An accommodating room of a machine body is divided into an inner space and an outer space. Two sides of the conveyor belt assemble with chains each having chain links. Each chain link has a first opening facing the inner space and a second opening facing the outer space. A guiding block is arranged in the inner space. The guiding block has a bottom surface, a blocking face, and a guiding gap. The bottom surface faces to the conveyor belt. The guiding gap lies at one side of the blocking face and communicates with the chain links. Therefore, metal chips are stopped by the blocking face and are moved to the guiding gap, then drop to the outer space via the chain links. ## Claims ### Claim 1 A metal chip conveyor having an internal chip removal structure, comprising: a machine body, having a casing, an accommodating room being enclosed by the casing; an endless conveyor belt, disposed in the accommodating room and driven by a drive device; the accommodating room defining an inner space enclosed by the conveyor belt and an outer space outside the conveyor belt; two sides of the conveyor belt being provided with a pair of chains each having a plurality of chain links, the chain links each having a first opening facing the inner space and a second opening facing the outer space; two support bushes, disposed at opposite sides of the casing and extending toward the accommodating room; the conveyor belt passing around the two support bushes and being supported by the two support bushes, the support bushes covering the first openings of the chain links corresponding in position to the support bushes when the conveyor belt is running; and a guiding block, arranged in the inner space, the guiding block having a bottom surface, a blocking face and a guiding gap, the bottom surface faced to the conveyor belt, the guiding gap lied at least one side of the blocking face and communicated with the chain links. ### Claim 2 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein the opposite sides of the casing are provided with two detachable cover plates, and the two support bushes are disposed on the two cover plates, respectively. ### Claim 3 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein the support bushes each has a guide section to hold against the conveyor belt, and the guide section covers the first openings of the chain links corresponding in position to the guide section. ### Claim 4 (depends on 3) The metal chip conveyor as claimed in claim 3, wherein the guide section has a curved contact surface to hold against the conveyor belt. ### Claim 5 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein the conveyor belt is provided with a plurality of spaced crossbars extending outward toward the outer space. ### Claim 6 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein at least one end of the guiding block is connected to the casing. ### Claim 7 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein the blocking face is vertical to the bottom surface. ### Claim 8 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein at least one corner of the guiding block is inclined sliced off for forming the guiding gap. ### Claim 9 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein the bottom surface is closely bordered to the conveyor belt. ### Claim 10 (depends on 1) The metal chip conveyor as claimed in claim 1, wherein a rear end of the casing extends a gathering space communicating with the outer space.
