[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, when a relatively large stone splashes and impacts the double-layer tempered glass plate, the double-layer tempered glass plate pushes the damping rod, and at the same time, the double-layer tempered glass plate pushes the connecting rod, and the connecting rod pushes the movable block to slide on the periphery of the sliding rod, and at the same time, the movable block compresses the spring 1, and the spring 1 generates elastic force, so that when a relatively large stone splashes and impacts the double-layer tempered glass plate, the impact force of the stone can be buffered, so that the double-layer tempered glass plate can withstand greater impact force and have a stronger protective effect.

[0023] 2. In the utility model, when the fan draws outside air into the cab, it blocks the outside dust through the filter plate. When the filter plate needs to be replaced and cleaned, the pull block is pulled, and the pull block drives the latch to slide out from the inside of the filter plate, and at the same time drives the sliding block to slide inside the shell, compressing spring 2, which generates elastic force. During installation, the pull block is pulled to slide the filter plate into the installation frame, and then the pull block is released. Spring 2 pushes the sliding block, and the sliding block drives the latch to insert into the inside of the filter plate, thereby realizing the ability to disassemble and clean the filter plate, preventing excessive dust from adhering to the filter plate, resulting in a decrease in the filtering effect of the filter plate.
