Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a scraper machine for mining. Background Art

[0002] Mining machinery is core equipment in mining production and is widely used in coal mines, metal mines, and other operations. With the advancement of mining technology, mechanized operations have gradually replaced manual operations, improving production efficiency. There are many types of mining machinery, including coal miners, roadheaders, and scraper conveyors. Among them, scraper conveyors use mechanical transmission to transport ore or coal from the mining point to the designated area. They have the advantages of simple structure, stable operation, and strong adaptability. Scrapers exhibit good wear resistance and impact resistance in the complex environment of mines, especially when handling hard ores, and can meet the needs of long-distance and high-load transportation. Therefore, scraper conveyors play an indispensable role in mining machinery.

[0003] Deficiencies of existing technology:

[0004] In coal mines and hard metal mines, the continuous friction between the scraper and the ore during conveying by a scraper conveyor generates dust. Prolonged retention of this dust within the mine can have significant health consequences for miners. Dust particles remain suspended in the air and are easily inhaled by workers. Long-term exposure to dust can lead to respiratory illnesses and even occupational diseases such as silicosis. Utility Model Content

[0028] Example

[0029] See also Figure 1-5 As shown, the utility model provides a technical solution for a scraper for mining: a scraper for mining, comprising a frame 1, positioning plates 2 are installed on both sides of the frame 1, movable grooves 3 are provided inside the positioning plates 2, and a shield mechanism 4 is fixedly installed inside the movable groove 3 by a bolt assembly, and a driving mechanism 5 is installed at the end of the frame 1;

[0030] The shield mechanism 4 includes a first shield 401 and a second shield 403. Both sides of the first shield 401 are fixedly connected to the movable groove 3 by a bolt assembly. The first shield 401 is located directly above the frame 1. Both ends of the first shield 401 are designed with outward-turning pressure edges 402. Both sides of the second shield 403 are fixedly connected to the movable groove 3 by a bolt assembly. The second shield 403 is located directly above the frame 1. Both ends of the second shield 403 are designed with inward-turning pressure edges 404. The second shield 403 is sleeved on the outside of the first shield 401. A gap for gas to pass through is reserved between the inner side walls of the first shield 401 and the second shield 403 and the frame 1. When installing the shield mechanism 4, the two first shields 401 need to be placed on the frame 1, and roughly maintain a distance of the second shield 403. Then, the installation on both sides of the two first shields 401 The hole is aligned with the movable slot 3, and the outermost first guard cover 401 is fixed first (first put a gasket on the mounting hole, put a bolt in the hole, and then put a nut on the part of the bolt protruding from the bottom of the movable slot 3 and tighten it), then place the second guard cover 403 on the upper end of the two first guard covers 401, and make one outward-turned pressure edge 402 of the fixed first guard cover 401 abut against the inward-turned pressure edge 404 of the second guard cover 403, and then fix the second guard cover 403, and then drag the unfixed first guard cover 401, so that the other inward-turned pressure edge 404 of the second guard cover 403 abuts against the outward-turned pressure edge 402 of the first guard cover 401, and fix it. After that, each guard cover is fixed in this way. When the last guard cover is fixed and the free space on the frame 1 cannot meet the condition that the pressure edges of the two guard covers abut each other, it can be directly put on and fixed.

[0031] A through slot 6 is provided on the positioning plate 2, and the through slot 6 is located directly below the gap between the first protective cover 401, the second protective cover 403 and the frame 1, and a collection slot 7 is installed at the bottom of the through slot 6; this design can provide effective air circulation inside the protective cover, prevent excessive accumulation of internal mine dust, and reduce the risk of mine dust explosion. At the same time, the collection slot 7 set at the bottom of the through slot 6 can effectively collect the mine dust inside the protective cover, facilitate centralized processing, and optimize the maintenance convenience of the equipment.

[0032] An observation window 8 is provided on the second protective cover 403. During the specific implementation process, the observation window 8 can be made of an anti-static transparent plate (such as anti-static glass, anti-static acrylic plate, etc.); this design ensures the operator's visibility of the inside of the protective cover, while effectively preventing static electricity accumulation, further improving the safety performance of the equipment.

[0033] A scraper 9 is installed on the driving mechanism 5, and a push plate 10 is fixedly installed on the upper end surface of the scraper 9; in the specific implementation process, the driving mechanism 5 may include a motor, a chain belt and a roller with a chain belt groove. The scraper 9 is fixed on the chain belt. Its working principle is that the motor drives the roller to rotate, and the chain belt groove on the roller remains engaged with the chain belt, so that the scraper 9 is driven to circle around the frame 1 in a circular motion to transport minerals. Installing a push plate 10 on the upper end of the scraper 9 can provide a larger release area, so that the minerals will not fall back when it is transported upward on the slope, thereby improving the transportation efficiency and safety.

[0034] The distance between the collection trough 7 and the through groove 6 is 5-10 cm. This design optimizes the outlet space of the gap between the shield and the frame 1, avoids the collection trough 7 from obstructing the air flow channel, ensures that the gas inside the shield can flow smoothly, thereby improving the overall ventilation effect and reducing the risk of dust accumulation.

[0035] The working principle of this utility model is as follows:

[0036] When installing a mining scraper according to this embodiment, first place the two first shields 401 on the frame 1, maintaining an appropriate spacing. Then, align the mounting holes of the two first shields 401 with the movable slots 3, and secure the outermost first shield 401 with bolts and nuts to ensure its stability. Next, fit the second shield 403 over the outer edges of the two first shields 401, and connect them entirely by utilizing the interplay of the outward-turned pressure edges 402 and the inward-turned pressure edges 404, completing the installation.

[0037] When in use, the gap formed between the shield and the frame 1 provides an airflow channel, promotes air circulation, prevents the accumulation of mineral dust inside the shield, and reduces risks. The collection trough 7 at the lower end of the gap can realize the centralized collection of mineral dust, providing convenience for subsequent processing.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
