Description

Technical Field

[0001] The invention belongs to the technical field of mineral crushing, and in particular relates to a mechanical-hydraulic composite crushing and collecting device for underwater minerals and a use method thereof. Background Art

[0002] There are abundant mineral resources underwater. The reserves of rare metals such as cobalt, manganese and nickel far exceed those on land. These resources are vital to modern industry and high-tech industries. Especially with the increasing depletion of land resources, the development of underwater resources has become increasingly important. Compared with land mining, underwater mining has less impact on the environment. Underwater mining does not require the construction of a large amount of infrastructure, thus reducing damage to the surface environment.

[0003] Traditional underwater mining equipment generally uses mechanical crushing to crush large ores so that they can be pumped back to the ship. However, the mined ore cannot be fully granulated through only one process of mechanical crushing, which will cause some large pieces of minerals to be unable to be smoothly pumped back to the ship, affecting the efficiency of mineral mining.

[0023] S3 Mineral Collection: After three crushings, the mineral particles fall through the sieve holes on the receiving plate onto the second conveyor belt, and then the recovery pipe on the underwater mining vehicle uses a pump to pump the mineral particles back to the mining ship on the water surface.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The present invention provides a conveying mechanism with a first conveyor belt and a falling inclined plate. When underwater mining operations are required, the device can be installed on an underwater mining vehicle. The first conveyor belt and the falling inclined plate convey the ore to the crushing mechanism. The mechanical crushing assembly with a fixed crushing arm and a movable crushing roller and the hydraulic crushing assembly driving the jet pump and the hydraulic crushing output end can crush the conveyed ore into particles. In addition, since a cam is installed on the second roller and the cam contacts the bottom of the receiving plate, when the second driving motor drives the second roller to rotate, it can also drive the cam to rotate. Then, the cam can intermittently lift the receiving plate, so that the receiving plate can continuously shake the ore. The high-pressure water flow can evenly crush the shaken stones, thereby preventing the conveyed stones from piling up and causing the hydraulic equipment to crush the stones incompletely.

[0026] (2) The present invention provides a movable crushing roller with a first gear and a second gear with a first rotating roller, wherein the first rotating roller is movably installed on the inner wall of the mining vehicle, so as to provide a positioning measure for the first rotating roller. When the second driving motor is started, the first belt can simultaneously drive the first rotating roller and the second rotating roller to rotate, so as to ensure that the crushing work and the shaking work are carried out simultaneously. By providing a crawler-type underwater traveling mining vehicle, the drill bit provided at the front end of the vehicle is used to crush large minerals, and then the large ores are transported into the vehicle. The movable crushing roller and the fixed crushing arm in the vehicle are used to crush the ores for the second time. The crushed ore will fall onto the receiving plate, and the jet pump is used to suck in the external water, and then the water is ejected through the mesh plate by high pressure. The high-pressure water flow is used to crush the stones into particles, which are convenient for pumping back to the ship.

[0027] (3) The present invention sets a water drainage pipe with a filter bin. Since the present device is used for underwater mining and adopts a pumping hydraulic crushing method, during the pumping process, the water drainage pipe will extract some plankton and garbage and other impurities in the water into the device. These impurities are mixed with mineral particles and are difficult to screen and process. The present device sets a first connecting roller on the connecting shaft on one side of the movable crushing roller. When the first rotating roller drives the connecting shaft to rotate, the first connecting roller on the connecting shaft drives the second connecting roller in the extraction bin to rotate through the second belt, thereby driving the extraction impeller to perform a rotational extraction operation, thereby extracting the impurities accumulated in the filter into the extraction bin and then discharging them from the filter residue discharge bin to the outside.

[0028] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
