A municipal road finishing machine

Abstract

This utility model discloses a municipal road smoothing machine, including a fixed base. Two sets of first threaded rings are embedded on the upper surface of the fixed base, and an adjustment mechanism is connected to the inner ring of each first threaded ring. A U-shaped scraper is connected to the bottom surface of the fixed base, and a set of equally spaced scraper needles are connected to the bottom surface of the fixed base. A groove is formed in the inner top wall of the fixed base, and a drive motor is installed inside the groove. This device first uses the scraper and scraper needles to not only level the paved concrete initially, but also to break up sand holes and air bubbles inside the concrete, thus making the concrete surface roughly flat.

This not only makes the concrete pavement smoother but also improves the paving quality of the concrete pavement.

Description

Technical Field

[0001] This utility model relates to the field of road smoothing technology, and in particular to a municipal road smoothing mechanical device. Background Technology

[0002] Smoothing municipal roads is a crucial part of urban infrastructure construction. Uneven road surfaces can lead to traffic inconvenience, accelerated vehicle wear, reduced riding experience, and even pose a threat to pedestrian safety. Therefore, using road smoothing machinery to smooth road surfaces has become an important task for urban management and maintenance.

[0003] Currently, most existing road smoothing machines use a scraper to smooth the newly paved concrete road surface before directly smoothing it. This smoothing method can result in sand holes and air bubbles in the smoothed surface, leading to certain quality problems. Therefore, we propose a municipal road smoothing machine to solve the above problems. Utility Model Content

[0006] A municipal road smoothing machine includes a fixed base. Two sets of first threaded rings are embedded in the upper surface of the fixed base. An adjustment mechanism is connected to the inner ring of each first threaded ring. A U-shaped scraper is connected to the bottom surface of the fixed base. A set of equally spaced scraper needles is connected to the bottom surface of the fixed base. A groove is formed in the inner top wall of the fixed base. A drive motor is installed inside the groove. A connecting rod is connected to the output end of the drive motor. A smoothing plate is connected to the bottom end of the connecting rod. Two push handles are connected to the right side of the fixed base.

[0007] In a further embodiment, each of the adjusting mechanisms includes a threaded screw, a rotating handle is connected to the top of each threaded screw, a caster wheel is provided below each threaded screw, a second threaded ring is embedded on the upper surface of each caster wheel, and the inner ring of each second threaded ring is connected to the outer surface of each threaded screw.

[0008] In a further embodiment, a control panel is installed on the right side of the fixing base, and a spirit level is installed on the upper surface of the fixing base.

[0009] In a further embodiment, the upper surface of the fixing base is provided with a placement groove, and a counterweight plate is placed inside the placement groove.

[0010] In a further embodiment, the bottom surface of the fixing base is provided with an annular groove, and an annular plate is slidably connected inside the annular groove. The bottom end of the annular plate is connected to the upper surface of the polishing plate.

[0011] In a further embodiment, a battery is mounted on the upper surface of the mounting base, and a toolbox is connected to the upper surface of the mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device first uses a scraper and a scraper to level the concrete after it has been laid, and also to remove sand holes and air bubbles inside the concrete. This makes the surface of the concrete roughly flat. Then, the drive motor drives the connecting rod and the trowel to rotate. The rotation of the trowel is used to smooth the surface of the concrete. This not only makes the concrete pavement smoother, but also improves the paving quality of the concrete pavement.

[0021] 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.

[0022] Please see Figures 1-4In this utility model, a municipal road smoothing machine includes a fixed base 1. Two sets of first threaded rings 2 are embedded on the upper surface of the fixed base 1. An adjusting mechanism 3 is connected to the inner ring of each first threaded ring 2. A U-shaped scraper 4 is connected to the bottom surface of the fixed base 1. A set of equally spaced scraper needles 5 are also connected to the bottom surface of the fixed base 1. A groove 6 is formed in the inner top wall of the fixed base 1. A drive motor 7 is installed inside the groove 6. A connecting rod 8 is connected to the output end of the drive motor 7. A smoothing plate 9 is connected to the bottom end of the connecting rod 8. Two push handles 10 are connected to the right side of the fixed base 1. Each adjusting mechanism 3 includes a threaded screw 301. A rotating handle 302 is connected to the top end of each threaded screw 301. Each threaded screw 301 is equipped with a caster wheel 303 below it. The upper surface of each caster wheel 303 is inlaid with a second threaded ring 304. The inner ring of each second threaded ring 304 is connected to the outer surface of each threaded screw 301. By turning the handle 302, the threaded screw 301 can be driven to rotate within the inner ring of the first threaded ring 2. This rotation of the threaded screw 301 within the inner ring of the first threaded ring 2 can drive the fixed seat 1 to move up and down, thereby causing the fixed seat 1 to drive the U-shaped scraper 4, scraper needle 5, and trowel 9 to move up and down. This allows adjustment of the height of the U-shaped scraper 4, scraper needle 5, and trowel 9 from the ground, making it convenient for workers to adjust the thickness of the concrete pavement.

[0023] A control panel 11 is installed on the right side of the fixed base 1. A spirit level 12 is installed on the upper surface of the fixed base 1. A placement groove 18 is opened on the upper surface of the fixed base 1. A counterweight plate 13 is placed inside the placement groove 18. The spirit level 12 allows the staff to easily check whether the fixed base 1 is in a horizontal state. The counterweight plate 13 can provide a certain amount of gravity for the fixed base 1.

[0024] The bottom surface of the fixed base 1 is provided with an annular groove 14, and an annular plate 15 is slidably connected inside the annular groove 14. The bottom end of the annular plate 15 is connected to the upper surface of the trowel 9. A battery 16 is installed on the upper surface of the fixed base 1, and a toolbox 17 is connected to the upper surface of the fixed base 1. By using the cooperation of the annular groove 14 and the annular plate 15, the trowel 9 can be limited, so that the trowel 9 can rotate more smoothly. The toolbox 17 can be used to facilitate the storage of various maintenance tools by the staff.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the operator first uses the rotating handle 302 to drive the threaded screw 301 to rotate inside the first threaded ring 2, which in turn causes the fixed seat 1 to drive the U-shaped scraper 4, scraper needle 5, and trowel 9 to rise and fall. This allows adjustment of the distance between the U-shaped scraper 4, scraper needle 5, and trowel 9 and the ground. After the distance between the U-shaped scraper 4, scraper needle 5, and trowel 9 and the ground is adjusted, the operator uses the control panel 11 to start the drive motor 7, which drives the connecting rod 8 and trowel 9 to rotate. At this time, the operator uses the push handle 10 and the universal wheel 303 to push the device forward. This allows the scraper needle 5 to break up sand holes and air bubbles inside the concrete, and the U-shaped scraper 4 to perform initial leveling of the concrete. Then, the rotation of the trowel 9 is used to smooth the concrete surface. The above is the complete operation procedure of this device.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
