[0031] Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a method for using a construction engineering sampling device. Through the method for using the construction engineering sampling device, the surface cleaning mechanism 200 cleans the soil surface, and then the soil brush cleaning mechanism 300 and the discharge mechanism 400 are used to clean the surface of the sampling sleeve 103 during the resetting process and discharge the soil sample.

[0032] When the user activates the soil sampling device 100 to drive the sampling sleeve 103 to move downward, the sampling sleeve 103 activates the surface cleaning mechanism 200 to clean the dead branches and fallen leaves on the soil surface; When the soil is collected into the sampling sleeve 103 and the soil sampling device 100 is started to drive the sampling sleeve 103 to move upward, the soil brushing and cleaning mechanism 300 is started to clean the outer surface of the sampling sleeve 103; When the sampling sleeve 103 continues to move upward, the discharge mechanism 400 is activated to insert into the sampling sleeve 103 and push out the soil sample in the sampling sleeve 103 .

[0033] Reference Figures 1 to 7 , which is the second embodiment of the present invention, provides a construction engineering sampling device, which uses a soil brushing and cleaning mechanism 300 to clean the soil attached to the surface of the sampling sleeve 103 during the resetting process of the sampling sleeve 103.

[0034] The soil brushing cleaning mechanism 300 includes a soil brushing half ring 301, which is located at the bottom of both sides of the impact machine 101. The bottom of the first sleeve 201 and the bottom of the second sleeve 202 are both connected to the exhaust pipe 302. The exhaust pipe 302 is slidably connected to the inside of the piston rod 303. The inner side of the piston rod 303 is fixedly connected to the outer side of the soil brushing half ring 301. Rainwater utilization components 304 are fixed on both sides of the top of the impact machine 101.

[0035] The rainwater utilization component 304 includes a water receiving tray 304a, the bottom of which is fixedly connected to both sides of the top of the impact machine 101, the inner side of the bottom of the water receiving tray 304a is connected to a water receiving hose 304b, the other end of the water receiving hose 304b passes through both sides of the bottom of the impact machine 101 and is connected to the top of the soil brushing half ring 301, the inner side of the inner wall of the soil brushing half ring 301 is provided with seepage holes 304c, a number of seepage holes 304c are provided and are distributed in an arc shape at equal distances, the bottom of the right side of the first sleeve 201 and the bottom of the left side of the second sleeve 202 are fixedly connected with a tight sealing member 304d, the inner side of the tight sealing member 304d is in close contact with the bottom of the outer side of the water receiving hose 304b, and the bottom of the impact machine 101 is fixedly connected with a washing and scraping component 304e.

[0036] The washing and scraping component 304e includes a water receiving ring 304e-1, the top of the water receiving ring 304e-1 is fixedly connected to the bottom of the impact machine 101, the bottom of the inner side of the water receiving hose 304b is connected to a diverter pipe 304e-2, the other end of the diverter pipe 304e-2 is connected to the outer side of the water receiving ring 304e-1, the inner wall of the water receiving ring 304e-1 is provided with a flushing groove 304e-3, and a plurality of flushing grooves 304e-3 are provided and distributed in a circular shape at equal distances, and the bottom of the water receiving ring 304e-1 is fixedly connected to a scraping ring 304e-4.

[0037] Specifically, when the sampling sleeve 103 and the blade 104 move upward and retract, the soil attached to the surface of the sampling sleeve 103 will be brushed off by the soil brushing half ring 301. If it rains, rainwater will drip into the water receiving tray 304a, and then the rainwater in the water receiving tray 304a will flow to the water receiving hose 304b for storage, and will not flow to the surface of the sampling sleeve 103 through the seepage hole 304c during the cleaning process of the sampling sleeve 103, further softening the soil on the surface of the sampling sleeve 103, and cooperating with the soil brushing half ring 301 to wash, thereby improving the cleaning effect. At the same time, part of the water will flow out through the flushing groove 304e-3 and wet the partially uncleaned soil on the surface of the sampling sleeve 103 and drive the cleaning downward during the flowing of water. Then, the scraper ring 304e-4 can be used to scrape off the mud and water remaining on the surface of the sampling sleeve 103, further improving the cleaning effect of the surface of the sampling sleeve 103.

[0038] Furthermore, after the soil to be sampled enters the sampling sleeve 103, the user activates the impact machine 101 to retract the movable rod 105, and then the movable rod 105 drives the sampling sleeve 103 and the blade 104 to move upward and retract. At this time, the transmission rope 205 stops transmitting the piston disc 203, and then the piston disc 203 is driven by the tension of the first tension spring 204 to move downward and reset, so that the piston disc 203 discharges the air inside the first sleeve 201 and the second sleeve 202 downward, and then the discharged air The air will enter the exhaust pipe 302, and driven by the air flow, it will push the piston rod 303 to move inward, so that the piston rod 303 pushes the soil brushing half ring 301 to move inward and fit. At this time, during the upward movement of the sampling sleeve 103, the soil attached to the surface of the sampling sleeve 103 will be brushed off by the soil brushing half ring 301, thereby cleaning the soil attached to the surface of the sampling sleeve 103. If it rains, rainwater will drip into the water receiving tray 304a, and then the rainwater in the water receiving tray 304a will flow to the water receiving hose 304. b is stored, and when the soil-brushing half ring 301 moves inward, it drives the water receiving hose 304b to move inward, so that the water receiving hose 304b is no longer in close contact with the tight sealing member 304d, so that the rainwater inside the water receiving hose 304b can continue to flow downward, thereby being guided to the inside of the soil-brushing half ring 301 and flowing to the surface of the sampling sleeve 103 through the seepage hole 304c, further softening the soil on the surface of the sampling sleeve 103, and cooperating with the soil-brushing half ring 301 to wash, thereby improving the cleaning effect, and In the process of entering the soil-brushing half ring 301, part of the rainwater will flow into the inner wall of the water receiving ring 304e-1 through the diversion pipe 304e-2, and flow out through the flushing groove 304e-3 opened on the water receiving ring 304e-1 and flow to the surface of the sampling sleeve 103, so that part of the uncleaned soil can be wetted and driven downward for cleaning during the flow of water. Then, the scraping ring 304e-4 can be used to scrape off the mud and water remaining on the surface of the sampling sleeve 103, further improving the cleaning effect of the surface of the sampling sleeve 103.

[0039] Reference Figures 1 to 7 , which is the third embodiment of the present invention, provides a construction engineering sampling device, through the soil brushing and cleaning mechanism 300, when the sampling sleeve 103 continues to move upward, the discharge mechanism 400 will be started to insert into the sampling sleeve 103 and limit the soil sample inside the sampling sleeve 103, so that when the sampling sleeve 103 continues to move upward driven by the impact machine 101, the soil can gradually separate from the sampling sleeve 103 and fall out.

[0040] The discharge mechanism 400 includes a slide rail 401, and an insert block 402 is slidably connected inside the slide rail 401. The top and bottom of the insert block 402 are inclined. A slot 403 is provided on the back of the sampling sleeve 103. A second tension spring 404 is fixedly connected to the top of the front side of the insert block 402, and the other end of the second tension spring 404 is fixedly connected to the front side of the inner wall of the slide rail 401.

[0041] Specifically, when the insert block 402 corresponds to the slot 403 on the sampling sleeve 103, the insert block 402 will be inserted into the soil inside the sampling sleeve 103. At this time, the soil will be limited by the insert block 402 and cannot move upward. When the sampling sleeve 103 continues to move upward driven by the impact machine 101, the soil can gradually separate from the sampling sleeve 103 and fall out. At this time, the user can place the collection bag under the sampling sleeve 103 to collect the soil, thereby preventing the removed soil from being contaminated.

[0042] Furthermore, as the cleaned sampling sleeve 103 continues to be driven upward by the impact machine 101, the top and bottom of the plug block 402 are both inclined, so that the plug block 402 will push the plug block 402 to move backward after contacting the rear side of the top of the sampling sleeve 103, and the second tension spring 404 will be pulled to further generate tension. When the plug block 402 corresponds to the slot 403 on the sampling sleeve 103, the plug block 402 will be inserted into the soil inside the sampling sleeve 103. At this time, the soil will be limited by the plug block 402 and cannot move upward. As the sampling sleeve 103 continues to move upward driven by the impact machine 101, the soil can gradually separate from the sampling sleeve 103 and fall out. At this time, the user can place the collection bag under the sampling sleeve 103 to collect the soil, thereby avoiding contamination of the removed soil.

[0043] The remaining structure is the same as that of Example 2.

[0044] Reference Figures 1 to 7 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a construction engineering sampling device.

[0045] First, the support frame 102 is used to support the impact machine 101 at the soil sampling location, and then the impact machine 101 is started to push the movable rod 105 downward, and then the movable rod 105 will push the sampling sleeve 103 and the blade 104 downward. During the ejection process, the sampling sleeve 103 will pull the transmission rope 205, so that the transmission rope 205 pulls the piston disc 203 in the first sleeve 201 and the second sleeve 202 to move upward, so that the piston disc 203 pushes the air in the first sleeve 201 and the second sleeve 202 upward and introduces the gas into the gas transmission tube. The air supply pipe 206 guides the gas into the interior of the gas supply semi-ring 207, and the gas inside the gas supply semi-ring 207 is ejected through the air blowing head 208. At this time, the air flow ejected from the air blowing head 208 is guided by the guide semi-ring 209 and blown to the soil surface at the soil sampling location, thereby blowing away the dead branches and fallen leaves on the soil surface and cleaning them to the other side. Then the sampling sleeve 103 carries the blade 104 and drills into the soil, allowing the soil to be sampled to enter the interior of the sampling sleeve 103.

[0046] While the piston disc 203 is moving upward, the lower half of the first sleeve 201 and the second sleeve 202 will be in a negative pressure state, and then the one-way sealing ring 211b will be opened under the action of the external atmospheric pressure, allowing the external air to enter the first sleeve 201 and the second sleeve 202 through the air intake groove 211a, thereby preventing the piston disc 203 from being unable to continue moving upward to exhaust due to the negative pressure.

[0047] During the up and down movement of the piston disc 203, the movement trajectory of the piston disc 203 can be limited by the sliding cooperation between the limiting groove 212b and the limiting rod 212a, thereby preventing the piston disc 203 from tipping over during the movement, resulting in reduced sealing of the piston disc 203 and air leakage.

[0048] After the soil to be sampled enters the sampling sleeve 103, the user activates the impact machine 101 to retract the movable rod 105, and then the movable rod 105 drives the sampling sleeve 103 and the blade 104 to move upward and retract. At this time, the transmission rope 205 stops transmitting the piston disc 203, and then the piston disc 203 is driven by the tension of the first tension spring 204 to move downward and reset, so that the piston disc 203 discharges the air inside the first sleeve 201 and the second sleeve 202 downward, and then the discharged air enters The piston rod 303 is pushed into the exhaust pipe 302, and driven by the airflow, the piston rod 303 moves inward, so that the piston rod 303 pushes the soil brushing half ring 301 to move inward and fit. At this time, during the upward movement of the sampling sleeve 103, the soil attached to the surface of the sampling sleeve 103 will be brushed off by the soil brushing half ring 301, thereby cleaning the soil attached to the surface of the sampling sleeve 103. If it rains, rainwater will drip into the water receiving tray 304a, and then the rainwater in the water receiving tray 304a will flow into the water receiving hose 304b. When the soil-brushing half ring 301 moves inward, the water receiving hose 304b is driven to move inward, so that the water receiving hose 304b is no longer in close contact with the sealing member 304d, and the rainwater in the water receiving hose 304b can continue to flow downward, thereby being guided to the inside of the soil-brushing half ring 301 and flowing to the surface of the sampling sleeve 103 through the seepage hole 304c, further softening the soil on the surface of the sampling sleeve 103, and cooperating with the soil-brushing half ring 301 to wash, thereby improving the cleaning effect, and when the rainwater flows in During the process of brushing the inside of the soil semi-ring 301, part of the rainwater will flow into the inner wall of the water receiving ring 304e-1 through the diversion pipe 304e-2, and flow out through the flushing groove 304e-3 opened on the water receiving ring 304e-1 and flow to the surface of the sampling sleeve 103, so that part of the uncleaned soil can be wetted and driven downward for cleaning during the flow of water. Then, the scraping ring 304e-4 can be used to scrape off the mud and water remaining on the surface of the sampling sleeve 103, further improving the cleaning effect of the surface of the sampling sleeve 103.

[0049] In the process of the piston disc 203 moving downward to discharge the gas, part of the gas will be driven to re-enter the interior of the gas pipe 206 through the exhaust support tube 210a and the exhaust hose 210b and be discharged through the gas supply half ring 207 and the blowing head 208 to blow off the relatively dry soil on the surface of the sampling sleeve 103, thereby assisting in cleaning.

[0050] As the cleaned sampling sleeve 103 continues to be driven by the impact machine 101 to move upward, the top and bottom of the plug block 402 are inclined, so that the plug block 402 will push the plug block 402 to move backward after contacting the rear side of the top of the sampling sleeve 103, and the second tension spring 404 will be pulled to further generate tension. When the plug block 402 corresponds to the slot 403 on the sampling sleeve 103, the plug block 402 will be inserted into the soil inside the sampling sleeve 103. At this time, the soil will be limited by the plug block 402 and cannot move upward. As the sampling sleeve 103 continues to move upward driven by the impact machine 101, the soil can gradually separate from the sampling sleeve 103 and fall out. At this time, the user can place the collection bag under the sampling sleeve 103 to collect the soil, thereby avoiding contamination of the removed soil.

[0051] During the drilling process, the surface cleaning mechanism 200 will be activated to blow away the dead branches and fallen leaves on the soil surface. During the resetting process of the sampling sleeve 103, the soil brushing cleaning mechanism 300 can be activated to wash the soil on the surface of the sampling sleeve 103. At the same time, the discharge mechanism 400 will be activated to take out the soil sample in the sampling sleeve 103.
