Description

Land leveler shovel sword mounting structure Technical Field The utility model relates to the technical field of graders, in particular to a grader shovel blade mounting structure. Background The blade of the shovel blade is worn most seriously due to direct contact with soil in the long-term use process. The abrasion form of the blade is mainly represented by gradually reducing the thickness, and as the blade is fixed at the bottom of the blade body by the bolts, when the blade is abraded and reduced, the bolts for fixing the blade can protrude out of the blade, so that the bolts are loosened, the working efficiency of the blade is affected, and the service life of the blade is shortened. Disclosure of utility model In order to solve the problems mentioned in the background art, the utility model aims to provide a land leveler shovel blade mounting structure. In order to achieve the above object, the technical scheme of the present utility model is as follows: The utility model provides a land leveller shovel sword mounting structure, includes shovel cutter body and blade, the positive bottom of shovel cutter body is thinned and is formed the mounting groove, the blade cooperation is installed in the mounting groove, the back of shovel cutter body corresponds the blade laminating has the splint, the blade the shovel cutter body with the splint jointly pass through many first bolts and first nut locking, the head of first bolt is located in the blade, supply on the shovel cutter body the hole that first bolt passed is the bar hole, the bar hole vertically sets up, supply on the splint the hole that first bolt passed is the round hole, the size of round hole with the screw thread portion of first bolt matches, the bottom of the back of shovel cutter body is provided with horizontal bead, the bottom butt of splint is in the top of bead, the positive upper portion of shovel cutter body is through many second bolts and second nut subsides and is installed the stiffening plate, the bottom laminating of stiffening plate is in the upper portion of the front of blade and with the head of first bolt is covered. Further, a plurality of the first bolts are transversely arranged. Further, a plurality of the second bolts are arranged in a rectangular shape. Further, the head of the second bolt is arranged in the hardening plate. Further, the first bolt and the second bolt are square neck bolts. The utility model has the beneficial effects that the upper part of the blade and the first bolt for fixing the blade are covered by the hardening plate, so that the loosening of the first bolt caused by abrasion can be effectively avoided, and the stability of the installation of the blade is ensured; the strip-shaped holes are also convenient for disassembling and assembling the blade, and a specific disassembling and assembling process is described in the embodiment. Drawings FIG. 1 is a perspective view of an embodiment of the present utility model; FIG. 2 is an exploded view of an embodiment of the present utility model; Fig. 3 is a cross-sectional view of an embodiment of the present utility model.
