Description

Technical Field

[0001] This utility model belongs to the field of excavator technology, specifically relating to an excavation structure and excavation. Background Technology

[0002] Excavators are multi-purpose earthmoving and rock-moving construction machines, primarily used for excavation and loading of earth and rock. They can also perform land leveling, slope trimming, and hoisting operations, and are widely used in various engineering construction projects. The excavating structure is a crucial component of an excavator. Currently, excavating structures are typically either flat or rack-and-tooth shaped. However, these two structural types are usually mounted on different excavating structures. When replacement is needed, the entire excavating structure must be disassembled and the other structure installed, which is not only time-consuming and labor-intensive but also increases the probability of damage to the excavating structure, causing unnecessary trouble for the user.

[0003] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an excavation structure and an excavator.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0012] In one or more embodiments of this utility model, the fixing block is provided with a connecting hole to facilitate threaded connection with the drive shaft, thereby allowing the fixing block to slide via the drive shaft.

[0013] In one or more embodiments of this utility model, the fixing block is provided with an arc groove and a slope groove that match the upper semicircular surface and inclined surface of the adjusting shovel tooth, so that the fixing block can abut against the adjusting shovel tooth, thereby ensuring that the adjusting shovel tooth is not easy to rotate and fall out when not in use, and that the adjusting shovel tooth is not easy to shake during use.

[0014] In one or more embodiments of this utility model, a pair of limiting blocks are fixed on the side wall of the arc groove for locking in the limiting slot, thereby fixing the adjusting shovel teeth and making it difficult for the adjusting shovel teeth to rotate or move, thus ensuring the stability of the adjusting shovel teeth.

[0015] In one or more embodiments of this utility model, a pair of limiting slots matching the limiting blocks are chiseled on the semicircular surfaces of the plurality of adjusting shovel teeth.

[0016] In one or more embodiments of this utility model, the rotating support shaft has multiple threaded holes, the adjusting shovel teeth are mounted on a fixing bolt, and one end of the fixing bolt is threadedly connected to the rotating support shaft.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1-6 As shown, an excavation structure and excavator according to one embodiment of the present invention include: an excavation bucket 1 and an adjustment mechanism 2.

[0030] like Figures 1-4 As shown, the bottom of the excavator bucket 1 has a bottom adjustment cavity 105, which provides space for the sliding of the fixed block 206. The excavator bucket 1 includes a side support plate 101, and a supporting bottom plate 102 and an upper fixed horizontal plate 104 are fixedly connected to the upper and lower parts of the side support plate 101, respectively. A pair of supporting side plates 103 are fixedly connected between the supporting bottom plate 102 and the upper fixed horizontal plate 104 to facilitate excavation and make it easier for workers to operate.

[0031] like Figures 1-6 As shown, the adjustment mechanism 2 is installed on the excavator bucket 1. The adjustment mechanism 2 includes a rotating support shaft 201, which is rotatably mounted on the excavator bucket 1. Multiple fixed shovel teeth 202 are rotatably mounted on the rotating support shaft 201. An adjusting shovel tooth 203 is positioned between a pair of fixed shovel teeth 202. The cooperation of the multiple fixed shovel teeth 202 and the adjusting shovel tooth 203 enables adjustments for leveling excavation and rack and pinion excavation. Each of the multiple fixed shovel teeth 202 and the adjusting shovel tooth 203 has a semi-circular surface and an inclined surface. The multiple adjusting shovel teeth 203 are fixedly mounted on the rotating support shaft 201. A fixing block 206 is slidably disposed within the bottom adjustment cavity 105 to lock the adjusting shovel tooth 203, preventing it from rotating easily.

[0032] like Figures 1-4 As shown, a drive shaft 204 is inserted into the bottom adjustment cavity 105 to drive the fixed block 206 to move, so that the fixed block 206 can abut against the adjustment shovel tooth 203. When the adjustment shovel tooth 203 is not in use, it can prevent the adjustment shovel tooth 203 from rotating and falling down. When in use, the adjustment shovel tooth 203 will not rotate, thus facilitating digging.

[0033] Among them, a number of fixed bearings 205 are fixedly connected between the drive shaft 204 and the excavator bucket 1. One end of the drive shaft 204 is threadedly connected to the fixed block 206, so that the rotation of the drive shaft 204 will not be affected, and thus can stably drive the fixed block 206 to slide.

[0034] In addition, a pair of limiting grooves are cut into the side wall of the bottom adjustment cavity 105 to provide space for the sliding of the side limiting slider 207. Both sides of the fixed block 206 are fixed with side limiting sliders 207 that match the limiting grooves to support the fixed block 206, so that the fixed block 206 cannot rotate and will not change direction when sliding.

[0035] like Figures 1-6As shown, the fixed block 206 has a connecting hole 208 for easy threaded connection with the drive shaft 204, allowing the fixed block 206 to slide via the drive shaft 204. The fixed block 206 also has an arc groove 210 and a slope groove 211 that match the upper semicircular surface and inclined surface of the adjusting shovel tooth 203, allowing the fixed block 206 to abut against the adjusting shovel tooth 203. This ensures that the adjusting shovel tooth 203 is not easily rotated or fallen out when not in use, and that it is not easily shaken during use.

[0036] like Figures 1-6 As shown, a pair of limiting blocks 209 are fixed on the side wall of the arc groove 210, used to lock into the limiting slot 213, thereby fixing the adjusting teeth 203 and making it difficult for the adjusting teeth 203 to rotate or move, thus ensuring the stability of the adjusting teeth 203. A pair of limiting slots 213 matching the limiting blocks 209 are drilled on the semi-circular surface of multiple adjusting teeth 203. Multiple threaded holes are drilled on the rotating support shaft 201, and fixing bolts 212 are installed on the adjusting teeth 203. One end of the fixing bolt 212 is threadedly connected to the rotating support shaft 201.

[0037] An excavator comprising the above-mentioned excavation structure.

[0038] In practical use, when it is necessary to... Figure 1 Adjusting to medium state Figure 5 First, rotate the drive shaft 204 to move the fixed block 206, so that the fixed block 206 no longer obstructs the adjusting shovel teeth 203, allowing the adjusting shovel teeth 203 to rotate and move. After rotating the multiple adjusting shovel teeth 203 until the multiple fixed shovel teeth 202 are aligned, rotate the drive shaft 204 again to move the fixed block 206. Then, the drive shaft 204 abuts against the adjusting shovel teeth 203, and the limiting block 209 can be locked in the limiting slot 213, thus fixing the adjusting shovel teeth 203 and preventing them from rotating during use.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
