixed shell 7a, thereby preventing the foreign objects from moving toward the two ends of the length direction of the fixed shell 7a and contacting the first transmission structure 7h and the second transmission structure 7i as the foreign objects continue to accumulate.

[0078] See also Figures 6 to 8 As shown: a second through hole 1b is provided on the side of the body 1 away from the first through hole 1a, and the body 1 also includes a sliding plate 1c and a second spring 1d. The sliding plate 1c is slidably arranged on the side of the body 1 where the second through hole 1b is provided. The sliding direction of the sliding plate 1c is parallel to the height direction of the body 1. The sliding plate 1c is slidably arranged above the second through hole 1b. The second spring 1d is arranged between the sliding plate 1c and the body 1, and the axis of the second spring 1d is parallel to the height direction of the body 1.

[0079] By pushing the sliding plate 1c to slide, the sliding plate 1c moves upward along the height direction of the body 1, and the second spring 1d is compressed. At this time, the second through hole 1b is not blocked, and the staff grabs the garbage storage structure 3 and slides it outward, so that the garbage storage structure 3 is taken out from the inside of the body 1. When the garbage inside the garbage storage structure 3 is cleaned, it is stuffed into the inside of the body 1 again. At this time, the sliding plate 1c is released, and the second spring 1d is released from the compressed state and pushes the sliding plate 1c to move downward along the height direction of the body 1. The sliding plate 1c blocks the second through hole 1b to fix the garbage storage structure 3. Compared with the prior art, the second through hole 1b, sliding plate 1c and second spring 1d of the present application cooperate to make the garbage storage structure 3 inside the body 1 easy to take out, thereby avoiding the garbage storage structure being filled with garbage during long-term work, resulting in no place for the garbage cleaned by the subsequent bucket 7 and dust cleaning assembly 4 to accumulate. The garbage storage structure (3) in the present application includes a first storage bucket corresponding to the first through hole (1a) and a second storage bucket corresponding to the dust collection and cleaning component (4), which are used to collect foreign matter or dust entering in different ways. The second storage bucket can also be a filter bag provided with the dust collection and cleaning component. The first storage bucket is an open material bucket to facilitate receiving foreign matter entering from the first through hole.

[0080] See also Figures 6 to 8 As shown: the body 1 also includes a warning light 1e, which is fixedly arranged on the top surface of the body 1.

[0081] By connecting the warning light 1e to the power supply inside the body 1, the warning light 1e is started when the body 1 drives the bucket 7 and the dust collection and cleaning component 4 to work. At this time, the warning light 1e continuously emits light as the body 1 works, thereby serving as a reminder and warning to the driver. Compared with the prior art, the warning light 1e of the present application makes it easy for the driver to find the body 1 when it is working, thereby avoiding the driver's failure to observe the existence of the body 1 at a distance due to lack of concentration when driving the vehicle on a highway.
