[0027] 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.

[0028] Reference Figure 1 - Figure 6 As shown, the utility model provides a mining machinery screen cleaning mechanism, including a mounting frame 1 and a cleaning box 2, a moving component 5 is installed in the inner cavity of the cleaning box 2, a mounting frame 6 is installed on the moving component 5, a clamping mechanism 7 is installed in the mounting frame 6, and a cleaning component 4 is installed in the middle of the inner cavity of the cleaning box 2;

[0029] Among them, the outer wall of the cleaning box 2 is installed with a control panel 3, which is connected to the electrical equipment in the device through wires and controls the operation of the electrical equipment;

[0030] The cleaning component 4 has the same cleaning principle as that of a mining machinery screen cleaning mechanism mentioned in the utility model patent publication number CN220991817U, and will not be described in detail here;

[0031] The clamping mechanism 7 includes a connecting block 701 and a plug-in block 706;

[0032] A groove 7017 is provided on the upper side wall of the connecting block 701, a through groove 704 is provided on the top surface of the inner cavity of the groove 7017, a clamping frame 705 is installed on one side of the top surface of the connecting block 701, and a plug-in block 706 is slidably installed in the through groove 704;

[0033] A plug-in plate 707 is clamped in the through slot 704. A mounting plate 7013 is mounted on the top surface of the plug-in plate 707. A plug-in rod 7014 is slidably mounted in the mounting plate 7013. A moving block 7015 is mounted on one end of the plug-in rod 7014. A second spring 7016 is sleeved on the outer wall of the plug-in rod 7014. One end of the second spring 7016 is connected to the moving block 7015. The side of the second spring 7016 away from the moving block 7015 is connected to the mounting plate 7013.

[0034] A plurality of adjustment slots 8 are evenly provided on the left and right sides of the top surface of the mounting frame 6. A placement slot 9 is provided between adjacent adjustment slots 8. A horizontal plate 10 is clamped between the placement slots 9 on the same side. A plug-in block 706 is clamped between the horizontal plate 10 and the plug-in plate 707.

[0035] Among them, a layer of rubber sleeve can be provided around the horizontal plate 10, so that when the plug-in plate 707 squeezes the plug-in block 706, the friction between the plug-in block 706 and the horizontal plate 10 is increased, thereby enhancing the integrity of the clamping mechanism 7 and the horizontal plate 10;

[0036] When the device is in use, the horizontal plate 10 will move up and down in the placement slot 9 to a certain extent, thereby enhancing the vibration of the screen.

[0037] In this embodiment, the distance between the front and rear clamping mechanisms 7 is adjusted as needed during the use of the device. During installation, the connecting block 701 is first inserted into the adjustment groove 8. At this time, the grooves 7017 of the two connecting blocks 701 on the left and right sides are located above the installation frame 6.

[0038] Then a transverse plate 10 is inserted between the two grooves 7017 on the same side, and the transverse plate 10 is snapped into the plurality of placement slots 9;

[0039] Further insert the plug-in block 706 into the through slot 704 and pull the connecting block 701 upwards so that the bottom surface of the groove 7017 contacts the horizontal plate 10;

[0040] Finally, insert the plug-in board 707 into the through slot 704 and squeeze it against the top surface of the plug-in block 706. During installation, pull the plug-in rod 7014 to drive the moving block 7015 to compress the second spring 7016. When the through slot 704 and the plug-in block 706 are in squeeze contact, release the pull on the plug-in rod 7014, and the moving block 7015 will be snapped into the snap-in frame 705 under the action of the second spring 7016.

[0041] The above operation can adjust the distance between the two clamping mechanisms 7, so that the device can position and clean installed screens of different sizes, and after installation, a horizontal plate 10 is respectively passed between the two clamping mechanisms 7 on the left and right sides to enhance their integrity.

[0042] In a further embodiment, referring to Figure 1 - Figure 6 , a mounting groove 702 is provided on the side wall of the connecting block 701, a spring 1 703 is installed on the bottom surface of the inner cavity of the mounting groove 702, and an upper splint 708 is installed on the top surface of the spring 1 703;

[0043] A positioning plate 7012 and a lower clamping plate 7010 are sequentially installed on the lower side of the connecting block 701 from top to bottom. The upper clamping plate 708 is located between the positioning plate 7012 and the lower clamping plate 7010. A bolt 709 is threadedly connected to the positioning plate 7012. The bolt 709 passes through the positioning plate 7012 and extends to the bottom of the positioning plate 7012. The upper clamping plate 708 is rotatably installed at the end of the bolt 709.

[0044] Positioning posts 7011 are symmetrically slidably mounted on the positioning plate 7012, and the bottom surfaces of the two positioning posts 7011 are connected to the upper clamping plate 708;

[0045] The positioning column 7011 is used to limit the movement direction of the upper clamping plate 708 in the numerical direction to prevent the upper clamping plate 708 from swinging;

[0046] In this embodiment, when cleaning the screen, the screen is placed between the positioning plate 7012 and the lower clamping plate 7010, and the upper clamping plate 708 is driven up and down by tightening the bolt 709 to clamp the screen between the upper clamping plate 708 and the lower clamping plate 7010, thereby achieving the clamping and positioning of the screen;

[0047] At this time, spring 1 703 always exerts a downward pulling force on the upper clamping plate 708, increasing the friction between the bolt 709 and the positioning plate 7012, reducing the possibility of the bolt 709 loosening, and making the upper clamping plate 708 and the lower clamping plate 7010 clamp the screen more stably.

[0048] In a further embodiment, referring to Figure 1 - Figure 6 The moving assembly 5 includes a motor 501. The motor 501 is installed on the outer wall of the cleaning box 2. The power output shaft of the motor 501 passes through the outer wall of the cleaning box 2 and extends to the inside of the cleaning box 2. A threaded rod 502 is installed on the power output shaft of the motor 501. A connecting column 503 is installed between the front and rear inner walls of the cleaning box 2. A moving ring 2 505 is slidably installed on the connecting column 503. Two moving rings 1 504 are threadedly connected to the threaded rod 502.

[0049] The connecting column 503 and the second movable ring 505 on the connecting column 503 are used to limit the installation frame 6 to prevent the installation frame 6 and the first movable ring 504 from rotating with the rotation of the threaded rod 502;

[0050] A mounting frame 6 is installed between the two moving rings 1 504 and the two moving rings 2 505;

[0051] In this embodiment, when cleaning the screen, the starting motor 501 drives the threaded rod 502 to rotate, thereby adjusting the positions of the two movable rings 504, and moving the screen installed through the mounting frame 6 and the clamping mechanism 7 between the two cleaning rollers in the cleaning assembly 4, thereby improving the cleaning efficiency.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
