[0034] Working principle: When coring of a road is required, the operator first moves the coring machine to the coring point of the road, then starts the engine 22 and the reducer 23 to rotate the diamond drill bit 24, and manually rotates the rotating wheel 34 to rotate the lead screw 32, the lead screw 32 drives the lifting seat 31 to descend vertically, and the lifting seat 31 causes the coring unit 2 to descend as a whole; At the same time, the operator fills the drilling water into the water storage pan 51 through the water injection pipe 42, and turns on the motor 6. The drilling water in the water storage pan 51 flows to the conical surface of the conical ring 56 through the drainage pipe 53. The driving shaft of the motor 6 rotates the driving gear 66 through the rotating rod 61, the hollow sleeve 62, the first hexagonal seat 63, the second hexagonal seat 65 and the hollow rod 64. The driving gear 66 rotates the water storage pan 51 in the equipment sleeve 4 through the gear ring 67. The water storage pan 51 causes the drainage pipe 53 to revolve in a circle, and the drainage pipe 53 The other end of the drain pipe 53 revolves in a circle on the conical surface of the conical ring 56. The revolving circle of the drain pipe 53 makes the water used for drilling operations evenly distributed on the conical surface of the conical ring 56. The water used for drilling operations on the conical surface flows into the conical cavity 57 and is evenly distributed on the outer wall of the diamond drill bit 24 through a plurality of water nozzles 58 distributed in an annular array, thereby conveniently realizing automatic water addition during the coring operation of the road, thereby improving the coring efficiency and service life of the diamond drill bit 24, and replacing manual operation to reduce the coring operation intensity of the workers. When the diamond drill bit 24 finishes drilling and coring, the diamond drill bit 24 takes out the core sample as the diamond drill bit 24 rotates in the opposite direction and rises. At this time, the operator manually turns the knob 96, and the knob 96 rotates the threaded rod 95. The threaded rod 95 drives the slider 91 to slide vertically upward in the slide groove 94. The slider 91 makes the hollow sleeve 62 and the No. 1 hexagonal seat 63 rise vertically through the connecting rod 92 and the rotating sleeve 93. When the No. 1 hexagonal seat 63 is completely sleeved with the No. 3 hexagonal seat 83, the knob 96 is stopped from being turned. As the motor 6 continues to operate, the rotating rod 61 rotates the third transmission rod 82 through the hollow sleeve 62, the No. 1 hexagonal seat 63 and the No. 3 hexagonal seat 83, and the third transmission rod 82 rotates the first transmission rod 78 through the two second bevel gears 84. The first transmission rod 78 rotates the two second transmission rods 79 through the four first bevel gears 8, and the two second transmission rods 79 cause the two cams 81 to rotate synchronously in the same direction. The raised parts of the two cams 81 push the two connecting plates 74 to asynchronously flip upward in a staggered state. At the same time, the four torsion springs 76 are affected, and the resetting of the four torsion springs 76 causes the two connecting plates 74 and the two knocking balls 75 to flip in the opposite direction and reset through the two fixed sleeves 73. In this process, the two knocking balls 75 continuously knock on the diamond drill bit 24 in an asynchronous state, causing the core sample to fall downward and separate from the diamond drill bit 24, thereby conveniently realizing the automatic separation of the core sample from the diamond drill bit 24, avoiding manual removal of the core sample, improving the efficiency of road coring, and at the same time, further reducing the coring operation intensity of the workers.
