[0024] In this embodiment, the spiral blade assembly includes a spiral liner 3 and a spiral blade 2. The spiral blade 2 is fixedly arranged on the circumference of the shaft body 1, and the spiral liner 3 is connected to the spiral blade 2 by screws. Furthermore, the spiral liner 3 at the front section of the shaft body 1 has a 2-pitch screw, and the spiral liner 3 at the rear section of the shaft body 1 has a 1-pitch screw. The cleaned ore can be quickly transported to the discharge port through the spiral liner 3 at the front section of the shaft body 1. The residence time of the ore in the ore washing section is reduced to avoid congestion in the middle. The ore can be quickly transported through the spiral liner 3 at the rear section of the shaft body 1. The residence time of the ore at the tail of the trough is reduced.

[0025] The shaft body 1 is a seamless steel pipe with high strength, good wear resistance and reduced overall weight, ensuring that the screw shaft maintains excellent performance stability under long-term operation. Flanges 7 are provided at both ends of the shaft body 1 to facilitate connection with the coupling 9. A rib plate 6 is provided between the flange 7 and the outer side of the shaft body 1, which not only strengthens the connection strength between the shaft body 1 and the flange 7, but also enhances the rigidity of the entire shaft body, effectively resisting vibration and impact during operation.

[0026] The turning blade assembly includes a blade seat 4 and a blade 5. The blade seat 4 is fixedly arranged on the circumference of the shaft body 1. Preferably, the blade seat 4 is welded by a support plate and a rib plate and a circular hole is provided on the support plate for installing the blade. The blade 5 is connected to the blade seat 4 by a screw, and the water hole is located at the outer edge of the blade 5.

[0027] It is worth noting that in this embodiment, water holes are provided at the edges of the turning blade assembly, so that when the blade rotates, the slurry flows from the periphery of the blade and the water filter holes, forming turbulence behind the blade, which can improve the pulping capacity during the ore washing process and thus improve the cleaning effect.

[0028] On the basis of the above embodiment, the utility model also provides a double spiral trough type ore washing machine. Figure 2 As shown, the shaft body 1 is rotatably arranged in the groove body 12 , a driving mechanism is arranged on one side of the groove body 12 , the driving mechanism is dynamically connected to the shaft body 1 , and an overflow groove 14 is arranged on the other side of the groove body 12 .

[0029] Furthermore, the driving mechanism includes a reducer 8, a coupling 9, a gear 10 and a bearing seat 11. The reducer 8 is connected to the coupling 9. The end of the coupling 9 passes through the bearing seat 11 and is fixedly connected to the flange 7 of the shaft body 1. The gear 10 is fixedly set on the coupling 9, and the gear 10 is used to synchronously drive another shaft body 1. A tail bearing 13 is provided in the groove body 12, and the tail end of the shaft body 1 is passed through the tail bearing 13.

[0030] During operation, the reducer 8 rotates the gear 10 via the coupling 9, which in turn drives the two shaft bodies 1 to rotate within the trough 12. The rotation of the spiral blades forms a continuous spiral conveying channel, mixing the ore with water and conveying it upward into the trough. During this process, impurities such as dust and soil in the ore are separated and discharged with the water through the overflow trough 14, thereby achieving efficient ore cleaning and effective impurity separation. Finally, the cleaned ore is discharged from the discharge port of the ore washer, completing the entire ore washing process.
