Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a road grooving machine for municipal construction. Background Technology

[0002] After prolonged use, road surfaces may develop structural cracks due to traffic loads and temperature cracks due to temperature changes in the asphalt surface layer. In such cases, a road grooving machine is needed to groove the cracks, making it easier for subsequent cleaning and filling and repair with road sealant.

[0003] When existing road grooving machines are in operation, workers usually need to pull them to the work site, and then drive the grooving cutter to rotate through the drive device, and work together with the workers to pull the road grooving machine to move it, so as to grooving the ground through the rotation and movement of the grooving cutter;

[0004] Existing road grooving machines have the following problems: after a period of use, the grooving blades may be partially damaged or severely worn, requiring the entire grooving blade to be replaced, which wastes resources. To address this, we propose a new road grooving machine for municipal construction. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a municipal construction road grooving machine. The grooving blade is installed on the mounting plate through a quick-release mechanism. When some grooving blades are damaged or severely worn, only the corresponding grooving blade needs to be removed and replaced, without having to replace all of them, thus saving resources and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal construction road grooving machine, including a grooving frame, an adjustable mounting plate inside the grooving frame, and a quick-release mechanism;

The outer surface of the mounting plate has evenly distributed mounting slots. Fixing seats are inserted into the interior of each mounting slot through the limiting components. Grooving blades are evenly distributed on the side of the fixing seats away from the center of the mounting plate. Insertion ports are opened on the left side of each fixing seat. Grooves are opened on the left wall of each mounting slot. Sliding pillars are slidably connected inside each groove. Insertion blocks are provided at the right end of each sliding pillar. Insertion blocks are inserted into the interior of adjacent insertion ports. The grooving blades are installed on the mounting plate through the quick-release mechanism. When some grooving blades are damaged or severely worn, only the corresponding grooving blades need to be removed and replaced, without replacing all of them, thus saving resources.

[0008] Furthermore, the limiting component includes rib grooves and ribs. Rib grooves are provided on both the left and right walls of the mounting groove, and ribs are provided on both the left and right sides of the fixing seat. The ribs are slidably connected to the interior of the adjacent rib grooves to facilitate limiting the fixing seat.

[0009] Furthermore, the quick-release mechanism also includes springs and pull blocks. Springs are movably sleeved on the outer surface of the slide column. The springs are located between the left side of the adjacent insert and the left wall of the slot. Pull blocks are provided at the left end of the slide column to facilitate fixing the mounting plate and the grooving knife together.

[0010] Furthermore, it also includes a microcontroller, which is fixedly connected to the left side of the grooving frame. A battery is provided on the upper surface of the grooving frame, and the input terminal of the microcontroller is electrically connected to the output terminal of the battery to facilitate the normal operation of the equipment.

[0011] Furthermore, the left and right walls of the grooving frame are provided with sliding grooves, and a support frame is slidably connected between the two sliding grooves. An electric push rod is provided in the mounting hole on the upper surface of the grooving frame. The lower end of the telescopic shaft of the electric push rod is fixedly connected to the upper surface of the support frame. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the adjustment of the height of the grooving cutter.

[0012] Furthermore, the support frame is internally connected to a mounting plate via a rotating shaft. A motor is located on the right side of the support frame. The left end of the motor's output shaft is fixedly connected to the right end of the rotating shaft. The input end of the motor is electrically connected to the output end of the microcontroller, which facilitates driving the grooving cutter to rotate.

[0013] Furthermore, it also includes a dust removal mechanism, which includes a dust collection box, a fan, a filter, a suction pipe, and a suction nozzle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This municipal construction road grooving machine has the following advantages:

[0015] When some grooving cutters are damaged or severely worn, pull the corresponding pull block to move the insert block via the sliding column until the insert block leaves the socket, releasing the fixing relationship between the mounting plate and the fixing seat. Then, the corresponding grooving cutter along with the fixing seat can be pulled out of the mounting slot. Insert the replacement grooving cutter into the mounting slot through the fixing seat. The spring pushes the insert block into the socket through the rebound force, thus completing the replacement of the grooving cutter.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This embodiment provides a technical solution: a municipal construction road grooving machine, including a grooving frame 1, an adjustable mounting plate 5 inside the grooving frame 1, a quick-release mechanism 3, and a microcontroller 2. The microcontroller 2 is fixedly connected to the left side of the grooving frame 1. A battery 4 is provided on the upper surface of the grooving frame 1, and the input end of the microcontroller 2 is electrically connected to the output end of the battery 4. Slide grooves 11 are provided on both the left and right walls of the grooving frame 1, and a support frame 7 is slidably connected between the two slide grooves 11. An electric push rod 6 is provided in the mounting hole on the upper surface of the grooving frame 1, and the lower end of the telescopic shaft of the electric push rod 6 is fixedly connected to the upper surface of the support frame 7. The input end of rod 6 is electrically connected to the output end of microcontroller 2. The support frame 7 has a mounting plate 5 rotatably connected inside via a rotating shaft 9. A motor 10 is located on the right side of the support frame 7. The left end of the output shaft of motor 10 is fixedly connected to the right end of rotating shaft 9. The input end of motor 10 is electrically connected to the output end of microcontroller 2. It also includes a dust removal mechanism 8, which includes a dust collection box 81, a fan 82, a filter screen 83, a suction pipe 84, and a suction nozzle 85. (A hinged door is located on the left side of the dust collection box 81. A sealing strip is provided on the right side of the door to ensure its sealing when closed. The right side of the door contacts the left side of the filter screen 83 when closed.) A door lock is provided at the junction of the dust box 81 (the door lock is a common type of door lock used in the prior art). The dust collection box 81 is located on the upper surface of the grooving frame 1. A fan 82 is installed in the mounting port on the rear side of the dust collection box 81. A filter screen 83 is installed inside the dust collection box 81. A suction pipe 84 is installed at the opening on the front side of the dust collection box 81. A suction nozzle 85 is installed at the air inlet of the suction pipe 84. The input end of the fan 82 is electrically connected to the output end of the microcontroller 2. After the operator moves the road grooving machine to the work area through the grooving frame 1, he controls the microcontroller 2 to open the electric push rod 6. The telescopic shaft of the electric push rod 6 drives the support frame 7 to move downward along the slide 11. The installation plate 5 moves the grooving blade 33 downward until it is adjusted to a suitable height. Then, the motor 10 is turned on, and the output shaft of the motor 10 drives the installation plate 5 to rotate through the rotating shaft 9, so that the grooving blade 33 rotates around the rotating shaft 9. Then, the workers pull the road grooving machine through the grooving frame 1 to move it. The road surface is grooved by the rotation and movement of the grooving blade 33. At the same time, the blower 82 is turned on. The air 82 sucks the dust generated during the grooving process into the dust collection box 81 through the dust suction pipe 84 and the suction nozzle 85. The airflow passes through the filter screen 83 and is discharged from the dust collection box 81. The dust is blocked by the filter screen 83 and remains in the dust collection box 81.

[0024] Quick-release mechanism 3 includes mounting grooves 31, fixing seats 32, grooving blades 33, insertion ports 34, sliding pillars 35, insertion blocks 36, and limiting components 39. The outer surface of the mounting plate 5 has evenly distributed mounting grooves 31. Fixing seats 32 are inserted into the interior of each mounting groove 31 via the limiting components 39. Grooving blades 33 are evenly distributed on the side of each fixing seat 32 away from the center of the mounting plate 5. Insertion ports 34 are provided on the left side of each fixing seat 32. Grooves are provided on the left wall of each mounting groove 31, and sliding pillars 35 are slidably connected inside each groove. Each sliding column 35 has a plug 36 on its right end (the right end of the plug 36 is inclined on the side away from the center of the mounting plate 5). The plug 36 is inserted into the interior of the adjacent socket 34. The limiting component 39 includes a rib groove 391 and a rib 392. The left and right walls of the mounting groove 31 are provided with rib grooves 391. The left and right sides of the fixing seat 32 are provided with ribs 392. The ribs 392 are slidably connected to the interior of the adjacent rib grooves 391. The quick release mechanism 3 also includes a spring 37 and a pull block 38. The outer surface of the sliding column 35 is movably fitted with a spring. 37. Springs 37 are located between the left side of the adjacent insert 36 and the left wall of the slot. Each sliding post 35 has a pull block 38 at its left end. When some grooving cutters 33 are damaged or severely worn, the pull block 38 corresponding to the grooving cutter 33 is pulled. The pull block 38 drives the insert 36 to move through the sliding post 35 until the insert 36 leaves the slot 34 on the corresponding fixing seat 32. At this time, the insert 36 compresses the spring 37, releasing the fixing relationship between the mounting plate 5 and the fixing seat 32. Then, the corresponding grooving cutter 33 can be installed together with the fixing seat 32. The base 32 is pulled out from the mounting slot 31 together. Then, under the restriction of the rib groove 391 and rib 392, the replaced grooving knife 33 can be inserted into the mounting slot 31 through the fixing base 32. Since the right end of the insert block 36 is inclined away from the center of the mounting plate 5, the fixing base 32 presses the insert block 36 to the left during the insertion process until the insert block 36 corresponds to the socket 34. The spring 37 pushes the insert block 36 into the socket 34 through the rebound force, fixing the mounting plate 5 and the fixing base 32 together, thus completing the replacement of the grooving knife 33.

[0025] The working principle of the municipal construction road grooving machine provided by this utility model is as follows: After the worker moves the road grooving machine to the work area through the grooving machine frame 1, the single-chip microcomputer 2 is operated to open the electric push rod 6. The telescopic shaft of the electric push rod 6 drives the support frame 7 to move downward along the slide 11, causing the mounting plate 5 to drive the grooving blade 33 to move downward until the grooving blade 33 is adjusted to a suitable height. Then, the motor 10 is turned on. The output shaft of the motor 10 drives the mounting plate 5 to rotate through the rotating shaft 9, so that the grooving blade 33 rotates around the rotating shaft 9. Then, the worker pulls the road grooving machine to move through the grooving machine frame 1. The road surface is grooved by the rotation and movement of the grooving blade 33. At the same time, the fan 82 is turned on. The air 82 sucks the dust generated during the grooving process into the dust collection box 81 through the dust suction pipe 84 and the suction nozzle 85. The airflow passes through the filter screen 83 and is discharged from the dust collection box 81. The dust is blocked by the filter screen 83 and remains in the dust collection box 81. When some of the grooving cutters 33 are damaged or severely worn, pull the pull block 38 corresponding to the grooving cutter 33. The pull block 38 drives the insert block 36 to move through the slide column 35 until the insert block 36 leaves the socket 34 on the corresponding fixing seat 32. At this time, the insert block 36 compresses the spring 37, releasing the fixing relationship between the mounting plate 5 and the fixing seat 32. Then, the corresponding grooving cutter 33, together with the fixing seat 32, can be pulled out from the mounting groove 31. After that, under the restriction of the rib groove 391 and the rib 392, the replaced grooving cutter 33 can be inserted into the mounting groove 31 through the fixing seat 32. Since the right end of the insert block 36 is inclined away from the center of the mounting plate 5, the fixing seat 32 squeezes the insert block 36 to the left during the insertion process until the insert block 36 corresponds to the socket 34. The spring 37 pushes the insert block 36 into the socket 34 through the rebound force, fixing the mounting plate 5 and the fixing seat 32 together, thus completing the replacement of the grooving cutter 33.

[0026] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STC89C52, the fan 82 can be an SF axial flow fan, and the motor 10 can be an MSMD012G1U. The microcontroller 2 controls the operation of the electric push rod 6, the fan 82 and the motor 10 using methods commonly used in the prior art.
