[0002] With the continuous development of construction, mining, and infrastructure, excavators are playing an increasingly important role in engineering construction. As one of the core components of excavation operations, the performance of the excavator bucket and its bucket teeth directly affects excavation efficiency and equipment life. Traditional excavator bucket design mainly focuses on its structural strength and wear resistance. However, in actual use, the fixing method of the bucket teeth often becomes a key factor affecting ease of use and maintenance costs.

[0003] In the prior art, during the use of traditional excavator buckets, the bucket teeth mostly adopt a fixed design, that is, the bucket teeth are connected to the bucket by pins or bolts. Although this design can meet the needs of excavation operations to a certain extent, when the bucket teeth need to be replaced due to long-term wear or accidental damage, the fixed design often requires disassembly of the entire bucket, and the bucket teeth that need to be replaced need to be disassembled one by one. This process is cumbersome and time-consuming, which not only increases maintenance costs, but also affects the progress of the project, thereby resulting in poor use of the excavator bucket.

[0004] Therefore, an excavator bucket and an excavator are needed to solve the problem that when replacing the bucket teeth of the existing excavator bucket, the bucket teeth that need to be replaced need to be disassembled one by one, which is not only time-consuming and labor-intensive, but also increases maintenance costs, resulting in poor use of the excavator bucket.

[0025] Example 1: Please refer to Figures 1-8 The utility model provides a technical solution: an excavator bucket, including an excavator bucket body 1 and bucket teeth 2, a fixed block 4 is installed on both sides of the bottom of the excavator bucket body 1, a plug-in slot 8 is opened on the adjacent side of the fixed block 4 on the left and right sides, a plug-in block 16 is inserted into the inner wall of the plug-in slot 8, a support plate 3 is installed between the plug-in blocks 16 on the left and right sides, a plurality of mounting slots 12 are opened on the top of the support plate 3, a plurality of slots 5 are opened on the bottom of the excavator bucket body 1, and the bucket teeth 2 are installed on both sides. It is equipped with a connecting plate 13; the bucket tooth 2 is inserted into the inner wall of the mounting groove 12, and the top of the bucket tooth 2 is inserted into the inner wall of the slot 5, so that the bucket tooth 2 fits with the bottom of the excavator hopper body 1, thereby improving the stability of the bucket tooth 2 after insertion, and the connecting plate 13 is inserted into the inner wall of the mounting groove 12, and the top of the support plate 3 fits with the bottom of the excavator hopper body 1, so that the support plate 3 fits tightly with the bottom of the excavator hopper body 1, thereby improving its stability after insertion and facilitating subsequent disassembly and use.

[0026] First, pull the support plate 3 forward, driving the plug-in blocks 16 on both sides to slide forward along the inner wall of the plug-in groove 8, and at the same time driving multiple bucket teeth 2 to gradually detach from the bottom of the excavator bucket body 1. At this time, the bucket tooth 2 to be replaced can be removed, and the connecting plates 13 on both sides can be driven out of the mounting groove 12, so that the operator does not need to disassemble and replace multiple bucket teeth 2 one by one, so as to reduce the complexity of disassembly and thereby improve the use effect of the excavator bucket body 1. After the replacement is completed, the replaced bucket tooth 2 is inserted into the inner wall of the mounting groove 12, and at the same time, the connecting plates 13 on both sides are driven to be inserted into the inner wall of the mounting groove 12. At this time, the support plate 3 can be inserted forward into the bottom of the excavator bucket body 1, and the plug-in blocks 16 on both sides can be driven to be inserted into the inner wall of the plug-in groove 8, which is convenient for the operator to use and convenient for subsequent disassembly and assembly.

[0027] The second embodiment: On the basis of the first embodiment, in order to achieve the fixation between the support plate 3 and the fixing block 4, a through groove 11 is provided at the lower part of the fixing block 4, and a fixing bolt 9 is inserted into the inner wall of the through groove 11. A gasket 10 is sleeved on the outer side of the fixing bolt 9, and a threaded groove 15 is provided on the left and right sides of the support plate 3; the fixing bolts 9 on the left and right sides both pass through the through groove 11, and the adjacent sides are threadedly connected to the threaded groove 15, so that the fixing bolts 9 pass through the fixing block 4 and are threadedly connected to the support plate 3 at the same time, thereby improving the firmness of the installation between the support plate 3 and the fixing block 4, and facilitating subsequent disassembly and use, and the adjacent sides of the gaskets 10 on the left and right sides are fitted between the fixing block 4, so that the gasket 10 is used to increase the contact area between the bolt and the fixing block 4, thereby dispersing the pressure and avoiding local stress concentration, so as to reduce the wear and damage on the surface of the fixing block 4 and improve the stability of the installation of the fixing bolt 9.

[0028] After the replacement is completed, the replaced bucket tooth 2 is reset. At this time, the support plate 3 can be inserted into the bottom of the excavator bucket body 1 forward, and the plug-in blocks 16 on both sides are inserted into the inner wall of the plug-in groove 8. After resetting, the fixing bolts 9 on both sides are passed through the through groove 11 and threadedly connected with the threaded groove 15, thereby fixing the support plate 3 and the fixing block 4. At the same time, the washer 10 is used to increase the stability of the installation of the fixing bolt 9. Embodiment 3: On the basis of embodiment 2, in order to increase the sealing between the bucket teeth 2 and the excavator hopper body 1, improve its installation stability, and prevent external impurities from entering the slot 5, a gasket 6 is installed on the inner top wall of the slot 5, and a plurality of rubber protrusions 7 are installed on the inner wall of the gasket 6. A rubber pad 14 is installed on the top of the connecting plate 13; the plurality of rubber protrusions 7 are all in contact with the top of the bucket teeth 2, and the rubber protrusions 7 are in an extruded deformation state, thereby utilizing the cooperation between the rubber protrusions 7 and the gasket 6 to improve the sealing of the bucket teeth 2 and prevent impurities from entering the inner wall of the slot 5, thereby increasing its insertion stability and improving its service life. The plurality of rubber pads 14 are all in contact with the bottom of the excavator hopper body 1, so that when the support plate 3 drives the plurality of bucket teeth 2 to be installed between the excavator hopper body 1, the rubber pad 14 is squeezed and deformed, thereby increasing the installation stability between the support plate 3 and the excavator hopper body 1.

[0029] When the support plate 3 is inserted backward and reset, since the rubber pad 14 is installed on the top of the connecting plate 13, it gradually contacts the bottom of the excavator hopper body 1 and is squeezed and pushed to produce deformation, thereby increasing the stability of the insertion between the support plate 3 and the excavator hopper body 1. At the same time, a gasket 6 is installed on the inner wall of the slot 5, and a plurality of rubber protrusions 7 are installed on the inner wall of the gasket 6. When the bucket tooth 2 is gradually inserted into the inner wall of the slot 5, the plurality of rubber protrusions 7 are squeezed, thereby improving the plug-in sealing of the bucket tooth 2 and increasing the sealing of the slot 5 to prevent impurities from entering the slot 5 and corroding the bucket tooth 2, thereby increasing the service life of the bucket tooth 2.

[0030] Example 4: Based on Example 3, an excavator is proposed, including an excavator hopper.

[0031] In actual use, first rotate the fixing bolts 9 on both sides to disengage them from the threaded grooves 15, and at the same time pull the fixing bolts 9 out of the through grooves 11 on both sides and remove them. Then, the support plate 3 can be pulled forward to drive the plug-in blocks 16 on both sides to slide forward along the inner wall of the plug-in groove 8, and at the same time drive multiple bucket teeth 2 to gradually disengage from the bottom of the excavator bucket body 1. At this time, the bucket teeth 2 to be replaced can be removed, and the connecting plates 13 on both sides can be driven out of the mounting grooves 12, thereby eliminating the need for operators to disassemble and replace multiple bucket teeth 2 one by one, thereby reducing the complexity of disassembly and performing the operation. To improve the use effect of the excavator bucket body 1, after the replacement is completed, the replaced bucket tooth 2 is inserted into the inner wall of the mounting groove 12, and the connecting plates 13 on both sides are driven to be inserted into the inner wall of the mounting groove 12. At this time, the support plate 3 can be inserted into the bottom of the excavator bucket body 1, and the plug-in blocks 16 on both sides are driven to be inserted into the inner wall of the plug-in groove 8. After resetting, the fixing bolts 9 on both sides are passed through the through groove 11 and threadedly connected with the thread groove 15, thereby fixing the support plate 3 and the fixing block 4. At the same time, the washer 10 is used to increase the stability of the installation of the fixing bolt 9.

[0032] When the support plate 3 is inserted backward and reset, since the rubber pad 14 is installed on the top of the connecting plate 13, it gradually contacts the bottom of the excavator hopper body 1 and is squeezed and pushed to produce deformation, thereby increasing the stability of the insertion between the support plate 3 and the excavator hopper body 1. At the same time, a gasket 6 is installed on the inner wall of the slot 5, and a plurality of rubber protrusions 7 are installed on the inner wall of the gasket 6. When the bucket tooth 2 is gradually inserted into the inner wall of the slot 5, the plurality of rubber protrusions 7 are squeezed, thereby improving the plug-in sealing of the bucket tooth 2 and increasing the sealing of the slot 5 to prevent impurities from entering the slot 5 and corroding the bucket tooth 2, thereby increasing the service life of the bucket tooth 2.
