Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, specifically a sampling device for forestry ecological protection. Background Art

[0002] Sampling in forestry ecological protection is a key technical support for protecting biodiversity. It is a technical means to collect various samples from forest ecosystems through scientific methods for monitoring and evaluating the ecological environment status, biodiversity, forest health, and interference factors such as pollution, pests and diseases, and climate change. As the most active organ for the interaction between trees and the external environment, the cell sap of leaves, that is, the extract after the leaves are crushed, contains rich physiological metabolites and environmental response signals. Specifically, through the analysis of leaf sap, precise detection of pollutants such as heavy metals, organic pollutants, and pathogenic microorganisms can be achieved, thereby providing a key basis for the dynamic monitoring and comprehensive evaluation of the forestry ecological environment.

[0003] A Chinese patent with the authorization announcement number CN114720178B discloses a sampling device for large forest trees, including a movable bottom plate. A lifter and a control board are provided on the top of the bottom plate. It also includes an installation box, a sampling component for collecting leaves, an adjustment component for adjusting the sampling component, a feeding hopper, a conveying pipe, an anti-blocking component for preventing the conveying pipe from being blocked, and a collecting component for collecting leaves. Through the cooperation between the telescopic rod, spring, cam, and buffer plate in the anti-blocking component, the conveying pipe can be reciprocally shaken, thereby avoiding the phenomenon of blockage during the transportation of samples. In addition, through buffering, the conveying pipe can be well protected, thus preventing the phenomenon of confusion of multiple groups of samples, effectively improving the sampling efficiency, and ensuring accurate sampling of samples. However, after the leaves are picked, the above-mentioned device needs to complete the collection of leaves through tools such as tweezers and sampling bags, and then manually transfer them to a crushing or storage container. During this process, the complex terrain in the wild is extremely likely to cause the leaves to spill from the tools or containers, contaminating the exposed leaf samples. This non-standard transfer process will further magnify the error in large-scale ecological surveys, resulting in a decrease in the comparability of data at different sampling points, seriously affecting the scientific nature of forestry ecological assessment. Summary of the Invention

A lifting member is slidably connected to the outside of the containing container. When the lifting member moves upward, it is inserted between the push plate and the inner side of the mounting frame and abuts against the push plate to move the push plate; Wherein, when the activating member pushes the lifting member to move along the axis of the containing container towards the container mouth, the push plate is pushed to move towards the inside of the containing container. During the movement, the pressing plate on the inner side of the push plate is inserted into the containing container through the slot until the pressing plate abuts against the branch inserted into the containing container. At this time, the containing container is driven to move by the activating member. During the movement, the pressing plate scrapes the leaves off the branch.

[0006] Further: The containing container includes a leaf picking cylinder, a juice extracting cylinder and a liquid containing cylinder, which are distributed from top to bottom and are threadedly connected. The guiding groove and the slot are both provided on the leaf picking cylinder.

[0007] Further: The lifting member includes a top ring slidably inserted into the guiding groove, and the top ring is sleeved on the outside of the leaf picking cylinder. A push block is fixedly connected to the side end of the top ring. The push block is arranged between the push plate and the inner side of the mounting frame, and the inclined surface of the push plate abuts against the bottom end of the push plate. A second spring is fixedly connected to the bottom end of the top ring, and one end of the second spring is fixedly connected to a linkage ring, and the linkage ring is sleeved on the outside of the leaf picking cylinder.

[0008] Further: A relief groove is formed in the side end of the pressing plate, and a guiding block is fixedly connected to the inside of the relief groove.

A telescopic rod is fixedly connected to the bottom end of the connecting frame.

[0010] Further: the push ring is also provided with a mounting block, bolts, a connecting frame, a nut and a telescopic rod.

[0011] Further: the juice extraction component includes a filter plate fixedly arranged at the bottom end of the juice extraction barrel, the bottom end of the filter plate is rotatably connected to a linkage block, the top of the linkage block passes through the filter plate and is fixedly connected to a spiral rod with a spiral groove on the outer circular surface, the bottom end of the spiral rod is provided with a lifting groove, the outer side of the spiral rod is sleeved with a sleeve, and the sleeve is slidably plugged into the lifting groove, and the outer side of the sleeve is fixedly connected to a crushing blade.

[0012] Further: a receiving groove is provided at the bottom end of the sleeve, a spring three is fixedly connected to the top end of the receiving groove, and one end of the spring three is fixedly connected to the top end of the linkage block.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes precise adjustment of sampling angle and height through the activation member. Its articulated connection frame cooperates with the nut to adjust the angle of the container to adapt to branches in different orientations such as tilted and vertical. The telescopic rod supports height adjustment to ensure that the branches are accurately inserted from the container mouth. After separating the telescopic rod, the push ring moves up along the guide column to trigger the leaf picking action. The manual operation force is amplified by the inclined transmission of the spring 2 and the push block, reducing the labor intensity of the sampler climbing or raising the arm. The T-shaped guide column can also prevent the push ring from falling off the track. 2. The present invention realizes automatic leaf picking and precise positioning through the leaf picking member. Two sets of symmetrical pressing plates are linked with the push plate through the magnetic block. When the push block moves up, the pressing plate slides into the leaf picking cylinder from the slot. The semicircular straight surface can fit the branches, so that the success rate of leaf scraping is improved. The pre-docking design of the guide block and the spiral rod enables the pressing plate to automatically move to the juice collection area after leaf picking. The transfer of leaves from the leaf picking cylinder to the filter plate can be completed without additional operation, reducing the sample spillage caused by manual intervention; 3. The present invention realizes the automation of the whole process of blade crushing and juice squeezing through the juice extracting part. The motor drives the crushing blade to rotate and crush the blade. The filter plate initially filters the juice. Then the pressing plate moves down along the spiral groove to squeeze the broken leaves. The secondary juice extraction improves the total juice extraction rate. The sliding connection between the lifting groove and the cross-shaped plug block allows the sleeve to move axially during the rotation crushing. During maintenance, it only needs to unscrew the liquid holding cylinder and the juice extracting cylinder to clean the filter plate residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] 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.

[0018] Reference Figures 1 to 15 In an embodiment of the present invention, a sampling device for forestry ecological protection includes: a container 1, a leaf-picking member 3 for picking leaves from branches inserted into the container 1 is provided on the container 1, a juice-collecting member 4 for obtaining juice from the removed leaves is provided on the container 1, and an activating member 2 for activating the leaf-picking member 3 is provided on the container 1; The containing container 1 comprises a leaf picking cylinder 11, a juice collecting cylinder 12 and a liquid storing cylinder 13, which are arranged from top to bottom and are threadedly connected. A guide groove 15 is provided at the side end of the leaf picking cylinder 11, and a slot 14 is provided through the side end of the leaf picking cylinder 11, and the slot 14 is located above the guide groove 15. Two groups of the slot 14 and the guide groove 15 are provided, which are symmetrically distributed on both sides of the leaf picking cylinder 11.

[0019] The activating member 2 includes a mounting ring 21 fixedly connected to the outside of the leaf-picking cylinder 11, and a guide column 22 is inserted through one end of the mounting ring 21, and the guide column 22 is T-shaped, and five groups of guide columns 22 are arranged, which are evenly distributed at one end of the mounting ring 21, and a push ring 23 is fixedly connected to the end face of the guide column 22, and the push ring 23 is sleeved on the outside of the leaf-picking cylinder 11 and is located below the linkage ring 37, and a mounting block 24 is fixedly connected to the side end of the mounting ring 21, and a connecting frame 26 is arranged at the side end of the mounting block 24, and the connecting frame 26 is U-shaped, and bolts 25 are inserted through the side ends of the mounting block 24 and the connecting frame 26, and nuts 27 are threadedly connected to the outer side of the bolt 25, and the nuts 27 are arranged at the connecting frame 26, the mounting block 24 is hinged to the connecting frame 26 by bolts 25, and the bottom end of the connecting frame 26 is fixedly connected with a telescopic rod 28. The push ring 23 is also provided with a mounting block 24, bolts 25, a connecting frame 26, nuts 27 and a telescopic rod 28. When the connecting frame 26 is rotated and the nut 27 is tightened, the container 1 and the telescopic rod 28 are adjusted to an angle at which branches can be inserted, thereby realizing flexible spatial positioning. The telescopic rod 28 is used to adjust the height of the device so that the branches are inserted from the container opening at the top of the leaf picking tube 11, and then the mounting ring 21 and the telescopic rod 28 on the linkage ring 37 are separated, and the push ring 23 slides upward along the guide column 22 to activate the leaf picking member 3 to perform the leaf picking operation.

[0020] Adopting the above solution: Through the locking of the articulated connecting frame 26 and the nut 27, the device can flexibly adjust the angle to adapt to branches with different growth directions, improving the sampling efficiency. The separation action of the telescopic rod 28 is converted into the linear motion of the push ring 23. By using the combination of the inclined plane and the spring, the smaller operating force is amplified into the clamping force of the pressing plate 34, reducing the manual operation intensity. The combined structure of the mounting ring 21, the guide post 22 and the push ring 23 enables the activation part 2 to be quickly assembled outside the container 1, facilitating equipment maintenance and component replacement. The T-shaped guide post 22 restricts the movement trajectory of the push ring 23 to prevent it from detaching from the device. The separation action of the telescopic rod 28 requires active operation, reducing the risk of false triggering and ensuring the use safety.

[0021] The leaf picking member 3 includes a mounting frame 31 fixedly connected to the outer side of the leaf picking cylinder 11. The mounting frame 31 is U-shaped, and there are two sets of mounting frames 31, symmetrically distributed on the outer side of the leaf picking cylinder 11. A set of push plates 33 are slidably inserted into each set of mounting frames 31. Sliders are fixedly connected to both sides of the push plate 33, which are adapted to the chutes on both inner sides of the mounting frame 31. The push plate 33 is concave-shaped, and the groove of the push plate 33 is semi-circular. Magnets are embedded on the inner side of the concave-shaped groove of the push plate 33. A set of pressing plates 34 are slidably inserted into each set of slots 14. The pressing plate 34 is semi-circular, and the outer diameter of the pressing plate 34 is the same as the inner diameter of the leaf picking cylinder 11. When the two pressing plates 34 completely enter the leaf picking cylinder 11, there is friction between the outer side of the pressing plate 34 and the inner wall of the leaf picking cylinder 11. Magnets are also embedded on the arc surface of the semi-circular pressing plate 34, and the corresponding surfaces of the magnets on the pressing plate 34 and the magnets on the push plate 33 are of opposite poles. Avoidance grooves 35 are formed on the straight surfaces of the sides of each semi-circular pressing plate 34, and guiding blocks 36 are fixedly connected to the inner sides of the avoidance grooves 35. The guiding blocks 36 are spiral-shaped. A first spring 32 is fixedly connected to the inner side of the mounting frame 31. One end of the first spring 32 is fixedly connected to the push plate 33. There are four sets of the first springs 32, symmetrically distributed on the inner sides of the two mounting frames 31. A jacking member 311 is slidably connected to the outer side of the containing container 1. When the jacking member 311 moves upward, it is inserted between the push plate 33 and the inner side of the mounting frame 31 and abuts against the push plate 33 to move the push plate 33. The jacking member 311 includes a top ring 39 slidably inserted into the guiding groove 15. The top ring 39 is composed of a ring and two inserting blocks symmetrically distributed inside the ring. The inserting blocks are slidably inserted into the guiding groove 15, and the ring is sleeved on the outer side of the leaf picking cylinder 11. A pushing block 310 is fixedly connected to the side end of the top ring 39. The cross section of the pushing block 310 is a right trapezoid with the inclined surface facing upward. There are two sets of the pushing blocks 310, symmetrically distributed on both sides of the ring in the top ring 39. The pushing blocks 310 are arranged between the push plate 33 and the inner side of the mounting frame 31, and the inclined surface of the pushing block 310 abuts against the bottom end of the push plate 33. A second spring 38 is fixedly connected to the bottom end of the top ring 39. One end of the second spring 38 is fixedly connected to a linkage ring 37. The linkage ring 37 is sleeved on the outer side of the leaf picking cylinder 11. There are four sets of the second springs 38, symmetrically distributed at the bottom end of the top ring 39. The elastic force of the second spring 38 is greater than the elastic force of the first spring 32, and the elastic force of the second spring 38 is less than the insertion friction force between the guide post 22 and the mounting ring 21. When the push ring 23 of the activating member 2 moves upward, it drives the linkage ring 37 to drive the second spring 38, the top ring 39 and the pushing block 310 to move upward synchronously. The inclined surface of the pushing block 310 squeezes the push plate 33 to slide along the chute of the mounting frame 31 towards the inner side of the leaf picking cylinder 11, causing the first spring 32 to be stretched. The magnets in the groove of the push plate 33 attract each other due to opposite poles, driving the pressing plate 34 to slide from the slot 14 into the leaf picking cylinder 11. The straight surfaces of the two semi-circular pressing plates 34 abut against the branches. At this time, the linkage ring 37 continues to move upward to compress the second spring 38. When the device pulls out the branches outward, the pressing plate 34 abuts against the surface of the branches, scraping the leaves into the juice extraction cylinder 12. Subsequently, the second spring 38 stretches to push the top ring 39 upward, and the pushing block 310 drives the pressing plate 34 to move towards the screw rod 43.Until the guide block 36 is embedded in the helical groove of the screw rod 43. After the guide block 36 is embedded in the helical groove of the screw rod 43, due to the magnetic adsorption between the push plate 33 and the pressing plate 34, the pressing plate 34 will not rotate with the screw rod 43. Instead, under the guidance of the helical groove of the screw rod 43 and the guide block 36, it overcomes the magnetic adsorption and moves downward. When the pressing plate 34 is in contact with the inner wall of the leaf picking cylinder 11, the frictional force between them will not cause the pressing plate 34 to rotate with the screw rod 43 either, but continue to make the pressing plate 34 move downward.,

[0022] Adopting the above scheme: Through the inclined plane transmission of the second spring 38 and the push block 310, the linear motion of the push ring 23 is converted into the radial clamping force of the pressing plate 34. The leaf picking can be completed without manual contact with the leaves, reducing sampling pollution. The push plate 33 and the pressing plate 34 are connected by a heteropolar magnet, which can not only ensure the transmission stability, but also overcome the magnetic force separation driven by the screw rod 43 to realize the independent downward movement and extrusion of the pressing plate 34, avoiding mechanical jamming. The two symmetrically distributed pressing plates 34 can fit branches with different diameters. The guide groove 15 and the insertion block of the top ring 39 cooperate to limit the movement track, ensuring the accuracy of the leaf scraping action and being applicable to various tree species.

[0023] The juice extraction component 4 includes a filter plate 41 fixedly arranged at the inner bottom end of the juice extraction cylinder 12. A plurality of groups of filter holes are uniformly and penetratingly formed in the filter plate 41, enabling the leaf juice to flow into the liquid storage cylinder 13. A linkage block 42 is rotatably connected to the bottom end of the filter plate 41. The top end of the linkage block 42 penetrates through the filter plate 41 and is fixedly connected to a screw rod 43 with a spiral groove formed on its outer cylindrical surface. The spiral groove formed on the outer cylindrical surface of the screw rod 43 is adapted to the guide block 36. A cross-shaped groove is formed at the bottom end of the linkage block 42, and a lifting groove 44 is formed at the bottom end of the screw rod 43. The lifting groove 44 is cross-shaped. A sleeve 45 is sleeved outside the screw rod 43. A cross-shaped insertion block is fixedly connected inside the sleeve 45. The cross-shaped insertion block is slidably inserted into the lifting groove 44. A crushing blade 46 is fixedly connected to the outside of the sleeve 45. There are six groups of crushing blades 46, which are evenly distributed on the outside of the sleeve 45. A receiving groove 47 is formed at the bottom end of the sleeve 45. The receiving groove 47 is cylindrical. A third spring 48 is fixedly connected to the inner top end of the receiving groove 47. One end of the third spring 48 is fixedly connected to the top end of the linkage block 42. The juice extraction component 4 further includes a motor 410 fixedly connected to the outer bottom end of the liquid storage cylinder 13. The output end of the motor 410 penetrates through the liquid storage cylinder 13 and is fixedly connected to a connecting rod 49. A cross-shaped convex block is fixedly arranged at the top end of the connecting rod 49, and the cross-shaped convex block at the top end of the connecting rod 49 is adapted to the cross-shaped groove at the bottom end of the linkage block 42. After the motor 410 is started, the connecting rod 49 at the output end drives the linkage block 42 to rotate through the cross-shaped convex block. The screw rod 43 at the top end of the linkage block 42 rotates synchronously. The screw rod 43 drives the sleeve 45 and the crushing blades 46 on the outside to rotate at a high speed through the cooperation of the lifting groove 44 and the cross-shaped insertion block, breaking the leaves scraped onto the filter plate 41. The juice flows into the liquid storage cylinder 13 through the holes of the filter plate 41. When the guide block 36 on the pressing plate 34 of the leaf picking component 3 is embedded into the spiral groove of the screw rod 43, the pressing plate 34 moves downward along the spiral groove, pushing the sleeve 45 to slide downward along the lifting groove 44. The third spring 48 is compressed and contracted. The pressing plate 34 squeezes the crushed leaves on the filter plate 41, further squeezing out the juice.

[0024] Adopting the above solution: First, the crushing blades 46 break the leaves to improve the juice release rate. The pressing plate 34 squeezes the crushed leaves, which can increase the juice collection amount compared with single crushing, ensuring the sufficiency of the detection sample. The sliding connection between the cross-shaped convex block and the groove, and the cross-shaped insertion block and the lifting groove 44 enables the sleeve 45 to not only rotate with the screw rod 43 but also move axially, compatible with the dual action requirements of crushing and squeezing. The motor 410 controls the timing of crushing and squeezing through forward and reverse rotation, and the entire process from crushing the leaves to juice extraction can be completed without manual intervention, reducing the complexity of the sampling operation. The threaded connection between the liquid storage cylinder 13 and the juice extraction cylinder 12 is convenient for disassembly and cleaning.

[0025] The working principle is as follows: When in use, first rotate the connecting frame 26 and tighten the nut 27 to adjust the holding container 1 and the telescopic rod 28 to an appropriate angle. Then, use the telescopic rod 28 to adjust the height of the holding container 1 so that the tree branches can be smoothly inserted into the container opening at the top of the leaf picking cylinder 11. Next, separate the telescopic rod 28 on the mounting ring 21 and the linkage ring 37, and drive the lifting member 311 to move until the lifting member 311 moves to the limit position. During this process, the push ring 23 moves upward under the guiding action of the guide post 22, pushing the linkage ring 37 to move along the axis of the leaf picking cylinder 11 towards the container opening direction, and at the same time driving the second spring 38, the top ring 39 and the push block 310 to move upward synchronously. During this process, the inclined surface of the push block 310 pushes the push plate 33 to slide towards the inside of the leaf picking cylinder 11, causing the first spring 32 to be stretched. The push plate 33 drives the pressing plate 34 to enter the leaf picking cylinder 11 from the slot 14 through the magnetic attraction of the magnetic block until the straight surfaces of the two semi-circular pressing plates 34 are in contact with the branches. After the pressing plate 34 is in contact with the branches, the linkage ring 37 continues to move upward, and the second spring 38 is compressed and contracted. At this time, move the holding container 1 to pull the branches outwards. During the extraction process, the pressing plate 34 scrapes the leaves on the branches into the juice extraction cylinder 12. While the leaf scraping operation is in progress, start the motor 410. The output end of the motor drives the linkage block 42 to rotate through the connecting rod 49. The linkage block 42 drives the screw rod 43 to rotate. The screw rod 43 drives the sleeve 45 and the crushing blades 46 to rotate synchronously through the cooperation of the lifting groove 44 and the cross-shaped insert block, crushing the leaves scraped onto the filter plate 41. The juice flows into the liquid holding cylinder 13 through the holes of the filter plate 41. When the branches completely leave the leaf picking cylinder 11, a moving space is generated between the two pressing plates 34. The compressed second spring 38 expands, pushing the top ring 39 to move upward until the top of the top ring 39 abuts against the bottom end of the mounting frame 31, causing the lifting member 311 to move to the limit position. At this time, stop separating the two telescopic rods 28. When the top ring 39 moves, it drives the push block 310, causing the pressing plate 34 to move towards the screw rod 43 until the guiding block 36 on the pressing plate 34 contacts the outer surface of the screw rod 43. As the screw rod 43 continues to rotate, when the guiding block 36 matches the spiral groove on the surface of the screw rod 43, the guiding block 36 inserts into the spiral groove. The pressing plate 34 moves downward under the guidance of the screw rod 43 against the magnetic attraction force with the push plate 33, pushing the sleeve 45 to slide down along the lifting groove 44. During the sliding process, the third spring 48 is compressed and contracted. The pressing plate 34 squeezes the crushed leaves on the filter plate 41 to further extract the juice. After the squeezing is completed, the motor 410 rotates in the reverse direction to drive the screw rod 43 to rotate in the reverse direction. The pressing plate 34 moves upward along the spiral groove, and the third spring 48 returns to its original state to push the sleeve 45 to reset. When the pressing plate 34 returns to the slot 14, it is reconnected to the push plate 33 through the magnetic block, and the motor 410 stops running. Finally, pull the telescopic rod 28 on the push ring 23. The push ring 23 moves towards the mounting ring 21. The linkage ring 37 loses the thrust, and the second spring 38 resets to push the linkage ring 37 to move downward. Then, the top ring 39 moves downward under the action of gravity, driving the push block 310 to move downward synchronously. Under the guiding of the inclined surface of the push block 310 and the reset pulling force of the first spring 32,The push plate 33 is reset and the pressure plate 34 is pulled out from the slot 14. At this time, the liquid container 13 is rotated to separate the threaded connection with the juice extraction cylinder 12, and the juice can be taken out. The juice extraction cylinder 12 is then rotated to separate the threaded connection with the leaf picking cylinder 11, so that the leaf residue can be cleaned. The sampling angle and height can be accurately adjusted by activating the part 2. Its articulated connection frame 26 cooperates with the nut 27 to adjust the angle of the container 1 to adapt to branches in different orientations such as tilted and vertical. The telescopic rod 28 supports height adjustment to ensure that the branches are accurately inserted from the container mouth. After separating the telescopic rod 28, the push ring 23 moves up along the guide column 22 to trigger the leaf picking action. The manual operating force is amplified by the inclined transmission of the spring 238 and the push block 310, which reduces the labor intensity of the sampler climbing or raising his arm. The T-shaped guide column 22 can also prevent the push ring 23 from getting off the track. The leaf picking part 3 is used to realize automatic leaf picking and precise positioning. The symmetrical pressing plate 34 is linked with the pushing plate 33 through the magnetic block. When the pushing block 310 moves up, the pressing plate 34 slides from the slot 14 into the leaf picking cylinder 11. The semicircular straight surface can fit the branches, so that the success rate of leaf scraping is improved. The pre-docking design of the guide block 36 and the spiral rod 43 enables the pressing plate 34 to automatically move to the juice extraction area after the leaves are picked. The transfer of the leaves from the leaf picking cylinder 11 to the filter plate 41 can be completed without additional operation, reducing the sample spillage caused by manual intervention. Through the juice extraction part 4, the full process automation of leaf crushing and juice squeezing is realized. The motor 410 drives the crushing blade 46 to rotate and crush the leaves. The filter plate 41 initially filters the juice. Then the pressing plate 34 moves down along the spiral groove to squeeze the broken leaves. The secondary juice extraction improves the total juice extraction rate. The sliding connection between the lifting groove 44 and the cross-shaped plug block enables the sleeve 45 to move axially during rotation and crushing. During maintenance, it is only necessary to unscrew the liquid storage cylinder 13 and the juice extraction cylinder 12 to clean the residue of the filter plate 41.
