[0002] Iron ore is an important mineral resource, but the grade of iron ore in my country is relatively low. After underground mining, it needs to be crushed by a crusher in time to facilitate the later extraction of iron. For example, the authorization announcement number CN216779040U mentions a multi-stage processing iron ore mining crusher, which includes a shell stably set on the ground, and a feed port is provided at the top of the shell, and a discharge port is provided at the bottom of the outer side of the shell, and a motor is installed on the rear side of the shell, and also includes: a crushing roller is provided at the top of the inner side of the shell, and a grinding chamber is provided above the inner side of the shell, and a filter is installed in the middle of the inner side of the shell, a column is installed on the top of the shell, and a tamping rod is connected to the side of the column, and a bump turntable is connected to the bottom of the column, and a second knocking rod is connected to the outer side of the bump turntable.

[0003] In this device, iron ore can be crushed and pounded at the feed port, which is conducive to the input of iron ore. However, in actual application, researchers found that when pounding at the feed port, it is not convenient to pound at multiple positions, and the pounding rod cannot pound reciprocally, the pounding effect is poor, which is not conducive to promotion and use.

[0023] When in use, first place the processing box 1 in a suitable position, then put the iron ore mined underground into the processing box 1 through the feed port 2, and crush it through the rotation and extrusion of the crushing roller 18, and fall to the top surface of the filter plate 19. When the fine grinding motor at the bottom of the processing box 1 drives the rotation of the rotating rod 20, it drives the rotation of the fine grinding roller to finely grind the iron ore, and then it is filtered through the filter plate 19 and discharged from the processing box 1.

[0024] It should be noted that: Figure 2 The top surface of the pressing rod 13 is an inclined smooth surface, that is, when the extension rod 11 and the roller 12 assembly rotates under the drive motor 10, the roller 12 hits the inclined surface of the pressing rod 13, causing the pressing rod 13 to move downward.

[0025] As an optimal technical solution for a crusher used in underground iron ore mining according to the utility model, a crushing roller 18 is provided in the inner cavity of the processing box 1, and the number of the crushing rollers 18 is two; the front and rear ends of the two crushing rollers 18 are fixedly connected with a rotating rod, and the front and rear ends of the two rotating rods are movably connected to the processing box 1 through bearings, and the rear ends of the two rotating rods are movably connected to the processing box 1 through bearings, and are fixedly connected with gear plates, the two gear plates are meshed and connected, and the rear end of one gear plate is fixedly connected to the rotating motor, and the rotating motor can drive the rotation of the two gear plates, thereby driving the rotation of the rotating rod and the crushing rollers 18, and crushing the iron ore mined underground. This is a common technical means and will not be explained in detail here.

[0026] As an optimal technical solution for a crusher used in underground iron ore mining according to the present invention, a filter plate 19 is fixedly connected to the inner surface of the processing box 1, and the top surface of the filter plate 19 is movably connected to the rotating rod 20 through a bearing, and a fine grinding roller is fixedly connected to the outer surface of the rotating rod 20; a fine grinding motor is fixedly connected to the center of the bottom surface of the processing box 1, and the fine grinding motor drives the rotation of the rotating rod 20, thereby driving the rotation of the fine grinding roller, finely grinding the crushed iron ore, and discharging it to the outside after being filtered by the filter plate 19.

[0027] As an optimal technical solution for an underground iron ore mining crusher of the present invention, a telescopic rod 22 is provided in the inner cavity of the return spring 16, the top of the telescopic rod 22 is fixedly connected to the protruding block 15, the bottom of the telescopic rod 22 is fixedly connected to the fixed plate 8, and the bottom of the return spring 16 is fixedly connected to the fixed plate 8; the positions of the return spring 16 and the telescopic rod 22 are described, and as shown in FIG. Figure 2 As shown, a sealing rubber soft layer is provided on the outside of the reset spring 16 , and the upper and lower ends of the sealing rubber soft layer are fixedly connected to the protruding block 15 and the fixing plate 8 respectively, which can prevent debris from entering between the reset spring 16 .

[0028] As an optimal technical solution for a crusher used in underground iron ore mining according to the present invention, the vertical section of the limit plate 17 is an L-shaped structure, and the top surface of the inner cavity of the limit plate 17 is slidably connected to the protruding block 15; it can effectively prevent the protruding block 15 and the lower pressure rod 13 combination from excessive upward movement, and ensure that when the electric push rod 7 is contracted, the lower pressure rod 13 and the ramming rod 14 combination can ram down the iron ore at the feed port 2.

[0029] Example 2

[0030] See also Figure 3 The difference between this embodiment and embodiment 1 is that:

[0031] One end of the threaded rod 5 is fixedly connected to the output end of the servo motor 4, and the end of the threaded rod 5 away from the servo motor 4 is movably connected to the guide rail box 3 through a bearing; the bottom surface of the moving plate 6 is fixedly connected to the sliding block 21, and the sliding block 21 is threadedly connected to the outer surface of the threaded rod 5, and the top surface of the guide rail box 3 is provided with a sliding groove that matches the structural size of the sliding block 21; the threaded rod 5 is driven to rotate by the servo motor 4. At this time, as the rotation direction of the threaded rod 5 is different, the moving plate 6, the electric push rod 7 and the tamping rod 14 combination performs reciprocating motion in the direction of the guide rail box 3.

[0032] It should be noted that: through personnel in this field, all electrical components in this case, such as the servo motor 4, the electric push rod 7, the drive motor 10, etc., are connected to their corresponding power supplies through wires, and a suitable controller, such as a PLC controller or a single-chip microcomputer, should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working. The detailed connection means are well known in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0033] The working principle and use process of the present invention are as follows: when the iron ore enters the feed port 2, if it is blocked, the feed port 2 needs to be tamped. At this time, the servo motor 4 drives the rotation of the threaded rod 5. Since the sliding block 21 on the bottom surface of the moving plate 6 is threadedly connected to the outer surface of the threaded rod 5, as the threaded rod 5 rotates, the moving plate 6, the electric push rod 7 and the tamping rod 14 assembly move in the direction of the guide box 3, controlling the contraction of the electric push rod 7, which can drive the fixed plate 8 and the lower pressure rod 13 to move. As the tamping rod 14 falls, the feed port 2 can be tamped. Further, the start of the drive motor 10 is controlled, and the drive motor 10 drives the extension rod 11 and the roller 12 to rotate. The roller 12 hits the top surface of the lower pressure rod 13. At this time, the lower pressure rod 13 and the tamping rod 14 combination falls, and the return spring 16 is deformed to generate elastic force. When the roller 12 leaves the lower pressure rod 13, the return spring 16 returns to its original shape, driving the lower pressure rod 13 and the tamping rod 14 to rise, and so on, to better complete the tamping work.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
