The bottom end of the filter screen plate 910 is slidably connected to a fixed seat 911; a fixing strip 912 is welded at the bottom of the fixing seat 911, and the collection box 4 is connected to the protective box 1 through a support platform. A fixing groove corresponding to the fixing strip 912 is provided at the bottom end of the inner wall of the collecting box 4, and a spring 913 is connected to one side of the outer wall of the filter screen plate 910; an elastic telescopic mechanism is formed between the filter screen plate 910, the fixing seat 911, the spring 913 and the guide seat 908, and the fixing seat 911 and the guide seat 908 are parallel to each other; the fixing seat 911 is in a "C" shape, and the pulley 907 and the filter screen plate 910 are in a rolling connection; the second synchronous wheel 904 is connected to the synchronous belt 903 inside, and the first synchronous wheel 902 is symmetrically distributed about the vertical center line of the front wheel 8, and a handle is connected to the middle of the top of the guide seat 908.

[0021] In specific implementation, when the dust generated by mining is removed by the dust removal device, as the use time increases, when the filter plate 910 is blocked, because the front wheel 8 is connected to the transmission rod 901, when the staff pushes the base 6 to move, the front wheel 8 will drive the transmission rod 901 to rotate together, and then the transmission rod 901 rotates to drive the first synchronous wheel 902 to rotate, and because the first synchronous wheel 902 is connected to the second synchronous wheel 904 through the synchronous belt 903, the rotation of the first synchronous wheel 902 will drive the second synchronous wheel 904 to rotate together, and then the second synchronous wheel 904 rotates to drive the rotating column 905 to rotate, and because the rotating column 905 is connected to the transmission plate 906, the rotation of the rotating column 905 will drive the transmission plate 906 to rotate together, and the rotation of the transmission plate 906 drives the pulley 907 to rotate;

[0022] When the pulley 907 contacts the filter screen plate 910, it will generate a thrust on the filter screen plate 910, so that the filter screen plate 910 moves along the guide seat 908 and the fixed seat 911, and the movement of the filter screen plate 910 will squeeze the spring 913 to cause it to deform, and then as the pulley 907 rotates and disconnects from the filter screen plate 910, the spring 913 will reset and generate elastic force, thereby causing the filter screen plate 910 to collide with the guide seat 908 and the fixed seat 911, and then the impurities that cause the filter screen plate 910 to be blocked will be shaken off, preventing them from blocking the filter screen plate 910 and causing the filtering effect to decrease, and there is no need to frequently remove the filter screen plate 910 for cleaning, and the cleaning work of the filter screen plate 910 can be completed during the movement of the dust removal device, thereby saving time and improving work efficiency, so that when the dust removal device for mining is used, it is convenient to clean the filter screen and improve work efficiency;

[0023] When it is necessary to clean the impurities in the collection box 4, it is only necessary to move the guide seat 908 upward to drive the filter screen plate 910 upward until the filter screen plate 910 is moved out of the collection box 4, and the inside of the collection box 4 and the filter screen plate 910 can be cleaned; when the filter screen plate 910 and the collection box 4 are cleaned, because the guide seat 908 is connected to the limiting plate 909, and the fixing seat 911 is connected to the fixing bar 912, the filter screen plate 910 is moved down into the collection box 4 until the fixing bar 912 is inserted into the collection box 4, and the limiting plate 909 is inserted into the top of the protective box 1, and then the filter screen plate 910 is limited and installed back to its original position.

[0024] To sum up, when the dust removal device for mining is used, the base 6 is first moved to the specified position by the front wheels 8 and the rear wheels 7, and then the exhaust fan 2 on the protective box 1 is started. The exhaust fan 2 extracts the air in the mining tunnel through the air inlet 3, and the extracted air enters the collection box 4 and contacts the filter screen, thereby filtering the dust particles in the air. Then the filtered dust particles are discharged into the water storage tank 5 through the conveying pipe for purification, thereby reducing the dust concentration in the mining area. This is the prior art and will not be elaborated on here. The auxiliary mechanism 9 makes the filter plate 910 collide with the guide seat 908 and the fixed seat 911, thereby shaking off the impurities that cause the filter plate 910 to be blocked, preventing them from clogging the filter plate 910 and causing the filtering effect to decrease. Then, there is no need to frequently remove the filter plate 910 for cleaning. The cleaning work of the filter plate 910 can be completed during the movement of the dust removal device, thereby saving time and improving work efficiency. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
