[0042] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0043] See also Figure 1-4 The present application provides a tailings re-selection equipment device, including a screening box 1, a screening device, and a collecting assembly.

In this embodiment, a feed port 2 is provided at the top of the screening box 1, a discharge port 8 is provided at the bottom of the screening box 1, a plurality of L-shaped connecting holes 9 are provided inside the screening box 1, and the plurality of L-shaped connecting holes 9 are connected in sequence in a stepped manner. The feed port 2 and the discharge port 8 are connected to the plurality of L-shaped connecting holes 9, and a plurality of placement cavities 7 are provided on one side of the feed port 2, and the placement cavities 7 are connected to the L-shaped connecting holes 9.

[0044] The screening device is installed at the connection point of the adjacent placement chambers 7, and is used to drive the heavy materials to fall to a specified position after receiving the heavy materials, and drive the light materials to the next level of placement chamber 7 after receiving the light materials; specifically, the screening device includes a rotating plate 10, a second spring 19, and a limit block 20. The rotating plate 10 is installed on the L-shaped connecting hole 9 through the rotating shaft 18; the second spring 19 is installed on the bottom of the rotating plate 10 away from the L-shaped connecting hole 9; the limit block 20 is installed on the side of the rotating plate 10 close to the L-shaped connecting hole 9, and is used to clamp the rotating plate 10 to the stepped surface of the L-shaped connecting hole 9 after the rotating plate 10 is rotated to form a limit. In this embodiment, the rotating shaft 18 on the inner wall of the L-shaped connecting hole 9 and the outer wall of the rotating shaft 18 are fixedly sleeved with a rotating plate 10, and the inner wall of one side of the placement chamber 7 is fixedly connected with a fixed horizontal plate 17, and the top of the fixed horizontal plate 17 and the bottom end of the rotating plate 10 are fixedly connected with two symmetrically arranged second springs 19, and the bottom inner wall of the placement chamber 7 is fixedly connected with a first triangular block 3, and the mineral can be put into the device through the feed port 2, and the minerals slide along the surface of the first triangular block 3 at intervals in turn, and move along the surface of the limit block 20 to the inside of the L-shaped connecting hole 9, and the elastic force of multiple second springs 19 decreases in turn. If the heavy mineral can push the limit block 20 to rotate, the mineral can fall into the collection box 5 for collection. If the weight is not enough, it will continue to move downward to the next rotating plate 10 for screening.

[0045] The collecting assembly is installed on one side of the screening device, and is used to receive the heavy objects screened by the screening assembly, and is driven along the outside of the placement cavity 7 after the heavy objects are full. Specifically, the collecting assembly includes a collecting box 5, a compression spring 15, a first spring 13, and a support plate 11. The collecting box 5 is slidably connected to the inside of the placement cavity 7. The collecting box 5 is connected to the fixed vertical plate 16 through the compression spring 15. The inside of the collecting box 5 is slidably connected with the support plate 11. The support plate 11; one side of the compression spring 15 is connected to the collecting box 5, and the other side is connected to the fixed vertical plate 16; the first spring 13 is installed at the bottom of the collecting box 5; the support plate 11 is connected to the first spring 13, and is slidably connected to the inside of the collecting box 5. The collecting box 5 also includes a second triangular block 12 and a fixing rod 4. The second triangular block 12 is vertically installed on one side of the support plate 11; the fixing rod 4 is vertically installed on the top of the placement cavity 7, and is used to limit the second triangular block 12. In this embodiment, the second triangular block 12 and the fixed rod 4 can serve as an "action switch" after the heavy material is full. When it is not full, the first spring 13 always generates a restoring force to support the support plate 11. As the material increases, when the weight gradually increases, the support plate 11 drives the second triangular block 12 to move downward until it is full. The second triangular block 12 breaks away from the limit of the fixed rod 4, and under the action of the compression spring 15, the collection box 5 pops out.

[0046] On the basis of the above embodiment, the top of the support plate 11 is fixedly connected to the second triangular block 12, the top inner wall of the placement cavity 7 is fixedly connected to the fixing rod 4, the fixing rod 4 is used in conjunction with the second triangular block 12, the bottom of the fixed horizontal plate 17 is fixedly connected to the fixing vertical plate 16, the same push plate 14 is slidably connected between the inner walls on both sides of the placement cavity 7, two symmetrically arranged compression springs 15 are fixedly connected between the push plate 14 and the fixed vertical plate 16, the push plate 14 is used in conjunction with the collection box 5, the inner wall of the L-shaped connecting hole 9 is fixedly connected to the limiting block 20, the limiting block 20 is used in conjunction with one end of the rotating plate 10, which can help brake the collection box 5 and quickly pop out the collection box 5 after it is full.

[0047] During screening, the minerals can be put into the device through the feed port 2. The minerals slide along the surface of the first triangular block 3 at intervals in sequence, and move toward the inside of the L-shaped connecting hole 9 along the surface of the limit block 20. The elastic force of the multiple second springs 19 decreases in sequence. If the heavy minerals can push the limit block 20 to rotate, the minerals can fall into the collection box 5 for collection. If the weight is not enough, they continue to move downward to the next rotating plate 10 for screening. After the heavy objects are piled up, they gradually push the support plate 11 to move vertically downward. The support plate 11 squeezes the first spring 13 and drives the second triangular block 12 to move vertically downward. After the second triangular block 12 no longer contacts the fixed rod 4, the push plate 14 moves horizontally under the elastic force of the compression spring 15. The push plate 14 pushes the collection box 5 to move horizontally. The collection box 5 is moved out of the placement cavity 7 to facilitate the staff to handle the minerals. The inclined setting of the second triangular block 12 can facilitate the collection box 5 to be put in again.

[0048] In the embodiment of the present application, the screening component can be used to automatically screen minerals of different weights, thereby improving the screening effect; the collecting component can be used to automatically discharge the collecting box 5 after collecting a top of the material; during screening, the minerals slide along the surface of the first triangular block 3 in sequence and at intervals, and the minerals can fall into the interior of the collecting box 5 for collection. If the weight is not enough, it continues to move downward to the next rotating plate 10 for screening. After the heavy objects are accumulated, the second triangular block 12 no longer conflicts with the fixing rod 4, and the collecting box 5 is moved out from the inside of the placement cavity 7, making it convenient for the staff to handle the minerals.

[0049] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
