The specific meaning of the above terms in the embodiments of the present utility model will be understood by those of ordinary skill in the art according to specific circumstances. Furthermore, the meaning of "plurality" is two or more. The specification "and/or" indicates at least one of the connected objects, and the character "/", generally indicates that the associated object is an "or" relationship.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The existing litter collecting device mainly comprises a frame, a mesh bag, ropes, support legs and the like. The frame plays a main body supporting role and is often composed of a metal or wooden rod-shaped material; the mesh bag is used for collecting falling objects, is usually made of mesh materials such as nylon and plastics, has a pore diameter of about 0.1cm-2cm, is mainly fixed on a frame, and is sometimes provided with a binding rope at a mesh port for closing up and preserving after sampling. The net bag is connected below the frame, the frame is fixed on the ground through the support legs, and the bottom of the net bag is connected with the frame through ropes sometimes, so that the net bag is fixed and not lifted by strong wind.

When dynamically monitoring litters in wild forests, the adoption of a litters collecting frame is the most reliable and most commonly used means. However, the current devices often have the following problems: 1. the size and the height of the collecting frame are difficult to adjust, the collecting frame cannot adapt to forests with different densities, and meanwhile, the whole structure cannot be folded, so that the portability is low; 2. the collecting net is shallow and is not scientific enough to arrange, and a reverse blocking device is absent, so that the collected litters entering the net are easy to blow out in windy weather; 3. the general collection device lacks the weighing record system that does not receive the influence of precipitation, can't realize the real-time supervision record of litter weight, only collect the frequency with the people and be difficult to satisfy the experiment demand.

An embodiment of the present utility model provides a litter collection device, and referring to fig. 1 and 2, the litter collection device includes a frame body 100 and a collection net 200.

In the litter collection device, the frame 100 mainly plays a role of supporting the collection net 200. The material of the frame body 100 can be made of some materials with higher hardness and lighter weight, such as aluminum alloy, so that the litter collecting device can be convenient for carrying and transferring of staff while meeting certain supporting performance. It should be noted that the size of the rack 100 is not particularly limited, and may be designed according to the density of the plants. In order to facilitate movement of the litter collection device, a movement wheel may be provided at the bottom of the frame 100. The moving wheel can be electric or pushed by manpower. When the moving wheels are pushed by manpower, the first two moving wheels of the moving direction of the frame body 100 can be set as universal wheels. A buffer sleeve or a recess portion conforming to the hand characteristics of the human body may be provided on the frame body 100 at the hand holding portion. Thus, the working personnel can feel more comfortable in the actual pushing process.

In some possible embodiments, various weather conditions, such as sun, storms, etc., are encountered as litter collection devices are most often performed in the field. In order to better prolong the service life of the litter collection device, paint or the like can be painted on the outer side of the rack body 100 to prevent the litter collection device from rusting or reduce damage to the litter collection device caused by sunburn. Meanwhile, considering the inconvenience of night work or inconvenient searching at night, a fluorescent label can be arranged on the frame body 100, so that a worker can search the fluorescent label more accurately and conveniently at night.

In the litter collection device, the collection net 200 has a main function of intercepting and capturing litter. Also, because the collection web 200 is characterized by a softer texture, it cannot be formed on its own. Therefore, the collection net 200 is provided to the frame body 100, and the frame body 100 supports and forms the collection net. In order to make the collection net 200 collect litter better, the top end of the collection net 200 is provided with an open shape, and the bottom of the collection net may be closed or open. When the bottom end of the frame body 100 is open, the bottom of the collecting net 200 needs to be provided with a cavity for receiving the falling objects, so that the falling objects can be collected, and the collected falling objects can be subjected to the next operation. In some possible embodiments, in order to facilitate the connection between the frame 100 and the collecting net 200, a plurality of sliding rings may be slidably disposed on the frame 100, and a plurality of hooks may be disposed on the top end of the collecting net 200, where when the two are required to be connected, the hooks may be directly hooked on the sliding rings. While the degree of stretching of the collection mesh 200 can also be adjusted by sliding the slip ring.

To prevent litter that has been collected on the collection net 200 from escaping the collection net 200 under other factors such as wind, a backstop 300 may be provided on the collection net 200. Specifically, the backstop 300 is disposed in the middle of the collecting net 200, dividing the collecting net 200 into upper and lower parts. The check member 300 and the bottom of the collecting net 200 form a cavity, and the bottom of the cavity gradually contracts to the check member 300 to lock the collected objects inside the cavity. At the same time, the backstop 300 forms a funnel with the top of the collection net 200. The litter falls into the upper half of the collection mesh 200 and slides into the receptacle. And because the upper port of the containing cavity is smaller, litters falling into the containing cavity are not easy to go out from the containing cavity, so that the litters in the containing cavity are locked.

Experiments show that when the fully-opened collecting net 200 without the non-return element 300 is used for collecting the Chinese pine withers, the dry weight of the Chinese pine withers is 48.64g in average all the year round, wherein the dry weight of the blades is 41.79g in average; the average dry weight of the litters of the cork oak in each month is 54.18g, wherein the average dry weight of the blades is 39.23g. The average dry weight of the litters in each month of the whole year is 55.88g when the litters are collected, the total loss of the litters is reduced by 14.88%, the dry weight of the leaves is 48.54g, and the loss of the leaves is reduced by 16.15%. The dry weight of the litters of the cork oak in each month is 62.94g averagely, the total loss of the litters is reduced by 16.17%, the dry weight of the blades is 46.45g, and the loss of the blades is reduced by 18.40%.

Specifically, the support assembly 120 is provided with four. In this embodiment, the annular body is rectangular. Specifically, the four supporting components 120 are disposed at the bottoms of the four corners of the ring body in a one-to-one correspondence manner, so as to support the ring body. In order to facilitate the carrying of the litter collection device, the support assembly 120 is rotatably connected to the ring body, so that the support assembly 120 can be supported when the litter collection device needs to be used; when it is desired to move or carry it, the support assembly 120 can be folded up, thereby reducing its size. In order to fix the support assembly 120 when supporting, a limiting block may be further disposed at a connection portion between the support assembly 120 and the annular body, and when the support assembly 120 supports, the limiting block prevents further rotation, and it should be noted that an included angle between the support assembly 120 and the annular body is an obtuse angle. To facilitate insertion of support assembly 120 into the ground, a pointed leg 125 may be provided at the bottom of support assembly 120.

Embodiments of the carrier assembly 110 are provided below.

Referring to fig. 3, the carrier assembly 110 includes a first carrier 111 and a second carrier 113, and a first adjusting member 112 is disposed between the first carrier 111 and the second carrier 113, and the first adjusting member 112 is used for adjusting the size of the carrier assembly 110. Specifically, the first bearing member 111 and the second bearing member 113 are connected in a mutually inserted manner, and the first adjusting member 112 is fixedly mounted on the first bearing member 111 or the second bearing member 113. When the first bearing member 111 and the second bearing member 113 are plugged, the first bearing member 111 and the second bearing member 113 first pass through the first adjusting member 112, the first adjusting member 112 is provided with a plug, the first bearing member 111 and the second bearing member 113 are provided with a jack, and the plug on the first adjusting member 112 can fix the first bearing member 111 and the second bearing member 113 when penetrating the jack. When the length of the bearing assembly 110 needs to be adjusted, the pins on the first adjusting member 112 can be pulled out, then the first bearing member 111 and the second bearing member 113 are stretched, and after the first bearing member 111 and the second bearing member 113 are stretched in place, the pins are reinserted into the jacks to achieve fixation. Corresponding operations are performed on the plurality of bearing assemblies 110 so as to realize adjustment of the size of the annular body.

The stabilizer 124 may improve stability of the litter collection device, prevent the support assembly 120 from skewing and shifting in the soil, and maintain the receiving opening of the ring always horizontal. Because the study on the slope forest land shows that the whole litter collecting device can be inclined downwards along the slope due to the action of gravity, and even can be turned over under the action of slope runoff, wind power and the like. When the gradient is 20-30 degrees, the existing collecting device with unadjustable frame legs can displace or even turn sideways at 33.33 percent, and the litter collecting device completely avoids the deflection and displacement along the slope, the stabilizing piece 124 compacts the soil at the tip supporting angle 125, the friction between the tip supporting angle 125 and the soil is increased, the litter receiving surface is always kept horizontal, and the receiving effect is kept stable.

In practical applications, the tip angle 125 needs to be inserted into the earth, i.e., the tip angle 125 will be buried in the earth. The buried portion may still be skewed or displaced, so the addition of the stabilizing members 124 of the present utility model may improve the stability of the ground portion. In some possible embodiments, the stabilizer 124 may be circular, rectangular, regular polygon, etc.

An embodiment of the weighing unit 400 is provided below.

Referring to fig. 1 and 3, the litter collection apparatus further includes a weighing member 400, the weighing member 400 being disposed below the collection net 200. The weighing unit 400 includes a weigh frame 410 and a weigh body 420 connected to each other, the weigh frame 410 carrying the collection, the weigh body 420 weighing the collection, and the weight change recorded. The litters in the collection net 200 are collected at regular intervals and brought back to the laboratory for analysis of the composition and natural water content, so that the littering dynamics of the litters are monitored. In the process of weighing litters, great influence of rainfall on the weight of the litters is difficult to avoid. Because the rain water trapped by the falling objects is mainly composed of two parts: 1. water absorbed by the litter; 2. water adhering to the surfaces of the litters. Some of the attached water drops under the action of gravity, so that the influence of the gravity water on the weight of the litters needs to be eliminated, and the weight of the litters is eliminated in time in the weighing process. Therefore, the weighing frame 410 is provided with a hollow portion for draining the moisture between the falling objects.

When weighing is performed in rainy days, the weight of the litter in the collection net 200 is continuously increased due to the water retention effect of the litter. However, as the duration of rainfall increases, the interception capacity gradually reaches a saturated state, and the rainfall contacted by the falling matters in the collection net 200 generates vertical flow under the action of gravity and forms a stable flow path. The vertical runoff is discharged through the hollowed-out portion of the weigh frame 410, during which time the asymmetric weighing means 400 is affected, leaving only the litter trapped moisture within the weighing range. Therefore, the dynamic change of the dry weight of the litters and the natural water content is mainly weighed and recorded in sunny days, and the dry weight of the litters, the natural water content and the interception rainfall are mainly recorded in rainy days.

An embodiment of the flow directing member 500 is provided below.

When weighing the litters in rainy days, in order to avoid the influence of rainwater on the weighing result, the litters collecting device further comprises a flow guiding component 500. The diversion component 500 is arranged below the hollowed-out part and is used for diversion of rainwater. The flow guiding component 500 includes a flow guiding assembly 510 and a flow guiding supporting assembly 520 connected to each other, and the flow guiding supporting assembly 520 is used for supporting the flow guiding assembly 510. The flow guiding component 510 comprises a funnel 511 and a drainage tube 512 which are mutually communicated, the funnel 511 is positioned under the hollowed-out part, is aligned to litters collected by the collecting net 200, and is used for completely collecting and draining vertical product flows in the rainfall process, so that weighing results are prevented from being influenced. The draft tube 512 is connected to a draft support assembly 520. The flow guiding support assembly 520 comprises a slider 521 and a support bar 522, the slider 521 is slidably disposed on the support bar 522, and a limiting member is disposed between the slider 521 and the support bar 522. In particular, the stop may be a latch. When it is desired to fix the slider 521 and the support bar 522, a latch may be inserted between the slider 521 and the support bar 522. The slider 521 is connected to the flow directing assembly 510, and in particular, the slider 521 is connected to the draft tube 512.

The diversion member 500 does not generate a large difference in fresh weight in sunny days, but a large deviation in fresh weight weighing occurs in rainy days. In the test, when the rainfall is less than 20mm, the short-time deviation of the fresh weight of the diversion component 500 in the rainfall process can reach 245g-490g without setting the diversion component 500, and the deviation is only 4.9g-73.5g; when the rainfall is 20-60 mm, the short-time deviation of fresh weight of the diversion component 500 in the rainfall process can reach 245-980 g without setting the diversion component 500, the deviation can be basically reduced within 1-2 days after the rainfall is finished, and the deviation of setting the diversion component 500 is only 49-122.5 g.
