The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Example 1
Referring to fig. 1 to 3, in a first embodiment of the present utility model, a heavy metal contaminated farmland soil sampling device is provided, which can collect soil with a specific depth in a targeted manner by arranging a drilling assembly in a sampling cylinder, so that soil with different depths can be detected during detection, and the accuracy of detection is improved. The positioning assembly and the graduated scale can preset the drilling depth, so that the detection efficiency is improved.
The soil sampler specifically comprises a sampling cylinder 100, wherein two ends of the sampling cylinder are open and the inside of the sampling cylinder is hollow, one end of the sampling cylinder is a sampling end, the other end of the sampling cylinder is a mounting end, and the sampling end is used for drilling into soil for sampling; the drilling assembly 200 comprises a tunneling rod 201 penetrating through the mounting end of the sampling tube 100 and extending into the sampling tube 100, the mounting end is provided with a through hole with the diameter smaller than that of the sampling end, the through hole is in clearance fit with the tunneling rod 201, the free end of the tunneling rod 201 is provided with a tunneling head 202, the largest edge of the tunneling head 202 is in clearance fit with the inner side wall of the sampling tube 100, the tunneling head 202 and the sampling tube 100 are mutually attached, and the tunneling head 202 can freely move along the axial direction of the sampling tube 100; the positioning assembly 300 is slidably sleeved on the outer side of the sampling tube 100, and the graduated scale 400 is arranged on the outer side wall of the positioning assembly 300.
In use, the cartridge 100 and the drilling assembly 200 are first vertically embedded into the soil, and the depth of penetration is visible through the outboard locating assembly 300 and scale 400. When the depth of soil to be sampled is reached, the boring bar 201 and the boring head 202 of the boring bar assembly 200 no longer bore into the soil, and the cartridge 100 continues to be embedded into the soil, thereby sampling the soil at the predetermined depth. The cartridge 100 is then removed to obtain a soil sample.
For convenience, the operator operates the tunneling rod 201, a transverse handle 205 is arranged at the top of the tunneling rod 201, and friction bumps are arranged on the handle 205. The friction bumps may increase the friction on the surface of the handle 201 so that an operator may more firmly grip the ripper shank 201.
Further, two groups of limiting blocks 203 are radially and uniformly arranged in the middle of the rod body of the tunneling rod 201, and the limiting blocks 203 are abutted to the mounting end of the sampling tube 100.
When the sampling tube 100 and the drilling assembly 200 are embedded into the soil to be sampled, the handle 201 is held, the tunneling rod 201 is directly pushed, and the limiting block 203 on the rod body of the tunneling rod 201 is in contact with the mounting end of the sampling tube 100. At this time, the maximum edge of the tunneling head 202 is just at the bottom of the sampling tube 100, at this time, the tunneling rod 201 is directly pushed to drive the sampling tube 100 to be embedded into the soil for sampling, after reaching a predetermined depth, the tunneling rod 201 is not moved or lifted upwards, at this time, the sampling tube 100 is pushed for sampling at the predetermined depth, and then the soil sample is collected, so that the soil sample is prevented from being polluted.
From the above description, it will be appreciated that when drilling into the soil to a predetermined depth of soil, the ripper rod 201 is stationary and the cartridge 100 is pushed to sample. In the embodiment, a through groove is radially formed in one end of the tunneling rod 201, which is close to the tunneling head 201; the inner side walls at the two ends of the through groove are hinged with a blocking rotary rod 204. It is realized that when the predetermined soil depth is reached and the sampling is required, the two sets of blocking rotary rods 204 are lifted upwards along the axial direction of the tunneling rod 201, when the bottoms of the two sets of blocking rotary rods 204 are positioned at the mounting end of the sampling tube 100, the ends of the rotary rods 204 far away from the tunneling head 202 are pressed into the through grooves, so that the ends of the two sets of blocking rotary rods 204 close to the tunneling head 202 are simultaneously inclined outwards, and at the moment, the end faces of the mounting ends are just propped against, and the tunneling head 202 is positioned at the upper part of the sampling tube 100. Then, only the tunneling rod 201 needs to be pushed, and the sampling cylinder 100 can be driven to continue sampling soil at the target position under the action of the blocking rotary rod 204. The sampling cylinder 100 does not need to be pushed, and when the collected soil needs to be taken out, the blocking rotary rod 204 is pushed, so that the working efficiency is improved, and the operation difficulty is reduced.
Further, the heading 202 is a cone bit, which is designed to facilitate more effort-saving insertion into the earth.
Further, two groups of sliding grooves 101 are uniformly formed in the circumferential direction of the outer side wall of the sampling cylinder 100;
The positioning assembly 300 includes: the sampling device comprises a sleeve 301 sleeved on the outer side of the sampling cylinder 100, a sliding block 302 arranged on the inner side wall of the sleeve 301 and matched with the sliding groove 101, and two groups of stop blocks 303 uniformly arranged on the outer side wall of the sleeve 301; the scale 400 is disposed at an end of the sleeve 301 remote from the head 202 and extends upwardly.
In the initial stage, the position of the sleeve 301 is located at the bottom of the sampling tube 100, and as the sampling tube 100 descends, the sleeve 301 slides on the outer side wall of the sampling tube 100 under the action of the stop block 303, and at this time, the scale arranged on the sleeve 301 can observe the tunneling depth at any time, so that the sampling operation can be performed.
Further, the sleeve 301 is radially provided with a threaded hole, and a butterfly damping bolt 304 matched with the threaded hole is arranged in the threaded hole; the free end of the butterfly damper bolt 304 abuts against the cartridge 100 during locking.
It should be noted that, the damping bolts 304 are disposed at two sides of the sleeve 301, so as to limit the position of the sleeve 301 on the sampling tube 100, and thus the purpose of the arrangement is to preset the sampling depth, when the sampling tube 100 reaches the sampling position, the driving rod 201 is lifted upwards at this time under the action of the stop block 303, and the driving head 201 is fixed on the upper portion of the sampling tube 100 under the action of the stop rotary rod 204. At this time, the damping bolt 304 is loosened, the depth of the sampled soil is preset, the damping bolt 304 is locked again, and the sampling cylinder 100 is continuously moved into the soil to collect the soil with the preset depth. There is no need to observe the sampling depth of the cartridge 100 in real time, reducing the difficulty of operation.
Further, the sampling end of the sampling tube 100 is configured as a chamfer design.
It should be noted that, the contact surface between the sampling tube 100 and the soil is reduced, and the chamfering design has a sharp portion, which is more labor-saving when being conveniently inserted into the soil.
Further, the scale mark values of the scale 400 gradually increase from top to bottom. It is thus possible to realize that the scale of the descent of the cartridge 100 is identical to the scale of the ascent of the scale 400, facilitating the observation and recording.
The working principle of the utility model is as follows: firstly, the sleeve 301 is arranged at the relative position of the sampling tube 100 according to the sampling depth, the sampling tube 100 and the drilling assembly 200 are vertically arranged on the soil surface to drill, when two groups of stop blocks 303 on the sleeve 301 are in contact with the ground, the preset depth is reached, the position of the sleeve 301 on the sampling tube 100 is adjusted according to the soil depth required to be acquired again, after the adjustment is finished, the sampling tube 100 continues to downwards sample until the stop blocks 303 are propped against the soil surface, at the moment, corresponding samples are acquired in the sampling tube 100, the sampling tube 100 is taken out of the soil, and the acquired samples are subjected to the next detection treatment.
It should be noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present utility model may be modified or substituted without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered in the scope of the claims of the present utility model.
