Description

Technical Field

[0001] The utility model relates to the field of forest litter collection, in particular to a device for collecting artificial forest litter. Background Art

[0002] Forest litter, also known as litter, refers to dead and decomposed plant branches and leaves scattered on the ground surface. Litter is the main way of nutrient return in forest ecosystems. Litter collectors are important tools for collecting plant litter and studying the cycle of plant matter.

[0003] Currently, most of the existing litter collectors are square frame structures with nets placed on the ground. This device has the following main defects: first, it is necessary to find a relatively flat area with moderate soil hardness for placement, which takes a lot of time for preliminary preparation; second, for artificial tree forests planted together (such as poplar plantations), the collection of forest litter is greatly affected by wind force. The litter collector placed on the ground is too far away from the tree crown, and the litter collected by the litter collector is difficult to reflect the actual situation of the forest; third, since the device is placed on the ground, it is easy to collect impurities from other forests.

[0004] Therefore, there is an urgent need for a new device for collecting litter in artificial forests to provide an effective solution to the defects of the existing technology. Summary of the invention

[0005] The purpose of the utility model is to provide a device for collecting litter in artificial forests to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A device for collecting litter in an artificial forest comprises a trunk fixing ring sleeve, a telescopic rod and a litter collection net frame, wherein the trunk fixing ring sleeve comprises a left half ring and a right half ring, both of which are semicircular arc structures, the left half ring and the right half ring are rotatably connected by an outer hinge, the left half ring and the right half ring are detachably connected at one end away from the hinge, at least one hinge seat is provided on the circumferential outer surface of the left half ring and the right half ring, the hinge joint at the bottom of the telescopic rod is hinged to the hinge joint, the end of the telescopic rod away from the hinge joint is connected to the litter collection net frame, the base of the telescopic rod is provided with a rope ring, and a limiting rope is commonly passed through the rope rings on all the telescopic rods.

[0008] Furthermore, a transversely arranged plug plate is provided on the outer side wall of the left half ring at one end away from the hinge, and a transversely arranged plug plate seat is provided on the outer side wall of the right half ring at one end away from the hinge. The plug plate is plugged into the plug plate seat, and both the plug plate and the plug plate seat are provided with plug holes. After the plug plate and the plug plate seat are aligned with the plug holes, a plug column is plugged in.

[0009] Furthermore, a pressure plate with an arc-shaped plate-like structure is arranged on the inner side of the right half ring, a threaded barrel is arranged on the circumferential outer wall of the right half ring, a locking screw is threaded on the threaded barrel, one end of the locking screw is rotatably connected to the pressure plate, and the other end is fixedly connected to a screw seat.

[0010] Furthermore, anti-slip protrusions are provided on the circumferential inner surfaces of the left half ring and the pressure plate.

[0011] Furthermore, a square frame is connected to the upper port of the litter collection net frame, and the square frame is connected to the end of the telescopic rod through a hanging rope.

[0012] Furthermore, the trunk fixing ring sleeve and the telescopic rod are both made of aluminum alloy.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is fixed on the tree trunk through a trunk fixing ring sleeve, and there is no need to find a flat area with moderately soft and hard soil. It can adapt to various complex terrains and will not collect impurities under other forests. Through the adjustment of the telescopic rod, the litter collection frame can be closer to the tree crown, effectively reducing the impact of wind on the collection effect, and more realistically reflecting the actual litter situation in the forest. The left half ring and the right half ring are connected by hinge rotation, which is convenient for quick installation and disassembly; at the same time, the telescopic and rotation functions of the telescopic rod also increase the flexibility and convenience of the device.

[0015] In the utility model, when the left half ring and the right half ring are rotated and closed by the hinge and fixed on the tree trunk, the plug plate at one end of the left half ring is aligned with the plug plate seat at one end of the right half ring. After alignment, the plug plate and the plug plate seat will naturally correspond. The plug post is inserted into the corresponding plug hole to ensure that the left half ring and the right half ring are tightly connected.

[0016] In the utility model, by rotating the screw seat, the locking screw is driven to rotate and move forward in the threaded barrel, thereby pushing the pressing plate to be close to the tree trunk, thereby achieving the fastening and fixing of the right half ring and ensuring the stability of the device on the tree trunk.

[0017] In the utility model, the anti-skid protrusions can increase the friction between the left half ring 2 and the pressing plate 6 and the surface of the tree trunk, thereby improving the fixing effect of the tree trunk fixing ring sleeve 1. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figures 1 to 5 A device for collecting litter in an artificial forest comprises a trunk fixing ring sleeve 1, a telescopic rod 15 and a litter collecting net frame 20. The trunk fixing ring sleeve 1 comprises a left half ring 2 and a right half ring 4, both of which are semicircular arc structures. The left half ring 2 and the right half ring 4 are rotatably connected by an outer hinge 3. The left half ring 2 and the right half ring 4 are detachably connected at one end away from the hinge 3. One or more hinge seats 13 are provided on the circumferential outer surfaces of the left half ring 2 and the right half ring 4. A hinge head 14 at the bottom of the telescopic rod 15 is hinged to the hinge head 13. The end of the telescopic rod 15 away from the hinge head 14 is connected to the litter collecting net frame 20. A rope ring 16 is provided at the base of the telescopic rod 15. A limiting rope 17 is commonly passed through the rope rings 16 on all the telescopic rods 15.

[0026] Working principle of this embodiment:

[0027] Install the trunk fixing ring: First, rotate the left half ring 2 and the right half ring 4 through the outer hinge 3 to form a complete ring structure. Then, detachably connect the left half ring 2 and the right half ring 4 away from the hinge 3, such as using bolts, buckles, etc., to ensure that the ring is tightly fixed on the trunk.

[0028] Install the telescopic rod: On the outer circumferential surface of the left half ring 2 and the right half ring 4, there is a hinge seat 13. The hinge head 14 at the bottom of the telescopic rod 15 is hinged to the hinge seat 13, so that the telescopic rod 15 can rotate and extend at a certain angle around the trunk.

[0029] Connecting the litter collection net frame: The end of the telescopic rod 15 away from the hinge 14 is connected to the litter collection net frame 20. The litter collection net frame 20 is used to capture the litter dropped by the trees. According to conventional scientific research needs, the litter collection net frame 20 is set to a size of 1M*1M.

[0030] Use of limiting rope: A rope ring 16 is provided at the base of the telescopic rod 15, and a limiting rope 17 is passed through the rope rings 16 on all telescopic rods 15. By adjusting the circumference of the limiting rope 17, the opening angle of the telescopic rod 15 can be adjusted, so that the litter collection net frame 20 at the end of the telescopic rod 15 can be used to collect litter from the tree it is installed on, and can also be used to collect litter from neighboring trees. According to the existing spacing between plantations, the maximum extension length of three of the telescopic rods 15 can be set to 1.5 meters for collecting litter from the tree itself; the maximum extension length of one of the telescopic rods 15 can be set to 3 meters for collecting litter from neighboring trees.

[0031] This embodiment is fixed on the tree trunk by the trunk fixing ring sleeve 1. There is no need to find a flat area with moderately soft and hard soil. It can adapt to various complex terrains and will not collect impurities from other forests. By adjusting the telescopic rod 15, the litter collection frame 20 can be brought closer to the tree crown, effectively reducing the impact of wind on the collection effect and more realistically reflecting the actual litter situation in the forest. The left half ring 2 and the right half ring 4 are rotatably connected by the hinge 3, which is convenient for quick installation and disassembly; at the same time, the telescopic and rotation functions of the telescopic rod 15 also increase the flexibility and convenience of the device. This embodiment has a simple and durable structure and can be reused in different artificial forests, reducing the cost of use.

[0032] Example 2: Please refer to Figures 4-5 , a device for collecting litter in artificial forests, which differs from Example 1 in that a transversely arranged plug board 10 is provided on the outer side wall of the left half ring 2 at one end away from the hinge 3, and a transversely arranged plug board seat 11 is provided on the outer side wall of the right half ring 4 at one end away from the hinge 3, the plug board 10 is plugged into the plug board seat 11, and both the plug board 10 and the plug board seat 11 are provided with plug holes, and the plug board 10 and the plug board seat 11 are aligned with the plug holes and then plugged with a plug column 12.

[0033] In this embodiment, when the left half ring 2 and the right half ring 4 are rotated closed and fixed on the tree trunk through the hinge 3, the plug plate 10 at one end of the left half ring 2 is aligned with the plug plate seat 11 at one end of the right half ring 4. After alignment, the plug holes on the plug plate 10 and the plug plate seat 11 will naturally correspond. The plug post 12 is inserted into the corresponding plug hole to ensure that the left half ring 2 and the right half ring 4 are tightly connected and fixed on the tree trunk, thereby improving the stability and collection efficiency of the device.

[0034] Example 3: Please refer to Figures 4-5 , a device for collecting litter in artificial forests, which differs from Example 1 in that a pressing plate 6 with an arc-shaped plate structure is arranged on the inner side of the right half ring 4, a threaded barrel 7 is arranged on the circumferential outer wall of the right half ring 4, and a locking screw 8 is threaded on the threaded barrel 7, one end of the locking screw 8 is rotatably connected to the pressing plate 6, and the other end is fixedly connected to a screw seat 9.

[0035] In this embodiment, by rotating the screw seat 9, the locking screw 8 is driven to rotate and move forward in the threaded tube 7, thereby pushing the pressure plate 6 to fit tightly against the tree trunk, thereby fastening and fixing the right half ring 4 and ensuring the stability of the device on the tree trunk.

[0036] Example 4: Please refer to Figures 4-5 , a device for collecting litter in artificial forests, which differs from Example 3 in that anti-slip protrusions 5 are provided on the circumferential inner surfaces of the left half ring 2 and the pressing plate 6.

[0037] In this embodiment, the anti-slip protrusions 5 can increase the friction between the left half ring 2 and the pressure plate 6 and the surface of the tree trunk, thereby improving the fixing effect of the tree trunk fixing ring sleeve 1.
