Description

Technical Field

[0001] The utility model belongs to the technical field of sampling devices, and in particular relates to a soil detection sampling device. Background Art

[0002] In order to better develop, manage and maintain the land, it is necessary to analyze the soil conditions of the land through sampling and testing, and formulate corresponding management measures based on the test results.

[0003] The Chinese patent with publication number CN220583803U discloses a soil sampling device, including a bracket and a sampling tube, wherein the surface of the bracket is threadedly connected with a first threaded rod, and one end of the first threaded rod is connected with a second threaded rod through a threaded tube. The first threaded rod and the second threaded rod are assembled together by using a threaded tube, and the number of threaded rods is added or reduced to facilitate sampling of soils of different depths. On the one hand, the flexibility and applicability of the sampling assembly are improved, and on the other hand, it is easy to carry after disassembly, which greatly improves the convenience when carrying and reduces the space occupied. Secondly, the structure is simple, reliable, and low in cost. During the sampling process, the friction between the feet of the sampling personnel and the bracket can be greatly enhanced, the probability of the soles of the sampling personnel slipping can be reduced, the stability during the sampling process can be ensured, and the bracket can be prevented from rotating with the sampling tube. At the same time, the comfort of the feet of the sampling personnel can be improved, and the practicability is strong and worthy of promotion.

[0004] However, in actual use, although the sampling depth of the sampling barrel can be controlled by adding a threaded barrel and a threaded rod, the threaded rod needs to be threadedly inserted into the bracket, which causes the threaded barrel to be unable to pass through the bracket. That is, when the above-mentioned sampling barrel is to be gradually drilled into deeper soil layers, the entire device needs to be taken out from the borehole, and then the threaded rod under the bracket needs to be disassembled and assembled through the threaded barrel and the threaded rod, so as to extend the drilling depth of the sampling barrel. That is, when the above-mentioned device gradually deepens the drilling depth, the entire device needs to be taken out multiple times, and the threaded barrel and the threaded rod need to be disassembled and assembled. The whole process is relatively labor-intensive and cumbersome, which is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a soil detection sampling device to solve the problem that the existing sampling devices mentioned above are relatively labor-intensive when used.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil detection sampling device, comprising

[0007] The bracket has support plate groups installed on both sides, a through hole is opened on the top of the bracket, and a plurality of sink grooves and through grooves are opened which are distributed at intervals around the through hole, and the sink grooves and through grooves are connected to the through hole;

[0008] The drill rod assembly includes a threaded rod and a control handle. A mounting platform is fixed on the top of the threaded rod. An internal threaded hole is formed on the top of the mounting platform. A threaded protrusion is provided at the bottom of the threaded rod. The threaded protrusion is matched with the internal threaded hole. The control handle is threadedly inserted into the internal threaded hole.

[0009] The connecting piece has a limiting protrusion on the side wall, the connecting piece is matched with the through hole, the limiting protrusion abuts against the sink groove, and the limiting protrusion is matched with the through groove, a step groove is provided on the top of the connecting piece, the threaded rod is threadedly inserted in the step groove, and the hanging platform is matched with the top of the step groove, a limiting column is fixed on the top of the limiting protrusion, a limiting groove is provided on the bottom of the limiting protrusion, and the limiting column is matched with the limiting groove;

[0010] Sampling cylinder, installed at the bottom of the threaded rod.

[0011] The principle and effect of this technical solution:

[0012] 1. Through the arrangement of the through hole, the sink groove and the through slot, the position of the connector can be abutted against the sink groove through the limiting protrusion, so that the connector is hung on the through hole and cannot rotate; and the position of the limiting protrusion can correspond to the through slot, so that the connector and the limiting protrusion can slide along the through hole and the through slot to the bottom of the bracket, so that when the device extends the threaded rod, the connector can play the function of stopping rotation or passing according to needs, avoiding the restriction of the bracket on the movement of the connector, so that the installation of the connector and the threaded rod can be performed above the bracket without taking out the entire device, which saves more manpower.

[0013] 2. By setting the limit column and the limit groove, when multiple connecting parts abut against each other, the lower limit column can be inserted into the upper limit groove, so that the connecting parts can be prevented from rotating. By making the threaded protrusion at the bottom of the threaded rod match the internal threaded hole on the hanging platform, when the threaded rods are connected and assembled, the threaded protrusion of the upper threaded rod can be screwed into the internal threaded hole below, and then the two threaded rods can be prevented from rotating through the abutment between the connecting parts, thereby improving the connection stability between the threaded rods and making it difficult for the threaded rods to separate.

[0014] 3. When connecting the threaded rod to the threaded rod, the hanging platform of the threaded rod below is hung in the stepped groove. First, take out a new connecting piece, and place the connecting piece on the top of the original connecting piece, and make the limit column and the limit groove face each other. Then, take out the threaded rod to be added, and then put an independent connecting piece on the threaded rod. After screwing the bottom thread of the threaded rod on the two stacked connecting pieces located above, continue to screw so that the threaded protrusion of the threaded rod cooperates with the internal threaded hole of the hanging platform until it can no longer rotate. Then, by pulling the upper threaded rod, the limiting protrusion on the connecting piece at the lower end is disengaged from the sink groove, and after rotating it to correspond to the through groove, the threaded rod is lowered to move the two mutually abutting connecting pieces to the bottom of the bracket. At this time, the threaded rod is rotated and the position of the independent connecting piece installed before is controlled so that the limiting protrusion of the independent connecting piece corresponds to the sink groove, and the independent connecting piece is placed in the sink groove, and a new round of drilling work can be carried out.

[0015] 4. The installation, control and operation are performed above the bracket, thereby saving operation time, and the detachable setting is easy to carry, and the anti-rotation setting between the threaded rods is more stable.

[0016] The utility model is further configured as follows: the control handle comprises a hand grip rod and a connecting rod, the hand grip rod is fixed above the connecting rod, and the connecting rod is threadedly inserted into the internal thread hole.

[0017] The principle and effect of this technical solution: by inserting the connecting rod into the internal threaded hole, the connecting rod can be disassembled relative to the threaded cover, and can be rotated by the hand handle, so that the staff can easily control the rotation of the connecting rod and the threaded rod.

[0018] The utility model is further configured as follows: the support plate group includes an upper support plate, a lower support plate and a support side plate, the upper support plate is slidably inserted on the lower support plate, the top of the upper support plate is connected to the bracket, and the support side plate is hinged to the bottom of the outer wall of the lower support plate.

[0019] The principle and effect of this technical solution: by arranging the upper support plate, the lower support plate and the support side plate, when the support side plate stabilizes the lower support plate, the height of the bracket can be controlled by the degree of overlap between the upper support plate and the lower support plate, so that the sampling cylinder and the upper threaded rod are driven to rise a certain distance through the bracket, thereby leaving the height required for the original connecting part to descend after the new threaded rod and connecting part are installed, that is, after the new threaded rod is connected through the connecting part, the two connected connecting parts can be moved to the bottom of the bracket through the through hole and the through groove by extraction (because the sampling cylinder rises and leaves room for descent, there is no need to drill to make way, making it easier for the device to return to the normal operating position), and after the limit protrusion on the new connecting part abuts against the sink, the height of the sampling cylinder can be controlled by the control handle.

[0020] The utility model is further configured as follows: a spring is installed in the lower support plate, and the top of the spring abuts against the bottom of the upper support plate.

[0021] The principle and effect of this technical solution: the setting of the spring enables the operator to increase the number of threaded rods and the number of connecting parts, and after the operator removes the downward external force, the spring can drive the upper support plate to rise a certain distance due to its own elastic force.

[0022] The utility model is further configured as follows: fixed plates are fixed on both sides of the bottom of the outer wall of the lower support plate, a anti-rotation plate is installed between the two fixed plates, the anti-rotation plate is located at the bottom of the inner wall of the fixed plate, one end of the supporting side plate is hinged to the inner side of the two fixed plates, and the bottom edge of the hinged end of the supporting side plate is abutted against the top edge of the anti-rotation plate.

[0023] The principle and effect of this technical solution: by setting the anti-rotation plate, when the supporting side plate is rotated to horizontal, the bottom edge of the hinged end abuts against the anti-rotation plate, so that the supporting side plate cannot continue to rotate. The operator can limit the position of the lower supporting plate relative to the ground\supporting side plate by stepping on the supporting side plate, so that the bracket remains stable when in use.

[0024] The utility model is further configured such that: the projection of the outer edge of the limiting protrusion on the horizontal plane is located on the inner side of the projection of the sampling tube on the horizontal plane.

[0025] The principle and effect of this technical solution: by limiting the outer edge size of the limiting protrusion, the limiting protrusion can be freely raised and lowered in the sampling hole drilled by the sampling tube, avoiding the interference and obstruction of the soil layer on the movement of the limiting protrusion and the connecting piece.

[0026] The utility model is further configured as follows: two sinking grooves and two through grooves are respectively provided.

[0027] The principle and effect of this technical solution: the setting of two recessed grooves and two through holes enables the limiting protrusions to also have two, so that when the connecting part is hung in the recessed groove through the limiting protrusion, the force can be well distributed, the force is more evenly distributed, and a better anti-rotation effect can be achieved. Moreover, by rotating 90°, the two limiting protrusions can correspond to the two through grooves respectively, thereby avoiding the situation where some limiting protrusions correspond to some through grooves while a few protrusions do not correspond to the remaining through grooves.
