Digger with ranging system

The utility model relates to a digger with ranging system. This ranging system includes: electromagnetism output device (102) provide along first bundle route (106) electromagnetic radiation first bundle (104), first bundle reflection electromagnetic radiation (110) coming from object (7) are received in electromagnetism input device (108) to confirm distance (114) of ranging system (100) and object (7), and shell (120), include around lateral wall (122) of central axis (136) of shell (120). Electromagnetism output device (102) and electromagnetism input device (108) set up in shell (120) for electromagnetism input device (108) are located the second of electromagnetic radiation second bundle (126) and restraint route (124) outside, and the second is restrainted and is injectd by first bundle (104) specular reflection (128) on lateral wall (122). Digger (3) still have data port (40), its relative position data that arrive the object at least based on distance (114) the output diggers of confirming (3). 本实用新型涉
