Description

Technical Field

[0001] The invention relates to the technical field of ground boring machines, in particular to a ground boring machine with a dustproof structure. Background Art

[0002] In the field of mining equipment for solid deposits such as coal and rock, my country's mechanized mining equipment such as tunnel boring machines and continuous mining machines have reached a very high technical level, realizing safe and efficient horizontal mining of solid deposits, and are maturely applied to the mining of medium-thick and thick ore layers with near-horizontal, gently inclined, and medium-inclined deposits, and have achieved good technical and economic results. When it is applied to the mining of extra-thick solid deposits with a thickness greater than 30m, it is necessary to adopt a tunnel layout method of horizontal stratification and layer-by-layer mining along the thickness of the deposit, which directly reduces the resource recovery rate, the safety and reliability of the mine, and the technical and economic effects. If the mining method of horizontal advancement of mining equipment is changed to vertical advancement mining along the thickness of the deposit, the problem of safe and efficient mining of extra-thick solid deposits with a thickness greater than 30m can be solved, but the current tunnel boring drill bit of the tunnel boring machine is prone to generate coal dust during construction, which is more harmful to the operating workers.

[0010] Preferably, a through-hole column is embedded and installed on the inside of the through-hole cavity, and the through-hole cavity is wrapped and fixedly connected to one end of the ground excavation body through a fixing nut group, the connecting thread block is threadedly connected to the hollow block through a threaded through cylinder, and a slide groove is provided on the surface of the hollow block to facilitate the sliding adjustment of the dust-proof structural components, and a cleaning brush is fixedly installed on the inside of the hollow block, and a synchronous cylinder for driving and adjusting the dust-proof structural components is fixed on one side of the connecting thread block.

[0011] By adopting the above technical solution, the cleaning brush is provided to achieve relative rotation cleaning.

[0012] Preferably, the dust-proof structure includes a through frame with a slider fixed inside, and a connecting cover with a hollow structure inside is fixed on one side of the through frame, and a through groove is opened through the surface of the connecting cover, and a discharge hopper for convenient material discharge is embedded and installed directly below the connecting cover, and the through frame is fixedly installed with threads on the output end of the synchronous cylinder.

[0013] By adopting the above technical solution, synchronous drive adjustment is achieved through the provision of a synchronous cylinder.

[0014] Preferably, a mounting frame is fixedly installed on the outer side of the connecting cover, and a spray ring is fixedly installed on the inner side of the mounting frame. At the same time, an atomizing spray head is embedded and installed on the inner side of the spray ring. The spray ring is embedded and connected with one end of the corrugated conveying pipe, and a horizontal fan is fixedly installed directly in front of the mounting frame.

[0015] By adopting the above technical solution, the water mist is blown and transported by the horizontal fan.

[0016] Preferably, a corrugated soft cover is fixedly installed in front of the connecting cover, and a through-hole plate is fixed at one end of the corrugated soft cover, and a spring rod is fixedly installed between the through-hole plate and the connecting cover.

[0021] By adopting the above technical solution, the through-hole columns are provided to guide and transport the fluid.

[0022] Preferably, the connecting cover and the lower hopper are arranged in a "kettle" structure.

[0023] By adopting the above technical solution, the connection cover is provided to achieve opening and embedding through installation.

[0024] Compared with the prior art, the invention has the following beneficial effects: the ground boring machine with dustproof structure,

[0025] (1) In this case, the dust-proof structure includes: a through frame, a slider, a connecting cover, a lower hopper, a corrugated soft cover, a through-hole plate and a spring rod, thereby solving the problem that the existing tunnel boring machine drill bit is prone to generate coal dust during the construction process, which is harmful to the operator. When the ground tunnel boring machine body needs to dig into the rock or the mine, the operator drives the connecting cover, the corrugated soft cover and the through-hole plate to contact the rock or the mine digging place through the through frame. At this time, all the dust generated during the working process of the ground tunnel boring machine body is concentrated inside the connecting cover and the corrugated soft cover to prevent the dust from spreading. The excavated rock or ore is transported to the inside of the connecting cover through the corrugated soft cover, the through-hole plate and the spring rod, and then falls to the bottom of the ground tunnel boring machine body for transportation through the lower hopper;

[0026] (2) The above-mentioned problem is solved by the following components arranged in the dustproof structure: a connection cover, a mounting frame, a spray ring, a horizontal fan and an atomizing spray head. When dust is concentrated inside the connection cover, the corrugated conveying pipe conveys the spray water inside the spray ring. At this time, the horizontal fan blows the atomized water sprayed by the atomizing spray head into the connection cover to reduce the dust. At the same time, the sprayed atomized water can also be used to spray and cool the excavation head of the ground excavation machine body simultaneously.

[0027] (3) The following problems are solved by providing the following in the tunnel boring machine structure: a first threaded barrel, a two-way handwheel threaded rod, a second threaded barrel, a concave block, a through-hole cavity and a connecting threaded block, so as to solve the problem that the parts on the overall tunnel boring machine structure are directly fixedly connected to the ground tunnel boring machine body, resulting in the inability to quickly disassemble and replace the parts on the tunnel boring machine structure when they need to be disassembled and replaced later. When it is necessary to disassemble the parts on the tunnel boring machine structure, the operator first uses a tool to disassemble and separate the through-hole cavity. Then, the operator rotates the two-way handwheel threaded rod to separate the first threaded barrel and the second threaded barrel by force. Then, the operator pulls the through-hole cavity to make the concave block and the connecting threaded block synchronously pulled and separated by force, thereby disassembling and separating the parts on the overall tunnel boring machine structure from the ground tunnel boring machine body.

[0028] (4) The hollow block and the cleaning brush provided in the tunnel boring machine structure can solve the problem of soil easily adhering to the surface of the tunnel boring machine head on the ground. When the tunnel boring machine head moves inside the hollow block, the tunnel boring machine body controls the tunnel boring machine head to rotate relative to the cleaning brush. When the two rotate relative to each other, the cleaning brush performs a rotational cleaning process on the tunnel boring machine head. By performing a rotational cleaning process on the tunnel boring machine head, the tunnel boring machine head is kept clean. BRIEF DESCRIPTION OF THE DRAWINGS
