[0028] It is also noted that, as used herein, "one embodiment" or "an embodiment" means

[0029] Example 1, Reference Figures 1-4For the first embodiment of the present application, the embodiment provides a coal crushing device, which comprises a crusher body 100, a feeding port 101 is arranged on the crusher body 100, a dustproof mechanism 200 is arranged on the feeding port 101, the dustproof mechanism 200 comprises four connecting seats 201 arranged on the feeding port 101, the four connecting seats 201 are respectively located on two sides of the feeding port 101 which are away from each other, a shielding plate 202 is rotatably connected between the two connecting seats 201 on the same side, the shielding plate 202 is provided with a connecting rod on the side away from each other, and the side of the two connecting seats 201 close to each other is provided with a circular groove, the two connecting rods are respectively inserted into the two circular grooves, the shielding plate 202 is rotatably connected with the two connecting seats 201 through the two connecting rods, and the connecting seat 201 is provided with a reset assembly 203 for resetting the shielding plate 202. When the coal is poured on the two shielding plates 202 through the equipment, the two shielding plates 202 rotate under the action of gravity, so that the feeding port 101 is opened, and the material can be poured between the two crushing rollers. When the coal pouring is completed, the next batch of coal has not been transported, that is, the coal will not be increased, so that the coal in the feeding port 101 will be less and less in the crushing process, the reset assembly 203 drives the two shielding plates 202 to slowly reset, and in the process of initial resetting, the coal will always be blocked between the two shielding plates 202, so that the dust generated during crushing of the crushing roller will not be discharged from the top. When the coal is completely dropped, the two shielding plates 202 return to the initial position to close the feeding port 101, so as to avoid dust from being discharged from the feeding port 101, greatly reducing the dust and protecting the health of the workers. When the coal is poured at the beginning, the coal directly falls on the shielding plate 202, and then falls on the crushing roller through the shielding plate 202. The shielding part plays a certain buffering effect, and the two shielding plates 202 are completely reset to close the feeding port 101, which greatly reduces the noise. The two shielding plates 202 can also play a guiding effect, so that the coal is located between the two crushing rollers, greatly increasing the crushing effect of the crushing roller. At the same time, after the feeding port 101 is closed, it can also prevent splashing during the crushing process and cause the workers to be injured.

[0030] Further, the reset assembly 203 comprises a support plate 203a connected with the connecting seat 201, an arc-shaped spring 203b connected with the support plate 203a, and an arc-shaped sleeve 203c, an arc-shaped groove 203d is formed in the arc-shaped sleeve 203c, a sliding block 203e is arranged in the arc-shaped groove 203d, and an arc-shaped rod 203f is connected with the sliding block 203e, one end of the arc-shaped rod 203f away from the sliding block 203e extends out of the sleeve and is connected with the shielding plate 202, the arc-shaped rod 203f and the arc-shaped sleeve 203c ensure the stability of the arc-shaped spring 203b when the arc-shaped spring 203b is stretched or reset, when the coal is poured on the shielding plate 202, the shielding plate 202 is rotated around the connecting seat 201 to the direction close to the center of the feeding port 101 under the gravity of the coal, the shielding plate 202 drives the arc-shaped spring 203b to stretch and the arc-shaped rod 203f to move to the outside of the arc-shaped groove 203d, the arc-shaped rod 203f drives the sliding block 203e to slide in the arc-shaped groove 203d, when there is no coal on the shielding plate 202, the shielding plate 202 is reset under the elastic force of the arc-shaped spring 203b, and the feeding port 101 is shielded.

[0031] Further, a buffer pad 203d-1 is arranged on the inner wall of one end of the arc-shaped groove 203d away from the support plate 203a, when the coal is poured at the beginning, the gravity is large, the shielding plate 202 is quickly rotated, the shielding plate 202 drives the arc-shaped rod 203f to extend and the arc-shaped spring 203b to stretch, the arc-shaped rod 203f collides with the buffer pad 203d-1 through the sliding block 203e, and the buffering effect of the buffer pad 203d-1 greatly reduces the possibility of damage of the device.

[0032] Further, the moving track of the arc-shaped groove 203d matches the sliding block 203e, when the shielding plate 202 is in a horizontal state, the sliding block 203e is attached to the inner wall of one end of the arc-shaped groove 203d, and the arc-shaped rod 203f moves in the arc-shaped groove 203d through the sliding block 203e, the rotating angle of the shielding plate 202 is limited, and the rotating angle of the shielding plate 202 is between 15 degrees and 45 degrees.

[0033] In use, when the coal is poured on the shielding plate 202, the shielding plate 202 is rotated under the gravity of the coal, the shielding plate 202 drives the arc-shaped spring 203b to stretch and the arc-shaped rod 203f to move to the outside of the arc-shaped groove 203d, the arc-shaped rod 203f drives the sliding block 203e to slide in the arc-shaped groove 203d, the feeding port 101 is opened, and the coal falls between the two crushing rollers, when there is no coal on the shielding plate 202, the shielding plate 202 is reset under the elastic force of the arc-shaped spring 203b, and the feeding port 101 is shielded, the arrangement not only can make the coal pour between the two crushing rollers, increase the crushing effect, but also can play a dustproof and noise reduction role.

[0034] Embodiment 2, refer toFigures 2-5 For the second embodiment of the present application, unlike the previous embodiment, the embodiment further comprises a limiting mechanism 300 connected with the connecting seat 201. The limiting mechanism 300 comprises a horizontal plate 301 connected with the connecting seat 201, a mounting groove 302 opened on the horizontal plate 301, an extrusion assembly 303 arranged inside the mounting groove 302, and a limiting groove 304 opened on the feeding port 101. Through the arrangement of the extrusion assembly 303, the position of the connecting seat 201 can be fixed.

[0035] Further, the blocking plate 202 and the connecting seat 201 are both provided with positioning grooves 201a, and the arc-shaped rod 203f away from the sliding block 203e is provided with a positioning block 201b close to the end of the connecting seat 201. The two positioning blocks 201b can slide in and out of the corresponding positioning grooves 201a, and the two positioning grooves 201a and the two positioning blocks 201b are polygons, which can ensure that the device will not be separated when the blocking plate 202 rotates. When the arc-shaped spring 203b has been used for a long time and the elastic force is low, the device is pushed to the side of the feeding port 101, so that the two positioning blocks 201b can slide out of the two positioning grooves 201a, thereby disconnecting the connection between the resetting assembly 203 and the blocking plate 202 and the connecting seat 201, and the arc-shaped spring 203b can be processed.

[0036] Further, the feeding port 101 is provided with an auxiliary groove 101a, and the auxiliary groove 101a is provided with an auxiliary block 101b. The auxiliary block 101b is connected with the bottom of the connecting seat 201. The arrangement of the auxiliary groove 101a and the auxiliary block 101b ensures the connection between the connecting seat 201 and the feeding port 101. At the same time, by pushing the connecting seat 201 to the side of the feeding port 101, the circular groove on the connecting seat 201 and the connecting rod on the blocking plate 202 are dislocated, so that the blocking plate 202 can be replaced.

[0037] The remaining structures are the same as those of the first embodiment.

[0038] In use, when the blocking plate 202 is damaged by long-term impact of coal, the connecting seat 201 is pushed to the side of the feeding port 101, so that the circular groove on the connecting seat 201 and the connecting rod on the blocking plate 202 are dislocated, and the blocking plate 202 can be replaced. When the connecting seat 201 is pushed, the positioning block 201b on the blocking plate 202 also slides out of the positioning groove 201a on the blocking plate 202, thereby disconnecting the blocking plate 202. When the resetting assembly 203 is also damaged, the positioning block 201b connected with the supporting plate 203a is pushed to the side of the feeding port 101, so that the supporting plate 203a and the positioning block 201b are disconnected from the positioning groove 201a on the connecting seat 201, thereby disconnecting the resetting assembly 203 and the connecting seat 201. The whole process is simple and fast.
