Description

Technical Field

[0001] This invention relates to the field of excavator technology, specifically to a combined excavator shovel tooth. Background Technology

[0002] Modular excavator teeth are an important component mounted on the excavator's bucket teeth, used to cut and crush the ground or rock during excavation operations. These teeth are typically made of high-quality alloy steel, possessing high hardness and wear resistance to ensure long-term use in harsh working environments. Modular excavator teeth usually feature a replaceable design, facilitating replacement when worn or damaged, extending the overall lifespan of the bucket teeth and reducing maintenance costs. Simultaneously, the structural design of the teeth effectively improves digging efficiency, reduces energy consumption, and enhances operational efficiency. During excavator use, correctly selecting appropriate modular excavator teeth and performing regular inspections and maintenance can ensure the excavator's normal operation, improve work efficiency, reduce maintenance costs, and ensure safe operation.

[0003] The shovel teeth are a crucial component mounted on the bucket teeth of an excavator, used to cut and crush the ground or rock during excavation operations. Shovel teeth are typically made of high-quality alloy steel, possessing high hardness and wear resistance to ensure long-term use in harsh working environments. Excavator shovel teeth are usually designed to be replaceable, facilitating replacement when they wear or become damaged, extending the overall lifespan of the bucket teeth and reducing maintenance costs.

[0004] Currently, most excavator teeth are integrated with the bucket. However, when the teeth wear out or are damaged, it may be necessary to replace the entire bucket instead of just the teeth, which increases maintenance costs. In addition, the integrated design also limits users from choosing different types of teeth according to their work needs. Therefore, it does not meet the existing needs. To address this, we have proposed a modular excavator teeth design. Summary of the Invention

[0005] This invention provides a modular excavator shovel tooth with a convenient disassembly mechanism connecting the tooth body to the shovel body. This allows for quick disassembly when maintenance or parts replacement is needed, reducing costs and addressing the issues mentioned in the background section. While most shovel teeth are integrated with the bucket, wear or damage to the teeth may necessitate replacing the entire bucket instead of just the teeth, increasing maintenance costs. Furthermore, the integrated design limits users' ability to select different types of shovel teeth based on their work requirements.

[0009] As an optional solution for the combined excavator shovel teeth described in this invention, the fixing clamp includes a first clamp body and a second clamp body. The second clamp body is disposed on the side of the first clamp body. A plurality of second fixing plates are connected to both sides of the first clamp body. A pivot pin is connected between the plurality of second fixing plates. The pivot pin is inserted into the side of the first clamp body and the second clamp body. The first clamp body, the second clamp body and the pivot pin are slidably engaged. A torsion spring is sleeved on the outside of the pivot pin.

[0010] As an optional solution for the combined excavator shovel teeth described in this invention, the bottom of the connecting bolt is integrally connected with a threaded post, the interior of the mounting groove is configured as a threaded inner wall, and the connecting bolt is threadedly engaged with the threaded post.

[0011] As an optional solution for the combined excavator shovel teeth described in this invention, the driving mechanism includes a pressing plate and a telescopic column. A plurality of pressing plates are provided, and the plurality of pressing plates are slidably connected to the ends of the connecting bolts. The pressing plates are disposed inside the threaded cylinder. The telescopic column is connected between the plurality of pressing plates. A spring is sleeved on the outside of the telescopic column, and the two ends of the spring are respectively connected between the plurality of pressing plates.

[0012] As an optional solution for the combined excavator shovel teeth described in this invention, the bottom of the pressing plate is connected to a sliding block, the sliding block is set as a rectangular block, the connecting bolt has a sliding groove inside, and the sliding block slides in conjunction with the sliding groove.

[0013] As an optional solution for the combined excavator shovel teeth of the present invention, the connecting bolt is further provided with a first airflow groove, the first airflow groove is configured as a "7" shaped groove, the sliding groove is connected to the first airflow groove, and the threaded column is provided with a second airflow groove inside, the first airflow groove and the second airflow groove are connected to each other.

[0014] As an optional solution for the combined excavator shovel teeth described in this invention, the fixing mechanism includes a piston rod and a piston disc.

[0016] The present invention has the following beneficial effects:

[0017] 1. This combined excavator shovel tooth, through the arrangement of the drive mechanism and the fixing mechanism, when the tooth body is engaged by the connecting bolt, the pressure plate is squeezed, causing the pressure plate to compress the spring and move the piston disc in the first airflow groove. This causes the airflow to flow in the opposite direction to the rubber ball, thus making the rubber ball contact and engage with the slot, completing the threaded connection between the tooth body and the shovel body. After releasing the pressure plate, the airflow returns along its original path, and the rubber ball engages with the slot. This allows for easy disassembly of the tooth body and shovel body through simple operations, such as squeezing the pressure plate and adjusting the airflow direction, to release the rubber ball from the slot. This facilitates quick disassembly when maintenance or parts replacement is needed, reducing costs.

[0018] After the rubber ball engages with the slot, it provides additional locking force, increasing the stability of the connection between the tooth body and the shovel body, and preventing accidental loosening or detachment. This solves the problem of most integrated shovel teeth and bucket designs, where when the shovel teeth are worn or damaged, the entire bucket may need to be replaced instead of just the shovel teeth, increasing maintenance costs. In addition, the integrated design also limits the user's ability to choose different types of shovel teeth according to their work needs.

[0019] 2. This combined excavator shovel teeth, through the setting of the piston, the piston and the drive mechanism cooperate, and the piston drives the airflow, which improves the effect of easy disassembly of the connection between the tooth body and the shovel body. At the same time, the piston drives the airflow to ensure that the airflow in the system remains stable, and prevents the connection force from being reduced due to the reduction of airflow.

[0020] 3. This combined excavator shovel teeth, through the setting of a pivot pin and torsion spring, and the cooperation of the pivot pin, torsion spring and fixing mechanism, when the fixing clamp is connected to the excavator tip, pressing the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate are twisted by the torsion spring, thereby clamping the first rotating shaft on the side of the excavator tip. This further improves the efficiency of maintenance personnel to perform repair and replacement operations more quickly. In addition, it also achieves the effect of adopting a multi-section detachable design. When the shovel teeth are damaged, only the damaged part needs to be replaced, instead of replacing the entire shovel teeth, which can save repair and replacement costs, making the whole solution better.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] This embodiment aims to address the issue that while most shovel teeth are integrated with the bucket, when the teeth wear or are damaged, it may be necessary to replace the entire bucket rather than just the teeth, increasing maintenance costs. Furthermore, the integrated design limits the user's ability to select different types of shovel teeth based on their work requirements. Please refer to [link to relevant documentation]. Figure 1-9 A combined excavator shovel tooth includes a shovel body 1110 and a tooth body 150. The tooth body 150 is located at the end of the shovel body 1110. A mounting groove 151 is provided on the side of the tooth body 150. A connecting bolt 160 is provided on the side of the mounting groove 151. A threaded cylinder 170 is provided at the end of the connecting bolt 160. A drive mechanism 180 is provided inside the threaded cylinder 170. A fixing mechanism 190 is provided at the bottom of the drive mechanism 180. The fixing mechanism 190 works in conjunction with the drive mechanism 180.

[0034] A plurality of tooth bodies 150 are provided, and the plurality of tooth bodies 150 are connected to the end of the shovel body 1110. The tooth body 150 includes a fixing clamp and a digging tip. The fixing clamp is detachably connected to the end of the shovel body 1110, and the digging tip is detachably connected to the end of the fixing clamp. The digging tip is connected to a first fixing plate 121. A plurality of first fixing plates 121 are provided, and a first rotating shaft 122 is connected between the plurality of first fixing plates 121. The end of the fixing clamp is slidably engaged with the side of the first rotating shaft 122.

[0035] The shovel is connected to the digging tip via a fixing clamp, and the clamp and digging tip are connected by a first rotating shaft 122, making the entire shovel structure more stable and secure, less prone to loosening or falling off. The detachable connection design facilitates maintenance and replacement of damaged parts. When the fixing clamp, digging tip, or other parts need to be replaced or repaired, the corresponding parts can be easily disassembled for maintenance. Furthermore, multiple fixing plates connected by the first rotating shaft 122 allow for relative movement between the fixing clamp and the digging tip, thereby adjusting the shovel's working state and angle, enhancing its applicability and flexibility.

[0036] The bottom of the connecting bolt 160 is integrally connected with a threaded post 161. The interior of the mounting groove 151 is set as a threaded inner wall. The connecting bolt 160 and the threaded post 161 are threadedly engaged. The drive mechanism 180 includes a pressing plate 181 and a telescopic post 182. Several pressing plates 181 are provided. Several pressing plates 181 are slidably connected to the end of the connecting bolt 160 and are located inside the threaded cylinder 170. The telescopic post 182 is connected between several pressing plates 181. A spring 183 is sleeved on the outside of the telescopic post 182. The two ends of the spring 183 are respectively connected between several pressing plates 181.

[0037] The connecting bolt 160 and threaded post 161 are connected by a threaded connection, making the connection more secure and reliable, less prone to loosening or falling off, and improving operational stability and safety. The threaded connection design facilitates the installation and removal of the pressing plate 181 and the telescopic post 182, making maintenance and component replacement easier and more efficient. The design of the telescopic post 182 allows the spring 183 to act as a buffer and stabilizer between the pressing plates 181, while also saving space and making the overall structure of the drive mechanism 180 more compact.

[0038] A sliding block 184 is connected to the bottom of the pressing plate 181. The sliding block 184 is a rectangular block. A sliding groove 162 is provided inside the connecting bolt 160. The sliding block 184 and the sliding groove 162 are slidably engaged. The connecting bolt 160 is also provided with a first airflow groove 163. The first airflow groove 163 is a "7" shaped groove. The sliding groove 162 and the first airflow groove 163 are connected. A second airflow groove 164 is provided inside the threaded column 161. The first airflow groove 163 and the second airflow groove 164 are connected.

[0039] The sliding engagement between the sliding block 184 and the sliding groove 162 reduces friction between components, lowers wear, and extends service life, making the operation of the drive mechanism 180 smoother and more stable. The rectangular block design better secures the pressing plate 181, improving the stability and firmness of the connection and ensuring that the drive mechanism 180 is less likely to loosen or fall off during operation. The connection between the first airflow groove 163 and the second airflow groove 164 allows airflow to circulate inside the drive mechanism 180, improving the stability and reliability of the equipment.

[0040] In this embodiment: With the drive mechanism 180 and the fixing mechanism 190, when the tooth body 150 is engaged by the connecting bolt 160, the pressing plate 181 is squeezed, causing the pressing plate 181 to compress the spring 183, which in turn moves the piston disc 192 in the first airflow groove 163. This causes the airflow to flow in the opposite direction to the rubber ball, thereby engaging the rubber ball 193 with the slot 194. After the tooth body 150 and the shovel body 1110 are connected by threads, the pressing plate 181 is released, the airflow returns along its original path, and the rubber ball engages with the slot 194. This allows for easy disassembly of the tooth body 150 and the shovel body 1110 by simple operations such as squeezing the pressing plate 181 and adjusting the airflow direction. This also allows for quick disassembly when maintenance or replacement of parts is needed, reducing costs.

[0041] After the rubber ball engages with the slot 194, it provides additional locking force, increasing the stability of the connection between the tooth body 150 and the shovel body 1110, and preventing accidental loosening or detachment. This solves the problem of most integrated shovel teeth and bucket designs, where the entire bucket may need to be replaced instead of just the teeth when the teeth are worn or damaged, increasing maintenance costs. In addition, the integrated design also limits the user's ability to select different types of shovel teeth according to their work needs.

[0042] Example 2

[0043] This embodiment aims to address the problem of insufficient airtightness inside the first airflow groove 163. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figure 1-9 The fixing mechanism 190 includes a piston rod 191 and a piston disc 192. The piston rod 191 is connected to the side of the sliding block 184, and the piston disc 192 is connected to the bottom of the piston rod 191. The piston disc 192 is slidably connected to the first airflow groove 163, and the piston disc 192 is fitted against the inner wall of the first airflow groove 163. A rubber ball is connected to the end of the second airflow groove 164. A threaded hole 200 is opened on the side of the shovel body 1110. The threaded post 161 is inserted into the interior of the mounting groove 151 and threadedly connected to the threaded hole 200. A slot 194 is opened inside the mounting groove 151. The rubber ball is slidably engaged with the slot 194. A threaded cap 195 is connected to the end of the threaded cylinder 170.

[0044] The piston disc 192 is fitted to the inner wall of the first airflow groove 163 to achieve a good sealing effect, prevent gas leakage, and ensure stable pressure and airtightness inside the airflow channel.

[0045] In this embodiment, the piston is configured to cooperate with the drive mechanism 180. The piston drives the airflow, which improves the ease of disassembling the connection between the tooth body 150 and the shovel body 1110. At the same time, the piston-driven airflow ensures that the airflow in the system remains stable, preventing the connection force from decreasing due to reduced airflow.

[0046] Example 3

[0047] This embodiment aims to address the problem of waste caused by replacing the entire shovel tooth when only a portion of it is damaged. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1-9 The fixing clamp includes a first clamp body and a second clamp body. The second clamp body is disposed on the side of the first clamp body. Several second fixing plates 196 are connected to both sides of the first clamp body. A pivot pin 114 is connected between the several second fixing plates 196. The pivot pin 114 is inserted into the side of the first clamp body and the second clamp body. The first clamp body, the second clamp body and the pivot pin 114 are slidably engaged. A torsion spring 115 is sleeved on the outside of the pivot pin 114.

[0048] The design of the first clamp, the second clamp, and the pivot pin 114 enables multi-point fixation, providing a more stable fixing effect, ensuring a firm connection of related components, and preventing loosening or detachment.

[0049] In this embodiment, the combination of pivot pin 114 and torsion spring 115, along with the cooperation of pivot pin 114, torsion spring 115, and fixing mechanism 190, allows the fixing clamp 111 to be connected to the digging tip 120. Pressing the first clamping plate 112 and the second clamping plate 113 causes the first clamping plate 112 and the second clamping plate 113 to twist via torsion spring 115, thereby clamping the first rotating shaft 122 on the side of the digging tip 120. This further improves the efficiency of maintenance personnel in performing repairs and replacements more quickly. Furthermore, the multi-section detachable design allows for replacement of only the damaged part when the shovel teeth are damaged, rather than replacing the entire shovel teeth, saving on repair and replacement costs and making the overall solution better.
