Description

Technical Field

[0001] The utility model relates to the technical field of boom protection, in particular to a boom protection device for an excavator. Background Art

[0002] An excavator, also known as an excavating machine or backhoe, is an earth-moving machine that uses a bucket to excavate material above or below the surface and load it onto a transport vehicle or unload it into a stockpile. Excavators primarily excavate soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has seen relatively rapid growth, making them one of the most important types of machinery in construction. The three most important parameters for an excavator are operating weight, engine power, and bucket capacity. Boom: Backhoes generally have a curved boom, allowing them to effectively excavate below the surface. Face shovels, on the other hand, are typically straight, allowing them to better excavate above the surface. The upper and lower panels are the cover plates, the side panels are the wall panels, the boom mount is where the camera frame connects, the boom cylinder rod is connected to the boom middle sleeve, the middle cylinder lug is where it connects to the middle cylinder, and the boom clip is where it connects to the forearm.

[0003] Excavators currently operate in harsh environments and are widely used for foundation excavation and post-construction cleanup, demolition, earthwork, and mining. Due to varying construction schedules, lighting equipment is often used for nighttime operations to facilitate operation. Lights are often mounted on the boom to provide better visibility. Furthermore, the harsh working environment of excavators can lead to lamp failures, significantly reducing the lifespan of work lights. Traditional lamp protection devices often utilize a single-layer plastic casing and wire mesh, a combination that has a short lifespan and a high failure rate, making them inadequate for current protection needs.

[0004] To this end, we propose an excavator boom protection device. Utility Model Content
