Description

Technical Field

[0001] This utility model relates to the field of soil collection technology, and in particular to a wet soil collection device for ecological environment assessment. Background Technology

[0002] As an important tool for ecological and environmental assessment, wet soil sampling devices were designed to meet the need for precise monitoring of the soil environment. In ecological research, agricultural science, and environmental engineering, the analysis of the physicochemical properties and biological characteristics of soil samples is fundamental to assessing ecosystem health, and the standardization of the sampling process and the integrity of the samples directly affect the reliability of subsequent test results. Traditional soil sampling methods rely heavily on manual operation, resulting in low efficiency and poor consistency, making it difficult to meet the standardized sampling requirements of large-scale environmental surveys or long-term fixed-point monitoring.

[0003] Traditional wet soil sampling devices often use a handheld drill to drive the drill rod downwards to obtain soil samples. This method has many inconveniences in actual operation. First, the drill itself is heavy, requiring the operator to expend considerable physical strength to hold and control it stably for extended periods. Second, the drilling process relies entirely on manual control of force and angle, making it difficult to guarantee the accuracy of sampling depth and the consistency of sampling conditions between different points, thus affecting the comparability of data. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wet soil collection device for ecological environment assessment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wet soil sampling device for ecological environment assessment includes a base plate, a support plate fixedly mounted on the base plate, a hydraulic cylinder fixedly mounted on the upper surface of the support plate, two symmetrical I-beams fixedly mounted on the upper surface of the base plate, a guide assembly slidably mounted on the I-beams, a lifting plate fixedly mounted on the output end of the hydraulic cylinder, the lifting plate being fixedly connected to the guide assembly, two connecting plates fixedly mounted on the guide assembly, an mounting plate disposed between the connecting plates, the top end of the mounting plate being fixedly connected to one of the connecting plates by bolts, the bottom end of the mounting plate being fixedly connected to the other connecting plate by screws, a drilling rig fixedly mounted on the mounting plate, a handle fixedly mounted on the drilling rig, and a drill rod assembly connected to the output end of the drilling rig.

[0007] Furthermore, the drill rod assembly includes a drill rod body, both the upper and lower ends of which are provided with a first external thread. A drill bit is threadedly connected to the bottom end of the drill rod body through the first external thread, and a connector is threadedly connected to the top end of the drill rod body through the first external thread. A second external thread is provided at the output end of the drill rig, and the drill rig is fixedly connected to the connector through the second external thread.

[0008] Furthermore, the drill pipe body is composed of two semi-cylindrical sub-tubes.

[0009] Furthermore, the guide assembly includes fixed plates located on the left and right sides of the I-beam, with rollers rotatably mounted between the fixed plates, one end of each roller adhering to the side wall of the I-beam.

[0010] Furthermore, a support foot is fixedly installed at the front end of the base plate, and a self-locking omnidirectional wheel is fixedly installed at the rear end of the base plate.

[0011] Furthermore, a crossbeam is fixedly installed at the top of the I-beam, a support rod is fixedly installed between the crossbeam and the base plate, and a handrail is fixedly installed on one side of the support rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a hydraulic cylinder, mounting plate, and drilling rig, allows for the drilling rig to be fixedly mounted on a connecting plate via the mounting plate when drilling in deep wet soil environments. The drill rod assembly is then connected to the drilling rig, and the drill rod assembly can be stably lowered by the hydraulic cylinder. At the same time, the rotation of the drill rod assembly driven by the drilling rig ensures that the drill rod assembly can cut into the soil layer with constant pressure, avoiding the problem of uneven force caused by manual pressing operation. When the wet soil drilling environment is not convenient for placing the base plate, the mounting plate can be removed, and the drill rod assembly can be driven by the handle to collect wet soil.

[0014] 2. This utility model sets up a drill rod assembly and two separate cylinders. The assembly of the drill rod assembly involves first threading the drill bit to the drill rod body, then threading the connector to the drill rod body, and finally fixing the connector to the drilling machine. After the drill rod body is pulled out, the drill bit and connector are disassembled, and the two separate cylinders are separated from each other, thereby obtaining a cylindrical wet soil sample.

[0015] 3. By setting a guide component, when the hydraulic cylinder drives the lifting plate to move, it simultaneously drives the rollers to roll on the side wall of the I-beam, ensuring that the movement trajectory is not deviated. At the same time, the rolling of the rollers on the side wall of the I-beam effectively counteracts the lateral torque.

[0016] 4. This utility model is equipped with support feet, self-locking casters, and handrails. The operator can position the equipment to the sampling point using the self-locking casters at the bottom of the base plate. The support feet stabilize the equipment and prevent it from sinking. When the sampling work is completed, the operator can hold the handrail and pry the entire equipment to move it in an inclined position using the self-locking casters. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-2 , Figure 5A wet soil sampling device for ecological environment assessment includes a base plate 1, a support plate 2 fixedly installed on the base plate 1, a hydraulic cylinder 3 fixedly installed on the upper surface of the support plate 2, two symmetrical I-beams 4 fixedly installed on the upper surface of the base plate 1, a guide assembly 5 slidably installed on the I-beams 4, a lifting plate 6 fixedly installed at the output end of the hydraulic cylinder 3, the lifting plate 6 being fixedly connected to the guide assembly 5, two connecting plates 7 fixedly installed on the guide assembly 5, an installation plate 8 being provided between the connecting plates 7, the top end of the installation plate 8 being fixedly connected to one of the connecting plates 7 by bolts, the bottom end of the installation plate 8 being fixedly connected to the other connecting plate 7 by screws, a drill rig 9 fixedly installed on the installation plate 8, a handle 10 fixedly installed on the drill rig 9, and a drill rod assembly 11 connected to the output end of the drill rig 9.

[0026] When drilling in deep wet soil environments, the drilling rig 9 is fixedly mounted on the connecting plate 7 via the mounting plate 8. The drill rod assembly 11 is then connected to the drilling rig 9. The drill rod assembly 11 is driven by the hydraulic cylinder 3 to descend stably. At the same time, the rotation of the drill rod assembly 11 driven by the drilling rig 9 ensures that the drill rod assembly 11 can cut into the soil layer with constant pressure, avoiding uneven force caused by manual pressing. When the wet soil drilling environment is not convenient for placing the base plate 1, the mounting plate 8 is removed, and the handle 10 is held by hand. The drill rod assembly 11 is driven by the drilling rig 9 to collect wet soil. When collecting wet soil, the drilling rig 9 stops working, and the drill rod assembly 11 is pulled out of the wet soil by the hydraulic cylinder 3.

[0027] Reference Figure 1-3 Specifically: the drill rod assembly 11 includes a drill rod body 12, both the upper and lower ends of which are provided with first external threads 13. The bottom end of the drill rod body 12 is threadedly connected to a drill bit 14 through the first external threads 13, and the top end of the drill rod body 12 is threadedly connected to a connector 15 through the first external threads 13. The output end of the drilling rig 9 is provided with a second external thread 16, and the drilling rig 9 is fixedly connected to the connector 15 through the second external threads 16. The assembly of the drill rod assembly 11 is as follows: first, the drill bit 14 is threadedly connected to the drill rod body 12; then, the connector 15 is threadedly connected to the drill rod body 12; and finally, the connector 15 is fixedly connected to the drilling rig 9.

[0028] Reference Figure 4 Specifically: the drill rod body 12 is composed of two semi-cylindrical sleeves 17. After the drill rod body 12 is pulled out, the drill bit 14 and the connector 15 are disassembled, and the two sleeves 17 are separated from each other, thereby obtaining a cylindrical wet soil sample.

[0029] Reference Figure 1 , Figure 6Specifically: the guide assembly 5 includes fixed plates 18 located on the left and right sides of the I-beam 4, and rollers 19 are rotatably installed between the fixed plates 18. One end of the rollers 19 is attached to the side wall of the I-beam 4. When the hydraulic cylinder 3 drives the lifting plate 6 to move, it simultaneously drives the rollers 19 to roll on the side wall of the I-beam 4 to ensure that the movement trajectory is not deviated. At the same time, the rolling of the rollers 19 on the side wall of the I-beam 4 effectively counteracts the lateral torque.

[0030] Reference Figure 1 Specifically: a support foot 20 is fixedly installed at the front end of the base plate 1, and a self-locking universal wheel 21 is fixedly installed at the rear end of the base plate 1. The operator uses the self-locking universal wheel 21 at the bottom of the base plate 1 to position the equipment to the sampling point, and the support foot 20 stabilizes the device to prevent it from sinking.

[0031] Reference Figure 1 , Figure 5 Specifically: a crossbeam 22 is fixedly installed at the top of the I-beam 4, and a support rod 23 is fixedly installed between the crossbeam 22 and the base plate 1. A handrail 24 is fixedly installed on one side of the support rod 23. When the data collection work is completed, hold the handrail 24 and pry the entire device so that the device can be moved in an inclined position by means of the self-locking caster 21.

[0032] Working principle: When drilling in deep wet soil environments, the drilling rig 9 is fixedly installed on the connecting plate 7 via the mounting plate 8. The drill rod assembly 11 is then connected to the drilling rig 9. Driven by the hydraulic cylinder 3, the drill rod assembly 11 can be lowered stably. At the same time, the rotation of the drill rod assembly 11 driven by the drilling rig 9 ensures that the drill rod assembly 11 can cut into the soil layer with constant pressure, avoiding the problem of uneven force caused by manual pressing operation. When the wet soil drilling environment is not convenient for placing the base plate 1, the mounting plate 8 is removed, and the handle 10 is held. The drill rod assembly 11 is driven by the drilling rig 9 to collect wet soil. When collecting wet soil, the drilling rig 9 stops working, and the drill rod assembly 11 is pulled out of the wet soil by the hydraulic cylinder 3.

[0033] The assembly of the drill rod assembly 11 involves first threading the drill bit 14 to the drill rod body 12, then threading the connector 15 to the drill rod body 12, and finally fixing the connector 15 to the drilling machine 9. After the drill rod body 12 is pulled out, the drill bit 14 and connector 15 are disassembled, and the two split cylinders 17 are separated from each other, thereby obtaining a cylindrical wet soil sample.

[0034] When the hydraulic cylinder 3 drives the lifting plate 6 to move, it simultaneously drives the roller 19 to roll on the side wall of the I-beam 4, ensuring that the movement trajectory is not deviated. At the same time, the rolling of the roller 19 on the side wall of the I-beam 4 effectively counteracts the lateral torque.

[0035] The operator positions the device at the sampling point using the self-locking casters 21 at the bottom of the base plate 1, and uses the support feet 20 to stabilize it and prevent it from sinking. When the sampling work is completed, the operator holds the handle 24 and pries the entire device to move it in an inclined position using the self-locking casters 21.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
