Description

Technical Field

[0001] The invention belongs to the technical field of tree transplanting protection devices, in particular to a tree transplanting protection device for forestry engineering. Background Art

[0002] Forestry engineering refers to the application of various engineering technologies to the cultivation, development and utilization of forest resources and processing of forest products based on the principles of efficient use and sustainable development of forest resources. Forestry engineering includes forest area planning, forest cultivation, forest protection and equipment. In forestry engineering, trees are often transplanted and planted. The transplanted trees are supported by protective devices during the growth stage to avoid bending and breaking of the trunks.

[0003] A Chinese patent with application number 201922253933.2 discloses a transplanting tree protection device for forestry engineering. The patent uses the elastic force of a spring to drive an arc-shaped positioning plate to effectively clamp the tree, and can always clamp the tree according to the growth condition of the tree. However, the above positioning plate only clamps the tree by the elasticity of the spring, and the clamping instability is prone to occur in the later stage, resulting in the tree being prone to bending, tilting, etc. during the growth process, reducing the protection effect of the protection device on the tree. In addition, the tree is generally supported by a support frame. Since the support frame directly supports and protects the tree with rigid clamping, the protection device needs to be removed in time when the tree grows tough in the later stage. If the protection device is not removed in time, it is easy to wrap the tree, which is not convenient for the natural growth of the tree. As the trunk thickens, the components on the protection device will also be embedded in the trunk, hindering the transportation of water and nutrients in the seedling body, resulting in the problem of slow growth of the tree. For this reason, we propose a forestry engineering tree transplanting protection device. Summary of the invention

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The transmission assembly includes two groups of threaded rotating columns 121 and two groups of rotating rods 110. A large outer gear ring 117 is sleeved and fixed on the outside of the threaded rotating column 121. A small outer gear rod 116 is meshed on the outside of the large outer gear ring 117. A lower oblique bevel gear 122 is sleeved and fixed on the outer side of the end of the small outer gear rod 116. An upper oblique bevel gear 123 is fixedly sleeved on the bottom of the rotating rod 110. The lower oblique bevel gear 122 meshes with the upper oblique bevel gear 123. An L-shaped plate 115 is fixedly provided on the top of the left frame 103 and the right frame 111. The ends of the small external gear rod 116 and the threaded rotating column 121 pass through the interior of the L-shaped plate 115. The small external gear rod 116 is rotationally connected to the L-shaped plate 115, and the threaded rotating column 121 is rotationally connected to the L-shaped plate 115 through a thread. The threaded rotating column 121 moves toward or away from the trunk when rotating. A limit strip 118 is slidingly provided inside the L-shaped plate 115. The end of the limit strip 118 is fixedly connected to the outer wall of the clamping member 104, so that the clamping member 104 can be limited when it moves. A support bearing 124 is embedded in the interior of the L-shaped plate 115. The bottom of the rotating rod 110 passes through the interior of the support bearing 124. An upper bearing 125 is fixedly sleeved on the outer side of the top of the rotating rod 110. The upper bearing 125 is inserted through the inner The outer ring 128 can be composed of a ring and an outer ring, and the mounting ring 128 is fixed to the bottom of the outer ring. The outer sleeve of the upper bearing 125 is fixed with a tooth column 109, and the bottom of the upper bearing 125 is fixed with a mounting ring 128. After the locking screw 126 and the mounting ring 128 are fixed together, when the tooth column 109 rotates, the outer ring on the upper bearing 125 will be driven to rotate, and the outer ring can drive the bottom mounting ring 128, the locking screw 126, the vertical plate 127, the fixed plate 129 and the rotating rod 110 to rotate. By separating the working end of the locking screw 126 from the mounting ring 128 and no longer contacting each other, when the tooth column 109 rotates, the rotating rod 110 will not be driven to rotate under the action of the upper bearing 125, so that when the arc plate 108 or the clamping member 104 is moved separately during the installation process of the left frame 103 and the right frame 111, they will not rotate with each other; A fixing plate 129 is also sleeved and fixed on the outside of the rotating rod 110, and two sets of vertical plates 127 are fixedly arranged on the top of the fixing plate 129. The interior of the vertical plates 127 is connected with a locking screw 126 through a thread, and the working end of the locking screw 126 extends to the outer wall of the mounting ring 128; The outside of the tooth column 109 is meshed with a tooth plate 106, and the top of the left frame 103 and the right frame 111 are fixedly provided with an L-shaped frame 114, the top of the L-shaped frame 114 is fixedly provided with a fixed rail 113, and the inside of the fixed rail 113 is slidably provided with a slide rail 119. When the tooth plate 106 moves, it will drive the slide rail 119 to slide on the fixed rail 113, and the slide rail 119 is fixed to the back of the tooth plate 106.

[0022] Embodiment 2 Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8The clamping assembly includes two groups of clamping members 104. The clamping member 104 includes an arc-shaped clamping plate and a buffer plate. The buffer plate is fixed to the inner wall of the arc-shaped clamping plate. A vertical bearing 120 is provided at the end of the threaded rotating column 121. Through the vertical bearing 120, the threaded rotating column 121 can prevent the clamping member 104 from rotating during rotation. The vertical bearing 120 is fixed to the outer wall of the clamping member 104.

[0023] The tightening component includes an arc plate 108, and a rubber plate 107 is fixedly provided on the inner wall of the arc plate 108. The rubber plate 107 can have a buffering effect to reduce the impact of the arc plate 108 directly contacting the outer wall of the trunk on its surface. The arc plate 108 is fixed to the end of the tooth plate 106.

[0024] The adaptive protection mechanism designed in the present invention can not only clamp, fix and support trees during use, but also can squeeze the trunk and move outward as the trunk thickens during the growth of the tree, thereby driving the clamping member 104 to automatically move outward, so that the clamping member 104 can adaptively clamp and support the thickened trunk according to the growth of the tree, and can also effectively clamp, support and protect the trunk, thereby avoiding the situation where the protective device is not removed in time at a later stage, affecting the natural growth of the tree, and improving the supporting and protecting effect of the protective device on the tree.

[0025] During use, first loosen the locking screw 126 by turning it outward, and then the working end of the locking screw 126 will be separated from the surface of the mounting ring 128. Then, the left frame 103 and the right frame 111 are placed at appropriate positions on the tree trunk, and the bottom of the insertion rod 100 is inserted into the ground. Then, the left frame 103 and the right frame 111 are locked and fixed using the mounting bolts. Then, both sets of clamping members 104 are moved toward the direction of the tree trunk, and then the inner wall of the buffer plate on the clamping member 104 contacts the outer wall of the tree trunk and clamps the tree trunk. Then, the two sets of arc plates 108 are moved toward the direction close to the tree trunk and contact the outer wall of the tree trunk. Then, the locking screw 126 is rotated toward the direction close to the mounting ring 128, and then the working end of the locking screw 126 contacts and is fixed to the mounting ring 128. At this time, the tree can be supported and protected. When the tree grows strong enough, if the protective device is not removed in time, the tree will grow thicker and the curved plate 108 will be squeezed away from the trunk. The curved plate 108 will move outward, driving the tooth plate 106 to move away from the trunk, and then driving the tooth column 109 to rotate. The tooth column 109 drives the upper bearing 125 to rotate. Since the bottom of the upper bearing 125 is fixedly connected to the locking screw 126 through the mounting ring 128, the locking screw 126 is fixed between the vertical plate 127, the fixing plate 129 and the rotating rod 110. Under the action of the fixed, the upper bearing 125 can drive the rotating rod 110 to rotate when it rotates, and the rotating rod 110 drives the upper inclined bevel gear 123 to rotate, and then drives the small outer gear rod 116 to rotate under the meshing condition of the upper inclined bevel gear 123 and the lower inclined bevel gear 122, and drives the large outer gear ring 117 and the threaded rotating column 121 to rotate. At this time, the threaded rotating column 121 rotates and moves away from the trunk, driving the clamping member 104 to move, and then the buffer plate in the clamping member 104 begins to move outward, reducing the impact of the clamping member 104 on the trunk.

[0026] Embodiment 3 Based on Example 2, please refer to Figure 1 , Figure 2 and Fig. 9 A lifting assembly is provided on one side of the left frame 103 and the right frame 111. The lifting assembly includes two sets of fixed blocks 200 fixed on one side of the left frame 103 and the right frame 111. A moving rod 201 is provided inside the fixed block 200. The top of the cylinder 102 is fixedly connected to the bottom of the moving rod 201. The interior of the fixed block 200 is connected with a threaded rod 204 through a thread, and the threaded rod 204 can lock and fix the fixed block 200 and the movable rod 201. The outer sleeve of the threaded rod 204 is fixed with an outer ring 203, and the outer sleeve of the outer ring 203 is provided with a transmission belt 202. The transmission belt 202 can drive the other set of threaded rods 204 to rotate when one set of threaded rods 204 is rotated, saving time and physical effort.

[0027] The lifting assembly designed in the present invention can not only adjust the height of the protective device according to the terrain or the height of the tree during the process of installing the protective device on the tree trunk, but also can be lifted and lowered to continue clamping and supporting other positions of the tree trunk after the inner wall of the buffer plate on the clamping member 104 has been in contact with the tree trunk for a long time, thereby avoiding the inner wall of the buffer plate from being in contact with the fixed position of the tree trunk for a long time, resulting in wear and poor nutrient delivery at the contact part of the trunk and the buffer plate, thereby further improving the protection effect on the tree.

[0028] When the left frame 103 and the right frame 111 are installed, the position of the clamping member 104 can be adjusted according to the height of the tree or the need at a later time, and the clamping member 104 can be raised or lowered as needed. When lifting or lowering, the threaded rod 204 located on one side of the left frame 103 and the right frame 111 is held, and the threaded rod 204 rotates outward, and then the working end of the threaded rod 204 is separated from the surface of the moving rod 201. When the threaded rod 204 rotates, the other set of threaded rods 204 are driven to rotate by the driving action of the transmission belt 202, and then the arc plate 108 is moved outward, driving the clamping member 104 to move so that the inner wall of the clamping member 104 is no longer in contact with the tree trunk. , and then move the left frame 103 and the right frame 111 upward or downward, driving the arc plate 108, the clamping member 104 and other structures to move with them, and stop moving after moving to a suitable height position. At this time, the arc plate 108 is moved toward the direction close to the trunk and contacts the trunk, thereby driving the clamping member 104 below to move toward the trunk and clamp the trunk, completing the clamping support protection of the trunk or allowing the clamping member 104 to replace different positions of the trunk for clamping support protection, thereby avoiding the inner wall of the buffer plate from contacting with the fixed position of the trunk for a long time, resulting in wear and poor nutrient delivery at the contact part of the trunk and the buffer plate.

[0029] Embodiment 4 Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The arc-shaped splint includes a main board 305 and two groups of sub-boards 301. The main board 305 and the sub-boards 301 are rotatably connected via a rotating shaft. The buffer plate includes a main buffer rubber 303 and two groups of sub-buffer rubbers 300. The main buffer rubber 303 and the sub-buffer rubber 300 are in contact with the outer wall of the trunk, which can play a buffering effect and reduce the impact on the trunk. The main buffer rubber 303 and the sub-buffer rubber 300 are respectively fixed on the inner walls of the main board 305 and the sub-board 301.

[0030] The top and bottom of the main board 305 are fixed with a fixing frame 302, and the top and bottom of the sub-board 301 are fixed with a stud 306. The stud 306 can rotate with the rotation of the sub-board 301. The end of the stud 306 passes through the interior of the fixing frame 302, and the outside of the stud 306 is connected with a screw ring 307 through a thread.

[0031] The present invention combines the designed fixing frame 302, stud 306, screw ring 307, rotating shaft, etc. When the clamping member 104 is clamping and supporting the tree trunk, the angle between the sub-plate 301 and the main plate 305 can be adjusted according to the diameter of the trunk, so that the clamping member 104 can better fit the diameter of the trunk when clamping, thereby improving the applicability of the protective device.

[0032] When the clamping member 104 is in use and clamps the trunk for support and protection, if the diameter of the trunk is not compatible with the diameter of the clamping member 104, the opening size of the clamping member 104 can be adjusted. When adjusting, the screw ring 307 is turned away from the sub-plate 301 and unscrewed. Then the sub-plate 301 is rotated outward or inward around the rotating shaft between the sub-plate 301 and the main plate 305 to a suitable angle. The sub-plate 301 will drive the sub-buffer rubber 300 to follow the rotation angle. After adjustment, the screw ring 307 is turned toward the sub-plate 301 and locked to fix the sub-plate 301, so that the inner wall of the sub-buffer rubber 300 and the inner wall of the main buffer rubber 303 can be tightly attached to the outer wall of the trunk, thereby making the inner wall of the buffer plate in the clamping member 104 fit the outer wall of the trunk more closely.

[0033] In this embodiment, the left frame 103 and the right frame 111 are fixedly connected by installing bolts, and the left frame 103 and the right frame 111 can be assembled and disassembled by disassembling the mounting bolts. A first connecting bar 101 is fixedly arranged between the two groups of cylinders 102, and a second connecting bar 112 is arranged between the two groups of first connecting bars 101, and both ends of the second connecting bar 112 are fixedly connected to the first connecting bar 101 by fixing bolts. The second connecting bar 112 and the first connecting bar 101 can be assembled and disassembled by fixing bolts. After the left frame 103 and the right frame 111 are fixed, the two ends of the second connecting bar 112 are fixed to the first connecting bar 101 by fixing bolts to increase stability. An insertion rod 100 is fixedly arranged inside the cylinder 102.

[0034] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
