Description

Technical Field

[0001] The invention relates to the technical field of mining vehicle cabs, in particular to a vibration-damping and impact-resistant mining vehicle cab. Background Art

[0002] The cab of a mining vehicle is a dedicated space in the mining industry that provides operation, control and protection for the driver. It is usually used in various types of mining transportation vehicles, such as mining trucks, loaders, mine cars, bulldozers, etc. The cab of a mining vehicle must have sufficient impact and compression strength to prevent damage to the driver in harsh mining environments, especially in accidents during underground operations.

[0003] The cab of a mining vehicle is not only a place where the driver operates the mining vehicle, but also an integrated body of complex safety protection and comfort design. It must meet the requirements of protection function, comfort, visibility, intelligent control, safety and other aspects to ensure that the driver can complete the work efficiently and safely in the complex and harsh mining environment.

[0004] When existing mining shovels are shoveling or loading ore, there is a risk of ore falling when the bucket is raised. The front side of the existing mining shovel cab lacks the function of blocking the falling ore, resulting in the falling ore possibly damaging the front windshield or other parts, which may cause a safety hazard to the driver, and at the same time will lead to an increase in equipment maintenance costs and reduce work efficiency.

[0005] In summary, the prior art lacks technology for protecting the mining shovel from ore falling from the bucket. Summary of the invention

The ore baffle not only blocks the falling ore, but also reduces the intensity of the ore hitting the shovel cab or equipment through the buffering effect, reduces the risk of equipment damage, and improves the working efficiency;

[0018] 2. By setting up an ore pushing mechanism, when the baffle frame rotates upward to reset, the stones that fall on the baffle frame and the ore baffle plate will be automatically pushed down, ensuring that after each operation, no ore will accumulate on the baffle frame and ore baffle plate of the shovel, avoiding the extra burden of ore on the equipment, reducing the need for manual cleaning, and reducing the risk of equipment damage and failure, thereby improving the safety, efficiency and reliability of mining shovels;

[0019] 3. By setting up a driving mechanism, the bucket arm can drive the bucket to be lifted up and at the same time drive the automatic retraction and extension of the baffle frame, so that the automatic operation of the bucket and the baffle frame can be realized without manual control, avoiding safety hazards caused by forgotten operations, greatly improving the working efficiency and operating accuracy of construction machinery. At the same time, by setting up a guardrail, the stones that fall onto the ore baffle can be blocked to prevent the stones from flying to other locations and causing safety hazards, further improving the safety of the shovel when in use.
