[0037] Specifically, in a specific embodiment of this utility model, the hopper 4 is specifically mounted on the toothed plate telescopic beam mechanism 3 via a hopper support device 10.
[0038] Specifically, in a specific embodiment of this utility model, the bearing housing assembly 5 is mounted on the gantry 1 via a bracket structure 9.
[0039] Specifically, in a specific embodiment of this utility model, the drive mechanism 8 is a three-in-one reducer.

[0041] In addition, this utility model embodiment also provides a crane, including the bucket telescopic system with bucket gate as described above, which also has the above-mentioned technical effects.
[0042] More specifically, gantry cranes with buckets are one of the lifting equipment used in port terminals for loading and unloading bulk cargo. They primarily unload through buckets. During bucket operation, the buckets need to be moved forward and backward via a telescopic system, typically using wire rope traction. Wire rope traction is cumbersome to maintain and leads to poor bucket stability during operation. Based on these technical problems, this utility model provides a bucket telescopic system for gantry cranes that solves the problems of cumbersome maintenance and bucket movement during operation. Specifically, it is a gear-driven bucket telescopic system, which has the advantages of simple structure and convenient maintenance. The core technical features include a telescopic beam, gantry frame, drive mechanism, double-wheel support device, bucket, bucket support, and single-wheel support device. The telescopic beam includes a main beam, crossbeam, toothed plates, and rails. Each of the two main beams has a toothed plate at a suitable position on its top and a rail at a suitable position on its bottom. The main beams are connected by crossbeams and can be disconnected at suitable positions using bolts for easy installation. The drive unit mainly consists of a three-in-one geared motor, bearing housing assembly, gear, shaft, lock nut, and spacer. The gear is installed in the middle of the shaft, with bearing housing assemblies on both sides. The bearings in the bearing housing assemblies are fixed by lock nuts and spacers. One end of the shaft is connected to the three-in-one geared motor. The telescopic beam is placed on the gantry frame via a support wheel assembly. The wheels on the support wheel assembly contact the rails on the telescopic beam. The support wheel assembly is welded to the gantry beam. The gear in the drive unit meshes with the toothed plate on the telescopic beam. The drive unit is connected to the bracket on the gantry frame via a support. The hopper is welded to the telescopic beam via a hopper support. The drive mechanism drives the gear to move the telescopic beam, thereby moving the hopper. The use of a gear and toothed plate reduces maintenance costs and alleviates the movement of the hopper during crane operation.In summary, traditional hopper telescopic systems in existing technologies are prone to wear, loosening, and unstable hopper movement under prolonged operation or heavy loads. In this solution, the gantry and bearing housing assembly serve as the system's supporting structure, providing a stable mounting base for other components. The gear shaft, hopper gear, and toothed plate telescopic beam mechanism together constitute the transmission system, achieving precise hopper movement. Improvements to the gear-toothed plate transmission method enhance system stability, reduce maintenance costs, and improve overall performance. Specifically, this solution achieves higher transmission accuracy and stability through the contact meshing of the hopper gear with the toothed plate on the toothed plate telescopic beam mechanism, significantly reducing improper movement during hopper operation. This method features self-locking, maintaining the relative stability of the hopper position even under heavy loads or sudden shutdowns, preventing material spillage or equipment damage. The stable transmission method allows the hopper to reach the designated position more accurately, improving operational efficiency. Furthermore, the gear-plate transmission method has a longer service life and lower wear rate compared to other transmission methods, reducing the frequency of replacement and maintenance, and making it easier to inspect and repair, thus lowering maintenance costs. Compared to existing technologies, the hopper telescopic system for a gate machine provided in this embodiment achieves stable operation and efficient operation of the hopper telescopic system through improvements to the gear-plate transmission method, while simultaneously reducing maintenance costs, demonstrating significant technical effects and application value.
