Technical Field

[0001] The utility model belongs to the technical field of rock grinders, and particularly relates to a rock composition analysis grinder. Background Technique

[0002] In the fields of geology, geochemistry, and mineral resource exploration, the composition analysis of rock samples is a crucial link. The composition analysis of rock samples not only helps us understand the structure and evolutionary history of the earth but also provides a scientific basis for the development and utilization of mineral resources.

[0003] Analyzing rocks requires grinding them into powder. However, existing grinding equipment is large in size, complex in operation, and has poor grinding effects. The samples ground out need to be screened additionally, and the coarse and fine rock powders need to be separated, which is rather cumbersome and increases the use cost.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figure 1 - Figure 2 As shown in the figure, a rock composition analysis grinder includes:

[0027] A box body 1, inside which a drawer 11 is movably installed, legs 12 are fixedly installed at the four corners of the bottom of the box body 1, a disk body 13 is fixedly installed at the top of the box body 1, and a frame body 14 is fixedly installed on the side of the disk body 13 away from the box body 1. The box body 1, the disk body 13, and the frame body 14 are internally interconnected;

[0028] A grinding assembly 2, which is arranged inside the frame body 14. The grinding assembly 2 includes two grinding rollers 21 movably installed inside the frame body 14, and two gears 22 are movably installed outside the frame body 14. The gears 22 are in shaft transmission connection with the shafts of the grinding rollers 21;

[0029] A screening assembly 3, which is arranged inside the disk body 13. The screening assembly 3 includes a sieve plate 31 movably installed inside the disk body 13, a rotating shaft 35 is movably installed on one side of the sieve plate 31, and a plurality of cams 36 are fixedly installed on the outside of the rotating shaft 35.

[0030] Specifically, two grinding rollers 21 are symmetrically arranged. On both sides of the outer part of the frame 14 near the axis of the grinding roller 21, gears 22 are movably installed. The gears 22 are in shaft transmission connection with the grinding roller 21, and the gears 22 are meshed with each other. On one side of the gears 22, driven belt pulleys 23 are in transmission connection. On the outer part of the frame 14 near the gears 22, a first servo motor 24 is installed through a fixed seat. The output end of the first servo motor 24 is in transmission connection with a driving belt pulley 25 through a coupling. A belt 26 is connected between the driving belt pulley 25 and the driven belt pulley 23.

[0031] As can be seen from the above, two grinding rollers 21 are arranged inside the frame 14, and the grinding rollers 21 are used to grind the rock. Through the cooperation of the driving belt pulley 25, the driven belt pulley 23 and the belt 26, the first servo motor 24 can synchronously drive the two gears 22 to rotate, and then drive the grinding rollers 21 to rotate, achieving the grinding effect. This structure is simple to operate and the equipment has a small volume, which can effectively improve the grinding efficiency. During specific use, first start the first servo motor 24 to drive the driving belt pulley 25 to rotate, and then the driving belt pulley 25 drives the driven belt pulley 23 to rotate through the belt 26, and then drives the two gears 22 to drive the grinding rollers 21 to rotate. Then the rock can be put into the frame 14.

[0032] Embodiment 2:

[0033] Please refer to Figure 1 and Figure 3 - Figure 5 As shown, a sieve plate 31 is movably installed inside the disk body 13. The sieve plate 31 is in sliding fit with the inner wall of the disk body 13. Two support plates 32 are fixedly installed inside the disk body 13. The two support plates 32 are arranged below the sieve plate 31. The two support plates 32 are symmetrically arranged. Limiting rods 33 are fixedly installed at the tops of the two support plates 32. A return spring 34 is connected between the sieve plate 31 and the support plates 32. The return spring 34 is arranged outside the limiting rods 33.

[0034] Specifically, a rotating shaft 35 is movably installed inside the disk body 13 near the sieve plate 31 through a bearing. The rotating shaft 35 is arranged below the sieve plate 31. A plurality of cams 36 are fixedly installed on the outer side of the rotating shaft 35. A second servo motor 37 is installed on the outer part of the disk body 13 near the rotating shaft 35 through a fixed seat. The output end of the second servo motor 37 is in shaft transmission connection with the rotating shaft 35 through a coupling.

[0035] As can be seen from the above, a movable sieve plate 31 is arranged inside the disk body 13. The sieve plate 31 is used to distinguish the ground rock powder into thick and fine parts. Only the finer rock powder can pass through the sieve plate 31, thus avoiding manual screening, saving operation steps, having lower costs, and the sieve plate 31 can vibrate up and down under the action of the cam 36 and the return spring 34 to improve the feeding speed of the rock powder. The rock powder that passes through the screening will fall into the drawer 11, which is convenient for collection and analysis.

[0036] During specific use, first start the second servo motor 37 to drive the rotation of the rotating shaft 35. The rotating shaft 35 will drive the rotation of the cam 36. During the rotation of the cam 36, it will repeatedly push the sieve plate 31 to move upward. After the sieve plate 31 moves upward, it will be reset under the action of the return spring 34, thus realizing the effect of the sieve plate 31 vibrating up and down and improving the feeding speed.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
