Detailed Description

Referring to fig. 2 in combination, according to an embodiment of the present invention, there is provided a sampling device, including: the sampling device comprises a sampling tube 1, a venting mechanism 2 and a sealing member 3, wherein the venting mechanism 2 is connected with the sampling tube 1 and extends to the bottom of the sampling tube 1 along the length of the sampling tube 1, the sampling tube 1 is provided with a sampling port, the sealing member 3 is detachably and hermetically connected to one end of the sampling tube 1 far away from the sampling port to form a seal for one end, and the sealing member 3 is positioned outside the sampling tube 1 before sampling, namely is not assembled at one end, so that the communication between one end and the external atmosphere is ensured. Among this technical scheme, this embodiment is fit for carrying out the soil sample in the comparatively soft area of soil, sample tube 1 when this device is impressed the soil layer and reachs suitable sampling depth after, utilize sealing member 3 to get up the one end that sample tube 1 deviates from the sample connection is sealed, after that, rock sample tube 1 slightly, make the soil sample and the soil layer disconnection in sample tube 1, at this moment, the air just also enters into sample tube 1 bottom along air-breather 2, under the effect of atmospheric pressure, when this device is mentioned, can prevent that the soil sample from falling out in sample tube 1, and the soil sample can not be in sample tube 1 internal disturbance, the accuracy of detection has been ensured, and simultaneously, this device convenient to carry, and easy operation can show improvement sampling efficiency.

As a specific embodiment, the sealing member 3 is an inflatable and deflatable balloon.

In this embodiment, before sampling, the gasbag that sealing member 3 can fill out the gassing does not put into sampler barrel 1 promptly, after sampler barrel 1 impresses the soil layer and reaches suitable sample depth, put into the gasbag from sampler barrel 1 top, then aerify to the gasbag, can seal sampler barrel 1 top after the gasbag inflation, then slightly rock sampler barrel 1, make the soil sample and the soil layer disconnection in sampler barrel 1, at this moment, the air just also enters sampler barrel 1 bottom along ventilation mechanism 2, just so can utilize the atmospheric pressure, when sampler barrel 1 is lifted, the soil sample in sampler barrel 1 just can not drop, when needing to take out the soil sample from sampler barrel 1, only need to deflate the gasbag and make it lose the sealed of sampler barrel 1 top can.

As a specific embodiment, the number of the venting means 2 is two, and the two venting means 2 are respectively located at both sides of the sampling tube 1.

In this embodiment, when the number of the venting mechanism 2 is one, the cost is the lowest, but if only one venting mechanism 2 is provided, the venting mechanism 2 can not play a role in venting in case of being blocked during sampling, and further the sampling failure can be caused, and the sampling barrel 1 is provided with two venting mechanisms 2 which can ensure both venting and the cost, and when the two venting mechanisms 2 are respectively positioned at two sides of the sampling barrel 1, the synchronous air entering the bottom of the sampling barrel 1 from two sides can be ensured.

As a specific embodiment, the venting means 2 is attached to the outer surface of the withdrawal chimney 1.

In the present embodiment, the venting means 2 may be attached to the outer surface or the inner surface of the sampling tube 1, and preferably, the venting means 2 is attached to the outer surface of the sampling tube 1, and if the venting means 2 is attached to the inner surface of the sampling tube 1, the sampling of the sampling tube 1 may be affected.

Specifically, the ventilation mechanism 2 comprises a ventilation pipe 21 and an insertion rod 22, the ventilation pipe 21 is arranged on the outer surface of the sampling tube 1, and the insertion rod 22 is detachably connected in the ventilation pipe 21.

In this embodiment, preferably, the vent pipe 21 is fully welded on the outer surface of the sampling cylinder 1, when the sampling cylinder 1 is pressed into the soil layer for sampling, the vent pipe 21 will move downward along with the sampling cylinder 1, and after reaching a specified sampling depth, the plug rod 22 is detached from the vent pipe 21, so that the vent pipe 21 will be in an open state, and air will enter the bottom of the sampling cylinder 1 along the vent pipe 21, of course, in order to ensure that the plug rod 22 can dredge the vent pipe 21, the length of the plug rod 22 must be greater than the length of the vent pipe 21.

In a specific embodiment, an internal thread is provided in the vent pipe 21, an external thread is provided on the insert rod 22, and the insert rod 22 is screwed into the vent pipe 21.

In this embodiment, preferably, only a small amount of internal threads need to be arranged in the vent pipe 21, and the corresponding position of the plunger 22 is provided with external threads, so that the plunger 22 can be screwed into the vent pipe 21 or screwed out of the vent pipe 21 quickly, and after the sampling cylinder 1 is pressed into a proper sampling depth, the plunger 22 is screwed out of the vent pipe 21, so that the vent pipe 21 can be in a dredging state.

In a specific embodiment, the diameter of the insertion rod 22 is smaller than the inner diameter of the vent pipe 21, and the insertion rod 22 is movably inserted into the vent pipe 21.

In this embodiment, since the diameter of the plunger 22 is smaller than the inner diameter of the vent pipe 21, the plunger 22 is movably placed in the vent pipe 21, and when the sampling cylinder 1 is pushed to a proper sampling depth, the plunger 22 is inserted into the vent pipe 21 to open the vent pipe 21, or the plunger 22 is used to open the vent pipe 21 while sampling with the sampling cylinder 1.

In one embodiment, the plunger 22 has a bent portion at one end.

In the embodiment, when the insertion rod 22 is screwed into the vent pipe 21, one end of the insertion rod 22 is bent to facilitate screwing the insertion rod 22; when the inserting rod 22 is movably inserted into the air pipe 21, one end of the inserting rod 22 is bent to prevent the inserting rod 22 from completely falling into the air pipe 21 when the inserting rod 22 is used to dredge the air pipe 21.

In a particular embodiment, the bottom of the vent tube 21 is flush with the bottom of the withdrawal chimney 1.

In this embodiment, it is preferable that the bottom of the vent pipe 21 is flush with the bottom of the sampling tube 1, and if the bottom of the vent pipe 21 is lower than the bottom of the sampling tube 1, the vent pipe 21 will contact the soil first during sampling, which will hinder the sampling of the sampling tube 1; if the bottom of the vent tube 21 is higher than the bottom of the sampling tube 1, it may happen that air cannot reach the bottom of the sampling tube 1 from the vent tube 21, and therefore it is most suitable that the bottom of the vent tube 21 is flush with the bottom of the sampling tube 1.

As a specific embodiment, the sampling tube 1 is further provided with a holding part 4, and the holding part 4 is close to the top of the sampling tube 1.

In the embodiment, the arrangement of the holding part 4 facilitates the operation of the sampling tube 1 by an operator for sampling, wherein the holding part 4 can be two handles which are respectively welded on the outer surface of the sampling tube 1 from the left side and the right side; or a stick-shaped object movably penetrates through the wall body of the sampling tube 1 from a position close to the top of the sampling tube 1, when the sampling tube is in the latter mode, the holding part 4 can be taken out firstly before the sampling tube 1 is sealed by the air bag, and the holding part 4 is inserted and connected back after the air bag is put in and the top of the sampling tube 1 is sealed.

It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention. The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
