[0002] Mining, a comprehensive energy term, is the technology and science of extracting mineral resources from the earth's crust and surface. When mining, it is usually necessary to use ventilation structures to ventilate the mine tunnels to ensure the air quality in the mine tunnels.

[0003] A Chinese patent with publication number CN220621928U discloses a ventilation structure for a continuous mining system, including a mounting shell, the rear side of the mounting shell is connected to a ventilation pipe, the top of the ventilation pipe is connected to a first motor by bolts, the bottom of the ventilation pipe is connected to a blow hood, the drive shaft of the first motor passes through the inner cavity of the ventilation pipe and is connected to a ventilation fan by bolts, a spray mechanism is provided on the surface of the mounting shell, a cleaning mechanism is provided on the front side of the surface of the mounting shell, and a filter plate is connected to the front side of the mounting shell by bolts.

[0004] Through research and analysis, it was found that although the advantages of meeting the requirements of continuous mining can be met, there are still the following disadvantages to a certain extent. For example, in order to prevent the filter plate at one end of the ventilation pipe from being blocked, an electrically controlled cleaning brush is used to clean the filter plate back and forth. However, since the spring is connected to the movable connecting plate and the brush plate through a spring seat with a large number of bolts, it is not convenient to disassemble and replace the brush plate later as it is used and the brush plate ages.

The spring push mechanism 12 is movably installed with a brush plate 14 through the connecting mechanism 15. The basic principle of the ventilation structure used in this technical solution is the same as that of a ventilation structure for a continuous mining system disclosed in publication number CN220621928U, in which two sets of screws are driven by a single motor and engaged with a chain sprocket at the lower end to simultaneously drive the two sets of screws to run synchronously, so that the lifting block 6 connected to the outer side of the screw with a thread can slide vertically up and down;

[0025] The fixing mechanism 8 includes a mounting groove 801, which is symmetrically arranged on the front side of the mounting plate 7. A first guide rod 806 is symmetrically fixedly installed on the inner side of the mounting groove 801. A first movable plate 802 is slidably connected to the outer side of the first guide rod 806. A first spring 804 is sleeved on the outer side of the first guide rod 806. A clamping block 807 is fixedly connected to the side of the first movable plate 802 away from the first spring 804. The clamping end of the clamping block 807 is clamped with the clamping groove 9. A pull rod 803 is symmetrically fixedly connected to the front side of the first movable plate 802. The pull rod 803 The other end is fixedly connected with the same pull handle 805. When disassembling the mounting plate 7, the two pull handles 805 on the front side of the mounting plate 7 are used to pull them close to each other, so that the first moving plate 802 connected by the pull handle 805 through the pull rod 803 slides on the first guide rod 806 of the mounting groove 801 and compresses the first spring 804.

The hand bolt 153 passes through the countersunk hole 16 of the brush plate 14 and the screw hole 152 of the connecting groove 151 for connection and installation. At the same time, the end of the hand bolt 153 is in the countersunk hole 16 without protruding, so it is convenient for disassembly and assembly, and it will not affect the use of the brush plate 14.

[0031] refer to Figure 4 The threaded sleeve of the hand-tightening bolt 153 is provided with a gasket 17, and the gasket 17 is arranged on the inner side of the countersunk hole 16. The gasket 17 on the hand-tightening bolt 153 can enhance the stability of the fixing of the hand-tightening bolt 153.

[0032] Principle and advantages of use: During use, when disassembling the mounting plate 7, the two pull handles 805 on the front side of the mounting plate 7 are pulled close to each other, so that the first moving plate 802 connected to the pull handle 805 through the pull rod 803 slides on the first guide rod 806 of the mounting groove 801 and compresses the first spring 804. When the clamping end of the clamping block 807 on the first moving plate 802 is separated from the clamping groove 9, the mounting plate 7 can be directly taken out from the positioning grooves 10 of the lifting blocks 6 at both ends;

[0033] On the basis of disassembling the mounting plate 7, it is only necessary to remove a hand-tightened bolt 153 at the brush plate 14, and then the brush plate 14 can be disassembled through the connecting groove 151 on the push block 122, and the brush plate 14 can be quickly disassembled and replaced.
