Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of geological exploration, more particularly, it relates to a sandstone type copper ore prospecting device. BACKGROUND
[0002] As an important raw material, the exploration and development technology of copper ore is increasingly valued. Among various types of copper ore, sandstone type copper ore has become the focus of exploration due to its abundant reserves, wide distribution and relatively low mining cost. However, in the current sandstone type copper ore exploration technology, the conventional prospecting device mainly relies on motor-driven drilling pipes for stratum drilling and sampling. This traditional method has certain drawbacks when facing complex geological conditions: when the drilling pipe encounters hard soil layer, gravel layer or well-cemented sandstone layer, the frictional resistance between the drill bit and the stratum increases suddenly, resulting in frequent sticking of the drilling pipe. This sticking not only increases the motor load and power consumption, but also reduces the drilling speed, affecting the prospecting progress. In addition, the motor is prone to overheating and damage under overload operation, leading to frequent equipment maintenance.
[0003] This series of technical problems caused by excessive motor load will affect the entire exploration workflow and economic benefits. First, the frequent sticking during drilling reduces the core quality, directly affecting the accuracy and continuity of geological information and increasing the uncertainty of ore prospecting. Second, the large fluctuation of motor load leads to low energy utilization efficiency. Third, the existing device requires high technical requirements for operators, and rich field experience is needed to judge and handle the sticking situation, which further exacerbates the labor problem in the talent-shortage exploration industry. Fourth, the frequent maintenance and replacement of parts of the drilling device prolongs the exploration period and indirectly increases the exploration investment. SUMMARY

[0017] (Three) beneficial effects
[0018] Compared with the prior art, the sandstone type copper ore prospecting device provided by the application has the following beneficial effects: the sandstone type copper ore prospecting device is designed through the anti-overload mechanism, solves the problem that the traditional prospecting device causes the motor to be overloaded due to the jamming of the drilling pipe under complex geological conditions, realizes the improvement of the efficiency and reliability of the prospecting operation, adopts the double tripod structure and the guide rod slide system, provides a stable and reliable support platform for the drilling operation, ensures the perpendicularity control in the drilling process, effectively avoids the drilling deviation caused by the shaking or tilting of the equipment, and improves the core quality and the accuracy of the geological data.
[0019] The anti-overload mechanism of the device uses the principle of sun gear and planetary gear transmission system. When the drilling resistance is within the normal range, the sun gear can drive the entire anti-overload mechanism to rotate synchronously, which not only ensures the drilling efficiency, but also enhances the rock breaking capacity of the drill bit through the inertial force generated by the overall rotation, and improves the drilling penetration. When the drilling resistance increases due to hard stratum, the anti-overload mechanism can automatically start the protection function, and through the differential transmission of the large planetary gear and the small planetary gear, the relative sliding mechanism between the friction plate and the inner and outer friction racks is activated, so that the mounting frame and the drilling pipe stop rotating, thereby effectively protecting the motor from overload damage. This self-adaptive protection system effectively avoids the motor burnout and transmission system damage caused by the drill bit sticking in the traditional device.
[0020] The multi-layer friction system composed of the friction plate and the inner and outer friction racks not only provides adjustable friction resistance control, but also realizes uniform distribution and transmission of load. The operator can set the friction resistance threshold value through the bolt and nut system according to different geological conditions and drilling requirements, so that the device can adapt to geological environments from loose sand to hard cemented sandstone, thereby enhancing the versatility and adaptability of the device. The anti-loosening design of the magnetic block and the clamping block ensures the stability of the friction resistance setting, avoids accidental adjustment in long-term vibration operation environment, and ensures the consistency and reliability of the protection parameters.
[0021] The device realizes independent operation of drilling depth control and rotating drilling through the design of a dual-motor driving system. The first motor is responsible for driving the carriage to move up and down to control the drilling depth, and the second motor is specifically used to drive the sun gear to rotate the drilling pipe. This separated control not only improves the operation accuracy, but also reduces the working load of the single motor, prolongs the service life of the equipment, and reduces the equipment maintenance cost and replacement frequency, thereby reducing the downtime and maintenance cost. Overall, this sandstone type copper ore prospecting device improves the exploration efficiency, reduces the operation cost, protects the equipment safety, and enhances the environmental adaptability through the anti-overload mechanism design.

[0038] When the ore prospecting device is used, the whole device is placed to the target position, three groups of supports 15 are in contact with the ground support, the sampling position is determined, the first motor 17 and the second motor 110 are started, the first motor 17 drives the driving gear 18 to rotate, because the driving gear 18 is in mesh with the driving rack 16, so the rotation of the driving gear 18 drives the sliding frame 14 to move downward along the guide rod 13, at the same time, the second motor 110 drives the sun gear 19 to rotate, in the normal state, the sun gear 19 drives the whole anti-overload mechanism to rotate synchronously, the drilling pipe 27 connected with the lower end surface of the connecting plate 26 rotates synchronously, and the drilling sampling work is carried out, when the sun gear 19 drives the whole anti-overload mechanism to rotate, the inertia force is also generated, which is more helpful for the drilling sampling work; when the drilling pipe 27 encounters hard soil layer, gravel layer or well-cemented sandstone layer, the frictional resistance between the drill bit and the stratum increases suddenly, at this time, the second motor 110 still drives the sun gear 19 to rotate, but a plurality of groups of large planetary gears 28 meshed with the sun gear 19 start to rotate, the large planetary gears 28 drive the intermediate small planetary gears 29 to rotate synchronously, the rotation of the small planetary gears 29 drives the double-sided gear 213 meshed with the small planetary gears 29 to rotate, the rotation of the double-sided gear 213 drives the first follower gear 211 meshed with the other side of the double-sided gear 213 to rotate, the rotation of the first follower gear 211 drives the second follower gear 212 at both ends and the second follower gear 212 to rotate, the second follower gear 212 drives the inner friction rack 215 and the outer friction rack 216 to rotate in the opposite direction by overcoming the friction force of the friction plate 214, and the anti-overload purpose is achieved.
