Description

Technical Field

[0001] This utility model relates to the field of coal gangue processing technology, specifically a coal gangue crushing and screening device. Background Technology

[0002] Coal gangue is a solid waste generated during coal mining and washing. The large accumulation of coal gangue not only occupies land resources, but may also cause environmental problems such as spontaneous combustion, dust, and water pollution. Therefore, the comprehensive utilization of coal gangue resources has become an industry consensus. Efficient screening is a key pretreatment step in the deep processing of coal gangue. Therefore, the development of a coal gangue crushing and screening device has important practical significance.

[0003] According to CN218393957U, a coal gangue crushing and screening device includes a support frame with a support plate fixed to it. The support plate extends downward at an incline. A first bearing assembly, a second bearing assembly, and a third bearing assembly are disposed at the upper end of the support plate, and a rotating rod passes through each of the bearing assemblies. A screen cylinder is obliquely disposed between the first and second bearing assemblies. The rotating rod is connected to the screen cylinder via several sets of connecting rods, each set of connecting rods having multiple protruding teeth. Multiple screen holes are evenly distributed on the screen cylinder. A crushing box is inclinedly arranged between the second and third bearing assemblies. The crushing box is fixed to the support plate by two sets of pads. A rotating rod is connected to several sets of crushing blades inside the crushing box. A drive motor is installed on the lower side of the support plate. This device effectively screens out the larger parts of the coal gangue fragments and crushes the larger coal gangue fragments twice, improving the quality of the brick products. As can be seen from the above, although this device can be applied well, it usually relies on multiple crushing blades to crush the coal gangue, making it difficult for the device to achieve the expected crushing effect on coal gangue, and further improvement is needed.

The input end of the second servo motor 19 is electrically connected to the output end of the microcontroller inside the control panel 2. One end of the second servo motor 19 is connected to one end of a conveyor roller 23.

[0026] In use, the second servo motor 19 is configured to drive a conveyor roller 23 to rotate;

[0027] Support plates 9 are provided on the outer wall of the upper end of the second support frame 4. A base plate 10 is fixed at the top of the support plate 9. A scrap box 11 is provided at the top of the base plate 10. The bottom end of the scrap box 11 extends to the bottom of the base plate 10. A first servo motor 13 is installed at the top of the base plate 10 on one side of the scrap box 11.
