Description

Technical Field

[0001] The invention relates to the technical field of gardening equipment, in particular to a tree fixing frame for landscape gardening. Background Art

[0002] In forestry, new trees need to be planted every year. After transplanting, trees need to be reinforced with corresponding support and protection frames to ensure the trees' wind resistance and resistance to falling. The conventional method is to distribute multiple support frames on the outside of the transplanted trees, and then fix the tops of the multiple support frames to the outside of the trees with wire or other means to achieve support and protection for the transplanted trees.

[0003] According to a Chinese patent application with publication number 202411330002.7, a support and protection device for tree transplanting in forestry is disclosed. Through the cooperation of the protective pad, arc-shaped cavity, driving member and fastening nut, the air pressure in the protective pad can be changed by the growth of the tree. The air pressure is used as the power to make the driving member drive the fastening nut to move, thereby achieving the purpose of adjusting the space between the two fixing rings and protecting the tree. However, as the tree grows, it will inevitably carry the fixing ring upward. Therefore, it is necessary to manually adjust the length of the support rod regularly. That is to say, the adaptive effect of the above-mentioned support and protection device for tree transplanting in forestry to the growth of trees is not ideal, and it cannot adapt to the growth of trees and adjust itself. For this reason, we propose a tree fixing frame for landscape gardening to solve the above-mentioned technical problems. Summary of the Invention

[0046] As a preferred solution of the present invention, guardrails are fixedly provided on the periphery of the plurality of fixing units, and the guardrails are used for enclosure and protection of the tree fixing racks of the landscape garden.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] 1. In the present invention, an annular hoop is fixedly installed at an appropriate height on the tree trunk, and the ends of multiple steel cables are fixedly connected to the surface of the annular hoop by locks. Due to the torsion limiting effect of the torsion limiting unit on the vertical shaft, the vertical shaft and the I-shaped pulley cannot rotate. Therefore, the pulling forces of the three steel cables on the tree trunk in multiple directions offset each other, thereby straightening the tree laterally and preventing the tree from falling sideways.

[0049] 2. In the present invention, when the wind direction blows the tree trunk to swing to one side, one of the steel cables corresponding to the wind direction is pulled, causing the steel cable to generate a pulling force on the winding wheel 1, and the pulling force can be decomposed into a component toward the tree and an upward component. At this time, since the angle R1 is large, the upward component of the steel cable tension is small and is not enough to pull the winding wheel 1 upward. At this time, the tree swinging force is offset by the tension of the steel cable to ensure that the tree will not fall sideways.

[0050] 3. In the present invention, as the tree grows taller, the annular hoop will be driven to move upward, causing the angles of R1 and R2 to gradually decrease. At this time, the steel cable is subjected to force and stretched. Since the angle of R1 becomes smaller, the upward component of the steel cable pulling force on the winding wheel 1 becomes larger, causing the winding wheel 1 to move upward, so that the torque limiting unit releases the torque limit on the vertical shaft and the I-spool. The steel cable is subjected to force and stretching, and the I-spool is driven to rotate through the winding action of the winding wheel 1 and the upper and lower winding wheels 2, releasing the remaining steel cable portion wound inside the I-spool, thereby eliminating the stretching of the steel cable.

[0051] 4. In the present invention, after the tensile force on the steel cable disappears, the resilience of the spring is released, pushing the spring bracket, guide rod, bearing seat 1 and winding wheel 1 to reset downward. In addition, the spring bracket also drives the metal pick plate to reset downward, and further drives the torsion limiting disk 1 to move downward through the metal pick plate and insert it into the interior of the circular cavity again. At the same time, due to the setting of the guide bevel 2 and the guide bevel 1, a guiding effect can be achieved, so that the keyway can slide smoothly and be stuck on the periphery of the key tooth. At this time, the torsion limiting disk 2 is limited by the torsion limiting disk 1, resulting in the vertical shaft and the I-shaped wheel being torsion limited, and the steel cable inside the I-shaped wheel is interrupted and released, ensuring that the steel cable will not accumulate between the trunk and the winding wheel 1, so that the steel cable has sufficient tension.

[0052] 5. In the present invention, the rotation of the I-wheel drives the vertical shaft and the gear to rotate. Since the gear is engaged with the rack, the gear rolls along the side of the rack, thereby driving the traveling platform to translate along the sliding track of the linear guide and the linear slider, resulting in the angles R1 and R2 gradually increasing. The increase in the R1 angle reduces the upward component of the force of the steel cable on the winding wheel 1. Therefore, when the tree swings, the winding wheel 1 will not move upward. Therefore, under the engagement of the keyway and the key teeth, the I-wheel cannot rotate. Therefore, the length of the steel cable between the winding wheel 1 and the tree will not change, thereby providing a lateral straightening effect on the tree. The increase in the R2 angle causes the horizontal component of the force of the steel cable on the tree to increase, thereby improving the lateral pulling effect on the tree, that is, improving the lateral fixing effect on the tree.

[0066] See also Figures 1 to 11 The technical solution provided by the present invention specifically includes the following embodiments:

[0067] A tree fixing frame for landscape gardening includes a fixing unit 100, a winding unit 200, a torque limiting unit 300, a traveling unit 400 and a guardrail 500. The fixing units 100 are arranged in a circular array around the periphery of the tree for fixing the tree. The winding unit 200 is fixedly arranged on the top of the fixing unit 100. The torque limiting unit 300 is fixedly arranged on the surface of the winding unit 200 for braking the fixing unit 100. The traveling unit 400 is fixedly arranged on the top of the fixing unit 100 for moving the fixing unit 100. Guardrails 500 are fixedly arranged around the periphery of multiple fixing units 100. The guardrails 500 are used for enclosure and protection of the tree fixing frame for landscape gardening.

[0068] For further details, please refer to Figures 4 to 7 As shown:

[0069] The fixing unit 100 includes a base 101, a traveling platform 102, a vertical shaft 103, an I-shaped pulley 104, a steel cable 105 and an annular hoop 106. The base 101 is fixedly installed on the ground outside the tree through a channel steel beam. The traveling platform 102 is movably arranged on the top of the base 101. A groove 1002 is provided at the end of the traveling platform 102 close to the tree. The vertical shaft 103 is rotatably installed inside the traveling platform 102 through a bearing and passes through the top and bottom of the traveling platform 102. The I-shaped pulley 104 is fixedly installed on the outer wall of the vertical shaft 103 and is located at the top of the traveling platform 102. A gap for installing the torque limiting unit 300 is provided between the bottom of the I-shaped pulley 104 and the top of the traveling platform 102. The steel cable 105 is wrapped around the inside of the I-shaped pulley 104. The annular hoop 106 is fixedly installed on the periphery of the trunk of the tree. The end of the steel cable 105 away from the I-shaped pulley 104 is fixedly connected to the annular hoop 106 by a lock.

[0070] Specifically, at least three bases 101 are fixedly installed on the periphery of the tree trunk through channel steel beams, and the angles between the bases 101 are equal. The channel steel beams can be fixed to the ground through ground nails (but not limited to ground nails), and the annular hoop 106 is fixedly installed at an appropriate height on the tree trunk, and the ends of the multiple steel cables 105 are fixedly connected to the surface of the annular hoop 106 through locks (as shown in the attached figure). Figure 1 As shown in FIG, due to the torsion limiting effect of the torsion limiting unit 300 on the vertical shaft 103, the vertical shaft 103 and the I-shaped pulley 104 cannot rotate. Therefore, the pulling forces of the three steel cables 105 on the tree trunk in multiple directions offset each other, thereby straightening the tree laterally and preventing the tree from falling sideways.

[0071] For further details, please refer to Figures 5 to 8 As shown:

[0072] The winding unit 200 includes a support rod 201, a support platform 202, a linear bearing 203, a guide rod 204, a bearing seat 205, a winding wheel 206, a spring bracket 207, a spring 208, a bearing seat 209 and a winding wheel 2010. The support rods 201 are fixedly installed on the front and rear ends of the top of the walking platform 102 on the left and right sides. The support platform 202 is fixedly installed on the top of the four support rods 201. The linear bearings 203 are fixed symmetrically on the left and right ends of the top of the support platform 202 with the central axis of the support platform 202. There are four of them. The guide rods 204 are slidably installed in the four linear bearings 203 respectively. The bearing seats 205 are fixedly installed on the top of the two guide rods 204 at the front and the top of the two guide rods 204 at the rear. There are two bearing seats 205 in total. The winding wheel 20 6 is rotatably installed between the front and rear two bearing seats 205, the steel cable 105 is wound around the surface of the winding wheel 1 206, the spring bracket 207 is fixedly installed on the bottom of the two guide rods 204 at the front end and the bottom of the two guide rods 204 at the rear end, there are two spring brackets 207, the springs 208 are respectively sleeved on the periphery of the four guide rods 204, and are fixedly installed between the bottom of the support platform 202 and the top of the spring bracket 207, the bearing seat 209 is respectively fixedly installed on the two opposite surfaces of the groove 1002, and the winding wheel 2010 is rotatably installed between the two bearing seats 209 in an upper and lower distribution. After the steel cable 105 is wound around the bottom of the lower winding wheel 2010, it passes through between the upper and lower winding wheels 2010, and is wound around the lower end of the winding wheel 1 206 and fixedly connected to the annular hoop 106.

[0073] Specifically, the annular hoop 106 is fixedly installed at an appropriate height on the tree trunk, and the ends of the plurality of steel cables 105 are fixedly connected to the surface of the annular hoop 106 by means of a lock. At this time, the angle between the steel cables 105 and the vertical surface of the winding wheel 206 is R1, and the angle between the steel cables 105 and the tree trunk is R2 (as shown in the attached figure). Figure 11 As shown in FIG1 ), when the wind blows the tree trunk to swing to one side, one of the steel cables 105 corresponding to the wind direction is pulled, causing the steel cable 105 to generate a pulling force on the winding wheel 206, and the pulling force can be decomposed into a component toward the tree and an upward component. At this time, since the angle R1 is large, the upward component of the pulling force of the steel cable 105 is small and is not enough to pull the winding wheel 206 upward. At this time, the pulling force of the steel cable 105 is used to offset the tree's swinging force, ensuring that the tree will not fall sideways.

[0074] For further details, please refer to Figure 8 、 Figure 9 As shown:

[0075] The torque limiting unit 300 includes a metal pick plate 301, a circular notch 302, a torque limiting disc 1 303, a torque limiting disc 2 304, a keyway 305, a guide slope 1 306, a circular cavity 307, a key tooth 308 and a guide slope 2 309. The metal pick plate 301 is fixedly mounted on the end of the bottom of the two spring brackets 207 away from the tree and is located at the bottom of the I-shaped wheel 104. The circular notch 302 is opened at the end of the top of the metal pick plate 301 away from the spring bracket 207. The torque limiting disc 1 303 is fixedly mounted on the bottom of the metal pick plate 301 and is located outside the opening of the circular notch 302. The torque limiting disc 2 304 is fixedly mounted on the outer wall of the vertical shaft 103. A fitting gap is provided between the outer wall of disk 1 303 and the inner wall of torque limiting disk 2 304, and the fitting gap between the outer wall of torque limiting disk 1 303 and torque limiting disk 2 304 is approximately 1±0.5 mm. Key slots 305 are distributed at equal angles on the lower part of the outer wall of torque limiting disk 1 303, guide slope 1 306 is provided at both ends of the bottom of the inner wall of key slot 305, circular cavity 307 is provided at the top of torque limiting disk 2 304, key teeth 308 are integrally formed and fixed on the inner wall of circular cavity 307, and are distributed in a circular array. The number and specifications of key teeth 308 are compatible with the number and specifications of key slots 305, and guide slope 2 309 is provided at both ends of the top of key teeth 308.

[0076] Specifically, as the tree grows taller, the hoop 106 is driven to move upward, causing the angles R1 and R2 to gradually decrease. At this time, the cable 105 is stretched by force. Since the angle R1 decreases, the upward component of the pulling force of the cable 105 on the reel 1 206 becomes larger, causing the reel 1 206 to move upward. The upward movement of the reel 1 206 drives the guide rod 204 to slide upward along the inside of the linear bearing 203 through the bearing seat 1 205. At the same time, the guide rod 204 also The spring bracket 207 and the metal pick plate 301 are driven to move upward together, causing the spring 208 to compress and store force, and the upward movement of the metal pick plate 301 drives the torque limiting plate 1 303 to move upward together, causing the torque limiting plate 1 303 to separate from the torque limiting plate 2 304, and the multiple key slots 305 to break away from the bite action with the multiple springs 208. At this time, due to the tension of the steel cable 105, the I-shaped wheel 104 is driven to rotate through the winding action of the winding wheel 1 206 and the upper and lower winding wheels 2010, releasing the winding. The remaining portion of the steel cable 105 connected to the inside of the I-shaped wheel 104 eliminates the tension of the steel cable 105. When the tension on the steel cable 105 disappears, the resilience of the spring 208 is released, pushing the spring bracket 207, the guide rod 204, the bearing seat 205 and the winding wheel 206 to reset downward. In addition, the spring bracket 207 also drives the metal pick plate 301 to reset downward, and further drives the torsion limit disc 303 to move downward through the metal pick plate 301 and re-insert into the interior of the circular cavity 307. At the same time, due to the setting of the second guide slope 309 and the first guide slope 306, a guiding effect can be achieved, so that the key slot 305 can slide smoothly and be stuck on the periphery of the key tooth 308. At this time, the torque limiting disk 1 303 is used to limit the torque of the second torque limiting disk 304, resulting in the vertical shaft 103 and the I-shaped wheel 104 being torque limited. The steel cable 105 inside the I-shaped wheel 104 is interrupted and released, ensuring that the steel cable 105 will not accumulate between the tree trunk and the winding wheel 1 206, so that the steel cable 105 has sufficient tension.

[0077] For further details, please refer to Figure 5 As shown:

[0078] The walking unit 400 includes a gear 401, a rack 402, a linear guide 403 and a linear slider 404. The gear 401 is fixedly mounted on the lower part of the outer wall of the vertical shaft 103, the rack 402 is fixedly mounted on the top of the base 101, the rack 402 is meshed with the gear 401, the linear guide 403 is symmetrically distributed about the central axis of the base 101 and is fixed on its top, the linear slider 404 is slidably mounted on the periphery of the linear guide 403, and the top of the linear slider 404 is fixedly connected to the bottom of the walking platform 102.

[0079] Specifically, the rotation of the I-wheel 104 drives the vertical shaft 103 and the gear 401 to rotate. Since the gear 401 is meshed with the rack 402, the gear 401 rotates and rolls along the side of the rack 402, thereby driving the traveling platform 102 to translate along the sliding track of the linear guide 403 and the linear slider 404, resulting in gradually increasing angles R1 and R2. The increasing angle R1 reduces the upward component of the force of the steel cable 105 on the winding wheel 1 206. Therefore, when the tree swings, the winding wheel 1 206 does not move upward. Therefore, under the engagement of the key groove 305 and the key tooth 308, the I-wheel 104 cannot rotate. Therefore, the length of the steel cable 105 between the winding wheel 1 206 and the tree does not change, thereby providing a lateral straightening effect on the tree. The increasing angle R2 causes the horizontal component of the force of the steel cable 105 on the tree to increase, thereby improving the lateral pulling effect on the tree, that is, improving the lateral fixing effect on the tree.

[0080] The present invention provides a landscape tree fixing frame. When working, at least three bases 101 are fixed to the periphery of the tree trunk through channel steel beams, and the angles between the bases 101 are equal. The channel steel beams can be fixed to the ground through ground nails (but not limited to ground nails), and the annular hoop 106 is fixed to the appropriate height of the tree trunk, and the ends of the multiple steel cables 105 are fixedly connected to the surface of the annular hoop 106 through locks (as shown in the attached figure). Figure 1 As shown in FIG), at this time, the angle between the steel cable 105 and the vertical plane of the winding wheel 206 is R1, and the angle between the steel cable 105 and the trunk is R2 (as shown in FIG). Figure 11 As shown in FIG, due to the engagement between the key slot 305 and the key teeth 308, the vertical shaft 103 and the spool 104 cannot rotate. Therefore, the pulling forces of the three steel cables 105 on the tree trunk in multiple directions offset each other, thereby straightening the tree laterally and preventing it from falling sideways.

[0081] When the wind blows the tree trunk to swing to one side, one of the steel cables 105 corresponding to the wind direction is pulled, causing the steel cable 105 to generate a pulling force on the reel 1 206, and the pulling force can be decomposed into a force toward the tree and an upward force. At this time, since the angle R1 is large, the upward force of the steel cable 105 is small and is not enough to pull the reel 1 206 upward. At this time, the pulling force of the steel cable 105 is used to offset the tree swinging force to ensure that the tree will not fall sideways. However, as the tree grows taller, it will drive the annular hoop 106 to move upward, causing the angles of R1 and R2 to gradually increase. The wire rope 105 is stretched due to the force applied to it. As the angle R1 decreases, the upward component of the pulling force of the wire rope 105 on the reel 1 206 increases, causing the reel 1 206 to move upward. The reel 1 206 moves upward and drives the guide rod 204 to slide upward along the inside of the linear bearing 203 through the bearing seat 1 205. At the same time, the guide rod 204 also drives the spring bracket 207 and the metal pick plate 301 to move upward, causing the spring 208 to compress and store force. The upward movement of the metal pick plate 301 drives the torsion limit plate 1 303 to move upward, causing the torsion limit plate 1 303 and the torsion limit plate 2 303 to slide upward. 4 is separated, and the multiple key slots 305 are disengaged from the bite of the multiple springs 208. At this time, due to the tension of the steel cable 105, the I-shaped wheel 104 is driven to rotate through the winding action of the winding wheel 1 206 and the upper and lower winding wheels 2010, releasing the remaining steel cable 105 wound inside the I-shaped wheel 104, thereby eliminating the tension of the steel cable 105. When the tension on the steel cable 105 disappears, the rebound force of the spring 208 is released, pushing the spring bracket 207, the guide rod 204, the bearing seat 1 205 and the winding wheel 1 206 to reset downward. In addition, the spring bracket 207 also drives the metal pick plate 301 downward. After the reset, the metal pick plate 301 is used to further drive the torque limiting disc 1 303 to move downward and re-insert it into the circular cavity 307. At the same time, the setting of the second guide slope 309 and the first guide slope 306 can play a guiding role, so that the key slot 305 can slide smoothly and be stuck on the periphery of the key tooth 308. At this time, the torque limiting disc 1 303 limits the torque of the second torque limiting disc 304, resulting in the vertical shaft 103 and the I-shaped wheel 104 being torque-limited. The steel cable 105 inside the I-shaped wheel 104 is interrupted and released, ensuring that the steel cable 105 does not accumulate between the tree trunk and the winding wheel 1 206, so that the steel cable 105 has sufficient tension.

[0082] At the same time, the rotation of the I-wheel 104 drives the vertical shaft 103 and the gear 401 to rotate. Since the gear 401 meshes with the rack 402, the rotation of the gear 401 causes it to roll along the side of the rack 402, thereby driving the traveling platform 102 to translate along the sliding path of the linear guide 403 and the linear slider 404. This causes the angles R1 and R2 to gradually increase. The increase in the R1 angle reduces the upward component of the force exerted by the steel cable 105 on the winding wheel 1 206. Therefore, when the tree swings, the winding wheel 1 206 does not move upward. Therefore, due to the engagement of the key slot 305 and the key teeth 308, the I-wheel 104 cannot rotate. Therefore, the length of the steel cable 105 between the winding wheel 1 206 and the tree does not change, thereby providing a lateral straightening effect on the tree. The increase in the R2 angle causes the horizontal component of the force exerted by the steel cable 105 on the tree to increase, thereby improving the lateral tension effect on the tree, that is, improving the lateral fixation effect on the tree.

[0083] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
