[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-3 As shown, a geological sample crushing device includes a crushing box 1 supported on the ground by supporting legs 2.

[0033] A crushing assembly 4 is arranged inside the crushing box 1, and the crushing assembly 4 includes a hollow cylinder 9, a beating roller 13 and an impact plate 14. The hollow cylinder 9 is rotatably connected to the lower surface of the top of the crushing box 1, and a plurality of avoidance grooves 8 are opened on the inner wall of the hollow cylinder 9. The beating roller 13 is rotatably connected to the crushing box 1 and the inner wall of the hollow cylinder 9 through a transmission shaft 12. A plurality of radially arranged beating plates are fixedly connected to the outer wall of the beating roller 13. The impact plate 14 is fixedly connected to the inner wall of the crushing box 1, and a fixing frame 5 is fixedly connected to the inner wall of the crushing box 1 located at the bottom of the hollow cylinder 9 and the beating roller 13. The fixing frame 5 has a built-in driving assembly for driving the hollow cylinder 9 and the beating roller 13 to rotate.

[0034] When the geological sample enters the crushing box 1, it will first reach between the hollow cylinder 9 and the beating roller 13, and then the driving component will drive the hollow cylinder 9, the beating roller 13 and the beating plate to rotate. The beating plate will beat the geological sample for preliminary crushing. Under the action of centrifugal force, the geological sample will fly out of the avoidance groove 8 and hit the impact plate 14 to be crushed again, and the sample after the impact will rebound, thereby colliding with the remaining geological samples for further crushing.

[0035] The device is provided with a hollow cylinder 9 and a beating roller 13. When a geological sample enters between the hollow cylinder 9 and the beating roller 13, the beating roller 13 drives the beating plate to rotate to beat the geological sample to achieve crushing, thereby avoiding the defect of being unable to process large geological samples.

[0036] like Figure 2 As shown, a feed hopper 3 is fixedly installed on the top of the crushing box 1, and a discharge port 7 is opened on the inner wall of the bottom of the crushing box 1.

[0037] The geological sample enters the crushing box 1 through the feed hopper 3 , and the sample that meets the requirements after being crushed is finally discharged through the discharge port 7 .

[0038] like Figure 3 As shown, the inner wall of the crushing box 1 located at the bottom of the fixed frame 5 is fixed with filter plate 10 and filter plate 2 11 in sequence, the filter plate 10 and filter plate 2 11 are arranged tilted and the tilting directions are opposite, and the outer walls on both sides of the crushing box 1 are provided with discharge grooves that cooperate with the filter plate 10 and the filter plate 2 11.

[0039] The geological samples crushed by the crushing assembly 4 are filtered by filter plate 1 10 and filter plate 2 11 in layers and finally discharged through the discharge port 7, and the geological samples not filtered out are discharged through the discharge trough.

[0040] like Figure 3 and Figure 4 As shown, the driving assembly includes a connecting plate 15, an inner gear ring 16 and a motor 18. The connecting plate 15 is fixedly connected to the bottom of the hollow cylinder 9. The bottom of the connecting plate 15 is rotatably connected to a gear 17 via a rotating shaft. The inner gear ring 16 is fixedly connected to the inner wall of the fixed frame 5. The outer wall of the transmission shaft 12 is fixedly connected to a gear 2 19. The gear 17 is meshed with the inner gear ring 16 and the opposite side of the gear 2 19.

[0041] The motor 18 is fixed to the lower surface of the bottom of the fixing frame 5 by bolts, and the output shaft of the motor 18 is fixedly connected to one end of the transmission shaft 12 by a coupling.

[0042] Starting motor 18 drives transmission shaft 12 to drive gear 2 19 and beating roller 13 to rotate, so that gear 17 rotates on itself while revolving along the outer wall of gear 2 19, thereby driving hollow cylinder 9 to rotate. The revolution speed of gear 17 is lower than the rotation speed of gear 2 19, so that hollow cylinder 9 and beating roller 13 rotate in the same direction but at different speeds. Therefore, the geological sample thrown out has a different rotation speed from hollow cylinder 9 and will also collide with hollow cylinder 9.

[0043] The device is provided with an inner gear ring 16, gear one 17 and gear two 19. When the motor one 18 drives the transmission shaft one 12 to drive the gear two 19 to rotate, the hollow cylinder 9 and the beating roller 13 can rotate in the same direction but at different speeds, so that the geological sample thrown out will collide with the hollow cylinder 9 and be crushed. Then the sample flies out from the avoidance groove 8 and collides with the impact plate 14, and is rebounded by the impact plate 14, so as to collide with the remaining flying samples to be crushed again. After multiple crushing, the impact force is strengthened, thereby improving the fragmentation effect of the geological sample.

[0044] In this embodiment: when in use, the geological sample is introduced into the crushing box 1 through the feed hopper 3, and the sample will first enter between the hollow cylinder 9 and the beating roller 13 through the notch at the top of the hollow cylinder 9. The hollow cylinder 9 and the beating roller 13 rotate in the same direction but at different speeds with the cooperation of the inner ring gear 16, gear one 17 and gear two 19, so that the beating roller 13 drives the beating plate to perform preliminary beating and crushing on the sample. At the same time, since the sample thrown out by the beating plate has a different rotation speed from the hollow cylinder 9, it will collide with the hollow cylinder 9 to achieve secondary crushing. Then the sample flies out through the avoidance groove 8 and collides with the impact plate 14 to achieve re-crushing. At the same time, the sample is rebounded by the impact plate 14 and collides with the remaining samples to further achieve impact crushing. After multiple impact crushing, the sample will fall downward under the action of gravity. After screening by filter plate one 10 and filter plate two 11, qualified samples will be discharged through the discharge port 7, and unqualified samples will be discharged through the discharge trough.

[0047] A dust collecting assembly 6 is disposed on an outer wall of one side of the crushing box 1 , and the dust collecting assembly 6 includes a shell 20 , fan blades 22 and a dust collecting box 23 .

[0048] The shell 20 is fixed to the outer wall of the crushing box 1 by bolts, and the inner wall of the crushing box 1 is provided with a through groove connected to the shell 20, the fan blades 22 are rotatably connected to the inner wall of the shell 20 through the second transmission shaft 21, and the outer wall of one side of the shell 20 is fixed with a second motor 24 by bolts, and the output shaft of the second motor 24 is fixedly connected to the second transmission shaft 21 through a coupling.

[0049] The dust box 23 is detachably mounted on the outer wall of the crushing box 1 , and the shell 20 and the dust box 23 are connected via a pipeline.

[0050] In this embodiment: the second starter motor 24 drives the second transmission shaft 21 to drive the fan blades 22 to rotate, so as to absorb the dust generated in the crushing box 1 and transport it to the dust collecting box 23 through the pipeline for unified collection.

[0051] The device is provided with fan blades 22 and a dust box 23, and uses a motor 24 to drive a transmission shaft 21 to drive the fan blades 22 to rotate, so that the dust generated in the crushing box 1 can be absorbed and uniformly collected in the dust box 23 for subsequent processing, thereby improving the working environment.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
