Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to long wall type caving mining working face ore loading equipment. Background Art

[0002] Mining is the technology and science of mining mineral resources from the earth's crust and surface. Mining in a broad sense also includes the mining of coal and oil. The mining industry is an important raw material industry. Metallic ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials. The loading equipment of the longwall caving mining face is mainly used for the filling of the mine during the mining process, that is, the processing equipment of the mine waste. This equipment is mainly used for slag treatment after mining, mine spoil field leveling and mine restoration.

[0003] For example, a mining device with patent announcement number CN213315547U can use the collecting frame, screening net, vibrating first motor and conveyor belt to collect the crushed minerals by the collecting frame, and vibrate the first vibrating motor at the same time, so that the qualified minerals can pass through the screening net and fall onto the upper surface of the conveyor belt. The conveyor belt can be used to transport the qualified minerals to a designated location to complete the screening, thereby ensuring the quality of the mineral crushing, avoiding the problem that the traditional mining equipment cannot perform screening during the processing and crushing, and improving the practicality of the mining equipment.

[0004] Although the above equipment collects the crushed minerals through the cooperation of the collecting rack, the screening net, the vibrating first motor and the conveyor belt, the working face space is limited. In addition, since the ore is crushed into different sizes and has prominent edges and corners, it brings great inconvenience to the loading work of the working face. Large pieces often damage the conveyor or block the chute discharge port, and it is impossible to screen them. For this reason, we propose a new longwall caving mining working face loading equipment.

The loading equipment is inspected and maintained. A good ventilation system can effectively remove dust and harmful gases from the working face to ensure the health and safety of workers. Operators are trained and guided to ensure the smooth progress of loading operations and the safe operation of the working face, thereby maximizing production efficiency and work safety.

[0029] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a long wall type caving mining working face loading equipment, comprising:

[0030] The longwall caving mining working face loading device is composed of a mining mechanism 1, a screening mechanism 2, and a base 3;

[0031] A mining mechanism 1, arranged on the top of the base 3, is used for collecting data in the mining area;

[0032] The screening mechanism 2 is arranged on one side of the base 3 and is used for crushing and screening the collected ore.

[0033] Mining institutions1 include:

[0034] An electric push rod 110 is installed on the inner side of one end of the base 3, and a second scraper conveyor 109 is installed on one end of the electric push rod 110. Fixed seats 115 are installed on both sides of the base 3. A hydraulic rod 112 is installed on the right side of the fixed seat 115. The first scraper conveyor 101 is installed on the output end of the hydraulic rod 112. A counterweight block is installed in the middle of the top of the base 3.

[0035] Baffles 111 are installed on both sides of the top of the base 3, and multiple connecting plates 116 are installed on one side of the baffle 111 through fixing bolts 104. The other end of the connecting plate 116 is installed on the inner side of the bracket 105 through fixing bolts 104. A hydraulic rod 112 is installed at the bottom of the bracket 105, and the bottom end of the hydraulic rod 112 is installed at the top of the base 3.

[0036] A bottom beam 102 is installed at the right end of the bracket 105. The left side of the bottom beam 102 is an arc and is installed on the inner side of the bracket 105 by rotating the bolt 114. A clamping plate 103 is installed at the bottom end of the bottom beam 102. A hydraulic rod 112 is installed on the inner side of the clamping plate 103. A fixed seat 115 is installed at the other end of the hydraulic rod 112. The fixed seat 115 is located at the bottom end of the bracket 105.

[0037] A plurality of support plates 107 are installed at the left end of the bracket 105, a rotating frame 113 is installed at the bottom end of the support plate 107, the right side of the rotating frame 113 is installed on the inner side of the clamping plate 103 through a rotating bolt 114, a fixing plate 108 is installed at the bottom end of the rotating frame 113, a hydraulic rod 112 is installed at one end of the fixing plate 108, and the other end of the hydraulic rod 112 is installed at the bottom end of the bracket 105 through a fixing seat 115.

[0038] like Figure 2 As shown, it should be noted that: a mining machine is installed on the second scraper conveyor 109, and the mining machine works at the set bottom cutting height. The ore collected by the mining machine is transported out of the working surface through the second scraper conveyor 109. During the operation of the mining machine, the hydraulic rod 112 drives the rotating frame 113 to rotate. During the rotation of the rotating frame 113, the high-position ore is supported by the support plate 107. The base 3 of the device moves back and forth on the working surface, and the remaining ore above the ore cut by the mining machine will be induced to collapse, and the ore will fall on the unfolded bottom beam 102. After the bottom beam 102 is unfolded, it is slowly returned by the hydraulic rod 112. The ore falls on the first scraper conveyor 101, and the bottom beam 102 is opened and closed in a controlled manner to ensure that the first scraper conveyor 101 can be highly loaded to avoid transporting stones after all the ore is mined. After transporting the ore, the first scraper conveyor 101 is pulled toward the base 3 by the hydraulic rod 112. The mined stones will fill the space where the ore disappears under the action of gravity to form a collapsed area. The second scraper conveyor 109 is pushed forward by the electric push rod 110 to cut the ore for the next time. The electric push rod 110 drives the base 3 to move toward the second scraper conveyor 109, thereby driving the device to work on the working surface.
