At the same time, the original device cannot cushion and reduce the shock of the sample added to the shell. After the sample is added to the shell, it directly hits the grinding wheel, which can easily cause damage to the grinding wheel. Utility Model Content

[0027] When the sample crushing device for geological and mineral exploration is used, the device is installed in a suitable position, the motor 5 is turned on to drive the grinding wheel 6 to rotate, and the sample is placed into the housing 1 through the feed hopper 3. The sample is ground by the two grinding wheels 6 and falls onto the filter plate 7. Qualified samples pass through the filter plate 7 and enter the collection box 9, and unqualified samples enter the collection box 4 through the discharge port 8. The dust reduction component 2 is provided to generate dust when crushing the sample. The fan 23 is turned on. The fan 23 forms a negative pressure in the dust inlet 26 at one end of the fixed pipe 25 through the dust reduction box 22 and the connecting pipe 27. The dust enters the dust reduction box 22 through the dust inlet 26, the fixed pipe 25 and the connecting pipe 27. The dust-laden air is filtered by the filter screen 24 in the dust reduction box 22 and discharged from the dust reduction box 22. The dust generated by the crushing can be reduced by providing the dust reduction component 2, thereby reducing the pollution of the dust to the air. The installation component 28 is set up, and the filter screen 24 is installed into the dust suppression box 22 through the installation port 282. The lower end of the filter screen 24 enters the groove 285 at the lower end of the dust suppression box 22. Then the installation plate 281 is placed on the upper end of the installation port 282, and the upper end of the filter screen 24 enters the groove 285 at the lower end of the installation plate 281. Finally, the fixing bolt 283 is screwed into the fixing hole 284 to fix the installation plate 281.

[0028] The difference between this embodiment and embodiment 1 is that: a folding plate 11 is provided at a position corresponding to the feed hopper 3 on the upper side of the inner part of the shell 1, two connecting rods 14 are provided at both ends of the folding plate 11, a movable plate 13 is provided at the other end of the connecting rod 14, a fixed plate 12 is provided on the lower side of the movable plate 13, damping rods 15 are provided on both sides between the movable plate 13 and the fixed plate 12, a spring 16 is provided on the outside of the damping rod 15 between the movable plate 13 and the fixed plate 12, and an inclined plate 10 is provided at a position corresponding to the folding plate 11 on the upper side of both ends of the inner part of the shell 1.

[0029] By adopting the above technical solution, after the sample is added into the shell 1 through the feed hopper 3, the sample contacts the folding plate 11. After the folding plate 11 is impacted, the connecting rod 14 pushes the movable plate 13 to compress the damping rod 15 and the spring 16. The damping rod 15 and the spring 16 can play a buffering role on the folding plate 11. Then the sample falls onto the inclined plate 10 and is drained into the grinding wheel 6 through the inclined plate 10 for crushing. By providing the folding plate 11 and the inclined plate 10, the sample added into the shell 1 can be buffered and shock-absorbing, thereby preventing the sample from directly hitting the grinding wheel 6 after being added to the shell 1, which may cause damage to the grinding wheel 6.

[0030] Specifically, the side of the movable plate 13 is tangent to the inner wall of the shell 1 , and the fixed plate 12 and the shell 1 as well as the folding plate 11 and the connecting rod 14 are all welded by spot welding.

[0031] By adopting the above technical solution, the movable plate 13 will not scratch the inner wall of the shell 1, and the spot welding makes the connection between the fixed plate 12 and the shell 1 and between the folding plate 11 and the connecting rod 14 stronger.

[0032] When this embodiment is used, by setting the folding plate 11, after the sample is added into the shell 1 through the feed hopper 3, the sample contacts the folding plate 11. After the folding plate 11 is impacted, the connecting rod 14 pushes the movable plate 13 to compress the damping rod 15 and the spring 16. The damping rod 15 and the spring 16 can buffer the folding plate 11. Then the sample falls onto the inclined plate 10 and is drained into the grinding wheel 6 through the inclined plate 10 for crushing. By setting the folding plate 11 and the inclined plate 10, the sample added to the shell 1 can be buffered and shock-absorbing, so as to avoid the sample directly hitting the grinding wheel 6 after being added to the shell 1, which may cause damage to the grinding wheel 6.

[0033] The blower 23 of the present invention is an existing disclosed technology, and the selected model is 4-72C.

[0034] The damping rod 15 in the present invention is an existing disclosed technology, and the selected model is SQS.

[0035] The structure and working principle of the shell 1, feed hopper 3, collection box 4, motor 5, grinding wheel 6, filter plate 7, discharge port 8 and collection box 9 in the utility model have been disclosed in a sample crushing device for geological and mineral exploration disclosed in Chinese patent application No. 2023212839356. Its working principle is to turn on the motor 5 to drive the grinding wheel 6 to rotate, put the sample into the shell 1 through the feed hopper 3, and the sample falls on the filter plate 7 after being ground by two grinding wheels 6. Qualified samples enter the collection box 9 through the filter plate 7, and unqualified samples enter the collection box 4 through the discharge port 8.

[0036] The working process of the present utility model is as follows: when the sample crushing device for geological and mineral exploration is used, the device is installed in a suitable position, the motor 5 is turned on to drive the grinding wheel 6 to rotate, and the sample is placed into the housing 1 through the feed hopper 3. The sample is ground by the two grinding wheels 6 and falls onto the filter plate 7. Qualified samples pass through the filter plate 7 and enter the collection box 9, while unqualified samples enter the collection box 4 through the discharge port 8. A dust reduction component 2 is provided. When the sample is crushed, dust is generated. The fan 23 is turned on. The fan 23 forms a negative pressure in the dust inlet 26 at one end of the fixed pipe 25 through the dust reduction box 22 and the connecting pipe 27. Dust enters the dust reduction box 22 through the dust inlet 26, the fixed pipe 25 and the connecting pipe 27. The dust-laden air is filtered by the filter screen 24 in the dust reduction box 22 and discharged from the dust reduction box 22. The dust generated by the crushing can be reduced by providing the dust reduction component 2, thereby reducing the pollution of the air by dust. An installation component 28 is provided, and the filter 24 is installed into the dust suppression box 22 through the installation port 282. The lower end of the filter 24 enters the groove 285 at the lower end of the dust suppression box 22. Then the installation plate 281 is placed on the upper end of the installation port 282. The upper end of the filter 24 enters the groove 285 at the lower end of the installation plate 281. Finally, the fixing bolt 283 is screwed into the fixing hole 284 to fix the installation plate 281. The installation component 28 is provided to facilitate the disassembly and cleaning of the filter 24. By setting the folding plate 11, after the sample is added into the shell 1 through the feed hopper 3, the sample contacts the folding plate 11. After the folding plate 11 is impacted, the connecting rod 14 pushes the movable plate 13 to compress the damping rod 15 and the spring 16. The damping rod 15 and the spring 16 can buffer the folding plate 11. Then the sample falls onto the inclined plate 10 and is drained into the grinding wheel 6 through the inclined plate 10 for crushing. By setting the folding plate 11 and the inclined plate 10, the sample added into the shell 1 can be buffered and shock-absorbing, so as to avoid the sample directly hitting the grinding wheel 6 after being added into the shell 1, which may cause damage to the grinding wheel 6.
