[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] In this embodiment of the present invention, please refer to Figures 1 to 5. A coal crusher for coal mining includes a crushing frame 1, and further includes:

[0045] The crushing roller 2 is located inside the crushing frame 1 and is rotatably connected to the crushing roller 2. The crushing roller 2 is provided in several groups, and one group of the crushing roller 2 is connected to the output end of the motor.

[0046] Gear 3 is connected to crushing roller 2, and two adjacent sets of gears 3 mesh with each other;

[0047] The discharge frame 9, located at the top of the crushing frame 1, is used to store coal.

[0048] The transverse reciprocating component is connected to the discharge frame 9 at one end and to the crushing frame 1 at the other end, and is used to drive the discharge frame 9 to move laterally reciprocating.

[0049] The discharge rate adjustment mechanism is connected to the bottom of the discharge frame 9 and is used to adjust the discharge rate.

[0050] The shaking mechanism is connected to the crushing frame 1 at one end and to the transverse reciprocating component at the other end, and is used to drive the discharge frame 9 to shake.

[0051] Coal is poured into the discharge frame 9. The discharge rate adjustment mechanism adjusts the discharge rate according to actual needs. Coal falls from the discharge frame 9 into the crushing frame 1. The motor (not shown in the figure) drives a set of crushing rollers 2 to rotate. Due to the meshing transmission of gear 3, other sets of crushing rollers 2 also rotate synchronously, crushing the coal entering the crushing frame 1. The transverse reciprocating component starts to work, driving the discharge frame 9 to move laterally in the horizontal direction, so that the coal in the discharge frame 9 can fall evenly into the crushing frame 1, avoiding coal accumulation in the discharge frame 9. During the movement of the discharge frame 9, the shaking mechanism causes the discharge frame 9 to shake longitudinally, which can further promote the falling of coal, prevent coal from blocking or accumulating in the discharge frame 9, and ensure smooth coal transportation.

[0052] As one embodiment of this utility model, please refer to Figure 1. The lateral reciprocating component includes:

[0053] Fixed rod 4 is connected to crushing frame 1;

[0054] The sliding sleeve 5 is slidably connected to the fixed rod 4;

[0055] The telescopic component 6 is connected at one end to the crushing frame 1 and at the other end to the sliding sleeve 5;

[0056] The sliding folding rod 7 is slidably connected to the sliding sleeve 5, and its top end is connected to the discharge frame 9;

[0057] The elastic element 8 is connected at its bottom end to the sliding sleeve 5 and at its top end to the bottom end of the sliding folding rod 7.

[0058] The telescopic component 6 extends and retracts, pushing the sliding sleeve 5 to slide on the fixed rod 4. The sliding of the sliding sleeve 5, via the sliding lever 7, causes the discharge frame 9 to reciprocate laterally in the horizontal direction, ensuring that the coal in the discharge frame 9 falls evenly into the crushing frame 1, preventing coal accumulation in the discharge frame 9. The telescopic component 6 can be an electric telescopic rod, a cylinder, etc. The elastic component 8 can be a spring, a sheet spring, etc.

[0059] As one embodiment of this utility model, please refer to Figures 1 to 3. The discharge rate adjustment mechanism includes:

[0060] Rotating rod 10 is connected to discharge frame 9;

[0061] The sealing plate 11 is rotatably connected to the rotating rod 10;

[0062] Telescopic component 214, one end of which is connected to the discharge frame 9;

[0063] Toothed plate 15 is connected to the other end of telescopic component 14;

[0064] Gear 16 is connected to the sealing plate 11 and meshes with the toothed plate 15.

[0065] By controlling the extension and retraction of the telescopic component 14, the toothed plate 15 is moved, and the toothed plate 15 meshes with the gear 16, causing the gear 16 to rotate. This, in turn, causes the sealing plate 11 to rotate around the rotating rod 10, changing the relative position of the sealing plate 11 and the discharge port, thereby adjusting the size of the discharge port and achieving precise control of the discharge amount. The telescopic component 14 can be an electric telescopic rod, a cylinder, etc.

[0066] As one embodiment of this utility model, please refer to Figures 1 and 5. The shaking mechanism includes:

[0067] The limiting groove 17 is formed on the sliding sleeve 5;

[0068] The abutment rod 18 is connected to the sliding folding rod 7 and is located within the limiting slide groove 17, and is slidably engaged with it;

[0069] Connecting plate 19 is connected to crushing frame 1;

[0070] A hemisphere 20 is connected to a connecting plate 19. The hemisphere 20 is provided in several groups and is arranged in a straight line with equal spacing.

[0071] The lateral movement of the sliding lever 7 drives the synchronous lateral movement of the abutment lever 18. During the movement of the abutment lever 18, it comes into contact with the hemisphere 20, causing the abutment lever 18 to slide within the limiting groove 17. The interaction between the abutment lever 18 and the hemisphere 20 generates a regular impact force, causing the discharge frame 9 to vibrate. This vibration can further promote the falling of coal, prevent coal from clogging or accumulating in the discharge frame 9, and ensure smooth coal transportation.

[0072] As one embodiment of this utility model, please refer to Figures 1 and 2, it also includes:

[0073] Arc plate 12 is connected to sealing plate 11;

[0074] The arc sleeve 13 is connected to the inner wall of the discharge frame 9 and is rotatably connected to the arc plate 12.

[0075] The arc plate 12 and arc sleeve 13 allow coal to enter the crushing frame 1 more smoothly when passing through the discharge port, reducing the retention and accumulation of coal at the discharge port, and further improving the working efficiency and stability of the coal crusher.

[0076] The working principle of this utility model is as follows: When coal crushing operation is required, the coal is first put into the discharge frame 9, the motor is started, and a set of crushing rollers 2 are driven to rotate. Due to the meshing transmission of gear 3, other sets of crushing rollers 2 also rotate synchronously to crush the coal entering the crushing frame 1.

[0077] Simultaneously, the transverse reciprocating assembly begins to operate: the telescopic component 6 extends and retracts, pushing the sliding sleeve 5 to slide on the fixed rod 4. The sliding of the sliding sleeve 5 drives the discharge frame 9 to perform transverse reciprocating motion in the horizontal direction through the sliding folding rod 7, so that the coal in the discharge frame 9 can fall evenly into the crushing frame 1, avoiding the accumulation of coal in the discharge frame 9.

[0078] The discharge rate adjustment mechanism adjusts the discharge rate according to actual needs: by controlling the extension and retraction of the telescopic component 14, the toothed plate 15 is moved, the toothed plate 15 meshes with the gear 16, causing the gear 16 to rotate, which in turn drives the sealing plate 11 to rotate around the rotating rod 10, changing the relative position of the sealing plate 11 and the discharge port, thereby adjusting the size of the discharge port and achieving precise control of the discharge rate.

[0079] The shaking mechanism also plays a role in the operation: the movement of the sliding folding rod 7 causes the abutment rod 18 to slide within the limiting groove 17. The abutment rod 18 interacts with the hemisphere 20 to generate a regular impact force, causing the discharge frame 9 to shake. This shaking can further promote the falling of coal, prevent coal from being blocked or accumulated in the discharge frame 9, and ensure the smooth transportation of coal.

[0080] Through the synergistic effect of the above-mentioned components, this utility model can achieve functions such as efficient coal crushing, uniform feeding, precise control of output, and prevention of coal accumulation, effectively improving the efficiency and quality of coal mining and having important practical application value.

[0081] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0082] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
