The two groups of ear plates 2 are in a parallel state and welded to the upper part of the rear wall of the bucket body 1. The bucket body 1 is connected to the long arm of the excavator through the ear plates 2 to adjust the angle of the bucket body 1.

[0031] Combined with Figure 1 , Attachment Figure 3 With attached Figure 6 As shown, a reinforcing support bar 3 is integrally formed at the bottom of the bucket body 1, a shovel tooth 4 is inserted and installed at the front end of the reinforcing support bar 3, the front end of the reinforcing support bar 3 passes through the bottom of the bucket body 1, and a slot 2 15 is installed on the inner side of the front end, and an insert block 16 is installed at the rear end of the shovel tooth 4, a connecting bolt 3 17 is installed through the upper side of the front end of the reinforcing support bar 3, and the lower end of the connecting bolt 3 17 passes into the inside of the slot 2 15, and a threaded hole 19 for inserting the connecting bolt 3 17 is provided between the upper and lower side walls of the insert block 16, and the connecting bolt 3 17 is inserted into the threaded hole 19 Inside, the insert block 16 is fixedly installed in the slot 2 15, and the shovel tooth 4 is installed, which is convenient for disassembly of the shovel tooth 4 later. The rear end of the shovel tooth 4 contacts the front end of the reinforcing support bar 3. After the connecting bolt 3 17 is inserted into the threaded hole 19, the shovel tooth 4 is prevented from shaking at the front end of the reinforcing support bar 3. The upper side of the front end of the reinforcing support bar 3 is provided with a groove 2 18 for fitting the top of the connecting bolt 3 17. The top of the connecting bolt 3 17 is located in the groove 2 18, and the material will not hit the top of the connecting bolt 3 17 laterally, preventing the connecting bolt 3 17 from loosening.

[0032] Combined with Figure 2 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 7 As shown, the bottom of the bucket body 1 is provided with a plurality of groups of crushing protrusions 7, and a protrusion mounting assembly is installed between the lower sides of the plurality of groups of reinforcing support bars 3. The protrusion mounting assembly fixes the plurality of groups of crushing protrusions 7 on the bottom of the bucket body 1. The protrusion mounting assembly includes a mounting cross plate 6, and the lower side of the mounting cross plate 6 is equidistantly provided with a plurality of groups of slots 9 for inserting the crushing protrusions 7. The slots 9 are of a rectangular structure, and the side walls of the crushing protrusions 7 are in contact with the side walls of the slots 9 to prevent the crushing protrusions 7 from rotating inside the slots 9. A connecting bolt passes through the bottom of the slots 9. A threaded hole 11 is provided on the top of the crushing protrusion 7 for inserting the connecting bolt 10. The connecting bolt 10 passes through the mounting cross plate 6 and is inserted into the threaded hole 11 to fix the crushing protrusion 7 inside the slot 9. A groove 12 is provided on the upper side of the mounting cross plate 6 for embedding the top of the connecting bolt 10. The top of the connecting bolt 10 and the upper side of the mounting cross plate 6 are in contact with the bottom of the bucket body 1 respectively. The top of the connecting bolt 10 is limited by the bucket body 1 to prevent the connecting bolt 10 from rotating upward inside the mounting cross plate 6 and becoming loose.

[0033] Combined with Figure 3 and attached Figure 4As shown, the lower side of the reinforcing support bar 3 is provided with a limiting groove 5 for sliding insertion of the mounting cross plate 6, and the end face of the limiting groove 5 is an inverted "convex" shape structure. When the mounting cross plate 6 passes into multiple groups of limiting grooves 5, multiple groups of crushing protrusions 7 pass through the notches of the limiting grooves 5 in sequence. Multiple groups of connecting bolts 8 pass through the mounting cross plate 6, and the mounting cross plate 6 is fixedly installed at the bottom of the bucket body 1 through the connecting bolts 8.

[0034] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a protective strip 13 is installed on the outer side of the angle between the bottom plate and the side plate of the bucket body 1 to protect the edges and corners of the bucket body 1. The cross-section of the protective strip 13 is an L-shaped structure and is fixedly connected to the bucket body 1 with multiple sets of bolts. A multiple sets of positioning holes 14 are provided on the side wall of the lower side of the L-shaped structure close to the reinforcing support bar 3. The two ends of the mounting cross plate 6 are respectively inserted into the corresponding positioning holes 14 to limit the two sides of the mounting cross plate 6, so that the mounting cross plate 6 can be installed on the bottom of the bucket body 1, and the two sides of the mounting cross plate 6 are subsequently limited to prevent the lateral movement of the mounting cross plate 6 from causing shear force on the multiple sets of connecting bolts 8 when hitting large pieces of material. The crushing protrusion 7 is an inverted trapezoidal boss, and the lower side of the protective strip 13 is on the same plane as the lower side of the reinforcing support bar 3. The lower end of the crushing protrusion 7 is located below the reinforcing support bar 3, so that the crushing protrusion 7 can first contact the large piece of material.

[0035] The specific usage is as follows:

[0036] When the long-arm excavator is used to scoop materials, the existing hydraulic long arm is used to drive the bucket body 1 to move and adjust the angle to shovel materials. When encountering large pieces of materials that cannot be shoveled, the long arm of the excavator is used to adjust the angle of the bucket body 1, and the bottom of the bucket body 1 is facing downward. The long arm of the excavator drives the bucket body 1 to move downward, and the multiple groups of crushing protrusions 7 at the bottom of the bucket body 1 contact with the large pieces of materials to knock the large pieces of materials. The force-bearing area at the lower end of the crushing protrusion 7 is small, and the large pieces of materials can be cracked to form multiple groups of relatively small pieces. The long arm of the excavator continues to move the bucket body 1 downward, and the multiple groups of crushing protrusions 7 are pressed on the relatively small block materials. The relatively small block materials are continuously crushed by the lower ends of the multiple groups of crushing protrusions 7 to be pressed into small pieces of materials, so that the bucket body 1 is convenient for scooping up the materials;

[0037] Each group of crushing protrusions 7 is independently installed on the lower side of the mounting cross plate 6, and each group of mounting cross plate 6 is independently installed at the bottom of the bucket body 1. When a group of crushing protrusions 7 is damaged, a group of protection strips 13 is removed, and the mounting cross plate 6 where the group is located is pulled out from the limiting groove 5. Then, a group of mounting cross plate 6 and the multiple groups of crushing protrusions 7 installed on the upper side thereof can be removed, and a new group of crushing protrusions 7 can be replaced on the mounting cross plate 6, and then the mounting cross plate 6 can be installed to the bottom of the bucket body 1, and the maintenance cost is low.
