The bottom of the sampling shell is formed with a conical surface, and the diameter of the conical surface gradually decreases in the vertical downward direction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The sampling cavity is sealed by several sealing triangles to ensure the integrity of the sampled soil and avoid the fragmentation or partial falling of the soil during the sampling process, thereby ensuring the accuracy and representativeness of the sampling. The guarantee of sampling integrity enables the soil at different heights to be tested during the test, thereby obtaining more accurate test results and improving the accuracy of the test.

[0017] 2. The soil in the sampling cavity is held in a tight state by a plurality of tightly compressed blocks, thereby reducing the gaps between the soils. By holding in place to reduce the gaps between the soils, the position of the soil in the sampling cavity can be prevented from changing during the movement of the sampling shell, thereby ensuring that the position of the soil remains stable after the sampling is completed, thereby reducing the possibility of interference with the test results and improving the reliability and accuracy of the test results.

[0018] 3. By setting a limit baffle to prevent soil from entering the sealing expansion slot, the smooth movement of the sealing triangle block is maintained to avoid affecting the smoothness of the equipment use. After the sampling is completed, during the movement of the sealing triangle block, the sealing slope is fitted with the downward slope, and the limit baffle can remove the soil attached to the sealing slope to prevent the soil from entering the sealing expansion slot, thereby preventing soil residue from affecting the next sampling. After the sealing triangle block enters the sealing expansion slot, the sampling cavity can be reopened to facilitate the removal of the sampled soil.

[0019] 4. The soil can be taken out of the sampling cavity by pressing the pushing handle. The initial movement of the pushing-out holding block and the pushing-out extension rod compresses the gas in the buffer cavity. The gas in the buffer cavity can enter the annular expansion airbag through the air vent, causing the annular expansion airbag to expand, thereby improving the fit between the annular expansion airbag and the side wall of the sampling cavity. Further movement of the pushing-out holding block can push the soil in the sampling cavity through the holding slider and the annular expansion airbag, thereby completing the removal of the soil. Since the annular expansion airbag fits more closely with the side wall of the sampling cavity, the friction between the annular expansion airbag and the side wall of the sampling cavity is greater, and the soil attached to the side wall of the sampling cavity can be better pushed out, thereby avoiding the soil adhering to the side wall of the sampling cavity and affecting the next sampling and detection results.

[0042] Two fixing handles 13 are fixedly mounted on the top of the sampling housing 1, and the two fixing handles 13 are symmetrically arranged. A conical surface 14 is formed on the bottom of the sampling housing 1, and the diameter of the conical surface 14 gradually decreases in the vertical downward direction.

[0043] In one embodiment, when the operator needs to perform an ecological environment test on the soil, the operator needs to sample the soil in the environment, and then analyze and test the sampled soil through an external testing device, mainly testing the organic matter, nutrients (such as nitrogen, phosphorus, potassium), pH value, and the number and diversity of microorganisms in the soil. The sampling shell 1 is a cylinder. In the process of sampling the soil, if it is on soft soil, the operator can directly hold the two fixed handles 13 with both hands to drive the sampling shell 1 into the soil. The bottom of the sampling shell 1 is provided with a conical surface 14, and the conical surface 14 can make the sampling shell 1 more easily inserted into the soil. If it is on harder soil, the operator can use external equipment to press down the two fixed handles 13 to drive the sampling shell 1 into the soil. The sampling shell 1 is inserted into the soil. When the sampling shell 1 is inserted into the soil, the soil can enter the sampling cavity 3 in the sampling shell 1. Then the operator can rotate the two rotating blocks 313 counterclockwise with the push-out extension rod 41 as the central axis. The two rotating blocks 313 can drive the rotating ring block 311 to rotate. The rotating ring block 311 can drive a plurality of wedge-shaped connecting arc rods 32 to rotate around the central axis of the sampling shell 1.

When the guide disk 33 rotates, it can drive the blocking guide rod 23 to move in the direction of the sampling cavity 3 through the guide arc groove 331. The blocking guide rod 23 can drive the blocking slide plate 21 in the blocking telescopic groove 4 to the direction of the sampling cavity 3. When the locking cam 313 is in the closed position, the locking cam 313 is in the closed position, and the locking cam 313 is in the closed position, so that the locking cam 313 is in the closed position. The soil above the several blocking triangular blocks 22 cannot be separated from the bottom of the sampling cavity 3 due to being blocked, thereby completing the soil sampling, and being able to completely take out a whole section of soil, ensuring the integrity of the sampled soil. During the detection, it is necessary to detect soils at different heights, and when the integrity of the sampled soil is guaranteed, more accurate detection results can be obtained, thereby improving the accuracy of the detection. The sampling cavity 3 is blocked by several blocking triangular blocks 22, and the integrity of the sampled soil is ensured, avoiding the fragmentation or partial falling of the soil during the sampling process, thereby ensuring the accuracy and representativeness of the sampling. The guarantee of sampling integrity enables the soils at different heights to be detected during the detection, thereby obtaining more accurate detection results.Improves the accuracy of detection.

[0044] In one embodiment, the distance between the compression inclined surface 541 and the anti-slip block 51 gradually increases in the counterclockwise direction. When the wedge-shaped connecting arc rod 32 rotates, it can abut against the compression inclined surface 541 of the wedge-shaped magnetic suction slider 54 through the trigger inclined surface 321, so that the wedge-shaped magnetic suction slider 54 moves into the tight receiving groove 12. When the wedge-shaped magnetic suction slider 54 moves, it can compress the tight spring 53. Under normal circumstances, the tight spring 53 is in a natural state, and neither elastic force nor tension is generated. When the tight spring 53 is compressed, it can generate elastic force, and the elastic force can make the anti-slip block 51 move toward the sampling cavity 3. The anti-slip block 51 can drive the tight compression block 52 to move into the sampling cavity 3. During the movement of the tight compression block 52, the soil in the sampling cavity 3 will be compressed, so that the soil in the sampling cavity 3 is in a tight state, reducing the gaps between the soils, and avoiding the presence of large gaps in the soil in the sampling cavity 3 after the sampling is completed. When the sampling shell 1 is moved before the detection, shaking and the like occur, causing the position in the soil to change. The invention relates to a method for making an injection molded product of the present invention to a method for injecting ink into the injection molded product 10 so that it can be easily deformed into and then moved back to the injection molded product 10 by the injection molding machine. The method further relates to a method for injecting ink into the injection molded product 10 so that it can be easily deformed into and then moved back to the injection molded product 10 by the injection molding machine.

[0045] When the sampling shell 1 is inserted into the soil, the soil can enter the sampling cavity 3. A limit baffle 10 is provided at one end of the sealing expansion slot 4 close to the sampling cavity 3. The limit baffle 10 can prevent the soil in the sampling cavity 3 from entering the sealing expansion slot 4 and affecting the movement of the sealing triangle block 22. When the sealing triangle block 22 moves toward the sampling cavity 3, the sealing triangle block 22 can resist the downward inclined surface 101 of the limit baffle 10 through the sealing inclined surface 221, so that the downward inclined surface 101 moves downward to compress the baffle return spring 9, and the downward inclined surface 101 can completely enter the baffle expansion slot 8. When the sampling is completed and the sampled soil needs to be taken out, the sealing triangle block 22 moves in the direction away from the sampling cavity 3, and the limit baffle 10 can move upward by the elastic force of the baffle return spring 9, so that the downward inclined surface 101 is in contact with the sealing inclined surface 221 of the sealing triangle block 22. The soil attached to the blocking slope 221 is scraped off, thereby achieving a cleaning effect on the blocking slope 221, and preventing the blocking triangle block 22 from bringing the soil into the blocking expansion slot 4 when moving. After the blocking triangle block 22 enters the blocking expansion slot 4, the sampling cavity 3 can be reopened to facilitate the removal of the soil in the cavity sampling cavity 3. The soil is prevented from entering the blocking expansion slot 4 by setting a limit baffle 10, thereby maintaining the smoothness of the movement of the blocking triangle block 22 to avoid affecting the smoothness of the equipment use. After the sampling is completed, during the movement of the blocking triangle block 22, the blocking slope 221 is fitted with the downward moving slope 101, and the limit baffle 10 can clear the soil attached to the blocking slope 221 to prevent the soil from entering the blocking expansion slot 4 to avoid the soil residue affecting the next sampling. After the blocking triangle block 22 enters the blocking expansion slot 4, the sampling cavity 3 can be reopened to facilitate the removal of the sampled soil.

[0046] It is worth noting that the distance between the guide arc groove 331 and the sampling cavity 3 gradually decreases in the counterclockwise direction, and the middle part of the guide arc groove 331 arches in the clockwise direction. When the rotating ring block 311 rotates through the guide arc groove 331 to move the blocking triangle block 22, the movement speed of the blocking triangle block 22 is from slow to fast while the rotation speed of the rotating ring block 311 remains unchanged. When the blocking triangle block 22 is first inserted into the soil in the sampling cavity 3, the resistance is large. Inserting it into the soil at a slower speed can improve the stability of its movement. When the blocking triangle block 22 is inserted into the soil with a certain initial velocity, the movement speed of the blocking triangle block 22 can be increased, so that several blocking triangle blocks 22 can resist each other faster to block the sampling cavity 3 and improve work efficiency.

[0047] In one embodiment, when the blocked sampling cavity 3 is opened and the soil in the sampling cavity 3 needs to be taken out for testing, the operator can press the push-out handle 43 in the direction of the sampling shell 1, and the push-out handle 43 can drive the push-out extension rod 41 to move synchronously, and the push-out extension rod 41 can drive the push-out abutment block 42 to move in the direction of the buffer cavity 621, and the friction between the push-out extension rod 41 and the buffer ring block 61 is less than the friction between the abutment slider 63 and the side wall of the sampling cavity 3. When the push-out extension rod 41 moves, it can slide on the inner side wall of the buffer ring block 61, and when the push-out abutment block 42 moves downward and abuts against the top of the abutment slider 63, the push-out abutment block 42 and the push-out extension rod 41 are in contact with each other. The rod 41 can compress the gas in the buffer cavity 621, and the gas in the buffer cavity 621 can enter the annular expansion airbag 64 through the vent hole 631. The gas entering the annular expansion airbag 64 will expand outward or downward, so that the annular expansion airbag 64 can fit the side wall of the sampling cavity 3 more closely. When the pushing-out abutting block 42 abuts against the top of the abutting slider 63 and moves further downward, the abutting slider 63 can drive the annular expansion airbag 64 to move downward. The abutting slider 63 and the annular expansion airbag 64 can push the soil in the sampling cavity 3 together, thereby completing the removal of the sampled soil, and then testing the soil. Then the operator can pull the pushing-out handle 43 to move upward. The push handle 43 can drive the push extension rod 41 to move upward, and the push extension rod 41 can drive the push abutment block 42 to move upward. When the push abutment block 42 moves to abut against the connected annular cover 62, the gas in the annular expansion airbag 64 can enter the buffer cavity 621 through the vent hole 631, so that the expanded annular expansion airbag 64 shrinks, reducing the friction between the annular expansion airbag 64 and the sampling cavity 3, so that the push abutment block 42 can be pushed against the connected annular cover 62 and move further upward more smoothly. By pressing the push handle 43, the soil can be taken out of the sampling cavity 3. The initial movement of the push abutment block 42 and the push extension rod 41 compresses the buffer cavity 621. The gas in the buffer cavity 621 can enter the annular expansion airbag 64 through the vent hole 631, causing the annular expansion airbag 64 to expand, thereby improving the fit between the annular expansion airbag 64 and the side wall of the sampling cavity 3. The further movement of the pushing-out abutment block 42 can push out the soil in the sampling cavity 3 through the abutment slider 63 and the annular expansion airbag 64, thereby completing the removal of the soil. Since the annular expansion airbag 64 and the side wall of the sampling cavity 3 fit more closely, the friction between the annular expansion airbag 64 and the side wall of the sampling cavity 3 is greater, and the soil attached to the side wall of the sampling cavity 3 can be better pushed out, thereby avoiding the soil adhering to the side wall of the sampling cavity 3 and affecting the next sampling detection result.

[0048] During installation, several wedge-shaped connecting arc rods 32 are fixedly installed on the bottom of the rotating ring block 311, the guide disc 33 is fixedly installed on the bottom of several wedge-shaped connecting arc rods 32, the blocking slide plate 21 is slidably installed on the end of the blocking telescopic groove 4 away from the sampling chamber 3, the blocking triangle block 22 is fixedly installed on the side wall of the blocking slide plate 21 close to the sampling chamber 3, the blocking guide rod 23 is fixedly installed on the top of the blocking slide plate 21, the rotating ring block 311 is rotatably installed on the side wall of the rotating ring groove 5, the two shift block shafts 312 are respectively rotatably installed in the two shift block receiving grooves 314 through torsion springs, the two rotating shift blocks 313 are respectively fixedly installed on the side walls of the two shift block shafts 312, and the anti-slip block 51 is slidably installed on the side wall of the square anti-slip groove 121, tightly pressing The shrinking block 52 is fixedly mounted on the side wall of the anti-slip block 51 close to the sampling chamber 3, the tightening spring 53 is fixedly mounted on the side wall of the anti-slip block 51 away from the sampling chamber 3, the wedge-shaped magnetic slider 54 is fixedly mounted on the end of the tightening spring 53 away from the anti-slip block 51, the push-out extension rod 41 is slidably mounted on the side wall of the push-out through groove 2, the push-out holding block 42 is fixedly mounted on the bottom of the push-out extension rod 41, the push-out handle 43 is fixedly mounted on the top of the push-out extension rod 41, the buffer ring block 61 is slidably mounted on the bottom side wall of the push-out extension rod 41, the connecting annular cover 62 is fixedly mounted on the outer side wall of the buffer ring block 61, the holding slider 63 is fixedly mounted on the bottom of the connecting annular cover 62, and the annular expansion airbag 64 is fixedly mounted on the bottom of the holding slider 63.

[0049] The present case can achieve the following: 1. By sealing the sampling cavity 3 with a plurality of sealing triangles 22, the integrity of the sampled soil is ensured, and the soil is prevented from being broken or partially detached during the sampling process, thereby ensuring the accuracy and representativeness of the sampling. The guarantee of sampling integrity enables the soil at different heights to be tested during the test, thereby obtaining more accurate test results and improving the accuracy of the test.

[0050] 2. The soil in the sampling cavity 3 is pressed against by a plurality of tight compression blocks 52, so that the soil in the sampling cavity 3 is in a tight state, and the gaps between the soil are reduced. By pressing against and reducing the gaps between the soil, the position of the soil in the sampling cavity 3 can be prevented from changing during the movement of the sampling shell 1, ensuring that the position of the soil remains stable after the sampling is completed, thereby reducing the possibility of interference with the test results and improving the reliability and accuracy of the test results.

[0051] 3. By setting a limit baffle 10, soil is prevented from entering the blocked telescopic groove 4, thereby maintaining the smooth movement of the blocking triangle block 22 to avoid affecting the smoothness of the equipment use. After the sampling is completed, during the movement of the blocking triangle block 22, the blocking slope 221 is fitted with the downward slope 101, and the limit baffle 10 can remove the soil attached to the blocking slope 221 to prevent the soil from entering the blocked telescopic groove 4, thereby avoiding soil residue affecting the next sampling. After the blocking triangle block 22 enters the blocked telescopic groove 4, the sampling cavity 3 can be reopened to facilitate the removal of the sampled soil.

[0052] 4. By pressing the push-out handle 43, the soil can be taken out from the sampling cavity 3. The initial movement of the push-out abutment block 42 and the push-out extension rod 41 compresses the gas in the buffer cavity 621. The gas in the buffer cavity 621 can enter the annular expansion airbag 64 through the vent hole 631, causing the annular expansion airbag 64 to expand, thereby improving the fit between the annular expansion airbag 64 and the side wall of the sampling cavity 3. The further movement of the push-out abutment block 42 can push out the soil in the sampling cavity 3 through the abutment slider 63 and the annular expansion airbag 64, thereby completing the removal of the soil. Since the annular expansion airbag 64 fits more closely with the side wall of the sampling cavity 3, the friction between the annular expansion airbag 64 and the side wall of the sampling cavity 3 is greater, and the soil attached to the side wall of the sampling cavity 3 can be better pushed out, thereby avoiding the soil adhering to the side wall of the sampling cavity 3 and affecting the next sampling and detection results.
