Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and more particularly to a soil sampling device for environmental protection engineering. Background Art

[0002] In environmental protection projects, soil testing is of great significance. By testing and sampling the soil, we can evaluate the physical and chemical properties of the soil, the content of pollutants and other information, understand the quality of the soil, and provide basic data for environmental monitoring and evaluation.

[0003] The Chinese patent application with publication number CN117705492A proposes a soil sampling structure and a soil detection device. By arranging a cleaning component on a mobile base, a driving member can drive the harrow wheel to rotate while reciprocating, so that it can roll and scrape against the surface of the ground to achieve the purpose of cleaning the debris on the soil surface. Then, the upper barrel is moved downward and the spiral rod is rotated to autonomously drill the soil into the storage chamber.

[0004] Although the above patent can play a certain role in removing impurities when collecting soil samples, it still has shortcomings in the actual large-scale and multi-point sampling work:

[0005] In order to more comprehensively reflect the soil conditions in a certain area, it is often necessary to set up multiple sampling points and take multiple soil samples for comparison and testing in actual operations, that is, multiple collection work is required. However, the existing equipment lacks the means to clean the sampling site in the intervals between continuous collection work, which can easily cause the soil sample collected last time to adhere to the sampling site and mix into the soil sample collected next time, thus causing certain errors. Summary of the invention

[0006] The invention provides a soil sampling device for environmental protection engineering, which solves the technical problem of sampling errors caused by lack of cleaning means for sampling parts during the intervals of continuous sampling work.

[0007] The present invention provides a soil sampling device for environmental protection engineering, comprising a mobile module, on which a drilling module, a screening module and a material receiving box are arranged, the mobile module drives the device to move to a sampling position, the drilling module drills soil samples, and the soil samples fall into the material receiving box after being vibrated and screened by the screening module, and a cleaning module is provided on the drilling module;

[0050] When the main shaft rotates, the second guide tube rotates around the annular groove through the connection of the clamping plate, and at the same time, the contact between the top column and the adjusting tube drives the second guide tube to reciprocate up and down relative to the clamping plate.

[0055] The present invention constructs a direct flushing cleaning method that relies on the water liquid spraying action on the drilling module, which can flush away the soil sample adhering to the surface of the drilling module when taking materials. In this action, the reciprocating driving member also combines the control action of the second guide tube, so that the second guide tube can perform up and down reciprocating action while rotating around the center of the drilling module.

When water fills the cavity between the mask and the drilling module, ultrasonic vibration is generated by the ultrasonic vibration head to vibrate and clean the drilling module. The cleaning action here can remove some soil samples contaminated by details that are difficult to remove by flushing in the first action. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0079] like Figure 1 - Fig.10 As shown, a soil sampling device for environmental protection engineering includes a mobile module 1, on which a drilling module 2, a screening module 3 and a material receiving box 4 are arranged. The mobile module 1 drives the device to move to a sampling position, and the drilling module 2 drills soil samples, which fall into the material receiving box 4 after being vibrated and screened by the screening module 3. The drilling module 2 is equipped with a cleaning module 5;

[0080] refer to Figure 4 The cleaning module 5 includes a mask 500, which is covered on the outside of the drilling module 2. A first conduit 520 is connected to the output end of the water supply member 510, and a second conduit 530 extends into the drilling module 2. A telescopic tube 540 is connected between the second conduit 530 and the first conduit 520. A nozzle 531 is provided on the second conduit 530, and sprays water delivered by the water supply member 510 to flush and clean the drilling module 2. A reciprocating driving member 550 is matched between the second conduit 530 and the drilling module 2 to drive the second conduit 530 to rotate around the center of the drilling module 2 and to reciprocate and rise and fall. An ultrasonic vibration head 560 is matched at the bottom of the mask 500. When the water output by the water supply member 510 fills the cavity between the mask 500 and the drilling module 2, the ultrasonic vibration head 560 generates ultrasonic vibration to vibrate and clean the drilling module 2.

[0081] Compared with the traditional sampling device, the present invention has two cleaning methods. The first one is the above-mentioned direct flushing cleaning method that relies on the water liquid spraying into the drilling module 2, which can flush away the soil sample adhering to the surface of the drilling module 2 when taking materials. In this action, the reciprocating drive member 550 also controls the action of the second guide tube 530, so that the second guide tube 530 can reciprocate up and down while rotating around the center of the drilling module 2. The rotation allows the flushing range to cover the entire spiral blade 250. The up and down reciprocating action allows the liquid level sprayed by the nozzle 531 to swing up and down during the flushing action, covering the upper and lower parts of the spiral blade 250, so that the soil sample covering the surface of the spiral blade 250 can be fully flushed out;

[0082] In the second cleaning method, when the water fills the cavity between the mask 500 and the drilling module 2, the ultrasonic vibration head 560 generates ultrasonic vibration to vibrate and clean the drilling module 2. The cleaning effect here can remove some soil samples contaminated by the first effect that are difficult to be removed by flushing.

[0083] After the double cleaning action, the soil sample in the drilling module 2 is mixed in the cleaning water and discharged together by opening the bottom cover 505. Then, when in use, the drilling module 2 can be dried by an additional hot air drying action to reduce the processing interval time during continuous sampling.

[0084] In the above, the present invention constructs a cleaning method with a comprehensive scope of action and an action level from the whole to the local. In the intervals between continuous collection work, the residues of the soil samples collected last time in the drilling module 2 can be effectively removed to prevent them from being mixed into the soil samples collected next time, thereby improving the accuracy of actual sampling and adapting to the actual sampling work of multiple collections.

[0085] refer to Figure 4 , Figure 5 and Figure 6 The drilling module 2 includes a slide rail 200, which is fixed on the mobile module 1. The slide seat 210 is slidably connected to the slide rail 200. The first linear drive member 220 drives the slide seat 210 to slide up and down relative to the slide rail 200. The drilling motor 230 is fixed on the slide seat 210. The main shaft 240 is fixedly connected to the output end of the drilling motor 230. The spiral blade 250 is fixed on the main shaft 240. The sleeve 260 is fixed on the mobile module 1. The sleeve 260 is sleeved on the outside of the spiral blade 250. When cleaning, the second guide tube 530 is inserted into the gap between the inner wall of the sleeve 260 and the spiral blade 250. The discharge member 270 is arranged on one side of the top of the sleeve 260.

[0086] When drilling soil samples, the first linear drive member 220 drives the slide 210 to slide downward relative to the slide rail 200 until the bottom of the spiral blade 250 contacts the ground. Then the drilling motor 230 starts to drive the main shaft 240 and the spiral blade 250 to rotate and drill the soil sample downward. The drilled soil sample rises along the spiral blade 250 and is output from the discharge member 270 to the side of the screening module 3.

[0087] refer to Fig.10 The discharge member 270 includes an inner base 2700, which is fixed on the sleeve 260, an extension portion 2720 is connected between the outer base 2710 and the inner base 2700, a connecting strip 2730 is fixed on the outer base 2710, a linear telescopic member 2740 is fixed on the sleeve 260, and an output end of the linear telescopic member 2740 is fixedly connected to the connecting strip 2730.

[0088] When drilling soil samples, the linear telescopic member 2740 drives the outer base 2710 away from the inner base 2700, and the extension part 2720 is extended accordingly, so that the soil sample output from the port of the outer base 2710 can fall into the screening module 3. When cleaning, the linear telescopic member 2740 drives the outer base 2710 close to the inner base 2700, and the extension part 2720 is shortened accordingly, so that the port of the outer base 2710 is within the coverage range of the mask 500.

When the hammer block 340 is driven to rotate by the vibration motor 330, the material frame 300 vibrates with the spring 350.

[0090] The drilled soil sample is output from the discharge piece 270 and falls into the material frame 300 of the screening module 3. Under the eccentric action of the hammer block 340 driven by the vibration motor 330 and the non-rigid connection provided by the spring 350, the material frame 300 vibrates, and impurities such as stones and plant roots in the soil sample are retained above the screen 310 under the action of vibration screening.

When cleaning is performed, the bottom cover 505 is closed, the upper ring body 501 and the lower ring body 502 are separated, and the folding part 503 is unfolded to form a shield for the drilling module 2 as a whole.

[0093] refer to Figure 8 Furthermore, an electric hinge 506 is provided between the bottom cover 505 and the lower ring body 502, so that the opening and closing of the bottom cover 505 can be performed automatically.
