[0031] Preferably, the inner surface of the arc-shaped guide groove 205a is in sliding fit with the outer surface of the guide block 205c, so as to realize the angle adjustment of the guide rod 205d.

[0032] When the ground of different heights or slopes needs to be scraped, the inclination angle of the scraper 104 can be adjusted by the adjusting assembly 205, the cylinder 202 is started, the output end of the cylinder 202 drives the fixed sleeve 203 to move along the fixed frame 201, the fixed sleeve 203 in turn drives the fixed block 204 to move synchronously, the arc-shaped guide groove 205a formed on the surface of the fixed block 204 is in sliding fit with the guide block 205c, the guide block 205c is pushed to slide along the groove, the guide block 205c drives the driving shaft 205b fixedly connected thereto to rotate, the driving shaft 205b further drives the guide rod 205d connected thereto to deflect, so as to adjust the working angle of the scraper 104 as a whole, so as to adapt to the requirements of the fine leveling of different ground elevations or design slopes.

[0033] It should be noted that one end of the driving shaft 205b penetrates through the fixed frame 201 and is fixedly connected with the guide block 205c, the other end of the guide block 205c is rotatably connected with the outer surface of the fixed frame 201, and a bearing is arranged at the connection between the driving shaft 205b and the fixed frame 201.

[0034] In use, first of all, the device is moved to the construction area by the roller 103, the scraper 104 is located on one side of the fixed plate 101, and is used for scraping the concrete or leveling layer material after paving, when different ground elevations or design slopes (such as drainage slopes) need to be adapted, the working angle of the scraper 104 can be automatically adjusted by the adjusting assembly 205, the cylinder 202 is started, the output end of the cylinder 202 pushes the fixed sleeve 203 to move linearly along the fixed frame 201, the fixed sleeve 203 drives the fixed block 204 to move synchronously, the arc-shaped guide groove 205a on the fixed block 204 is in sliding fit with the guide block 205c, so as to force the guide block 205c to slide along the groove, in turn drive the driving shaft 205b to rotate around its axis, the rotary motion of the driving shaft 205b is transmitted through the guide rod 205d connected with the outer surface of the driving shaft 205b, so that the guide rod 205d deflects, finally drives the scraper 104 to tilt as a whole, realizes the accurate adjustment of the scraping angle, the driving mechanisms 200 symmetrically arranged on both sides of the device ensure that the force is uniform during the adjustment process, the operation is stable, and the eccentric load is avoided, at the same time, the tool box 102 can be used to store commonly used tools, so as to facilitate the on-site maintenance, the scraper 104 can be quickly installed and disassembled through the quick release assembly 206, so as to facilitate the replacement of worn parts or the adaptation to different working conditions, and the use flexibility and maintenance efficiency of the device are improved.

[0035] In summary, by driving the fixed block 204 to move through the cylinder 202, the sliding cooperation between the arc-shaped guide groove 205a and the guide block 205c drives the driving shaft 205b to rotate, and then the working angle of the guide rod 205d and the scraper 104 is accurately adjusted, which can adapt to the fine leveling requirements of different slope or elevation ground, and improve the moving convenience and on-site practicability of the equipment in cooperation with the roller 103 and the tool box 102. Embodiment 2

[0036] With reference to Figs. 3-5 For the second embodiment of the application, the difference between this embodiment and the first embodiment is that the worn leveling plate is quickly disassembled to avoid the cumbersome way of traditional bolted installation.

[0037] Further, the quick-release assembly 206 includes a threaded rod 206a threadedly connected with the guide rod 205d, a sliding rod 206b in sliding cooperation with the inner surface of the threaded rod 206a, a fixed sheet 206c fixedly connected with the outer end surface of the sliding rod 206b, a spring 206d fixedly connected with the outer surface of the fixed sheet 206c, a positioning block 206e rotationally connected with the outer surface of the sliding rod 206b, an internally-threaded knob 206f threadedly connected with the threaded rod 206a, and a pull ring 206g fixedly installed on the outer surface of the threaded rod 206a.

[0038] When the scraper 104 needs to be replaced due to wear, first, the internally-threaded knob 206f is rotated to separate it from the surface of the guide rod 205d, releasing the axial locking, then the sliding rod 206b is pressed, the sliding rod 206b drives the fixed sheet 206c to move inward, compressing the spring 206d, so that the positioning block 206e is guided inwardly by the recovery groove and is separated from the abutting state with the surface of the scraper 104, then the pull ring 206g is rotated to drive the threaded rod 206a to rotate along the internally-threaded groove of the guide rod 205d and exit, thereby releasing the fixation of the scraper 104, after removing the old scraper, a new scraper is installed, and the replacement can be completed by operating in the reverse order, without the need for additional tools, which is convenient and efficient.

[0039] Further, the threaded rod 206a penetrates the guide rod 205d and the scraper 104 in sequence, and the inner surface of the guide rod 205d is provided with a threaded groove matched with the threaded rod 206a.

[0040] Further, the outer surfaces of the sliding rod 206b and the fixed sheet 206c are in sliding cooperation with the inner surface of the threaded rod 206a, and the other end of the spring 206d is fixedly connected with the inner surface of the threaded rod 206a.

[0041] Preferably, the positioning blocks 206e are annularly and uniformly distributed on the outer surface of the fixed sheet 206c, the positioning blocks 206e are hingedly installed with the fixed sheet 206c, and the positioning blocks 206e abut against the surface of the scraper 104.

[0042] Need to explain, the outer surface of the threaded rod 206a is provided with a recovery groove matched with the positioning block 206e, realizing the opening and recovery action of the positioning block 206e, and the inner threaded knob 206f is in surface abutment with the guide rod 205d.

[0043] In use, when the scraper 104 needs to be replaced due to long-term operation and wear, the disassembly and assembly operation can be quickly completed without the aid of any tool. First, rotate the inner threaded knob 206f to make it exit along the threaded rod 206a, thereby releasing its axial abutment state with the end surface of the guide rod 205d. Then, press the sliding rod 206b, which drives the fixed plate 206c to move inwardly along the threaded rod 206a, thereby compressing the spring 206d. Under the action of the compressed spring 206d, the multiple positioning blocks 206e, which are hinged to the fixed plate 206c, are guided by the recovery groove and synchronously folded inwardly, thereby disengaging from the abutment locking state with the surface of the scraper 104. Next, rotate the pull ring 206g to drive the entire threaded rod 206a to rotate in the inner threaded groove of the guide rod 205d and axially exit, until it completely disengages from the mounting hole of the scraper 104. The old scraper 104 can be removed. When installing a new scraper 104, the scraper 104 is sleeved into the threaded rod 206a, the pull ring 206g is reversely rotated to make the threaded rod rotate into the guide rod 205d and be in place. At this time, the positioning blocks 206e are automatically opened and clamped to the end surface of the scraper under the elastic force of the spring 206d. Finally, the inner threaded knob 206f is rotated again to tightly abut against the surface of the guide rod 205d, thereby realizing double locking and ensuring firm and reliable connection.

[0044] In summary, through the mutual cooperation of the various components of the quick release assembly 206, the scraper 104 is quickly replaced. The threaded rod 206a and the guide rod 205d are axially fed by thread cooperation. The spring 206d is compressed by pressing the sliding rod 206b, which drives the positioning blocks 206e to fold under the guidance of the recovery groove, thereby disengaging from the scraper 104. The axial locking of the inner threaded knob 206f ensures reliable connection. The entire process does not require tools, is convenient to operate, and improves the maintenance convenience and construction continuity of the equipment.
