working principle:

When the tractor drilling device is in working condition, the tractor drives the whole drilling device to stop at the proper position to be drilled, the tractor drives the gearbox shaft 10 to rotate through the hydraulic device, and the rotation of the gearbox shaft 10 drives the movable connection on the gearbox shaft 10 The gear one 19 on the top rotates, the rotation of the gear one 19 makes the gear two 20 meshed with the gear one 19 rotate, and then drives the gearbox long axis 11 which is movably connected with the gear two 20 to rotate together, and the rotation of the gear box long axis 11 , drive the pulley one 16 that is movably connected together to rotate, and then make the pulley two 18 that is connected with the pulley one 16 through a belt rotate, and the rotation of the pulley two 18 drives the short shaft one 13 that is movably connected with it to rotate together, and then Drive the rotation of the gear three 21 that is movably connected with the short shaft one 13 and the rotation of the drill bit one 27, the gear four 22 meshes with the gear three 21, and the gear three 21 rotates, then drives the gear four 22 to rotate, because the gear four 22 is movably connected in the horizontal On the shaft 12, the horizontal shaft 12 also begins to rotate. The five gears 23 and the six gears 24 are movably connected on the horizontal shaft 12 in a movable connection mode. The rotation of the horizontal shaft 12 drives the five gears 23 and the six gears 24 to rotate, and the seven gears 25 Mesh with gear five 23, gear eight 26 mesh with gear six 24, the rotation of gear five 23 and gear six 24 drives the rotation of gear seven 25 and gear eight 26, gear seven 25 is movably connected with short shaft two 14, gear eight 26 It is movably connected with short shaft three 15, then gear seven 25 and gear eight 26 drive short shaft two 14 and short shaft three 15 to rotate, drill bit two 28 is fixedly connected with short shaft two 14, drill bit three 29 is fixedly connected with short shaft three 15, Then the short axis 2 14 and the short axis 3 15 drive the drill bit 2 28 and the drill bit 3 29 to rotate, so far the three drill bits all rotate, after the three drill bits rotate, the tractor provides power for the hydraulic cylinder, pushing the piston of the hydraulic cylinder from the start Since the piston of the hydraulic cylinder is movably connected to the lifting bracket 3 of the lifting device, and the lifting device is movably connected to the fixing device through the slider 4, the whole lifting device moves downward together with the piston, and the drill bit rotates downward. When the movement distance of the piston of the hydraulic cylinder reaches the stroke of the hydraulic cylinder, the downward movement stops. At this time, the tractor provides power to make the piston of the hydraulic cylinder move upward, and the three drill bits still keep rotating, and the whole action becomes the drill bit rotating upward. When the piston of the hydraulic cylinder rises to the initial position, the tractor stops supplying power to the hydraulic cylinder and the gearbox shaft 10, the upward movement stops, the rotation of the three drill bits stops, the entire drilling device stops, and the tractor drives the entire drill Hole device advances, and continues to stop when reaching suitable position, and tractor provides power for drilling device again, and drilling device repeats above-mentioned action, and Here it is the motion process of whole tractor drilling device.
