Scraper blade assembly with protective structure

Abstract

The utility model relates to the field of mining scraper conveying equipment, in particular to a scraper assembly with a protective structure. The device comprises a special scraper, a cross beam, a fixing pin, a protective cover, an O-shaped ring, a bolt and a nut. A new solution is provided for protection of the bolt and the nut in the scraper assembly, the O-shaped ring, the protective cover and the fixing pin are additionally arranged in the scraper assembly, a protective structure is formed outside the bolt and the nut, and impact and damage of gangue and large coal to the bolt and the nut for the scraper can be effectively prevented; the problems that coal slime, pulverized coal and the like enter the connecting position of the bolt and the nut, so that the bolt and the nut are rusted and stuck, and cannot be normally disassembled and assembled are solved, and therefore the bolt and the nut are protected.

Description

Technical Field

[0001] This utility model relates to the field of scraper conveying equipment for mining, specifically to a scraper assembly with a protective structure. Background Technology

[0002] The scraper chain is a crucial component of mine scraper conveyor equipment. It meshes with sprockets to move the coal on the conveyor's plates. Scraper conveyors operate under harsh conditions, containing large amounts of dust, coal slurry, and groundwater with highly corrosive elements. This causes corrosion and jamming of the bolts and nuts used in the scraper chain, making them difficult to disassemble and replace. Furthermore, the impact and damage from gangue and large pieces of coal on the bolts and nuts leads to loosening or even breakage, severely affecting the reliability of the scraper chain. This invention provides a scraper assembly with a protective structure to solve the problem of protecting the bolts and nuts in scraper assemblies. Summary of the Invention

[0003] The purpose of this invention is to provide a scraper assembly with a protective structure to solve the problem of protecting bolts and nuts in scraper assemblies.

[0004] A scraper assembly with a protective structure includes a special scraper 1, a crossbeam 2, a fixing pin 3, a protective cover 4, an O-ring 5, a bolt 6, and a nut 7. The special scraper 1 is connected to the crossbeam 2 by the bolt 6 and the nut 7.

[0005] The bolt groove sidewall of the special scraper 1 is at a 90° angle to the bottom surface, and the bolt groove sidewall has a groove for placing the O-ring 5. The protective cover 4 is placed in the bolt groove, sealed and tightened by the O-ring 5, and limited by the fixing pin 3 that passes through the bolt 6.

[0006] The beneficial effects of this utility model are: a protective cover is installed on the scraper assembly, and the protective cover is limited and fixed by O-rings and fixing pins. The protective cover protects the bolts and nuts, preventing dust and coal slurry from entering the bolt groove and causing the bolts and nuts to rust and jam; it also prevents gangue and large pieces of coal from impacting and damaging the bolts and nuts of the scraper, thus improving the performance of the equipment.

[0010] 1. Special scraper, 2. Crossbeam, 3. Fixing pin, 4. Protective cover, 5. O-ring, 6. Bolt and 7. Nut. Detailed Implementation

[0011] exist Figure 1 In the middle, special scraper 1, crossbeam 2 and Figure 2 The bolts 6 are connected together and tightened by nuts 7. The bolt groove sidewall of the special scraper 1 is at a 90° angle to the bottom surface, and the bolt groove sidewall has a groove for placing the O-ring 5. Figure 2 In this assembly, the protective cover 4 is placed in the bolt groove, sealed and tightened by the O-ring 5, and limited by the retaining pin 3 that passes through the bolt 6. The nut 7 is placed inside the protective cover 4. During equipment use, the protective cover protects the bolts and nuts, preventing dust and coal sludge from entering the bolt groove and causing corrosion or jamming; it also prevents impact and damage to the bolts and nuts of the scraper from gangue and large pieces of coal, improving the service life and reusability of the bolts and nuts in the scraper assembly, thereby improving the performance of the equipment.
