Description

Technical Field

[0001] This invention relates to the field of excavator bucket technology, and in particular to an excavator bucket capable of loosening materials and soil. Background Technology

[0002] Excavators play a vital role in many fields such as construction, mining, and agricultural reclamation. As one of the important components of an excavator, the bucket is used to hold materials during the excavation process.

[0003] In the prior art: Chinese patent CN110714494A, published on January 21, 2020, discloses a loosening excavator bucket. This design prevents soil or rocks from falling out of the bucket after being lifted. As the bucket descends, the serrated edge of the rotating disc further breaks up the material, preventing compaction due to the bucket's curved or flat bottom surface. This loosening action facilitates digging. However, when loosening hard soil layers, this patented technology is inefficient using only a conventional bucket, resulting in poor soil loosening and hindering subsequent digging operations.

[0004] Chinese patent CN111305295A, published on April 7, 2020, discloses an excavator with a mother-and-child bucket design, which can save a significant amount of time required for bucket replacement, enabling multi-purpose use and improving production efficiency. However, in this patented technology, when excavating materials that are highly viscous or easily compacted, the material tends to accumulate in the bucket, forming compacted lumps. The bucket lacks an effective loosening function, making it difficult for the material to be smoothly discharged during unloading, thus affecting work efficiency.

[0005] To address this, an excavator bucket capable of loosening materials and soil is proposed, which can adapt to excavating materials under complex working conditions and has the function of loosening internal materials. Summary of the Invention

[0006] The purpose of this invention is to provide an excavator bucket that can loosen materials and soil, which can loosen the soil when excavating hard materials, and can also loosen the material inside the bucket, reduce the compaction of the material, and facilitate unloading.

[0008] Furthermore, the first mounting sleeve and the second mounting sleeve are alternately arranged on the main shaft, and adjacent first mounting sleeves and second mounting sleeves are connected by a support rod.

[0009] Furthermore, the disturbance component includes a fixed cylinder, one end of which is connected to the second mounting sleeve. A transmission rod is slidably disposed inside the fixed cylinder, and a push block is bolted to the front side of the transmission rod. The push block is slidably disposed inside the fixed cylinder. A pressure spring is disposed between the push block and the inner wall of the fixed cylinder, and oil is filled between the push block and the inner wall of the fixed cylinder.

[0010] Furthermore, the mounting plate is provided with a transmission component on the side facing the inside of the bucket structure, and the transmission component contacts the digging bucket to transmit the vibration of the eccentric block.

[0011] Furthermore, the transmission component includes a connecting block, one end of which is connected to the mounting plate, and the other end of which is connected to a movable block, and the movable block is provided with a connecting rod; the inner wall of the digging bucket is connected to a transmission plate, the transmission plate is provided with a slot, the movable block is movably inserted into the slot and the connecting rod is in contact with the transmission plate.

[0012] Furthermore, the mounting plate includes an upper support plate and a lower support plate.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Example 1 Please see Figure 1-7 An excavator bucket capable of loosening materials and soil includes a bucket structure 1 and a soil loosening structure 2. The bucket structure 1 includes a digging bucket 11, a connecting seat 12 welded to the top of the digging bucket 11, a first hinge plate 13 provided at the bottom of the front side of the digging bucket 11, a plurality of main soil breaking teeth 14 bolted to the front side of the first hinge plate 13, and extension components 15 bolted to both sides of the digging bucket 11. The bucket structure 4, with its well-designed breaking teeth and extension components, can not only adapt to different excavation scenarios and expand the excavation range, but also enhance the breaking ability and prevent materials from falling.

[0023] The soil loosening structure 2 includes two sets of rotating frames 21, which are welded to both sides of the top of the excavator bucket 11. Connecting frames 22 are fitted onto the surface of each rotating frame 21. A mounting plate 23 is bolted between the interior of the two connecting frames 22. Two bearing seats 24 are bolted to the rear side of the mounting plate 23, and a main shaft 25 passes through the opposite sides of the two bearing seats 24. A soil loosening component 26 is fitted onto the surface of the main shaft 25. Conducting components 27 are bolted to both sides of the rear side of the mounting plate 23, and the conducting components 27 cooperate with the excavator bucket 11. By setting up the soil loosening structure 2... The loosening structure 2 can loosen the material inside the bucket structure 1 after the bucket structure 1 has finished digging. The rotating main shaft 25 can drive the loosening component 26 and the transmission component 27 to transmit vibration to the material inside the bucket structure 1. The vibration achieves the effect of loosening the material. The bucket structure 1, through the extension component 15, can increase the loosening area of ​​the digging bucket 11 on the material, thereby improving the subsequent digging efficiency. In addition, the extension component 15 can also adjust the angle of the soil breaking teeth cutting into the material, which can improve the loosening effect when facing materials with different hardness.

[0024] The soil loosening assembly 26 includes a first mounting sleeve 261 and a second mounting sleeve 262, both of which are fitted onto the surface of the main shaft 25. Soil loosening teeth 263 are welded to the surface of the first mounting sleeve 261. A disturbance element 264 is bolted to the rear side of the second mounting sleeve 262. Eccentric blocks 265 are fitted onto both sides of the surface of the main shaft 25. By setting the soil loosening assembly 26, the main shaft 25 can be driven to rotate by an external hydraulic motor, causing the main shaft 25 to synchronously drive the first mounting sleeve 261, the second mounting sleeve 262, and the eccentric blocks 265 to rotate. The first mounting sleeve 261 and its loosening teeth 263 rotate with the main shaft 25. As they rotate, the loosening teeth 263 continuously cut into the material, breaking and loosening it. At the same time, the disturbance component 264 behind the second mounting sleeve 262 and the eccentric block 265 on the main shaft 25, during rotation, due to the centrifugal force generated by the eccentric block 265 and the structural characteristics of the disturbance component 264 itself, cause the disturbance component 264 to exert additional disturbance and squeezing forces on the material, further breaking and loosening the material. Multiple loosening methods work together to achieve a better loosening effect.

[0025] The first mounting sleeve 261 and the second mounting sleeve 262 are each in multiples, and are distributed at intervals on the surface of the main shaft 25. A support rod 3 is movably provided on the side of the first mounting sleeve 261 near the second mounting sleeve 262, and the support rod 3 is bolted to the side of the second mounting sleeve 262 near it. By setting the first mounting sleeve 261 and the second mounting sleeve 262 to be distributed at intervals on the surface of the main shaft 25, the continuity and stability of the loosening teeth 263 and the disturbance component 264 during operation are ensured, and the loosening effect is avoided due to uneven force on individual components, thus improving the reliability of the loosening structure 2. The support rod 3 can also restrict the position of the second mounting sleeve 262.

[0026] The disturbance component 264 includes a fixed cylinder 264a, which is bolted to the side of the second mounting sleeve 262. A transmission rod 264b is slidably disposed inside the fixed cylinder 264a. A push block 264c is bolted to the front side of the transmission rod 264b and slidably disposed inside the fixed cylinder 264a. A compression spring 264d is disposed between the push block 264c and the inner wall of the fixed cylinder 264a, and oil is filled between the push block 264c and the inner wall of the fixed cylinder 264a. By setting the disturbance component 264, when the rotating frame 21 drives the connecting frame 22 and the mounting plate 23 to approach the digging bucket 11, due to the digging… The accumulation of material in the shovel bucket 11 causes the transmission rod 264b to come into contact with the material first. The material exerts an impact force on the transmission rod 264b, and the push block 264c slides backward in the fixed cylinder 264a, compressing the pressure spring 264d and squeezing the oil. The oil buffers the impact force through damping. Subsequently, the elastic restoring force of the pressure spring 264d pushes the push block 264c to return to its original position. The oil then generates a certain resistance to the return motion of the push block 264c, causing the push block 264c to reciprocate. This reciprocating motion transmits the force to the outside through the transmission rod 264b, continuously applying a disturbance force to the material, thereby effectively loosening the material.

[0027] The transmission component 27 includes a connecting block 271, which is bolted to the mounting plate 23 on the side closest to it. A movable block 272 is movably inserted into the side of the connecting block 271 furthest from the mounting plate 23. Connecting rods 273 are welded to the top and bottom of the movable block 272. Transmission plates 274 are bolted to both sides of the inner wall of the excavator bucket 11, and a transmission rod 275 is bolted to the rear side between opposite sides of the two transmission plates 274. The transmission plates 274 cooperate with the movable block 272. By setting up the transmission component 27, when the mounting plate 23 moves the movable block 272... When the moving block 272 and the connecting block 271 enter the interior of the transmission plate 274, the vibration generated by the eccentric block 265 will cause the connecting rod 273 on the moving block 272 to strike the transmission plate 274 and transmit the force to the transmission rod 275. The transmission rod 275 then disperses and transmits the force to other areas inside the digging bucket 11, driving the movement of materials in the surrounding area and deep inside the digging bucket 11. This allows materials in the depths and outside to be loosened simultaneously, achieving a wider soil loosening effect and allowing the materials inside the digging bucket 11 to be fully loosened, facilitating subsequent digging and unloading operations.

[0028] The connecting rod 273 has a semi-circular protrusion on the side away from the movable block 272, and the front side of the transmission plate 274 has a plug-in slot for use with the movable block 272. The semi-circular protrusion on the side of the connecting rod 273 away from the movable block 272 ensures that the direction of force transmission is accurate and avoids force transmission deviation or unstable connection. This improves the efficiency and accuracy of force transmission of the transmission component 27 and ensures the effective performance of the soil loosening function.

[0029] The mounting plate 23 consists of an upper support plate 4 and a lower support plate 5. A hydraulic rod 6 is rotatably connected between the opposite sides of the upper support plate 4 and the lower support plate 5. A support spring 7 is sleeved on the surface of the hydraulic rod 6. The support spring 7 is connected to the upper support plate 4 and the lower support plate 5 respectively. By setting the mounting plate 23 to consist of an upper support plate 4 and a lower support plate 5, and setting the hydraulic rod 6 and the support spring 7 between them, the vibration generated by the rotation of the hydraulic rod 6 and the support spring 7 can be blocked from being transmitted outward due to the rotation of the eccentric block 265. This can prevent impact on the connection between the mounting plate 23 and the external structure, ensuring the stability of the mounting plate 23 in use. It can also play a buffering role when encountering a large impact force (the reaction force when loosening hard materials), protecting the soil loosening structure 2 and the bucket structure 1 from damage.

[0030] A sealing plate 8 is bolted between the upper support plate 4 and the lower support plate 5 on opposite sides, and the sealing plate 8 is rectangularly positioned between them. Hydraulic rods 6 are evenly distributed between the upper support plate 4 and the lower support plate 5 on opposite sides. By setting the sealing plate 8, the upper support plate 4 and the lower support plate 5 can be sealed, reducing the impact of external factors on the operation of the hydraulic rods 6. The evenly distributed hydraulic rods 6 between the upper support plate 4 and the lower support plate 5 on opposite sides ensure that the mounting plate 23 can evenly transmit and distribute the force when subjected to external force, ensuring that the force on each part is balanced and avoiding damage to the components due to excessive local force.

[0031] The working principle of this embodiment is as follows: A hydraulic cylinder structure is externally connected to the bottom of the front side of the mounting plate 23, and the other end of the hydraulic cylinder structure is connected to the boom of the excavator. After the bucket structure 1 finishes digging material, the hydraulic cylinder structure externally connected to the mounting plate 23 pushes it to rotate around the rotating frame 21, so that the mounting plate 23 is close to the digging bucket 11. The externally connected hydraulic motor drives the main shaft 25 to rotate, and the main shaft 25 drives the first mounting sleeve 261 and the second mounting sleeve 262 sleeved on its surface to rotate accordingly. As the loosening teeth 263 rotate, they continuously cut into the material, crushing and loosening it. Simultaneously, the disturbance component 264 behind the second mounting sleeve 262 and the eccentric block 265 on the main shaft 25 function during rotation. The eccentric block 265 vibrates due to rotation, causing the disturbance component 264 to exert additional disturbance and squeezing forces on the material. The push block 264c inside the disturbance component 264 slides within the fixed cylinder 264a. When impacted by material, the push block 264c compresses the pressure spring 264d and squeezes the oil. The oil then passes through… The damping effect buffers the impact force, and then the elastic restoring force of the compression spring 264d pushes the push block 264c forward to reset. The oil also generates a certain resistance to the reset motion of the push block 264c, causing the push block 264c to reciprocate. This reciprocating motion transmits the force to the outside through the transmission rod 264b, further crushing and loosening the material. When the movable block 272 enters the transmission plate 274, the vibration generated by the eccentric block 265 is transmitted to the transmission plate 274 through the movable block 272 and the connecting rod 273, and the force is transferred to the transmission plate 274. The force is transmitted to the transmission rod 275, which then distributes the force to other areas inside the digging bucket 11, causing the surrounding materials to move and achieving a wider loosening effect. This allows the materials to be fully loosened within the digging bucket 11, facilitating subsequent digging and unloading operations. During the loosening process, the intensity and effect of loosening can be flexibly adjusted by adjusting the rotational speed of the main shaft 25, changing the distribution or number of the first mounting sleeve 261 and the second mounting sleeve 262, depending on the texture and hardness of the materials, to adapt to different operational needs.

[0032] Example 2 refer to Figure 8An excavator bucket capable of loosening material and soil also includes an extension assembly 15. The extension assembly 15 includes a connecting plate 151, which is bolted to the side of the excavator bucket 11 closest to it. A second hinge plate 152 is located at the bottom of the front side of the connecting plate 151, and a fixing plate 153 is located on the front side of the second hinge plate 152. Several secondary soil-breaking teeth 154 are bolted to the surface of the fixing plate 153, which is bolted to the side of the fixing plate 153 closest to the first hinge plate 13. A mounting base 155 is bolted to the front side of the connecting plate 151, and hydraulic cylinders 156 are rotatably connected to both sides inside the mounting base 155. The other end of each hydraulic cylinder 156 is rotatably connected to the fixing plate 153. By providing the extension assembly 15, the fixing plate 153 and the secondary soil-breaking teeth 154 thereon can be adjusted by controlling the extension and retraction of the hydraulic cylinders 156. The angle and position are adjusted to achieve the optimal soil-breaking posture. During excavation, the secondary soil-breaking tooth 154 cuts into the material together with the main soil-breaking tooth 14. As the excavator moves, the secondary soil-breaking tooth 154, supported and adjusted by the hydraulic cylinder 156, adjusts its angle and position in real time according to the resistance of the material, continuously breaking and excavating the material. It works in conjunction with the main soil-breaking tooth 14 to expand the soil-breaking range and depth, improving the overall excavation efficiency. On the one hand, it increases the number of soil-breaking teeth at the front end of the excavating bucket 11, expands the soil-breaking area, and improves the soil-breaking ability for soil layers of different hardness (especially hard soil layers), thus improving excavation efficiency. On the other hand, the adjustability of the hydraulic cylinder 156 allows the angle and position of the secondary soil-breaking tooth 154 to be flexibly changed according to the actual excavation situation, adapting to different working conditions and material states, enhancing the adaptability and flexibility of the bucket structure 1.

[0033] The connecting plate 151 is bolted to the front of a baffle 9. The bottom of the baffle 9 is provided with an elastic connecting part, which is connected to the fixed plate 153. By setting the baffle 9 and the elastic connecting part, the internal structure can be protected. When encountering irregular materials or different digging angles, the elastic connecting part can adaptively adjust the state of the fixed plate 153, absorb and buffer external forces in various directions, so that components such as the hydraulic cylinder 156 can always maintain a good working state and reduce the interference of external factors on the expansion component 15.

[0034] The working principle of this embodiment is as follows: The excavator controls the digging bucket 11 to move above the material pile. Based on the material accumulation and digging requirements, the position and angle of the digging bucket 11 are adjusted, and the excavator's digging action is initiated. The digging bucket 11 begins to descend under the drive of the digging arm. The main breaking teeth 14 and the auxiliary breaking teeth 154 first contact the material, relying on the excavator's power to cut into the material and perform soil breaking and digging. As the digging bucket 11 digs deeper, the auxiliary breaking teeth 154, supported and adjusted by the hydraulic cylinder 156, adjust their angle and position in real time according to the material resistance and other factors. The main breaking teeth 14 work together to excavate the material, expanding the breaking range and depth, and improving the overall excavation efficiency. The cooperation between the secondary breaking teeth 154 and the main breaking teeth 14 increases the number of breaking teeth at the front end of the excavating bucket 11, expands the breaking area, and improves the ability to break through soil layers of different hardness, thereby improving excavation efficiency. On the other hand, the adjustability of the hydraulic cylinder 156 allows the angle and position of the secondary breaking teeth 154 and the main breaking teeth 14 to be flexibly changed according to the actual excavation situation, adapting to different working conditions and material states, thus enhancing the adaptability and flexibility of the bucket structure 1.
