[0035] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0036] Example 1: A dynamic screen jigging dry selection device, see Figures 1 to 4 , including a jig body 1, a coal bunker 2, a square cone 5, a grid plate 3 and a cover plate 4;
[0037] The coal bunker 2 is arranged in the outer shell of the jig body 1; a plurality of square cones 5 are arranged in the coal bunker 2; a grid plate 3 is arranged at the top of the coal bunker 2; a cover plate 4 is arranged at the top of the outer shell of the jig body 1; wherein a plurality of buffer structures 6 are arranged on the inclined surfaces of the four sides of the square cone 5;
[0038] The buffer structure 6 includes a baffle 601;
[0039] The baffle 601 is arranged obliquely on the outer wall of the inclined surface of the square cone 5 .
[0040] The utility model has the advantage of arranging the baffle plate 601 so that when the gangue and coal clumps roll down the inclined surface of the material cone, they contact the inclined baffle plate 601 and are impacted and decelerated, so that the gangue and coal clumps are impacted and scattered, thereby solving the problem that when the gangue and coal clumps roll down the inclined surface of the material cone, the impact effect on the clumps is not obvious, and the coal falls wrapped in the gangue.
[0041] Specifically, the square cone 5 is hollow, and both the top and bottom planes of the square cone 5 are open, which is conducive to the flow of wind from bottom to top.
[0042] Furthermore, the buffer structure 6 also includes a spring piece A602 and a spring piece B605;
[0043] One end of the spring piece A602 is connected to the top of the high end of the baffle 601, and the other end is connected to the inclined outer wall of the square cone 5; wherein, one end of the spring piece A602 is aligned with the top side of the high end of the baffle 601; one end of the spring piece B605 is connected to the bottom of the high end of the baffle 601, and the other end is connected to the inclined outer wall of the square cone 5.
[0044] The utility model has the advantages that the baffle 601 can swing slightly to buffer and protect the baffle 601 after being hit by the gangue and coal lumps by arranging the spring pieces A602 and B605, and the baffle 601 can rebound and reset.
[0045] Furthermore, the buffer structure 6 also includes a spring piece C603;
[0046] The spring piece C603 is arranged between the bottom side of the baffle plate 601 and the outer wall of the inclined surface of the square cone 5 , and two ends of the spring piece C603 are fixedly connected to the bottom side of the baffle plate 601 and the outer wall of the inclined surface of the square cone 5 , respectively.
[0047] The utility model has the advantage of further enhancing the buffering and rebounding capabilities of the baffle 601 by providing the spring piece C603 .
[0048] It is worth noting that the buffer structure 6 also includes a stop bar 604;
[0049] The blocking bar 604 is fixedly arranged on the top side of the bottom end of the baffle 601; wherein, the blocking bar 604 adopts an inclined trapezoidal structure design.
[0050] The utility model has the advantage that the block 604 is provided, so that the mass that hits the baffle 601 contacts the inclined trapezoidal baffle 604 when rolling down the inclined baffle 601, and the mass changes its angle along the inclined surface of the baffle 604, thereby further dispersing the gangue and coal.
[0051] Working principle: When the coal material fed into the jig body 1 is sorted by the device of the utility model, the gangue falls due to gravity and is discharged from the gangue channel of the jig body 1, and the coal powder is blown through the grid plate 3 by the wind from bottom to top and is blown away by the horizontal wind and transported out. When the gangue and coal mass roll down along the inclined surface of the material cone, it contacts the inclined baffle 601 and is decelerated by impact. Under the bending action of the spring piece A602 and the spring piece B605, the baffle 601 can swing slightly to buffer after being hit by the gangue and coal mass. At the same time, the spring piece C603 is bent by force, further strengthening the buffering and rebounding ability of the baffle 601. When the mass that hits the baffle 601 rolls down along the inclined baffle 601, it contacts the inclined trapezoidal baffle 604, and the mass changes its angle along the inclined surface of the baffle 604, further dispersing the gangue and coal.
