Milling and digging head mechanism and milling and digging machine
The invention provides a milling and digging head mechanism which comprises a mounting plate, a large arm, a connecting rod, a crank and a limiting plate, a milling and digging head is pivoted to the front end of the large arm, and the rear end of the large arm is pivoted to the mounting plate; the first end of the connecting rod is pivoted to the middle of the big arm, and the middle of the big arm is located between the front end and the rear end of the big arm. The first end of the crank is pivoted to the second end of the connecting rod, and the second end is pivoted to the mounting plate and connected with a motor; and the limiting plate is arranged above and/or below the large arm, one end of the limiting plate is fixedly arranged on the mounting plate, and a spring is arranged between the limiting plate and the large arm. According to the milling and digging head mechanism provided by the invention, the crank-link mechanism is arranged, so that the large arm vibrates at a certain frequency in the vertical direction, and then the milling and digging head is driven to swing at a certain frequency, high impact force is applied to rocks so as to crush the rocks, the abrasion damage to the milling and digging head is reduced, and the operation efficiency of the milling and digging head mechanism is improved; by arranging the spring, the large arm is driven to move in the direction close to the limiting plate, and certain buffering force is provided for the large arm.
本发明提供一种铣挖头机构，包括安装板、大臂、连杆、曲柄和限位板，大臂的前端枢接有铣挖头，后端枢接于安装板；连杆的第一端枢接于大臂的中部，大臂的中部介于大臂的前端和大臂的后端之间；曲柄的第一端枢接于连杆的第二端，第二端枢接于安装板且连接有电机；以及，限位板，其设于大臂的上方和/或下方且其一端固设于安装板，限位板和大臂之间设有弹簧。本发明提供的一种铣挖头机构，通过设置曲柄连杆机构，实现大臂沿竖直方向以一定频率振动，进而带动铣挖头以一定频率摆动，对岩石施加较高的冲击力以击碎岩石，减少对铣挖头的磨损破坏，提高铣挖头机构的作业效率；通过设置弹簧，驱动大臂沿靠近限位板的方向移动，为大臂提供一定的缓冲力。
