However, the current site leveling device can only perform horizontal operations through the scraper with a fixed angle, and cannot flexibly adjust the inclination angle of the scraper according to actual needs, thereby making it difficult to meet the requirements of slope construction. This limitation leads to the fact that when the site needs to be leveled with a slope, the construction personnel have to rely on manual adjustment or other auxiliary equipment, which not only increases the construction difficulty, but also reduces the work efficiency. Therefore, there is an urgent need for a site leveling device that can adapt to different slope requirements to improve the flexibility and applicability of construction. SUMMARY

Specific implementation

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only 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 labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-5 The present application provides a site leveling device, which comprises a mounting frame 1, a bearing frame 2, a hydraulic telescopic rod 3 and a scraper 4. The mounting frame 1 is fixedly connected to a vehicle body (not shown in the figure), and the bearing frame 2 is installed on the mounting frame 1 through a rotary connection, so that the bearing frame 2 can rotate relative to the mounting frame 1. The mounting frame 1 is fixedly connected with a first branch 101, and the bearing frame 2 is fixedly connected with a second branch 201. One end of the hydraulic telescopic rod 3 is connected to the first branch 101 through a rotary connection, and the other end is connected to the second branch 201 through a rotary connection, thereby forming an adjustable linkage structure. The scraper 4 is fixedly connected to the bearing frame 2 and is used for scraping and leveling the surface of the site.

[0022] In use, the hydraulic telescopic rod 3 is started, and the telescopic movement of the hydraulic telescopic rod 3 drives the second branch 201 to rotate relative to the first branch 101. Since the second branch 201 is fixedly connected to the bearing frame 2, the bearing frame 2 rotates relative to the mounting frame 1. The rotation of the bearing frame 2 further drives the scraper 4 to rotate around its connection point, thereby achieving angle adjustment of the scraper 4. By adjusting the telescopic length of the hydraulic telescopic rod 3, the inclination angle of the scraper 4 can be accurately controlled, so that it can adapt to the site leveling requirements of different slopes.

[0023] The site leveling device has the advantages that the linkage design of the hydraulic telescopic rod 3 and the supporting arm realizes flexible adjustment of the angle of the scraper 4, can meet the leveling requirements of the horizontal site, can also meet the site construction requirements of the site with a slope, significantly improves the flexibility and efficiency of construction, and has high practicability and popularization value.

[0024] In the embodiment, a plurality of mounting portions 102 are arranged on the mounting frame 1, specifically three mounting portions 102, and mounting holes 103 are arranged on each mounting portion 102. The mounting holes 103 are used for fixing and connecting the mounting frame 1 to a vehicle body (not shown in the figure) by bolts or other fasteners, so as to realize stable connection of the site leveling device and the vehicle body. The three mounting portions 102 are distributed in a triangular shape, which can effectively improve the stress uniformity and overall stability of the mounting frame 1, and ensure that the device remains firm during operation.

[0025] Further, the bearing frame 2 is provided with a locking assembly 5. The scraper 4 is installed on the bearing frame 2 in a rotary connection mode, so that the scraper 4 can rotate relative to the bearing frame 2. The locking assembly 5 is used to lock the scraper 4 after it is adjusted to the target angle, so as to prevent accidental deviation during operation. Specifically, the locking assembly 5 can include locking bolts, buckle structures or other mechanical locking devices, and the fixation of the scraper 4 is realized by manual or automatic operation. The design of the locking assembly 5 not only improves the stability of the scraper 4 in the working state, but also enhances the safety and reliability of the device.

[0026] In the embodiment, the lower surface of the bearing frame 2 is provided with a gear 6 in a rotary connection mode. The lower surface of the gear 6 is fixedly connected with a mounting beam 7, and the lower part of the mounting beam 7 is fixedly connected with the scraper 4. Through the rotation of the gear 6, the mounting beam 7 can drive the scraper 4 to rotate around the connection point, so as to realize the adjustment of the angle of the scraper 4. The locking assembly 5 is used to lock the gear 6, so as to prevent accidental deviation of the scraper 4 during operation, and ensure its stability and safety.

[0027] Specifically, the locking assembly 5 comprises a cylinder 501, two sleeves 502, two guide shafts 503, two springs 504 and a locking plate 505. The cylinder 501 is fixedly connected with the seat plate 202 of the bearing frame 2 and is used for providing driving power. The two sleeves 502 are sleeved on the guide shafts 503 respectively, the guide shafts 503 are in sliding connection with the sleeves 502, so that the guide shafts 503 can slide in the sleeves 502 in the axial direction. The two springs 504 are sleeved on the guide shafts 503 respectively, one end of the spring 504 is connected with the guide shaft 503, and the other end is fixedly connected with the sleeve 502. The sleeve 502 is fixedly connected with the seat plate 202 and is used for supporting the guide shaft 503 and the spring 504. The locking plate 505 is fixedly connected with the two guide shafts 503, and the locking plate 505 is provided with a clamping tooth 506 which is engaged with the gear 6.

[0028] In use, the cylinder 501 is started, and the output end of the cylinder 501 drives the locking plate 505 to move. The locking plate 505 drives the guide shaft 503 to slide relative to the sleeve 502, while the spring 504 is compressed. At this time, the clamping tooth 506 of the locking plate 505 is separated from the gear 6, and the locking of the gear 6 is cancelled. Then, the operator can rotate the mounting beam 7 and the scraper 4 to further adjust the angle of the scraper 4 to meet the leveling requirements of different slope sites.

[0029] When the angle adjustment of the scraper 4 is completed, the output end of the cylinder 501 is controlled to retract. Under the action of the restoring force of the spring 504, the guide shaft 503 drives the locking plate 505 to reset, so that the clamping tooth 506 of the locking plate 505 is re-engaged with the gear 6, and the locking of the gear 6 is realized. At this time, the angle of the scraper 4 is fixed, which ensures that it remains stable during operation.

[0030] Through the above structure, the site leveling device of the utility model not only can realize flexible adjustment of the angle of the scraper 4, but also can reliably lock the gear 6 through the locking assembly 5, which improves the stability and safety of the device and is suitable for leveling operation in various complex sites.

[0031] It should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.
