Aiming at the defects in the prior art, the invention provides the ore washer which has the advantage of directly grading and guiding out the mineral aggregate after cleaning.

In order to achieve the purpose, the invention provides the following technical scheme:

a log washer comprises a rack and an installation cavity arranged in the rack, wherein a screen drum is rotatably connected in the installation cavity, two ends of the screen drum along the axial direction penetrate through the installation cavity, and a driving motor for driving the screen drum to rotate is further arranged on the rack; the rotating axis of the screen cylinder is obliquely and downwards arranged, the screen cylinder comprises an inner cylinder body and an outer cylinder body coaxially fixed on the outer side of the inner cylinder body, a containing cavity is arranged between the inner cylinder body and the outer cylinder body, screen holes are formed in the inner cylinder body and the outer cylinder body along the circumferential direction, and the diameter of each screen hole in the inner cylinder body is larger than that of each screen hole in the outer cylinder body; a feed inlet and a coarse material outlet are respectively arranged at two ends of the inner cylinder body along the axial direction, the feed inlet is positioned at the higher end, one end of the inner cylinder body, which is provided with the coarse material outlet, protrudes out of the outer cylinder body, and a fine material outlet is also arranged at one end of the outer cylinder body, which is far away from the feed inlet; the machine frame is also provided with a first cleaning assembly, the first cleaning assembly comprises a water guide pipe which is axially arranged in the inner cylinder in a penetrating way along the inner cylinder, and a spray header which is used for spraying and cleaning mineral aggregate is arranged along the length direction of the water guide pipe, and the water guide pipe is used for communicating with a water source; the lower end of the installation cavity is also communicated with a waste liquid outlet.

Through above-mentioned technical scheme, after the mineral aggregate was added to the inner tube body through the feed inlet, the rotation through a sieve section of thick bamboo and the spraying of first cleaning assembly were washd the mineral aggregate. Simultaneously, at a sieve section of thick bamboo pivoted in-process, because the sieve mesh of interior barrel is greater than the sieve mesh of outer barrel, when the granularity of mineral aggregate was less than the sieve mesh of interior barrel, the mineral aggregate just can enter into the chamber that holds between outer barrel and the interior barrel through the sieve mesh of interior barrel, and the sieve mesh on the outer barrel supplies waste water and silt to pass through usually to carry out further separation to the mineral aggregate that holds the intracavity. After the mineral aggregate is cleaned, the mineral aggregate with the granularity larger than the diameter of the sieve pore of the inner cylinder body can be discharged from the coarse aggregate outlet, and the mineral aggregate in the containing cavity is discharged from the fine aggregate outlet, so that the mineral aggregate is classified. Barrel, outer barrel and first washing subassembly in setting up combine spraying of first washing subassembly through the rotation of a sieve section of thick bamboo, have realized accomplishing the hierarchical operation of mineral aggregate when the mineral aggregate washs for direct hierarchical derivation after the mineral aggregate washs, thereby make holistic use more convenient.

Furthermore, one end of the fine material outlet of the outer cylinder is fixedly connected to the inner cylinder through a connecting rod.

Through above-mentioned technical scheme, the one end that outer barrel is close to the fine aggregate export is passed through connecting rod fixed connection on interior barrel, has reduced the mineral aggregate and has held the accumulational condition of intracavity to it is more convenient to make the ejection of compact of fine aggregate export.

Further, still be provided with the second in the frame and wash the subassembly, the second washs the subassembly and is located the thin material export one end of outer barrel, just the second washs the subassembly and is located the one side that the feed inlet was kept away from in the thin material export, the second washs the subassembly including set up in barrel below be used for communicateing to the arc pipe at water source, communicate in the nozzle of arc pipe, the nozzle is towards the thin material export, just the nozzle sets up towards the lower extreme inside wall of outer barrel.

Through above-mentioned technical scheme, set up the second and wash the subassembly, the second washs the subassembly and can aim at the thin material export and spray to wash once more from thin material export exhaust mineral aggregate, make the cleaning performance of thin material export exhaust mineral aggregate better.

Furthermore, the lower end of the fine material outlet is also provided with a material guide plate, and the material guide plate is obliquely and downwards arranged towards the direction vertical to the axis of the screen cylinder.

Through above-mentioned technical scheme, be provided with the stock guide, lead to the discharge to appointed place to the mineral aggregate of thin material export discharge through the stock guide to make the discharge of mineral aggregate collect more convenient.

Furthermore, the arc-shaped pipe is connected to a water source through a hose, a hinge rod is arranged on the arc-shaped pipe, the arc-shaped pipe is hinged to the rack through the hinge rod, and the hinge rod is arranged downwards in an inclined manner towards the direction of the rack; the lateral wall of interior barrel is fixed with the bulge loop, the bulge loop corresponds the arc tube sets up, the axial lead of bulge loop with the axial lead of interior barrel is the dislocation set, the up end of arc tube correspond be provided with bulge loop lateral wall complex touch panel, still be provided with in the frame to support tightly touch panel in the piece that supports of bulge loop lateral wall.

Through above-mentioned technical scheme, when a sieve section of thick bamboo rotates, a sieve section of thick bamboo rotates and can drive the bulge loop and rotate, through the tight effect of supporting of piece for the bulge loop can support the conflict board of tight arc and move the arc and overturn from top to bottom along articulated axis, thereby can adjust the angle of spraying of the nozzle of second cleaning assembly, make the second cleaning assembly better to the cleaning performance of thin material export.

Further, it is tensioning spring to support the piece, tensioning spring one end fixed connection just other end fixed connection in the frame on the hinge bar, tensioning spring fixed connection is higher than in the one end of frame the hinge bar sets up with the articulated position of frame, tensioning spring's elasticity makes the conflict board contradict in the bulge loop lateral wall.

Through the technical scheme, the arc-shaped pipe can be abutted to the convex ring through the abutting plate through the tension spring, so that the arc-shaped pipe can swing up and down along the eccentric rotation of the convex ring, the spraying angle of the nozzle is changed, and the cleaning effect of the second cleaning assembly is better.

Further, the inside wall of interior barrel has a plurality of fender material groups along the axial fixity, and every keeps off the material group and all includes a plurality of baffles that set up along interior barrel circumference interval, all leaves the blanking mouth between the adjacent baffle.
