Description

Technical Field

[0001] This application relates to the field of sampling device technology, specifically a shaped matrix sampling device. Background Technology

[0002] A shaping matrix is ​​a malleable material that can be molded into a specific shape under certain conditions and retain that shape. It can be used as a soil amendment in agriculture and horticulture, or as a basic material in industrial production and materials processing.

[0003] In this field, shaping substrates typically refer to cultivation substrates. They are primarily composed of organic and inorganic components. Organic components, such as peat, coconut coir, and compost, improve soil structure and provide nutrients needed for plant growth. Inorganic components, like perlite and vermiculite, mainly function to regulate the substrate's aeration and water retention.

[0004] For example, the patent with publication number CN218212056U discloses a soil sampling device, which includes a support mechanism, a sampling mechanism, a transmission component, a sampling component, and an opening and closing component. This allows the sampling component to start collecting soil when the borehole reaches the location where soil can be collected, under the action of the telescopic rod, effectively avoiding the situation where the required soil sample is mixed with other soil.

[0005] In the aforementioned patent, the cylinder provides initial power and positions the motor, which in turn drives the drill rod to rotate and enter the molding matrix. A fixed plate inside the drill rod supports the telescopic rod. During sampling, the telescopic rod extends, pushing the sampling slot downwards and extending it beyond the drill rod. The lower end of the sampling slot presses against the baffle, overcoming the spring force to open the opening and closing assembly, thus initiating sample collection. After sampling, the telescopic rod retracts, causing the sampling slot to move upwards back to its original position, at which point the spring force closes the baffle.

[0006] However, when the sampling trough is inserted into the shaped matrix for sampling, the matrix adheres to the surface of the trough. Although the trough retracts into the drilling rod as the telescopic rod moves it back, the two sets of baffles, due to their close fit, can scrape some areas of the trough during its upward movement to remove the matrix. However, some corners or edges of the trough may remain untouched by the baffles, leaving matrix residue. Consequently, as the sampling device moves after sampling, the matrix adhering to the trough falls onto the baffles and onto the spring. This matrix then enters the spring coils, interfering with the spring's normal extension and contraction. Therefore, a shaped matrix sampling device needs to be designed to solve this problem.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0008] Based on the aforementioned problems in the existing technology, the problem to be solved in this application is to provide a plastic matrix sampling device that addresses the issue in the aforementioned patent where, when the sampling groove is inserted into the plastic matrix for sampling, the plastic matrix adheres to the surface of the sampling groove. Although the sampling groove is retracted into the drilling rod by the telescopic rod, and although the two sets of baffles can scrape some parts of the sampling groove to remove the plastic matrix adhering to it during the upward movement of the sampling groove, there may be some corners or edges of the sampling groove that the baffles cannot fully reach, resulting in plastic matrix residue in these areas. Consequently, as the sampling is completed and the sampling device moves, the plastic matrix adhering to the sampling groove falls onto the baffles and onto the spring. The plastic matrix enters between the coils of the spring, interfering with the normal extension and contraction of the spring.

[0009] The technical solution adopted by this application to solve its technical problem is: a shaped matrix sampling device. The main components include: a base plate on which at least four sets of support rods are mounted, and a placement plate connecting the four sets of support rods; a sampling assembly mounted on the placement plate, the sampling assembly including a drilling rod for drilling holes in the shaped matrix, a motor for driving the drilling rod to rotate, and a cylinder for driving the drilling rod to move; an inner cavity is formed inside the drilling rod, a telescopic rod is mounted at the top of the inner arm of the inner cavity, and a sampling tube is mounted at the telescopic end of the telescopic rod; a mounting plate is mounted on the outer wall of the drilling rod, a fixing plate is mounted on the mounting plate, a bracket is mounted on the upper surface of the drilling rod, two sets of guide rods are connected between the bracket and the fixing plate, and sliders are slidably mounted on the guide rods; a lead screw is mounted on the bearing between the bracket and the fixing plate, and the slider is drivenly connected to the lead screw; a connecting rod is mounted on the side of the slider, a notch is formed on the drilling rod, and a cleaning scraper is mounted at one end of the connecting rod; and a cover is mounted on the inner wall of the drilling rod.

[0010] Furthermore, a push handle is connected between the support rods.

[0011] Furthermore, two sets of hinges are installed on the inner wall of one end of the drilling rod. The two sets of hinges are symmetrically arranged. A baffle is hinged to the hinge. A spring is provided between the baffle and the inner wall of the drilling rod.

[0012] Furthermore, a baffle is installed on the drill rod.

[0013] Furthermore, a rocker wheel is installed at one end of the lead screw.

[0014] Furthermore, the shield has a funnel structure.

[0015] The beneficial effects of this application are: the plastic matrix sampling device provided by this application, through the setting of baffle, mounting plate, fixing plate, bracket, guide rod, slider, lead screw, connecting rod, cleaning scraper ring and shield, can achieve comprehensive cleaning of the outer wall of the sampling tube, keep it in a relatively clean state, and prevent the plastic matrix from accumulating too much on the outer wall of the sampling tube and affecting the normal operation of the sampling tube.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figures 1-6 As shown, this application provides a shaped matrix sampling device, including a base plate 1, at least four sets of support rods 11 are fixedly installed on the base plate 1, a push handle is connected between two sets of support rods 11, the push handle is used to push the base plate 1 to move, and a universal wheel 13 is fixedly installed on the bottom surface of the base plate 1, the universal wheel 13 is used to move the base plate 1 to a designated position.

[0029] A placement plate 12 is connected between four sets of support rods 11. A sampling component 2 is installed on the placement plate 12. The sampling component 2 includes a cylinder 21 fixedly installed on the placement plate 12. The output end of the cylinder 21 passes through the placement plate 12. A motor 22 is fixedly installed at the output end of the cylinder 21. The motor 22 is suitable for moving up and down with the output end of the cylinder 21.

[0030] A drilling rod 23 is fixedly installed at the output end of the motor 22. A drill bit (not shown in the figure) is fixedly installed on the outer ring of the drilling rod 23. The drilling rod 23 is adapted to rotate with the output end of the motor 22 to drive the drill bit to rotate.

[0031] The cylinder 21 is used to start the machine to adjust the vertical height of the motor 22 and the drilling rod 23 so that the drill bit on the drilling rod 23 is aligned with the sampling position. Then, the motor 22 is started so that the drilling rod 23 and the drill bit begin to rotate. Then, by controlling the extension and retraction of the cylinder 21, the rotating drilling rod 23 and the drill bit gradually penetrate into the target object to start the drilling and sampling operation. During the drilling process, the depth of the drilling rod 23 can be controlled by adjusting the extension and retraction of the cylinder 21 according to the required sampling depth, so as to achieve the expected sampling depth.

[0032] The drilling rod 23 has an inner cavity 24. A telescopic rod 25 is fixedly installed at the top of the inner arm of the inner cavity 24. A sampling tube 26 is fixedly installed at the telescopic end of the telescopic rod 25. One end of the sampling tube 26 is open.

[0033] Normally, the telescopic rod 25 is in the retracted state, and the sampling tube 26 is retracted into the inner cavity 24 of the drilling rod 23 to protect the sampling tube 26 and avoid unnecessary damage during the drilling operation of the drilling rod 23. It also prevents the sampling tube 26 from coming into premature contact with debris and other impurities generated during the drilling process.

[0034] When the drilling rod 23 completes the drilling operation under the drive of the motor 22 and reaches the required sampling depth, the telescopic rod 25 begins to extend. The extension of the telescopic rod 25 will push the sampling tube 26 to extend downward along the inner cavity 24 towards the bottom of the drilling rod 23. As the sampling tube 26 extends, its open end will enter the bottom of the borehole or around the borehole wall and come into contact with the sample material to be collected. At this time, since the opening of the sampling tube 26 is open, the sample material will enter the interior of the sampling tube 26 to a certain extent.

[0035] Two sets of hinges 28 are fixedly installed on the inner wall of one end of the drill rod 23. The two sets of hinges 28 are symmetrically arranged. A baffle 29 is hinged to the hinge 28. A spring 210 is provided between the baffle 29 and the inner wall of the drill rod 23. One end of the spring 210 is rotatably connected to the inner wall of the drill rod 23, and the other end of the spring 210 is rotatably connected to the baffle 29.

[0036] Under normal circumstances, under the elastic force of the spring 210, the two sets of baffles 29 will be on the same horizontal line. Their positions are just enough to block one end opening of the sampling tube 26, preventing the material inside the sampling tube 26 from leaking out or the material outside from entering the sampling tube 26, thus playing a certain sealing and protection function.

[0037] In other words, the spring 210 applies a spring force to the baffle 29, so that the baffle 29 is in a stable position, thereby blocking the opening of the sampling tube 26. When an external force is applied to the baffle 29, the baffle 29 will overcome the spring force of the spring 210 and rotate around the hinge 28, thereby changing its position. When the external force disappears, under the restoring action of the spring force of the spring 210, the baffle 29 will return to its original position and block the opening of the sampling tube 26 again.

[0038] A cleaning assembly 3 is installed on the drilling rod 23. The cleaning assembly 3 includes a baffle 31 sleeved on the drilling rod 23. The baffle 31 is adapted to block the splashed plastic matrix during drilling when the cylinder 21 and the motor 22 start to drive the drill bit at one end of the drilling rod 23 to drill.

[0039] An mounting plate 32 is fixedly installed on the outer wall of the drilling rod 23, a fixing plate 33 is fixedly installed on the mounting plate 32, a bracket 34 is fixedly installed on the upper surface of the drilling rod 23, two sets of guide rods 35 are connected between the bracket 34 and the fixing plate 33, and a slider 36 is slidably installed on the guide rod 35. The slider 36 is suitable for moving along the straight direction of the guide rod 35.

[0040] A lead screw 37 is mounted on a bearing between the bracket 34 and the fixed plate 33. The slider 36 is connected to the lead screw 37 for transmission. When the lead screw 37 rotates, due to the helical structure of the lead screw 37, the rotational motion is converted into the linear motion of the slider 36, so that the slider 36 moves along the linear direction of the guide rod 35.

[0041] A rocker wheel (not shown in the figure) is fixedly installed at one end of the lead screw 37. The operator drives the lead screw 37 to rotate by turning the rocker wheel. Depending on the rotation direction of the lead screw 37 (clockwise or counterclockwise), the slider 36 will move in different directions along the guide rod 35 accordingly.

[0042] A connecting rod 38 is fixedly installed on the side of the slider 36. A notch 27 adapted to the diameter of the connecting rod 38 is opened on the drilling rod 23. A cleaning scraper ring 39 is fixedly installed at one end of the connecting rod 38. The cleaning scraper ring 39 is movably sleeved on the outer wall of the sampling tube 26. The notch 27 provides space for the movement of the connecting rod 38, enabling it to drive the cleaning scraper ring 39 without interfering with other internal components of the drilling rod 23. The cleaning scraper ring 39 is movably sleeved on the outer wall of the sampling tube 26, fitting tightly against the sampling tube 26, and can directly contact the outer wall of the sampling tube 26.

[0043] When the lead screw 37 rotates via the rocker wheel, the slider 36 moves linearly along the guide rod 35. Since the connecting rod 38 is fixedly connected to the slider 36, the connecting rod 38 moves along with the slider 36. The movement of the connecting rod 38 drives the cleaning scraper ring 39 to move axially linearly along the outer wall of the sampling tube 26. During this process, the cleaning scraper ring 39 scrapes off the plastic matrix attached to the outer wall of the sampling tube 26.

[0044] The reciprocating linear motion of the cleaning scraper ring 39 ensures thorough cleaning of the outer wall of the sampling tube 26. Furthermore, when removing the sampled plastic matrix, it simultaneously pushes out the plastic matrix accumulated on the baffle 29, keeping the surface of the sampling tube 26 relatively clean. This prevents excessive accumulation of plastic matrix on the outer wall of the sampling tube 26, which could affect its normal operation, such as its extension and retraction, or prevent impurities from falling into the sampling tube 26 and contaminating the collected samples. This ensures the accuracy of the sampling work and the reliability of the sampling device, extends the service life of the sampling tube 26, and improves the overall efficiency of the sampling system.

[0045] A shield 310 is fixedly installed on the inner wall of the drilling rod 23. The shield 310 has a funnel structure and is movably sleeved on the sampling tube 26 to shield the spring 210, preventing these substances from contacting and accumulating on the spring 210. If too many impurities adhere to the surface of the spring 210, it may affect its elasticity, causing the baffle 29 to fail to open and close properly.

[0046] When the sampling tube 26 collects a sample and retracts, some sample may remain outside the sampling tube 26. The shield 310 can guide these samples to flow along its funnel-shaped inner wall, keeping them away from the active areas of the spring 210 and the baffle 29. This prevents the sample from contaminating the spring 210 and the baffle 29, ensures that the baffle 29 can close properly, prevents sample leakage, and also reduces the possibility of sample remaining in other locations inside the drill rod 23, affecting its use.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
