Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular to an automatic anti-skid aggregate recycling device. Background Technology

[0002] Colored anti-skid pavement is a high-friction, thin-layer pavement system formed by laying a polymer adhesive and spreading colored wear-resistant aggregate on the road surface, serving both safety warning and aesthetic functions. Generally, MMA (methyl methacrylate) resin is used as the binder, and ceramic particles or quartz sand are used as aggregate. The aggregate particles increase the pavement's structural depth, facilitate rapid drainage in rainy weather, and increase tire contact point friction, resulting in a significantly higher coefficient of friction than traditional pavements. The construction method for colored anti-skid pavement involves cleaning the roadbed, first laying MMA resin on the pavement, then spreading aggregate particles, and finally sweeping away and recycling excess aggregate particles after the MMA resin has cured. Because not only excess aggregate but also aggregate that is not firmly bonded to the MMA resin needs to be recycled, vacuum cleaners cannot be directly used in this field, as they are ineffective at removing loosely bonded aggregate and may become clogged with resin residue. Therefore, currently, aggregate particle recycling is mostly carried out by construction workers using brooms and dustpans. This manual cleaning and recycling method is labor-intensive, requires a lot of manpower and time, and has low cleaning efficiency, making it difficult to quickly complete large-scale recycling operations, thus affecting the overall construction progress.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic anti-slip aggregate recycling device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic anti-slip aggregate recycling device, including a vehicle body, and further comprising:

[0006] A rotating rod is rotatably connected to the side wall of the vehicle body, and a pressure roller is rotatably connected to the rotating rod. The pressure roller is used to press the road surface.

[0007] A threaded rod, mounted on the vehicle body via a threaded seat, is used to adjust the relative position of the pressure roller and the road surface, as well as the pressure of the pressure roller on the road surface, by rotating the threaded rod against the rotating rod.

[0008] The main sweeping wheel is rotatably mounted on the vehicle body and is used to sweep the aggregate on the road surface in one pass.

[0009] The first drive motor is mounted on the vehicle body and is connected to the main sweeping wheel for driving the main sweeping wheel to rotate.

[0010] The auxiliary sweeping wheel is mounted on the vehicle body and is used for secondary sweeping of aggregate on the road surface;

[0011] The second drive motor is mounted on the vehicle body and is connected to the auxiliary sweeping wheel for driving the auxiliary sweeping wheel to rotate.

[0012] The first collection bucket is located at the bottom of the vehicle body and is used to collect the aggregate swept by the main sweeping wheel;

[0013] The second collection bucket is located at the bottom of the vehicle body and is used to collect the aggregate swept by the auxiliary sweeping wheel.

[0014] When using the automatic anti-slip aggregate recycling device of this invention for aggregate recycling, the device is first moved to the section of road that needs to be cleaned. By adjusting the threaded rod, the end of the threaded rod squeezes the rotating rod, causing it to rotate, thereby adjusting the relative position of the pressure roller and the road surface, so that the pressure roller contacts the ground and applies appropriate pressure. During the movement of the device, the pressure roller compresses the road surface, causing aggregates that are not firmly bonded to the resin to shift due to the pressure, and thus separate from the cured resin. Simultaneously, the first drive motor drives the main sweeping wheel to rotate, sweeping the aggregates that are not bonded to the resin on the road surface and sweeping these aggregates into the first collection hopper. Subsequently, the second drive motor drives the auxiliary sweeping wheel to rotate, performing a secondary sweeping of the aggregates that have separated from the resin after being compressed by the pressure roller, and sweeping these aggregates into the second collection hopper. The main sweeping wheel is mainly responsible for recycling easily cleaned aggregates, while the auxiliary sweeping wheel is responsible for recycling aggregates that are more difficult to clean after being processed by the pressure roller. This graded cleaning and collection method can effectively improve the aggregate recycling rate. The cooperation between the threaded rod and the rotating rod allows the pressure roller to bear part of the vehicle's weight, acting as a support and thus increasing the pressure on the road surface. The first and second drive motors drive the main and auxiliary sweeping wheels respectively, ensuring both power and efficiency in sweeping. The first and second collection buckets collect aggregates from different stages of sweeping, facilitating subsequent processing and utilization. The entire process automates aggregate recycling, significantly improving operational efficiency and reducing labor costs and intensity.

[0015] Furthermore, the automatic anti-slip aggregate recycling device also includes two collection shells, which are respectively inserted into the first collection hopper and the second collection hopper.

[0016] Preferably, the vehicle body is provided with a counterweight compartment for injecting counterweights to adjust the vehicle body's counterweight.

[0017] More specifically, the vehicle body has two drive wheels at the bottom, and each of these two drive wheels is driven by a servo motor.

[0018] Furthermore, the main sweeping wheel is connected to the first drive motor via a belt.

[0019] Furthermore, the auxiliary sweeping wheel is connected to the second drive motor via a belt.

[0020] Preferably, a first shovel plate is provided on the side wall of the first collection hopper, and the first shovel plate is located behind the main sweeping wheel; a second shovel plate is provided on the side wall of the second collection hopper, and the second shovel plate is located behind the auxiliary sweeping wheel.

[0021] Furthermore, the pressure roller is located between the main sweeping wheel and the auxiliary sweeping wheel.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The main sweeping wheel and auxiliary sweeping wheel are driven by a first drive motor and a second drive motor, respectively. They sweep away unadhesive aggregate and aggregate separated by pressure rollers on the road surface, collecting the aggregate into a first collection hopper and a second collection hopper, and finally transferring it to a collection shell for storage. This technical solution solves the problems of high labor intensity and low efficiency in manual aggregate recycling in existing technologies, achieving automation or semi-automation of aggregate recycling, significantly reducing the labor intensity of construction workers and improving the efficiency of aggregate recycling operations. Furthermore, by effectively recycling loosely adhered aggregate, the aggregate recycling rate is increased, avoiding waste of production materials, and resulting in good economic and social benefits.

Detailed Implementation

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] During the construction of colored anti-skid pavement, colored wear-resistant aggregate needs to be spread on the road surface, and after the adhesive has cured, excess and poorly adhered aggregate needs to be swept and recycled. Traditional recycling methods mostly involve manual sweeping with brooms and dustpans, which is labor-intensive, inefficient, and difficult to meet the needs of rapid construction. To solve this technical problem, this utility model provides an automatic anti-skid aggregate recycling device. This device applies pressure to the road surface with pressure rollers to loosen poorly adhered aggregate, and uses main and auxiliary sweeping wheels for graded sweeping and collection, thereby achieving automated aggregate recycling, significantly improving recycling efficiency and reducing labor intensity.

[0031] This utility model discloses an automatic anti-skid aggregate recycling device, which is mainly used for recycling aggregates on the road surface after the construction of colored anti-skid pavement. The device includes a vehicle body 1, which serves as the main frame of the entire device and supports other components. The vehicle body 1 is equipped with a pressure roller 5 for pressing the road surface, a main sweeping wheel 9 and a secondary sweeping wheel 10 for sweeping the aggregates, and a first collection hopper 11 and a second collection hopper 12 for collecting the aggregates.

[0032] like Figures 1 to 4 The automatic anti-slip aggregate recycling device shown includes a vehicle body 1, and further includes:

[0033] Rotary rod 4 is rotatably connected to the side wall of vehicle body 1. Pressure roller 5 is rotatably connected to rotary rod 4. Pressure roller 5 is used to press the road surface.

[0034] The threaded rod 3 is mounted on the vehicle body 1 via a threaded seat. It is used to adjust the relative position of the pressure roller 5 and the road surface, as well as the pressure of the pressure roller 5 on the road surface, by rotating the threaded rod 3 to abut against the rotating rod 4.

[0035] The main sweeping wheel 9 is rotatably mounted on the vehicle body 1 and is used to sweep the aggregate on the road surface in one pass.

[0036] The first drive motor 7 is mounted on the vehicle body 1 and is connected to the main sweeping wheel 9 for driving the main sweeping wheel 9 to rotate.

[0037] A secondary sweeping wheel 10 is mounted on the vehicle body 1 and is used for secondary sweeping of aggregates on the road surface;

[0038] The second drive motor 8 is mounted on the vehicle body 1 and is connected to the auxiliary sweeping wheel 10 for driving the auxiliary sweeping wheel 10 to rotate.

[0039] The first collection bucket 11 is located at the bottom of the vehicle body 1 and is used to collect the aggregate swept by the main sweeping wheel 9;

[0040] The second collection bucket 12 is located at the bottom of the vehicle body 1 and is used to collect the aggregate swept by the auxiliary sweeping wheel 10.

[0041] In practical implementation, when using the automatic anti-slip aggregate recycling device of this utility model for aggregate recycling operations, the device is first moved to the section of road that needs to be cleaned. By adjusting the threaded rod 3, the end of the threaded rod 3 squeezes the rotating rod 4, causing the rotating rod 4 to rotate, thereby adjusting the relative position of the pressure roller 5 and the road surface, so that the pressure roller 5 abuts against the ground and applies appropriate pressure. During the movement of the device, the pressure roller 5 presses against the road surface, causing the aggregate that is not firmly bonded to the resin to shift due to the pressure, and thus separate from the cured resin. At the same time, the first drive motor 7 drives the main sweeping wheel 9 to rotate, sweeping the aggregate on the road surface that is not bonded to the resin and sweeping these aggregates into the first collection hopper 11. Subsequently, the second drive motor 8 drives the auxiliary sweeping wheel 10 to rotate, performing a second sweeping of the aggregate that has separated from the resin after being pressed by the pressure roller 5, and sweeping these aggregates into the second collection hopper 12. The main sweeping wheel 9 is primarily responsible for recovering easily swept aggregates, while the auxiliary sweeping wheel 10 is responsible for recovering aggregates that are more difficult to sweep after being processed by the pressure roller 5. This tiered sweeping and collection method effectively improves the aggregate recovery rate. The cooperation between the threaded rod 3 and the rotating rod 4 allows the pressure roller 5 to bear part of the weight of the vehicle body 1, acting as a support and thus increasing the pressure on the road surface. The first drive motor 7 and the second drive motor 8 drive the main sweeping wheel 9 and the auxiliary sweeping wheel 10 respectively, ensuring sweeping power and efficiency. The first collection bucket 11 and the second collection bucket 12 collect aggregates swept at different stages, facilitating subsequent processing and utilization. The entire process automates aggregate recovery, significantly improving operational efficiency and reducing labor costs and intensity.

[0042] As one embodiment of the present invention, it also includes two collection shells 13, which are respectively inserted into the first collection hopper 11 and the second collection hopper 12.

[0043] In practice, the collection shell 13 can be understood as a movable container or inner liner, whose shape and size match the internal space of the first collection hopper 11 and the second collection hopper 12 to allow for easy insertion and removal. For example, the collection shell 13 can be made of a lightweight and wear-resistant material, such as plastic or a thin metal plate. After the cleaning operation is completed, the aggregate collected in the first collection hopper 11 and the second collection hopper 12 is actually contained within the collection shell 13 inserted therein. At this point, there is no need to empty the entire device or collection hoppers; simply remove the collection shell 13 filled with aggregate from the corresponding collection hopper.

[0044] By incorporating a pluggable collection shell 13, this utility model's anti-slip automatic aggregate recycling device can more conveniently and quickly transfer aggregates out of the device after collection. This greatly simplifies the aggregate transfer and storage process, reduces the complexity and labor intensity of manual operation, and improves the efficiency and cleanliness of subsequent processing. Compared with directly pouring aggregates from a fixed collection hopper, using the collection shell 13 avoids the possibility of aggregate spillage, making the recycling operation cleaner and more efficient, further enhancing the device's practicality and user experience.

[0045] As one embodiment of this utility model, the vehicle body 1 is provided with a counterweight compartment 2, which is used to inject counterweights to adjust the counterweight of the vehicle body 1.

[0046] In practice, the main function of the counterweight bin 2 is to adjust the weight at the front of the vehicle body 1. Since the pressure roller 5 is usually located at the front or bottom of the vehicle body 1, increasing the counterweight at the front of the vehicle body 1 can directly or indirectly increase the downward pressure applied to the pressure roller 5. For example, when recycling more firmly bonded aggregate, more counterweight can be injected into the counterweight bin 2, thereby increasing the pressure of the pressure roller 5 on the road surface and helping to loosen the aggregate. Conversely, when processing less bonded aggregate, the amount of counterweight can be reduced.

[0047] As one embodiment of this utility model, the bottom of the vehicle body 1 is provided with two drive wheels 16, which are driven by two servo motors 14 respectively.

[0048] In practice, by using independent servo motors 14 to drive the two drive wheels 16 respectively, independent and precise control of the rotational speed of each drive wheel 16 can be achieved. When the two servo motors 14 run synchronously at the same speed, the two drive wheels 16 rotate at the same speed, and the device will move in a straight line. When it is necessary to change the direction of movement of the device, such as when working on a curved road surface, the two servo motors 14 can be controlled to rotate at different speeds. For example, slowing down the rotational speed of the inner drive wheel 16 or speeding up the rotational speed of the outer drive wheel 16 can achieve steering of the device. This differential drive method gives the device flexible steering capabilities.

[0049] In one embodiment of this utility model, the main sweeping wheel 9 is connected to the first drive motor 7 via a belt.

[0050] In one embodiment of this utility model, the auxiliary sweeping wheel 10 is connected to the second drive motor 8 via a belt.

[0051] As one embodiment of the present invention, a first shovel plate 6 is provided on the side wall of the first collection bucket 11, and the first shovel plate 6 is located behind the main sweeping wheel 9. A second shovel plate 15 is provided on the side wall of the second collection bucket 12, and the second shovel plate 15 is located behind the auxiliary sweeping wheel 10.

[0052] In practical implementation, the first shovel plate 6 and the second shovel plate 15 can be understood as an inclined or curved plate-like structure, which functions similarly to a guide plate or baffle. For example, when the main sweeping wheel 9 rotates at high speed and sweeps up aggregates on the road surface, these aggregates will move along a certain trajectory. By setting the first shovel plate 6 behind the main sweeping wheel 9, and usually positioning its bottom close to the ground or maintaining a certain gap with the ground, the shovel plate can effectively intercept and guide the aggregates swept up by the main sweeping wheel 9, causing their movement direction to deviate towards the inlet of the first collection hopper 11, thereby ensuring that the aggregates can fall smoothly into the collection hopper and reducing the situation where aggregates splash or scatter outside the collection range; the guiding principle of the second shovel plate 15 is the same as that of the first shovel plate 6.

[0053] In one embodiment of this utility model, the pressure roller 5 is located between the main cleaning wheel 9 and the auxiliary cleaning wheel 10.

[0054] In practice, this specific arrangement is based on an optimized sweeping and recycling process design. The main sweeping wheel 9, as the first sweeping mechanism, is primarily responsible for sweeping up most of the aggregate that is not bonded to the resin on the road surface. The pressure roller 5, which follows closely behind, applies pressure to the road surface after the initial sweeping by the main sweeping wheel 9. At this point, some aggregate that is not firmly bonded to the resin may still remain on the road surface; the pressure of the pressure roller 5 effectively loosens or separates this aggregate from the resin. Finally, the auxiliary sweeping wheel 10, located behind the pressure roller 5, performs a secondary sweeping of the area that has undergone pressure treatment, specifically collecting the aggregate that has been loosened or separated by the pressure roller 5.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
