Patent application number CN201721336217.5 provides a geological survey sampling device, through combining two and boring soil pieces and rotatory first rotary rod and second rotary rod, can dig earth earlier, use the ware of digging a ball of getting earth to sample to whole earth again, nevertheless in the in-service use process, dig the ball ware and can only gather the surface soil, to the soil of buried depth at ten to forty centimetres within ranges, because lack necessary excavation mechanism and lead to being difficult to the collection, influence the detection of soil.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a geological survey sampler can gather the soil of buried depth at ten to forty centimetres within ranges, and the device simple structure can provide complete column soil sample, is favorable to the detection of soil.

The geological survey sampler of the utility model comprises a threaded sleeve; the supporting frame is fixedly connected with the threaded sleeve; the first screw is sleeved with the threaded sleeve, and a conical spiral drill bit is fixed at the bottom of the first screw; a passage extending through the conical auger bit and the first screw in a direction along the length of the first screw; and the driving piece is fixed at the top of the first screw rod.

During operation, place the support frame in the collection point, drive first screw rod through the driving piece and rotate downwards along the screw sleeve, and then make toper auger bit bore into soil downwards, because the inside passageway that is equipped with of first screw rod, the soil of gathering is along with toper auger bit to creep into the access passage downwards in, after the sampling is accomplished take out in following the passageway with the soil of gathering can.

Preferably, the device further comprises a plug fixedly connected with the channel and a second screw inserted into the first screw and fixedly connected with the plug, and the length of the second screw is adapted to the length of the channel.

End cap and passageway inner wall accessible threaded connection, in following soil entering passageway, the second screw rod inserts in the soil, the screw thread on second screw rod surface has increased the area of contact with soil, conveniently takes out soil wholly from the passageway.

Preferably, the support frame includes connecting rod and locating wedge, the connecting rod circumference is evenly fixed in the threaded sleeve outer wall, the connecting rod slope sets up downwards, the connecting rod end is equipped with the through-hole that supplies the locating wedge to wedge.

The positioning wedge is used for fixing the supporting frame, after the supporting frame is placed at a collection point, one end of the positioning wedge penetrates through the through hole and is wedged into soil, the conical auger bit is prevented from being incapable of screwing into the soil due to too large resistance, and the size of the top end of the positioning wedge is larger than the aperture of the through hole.

Preferably, the driving piece is a rotating handle, and one end of the rotating handle is fixedly connected with the first screw rod.

The utility model has the advantages that: the soil with the buried depth within the range of ten to forty centimeters can be collected, and the device has the advantages of simple structure and convenient carrying, can provide a complete cylindrical soil sample, and is favorable for the detection of the soil.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-3, the geological survey sampler of the present invention comprises a threaded sleeve 1; the supporting frame is fixedly connected with the threaded sleeve 1; the first screw rod 2 is sleeved with the threaded sleeve 1, and a conical spiral drill bit 3 is fixed at the bottom of the first screw rod 2; a channel 4 extending through the conical auger bit 3 and the first screw 2 along the length of the first screw 2; and a driving member fixed to the top of the first screw 2. The device also comprises a plug 5 fixedly connected with the channel 4 and a second screw 6 inserted into the first screw 2 and fixedly connected with the plug 5, wherein the length of the second screw 6 is adapted to the length of the channel 4. The support frame includes connecting rod 7 and locating

wedge

8, 7 circumference of connecting rod are evenly fixed in 1 outer wall of threaded sleeve, 7 slopes of connecting rod set up downwards, 7 ends of connecting rod are equipped with the through hole 9 that supplies locating wedge 8 to wedge. The driving piece is a rotating handle 10, and one end of the rotating handle 10 is fixedly connected with the first screw rod 2.

End cap 5 and the 4 inner wall accessible threaded connection of passageway, in following soil access channel 4, second screw rod 6 inserts in the soil, the screw thread on 6 surfaces of second screw rod has increased the area of contact with soil, conveniently takes out soil wholly from passageway 4. The positioning wedge 8 is used for fixing the supporting frame, after the supporting frame is placed at a collection point, one end of the positioning wedge 8 penetrates through the through hole 9 and is wedged into soil, the conical auger bit 3 is prevented from being incapable of screwing into the soil due to too large resistance, and the size of the top end of the positioning wedge 8 is larger than the aperture of the through hole 9.
