Description

Mounting mechanism of wear-resisting plate of grader Technical Field The utility model relates to the technical field of graders, in particular to a mounting mechanism of a wear-resisting plate of a grader. Background In the working device of the land leveller, the wear-resisting plate is a key component for connecting the traction frame and the rotary ring and is used for reducing the abrasion between the traction frame and the rotary ring and ensuring the normal operation of equipment. Graders are earthmoving machines for levelling the ground, whose working devices need to be rotated and moved frequently, so that the performance and mounting of the wear plates are critical for the stability and service life of the equipment. In the conventional land leveler working device, the wear-resisting plate is usually mounted by simple bolts, and the wear-resisting plate is fixed on the traction frame by the bolts by arranging corresponding hole sites on the traction frame and the wear-resisting plate so as to realize the connection between the wear-resisting plate and the traction frame and the rotary ring. However, this conventional mounting has a number of problems. Firstly, the wear-resisting plate is easy to be assembled difficultly in the installation process, and as the wear-resisting plate is a flat thin plate, the wear-resisting plate is not fixed below the installation wire holes and naturally sags, and is not easy to center, the installation efficiency is low. Secondly, the bolts partially penetrate into the wear-resistant plate, so that the use efficiency of the wear-resistant plate is extremely low, and the effective use area of the wear-resistant plate is greatly limited because the thickness of the rear bottom plate of the traction frame is different and the penetration length of the bolts is only a few millimeters. In addition, the area of the bolt baffle wear-resisting plate is small, the wear-resisting plate is easy to scrape and destroy when stressed, and the wear-resisting plate naturally drops on the lower rotating ring to be placed, so that the phenomenon that the wear-resisting plate is gnawed by the rotating ring easily occurs when the bolt baffle wear-resisting plate is used, the wear-resisting plate is more easily damaged and falls off, and the service life and the working efficiency of equipment are seriously influenced. For this purpose, a mounting mechanism for a wear plate of a grader is proposed. Disclosure of utility model The utility model aims to solve the problems in the background art, and provides a mounting mechanism of a wear plate of a grader. The utility model specifically adopts the following technical scheme that the mounting mechanism of the wear-resisting plate of the land leveler is used for mounting the wear-resisting plate in the middle of a working device of the land leveler and comprises the following components: the bottom plate of the traction frame is provided with a sliding groove; The wear-resisting plate is placed in the sliding groove of the traction frame bottom plate; the upper plane of the rotary ring is tightly attached to the lower surface of the wear-resistant plate; the locking device is used for connecting the rotary ring, the wear-resisting plate and the traction frame into a whole; The guide bracket is used for extruding the wear-resisting plate between the traction frame bottom plate sliding groove and the upper surface of the revolving ring; the worm gear case is used for providing torque input for the rotary ring and driving the rotary ring to rotate relative to the traction frame; and the side wear-resistant plate is used for connecting the guide bracket with the wear-resistant plate of the inner side surface slideway of the rotary ring in a transitional manner. Further, the wear-resistant plate is a low-friction-coefficient engineering plastic plate. Further, the sliding groove of the traction frame bottom plate is matched with the shape of the wear-resisting plate, so that the position of the wear-resisting plate in the sliding groove can be limited. Further, the locking device comprises a locking bolt. Further, the number of the locking bolts is multiple, and the locking bolts are uniformly distributed on the traction frame bottom plate. Further, the guide bracket is shaped and dimensioned to cooperate with the wear plate and traction frame floor chute to securely compress the wear plate between the chute and the upper surface of the swivel ring. Further, the side wear plates are made of engineering plastics with low friction coefficient. Further, the shape of the side wear-resistant plate is matched with the shapes of the guide bracket and the inner side surface slideway of the rotary ring, so that good matching between the side wear-resistant plate and the guide bracket and the inner side surface slideway of the rotary ring can be ensured.
