[0002] Excavator bucket teeth are important components of the excavator, similar to human teeth, and are also wearing parts. They are combined bucket teeth consisting of a tooth seat and a tooth tip, which are connected by a pin shaft. Since the part of the bucket tooth that fails due to wear is the tooth tip, you only need to replace the tooth tip.

[0003] A high-stability connection structure between a bucket tooth and a bucket tooth seat is disclosed in the Chinese utility model patent application disclosure CN219157828U. Although a mounting groove is provided in the bucket tooth seat, a clamping block is provided in the mounting groove, a connecting block is provided on the bucket tooth tip, and a clamping groove is provided on the surface of the connecting block, when in use, the bucket tooth tip can be clamped into the bucket tooth seat through the connecting block, and then the clamping block is moved by a threaded rod, and the clamping block is clamped into the clamping groove, so that the bucket tooth tip is fixedly installed in the bucket tooth seat, and the mounting groove is adapted to the connecting block, and the clamping block is adapted to the clamping groove, so that the connecting block does not shake in the bucket tooth seat, which greatly improves the stability of the connection between the bucket tooth tip and the bucket tooth seat, but the existing device lacks a device for fixing the bucket tooth and the bucket tooth tip to improve stability, which is very likely to cause the problem of bucket teeth or bucket tooth tips breaking after multiple excavation uses, and also lacks a device for increasing the welding area between the bucket tooth and the bucket, which is very likely to cause the problem of fracture of the connection between the bucket tooth and the bucket in the later stage due to the welding surface being too small. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0025] As a preferred implementation in this embodiment, Figure 2 and Figure 3As shown, a connecting seat 2 is inserted into one side of the connecting plate 1, and a tightening bolt 3 is penetrated through the internal thread of the connecting seat 2. A bucket tooth 4 is sleeved on the surface of the tightening bolt 3, and a fixing plate 5 is inserted into the lower surface of the bucket tooth 4. A positioning rod 6 is inserted into the interior of the bucket tooth 4, and a reset spring 7 is sleeved on the surface of the positioning rod 6. A push rod 8 is inserted into one end of the reset spring 7, and a support block 9 is inserted into one end of the push rod 8. A bucket tooth tip 10 is slidably connected to one side of the bucket tooth 4, and a pull rod 11 is inserted into one side of the bucket tooth tip 10. There are two connecting seats 2, each of which is located on one side of the connecting plate 1. A thread is provided inside the connecting seat 2 to match the tightening bolt 3. The upper and lower parts of the inner wall of the bucket tooth 4 are provided with sliding grooves. The left side of the fixing plate 5 can be engaged with the lower part of the connecting plate 1. The bucket tooth 4 is connected in a row, and a parallel slide groove corresponding to one side of the bucket tooth 4 is provided inside the bucket tooth tip 10, so that the support block 9 can slide from the inside of the bucket tooth 4 into the inside of the bucket tooth tip 10, and the upper surface of the support block 9 is provided with a parallel slide block corresponding to the parallel slide groove. During use, it can be welded with the bucket through the connecting plate 1, so that the bucket tooth 4 and the bucket can be connected more stably, and the problem of falling off after multiple uses due to the small connection area between the bucket tooth 4 and the bucket is avoided, and the effect of greatly increasing the welding area between the bucket tooth 4 and the bucket is greatly increased. The bucket tooth 4 can be manually fixed to the connecting plate 1 by tightening the bolt 3, so that the bucket tooth 4 can be manually and stably fixed to one side of the connecting plate 1, and the bucket tooth 4 can be easily replaced, avoiding The problem that the connection between the bucket tooth 4 and the connecting plate 1 is unstable, resulting in looseness, and the bucket tooth 4 is damaged and cannot be replaced after being used many times, the bucket tooth 4 can be fixed to the connecting plate 1 through the fixing plate 5, so that the bucket tooth 4 can be stably fixed to one side of the connecting plate 1 again, avoiding the problem that the bucket tooth 4 cannot be stable after being used many times due to only one fixing method, and the support block 9 can be moved inside the bucket tooth 4 and the bucket tooth tip 10 through the reset spring 7 and the push rod 8, so that when the bucket tooth tip 10 is pressed down, the push rod 8 drives the support block 9 to enter the bucket tooth tip 10 to support and increase the hardness of the bucket tooth tip 10, avoiding the bucket tooth tip 10 being repeatedly excavated during use. The problem of the tooth tip 10 being broken in the middle part can be solved by limiting the reset spring 7 through the positioning 6, so that the reset spring 7 can be kept parallel at the same position when pressed and reset, avoiding the problem of the reset spring 7 being offset after pressing the reset spring 7 for many times. The tooth tip 10 can be pressed into the bucket tooth 4 through the reset spring 7 during excavation, so that the tooth tip 10 can be temporarily buffered during excavation and the support block 9 can enter the bucket tooth tip 10 to support it, avoiding the problem of the support block 9 being unable to enter the bucket tooth tip 10 and causing inconvenience in supporting it. It is worth noting that the tooth tip 10 can be pressed and reset at one end of the reset spring 7 during excavation.

[0026] like Figure 4As shown, in this embodiment, the upper surface of the lower support plate 12 is plugged with a shaft seat 13, and the shaft seat 13 is rotatably connected to the interior of the shaft seat 13 with a rotating shaft 14. Both ends of the rotating shaft 14 are provided with protruding blocks that can be stuck in the shaft seat 13. The surface of the rotating shaft 14 is sleeved with an upper support plate 15, and the upper surface of the upper support plate 15 is provided with a sliding block that can correspond to the sliding groove provided on the inner wall of the bucket tooth 4. During use, the lower support plate 12 and the upper support plate 15 can be folded inside the bucket tooth 4 through the pull rod 11 and the rotating shaft 14, so that after the bucket tooth tip 10 is pressed into the bucket tooth 4, the bucket tooth tip 10 drives the pull rod 11 to push the lower support plate 12 and the upper support plate 15 into an upright state to press the bucket tooth 4. The supporting and fixing effect in the middle position avoids the problem of bucket teeth 4 breaking due to excessive force during excavation, and at the same time increases the hardness of the overall equipment during excavation, avoiding the problem of bucket teeth 4 breaking when multiple excavation uses and when encountering harder objects that require forceful excavation. It is worth noting that when the bucket tooth tip 10 slides inside the bucket tooth 4, it will drive the pull rod 11 to move horizontally, and one end of the pull rod 11 is inserted into the plug hole opened on one side of the upper support plate 15. When the bucket tooth tip 10 enters the bucket tooth 4, the lower support plate 12 and the upper support plate 15 are pushed into an upright state. After the bucket tooth 4 is reset, the pull rod 11 drives the lower support plate 12 and the upper support plate 15 to become semi-folded.

[0027] How this utility works:

[0028] During use, the bucket can be welded to the connecting plate 1, so that the bucket teeth 4 and the bucket can be connected more stably, avoiding the problem of falling off after repeated use due to the small connection area between the bucket teeth 4 and the bucket, and greatly increasing the welding area between the bucket teeth 4 and the bucket. The bucket teeth 4 and the connecting plate 1 can be manually fixed by tightening the bolts 3, so that the bucket teeth 4 can be stably fixed to one side of the connecting plate 1 manually and the bucket teeth 4 can be easily replaced, avoiding the loosening caused by the unstable connection between the bucket teeth 4 and the connecting plate 1 and the damage of the bucket teeth 4 after repeated use. To solve the problem of replacing the bucket tooth 4, the fixing plate 5 can be used to fix the bucket tooth 4 and the connecting plate 1, so that the bucket tooth 4 can be stably fixed to one side of the connecting plate 1 again, avoiding the problem that the bucket tooth 4 cannot be stable after multiple uses due to only one fixing method. The support block 9 can be moved inside the bucket tooth 4 and the bucket tooth tip 10 through the reset spring 7 and the push rod 8, so that when the bucket tooth tip 10 is pressed down, the push rod 8 drives the support block 9 to enter the bucket tooth tip 10 to support the bucket tooth tip 10 up and down to increase the hardness of the bucket tooth tip 10, avoiding the bucket tooth tip 10 being in use. In order to solve the problem that the middle part of the bucket tooth tip 10 is broken due to multiple excavations, the positioning 6 can be used to limit the reset spring 7, so that the reset spring 7 can be kept parallel at the same position when pressed and reset, avoiding the problem that the reset spring 7 is offset after multiple pressing of the reset spring 7. The bucket tooth tip 10 can be pressed into the bucket tooth 4 through the reset spring 7 during excavation, so that the bucket tooth tip 10 can be temporarily buffered during excavation and the support block 9 can enter the bucket tooth tip 10 to support it, avoiding the problem that the support block 9 cannot enter the bucket tooth tip 10. 0, which makes it inconvenient to support it. Through the pull rod 11 and the rotating shaft 14, the lower support plate 12 and the upper support plate 15 can be folded inside the bucket tooth 4, so that after the bucket tooth tip 10 is pressed into the bucket tooth 4, the bucket tooth tip 10 drives the pull rod 11 to push the lower support plate 12 and the upper support plate 15 into a vertical state to support and fix the middle position inside the bucket tooth 4, avoiding the problem of the bucket tooth 4 breaking due to excessive force during excavation, and at the same time increasing the hardness of the overall equipment during excavation, avoiding the problem of the bucket tooth 4 breaking when it is used for multiple excavations or when it encounters a hard object and needs to be excavated with force.
