Description

Technical Field

[0002] Currently, during the process of geological and mineral exploration, it is necessary to perform crushing and refinement processing on the collected ore samples, and then conduct component detection and analysis on the refined ore samples.

[0003] In the prior art, the crushing of ore samples is mostly achieved by means of a crusher. When the existing crusher works, the crushing roller rolls along the surface of the tooth plate, and the crushing of the ore samples is realized by means of the shearing and rolling action between the crushing roller and the tooth plate. However, when the ore samples are pressed, they are easily stuck in the gaps of the tooth plate. On the one hand, it is inconvenient to clean the ore samples stuck in the gaps of the tooth plate. On the other hand, the ore samples are likely to level the surface of the tooth plate, thereby affecting the subsequent crushing effect of the ore samples. Summary of the Invention

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, this embodiment provides a sample fragmentation device for geological and mineral exploration, including a support table 10, a material turning component 20, a crushing roller 30, a first driving component 40, a tooth plate component 50, and a second driving component 60. The lower end of the tooth plate component 50 is located below the support table 10, and the upper end passes through the support table 10 and extends above the support table 10. The crushing roller 30 is arranged on the upper part of the support table 10. The first driving component 40 is installed on the upper edge of the support table 10 and is used to drive the crushing roller 30 to reciprocate left and right along the upper part of the support table 10. When the crushing roller 30 moves to the left, it cooperates with the tooth plate component 50 to crush the ore sample. The second driving component 60 is installed on the lower part of the support table 10 and is used to drive the tooth plate component 50 to move up and down. The material turning component 20 is arranged on one side of the crushing roller 30. After the upper end of the tooth plate component 50 is removed from above the support table 10, the material turning component 20 is used to turn the ore sample on the upper part of the support table 10.

[0045] When it is necessary to crush and refine the ore sample, the ore sample to be refined can be placed on the upper part of the support table 10, and then the first driving component 40 is used to drive the crushing roller 30 to move to the left along the upper part of the support table 10. At this time, the crushing roller 30 cooperates with the tooth plate component 50 to perform a primary crushing treatment on the ore sample. When the crushing roller 30 moves to the leftmost position of the upper part of the support table 10, the first driving component 40 drives the crushing roller 30 to move to the right, and at the same time, the second driving component 60 drives the tooth plate component 50 to move downwards, so that the upper end of the tooth plate component 50 is removed from above the support table 10. When the crushing roller 30 moves to the right, it drives the material turning component 20 to move to the right synchronously. The material turning component 20 scrapes the ore sample that has been crushed once until the crushing roller 30 moves to the rightmost end of the upper part of the support table 10. Then the first driving component 40 drives the crushing roller 30 to move to the left again, and at the same time, the second driving component 60 drives the tooth plate component 50 to move upwards, so that the upper end of the tooth plate component 50 moves to above the support table 10 again, and then cooperates with the crushing roller 30 again to perform a secondary crushing on the turned ore sample. By repeating this cycle, the repeated crushing of the ore sample can be realized, and at the same time, the ore sample can be conveniently turned after each crushing, thereby improving the crushing and refining effect of the ore sample.

[0046] Please refer to Figure 1, in one embodiment, a support shaft 302 is rotatably arranged at the end of the crushing roller 30. The first driving assembly 40 includes a motor 401, a lead screw 402 and a sliding seat 403. The motor 401 is fixedly installed at the upper edge of the support table 10. The sliding seat 403 is fixedly arranged outside the support shaft 302. The bottom of the sliding seat 403 is slidably matched with the support table 10. One end of the lead screw 402 is connected to the output end of the motor 401, and the other end penetrates through the sliding seat 403 and is in threaded cooperation with the sliding seat 403.

[0047] After placing the ore sample to be refined on the upper part of the support table 10, the motor 401 drives the lead screw 402 to rotate forward. By the threaded cooperation of the lead screw 402 and the sliding seat 403, the sliding seat 403 is driven to slide leftward along the upper part of the support table 10. The sliding seat 403 drives the crushing roller 30 to move leftward through the support shaft 302. When the crushing roller 30 moves leftward, it cooperates with the tooth plate assembly 50 to crush the ore sample. When the crushing roller 20 moves to the leftmost end of the upper part of the support table 10, the motor 401 drives the lead screw 402 to rotate in the reverse direction. By the reverse threaded cooperation of the lead screw 402 and the sliding seat 403, the sliding seat 403 is driven to slide rightward along the upper part of the support table 10. The sliding seat 403 drives the crushing roller 30 to move rightward through the support shaft 302. At this time, the second driving assembly 60 drives the tooth plate assembly 50 to move downward, and the upper end of the tooth plate assembly 50 is removed from above the support table 10, so that the turning component 20 can conveniently turn the ore sample.

[0048] Please refer to Figure 1 , in one embodiment, a guide rail 104 is fixedly arranged at the upper edge of the support table 10. A guide rail groove (not shown in the figure) adapted to the guide rail 104 is formed at the bottom of the sliding seat 403.

[0049] Please refer to Figure 1 , in one embodiment, the turning component 20 includes a first support plate 201 and a plurality of scraping teeth 202. The first support plate 201 is arranged on one side of the crushing roller 30. A third support plate 203 is fixedly arranged on the side wall of the first support plate 201. One end of the third support plate 203 away from the first support plate 201 is connected to the support shaft 302. The plurality of scraping teeth 202 are fixedly arranged at one end of the first support plate 201 and are spaced apart along the length direction of the first support plate 201.

[0050] When the motor 401 drives the lead screw 402 to rotate in the reverse direction, thereby driving the crushing roller 30 to move rightward along the upper part of the support table 10, the support shaft 302 drives the first support plate 201 and several scraping teeth 202 to move rightward synchronously through the third support plate 203. During the rightward movement of the several scraping teeth 202, they act on the ore sample on the upper part of the support table 10, thereby turning the ore sample; moreover, when the motor 401 drives the lead screw 402 to rotate in the forward direction, thereby driving the crushing roller 30 to move leftward along the upper part of the support table 10, the crushing roller 30 drives the first support plate 201 and several scraping teeth 202 to move leftward synchronously through the third support plate 203. The first support plate 201 and several scraping teeth 202 can effectively block the ore sample that splashes due to the rolling of the crushing roller 30, avoiding the splashed ore sample from hurting the staff.

[0051] Please refer to Figure 1 、 Figure 3 and Figure 4 In one embodiment, several first crushing teeth 301 are fixedly arranged on the circumferential side wall of the crushing roller 30. The toothed plate assembly 50 includes a second support plate 501 and second crushing teeth 502. The second support plate 501 is arranged at the bottom of the support table 10. Several groups of the second crushing teeth 502 are provided. Several of the second crushing teeth 502 are fixedly arranged on the upper part of the second support plate 501. The upper ends of several of the second crushing teeth 502 pass through the support table 10 and extend above the support table 10.

[0052] When the motor 401 drives the lead screw 402 to rotate in the forward direction, thereby driving the crushing roller 30 to move leftward along the upper part of the support table 10, several first crushing teeth 301 on the circumferential side wall of the crushing roller 30 act on the ore sample, thereby crushing the ore sample by rolling, and cooperating with several second crushing teeth 502, so as to crush the ore sample by rolling.

[0053] Please refer to Figure 2 、 Figure 3 and Figure 7, in one embodiment, a guide rod 503 is fixedly arranged at the bottom of the second support plate 501, a bottom plate 101 is fixedly arranged at the bottom edge of the support table 10, a first support plate 105 and a second support plate 106 are fixedly arranged on the side wall of the bottom plate 101, the guide rod 503 vertically penetrates through the first support plate 105 and is movably matched with the first support plate 105, a U-shaped plate 304 is fixedly arranged at the end of the support shaft 302, the U-shaped plate 304 extends below the support table 10, a support rod 305 is fixedly arranged at the bottom of the U-shaped plate 304, a plurality of second bevel gear pieces 306 are hinged at the left and right ends of the bottom of the support rod 305, one side of each group of second bevel gear pieces 306 is connected to the support rod 305 through a group of second elastic members 307, and the second elastic members 307 are used to provide elastic support for the second bevel gear pieces 306. There are two sets of the second driving assemblies 60, and the two sets of the second driving assemblies 60 are respectively arranged at the left and right ends of the bottom of the second support plate 501. The two sets of the second driving assemblies 60 have the same structure and each includes a first connecting rod 601, a second connecting rod 602, a pin rod 603 and a gear disk 604. The gear disk 604 is rotatably arranged on one side of the second support plate 106. The upper end of the first connecting rod 601 is fixedly connected to the bottom of the second support plate 501, and the lower end is hinged to the second connecting rod 602. The pin rod 603 is fixedly arranged at an eccentric position on one side of the gear disk 604, and the lower end of the second connecting rod 602 is sleeved outside the pin rod 603 and is rotatably matched with the pin rod 603.

[0054] Initially, the crushing roller 30 is located at the upper right position of the support table 10. The first connecting rod 601 and the second connecting rod 602 are kept vertical, thereby providing support for the second support plate 501, so that the upper ends of several second crushing teeth 502 on the upper part of the second support plate 501 extend above the support table 10. When the motor 401 drives the lead screw 402 to rotate forward and then drives the crushing roller 30 to move to the left, several first crushing teeth 301 on the circumferential side wall of the crushing roller 30 act on the ore sample and cooperate with several second crushing teeth 502 to crush the ore sample by rolling. While the crushing roller 30 moves to the left, the U-shaped plate 304 and the support rod 305 can be driven by the support shaft 302 to move left synchronously. When the crushing roller 30 moves to the leftmost end of the upper part of the support table 10, the second bevel gear piece 306 at the bottom left end of the support rod 305 meshes with the left side gear disk 604, thereby driving the left side gear disk 604 to rotate. When the left side gear disk 604 rotates, the second connecting rod 602 is pulled by the pin rod 603, and then the first connecting rod 601 is pulled to make the second support plate 501 move downward. When the second support plate 501 moves downward, the guide rod 503 is driven, so that the guide rod 503 moves downward relative to the first support plate 105. At the same time, the second support plate 501 drives several second crushing teeth 502 on its upper part to move downward, so that the upper ends of several second crushing teeth 502 are removed from the position above the support table 10, thereby preventing several second crushing teeth 502 from protruding above the support table 10, ensuring that several scraping teeth 202 are not blocked by several second crushing teeth 502 during the subsequent rightward movement, and then smoothly turning the ore sample. At the same time, when several second crushing teeth 502 move downward, the ore sample can also be prevented from getting stuck between adjacent second crushing teeth 502, thereby causing the filling of the second crushing teeth 502, so as to improve the subsequent crushing effect of the ore sample; when the motor 401 drives the lead screw 402 to rotate reversely and then drives the crushing roller 30 to move to the right to the rightmost end position of the support table 10, several second bevel gear pieces 306 at the bottom right end of the support rod 305 mesh with the right side gear disk 604, thereby driving the right side gear disk 604 to rotate. When the right side gear disk 604 rotates, the second connecting rod 602 is pushed by the pin rod 603, and then the first connecting rod 601 is pushed to make the second support plate 501 move upward. The second support plate 501 drives several second crushing teeth 502 to move upward, so that the upper ends of several second crushing teeth 502 extend to the position above the support table 10 again, and then continue to cooperate with several first crushing teeth 301 to realize the continuous crushing of the ore sample during the subsequent leftward movement of the crushing roller 30.

[0055] Please refer to Figure 1 In one embodiment, a rectangular enclosure 102 is fixedly arranged on the upper part of the support table 10, and several of the second crushing teeth 502 are located in the inner area of the rectangular enclosure 102.

[0056] By setting the rectangular enclosure plate 102, the crushing and refinement process of the ore sample can be limited inside the rectangular enclosure plate 102, thereby preventing the ore sample from slipping out from the edge of the support table 10 when the crushing roller 30 moves and rolls over the ore sample.

[0057] During the process of the crushing roller 30 and several scraping teeth 202 moving leftward along the upper part of the support table 10, since the upper ends of several second crushing teeth 502 will extend above the support table 10, several second crushing teeth 502 will cause a great hindrance to the leftward movement of several scraping teeth 202. To avoid this phenomenon, please refer to Figure 1 and Figure 6 In one embodiment, one end of the third support plate 203 away from the first support plate 201 is sleeved outside the support shaft 302 and is rotationally matched with the support shaft 302. An external gear ring 303 is fixedly arranged on the side wall of the third support plate 203. At the upper left and right ends of the rectangular enclosure plate 102, several first helical teeth 103 are hinged. One side of each group of first helical teeth 103 is connected to the rectangular enclosure plate 102 through a group of first elastic members 107, and the first elastic members 107 are used to provide elastic support for the first helical teeth 103.

[0058] During the process of the crushing roller 30, the first support plate 201, and several scraping teeth 202 moving leftward along the upper part of the support table 10, the third support plate 203 is in an inclined posture, the first support plate 201 and several scraping teeth 202 are synchronously in an inclined posture, and several scraping teeth 202 do not contact the ore sample, so they will not turn the ore sample. Several second crushing teeth 502 will not affect the leftward movement of several scraping teeth 202. When the crushing roller 30 moves to the leftmost position of the upper part of the support table 10, the external gear ring 303 meshes with several first helical teeth 103 on the left side, thereby driving the third support plate 203 to rotate relative to the support shaft 302. When the third support plate 203 rotates, it drives the first support plate 201 and several scraping teeth 202 to rotate downward. Several scraping teeth 202 act on the upper surface of the support table 10, so that they can contact the ore sample to turn the ore sample during the subsequent rightward movement; when the crushing roller 30 moves to the rightmost end of the upper part of the support table 10, the external gear ring 303 meshes with several first helical teeth 103 on the right side, thereby driving the third support plate 203 to rotate in the opposite direction relative to the support shaft 302. When the third support plate 203 rotates in the opposite direction, it drives the first support plate 201 and several scraping teeth 202 to rotate upward, and several scraping teeth 202 rotate back to the inclined posture.

[0059] In one embodiment, the first elastic member 107 and the second elastic member 307 can be springs or metal elastic sheets, and there is no limitation here.

[0060] Please refer to Figure 5, in one embodiment, a chute 207 is formed on the first support plate 201. A scraping plate 206 is attached to one side of the first support plate 201. A connecting block 205 is fixedly arranged on the side wall of the scraping plate 206. One end of the connecting block 205 away from the scraping plate 206 passes through the chute 207 and is fixedly connected to a paddle 204.

[0061] After the ore sample has been crushed and refined multiple times, the staff can push the paddle 204, thereby driving the connecting block 205 to slide downward along the inside of the chute 207. The connecting block 205 drives the scraping plate 206 to move downward along the side wall of the first support plate 201. The scraping plate 206 moves down to one side of a plurality of scraping teeth 202, and then seals the gaps between the plurality of scraping teeth 202. When the crushing roller 30 moves to the right for a certain time, the scraping plate 206 can push the refined ore sample on the upper part of the support table 10 to push the refined ore sample away from the area where the plurality of second crushing teeth 502 are located, so as to facilitate the collection of the refined ore sample.

[0062] In the embodiment of the present invention, when it is necessary to crush and refine the ore sample, the ore sample to be refined can be placed on the upper part of the support table 10. Then, the first driving component 40 drives the crushing roller 30 to move leftward along the upper part of the support table 10. At this time, the crushing roller 30 cooperates with the tooth plate assembly 50 to perform a primary crushing process on the ore sample. When the crushing roller 30 moves to the leftmost position on the upper part of the support table 10, the first driving component 40 drives the crushing roller 30 to move rightward. At the same time, the second driving component 60 drives the tooth plate assembly 50 to move downward, so that the upper end of the tooth plate assembly 50 is removed from above the support table 10. When the crushing roller 30 moves rightward, it drives the turning component 20 to move rightward synchronously. The turning component 20 scrapes the ore sample that has been crushed once until the crushing roller 30 moves to the rightmost end of the upper part of the support table 10. The first driving component 40 drives the crushing roller 30 to move leftward again, and at the same time, the second driving component 60 drives the tooth plate assembly 50 to move upward, so that the upper end of the tooth plate assembly 50 moves above the support table 10 again, and then cooperates with the crushing roller 30 again to perform a secondary crushing on the turned ore sample. By repeating this cycle, the repeated crushing of the ore sample can be realized, and at the same time, the ore sample can be conveniently turned after each crushing, thereby improving the crushing and refining effect of the ore sample. Compared with the prior art, the ore sample can be repeatedly crushed and refined, and at the same time, during the refinement process of the ore sample, the ore sample can be effectively prevented from getting stuck in the gaps of the tooth plate assembly and then filling the tooth plate assembly, thereby improving the refinement effect and refinement efficiency of the ore sample.

[0063] The above has described the preferred embodiments of the present invention in detail, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
