Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The purification of non-metallic mineral raw materials and the magnetic separation of coarse-grained weakly magnetic metal ores are mainly carried out by a closed magnetic circuit magnetic separator. The magnetic separator unloading device provided by the utility model unloads the material so that the material falls on the conveyor belt 12 for transportation, which is convenient for subsequent magnetic separation of these materials.

[0021] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a unloading device for a magnetic separator, comprising a mounting frame 1, a discharge box 3 is slidably connected to the top of the mounting frame 1, a connecting groove is opened inside the mounting frame 1, the bottom end of the discharge box 3 passes through and is slidably connected in the connecting groove, a movable plate 10 is fixed to the bottom end of the discharge box 3, the movable plate 10 is slidably connected in the connecting groove, a spring 11 is fixed to the bottom end of the movable plate 10, the spring 11 is fixed to the connecting groove, a rotating rod 8 is rotatably connected between the inner walls on both sides of the connecting groove, an eccentric block 9 is fixed to the outer wall of the rotating rod 8, a first motor 14 is installed on one side of the mounting frame 1, and the output end of the first motor 14 passes through the mounting frame 1 and is fixed to the rotating rod 8.

[0022] It should be noted that by starting the first motor 14, the first motor 14 drives the rotating rod 8 to rotate, the rotation of the rotating rod 8 drives the eccentric block 9 to rotate, the rotation of the eccentric block 9 drives the movable plate 10 to move up and down, and the movable plate 10 moves up and down to drive the discharge box 3 to move up and down, so that the material falls from the discharge box 3, avoiding some sticky or high-humidity materials from clogging the discharge box 3 and affecting the material discharge.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a dust collecting mechanism 4 is provided at the top of the mounting frame 1. The dust collecting mechanism 4 includes a fixing frame 401 fixed at the top of the mounting frame 1. A connecting piece 402 is fixed between the inner walls of both sides of the fixing frame 401. The connecting piece 402 has a cavity inside and a plurality of dust collecting covers 403 are fixedly connected at the bottom end. A collecting box 405 is fixed at the top of the mounting frame 1. A dust collecting pipe 404 is fixedly connected at the top of the connecting piece 402. The dust collecting pipe 404 is fixedly connected to the collecting box 405. A collecting box 406 is plugged into one end of the collecting box 405. The collecting box 406 is provided with a plurality of filter holes. A connecting frame 407 is fixedly connected to one side of the collecting box 405. A dust collecting fan 408 is rotatably connected in the connecting frame 407. After the rotating rod 8 passes through the mounting frame 1, a driving wheel 5 is fixed to the outer wall thereof. A fixing rod is fixed to one side of the dust collecting fan 408. After the fixing rod passes through the connecting frame 407, a driven wheel 6 is fixed to the outer wall thereof. A belt 7 is provided between the driving wheel 5 and the driven wheel 6.

[0024] It should be noted that the rotation of the rotating rod 8 drives the driving wheel 5 to rotate, the rotation of the driving wheel 5 drives the belt 7 to move, and the movement of the belt 7 drives the driven wheel 6 to rotate, thereby causing the dust suction fan 408 to rotate, and the dust generated during the unloading process is sucked into the collection box 406 through the dust suction hood 403, the connecting piece 402, and the dust suction tube 404 for collection, so as to prevent the dust during the unloading process from spreading in the air and affecting the surrounding air quality. When the collected dust needs to be cleaned later, the collection box 406 can be pulled out and the dust can be taken out of the collection box 406.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, the limiting plate 13 is rotatably connected between the inner walls of both sides of the material box 3, and a second motor 15 is fixed to one side of the material box 3.

A handle is installed at one end of the collection box 406, and a conveyor belt 12 is arranged between the inner walls of both sides of the mounting frame 1. A controller 2 is installed on the other side of the mounting frame 1, and the controller 2 is electrically connected to the first motor 14 and the second motor 15.

[0026] It should be noted that the second motor 15 is started by the controller 2, and the second motor 15 drives the limiting plate 13 to rotate, thereby adjusting the amount of material discharged to avoid the accumulation of too much material on the conveyor belt 12, which affects the subsequent magnetic separation work of the magnetic separator. The conveyor belt 12 belongs to the prior art and will not be elaborated on here.

[0027] Working principle: The first motor 14 is started through the controller 2, and the first motor 14 drives the rotating rod 8 to rotate, and the rotation of the rotating rod 8 drives the eccentric block 9 to rotate, and the rotation of the eccentric block 9 drives the movable plate 10 to move up and down, and the movable plate 10 moves up and down to drive the discharge box 3 to move up and down, so that the material falls from the discharge box 3 to avoid some sticky or humid materials from blocking the discharge box 3 and affecting the material discharge. In addition, the rotation of the rotating rod 8 drives the driving wheel 5 to rotate, and the rotation of the driving wheel 5 drives the belt 7 to move, and the movement of the belt 7 drives the driven wheel 6 to rotate, so that the dust suction fan 408 rotates, and the dust generated during the discharge process is sucked into the collection box 406 through the dust suction hood 403, the connecting piece 402, and the dust suction pipe 404 for collection, so as to avoid dust spreading in the air and affecting the surrounding air quality. The material falling from the limiting plate 13 falls on the conveyor belt 12 and is transported by the conveyor belt 12, which is convenient for the subsequent magnetic separation of the material.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
