Description

Technical Field

[0001] This utility model relates to the technical field of forest litter collection devices, and in particular to a device for the complete harvesting of litter from a single tree. Background Technology

[0002] A litter collection device is a specialized device used to collect components such as branches, leaves, and bark that have fallen from trees. These litter materials are generally considered an important component of forest ecosystems, providing nutrients and energy and playing a vital role in the health and stability of the ecosystem. Therefore, research on forest litter is essential. To better understand the dynamic changes in forest litter, long-term research periods are needed to calculate the changing trends of various litter components over time. In this way, a deeper understanding of the evolutionary patterns of litter in forest ecosystems can be achieved, providing a scientific basis for ecosystem protection and management.

[0003] Chinese utility model patent CN205352742U discloses a forest shrub litter collection device, which includes a collection net. The collection net is an inverted frustum-shaped net with an upper diameter of 1.13m, a lower diameter of 0.5m, and a height of 20cm. It is a nylon mesh collection bag with 1mm mesh openings on the side and a retractable drawstring at the bottom for securing the collection net to the shrub head. In other words, the litter is removed from the collection net by fitting it to the shrub's diameter with the drawstring and opening on the side. This method requires workers on site a considerable amount of time to remove the litter from each collection net.

[0004] Chinese utility model patent CN208399174U discloses a debris collection funnel. Similarly, to facilitate debris collection, a nut is installed at the bottom of the funnel. This method of clearing debris from the bottom of the funnel also results in workers needing a longer time to remove the debris, leading to low on-site work efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a device for the complete harvesting of litter from a single tree, which enables workers to collect litter quickly on site and improves the efficiency of on-site operations.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A device for harvesting all litter from individual trees includes a circular frame, two telescopic rods, two collection nets, at least three support rods, and a bent tee connector.

[0008] The circular frame includes at least four arc rods, which are spliced ​​together to form a circle, and adjacent arc rods are connected by the elbow tee connector.

[0009] The two telescopic rods are arranged along the same diameter of the circular frame, with one end of the telescopic rod connected to the circular frame via the elbow tee connector, and the other end extending to the tree trunk;

[0010] One of the collection nets is placed between the two telescopic rods and half of the circular frame located on one side of the two telescopic rods, and the other collection net is placed between the two telescopic rods and half of the circular frame located on the other side of the two telescopic rods.

[0011] On the circular frame, at least three of the elbow tee joints are connected to the support rod below, and the lower end of the support rod is fixed in the soil.

[0012] Furthermore, it also includes an adjustable ring, which is a variable diameter flexible tube with one end having a smaller diameter than the other end. One end of the adjustable ring extends into the inner hole of the other end. The adjustable ring is arranged around the tree trunk, and the other end of the telescopic rod is connected to the adjustable ring through the elbow tee connector.

[0013] Furthermore, it also includes a rubber filler, which is disposed within the adjustable ring or between the adjustable ring and the trunk.

[0014] Furthermore, it also includes hooks, of which there are multiple hooks, and multiple hooks are evenly distributed on the circular frame and the telescopic rod, with the upper end of the collection net hanging on the hooks.

[0015] Furthermore, the collecting net is circular, and a tightening rope is provided at the upper end of the collecting net.

[0016] Furthermore, it also includes a locking knob, and the telescopic rod includes a thin rod and a thick rod that slides on the thin rod, and the thin rod and the thick rod are locked and fixed together by the locking knob.

[0034] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] Please refer to Figures 1 to 8 The embodiments provided by this utility model are as follows:

[0036] A device for the complete harvesting of litter from individual trees, such as Figure 1 As shown, the device includes a circular frame 1, two telescopic rods 2, two collection nets 3, at least three support rods 4, and elbow tee connectors 5. The circular frame 1 includes at least four arc rods 11, which are spliced ​​together to form a circle. Adjacent arc rods 11 are connected by elbow tee connectors 5. The spliced ​​circular frame 1 facilitates the transportation of the device.

[0037] The elbow tee connector 5 includes two arc-shaped pipe sections and one straight pipe section, such as... Figure 6 As shown, two arc-shaped tube segments are used to connect arc-shaped rods, such as arc rod 11, and straight tube segments are used to connect straight rods, such as support rod 4.

[0038] Furthermore, the two telescopic rods 2 are arranged along the same diameter of the circular frame 1. One end of the telescopic rod 2 is connected to the circular frame 1 through the elbow tee connector 5, and the other end extends to the tree trunk. The tree trunk is located at the center of the device, and the two telescopic rods 2 are located on the left and right sides of the tree trunk, respectively. One end of the two telescopic rods 2 is connected to the circular frame 1. In this way, the area between the circular frame 1 and the tree trunk is divided into two semi-circular areas by the two telescopic rods 2.

[0039] Next, one collection net 3 is placed between the two telescopic poles 2 and half of the circular frame 1 located on one side of the two telescopic poles 2, and the other collection net 3 is placed between the two telescopic poles 2 and half of the circular frame 1 located on the other side of the two telescopic poles 2. That is, two collection nets 3 are used to collect the fallen debris in the two semi-circular areas divided by the two telescopic poles 2, thus enabling the two collection nets 3 to collect all the fallen debris around the tree trunk. During on-site operations, workers remove the collection nets 3 from the circular frame 1 and the two telescopic poles 2, and then take away the collection nets 3 and the fallen debris contained within them. Then, two empty collection nets 3 are installed on the circular frame 1 and the two telescopic poles 2 to continue collecting the next stage of fallen debris. The entire process of replacing the collection nets 3 can be completed within 2-5 minutes, greatly shortening the workers' on-site operation time.

[0040] To support the circular frame 1, at least three elbow tee joints 5 are connected to the support rods 4 below the circular frame 1. The lower ends of the support rods 4 are fixed in the soil to fix the device and provide force support for the collection net 3.

[0041] Furthermore, it also includes an adjustable ring 6, such as Figure 5 As shown, the adjustable ring 6 is a variable-diameter flexible tube with one end smaller than the other. One end of the adjustable ring 6 extends into the inner hole of the other end. The adjustable ring 6 is arranged around the tree trunk, and the other end of the telescopic rod 2 is connected to the adjustable ring 6 through the elbow tee connector 5. The adjustable ring 6 contacts the tree trunk, and the use of a flexible tube avoids affecting the growth of the tree trunk. The adjustable ring 6 extends into two arc-shaped sections of the elbow tee connector 5, and the other end of the telescopic rod 2 extends into one straight section of the elbow tee connector 5, thus connecting the adjustable ring 6 and the telescopic rod 2. Here, the adjustable ring 6 does not provide support for the telescopic rod 2; it is positioned between the telescopic rod 2 and the tree trunk primarily to prevent litter from falling between the tree trunk and the collection net 3, thereby further improving the ability to collect all litter.

[0042] Furthermore, in order to further prevent the adjustable ring 6 from damaging the tree trunk and to ensure that all fallen debris falls into the collection net 3, a rubber filler is also included. The rubber filler is placed inside the adjustable ring 6 or between the adjustable ring 6 and the tree trunk.

[0043] Specifically, to facilitate quick connection and removal between the collection net 3, the circular frame 1, and the telescopic rod 2, hooks 7 are also included. Multiple hooks 7 are evenly distributed on the circular frame 1 and the telescopic rod 2, and the upper end of the collection net 3 is hung on one of the hooks 7. The hooks 7 further facilitate quick operation by on-site personnel. Figure 2 As shown, the hook 7 has a through hole at the upper end and an open hook at the lower end.

[0044] Specifically, such as Figure 4 As shown, the collecting net 3 is circular, and a tightening rope 31 is provided at the upper end of the collecting net 3. When the collecting net 3 is removed from the hook 7 of the device, pulling the tightening rope 31 can quickly close the collecting net 3, further reducing the on-site operation time of workers and improving on-site operation efficiency.

[0045] Specifically, it also includes a locking knob 8, and the telescopic rod 2 includes a thin rod 21 and a thick rod 22 that slides on the thin rod 21, such as... Figure 8 As shown, the thin rod 21 and the thick rod 22 are locked together by the locking knob 8. The telescopic rod 2 can accommodate installations on tree trunks of different diameters and facilitates transportation. The locking knob 8 secures the thin rod 21 relative to the thick rod 22 after length adjustment.

[0046] Furthermore, such as Figure 3As shown, the support rod 4 includes a small round rod 41 and a large round rod 42 arranged sequentially from top to bottom. The small round rod 41 slides into the inner hole of the large round rod 42, and the small round rod 41 and the large round rod 42 are locked and fixed together by the locking knob 8. By adjusting the position of the small round rod 41 relative to the large round rod 42, the device can be adapted to installation at different heights and to meet the needs of different ground heights. The locking knob 8 is used to lock and fix the small round rod 41 relative to the large round rod 42.

[0047] Furthermore, it also includes a straight-through tee connector 9, such as... Figure 7 As shown, the straight-through tee connector 9 includes three straight pipe sections connected together. As shown in the figure, the central axes of two of the straight pipe sections are on a straight line. In use, each telescopic rod 2 extends into the two straight pipe sections with their central axes on a straight line, and the upper end of the support rod 4 extends into the remaining straight pipe section. That is, the upper end of the telescopic rod 2 is connected to the support rod 4 through one straight-through tee connector 9. The lower end of the support rod 4 is fixed in the soil. The support rod 4 further supports the telescopic rod 2, improving the structural stability of the device.

[0048] The installation method of the above-mentioned device for harvesting all litter from individual trees is as follows:

[0049] Step 1: Assemble the arc rod 11 and the elbow tee connector 5 to form a circular frame 1. Then, fix at least three support rods 4 below the circular frame 1 through the assembled elbow tee connector 5. The support rods 4 are fixed in the soil below.

[0050] Step 2: Connect one end of each telescopic rod 2 to the two elbow tee connectors 5 on opposite sides of the pre-assembled circular frame 1. Extend the other end of the telescopic rod 2 toward the tree trunk and surround the tree trunk with an adjustable ring 6. Connect the adjustable ring 6 to the other end of the telescopic rod 2 through the elbow tee connectors 5. Add rubber filler between the tree trunk and the adjustable ring 6, or inside the adjustable ring 6. After adjusting the position and length of the adjustable ring 6, use the locking knob 8 to lock and fix the two ends of the adjustable ring 6. After adjusting the position and length of the telescopic rod 2, use the locking knob 8 to lock and fix the thick rod 22 and the thin rod 21 of the telescopic rod 2.

[0051] Step 3: In the installation of Step 2, at least one straight-through tee connector 9 is fitted onto one telescopic rod 2. In this step, the support rod 4 is installed through the pre-laid straight-through tee connector 9, and the lower end of the support rod 4 is fixed in the soil.

[0052] Step 4: Using the hooks 7 on the circular frame 1 and the telescopic rod 2, place one collection net 3 between the two telescopic rods 2 and half of the circular frame 1 located on one side of the two telescopic rods 2, and place another collection net 3 between the two telescopic rods 2 and half of the circular frame 1 located on the other side of the two telescopic rods 2. In this step, since the length of the circular frame 1 and the telescopic rod 2 is greater than a person's arm, a person can walk under the circular frame 1 and the telescopic rod 2 to install the collection net 3.

[0053] During use, the two telescopic rods 2 divide the circular area containing the circular frame 1 into two semi-circular areas. One collection net 3 collects the debris between the half-circular frame 1 area and the two telescopic rods 2, while the other collection net 3 collects the debris between the other half-circular frame 1 area and the two telescopic rods 2.

[0054] The above-mentioned device for harvesting all litter from individual trees is operated by workers on-site as follows: the worker enters below the circular frame 1 and the telescopic rod 2, removes the two collection nets 3 from the hooks 7, and uses the tightening rope 31 to close the collection nets 3; the worker then installs the two empty collection nets 3 onto the circular frame 1 and the telescopic rod 2 via the hooks 7.

[0055] The above-mentioned on-site operations are quick and convenient, requiring little time; the replacement of collection net 3 can be completed within 2-5 minutes.

[0056] In summary, the advantages of the device for harvesting all litter from a single tree provided by this utility model are as follows:

[0057] 1. Two telescopic poles 2 are installed in the middle of the circular frame 1 to divide the area where the circular frame 1 is located into two semi-circular areas. Then, two collection nets 3 are used to cleverly collect all the fallen debris under the trees. This application carries out on-site operations by replacing the collection nets 3. Compared with the prior art, the collection nets 3 of this application do not need to have bottom openings, nor do they need to remove fallen debris from under the collection nets 3, which greatly shortens the on-site operation time and improves the efficiency of on-site operations.

[0058] 2. The adjustable ring 6 and rubber filler not only prevent litter from falling between the device and the tree trunk, enabling complete collection of litter, but also prevent the device from damaging the tree trunk.

[0059] 3. The hooks 7 on the circular frame 1 and the telescopic rod 2 facilitate the removal and installation of the collection net 3;

[0060] 4. The adjustable length support rod 4 allows the device to adapt to trees of different heights and ground of varying elevations.

[0061] 5. The device can be adapted to trees of different areas by using an additional number of rings and an adjustable telescopic rod 2.

[0062] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
