Rock sampling tool for a robot

Abstract

The application provides a rock sampling tool for a robot, and relates to a rock sampling device, which comprises a driving module, a connecting rod mechanism, a knocking module and a rock sample collecting module; the driving module comprises a motor; the output shaft of the motor is connected with a poking rod; the upper end of a first connecting rod is rotatably connected with the output shaft, and the lower end is rotatably connected with the upper end of a second connecting rod; the first connecting rod is provided with a contact rod; the knocking module comprises a striking rod which is slidably arranged in a guide sleeve; the upper end of the striking rod is rotatably connected with the lower end of the second connecting rod, and the lower end is provided with a striking head; the lower end of a first elastic member is connected with the striking rod, and the upper end is connected with the guide sleeve; and the rock sample collecting module comprises a net bag; the first connecting rod is rotated to the highest point under the pushing of the poking rod, and the first elastic member is compressed; then the poking rod is separated from the contact rod, and the first elastic member rebounds to drive the striking rod to move forward and out. The application has the beneficial effects that the energy is stored in the elastic member, the instantaneous high-power output can be realized, and the power consumption can be reduced during the energy storage and release interval.
