[0002] Mining refers to the process of mining and extracting mineral resources. Mining plays an important role in the effective utilization of resources and economic development, but it may also bring environmental and social challenges, so scientific management and compliant operations are required.

[0003] Ventilation equipment plays a vital role in mining operations. Good ventilation provides sufficient fresh air for underground workers, removes harmful gases, dust, and heat, and ensures a safe and comfortable underground environment, thereby improving work efficiency and protecting personnel health.

[0004] However, existing mining ventilation equipment has some shortcomings: on the one hand, the filtering effect of many ventilation equipment is not ideal, and its fan may absorb dust due to long-term use. In a closed and humid environment for a long time, the dust may absorb mold due to humidity, affecting the ventilation volume. At the same time, when continuing to inhale air, the air will simultaneously blow the mold into the mine, thereby affecting the health of the workers. On the other hand, traditional ventilation equipment can often only achieve single-directional or local ventilation, and it is difficult to ensure that the entire mine space can be fully ventilated. Therefore, a mining ventilation equipment is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a ventilation equipment for mining, which aims to improve the problem in the existing technology that dust may absorb mold due to moisture, affecting the ventilation volume, and when the air continues to be inhaled, the air will simultaneously blow the mold into the mine, thereby affecting the health of the workers.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment of a ventilation device for mining, including a shell 1. The shell 1 is a ventilation duct in the prior art, a fan is provided inside it, a reciprocating mechanism 2 is provided at the top of the outer wall of the shell 1, and a filter plate 5 is detachably installed on the top of the left side of the shell 1. The filter plate 5 is a prior art. By providing the filter plate 5, dust in the air sucked into the mine can be isolated to avoid excessive dust. When the dust is sucked into the mine, the air can avoid causing discomfort. At the same time, an empty slot is provided at the top of the shell 1 to fit the filter plate 5, so that the filter plate 5 as a whole can only be taken out upward from the inner wall of the shell 1, and a counterweight block is provided at the top of the filter plate 5, which uses its own weight to keep the filter plate 5 always installed on the inner wall of the shell 1.

[0033] Reference Figure 1 and Figure 2 The outer side wall of the shell 1 is provided with a cleaning component 4, which includes a motor a41, which is fixedly connected to the inner wall of the shell 1, and a turntable a42 is rotatably connected to the outer side wall of the shell 1. The output shaft of the motor a41 is fixedly connected to the turntable a42, and the outer arc surface of the turntable a42 is hinged with a connecting rod 43. The turntable a42 can be rotated by the drive of the motor a41, so that the connecting rod 43 can reciprocate on the outer arc surface of the turntable a42, thereby driving the corresponding slider 44 to move back and forth. The end of the connecting rod 43 away from the turntable a42 is hinged with a slider 44, and a guide groove is provided on the outer side wall of the shell 1. The slider 44 is slidably connected to the inner wall of the guide groove, and is moved by the side wall of the shell 1 A guide groove is provided to fit the slider 44 so that the slider 44 can only move laterally and cannot separate from its inner wall. The upper and lower sides of the slider 44 are hinged with hinged rods 45, and the two sets of hinged rods 45 are hinged with brushes 46 at one end away from the slider 44. When the slider 44 moves back and forth following the connecting rod 43, the upper and lower sets of hinged rods 45 hinged on its outer side will synchronously pull the corresponding brushes 46 towards and away from each other on the inner wall of the shell 1, so that the dust attached to the surface of the filter plate 5 can be fully cleaned to prevent the dust from condensing at the filter holes of the filter plate 5 along with the cold air, thereby affecting the overall ventilation. The brush 46 is slidably connected to the inner wall of the front end of the shell 1, and the brush 46 is in contact with the surface of the filter plate 5.

[0034] Reference Figure 3 - Figure 4The reciprocating mechanism 2 includes a turntable b21, the outer arc surface of the turntable b21 is fixedly connected to a protrusion 22, the outer wall of the protrusion 22 is slidably connected to a guide seat 23, and the inner wall of the guide seat 23 is provided with a guide groove, so that when the protrusion 22 rotates around the center of the circle following the turntable b21, it will slide on the inner wall of the guide groove of the guide seat 23, thereby allowing the guide seat 23 to swing back and forth around its rotation center point, thereby driving the shell 1 to shake as a whole, so that it can fully ventilate the mine. The guide seat 23 is hinged at the bottom end of the outer wall of the mounting plate 3. The end of the guide seat 23 away from the mounting plate 3 is fixedly connected to the top of the outer wall of the shell 1. The top of the outer wall of the turntable b21 is rotatably connected to the mounting plate 3. Four groups of mounting holes are opened on the surface of the mounting plate 3. It can be installed at the top of the mine through the mounting holes to ventilate the mine. The inner wall of the mounting plate 3 is fixedly connected to the motor b24. The motor b24 is fixedly connected to the top of the inner wall of the mounting plate 3. The output shaft of the motor b24 is fixedly connected to the rotation center axis of the turntable b21. The turntable b21 can be driven to rotate by the motor b24.

[0035] Working principle: When using the ventilation equipment during mining, first install the equipment on the top of the mine through the four sets of mounting holes on the mounting plate 3. When the ventilation equipment is running, the outside air flows into the mine under the action of the fan, and enters the mine after filtering the dust through the filter plate 5.

[0036] When the dust accumulates to a certain extent on the filter plate 5, the motor a41 of the cleaning assembly 4 is started, and the motor a41 drives the turntable a42 to rotate. During the rotation of the turntable a42, the connecting rod 43 reciprocates on the outer arc surface of the turntable a42. The rotation of the connecting rod 43 drives the slider 44 to reciprocate in the guide groove of the outer side wall of the shell 1. When the slider 44 moves, the hinged rod 45 hinged on its upper and lower sides will move synchronously with the movement of the slider 44. Since the other end of the hinged rod 45 is hinged with a brush 46, and the brush 46 is slidably connected to the inner wall of the front end of the shell 1, during the reciprocating movement of the slider 44, the upper and lower sets of hinged rods 45 will pull the corresponding brushes 46 to move closer to and away from each other on the inner wall of the shell 1, and fully clean the dust attached to the surface of the filter plate 5. This can prevent dust from condensing at the filter holes of the filter plate 5 along with the cold air, and prevent the filter holes from being blocked and affecting the overall ventilation.

[0037] At the same time, the motor b24 drives the turntable b21 of the reciprocating mechanism 2 to rotate. The motor b24 drives the turntable b21 to rotate. When the turntable b21 rotates, the protrusion 22 on the outer arc surface of its surface rotates around the center of the circle. Since the outer wall of the protrusion 22 is slidingly connected to the guide groove of the guide seat 23, the protrusion 22 will slide on the inner wall of the guide groove of the guide seat 23 during the rotation process, so that the guide seat 23 swings back and forth around its rotation center point. The reciprocating swing of the guide seat 23 drives the shell 1 to shake as a whole. This shaking enables the ventilation equipment to fully ventilate the mine, so that the air in different areas of the mine can be effectively updated, thereby improving the air quality environment in the mine.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
