Description

Technical Field

[0001] This utility model relates to the field of grader technology, and in particular to a grader blade mounting structure. Background Technology

[0002] During prolonged use, the blades of a shovel experience the most severe wear due to their direct contact with the soil. This wear primarily manifests as a gradual thinning of the blade. Since the blades are bolted to the bottom of the shovel body, as the blades wear down, the bolts protrude beyond the blade, causing them to loosen. This not only affects the shovel's working efficiency but also shortens its service life. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a grader blade mounting structure.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A grader blade mounting structure includes a blade body and a blade. The bottom of the front side of the blade body is thinned to form a mounting groove, and the blade is fitted into the mounting groove. A clamping plate is attached to the back side of the blade body corresponding to the blade. The blade, the blade body, and the clamping plate are locked together by multiple first bolts and first nuts. The head of the first bolt is located inside the blade. The hole on the blade body through which the first bolt passes is a strip-shaped hole, which is arranged longitudinally. The hole on the clamping plate through which the first bolt passes is a round hole, the size of which matches the threaded portion of the first bolt. A transverse protrusion is provided at the bottom of the back side of the blade body, and the bottom of the clamping plate abuts against the top of the protrusion. A hardening plate is attached to the upper part of the front side of the blade body by multiple second bolts and second nuts. The bottom of the hardening plate is attached to the upper part of the front side of the blade and covers the head of the first bolt.

[0006] Furthermore, multiple of the first bolts are arranged laterally.

[0007] Furthermore, multiple second bolts are arranged in a rectangular pattern.

[0008] Furthermore, the head of the second bolt is located inside the hardened plate.

[0009] Furthermore, both the first bolt and the second bolt are square neck bolts.

[0010] The beneficial effects of this utility model are as follows: by covering the upper part of the blade and the first bolt fixing the blade with the hardening plate, the first bolt can be effectively prevented from loosening due to wear, thus ensuring the stability of the blade installation; the setting of the strip hole also facilitates the disassembly and assembly of the blade, and the specific disassembly and assembly process will be described in the embodiments.

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] like Figures 1-3 As shown, a grader blade mounting structure includes a blade body 1 and two blades 2. The bottom of the front side of the blade body 1 is thinned to form a mounting groove 11. The two blades 2 are fitted into the mounting groove 11. A clamping plate 3 is attached to the back side of the blade body 1 corresponding to each blade 2. The blades 2, blade body 1, and clamping plates 3 are locked together by four first bolts 4 and four first nuts 5. The heads of the first bolts 4 are located inside the blades 2. The holes on the blade body 1 through which the first bolts 4 pass are strips. The shaped hole 12 and the strip hole 12 are arranged longitudinally. The hole on the clamping plate 3 for the first bolt 4 to pass through is a round hole 31. The size of the round hole 31 matches the thread of the first bolt 4. A transverse convex rib 13 is provided at the bottom of the back of the scraper body 1. The bottom of the clamping plate 3 abuts against the top of the convex rib 13. A hardening plate 8 is attached to the upper part of the front of the scraper body 1 by multiple second bolts 6 and second nuts 7. The bottom of the hardening plate 8 is attached to the upper part of the front of the blade 2 and covers the head of the first bolt 4.

[0017] By covering the upper part of the blade 2 and the first bolt 4 that fixes the blade 2 with the hardening plate 8, the loosening of the first bolt 4 due to wear can be effectively prevented, ensuring the stability of the blade 2 installation. When disassembling the blade 2, unscrew the first nut 5, then remove the clamping plate 3, and pull the blade 2 downward and then outward to easily remove the blade 2. When installing the blade 2, first pass the first bolt 4 through the blade 2, then pass the first bolt 4 through the strip hole 12 and push the blade 2 upward so that the blade 2 is clamped between the hardening plate 8 and the scraper body 1. Then, attach the clamping plate 3 to the back of the scraper body 1, and then tighten the first nut 5 to complete the installation of the blade 2. The hardening plate 8 does not need to be removed when installing or removing the blade 2.

[0018] In this embodiment, multiple first bolts 4 are arranged horizontally, which is a reasonable design and facilitates the coverage of the hardening plate 8.

[0019] In this embodiment, multiple second bolts 6 are arranged in a rectangular pattern, which is a reasonable design and facilitates stable fixation of the hardened plate 8.

[0020] In this embodiment, the head of the second bolt 6 is located inside the hardened plate 8, which is a reasonable design and avoids the head of the second bolt 6 being exposed and rubbing against the soil.

[0021] In this embodiment, both the first bolt 4 and the second bolt 6 are square neck bolts. Using square neck bolts can effectively prevent loosening and improve the stability of the installation of the hardened plate 8 and the blade 2.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
