[0020] Specifically, when carrying out magnetic separation work, the material is sent to the roll leather 105 through the feed slot 106, the metal mineral is adsorbed through the limiting rod 108 in the roll leather 105, other impurities fall into the impurity groove 107 under the action of inertia and are separated, the metal mineral adsorbed by the roll leather 105 falls to the collection frame 111 through gravity when moving below the roll leather 105, because the magnetic force of the limiting rod 108 is insufficient to continue adsorbing the metal mineral, so part of the metal mineral falls to the collection frame 111 through gravity, and in this process, part of the material is adhered to the roll leather 105, and the roll leather 105 continues to rotate, so that after a long time of work, there are more impurities on the roll leather 105, so that the adsorption force on the surface thereof decreases, and interference with the feed slot 106 and the impurity groove 107 occurs, and the roll leather 105, the feed slot 106 and the impurity groove 107 are damaged.

[0021] When the impurities adhered to the roll leather 105 are more or the metal mineral collected in the collection frame 111 is more after being used for a period of time, the sliding frame 109 is controlled to slide to the left on the bottom plate 101, so as to drive the collection frame 111 to move to the left, so that the cleaning frame 112 on the collection frame 111 contacts the roll leather 105, the impurities on the roll leather 105 are scraped off and fall into the cleaning frame 112 for collection through the cooperation of the rotation of the roll leather 105 and the cleaning frame 112.

[0022] Specifically, a set of connecting shafts 114, upper connecting rods 115, lower connecting rods 116, arc-shaped push rods 117, arc-shaped springs 118 and intermediate connecting rods 119 are arranged on both sides of the collecting frame 111, when the metal minerals in the collecting frame 111 need to be removed and collected, the upper connecting rods 115 are controlled to rotate around the axis of the connecting shafts 114, the upper connecting rods 115 drive the lower connecting rods 116, the lower connecting rods 116 drive the baffle plates 113 to rotate around the axis of the connecting shafts 114, so that the baffle plates 113 no longer block the openings at the left end of the collecting frame 111, the metal minerals slide out through the inclined surface at the bottom of the collecting frame 111 and fall through the openings at the left end of the collecting frame 111 and are collected by the external storage box.

[0023] As shown in Figure 3 and Figure 4 , the slide frames 109 are fixedly provided with pull rods 110. Specifically, the slide frames 109 on both sides are controlled to slide on the bottom plate 101 through the pull rods 110.

[0024] The upper connecting rods 115 are fixedly provided with arc-shaped push rods 117, the arc-shaped push rods 117 are slidingly arranged on the collecting frame 111, the arc-shaped push rods 117 are sleeved with arc-shaped springs 118, and the arc-shaped springs 118 are fixedly connected with the upper connecting rods 115 and the collecting frame 111.

[0025] Specifically, when the upper connecting rods 115 rotate, the upper connecting rods 115 push the arc-shaped push rods 117 to slide on the collecting frame 111 and compress the arc-shaped springs 118 on the arc-shaped push rods 117, when the metal minerals in the collecting frame 111 no longer need to be removed, the collecting frame 111 is controlled to reset, the upper connecting rods 115 lose the pushing force, and the upper connecting rods 115, the lower connecting rods 116, the arc-shaped push rods 117 and the baffle plates 113 are pushed to reset under the action of the arc-shaped springs 118, so that the baffle plates 113 reseal the openings at the left end of the collecting frame 111.

[0026] The upper connecting rods 115 are rotatably provided with intermediate connecting rods 119, the intermediate connecting rods 119 are rotatably provided with discharge push plates 120, the discharge push plates 120 are slidingly provided with discharge sliding rods 121, the discharge sliding rods 121 are fixedly arranged on the collecting frame 111, the discharge sliding rods 121 are sleeved with discharge springs 122, and the discharge springs 122 are fixedly connected with the discharge sliding rods 121 and the collecting frame 111.

[0027] Specifically, by controlling the collection frame 111 to slide to the left, the discharge push plate 120 is close to and contacts 123, in this process, the discharge push plate 120 will first contact 123, so that the discharge push plate 120 is fixed when the collection frame 111 continues to move, the discharge slide rod 121 is pushed to slide on the discharge push plate 120, and the discharge spring 122 is compressed, the intermediate connecting rod 119 pushes the upper connecting rod 115 to rotate around the axis line of the connecting shaft 114 and pushes the arc-shaped push rod 117, so as to control the shutter 113 to open.

[0029] Specifically, by controlling the pull rod 110 to move to the left, the slide 109 is pulled to slide to the left on the bottom plate 101, the slide 109 drives the collection frame 111 to move, when the opening at the left end of the collection frame 111 moves to the opening at the left end of the bottom plate 101, the discharge push plate 120 will contact the limiting rod 108, so that when the collection frame 111 continues to move to the left, the discharge push plate 120 contacts the limiting rod 108, the intermediate connecting rod 119 pushes the upper connecting rod 115, and the shutter 113 is driven to open, at this time, the metal mineral in the collection frame 111 slides out through the gap opened by the shutter 113, and falls through the opening at the left end of the bottom plate 101.110 can be connected with an external control device, such as a cylinder, and is linked with 106 to control, when the magnetic separation of metal minerals is carried out for a period of time, in order to avoid that the impurities on 105 are too much to affect the magnetic separation effect, and to avoid that the metal material in 111 is too much to be inconvenient to remove, it is necessary to remove the material in advance. At this time, the feeding of 106 is stopped, the movement of 110 is controlled by the external control device, so as to drive 111 to move out and remove the metal material in 111.
