[0007] The crushing box has a feed inlet on the upper surface and a discharge gate on one side surface; the feed end is installed on the upper surface of the crushing box and is located at the feed inlet.

[0008] The primary and secondary crushing components are installed side-by-side inside the crushing chamber; two rotating shafts are rotatably mounted side-by-side on the crushing chamber; one end of each crushing roller is rotatably mounted on the two rotating shafts, and the other end of each crushing roller is rotatably mounted inside the crushing chamber, with the central axis of each crushing roller parallel to the central axis of each rotating shaft; two sets of crushing blades are respectively mounted on the two crushing rollers, and the two sets of crushing blades are staggered; two primary motors are respectively mounted on the two rotating shafts, and the output shafts of the two primary motors pass through the two rotating shafts and are respectively connected to the two crushing rollers;

[0009] The crushing box is equipped with a drive assembly for driving the two rotating shafts to rotate.

[0010] Preferably, the secondary crushing assembly includes a grinding block, a grinding table, a rotating shaft, and a third motor; two support plates are arranged side by side on the bottom surface of the crushing box; the grinding block is installed inside the crushing box, located directly below the primary crushing assembly, and has a grinding hole in the center; the diameter of the grinding hole gradually decreases in the vertically downward direction; the grinding table is frustum-shaped and located inside the grinding hole; the distance between the outer circumference of the grinding table and the inner wall of the grinding hole gradually decreases in the vertically downward direction; the third motor is installed on the bottom surface of the crushing box, the output shaft of the third motor extends into the crushing box, and the output shaft of the third motor is rotatably mounted on the crushing box; the rotating shaft is located inside the crushing box, and its two ends are respectively connected to the output shaft of the third motor and the bottom surface of the grinding table.

[0011] Preferably, it also includes a guide plate; the guide plate is installed inside the crushing box and is inclined downward toward the discharge gate; the central part of the rotating shaft is rotatably mounted on the guide plate.

[0012] Preferably, it also includes multiple stirring shafts, impact blocks, rubber rings, and swing rods; multiple stirring shafts are all mounted on rotating shafts; the guide plate is provided with mounting holes; the rubber rings are installed in the mounting holes; the middle part of the swing rod passes through the middle of the rubber ring, and the end of the swing rod located below the guide plate is connected to the impact blocks.

[0013] Preferably, it also includes a limiting block; the limiting block is installed inside the crushing box, and the end of the limiting block facing the impact block has a groove.

[0014] Preferably, it also includes multiple reinforcing plates; the multiple reinforcing plates are staggered with multiple stirring shafts, and the two ends of each reinforcing plate are respectively connected to two adjacent stirring shafts.

[0015] Preferably, the multiple reinforcing plates and multiple stirring shafts are integrally formed.

[0016] Preferably, the drive assembly includes two meshing gears and a second motor; the second motor is installed outside the crushing chamber, and a drive gear is provided on the output shaft of the second motor; the two meshing gears are respectively installed on two rotating shafts, and the two meshing gears are meshed together, with one of the meshing gears meshing with the drive gear.

[0017] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:

[0018] The user feeds ore into the crushing chamber through the feed end. Then, the second motor drives the drive gear to rotate, which in turn drives the two meshing gears to rotate the two rotating shafts. Since the crushing rollers are not coaxial with the rotating shafts, the distance between the two crushing rollers changes when the two rotating shafts rotate, effectively preventing the ore from getting stuck between the crushing rollers and allowing for smooth crushing. The height of the two crushing rollers also changes, allowing the ore entering the crushing chamber to be pushed and repositioned, crushing all the ore entering. At the same time, the first motor drives the two crushing rollers to rotate, and two sets of crushing blades crush the ore. The ore falling between the two crushing rollers falls between the grinding hole and the grinding table for further crushing, allowing the ore to be crushed to the required particle size.

[0019] The user drives multiple agitator shafts to rotate via a rotating shaft, which agitates the crushed ore on the guide plate, making the crushed ore loose and easier for the guide plate to discharge it through the discharge gate. At the same time, the rotation of the agitator shafts pushes the swing rod to swing, which in turn drives the impact block to strike the guide plate, allowing the crushed ore accumulated on the guide plate to be quickly discharged through the discharge gate, further reducing the chance of the crushed ore getting stuck at the discharge gate.

[0020] Users connect multiple stirring shafts with multiple reinforcing plates, thereby increasing the strength of the multiple stirring shafts; at the same time, through a molded structure, the strength between the multiple reinforcing plates and the multiple stirring shafts is further enhanced, extending the service life of the multiple reinforcing plates and the multiple stirring shafts.

[0027] like Figures 1-3 As shown, the present invention proposes a multi-stage crushing and sorting device for mining ore, including a crushing box 1, a feeding end 7, a primary crushing component 23 and a secondary crushing component; the primary crushing component 23 includes two first motors 4, two rotating shafts 5, two crushing rollers 8 and two sets of crushing blades 9.

[0028] The upper end face of the crushing box 1 is provided with a feed inlet 101, and the side end face of the crushing box 1 is provided with a discharge gate 3; the feed end 7 is installed on the upper end face of the crushing box 1, and the feed end 7 is located at the feed inlet 101.

[0029] The primary crushing assembly 23 and the secondary crushing assembly are installed side by side inside the crushing box 1; two rotating shafts 5 are rotatably mounted side by side on the crushing box 1; one end of each of the two crushing rollers 8 is rotatably mounted on the two rotating shafts 5, and the other end of each crushing roller 8 is rotatably mounted inside the crushing box 1, with the central axis of each crushing roller 8 being parallel to the central axis of each rotating shaft 5; two sets of crushing blades 9 are respectively mounted on the two crushing rollers 8, and the two sets of crushing blades 9 are staggered; two first motors 4 are respectively mounted on the two rotating shafts 5, and the output shafts of the two first motors 4 pass through the two rotating shafts 5 and are respectively connected to the two crushing rollers 8.

[0030] The crushing box 1 is equipped with a drive assembly for driving the two rotating shafts 5 to rotate. The drive assembly includes two meshing gears 6 and a second motor 15; the second motor 15 is installed outside the crushing box 1, and a drive gear is provided on the output shaft of the second motor 15; the two meshing gears 6 are respectively installed on the two rotating shafts 5, and the two meshing gears 6 are meshed together, with one of the meshing gears 6 meshing with the drive gear.

[0031] The secondary crushing assembly includes a grinding block 10, a grinding table 11, a rotating shaft 13, and a third motor 14. Two support plates 2 are arranged side-by-side on the bottom surface of the crushing chamber 1. The grinding block 10 is installed inside the crushing chamber 1, directly below the primary crushing assembly 23, and has a grinding hole 1001 in its center. The diameter of the grinding hole 1001 gradually decreases vertically downwards. The grinding table 11 is frustum-shaped and located inside the grinding hole 1001. The distance between the outer circumference of the grinding table 11 and the inner wall of the grinding hole 1001 gradually decreases vertically downwards. The third motor 14 is installed on the bottom surface of the crushing chamber 1, and its output shaft extends into the crushing chamber 1, rotating on the crushing chamber 1. The rotating shaft 13 is located inside the crushing chamber 1, with its two ends connected to the output shaft of the third motor 14 and the bottom surface of the grinding table 11, respectively.

[0032] In this invention, during use, the user feeds ore into the crushing box 1 through the feed end 7. Then, the second motor 15 drives the drive gear to rotate, which in turn causes the two meshing gears 6 to drive the two rotating shafts 5 to rotate. Since the crushing rollers 8 are not coaxial with the rotating shafts 5, the distance between the two crushing rollers 8 changes when the two rotating shafts 5 rotate, effectively preventing the ore from getting stuck between the two crushing rollers 8 and allowing for smooth crushing of the ore. The height of the two crushing rollers 8 also changes, allowing the ore entering the crushing box 1 to be pushed and repositioned, crushing all the ore that enters. At the same time, the first motor 4 drives the two crushing rollers 8 to rotate, and the two sets of crushing blades 9 crush the ore. The ore falling between the two crushing rollers 8 falls between the grinding hole 1001 and the grinding table 11 for further crushing, so that the ore can be crushed to the required particle size. Example

[0033] like Figure 2 As shown, the present invention proposes a multi-stage crushing and sorting device for mining ore. Compared with the first embodiment, this embodiment also includes a guide plate 12. The guide plate 12 is installed in the crushing box 1 and is inclined downward toward the discharge gate 3. The rotating shaft 13 is rotatably mounted on the guide plate 12 in the middle.

[0034] In this invention, during use, the user guides the secondary crushed ore to the discharge gate 3 via the guide plate 12 for output and collection, thereby improving the practicality of the device. Example

[0035] like Figure 5As shown, the multi-stage crushing and sorting device for mining ore proposed in this invention, compared with Embodiment 1, further includes multiple stirring shafts 16, impact blocks 20, rubber rings 21, and swing rods 22; the multiple stirring shafts 16 are all mounted on rotating shafts 13; the guide plate 12 is provided with mounting holes; the rubber rings 21 are installed in the mounting holes; the middle part of the swing rod 22 passes through the middle part of the rubber ring 21, and the end of the swing rod 22 located below the guide plate 12 is connected to the impact blocks 20. It also includes a limiting block 18; the limiting block 18 is installed inside the crushing box 1, and the end of the limiting block 18 facing the impact blocks 20 is provided with a groove 19.

[0036] In this invention, during use, the user drives multiple stirring shafts 16 to rotate via the rotating shaft 13. The stirring shafts 16 then stir the crushed ore on the guide plate 12, making the interior of the crushed ore loose and facilitating the guide plate 12 to output the crushed ore through the discharge gate 3. At the same time, the rotation of the stirring shafts 16 pushes the swing rod 22 to swing, which in turn drives the striking block 20 to impact the guide plate 12. This allows the crushed ore accumulated on the guide plate 12 to be quickly output through the discharge gate 3, further reducing the probability of the crushed ore getting stuck at the discharge gate 3. Example

[0037] like Figure 5 As shown, the present invention proposes a multi-stage crushing and sorting device for mining ore. Compared with Embodiment 1, this embodiment also includes multiple reinforcing plates 17. The multiple reinforcing plates 17 and multiple stirring shafts 16 are staggered. The two ends of each reinforcing plate 17 are respectively connected to two adjacent stirring shafts 16. The multiple reinforcing plates 17 and multiple stirring shafts 16 are integrally formed, and the connection between the integrally formed reinforcing plates 17 and multiple stirring shafts 16 is more solid.

[0038] In this invention, during use, the user connects multiple stirring shafts 16 with multiple reinforcing plates 17, thereby improving the strength of the multiple stirring shafts 16; at the same time, through a molding structure, the strength between the multiple reinforcing plates 17 and the multiple stirring shafts 16 is further strengthened, extending the service life of the multiple reinforcing plates 17 and the multiple stirring shafts 16.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
