Description

Technical Field

[0001] The present application relates to the technical field of coal mining, and in particular to a drilling-type full-wind-pressure ventilation strip-type coal mining device. Background Art

[0002] Coal mining sites produce a variety of harmful substances, including highly toxic, explosive and even asphyxiating gases. Ventilation can dilute the concentration of these harmful gases, provide more fresh air for the mine, and ensure the safety of miners. Therefore, attention should be paid to ventilation during coal mining.

[0003] Application No. 202021961840.1 discloses a drilled full-pressure ventilation strip-type coal mining device, including a downwind door and an adjusting wind window, ventilation eyes and a return air lane, etc. The working face is arranged according to the strip-type branch lane. After the working face is formed, no local fan is required for ventilation during the mining process, but the ventilation system of the entire mine is relied on to achieve effective full-pressure ventilation; there is no problem of ventilation failure when the dual power supplies and dual fans cannot be turned on for some reason when using local ventilation; full-pressure ventilation is achieved in strip-type branch lane coal mining, eliminating the risks and safety hazards brought by the use of local fans for ventilation to implement mining operations, achieving safe ventilation and ensuring safe production.

[0004] However, in use, there are the following defects:

[0005] Although the use of local fans to ventilate the excavation operation is prohibited to achieve safe ventilation, the outside gas generated during the excavation process will first float in the mine and then be discharged by the ventilation system. In this process, the dangerous gas may cause harm to the workers and affect the safety of mine operations. Utility Model Content

[0006] The purpose of the present application is to provide a drilling-type full-wind-pressure ventilation strip-type coal mining device, which solves the problem proposed in the background technology that although the use of local fans to ventilate the excavation operation is eliminated to achieve safe ventilation, the external gas generated during the excavation process will first drift in the mine and then be discharged by the ventilation system. In this process, the dangerous gas may cause harm to the workers and affect the safety of mine operations.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a drilling-type full-pressure ventilation strip-type coal mining device, comprising an outer frame, a coal transport strip, an exhaust fan, a telescopic hose, a storage groove and a strip, the left side wall of the outer frame is connected with a connecting pipe, a drill bit is fixedly installed on the left side of the connecting pipe, an exhaust fan is embedded in the right side wall of the outer frame, and an exhaust pipe is fixedly installed on the left end of the exhaust fan, fixed magnets are embedded in the side walls of the outer frame above and below the exhaust fan, a support frame is fixedly welded above the right side wall of the outer frame, a storage frame is fixedly connected to the bottom of the support frame, and storage grooves are provided on the edges of the left and right openings of the storage frame.

[0008] In this technical solution, the drill bit is started and the working surface is rotated to collect the coal blocks, which eventually reach the coal transport belt along the connecting pipe and the transmission crawler. The exhaust pipe is facing the connecting pipe. After the exhaust fan is started, it will exhaust air from the connecting pipe, thereby directly extracting the dangerous gas. The filter will intercept the coal block residue in the air. The dangerous gas can be directly discharged through the fixed magnet, fixed frame, telescopic hose and movable magnet. The fixed frame at one end of the telescopic hose is fitted with the right side wall of the outer frame. At this time, the fixed magnet and the movable magnet are adsorbed together, and then the fixed frame at the other end of the telescopic hose is adsorbed on the vent of the main ventilation duct. In this way, The dangerous gas during coal mining can be directly extracted and will not float into the mine, thereby improving the efficiency of ventilation. When moving during coal mining, the fixed frame can be directly pulled down from the main ventilation duct, so installation and disassembly are relatively convenient. At the same time, the telescopic hose and the fixed frame can be stored through the storage frame, the storage groove and the iron block. The telescopic hose can be compressed so that the fixed frames at both ends are located in the storage groove. At this time, the movable magnets on the side walls of the fixed frame can be adsorbed together with the iron blocks in the storage groove, thereby completing the storage. When the hose is needed, it is only necessary to pull the fixed frame out of the storage groove. The operation is relatively convenient, reduces space occupancy, and improves the operating efficiency of the device.

[0009] As an optional solution of the technical solution of the present application, both ends of the telescopic hose are fixedly connected to a fixing frame.

[0010] As an optional solution of the technical solution of the present application, a plurality of iron blocks are fixedly welded on the inner surface of the storage groove in a circular array.

[0011] As an optional solution of the technical solution of the present application, a filter screen is detachably installed on the inner side of the exhaust duct.

[0012] As an optional solution of the technical solution of the present application, a transmission crawler is fixedly installed on the inner side of the outer frame below the exhaust pipe, and a coal transport belt is opened below the outer frame.

[0013] As an optional solution of the technical solution of the present application, movable magnets are embedded and installed on the side wall surfaces at both ends of the fixed frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can directly extract dangerous gases through fixed magnets, fixed frames, telescopic hoses and movable magnets. The fixed frame at one end of the telescopic hose is fitted with the right side wall of the outer frame. At this time, the fixed magnet and the movable magnet will be adsorbed together. The fixed frame at the other end of the telescopic hose is then adsorbed on the vent of the main ventilation duct. In this way, the dangerous gases during coal mining can be directly extracted and will not float into the mine, thereby improving the efficiency of ventilation.

[0016] 2. The present application can store the telescopic hose and the fixed frame through the storage frame, the storage groove and the iron block. The telescopic hose can be compressed so that the fixed frames at both ends are located in the storage groove. At this time, the movable magnets on the side walls of the fixed frame can be adsorbed together with the iron block in the storage groove, thereby completing the storage. When the hose is needed, it is only necessary to pull the fixed frame out of the storage groove. The operation is relatively convenient, reduces space occupancy, and improves the operating efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 As shown, a conveying crawler 4 is fixedly installed on the inner side of the outer frame 2 below the exhaust pipe 6, a coal transport belt 5 is opened at the bottom of the outer frame 2, and fixed magnets 9 are embedded and installed on the side walls of the outer frame 2 above and below the exhaust fan 8. A support frame 10 is fixedly welded above the right side wall of the outer frame 2, and the fixed magnets 9 can adsorb and fix the fixed frame 13.

[0025] like Figure 2 As shown, a storage frame 11 is fixedly connected to the bottom of the support frame 10, and storage grooves 15 are provided on the edges of the left and right openings of the storage frame 11. A plurality of iron blocks 16 are fixedly welded on the inner surface of the storage grooves 15 in a circular array.

[0026] In actual use, the drill bit 1 is started, the working surface is rotated, the coal blocks are collected, and finally reach the coal transport belt 5 along the connecting pipe 3 and the transmission crawler 4. The exhaust pipe 6 is opposite to the connecting pipe 3. After the exhaust fan 8 is started, it will exhaust the air at the connecting pipe 3, so as to directly extract the dangerous gas.
