The specific technical solution is as follows:

[0006] A crushing device for mineral exploration samples includes a crushing chamber. The top of the crushing chamber is communicated with a feeding port.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the present utility model in conjunction with specific implementation cases and the attached Figures 1 to 4 drawings, but the present utility model is not limited to these embodiments.

[0026] Refer toFigures 1 to 4 As shown in the figure, a crushing device for mineral exploration samples includes a crushing chamber 1. The top of the crushing chamber 1 is connected to a feeding port 2. The ore samples to be crushed are put into the inner cavity of the crushing chamber 1 through the feeding port 2. A first rotating shaft 3 is rotatably installed in the inner cavity of the feeding port 2 through a bearing. A guide plate 4 is installed on the outer wall of the first rotating shaft 3. By adjusting the rotation of the first rotating shaft 3, the guide plate 4 can be driven to rotate. The guide plate 4 blocks one side of the feeding port 2, prompting the mineral samples to enter the inner cavity of the crushing chamber 1 through the other side of the feeding port 2. A housing 5 is installed on the front side wall of the feeding port 2. The front end of the first rotating shaft 3 extends into the inner cavity of the housing 5 and is rotatably connected to the inner wall of the housing 5 through a bearing. A first gear 6 is installed on the outer wall of the front end of the first rotating shaft 3. A rack 7 is meshed with the outer wall of the first gear 6. By driving the movement of the rack 7, the first gear 6 is driven to rotate, and then the first rotating shaft 3 is prompted to rotate. A moving block 8 is vertically installed at the top of the rack 7. A cylinder 9 is installed in the inner cavity of the housing 5. The cylinder 9 is a self-locking cylinder, which is a commonly used cylinder type on the market. Its output end can stay at any position and be locked. There is no need to elaborate on this here. The output end of the cylinder 9 is connected to the outer wall of the moving block 8. By driving the movement of the moving block 8 by the cylinder 9, the rack 7 is prompted to move, realizing the rotation of the first gear 6 driving the first rotating shaft 3. A limiting rod 10 is installed horizontally in the inner cavity of the housing 5, and the moving block 8 is slidably sleeved on the outer wall of the limiting rod 10. When the moving block 8 moves, it can slide along the outer wall of the limiting rod 10 to limit the moving direction of the moving block 8, thereby ensuring the stable movement of the rack 7.

[0027] Refer to Figure 3 As shown in the figure, a fixed seat 11 is installed in the middle of the inner cavity of the crushing chamber 1. The fixed seat 11 and the inner side wall of the crushing chamber 1 form two channels on the left and right. The mineral samples after being dispersed and guided from the top can enter the two channels successively and separately, so as to carry out subsequent crushing processing separately later; Second crushing plates 18 are respectively installed on the inner walls of the two channels of the crushing chamber 1. A first crushing plate 17 corresponding to the position of the second crushing plate 18 is movably arranged in the inner cavity of the fixed seat 11. After the mineral samples enter the channels, they can be crushed in cooperation with the second crushing plates 18 under the reciprocating action of the first crushing plate 17.

[0028] Specifically refer to Figure 4As shown, at the bottom end of the inner wall of the fixed seat 11, a mounting plate 14 is vertically installed. A moving rod 15 penetrates through the outer wall of the mounting plate 14. A spring 16 is sleeved on the outer wall of the moving rod 15. The end of the moving rod 15 is connected to the side wall of the first crushing plate 17. When the first crushing plate 17 moves, it can cause the moving rod 15 to move along the outer wall of the mounting plate 14. The two ends of the spring 16 are respectively connected to the outer wall of the mounting plate 14 and the outer wall of the first crushing plate 17. When the first crushing plate 17 approaches the second crushing plate 18, it can clamp and crush the mineral sample between the first crushing plate 17 and the second crushing plate 18. At this time, the spring 16 is stretched, and the moving rod 15 moves along the outer wall of the mounting plate 14. Two second rotating shafts 12 are rotatably arranged in the inner cavity of the fixed seat 11 from front to back through bearings. An eccentric cam 13 is installed on the outer wall of the second rotating shaft 12, and the cam 13 rotates and fits against the side wall of the first crushing plate 17. When the second rotating shaft 12 rotates, it drives the cam 13 on the outer wall to rotate. When the cam 13 rotates to the side where the eccentricity is far from the first crushing plate 17 and fits against the side wall of the first crushing plate 17, it causes the first crushing plate 17 to approach the second crushing plate 18 to clamp and crush the mineral sample between the first crushing plate 17 and the second crushing plate 18. When the cam 13 rotates to the side where the eccentricity is close to the first crushing plate 17 and fits against the side wall of the first crushing plate 17, under the elastic force of the spring 16, it causes the first crushing plate 17 to move away from the second crushing plate 18 and causes the moving rod 15 to move reversely along the mounting plate 14 for resetting. In this way, the first crushing plates 17 and the second crushing plates 18 on the left and right sides synchronously crush the mineral samples in their respective channels.

[0029] Refer to Figure 1 and Figure 3 As shown, the front ends of the two second rotating shafts 12 respectively extend out of the outer wall of the crushing chamber 1 and are installed with second gears 20. The two second gears 20 are meshed and connected. A motor 21 is installed on the front side wall of the crushing chamber 1, and the output end of the motor 21 is connected to one of the second rotating shafts 12. By starting the motor 21, the second rotating shaft 12 on the left side is driven to rotate, so as to drive the second gear 20 on the left side to drive the second gear 20 on the right side to rotate synchronously. The second gear 20 on the right side drives the second rotating shaft 12 on the right side to rotate. Thus, the two second rotating shafts 12 on the left and right sides rotate simultaneously.

[0030] In addition, refer to Figure 3 As shown, discharge channels 19 are respectively opened at the bottom ends of the two channels formed by the fixed seat 11 and the inner side wall of the crushing chamber 1. A discharge port 22 is arranged at the bottom end of the crushing chamber 1, and the discharge channels 19 are communicated with the inner cavity of the discharge port 22. The mineral samples crushed by the first crushing plate 17 and the second crushing plate 18 can enter the discharge port 22 through the discharge channels 19 and be discharged and collected.

[0031] In order to leave enough space for collecting materials discharged at the discharge port 22, support columns 23 are vertically installed at the four corners at the bottom end of the crushing bin 1. While providing support force for the whole equipment, the support columns 23 can also lift the crushing bin 1 off the ground, leaving enough distance from the ground for subsequent discharge collection.

[0032] The working principle of a mineral exploration sample crushing device in this embodiment is as follows:

[0033] By driving the moving block 8 and the rack 7 to move through the activated cylinder 9, the first gear 6 meshed with the outer wall is driven to rotate by the rack 7, thereby promoting the rotation of the first rotating shaft 3. The first rotating shaft 3 drives the guide plate 4 installed on the outer wall to rotate, so as to adjust the position of the guide plate 4; the guide plate 4 in the left-tilted state causes the mineral samples to enter the right inner cavity of the crushing bin 1 along the surface of the guide plate 4, and the guide plate 4 in the right-tilted state causes the mineral samples to enter the left inner cavity of the crushing bin 1 along the surface of the guide plate 4, thereby realizing the dispersed feeding of the mineral samples into the left and right inner cavities of the crushing bin 1;

[0034] By means of the activated motor 21, the second rotating shaft 12 on the left side is driven to rotate, so as to drive the second gear 20 on the left side to drive the second gear 20 on the right side to rotate synchronously. The second gear 20 on the right side drives the second rotating shaft 12 on the right side to rotate, thereby realizing the simultaneous rotation of the two second rotating shafts 12 on the left and right sides. When the cam 13 rotates to the eccentric side and abuts against the side wall of the first crushing plate 17, the first crushing plate 17 is urged to approach the second crushing plate 18, so as to clamp and crush the mineral samples between the first crushing plate 17 and the second crushing plate 18, and the spring 16 is stretched, and the moving rod 15 moves along the outer wall of the mounting plate 14; when the cam 13 rotates to the centric side and abuts against the side wall of the first crushing plate 17, under the elastic force of the spring 16, the first crushing plate 17 is urged to move away from the second crushing plate 18, and the moving rod 15 moves along the mounting plate 14 in the reverse direction to reset. In this way, the first crushing plates 17 and the second crushing plates 18 on the left and right sides synchronously crush the mineral samples in their respective channels; the mineral samples crushed by the first crushing plate 17 and the second crushing plate 18 can enter the discharge port 22 through the blanking channel 19 for discharge and collection;

[0035] The utility model disperses and guides the feeding of mineral samples, effectively avoiding the accumulation of samples, enabling the mineral samples to be dispersed and directly contact the first crushing plate 17 and the second crushing plate 18, realizing the rapid, effective and complete crushing of the samples. Using the same driving force, the crushing effects of the left and right channels are carried out synchronously, saving the driving force and the crushing time, and thus shortening the overall crushing time required for the mineral samples.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
