Description

Technical Field

[0001] The utility model relates to the technical field of bucket teeth, in particular to a casting bucket tooth component. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig materials and load them into transport vehicles or unload them to a stockpile. The bucket is the execution terminal of the excavator's work tasks, and the bucket teeth are located at the end of the excavator's bucket and are the main parts of the excavator that come into contact with the material. During the excavation project, the bucket teeth wedge into the soil at a certain angle, destroying the surface of the material, allowing the bucket to cut the material with less resistance. Therefore, the performance of the bucket teeth directly affects the excavation performance of the excavator bucket and even the excavator. Reducing the excavation resistance of the bucket teeth can effectively improve the excavation efficiency of the excavator.

[0003] In the prior art, for example, the excavator bucket tooth of Chinese patent CN205502114U comprises: a tooth tip (3), wherein the front end of the tooth tip is a trapezoidal structure (1) and the rear end is provided with an arc-shaped acute-angled triangle structure (2) on one side, and both sides of the arc-shaped acute-angled triangle structure are provided with pin holes (4), and the pin holes are connected to the tooth seat through a pin shaft, and the interior of the tooth tip is a hollow structure. The utility model is applied to the field of engineering machinery.

[0004] In the above patent, two parallel tungsten carbide particles are arranged at the front end of the bucket tooth to protect the tooth tip and improve the service life of the bucket tooth. However, the upper and lower surfaces of the bucket tooth are both flat. The flat bucket tooth mainly relies on the sharp angle of the front edge when cutting and digging. When dealing with certain special materials or complex digging environments, such as frozen soil or rocks, the bucket tooth has a large propulsion resistance, which affects the bucket tooth digging efficiency.

[0017] 1. When the cast bucket tooth assembly is in use, the soil is shoveled through the sharp part of the front side of the trapezoidal block. Its sharp front end can be better pushed into the soil and objects, reducing the friction of the cast bucket tooth body. When the trapezoidal block penetrates into the soil, the grooves and guide grooves on both sides guide the soil respectively, which plays a role in reducing resistance.

[0024] The utility model provides a casting bucket tooth assembly, embodiment 1, such as Figure 1-Figure 4 As shown, it includes: a cast bucket tooth body 1, guide grooves 5 are respectively provided on the outer surfaces of both sides of the cast bucket tooth body 1, a trapezoidal block 2 is arranged on the front surface of the cast bucket tooth body 1, a plurality of cutting blocks 3 are equidistantly arranged on the top of the cast bucket tooth body 1, and a reinforcing block 4 is respectively provided on the rear surfaces of the plurality of cutting blocks 3, a mounting hole 9 is provided on the rear surface of the cast bucket tooth body 1, the reinforcing block 4 is arranged on the top of the cast bucket tooth body 1, the front surface of the reinforcing block 4 is inclined near the top side, the front surface of the cutting block 3 is inclined, the top of the cutting block 3 is narrower, and the bottom of the cutting block 3 is wider, pin holes 7 are respectively provided on the outer surfaces of both sides of the cast bucket tooth body 1, the two pin holes 7 have the same diameter, and the two pin holes 7 are connected to the mounting hole 9, a retaining spring groove 8 is provided on the inner surface of one side of the mounting hole 9 near one of the pin holes 7, and the retaining spring groove 8 is matched with the pin hole 7, grooves are respectively provided on both sides of the trapezoidal block 2, and the two grooves of the trapezoidal block 2 are respectively connected to the two guide grooves 5.

[0025] The effect achieved by the entire embodiment 1 is that when the cast bucket tooth assembly is used, the damaged or replaced bucket teeth in the excavator bucket are first removed. After the tooth seat is cleaned, a new retaining ring is placed in the retaining ring groove 8. After it is limited, the cast bucket tooth body 1 is docked with the tooth seat in the excavator bucket through the installation hole 9, and the two pin holes 7 are connected to the fixing holes opened on the surface of the tooth seat. The pin is inserted through the other pin hole 7 and the tooth seat in turn. The pin is fixed in the retaining ring through the hammering of the tool to complete the installation. When the bucket is performing shoveling operations, the soil is shoveled through the sharp part of the front side of the trapezoidal block 2. The trapezoidal block 2 and the cast bucket tooth body 1 are connected. The cross-sections are all trapezoidal in shape, narrow in the front and wide in the back. As the trapezoidal blocks 2 penetrate deep into the soil, the grooves and guide grooves 5 on both sides thereof guide the soil respectively, thereby reducing resistance. The front inclined surfaces of the multiple cutting blocks 3 equidistantly fixed on the top of the cast bucket tooth body 1 enable it to shovel into the soil better. The reinforcing blocks 4 fixed on the rear surfaces of the multiple cutting blocks 3 increase the strength. When processing certain special materials or complex excavation environments, such as frozen soil or rock, the sharper top of the cutting block 3 will cut and divert them, cutting and decomposing materials faster, reducing the resistance of the bucket tooth during operation, and improving the shoveling efficiency of the overall cast bucket tooth assembly.

[0026] Embodiment 2, as Figure 1-Figure 4 As shown, guide blocks 6 are respectively arranged on the inner surfaces of the two guide grooves 5 , the cross sections of the two guide blocks 6 are both rhombus-shaped, and multiple outer surfaces of the two guide blocks 6 are respectively inclined to each other.

[0027] The effect achieved by the entire embodiment 2 is that, when in use, by respectively arranging guide blocks 6 on the inner surfaces of the two guide grooves 5, the multiple surfaces of the diamond-shaped guide blocks 6 are inclined to each other, so that when shoveling deep into the soil, the soil and objects in the guide groove 5 can be divided, thereby increasing the guiding speed of the shoveled soil and objects and improving the use effect of the cast bucket tooth assembly.

[0028] Working principle: When the cast bucket tooth assembly is used, first remove the damaged or replaced bucket teeth in the excavator bucket. After cleaning the tooth seat, place the new retaining ring in the retaining ring groove 8. After it is limited, the cast bucket tooth body 1 is docked with the tooth seat in the excavator bucket through the installation hole 9, and the two pin holes 7 are connected to the fixing holes opened on the surface of the tooth seat. The pin is inserted through the other pin hole 7 and the two pin holes 7 and the tooth seat in turn. The pin is fixed in the retaining ring through the hammering of the tool to complete the installation. When the bucket is shoveling and digging, the soil is shoveled through the sharp part of the front side of the trapezoidal block 2. The cross-sections of the trapezoidal block 2 and the cast bucket tooth body 1 are both trapezoidal, narrow in front and wide in the back. As the trapezoidal block 2 goes deep into the soil, the grooves and guide grooves 5 opened on both sides guide the soil respectively to reduce resistance. The front inclined surfaces of the multiple cutting blocks 3 equidistantly fixedly arranged on the top of the cast bucket tooth body 1 will enable it to shovel into the soil better, and the reinforcing blocks 4 fixedly arranged on the rear surfaces of the multiple cutting blocks 3 play a role in increasing the strength. When processing certain special materials or complex excavation environments, such as frozen soil or rocks, the sharper tops of the cutting blocks 3 will cut and divert them, cut and decompose materials faster, reduce the resistance of the bucket teeth during work, and improve the shoveling efficiency of the overall cast bucket tooth assembly. By respectively arranging guide blocks 6 on the inner surfaces of the two guide grooves 5, the multiple surfaces of the diamond-shaped guide blocks 6 are inclined to each other, so that when shoveling deep into the soil, the soil and objects in the guide grooves 5 can be divided, thereby increasing the guiding speed for shoveling soil and objects and improving the use effect of the cast bucket tooth assembly.
