Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to a preventive maintenance device for road micro-surfacing. Background Technology

[0002] Road maintenance refers to the upkeep and maintenance of roads, including their structures and facilities, to maintain their usability as much as possible, promptly restore damaged parts, ensure safe, comfortable, and smooth traffic flow, save transportation costs and time, adopt correct technical measures, improve project quality, extend the service life of roads, and postpone reconstruction. Microsurfacing is a preventive maintenance method developed based on slurry seal. The raw materials are stone chips or sand with a certain gradation, fillers, etc. At present, microsurfacing preventive maintenance is a relatively important measure for road maintenance.

[0003] In existing technologies, when maintenance devices are used for preventive micro-surfacing of roads, the road maintenance agent tends to settle and solidify in the storage tank and adheres to the inner wall of the tank. It is difficult to scrape off the maintenance agent from the inner wall of the storage tank, requiring manual cleaning, which increases the workload of the staff and affects work efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a preventative maintenance device for road micro-surfacing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a road micro-surfacing preventive maintenance device, comprising a base, rollers disposed at the bottom of the base, a storage bin fixed to the upper surface of the base, and a discharge pipe fixed to and connected to the bottom of the storage bin. The discharge pipe passes through the base and is fixed to the base. A mounting frame is fixed to the upper surface of the base. A rotating shaft rotatably connected to the mounting frame is disposed through the mounting frame. A plurality of stirring rods fixedly sleeved on the rotating shaft are disposed inside the storage bin. A fixing rod is fixed to the end of each stirring rod. A scraper is fixed to the end of the fixing rod away from the stirring rod. The side wall of the scraper away from the fixing rod abuts against the inner wall of the storage bin. A drive assembly for driving the rotating shaft to rotate is mounted on the mounting frame.

[0006] By adopting the above technical solution, when performing preventive maintenance on road microsurfacing, the road maintenance agent is stored in a storage tank. The drive component drives the rotating shaft to rotate, thereby causing multiple stirring rods to stir the maintenance agent in the storage tank, reducing the probability of the maintenance agent settling and solidifying. While the stirring rods rotate, the scraper rotates around the rotating shaft with the stirring rods, thereby scraping off the maintenance agent on the inner wall of the storage tank, reducing the probability of the maintenance agent adhering to the inner wall of the storage tank.

[0007] Furthermore, the drive assembly includes a drive motor fixed to the upper surface of the mounting bracket, a drive gear fixed to the end of the output shaft of the drive motor, and a driven gear fixed to the upper end of the rotating shaft and meshing with the drive gear.

[0008] By adopting the above technical solution, the drive motor is started to drive the active gear to rotate. Since the active gear meshes with the driven gear and the driven gear is fixed to the upper end of the rotating shaft, the rotating shaft is rotated, thereby stirring the curing agent and scraping off the curing agent from the inner wall of the storage tank.

[0009] Furthermore, the side wall of the feeding pipe has an opening, and the base and the feeding pipe are jointly equipped with an adjustment component for adjusting the feeding amount. The adjustment component includes a mounting block that is fixed to the side wall of the base and the side wall of the feeding pipe. The side wall of the mounting block near the feeding pipe has a receiving groove that matches the opening of the feeding pipe. The adjustment component also includes an adjustment plate that is slidably connected to the inner wall of the receiving groove and a cylinder that is fixed to the side wall of the mounting block. The piston rod of the cylinder passes through the side wall of the mounting block and is fixed to the side wall of the adjustment plate.

[0010] By adopting the above technical solution, the size of the discharge pipe opening can be adjusted by adjusting the piston rod of the cylinder, thereby facilitating the adjustment of the flow rate of the curing agent discharged through the discharge pipe.

[0011] Furthermore, a vertical rod rotatably connected to the base is provided through the base, a cleaning brush is provided at the bottom of the vertical rod, and a linkage component for driving the vertical rod to rotate is jointly installed on the vertical rod and the drive motor.

[0012] By adopting the above technical solution, the vertical rod is driven to rotate through the linkage component, thereby causing the cleaning brush to rotate and clean the ground, reducing the probability of road dust and debris affecting road maintenance.

[0013] Furthermore, the linkage assembly includes a first pulley fixed to the upper end of the vertical rod, a second pulley fixedly sleeved on the output shaft of the drive motor, and a transmission belt sleeved on the first pulley and the second pulley.

[0014] By adopting the above technical solution, the rotating shaft is driven by the drive motor, and the vertical rod is driven to rotate simultaneously by the transmission belt, so that the cleaning brush can clean dust and debris from the ground.

[0015] Furthermore, the bottom wall of the storage hopper is inclined downwards on the side facing the feeding pipe.

[0016] By adopting the above technical solution, the curing agent on the bottom wall of the storage tank flows towards the feed pipe under the action of gravity, reducing the probability of curing agent depositing on the bottom wall of the storage tank.

[0017] Furthermore, the bottom of the base is provided with a flat plate and a pressing roller.

[0018] By adopting the above technical solution, the leveling plate and the pressing roller work together to level the curing agent laid on the road, which helps to improve the smoothness of the road after curing.

[0019] Furthermore, a handle is fixed to the upper surface of the base.

[0020] By adopting the above technical solution, the handle provides a fulcrum for the base, making it easier for staff to move the device by pushing it.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, when performing preventive maintenance on road micro-surfacing, the road maintenance agent is placed in a storage tank and stored. The drive component drives the rotating shaft to rotate, thereby causing multiple stirring rods to stir the maintenance agent in the storage tank, reducing the probability of the maintenance agent settling and solidifying. While the stirring rods rotate, the scraper rotates around the rotating shaft with the stirring rods, thereby scraping off the maintenance agent on the inner wall of the storage tank, reducing the probability of the maintenance agent adhering to the inner wall of the storage tank.

[0023] 2. In this application, the drive motor is started to drive the drive gear to rotate. Since the drive gear meshes with the driven gear and the driven gear is fixed to the upper end of the shaft, the shaft rotates, thereby stirring the curing agent and scraping off the curing agent on the inner wall of the storage tank.

[0024] 3. In this application, the piston rod of the cylinder is adjusted to move so that the size of the opening of the discharge pipe can be adjusted by the adjusting plate, which facilitates the adjustment of the flow rate of the curing agent discharged through the discharge pipe.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-3 As shown in the figure, this application discloses a road micro-surfacing preventive maintenance device, including a base 1, rollers 2, a storage bucket 3, a discharge pipe 4, a mounting frame 5, a rotating shaft 6, a mixing rod 7, a fixing rod 8, a scraper 9, and a drive assembly 10.

[0031] The base 1 is a cuboid structure used to support the device. Four rollers 2 are arranged in a rectangular array at the bottom of the base 1. The storage tank 3 is a cylindrical structure with an open top, fixed to the upper surface of the base 1. The discharge pipe 4 is a rectangular tubular structure, fixed and connected to the bottom of the storage tank 3, and passes through and is fixed to the base 1. The mounting frame 5 is a plate-like structure with an L-shaped cross-section, fixed to the upper surface of the base 1. The rotating shaft 6 is a vertically arranged cylindrical structure, passing through and rotatably connected to the mounting frame 5, with its axis coinciding with the axis of the storage tank 3. The stirring rod 7 is a horizontally arranged cylindrical structure, located inside the storage tank 3, and fixedly sleeved on the rotating shaft 6; multiple stirring rods 7 are provided. The fixing rod 8 is a horizontally arranged cylindrical structure, fixed to the end of the stirring rod 7. The scraper 9 is a rectangular plate structure. The scraper 9 is fixed to the end of the fixed rod 8 away from the stirring rod 7. The side wall of the scraper 9 away from the fixed rod 8 is pressed against the inner wall of the storage tank 3.

[0032] The drive assembly 10 is mounted on the mounting bracket 5 and is used to drive the rotating shaft 6 to rotate. The drive assembly 10 includes a drive motor 101, a driving gear 102, and a driven gear 103. The drive motor 101 is fixed to the upper surface of the mounting bracket 5, and the output shaft of the drive motor 101 extends vertically upward. The driving gear 102 is fixed to the end of the output shaft of the drive motor 101, and the axis of the driving gear 102 coincides with the axis of the output shaft of the drive motor 101. The driven gear 103 is fixed to the upper end of the rotating shaft 6, and the driven gear 103 meshes with the driving gear 102, and the axis of the driven gear 103 coincides with the axis of the rotating shaft 6.

[0033] When performing preventative maintenance on road microsurfacing, the road maintenance agent is stored in the storage tank 3. The drive motor 101 is started to drive the drive gear 102 to rotate. Since the drive gear 102 meshes with the driven gear 103, and the driven gear 103 is fixed to the upper end of the rotating shaft 6, the rotating shaft 6 rotates, thereby causing multiple stirring rods 7 to stir the maintenance agent in the storage tank 3, reducing the probability of the maintenance agent settling and solidifying. While the stirring rods 7 are rotating, the scraper 9 rotates around the rotating shaft 6 with the stirring rods 7, thereby scraping off the maintenance agent on the inner wall of the storage tank 3, reducing the probability of the maintenance agent adhering to the inner wall of the storage tank 3.

[0034] To facilitate adjustment of the curing agent flow rate discharged through the discharge pipe 4, an opening is provided on one side wall of the discharge pipe 4. An adjustment assembly 11 is installed on both the base 1 and the discharge pipe 4 to adjust the discharge amount. The adjustment assembly 11 includes a mounting block 111, an adjustment plate 112, and a cylinder 113. The mounting block 111 is a cuboid structure, fixed to the side wall of the base 1. One side wall of the mounting block 111 is fixed to the side wall of the discharge pipe 4. A receiving groove 1111 is provided on the side wall of the mounting block 111 closest to the discharge pipe 4, which mates with the opening of the discharge pipe 4. The adjustment plate 112 is a rectangular plate structure, slidably connected to the inner wall of the receiving groove 1111. The cylinder 113 is fixed to the side wall of the mounting block 111, and its piston rod passes through the side wall of the mounting block 111 and is fixed to the side wall of the adjustment plate 112. The piston rod of cylinder 113 is moved by adjusting the adjustment plate 112 to adjust the size of the opening of the discharge pipe 4, thereby facilitating the adjustment of the flow rate of the curing agent discharged through the discharge pipe 4.

[0035] To reduce the probability of road dust and debris affecting road maintenance, a vertical rod 12 is rotatably connected to the base 1. A cleaning brush 13 is installed at the bottom of the vertical rod 12. A linkage assembly 14 is installed on both the vertical rod 12 and the drive motor 101 to drive the vertical rod 12 to rotate. The linkage assembly 14 includes a first pulley 141, a second pulley 142, and a transmission belt 143. The first pulley 141 is fixed to the upper end of the vertical rod 12, and the axis of the first pulley 141 coincides with the axis of the vertical rod 12. The second pulley 142 is fixedly sleeved on the output shaft of the drive motor 101, and the axis of the second pulley 142 coincides with the axis of the drive motor 101. The transmission belt 143 is a commonly used transmission belt in the prior art and applicable to this embodiment. The transmission belt 143 is sleeved on the first pulley 141 and the second pulley 142. While the drive motor 101 drives the rotating shaft 6 to rotate, the transmission belt 143 drives the vertical rod 12 to rotate simultaneously, thereby causing the cleaning brush 13 to rotate and clean the ground, reducing the probability of road dust and debris affecting road maintenance.

[0036] To reduce the probability of curing agent depositing on the bottom wall of the storage tank 3, the bottom wall of the storage tank 3 is tilted downwards towards the side facing the discharge pipe 4, so that the curing agent on the bottom wall of the storage tank 3 flows towards the discharge pipe 4 under the action of gravity, thereby reducing the probability of curing agent depositing on the bottom wall of the storage tank 3.

[0037] In order to improve the smoothness of the road after maintenance, a leveling plate 15 and a flattening roller 16 are provided at the bottom of the base 1. The leveling plate 15 and the flattening roller 16 work together to level the maintenance agent laid on the road, thereby improving the smoothness of the road after maintenance.

[0038] To facilitate the movement of the device, a handle 17 is fixed to the upper surface of the base 1. The handle 17 provides a point of leverage for the base 1, making it easier for workers to move the device by pushing it through the handle 17.

[0039] The working principle of the road micro-surfacing preventive maintenance device in this embodiment is as follows: When performing preventive maintenance on road micro-surfacing, the road maintenance agent is placed in the storage tank 3 for storage. By starting the drive motor 101, the drive gear 102 is driven to rotate. Since the drive gear 102 meshes with the driven gear 103, and the driven gear 103 is fixed to the upper end of the rotating shaft 6, the rotating shaft 6 is rotated, thereby causing multiple stirring rods 7 to stir the maintenance agent in the storage tank 3, reducing the probability of the maintenance agent settling and solidifying. At the same time as the stirring rods 7 rotate, the scraper 9 rotates around the rotating shaft 6 with the stirring rods 7, thereby scraping off the maintenance agent on the inner wall of the storage tank 3, reducing the probability of the maintenance agent adhering to the inner wall of the storage tank 3.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
