Description

Technical Field

[0001] The present invention relates to the technical field of sapling planting, and particularly to a sapling anti-tipping and righting device and an installation method thereof. Background Technique

[0002] With the increasing demand for urban greening and forestry development, the planting and maintenance of saplings have become particularly important. Especially in the initial growth stage of saplings, due to the relatively thin trunk and the incomplete development of the root system, they are easily affected by external factors and prone to tipping or tilting. This not only affects the normal growth of saplings but also reduces the greening effect. Therefore, it is necessary to use a support device to right them and prevent the saplings from tipping.

[0003] Most of the existing sapling anti-tipping and righting devices are fixed support structures. Such devices usually use metal or wooden support rods, which are directly inserted into the ground and fixed to the saplings. This kind of device has a simple structure but is not easy to adjust. If the clamping is too tight, it is difficult to adapt to the changes during the growth of saplings, and it is easy to damage the bark and limit the development of saplings. If the clamping is too loose, in the face of strong wind weather, the support effect is not good, and it is easy to cause the saplings to sway or even tip over. Therefore, a sapling anti-tipping and righting device and an installation method thereof are needed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a sapling anti-tipping and righting device and an installation method thereof, which have the advantages of being able to adaptively adjust and having good wind resistance, and solve the problems that the existing sapling anti-tipping and righting devices cannot adaptively adjust the clamping force, resulting in restricted growth of saplings or easy tipping of saplings in strong wind weather.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A sapling anti-tipping and righting device includes a fixed base, a support sleeve, and a connecting rod.

[0007] Preferably, as a sapling anti - tipping and righting device of the present invention, the wind - sensing frame includes a wind - direction plate, a pointing rod, and a connecting ring. The pointing rod is fixedly installed at the front end of the upper end surface of the connecting ring, and the wind - direction plate is fixedly installed at the rear end of the upper end surface of the connecting ring. The support block is installed on the lower end surface of the connecting ring near the wind - direction plate.

[0009] Preferably, as a sapling anti - tipping and righting device of the present invention, the support block is an arc - shaped vertical plate. The edge of the front end surface of the support block is rounded, and a rotating roller is rotatably connected to the front end surface of the support block.

[0010] Preferably, as a sapling anti - tipping and righting device of the present invention, the pressure - applying mechanism includes a hydraulic oil pot, a turntable, a swing block, and an elastic diaphragm. A first rotating shaft is provided at the top of the turntable, and the turntable is rotatably connected to the hydraulic oil pot through the first rotating shaft. A second sliding groove matching the swing block is provided on the side surface of the turntable. The swing block is installed in the second sliding groove and slidably connected to the turntable. The elastic diaphragm is coated on the outer end of the swing block. An oil discharge port is provided at the bottom of the side end surface of the hydraulic oil pot.

[0011] Preferably, as a sapling anti - tipping and righting device of the present invention, a second rotating shaft is provided at the center of the fan blade. The second rotating shaft is rotatably connected to the wind - sensing frame, and the first rotating shaft and the second rotating shaft are meshed and connected by a gear and a bevel gear.

[0012] Preferably, as a sapling anti - tipping and righting device of the present invention, a piston cavity is provided on the inner end surface of the support block, a piston plate is slidably connected in the piston cavity, and a hydraulic oil flow channel is provided between the piston cavity and the oil discharge port.

[0013] Preferably, as a sapling anti - tipping and righting device of the present invention, the elastic airbag is an open - type circular ring structure. Nylon fiber cloth is provided on the outside of the elastic airbag, and the elastic airbag is made of elastic silicone rubber.

[0014] An installation method of a sapling anti - tipping and righting device includes the following steps: Step 1: Assemble the base, connect the first chassis and the second chassis through hinges and fix them around the roots of the saplings with bolts; Step 2: When assembling the support sleeve, the first and second rings are connected by hinges and sleeved on the outside of the sapling. At this time, the bolts on the support sleeve are not installed. Step 3: Install the wind sensing bracket, and install the wind sensing bracket in the first ring through the slider and the annular slide groove, so that the wind sensing bracket can slide along the upper end surface of the support sleeve; Step 4: assemble the fixed base, the support sleeve and the connecting rod, install the connecting rod at the corresponding positions of the fixed base and the support sleeve, and fix the support sleeve to the base through the connecting rod; Step 5. Place the elastic airbag into the support sleeve and pay attention to the direction of the opening, so that the elastic airbag is stuck in the support sleeve under the action of air pressure. At this time, gradually tighten the bolts on the first ring and the second ring, so that the elastic airbag squeezes the branches of the sapling to support it.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can adaptively adjust according to the size and growth conditions of the seedlings by arranging an elastic airbag in the support sleeve. The seedlings will not be skewed due to excessive clearance between the seedlings and the support sleeve, or the support sleeve will not restrain the seedlings too tightly, causing damage to the seedling bark and affecting the growth of the seedlings. The needs of different growth stages are met, the number of times equipment is replaced, and the cost of long-term use is reduced.

[0016] 2. The present invention cooperates with the wind sensing frame and the support block. The wind sensing frame always points to the direction of the incoming wind, thereby driving the support block to rotate toward the leeward side of the sapling, thereby strengthening the support for the leeward side of the sapling, reducing the elastic deformation space on the leeward side of the elastic airbag, and better controlling the swing amplitude of the sapling, reducing the shaking caused by wind, and further improving the stability of the equipment support.

[0017] 3. The present invention cooperates with the wind sensing frame, fan blades, pressure-supplying mechanism and support blocks to make the fan blades drive the turntable to rotate, so that the swinging blocks on the side walls of the turntable are thrown outward under the action of centrifugal force, increasing the oil discharge volume of the elastic diaphragm and causing the piston plate to extend outward, thereby further squeezing the elastic airbag and increasing the restraint of the elastic airbag on the seedlings. As the wind force increases, the speed of the turntable increases, the distance the swinging blocks are thrown increases, and the pressure applied to the elastic airbag by the piston plate also increases accordingly. The better the support stability, the pressure of the elastic airbag on the seedlings can be automatically adjusted by the pressure-supplying mechanism, which can effectively reduce the swing amplitude of the seedlings under the action of wind force and improve the stability of the overall system.

Detailed implementation manners

[0020] Embodiment 1 Please refer to Figures 1 - 10 , a sapling anti - tipping and righting device, comprising a fixed base 1, a support sleeve 2 and a connecting rod 3. An elastic airbag 4 and a wind prevention mechanism 5 are arranged inside the support sleeve 2; The fixed base 1 includes a first chassis 101, a second chassis 102 and a ground nail 104. The fixed base 1 is installed at the lower end of the connecting rod 3; The support sleeve 2 includes a first collar 201 and a second collar 202. The support sleeve 2 is installed at the upper end of the connecting rod 3; The elastic airbag 4 is movably installed on the inner end face of the support sleeve 2; The wind prevention mechanism 5 includes a wind sensing frame 501, fan blades 502, a pressure applying mechanism 503 and a support block 504. The wind prevention mechanism 5 is installed between the support sleeve 2 and the elastic airbag 4 and is rotatably connected to the support sleeve 2.

[0021] Further, the first chassis 101 and the second chassis 102, as well as the first collar 201 and the second collar 202, are rotatably connected by hinges. The ends of the first and second chassis 102 away from the hinges and the ends of the first collar 201 and the second collar 202 away from the hinges are fixed by bolts. Ear plates 103 are provided on the upper end face of the fixed base 1 and the lower single face of the support sleeve 2. The upper and lower ends of the connecting rod 3 are fixed to the ear plates 103 by bolts.

[0022] The assembled fixed base 1, support sleeve 2 and connecting rod 3 mechanism enable the entire device to be disassembled and stored during use, thereby reducing the overall space occupied by the equipment and improving the convenience of the equipment. The hinge-type assembled structure also facilitates the rapid assembly and cooperation of the equipment, improving the convenience of equipment installation.

[0023] Further, the wind sensing frame 501 includes a wind direction plate 5011, a pointing rod 5013 and a connecting ring 5012. The pointing rod 5013 is fixedly installed at the front end of the upper end face of the connecting ring 5012, and the wind direction plate 5011 is fixedly installed at the rear end of the upper end face of the connecting ring 5012. The support block 504 is installed on the lower end face of the connecting ring 5012 near the wind direction plate 5011 end.

[0024] Through the cooperation of the wind direction plate 5011 and the pointing rod 5013, when the wind blows towards the sapling, the pointing rod 5013 always faces the direction from which the wind blows, thereby driving the support block 504 to move to the leeward side of the sapling to provide support for the sapling and improve the wind prevention performance of the sapling.

[0025] Further, an annular chute 203 is provided on the inner end face of the support sleeve 2, a slider 5041 that cooperates with the annular chute 203 is provided on the back surface of the support block 504, and the connecting ring 5012 is a semi-circular ring structure.

[0026] Through the cooperation of the slider 5041 and the annular chute 203, the smoothness and stability of the rotation of the wind sensing frame 501 are improved. The open connection structure enables the wind sensing frame 501 to be easily removed from the tree trunk when the equipment is disassembled, avoiding the situation where the wind sensing frame 501 gets stuck on the tree trunk and cannot be removed after the tree trunk grows.

[0027] Further, the support block 504 is a circular arc-shaped vertical plate, the edge of the front end face of the support block 504 is chamfered, and a rotating roller 5042 is rotatably connected to the front end face of the support block 504.

[0028] The arc-shaped support block 504 is structured to better fit the outer side of the elastic airbag 4 and can provide more stable support for the sapling. The rounded corners are processed to prevent the support block 504 from cutting or jamming the elastic airbag 4 during sliding. By providing rotating rollers 5042 rotatably connected on both sides of the support block 504, the friction between the support block 504 and the elastic airbag 4 is reduced, making the wind-sensing bracket slide more smoothly.

[0029] Further, the pressing mechanism 503 includes a hydraulic oil pot 5031, a turntable 5032, a flyweight 5034, and an elastic diaphragm 5033. A first rotating shaft 50321 is provided at the top of the turntable 5032. The turntable 5032 is rotatably connected to the hydraulic oil pot 5031 through the first rotating shaft 50321. A second sliding groove 50322 cooperating with the flyweight 5034 is provided on the side surface of the turntable 5032. The flyweight 5034 is installed in the second sliding groove 50322 and slidably connected to the turntable 5032. The elastic diaphragm 5033 is wrapped around the outer end of the flyweight 5034. An oil drain port 50311 is provided at the bottom of the side end surface of the hydraulic oil pot 5031.

[0030] The elastic diaphragm 5033 is made of elastic silica gel or rubber. When the first rotating shaft 50321 rotates, the flyweight 5034 is thrown outwards under the action of centrifugal force, thereby expanding the elastic diaphragm 5033 outwards, increasing the oil discharge volume of the elastic diaphragm 5033, and thus pressing the hydraulic oil out through the oil drain port 50311 and flowing along the hydraulic oil passage to the piston plate 5044. Moreover, the higher the rotation speed, the greater the centrifugal force on the flyweight 5034, the greater the deformation of the elastic diaphragm 5033, the greater the discharged volume of the hydraulic oil, and the greater the pressure exerted by the piston plate 5044 on the elastic airbag 4, and the pressure of the elastic airbag 4 on the sapling increases with the increase of wind force.

[0031] Further, a second rotating shaft 5021 is provided at the center of the fan blade 502. The second rotating shaft 5021 is rotatably connected to the wind-sensing frame 501. The first rotating shaft 50321 and the second rotating shaft 5021 are connected by spur gears in mesh.

[0032] When the wind blows towards the fan blade 502, the airflow drives the fan blade 502 to rotate, thereby driving the second rotating shaft 5021 to rotate. Through the spur gears in mesh, the first rotating shaft 50321 is driven to rotate, thereby driving the turntable 5032 to rotate. Thus, the rotation speed of the turntable 5032 is proportional to the wind speed, and the flyweight 5034 on the turntable 5032 is thrown out farther with the increase of wind force.

[0033] Further, a piston chamber 5043 is provided on the inner end surface of the support block 504. A piston plate 5044 is slidably connected in the piston chamber 5043. A hydraulic oil flow passage 5014 is provided between the piston chamber 5043 and the oil drain port 50311.

[0034] After the hydraulic oil in the hydraulic oil pot 5031 is pressed out by the flyweight 5034 and the elastic diaphragm 5033, it flows along the hydraulic flow path to the piston cavity 5043. Under the pressure of the hydraulic oil, the piston plate 5044 is pushed outwards, so that the piston plate 5044 squeezes the elastic airbag 4, and the elastic airbag 4 undergoes elastic deformation, thereby firmly clamping the sapling, preventing the tree trunk from swinging repeatedly under the action of wind, causing the root to loosen and affecting the survival rate of the sapling.

[0035] Further, the elastic airbag 4 is an open circular ring structure. The outer side of the elastic airbag 4 is provided with a nylon fiber cloth 401, and the elastic airbag 4 is made of elastic silica gel rubber.

[0036] The open elastic airbag 4 structure enables the support sleeve 2 to be disassembled, and the elastic airbag 4 can also be removed from the tree trunk. And the nylon fiber cloth 401 is arranged on the outer side of the elastic airbag 4, which can effectively prevent the protrusions on the sapling from piercing the airbag and can improve the weather resistance of the airbag.

[0037] Embodiment 2 Please refer to Figures 1 - 10 , an installation method of a sapling anti-tipping and straightening device, including the following steps: Step 1, base assembly, connect the first chassis 101 and the second chassis 102 through a hinge and fix them with bolts around the root of the sapling; Step 2, support sleeve 2 assembly, connect the first collar 201 and the second collar 202 through a hinge and sleeved on the outside of the sapling. At this time, the bolts on the support sleeve 2 are not installed; Step 3, wind-sensing bracket installation, install the wind-sensing frame 501 in the first collar 201 through the slider 5041 and the annular chute 203, so that the wind-sensing frame 501 can slide along the upper end surface of the support sleeve 2; Step 4, assembly of the fixed base 1, the support sleeve 2 and the connecting rod 3, install the connecting rod 3 at the corresponding positions of the fixed base 1 and the support sleeve 2, and fix the support sleeve 2 to the base through the connecting rod 3; Step 5, put the elastic airbag 4 into the support sleeve 2 and pay attention to the opening direction, so that the elastic airbag 4 is stuck in the support sleeve 2 under the action of air pressure. At this time, gradually tighten the bolts on the first collar 201 and the second collar 202, so that the elastic airbag 4 squeezes the sapling branches to support it.

[0038] During the natural growth process of the sapling, the elastic airbag 4 protects the side wall of the sapling, preventing it from tilting under its own gravity. As the sapling grows, the branches of the sapling squeeze the airbag, causing the airbag to undergo elastic deformation, thus avoiding the generation of cumulative marks on the side wall of the tree trunk and affecting the health of the sapling. In strong convective weather, when the wind blows towards the sapling, through the cooperation of the wind vane 5011 and the pointing rod 5013, the support block 504 is driven to move to the leeward direction of the sapling to provide support for the sapling. At the same time, the fan blade 502 starts to rotate. The fan blade 502 is rotationally connected to the wind sensing frame 501 through the second rotating shaft 5021, and then drives the first rotating shaft 50321 to rotate through the gear. With the rotation of the fan blade 502, the first rotating shaft 50321 drives the turntable 5032 to rotate. The throwing block 5034 is thrown outwards under the action of centrifugal force, causing the elastic diaphragm 5033 to expand outwards, increasing the oil discharge volume. The hydraulic oil is pressed out and enters the hydraulic oil channel through the oil discharge port 50311, and finally pushes the piston plate 5044 to squeeze the elastic airbag 4, so that the elastic airbag 4 squeezes the inner wall of the tree trunk in the limited space of the support sleeve 2 to provide more stable support for it. As the wind force increases, the rotation speed of the turntable 5032 increases, the throwing distance of the throwing block 5034 increases, and the pressure exerted by the piston plate 5044 on the elastic airbag 4 also increases accordingly, thereby increasing the support force for the sapling.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
