Detailed description of the invention
As shown in Figure 1, 2, first embodiment of the present utility model, a kind of railway ballast excavates rake teeth, comprise handle of a knife 1, hard alloy wear resistant parts 2 and carbide bit 3, the head of described handle of a knife 1 has neck 1-2 and front end face 1-1, and described hard alloy wear resistant parts 2 is fixedly connected on neck 1-2, and described carbide bit 3 is fixedly connected on front end face 1-1, the end face of described hard alloy wear resistant parts 2 exceeds the front end face 1-1 of handle of a knife 1, and the handle body of described handle of a knife 1 has latch mounting groove 1-3.
As shown in Figure 1, 2, the neck 1-2 of described hard alloy wear resistant parts 2 and handle of a knife 1 is for weld or interference is connected, and the front end face 1-1 of described carbide bit 3 and handle of a knife 1 is for welding.
As shown in Figure 1, 2, the as a whole annulus of described hard alloy wear resistant parts 2.
As shown in Figure 1, 2, the outer peripheral face of described hard alloy wear resistant parts 2 is with one or more circumferential stress groove 2-1.
As shown in Figure 2, the mounting groove 1-3 on the handle body of described handle of a knife 1 is circumferential groove in its end portion.Corresponding, digger chain 5 is processed a pin hole 5-1 run through, the center line of this pin hole 5-1 with the hole of placing handle of a knife 1 tangent and with handle of a knife 1 central axis, in the latch mounting groove 1-3 and pin hole 5-1 of above-mentioned two pairings, insert latch 4 fix railway ballast and excavate rake teeth.
As shown in Figure 1, 2, the outer peripheral face of described hard alloy wear resistant parts 2 is with one or more circumferential stress groove 2-1.It can hard alloy wear resistant parts 2 because of shock loading cracked time fracture position can be limited in the position of stress groove 2-1, effectively prevent the cracked of the other side of stress groove 2-1.Railway ballast excavates rake teeth and adopts after latch 4 is connected with digger chain 5, and rake teeth can rotate around center line when excavation, prevents eccentric wear, while can also dismounting easily, improve workman's working strength.
In the present embodiment; hard alloy wear resistant parts 2 can protect the head of handle of a knife 1 effectively; improve handle of a knife 1 head abrasion resistance; the part exceeding the hard alloy wear resistant parts 2 of the front end face 1-1 of handle of a knife 1 can protect the surrounding of carbide bit 3 effectively; thus protect railway ballast to excavate the scope of operation of rake teeth on the whole, improve the rake teeth life-span.
As shown in Figure 3,4, the second embodiment of the present utility model, described hard alloy wear resistant parts 2 is spliced by two or more overall annulus, can be divided into several sections in the axial direction.Other structures are with the first embodiment.
As shown in Figure 5,6, the 3rd embodiment of the present utility model, the annulus that described hard alloy wear resistant parts 2 is made up of two panels or the above tile of two panels.The hard alloy wear resistant parts 2 of tile composition adopts with handle of a knife 1 and is welded and fixed.Other structures are with the first embodiment.
Consider that carbide alloy differs comparatively large with the linear expansion coeffcient of fertile material, hard alloy wear resistant parts 2 be overall circular time, the ability that its containing is expanded with heat and contract with cold is lower; In the present embodiment, be multi-disc tile by segmentation hard alloy wear resistant parts 2, reduce the bonding area of single carbide alloy tile, thus reduce welding difficulty, ensure product quality.
As shown in Fig. 7,8,9, the 4th embodiment of the present utility model, described hard alloy wear resistant parts 2 is a semicircular ring tile.Process a corresponding semicircular neck 1-2 at the head of handle of a knife 1, wherein the end face of hard alloy wear resistant parts 2 exceeds the front end face 1-1 of handle of a knife 1, and hard alloy wear resistant parts 2 and carbide bit 3 are by being welded to connect.
As shown in Figure 7,8, the latch mounting groove 1-3 on the handle body of described handle of a knife 1 is the semicircle straight trough perpendicular with the axis direction of handle of a knife 1.Digger chain 5 is processed a pin hole 5-1 run through, the center line of this pin hole 5-1 with the hole of placing handle of a knife 1 tangent and with handle of a knife 1 central axis, in the latch mounting groove 1-3 and pin hole 5-1 of above-mentioned two pairings, insert latch 4 fix railway ballast and excavate rake teeth.After railway ballast excavation rake teeth is fixing, the side at hard alloy wear resistant parts 2 place is the scope of operation.
In this embodiment, the latch mounting groove 1-3 that railway ballast excavates on rake teeth changes the semicircle straight trough perpendicular with the axis direction of handle of a knife 1 into by the circumferential groove in its end portion in embodiment one, after latch 4 is fixing, this railway ballast excavates rake teeth and just cannot rotate, and hard alloy wear resistant parts 2 side is as scope of operation continuous firing.After adopting this embodiment, reduce the quality of carbide alloy, reduce cost; Reduce bonding area, successfully manage the weld defect caused because carbide alloy is different from the welded steel coefficient of expansion; Enhance handle of a knife intensity.
