Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses a support 1 and feeder hopper 2, shale shaker 3, vibrating conveyer belt 4 and lamellar rock sediment sorter 5 of installing on support 1, shale shaker 3 is located feeder hopper 2 below, and the side of shale shaker 3 is equipped with coarse sediment feed inlet 6, the tip of vibrating conveyer belt 4 is located coarse sediment feed inlet 6 department, lamellar rock sediment sorter 5 is located vibrating conveyer belt 4's the other end, lamellar rock sediment sorter 5 includes that a bottom is equipped with the baffle 51 of long and thin opening 53.
In order to further distinguish the small rock slag and the fine crushed powder rock slag, the vibrating screen 3 is divided into an upper coarse material vibrating screen 31 and a lower fine material vibrating screen 32, and the coarse slag feed port 6 is positioned on the side surface of the coarse material vibrating screen 31. The coarse material vibrating screen 31 has large screen holes and can screen out broken blocky rock slag and rock powder, the broken blocky rock slag and the rock powder can pass through the coarse material vibrating screen 31 and leak into the lower part, the broken blocky rock slag and the rock powder can be separated by the fine material vibrating screen 32 with small screen holes, the rock powder passes through the fine material vibrating screen 32, and the broken blocky rock slag is left above the fine material vibrating screen 32.
In order to make big rock sediment can get into vibration conveyer belt 4 smoothly through coarse slag feed inlet 6 during the feeding the below of feeder hopper 2 is equipped with swift current cinder board 21, and swift current cinder board 21 sets up the one side of keeping away from vibration conveyer belt 4 in feeder hopper 2 below, is convenient for with the direction at material direction vibration conveyer belt 4 place.
For avoiding the rock sediment to drop when vibrating the transportation on vibrating conveyor belt 4 the both sides of vibrating conveyor belt 4 are equipped with side direction baffle 7, and the row of the convenience rock sediment is led and is collected, and the position that is close to slice rock sediment sorter 5 front end at side direction baffle 7 is equipped with cubic rock sediment slag notch 71, can set baffle 51 to be certain contained angle with vibrating conveyor belt 4 traffic direction, plays the guide effect, with cubic rock sediment direction cubic rock sediment department slag notch 71. The rear end of the lateral baffle 7, which is positioned at the flaky rock slag separator 5, is provided with a flaky rock slag outlet 72, so that the flaky rock slag can be conveniently collected.
Because of the baffle 51 block, even design into the slope structure, can not guarantee the smooth row of cubic rock sediment and lead, the time also can pile up in baffle 51 for a long time, consequently can the inboard position relative with cubic rock sediment slag notch 71 of baffle 51 is equipped with automatic slag pusher 8, automatic slag pusher 8 includes electronic hydraulic stem 81 and installs the push pedal 82 at electronic hydraulic stem 81 tip, and the distance of push pedal 82 apart from vibrating conveyor belt 4 should be a bit more than the height of the slender opening of baffle 51, through the continuous reciprocating motion of control electronic hydraulic stem 81, and push pedal 82 can push the cubic rock sediment towards cubic rock sediment slag notch 71 constantly.
