Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 4.

As shown in fig. 1 to 4, the rammed earth sampling tool comprises a cylinder body 1, wherein a spiral head 2 is arranged at the bottom of the cylinder body 1, a first handrail 3 is arranged at the upper end of the cylinder body 1, a sampling cylinder 4 is sleeved in the cylinder body 1, the sampling cylinder 4 and the cylinder body 1 can rotate and can relatively slide, a plurality of groups of sampling ports 5 are arranged outside the cylinder body 1, a sampling cavity 6 corresponding to the sampling ports 5 is arranged on the sampling cylinder 4, a baffle 7 located at the sampling ports 5 is arranged on the cylinder body 1 in a rotating manner, and the sampling cylinder 4 pushes the baffle 7 to rotate to open or close the sampling ports 5 after rotating.

When taking a sample to rammed earth, rotate sampling tube 4 earlier, make baffle 7 close sample connection 5, then rotate barrel 1 through first handrail 3 downwards hard, the rammed earth is crowded to be opened by spiral head 2, squeeze into rammed earth with barrel 1, then rotate sampling tube 4, make baffle 7 open sample connection 5, reverse rotation barrel 1 this moment, the rammed earth that is located sample connection 5 position enters into barrel 1 inside from sample connection 5, be collected in sample chamber 6, then take out barrel 1 from the rammed earth, sample connection 4 and barrel 1 separation outside, obtain the outfit for a journey body sample of acquireing.

The sampling ports 5 are provided with a plurality of groups, are respectively positioned at different height positions of the cylinder body 1, and can directly obtain the depth position of the rammed soil sample at the moment according to the depth of the rammed soil.

When the rammed earth is driven into the rammed earth, the sampling port 5 is closed, and the sampling port 5 is opened again during sampling, so that the rammed earth sample in the sampling cavity 6 is not mixed with rammed earth with other depths, and the detection accuracy can be improved.

In order to take out the sampling tube 4,

first handrail

3 and 1 threaded connection of barrel, first handrail 3 is passed and is equipped with second handrail 8 in 4 upper ends of sampling tube, first handrail 3 seals barrel 1 and connects through the screw thread, be convenient for demolish, second handrail 8 that 4 upper ends of sampling tube set up is convenient for rotate sampling tube 4, when the sampling tube 4 is taken out to needs, with

first handrail

3 and 1 separation of barrel, then take out the sampling tube 4 from barrel 1, the rammed soil sample is handled respectively in the sample chamber 6.

In order to prevent rammed earth at different positions from being mixed into the barrel body 1, the barrel body 1 is provided with a protective cover 9 positioned outside the sampling port 5, the baffle 7 is rotationally fixed on the barrel body 1, the outer end of the baffle 7 is provided with a sealing head 10, the sealing head 10 is contacted with the protective cover 9 to seal the sampling port 5 after the baffle 7 rotates, a spring 11 is arranged between the baffle 7 and the barrel body 1, and the spring 11 pushes the baffle 7 to enable the sealing head 10 to be matched with the protective cover 9 to close the sampling port 5; when squeezing into barrel 1 in ramming earth, sealed head 10 keeps off sample connection 5 with the cooperation of visor 9, in the in-process ramming earth that squeezes into in barrel 1 can not enter into sample chamber 6, and the rotation direction when barrel 1 is beaten is owing to there is the protection of visor 9, ramming earth can be pushed open by visor 9 earlier, can not say that baffle 7 backs down and enter into barrel 1 in, spring 11 promotes baffle 7 and seals sample connection 5, owing to there is the existence of visor 9, baffle 7 can not receive under the effect of ramming earth, can avoid pushing open baffle 7 and get into barrel 1 by ramming earth.

In order to control the baffle 7 conveniently, a yielding groove 12 is formed in the position, corresponding to the baffle 7, of the sampling cylinder 4, and when the sampling cylinder 4 rotates to the position, corresponding to the baffle 7, of the yielding groove 12, the spring 11 pushes the baffle 7 to seal the sampling port 5; form between sampler barrel 4 and the barrel 1 and step down groove 12, when sampler barrel 4 rotated backplate 7 and was in the groove 12 of stepping down, baffle 7 only received the thrust of spring 11, can keep off sample connection 5, and when sample connection 5 was opened to needs, rotated sampler barrel 4, sample connection 5 was opened after 4 promotion baffle 7 made baffle 7 rotate.

For guaranteeing to take out sampler barrel 4 smoothly, be equipped with the chamber 13 that holds that is located the 5 positions of sample connection on the barrel 1, can arrange in holding chamber 13 after baffle 7 rotates, make baffle 7 rotate the back when sampler barrel 4 rotates the back, baffle 7 can enter into and hold chamber 13 in, can not influence the vertical slip of sampler barrel 4 in barrel 1, is convenient for take out sampler barrel 4.

Compared with the prior art, the utility model has the following beneficial effects: when sampling, the sampling port is in a closed state, so that an unnecessary rammed soil sample cannot be mixed, and when sampling is needed, the sampling port is opened, so that rammed soil can enter the sampling cavity, and sampling is finished; the sample position can pinpoint, guarantees the accuracy of sample, and because there is not the rammed earth of other positions to sneak into, the sample result is more accurate to guarantee for follow-up construction provides.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model.
