Description

Technical Field

[0001] The invention relates to the field of forest ecological technology, and in particular to a forest litter collection device and a collection method thereof. Background Art

[0002] In forest ecosystems, litter, as an important component of the carbon cycle, plays a vital role in accurately estimating forest carbon storage. Litter covers a variety of forms, including but not limited to leaves, bud scales, branches, fruits, and bark with loose cracking characteristics, all of which come from trees of different stand species and ages. In order to comprehensively and accurately assess the carbon storage capacity of forests, these litter samples must be systematically collected.

[0003] However, the complexity of the forest environment poses a huge challenge to the effective collection of litter. In particular, in areas with steep slopes (usually greater than 15°), dense understory vegetation, scattered rocks, and changeable climatic conditions, traditional collection methods often seem to be inadequate. Currently, although there are some patented technologies involving litter collection, such as the use of box-type or metal barrel collection devices, most of these solutions fail to fully consider the actual needs under complex site conditions, especially when dealing with different forest ages, large differences in crown radius, and variable shapes of trunk bases, their applicability and efficiency are insufficient.

DETAILED DESCRIPTION

[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0025] As described in the background technology, the complexity of the forest environment poses a huge challenge to the effective collection of litter. In particular, in areas with steep slopes (usually greater than 15°), dense understory vegetation, scattered rocks, and changeable climatic conditions, traditional collection methods often seem to be inadequate. At present, although there are some patented technologies involving the collection of litter, such as the use of box-type or metal barrel collection devices, most of these solutions fail to fully consider the actual needs under complex site conditions, especially when dealing with different forest ages, large differences in crown radius, and variable shapes of trunk bases, their applicability and efficiency are obviously insufficient.

[0026] Embodiment 1: Therefore, in order to solve the above technical problems in the prior art, this embodiment provides a forest litter collection device, such as Figure 1 , 2 As shown, the collecting device comprises: An adjustable inner ring 400, which is sleeved on the outer side of the tree trunk; A telescopic extension rod 300, wherein a plurality of the telescopic extension rods are provided, and the plurality of the telescopic extension rods are arranged around the tree trunk, and one end of the telescopic extension rod is connected to an adjustable inner ring 400, and the length of the telescopic extension rod can be changed by stretching or squeezing the telescopic extension rod, and a telescopic movable device 500 is provided below the telescopic extension rod 300, and the telescopic extension rod is supported by the telescopic movable device, and the height of the telescopic movable device is adjustable; Extension rods 800, wherein at least one group of extension rods is provided, wherein one group of extension rods is connected to a telescopic extension rod, and the other groups of extension rods are connected end to end, and a telescopic device 600 is provided below the extension rods to support the extension rods, and the telescopic device is height-adjustable; The collecting net 900 is laid on the telescopic extension rod and the extension rod respectively, and is kept fixed to the telescopic extension rod or the extension rod. A sealing net 1100 is also laid between adjacent collecting nets.

[0027] When implementing this embodiment, the grass and bushes on the bottom surface of the forest are first cleared and cut, and an adjustable inner ring device is installed around the bottom of the trunk of the tree 100. According to the size of the crown area, the number of telescopic extension rods to be installed is calculated, such as Figure 3 As shown, with the tree trunk as the center, the retractable extension rods are fixed one by one on the inner ring device, and then the retractable moving device is installed on each retractable extension rod, and the collection net is fixed starting from the first retractable extension rod, with the tree trunk as the center, the dense nets are laid and fixed one by one until the first retractable extension rod is covered again. After fixing, the dense net is cut, and the dense net finally laid is in a circular ring shape to form the first layer of collection net ring. According to the radius of the drip line 200 from the tree trunk, the number of extension rods that need to be added is calculated to obtain the calculation result of the number of extension rods. The calculation method is as follows: ; in, R is the radius of the drip line from the tree trunk, in units of m ; n To increase the number of extension rods, n Get the smallest positive integer; L 1 is the length of the extension rod, in units of m ; L 2 is the length of the extension rod, in units of m ; A It is the connection gap between the extension rod and the telescopic extension rod or the adjacent extension rod, in units of m ; After calculating the number of extension rods, first connect the extension rod to the retractable extension rod, lay the second layer of collection net, and lay the sealing net on the adjacent collection net, and then fix the retractable device on the extension rod; then connect another extension rod, and repeat the above process until all extension rods that meet the preset number are installed. The preset number is the number of extension rods that need to be added as calculated.

[0028] This embodiment adopts a design of a retractable movable device that can be retracted up and down around the trees to adapt to different terrain slopes, especially mountainous areas with slopes greater than 15°, and a retractable device that can be retracted up and down is designed at the bottom of each extension rod, which can adapt to various surface conditions under the forest, making the collection device more stable. At the same time, according to the circumference of the bottom of the standing tree, the device can adjust the number of retractable extension rods to meet the needs of collecting litter from standing trees with different breast diameters; by continuously increasing the number of extension rods, the vertical projection range of the circular edge surrounded needs to completely include the range of the drip line and exceed the periphery of the drip line. The laid collection net adopts the method of laying out ring by ring, and the upper layer at the joint of the rings is covered with a strip of dense net. The edges of the dense net on both sides are fixed with the lower dense net using tie bands to make up for the gaps between the rings and prevent the litter from leaking out of the gaps, thereby causing litter to be missed, resulting in inaccurate research results.

[0029] Embodiment 2: This embodiment provides one structure of an adjustable inner ring, such as Figure 5 As shown, the adjustable inner ring includes a flexible belt 410 and an adjustable buckle 420. The adjustable buckle is fixedly connected to one end of the flexible belt, and the other end of the flexible belt passes through the adjustable buckle to form a flexible belt loop.

[0031] like Figure 8 As shown in the figure, by wrapping the flexible belt around the tree trunk, one end of the flexible belt is inserted into the first insertion hole and passes through the first insertion hole. Without rotating the toggle part, since one side of the spring tongue is in an arc shape and the other side is in a plane perpendicular to the surface of the flexible belt, when the belt is turned Figure 8When the flexible belt moves in the reverse direction, the plane side of the spring tongue perpendicular to the other flexible belt surface will block the saw teeth and prevent the flexible belt from moving. Only by rotating the toggle part to drive the spring tongue to rotate and make it rotate out of the sawtooth part, can the flexible belt move in the reverse direction, thereby realizing the adjustment of the size of the flexible belt ring. By adopting an adjustable length and an inner ring design that is close to the bark, the device can adapt to the bottom shape of the tree trunk that is not all ideally round.

[0032] Of course, this embodiment only provides one structure of the adjustable inner ring, and the adjustable inner ring in the present invention is not limited to the structure described in this embodiment, and other structures may also be used, for example, an elastic band, by wrapping the elastic band around the trunk and then tying it up; or a structure similar to a belt in the prior art.
