[0001] The invention relates to the technical field of tree lifting frames, in particular to a tree lifting frame and a lifting method for garden engineering. Background Art

[0002] In urban greening projects, since it is difficult to cultivate seedlings from a young age, trees in forest farms or suburbs are usually transplanted, which greatly speeds up the greening process. However, trees need to be treated with caution during the transplanting and hoisting process to ensure the survival rate of the transplant.

[0003] Currently, tree transplanting requires multiple trial lifts, which is time-consuming and labor-intensive. It is troublesome to adjust the tree to a horizontal state when lifting it. In addition, after lifting, since the lifted tree is in a horizontal state, it is difficult to put the tree into the tree hole in a vertical posture. Multiple manual interventions are required, and the efficiency of tree lifting and transplanting is low. Therefore, there is an urgent need for a tree lifting frame for garden engineering to improve transplanting efficiency and survival rate. Summary of the invention

[0004] In order to solve the above-mentioned problems, the present invention provides a tree lifting frame and a lifting method for garden engineering.

[0006] The lifting mechanism includes a bracket hingedly installed in the middle of the top end of the sliding frame, a horizontal sensor installed on the bracket, a lifting ring symmetrically fixed on the top end of the bracket, side panels symmetrically fixed on both sides of the sliding frame, a driving member installed on the bracket, and a toothed belt with one end rotatably installed on the side panel on one side of the sliding frame and the other end bypassing the driving member and rotatably installed on the side panel on the other side of the sliding frame.

[0007] In a preferred example, the present invention can be further configured as follows: the tightening member includes a second clamping block arranged on one side of the lifting frame and an electric telescopic rod installed on the lifting frame and with an end fixedly connected to the second clamping block.

[0008] By adopting the above technical solution, the second clamping block is used to fix one end of the strap. At the same time, when the electric telescopic rod drives the second clamping block to move upward, it can drive the strap to be tightened, thereby fixing the tree on the lifting frame, realizing automatic tightening of the strap, avoiding the trouble and time-consuming labor of manual tightening, and reducing the labor intensity of workers.

[0018] By adopting the above technical solution, when the second motor is started, it can drive the gear to rotate, and the rotation of the gear drives the toothed belt to rotate. At this time, the toothed belt on one side is shortened, and the toothed belt on the other side is extended, driving the sliding frame to rotate, and the rotation of the sliding frame drives the lifting frame to rotate, that is, driving the tree fixed on the lifting frame to rotate, and changing the tree from a horizontal state to a vertical state.

[0020] By adopting the above technical solution, the horizontal sensor can adjust the moving direction and position of the sliding frame according to the monitored trees.

[0021] In a second aspect, the present invention provides a method for hoisting trees for garden engineering, comprising: One end of the hoisting frame strap is inserted into the first slot of the first clamping block, and after the strap passes around the appropriate position of the tree, the other end of the strap is inserted into the second slot of the tightening member; The electric telescopic rod of the tightening member is started, and the electric telescopic rod drives the second clamping block to move upward, so that the binding belt is gradually tightened until the tree is firmly fixed on the lifting frame; The first motor is started, the first motor drives the roller to rotate, the roller drives the transmission belt to move, and the transmission belt drives the sliding frame to move in the sliding groove of the lifting frame; Starting the lifting frame, which slowly lifts the tree off the ground, and when the tree is lifted to a suitable position, starting the second motor; The second motor drives the gear of the driving member to rotate, and the gear drives the toothed belt to rotate, the toothed belt on one side is shortened, and the toothed belt on the other side is extended, so that the sliding frame rotates around the connecting seat, thereby driving the lifting frame and the tree fixed on the lifting frame to change from a horizontal state to a vertical state; Start the electric telescopic rod of the tightening member, loosen the strap, remove the strap from the first clamping block and the second clamping block, and complete the tree unloading.

[0022] In summary, the present invention has the following beneficial technical effects: 1. In the present invention, the lifting frame is lengthened so that there are more fixing points between it and the tree. When the tree is lifted in a horizontal state, the toothed belts on both sides of the driving member are of equal length to ensure the stability of the lifting frame. When the tree is lifted in a horizontal state, the driving member is started to drive the toothed belt to rotate. At this time, the toothed belt on one side is shortened and the toothed belt on the other side is extended, driving the sliding frame to rotate. The rotation of the sliding frame drives the lifting frame to rotate, that is, drives the tree fixed on the lifting frame to rotate, and transforms the tree from a horizontal state to a vertical state, so that the tree can be directly placed in the tree hole in a vertical posture later. No manual intervention is required throughout the process, and the horizontal and vertical states of the tree can be automatically adjusted, effectively improving the efficiency of tree lifting and transplantation.

[0023] 2. In the present invention, during the lifting process, since one side of the tree is heavier and the other side is lighter, the entire lifting frame is in a tilted state. At this time, the horizontal sensor detects the tilt angle and starts the first motor. The first motor starts to drive the roller on one side to rotate, and the rotation of the roller drives the transmission belt to rotate. The rotation of the transmission belt drives the sliding frame to move on the lifting frame, and the position of the sliding frame is adjusted. The purpose is to place the center of gravity of the tree at the center point of the sliding frame on the same vertical line. As the sliding frame moves, the tilt angle monitored by the horizontal sensor becomes smaller and smaller. When it reaches a horizontal state, the center of gravity of the tree at the center point of the sliding frame is on the same vertical line. The tree is lifted in a horizontal state, and the horizontal state of the tree can be automatically adjusted during the lifting process without multiple trial liftings, thereby further increasing the lifting efficiency and the stability of the lifting.

[0024] 3. In the present invention, a plurality of first clamping blocks are arranged in an array on one side of the lifting frame, a plurality of second clamping blocks are arranged in an array on the other side of the lifting frame, and a binding strap is provided. When tying a tree, it is only necessary to engage one end of the binding strap into the first clamping block and the other end into the second clamping block. Then, the electric telescopic rod drives the second clamping block to move upward to tighten the binding strap. The binding strap is tightened to fix the tree on the lifting frame, and the binding strap is automatically tightened without manual tightening. This greatly reduces the workload of workers during lifting and reduces the labor intensity of workers. At the same time, the binding strap is easy to install and disassemble, and can be replaced immediately after damage. In addition, a rubber pad is fixed at the bottom end of the lifting frame, which can further increase the contact area between the lifting frame and the tree, and enhance the friction between the two, thereby ensuring that the tree will not slide off the lifting frame when it is transformed from a horizontal state to a vertical state.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] Example 1 like Figure 1-Figure 5 As shown, a tree lifting frame for garden engineering includes: a main body mechanism 100 and a lifting mechanism 200.

[0029] Among them, the main mechanism 100 includes a lifting frame 110, multiple groups of first blocks 120 fixed in an array on one side of the lifting frame 110, multiple tightening members 130 installed in an array at the other end of the lifting frame 110, a rubber pad 140 fixed at the bottom end of the lifting frame 110, a strap 150 with one end embedded in the first block 120 and the other end embedded in the tightening, a sliding frame 160 slidably embedded in the lifting frame 110, rollers 170 symmetrically fixed on both sides of the lifting frame 110, a first motor 180 installed on one side of the roller 170, and a transmission belt 190 with one end fixed on one side of the sliding frame 160 and the other end passing through the rollers 170 on both sides and fixed on the other side of the sliding frame 160.

[0030] The lifting frame 110 is designed to be elongated, which can provide more positions for fixing to the tree, thereby ensuring the stability of the fixation between the lifting frame 110 and the tree. The two first blocks 120 are a group, which are used to fix one end of the strap 150. The tightening member 130 is used to fix the other end of the strap 150 and drive the strap 150 to tighten, thereby fixing the tree on the lifting frame 110.

[0031] The tightening member 130 includes a second block 131 arranged on one side of the lifting frame 110 and an electric telescopic rod 132 installed on the lifting frame 110 and fixedly connected to the second block 131 at one end. Through holes are arranged in an array on one side of the lifting frame 110. The second block 131 corresponds to the position of the through holes, so that the second block 131 can pass through the through holes and move upward. The electric telescopic rod 132 is symmetrically arranged on both sides of the second block 131, and the top end is fixed to the top end of the second block 131, so as to drive the second block 131 to move.

[0032] The binding belt 150 is used to fix the tree on the lifting frame 110, and includes a fiber lifting belt 151 and a cylinder 152 fixed at both ends of the fiber lifting belt 151. A first slot 121 is opened on one side of the first block 120, and a second slot 1311 is opened on one side of the second block 131. At the same time, the cylinder 152 at one end of the fiber lifting belt 151 is embedded in the first slot 121, and the cylinder 152 at the other end is embedded in the second slot 1311, so that the two ends of the binding belt 150 can be quickly and conveniently embedded in the first block 120 and the second block 131, which increases the convenience of installation and disassembly of the binding belt 150.

[0033] The rubber pad 140 is fixed to the bottom of the lifting frame 110, and its bottom end surface is set to be frosted, which can further increase the contact area between the lifting frame 110 and the tree, and enhance the friction between the two, thereby ensuring that the tree will not slide off the lifting frame 110 when transforming from a horizontal state to a vertical state.

[0034] A slide groove 111 is arranged on the lifting frame 110, and the sliding frame 160 includes a frame 161 slidably engaged in the slide groove 111 and a connecting seat 162 fixed at the middle of the top end of the frame 161. By sliding the sliding frame 160 on the lifting frame 110, the lifting position of the tree can be adjusted, so that the center of gravity of the tree at the center point of the sliding frame 160 is conveniently located on the same vertical line, so that the tree can be kept in a horizontal state when lifted.

[0035] The roller 170 is used to install the transmission belt 190, including a fixed frame 171 symmetrically fixed on one side of the lifting frame 110 and a rotating shaft 172 rotatably installed between the relatively fixed frames 171. The first motor 180 is installed on the fixed frame 171 on one side, and the shaft is fixedly connected to the end of the rotating shaft 172. At the same time, one end of the transmission belt 190 is fixed to one side of the sliding frame 160, and the other end passes through the rotating shafts 172 on both sides and is fixed to the other side of the sliding frame 160. When the first motor 180 drives the rotating shaft 172 to rotate, it can drive the transmission belt 190 to rotate, and the rotation of the transmission belt 190 can drive the sliding frame 160 to move on the lifting frame 110.

[0036] The lifting mechanism 200 is installed on the sliding frame 160, including a bracket 210 hingedly installed in the middle of the top of the sliding frame 160, a horizontal sensor 220 installed on the bracket 210, a lifting ring 230 symmetrically fixed on the top of the bracket 210, side panels 240 symmetrically fixed on both sides of the sliding frame 160, a driving member 250 installed on the bracket 210, and a toothed belt 260 having one end rotatably installed on the side panel 240 on one side of the sliding frame 160 and the other end bypassing the driving member 250 and rotatably installed on the side panel 240 on the other side of the sliding frame 160.

[0037] The bottom end of the bracket 210 is rotatably connected to the connecting seat 162 on the frame 161 to facilitate the rotation of the sliding frame 160. The horizontal sensor 220 is used to monitor the horizontal state of the lifting frame 110 in real time, and the output end of the horizontal sensor 220 is electrically connected to the input end of the first motor 180 through an electric wire. During the lifting process, since one side of the tree is heavier and the other side is lighter, the entire lifting frame 110 is in a tilted state. At this time, the horizontal sensor 220 detects the tilt angle and starts the first motor 180. The first motor 180 starts to drive the roller 170 on one side to rotate. The rotation of the roller 170 drives the transmission belt 190 to rotate. The rotation of the transmission belt 190 drives the sliding frame 160 to move on the lifting frame 110. The position of the sliding frame 160 is adjusted to place the center of gravity of the tree at the center point of the sliding frame 160 on the same vertical line. As the sliding frame 160 moves, the tilt angle monitored by the horizontal sensor 220 becomes smaller and smaller. When it reaches a horizontal state, the center of gravity of the tree at the center point of the sliding frame 160 is on the same vertical line, and the tree is lifted in a horizontal state.

[0038] The side plate 240 is used to mount one end of the toothed belt 260. The driving member 250 is used to drive the toothed belt 260 to rotate. The rotation of the toothed belt 260 is used to adjust the posture of the sliding frame 160, that is, to adjust the posture of the lifting frame 110. The driving member 250 includes a gear 251 rotatably mounted on the inner side of the bracket 210 and a second motor 252 mounted on one side of the bracket 210 and having a shaft fixedly connected to the gear 251. The toothed belt 260 is meshed with the gear 251. When lifting a tree in a horizontal state, the two sides of the driving member 250 are The toothed belts 260 are of equal length to ensure the stability of the lifting frame 110. When the tree is lifted in a horizontal state, the driving member 250 is started to drive the toothed belt 260 to rotate. At this time, the toothed belt 260 on one side is shortened, and the toothed belt 260 on the other side is extended, driving the sliding frame 160 to rotate. The rotation of the sliding frame 160 drives the lifting frame 110 to rotate, that is, drives the tree fixed on the lifting frame 110 to rotate, and transforms the tree from a horizontal state to a vertical state, so that the tree can be directly placed in the tree hole in a vertical posture later.

[0039] Example 2. A method for hoisting trees for garden engineering, comprising: One end of the hoisting frame strap is inserted into the first slot of the first clamping block, and after the strap is passed around the appropriate position of the tree, the other end of the strap is inserted into the second slot of the tightening member; The electric telescopic rod of the tightening member is started, and the electric telescopic rod drives the second clamping block to move upward, so that the binding belt is gradually tightened until the tree is firmly fixed on the lifting frame; The first motor is started, the first motor drives the roller to rotate, the roller drives the transmission belt to move, and the transmission belt drives the sliding frame to move in the sliding groove of the lifting frame; Starting the lifting frame, which slowly lifts the tree off the ground, and when the tree is lifted to a suitable position, starting the second motor; The second motor drives the gear of the driving member to rotate, and the gear drives the toothed belt to rotate, the toothed belt on one side is shortened, and the toothed belt on the other side is extended, so that the sliding frame rotates around the connecting seat, thereby driving the lifting frame and the tree fixed on the lifting frame to change from a horizontal state to a vertical state; Start the electric telescopic rod of the tightening member, loosen the strap, remove the strap from the first clamping block and the second clamping block, and complete the tree unloading.

[0040] Specifically, The working process of the present invention is as follows: when in use, the hoisting frame 110 is moved to the top of the tree, one end of the strap 150 is inserted into the first slot 121 on the first block 120, and the other end passes through the tree and is inserted into the second slot 1311 of the second block 131, and the electric telescopic rod 132 is started, the electric telescopic rod 132 is started, and the second block 131 is moved upward, and the second block 131 is moved upward, and the strap 150 is tightened, so that the tree and the hoisting frame 110 are fixed together, and the crane can start lifting at this time; During the lifting process, since one side of the tree is heavier and the other side is lighter, the entire lifting frame 110 is in a tilted state. At this time, the horizontal sensor 220 detects the tilt angle and starts the first motor 180. The first motor 180 starts to drive the roller 170 on one side to rotate. The rotation of the roller 170 drives the transmission belt 190 to rotate. The rotation of the transmission belt 190 drives the sliding frame 160 to move on the lifting frame 110. The position of the sliding frame 160 is adjusted to place the center of gravity of the tree at the center point of the sliding frame 160 on the same vertical line. As the sliding frame 160 moves, the tilt angle monitored by the horizontal sensor 220 becomes smaller and smaller. When it reaches a horizontal state, the center of gravity of the tree at the center point of the sliding frame 160 is on the same vertical line. The tree is lifted in a horizontal state and moved to the tree hole position. The second motor 252 is started, and the second motor 252 starts to drive the gear 251 to rotate. The rotation of the gear 251 drives the toothed belt 260 to rotate. At this time, the toothed belt 260 on one side is shortened, and the toothed belt 260 on the other side is extended, driving the sliding frame 160 to rotate. The rotation of the sliding frame 160 drives the lifting frame 110 to rotate, that is, drives the tree fixed on the lifting frame 110 to rotate, and changes the tree from a horizontal state to a vertical state. After that, the tree can be vertically placed in the tree hole. After completion, the electric telescopic rod 132 retracts, driving the second clamping block 131 to retract. At this time, one end of the binding belt 150 is removed from the second clamping block 131, and the lock between the fixing frame 171 and the tree can be released, and the next lifting can be carried out.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
