[0082] The vibration motor 16 is fixedly arranged on the assembly disc 132;

[0083] The cam 142 is provided with four, the number of the cam 142, the rotating piece 141 and the driving piece 143 is equal, and they are arranged in one-to-one correspondence.

[0084] In the embodiment, the cam 142 comprises two use states:

[0085] The expanded state, as shown in Figure 6 The convex part of the cam 142 is away from the butt joint range of the annular groove 1321, which provides a clearance for the assembly of the device;

[0086] The limiting state, as shown in Figure 5 The convex part of the cam 142 is inserted into the butt joint range of the annular groove 1321, and there is enough play to facilitate locking of the assembled device, which means that the overall suspension adjustment of the butt joint disc 123, the assembly disc 132 and the sorting disc 131 is allowed without causing the device to loosen and the connection to fall off.

[0087] In this embodiment, the motor 151 is used to drive the second gear 152 to rotate, which in turn drives the second gear ring 153 to rotate, and the second gear ring 153 in turn drives the butt joint base 121 and the drive roller 124 to rotate and adjust on the mounting base 111, thereby providing power for stable rotation adjustment of the assembled sorting disc 131.

[0088] In this embodiment, the vibration motor 16 is composed of a mounting frame, a motor and a swing wheel, which is a prior art and will not be described in detail here. It is integrated on the butt joint disc 123 and driven by the assembly disc 132 to vibrate and adjust the sorting disc 131, thereby providing support for the suspension screening above the surface of the sorting disc 131.

[0089] Device assembly principle:

[0090] Before assembly, the mounting base 111 is fixedly installed on the ground;

[0091] During assembly, the middle part of the butt joint base 121 is sleeved on the butt joint shaft 112 to realize quick butt joint between the butt joint base 121 and the mounting base 111, and the bottom of the drive roller 124 is supported on the rotation range of the mounting base 111;

[0092] Then start the drive member 143, which drives the cam 142 to rotate through the rotating member 141, and the cam 142 switches from the limiting state to the expanded state, so that the top of the butt joint disc 123 leaves a clearance;

[0093] Then align and insert the insertion shaft 133 at the bottom of the assembly disc 132 with the butt joint slot 1231, and after insertion, the annular groove 1321 is aligned in the rotation range of the cam 142;

[0094] Finally, the driving member 143 is started, the driving member 143 drives the cam 142 to rotate through the rotating member 141, and the cam 142 is switched from the unfolded state to the limiting state;

[0095] Finally, the whole equipment is quickly assembled and locked, and a plurality of bolts are not needed to be used for multiple installation and adjustment, so that the whole equipment assembly difficulty is reduced, and the equipment assembly efficiency is improved.

[0096] By adopting the quick assembly structure, on the one hand, the technical requirements of the installation personnel can be reduced, and on the other hand, the equipment assembly efficiency can be improved, and the installation period required when multiple sets of equipment are installed can be reduced.

[0097] Preferably, the rotating member 141 is a spring contraction pipe member, which provides elastic support for the up-down vibration between the cam 142 and the assembly disc 132. Therefore, the assembly disc 132 and the sorting disc 131 can not only horizontally vibrate but also up-down vibrate in the vibration process.

[0098] In an optional embodiment of the embodiment, the driving member 143 can be a motor structure. The rotating member 141 is directly driven to rotate and adjust by the driving member 143, the rotating member 141 is rotated and adjusted at the same time, and the cam 142 is synchronously driven to rotate. Therefore, each cam 142 is controlled individually.

[0099] In another optional embodiment of the embodiment, please refer to Figure 3 and Figure 4 , the adjustment cavity 1211 and the movable hole 1212 are arranged on the docking base 121 and are in communication with each other;

[0100] The driving member 143 comprises a first gear ring 1431, a connecting sliding block 1432, a first telescopic member 1433 and a first gear 1434. The first gear ring 1431 is rotatably installed on the docking base 121 and is located in the range of the adjustment cavity 1211. One end of the connecting sliding block 1432 penetrates through the movable hole 1212 and is fixedly connected with the first gear ring 1431. The two ends of the first telescopic member 1433 are respectively hinged to the docking base 121 and the connecting sliding block 1432. The bottom of the rotating member 141 penetrates through the docking base 121 and is fixedly connected with the first gear 1434. The first gear 1434 is meshingly connected with the first gear ring 1431.

[0101] In the embodiment, the first telescopic member 1433 can be an electric telescopic rod, which is used to drive the connecting sliding block 1432 to slide and adjust in the range of the movable hole 1212, so as to provide power for the rotation and adjustment of the first gear ring 1431.

[0102] The synchronous adjustment principle of the cam 142 is as follows:

[0103] When the first telescopic part 1433 drives the connecting sliding block 1432 to slide at the active hole 1212, the connecting sliding block 1432 drives the first gear ring 1431 to rotate counterclockwise, and the first gear ring 1431 drives the first gear 1434 to rotate clockwise at the same time, so that the cam 142 is switched from the limiting state to the unfolded state, facilitating the rapid assembly of the equipment.

[0104] When the first telescopic part 1433 drives the connecting sliding block 1432 to slide at the active hole 1212, the connecting sliding block 1432 drives the first gear ring 1431 to rotate counterclockwise, and the first gear ring 1431 drives the first gear 1434 to rotate clockwise at the same time, so that the cam 142 is switched from the limiting state to the unfolded state, facilitating the rapid assembly of the equipment.

[0105] Conveniently, under the driving action of the first telescopic part 1433, the rotation adjustment of the four first gears 1434 is simultaneously realized, so that the synchronous rotation adjustment of the four cams 142 is realized.

[0106] The working principle of the suspension beneficiation equipment provided in the embodiment is as follows:

[0107] Step A1, first, the mounting base 111 is fixedly installed on the ground, then the middle part of the butt joint base 121 is sleeved on the butt joint shaft 112, the bottom of the driving roller 124 is supported in the rotation range of the mounting base 111, and the butt joint disc 123, the cam 142 and the vibration motor 16 are integrally installed, facilitating the rapid assembly of the equipment.

[0108] Step A2, the first telescopic part 1433 is started, and the first telescopic part 1433 controls the cam 142 to be switched from the limiting state to the unfolded state, providing a clearance for the installation of the assembly disc 132.

[0109] Step A3, after the insertion shaft 133 at the bottom of the assembly disc 132 is aligned with the butt joint slot 1231, the insertion shaft 133 is controlled to be directly inserted into the range of the butt joint slot 1231, and the bottom of the assembly disc 132 is supported on the butt joint disc 123, and the annular groove 1321 is aligned in the rotation range of the cam 142.

[0110] Step A4, the first telescopic part 1433 is started, and the first telescopic part 1433 controls the cam 142 to be switched from the unfolded state to the limiting state, providing locking after the installation of the assembly disc 132.

[0111] Step A5, during the operation of the device, the docking base 121 as a whole is rotated and adjusted on the mounting base 111 by the motor 151, and the suspension vibration of the docking disc 123, the assembly disc 132 and the sorting disc 131 is powered by the vibration motor 16.

[0112] Second embodiment:

[0113] Please refer to Figure 7 Based on the first embodiment of the application, the second embodiment of the application provides another kind of suspension mineral separation device. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the separate implementation of the first embodiment.

[0114] Specifically, the difference between the suspension mineral separation device provided by the second embodiment of the application is that the suspension mineral separation device further comprises a brake mechanism 6, the brake mechanism 6 comprises a second telescopic piece 61 and a brake disc 62, the fixed part of the second telescopic piece 61 is fixed on the docking base 121, and the telescopic part of the second telescopic piece 61 is fixedly connected with the brake disc 62 after penetrating through the docking base 121.

[0115] When the bottom of the brake disc 62 abuts against the running wheel of the driving roller 124, the driving roller 124 is locked.

[0116] In this embodiment, the second telescopic piece 61 can be an electric telescopic rod, which can be directly embedded and installed on the docking base 121, and is used to drive the lifting adjustment of the brake disc 62, so as to facilitate the separate driving control of the brake disc 62.

[0117] By integrally installing the second telescopic piece 61 on the docking base 121, the lifting adjustment of the brake disc 62 is facilitated, and when the brake disc 62 abuts against the running wheel of the driving roller 124, the driving roller 124 is locked, which provides stable support for the assembly of the device and avoids that the driving roller 124 drives the docking base 121 to freely rotate on the mounting base 111 during the assembly of the device, thereby facilitating the stable assembly of the device.

[0118] When the brake disc 62 is separated from the running wheel of the driving roller 124, the driving roller 124 is unlocked, which ensures the stability of the rotational adjustment of the driving roller 124 on the mounting base 111 during the operation of the device.

[0119] Specifically, the brake disc 62 is of rubber structure, the bottom is of arc structure and is aligned with the top of the driving roller 124.

[0120] The working principle of the suspension beneficiation equipment provided by the embodiment is as follows:
