The invention discloses an excavating device. The excavating device comprises a revolving mechanism, a main arm, a bucket arm and an excavating and grasping mechanism; an amplitude changing device isarranged between the main arm and the bucket arm; the amplitude changing device comprises a fixed connecting rod, a driving connecting rod, a revolving connecting rod and a rotating connecting rod; the fixed connecting rod is connected with the main arm; the revolving connecting rod is rotatably connected with the driving connecting rod; the rotating connecting rod is rotatably connected with themain arm; the driving connecting rod is rotatably connected with the fixed connecting rod; the rotating connecting rod is rotatably connected with the bucket arm; and the driving connecting rod extends and retracts to drive the revolving connecting rod to move. The invention further comprises a mobile machinery shop. According to the excavating device and the mobile machinery shop disclosed by theinvention, a six-connecting rod mechanism is formed by the main arm, the fixed connecting rod, the driving connecting rod, the revolving connecting rod, the rotating connecting rod and the arm bucketwhich are connected rotatably; the amplitude change angle of the main arm and the bucket arm is increased; the operation depth is improved; the amplitude change angle is enlarged through the main armand the bucket arm; the height is reduced by folding the main bucket and the bucket arm; the height of the overall mobile machinery shop is reduced; and the transportability and driving passing capacity are met.
本发明公开了一种挖掘装置,该挖掘装置包括转动连接的回转机构、主臂、斗臂以及抓挖机构,主臂和斗臂之间设置变幅机构,变幅机构包括固定连杆、驱动连杆、回转连杆以及旋转连杆,固定连杆连接主臂,回转连杆与驱动连杆、旋转连以及主臂转动连接,驱动连杆与固定连杆转动连接,旋转连杆与斗臂转动连接,驱动连杆伸缩用于驱动回转连杆运动。本发明还公开了一种工程车。本发明公开的挖掘装置及工程车通过转动连接的主臂、固定连杆、驱动连杆、回转连杆、旋转连杆以及斗臂形成六连杆机构,增加了主臂和斗臂的变幅角度,提高了作业深度;通过主臂和斗臂扩大变幅角度,收拢降低了高度,降低了整车高度,满足运输性和行驶通过性。
