the upper rod 31 transmits the impact action to the transmission inclined block 34 through the transmission slide block 32 and the transmission rod 35 connected with the transmission slide block 32, the transmission inclined block 34 transmits the impact action to the lower pipe 33, the lower pipe 33 transmits the impact action to the drill rod 9 through the middle rod 91, and the drill rod 9 moves a corresponding distance to the ground;
after the transmission plate 2, the upper rod 31, the lower tube 33 and the drill rod 9 synchronously move downwards, the transmission plate 2 is separated from the limiting block 38, when the heavy object 8 is stretched and lifted up again, the telescopic spring 37 pushes the transmission slide block 32 to drive the upper rod 31 to move upwards, at the moment, the transmission rod 35 firstly contracts to the transmission chute 321 and then extends out of the transmission chute 321 to a position between the two transmission inclined blocks 34 until the transmission plate 2 abuts against the limiting block 38 again, and therefore when the heavy object 8 is contacted with the transmission plate 2, the falling distance of the heavy object 8 is stable;
the weight 8 can apply an acting force to the drill rod 9 at a fixed height, generally 50 cm, without other acting forces, so that the accuracy of drill rod detection measurement is ensured.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
