[0010] In some embodiments, the heightening plate is non-removably mounted on the outer edge of the bucket opening.
[0011] In some embodiments, the excavator bucket further includes a fixing rib, which is welded to the heightening plate and the bucket body respectively.
[0012] In some embodiments, the number of fixing ribs is multiple, and the spacing between any two adjacent fixing ribs satisfies:

[0034] As a core component of excavators, the excavator bucket's capacity directly impacts operational efficiency and economic benefits. Traditional excavator buckets are often limited by their structure, making it difficult to simultaneously meet the demands for high capacity and digging power. Current technology typically increases excavator bucket capacity by replacing it with a larger capacity bucket, but this method suffers from high costs and low efficiency. Therefore, how to optimize the excavator bucket's structural design to increase its capacity while maintaining digging power has become a pressing technical problem to be solved in this field.
[0035] Currently, there are solutions that balance increasing excavator bucket capacity and digging ability by improving the structure of the excavator bucket. For example, the bucket capacity can be expanded by installing an outer frame on the bucket opening. However, the connection method and structure of the outer frame are relatively complex, and the installation and disassembly are cumbersome, affecting the excavator's operating efficiency.
[0036] This utility model addresses the technical problems of complex structure and poor stability in existing excavator bucket expansion technologies by providing a new excavator bucket, referring to... Figures 1-4As shown, according to one embodiment of the excavator bucket of this utility model, the excavator bucket includes: a bucket body and a heightening plate. The bucket body includes a bucket bottom plate 6, side plates 5 disposed on both sides of the bucket bottom plate 6, ear plate assemblies 1 and main cutting edge plates 7 and side cutting edge plates 4 respectively connected to both ends of the bucket bottom plate 6. The side cutting edge plates 4 are respectively connected to the side plates 5, main cutting edge plates 7 and ear plate assemblies 1. The side cutting edge plates 4, main cutting edge plates 7 and ear plate assemblies 1 together form a bucket opening. The heightening plate is fixedly connected to the outer edge of the bucket opening.
[0037] In the excavator bucket provided by this utility model, the bucket body includes a bottom plate 6, side plates 5, ear plate assemblies 1, a main cutting edge 7, and side cutting edges 4. The side plates 5 are respectively disposed on both sides of the bottom plate 6, and the ear plate assemblies 1 and the main cutting edge 7 are respectively disposed at both ends of the bottom plate 6. The side cutting edges 4 are installed on the outer side of the side plates 5 and are connected to the ear plate assemblies 1 and the main cutting edge 7 at both ends. The side cutting edges 4, ear plate assemblies 1, and main cutting edge 7 together form a bucket opening. A heightening plate is fixedly connected to the outer edge of the bucket opening, thereby increasing the height of the excavator bucket and expanding its capacity. Moreover, the heightening plate is fixedly connected to the bucket body, that is, the heightening plate is fixedly connected to the outer edge of the bucket opening, making it difficult for the heightening plate to fall off the bucket body and ensuring the stability of the excavator bucket during operation.
[0038] Optionally, the extension plate can be located at any position on the outer edge of the bucket opening. For example, the extension plate can be located on at least one of the side cutting edge 4, the ear plate assembly 1, or the main cutting edge 7.
[0039] According to a preferred embodiment of the excavator bucket of this utility model, see [link to relevant documentation]. Figures 1-3 As shown, the extension plate includes a side extension plate 13 disposed on the side cutting edge plate 4 and a rear extension plate 14 disposed on the ear plate assembly 1. In this way, not only can the bucket capacity of the excavator be increased without affecting the excavator's digging capacity, but the side extension plate 13 disposed on the side cutting edge plate 4 can also reduce the wear of the excavator bucket and extend the service life of the excavator bucket.
[0040] Furthermore, the thickness of the extension plate is not greater than the thickness of the connection between the bucket body and the extension plate. Specifically, the thickness t1 of the side extension plate 13 is not greater than the thickness t of the side cutting edge plate 4, and the thickness of the rear extension plate 14 is not greater than the thickness of the ear plate assembly 1.
[0041] In some implementations, the length of the extension plate on the side closest to the bucket opening is greater than the length of the extension plate on the side furthest from the bucket opening. (Combined with...) Figure 1 and Figure 3 As shown, the upper length of the side extension plate 13 and the rear extension plate 14 is less than the lower length, that is, the side extension plate 13 and the rear extension plate 14 are formed into a trapezoidal shape that is narrower at the top and wider at the bottom, so that the excavator bucket can perform digging operations.
[0042] According to a preferred embodiment of the excavator bucket of this utility model, see [link to relevant documentation]. Figures 1-4 As shown, the side extension plate 13 has an arc-shaped outer contour that is concave towards the ear plate assembly 1 at one end near the main cutting edge plate 7, which is beneficial to improving the digging capacity of the excavator bucket.
[0043] Furthermore, the side of the side extension plate 13 has a chamfer, which is organically combined with the aforementioned arc-shaped outer contour. This combination not only optimizes the flow path of material entering the excavator bucket, allowing material to enter smoothly and reducing material accumulation, but also significantly reduces the probability of material jamming during excavation, thereby improving the excavator's digging efficiency. Therefore, through the synergistic cooperation of the arc-shaped outer contour and the chamfer, the side extension plate 13 achieves optimization in functionality, durability, and operational efficiency, enhancing the overall performance and usability of the excavator bucket.
[0044] Optionally, the position and size of the extension plates, such as the side extension plate 13 and the rear extension plate 14, can be flexibly adjusted according to actual conditions. For example, in one embodiment, see [link to embodiment]. Figure 1 , Figure 3 and Figure 4 As shown, the side cutting edge 4 is provided with a side heightening plate 13 and a side guard tooth 8, the side guard tooth 8 being used to protect the side cutting edge 4. Alternatively, in another embodiment, see... Figure 2 As shown, the side guard teeth 8 on the side blade 4 can be removed, and the length of the side heightening plate 13 can be extended to further increase the bucket capacity of the excavator bucket.
[0045] Furthermore, the height of the extension plates can be adjusted according to actual operating conditions. For example, in operating environments with high material density or large volume, a lower extension plate can be installed to prevent multiple materials from getting stuck in the openings between the extension plates due to excessive weight or volume, thus reducing the effective loading space of the excavator bucket and affecting the actual loading capacity and operating efficiency. Conversely, in operating environments with low material density or small volume, a higher extension plate can be installed to improve the loading capacity and operating efficiency of the excavator bucket. Therefore, by adjusting the position and size of the extension plates, the versatility and adaptability of the bucket are enhanced, enabling it to efficiently handle various complex operating needs while balancing flexibility and practicality.
[0046] In some embodiments, the extension plate is detachably mounted on the outer edge of the bucket opening, making it easy to install and remove, thereby improving the working efficiency of the excavator. Specifically, the side extension plate 13 is detachably connected to the side cutting edge plate 4, and the rear extension plate 14 is detachably connected to the ear plate assembly 1. In the excavator bucket of this utility model, the detachable connection methods include, but are not limited to, bolt connections, pin connections, etc., for example, see [reference needed]. Figure 2 As shown, the side extension plate 13 and the side blade plate 4 are respectively provided with threaded holes, and the side extension plate 13 and the side blade plate 4 are connected by bolts.
[0047] Alternatively, in other embodiments, the extension plate is non-detachably disposed on the outer edge of the bucket opening. Specifically, the side extension plate 13 is non-detachably connected to the side cutting edge plate 4, and the rear extension plate 14 is non-detachably connected to the ear plate assembly 1. In the excavator bucket of this utility model, the non-detachable connection methods include, but are not limited to, welding connection, riveting connection, and bonding. For example, the extension plate is welded to the bucket body.
[0048] According to one embodiment of the excavator bucket of this utility model, the excavator bucket further includes a fixing rib 15, which is welded to the extension plate and the bucket body respectively. (Refer to...) Figure 1 , Figure 3 and Figure 4 As shown, the fixing rib 15 is welded to the side extension plate 13 and the side blade plate 4 respectively, and the fixing rib 15 is welded to the rear extension plate 14 and the ear plate assembly 1 respectively.
[0049] Optionally, the installation position, size, and shape of the fixing rib 15 can be adapted to the actual operating conditions. For example, refer to... Figure 3 and Figure 4 As shown, according to a preferred embodiment of the excavator bucket of this utility model, the number of fixing ribs 15 is multiple, and the spacing between any two adjacent fixing ribs 15 satisfies:
[0050] d = L / (n+1);
[0051] Where d is the spacing between any two adjacent fixed reinforcing bars 15;
[0052] L is the length of the raised plate;
[0053] n represents the number of fixed reinforcing bars 15.
[0054] When the spacing d between any two adjacent fixed ribs 15, the length L of the extension plate, and the number n of the fixed ribs 15 satisfy the above relationship, it can be ensured that the fixed ribs 15 are evenly distributed on the extension plate. Moreover, by optimizing the arrangement density of the fixed ribs 15, the local strength between the bucket body and the extension plate can be enhanced, while avoiding local stress concentration and improving the stability and durability of the overall structure. In addition, a reasonable design of the spacing d can also optimize the amount of material used, further optimize costs, and achieve the dual goals of high efficiency and economy.
[0055] In some embodiments, the thickness of the fixing rib 15 does not exceed the thickness of the extension plate. Specifically, the thickness t1 of the side extension plate 13 is not greater than the thickness t of the side cutting edge plate 4, and the thickness t2 of the fixing rib 15 connecting the side extension plate 13 and the side cutting edge plate 4 is not greater than the thickness t1 of the side extension plate 13. The thickness of the rear extension plate 14 is not greater than the thickness of the ear plate assembly 1, and the thickness of the fixing rib 15 connecting the rear extension plate 14 and the ear plate assembly 1 is not greater than the thickness of the rear extension plate 14. The thickness matching design between the fixing rib 15, the extension plate, and the bucket body ensures the stability and reliability of the overall structure of the excavator bucket.
[0056] Optionally, the shape of the fixing rib 15 can be arbitrary, as long as it can connect the extension plate to the bucket body.
[0057] The shape of the fixing rib 15 can be adjusted according to actual connection requirements. In some embodiments, when the height and length of the extension plate are small, excessive fixing is not required between the extension plate and the bucket body. The fixing rib 15 includes a first fixing rib 15-1, combined with... Figure 1 , Figure 3 and Figure 4 As shown, the first fixing rib 15-1 is rectangular in shape, and along the length of the cuboid, the first fixing rib 15-1 is welded to the extension plate and the bucket body respectively. Alternatively, in some other embodiments, when the height and length of the extension plate are large, the fixing rib 15 includes at least one of the second fixing rib 15-2, the third fixing rib 15-3, and the fourth fixing rib 15-4, combined with... Figure 1 , Figure 3 and Figure 4As shown, the second fixing rib 15-2 is basically cuboid in shape, with beveled edges at both ends; the third fixing rib 15-3 is basically cuboid in shape, with curved edges at both ends; and the fourth fixing rib 15-4 is basically cuboid in shape, with partially curved edges at both ends. Furthermore, the ends of the fixing rib 15 can be a combination of the above shapes, for example, one end of the fixing rib 15 has a beveled edge, and the other end has a beveled curved edge. By forming beveled or curved edges at both ends of the fixing rib 15, the strength of the welded connection between the fixing rib 15 and the extension plate and the bucket body is improved, enhancing the stability of the fixed connection between the extension plate and the bucket body.
[0058] In this invention, there are various welding methods for the fixing rib 15 to the extension plate and the bucket body. For example, in some embodiments, the fixing rib 15 is configured such that its non-ends are welded to the extension plate and the bucket body respectively, while its ends are not welded to the extension plate and the bucket body. This avoids stress concentration at the ends of the fixing rib 15, improving overall stability and fatigue resistance. Alternatively, in other embodiments, the fixing rib 15 is welded to the extension plate and the bucket body respectively, forming a circumferential weld. The circumferential weld ensures a smooth weld transition and uniform stress distribution, while spot welding is used at key stress points to strengthen the structural strength of local areas.
[0059] Furthermore, the fixing rib 15 has a welded enlargement structure, which is used to increase the welding area between the fixing rib 15 and the extension plate and the bucket body. In conjunction with the aforementioned embodiments, the welded enlargement structure may be formed as beveled or arc-shaped edges at both ends of the fixing rib 15. Of course, the welded enlargement structure may also be formed at other locations of the fixing rib 15.
[0060] In another embodiment of the excavator bucket of this utility model, see [link to relevant documentation]. Figure 1 As shown, the excavator bucket also includes a first reinforcing rib 2 and a second reinforcing rib 3 connected to the side cutting edge 4 and the ear plate assembly 1 respectively, side guard teeth 8 disposed on the side cutting edge 4, tooth seats 9 disposed on the main cutting edge 7, guard lips 11 disposed between the tooth seats 9, bucket teeth disposed on the tooth seats 9, wear-resistant strips 12 disposed on the bottom and sides of the side plate 5 respectively, and a reinforcing plate 16 disposed on the top of the side plate 5. The above-described structure of the excavator bucket is well known to those skilled in the art and is not part of the core improvement of this utility model, therefore it will not be described in detail here.
[0061] In addition, this utility model also provides an excavator, which includes the excavator bucket described above.
[0062] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings; however, this utility model is not limited thereto. Within the scope of the technical concept of this utility model, various simple modifications can be made to the technical solution of this utility model, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed by this utility model and all fall within the protection scope of this utility model.
