[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Reference Figure 1 - Figure 7 As shown, the present invention provides a drum ore washer for mining, comprising a box body 1, a mounting frame 21 is fixedly connected to the front end of the box body 1, a feed hopper 22 is fixedly installed on the top of the mounting frame 21, a connecting rod 27 is symmetrically installed on the rear side of the feed hopper 22, one end of the connecting rod 27 is fixedly connected to the top of the front end of the box body 1, and the box body 1 comprises a feeding mechanism 2 for feeding, a tumbling mechanism 4 for tumbling, a water spraying mechanism 5 for spraying water, a filtering mechanism 6 for filtering and a stirring mechanism 7 for stirring;

[0036] A double-axis motor 3 is fixedly installed on the middle horizontal plate of the mounting frame 21, an eccentric wheel 23 is fixedly sleeved on the output shaft at one end of the double-axis motor 3, a linkage rod 24 is movably sleeved on the protrusion of the eccentric wheel 23, a connecting block 25 is movably connected to the top notch of the linkage rod 24, one end of the connecting block 25 passes through the side wall of the feed hopper 22 and is fixedly connected to a shaking plate 26, and the bottom end of the shaking plate 26 is movably connected to the inner wall of the feed hopper 22 at the inclined position.

[0037] In this embodiment, when washing ore, the dual-axis motor 3 is started, and the output shaft at one end thereof drives the eccentric wheel 23 to rotate. The linkage rod 24 sleeved on the protrusion of the eccentric wheel 23 moves up and down with the rotation of the eccentric wheel 23. The linkage rod 24 drives the connecting block 25 to move up and down. When the connecting block 25 moves up and down, it drives the shaking plate 26 to shake up and down on the inner wall of the feed hopper 22, so that the ore can pass through the feed hopper 22 smoothly and evenly into the interior of the filter cylinder 43, effectively preventing the ore from being blocked during the feeding process.

[0038] In a further embodiment, a pinion 41 is fixedly sleeved on the output shaft at the other end of the dual-axis motor 3, a gear ring 42 is meshingly installed on the outer surface of the pinion 41, the gear ring 42 is fixedly sleeved on the front end convex tube of the filter cartridge 43, and the front end convex tube of the filter cartridge 43 is embedded in the rear side groove of the feed hopper 22.

[0039] In this embodiment, while the dual-axis motor 3 provides power for the feeding mechanism 2, the output shaft at the other end of the dual-axis motor 3 drives the pinion 41 to rotate, and the pinion 41 drives the gear ring 42 to rotate, thereby causing the filter barrel 43 to rotate, so that the ore is continuously turned over in the filter barrel 43. This design does not require the configuration of multiple motors to drive different mechanisms respectively, reducing the space occupied by the equipment and the cost investment. On the one hand, it effectively prevents the ore from being blocked during the feeding process, thereby improving the ore washing effect and the service life of the equipment. On the other hand, the ore can be more fully exposed to the water sprayed by the water spraying mechanism 5, ensuring that each ore surface can be fully rinsed, thereby improving the uniformity and thoroughness of the cleaning.

[0040] In a further embodiment, a water pump 51 is fixedly installed on one side of the top of the box body 1, a water pump 52 is fixedly sleeved on the input end of the water pump 51, the bottom end of the water pump 52 is fixedly sleeved on one side of the water storage tank 53, a water delivery pipe 54 is fixedly sleeved on the output end of the water pump 51, a rotating joint 55 is fixedly sleeved on the bottom end of the water delivery pipe 54, one end of the rotating joint 55 is rotatably connected to a diversion pipe 56, a plurality of stirring pipes 57 are fixedly sleeved on the outer surface of the diversion pipe 56, and a plurality of nozzles 58 are fixedly connected to the outer surfaces of the plurality of stirring pipes 57.

[0041] In this embodiment, after the mineral material enters the filter cartridge 43, the water pump 51 is started, and the water pump 51 draws water from the water tank 53 through the pumping pipe 52, and then transports the water through the water pipe 54. The water pipe 54 transmits the water to the rotary joint 55, and the diversion pipe 56 evenly distributes the water to several stirring tubes 57, and finally sprays it out from the nozzle 58, impacting the surface of the ore, making it easier to wash away the impurities on the surface of the ore, thereby improving the cleaning effect.

[0042] In a further embodiment, a sewage pipe 61 is fixedly connected to the bottom end of the box body 1, one end of the sewage pipe 61 is fixedly connected to a sedimentation box 62, a mud cleaning door 65 is movably connected to the bottom of one side of the sedimentation box 62, a filter tube 63 is fixedly sleeved on the top of the rear side of the sedimentation box 62, a filter screen 64 is fixedly installed on the inner wall of one end of the filter tube 63 close to the sedimentation box 62, and one end of the filter tube 63 away from the sedimentation box 62 is fixedly connected to the side wall of the water storage tank 53.

[0043] In this embodiment, when the mine washing machine is working, the sewage generated by washing the ore will flow into the sedimentation tank 62 through the sewage pipe 61 at the bottom of the box body 1. Under the action of gravity, impurities will gradually settle to the bottom of the sedimentation tank 62, realizing the preliminary separation of solid and liquid in the sewage. When the precipitated water reaches a certain height and overflows the filter tube 63, the water will flow into the filter tube 63, and the filter screen 64 will intercept and filter some fine impurities remaining in the water. The water filtered by the filter screen 64 finally flows into the water storage tank 53. This design realizes the recycling and reuse of water resources through the cooperation of the water spraying mechanism 5 and the filtering mechanism 6, embodies good environmental protection and economy, and reduces production costs.

[0044] In a further embodiment, a stirring motor 71 is fixedly installed on the other side of the top of the box body 1, and a first pulley 72 is fixedly sleeved on the output shaft of the stirring motor 71. A belt 73 is meshedly installed on the outer surface of the first pulley 72, and a second pulley 74 is meshedly installed on the bottom end of the belt 73. The second pulley 74 is fixedly sleeved on the outer surface of one end of the diverter pipe 56, and a bearing 75 is fixedly sleeved in the middle of the diverter pipe 56. A plurality of connecting plates 76 are fixedly connected to the outer surface of the bearing 75, and one end of the plurality of connecting plates 76 is fixedly connected to the inner wall of the filter cartridge 43.

[0045] In this embodiment, when the mine washing machine is working, the stirring motor 71 is started, and its output shaft drives the first pulley 72 to rotate, and the first pulley 72 drives the second pulley 74 to rotate through the belt 73. When the second pulley 74 rotates, it drives the shunt pipe 56 to rotate synchronously. The bearing 75 in the middle of the shunt pipe 56 plays a supporting role. The shunt pipe 56 drives several stirring pipes 57 and their nozzles 58 to rotate accordingly. At the same time, the nozzle 58 washes the ore, and the rotation direction of the shunt pipe 56 is opposite to the rotation direction of the filter cylinder 43, so that the cleaning is more thorough. This design cooperates with the water spraying mechanism 5 and the stirring mechanism 7. On the one hand, the stirring action can make the ore in a constantly changing position and state, so that the water sprayed by the nozzle 58 can cover different parts of the ore, avoiding the occurrence of cleaning dead corners; on the other hand, while the water spraying mechanism 5 washes the ore, it also helps to make the friction between the ores smoother, further improving the effect of stirring to remove impurities, and improving the working efficiency of the entire device.

[0046] In a further embodiment, a feeding auger 44 is fixedly connected to the inner wall of the convex tube at the front end of the filter cartridge 43 , and a plurality of arc-shaped plates 45 are fixedly connected to the inner wall of the filter cartridge 43 .

[0047] In this embodiment, the feeding auger 44 will continuously push the incoming ore into the filter barrel 43 as the filter barrel 43 rotates, ensuring that the ore can be distributed relatively smoothly and evenly in the filter barrel 43, avoiding accumulation of ore at the entrance, thereby ensuring that subsequent tumbling, cleaning and other processes can be carried out in an orderly manner. When the ore is in the filter barrel 43, the arc plate 45 will push the ore, causing the ore to change its motion trajectory, achieving more sufficient and diversified tumbling, and enhancing the cleaning effect.

[0048] In a further embodiment, a plurality of limiting grooves 46 are opened on the outer surface of the filter cartridge 43, a rotating shaft 48 is symmetrically arranged at the bottom of the filter cartridge 43, a plurality of load-bearing wheels 47 are fixedly sleeved on the outer surface of the rotating shaft 48, and the outer surfaces of the plurality of load-bearing wheels 47 are in contact with the inner walls of the limiting grooves 46.

[0049] In this embodiment, when the filter cartridge 43 rotates, the load-bearing wheel 47 rolls along the inner wall of the limiting groove 46. The limiting groove 46 limits the load-bearing wheel 47 to prevent the load-bearing wheel 47 from being offset, thereby ensuring that the filter cartridge 43 will not be displaced and always rotates stably around the axis, ensuring that the tumbling, cleaning and other processes of the ore inside the filter cartridge 43 can be carried out normally and orderly.

[0050] In a further embodiment, a scraper 59 is fixedly connected to the top of a plurality of stirring tubes 57 , and the length of the scraper 59 is greater than the diameter of the filter holes on the inner wall of the filter cartridge 43 .

[0051] In this embodiment, during the operation of the ore washing machine, the stirring tube 57 will rotate together with the diversion tube 56, and the scraper 59 at the top of the stirring tube 57 will also make a circular motion, which can scrape and clean the impurities attached to the filter holes near the inner wall of the filter barrel 43 and the remaining small part of the ore particles, effectively preventing the filter holes on the inner wall of the filter barrel 43 from being blocked by impurities, and always ensuring that the filter barrel 43 has a good filtering function.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
