Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a soil sample efficient sampling mechanism. Background Art

[0002] Soil sampling refers to the method of collecting soil samples. Soil is composed of minerals formed by weathering of rocks, organic matter produced by the decomposition of animal and plant and microbial residues, soil organisms, as well as water, air, oxidized humus, etc. After soil sampling, the representative values ​​of factors affecting soil environmental quality can be measured to detect the fertility of the soil.

[0003] Existing soil sampling devices have certain shortcomings during use. For example, after the traditional sampling mechanism inserts the sampling tube into the ground for sampling, a push block is usually installed inside the sampling tube. The sample is pushed out by moving the push block and the sampling tube upward, or after the sampling tube is moved out of the ground, the sampling tube is vibrated by manual knocking to use vibration to move the sample out.

[0004] The above two methods both have major defects. For example, pushing the sample out with a push block can easily cause damage to the sample, and the manual knocking method is inefficient and therefore cannot meet the sampling requirements. In view of this, an efficient soil sample sampling mechanism is proposed to solve the above problems. Summary of the invention

[0022] Compared with the prior art, the present invention provides a soil sample efficient sampling mechanism, which has the following features:

[0023] Beneficial effects:

[0024] 1. The soil sample efficient sampling mechanism uses the push block in conjunction with the knocking method, and then cooperates with the spraying function, which can not only improve the sample feeding, but also flush the inner wall of the sampling tube, significantly improve the sampling efficiency, and reduce the sampling time and labor costs.

[0025] 2. When the efficient soil sample sampling mechanism is in use, the pressure applied to the spring changes by continuously squeezing the spring. At this time, the spring will vibrate due to the periodic change of pressure, so that when the knocking plate contacts the outer wall of the sampling tube, the vibration is transmitted through the transfer pad to achieve knocking on the sampling tube. The vibration helps to make the soil sample looser and more uniform in the sampling tube, thereby improving the accuracy and representativeness of the sampling. At the same time, the vibration energy can be used to knock on the sampling tube to make the soil particles remaining on the inner wall of the sampling tube fall off, thereby reducing the risk of soil residue and blockage.

[0026] 3. When the soil sample efficient sampling mechanism is in use, the use of a stationary push block can avoid wear and failure caused by telescopic movement, improve the durability and stability of the sampling tube, and install a spraying function on the push block, which can spray an appropriate amount of water or chemical solvent while pushing out the soil sample, which helps to loosen and discharge the soil particles. Combined with the use of the reciprocating vibration function, the sampling efficiency can be significantly improved, and the sampling time and labor costs can be reduced. This feeding method is suitable for different types of soils and sampling environments, and has strong adaptability and flexibility.

[0027] 4. When the soil sample efficient sampling mechanism is in use, by rotating the threaded sleeve and cooperating with the guide of the limiting structure, the through rod matched with its thread can be driven to move up and down, so that the push block can better match the length of the sampling tube, and it is also convenient for the subsequent disassembly and maintenance of the push block, further improving the adaptability and flexibility of the structure.

The walking trolley body 1, the electric lifting column 2 and the sampling tube 3 are all conventional equipment known to the public in the prior art, so their specific structural composition and working principle will not be described in detail in this article.

[0039] In this embodiment, a rotating mechanism for driving the sampling tube 3 is provided on the lower mounting platform 5, and the rotating mechanism includes a dual-axis motor 6 fixedly mounted on the lower mounting platform 5, a connecting shaft 7 rotatably mounted inside the lower mounting platform 5 and fixed to the upper surface of the sampling tube 3, a synchronous wheel 8 fixedly mounted on the top outer surface of the connecting shaft 7 and the output shaft of the dual-axis motor 6, and a synchronous belt 9 transmission-connected between the two synchronous wheels 8; the operating controller starts the electric lifting column 2 and the upper output shaft of the dual-axis motor 6, and utilizes the transmission cooperation of the synchronous wheel 8 and the synchronous belt 9 to lift and rotate the sampling tube 3, and at this time the sampling tube 3 is rotated into the ground for sampling.

[0040] In order to improve the material feeding efficiency, in this example, a vibration mechanism and a water delivery mechanism are arranged on the lower mounting platform 5. The vibration mechanism includes a knocking plate 11 arranged on one side of the outside of the sampling tube 3, a guide rod 12 and a spring 13 fixedly mounted on the knocking plate 11 close to the electric lifting column 2, and a mounting frame 10 is arranged on the side of the electric lifting column 2 close to the knocking plate 11, and a connecting frame 14 is welded between the mounting frame 10 and the lower mounting platform 5; the water delivery mechanism includes a water tank 15 and a pump body 16 fixedly mounted on the upper surface of the connecting frame 14, and a water tank 15 and a pump body 16 arranged inside the upper mounting platform 4 and the lower mounting platform 5. A through rod 17 extending into the interior of the sampling tube 3, a push block 18 detachably mounted on the bottom end of the through rod 17, a connecting pipe 20 connected to the top end of the through rod 17, a butt pipe 22 fixedly connected to the front and rear sides of the pump body 16, and a connecting pipe 21 fixedly connected between the connecting pipe 20 and one of the butt pipes 22, the other butt pipe 22 is fixedly connected to the water tank 15, a plurality of spray holes 26 are provided inside the through rod 17; a through hole 71 connected at the upper and lower ends is provided inside the connecting shaft 7, the through hole 71 is used to penetrate the connecting shaft 7 and extend to the interior of the sampling tube 3.

[0041] Specifically, the shape of the knocking plate 11 is adapted to the outer surface of the sampling tube 3, and a transfer pad 111 is fixedly installed on the side of the knocking plate 11 close to the sampling tube 3. The end of the spring 13 away from the electric lifting column 2 is fixed to the mounting frame 10, and the guide rod 12 runs through the inside of the mounting frame 10, and the spring 13 surrounds the outside of the guide rod 12. Through the installation of the guide rod 12, the knocking plate 11 can be limited and guided to make it reciprocate linearly, while increasing the squeezing of the spring 13 and improving the vibration effect.

[0042] There are two guide rods 12 and two springs 13, and the two guide rods 12 and the two springs 13 are symmetrically arranged, and the horizontal plate 2402 is located in the middle of the outer wall of the knocking plate 11. The bottom output shaft of the dual-axis motor 6 is rotatably connected to the connecting frame 14, and the connecting frame 14 can play a limiting role to ensure its stable output.

[0043] When in use, the knocking plate 11 reciprocates and abuts against the outer surface of the sampling tube 3. The knocking plate 11 will continue to squeeze the spring 13 when it reciprocates. At this time, the spring 13 will vibrate due to the periodic change of pressure, so that when the knocking plate 11 contacts the outer wall of the sampling tube 3, the vibration is transmitted through the transfer pad 111 to achieve knocking on the sampling tube 3. When the sampling tube 3 is raised or lowered, the push block 18 will push the soil sample and move it out of the sampling tube 3. The vibration helps to make the soil sample looser and more uniform in the sampling tube 3, thereby improving the accuracy and representativeness of the sampling.

[0044] In this example, the pump body 16 is composed of a pump housing 1601 and two rotors 1603. A pump cavity 1602 adapted to the two rotors 1603 is provided inside the pump housing 1601. The two rotors 1603 are rotatably mounted in the pump cavity 1602, and two meshing gears are mounted on the same side of the back of the two rotors 1603. The pump body 16 is a rotor pump, which realizes water delivery to the through rod 17, and the soil particles remaining on the inner wall of the sampling tube 3 fall off, thereby reducing the risk of soil residue and blockage.

[0045] It should be noted that the inner part of the through rod 17 is provided with a water delivery cavity connected with the spray hole 26, and the top of the through rod 17 is open, the connecting pipe 20 is rotatably connected with the top of the through rod 17, the connecting pipe 20 is a hard pipe, and the connecting pipe 21 is a hose. The inner part of the upper mounting platform 4 is rotatably installed with a threaded sleeve 19, the outer surface of the top of the through rod 17 is provided with a thread that matches the threaded sleeve 19, the thread of the through rod 17 passes through the inside of the threaded sleeve 19, and the outer surface of the threaded sleeve 19 is plugged with a lever.

[0046] Among them, a limiting structure 27 is installed on the outer surface of the top of the through rod 17, and the limiting structure 27 includes a connecting plate fixedly installed on the outer surface of the top of the through rod 17, and a limiting rod that penetrates the interior of the upper mounting platform 4 is fixedly installed on the upper surface of the connecting plate. By rotating the threaded sleeve 19 and cooperating with the guide of the limiting structure 27, the through rod 17 that is threadedly matched with it can be driven to move up and down, so that the push block 18 can better match the length of the sampling tube 3, and it is also convenient for the subsequent disassembly and maintenance of the push block 18, further improving the adaptability and flexibility of the structure. At the same time, other equipment such as a wrench can be used to rotate the threaded sleeve 19 to drive the through rod 17.

[0047] By coordinating the push block 18 with the water delivery mechanism, an appropriate amount of water or chemical solvent can be sprayed while pushing out the soil sample, which helps to loosen and discharge the soil particles. Combined with the use of the reciprocating vibration function, the sampling efficiency can be significantly improved, and the sampling time and labor costs can be reduced. This feeding method is suitable for different types of soils and sampling environments, and has strong adaptability and flexibility.

[0048] In order to improve the linkage effect between the structures, in this embodiment, the bottom output shaft of the dual-axis motor 6 is equipped with a first transmission structure 24 and a second transmission structure 25 used in linkage with the vibration mechanism and the water delivery mechanism. The first transmission structure 24 includes a turntable 2401 fixedly mounted on the bottom output shaft of the dual-axis motor 6, a horizontal plate 2402 fixedly mounted on the side of the knocking plate 11 away from the sampling tube 3, a crank 2403 mounted on the lower surface of the turntable 2401, a connecting rod 2404 rotatably mounted on the other side of the crank 2403, and a pulley 2403 rotatably mounted on the bottom end of the connecting rod 2404. 405, a slide groove 2406 adapted to the pulley 2405 is provided inside the horizontal plate 2402, and the pulley 2405 extends into the slide groove 2406 and slides with its inner wall; the second transmission structure 25 includes a transmission gear 2501, a driven gear 2502, and a transmission shaft 2503, the driven gear 2502 is fixedly mounted on one end of the transmission shaft 2503, and the driven gear 2502 is meshed with the transmission gear 2501, the transmission gear 2501 is fixedly mounted on the outer surface of the output shaft at the bottom of the dual-axis motor 6, and the other end of the transmission shaft 2503 is connected to the pump body 16. The crank 2403 is fixed to the turntable 2401, and when the turntable 2401 rotates, the crank 2403 is driven to rotate in a circle, at which time the connecting rod 2404 rotates and drives the pulley 2405 to slide in the slide groove 2406, thereby driving the knocking plate 11 to reciprocate.

[0049] In this embodiment, the transmission shaft 2503 is connected and fixed to one of the rotors 1603, the connecting frame 14 has a T-shaped appearance, and a limiting support seat for limiting the transmission shaft 2503 is fixedly installed on the outside of the connecting frame 14 to ensure stable rotation of the transmission shaft 2503 and improve the transmission effect.

[0050] The working principle of the above embodiment is:

[0051] When in use, the sampling tube 3 is moved to the specified position by the walking trolley 1, and then the controller is operated to start the electric lifting column 2 and the upper output shaft of the dual-axis motor 6, and the transmission cooperation of the synchronous wheel 8 and the synchronous belt 9 is used to make the sampling tube 3 rise and fall and rotate. At this time, the sampling tube 3 is screwed into the ground for sampling. After the sampling is completed, it is moved out by the electric lifting column 2, and the bottom output shaft of the dual-axis motor 6 is started. The first transmission structure 24 and the second production structure 25 are used to make the knocking plate 11 and the pump body 16 work. The knocking plate 11 reciprocates and abuts against the outer surface of the sampling tube 3. The knocking plate 11 will continue to squeeze the spring 13 when it reciprocates. At this time, the spring 13 will be pressed due to the pressure The periodic changes of the vibrations cause the knocking plate 11 to contact the outer wall of the sampling tube 3, and the vibration is transmitted through the transfer pad 111 to knock on the sampling tube 3. When the sampling tube 3 is raised or lowered, the push block 18 will push the soil sample and move it out of the sampling tube 3. The vibration helps to make the soil sample looser and more uniform in the sampling tube 3, thereby improving the accuracy and representativeness of the sampling. At the same time, the pump body 16 draws water or chemical solvents from the water tank 15, and transports them to the through rod 17 through the connecting pipe 21 and the connecting pipe 20, and finally sprays them out through the spray hole 26, so that the soil particles remaining on the inner wall of the sampling tube 3 fall off, thereby reducing the risk of soil residue and blockage.

In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
