Description

Technical Field

[0001] This utility model relates to the field of bucket teeth technology, specifically to a novel bucket tooth. Background Technology

[0002] Bucket teeth are an important component of excavators, similar to human teeth. They are also wear parts and consist of a tooth base and tooth tips connected by a pin.

[0003] Currently, the tooth base and tooth tip are only connected by a pin. However, bucket teeth require a lot of force and sometimes need to shake during use. This makes it easy for the pin to shake and fall off after connection, causing the tooth base and tooth tip to separate. This can lead to the loss of the bucket tooth tip and affect the normal use of the excavator. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel type of bucket tooth.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A new type of bucket tooth, comprising:

[0007] Tooth tips and tooth bases;

[0008] The mounting mechanism includes a mounting groove at the lower end of the tooth base. Multiple locking strips are symmetrically fixedly connected to the upper sides of both sides of the tooth tip. Multiple slots corresponding to the multiple locking strips are opened on the inner wall of the mounting groove. A groove is opened on the side wall of the tooth base above the mounting groove. The upper ends of the multiple locking strips penetrate the top of the mounting groove and fit against the top of the groove.

[0009] Preferably, the installation mechanism further includes a sealing plate, the sidewall of which fits against the inner wall of the groove, and the sidewall of the sealing plate is threaded with a plurality of threaded rods, the sidewalls of which are threaded to the sidewalls of the retaining strip and the tooth seat, and the sidewalls of the threaded rods away from the sealing plate are threaded with nuts, the sidewalls of which are tightly fitted against the sidewalls of the tooth seat.

[0010] Preferably, the inner wall of the tooth base is symmetrically provided with sliding grooves, and the inner walls of the two sliding grooves are slidably connected with U-shaped plates. The side walls of the U-shaped plates are elastically connected to the inner walls of the sliding grooves by multiple springs. The side wall of the tooth tip is provided with two limiting grooves that correspond one-to-one with the two U-shaped plates. The lower side wall of the U-shaped plate penetrates the inner wall of the mounting groove and is directly opposite the inner wall of its corresponding limiting groove.

[0011] Preferably, two wedge-shaped rods are fixedly connected to the side wall of the sealing plate near the groove. The upper side walls of the two U-shaped plates penetrate the inner wall of the groove, and wedge-shaped blocks are fixedly connected to the adjacent side walls of the two U-shaped plates in the groove. The side walls of the wedge-shaped rods are in contact with the side walls of the wedge-shaped blocks.

[0012] Preferably, multiple protruding teeth are fixedly connected to the lower sidewalls on both sides of the tooth tip, and a connecting groove is provided at the upper end of the tooth base.

[0013] This utility model has the following beneficial effects:

[0014] 1. Set up the installation mechanism by inserting multiple retaining strips on the tooth tip into multiple retaining slots. Then, align the upper ends of the multiple retaining strips with the top of the grooves. Next, place the sealing plate in the grooves and align it with the side walls of the multiple retaining strips. Finally, thread multiple threaded rods are threaded to the side walls of the sealing plate, the side walls of the multiple retaining strips, and the side walls of the tooth seat, and then connected to the nuts until the side wall of the nut is tightly aligned with the side wall of the tooth seat. This completes the fixing of the multiple retaining strips and the installation between the tooth tip and the tooth seat. This avoids the problem of the existing technology that only uses a pin to connect the tooth, which makes the pin easy to shake and fall off after connection, leading to the separation of the tooth seat and the tooth tip, and further causing the loss of the bucket tooth tip, affecting the normal use of the excavator.

[0015] 2. Set up U-shaped plates and limiting grooves. After the sealing plate is placed in the groove and abuts against the side walls of multiple clips, the two wedge rods on the sealing plate can squeeze the two wedge blocks, causing the two wedge blocks to drive the two U-shaped plates closer to each other. This allows the lower side walls of the two U-shaped plates to be inserted into the two limiting grooves respectively, limiting the position of the tooth tip and preventing the tooth tip from moving. Furthermore, after the positions of the subsequent multiple threaded rods are fixed, the position of the sealing plate remains unchanged, increasing the installation stability between the tooth tip and the tooth seat.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A new type of bucket tooth includes a tooth tip 1 and a tooth base 3. Multiple protruding teeth 2 are fixedly connected to the lower side walls on both sides of the tooth tip 1. After the tooth tip 1 moves down and applies pressure to the object, the multiple protruding teeth 2 can further apply pressure to the object and crack it to a greater extent. A connecting groove 4 is provided on the upper end of the tooth base 3 for connecting with an external excavator. The connection method is existing technology and will not be described in detail here.

[0025] The mounting mechanism includes a mounting groove 5 at the lower end of the tooth base 3. Multiple locking strips 6 are symmetrically fixedly connected to the upper sides of both sides of the tooth tip 1. Multiple slots 7 corresponding to the multiple locking strips 6 are opened on the inner wall of the mounting groove 5. A groove 8 is opened on the side wall of the tooth base 3 above the mounting groove 5. The upper ends of the multiple locking strips 6 all penetrate the top of the mounting groove 5, and the upper ends of the multiple locking strips 6 are all in contact with the top of the groove 8.

[0026] The mounting mechanism also includes a sealing plate 9, the side wall of the sealing plate 9 is in contact with the inner wall of the groove 8, and multiple threaded rods 10 are threadedly connected to the side wall of the sealing plate 9. The side walls of the multiple threaded rods 10 are threadedly connected to the side walls of the clip 6 and the tooth seat 3. Nuts 11 are threadedly connected to the side walls of the threaded rods 10 away from the sealing plate 9, and the side walls of the nuts 11 are tightly in contact with the side walls of the tooth seat 3.

[0027] During the installation of the tooth tip 1 and tooth base 3, multiple retaining strips 6 on the tooth tip 1 are inserted into multiple retaining slots 7 respectively. Then, the upper ends of the multiple retaining strips 6 are aligned with the top of the groove 8. Finally, the sealing plate 9 is placed in the groove 8 and aligned with the side walls of the multiple retaining strips 6 (e.g., ...). Figure 4 and Figure 5As shown in the diagram, the multiple threaded rods 10 are then threaded to the side walls of the sealing plate 9, the multiple retaining strips 6, and the tooth seat 3, respectively, and then connected to the nuts 11 until the side wall of the nut 11 is tightly fitted to the side wall of the tooth seat 3. This completes the fixing of the multiple retaining strips 6 and the installation between the tooth tip 1 and the tooth seat 3. This avoids the situation in the prior art where the connection is only made by a pin, which makes it easy for the pin to shake and fall off after connection, thus causing the tooth seat 3 and the tooth tip 1 to separate, and further causing the bucket tooth tip 1 to be lost, affecting the normal use of the excavator.

[0028] The inner wall of the tooth base 3 is symmetrically provided with sliding grooves 12. A U-shaped plate 13 is slidably connected to the inner wall of each of the two sliding grooves 12. The sidewall of the U-shaped plate 13 is elastically connected to the inner wall of the sliding groove 12 by multiple springs 14. The sidewall of the tooth tip 1 is provided with two limiting grooves 15 corresponding one-to-one with the two U-shaped plates 13. The lower sidewall of the U-shaped plate 13 penetrates the inner wall of the mounting groove 5 and is directly opposite the inner wall of its corresponding limiting groove 15 (e.g., ...). Figure 2 and Figure 6 (As shown).

[0029] Two wedge rods 16 are fixedly connected to the side wall of the sealing plate 9 near the groove 8. The upper side walls of the two U-shaped plates 13 penetrate the inner wall of the groove 8, and wedge blocks 17 are fixedly connected to the adjacent side walls of the two U-shaped plates 13 in the groove 8. The side walls of the wedge rods 16 and the side walls of the wedge blocks 17 are in contact with each other.

[0030] After the upper ends of multiple retaining strips 6 are all in contact with the top of the groove 8, the lower sidewalls of the two U-shaped plates 13 are directly opposite the two limiting grooves 15. Then, after the sealing plate 9 is placed in the groove 8 and in contact with the sidewalls of the multiple retaining strips 6, the two wedge-shaped rods 16 on the sealing plate 9 can press against the two wedge blocks 17 (e.g., Figure 6 As shown), the two wedge blocks 17 cause the two U-shaped plates 13 to move closer to each other, so that the lower sidewalls of the two U-shaped plates 13 are respectively inserted into the two limiting grooves 15, limiting the position of the tooth tip 1, preventing the tooth tip 1 from moving, and after the positions of the subsequent multiple threaded rods 10 are fixed, the position of the sealing plate 9 remains unchanged, increasing the installation stability between the tooth tip 1 and the tooth seat 3.

[0031] When installing between the tooth tip 1 and the tooth base 3, first insert the multiple retaining strips 6 on the tooth tip 1 into the multiple retaining slots 7 respectively. Then, align the upper ends of the multiple retaining strips 6 with the top of the groove 8. Next, place the sealing plate 9 in the groove 8 and align it with the side walls of the multiple retaining strips 6 (e.g., Figure 4 and Figure 5 (As shown), finally, the multiple threaded rods 10 are threaded to the side wall of the sealing plate 9, the side wall of the multiple clips 6 and the side wall of the tooth seat 3 respectively, and then connected to the nut 11 until the side wall of the nut 11 is tightly fitted with the side wall of the tooth seat 3, thus completing the fixation of the multiple clips 6 and the installation between the tooth tip 1 and the tooth seat 3.

[0032] And after the upper ends of multiple retaining strips 6 are all in contact with the top of the groove 8, the lower sidewalls of the two U-shaped plates 13 are directly opposite the two limiting grooves 15. Then, after the sealing plate 9 is placed in the groove 8 and in contact with the sidewalls of the multiple retaining strips 6, the two wedge rods 16 on the sealing plate 9 can press against the two wedge blocks 17 (e.g., Figure 6 As shown), the two wedge blocks 17 drive the two U-shaped plates 13 to move closer to each other, so that the lower sidewalls of the two U-shaped plates 13 are respectively inserted into the two limiting grooves 15, limiting the position of the tooth tip 1, preventing the tooth tip 1 from moving, and after the positions of the subsequent multiple threaded rods 10 are fixed, the position of the sealing plate 9 does not move, increasing the installation stability between the tooth tip 1 and the tooth seat 3.

[0033] Subsequently, the staff can connect to an external excavator through the connecting slot 4. After the tooth tip 1 moves down to apply pressure to the object during subsequent use, the multiple protruding teeth 2 can further apply pressure to the object, causing it to crack to a greater extent.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
