[0002] The mechanical grate incinerator is composed of grate pieces stacked in a certain pattern to form a grate bed. The grate pieces are divided into movable grate pieces and fixed grate pieces. The movable grate pieces and the fixed grate pieces move relative to each other, driving the garbage and fuel on the grate bed to move together, and the fuel burns the garbage.

[0003] A Chinese patent with announcement number CN207049943U discloses a high-pressure loss grate plate structure device for a waste incinerator, which includes a fixed grate plate and a movable grate plate. The fixed grate plates and the movable grate plates are arranged alternately. The base of the movable grate plate moves back and forth by relying on a driving unit, so that the movable grate plate reciprocates from bottom to top, thereby realizing the movement and flipping of garbage.

[0004] During the use of the above technology, the movable grate slices push the garbage down from the upper surface of the fixed grate slices and fall onto the next movable grate slices. Since the garbage is pushed down by the movable grate slices to achieve tumbling, the tumbling effect is poor and accumulation is prone to occur, resulting in poor incineration effect of the garbage thereon, which has shortcomings. Utility Model Content

[0005] In order to realize continuous movement and turning of garbage, the present application provides a reciprocating mechanical grate device with a built-in garbage turning effect.
