Description
Technical Field
[0001] The utility model relates to the technical field of hopper edge protection components, in particular to a protective enclosure structure for protecting the edge of a mining machinery hopper. Background Art
[0002] In mining and mineral processing, buckets are key equipment for shoveling materials. Their performance and durability have a direct impact on production efficiency and costs. The bucket teeth on the edge of the bucket not only need to withstand strong impact and wear from the materials, but also need to maintain structural integrity and stability in harsh working environments. Therefore, the design of the bucket tooth guard is particularly important, which is directly related to the bucket's service life, maintenance costs and production safety.
[0003] Traditional bucket tooth guards often use side pins for fixing. While this design achieves a certain degree of guard fixation and installation, it faces numerous challenges in practical application. The relatively narrow space between the teeth and the often dusty and debris-filled working environment significantly restrict the operating space for maintenance personnel. This makes it extremely difficult to remove and install the pins when replacing the guard or performing routine maintenance. This not only increases repair time but can also lead to human error during maintenance, thus impacting production schedules. Therefore, we have addressed this issue by proposing a guard structure for protecting the edge of mining machinery buckets. Summary of the Invention
[0004] The purpose of the utility model is to address the problem that the existing bucket tooth guards are mostly fixed by side pins. Since the space between the bucket teeth is relatively small and the working environment is often covered with dust and debris, this greatly limits the operating space for maintenance personnel.

Although this design achieves the fixation and installation of the guard to a certain extent, it faces many challenges in actual application. Since the space between the bucket teeth is relatively small and the working environment is often covered with dust and debris, this greatly limits the operating space of maintenance personnel, making it extremely difficult to disassemble and assemble the pins when replacing the guard or performing daily maintenance. This not only increases maintenance time, but may also lead to human errors during the maintenance process, thereby affecting production progress.
[0033] In order to solve this technical problem, the utility model provides a guard structure for protecting the edge of a mining machinery hopper.
[0034] Specifically, please refer to Figures 1-8 The protective enclosure structure for the edge protection of mining machinery hoppers specifically includes:
