Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically a cleaning device for mining machinery. Background Technology

[0002] Mining vibrating screens are industrial machines that use the rotating weights of vibrators to cause planar gyratory vibrations on the screen surface to screen industrial raw materials such as ores. During long-term use, the dust generated by the vibrating screen can clog the screen mesh. To address this issue, a mining vibrating screen with a cleaning structure is often used.

[0003] Patent application CN220804402U discloses a mineral screen for easy cleaning, comprising a first collection box, a second collection box, and a screen box. The second collection box is fixedly connected to the bottom left side of the first collection box, and the screen box is movably connected inside the second collection box. The screen box has mounting grooves on both the front and back sides of its inner wall. A transmission mechanism is fixedly connected to the front and rear sides of the right side of the screen box, and a storage box is fixedly connected to the left side of the screen box. This invention solves the problem of impurities remaining on the screen during ore screening, which can then re-adhere to the ore, affecting screening. This invention provides the advantage of a screen cleaning mechanism.

[0004] However, the cleaning efficiency of the above-disclosed easy-to-clean mining screens is generally low, and they cannot clean the upper and lower sides of the screen simultaneously. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning device for mining machinery in order to solve the problems of the general cleaning efficiency of existing easy-to-clean mining screens and the inability to clean the upper and lower sides of the screen simultaneously.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a cleaning device for mining machinery, comprising an inclined feeding bin, a screening frame movably mounted on the top of the feeding bin, a rack fixedly mounted on the outer wall of the screening frame, a drive motor mounted on the inner wall of the feeding bin, and a special-shaped gear intermittently meshing with the rack mounted on the output end of the drive motor; symmetrical motion motors mounted on the two outer walls of the feeding bin, screws mounted on the output ends of the motion motors, a motion frame movably mounted between the screws, a cleaning motor mounted on the outer wall of the motion frame, and a brush for cleaning the top of the screening frame mounted on the output end of the cleaning motor; multiple sets of cylinders mounted on the two outer walls of the feeding bin, and flexible scrapers for cleaning the bottom of the screening frame mounted on the output ends of the cylinders; a discharge port is provided on the side wall of the screening frame, and a plate is movably mounted on the discharge port.

[0007] As a further improvement of this utility model: the top of the feeding hopper is provided with symmetrical sliding grooves, the bottom of the screening frame is provided with a sliding rail that cooperates with it, and both sides of the sliding rail are connected with return springs.

[0008] As a further improvement of this utility model: the bottom of the feeding hopper is provided with multiple sets of support legs, and the outer wall of the feeding hopper is provided with a control panel.

[0009] As a further improvement of this utility model, threaded sleeves that cooperate with the screw are provided on both sides of the motion frame.

[0010] As a further improvement of this utility model: symmetrical limiting grooves are provided on the inner walls of both sides of the discharge port, limiting sliders that cooperate with the insert plate are provided on both sides of the insert plate, and handles are provided on the outer wall of the insert plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes a specially shaped gear and a return spring to drive the screening frame to reciprocate relative to the top of the feeding hopper, thereby efficiently screening the ore. After screening, larger stones remaining on the screening frame can be discharged through the drain port. Once the operation is complete, the motion motor and cylinders are activated. The motion motor drives the motion frame to reciprocate along the screening frame, thus efficiently cleaning its top. The cylinders on both sides can drive scrapers to reciprocate and clean the bottom of the screening frame. This design improves the stability and flexibility of this cleaning device for mining machinery. Attached Figure Description
