SU24513A1 - Chain grate - Google Patents

Description

The invention relates to chain grates with a grate type trowel elements that receive, in addition to the main movement, also transverse movements in order to loosen the fuel.

In the proposed grid, to communicate the grate elements of transverse movements, the latter are supported by bands associated with earrings that receive a rocking movement from the crank mechanism, regardless of the rotation of the drive chain of sprockets; for the purpose of cleaning, the grate elements have a comb shape, and, when the elements move with their free ends along the guides, the teeth of the fixed comb enter into the spaces between the teeth.

In FIG. 1 shows a schematic view of a chain grate from the side; FIG. 2 - front view of the grate; FIG. 3 is a side view of it; FIG. 4 - view of the rear stars of the grille; FIG. 5 - view of the front stars.

The sprockets / driven in motion, each independently of the shafts 2 fixed on the uprights 3 (Fig. 4, 5), set in motion the chain 4, to which the grate elements of the aperture type indicated on the form drawing are suspended two trunnions 5. In the upper part of the grate, in order for the grate elements to move, they form a complex surface for placing fuel on it, as well as to communicate the elements

transverse oscillatory motion (Fig. 3), supporting strips b, hingedly mounted on swinging earrings 7, are placed under them. crankshaft, passes in the center of the hollow shaft 2. Pulleys 12 and 13 serve to bring the sprockets / and fingers of the crank 9, respectively, into rotation. The grate elements a, descend from the rear sprockets / c bands b, take a vertical position. Dumping the ash, the elements below approach the guides 14, take an inclined position and meet on the path a fixed comb 15, the teeth of which pass through the gaps between the teeth of the free ends of the grate elements a having a comb shape (Fig. 2).

In the leading front sprockets, elements a move in curved guides 16 located above the upper parts of the sprockets.

Present invention

Claims (4)

1. Chain grate with swing type grate elements, receiving, in addition to the main movement, also transverse movements in order to loosen the fuel, which is different from those used for telling grate elements and transverse displacements. the elements of the strip 5 associated with the earrings /, which receive oscillatory movements from the crank mechanism 9-10, whose shaft has a rotation, regardless of the rotation of the sprockets /, leading the chain 4 (Fig. 1). 2. In the lattice of claim. 3.In the lattice according to claim. / Application for cleaning the grate elements of the fixed comb / 5, the tooth in which fits into the gaps between the teeth of the elements when the latter are moved by the free ends along the guides 14 (Fig. 2). 4. In the lattice according to claim / application for the grate elements of the guides 16 placed above the upper parts of the front sprockets.
