Description

Technical Field

[0001] The utility model relates to the technical field of coal machine scrapers, in particular to a coal machine scraper with high tensile strength. Background Art

[0002] The most important thing after coal mining is to transport it out in time. In the process of transporting coal from underground to the ground, a coal mine scraper conveyor is needed. This type of equipment is widely used because of its large transportation capacity, small body height, easy loading, convenient body telescopic, easy relocation and strong body. The coal machine scraper is the main load-bearing component on the coal mine scraper conveyor for scraping and transporting coal.

[0003] Since the coal machine scraper is often composed of only a single metal material, it cannot improve its tensile and crack resistance through multi-level reinforcement structure composite, and there is also the problem of poor wear resistance and anti-sticking effect of the outer wall. In addition, it is often directly welded to the traction chain of the coal mine scraper conveyor or fixed and installed by screws. The former is difficult to disassemble and maintain, and the latter has poor flexibility and difficulty in adjusting the installation position, which can no longer meet people's needs. For this reason, we propose a new type of high tensile strength coal machine scraper to solve the above-mentioned defects. Utility Model Content

[0009] Furthermore, two of the first mounting seats and two of the second mounting seats are provided, and one side of the adjusting slide rod is welded to the outer reinforcing protective sleeve.

[0010] Furthermore, the tops of the first mounting seat and the second mounting seat are evenly threadedly connected with threaded limiters for pressing and adjusting the sliding rod.

[0011] Furthermore, an elastic clamping assembly is installed at the top end of the first mounting seat and the second mounting seat, and the elastic clamping assembly includes a connecting spring, and the connecting spring is welded at a middle position of the top end of the first mounting seat and the second mounting seat.

[0012] Furthermore, the elastic pressing assembly also includes a pressing block and an anti-slip rubber sheet. The pressing block is welded to the bottom of the connecting spring, and the anti-slip rubber sheet is vulcanized and connected to the bottom of the pressing block.
