Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling devices, and in particular to a soil pollution assessment sampling device. Background Technology

[0002] Soil sampling is a commonly used soil testing method used to collect qualitative and quantitative information from the soil. It can be used to measure soil properties, collect samples, estimate ongoing environmental impacts, and monitor changes in soil quality, thereby identifying potential hazards.

[0003] Chinese patent CN220542496U discloses a soil pollution sampling device. It includes an outer ring frame, a middle frame housed within the outer frame, and an inner frame housed within the middle frame. The middle frame and the outer frame are connected by pivots on both sides along a first radial direction; the inner frame and the middle frame are connected by pivots on both sides along a second radial direction; the first radial direction and the second radial direction are two mutually perpendicular directions on the same plane; and the outer wall of the outer frame extends downwards with support legs.

[0004] Regarding the aforementioned technologies, it has been found that existing soil pollution sampling devices cannot adjust the size of the soil sampling trench according to actual needs during use, which limits their application and also prevents simultaneous and rapid multi-group sampling operations. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a soil pollution assessment sampling device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A soil pollution assessment sampling device includes a mounting base, which comprises a housing and an operating frame. The operating frame is symmetrically mounted on both sides of the housing and is fixedly connected to the housing. A sampling rod is rotatably mounted on the lower end face of the housing, and a drive motor for driving the sampling rod to rotate is mounted on the upper end face of the housing. A sampling head is fixedly mounted on the lower end of the sampling rod, and two sets of adjustable supports are symmetrically mounted on the upper end face of the sampling head. The lower ends of the adjustable supports are rotatably connected to the sampling head, and a movable seat for adjusting the width of the adjustable supports is slidably mounted on the sampling rod.

[0008] As a preferred embodiment, the housing includes a main housing and a positioning sleeve for rotating the sampling rod. The positioning sleeve is installed on the lower end face of the main housing and is fixedly connected to the main housing.

[0009] As a preferred embodiment, the sampling rod includes a main rod and a sampling sleeve. The sampling sleeve is installed at the lower end of the main rod and is fixedly connected to the main rod. Positioning grooves are symmetrically formed on the outer surface of the sampling sleeve.

[0010] As a preferred embodiment, the sampling head includes a spiral shell and a triangular head, the spiral shell being sleeved and fixed on the sampling sleeve, and the triangular head being fixedly installed on the lower end face of the spiral shell.

[0011] As a preferred embodiment, the spiral shell includes a middle sleeve and spiral blades. The middle sleeve has a connection hole for connecting with the sampling sleeve, and the spiral blades are sleeved and fixed on the outer surface of the middle sleeve.

[0012] As a preferred embodiment, the adjustable bracket includes a base rod and a top rod, the base rod being rotatably mounted on the middle sleeve, and the top rod being rotatably mounted on the head of the base rod.

[0013] As a preferred embodiment, the movable seat includes a collar and a positioning shell that cooperates with the positioning groove. The collar is sleeved and installed on the sampling sleeve, and the positioning shell is symmetrically arranged on the inner side of the collar. The positioning shell and the collar are integrally formed, and a locking screw is installed in the positioning shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By installing a sampling rod and a drive motor on the mounting base, this application ensures that the sampling rod can be rotated by the drive motor during use. The sampling rod is designed with a main rod and a sampling sleeve that work together. When in use, the main rod can drive the sampling sleeve to perform sampling operations. In order to facilitate rapid and repeated sampling, a sampling head, an adjustable bracket, and a movable seat are installed on the sampling sleeve. This allows for soil breaking and loosening before sampling. After breaking and loosening the soil, sampling can be easily performed through the sampling sleeve. Moreover, by designing the sampling head with a spiral shell and a triangular head that work together, it is easy to quickly break through and penetrate relatively hard soil. The adjustable bracket can easily expand the working width of the loosening operation. Attached Figure Description

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, a soil pollution assessment sampling device includes a mounting base 1, which includes a housing 11 and an operating frame 12. The operating frame 12 is symmetrically installed on both sides of the housing 11 and is fixedly connected to the housing 11. A sampling rod 2 is rotatably installed on the lower end face of the housing 11, and a drive motor 3 for driving the sampling rod 2 to rotate is installed on the upper end face of the housing 11. A sampling head 4 is fixedly installed on the lower end of the sampling rod 2. Two sets of adjustable supports 5 are symmetrically installed on the upper end face of the sampling head 4. The lower end of the adjustable supports 5 is rotatably connected to the sampling head 4, and a movable seat 6 for adjusting the width of the adjustable supports 5 is slidably installed on the sampling rod 2. By designing the mounting base 1 into a structure where the housing 11 and the operating frame 12 cooperate, the equipment can be operated via the two operating frames 12 when easy to use. A sampling rod 2 is rotatably mounted on the lower end face of the housing 11, allowing for stable rotation via a drive motor 3. This enables the sampling rod 2 to drive the sampling head 4 to dig holes in the soil. Two sets of adjustable supports 5 are symmetrically mounted on the upper end face of the sampling head 4 to widen the hole size during rotation. The width of the hole can also be adjusted by sliding the movable seat 6 as needed, making it more convenient to use. The housing 11 includes a main housing 111 and a positioning sleeve 112 for rotatably mounting the sampling rod 2. The positioning sleeve 112 is mounted on the lower end face of the main housing 111 and is fixedly connected to the main housing 111. By designing the housing 11 into a structure in which the main housing 111 and the positioning sleeve 112 cooperate, the operating frame 12 can be installed through the main housing 111 when it is easy to use, while the positioning sleeve 112 ensures that the sampling rod 2 can be stably rotated and installed for use.

[0028] Reference Figure 3 As shown, the sampling rod 2 includes a main rod 21 and a sampling sleeve 22. The sampling sleeve 22 is installed at the lower end of the main rod 21 and is fixedly connected to the main rod 21. Positioning grooves 221 are symmetrically provided on the outer surface of the sampling sleeve 22. By designing the sampling rod 2 into a structure where the main rod 21 and the sampling sleeve 22 cooperate, the sampling sleeve 22 can be stably installed through the main rod 21 for easy use, and soil samples can then be collected through the sampling sleeve 22. Simultaneously, the symmetrically provided positioning grooves 221 on the outer surface of the sampling sleeve 22 facilitate the flexible sliding of the movable seat 6 along the direction of the positioning grooves 221 after it is fitted onto the outer surface of the sampling sleeve 22.

[0029] Reference Figure 4 and Figure 5As shown, the sampling head 4 includes a spiral shell 41 and a triangular head 42. The spiral shell 41 is fitted and fixed onto the sampling sleeve 22, and the triangular head 42 is fixedly installed on the lower end face of the spiral shell 41. By designing the sampling head 4 with a structure in which the spiral shell 41 and the triangular head 42 cooperate, it is easy to use. The spiral shell 41 ensures stable insertion into the soil during rotation, while the triangular head 42 ensures better soil breaking. The spiral shell 41 includes a middle sleeve 411 and a spiral blade 412. The middle sleeve 411 has a connection hole 413 for connecting to the sampling sleeve 22, and the spiral blade 412 is fitted and fixed onto the outer surface of the middle sleeve 411. By designing the spiral shell 41 with a structure in which the middle sleeve 411 and the spiral blade 412 cooperate, it ensures that the middle sleeve 411 is connected to the sampling sleeve 22 during use, the spiral blade 412 enables drilling operations in the soil, and the connection hole 413 ensures that it can be connected and fixed with bolts during use.

[0030] Reference Figure 1 and Figure 5 As shown, the adjustable bracket 5 includes a base rod 51 and a top rod 52. The base rod 51 is rotatably mounted on the middle sleeve 411, and the top rod 52 is rotatably mounted on the head of the base rod 51. By designing the adjustable bracket 5 into a structure in which the base rod 51 and the top rod 52 cooperate, the usable width of the adjustable bracket 5 can be changed by adjusting the angle between the base rod 51 and the top rod 52 when it is easy to use.

[0031] Reference Figure 1 and Figure 4 As shown, the movable seat 6 includes a collar 61 and a positioning shell 62 that mates with the positioning groove 221. The collar 61 is fitted onto the sampling sleeve 22, and the positioning shell 62 is symmetrically arranged on the inner side of the collar 61. The positioning shell 62 and the collar 61 are integrally formed, and a locking screw 621 is installed in the positioning shell 62. By designing the movable seat 6 with a structure in which the collar 61 and the positioning shell 62 mate, it is easy to use by fitting the collar 61 onto the sampling sleeve 22. By setting the positioning shell 62 on the collar 61 to mate with the positioning groove 221, it is ensured that the movable seat 6 can slide and adjust along the direction of the positioning groove 221 during use. After the position is adjusted, it can be locked by the locking screw to ensure that the adjustable bracket 5 can be used with a stable width during rotation.

[0032] In this embodiment, during actual use, the movable seat 6 and the sampling head 4 are fitted onto the sampling sleeve 22 of the sampling rod 2. The sampling head 4 is fixed to the sampling sleeve 22 by bolts. Then, the position of the movable seat 6 is slidably adjusted as needed to change the width of the adjustable bracket 5. After adjusting the width of the adjustable bracket 5, the locking screw 621 can be rotated to lock the movable seat 6. Then, the drive motor 3 can be started to drive the sampling rod 2, the sampling head 4, and the adjustable bracket 5 to rotate. During the operation, the sampling head 4 is used to break the soil, and the adjustable bracket 5 is used to widen the width of the trench. After the soil trench is completed, the equipment is removed from the soil. Then, the sampling head 4, the adjustable bracket 5, and the movable seat 6 are removed from the sampling sleeve 22, and then the sampling sleeve 22 is directly inserted into the soil for multiple sampling.
