Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present embodiments more clearly, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 4, in an embodiment of the present invention, a bucket tooth applied to an excavator includes a tooth holder 1, a tooth tip 2 and a wear-resistant sleeve 3, wherein a fixing column 31 is outwardly disposed inside the wear-resistant sleeve 3; the tooth point 2 comprises two tooth point bodies 21 which are symmetrically arranged, the large end ends of the two tooth point bodies 21 are connected to the tooth base 1 through bolts (the bolts are not shown in the attached drawings), the wear-resistant sleeve 3 is sleeved on the tip ends of the two tooth point bodies 21, and a clamping groove 211 which is matched with the fixing column 31 and used for clamping the fixing column 31 is arranged between the tip ends of the two tooth point bodies 21.

In this embodiment, the outer end of the fixing column 31 integrally protrudes to form a limiting block 32, and a limiting groove 212 matched with the limiting block 32 is formed between the two tooth tip bodies 21, so that the wear-resistant sleeve 3 can be effectively prevented from falling off under the matching of the limiting block 32 and the limiting groove 212. The limiting block 32 is preferably spherical, the spherical surface is smoother and has no edges and corners, and scraping between the limiting block 32 and the limiting groove 212 is reduced. In addition, if the value obtained by subtracting the diameter of the limiting block 32 from the diameter of the fixed column 31 is smaller than 1mm, the limiting function between the limiting block 32 and the limiting groove 212 is not obvious; if the value obtained by subtracting the diameter of the fixed column 31 from the diameter of the limiting block 32 is greater than 5mm, the tips of the two tooth point bodies 21 are difficult to insert into the wear-resistant sleeve 3, and therefore the diameter of the limiting block 32 is 1-5 mm larger than the diameter of the fixed column 31, which is more suitable, preferably 3 mm.

In this embodiment, two equal integrative protrusion in inboard of prong body 21 has reference column 213, the equal integrative sunken constant head tank 11 that has and reference column 213 assorted in both sides of prong 1 under the cooperation of reference column 213 and constant head tank 11, can improve two the assembly precision of prong body 21 and the fastness of being connected between two prong bodies 21 and the prong 1.

In this embodiment, the outer sides of the two tooth tip bodies 21 are provided with receiving holes 214 for receiving the ends of bolts, and the receiving holes 214 can protect the ends of the bolts to prevent the bolts from colliding with the ground or rock.

In this embodiment, V-shaped ribs 215 are integrally protruded on the outer sides of the two tooth tip bodies 21, and the V-shaped ribs 215 improve the strength of the tooth tip body 21, thereby prolonging the service life thereof.

In this embodiment, the accommodating hole 214, the positioning column 213, the positioning groove 11 and the bolt are coaxially arranged, so that the volumes of the two tooth tip bodies 21 can be greatly reduced.

The working principle is as follows: firstly, the two tooth point bodies 21 are combined on the tooth base 1, the positioning columns 213 are ensured to be inserted into the positioning grooves 11, the positioning precision of the two tooth point bodies 21 is ensured, and then bolts are inserted (not screwed down at first); then, the tips of the two tooth tip bodies 21 are inserted into the wear-resistant sleeve 3, so that the clamping groove 211 is ensured to be clamped on the fixing column 31, and the limiting groove 212 is ensured to be matched with the limiting block 32, thereby preventing the wear-resistant sleeve 3 from falling off; finally, the bolts are tightened, at the moment, the two tooth tip bodies 21 are installed and fixed on the tooth holder 1 through the bolts, and the wear-resistant sleeve 3 is installed and fixed on the tips of the two tooth tip bodies 21, so that the tips of the two tooth tip bodies 21 are protected. When the wear-resistant sleeve 3 is worn out, the old wear-resistant sleeve 3 can be detached by unscrewing the bolt, and the new wear-resistant sleeve 3 is independently replaced, so that the later maintenance cost is greatly reduced.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
