Description

Technical Field

[0001] This utility model relates to the field of geological testing and sampling technology, and more specifically, to an environmental geological testing and sampling device. Background Technology

[0002] Some factories need to treat their wastewater and exhaust gases before discharging them to avoid environmental pollution. However, some companies secretly discharge wastewater to save costs, which can pollute nearby rivers and, through infiltration, contaminate the surrounding soil. Therefore, environmental protection staff need to take soil samples from near factories from time to time to test whether the soil is contaminated.

[0003] The current method for soil testing and sampling involves a drilling rig rotating a hollow tube into the soil, pressing the soil into the hollow chamber. After sampling, the hollow tube is disassembled and the soil is removed, thus completing the soil sampling. However, in practice, the collected soil needs to be removed by disassembling the hollow tube into two pieces, which wastes time and affects work efficiency. Utility Model Content

Detailed Implementation

[0029] Example: Refer to Figures 1-6 This utility model provides a technical solution: an environmental geological testing and sampling device, including a support frame 1, and a control motor 2 is set on the support frame 1. A spiral drill rod 3 is set at the output end of the control motor 2. A sampling mechanism 4 is set outside the spiral drill rod 3. The sampling mechanism 4 includes a connecting seat 41, which is installed at the output end of the control motor 2. The bottom of the connecting seat 41 is connected to an annular plate 411 by bolts. A hollow cylinder 42 is fixedly installed at the bottom of the annular plate 411, and the spiral drill rod 3 is set inside the hollow cylinder 42. Several conical teeth 421 are also fixedly installed at the bottom of the hollow cylinder 42. A collection chamber 43 is stably installed inside the hollow cylinder 42.

[0030] In a preferred embodiment, two vertical rods 5 are fixedly installed on the support frame 1, and a sliding seat 6 is slidably connected to the vertical rods 5. A support frame 7 is fixedly installed on the outer surface of the sliding seat 6, and a control motor 2 is fixedly installed on the top of the support frame 7. A drive shaft 8 is stably installed at the output end of the control motor 2, and a connecting seat 41 is fixedly installed on the outer end of the drive shaft 8. The spiral drill rod 3 is welded to the drive shaft 8 for use. In this device, two vertical rods 5 are installed on the support frame 1 and set vertically. The sliding connecting plate on the sliding seat 6 is sleeved on the two vertical rods 5 to limit the sliding seat 6, so that the sliding seat 6 can move up and down stably during use. In this device, the support frame 7 is fixedly installed on the sliding seat 6 with bolts, and the control motor 2 is stably installed on the support frame 7. The drive shaft 8 passes through the interior of the support frame 7 and extends out of the interior of the support frame 7. The drive shaft 8 can be welded together with the spiral drill rod 3. The rotation of the drive shaft 8 can drive the spiral drill rod 3 to rotate, thereby entering the soil to stir and facilitate soil collection and sampling.

[0031] A rectangular plate 9 is fixedly installed on the outer surface of the support frame 1. A battery 10 is installed on the rectangular plate 9 and is electrically connected to the control motor 2. Since this equipment is used outdoors, the battery 10 is installed on the rectangular plate 9 to ensure that the equipment can be used normally. The battery 10 is electrically connected to the control motor 2 and the drive motor 13 respectively, so that the control motor 2 and the drive motor 13 can be used normally. The control motor 2 can be used to drive the hollow cylinder 42 and the spiral drill rod 3 to rotate. The drive motor 13 can drive the gear 12 to rotate and drive the chain 111 to move, so as to adjust the position of the hollow cylinder 42 and the spiral drill rod 3.

[0032] By setting several collection chambers 43 evenly inside the hollow cylinder 42 and placing them outside the auger rod 3, the collection chamber 43 consists of an arc-shaped end and an inclined end. The arc-shaped end is in direct contact with the inner wall of the hollow cylinder 42. The hollow cylinder 42 in this device is set as a hollow cylinder, and the collection chambers 43 are installed in a ring shape inside the hollow cylinder 42. During use, the auger rod 3 will drive the soil upward. During the movement, the rotation of the auger rod 3 will throw the soil off the rotating blades, allowing the soil to fall onto the inclined end. The soil will naturally slide into the arc-shaped end for collection. No matter how fast the hollow cylinder 42 rotates, the soil will not be thrown out, making soil collection convenient.

[0033] The device also has a drive mechanism 11 installed on the support frame 1. The drive mechanism 11 includes a chain 111 and a connecting plate 112. Gears 12 are installed at the top and bottom of the support frame 1, respectively. The two gears 12 are connected by the chain 111. A drive motor 13 is installed at the upper end of the support frame 1, and the gears 12 at the upper end of the support frame 1 are installed on the output end of the drive motor 13. There are two chains 111, both of which are installed on the support frame 1. The connecting plate 112 is stably installed on the two chains 111, and the connecting plate 112 is stably connected to the sliding seat 6.

[0034] This equipment installs a transmission rod at the output end of the drive motor 13. Two gears 12 are installed on one transmission rod, so that the drive motor 13 can control the rotation of the two gears 12 simultaneously. Chains 111 are installed on the two gears 12 respectively. Through the transmission of the chains 111, the rotation of the gear 12 at the bottom of the support frame 1 can be controlled. In this state, the chains 111 can rotate stably. In addition, the equipment installs a connecting plate 112 on the two chains 111. By moving the two chains 111 simultaneously, the connecting plate 112 can be moved, thereby driving the support frame 7 to move to meet the processing needs.

[0035] The device will also be equipped with rollers at the bottom to move it. In addition, to ensure the stability of the device during use, a screw will be installed at the bottom of the support frame 1. When the device is moved to the sampling area, the screw will be screwed into the soil to increase the stability of the support frame 1 and ensure stable soil sampling.

[0036] Specifically, an environmental geological testing and sampling device was designed in this context. Currently, the method for soil testing and sampling involves a drilling rig rotating a hollow tube into the soil, pressing the soil into the hollow chamber, and then disassembling the hollow tube and removing the soil after sampling. However, in practice, the hollow tube needs to be disassembled into two pieces before the soil can be removed, which wastes time and affects work efficiency.

[0037] This equipment is used for soil sampling near factories. The soil samples are then taken to a laboratory for testing to determine whether the soil near the factory is contaminated. The specific operation involves moving the equipment to the sampling area. Since the equipment has a built-in battery 10, it can be used directly without an external power source. Initially, the hollow cylinder 42 is not installed on the connecting seat 41. It is only installed after arriving at the site to prevent the auger rod 3 from impacting the inner wall of the hollow cylinder 42 during transportation and damaging the auger blades on the auger rod 3.

[0038] After being transported to the site, the hollow cylinder 42 is installed on the connecting seat 41 using bolts. The installation of the hollow cylinder 42 can be completed simply by connecting the annular plate 411 and the connecting seat 41 with bolts. Then, the spiral drill rod 3 is driven to rotate by the control motor 2. Since the hollow cylinder 42 is also stably installed on the output end of the control motor 2, the spiral drill rod 3 and the hollow cylinder 42 can rotate simultaneously. Then, the drive motor 13 drives the gear 12 to rotate. The rotation of the gear 12 drives the chain 111 to rotate downward, which can drive the sliding seat 6 to move downward and drive the hollow cylinder 42 and the spiral drill rod 3 to move upward together.

[0039] Since the auger rod 3 is located inside the hollow cylinder 42, the hollow cylinder 42 is the first part to come into contact with the ground. The conical teeth 421 on the bottom of the hollow cylinder 42 rotate on the ground, which can rotate the hollow cylinder 42 into the soil. Then the auger rod 3 will also rotate into the soil inside the hollow cylinder 42. The spiral blades on the auger rod 3 rotate upward, which can drive the soil upward. Under the rapid rotation of the spiral blades, the soil is thrown into the collection chamber 43. The collected soil is collected by the collection chamber 43. The soil will move to the arc-shaped end of the collection chamber 43. Even when the hollow cylinder 42 rotates rapidly, the soil inside the collection chamber 43 will not be thrown out.

[0040] After soil collection, the hollow cylinder 42 and the spiral drill rod 3 are lifted upwards, and the control motor 2 and drive motor 13 are turned off. Then, the bolts on the annular plate 411 are unscrewed, and the hollow cylinder 42 is disassembled from the connecting seat 41. The soil collected inside the collection chamber 43 can be poured out, completing the soil sampling. This equipment effectively replaces the traditional method of disassembling the sampling tube into two pieces for soil collection, saving time and improving work efficiency.
