Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 3, a refined soil sampling device for soil detection includes a power system 1, a transmission system 2, a drill string 3, and a limit system 4. The power system 1, the transmission system 2 and the drill string 3 are connected in sequence, and the limiting system 4 and the drill string 3 are in a separable state.
The power system 1 drives the drill stem 3 to rotate and operate, and any power device such as a motor, a diesel engine and the like is adopted; the transmission system 2 transmits and distributes the energy of the power system 1 to a drill string 3 and comprises units such as a base, a reducer, a clutch, a bearing, a chain and the like; the stop system 4 keeps the drill string 3 vertical and non-deviated during operation. The conventional connection mode is adopted to driving system 1, transmission system 2 and drilling string 3, the utility model discloses no longer describe herein.
The limiting system 4 comprises a sleeve 42, a pedal plate 41 arranged at the top end of the sleeve 42 and extending outwards, and a plurality of groups of positioning nails 43 arranged at the tail end of the sleeve 42, and in the concrete implementation, before formal sampling, the limiting system 4 is placed at a sampling point, the positioning nails 43 are nailed into soil, and the pedal plate 41 can be further stepped to make the positioning nails firmer; during sampling, the drill string 3 is inserted into the sleeve 42, and the limiting system 4 can avoid position deviation in the sampling process when downward drilling sampling is carried out.
The drill string 3 is a hollow cylindrical structure, and the tail end of the drill string is a saw-tooth-shaped drill bit 5; during operation, soil is collected into the cylinder of the drill string 3 so that the entire soil profile can be studied by collecting one sample. In order to facilitate taking out of a soil sample, a sample pressing system 6 capable of moving up and down is installed in a drill string 3 cylinder, a plurality of groups of vertical linear holes 31 are formed in the cylinder wall of the drill string 3, the sample pressing system 6 can slide up and down along the linear holes 31, the sample pressing system 6 comprises a connecting rod 61 arranged in the drill string 3 cylinder, a pressing plate 63 connected with the tail end of the connecting rod 61 and a plurality of groups of handles 62 connected with the side wall of the top end of the connecting rod 61, one end of each handle 62 is fixedly connected with the connecting rod 61, and the other end of each handle extends outwards from. Before sampling, the sample pressing system 6 slides downwards along the linear hole 31, and the pressing plate 63 is leveled with the drill 5; in the specific sampling process, the drill string 3 is driven by the power system 1 and the transmission system 2 to rotate downwards, soil samples enter the barrel of the drill string 3, the sample pressing system 6 slides upwards along the linear hole 31 along with the increase of the samples, and when the sampling is finished, the samples can be extruded out through the pressing plate 63 as long as the handle 62 is pressed downwards.
In order to take out a sample conveniently, the side wall and the bottom of the pressing plate 63 are both provided with protruding ridges, so that soil can be extruded out quickly, and soil adhered to the inner wall of the drill column 3 can be scraped.
In order to facilitate the operation, two groups of symmetrical handles 7 are arranged on the transmission system 2, which is beneficial to the operation of extraction and the like of the system by workers in implementation.
Because the length that the system of pressing a sample 6 slided upwards equals the degree of depth of sample, for the visual observation, be equipped with length scale sign on the connecting rod 61 outer wall, length scale sign corresponds with linear hole 31 position.
In order to improve the performance of the drill string 3, a plurality of groups of reinforcing ribs 32 which are uniformly distributed are arranged on the outer wall of the drill string 3, so that the strength of the drill string 3 can be improved on one hand, and the drilling efficiency can be improved on the other hand.
