[0015] Advantageous Effects

[0016] The present invention provides a washing and separating device for mine exploitation, which has the following advantageous effects compared with the prior art:

[0017] 1. In the present invention, through the set linkage cleaning and discharging assembly, during the operation of the mine, the ore to be washed and selected is put into the washing box through the feeding box. After being put in, the ore accumulates on the surface of the washing tray. The conical gear disk is connected inside the connecting frame through the transmission of the micro motor. After the micro motor is started, the power is transmitted to the transmission shaft through the conical gear disk. The upper and lower ends of the transmission shaft are respectively rotatably connected to the upper and lower sides inside the positioning frame, and are meshed with the engaging teeth inside the conical gear disk through the transmission gear to achieve the transmission and conversion of power. The gear A at the upper end of the upper transmission shaft is meshed and connected with the gear B. The eccentric arm on the upper surface of the gear B is connected with the reciprocating pull head through the movable arm, forming a set of linkage mechanism. The front end of the reciprocating pull head is rotatably connected with the stretching frame, and the stretching frame is fixedly connected to the rear side of the washing tray. The washing tray can slide inside the washing box. When the micro motor is started, through a series of gear transmissions and the movement of the eccentric arm, the reciprocating pull head drives the stretching frame and the washing tray to move reciprocally inside the washing box, realizing the cleaning and screening functions of the washing tray. When the bottom of the washing tray touches the vibration contact head, due to the certain elasticity of the vibration contact head, they will generate an upward thrust on the washing tray, causing the washing tray to vibrate up and down while moving, which helps to break the adhesion force between mineral particles, making it easier to wash off the impurities and fine particles attached to the minerals, making the screening process more refined, and improving the quality of the final product. In addition, during the reciprocating movement of the washing tray, under the action of the washing tray on the linkage cylinder, the linkage cylinder rolls. While the linkage cylinder rolls, the vibration contact heads on its surface squeeze the air pressure bag. After the air pressure bag is deformed, it bulges downward airflow towards the surface of the washing box through the air duct and the air nozzle. Under the action of this airflow, the blockage of the screening holes can be reduced;

[0018] 2. In the present invention, through the set coal mine spraying assembly, the multiple screening holes opened on the surface of the washing tray cooperate with the multiple coal mine spraying assemblies on the upper surface of the water retaining cover, including the spraying frame, the water guide pipe, the spraying plate, the cleaning spray head and the water inlet pipe, to work together. The spraying frame is fixed on the left and right sides of the water retaining cover. The water guide pipe on its lower surface conveys the water provided by the liquid pump inside the water storage tank to the cleaning spray head at the upper end of the spraying plate, realizing the uniform spraying of the minerals on the washing tray. The minerals enter the guide hopper through the feeding box and fall onto the washing tray inside the washing box. While the washing tray is moving, the spraying water flow flushes the minerals. The fine particles and impurities are discharged through the screening holes, while the clean minerals remain on the washing tray. Through the uniformly sprayed water flow, the soil and impurities attached to the surface of the minerals can be effectively washed, improving the cleaning efficiency of the minerals.

A micro motor 712 is arranged inside the tapered gear disk 702. The output end of the micro motor 712 is in transmission connection with the tapered gear disk 702. A positioning frame 704 is fixedly connected to the outside of the micro motor 712. Transmission shafts 705 are arranged on both the upper and lower sides inside the positioning frame 704. The upper and lower ends of the upper and lower two transmission shafts 705 are respectively rotatably connected to the upper and lower sides inside the positioning frame 704. Transmission gears 703 are fixedly connected to the outer sides of the two transmission shafts 705. The two transmission gears 703 are respectively meshed and connected with the teeth at the upper and lower positions on the inner side of the tapered gear disk 702.

One end of the movable arm 709 away from the eccentric arm 708 is rotatably connected to a reciprocating pull head 710. The front end of the reciprocating pull head 710 is rotatably connected to a stretching frame 8. One end of the stretching frame 8 away from the reciprocating pull head 710 is fixedly connected to the rear side of the washing plate 5.

The upper ends of the fixed arms 713 are fixedly connected to the lower surface of the water baffle 6. A plurality of vibration contacts 715 are arranged around the outer surface of each linkage cylinder 714. The vibration contacts 715 are elastic. The arrangement of the linkage cylinders 714 and the vibration contacts 715 enables the washing plate 5 to generate up-and-down shaking during the movement, which can effectively improve the cleaning efficiency and remove stubborn impurities on the surface of the minerals. On the other hand, the shaking effect of the vibration contacts 715 helps to prevent the washing plate 5 from reducing the working efficiency due to the blockage of mineral particles and maintain the continuity and stability of the washing process. The design of the linkage cleaning plate assembly 7 and the vibration contacts 715 improves the cleaning efficiency and screening accuracy, reduces the energy consumption and maintenance cost. At the same time, the operation is simple, the maintenance is convenient, and the adaptability is strong, providing a more efficient and more environmentally friendly washing solution for the mining field.

The gear A 706 at the upper end of the upper transmission shaft 705 is meshed and connected with the gear B 707. The eccentric arm 708 on the upper surface of the gear B 707 is connected to the reciprocating pull head 710 through the movable arm 709 to form a set of linkage mechanisms. The front end of the reciprocating pull head 710 is rotatably connected with a stretching frame 8, and the stretching frame 8 is fixedly connected to the rear side of the washing tray 5. The washing tray 5 can slide inside the washing tank 2. When the micro motor 712 is started, through a series of gear transmissions and the movement of the eccentric arm 708, the reciprocating pull head 710 drives the stretching frame 8 and the washing tray 5 to move reciprocally inside the washing tank 2, realizing the cleaning and screening functions of the washing tray 5. When the bottom of the washing tray 5 touches the vibration contact 715, due to the certain elasticity of the vibration contact 715, they will generate an upward thrust on the washing tray 5, causing the washing tray 5 to vibrate up and down while moving, which helps to break the adhesion force between mineral particles, making the impurities and fine particles attached to the minerals easier to be washed off, making the screening process more delicate, and improving the quality of the final product.
