Description

Technical Field

[0001] The present application relates to the technical field of litter sampling, and in particular to a litter collection and sampling device for forest environment monitoring. Background Art

[0002] In forest ecosystems, monitoring litter is essential for understanding forest growth, biodiversity, and ecosystem health. Traditional litter collection sampling generally uses a net frame collection method, which usually consists of a series of containers or net structures fixed to the ground to collect naturally falling materials. Although this method works well in some cases, its shortcomings are particularly obvious in humid or rainy environments.

[0003] A major problem with static litter collection nets is that they easily accumulate water, especially during the rainy season, which can result in excessive humidity in the collected litter samples. High moisture content not only increases the error in sample weight measurement, but can also cause microbial growth and corruption, affecting sample quality and the accuracy of subsequent analysis. In addition, the moisture in the collection net may react with chemical reagents, interfering with the subsequent chemical analysis process.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0034] Embodiment 1

[0035] like Figure 1-Figure 10 As shown, a litter collection and sampling device for forest environment monitoring proposed in one embodiment of the present application includes:

[0036] A mounting seat 1 is provided with a connecting rod 2 on the top of the mounting seat 1, a mounting frame 3 is provided on the top of the connecting rod 2, a connecting frame 4 is provided on the top of the mounting frame 3, the top of the connecting frame 4 is open and a collecting frame 5 is provided with a horizontal sliding installation, specifically, rollers are provided on two opposite sides of the length direction of the collecting frame 5, a slide groove for the rollers to roll is provided inside the connecting frame 4, and the use of rollers can reduce the friction resistance of the collecting frame 5 when it moves, so that the collecting frame 5 moves more smoothly, and a collecting net 8 is provided inside the collecting frame 5, and the collecting net 8 is used to receive litter;

[0037] The water storage mechanism 6 comprises a water storage chamber 601 constructed on the mounting frame 3, a drain pipe 602 connected to the bottom of the water storage chamber 601 is vertically mounted on the mounting frame 3, and a plugging member 603 for plugging the drain pipe 602 is mounted on the drain pipe 602. Specifically, a thread is provided at the free end of the drain pipe 602, and the plugging member 603 can be an existing threaded cover. When the mounting seat 1 is mounted at the corresponding position, water can be poured into the water storage chamber 601, and then the dripping amount can be controlled by controlling the tightening degree of the threaded cover. Preferably, the plugging member 603 can also be a device for controlling the water output of the water pipe, such as a ball valve, a flow restrictor faucet, etc.;

[0038] The vibration mechanism 7 includes a floating plate 701 vertically slidably installed in the water storage chamber 601, and a linkage assembly 702 acting on the floating plate 701 and the collecting net 8 is installed on the mounting frame 3. When the floating plate 701 moves vertically, the collecting net 8 is driven to vibrate horizontally through the linkage assembly 702. That is to say, when the drain pipe 602 is dripping, the water level in the water storage chamber 601 will drop, and the floating plate 701 will move downward. As the floating plate 701 drops, the collecting net 8 will vibrate horizontally through the linkage assembly 702, which will also drive the collecting frame 5 to vibrate, so that the litter on the collecting net 8 shakes on the collecting net 8, effectively preventing excessive water accumulation on the collecting net 8, reducing the moisture on the litter, preventing the error of the sample weight measurement caused by excessive humidity of the litter, and reducing the impact of excessive moisture on the quality of the litter sample and the accuracy of subsequent analysis.

[0039] like Figure 3 As shown, in embodiment 1, the linkage assembly 702 includes a transmission gear 7021 rotatably mounted on the mounting frame 3, a mounting plate 7022 is vertically mounted on the top of the floating plate 701, and a driving rack 7023 meshing with the transmission gear 7021 is mounted on one side of the mounting plate 7022. A transmission member 9 acting on the transmission gear 7021 and the collecting net 8 is rotatably mounted on the mounting frame 3. When the transmission gear 7021 rotates, the collecting net 8 is driven to vibrate horizontally through the transmission member 9. That is to say, when the floating plate 701 moves downward, the movement of the floating plate 701 will indirectly drive the mounting plate 7022 to move downward. When the mounting plate 7022 moves downward, it will drive the driving rack 7023 to move downward, thereby causing the transmission gear 7021 to rotate. At this time, the horizontal vibration of the collecting net 8 is realized through the transmission member 9. By converting the vertical movement of the floating plate into rotational power, the vibration of the collecting net 8 is realized in cooperation with the transmission member 9, and the power generated by the displacement of the floating plate is fully utilized.

[0040] like Figure 3 and Figure 4As shown, the transmission member 9 includes a rotating disk 901 rotatably mounted on the mounting frame 3, two toggle plates 902 are configured on the outer peripheral side of the rotating disk 901, a transmission belt assembly 903 is installed between the transmission gear 7021 and the rotating disk 901, the transmission belt assembly 903 is an existing belt member, the transmission gear 7021 and the rotating disk 901 are both installed with pulleys, a transmission belt is installed between the two pulleys, and also includes a transmission rod 904 rotatably mounted on the mounting frame 3 at one end, and the rotating disk 901 is located at Below the transmission rod 904 and close to the position of the rotation axis of the transmission rod 904, the transmission rod 904 is normally pressed on the rotating disk 901 due to the effect of gravity. In this way, when the rotating disk 901 rotates, the toggle plate 902 lifts the transmission rod 904, and the free end of the transmission rod 904 has a larger rotation range. The free end of the transmission rod 904 is constructed with an extension rod 905. The free end of the extension rod 905 passes through the connecting frame 4 and is hinged with a hinge rod 906. The free end of the hinge rod 906 is hinged on the collecting net 8, that is, Specifically, when the transmission gear 7021 rotates, the transmission belt assembly 903 drives the rotating disk 901 to rotate. When the rotating disk 901 rotates, the toggle plate 902 constructed on the rotating disk 901 rotates. After the toggle plate 902 contacts the transmission rod 904, the toggle plate 902 is lifted up. The lifted transmission rod 904 drops down due to the action of gravity as the toggle plate 902 is separated from the transmission rod 904. Because the free end of the transmission rod 904 is constructed with an extension rod 905, the extension rod 905 05 is hinged with a hinged rod 906, so the collection net 8 can be horizontally reciprocated by the extension rod 905 through the hinged rod 906 when it is rotated, thereby realizing vibration. The design of the extension rod 905 further increases the rotation amplitude, so that the extension rod 905 can be moved in a large amplitude when the transmission rod 904 is rotated in a small amplitude, and the collection net 8 can be horizontally reciprocated in cooperation with the hinged rod 906, thereby increasing the amplitude of the horizontal reciprocating movement of the collection net 8, thereby further improving the vibration effect of the collection net 8.

[0041] Embodiment 2

[0042] like Figure 3 , Figure 4 and Figure 5As shown, this embodiment further improves the present application on the basis of the first embodiment. The wall thickness of the connecting frame 4 is hollow and the top is inclined. A plurality of water inlet holes 10 connected to the hollow wall thickness are evenly provided on the top of the connecting frame 4. A water inlet groove 11 is provided on the mounting frame 3. One end of the water inlet groove 11 is connected to the water storage chamber 601, and the other end is connected to the bottom of the connecting frame 4. A through groove 12 is provided on the top of the floating plate 701. That is to say, when it rains in the forest, part of the rainwater will pass through the water inlet hole 10 into the hollow wall thickness of the connecting frame 4, and then flow into the water inlet groove 11 due to the action of gravity, and finally enter the top of the floating plate 701. Because the floating plate 701 is provided with a through groove 12, the rainwater will pass through the through groove 12 and flow into the bottom of the floating plate 701, thereby causing the water level in the water storage chamber 601 to rise. After the mounting base 1 is installed, there is no need to pour water into the water storage chamber 601, and the staff does not need to carry too much water, which not only saves the labor of the staff but also saves water resources. Specifically, an overflow port is provided on the mounting frame 3. When the water level in the water storage chamber 601 rises and the floating plate 701 moves to the highest point, the excess water will flow into the outside from the overflow port, and the rising water level in the water storage chamber 601 will drive the floating plate 701 to move upward. Therefore, at this time, the driving rack 7023 will also drive the transmission gear 7021 to rotate, thereby also driving the collection net 8 to vibrate, preventing excessive water from accumulating on the collection net 8. When the rain stops, the water level inside the water storage chamber 601 drops, which can make the collection net 8 vibrate, thereby shaking off the accumulated water accumulated on the fallen leaves of the collection net 8 to reduce the moisture content of the fallen leaves of the collection net 8.

[0043] Embodiment 3

[0044] like Figure 3-Figure 5 As shown, this embodiment further improves the present application on the basis of the second embodiment, the connecting frame 4 is in an inverted cone shape, so that when rainwater enters the thick wall of the connecting frame 4, it can prevent rainwater from accumulating in the connecting frame 4, ensuring that rainwater can enter the water storage chamber 601, and a sealing plate 13 is constructed near the top of the connecting frame 4, and a chute 14 is horizontally opened on the sealing plate 13, and a convex rod 15 passing through the chute 14 is vertically constructed at the bottom of the collecting net 8, that is, the water on the fallen leaves will flow into the sealing plate 13 due to the vibration of the collecting net 8, and then pass through the The water flows downward through the chute 14, the hinged rod 906 is hinged on the convex rod 15, and a drainage frame plate 16 is inclined inside the connecting frame 4. A drainage groove 17 is provided on the connecting frame 4, and the lowest end of the drainage frame plate 16 is located in the drainage groove 17. The drainage frame plate 16 is located below the chute 14, and a slot 18 is provided on the connecting frame 4 for the extension rod 905 to pass through. In other words, the water flowing out of the chute 14 will be received by the drainage frame plate 16, and then flow to the outside along the inclined direction of the drainage frame plate 16, so as to prevent a lot of water from being retained in the connecting frame 4.

[0045] Embodiment 4

[0046] like Figure 3-Figure 5 As shown, this embodiment further improves the present application on the basis of embodiments one to three, a push block 19 is horizontally slidably installed on the mounting frame 3, and a pneumatic component 20 for driving the push block 19 to move horizontally is installed on the mounting frame 3, and the push block 19 is located below the transmission rod 904, and when the push block 19 hits the transmission rod 904, the transmission rod 904 rotates in the direction away from the rotating disk 901, and when the wind blows in the forest, the pneumatic component 20 will move the push block 19, so that the push block 19 hits the transmission rod 904, and the transmission rod 904 rotates in the direction away from the rotating disk 901, and then the transmission rod 904 will contact the rotating disk 901 due to the action of gravity, so that the transmission rod 904 reciprocates a stroke to realize the reciprocating movement of the collecting net 8, and the reciprocating vibration of the collecting net 8 can also be realized by wind when there is no water in the water storage chamber 601.

[0047] like Figure 8-Figure 10 As shown, in the fourth embodiment, the pneumatic assembly 20 includes an arc-shaped convex plate 2001 installed on the mounting frame 3, an arc-shaped cavity 2002 is constructed in the arc-shaped convex plate 2001, a moving block 2003 is slidably installed in the arc-shaped cavity 2002, the arc surface of the arc-shaped convex plate 2001 faces upward and is provided with a through slot 2004, a pull rope 2005 is connected to the connecting frame 4, a through hole 2006 is provided at the top of the push block 19, and a shielding through slot 2004 is slidably installed on the arc surface of the arc-shaped convex plate 2001. The free end of the pull rope 2005 passes through the through hole 2006, the through slot 2004 and the movable baffle 2008 in sequence to connect with the movable block 2003. The outer arc surface of the arc-shaped convex plate 2001 is symmetrically connected with two ventilation pipes 2007, and the two ventilation pipes 2007 are coaxial. In a normal state, the pull rope 2005 is vertically downward due to the weight of the movable block 2003, and the movable block 2003 is located at the lowest position of the arc cavity 2002. When the wind blows, the wind enters the arc cavity 2002 from one of the ventilation pipes 2007, and then flows out from the other ventilation pipe 2007. In this process, the movable block 2003 will swing in the arc cavity 2002 under the action of wind force, thereby driving the movable baffle 2008 to move. The design of the movable baffle 2008 can prevent the wind from flowing out of the through groove 2004, ensuring the flow of wind and ensuring that the movable block 2003 can be moved by the wind. The movement of the movable block 2003 will cause the pull rope 2005 to shake. During the shaking process, the pull rope 2005 will indirectly drive the movement of the push block 19, so that the push block 19 hits the transmission rod 904 to realize the rotation of the transmission rod 904. The design of the pull rope 2005 can effectively reduce the weight, so that the movable block 2003 will move more when pushed by the wind, ensuring that the push block 19 can drive the transmission rod 904 to rotate after hitting the transmission rod 904.

[0048] Embodiment 5

[0049] like Figure 6-Figure 10 As shown, this embodiment further improves the present application on the basis of the fourth embodiment. The two ends of the ventilation pipe 2007 that are far away from each other are connected to a trumpet-shaped air inlet cover 21, and a filter screen 22 is installed at the opening of the air inlet cover 21. The trumpet-shaped air inlet cover 21 further increases the flow rate of the wind when the wind enters the air inlet cover 21 and passes through the ventilation pipe 2007 when it is windy, thereby increasing the power of the pushing block 19. The design of the filter screen 22 effectively prevents foreign matter from entering the ventilation pipe 2007.

[0050] like Figure 6-Figure 10 As shown, in the fifth embodiment, the two ends of the arc-shaped convex plate 2001 that are away from each other are installed with the first magnetic block 23, and the two ends of the moving block 2003 that are opposite to each other are installed with the second magnetic block 24. The second magnetic block 24 and the opposite surface of the first magnetic block 23 repel each other. When the wind drives the moving block 2003 to move, the movement of the moving block 2003 will drive the first magnetic block 23 to move, so that one of the first magnetic blocks 23 moves toward the opposite second magnetic block 24. When the first magnetic block 23 approaches the opposite second magnetic block 24, a reaction force is generated due to the mutual repulsion of magnetic attraction, thereby increasing the swing amplitude of the pull rope 2005. After the wind force gradually decreases, the pull rope 2005 will continue to swing for a period of time due to the repulsive force generated by the first magnetic block 23 and the second magnetic block 24. When the wind force is sufficient, the excess power will make the first magnetic block and the opposite second magnetic block 24 closer, so that when the wind stops, the pushing block 19 can continue to hit the transmission rod 904 for a period of time, thereby improving the utilization effect of the wind force.

[0051] Embodiment 6

[0052] like Figure 4 and Figure 6 As shown, this embodiment further improves the present application on the basis of the fifth embodiment, the connecting rod 2 is rotatably mounted on the mounting seat 1 through a bearing, a weather vane 25 is horizontally mounted on the outer side of the connecting frame 4, and a tail wing 26 is mounted on the side of the connecting frame 4 away from the wind vane 25. That is to say, when the wind blows, in order to ensure that the ventilation pipe 2007 is consistent with the direction of the wind, the wind will be blown to the tail wing 26 through the tail wing 26, thereby driving the connecting rod 2 to rotate until it is consistent with the wind direction, which is similar to the principle of a weather vane, thereby improving the efficiency of wind utilization.

[0053] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
