Description

Technical Field

[0001] This utility model relates to the field of litter collection technology, and in particular to a litter stratification collector for the alpine tundra zone of Changbai Mountain. Background Technology

[0002] Litter collection is a core technology in the study of ecosystem material cycling and energy flow. It involves using specialized devices to capture organic matter such as fallen branches, leaves, fruits, and moss residues from surface vegetation, quantifying their input and compositional characteristics. The collected data allows for in-depth analysis of annual litter yield, seasonal variation patterns, and the return efficiency of key nutrients such as carbon, nitrogen, and phosphorus. This provides fundamental support for understanding ecosystem productivity, soil fertility maintenance mechanisms, and even assessing ecosystem responses to climate change. It is widely used in research on various terrestrial ecosystems, including forests, grasslands, and tundra. When research requires analyzing the dynamic patterns and nutrient cycling mechanisms of litter in the Changbai Mountain alpine tundra zone, and conventional collection methods cannot meet the specific needs, the Changbai Mountain alpine tundra litter stratification collector is required.

[0003] The Changbai Mountain alpine tundra litter stratifier is a specialized research device designed specifically for the region's low-temperature, strong-wind, and low-vegetation habitat. Its core function is to precisely capture litter of different particle sizes and decomposition stages through stratification. Based on lightweight, high-strength materials (such as a rust-resistant alloy frame and wear-resistant nylon mesh), this collector addresses the challenges of wind erosion and mixed-material composition in tundra litter. Its stratified design provides precise samples for subsequent analysis of litter composition, nutrient content, and decomposition rates, making it a crucial tool for studying carbon cycling, material return, and ecosystem function in the Changbai Mountain tundra. Common Changbai Mountain alpine tundra litter stratifiers rely on gravity or manual stratification to collect litter, leading to large accumulations, significant data bias, and reduced collection efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a litter stratification collector for the alpine tundra zone of Changbai Mountain. It aims to improve the problem that the existing litter stratification collectors for the alpine tundra zone of Changbai Mountain can only collect litter in layers by gravity or manual labor when the litter is left to stand still, which leads to a large accumulation of litter, resulting in large deviations in the collection data and reduced collection efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A litter stratification collector for the alpine tundra zone of Changbai Mountain includes a mounting frame. A first rotating shaft is rotatably connected to the inner wall of the mounting frame. A first rotating plate is fixedly connected to the outer wall of the first rotating shaft. A second rotating shaft is fixedly connected to the inside of the first rotating plate. A second rotating plate is rotatably connected to the outer wall of the second rotating shaft. A round rod is rotatably connected to the inside of the second rotating plate. The outer wall of the round rod is slidably connected to the inside of the mounting frame. A fixing frame is fixedly connected to the outer wall of the round rod. A first sieve frame is fixedly connected to the outer wall of the fixing frame. A driving assembly is fixedly installed on the inner wall of the mounting frame. The driving assembly is used to drive the first rotating plate to swing.

[0007] Preferably, the drive assembly includes a motor, the outer wall of which is fixedly connected to the inner wall of the mounting bracket, and a third rotating plate is eccentrically disposed at the output end of the motor. A cylinder is rotatably connected inside the third rotating plate, and the outer wall of the cylinder is fixedly connected to the inside of the first rotating plate.

[0008] Preferably, a second screen frame is fixedly connected to the inner bottom wall of the mounting frame.

[0009] Preferably, a square tube is fixedly connected to the lower surface of the mounting bracket, and a third rotating shaft is rotatably connected inside the square tube.

[0010] Preferably, a crank handle is fixedly connected to the outer wall of the third rotating shaft, and a first bevel gear is fixedly connected to the outer wall of the third rotating shaft.

[0011] Preferably, the teeth of the first bevel gear are meshed with a second bevel gear, and the bottom end of the second bevel gear is fixedly connected with a threaded rod.

[0012] Preferably, the outer wall of the threaded rod is threadedly connected to a hollow column, and the outer wall of the hollow column is slidably connected to the inside of the square tube.

[0013] Preferably, a base plate is fixedly connected to the lower surface of the hollow column, and a caster wheel is fixedly connected to the lower surface of the base plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the third rotating plate is driven to rotate eccentrically by a motor. The eccentric rotation of the third rotating plate causes the round rod to shake up and down. The shaking of the round rod causes the first screen frame to shake up and down. Furthermore, the different mesh densities of the two first screen frames enable the litter to be automatically collected in layers, thereby improving the accuracy and efficiency of litter collection in the alpine tundra zone of Changbai Mountain.

[0016] 2. In this utility model, the third rotating shaft is driven to rotate by shaking the handle, and the rotation of the third rotating shaft drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded rod to move upward through the hollow column, and the upward movement of the threaded rod drives the mounting frame to move upward, thereby raising the mounting frame to be used away from obstacles. This reduces the interference of the complex surface environment of the Changbai Mountain alpine tundra zone on the collection and improves the flexibility of the device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3An embodiment of this utility model provides a layered collector for litter in the alpine tundra zone of Changbai Mountain, comprising a mounting frame 1, a first rotating shaft 2 rotatably connected to the inner wall of the mounting frame 1, a first rotating plate 3 fixedly connected to the outer wall of the first rotating shaft 2, a second rotating shaft 4 fixedly connected to the inside of the first rotating plate 3, a second rotating plate 5 rotatably connected to the outer wall of the second rotating shaft 4, a round rod 6 rotatably connected to the inside of the second rotating plate 5, the outer wall of the round rod 6 slidably connected to the inside of the mounting frame 1, a fixed frame 7 fixedly connected to the outer wall of the round rod 6, a first sieve frame 8 fixedly connected to the outer wall of the fixed frame 7, and a driving assembly fixedly provided on the inner wall of the mounting frame 1, the driving assembly being used to drive the first rotating plate 3 to swing.

[0026] Specifically, the first rotating plate 3 is driven to swing back and forth by the drive component. The swing of the first rotating plate 3 drives the second rotating plates 5 on both sides to rotate and move through the second rotating shaft 4. The mounting frame 1 has holes inside, which allows the round rod 6 to slide inside the mounting frame 1. Therefore, the movement of the second rotating plates 5 on both sides drives the round rod 6 to shake up and down. The round rod 6 fixes the fixing frame 7. The up and down shaking of the round rod 6 drives the fixing frame 7 to shake up and down. The up and down shaking of the fixing frame 7 drives the two first sieve frames 8 to shake up and down. The screen mesh of the upper first sieve frame 8 has a lower mesh density, which can screen out larger litter, such as fruits and robust herbaceous plant remains. The shaking of the upper first sieve frame 8 removes the larger litter and screens it into the lower first sieve frame 8. The lower first sieve frame 8 screens out smaller litter, such as broken leaf fragments and reproductive remains. The shaking of the first sieve frame 8 makes the stratification of litter more thorough, thereby improving the accuracy and efficiency of litter collection in the alpine tundra zone of Changbai Mountain.

[0027] Reference Figures 1-3 The drive assembly includes a motor 9, the outer wall of which is fixedly connected to the inner wall of the mounting bracket 1. The output end of the motor 9 is eccentrically provided with a third rotating plate 10, and a cylinder 11 is rotatably connected inside the third rotating plate 10. The outer wall of the cylinder 11 is fixedly connected to the inside of the first rotating plate 3.

[0028] Specifically, the motor 9 is fixed by the mounting bracket 1, the motor 9 drives the third rotating plate 10 to rotate eccentrically, the rotation of the third rotating plate 10 drives the cylinder 11 to rotate, and the rotation of the cylinder 11 drives the first rotating plate 3 to swing back and forth.

[0029] Reference Figure 1 and Figure 2 The inner bottom wall of the mounting frame 1 is fixedly connected to a second screen frame 21, and the lower surface of the mounting frame 1 is fixedly connected to a square tube 12. The inside of the square tube 12 is rotatably connected to a third rotating shaft 13.

[0030] Specifically, the second screen frame 21 is fixed by the mounting frame 1. By shaking the first screen frame 8, the fallen material is screened layer by layer, and smaller fallen material is screened into the interior of the second screen frame 21. The fallen material can be drained of water through the second screen frame 21. The four square tubes 12 on the lower surface are fixed by the mounting frame 1.

[0031] Reference Figure 4 and Figure 5 A crank handle 14 is fixedly connected to the outer wall of the third rotating shaft 13. A first bevel gear 15 is fixedly connected to the outer wall of the third rotating shaft 13. A second bevel gear 16 is meshed with the tooth end of the first bevel gear 15. A threaded rod 17 is fixedly connected to the bottom end of the second bevel gear 16.

[0032] Specifically, the crank handle 14 is fixed by the third rotating shaft 13. Turning the crank handle 14 drives the third rotating shaft 13 to rotate. The rotation of the third rotating shaft 13 drives the first bevel gear 15 to rotate. The rotation of the first bevel gear 15 drives the second bevel gear 16 to rotate. The rotation of the second bevel gear 16 drives the threaded rod 17 to rotate.

[0033] Reference Figure 5 The outer wall of the threaded rod 17 is threadedly connected to a hollow column 18. The outer wall of the hollow column 18 is slidably connected to the inside of the square tube 12. The lower surface of the hollow column 18 is fixedly connected to a base plate 19, and the lower surface of the base plate 19 is fixedly connected to a caster wheel 20.

[0034] Specifically, when the threaded rod 17 rotates, it can be moved by the hollow column 18. The movement of the threaded rod 17 drives the square tube 12 to move, which in turn changes the distance between the square tube 12 and the hollow column 18, thus changing the height of the mounting frame 1. This allows the mounting frame 1 to be used even when there are obstacles such as rocks or bushes on the ground, achieving the effect of improving the flexibility of the lifting device.

[0035] Working principle: When the device is needed, the motor 9 is started, which drives the third rotating plate 10 to rotate eccentrically. The eccentric rotation of the third rotating plate 10 drives the first rotating plate 3 to swing back and forth via the first rotating shaft 2 through the cylinder 11. This swinging motion of the first rotating plate 3 drives the second rotating plates 5 on both sides to rotate and move via the second rotating shaft 4. The movement of the second rotating plates 5 causes the round rod 6 to vibrate up and down. This vibration of the round rod 6, through the fixed frame 7, causes the two first screen frames 8 to vibrate up and down. The upper first screen frame 8 has a lower mesh density, screening out larger debris, for example... If the robust remains of herbaceous plants are indeed collected, the litter is sifted out into the lower first sieve 8 by shaking the upper first sieve 8. Smaller litter, such as broken leaf fragments and propagation remains, are sifted out. The lower first sieve 8 shakes even smaller litter, such as tiny leaf fragments and fine fragments of lichen or moss, into the second sieve 21. The second sieve 21 then removes the moisture. By shaking the first sieve 8, the litter is stratified and sifted more thoroughly, thereby improving the accuracy and efficiency of litter collection in the alpine tundra zone of Changbai Mountain.

[0036] When there are obstacles such as rocks or bushes on the ground at the collection point, crank the handle 14 to make the third shaft 13 rotate. The rotation of the third shaft 13 drives the first bevel gear 15 to rotate, which in turn drives the second bevel gear 16 to rotate. The rotation of the second bevel gear 16 drives the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the hollow column 18 to move the threaded rod 17 upward. The upward movement of the threaded rod 17 drives the square tube 12 upward. The upward movement of the square tubes 12 on all sides causes the mounting frame 1 to move upward. The mounting frame 1 is then raised to move away from obstacles such as rocks or bushes, so that the device can be used when there are obstacles on the ground. This reduces the interference of the complex surface environment of the Changbai Mountain alpine tundra zone on litter collection and improves the flexibility of the device.

[0037] This device can not only automatically shake the first sieve 8 to make the stratification of litter more thorough, thereby improving the accuracy and efficiency of litter collection in the Changbai Mountain alpine tundra zone, but also raise the mounting frame 1 to be used away from obstacles such as rocks or bushes, thereby reducing the interference of the complex surface environment of the Changbai Mountain alpine tundra zone on litter collection and improving the flexibility of the device.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
