Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil sampling, and in particular to a soil sampling device for soil remediation. Background Technology
[0002] Soil remediation is the process of removing or stabilizing pollutants in soil through physical, chemical, or biological techniques to restore its ecological functions. Soil sampling is a fundamental step before remediation. By collecting representative samples and analyzing the types, concentrations, and distribution characteristics of pollutants, data are provided to assess the degree of pollution and formulate remediation plans. To facilitate soil sampling, a soil sampling device for soil remediation is needed.
[0003] According to the Chinese patent "Soil Sampler" authorization announcement number "CN220602986U", this utility model, through the cooperation of parts such as soil sampling tube, fixing block, lifting component, pushing structure and driving mechanism, enables the device to seal the soil sampling tube by pushing structure when in use, until it is inserted into the sampling area at a certain depth at the bottom of the soil, and then the seal of the pushing structure is released to achieve deep sampling. This solves the problem that the existing devices can only sample the surface and have low practicality and great limitations.
[0004] Although the above application can achieve deep sampling by using a pushing mechanism in conjunction with the sealing of the soil sampling tube, allowing the sampling tube to descend to a certain depth, soil sampling usually requires sampling at different depths on the same piece of land. The above application can only sample soil at one depth at a time. If sampling at different depths is required, multiple samplings are needed, which is cumbersome and inefficient.
[0005] Therefore, a soil sampling device for soil remediation is proposed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a soil sampling device for soil remediation to solve the above-mentioned problems, thereby improving the inability to sample soil at different depths in a single operation.
[0007] This utility model achieves the above-mentioned objective through the following technical solution: a soil sampling device for soil remediation, comprising: a support frame, a first motor disposed on the inner side of the support frame, a drill bit disposed below the first motor, and a lifting assembly disposed on the inner wall of the support frame;
[0008] The sampling mechanism includes a drill rod fixedly connected between the drill bit and the drive end of the first motor. The surface of the drill rod has three sampling ports of the same height, and a baffle is slidably connected to the inner wall of the drill rod.
[0009] Preferably, the inner wall of the drill rod is fixedly connected to two partitions. These two partitions, together with the inner bottom wall of the drill rod, divide the drill rod into three chambers. The three sampling ports are distributed circumferentially around the drill bit, and the two partitions are positioned above the two upper sampling ports. This allows for the separate storage of soil samples from different depths, facilitating identification.
[0010] Preferably, a slider is slidably connected to the inner wall of the baffle, and a lever is fixedly connected to the surface of the slider. The lever passes through the drill rod, and the three baffles have different lengths. This facilitates the fixing of the baffles.
[0011] Preferably, the drill rod has a groove on its surface, the groove being an inverted "L" shape. This provides support for the drive motor and reduces the workload of the workers.
[0012] Preferably, a lifting plate is slidably connected to the surface of the support frame, and the first motor is fixedly connected to and passes through the lifting plate. Two through slots are formed on the surface of the lifting plate. This facilitates the movement of the device.
[0013] Preferably, the lifting assembly includes a lifting block fixedly connected to the inner wall of the lifting plate, and the support frame has sliding grooves on both sides inside. The lifting block is slidably connected to the sliding grooves, and a threaded rod is rotatably connected within the sliding grooves. The lifting block is disposed on the surface of the threaded rod. This indirectly drives the drill bit to rise and fall.
[0014] Preferably, a second motor is fixedly connected to the inner wall of the support frame, and the drive end of the second motor is fixedly connected to the top end of the threaded rod. A scale is provided on one side surface of the support frame for easy observation of the drill bit's descent depth.
[0015] The beneficial effects of this utility model are:
[0016] 1. By setting three chambers inside the drill rod, corresponding to three sampling ports, three storage spaces are formed inside the slide rod. With the help of baffles, the three sampling ports can be opened and closed. With the drill bit driving the drill rod to descend to different depths, soil samples can be taken at different depths in a single operation, avoiding the problem of repeated drilling and improving work efficiency.
[0017] 2. By setting up a support frame in conjunction with a lifting assembly, when taking samples, the staff only needs to fix the support frame to the ground. Then, the second motor drives the threaded rod to move the lifting platform up and down with the first motor, so that the drill bit can drill downwards. This eliminates the need for the staff to continuously stabilize the drill bit, reducing the workload of the staff and making the operation easier for them. Attached Figure Description

Detailed Implementation
[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] In practical implementation: such as Figure 1-5 As shown, a soil sampling device for soil remediation includes: a support frame 100, a first motor 210 disposed on the inner side of the support frame 100, a drill bit 500 disposed below the first motor 210, and a lifting assembly 300 disposed on the inner wall of the support frame 100.
[0026] The sampling mechanism 400 includes a drill rod 410 fixedly connected between the drill bit 500 and the drive end of the first motor 210. The surface of the drill rod 410 has three sampling ports 412 of the same height, and a baffle 420 is slidably connected to the inner wall of the drill rod 410.
[0027] like Figure 3 , Figure 4 and Figure 5As shown, two partitions 413 are fixedly connected to the inner wall of the drill rod 410. The two partitions 413, together with the inner bottom wall of the drill rod 410, divide the drill rod 410 into three chambers. The three sampling ports 412 are distributed in a circle with the drill bit 500 as the center. The two partitions 413 are set above the two sampling ports 412 located at the top. A slider 421 is slidably connected to the inner wall of the baffle 420. A lever 422 is fixedly connected to the surface of the slider 421. The lever 422 passes through the drill rod 410. The three baffles 420 have different lengths. A groove 411 is opened on the surface of the drill rod 410. The groove 411 is inverted "L" shape.
[0028] In this embodiment, the support frame 100 is in the shape of an inverted "U". Both inner walls of the support frame 100 are provided with grooves 340. One groove 340 is provided with only a lifting block 310, and the other groove 340 is provided with a threaded rod 320. The threaded rod 320 drives the lifting block 310 in the groove 340 to descend. The first motor 210 is provided in the protective shell. The support frame 100 is provided with a mudguard in the groove 340 on the side where the threaded rod 320 is provided. The mudguard passes through the lifting block 310 on that side. In order to prevent debris such as gravel and mud from affecting the threaded rod 320, the mudguard is provided with two partitions 413 respectively fixed above the two sampling ports 412 located above.
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a lifting plate 200 is slidably connected to the surface of the support frame 100. A first motor 210 is fixedly connected to the lifting plate 200 and passes through the lifting plate 200. Two through slots 220 are opened on the surface of the lifting plate 200. The lifting assembly 300 includes a lifting block 310 fixedly connected to the inner wall of the lifting plate 200. Slide grooves 340 are opened on both sides of the inside of the support frame 100. The lifting block 310 is slidably connected to the slide groove 340. A threaded rod 320 is rotatably connected in the slide groove 340. The lifting block 310 is disposed on the surface of the threaded rod 320. A second motor 330 is fixedly connected to the inner wall of the support frame 100. The drive end of the second motor 330 is fixedly connected to the top end of the threaded rod 320. A scale 110 is provided on one side surface of the support frame 100.
[0030] In this embodiment, when it is necessary to raise or lower the drill bit 500, the second motor 330 is started to drive the threaded rod 320 to rotate, thereby driving the lifting block 310 to rise or fall. The lifting block 310 drives the lifting platform and the first motor 210 to rise or fall. After the second motor 330 is started, the second motor 330 will drive the threaded rod 320 to rotate. The rotation of the threaded rod 320 will drive the lifting block 310 to move on the surface of the threaded rod 320 and slide along the slide groove 340, so that the lifting platform rises or falls.
[0031] When using this utility model, the support frame 100 of the device is fixed to the preset position, then the baffle 420 is lowered completely, the first motor 210 is started, the drill rod 410 and the drill bit 500 are rotated by the first motor 210, and then the second motor 330 is started to lower the lifting plate 200.
[0032] The drilling depth is determined by the scale 110 on the side of the support frame 100. After descending to the preset depth, the first motor 210 and the second motor 330 are turned off. A lever 422 on the baffle 420 corresponding to a sampling port 412 is selected. The lever 422 is pulled upward along the slot 411. After being pulled to the top of the slot 411, the lever 422 is moved to one side. The slider 421 slides within the baffle 420, causing the lever 422 to engage with the slot 411. At this time, the corresponding sampling port 412 is in the open state. Then, the first motor 210 is restarted, and the drill rod 4... 10. Rotate the motor to allow soil to enter the chamber corresponding to the sampling port 412. After sampling is completed at the sampling port 412, turn off the first motor 210 again. Use the lever 422 to reset the baffle 420 and then restart the first motor 210 and the second motor 330 to drive the drill bit 500 to drive the drill rod 410 to continue to penetrate deeper into the ground. Repeat the above operation to sample soil at different depths. When all sampling is completed, start the second motor 330 to rotate in the opposite direction, thereby raising the drill rod 410 and the drill bit 500. After they are fully raised, the soil sample inside the drill rod 410 can be taken out.
[0033] It should be noted that the first motor 210, the second motor 330, and the threaded rod 320 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the first motor 210, the second motor 330, and the threaded rod 320 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
