Detailed ways

In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in Figures 1-4, an intelligent coal mine separator includes a vibrating box 1 and a main screen 2 that is slanted and movably arranged in the vibrating box 1. The main screen 2 includes arc baffles arranged in a linear array. 21. Support plates 22 are arranged in an array between the arc-shaped baffles 21, and each two support plates 22 are matched with each other to form a feeding chute 24. The bottoms of the arc-shaped baffles 21 are respectively The movable rods 23 are symmetrically arranged, and the movable rods 23 are respectively provided with moving rods 4 , and the main screen 2 is driven to vibrate so that the shifting rods 4 are respectively moved into the feeding chute 24 . The main screen 2 installed in the vibrating box 1 is tilted and moved, so that the main screen 2 can perform preliminary screening on the ore entering the vibrating box 1, so as to prevent the heavier ore from causing damage to subsequent screens. At the same time, the main screen 2 includes arc baffles 21 arranged in a linear array, and support plates 22 are arranged in an array between the arc baffles 21, and every two support plates are matched between every two arc baffles 21. 22 to form the feeding chute 24, and the feeding chute 24 is used for preliminary screening. The bottom of the arc baffle 21 is symmetrically provided with movable rods 23, and the movable rods 23 are respectively provided with moving rods 4. Therefore, when the main screen 2 is subjected to When the vibration is driven, it will carry the lever 4 in the movable rod 23 to move in the feeding chute 24 respectively, so as to prevent the material from accumulating in the feeding chute 24 and block the feeding chute 24, and at the same time, it can disperse the material and make it Evenly fall on the subsequent screen.

Specifically, the main screen 2 in the above technical solution is driven to vibrate, and the driven vibration mode can be a vibration table, or a connecting rod, a motor and an eccentric wheel; or a vibration mode known to those skilled in the art can be .

As shown in FIG. 3 , as a further technical solution provided by the present invention, in order to enable the lever 4 to vibrate with the movable rod 23 to move the material in the feeding chute 24, the movable rod 23 is respectively provided with a knocking block 42. One end of the knocking block 42 is respectively fixedly installed with the first spring 43, and the other end of the first spring 43 is fixedly installed on the movable rod 23, the lever 4 is slidably arranged on the movable rod 23, and the lever 4 is relatively knocked One end of the block 42 is fixedly installed with the second spring 41, and the other end of the second spring 41 is fixedly installed on the movable rod 23, so when the movable rod 23 is driven to vibrate with the main screen 2, it makes the knocking block 42 respectively The arc baffle 21 vibrates to squeeze the first spring 43, and when the arc baffle 21 slides to the other side, the arc baffle 21 carries the knocking blocks 42 on the first spring 43 to move, while the first spring 43 moves. A spring 43 releases the accumulating force so that the knocking block 42 hits the lever 4 , and the second spring 41 is pressurized and accumulating, so that the lever 4 slides in the feeding chute 24 , and moves and disperses the feeding chute 24 When the arc-shaped baffle 21 slides back again, the second spring 41 releases the stored force, so that the lever 4 rebounds and resets, and the knocking blocks 42 vibrate with the arc-shaped baffle 21 again to squeeze The first spring 43 is charged.

Further, in order to distinguish and sort coal mines of different volumes, the vibrating box 1 is provided with a fine mesh screen 3 inclined and sliding, and the fine mesh screen 3 is located below the main screen 2, and the fine screen 3 is parallel to the main screen. At the same time, the fine mesh screen 3 performs secondary screening for the coal mine screened by the main screen 2. The vibrating box body 1 is located below the fine mesh screen 3 and is provided with a collection box 12. The collection box 12 is connected to the fine mesh screen 3. The fine coal mine after screening is collected.

Further, in order to collect the remaining coal mines after the fine screen 3 and the main screen 2 are screened, in the vibrating box 1, a coarse ore box is movably placed on the lower side of the main screen 2 and the fine screen 3 respectively. 14 and the fine ore box 13, the coarse ore box 14 collects the large-volume coal mines screened by the main screen 2, the fine ore box 13 collects the medium-volume coal mines screened by the fine mesh screen 3, and the finer coal mines pass through the fine mesh.
