[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figures 1 to 4 As shown, a suspended three-layer mineral processing shaking table includes a bracket 1, on which a driving mechanism 2 is arranged, and the driving mechanism 2 is a conventional pulley transmission mechanism (including a motor, a driving wheel, a belt and a driven wheel), and the output end of the driving mechanism 2 is connected to a rocker 3, and the rocker 3 is connected to a connecting seat 41 through a bolt, and the connecting seat 41 is arranged on the horizontal end surface of the first screen 4, and two groups of bearing rollers 5 are symmetrically arranged at the bottom edge of the first screen 4, and the bearing rollers 5 are installed on the bracket 1. The driving mechanism 2 drives the rocker 3 to shake back and forth, thereby driving the first screen 4 to reciprocate, and in this process, the bearing rollers 5 play the role of bearing support and ensuring reciprocating motion for the first screen 4.

[0022] The first screen 4 is symmetrically provided with connecting components 6 on both longitudinal end surfaces. The first screen 4 is connected with the second screen 7 and the third screen 8 through the connecting components 6. The second screen 7 and the third screen 8 will reciprocate with the first screen 4 to achieve mineral separation.

[0023] Among them, the connecting component 6 includes a connecting block 61, which is symmetrically arranged on the two longitudinal end surfaces of the first screen 4. Two sets of slide grooves 62 are opened on the side of the connecting block 61 facing the second screen 7 and the third screen 8. Slide blocks 63 are slidably connected in the slide grooves 62, and the slide blocks 63 are respectively connected to the two longitudinal end surfaces of the second screen 7 and the third screen 8; a fixed frame 64 is arranged on the other side of the connecting block 61, and two positioning rods 65 are slidably connected in the fixed frame 64. The same extrusion plate 66 is arranged in the middle of the two positioning rods 65, and a spring 67 is arranged on the positioning rod 65 between the extrusion plate 66 and the outer frame of the fixed frame 64. The inner end surfaces of the two positioning rods 65 pass through the fixed frame 64 and the connecting block 61 in turn and are inserted into the positioning grooves 68 opened on the slider 63, and the outer end surfaces of the two positioning rods 65 are connected to the same pull plate 69.

[0024] During installation, the first screen 4 is placed on the load-bearing roller 5, and the connecting seat 41 is connected to the rocker 3 with bolts to realize the installation of the first screen 4; then the second screen 7 and the third screen 8 are installed, and the pull plates 69 of the two connecting components 6 are pulled, so that the pull plates 69 drive the positioning rod 65 to slide into the fixed frame 64, and the positioning rod 65 will drive the extrusion plate 66 to compress the spring 67 when sliding, causing the spring 67 to deform, and then the second screen 7 and the third screen 8 drive the respective corresponding sliders 63 to slide into the corresponding slide grooves 62, and align the positioning grooves 68 in the sliders 63 with the positioning rods 65, and then release the pull plate 69, and the restoring force of the spring 67 pushes the extrusion plate 66, so that the extrusion plate 67 drives the positioning rod 65 to reset and slide in the fixed frame 64 and insert it into the positioning groove 68, so that the second screen 7 and the third screen 8 are installed between the two connecting components 6, so that the second screen 7, the third screen 8 and the first screen 4 are installed together.

[0025] When disassembly is required, pull the pull plates 69 of the two connecting components 6 to make the positioning rod 65 slide out of the positioning groove 68, and then pull the second screen 7 and the third screen 8 to make the sliders 63 on the two longitudinal end faces of the two screens slide out of the slide groove 62, so that the second screen 7 and the third screen 8 can be disassembled; then remove the bolts connecting the connecting seat 41 and the rocker 3 to achieve the disassembly of the first screen 4.

[0026] The connecting assembly 6 can simply install and disassemble the second screen 7 and the third screen 8. The disassembly process does not require the aid of tools, which is convenient for replacing and cleaning the screens, thereby improving the practicality of the mineral processing shaking table. At least two connecting assemblies 6 are symmetrically arranged. Of course, if the stability is not enough, multiple groups can be symmetrically arranged, such as 4, 6, etc. In addition, the connecting block of the connecting assembly can also be provided with multiple chutes and other corresponding components in the vertical direction to realize the installation of multiple layers of screens as one. Of course, considering the stability, multiple groups of symmetrically arranged connecting assemblies are also required.

[0027] In this embodiment, a material chute 9 is arranged directly below the first screen 1, the top of the material chute 9 is connected to the bracket 1, and the bottom of the material chute 9 is connected to the storage box 10, which is arranged on the side of the bracket 1. The material chute 9 and the storage box 10 facilitate the collection and storage of the sorted minerals.

[0028] like Figure 5 Figure 6 As shown, in order to further improve the practicality of the equipment and facilitate the transfer of materials in the storage box 10, the storage box 10 is not fixed. However, considering the stable position of the storage box 10 relative to the discharge port, a limit frame 11 is provided under the storage box 10 in this embodiment to limit the storage box 10.

[0029] The specific structure of the limit frame 11 is as follows: a rotation groove 111 is provided in one side wall of the limit frame 11, a rotation rod 112 is rotationally installed in the rotation groove 111, the rotation rod 112 is rotationally connected to the limit plate 113, and a limit slot 114 is provided on the side wall of the limit frame 11 corresponding to the other end of the limit plate 113. At the same time, a torsion spring 115 is wound around the surface of the rotation rod 112, and the limit plate 113 is automatically closed by the reset elastic force of the torsion spring 115, which is convenient for operation; a buffer pad is provided on the bottom end surface of the limit plate 113, and the area of ​​the buffer pad is equal to the area of ​​the bottom end of the limit plate 113, so that when the limit plate 113 is closed, it is in soft contact with the bottom plate of the limit frame 11 to prevent impact damage.

[0030] When in use, the limit plate 113 is rotated so that the limit plate 113 drives the rotating rod 112 to rotate in the rotating groove 111, and the torsion spring 115 is twisted under the drive of the rotating rod 112. Then the storage box 10 is placed on the limit frame 11, so that the inner wall of the limit frame 11 fits with the outer wall of the storage box 10, and then the limit plate 113 is released. The restoring elastic force of the torsion spring 75 drives the rotating rod 112 to rotate in the rotating groove 111, and simultaneously drives the limit plate 113 to rotate and snap into the limit slot 114, thereby achieving the purpose of limiting the storage box 10.

[0031] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above, and any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
