Description

Technical Field

[0001] This utility model relates to the field of open-pit mining equipment technology, and in particular to a high-efficiency shovel loading device for open-pit mining. Background Technology

[0002] In open-pit mining operations, the efficiency and adaptability of loading devices directly impact mining productivity and costs. Traditional loading devices have fixed bucket capacities, making it difficult to cope with changes in material characteristics (such as block size, moisture content, and loading requirements) under different working conditions. For example, excavating hard rock requires low-capacity, high-load operation, while handling loose materials requires high-capacity, rapid loading. Frequent changes to different bucket sizes lead to long downtime and low operational efficiency. Furthermore, the transmission components of existing devices (such as connecting rods and lead screws) are prone to wear in high-dust, high-impact environments, resulting in decreased component precision and even equipment failure. Insufficient dustproof design allows mining dust to easily penetrate the transmission system (such as the double-acting lead screw and internal threaded sleeve), exacerbating mechanical wear and shortening equipment lifespan. Simultaneously, the cutting edge design of traditional buckets has limited adaptability to complex geological conditions, making it difficult to further improve material stripping efficiency.

[0003] In the existing technology, although some adjustable buckets have capacity adjustment functions, they mostly adopt complex mechanical structures, resulting in high manufacturing costs and difficult maintenance. The wear resistance and dustproof performance of transmission components still need to be optimized, especially in long-term high-intensity operations, where precise coordination and stability issues are prominent.

[0004] Therefore, there is an urgent need for a high-efficiency loading device that can flexibly adjust the bucket capacity, improve the wear resistance and dustproof performance of the transmission components, and adapt to complex geological conditions, so as to meet the higher requirements for equipment flexibility, reliability and operation efficiency in open-pit mining scenarios.

The support arm 2 is hinged on the hinge seat 21, the hydraulic cylinder 3 is hinged on the support arm 2, and the telescopic end of the hydraulic cylinder 3 is hinged on the hinge seat 31.

[0038] Mounting shell 4 is fixedly installed on the top side of the middle part 11 of the bucket and located between hinge seat 1 21 and hinge seat 2 31, which can reduce the probability of collision that may occur during actual application.

[0039] Fixed blocks 421 are fixedly installed on both the front part 13 and the rear part 12 of the bucket. An inner threaded sleeve 42 is fixedly installed on both fixed blocks 421. A double-acting screw 41 is rotatably installed on the mounting shell 4. The two ends of the double-acting screw 41 are respectively threaded into the corresponding inner threaded sleeves 42. When the double-acting screw 41 rotates, it can control the front part 13 and the rear part 12 of the bucket to move in opposite directions, thereby enabling the adjustment of the capacity and coverage width of the bucket body 1. A drive motor 412 is fixedly installed on the middle part 11 of the bucket inside the mounting shell 4.

The content protected by this application does not involve improvements to software, circuits, and methods.

[0044] Working principle: In use, first connect and install the support arm 2 with the relevant machinery (such as an excavator), and then start the drive motor 41 according to the actual work needs. The drive motor 41 drives the double-acting screw 41 to rotate through the meshing transmission of the drive gear 413 and the driven gear 411. The rotation of the double-acting screw 41 causes the two inner threaded sleeves 42 to move in opposite directions, thereby driving the front part 13 and the rear part 12 of the bucket to expand outward or contract inward synchronously, thus adjusting the capacity and width of the device. During the adjustment process, connecting rod 121 and connecting rod 13... 1. The buckets slide within guide holes 122 and 132 respectively, ensuring that the front part 13 and the rear part 12 of the bucket remain stable during movement. When the bucket capacity is adjusted to the appropriate position, the hydraulic cylinder 3 pushes the support arm 2 to perform the loading operation. The bucket teeth 101 and the cutting edge work together to effectively improve the material stripping efficiency. In addition, the flexible dust cover 422 remains sealed during the extension and retraction of the bidirectional screw 41 to prevent dust from entering and affecting the transmission accuracy. The entire device achieves stepless adjustment of the bucket capacity through modular design, which significantly improves the adaptability of operation under different working conditions.
