Description

Technical Field

[0001] The utility model relates to the field of soil sampling equipment, in particular to a soil detection sampling equipment with adjustable depth. Background Art

[0002] At present, soil is formed and evolved under the combined effects of multiple soil-forming factors such as parent material, climate, biology, topography, and time. The soil composition is very complex. Existing soil testing needs to detect the content and types of pollutants in the soil, and then determine the degree of soil pollution.

[0003] In the existing soil testing sampling method, if it is necessary to take soil samples from different depths underground, it is necessary to dig a pit of a certain depth, then repair and clean the section, remove the topmost loose soil, and then take samples from the central typical part layer by layer from top to bottom. During the sampling operation, in order to save labor intensity, most of the sampling frames are controlled to descend by electric means. In order to facilitate the secondary transfer after the soil samples are taken out, the surface of the sampling frames mostly has a large opening. During the electric rise and fall process, the soil sample is easy to slip from the opening, affecting the safety of the soil sample during transportation. If the opening size of the sampling frame is reduced, during the descent of the sampling frame, the resistance encountered by the frame embedded in the soil ground becomes larger, and it is also not convenient for the subsequent separation and storage of soil samples of different depths taken out from the inside of the sampling frame.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1 , Figure 4 and Figure 5 The soil detection sampling device with adjustable depth shown includes a liftable sampling tube 1 and a pair of support arms 6 symmetrically distributed on the outside of the sampling tube 1. The sampling tube 1 can be lowered to a designated position according to needs to reach different depths on the ground.

[0025] The surface of the sampling tube 1 is provided with an opening 11 for taking out soil blocks, and the soil sample at the designated position can be cut at the opening 11, so as to take the soil sample at the designated depth. The part of the side surface of the sampling tube 1 facing the opening 11 is composed of a plurality of embedded rods 12 equidistantly distributed along a semicircular track, and the bottom ends of the embedded rods 12 are all in an inverted triangle shape, which can increase the impact force when the embedded rods 12 are embedded in the ground during the descending sampling process, so as to quickly grab the soil sample.

[0026] It also includes a shielding frame 2 that can be located outside the opening 11 and can move up and down. The bottom end of the shielding frame 2 is fixedly connected to an adjustment arm 21, and an observation groove 22 is provided on the surface of the shielding frame 2 facing the outside of the opening 11. In a natural state, as the sampling tube 1 moves upward after the sampling work is completed, the shielding frame 2 can prevent the soil sample from falling from the opening 11, thereby ensuring the safety of the soil sample during transportation. At this time, the groove 22 can be observed to confirm whether the soil sample of the specified thickness is taken from the inside of the sampling tube 1.

[0027] If soil samples need to be taken, the adjusting arm 21 and the shielding frame 2 can be controlled to slide synchronously to expose the opening 11. The shielding frame 2 can be moved to a designated position outside the opening 11 to facilitate taking out the soil sample inside the sampling tube 1. The shielding frame 2 can be flexibly adjusted to meet different work requirements.

[0028] The top of the sampling tube 1 is equipped with a linkage seat 3 that can be raised and lowered synchronously with it, and a driving screw 4 that is compatible with it is installed through the surface of the linkage seat 3, and a driving motor 5 that is compatible with its model is installed on the top of the driving screw 4. When the driving motor 5 is in operation, it can drive the driving screw 4 to rotate, so as to achieve the purpose of controlling the sampling tube 1 to perform the work of descending sampling and ascending to transport soil samples.

[0029] A support 7 coaxial with the sampling tube 1 is arranged above the support 7, a limit horizontal plate 8 is installed on the upper surface of the support 7, a pair of guide rods 31 are symmetrically fixed on the surface of the linkage seat 3, and a pair of through holes for accommodating the guide rods 31 are opened on the surface of the limit horizontal plate 8. When the linkage seat 3 moves up and down, the guide rods 31 move up and down in a direction perpendicular to the limit horizontal plate 8. The guide rods 31 can maintain the linearity of the linkage seat 3 during movement, effectively preventing the sampling tube 1 from deviating during the process of descending for sampling and ascending for transporting soil samples.

[0030] like Figure 2 , Figure 3 As shown, a storage rack 61 is installed on one side of one of the support arms 6 close to the sampling tube 1, and the adjusting arm 21 extends to the inner side of the storage rack 61. The inner cavity of the storage rack 61 is installed with a vertically distributed limiting shaft rod 62, which runs through the storage rack 61, and the adjusting arm 21 can slide along the direction of the limiting shaft rod 62.

[0031] The upper surface of the adjusting arm 21 is provided with a first alignment ring 23 which can slide synchronously therewith, and the upper surface of the first alignment ring 23 is connected with a second alignment ring 24 through a pressure spring 25, and the second alignment ring 24 is installed on the inner top wall of the storage rack 61, and the first alignment ring 23, the pressure spring 25 and the second alignment ring 24 are all surrounded on the outer side of the limiting shaft 62. In the natural state, with the upward movement of the sampling tube 1 after the sampling work is completed, under the elastic potential energy of the pressure spring 25, the shielding rack 2 can prevent the soil sample from falling from the opening 11, thereby ensuring the safety of the soil sample during transportation.

[0032] like Figure 4 As shown, if soil samples need to be taken, the adjustment arm 21 can be controlled to slide along the direction of the limiting shaft 62, and the first alignment ring 23 squeezes the pressure spring 25 to contract. Through the sliding of the adjustment arm 21 and the shielding frame 2, the opening 11 is gradually exposed, and the shielding frame 2 can be moved to a specified position outside the opening 11 according to needs, so as to take out the soil sample at a specified depth inside the sampling tube 1.

[0033] like Figure 4 As shown, the surface of the support arm 6 on which the storage rack 61 is installed is connected to a pair of interception blocks 63 through a rotating shaft. The pair of interception blocks 63 are symmetrically distributed on the left and right sides of the storage rack 61, and the surface of the storage rack 61 is provided with a positioning groove 64 for accommodating the interception blocks 63 to pass through. When the adjustment arm 21 moves to the limit height inside the storage rack 61, the interception block 63 can be controlled to pass through the positioning groove 64, and its end is rotated to the inside of the storage rack 61, which can limit the adjustment arm 21 from sliding downward, thereby preventing the shielding rack 2 from sliding downward, and effectively removing the obstruction caused by the shielding rack 2 to the opening 11 under the elastic potential energy of the pressure spring 25, so as to quickly remove all soil samples inside the sampling tube 1.

[0034] like Figure 2 As shown, a pair of legs symmetrically distributed on the lower surface of the support 7 are respectively inserted into the inner side of a pair of support arms 6, and the support arms 6 can slide along the direction of the legs to adjust the height of the legs and the support arms 6. In the process of soil sampling, if the soil at a specified depth to be sampled is far from the ground, it is necessary to dig a pit and collect cross-sectional soil samples. In order to adapt to the depth of the pit, one of the support arms 6 maintains the initial state against the ground, and the other set of legs and support arms 6 can adjust the height, penetrate into the pit and against its bottom wall, so as to maintain the stability of the entire sampling equipment.

[0035] like Figure 1 As shown, an extension seat 9 is installed on the top of the support 7, and the drive motor 5 is installed on the upper surface of the extension seat 9. The purpose of adding the support 7 is to leave installation space for the drive motor 5 and maintain the stability of the drive motor 5 in the running state.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
