Excavator boom and excavator
The invention relates to the field of engineering machinery, in particular to an excavator boom and an excavator. The excavator boom comprises a front arm body, a rear arm body and a guide rail, the outer surface of the front arm body is connected with the outer surface of the rear arm body through the guide rail, and/or a cavity is formed in the front arm body; the tail portion of the front arm body is provided with an open hole communicated with the cavity in the front arm body, the guide rail is arranged in the cavity in the front arm body, the front end of the rear arm is inserted into the cavity in the front arm body through the open hole at the tail portion of the front arm body, the front arm body is connected with the rear arm through the guide rail, and a telescopic cylinder is further included; and one end of the telescopic cylinder is connected with the front arm body, and the other end of the telescopic cylinder is connected with the rear arm body. According to the excavator boom and the excavator, energy is saved, adjustment is convenient, the structure is reasonable, the manufacturing cost is low, safety is high, and implementation is easy.
本发明涉及工程机械领域，具体而言，涉及一种挖掘机动臂及挖掘机，包括前臂体，还包括后臂体和导轨，所述前臂体的外表面通过所述导轨与所述后臂体外表面连接，和/或所述前臂体的内部设有空腔，所述前臂体的尾部设置连通所述前臂体内部空腔的开孔，所述前臂体的内部空腔设置有所述导轨，所述后臂的前端由所述前臂体的尾部开孔插入所述前臂体的内部空腔，所述前臂体通过所述导轨与所述后臂连接，还包括伸缩缸，所述伸缩缸一端连接所述前臂体，所述伸缩缸另一端连接所述后臂体。本发明提供的挖掘机动臂及挖掘机，节能又便于调整，并且结构合理、制造成本低、安全性高、易于实施。
