Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

As shown in fig. 1-3, the embodiment of the application provides a bucket tooth, including bucket tooth body 1, reinforcing part 2, wherein, more sharp one end is tooth point 101 in the both ends of bucket tooth body 1, and the other end is the tooth root and nearby be equipped with be used for with bucket interference fit connection's mounting hole 5, bucket tooth body 1 includes along length direction distributed first section and second section, and first section is the part that is close to tooth point 101, and the second section is the part that is close to the tooth root, and reinforcing part 2 at least half surrounds the both sides of distributing in first section along width direction relative distribution to widen and thicken first section. So set up, the bucket tooth body 1 is close to the first section of tooth point 101 and sets up reinforcing part 2, according to the wearing and tearing law that the regional wearing and tearing of both sides of bucket tooth is greater than the regional wearing and tearing in middle, the reinforcing part 2 of partly enclosing is designed to the both sides of bucket tooth body 1, as wear-resisting structure, promote the wear resistance of bucket tooth, after assembling to the scraper bowl, tooth point 101 contacts earlier with the material, then the first half section part of bucket tooth, the both sides regional frequent with the material contact of first section promptly, bear wearing and tearing by reinforcing part 2 like this, the life of extension bucket tooth, the poor, the frequent problem of change of bucket tooth wear resistance among the prior art has been solved.

In a preferred embodiment, at least one of two surfaces of the tooth body 1 which are distributed oppositely along the thickness direction is provided with a guide groove 3, specifically a recess on the first section on the upward surface of the tooth, the guide groove 3 extends to be close to the tooth tip 101 along the length direction, and the two sides of the guide groove 3 are provided with reinforcing parts 2. So set up, the intermediate zone design baffle box 3 of bucket tooth body 1 can make the material quick separation, improves the soil unloading performance of bucket tooth excavation in-process, reduces the excavation resistance, and in addition, another effect of baffle box 3 is at the later stage of bucket tooth wearing and tearing, because it is sunken, both sides, left and right sides all wear back about the first section, also can guarantee that the bucket tooth possess certain cutting angle, the ability of breaking the earth promptly, avoids wearing and tearing the middle stage just to appear grinding the dulling phenomenon, further prolongs the life of bucket tooth.

Further, the peripheral edges of the guide grooves 3 are closed and coherent, namely, the guide grooves 3 are integrally positioned in the upward face of the bucket tooth body 1, the bottoms of the guide grooves 3 comprise cambered surface sections 301 and plane sections 302 tangent to the cambered surface sections 301, and the plane sections 302 are arranged closer to the tooth tips 101 than the cambered surface sections 301. Therefore, after the reinforcing part 2 and the bucket tooth body 1 are gradually worn, the plane section 302 is gradually used as an upward cutting surface of the bucket tooth body 1 so as to ensure the cutting performance of the bucket tooth, and the cambered surface section 301 is far away from the tooth tip 101, so that smooth guiding and discharging of materials in the guide chute 3 are facilitated, and the occurrence of clamping materials is avoided.

In a specific embodiment, the connecting edge 4 is formed between the reinforcing part 2 and the tooth body 1, and the connecting edge 4 is an arc surface, so that the arc surface connecting part is smooth and excessive, can disperse stress, is beneficial to strengthening the structural strength, and can also play a role in guiding materials to a certain extent.

In a more specific embodiment, the ratio of the dimension of the guide chute 3 in the width direction to the dimension of the tooth tip 101 in the width direction is set to be 1:2-1:1.4; and/or the size of the guide groove 3 in the width direction is 60mm to 72mm, and the size of the tooth tip 101 in the width direction is 100mm to 120mm. Specifically, the guide groove 3 may have a width of 66mm and the tooth tip 101 may have a width of 110mm.

In a preferred embodiment, the tooth body 1 is provided as a flat wedge, i.e. the dimension in the thickness direction from the tooth root to the tooth tip 101 is gradually reduced, and the included angle between two surfaces of the tooth body 1 which are relatively distributed in the thickness direction is in the range of 14 ° to 34 °, and may be specifically set to 24 °. In this way, the bucket tooth adopts a flat and wide structure instead of the slender structure in the prior art, the size of the bucket tooth in the width direction is increased, the capability of the bucket tooth for resisting material impact in the excavating process is improved, in addition, the first section of the bucket tooth body 1 is widened, the wear-resistant area of the bucket tooth can be increased, and the wear resistance of the first section of the bucket tooth body 1 is further improved.

Further, the tooth tip 101 is the wedge tip of a wedge block; wherein the ratio of the dimension of the tooth tip 101 in the width direction to the dimension in the thickness direction is 20:1 to 50:1; and/or the dimension of the tooth tip 101 in the width direction is 100mm to 120mm, and the dimension of the tooth tip 101 in the thickness direction is 2mm to 6mm. Specifically, the dimension of the tooth tip 101 in the width direction is 110mm, and the dimension of the tooth tip 101 in the thickness direction is 4mm. Thus, compared with the bucket teeth in the prior art, the tooth tip 101 of the bucket teeth provided by the application is moderately reduced in height, the front end cutting material performance of the bucket teeth is improved, the excavating depth of the bucket teeth is increased, more materials are excavated by the bucket, and the operation efficiency is improved.

In addition, the first section of the bucket tooth body 1 is widened in the width direction, the space between bucket teeth is correspondingly reduced after the bucket teeth are installed on the bucket, the probability that fine materials fall from the gap between the bucket teeth is reduced, and particularly in the stage that the bucket is changed from excavation to lifting, the number of the materials covered by the bucket can be increased by the design, and the excavating efficiency of the machine is improved.

In a more specific embodiment, the ratio of the size of the bucket tooth body 1 corresponding to the side of the guide chute 3, which is close to the tooth tip 101, in the thickness direction to the size of the tooth tip 101 in the thickness direction is 1:6-1:3.3; and/or the size of the bucket tooth body 1 corresponding to the side of the guide groove 3 close to the tooth tip 101 in the thickness direction is 12-20 mm, and the size of the tooth tip 101 in the thickness direction is 2-6 mm. This arrangement is advantageous in ensuring that the guide chute 3 can be used as a cutting surface in the middle and later stages, and can be implemented specifically such that the size of the tooth body 1 corresponding to the side of the guide chute 3 near the tooth tip 101 in the thickness direction is 16mm and the size of the tooth tip 101 in the thickness direction is 4mm.

Further, the depth of the guide groove 3 may be set to 8mm, the dimension in the length direction of the planar section 302 of the guide groove 3 is 58mm, and the chamfer arc radius of the cambered section 301 of the guide groove 3 is 43mm.

As shown in fig. 1, the longitudinal direction is the a direction, the width direction is the b direction, and the thickness direction is the c direction. In addition, all numerical ranges herein include both endpoints.
