Abstract
A coal cutting chain comprises a middle guide gear, a rivet, a connecting plate and a gear piece, wherein the middle guide gear is located in the middle, the connecting plate and the gear piece are respectively arranged on two sides, and are connected through the rivet, the connecting plate and the gear piece are arranged in intervals, a sealing ring is sleeved on the rivet between the middle guide gear and the connecting plate or the gear piece, the gear piece is composed of a left flat gear piece, a left bending gear piece, a right flat gear piece and a right bending gear piece, the left flat gear piece and the left bending gear piece are arranged on one side of the middle guide gear in intervals, and the right flat gear piece and the right bending gear piece are arranged on the other side of the middle guide gear in intervals. The gear piece in the coal cutting chain is provided with a hard alloy cutter head, the embedded angles of the flat gear pieces and the bending gear pieces are different, the saw seam is wide, and the coal cutting chain is not easy to be blocked in soft mine layer of coal or mud.
Description
Technical field
The utility model relates to portable special-purpose saw, particularly a kind of coal chain of cutting.
Background technology
Portable chain saw is a kind of very convenient and powerful portable instrument, has the ability of replaceable chain.But the chain of common portable chain saw only is fit to sawmilling material or materials similar, and is then unable to do what one wishes for soft ore beds such as coal, mud.
The utility model content
For remedying above-mentioned deficiency, the utility model provide a kind of can saw soft ore beds such as coal or mud cut the coal chain.
The utility model is cut the coal chain, leads tooth, rivet, brace and gear piece in comprising, in lead in the middle of tooth places, both sides are respectively equipped with brace and gear piece, connect with rivet, brace and gear piece are spaced.
The utility model is cut the coal chain, wherein: lead in described on the rivet between tooth and brace or the gear piece and be with sealing ring.
The utility model is cut the coal chain, and wherein: described gear piece comprises left flat gear piece, the curved gear piece in a left side, right flat gear piece and right curved gear piece, leads tooth one side during the curved gear piece in a left flat gear piece and a left side is placed in, and is spaced; Lead the tooth opposite side during right flat gear piece and right curved gear piece are placed in, be spaced.
The utility model is cut the coal chain, is embedded with alloy saw blade on the gear piece, and flat gear piece and curved gear piece to inlay angle different, saw kerf is wide, is difficult for being stuck in soft ore beds such as coal or mud.
Description of drawings
Fig. 1 is the schematic diagram that the utility model is cut the coal chain;
Fig. 2 is the exploded view that the utility model is cut the coal chain.
The specific embodiment
Below in conjunction with embodiment the utility model is cut the more detailed explanation of coal chain row culture.
Fig. 1 is the schematic diagram that the utility model is cut the coal chain, and Fig. 2 is its exploded view.
The utility model is cut the coal chain, lead tooth 5, rivet 6, brace 8 and gear piece in comprising, gear piece is divided into left flat gear piece 1, the curved gear piece 2 in a left side, right flat gear piece 3 and right curved gear piece 4, is embedded with carbide bit on the gear piece, it is different to inlay angle on flat gear piece and the curved gear piece, and curved gear piece is all oblique outward.
In lead tooth 5 and be triangle, in the middle of placing, both sides are respectively equipped with brace 8 and gear piece, the saw sword direction of gear piece and in to lead the triangular apex direction of tooth 5 opposing, connect into chain with rivet 6, rivet is a movable axis for 6 pages.In lead on the rivet 6 between tooth 5 and brace 6 or the gear piece and be with sealing ring 7, prevent that powder from leading on the movable axis of tooth 5 in entering.
Brace 8 and gear piece are spaced.Lead tooth 5 one sides during the curved gear piece 2 of a flat gear piece 1 in a left side and a left side is placed in, be spaced; Lead tooth 5 opposite sides during right flat gear piece 3 and right curved gear piece 4 are placed in, be spaced, the gear piece dislocation of both sides is arranged.
