Description

Technical Field

[0001] The present application relates to the technical field of buckets, and particularly to a side-dumping bucket and an underground loader. Background Art

[0002] In the field of construction machinery, mining tunnel machinery occupies an important position. Among them, the underground loader, as a core equipment, with its efficient handling ability, effectively improves the mining efficiency, improves the working environment and reduces the mining cost, and is widely used in various mining and ore transportation construction scenarios. However, there are obvious problems with the existing buckets of the existing underground loaders in actual operation; the unloading method is single and lacks the ability of horizontal operation: the existing loaders can only unload vertically by tilting the bucket forward and do not have the function of horizontal unloading. In special scenarios such as narrow tunnels and near the rock wall, it is impossible to approach the target unloading point, and the equipment can only be repeatedly moved to adjust the position, which not only increases the equipment wear and energy consumption, but also greatly prolongs the single operation time and seriously affects the construction progress; therefore, the application of the traditional underground loader bucket faces many severe challenges. Due to the generally narrow and tortuous characteristics of the underground roadway space, the width of some roadway sections is even less than 3 meters, and coupled with the different specifications of transportation vehicles and the complex layout of the operation space, there are significant limitations in the unloading link of the traditional bucket. In the actual operation process, the operator often needs to spend a lot of time and energy adjusting the position of the loader to find a suitable unloading angle and space, which not only greatly reduces the unloading efficiency, and the single unloading time is nearly 2 - 3 times longer than the ideal working condition, but also significantly increases the manual operation intensity. In a special working environment with complex geological structures and large roadway slopes, the unloading difficulty of the traditional bucket increases exponentially, and it is extremely easy to cause safety hazards such as material spillage and equipment collision, which seriously restricts the efficient progress and safe production of underground mining operations. Summary of the Invention

[0018] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of this application and its application or use. Embodiment 1

[0019] As Figure 1 and Figure 2As shown in the figure, this embodiment discloses a side-dumping bucket, which includes a bucket body, a side-dumping device 5, and a driving member 7. One end of the bucket body 1 is rotatably installed on the side-dumping device 5, and a notch 100 is provided on one side of the bucket body 1 near the connection between the bucket body 1 and the side-dumping device 5. The bucket body 1 has a first position where the notch 100 is extremely inclined outward and a second position where it fits with the side-dumping device 5. Both ends of the driving member are movably connected to the bucket body 1 and the side-dumping device 5. In production, the side-dumping device 5 uses a large connecting rod as the main body, and mounting lugs are provided on the connecting rod, and the lugs can be used to install the boom of an engineering vehicle.

[0020] During use, the driving member 7 works to switch the bucket body 1 between the first position and the second position. In actual use, the bucket body 1 can perform a sector-shaped movement around the connection with the side-dumping device 5 to achieve the "opening and closing" movement between the bucket body and the side-dumping device 5. It should be noted here that the orientation of the notch 100 is the same as the movement direction of the bucket body to ensure the smooth external discharge of materials.

[0021] In some embodiments, the side-dumping bucket is designed as follows; As shown in the attached Figure 1 figure, a first limiting portion is provided between the side-dumping device 5 and the bucket body 1. The first limiting portion includes a first limiting plate 2 and a limiting mechanism 3. In this embodiment, the limiting mechanism 3 is actually a triangular block. The first limiting plate 2 is fixed on the bucket body 1, and the limiting mechanism 3 is fixed on the side-dumping device 5. When the bucket body is in the first position, the limiting mechanism and the first limiting plate 2 are in rigid contact. The driving member in this embodiment is a telescopic member, such as a cylinder, a hydraulic cylinder, an oil cylinder, etc. Here, an oil cylinder is used as the driving member 7. At this time, the design of the first limiting portion is to ensure the positioning of the bucket body 1 in the first position.

[0022] A second limiting portion is also designed in this embodiment, which is used when the bucket body 1 is in the first position. The second limiting portion includes a second limiting plate 4 and a positioning plate 200. The radian of the fitting surface of the positioning plate 200 and the second limiting plate 4 is the same (arc surface design) to ensure the accuracy of the position when the bucket body 1 retracts. As shown in the attached Figure 2 figure, multiple positioning plates 200 are provided, and the multiple positioning plates 200 are linearly fixed on the bucket body 1. It should also be mentioned here that the positioning plate 200 also functions as a wear-resistant plate to reduce unnecessary wear on the bucket body during long-term use of the equipment. The second limiting plate 4 is welded to the side-dumping device. Figure 1It is the initial state of the equipment. In the non-operating condition, the driving part 7 is in a fully contracted state, and the entire side-dumping bucket device is in the standby ready mode. The core components of the device include a side-dumping bucket 1, a first limit plate 2, a limit mechanism 3, and a second limit plate 4. Among them, the side-dumping bucket 1 and the second limit plate 4 are closely attached through a precise structural design. This attachment state not only ensures the structural stability of the equipment during idle periods, effectively avoiding accidental displacement caused by external force collisions, but also provides an accurate initial position reference for subsequent operations. Through their interaction, the tilting angle of the side-tilting bucket 1 can be strictly controlled within a safe and efficient range, effectively avoiding material spillage or damage to the equipment structure caused by excessive tilting.

[0023] As shown in the Figure 4 attachment, when the side-dumping bucket 1 performs the unloading operation and reaches the optimal tilting angle of 45°, which is obtained through a large number of simulation practices and data demonstrations, the first limit plate 2 and the limit mechanism 3 form a rigid abutment. This limit design is based on the principle of mechanical mechanics. Through the interaction between the limit plate and the limit mechanism, on the one hand, it can ensure that the bucket maintains a stable tilting posture during the unloading process, ensuring that the material can be unloaded smoothly and efficiently; on the other hand, through mechanical limiting, it effectively shares the pressure borne by the driving part 7, reduces its load under extreme working conditions, thereby significantly extending the service life of the oil cylinder and reducing the equipment maintenance cost. At the same time, the unloading side of the side-dumping bucket 1 is specially designed with a side-unloading inclination angle of 109°, which perfectly matches the 45° inclination angle of the bucket body 1 itself. This unique dual-angle design enables the side-dumping bucket to make full use of gravity and mechanical principles during the unloading process to achieve complete side unloading of the material. Even when facing highly viscous and easily adherent materials, it can ensure clean unloading without residue.

[0024] As shown in the Figure 2 attachment Figure 3As shown in the figure, the dynamic process of the side-dumping bucket 1 during side-dumping operation is presented. The side-dumping bucket 1 system demonstrates a precise mechanical transmission and cooperative working mechanism. Its core structure includes a side-inclination device 5, a lower hinge pin shaft 6, a driving member 7 (oil cylinder), an upper hinge pin shaft 8. One end of the driving member 7 is hinged to the bucket body 1 through the upper hinge pin shaft 8, and this connection point is the first connection point. The other end is hinged to the side-dumping device 5 through the lower hinge pin 6, and this connection point is the second connection point. The first connection point is arranged closer to the notch 100 relative to the second connection point. When the hydraulic system delivers high-pressure hydraulic fluid to the driving member 7, the driving member 7 starts to work as a power source, and the extension action of the piston rod generates a strong thrust. During this process, the lower hinge pin shaft 6 and the upper hinge pin shaft 8, as key force transmission and motion conversion components, form a high-precision rotating kinematic pair after bearing the shear force generated by the oil cylinder thrust. Under the continuous thrust of the driving member 7, the bucket body 1 rotates clockwise or counterclockwise with the side-dumping pin shaft 9 as the rotation fulcrum. As the bucket body 1 rotates, the first limit plate 2 gradually approaches the limit mechanism 3 until they collide and contact. This collision moment indicates that the side-dumping bucket 1 has reached the optimal discharge angle, at which time the material can be discharged at the fastest speed and with the highest efficiency under the action of gravity. After the discharging is completed, the hydraulic system changes the oil flow direction, and the driving member 7 enters the retracting mode. Relying on the reverse pressure of the hydraulic oil, the piston rod drives the side-dumping bucket 1 to return to its original position smoothly.

[0025] As shown in the appendix Figure 3 and Figure 4 shown, when the work stops after the side-dumping bucket 1 returns to its original position, relying on the connection strength of the driving member 7 itself to support the side-dumping bucket 1 for a long time will accelerate the wear of the driving member 7. In a further embodiment at this time, a locking assembly 10 is used to solve this problem. The locking assembly 10 includes a locking member 102 and a fixed seat 101. The locking member 102 is movably inserted through the fixed seat 101. There is a locking hole on the side-dumping device 5. When the side-dumping bucket 1 is in the second position, the locking member 102 is moved into the locking hole. Usually, a threaded through-hole is provided in the fixed seat 101, and a bolt is used as the locking member 102. The locking member 102 and the fixed seat 101 are in threaded cooperation. By rotating the locking member 102, it is moved in and out of the locking hole to achieve the locking and unlocking actions. Through precise limit control, it is ensured that the side-dumping bucket 1 accurately returns to its original working state and completes the action of closing the bucket. The entire operation process includes multiple links such as power transmission, mechanical rotation, angle limitation, material unloading, and equipment reset. Each component is closely linked and cooperates with each other to form a set of efficient, stable, and safe automated unloading system, effectively solving problems such as low discharge efficiency and complex operation of traditional buckets, providing strong technical support for underground mining operations, and reducing the work difficulty of the staff.

The boom of the underground loader and the side-dumping device 5 are connected by a rotating shaft, and the hydraulic rod on the underground loader is rotatably connected to the middle of the side-dumping device 5.
