Description

Technical Field

[0001] The utility model relates to the technical field of excavators, in particular to an excavator door device. Background Art

[0002] An excavator, also known as an excavating machine or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and load them into transport vehicles or unload them to a stockpile. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. This material is very easy to slip due to its looseness and collide with the excavator. The door panel of the excavator is the place where collisions are most likely to occur during the use of the excavator, affecting the driver's operating safety and the stability of the excavator during use; the upper half of the existing excavator door panel is generally equipped with a glass window, which has weak pressure resistance. If a pressure-resistant component is set at the glass window, it will affect the driver's line of sight and communication with the outside world, and it will also be impossible to pass items through the window, affecting the normal use of the window on the door panel.
