Example 2

The utility model discloses a rotation type is from trembling grey grate comprises base 1, circular grate base 2 and grate crossbeam 3, base 1 on open and to have grey round hole 4 that falls, be equipped with the riding wheel groove 5 more than three on the base 1 of 4 ring weeks of grey round hole that falls, all install riding wheel 6 in riding wheel groove 5, have outside convex annular in the lower part outside of circular grate base 2 and scatter along 19, the annular is scattered along 19 lower surface seat on riding wheel 6. An annular toothed belt 7 is arranged on the outer periphery of the lower part of the annular loose edge 19, the annular toothed belt 7 is meshed with a power output end gear 9 of a gearbox 8 fixed on the base 1, and the gearbox 8 is in transmission connection with a speed reducing motor 10 fixed on the base 1; an annular rolling groove 18 is arranged at the position where the annular scattering edge 19 abuts against the riding wheel 6. The riding wheel 6 is matched with the annular rolling groove 18, and the speed reducing motor 10 drives the gearbox 8 to drive the annular toothed belt 7 through the gear 9, so that the circular fire grate base 2 can rotate by taking the axis as the axis.

More than three grate beams 3 are arranged on the upper opening of a circular grate base 2 at equal intervals, ear plates 11 are fixed in the middle of the lower surfaces of the grate beams 3, the ear plates 11 are hinged to connecting rods 12, swing arms 13 are fixed to one ends of the lower surfaces of the middle grate beams 3, swing arm baffles 14 are fixed to the inner walls of ash falling round holes 4, the length of each swing arm 13 is larger than the distance from the lower surface of each grate beam 3 to each swing arm baffle 14, and when the circular grate base 2 rotates under the driving of an annular toothed belt 7, the swing arms 13 rotate to the positions of the swing arm baffles 14, so that the grate beams 3 are inclined to swing left and right. The lower surface of one end of the middle grate beam 3 is fixed with a swing arm 13, so that the swing effect of all grate beams can be driven to reach the best, smooth and unsmooth.

Meanwhile, arc-shaped grooves 15 which are in one-to-one correspondence with the end parts of the grate beams 3 are formed in the inner side of the top end of the circular grate base 2, the transverse position and the longitudinal position of each grate beam 3 are limited, deviation is avoided, when the circular grate base 2 rotates to enable the grate beams 3 to swing left and right, the cross sections of two ends of each grate beam 3 are semicircular, the cross sections of middle sections of the two ends of each grate beam 3 are of square structures, and the cross sections of the two ends of each grate beam 3 are of semicircular structures, so that the grate beams can rotate in the arc-shaped grooves 15 at the positions smoothly and cannot be.
