The 1 inside other end of cabinet of 11 top of test chamber is provided with drilling compensated cavity 22, and 22 left side of compensated cavity that drills The second left sliding rail 23 is welded on 1 inner wall of cabinet, the left side of drilling compensated cavity 22 is symmetrically welded with the second fixed block 24, and second The bottom end of fixed block 24 is all symmetrically arranged with and the second mutually matched second pulley 25 of left sliding rail 23, the top of the second fixed block 24 End is all symmetrically fixed with the second limited block 26, and the top of belt 10 is fixed with to be connect with the second limited block 26 mutually matched second Block 27, the center position inside drilling compensated cavity 22 offer drilling auxiliary through hole 28, and the length of test chamber 11, which is equal to, to drill The length of compensated cavity 22, the width of test chamber 11 are equal to the width of drilling compensated cavity 22, the central axis for the auxiliary through hole 28 that drills It is overlapped respectively with the central axis of the central axis of drilling compensated cavity 22, test chamber 11 with the central axis of probe 5, effect is So that the area equation of test chamber 11 and drilling compensated cavity 22, and guarantee that probe 5 can steadily be fallen into inside drilling 3, It is welded with the second right sliding rail 29 on 1 inner wall of cabinet on drilling compensated cavity 22 right side, the right side of drilling compensated cavity 22 is fixed with and the Two mutually matched second sliding blocks 30 of right sliding rail 29.

Embodiment 2, as shown in Fig. 1,2,3,4,6 and 7, by first rotating shaft 6, driving wheel 7, the second shaft 8, driven wheel 9, Belt 10, test chamber 11, the first left sliding rail 12, the first fixed block 13, first pulley 14, the first limited block 15, the first link block 16, the first right sliding rail 20, the first sliding block 21, drilling compensated cavity 22, the second left sliding rail 23, the second fixed block 24, second pulley 25, Second limited block 26, the second link block 27, the second right sliding rail 29 and the second sliding block 30 form location structure, using novel pair Chamber cross structure, solve traditional such device need testing staff ceaselessly move whole device carry out correction positioning make to visit The problem of first 5 surface in drilling 3, time saving and energy saving, the time before reducing detection, so as to shorten detection time, Detection efficiency is improved, and alleviates the work difficulty of testing staff.

Working principle: in use, device is moved to designated position first, the inserted link on snap ring is then extracted, by suitable Hour hands shake first rotating shaft 6, so that first rotating shaft 6 drives driving wheel 7 to rotate, and drive the second shaft under the action of belt 10 8 and driven wheel 9 rotate with it, at this time in the second link block 27 and the second limited block 26, the first limited block 15 and the first link block So that test chamber 11 is moved to the left under 16 interaction, drilling compensated cavity 22 moves right, in the process, 11 meeting of test chamber Under the interaction of the first left sliding rail 12, the first fixed block 13, first pulley 14, the first right sliding rail 20 and the first sliding block 21 Stable sliding, is not in the unstable situation of sliding, and drilling compensated cavity 22 can be in the second left sliding rail 23, the second fixed block 24, the Stable sliding under the interaction of two pulleys 25, the second right sliding rail 29 and the second sliding block 30 is equally not in that sliding is unstable Situation, when the compensated cavity 22 that drills is mobile can not move with the attaching of 1 inner wall of cabinet, the first rotating shaft that stops operating 6, again by inserted link It injects in snap ring, drilling machine can be utilized at this time, brill is dynamic downwards through drilling auxiliary through hole 28 by drill bit, is drilled the drilling 3 of 30cm Afterwards, drilling machine is taken out from drilling auxiliary through hole 28, then extract the inserted link on snap ring and rotates counterclockwise first rotating shaft 6, so that Test chamber 11 and drilling compensated cavity 22 return to home position, then again inject inserted link in snap ring, can be carried out power at this time Penetration tests are solved traditional such device and testing staff are needed ceaselessly to move using novel two-chamber cross structure Whole device carries out the problem of surface that correction positioning makes probe 5 in drilling 3, time saving and energy saving, the standard before reducing detection The standby time improves detection efficiency so as to shorten detection time, and alleviates the work difficulty of testing staff；

When carrying out dynamic sounding detection, by extracting the inserted link on snap ring, release third shaft 17 at this time can be in probe 5 Gravity under so that probe 5 does the movement of falling object, until probe 5 is contacted with 3 bottom surfaces that drill, squeeze into soil layer, every time Soil layer 30cm is squeezed into, injection blow counts N10 is recorded, if N10 is more than belt 100 or injection 10cm blow counts are more than 50, is stopped Injection after probe 5 makees a freely falling body, needs to rotate third shaft 17 in the process, hangs so that third shaft 17 drives 19 rotation of rope, and the drive of probe 5 is moved up, rapider due to rotating, probe 5 can shake, and keep out chamber when moving on on probe 5 When 4 position, probe 5 can just limit by keeping out four walls of chamber 4, be reached inside gear chamber 4 so that probe 5 moves up, at this time If ramping up again, then the top of probe 5 will strike the rubber pad 34 of 33 inside of rotating plate, so that rotating plate 33 is hinged first It is tilted upwards under the action of axis 32, so that driving wraping plate 36 to hit upwards agitates strut 38, in the hinged work of the second articulated shaft 37 Make the inner opposite end for agitating strut 38 can downwards with lower, link 31 will stick into the groove on link arrival slot 39 at this time, this When people will may feel that downward power stops probe 5 to continue to move up when rotating third shaft 17, can stop at this time Third shaft 17 is rotated, the movement of falling object next time is then carried out, then repeatedly aforesaid operations, solves detection people Member needs slowly rotation third shaft 17 and slowly increase probe 5, avoids the problem that next its wobble effects device detects, Shorten upwards receive probe 5 time, and receive probe 5 finally, ensure that probe 5 stabilization, will not shake, thus side Just the progress quickly detected next time, the time needed for shortening entire detection, and alleviate the work of testing staff Difficulty and pressure, improve the practicability of device, and operation leaves it at that.

It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
