[0002] Before mining, the mine must first be excavated by machines to find the location of the mine. After the large mine is excavated, construction workers are usually required to use handheld pneumatic picks and other equipment to excavate the cave walls when looking for ore. During the excavation process, a large amount of dust will be generated when pneumatic picks and other equipment dig the mine walls. If this dust is not dealt with in time, it will not only affect the line of sight and make the excavation inaccurate, but also cause great harm to the human body and increase the chance of pneumoconiosis. The existing technology usually uses watering to deal with this dust, which not only wastes water resources, but also dilutes the soil in the mine, which is not conducive to progress.

[0019] Example 1

[0020] The dust removal mechanical device for mining and rock drilling equipment described in this embodiment is as follows: Figure 1 and Figure 4 As shown, it includes a ring 1, and a locking assembly is arranged inside the ring 1, which is convenient for installation on the excavation equipment. The excavation equipment is an existing handheld pneumatic pick. When in use, the ring 1 is sleeved on the pneumatic pick and then fixed by the locking assembly;

[0021] The front side wall of the ring 1 is provided with an annular groove, in which a dust collecting component is arranged, so as to timely absorb the dust generated during excavation, reduce the influence of dust on the construction workers and the influence on their vision during excavation, and make the excavation more accurate;

[0022] The dust collection assembly includes an exhaust fan 4, a ventilation hole is opened at the bottom of the annular groove, and a dust filter is installed at the notch of the annular groove, so as to facilitate the absorption of dust into the annular groove and filter absorption at the same time, so as to avoid excessive dust from entering the exhaust fan 4 and causing damage;

[0023] The outer wall of the ring 1 is provided with a blocking component for blocking flying dust, which is convenient for blocking dust that is not adsorbed in time, preventing the dust from being directly inhaled into the human body, and is also convenient for blocking the dust to reduce the flow speed, thereby improving the dust removal effect;

[0024] The ring 1 is a circular plate structure, which is convenient for setting the locking assembly and opening the annular groove.

[0025] The locking assembly comprises two clamping blocks 5 which are clamped and matched up and down, and the outer ends of the clamping blocks 5 are vertically provided with adjusting rods 6 which can rotate freely left and right with the clamping blocks 5. The circular ring 1 is provided with threaded through holes for threadedly matching with the adjusting rods 6, and the movable ends of the adjusting rods 6 are provided with "cross" grooves, so that the adjusting rods 6 can be driven to rotate by a screwdriver, thereby clamping the clamping blocks 5 on the pneumatic pick machine;

[0026] The clamping surface of the clamp block 5 is provided with an arc groove to improve the fit with the pneumatic pick, thereby improving the fixing effect;

[0027] The adjusting rod 6 and the clamping block 5 are connected via a bearing, so that the position of the clamping block 5 remains unchanged when the adjusting rod 6 rotates.

[0028] The dust filter includes a first filter 7 and a second filter 8, and the mesh number of the first filter 7 is smaller than that of the second filter 8, so as to facilitate layered filtering, avoid clogging caused by excessive filtration of a single layer of filter, and further reduce the dust removal effect while reducing the impact of dust on the exhaust fan 4, thereby increasing its service life and reducing the cost of use;

[0029] The adjusting rod 6 is located between the first filter screen 7 and the second filter screen 8 .

[0030] like Figure 1 and Figure 2 As shown, the blocking assembly includes a plurality of blocks 2, and the blocks 2 all move in a circle along the outer wall of the ring 1, and baffles 3 are provided inside the blocks 2 to slide with the ring 1. When the baffles 3 are fully unfolded, the blocks 2 and the baffles 3 form a circular ring structure, which is convenient for blocking dust and adjusting the shielding area according to needs, so as to facilitate construction workers to carry out construction under safety, thereby improving applicability;

[0031] The blocking assembly may further include a second blocking block of an annular structure, and the second blocking blocks of different sizes can be replaced as needed during use;

[0032] The block 2 and the baffle 3 are both fixed to the ring 1 by screws. When in use, after adjusting the blocking positions of the block 2 and the baffle 3, they are fixed by screws to block dust.

[0035] This embodiment further illustrates the technology. Figure 3 As shown, the front side wall of the ring 1 is provided with a plurality of countersunk holes except the annular groove area, and the bottom of the countersunk holes is located in the area between the bottom of the exhaust fan 4 and the bottom of the annular groove, and the inner side wall of the annular groove is provided with a second through hole connected to the countersunk hole, so that the gas sucked in by the exhaust fan 4 is discharged toward the front side of the ring 1 through the second through hole and the countersunk hole, thereby facilitating to avoid the gas exhausted by the exhaust fan 4 facing the face of the construction workers, thereby facilitating to further reduce the impact of dust on the construction workers, and also facilitating to improve the dust removal effect, and also facilitating to blow away the dust at the excavation site by the exhausted wind, so that the construction workers have a clearer vision.

[0036] The bottom of the annular groove is provided with a guide block 9 for guiding the airflow direction, and the guide block 9 is a hemispherical structure as a whole, which is convenient for guiding the gas sucked by the exhaust fan 4 into the second through holes on both sides, so as to facilitate rapid discharge.

[0037] Working principle: first put the ring 1 on the pneumatic pick, and then clamp the clamp 5 on the pneumatic pick. Before excavation, first adjust the shielding area of ​​the block 2 and the baffle 3, then start the exhaust fan 4, and then start drilling. The exhaust fan 4 sucks the dust generated during the rock drilling process into the annular groove, and filters it in layers through the first filter screen 7 and the second filter screen 8, and then discharges it in the excavation direction through the second through hole and the countersunk hole.
