Description
Technical Field
[0001] The utility model relates to the technical field of excavator bucket teeth, in particular to an excavator bucket tooth which is convenient for disassembly and assembly. Background Technique
[0002] The bucket tooth is an important part on the excavator. Similar to human teeth, it is a vulnerable part. The bucket tooth is mainly fixed on the excavator bucket through bolts. Due to the design of the bucket tooth, it can prompt the excavator bucket to easily dig open the hard ground. The manufacturing process of the bucket tooth includes sand casting, forging casting, precision casting, etc.
[0003] The existing disassembly and assembly of excavator bucket teeth are mainly fixed on the bucket through bolts. As the bucket continuously shovels media such as soil, sand, and stones, it is inevitable that media such as soil, fine sand, and small stones will enter the gaps at the fixed bolt positions. When the bucket tooth needs to be replaced, the bolts are difficult to turn. Moreover, the bolts for fixing the bucket tooth are all long bolts, so that the bucket tooth needs to be continuously rotated when disassembling, resulting in a more complex disassembly of the bucket tooth, a long disassembly time, and thus affecting the replacement progress of the bucket tooth. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing bucket teeth, the utility model provides an excavator bucket tooth which is convenient for disassembly and assembly, has the advantages of realizing the rapid installation and disassembly of the bucket tooth, and solves the technical problem of complex disassembly and assembly of the excavator bucket tooth.
[0005] The utility model provides the following technical scheme: An excavator bucket tooth which is convenient for disassembly and assembly, including a bucket, and further including:
[0006] A linking structure, fixedly installed on the top of the bucket. An installation groove is opened at the bottom end face of the bucket. A bucket tooth is installed in the installation groove. An installation rod is fixedly connected to the bucket tooth, and the installation rod extends into the interior of the installation groove;
[0007] An installation bolt, threadedly connected to the installation rod. The installation rod is fixedly connected to a tooth sleeve through the installation bolt. An installation hole is opened at the corresponding position of the tooth sleeve and the installation bolt. A soil-removing groove is opened on the top surface of the tooth sleeve.
[0008] Preferably, the interior of the installation groove includes:
[0009] A hinge, rotatably installed in the installation groove;
[0010] A clamping plate, rotatably hinged to the hinge;
[0011] A magnetic block, fixedly arranged inside the clamping plate.
[0012] Preferably, the installation groove further includes:
[0013] A spring, fixedly connected to the middle of the left side wall of the installation groove;
[0014] A push plate, fixedly connected to the end of the spring away from the installation groove.
[0015] Preferably, the installation rod includes:
[0016] A barb, fixedly connected to the left end of the installation rod;
[0017] A magnetic plate, fixedly arranged inside the barb;
[0018] A top block, fixedly connected to the outer surface of the installation rod and located outside the barb.
[0019] Preferably, the magnetic block is arranged with the N pole on the upper side and the S pole on the lower side, and the magnetic plate is arranged with the S pole on the upper side and the N pole on the lower side.
[0020] Compared with the prior art, the present utility model has the following beneficial effects:
[0021] 1. By designing components such as hinges, clamping plates, magnetic blocks, barbs, magnetic plates, and top blocks, when installing the bucket tooth, align the installation rod with the installation groove, then hold the bucket tooth and push the installation rod into the installation groove, causing the installation rod to push the push plate to slide and the spring to store energy. At this time, the barb will push against the clamping plate and deflect upward along the hinge. After the barb passes over the clamping plate, the clamping plate will deflect and reset under its own weight. Then release the bucket tooth, causing the spring to drive the push plate to push the installation rod to slide in the reverse direction, resulting in the barb contacting the clamping plate and being stuck by the clamping plate. When the bucket tooth needs to be replaced, push the bucket tooth to slide inward into the installation groove, causing the top block to push the clamping plate to deflect upward again, and then the spring will use the push plate to push the installation rod away again. At this time, the magnetic plate on the barb just has the same magnetic pole as the magnetic block on the clamping plate, causing the magnetic block to be affected by the magnetic repulsive force of the magnetic plate, and then the installation rod will drive the bucket tooth to continue sliding outward from the installation groove. At this time, the staff can remove the bucket tooth from the digging bucket. The above settings make the replacement of the bucket tooth more convenient and fast.
[0022] 2. By designing the magnetic plate and the magnetic block, when the installation rod is inside the installation groove, since the barb is stuck by the clamping plate, the magnetic pole of the magnetic plate on the barb is just opposite to the magnetic pole of the magnetic block at this time. Then, using the magnetic attraction force of the magnetic plate on the magnetic block, the barb is fixed at the clamping plate, thereby fixing the installation rod, and indirectly improving the stability of the bucket tooth on the digging bucket.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer to Figures 1 - 5 , a bucket tooth of an excavator that is convenient for disassembly and assembly, including a digging bucket 1, a linking structure 2 is fixedly installed at the top of the digging bucket 1, an installation groove 3 is opened at the bottom end face of the digging bucket 1, a bucket tooth 4 is installed in the installation groove 3, a mounting rod 5 is fixedly welded on the bucket tooth 4, the mounting rod 5 extends into the interior of the installation groove 3, a mounting bolt 6 is threadedly connected to the mounting rod 5, the mounting rod 5 is fixedly connected to a tooth sleeve 7 through the mounting bolt 6, a mounting hole 8 is opened at the corresponding position of the tooth sleeve 7 and the mounting bolt 6, and a soil retreating groove 9 is opened at the top surface of the tooth sleeve 7.
[0031] Please refer to Figures 1 - 5 , a hinge 31 is rotatably installed inside the installation groove 3, a clamping plate 32 is rotatably hinged on the hinge 31, facilitating the deflection of the clamping plate 32 along the hinge 31, and a magnetic block 33 is fixedly arranged inside the clamping plate 32.
[0032] Please refer to Figures 1 - 5 , a spring 34 is fixedly welded to the middle of the left side wall of the installation groove 3, and a push plate 35 is fixedly welded to the end of the spring 34 away from the installation groove 3, facilitating the sliding of the mounting rod 5.
[0033] Please refer to Figures 1 - 5, a barb 51 is fixedly welded to the left end of the mounting rod 5, a magnetic plate 52 is fixedly arranged inside the barb 51, and a top block 53 is fixedly welded to the outer surface of the mounting rod 5 outside the barb 51, ensuring that the barb 51 can be caught by the clamping plate 32, thereby fixing the mounting rod 5 and facilitating the disassembly of the mounting rod 5 and the bucket tooth 4.
[0034] Please refer to Figures 1 - 5 , the magnetic block 33 is arranged with N pole on the upper side and S pole on the lower side, and the magnetic plate 52 is arranged with S pole on the upper side and N pole on the lower side, facilitating the fixing of the mounting rod 5 by the magnetic attraction between the magnetic plate 52 and the magnetic block 33. After the clamping plate 32 deflects, the magnetic repulsion force between the magnetic plate 52 and the magnetic block 33 is used to promote the deflection of the clamping plate 32, thus facilitating the removal of the mounting rod 5 from the mounting groove 3.
[0035] Working principle: When installing the bucket tooth 4, align the mounting rod 5 with the mounting groove 3, and then hold the bucket tooth 4 and push the mounting rod 5 into the mounting groove 3, so that the mounting rod 5 pushes the push plate 35 to slide and causes the spring 34 to store energy. At this time, the barb 51 will push against the clamping plate 32 and deflect upward along the hinge 31. After the barb 51 passes over the clamping plate 32, the clamping plate 32 deflects and resets under its own weight. Then release the bucket tooth 4, so that the spring 34 will drive the push plate 35 to push the mounting rod 5 to slide in the reverse direction, causing the barb 51 to contact and be caught by the clamping plate 32. When the bucket tooth 4 needs to be replaced, push the bucket tooth 4 to slide inside the mounting groove 3, so that the top block 53 will push the clamping plate 32 to deflect upward again, and then the spring 34 will use the push plate 35 to push the mounting rod 5 away again. At this time, the magnetic plate 52 on the barb 51 and the magnetic block 33 on the clamping plate 32 are just in the same magnetic pole, so that the magnetic block 33 will be affected by the magnetic repulsion force of the magnetic plate 52, and then the mounting rod 5 will drive the bucket tooth 4 to continue to slide outside the mounting groove 3. At this time, the staff can remove the bucket tooth 4 from the digging bucket 1. The above settings make the replacement of the bucket tooth 4 more convenient and fast. Secondly, when the mounting rod 5 is inside the mounting groove 3, since the barb 51 is caught by the clamping plate 32, the magnetic pole of the magnetic plate 52 on the barb 51 is just opposite to the magnetic pole of the magnetic block 33. Then, using the magnetic attraction of the magnetic plate 52 to the magnetic block 33, the barb 51 is fixed at the clamping plate 32, thereby fixing the mounting rod 5, and indirectly improving the stability of the bucket tooth 4 on the digging bucket 1.
