Description

Technical Field

[0001] The present application relates to the field of garden landscape technology, and in particular to a device for straightening trees that have fallen due to windstorms and a method for using the device. Background Art

[0002] When a windstorm strikes, many trees in landscaping are blown down by the wind. After the storm, sanitation workers use fallen tree straightening devices to straighten the tilted and fallen trees back to their original positions.

[0003] Existing systems for straightening fallen trees typically include strapping and a crane. To straighten a tree, sanitation workers first trim excess branches and leaves from the tree's crown. They then tie the strapping to the trunk, ensuring it's above the tree's center of gravity. They then connect the strapping to a crane hook and activate the crane to lift the tree off the ground. The tree, under its own weight, will then assume a nearly vertical position. Finally, the crane is used to replant the tree in its original location.

[0004] However, when trees are blown down to their leeward side, the roots close to the leeward side of the trees will not be seriously damaged. When the crane lifts the trees off the ground, these relatively intact roots will be pulled out of the soil and damaged, thereby reducing the survival rate of the trees after they are straightened.

[0005] In view of this, it is necessary to provide a high survival rate straightening device for trees fallen by wind disasters and a method for using the device. Summary of the Invention

[0006] In order to solve the problem that the existing fallen tree straightening device may cause damage to the roots of trees when straightening trees, and the survival rate of trees after being straightened is low, the present application provides a high survival rate straightening device for fallen trees caused by wind disasters and a method for use.

[0007] In a first aspect, the present application provides a high-survival-rate righting device for trees fallen by windstorms, which employs the following technical solution: comprising a suspension assembly, a horizontal pull assembly, and a controller; the suspension assembly comprising a suspension unit and a support frame; the suspension unit being capable of connecting to the tree and applying a vertical upward force to the tree; and the suspension unit being slidably connected to the support frame and capable of sliding in a direction toward or away from the windward side of the tree; The horizontal pulling assembly includes a horizontal pulling unit and a detection device, wherein the horizontal pulling unit is capable of being connected to the tree and applying a force to the tree in a horizontal direction close to the windward side of the tree, and the detection device is electrically connected to the controller and is capable of detecting whether the tree has an upward movement trend; The controller is electrically connected to the suspension unit and can control the magnitude of the force applied by the suspension unit to the tree according to the detection result of the detection device.

[0008] By adopting the above technical solution, on the one hand, the suspension unit can apply an upward pulling force to the tree, and the controller can cooperate with the detection component to ensure that the upward pulling force is equivalent to the tree's own weight, so that the tree can be suspended in the current position, thereby ensuring that the parts of the tree's roots remaining in the soil will not be pulled out of the soil and damaged; on the other hand, the horizontal pulling unit can apply a horizontal force close to the windward side of the tree to the tree, so that the main stem of the tree can rotate to a vertical state in the direction close to the windward side of the tree with the roots of the tree remaining in the soil as the center, and during the rotation of the main stem of the tree, the suspension unit will move along the The support frame slides toward the windward side of the tree and ensures that the direction of the upward pulling force on the tree is always vertically upward, so that the upward pulling force can offset the tree's own weight, which can reduce the friction between the parts of the tree's roots that remain in the soil and the surrounding soil, so that these parts will not be easily damaged during the rotation of the main pole, and can prevent the parts of the tree's roots that are exposed outside the soil from being under greater pressure and suffering secondary damage due to the need to share the tree's own weight, so as to effectively reduce the damage to the tree's roots during the straightening process, thereby ensuring that the tree has a good survival rate after being straightened.

[0009] Specifically, the suspension unit includes a suspension member, a drive cylinder and a tension sensor. The suspension member is detachably connected to the tree. A guide rail is provided on the support frame in a direction approaching or moving away from the windward side of the tree. The cylinder body of the drive cylinder is vertically arranged on the guide rail and can slide along the guide rail. The tension sensor is arranged between the piston rod of the drive cylinder and the suspension member and can detect the magnitude of the force applied by the drive cylinder to the suspension member. The controller is electrically connected to the tension sensor.

[0010] By adopting the above technical solution, the drive cylinder can apply an upward pulling force to the tension sensor, the suspension and the tree by retracting the piston rod; since the piston rod of the drive cylinder will gradually retract into the cylinder body during the process of the tree being straightened, the tension sensor can feedback the magnitude of the tension to the controller, so that the controller can control the drive cylinder to always apply the same magnitude of upward pulling force to the tree during the process of the tree being straightened.

[0011] Furthermore, the suspension includes a mounting plate and multiple sets of strapping straps, the tension sensor is arranged on the top of the mounting plate, the piston rod of the driving cylinder is connected to the tension sensor, and a circular slide groove is opened around the center of the bottom of the mounting plate, and multiple sliders are slidably connected in the circular slide groove, and the sliders correspond one-to-one to the strapping straps.

[0012] By adopting the above technical solution, the user can use multiple binding belts to bind multiple primary branches branched off from the main trunk of the tree.

[0013] Furthermore, the strapping belt includes a fixing belt and a connecting belt, one end of the fixing belt is connected to the slider, and the other end of the fixing belt is provided with a buckle, one end of the connecting belt is connected to the slider, and a row of connecting holes is provided on the belt body of the connecting belt along its own length direction, and the buckle can be engaged with any of the connecting holes to connect the connecting belt to the fixing belt.

[0014] By adopting the above technical solution, the user can use the buckle to connect the fixing belt with any connecting hole on the belt body of the connecting belt, so that the binding belt can be used to bundle primary branches of different thicknesses.

[0015] Furthermore, a connecting sleeve is provided on the body of the fixing belt. When the connecting belt is connected to the fixing belt, the end of the connecting belt away from the slider can pass through the connecting sleeve.

[0016] By adopting the above technical solution, after using the buckle to connect the fixing belt to a connecting hole on the belt body of the connecting belt, the user can insert the belt body between the connecting hole and the end of the connecting belt away from the slider into the connecting sleeve, so that this part of the belt body can be limited by the connecting sleeve, thereby making it difficult for the buckle to loosen from the connecting hole.

[0017] Specifically, the horizontal pulling unit includes a connecting member, a slide rail, a sliding sleeve, and a telescopic cylinder. The connecting member can be connected to the tree. The slide rail is vertically arranged on the connecting member. The sliding sleeve is slidably connected to the slide rail. The piston rod of the telescopic cylinder is horizontally arranged and hinged on the sliding sleeve. The detection device is a pressure sensor, which is arranged at the top end of the slide rail and can abut against the slide sleeve.

[0018] By adopting the above technical solution, the telescopic cylinder can apply horizontal force to the sleeve, the slide rail connector and the tree through the piston rod; the user can move the sleeve to a position that abuts the pressure sensor before straightening the tree, and create a certain pressure between the sleeve and the pressure sensor, and then connect the connector to the tree. When the upward pulling force applied by the suspension assembly is greater than the tree's own weight and the tree shows an upward movement trend, the tree will drive the connector and the slide rail to show an upward movement trend. At this time, the reading of the pressure sensor will decrease, so that the controller can judge whether the tree has an upward movement trend based on the change in the reading.

[0019] Furthermore, the horizontal pulling unit further includes an elastic member, which is connected to the sliding sleeve and can apply a force to the sliding sleeve to approach the pressure sensor.

[0020] By adopting the above technical solution, the elastic member can apply a force to the sliding sleeve close to the pressure sensor, so that before the tree is straightened, there is a relatively stable pressure between the sliding sleeve and the pressure sensor, which makes it easier for the controller to judge whether the tree has an upward movement trend based on the change in pressure.

[0021] Furthermore, the connecting part includes a binding belt and a connecting belt, one end of the binding belt is connected to the slide rail, a row of plug holes are provided on the belt body of the binding belt along its length direction, one end of the connecting belt is connected to the slide rail, and the other end of the connecting belt is provided with a snap buckle, and the snap buckle can be snapped into any of the plug holes.

[0022] By adopting the above technical solution, the user can use the snap buckle to connect the receiving belt with any plug hole on the belt body of the binding belt, so that the connecting piece can bundle tree trunks of different thicknesses.

[0023] Specifically, it also includes a moving component, which includes a vehicle body and wheels. The support frame, the flat pulling unit and the controller are all connected to the vehicle body. The wheels are arranged between the vehicle body and the ground and are rotatably connected to the vehicle body.

[0024] By adopting the above technical solution, the high survival rate straightening device for trees fallen by wind disasters can be moved through the setting of the vehicle body and wheels, so that the high survival rate straightening device for trees fallen by wind disasters can be used to straighten fallen trees in different areas.

First, connect the horizontal pulling unit and the suspension unit to the tree to be straightened and ensure that the center of gravity of the tree is located between the connection points between the horizontal pulling unit and the tree and the connection points between the suspension unit and the tree.

Finally, repair the wound of the tree's roots exposed on the ground. S2, starting the suspension unit to apply a gradually increasing upward pulling force to the tree, and when the detection device detects that the tree has an upward movement trend, controlling the suspension unit through the controller to maintain the magnitude of the upward pulling force unchanged; S3, starting the horizontal pulling unit to apply a horizontal force to the tree near the windward side of the tree until all the roots of the tree enter the tree hole and the tree is in a vertical state; S4. Close the horizontal pulling unit and the suspension unit, and fill and compact the tree hole of the tree.

[0026] By adopting the above technical solution, digging up the accumulated soil in the tree hole on the windward side of the tree before the tree falls can facilitate the roots of the tree exposed outside the soil to return to the tree hole; digging up the accumulated soil in the tree hole on the leeward side of the tree can reduce the friction between the parts of the tree's roots remaining in the soil and the surrounding soil, so that these parts will not be easily damaged during the rotation of the main pole; repairing the wounds of the tree's roots exposed on the ground can reduce the risk of infection and withering at the wounded parts of the roots, so as to further increase the survival rate of the tree after straightening.

[0036] The pressure sensor, the drive cylinder 112, the telescopic cylinder 214 and the tension sensor 113 are all electrically connected to the controller, and the control logic of the controller is: After the user connects the connecting piece to the main pole of the tree 4 and connects the three sets of straps on the suspension plate to a first-level branch 42, the controller will first control the drive cylinder 112 to retract the piston rod to apply an upward pulling force to the tension sensor 113, the suspension piece and the tree 4, and the tension sensor 113 will detect the magnitude of the upward pulling force in real time and feed back the detection result to the controller; when the upward pulling force applied by the drive cylinder 112 is greater than the weight of the tension sensor 113, the suspension piece and the tree 4, the tree 4 will drive the connecting piece, the slide rail 212 and the pressure sensor to show an upward movement trend. At this time, the reading of the pressure sensor will decrease, so that the controller can judge that the tree 4 has an upward movement trend and record the magnitude of the upward pulling force detected by the tension sensor 113 at this time; then the controller will start the telescopic cylinder 214 to retract the piston rod to apply a horizontal force to the sleeve 213, the slide rail 212 connecting piece and the tree 4, so that the main pole of the tree 4 can move toward the center with the root of the tree 4 left in the soil as the center. 4 and 4. The sling 112 of the present invention is a kind of sling 110 that is used for the purpose of adjusting the weight of the tree 4 so as to prevent the sling 110 from being damaged and the sling 110 from being damaged.

[0037] Based on the structure of the above-mentioned wind-fallen tree straightening device with a high survival rate, the second aspect of the present application further provides a method for using the wind-fallen tree straightening device with a high survival rate. The method is implemented using the above-mentioned wind-fallen tree straightening device with a high survival rate, and the method specifically includes: S1. First, connect the horizontal pulling unit 21 and the suspension unit 11 to the tree 4 to be straightened, and ensure that the center of gravity of the tree 4 is located between the connection points between the horizontal pulling unit 21 and the tree 4 and the connection points between the suspension unit 11 and the tree 4. Then, remove the accumulated soil in the tree hole on the windward side 43 of the tree 4, and loosen the accumulated soil in the tree hole on the leeward side 44 of the tree 4. Finally, repair the wounds of the roots of the tree 4 exposed on the ground. S2. Start the suspension unit 11 to apply a gradually increasing upward pulling force to the tree 4. When the detection device 22 detects that the tree 4 has an upward movement trend, the controller controls the suspension unit 11 to maintain the magnitude of the upward pulling force unchanged. S3, start the horizontal pulling unit 21 to apply a horizontal force to the tree 4 close to the windward side 43 of the tree 4 until the roots of the tree 4 are all in the tree hole and the tree 4 is in a vertical state; S4, closing the horizontal pulling unit 21 and the suspension unit 11, and filling and compacting the tree hole of the tree 4.

[0038] Since the method of using the device for straightening trees fallen by wind with a high survival rate in the present application is implemented by the above-mentioned device for straightening trees fallen by wind with a high survival rate, it can also have all the technical effects of the above-mentioned device for straightening trees fallen by wind with a high survival rate, especially digging up the accumulated soil in the tree hole on the windward side 43 of the tree 4 before the tree 4 falls, which can facilitate the roots of the tree 4 exposed outside the soil to return to the tree hole; loosening the accumulated soil in the tree hole on the leeward side 44 of the tree 4 can reduce the friction between the parts of the roots of the tree 4 that remain in the soil and the surrounding soil, so that these parts will not be easily damaged during the rotation of the main pole; repairing the wounds of the roots of the tree 4 exposed on the ground can reduce the risk of infection and withering at the wounded parts of the roots, so as to further increase the survival rate of the tree 4 after straightening.

[0039] Specifically, the operation of wound repairing the rhizome may include the following steps: For tree roots with a fracture area less than 1 / 2, you can first smooth the fracture surfaces on both sides of the roots, then apply disinfectant, then connect the fractures and apply protective agent, and finally tie the wound tightly with a film; for tree roots with a fracture area greater than 1 / 2, you can first cut off the broken roots along the fracture, then saw the ends of the roots flat, apply disinfectant and protective agent on the wound surface, and finally tie the wound tightly with a film; and for rotten roots, damaged roots and completely broken roots, they should be pruned together, and disinfectant and protective agent should be applied to the wounds caused by pruning.

[0040] It should be noted that when the crown of tree 4 is large and the roots are severely damaged, the inner branches, overgrown branches, overlapping branches and other small branches of the crown can be pruned, so as to reduce the weight of tree 4, reduce the pressure on the roots and the burden of nutrient supply, and thus improve the survival rate of tree 4 after straightening.

[0041] The implementation principle of the high survival rate straightening device for fallen trees caused by wind disasters described in this application is: After the user connects the connecting piece to the main pole of the tree 4 and connects the three sets of strapping belts on the suspension plate to a first-level branch 42, the controller will first control the driving cylinder 112 to retract the piston rod to apply an upward pulling force to the tension sensor 113, the suspension piece and the tree 4, and the tension sensor 113 will detect the magnitude of the upward pulling force in real time and feed back the detection result to the controller; when the upward pulling force applied by the driving cylinder 112 is greater than the dead weight of the tension sensor 113, the suspension piece and the tree 4, the tree 4 will drive the connecting piece, the slide rail 212 and the pressure sensor to move upward. At this time, the reading of the pressure sensor will decrease, so that the controller can determine that the tree 4 has an upward movement trend and record the magnitude of the upward pulling force detected by the tension sensor 113 at this time; Then the controller will start the telescopic cylinder 214 to retract the piston rod to apply a horizontal force to the sliding sleeve 213, the sliding rail 212 connector and the tree 4, so that the main stem of the tree 4 can rotate to a vertical state with the root of the tree 4 remaining in the soil as the center toward the windward side 43 of the tree 4. During the rotation of the main stem of the tree 4, the suspension unit 11 as a whole will slide along the crossbeam 122 toward the windward side 43 of the tree 4 as the tree 4 rotates, so as to ensure that the direction of the upward pulling force on the tree 4 is always vertically upward. During the sliding of the suspension unit 11, the controller will The driving cylinder 112 and the tension sensor 113 cooperate to ensure that the upward pulling force on the tree 4 remains unchanged, so that the upward pulling force can offset the weight of the tree 4. This can reduce the friction between the parts of the roots of the tree 4 that remain in the soil and the surrounding soil, so that these parts will not be easily damaged during the rotation of the main pole. It can also prevent the parts of the roots of the tree 4 that are exposed outside the soil from being under greater pressure and suffering secondary damage due to the need to share the weight of the tree 4, so as to effectively reduce the damage to the roots of the tree 4 during the straightening process, thereby ensuring that the tree 4 has a good survival rate after being straightened.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
