[0002] During the coal mining process, gangue is mined simultaneously. Previously, coal mines have always treated gangue as fixed waste or used it to fill underground goafs. With the deepening of research on the utilization of gangue, gangue can be used to make cement, bricks, paving roads, etc. Gangue, as a by-product of the coal mining process, usually exists in the form of solid blocks. In order to save storage space for gangue and facilitate subsequent processing and utilization, the gangue needs to be crushed. The existing gangue crushing device uses counter-rotating crushing rollers to crush the gangue. In a single crushing process, the gangue is mostly crushed to a single particle size. When using the existing gangue crushing device to produce gangue particles of different particle sizes, it is necessary to replace the crushing rollers or adjust the distance between adjacent crushing rollers.

[0033] Example 1:

[0034] A coal gangue crushing and sorting device, such as Figures 1-6 As shown, it includes a frame 1, the left part of the upper side of the frame 1 is connected to the feed hopper, the upper side of the frame 1 is fixed with evenly arranged columns 2, and a dividing plate 3 is slidably connected between the evenly arranged columns 2, and a control module is installed on the right part of the upper side of the frame 1. A leakage port is provided on the left side of the dividing plate 3, and the height of the dividing plate 3 gradually decreases linearly from left to right. A screening net 4 is fixed at the leakage port of the dividing plate 3, and the screening net 4 is used to screen coal gangue raw materials of different particle sizes. The upper side of the interior of the frame 1 is fixed with a feeding plate 5 arranged in a left and right mirror image and located below the dividing plate 3. The feeding plate 5 is located below the dividing plate 3, and a crushing shell 6 is fixed to the middle part of the frame 1. Two independent cavities arranged in a left and right mirror image are provided in the crushing shell 6. The two independent cavities are both connected to the outside world, and the lower sides of the independent cavities of the crushing shell 6 are rotatably connected with crushing rollers 7 arranged in a left and right mirror image. The distance between adjacent crushing rollers 7 in the left independent cavity of the crushing shell 6 is smaller than the distance between adjacent crushing rollers 7 in the right independent cavity. A cleaning shell 8 arranged in left and right mirror images is fixedly connected to the lower part of the frame 1. The cleaning shell 8 is fixed to the crushing shell 6. The front part of the upper side of the cleaning shell 8 is installed with a first motor 9 electrically connected to the control module. The cleaning shell 8 is provided with a transmission mechanism 10 for transmitting power to the adjacent and left and right mirror-arranged crushing rollers 7. The frame 1 is provided with a vibration mechanism 12 for vibrating the dividing plate 3. By dividing the coal gangue of different particle sizes into different areas and crushing them independently, it is prevented that the coal gangue of different particle sizes is prevented from being excessively or insufficiently crushed under the action of the same crushing roller 7, thereby improving the crushing effect of the coal gangue. At the same time, two different sizes of coal gangue particles are obtained in a single crushing process, thereby improving the diversity of coal gangue crushing.

[0035] like Figure 6 and Figure 7 As shown, the transmission mechanism 10 includes a transmission shaft 1001, which is rotatably connected to the adjacent cleaning shell 8 through a connecting plate. The transmission shaft 1001 and the adjacent crushing roller 7 are driven by a pulley belt. The output shaft of the first motor 9 is fixedly connected to a transmission wheel 1002. The transmission wheel 1002 is frustum-shaped, and the outer diameter of the transmission wheel 1002 gradually increases linearly from front to back. The rear end of the transmission shaft 1001 is provided with a sliding shaft 1003. The rear end of the sliding shaft 1003 is fixedly connected to a transmission disk 1004 that cooperates with the transmission disk 1004. The rear end of the crushing roller 7 is fixedly connected to a spur gear 11. The spur gear 11 is located outside the crushing shell 6, and adjacent spur gears 11 are meshed.

[0036] like Figure 3 and Figure 4As shown, the vibration mechanism 12 includes a second motor 1201 electrically connected to the control module, the second motor 1201 is installed on the right part of the lower inner side of the frame 1, an elastic member is fixed between the column 2 and the dividing plate 3, and the elastic member is a tension spring. The output shaft of the second motor 1201 is fixedly connected to the first rotating shaft 1202, and the interior of the frame 1 is rotatably connected to the second rotating shaft 1203 through the support plate. A first transmission member 1204 is provided between the first rotating shaft 1202 and the second rotating shaft 1203. The first transmission member 1204 consists of two bevel gears meshing with each other. The bevel gears are fixedly connected to the first rotating shaft 1202 and the second rotating shaft 1203 respectively, and the third rotating shaft 1205 is rotatably connected in the frame 1. The second rotating shaft 1203 and the third rotating shaft 1205 are driven by a pulley belt to transmit power to the third rotating shaft 1205. The third rotating shaft 1205 is fixedly connected with cams arranged in front and back mirror images. The cam of the third rotating shaft 1205 cooperates with the dividing plate 3. The rotating cam rotates continuously, causing the dividing plate 3 to move up and down continuously, thereby accelerating the movement speed of the coal gangue raw materials on the dividing plate 3, thereby improving the crushing efficiency.

[0037] like Figure 3 、 Figure 5 and Figure 6 As shown, it also includes a dust removal mechanism 13 arranged in a left and right mirror image, the dust removal mechanism 13 is used to remove dust, the dust removal mechanism 13 is set in the adjacent cleaning shell 8, the dust removal mechanism 13 includes a linear array of fans 1301, the fan 1301 is installed on the side of the adjacent cleaning shell 8 away from the crushing shell 6, the cleaning shell 8 is fixedly connected to the side of the crushing shell 6 with a filter 1302, the filter 1302 is used to intercept the crushed coal gangue particles, the distance between the left and right mirror image filters 1302 is less than the distance between the left and right mirror image fans 1301, the cleaning shell 8 is connected to the mirror image dust exhaust pipe 1303, the mirror image dust exhaust pipe 1303 is respectively located on the front and rear sides of the adjacent cleaning shell 8, the exhaust The dust pipe 1303 passes through the lower side of the frame 1, and the middle part of the cleaning shell 8 is rotatably connected to the reciprocating screw 1304. The transmission shaft 1001 and the adjacent reciprocating screw 1304 are driven by a pulley belt. A scraper 1305 is slidably connected in the cleaning shell 8. The scraper 1305 is threadedly engaged with the adjacent reciprocating screw 1304. The rotating reciprocating screw 1304 causes the adjacent scraper 1305 to move back and forth, thereby scraping off the dust in the adjacent cleaning shell 8. The dust generated when the coal gangue is crushed is extracted by the fan 1301, reducing the degree of dust diffusion, improving the quality of the working environment of the staff, and preventing dust from entering the crushed coal gangue product, thereby improving the quality of the crushed coal gangue particles.

[0038] When the device is needed to crush coal gangue, the staff starts the two first motors 9, the second motor 1201 and the fan 1301 through the control module. The output shafts of the two first motors 9 and the output shaft of the second motor 1201 start to rotate. The output shafts of the first motors 9 drive the adjacent transmission wheels 1002 to rotate together. The transmission wheels 1002 drive the adjacent transmission discs 1004 to rotate in the opposite direction. The transmission discs 1004 drive the adjacent sliding shafts 1003 to rotate together. The sliding shafts 1003 drive the adjacent transmission shafts 1001 to rotate together. The transmission shafts 1001 drive the adjacent transmission shafts 1001 through the pulley belt. The crushing rollers 7 rotate together, and the crushing rollers 7 drive the adjacent crushing rollers 7 to rotate in the opposite direction through two adjacent and mutually meshing spur gears 11. The output shaft of the second motor 1201 drives the first rotating shaft 1202 to rotate together. The first rotating shaft 1202 drives the second rotating shaft 1203 to rotate together through the first transmission member 1204. The second rotating shaft 1203 drives the second rotating shaft 1203 to rotate together through the pulley belt. The second rotating shaft 1203 drives the two cams thereon to rotate together. The two rotating cams make the dividing plate 3 slide up and down continuously along the column 2, and the elastic member between the column 2 and the dividing plate 3 is repeatedly stretched and reset.

[0039] After the dividing plate 3 starts to move up and down, the staff pours the coal gangue that needs to be crushed into the feed hopper on the left side of the frame 1, and then the coal gangue starts to move downward. When the coal gangue moves downward until it contacts the screen mesh 4, the particles in the coal gangue that are smaller than the aperture of the screen mesh 4 fall downward through the leakage port on the dividing plate 3 to the feeding plate 5 on the left, and the particles in the coal gangue that are larger than the aperture of the screen mesh 4 move to the right along the dividing plate 3 until the large-sized coal gangue breaks away from the dividing plate 3 and falls onto the feeding plate 5 on the right. Then, the coal gangue moves obliquely downward along the adjacent feeding plates 5 under the action of its own gravity until the small-sized coal gangue and the large-sized coal gangue are respectively fed into the crusher. The gangue enters the left and right independent cavities of the crushing shell 6. When the gangue moves downward to contact the adjacent crushing roller 7, the rotating crushing roller 7 crushes the gangue. By dividing the gangue of different particle sizes into different areas and crushing them independently, it is prevented that the gangue of different particle sizes is not excessively or not fully crushed under the action of the same crushing roller 7, thereby improving the crushing effect of the gangue. At the same time, two different sizes of gangue particles are obtained in a single crushing process, thereby improving the diversity of the gangue crushing. During the crushing process, the staff will collect the crushed gangue particles that fall from the left and right independent cavities of the crushing shell 6.

[0040] After the fan 1301 is started, taking the fan 1301 on the right as an example, the fan 1301 starts to draw air to the right. When the crushed gangue passes through the adjacent cleaning shell 8, the dust generated in the crushing process of the gangue begins to move to the right under the action of the adjacent fan 1301. In this process, the granular gangue is intercepted by the filter 1302. During the rotation of the transmission shaft 1001, the transmission shaft 1001 drives the adjacent reciprocating screw 1304 to rotate together through the pulley belt. The scraper 1305 starts to move backward under the action of the adjacent reciprocating screw 1304. The moving scraper 1305 scrapes off the dust on the adjacent filter screen 1302, and at the same time, the scraper 1305 accumulates the accumulated dust in the area of ​​the adjacent dust exhaust pipe 1303 until the dust moves into the adjacent dust exhaust pipe 1303 and is discharged from the frame 1. The staff then collects the discharged dust for subsequent unified processing. The fan 1301 is used to extract the dust generated when crushing the coal gangue, reducing the degree of dust diffusion, improving the quality of the working environment of the staff, and preventing dust from entering the crushed coal gangue product, thereby improving the quality of the crushed coal gangue particles.

[0041] When the scraper 1305 moves backward to contact the rear side of the inner wall of the adjacent cleaning shell 8, as the reciprocating screw 1304 continues to rotate, the scraper 1305 begins to move forward under the action of the reciprocating screw 1304, and accumulates the dust in the adjacent cleaning shell 8 until the scraper 1305 moves forward to scrape the accumulated dust into the dust exhaust pipe 1303 on the front side. The scraper 1305 repeats this cycle until the crushing of the coal gangue is completed. The staff then turns off the two first motors 9, the second motor 1201 and the fan 1301 through the control module and then transfers the crushed coal gangue particles.

The opposite sides of the movable frames 1401 arranged in a left and right mirror image are fixedly connected with the first piston 1402 arranged in a front and rear mirror image.

The feeding pipe 1704 passes through the independent cavity on the right side of the crushing shell 6 and is connected with the independent cavity on the left side of the crushing shell 6. A scraper plate 1705 is fixedly connected to the middle of the first rotating shaft 1202. The scraper plate 1705 is an arc-shaped plate, and the outer edge of the scraper plate 1705 is bent in the clockwise direction. The scraper plate 1705 is used to allow the stone to enter the feeding pipe 1704. The first crushing block 1702 cooperates with the adjacent second crushing block 1703 to pre-crush the excess large-particle gangue, which reduces the subsequent steps of separate crushing and improves the crushing efficiency of the gangue.

[0047] In the process of gangue of different sizes moving downward on the adjacent feeding plates 5, the gangue presses the adjacent moving frame 1401 downward, and the moving frame 1401 starts to move downward, and the moving frame 1401 drives the adjacent first piston 1402 to move downward together, and the adjacent elastic element 1403 is compressed, and the first piston 1402 slides in the adjacent first cylinder 1404. The first piston 1402 on the left squeezes the hydraulic oil in the adjacent first cylinder 1404 into the adjacent first tube 1405, and the first piston 1402 on the right squeezes the hydraulic oil in the adjacent first cylinder 1404 into the adjacent first tube 1405. 02 squeezes the hydraulic oil in the adjacent first cylinder 1404 into the adjacent second tube 1507, and the hydraulic oil in the first tube 1405 squeezes the adjacent second piston 1503 downward, and the second piston 1503 begins to move downward, and the second piston 1503 drives the adjacent rack 1504 to move downward together, and the rack 1504 drives the adjacent threaded rod 1505 to start rotating through the second transmission member 1506, and then the sliding plate 1502 begins to move downward along the adjacent liquid storage shell 1501 under the action of the adjacent threaded rod 1505.

[0048] During the downward movement of the sliding plate 1502, the hydraulic oil in the second tube 1507 enters the adjacent liquid storage shell 1501. If the extrusion pressure exerted by the gangue on the left and right feeding plates 5 on the adjacent movable frame 1401 is equal, the change in volume between the sliding plate 1502 and the adjacent liquid storage shell 1501 is equal to the outflow of the hydraulic oil in the adjacent second tube 1507. If the extrusion pressure exerted by the gangue on the right feeding plate 5 on the adjacent movable frame 1401 is greater than the extrusion pressure exerted by the gangue on the left feeding plate 5 on the adjacent movable frame 1401, the excess hydraulic oil flowing out of the second tube 1507 enters the adjacent third tube 1603, and then the hydraulic oil in the third tube 1603 enters The hydraulic oil enters the adjacent second cylinder 1602, and the hydraulic oil in the second cylinder 1602 begins to squeeze the adjacent third piston 1604. The two third pistons 1604 arranged in a mirror image begin to move backwards, and the third pistons 1604 drive the adjacent opening and closing plates 1601 to move together. The two opening and closing plates 1601 arranged in a front and rear mirror image begin to move backwards, and the excess coal gangue on the right feeding plate 5 falls from the gap between the two opening and closing plates 1601 into the shell 1701 below, thereby ensuring that the amount of coal gangue of different particle sizes in the two independent cavities in the crushing shell 6 is the same, preventing the difference in the crushing effect of the coal gangue in the two different independent cavities in the crushing shell 6, thereby improving the crushing effect of the coal gangue.

[0049] During the rotation of the first rotating shaft 1202, the first rotating shaft 1202 drives several second crushing blocks 1703 and the arc-shaped array of scraper plates 1705 to rotate together. When the coal gangue entering the shell 1701 moves to the area where the first crushing block 1702 and the adjacent second crushing block 1703 cooperate, the large-sized coal gangue is pre-crushed into small-sized particles. After the pre-crushed coal gangue moves downward to the bottom of the shell 1701, the coal gangue enters the feeding pipe 1704 under the action of the adjacent scraper plates 1705, and then the pre-crushed coal gangue enters the independent cavity on the left side of the crushing shell 6 from the feeding pipe 1704 to continue crushing. The first crushing block 1702 and the adjacent second crushing block 1703 cooperate to pre-crush the excess large-sized coal gangue, thereby reducing the subsequent steps of separate crushing and improving the crushing efficiency of the coal gangue.

[0050] Example 3:

[0051] On the basis of Example 2, Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 10As shown, it also includes an adjusting mechanism 18 for changing the ratio of stones of different sizes after crushing. The adjusting mechanism 18 is arranged on the frame 1, and the transmission shaft 1001 is spline-connected to the adjacent sliding shaft 1003. The adjusting mechanism 18 includes an adjusting rod 1801 arranged in a front and rear mirror image, and the adjusting rods 1801 arranged in a front and rear mirror image are both slidably connected to the frame 1. The right-side feeding plate 5 is fixedly connected with a third cylinder 1802 arranged in a mirror image. The third cylinder 1802 is filled with a transmission medium, which is hydraulic oil. The adjusting rod 1801 is threadedly connected to the adjacent third cylinder 1802 so that the adjusting rod 1801 moves to the left under the action of the adjacent third cylinder 1802 when rotating and squeezes the hydraulic oil in the adjacent third cylinder 1802. A fourth pipe 1803 is connected between the third cylinder 1802 and the adjacent second cylinder 1602. An electric push rod 1804 is installed on the front of the upper side of the cleaning shell 8. The telescopic end of the electric push rod 1804 is fixedly connected to a connecting plate 1805. The connecting plate 1 805 is rotationally connected to the adjacent sliding shaft 1003, and drives the adjacent sliding shaft 1003 to move forward and backward through the connecting plate 1805, so that the adjacent transmission disk 1004 moves forward and backward, so that the transmission disk 1004 contacts the areas of different outer diameters of the adjacent transmission wheel 1002, thereby changing the rotation speed of the crushing roller 7 in the independent cavities on the left and right sides of the crushing shell 6, and matching the amount of coal gangue that needs to be crushed, thereby improving the crushing quality of the coal gangue. A position sensor 1806 arranged in a front and rear mirror image is installed on the right side of the frame 1. The position sensor 1806 is electrically connected to the control module. The position sensor 1806 is used to sense the position of the adjacent adjusting rod 1801, and the hydraulic oil in the adjacent third cylinder 1802 is squeezed by the adjusting rod 1801 to change the gap between the mirror-arranged opening and closing plates 1601, and the amount of coal gangue on the right side of the feeding plate 5 falling into the shell 1701 is changed, thereby adjusting the proportion of coal gangue of different particle sizes, thereby improving the applicability of the device.

[0052] When it is necessary to adjust the ratio of coal gangue with different particle sizes after crushing, the staff rotates the two adjusting rods 1801. The adjusting rod 1801 starts to move to the left under the action of the adjacent third cylinder 1802. The adjusting rod 1801 starts to squeeze the hydraulic oil in the adjacent third cylinder 1802. The hydraulic oil in the third cylinder 1802 enters the adjacent second cylinder 1602 through the adjacent fourth pipe 1803 and squeezes the adjacent third piston 1604. The third pistons 1604 arranged in front and back mirror images start to move in reverse, and the third pistons 1604 drive the corresponding The adjacent opening and closing plates 1601 move together, so that part of the coal gangue on the right feeding plate 5 falls into the shell 1701 below through the distance between the mirror-arranged opening and closing plates 1601, and then the coal gangue entering the shell 1701 is pre-crushed. The hydraulic oil in the adjacent third cylinder 1802 is squeezed by the adjusting rod 1801 to change the gap between the mirror-arranged opening and closing plates 1601, and the amount of coal gangue on the right feeding plate 5 falling into the shell 1701 is changed, thereby adjusting the proportion of coal gangue with different particle sizes, thereby improving the applicability of the device.

[0053] During the process of the adjustment rod 1801 moving to the left, the position sensor 1806 monitors the distance between the position sensor 1806 and the right end of the adjacent adjustment rod 1801 in real time. When the position sensor 1806 detects that the distance between the position sensor 1806 and the right end of the adjacent adjustment rod 1801 decreases, the position sensor 1806 transmits an electrical signal to the control module. The control module activates the two electric push rods 1804. The telescopic end of the left electric push rod 1804 starts to move backward, and the telescopic end of the left electric push rod 1804 drives the adjacent connecting plate 1805 to move backward together. The connecting plate 1805 on the left drives the adjacent sliding shaft 1003 to move backward together, and the sliding shaft 1003 on the left drives the adjacent transmission disc 1004 to move backward together. The transmission ratio between the transmission disc 1004 on the left and the adjacent transmission wheel 1002 increases, that is, the speed of the crushing roller 7 located in the independent cavity on the left side of the crushing shell 6 increases, and the telescopic end of the right electric push rod 1804 starts to move forward. The telescopic end of the right electric push rod 1804 drives the adjacent connecting plate 1805 to move forward together, and the connecting plate 180 5 drives the adjacent sliding shaft 1003 to move forward together, and the sliding shaft 1003 on the right side drives the adjacent transmission disc 1004 to move forward together. The transmission ratio between the right transmission disc 1004 and the adjacent transmission wheel 1002 is reduced, that is, the speed of the crushing roller 7 located in the independent cavity on the right side of the crushing shell 6 is reduced. Through the change of the speed of the crushing roller 7 in the independent cavity on the left and right sides of the crushing shell 6, the amount of coal gangue to be crushed is matched with each other, thereby improving the crushing quality of coal gangue. When the ratio of coal gangue with different particle sizes after crushing needs to be adjusted, the crushing roller 7 can be adjusted to the maximum value. When adjusting back to the original ratio, the staff rotates the two adjusting rods 1801 in the opposite direction. The adjusting rod 1801 begins to move to the right under the action of the adjacent third cylinder 1802. The adjusting rod 1801 begins to extract the hydraulic oil in the adjacent third cylinder 1802. The hydraulic oil in the second cylinder 1602 begins to enter the third cylinder 1802 through the adjacent fourth tube 1803. At the same time, the third piston 1604 arranged in a front-to-back mirror image begins to move backwards. The third piston 1604 drives the adjacent opening and closing plate 1601 to move together until the relevant parts are completely reset.
