Description

Technical Field

[0001] The invention relates to the technical field of exploration sample crushing and sorting, and more specifically to a mineral geological exploration sample sorting device. Background Art

[0002] The mineral geological exploration sample sorting device is an indispensable equipment in geological exploration. When in use, the ore sample is fed into the device through the feed port. After being crushed by the crushing mechanism, the ore sample is crushed to a certain particle size. The crushed ore sample falls onto the screening mechanism. After being screened by the screening mechanism, the small particle samples and the large particle samples are separated. The small particle samples pass through the sieve holes and fall downward, while the large particle samples accumulate on the screening mechanism. For the large particle samples after screening, they can be re-sent into the device through the return port for further crushing and screening to improve the sample sorting rate.

[0003] However, different crushing mechanisms have different structural characteristics, working principles and performance parameters, and are suitable for ores of different hardness. Different geological exploration samples require different crushing and sorting devices due to their differences in composition, hardness and physical properties. A single type of mineral geological exploration sample sorting device has a single function. It is necessary to design a mineral geological exploration sample sorting device with two crushing functions that are suitable for higher hardness ores and lower hardness ores respectively.

[0055] Working principle: This embodiment provides a mineral geological exploration sample sorting device. When sorting high hardness geological exploration samples, insert the hexagonal wrench into the adjusting screw groove 84 and rotate it, and the adjusting circular shaft 83, the rotating shaft 82 and the screw 81 all rotate, so that the slider 73 slides relative to the slide groove 72 to the bottom end of the slide groove 72, and the crushing part 6 is formed as follows: Fig.12 In the eccentric crushing form shown in the figure, the crushing part 6 can rotate eccentrically relative to the straight barrel 471, and the crushing part 6 and the straight barrel 471 constitute a crushing structure. The geological exploration sample is fed into the crushing barrel 47 from the feed pipe 44. The output shaft of the motor 32 is controlled by the external control mechanism to rotate, which can drive the central gear 34 to rotate, so that the connecting shaft 35 drives the rotating block 71 to rotate, thereby causing the crushing mechanism 5 to rotate as a whole, and the rotation of the central gear 34 drives the planetary gear 38 to rotate, causing the inner gear ring 36 and the connecting ring 37 to rotate in the opposite direction relative to the central gear 34, causing the rotating ring 473 to rotate, and the entire crushing barrel 4 7 rotates accordingly, so that the geological exploration samples splashed into the gradient barrel 472 can more easily re-enter the straight barrel 471 under the action of centrifugal force. At this time, the crushing part 6 rotates eccentrically relative to the straight barrel 471 to crush the geological exploration samples. Under the suction of the negative pressure dust removal component, the crushed geological exploration samples in the cavity 43 can fall through the discharge pipe 481, among which some small-particle geological exploration samples pass through the sieve plate 483 and enter the negative pressure dust removal component, and the geological exploration samples of appropriate particle size cannot pass through the sieve plate 483 and continue to fall from the discharge pipe 481, and the geological exploration samples of appropriate particle size are collected;
