Technical Field

[0001] This utility model relates to the field of excavator technology, and more specifically, to an excavator bucket tooth assembly. Background Technology

[0002] The bucket teeth assembly is a key and vulnerable component of the excavator bucket. It is mainly used to enhance the bucket's digging, crushing, and grabbing capabilities and protect the bucket body from wear. In existing building construction, excavators are often used to dig soil to facilitate foundation construction. During the use of excavators, the bucket teeth often get damaged when they encounter hard rocks. Most existing bucket teeth are welded to the edge of the bucket, making them difficult to disassemble when damaged and requiring re-welding before they can be used again. This is cumbersome and reduces work efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an excavator bucket tooth assembly, which has the advantages of easy installation and disassembly.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 6 As shown, this utility model provides an excavator bucket tooth assembly, including a bucket 1, a connecting plate 2 fixedly installed on the surface of the bucket 1, a snap-fit ​​assembly 3 fixedly installed on the outer side of the connecting plate 2, a support block 4 fixedly installed in front of the snap-fit ​​assembly 3, a fixing plate 5 fixedly installed inside the support block 4, a telescopic rod 6 fixedly installed on the outer side of the fixing plate 5, a spring 7 sleeved on the outer side of the telescopic rod 6, a buckle 8 fixedly installed on the side of the spring 7 away from the fixing plate 5, and bucket teeth 9 snapped onto the outer side of the support block 4. The bucket teeth 9 have an installation groove 10 and a snap hole 11 inside.

[0022] When it is necessary to install the bucket tooth 9, first press the buckle 8 towards the fixing plate 5, causing the spring 7 and the telescopic rod 6 to retract, so that the buckle 8 enters the interior of the support block 4. Then push the bucket tooth 9 inward along the support block 4, so that the bucket tooth 9 fits onto the outside of the support block 4. Then release the buckle 8. When the bucket tooth 9 slides so that the locking hole 11 and the buckle 8 are on the same horizontal line, the spring 7 provides elasticity to pop the buckle 8 outward, so that the buckle 8 and the bucket tooth 9 engage, thus limiting the bucket tooth 9. At this time, the support block 4 is located inside the mounting groove 10 to support the bucket tooth 9, achieving the effect of facilitating installation and operation.

[0023] The bucket 1 is provided with a guard plate 12 and a breaker blade 13 on the outside. The breaker blade 13 is fitted with a bolt 14 inside. The bolt 14 engages with the bucket 1 and fixes the breaker blade 13 to the bucket 1.

[0024] The edge of the breaker blade 13 is plate-shaped. Its main function is to cut the edge of the soil when the bucket 1 is digging, so as to prevent the edges of the bucket 1 from being damaged by the stones.

[0025] Among them, a flat plate 15 is fixedly installed on the outer side of the bucket 1, a connecting component 16 is fixedly installed on the top of the bucket 1, a connecting shaft 17 is fixedly installed inside the connecting component 16, and there are multiple flat plates 15, which cover the rear side of the bucket 1.

[0026] The main function of the multiple leveling plates 15 is to make contact with the ground by pounding the loose soil downwards through the bucket 1 after it has been cleaned, thereby allowing for simple leveling of the ground.

[0027] The bucket 1 has a connecting rod 18 fixedly installed inside, and a groove 19 is provided at the bottom of the connecting rod 18. A slider 20 is slidably connected inside the groove 19. A support plate 21 is fixedly installed at the bottom of the slider 20. A scraper 22 is fixedly installed at the bottom of the support plate 21.

[0028] When an excavator has been working for a long time, it may encounter sticky soil that gets stuck to the inner wall of the bucket 1. If the soil is not cleaned up after the shift, it will stick to the inside of the bucket 1, occupying the internal space of the bucket 1 and making it difficult to clean when the machine continues to work. At this time, the support plate 21 is slidably connected to the slide groove 19 through the slider 20, so that the support plate 21 can move back and forth. Then the scraper 22 will scrape the bottom of the bucket 1, scraping away the soil stuck inside the bucket 1, so as to facilitate cleaning.

[0029] A connecting block 23 is fixedly installed in front of the support plate 21, and a locking rod 24 is snapped into the inside of the connecting block 23. A push-pull rod 25 is fixedly installed in front of the locking rod 24.

[0030] When it is necessary to move the support plate 21 inside the slide groove 19 via the slider 20, the support plate 21 is moved back and forth by pulling the push rod 25, so that there is no need to clean inside the bucket 1 by body, thus increasing the convenience of cleaning.

[0031] There are multiple snap-fit ​​components 3 and multiple support blocks 4. Multiple snap-fit ​​components 3 and multiple support blocks 4 are located in front of bucket 1. There are multiple bucket teeth 9. Multiple bucket teeth 9 are respectively sleeved on the outside of multiple support blocks 4.

[0032] Multiple bucket teeth 9 are supported by multiple internal support blocks 4, enabling the multiple bucket teeth 9 to quickly break up the soil and achieve the effect of convenient digging.

[0033] Working principle and usage process of this utility model:

[0034] First, a fixing plate 5 is fixedly installed inside the support block 4, and a telescopic rod 6 is fixedly installed on the outside of the fixing plate 5. A spring 7 is sleeved on the outside of the telescopic rod 6, and a buckle 8 is fixedly installed on the side of the spring 7 away from the fixing plate 5. A bucket tooth 9 is snapped on the outside of the support block 4. When the bucket tooth 9 needs to be installed, the buckle 8 is first pressed towards the fixing plate 5, causing the spring 7 and the telescopic rod 6 to retract, so that the buckle 8 enters the inside of the support block 4. Then, the bucket tooth 9 is pushed inward along the support block 4, so that the bucket tooth 9 is sleeved on the outside of the support block 4. Then, the buckle 8 is released. When the bucket tooth 9 slides so that the locking hole 11 and the buckle 8 are on the same horizontal line, the spring 7 provides elasticity to pop the buckle 8 outward, so that the buckle 8 snaps on the bucket tooth 9, so that the bucket tooth 9 is limited. At this time, the support block 4 is located inside the mounting groove 10 to support the bucket tooth 9.

[0035] Secondly, the edge of the breaker blade 13 is plate-shaped. Its main function is to cut the edge of the soil when the bucket 1 is digging, so as to prevent the edges of the bucket 1 from being damaged by the stones.

[0036] Finally, when the excavator encounters sticky soil, the sticky soil will stick to the inner wall of the bucket 1. If it is not cleaned after the shift, the soil will stick to the inside of the bucket 1, thus occupying the internal space of the bucket 1 and making it difficult to clean when continuing to work. At this time, the support plate 21 is slidably connected to the slide groove 19 through the slider 20, so that the support plate 21 can move back and forth. At this time, the scraper 22 will scrape the bottom of the bucket 1, so that the soil stuck inside the bucket 1 can be scraped away, achieving the effect of easy cleaning.
