[0001] This invention belongs to the field of coal mining technology, specifically relating to a material sorting mechanism for a coal mining machine. Background Technology

[0003] Although the existing coal mining machine material sorting mechanism can screen and classify coal slag, it cannot fully stir-fry the coal slag during screening, resulting in the inability to effectively carry out step-by-step screening of the coal slag; although the material sorting mechanism can move, the stability of the device during the sorting process is relatively poor after it moves to the designated position. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please refer to Figures 1-5. The present invention provides the following technical solution: a material sorting mechanism for a coal mining machine, including a base 1, a movable wheel 9 at the lower corner of the base 1, a sorting box 2 at the upper end of the base 1, a feed hopper 3 at the upper end of the sorting box 2, a primary screen plate 10 at the upper end of the sorting box 2, a secondary screen plate 11 at the center of the sorting box 2, a tertiary screen plate 12 at the lower end of the sorting box 2, multiple sets of baffles 6 on the side of the sorting box 2, all sets of baffles 6 being rotatably connected to the sorting box 2 via a rotating shaft 5, a handle 7 at the lower end of the side of the baffle 6, a support lifting mechanism 8 on the side of the base 1, and a coal slag step-by-step screening mechanism 4 at the lower end of the side of the sorting box 2.

[0026] Specifically, the slag step-by-step screening mechanism 4 includes a slag stirring component 41, an L-shaped fixing plate 42, a hinge seat 43, a hydraulic rod 44, a rotating shaft 45, a U-shaped seat 46, and a second hinge seat 47. A U-shaped seat 46 is provided on the upper side of the base 1. The sorting box 2 is rotatably connected to the U-shaped seat 46 via the second rotating shaft 45. A second hinge seat 47 is provided at the upper corner of the base 1. A hydraulic rod 44 is provided at the upper end of the second hinge seat 47. A hinge seat 43 is provided at the upper end of the hydraulic rod 44. An L-shaped fixing plate 42 is provided at the upper end of the first hinge seat 43 and is fixedly connected to the sorting box 2 with screws. The slag stirring component 41 is provided inside the sorting box 2.

[0027] By adopting the above technical solution, coal slag is poured into the sorting box 2 through the feed hopper 3. The coal slag can be screened by the first-stage screen plate 10, the second-stage screen plate 11 and the third-stage screen plate 12. After screening, the hydraulic rod 44 is opened. After the hydraulic rod 44 is extended, it will drive the sorting box 2 to rotate through the rotating shaft 45 and the U-shaped seat 46, so that the coal slag can slide smoothly from the opening at the baffle 6. At the same time, a loading box is placed at each set of baffles 6 to load the screened coal slag.

[0028] Specifically, both the upper and lower ends of the hydraulic rod 44 are rotatably connected to hinge seat 2 47 and hinge seat 1 43 via pins.

[0029] By adopting the above technical solution, the structure can avoid the problem of the hydraulic rod 44 getting stuck during rotation.

[0030] Specifically, the coal slag stirring assembly 41 includes a rotating shaft 3 411, a gear 412, a flexible toothed belt 2 413, a gear 3 414, a gear 2 415, a flexible toothed belt 1 416, a gear 1 417, a stirring rod 418, a motor 1 419, a rotating shaft 1 4110, and a rotating shaft 2 4111. The upper side of the sorting box 2 is equipped with a motor 1 419, and the output end of the motor 1 419 is equipped with a rotating shaft 1 4110. The other end of the rotating shaft 1 4110 is equipped with a gear 1 417, and the outer surface of the gear 1 417 is meshed with a flexible toothed belt 1 416. A gear 415 is meshed with the inner surface of the other end of a flexible toothed belt 416. A rotating shaft 4111 is fixedly installed through the inside of the gear 415. A gear 414 is installed at one end of the rotating shaft 4111. A flexible toothed belt 413 is meshed with the outer surface of the gear 414. A gear 412 is meshed with the inner surface of the other end of the flexible toothed belt 413. A rotating shaft 411 is installed on the side of the gear 412. A stirring rod 418 is installed on the surfaces of the rotating shaft 411, the rotating shaft 4110, and the rotating shaft 4111.

[0031] By adopting the above technical solution, when motor 1 419 is turned on, motor 1 419 drives rotating shaft 1 4110 to rotate through its output end. Rotating shaft 1 4110 drives gear 1 417 to rotate. Gear 1 417 drives flexible toothed belt 1 416 to rotate. Flexible toothed belt 1 416 drives gear 2 415 to rotate. Gear 2 415 drives rotating shaft 2 4111 to rotate. Rotating shaft 2 4111 drives gear 3 414 to rotate. Gear 3 414 drives flexible toothed belt 2 413 to rotate. Flexible toothed belt 2 413 drives gear 412 to rotate. Gear 412 drives rotating shaft 3 411 to rotate. The rotation of rotating shaft 1 4110, rotating shaft 2 4111, and rotating shaft 3 411 drives stirring rod 418 to rotate, thereby stirring the coal slag on the upper part of the screen plate and preventing the coal slag from clogging the screen plate and causing the problem of not being able to screen smoothly.

[0032] Specifically, the other ends of both rotating shaft 3 411 and rotating shaft 2 4111 are rotatably connected to the inner wall of sorting box 2 via bearings.

[0033] By adopting the above technical solution, the structure can avoid the problem of rotational jamming of rotating shaft 2 4111 and rotating shaft 3 411.

[0034] In this embodiment, coal slag is poured into the sorting box 2 through the feed hopper 3. The coal slag is then screened using the primary screen 10, secondary screen 11, and tertiary screen 12. After screening, the hydraulic rod 44 is opened, extending to rotate the sorting box 2 via the rotating shaft 45 and U-shaped seat 46. This allows the coal slag to slide smoothly from the opening at the baffle 6. Simultaneously, a loading box is placed at each baffle 6 to load the screened coal slag. The motor 419 is then turned on, driving the rotating shaft 4110 through its output end. The rotating shaft 4110 then drives the gear 417 to rotate. The movement drives the flexible toothed belt 416 to rotate, which in turn drives the gear 415 to rotate. The gear 415 then drives the rotating shaft 4111 to rotate, which in turn drives the gear 414 to rotate. The gear 414 then drives the flexible toothed belt 413 to rotate, which in turn drives the gear 412 to rotate. The gear 412 then drives the rotating shaft 411 to rotate. The rotation of the rotating shafts 4110, 4111, and 4111 drives the stirring rod 418 to rotate, thereby stirring the coal slag on the upper part of the screen plate and preventing the coal slag from clogging the screen plate and causing problems with smooth screening.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that the support lifting mechanism 8 includes a support base 81, a lifting plate 82, a threaded rod 85, a second bevel gear 86, a first bevel gear 87, a rotating rod 88, and a second motor 89. The second motor 89 is located on the side of the base 1. The output end of the second motor 89 is connected to the rotating rod 88. The other end of the rotating rod 88 is connected to the first bevel gear 87. The side of the first bevel gear 87 is meshed with the second bevel gear 86. A threaded rod 85 is fixedly installed through the interior of the second bevel gear 86. The surface of the threaded rod 85 is threadedly connected to the lifting plate 82. The lower side of the lifting plate 82 is provided with the support base 81.

[0037] By adopting the above technical solution, after the device is moved to the designated position, motor 2 89 is turned on. Motor 2 89 drives the rotating rod 88 to rotate through the output end. The rotation of the rotating rod 88 drives the bevel gear 1 87 to rotate. The rotation of the bevel gear 1 87 drives the bevel gear 2 86 to rotate. The rotation of the bevel gear 2 86 drives the threaded rod 85 to rotate. The rotation of the threaded rod 85 drives the lifting plate 82 to descend. The descent of the lifting plate 82 drives the support base 81 to descend until it contacts the ground, thereby increasing the contact area between the base 1 and the ground, thus ensuring the stability of the device during use.

[0038] Specifically, the support lifting mechanism 8 also includes a slider 83 and a groove 84. The slider 83 is provided on the side of the lifting plate 82, and the groove 84 corresponding to the slider 83 is opened on the inner wall of the base 1.

[0039] By adopting the above technical solution, when the lifting plate 82 is raised or lowered, it will drive the slider 83 to slide inside the slide groove 84, thereby improving the stability of the lifting plate 82 during the lifting process.

[0040] Specifically, the lower end of the support base 81 is provided with anti-slip texture, and the inside of the lifting plate 82 is provided with threaded holes corresponding to the threaded rod 85. Both ends of the threaded rod 85 are rotatably connected to the base 1 through bearings.

[0041] By adopting the above technical solution, the structure can avoid the problem of the threaded rod 85 getting stuck during rotation.

[0042] In this embodiment, after moving the device to the designated position, motor 2 89 is turned on. Motor 2 89 drives the rotating rod 88 to rotate through its output end. The rotation of the rotating rod 88 drives the first bevel gear 87 to rotate. The rotation of the first bevel gear 87 drives the second bevel gear 86 to rotate. The rotation of the second bevel gear 86 drives the threaded rod 85 to rotate. The rotation of the threaded rod 85 drives the lifting plate 82 to descend. The descent of the lifting plate 82 drives the support base 81 to descend until it contacts the ground, thereby increasing the contact area between the base 1 and the ground, thus ensuring the stability of the device during use. When the lifting plate 82 rises and falls, it drives the slider 83 to slide inside the slide groove 84, thereby improving the stability of the lifting plate 82 during the lifting process.

[0043] Working principle and usage process of this invention: In use, coal slag is poured into the sorting box 2 through the feed hopper 3. The coal slag is then screened through the primary screen plate 10, secondary screen plate 11, and tertiary screen plate 12. After screening, the hydraulic rod 44 is opened, extending and causing the sorting box 2 to rotate via the rotating shaft 45 and U-shaped seat 46. This allows the coal slag to smoothly slide down from the opening at the baffle 6. Simultaneously, a loading box is placed at each set of baffles 6 to further process the screened coal slag. Slag is loaded, and motor 419 is turned on. Motor 419 drives rotating shaft 4110 to rotate via its output end. Rotating shaft 4110 drives gear 417 to rotate. Gear 417 drives flexible toothed belt 416 to rotate. Flexible toothed belt 416 drives gear 415 to rotate. Gear 415 drives rotating shaft 4111 to rotate. Rotating shaft 4111 drives gear 414 to rotate. Gear 414 drives flexible toothed belt 4111 to rotate. The rotation of the flexible toothed belt 413 drives the rotation of gear 412, which in turn drives the rotation of shaft 411. The rotation of shafts 4110, 4111, and 411 drives the rotation of stirring rod 418, thereby stirring the coal slag on the upper part of the screen plate and preventing the coal slag from clogging the screen plate and causing it to be unable to be screened smoothly. After the device is moved to the designated position, motor 89 is turned on. Motor 89 drives rotating rod 88 through its output end. Rotating rod 88 drives bevel gear 87, which in turn drives bevel gear 86, which in turn drives threaded rod 85. Threaded rod 85 drives lifting plate 82 to descend. The descent of lifting plate 82 drives support base 81 to descend until it contacts the ground, thereby increasing the contact area between base 1 and the ground and ensuring the stability of the device during use. When lifting plate 82 rises and falls, it drives slider 83 to slide inside the groove 84, thereby improving the stability of lifting plate 82 during the rising and falling process.
