Description

Technical Field

[0001] The utility model relates to the technical field of excavator bucket teeth, in particular to a bucket tooth which is convenient for maintenance and replacement. Background Art

[0002] Bucket teeth are an important part of the front end of the excavator bucket. Similar to human teeth, they can easily dig out the required materials from the earth and stone. Their sharp front edges can effectively cut soft strata, gravel, tree roots, etc., making excavation faster and more efficient. In addition, bucket teeth can also be used for digging, digging earth and stone out from underground for subsequent cleaning and loading work.

[0003] A quick-change excavator bucket tooth is disclosed in the Chinese utility model patent application publication specification CN218346316U. The invention can quickly complete the installation and disassembly of multiple bucket tooth blocks on the excavator bucket, which is convenient for the maintenance and replacement of the bucket tooth blocks. The installation and disassembly efficiency is high, and the spacing between the corresponding bucket tooth blocks can be flexibly adjusted, which can increase the applicable scope of the excavator bucket. Although it is convenient to install and disassemble the bucket tooth blocks and adjust the spacing between the bucket tooth blocks, in actual use, the existing bucket tooth blocks are mostly one-piece structures, and when the bucket tooth blocks are damaged, generally only a small area of ​​the bucket tooth tip is damaged, and the rear connection structure of the bucket tooth block can still be used normally. At this time, the entire bucket tooth block is directly replaced after replacement, and the part of the structure behind the front end of the bucket tooth block that is not damaged is directly discarded, which not only causes waste, but also increases the cost of accessories. In addition, the tip of the bucket tooth block currently used cannot be adjusted in angle. When excavating relatively wet soil, it is not easy to generate a force under the excavated soil. Mud often falls everywhere, affecting the loading efficiency. Therefore, it is necessary to provide a bucket tooth that is easy to maintain and replace to solve the above-mentioned problems.

Then, by rotating the threaded push rod, it can be moved forward along the groove opened in the middle of the reinforcement plate. Since the shaft rod at the front end of the threaded push rod is sleeved and installed in the adjustment groove, the lower structure of the inner gear block is pushed forward while the displacement occurs, so that the inner gear block is tilted, thereby driving the inner gear rod below to adjust the angle. After adjusting to a suitable angle, an upward force is generated during wet earth excavation, thereby reducing the falling of earth and improving the loading efficiency.

If the inner tooth rod is damaged during work, it can be directly disassembled and replaced, and the inner tooth block can continue to be used, thereby reducing the cost of accessories. In addition, an outer tooth block is installed at the outer end of the inner tooth rod. When digging hard objects and stones, the inner tooth rod is protected and the probability of damage is reduced. The design of the rubber inner pad on the inner side of the outer tooth block can also reduce the friction between the inner tooth rod and the outer tooth block, thereby increasing the service life of the inner tooth rod.

[0019] 3. In the utility model, the bucket teeth are decomposed into reinforcement blocks, clamping components, inner tooth components and outer tooth components, which are spliced ​​and installed with each other, so that subsequent maintenance and replacement are more time-saving and labor-saving.

If the inner tooth rod 502 is damaged during operation, it can be directly disassembled and replaced, and the inner tooth block 501 can continue to be used, thereby reducing the cost expenditure of accessories. In addition, an outer tooth block 601 is installed at the outer end of the inner tooth rod 502. When digging into hard objects and stones, the inner tooth rod 502 is protected and the probability of damage is reduced. Secondly, through the design of the rubber inner pad 603, the friction between the inner tooth rod 502 and the outer tooth block 601 can also be reduced, thereby increasing the service life of the inner tooth rod 502.

Since the shaft rod 408 at the front end of the threaded push rod 406 is sleeved and installed in the adjusting slot 504, the lower structure of the inner tooth block 501 is pushed forward while moving, so that the inner tooth block 501 is tilted, thereby driving the inner tooth rod 502 below to adjust the angle. After adjusting to the appropriate angle, an upward force is generated during wet earth excavation, thereby reducing the falling of earth and improving the loading efficiency. Subsequently, the connecting rod 406 is provided The joint 503 allows the inner tooth block 501 and the inner tooth rod 502 to be separated into two parts. If the inner tooth rod 502 is damaged during work, it can be directly disassembled and replaced, and the inner tooth block 501 can continue to be used, thereby reducing the cost of accessories. In addition, an outer tooth block 601 is installed at the outer end of the inner tooth rod 502. When digging hard objects and stones, the inner tooth rod 502 is protected and the probability of damage is reduced. The design of the rubber inner pad 603 on the inside of the outer tooth block 601 can also reduce the friction between the inner tooth rod 502 and the outer tooth block 601, thereby increasing the service life of the inner tooth rod 502. Secondly, by decomposing the bucket tooth into the reinforcement block 3, the clamping assembly 4, the inner tooth assembly 5 and the outer tooth assembly 6, which are directly spliced ​​and installed, subsequent maintenance and replacement are also more time-saving and labor-saving.
