TECHNICAL FIELD
[0001] The present application relates to the technical field of highway maintenance pit groove processing, in particular to a bituminous highway maintenance pit groove processing device. BACKGROUND
[0002] Bituminous highway pit groove is one of common problems of pavement, which is mainly caused by vehicle load, temperature change, rain erosion and other factors to cause damage to bituminous layer. If the pit groove is not treated in time, it will accelerate the deterioration of the pavement and affect the driving safety and comfort.
[0003] Generally, the construction worker first determines the depth, area and surrounding damage (such as cracks, loose, etc.) of the pit groove. Then a regular rectangle or circle is cut along the edge of the pit groove by a cutting machine, and the edge is perpendicular to the pavement to avoid jaggedness. If the base layer is damaged, it needs to be excavated to the hard part and repaired to the design elevation with C15 concrete or cement stabilized macadam. When the base layer is not damaged, it is directly cleaned to a clean and solid surface. Preferably, the same gradation and bitumen type as the original pavement are selected. Finally, the wheel track is eliminated by repeatedly rolling with a steel wheel roller.
[0004] When the prior art maintains the bituminous pavement, for the emergency repair of large deep pit groove (area > 1 m2, depth > 5 cm), the large gravel is first scooped out with a shovel, and then the small particles are swept with a broom, and the small particles are swept in a pile. The pit groove is excavated with a shovel, which is time-consuming and labor-intensive. In addition, when there is water accumulation in the pit groove, the small particles of sand and gravel are mixed with the water accumulation, and it is more labor-intensive to swing the broom, and the small bituminous particles cannot be completely cleaned out of the deep pit groove, and the cleaning effect is not ideal.

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0020] In the embodiments, the present application provides an asphalt highway maintenance pit groove processing device, as shown in Figure 1 and Figure 6 , which comprises a cleaning piece, the cleaning piece comprising a cover 1 and a plurality of cleaning brushes arranged below the cover 1; the cleaning brush has a bushing 210 and a plurality of cleaning pieces 21 installed along the radial outer wall of the bushing 210; the cleaning piece 21 is made of silica gel piece, which is suitable for wet or sticky sand, and can wrap the particles by elastic deformation and throw them out. It can also be made of wear-resistant materials such as nylon, steel wire or carbon fiber to enhance the scraping and throwing ability of the sand. The bushings 210 of the plurality of cleaning brushes are inserted with a main shaft 2, the radial side wall of the main shaft 2 is provided with a notch, and the inner wall of the bushing 210 is provided with a protruding part one for slidingly connecting with the notch; a threaded groove is formed in the bottom wall of the end of the notch away from the hollow connecting seat 23, and a limit pin 29 is threadedly inserted into the threaded groove to block the protruding part one from sliding out of the notch. In this way, the assembly between the plurality of cleaning brushes and the main shaft 2 is completed. The significance of the above design is that when some cleaning brushes are severely worn, the limit pin 29 can be rotated in reverse to disengage from the threaded groove, the plurality of bushings 210 can be pulled out of the main shaft 2, and after replacing the new cleaning brush, the bushing 210 can be sleeved on the main shaft 2 and locked by the limit pin 29, thereby reducing the additional cost of replacing the cleaning brush.
[0021] At the same time, the outer wall of one end of the main shaft 2 is rotatably sleeved with a hollow connecting seat 23, the hollow connecting seat 23 is fixed with a hollow tube 22 penetrating through the edge side of one end of the cover 1, and the end of the hollow tube 22 extending out of the cover 1 is fixedly connected with a hollow operating rod 3. The hollow operating rod 3 is in communication with the hollow tube 22, and a transmission rod for providing forward and reverse rotation of the main shaft 2 is built-in, thereby driving the plurality of cleaning brushes to rotate forward and reverse, and changing the direction of the residual sand in the pit groove.
[0022] Specifically, asFigure 3 As shown, the transmission rod comprises a rod one 25 rotationally arranged in the hollow operating rod 3 and a rod two 24 rotationally arranged in the hollow tube 22, and the two ends of the rod one 25 and the rod two 24 close to each other are both welded with a connecting ring 26, and the two connecting rings 26 are sleeved together at the intersection of the hollow operating rod 3 and the hollow tube 22. Figure 4 As shown, a bevel gear one 28 is fixedly sleeved on the outer wall of the main shaft 2 and located in the hollow connecting seat 23, the end of the rod two 24 extends into the hollow connecting seat 23 and is fixedly connected with a bevel gear two 27 engaged with the bevel gear one 28. Figure 1 and Figure 2 As shown, the power member 4 comprises a shell in which a lithium battery is embedded and a servo motor embedded in the shell, the shell is provided with a hollow threaded head threadedly connected with an internal thread, the output end of the servo motor is connected with a rectangular rod rotationally extending out of the hollow threaded head, the end of the hollow operating rod 3 is provided with an internal thread threadedly connected with the hollow threaded head, and the end of the rod one 25 is provided with a rectangular slot tightly inserted with the rectangular rod.
[0023] The lithium battery supplies power for the servo motor, and the shell is further provided with a control switch for controlling the forward and reverse rotation of the servo motor. When the servo motor rotates, the rectangular rod, the rod one 25 and the rod two 24 serve as transmission media to provide a power source for the bevel gear two 27, which in turn drives the bevel gear one 28 and the main shaft 2 to rotate synchronously, thereby driving the cleaning brush to rotate. Here, two universal wheels 11 are rotationally arranged at the two side positions of the same side of the cover 1, and the height of the bottom wall where the cleaning sheet 21 is located is higher than the height of the bottom wall where the wheel body of the universal wheel 11 is located. The two universal wheels 11 serve as fulcrums for the lifting and falling of the cleaning sheet 21. The worker holds the hollow operating rod 3, and presses the hollow operating rod 3 downward with the two universal wheels 11 as the fulcrums, so as to lift the cleaning member upward and separate it from the ground. The worker can push the equipment forward to move forward by using the universal wheels 11. During cleaning, the pushing is stopped, and the hollow operating rod 3 is lifted upward with the two universal wheels 11 as the fulcrums, so as to make the cleaning member fall and press on the bottom wall in the pit. The power member 4 is started to provide rotating power for the rotation of the cleaning sheet 21, thereby achieving the purpose of automatically cleaning the sand and gravel in the pit.
[0024] Here, the cover 1 is of a circular arc structure, and the cleaning sheet 21 does not touch the inner top wall of the cover 1, which does not affect the rotation of the cleaning sheet 21. Further, the cleaning sheet 21 is divided into three parts. Figure 8As shown, the first part 213, the second part 212 and the third part 211 are sequentially distributed from close to the sleeve 210 to far from the sleeve 210 and are continuously connected together. The hardness of the first part 213, the second part 212 and the third part 211 gradually becomes soft, the third part 211 is bendable, and the second part 212 serves as an intermediate medium connecting the first part 213 and the third part 211. The hardness of the end of the second part 212 connecting with the third part 211 is greater than the hardness of the third part 211 itself, and the hardness of the end of the second part 212 connecting with the first part 213 is less than the hardness of the first part 213 itself. That is, the second part 212 will not be completely bent, ensuring that the end of the cleaning sheet 21 is partially bent during cleaning, so as to avoid the cleaning sheet 21 not having enough hardness to meet the throwing of gravel.
[0025] In this way, the cleaning sheet 21 can be contacted with the inner bottom wall of the pit by pressing the entire device, and the third part 211 is appropriately bent, so as to increase the contact surface with the gravel in the pit, and the cleaning sheet 21 has friction, and the gravel can be thrown out as the cleaning sheet 21 continuously rotates. Moreover, it can be seen from Figure 8 that the third part 211 is bent and extended, and the angle between the third part 211 and the second part 212 is 15°-30°. The oblique force generated during rotation helps to throw the gravel out of the pit.
[0026] The deformation gap is provided between the adjacent two cleaning sheets 21 on the same sleeve 210, and the deformation gap provides space for the cleaning sheet 21 contacting the ground to be bent and deformed.
[0027] When cleaning a deeper pit, the cleaning sheet 21 sweeps to the corner position in the pit. Since the pit has a depth, the longitudinal side wall in the pit will block the gravel thrown by the cleaning sheet 21, and the gravel hitting the longitudinal side wall in the pit will rebound to the bottom wall in the pit. The worker can shovel out the pit by means of a shovel after the gravel is swept to a pile again by means of the broom.
[0028] Therefore, the recycling drawer 51 is also disclosed in the embodiment, and the sidewall of the recycling drawer 51 facing the cleaning sheet 21 is provided with an inlet. Specifically, as shown in Figure 1 、 Figure 5 and Figure 9As shown, the top wall side of the recovery drawer 51 is fixed with an inverted L-shaped hanging rod, the other end of the inverted L-shaped hanging rod is fixed with a sliding sleeve 5, the sliding sleeve 5 is sleeved on the outer wall of the hollow pipe 22, the inner wall of the sliding sleeve 5 is provided with a protruding part two, the outer wall of the hollow pipe 22 is provided with a sliding groove which is slidably connected with the protruding part two, meanwhile, the top wall of the sliding sleeve 5 is provided with a pull ring, the pull ring is connected with a pull rope 53, the other end of the pull rope 53 is connected with a buckle ring, the outer wall of the hollow operating rod 3 is provided with two limiting columns 31 which can hook the buckle ring. Here, the distance between the two limiting columns 31 is equal to the length of the sliding groove, so the adjusting stroke of the sliding sleeve 5 on the hollow pipe 22 is the distance between the two limiting columns 31.
[0029] As shown in the drawings, Figure 1 When the cleaning sheet 21 reversely rotates, the sand will be thrown by the cleaning sheet 21 to the direction of the feed inlet of the recovery drawer 51. At this time, the buckle ring is removed from the higher limiting column 31 of the hollow operating rod 3, the sliding sleeve 5 slides downward along the outer wall of the hollow pipe 22 under the action of gravity, here the hollow pipe 22 is arranged upwardly inclined, at this time, the recovery drawer 51 is lowered along the distribution direction of the inclined hollow pipe 22 through the linkage of the inverted L-shaped hanging rod, so that the height of the feed inlet of the recovery drawer 51 gradually decreases, until the height of the feed inlet can receive the sand thrown by the cleaning sheet 21. Moreover, in order to avoid the sand being thrown out from the bottom wall of the recovery drawer 51, the bottom wall of the feed inlet opening is provided with a rubber extension piece 52 which is inclined downward, the rubber extension piece 52 has the characteristics of bending deformation, so when the recovery drawer 51 is adjusted downward, the bottom wall of the recovery drawer 51 does not need to touch the ground, only the end of the rubber extension piece 52 needs to touch the ground, so as to ensure that the sand can fly into the feed inlet along the inclined rubber extension piece 52 during the throwing process, and the sand can be collected to the maximum extent.
[0030] It should be noted that during the sliding process, the protruding part two slides synchronously along the sliding groove, so as to avoid the rotation of the sliding sleeve 5 on the outer wall of the hollow pipe 22, and to avoid the inclination of the inlet, which affects the collection of the sand.
[0031] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
