The traditional reciprocating fire grate pushes fuel to move forwards through the reciprocating motion of the fire grate segment, and can drive the fuel and the fire grate segment to generate relative motion. However, in the conventional reciprocating grate, the grate segments only reciprocate in situ, the stirring effect on the fuel is very limited, and the fuel is still difficult to be fully combusted.

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1 to 6: a staggered step chain grate between rows comprises a shell, a front shaft 1 and a rear shaft 2 are rotatably supported in the shell, a first front shaft driving sprocket 3, a first front shaft guide smooth wheel 4, a second front shaft driving sprocket 5 and a second front shaft guide smooth wheel 6 are sequentially arranged on the front shaft 1, a first rear shaft guide smooth wheel 7, a first rear shaft driving sprocket 8, a second rear shaft guide smooth wheel 9 and a second rear shaft driving sprocket 10 are sequentially arranged on the rear shaft 2, a first chain is wound on the first front shaft driving sprocket 3 and the first rear shaft guide smooth wheel 7 together, a second chain is wound on the first front shaft guide smooth wheel 4 and the first rear shaft driving sprocket 8 together, a third chain is wound on the second front shaft driving sprocket 5 and the second rear shaft guide smooth wheel 9 together, and a fourth chain is wound on the second front shaft guide smooth wheel 6 and the second rear shaft guide smooth wheel 10 together, a plurality of first grate mechanisms distributed at equal intervals are supported between the first chain and the third chain, a plurality of second grate mechanisms distributed at equal intervals are supported between the second chain and the fourth chain, the front shaft 1 and the rear shaft 2 are respectively driven by a set of independent driving mechanism,
the first grate mechanism and the second grate mechanism have the same structure,
the first grate mechanism comprises angle steel 11, two ends of the angle steel 11 are fixedly connected with a chain, a support frame 12 is connected onto the angle steel 11, a plurality of front connecting seats 13 distributed at equal intervals are arranged on the front side of the support frame 12, a plurality of rear connecting seats 14 distributed at equal intervals are arranged on the rear side of the support frame 12, the front connecting seats 13 and the rear connecting seats 14 are distributed in a staggered manner in the length direction of the support frame 12, grate sheets 15 are hinged onto the front connecting seats 13 and the rear connecting seats 14, the grate sheets 15 face the front of the support frame 12, a plurality of air holes 16 distributed in an array manner are formed in the surface of each grate sheet 15,
in a pair of adjacent first grate mechanism and second grate mechanism, grate segments 15 in the rear grate mechanism are lapped on corresponding grate segments 15 in the front grate mechanism.
The working process of the inter-row staggered step type chain grate of the embodiment of the utility model is as follows: when in work, the front shaft 1 and the rear shaft 2 are driven by respective driving mechanisms to rotate alternately, the time intervals of the rotation of the front shaft and the rear shaft are the same, the rotation angles of the front shaft and the rear shaft are the same,
when the front shaft 1 rotates, the first front shaft driving sprocket 3 and the second front shaft driving sprocket 5 on the front shaft 1 can drive the paired first chain and third chain to move, and further drive all first grate mechanisms connected between the first chain and the third chain to perform stepping advancing action; in the process, the first chain and the first rear shaft guide smooth wheel 7 slip, and the third chain and the second rear shaft guide smooth wheel 9 slip, namely the front shaft 1 does not drive the rear shaft 2 to move when rotating;
similarly, when the rear shaft 2 rotates, the first rear shaft driving sprocket 8 and the second rear shaft driving sprocket 10 on the rear shaft 2 drive the paired second chain and fourth chain to move, so as to drive all the second grate mechanisms connected between the second chain and the fourth chain to perform stepping type advancing action; in the process, the second chain slips between the first front shaft guide smooth wheel 4 and the fourth chain slips between the fourth chain and the second front shaft guide smooth wheel 6, namely the front shaft 1 cannot be driven to move when the rear shaft 2 rotates;
the adjacent first fire grate mechanism and the second fire grate mechanism form a group, in the adjacent fire grate mechanisms, the fire grate segment 15 in the rear fire grate mechanism is lapped on the fire grate segment 15 in the front fire grate mechanism (the material conveying direction is the front),
for convenience of describing the action process of different grate mechanisms in the grate in the working process, the following examples are given: taking two groups of adjacent grate mechanisms as an example, the two groups of adjacent grate mechanisms and the four grate mechanisms are respectively marked as a No. 1 grate mechanism, a No. 2 grate mechanism, a No. 3 grate mechanism and a No. 4 grate mechanism, in an initial state, all grate segments 15 in the No. 1 grate mechanism are lapped on corresponding grate segments 15 in the No. 2 grate mechanism, and all grate segments 15 in the No. 2 grate mechanism are lapped on corresponding grate segments 15 in the No. 3 grate mechanism, at the moment, the No. 1 grate mechanism is closer to the No. 2 grate mechanism, the No. 3 grate mechanism is closer to the No. 4 grate mechanism, and the No. 2 grate mechanism is relatively farther from the No. 3 grate mechanism; because a plurality of fire grate segments 15 in one fire grate mechanism are originally respectively connected on the front connecting seat 13 and the rear connecting seat 14, the adjacent fire grate segments 15 in the same fire grate mechanism are distributed in a staggered manner;
when the fire grate works, the No. 2 and No. 4 fire grate mechanisms move forwards for a unit distance, the No. 1 and No. 3 fire grate mechanisms are not moved, namely the No. 2 and No. 4 fire grate mechanisms are respectively far away from the No. 1 and No. 3 fire grate mechanisms, so that the fire grate pieces 15 in the No. 1 and No. 3 fire grate mechanisms naturally swing due to the position change of a support, and the swinging action of all the fire grate pieces 15 in the No. 1 and No. 3 fire grate mechanisms is realized; on the same principle, in the process of No. 2 and No. 4 movements, the grate segments 15 swing along with the movements of the grate segments;
after the No. 2 and No. 4 fire grate mechanisms stop moving, the No. 1 and No. 3 fire grate mechanisms move forwards for a unit distance, so that the distances between the No. 1 and No. 4 fire grate mechanisms and the No. 2 and No. 4 fire grate mechanisms are drawn again, and similarly, all the fire grate segments 15 in all the fire grate mechanisms naturally swing due to the position change of the supports;
that is, when the fire grate works, all the fire grate segments 15 drive the combustion objects to move in a stepping mode, and in the moving process, all the fire grate segments 15 regularly swing each time when moving, so that the purposes of crushing the combustion objects and fully combusting the combustion objects are achieved.
Meanwhile, all the fire grate segments 15 are in periodic circulating motion, so the fire grate segments 15 can be fully cooled in the return stroke process, and the problem that the fire grate segments in the traditional reciprocating fire grate are damaged due to high temperature is solved.
