[0015] A method for pretreating copper-sulfur ore comprises the following steps: S1. The ore to be processed is fed into the crusher housing through the feed pipe.

The shape of the crushed stones is relatively regular, which can reduce the stone powder rate during ore crushing, thereby improving the effective utilization rate of the stones, and then the stones are screened by the screening frame to achieve separation between stones of different volumes, thereby improving the processing effect of the stones.

[0017] In the present invention, one end of the conveying roller is rotatably connected to the frame. When the conveying roller is driven to rotate by the driving structure, the stone moves forward with the rotation of the conveying roller, thereby realizing the transportation of the stone. There is no need to manually move the screened stones, which reduces the amount of manual labor and shortens the time for ore processing, thereby improving the efficiency of the entire device during use. The recycling box can be used to collect crushed stone, which is convenient for subsequent centralized processing of the crushed stone, thereby reducing the waste of ore resources.

[0018] 3. In the present invention, the top of the reinforcement plate is fixedly connected to the guide plate and the guide plate. When the rack 1 is driven to move by the hydraulic push rod, the gear rotates on one side of the guide plate, thereby driving the rack 2 and the connecting piece to move, so as to realize the movement of the inner cylinder inside the outer cylinder. The reciprocating movement of the inner cylinder inside the outer cylinder can improve the cleaning effect of the stone, reduce the residual dust and impurities on the surface of the stone, and thus improve the purity of the stone during subsequent processing.

The bottom of the extension plate 311 is slidably connected to the outer cylinder 32, and one side of the outer cylinder 32 is fixedly connected to a drain pipe.

[0026] In this embodiment, the reinforcing plate 44 can be used to support and reinforce the bottom of the hydraulic push rod 34 and the guide plate 35, which can improve the stability of the hydraulic push rod 34 and the guide plate 35 when in use. The guide plate 35 can be used to guide one end of the rack 1 33 and the rack 2 36, thereby improving the stability of the rack 1 33 and the rack 2 36 when moving.

[0027] Embodiment 3: A method for pre-treating copper-sulfur ore, comprising the following steps: Step 1: Feed the ore to be processed into the crusher housing 55 through the feed pipe 1, and the two crushing teeth 54 crush the ore. The crushed stones enter the screening frame 56, and the screening frame 56 is driven to vibrate by the vibration motor 57, and the built-in screening plate 561 screens the stones; Step 2: The sieved stones are discharged from one side of the sieve frame 56 and fall onto the conveyor roller 42. The larger stones can be transported along with the conveyor roller 42, and the smaller stones fall into the recovery box 43 for collection; Step 3: When the stone moves to the end of the rack 41, it may fall into the inner cylinder 31. At this time, the stone is first soaked in the inner cylinder 31, and then the hydraulic push rod 34 drives the rack 1 33 to move to the side away from the outer cylinder 32. Under the action of the gear 37, the rack 2 36 and the connecting piece 38 move to the side close to the outer cylinder 32, driving the inner cylinder 31 to move inside the outer cylinder 32, so as to flush and clean the stone; Step 4: After the stones are cleaned, the drain pipe on one side of the outer cylinder 32 is opened to drain the waste water, and the stones are drained inside the inner cylinder 31.

The screened stones fall on the conveying roller 42 and gradually move forward with the rotation of the conveying roller 42 until they fall from the conveying roller 42 and enter the built-in cylinder 31. At this time, the built-in cylinder Water is stored in the inner cylinder 31, and stones enter the inner cylinder 31 for soaking. When all the stones enter the inner cylinder 31, the servo motor 52 and the conveying roller 42 stop working, and the hydraulic push rod 34 is used to drive the rack 1 33 to move back and forth along the guide plate 35. Since the upper and lower sides of the gear 37 are respectively engaged with the rack 1 33 and the rack 2 36, the movements of the rack 1 33 and the rack 2 36 are opposite, and the rack 2 36 and the connecting piece 38 reciprocate in the opposite direction to the rack 1 33, thereby realizing the reciprocating movement of the inner cylinder 31 inside the outer cylinder 32, and the stones are flushed with water to achieve the cleaning of the stones, until the waste water is discharged after the stone cleaning is completed.
