Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a soil detection device for environmental detection. Background Art

[0002] Environmental testing refers to the means of quantitatively analyzing the content, properties and environmental impact of various substances in the environment, which includes testing of air, water, soil, noise and other aspects. Among the soil, sampling of mountain soil is one of the ways to detect the ecological environment, and it can also prevent landslides.

[0003] The existing detection of mountain soil generally adopts the method of drilling sampling. The working principle of this method is: first use a hollow drill to drill a hole in the ground, and then the staff will insert the sampling equipment into the "soil column" drilled by the hollow drill, and the sampling equipment will move the "soil column" to the equipment that needs to analyze the soil properties, so as to complete the soil detection. However, when using the drilling equipment to drill a hole in the mountain, in order to intuitively observe the vertical profile of the soil, the drilling equipment needs to be kept perpendicular to the slope of the mountain.

[0004] When drilling a mountain with a large slope, since the soil itself has a certain weight, as the drilling depth gradually increases, the weight of the soil above will exert pressure on the drilling equipment, causing deviations in the drilling position and affecting the drilling slope, ultimately affecting the accuracy of soil sampling and testing. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In order to solve the problem that when the existing drilling equipment is drilling a mountain with a large slope, the soil in the mountain will continue to exert pressure on the drilling equipment, thereby causing deviation in the drilling position and even affecting the drilling slope, the present invention adopts a method of adding a "blocking member" to simulate a shovel inserted into the soil, providing pre-support for the soil on the upper side of the drilling equipment, so that during the drilling process of the drilling equipment, the soil on the upper side of the drilling equipment can be supported to the position before drilling, thereby preventing the soil on the upper side of the drilling equipment from affecting the drilling direction of the drilling equipment due to its own pressure problem, causing the layered structure of the soil to be destroyed.

A guide member 108 is fixedly connected to the left side of the baffle 107, and a cutting rod 109 is slidingly connected to the left side of the guide member 108. The lower side of the cutting rod 109 is slidingly matched with the baffle 107. A pad 2 is fixedly connected to the lower side of the guide member 108. The lower side of the pad 2 is located in the same horizontal plane as the lower side of the mounting frame 101. The "triangular fixing frame" composed of the cutting rod 109, the baffle 107 and the guide member 108 is used to increase the stability of the structure. Under the action of the pad 2 fitting the soil, the fixing degree of the soil is improved. A first fixing component for fixing the cutting rod 109 is provided on the baffle 107, and a cutting component for cutting plant roots is provided on the rotating drum 106.

[0038] like Figure 2 and Figure 4As shown, the first fixed component includes a first liquid guide member 300 fixedly connected to the lower inner side of the baffle 107, a first sliding member 301 is slidably connected in a sealed position in the first liquid guide member 300, the lower side of the first sliding member 301 is not sealed with the first liquid guide member 300, the lower side of the first sliding member 301 is slidably limited with the lower side of the cutting rod 109, a second liquid guide member 302 is fixedly connected to the left side of the baffle 107, the second liquid guide member 302 is located above the pad 2, a second sliding member 303 is slidably connected in a sealed position in the second liquid guide member 302, the left side of the second sliding member 303 is not sealed with the second liquid guide member 300, and the second liquid guide member 303 is slidably limited with the left side of the second liquid guide member 303. The liquid guiding member 302 is sealed, and a connecting pipe for connecting the second liquid guiding member 302 and the first liquid guiding member 300 is fixedly connected in the baffle 107. Hydraulic oil is stored in the second liquid guiding member 302, the first liquid guiding member 300 and the connecting pipe connecting the two. The cutting rod 109 is fixed by moving the first sliding member 301 downward. The left side of the sliding frame 102 is detachably connected to the fixed cylinder 4, which is made of biodegradable material. The central axis of the fixed cylinder 4 coincides with the central axis of the rotating cylinder 106. The right side of the fixed cylinder 4 is provided with through holes that are mirror images front and back and distributed in a linear array.

[0039] like Figure 5 , Figure 7 and Figure 8 As shown, the cutting assembly includes a rotating ring 401 rotatably connected to the lower side of the rotating drum 106, a torsion spring is fixedly connected between the rotating ring 401 and the rotating drum 106, the upper sides of the fixed teeth 1061 distributed in an annular array are fixedly connected to the rotating ring 401, and the lower side of the rotating drum 106 is fixedly connected with cutting knives 402 distributed in an annular array, and the cutting knives 402 are used to cut the roots of plants. The number of cutting knives 402 is consistent with the number of fixed teeth 1061, and the cutting knives 402 are slidably matched with adjacent fixed teeth 1061. When the cutting knives 402 slide out of the adjacent fixed teeth 1061, the roots of surrounding plants are cut.

[0040] Before sampling and testing a mountain with a large slope, the staff will first level the area where sampling and testing is required, and then the staff will pull out the insertion rod 109 until it is no longer in contact with the baffle 107. Finally, the staff will insert the baffle 107 into the leveled area (the insertion position of the baffle 107 is toward the higher side of the mountain). During the movement of the baffle 107 toward the leveled area, it drives the mounting frame 101 and its accessories to move downward.

[0041] When the lower side of the mounting frame 101 moves to fit the soil in the leveled area, the lower side of the pad 2 has been in contact with the soil in the leveled area, and then the staff inserts the implantation rod 109 into the guide member 108. During the downward movement of the implantation rod 109, it penetrates the soil and gradually inserts into the lower side of the baffle 107.

[0042] When the cutting rod 109 is inserted into the lower side of the baffle 107, the cutting rod 109 is fitted with the upper side of the guide member 108, and then the staff presses the second sliding member 303. During the movement of the second sliding member 303, the hydraulic oil in the second liquid guide member 302 is squeezed into the first liquid guide member 300 through the connecting pipe. After the pressure in the first liquid guide member 300 increases, the first sliding member 301 moves downward and is inserted into the lower side of the cutting rod 109, so as to fix the cutting rod 109, so that the cutting rod 109, the baffle 107 and the guide member 108 are fixed. 8 forms an integral "triangular fixing frame", and the contact between the baffle plate 107 and the soil provides pre-support for the subsequent drilling process, preventing the soil on the upper side of the drilling area from affecting the drilling direction of the drilling equipment due to its own pressure problem, causing the layered structure of the soil to be destroyed, and the "triangular fixing frame" composed of the cutting rod 109, the baffle plate 107 and the guide member 108 improves the stability of the structure, and the fixation of the soil is improved under the action of the pad 2 fitting with the soil, thereby completing the preparation action before drilling the soil.

[0043] After completing the preparations before drilling a hole in the soil, the staff starts the motor 105. The driving shaft of the motor 105 drives the rotating drum 106 to rotate through the pulley belt. The rotating drum 106 drives the fixed teeth 1061 distributed in a circular array to rotate. Then the staff rotates the hand crank 104. The hand crank 104 drives the threaded rod 103 to rotate, so that the sliding frame 102 drives the rotating drum 106, the fixed drum 4 and its accessories to move downward along the mounting frame 101. The rotating drum 106 indirectly drives the fixed teeth 1061 distributed in a circular array and its accessories to rotate through the adjacent torsion springs and the rotating ring 401. During this process, the spiral cutter on the outside of the rotating drum 106 drills into the soil to drill a hole in the soil.

[0044] The rotating drum 106 drives the fixed drum 4 to move in the process of moving downward. The rotating drum 106 and the outer spiral cutter rotate, and the soil is introduced into the fixed drum 4 and guided out through all the through holes on the rear side thereof, so as to achieve the processing of excess soil.

[0045] When the rotating drum 106 indirectly drives the annular array distributed fixed teeth 1061 to rotate through the adjacent torsion springs and the rotating ring 401 and encounters an obstacle (the root system of the plant), the annular array distributed fixed teeth 1061 are stuck in the root system of the plant. At this time, the rotation of the rotating drum 106 drives the annular array distributed cutting knife 402 to rotate (the annular array distributed fixed teeth 1061 cannot rotate, so the rotation of the rotating drum 106 drives the adjacent torsion springs to be gradually tightened), so that the cutting knife 402 is protruded from the adjacent fixed teeth 1061. The protruding cutting knife 402 cuts the root system of the plant to prevent the root system of the plant from jamming the annular array distributed fixed teeth 1061 and preventing it from continuing to drill into the soil.

[0046] After the cutting of the plant root system is completed, the fixed teeth 1061 distributed in the annular array return to slide under the action of the adjacent torsion springs.

[0047] When the depth of the borehole meets the required depth for the work, the staff turns off the motor 105 and stops rotating the hand crank 104, so as to stop drilling into the soil. The staff then inserts the sampling equipment into the "soil column" drilled by the present invention, intercepts the "soil column", and then takes out the "soil column" for further processing.

[0048] After the staff takes out the "soil column", the staff removes the fixed cylinder 4, and then the staff reverses the hand crank 104, which drives the threaded rod 103 to rotate, so that the sliding frame 102 drives the rotating cylinder 106 and its accessories to move upward, thereby gradually leaving the drilling area.

[0049] When the rotating drum 106 is separated from the drilling area, the drilling area is fixed by the fixing drum 4 to prevent the drilling area from collapsing after the "soil column" is taken out, thereby affecting the structure of the mountain.

[0050] After completing the drilling of the soil, the staff first pulls the second sliding member 303 to the left to reduce the pressure of the hydraulic oil in the second liquid guiding member 302, thereby moving the first sliding member 301 upward to release the limit on the cutting rod 109, and then the staff slowly pulls out the cutting rod 109, and finally the staff pulls out the baffle 107, the mounting frame 101 and its accessories upward.

[0051] When the existing sampling equipment takes out the sample, since the part of the sampling equipment located in the soil is still connected to the soil, when the sample is taken out from the soil, the continuity of the sample, the soil profile and the compactness of the soil will all change, which will not only cause the soil stratification to be destroyed, but also cause the soil to become loose and collapse, and the above-mentioned changes will affect the results of soil detection. To solve the above problems, the present invention adopts a method of internally truncating the sampled "soil column" inside the soil, disconnecting the part of the soil to be sampled from the soil, and sealing the lower side of the sampled soil to prevent the "soil column" from becoming loose and collapsing due to the hollowing out of the lower side during the process of taking out the "soil column".

[0052] Embodiment 2: Based on embodiment 1, Figure 3 and Figure 6-Figure 12As shown, a sampling assembly for separating soil is also included. The sampling assembly is arranged in the rotating drum 106. The sampling assembly includes a one-way bearing 501 fixedly connected to the inner lower side of the rotating drum 106. The one-way bearing 501 is composed of an inner ring and an outer ring that rotate with each other. The outer ring of the one-way bearing 501 is fixedly connected to the inner lower side of the rotating drum 106. When the rotating drum 106 rotates clockwise, the outer ring and the inner ring of the one-way bearing 501 rotate with each other. When the rotating drum 106 rotates counterclockwise, the outer ring of the one-way bearing 501 drives the inner ring to rotate. The one-way bearing 501 is located above the rotating ring 401. The upper side of the one-way bearing 501 is splined with a first rotating member 502. The inner ring of the one-way bearing 501 and the first rotating member 502 are connected. The first rotating member 502 is splinedly connected and limitedly rotated to be connected to the first connecting member 503 located on the lower inner side of the rotating drum 106; the upper side of the first connecting member 503 is threadedly connected to the first sampling shell 504 and the second sampling shell 505; the first sampling shell 504 and the second sampling shell 505 are hinged; the first sampling shell 504 and the second sampling shell 505 are both located in the rotating drum 106; in the process of sampling the soil, the first sampling shell 504 and the second sampling shell 505 enter the soil synchronously with the rotating drum 106; the upper sides of the first sampling shell 504 and the second sampling shell 505 are commonly threadedly connected to the second connecting member 506; a cutting component for cutting off the "soil column" is arranged in the first connecting member 503.

[0056] Before drilling into the mountain soil and when the baffle 107 has been inserted into the soil, the staff rotates the two second rotating members 602 in sequence to make the two second rotating members 602 drill into the surrounding soil to enhance the stability of the mounting frame 101. After the second rotating members 602 drill into the required depth for work, the staff presses the two third sliding members 604 in sequence. During the movement of the third sliding members 604, the hydraulic oil in the adjacent third liquid guiding members 603 is squeezed into the adjacent fourth liquid guiding members 605 through the adjacent connecting pipes, so that the fourth sliding members 606 located in the fourth liquid guiding members 605 and distributed in a circular array move backward. The backward movement of the fourth sliding members 606 distributed in the circular array in the soil further enhances the stability of the mounting frame 101.

[0057] After the fixing of the mounting frame 101 is completed, the staff first swings the limiting rod 701 and the connecting plate 702 to not block the upper side of the rotating drum 106, and then the staff inserts the first rotating member 502, the first connecting member 503, the first sampling shell 504, the second sampling shell 505, the second connecting member 506 and its accessories into the rotating drum 106, so that the lower side of the first rotating member 502 is inserted into the spline groove in the upper inner ring of the one-way bearing 501, and then the staff rotates the limiting rod 701 and the connecting plate 702, and the connecting plate 702 drives the third rotating member 703 to rotate and make its central axis coincide with the central axis of the second connecting member 506, and finally the staff rotates the third rotating member 703, so that the third rotating member 703 moves downward along the connecting plate 702 and contacts the upper side of the second connecting member 506, thereby fixing the second connecting member 506 and its accessories (the above process is the preparation action before soil sampling).

[0058] After completing the preparations for soil sampling, the motor 105 drives the rotating drum 106 to rotate through the pulley belt, and the staff shakes the hand crank 104 to make the sliding frame 102 drive its attached parts to move downward to realize the drilling of the soil. As the drilling hole gradually goes deeper, the "soil column" gradually enters between the first sampling shell 504 and the second sampling shell 505 from the guide cylinder 5091.

[0059] When the drilling depth of the rotary drum 106 meets the depth required for the work, the motor 105 no longer drives the rotary drum 106 to rotate through the pulley belt, and the staff no longer shakes the hand crank 104. Then the staff controls the motor 105 to drive the rotary drum 106 to rotate in the opposite direction through the pulley belt. During the reverse rotation of the rotary drum 106, the one-way bearing 501 drives the first rotating member 502 to rotate, and the first rotating member 502 rotates along the first connecting member 503. During the rotation of the first connecting member 503, the inclined grooves distributed in the circular array on it squeeze the adjacent sliding plates 508 respectively, so that the sliding plate 508 drives the adjacent cutting knife 509 to slide upward, and when the cutting knife 509 slides to the exit edge between the guide cylinder 5091 and the first connecting member 503, the "soil column" in the middle of the guide cylinder 5091 is actively cut off.

[0060] When the first rotating member 502 rotates to the point where the lower side of the sliding plate 508 contacts the upper side of the adjacent chute on the first rotating member 502 (at this time, the staff no longer controls the motor 105 to rotate, and the rotating drum 106 no longer rotates), all the cutting knives 509 are in a Fig.12The state in the middle (the gravity provided by the "soil column" is not enough to bend all the cutting knives 509), so as to cut off all the "soil columns", thereby realizing active faulting of the "soil column", and supporting the lower side of the "soil column" through the close proximity of the annular array cutting knives 509, to prevent the "soil column" from becoming loose and collapsing due to the hollowing out of the lower side during the removal process.

[0061] After the "soil column" is cut off, the staff rotates the hand crank 104 in the reverse direction, so that the hand crank 104 drives the threaded rod 103 to rotate, thereby lifting the sliding frame 102 and the attached parts upward.

[0062] When the sliding frame 102 and its accessories are lifted to the ground, the staff rotates the third rotating member 703 in the opposite direction so that the third rotating member 703 no longer squeezes the upper side of the second connecting member 506, and then the staff swings the limit rod 701 and the connecting plate 702 to not block the upper side of the rotating drum 106, and then the staff pulls out the second connecting member 506 to the lower side of the first rotating member 502 so that it is no longer connected to the inner ring spline on the one-way bearing 501, and finally the staff rotates the second connecting member 506 and the first connecting member 503 to not contact the first sampling shell 504 and the second sampling shell 505, and then the staff takes out the "soil column" in the first sampling shell 504 and the second sampling shell 505.

[0063] After taking out the "soil columns" in the first sampling shell 504 and the second sampling shell 505, the staff rotates the first sampling shell 504 and the second sampling shell 505 again until they contact and limit the two ends of the first sampling shell 504 and the second sampling shell 505, and then the staff rotates the first rotating member 502 in the opposite direction, so that the first rotating member 502 drives all the sliding plates 508 and the cutting knives 509 to retract between the guide cylinder 5091 and the first connecting member 503.

[0064] After the staff completes the soil inspection, the staff pulls the third sliding member 604 upwards. During the movement of the third sliding member 604, the pressure of the hydraulic oil in the adjacent fourth liquid guiding member 605 is reduced, and then the fourth sliding members 606 distributed in the ring array move toward each other to break contact with the soil. Then the staff reversely rotates the second rotating member 602 to gradually break contact with the soil. Finally, the staff moves the mounting frame 101 out of the inspection area.

[0065] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention.
