Place gold ore is placed in the screen frame 20. The second motor 32 is activated to drive the screen frame 20 to rotate, which enables the place gold ore to be separated by centrifugation. The place gold passes through the screen frame 20 and falls into the screening box 13 for separation of place gold ore.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 9 As shown, the limiting mechanism includes a third connecting frame 9 and a first slider 10.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, a first collection box 11 is slidably mounted on the top of the top plate 1. Multiple first handles 26 are mounted on the first collection box 11, with two handles 26 symmetrically mounted on both sides of the first collection box 11. First anti-slip pads are mounted on the first handles 26. By setting up the first collection box 11, it is easy to collect impurities poured out by the mesh frame 20.

[0033] In this embodiment, as Figures 1-9 As shown, the working process of a gravity separation device for placer gold deposits is as follows:

[0034] Step 1: Place the placer gold ore in the mesh frame 20. Start the second motor 32 to drive the second rotating plate 29 to rotate, which in turn drives the mesh frame 20 to rotate and centrifuge the placer gold ore. The placer gold passes through the mesh frame 20 and falls into the second collection box 22 for collection. When the second collection box 22 is full, the second slider 23 slides in the second chute to disassemble the full second collection box 22.

[0035] Step 2: After screening, the second hydraulic telescopic rod 14 is activated to move the screen frame 20 out of the screening box 13. The electric slide rail 2 is activated to move the screen frame 20 away from the screening box 13. The second hydraulic telescopic rod 14 is activated to lower the screen frame 20. The limiting frame 17 is aligned with the first slider 10. The electric slide rail 2 is activated to move the screen frame 20. The first slider 10 slides into the limiting frame 17. The first hydraulic telescopic rod 4 is activated to move the first insert 8 and insert it into the first slot. The first motor 6 is activated to rotate the first insert 8, which in turn causes the screen frame 20 to tilt and pour the impurities into the first collection box 11 for collection.

[0036] In summary, in this embodiment, by setting a second hydraulic telescopic rod 14, the second hydraulic telescopic rod 14 is activated to move the screen frame 20 out of the screening box 13. The electric slide rail 2 is activated to move the screen frame 20 to above the first collection box 11. The first hydraulic telescopic rod 4 is activated to move the first insert block 8 to insert the first insert block 8 into the first slot. The first motor 6 is activated to rotate the first insert block 8, thereby tilting the screen frame 20 and pouring the waste in the screen frame 20 into the first collection box 11 for collection. Placed gold ore is placed in the screen frame 20. The second motor 32 is activated to rotate the screen frame 20, which allows the gold ore to pass through the centrifugal force. The gold particles pass through the screen frame 20 and fall into the screening box 13 for separation. The first slider 10, slidably connected to the first chute, limits the movement of the first rotating plate 16, facilitating the rotation of the screen frame 20 when the first insert block 8 rotates. The second rotating block 30, rotatably connected to the second chute, allows the second rotating plate 29 to rotate on the support plate 28. The second motor 32 starts, driving the second rotating plate 29 to rotate, which in turn drives the screen frame 20 to screen the gold. The second ball bearing 31 reduces the friction of the second rotating block 30. The first rotating block 36, rotatably connected to the first chute... The first connecting frame 20 can be rotated to pour out impurities. The first ball bearing 34 reduces the friction of the first rotating block 36. The fourth slider 35, slidably connected to the fourth groove, guides and limits the second connecting frame 5. The first collection box 11 facilitates the collection of impurities poured out of the screen frame 20. The first handle 26 facilitates the handling of the first collection box 11. The first anti-slip pad increases the friction of the first collection box 11. The third slider 25, slidably connected to the third groove, facilitates the disassembly of the full first collection box 11. The third slider 25 is a T-shaped slider that works in conjunction with a T-shaped chute to guide and limit the first collection box 11. The second collection box 22 facilitates the collection of screened gold dust. The second handle 24 facilitates the handling of the second collection box 22. The second anti-slip pad increases the friction of the second handle 24. The support leg 21 supports the top plate 1. The second slider 23 is slidably connected to the second chute, facilitating the sliding disassembly of the full second collection box 22. The second slider 23 is a T-shaped slider that guides and limits the second collection box 22.
