[0002] The drilling and sorting separation of ore in field ore mining operation is a key link. The sampling link plays an extremely important role in the field of mining. Sampling of ore before mining can accurately evaluate the quality of mineral resources, analyze the composition and mineral composition, and provide basic data for mineral resource reserve estimation, ore mining and beneficiation process. The existing ore mining equipment has single function, and often needs multiple equipment to work together to complete a series of separate processes such as drilling, conveying, crushing and sorting. The equipment needs to be transported and closely connected, and the adaptability to complex field environment is poor. In addition, the multi-device collaborative operation not only increases the equipment purchase cost, but also improves the difficulty of transportation, installation operation and maintenance of single device, so that the field ore mining faces the problems of high cost, low efficiency and poor environmental adaptability. SUMMARY

The drilling, crushing and sampling are realized by the linear module; the ore samples are transported to the sorting system by the linear module and the transportation system; then the sorting of mineral fragments is realized by the vibrating screen sorting system, and finally the integrated sampling of ore drilling and sorting is realized. Specifically, the following steps are included:

[0004] Step 1 S1: move the mobile vehicle to the ore mining position, and then adjust the drilling assembly according to the operation requirement;

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Step S1: The mobile vehicle is moved to the ore extraction location, and then the drilling components are adjusted according to the operational requirements; Step S2: Drive the first mounting bracket to deflect on the mobile vehicle using a hydraulic cylinder to adjust the drilling angle; Step S3: Drive the scraper conveyor with an electric cylinder to deflect it on the connecting rod, thereby adjusting the angle of the scraper conveyor to match the angle of the drilling component. Step S4: Drive the second mounting bracket with a hydraulic cylinder, so that it slides along the guide rail via another set of sliders and drives the mounting seat, thereby adjusting the distance between the scraper conveyor and the drilling component, so that its input end is located at the position of the discharge inclined plate; Step S5: After the adjustment is completed, start the first linear module and drive the moving frame to move the support rod downward until the rubber support and the bottom of the conveying pipe contact the ground; then start the motor system, scraper conveyor, and gearbox system to drive the spiral blades on the rotating shaft and the drill bit to rotate. Step S6: Restart the linear module to move the helical blades and drill bit downwards. The drill bit drills out the mineral and conveys it upwards through the helical blades and conveying pipe to the discharge ramp. The mineral slides down the discharge ramp onto the scraper conveyor. Step S7: The scraper conveyor transports the minerals to the hopper. The motor and gearbox drive the crushing rollers to drop the crushed minerals onto the multi-stage screen plates. At the same time, the vibrating rotor on the connecting shaft rotates. Under the action of the vibrating rotor and the spring, the multi-stage screen plates in the screen box vibrate, realizing the vibration screening of the crushed minerals. Finally, the minerals slide along the multi-stage screen plates into the corresponding collection devices. Step S8: Remove the ore samples from the collection device and store them in separate bags.

[0032] In this embodiment, the operator drives the mobile vehicle 1 to the ore vein sampling point. Based on the ore vein inclination angle (approximately 30°) at the site, the second hydraulic cylinder 22 is activated to drive the first mounting frame 21 to deflect 30° on the mobile vehicle 1, so that the drill bit 213 of the drilling assembly 2 is aligned with the ore vein drilling position.

[0033] The electric cylinder 34 is activated, causing the scraper conveyor 33 to rotate synchronously by 30° on the connecting rod 32, ensuring that the input end of the scraper conveyor 33 matches the angle of the output end of the discharge ramp 27 of the drilling component 2. Simultaneously, the third hydraulic cylinder 36 pushes the mounting base 31, causing it to slide along the guide rail 12 via the slider 13, adjusting the output end of the scraper conveyor 33 to align with the input end of the funnel 42 of the crushing and sorting component 4. The buffer pad 35 cushions the contact area between the scraper conveyor 33 and the mounting base 31 to prevent collision damage. The first hydraulic cylinder 11 is activated, driving the second mounting frame 41 to slide along the guide rail 12 via another set of sliders 13. This, combined with the third hydraulic cylinder 36, fine-tunes the position of the mounting base 31, controlling the distance between the input end of the scraper conveyor 33 and the output end of the discharge ramp 27 within 10cm to prevent ore from falling.

[0034] The first linear module 25 is activated, driving the moving frame 23 and support rod 24 downwards until the rubber support 214 is in contact with the ground and the bottom of the conveying pipe 26 is close to the surface of the ore vein, thus completing the stable support of the equipment. Subsequently, the first motor 210, scraper conveyor 33, second motor 43 and third motor 49 are activated in sequence. The first motor 210 drives the first reduction gearbox 28 (using a gear reduction mechanism), which drives the rotating shaft 211 to rotate, and the spiral blade 212 and drill bit 213 rotate synchronously. The second linear module 29 is activated, which drives the first reduction gearbox 28 and drill bit to move slowly downwards at 0.1 m / s through the mounting plate 215. The drill bit 213 drills into the iron ore vein, and the spiral blade 212 conveys the drilled ore upwards along the conveying pipe 26 to the discharge inclined plate 27. The ore slides down the inclined plate onto the scraper conveyor 33, which then conveys it to the funnel 42.

[0035] The second motor 43 drives the second reduction gearbox 44 (using a worm gear reduction mechanism), which in turn drives the crushing roller 45 to rotate at high speed, crushing the ore falling into the funnel 42. The crushed ore particles fall onto the multi-stage screen plates 48 inside the screen box 46. After the third motor 49 starts, it drives the connecting shaft 413 to rotate through the first pulley 410, the synchronous belt 411, and the second pulley 412. The vibrating rotor 414 on the connecting shaft 413 rotates accordingly. Under the centrifugal force of the vibrating rotor 414 and the elasticity of the spring 47, the screen box 46 generates high-frequency vibration, and the multi-stage screen plates 48 (from top to bottom, they are 10 mesh, 20 mesh, and 40 mesh screen plates, all installed at an incline) vibrate synchronously. After sieving, coarse particles larger than 10 mesh slide down the top screen into the No. 1 collection box, medium particles of 10-20 mesh slide down the middle screen into the No. 2 collection box, and fine particles of 20-40 mesh slide down the bottom screen into the No. 3 collection box, thus completing the drilling, conveying, crushing, and grading screening of ore samples.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
