Description

Technical Field

[0001] The invention belongs to the field of municipal garden engineering, and in particular relates to a garden tree pruning device and a digital platform maintenance and pruning method. Background Art

[0002] At present, the maintenance and pruning of garden trees are mainly done by saws or pruning shears. The pruning effect is affected by the level of the workers and varies. In addition, the traditional pruning method is to directly cut the trees. The healing time of the cut wound is long, the scars are large after pruning, and the plant growth recovery is slow. Sometimes, unreasonable pruning such as heavy pruning will cause the trees to weaken or even die, resulting in the inability to scientifically manage the maintenance and pruning of urban garden trees.

[0003] Traditional tree maintenance and pruning mainly rely on manual pruning, which often adopts a simple and rough pruning method, resulting in large pruning differences and deviations, which affects the ornamental appearance of urban trees. In addition, due to the wide variety of pruning environments, pruning work has safety hazards. Traditional pruning methods cannot achieve large-scale standardized production, lack a macro-control model, and lack a scientific management macro-pruning method. Summary of the invention

[0004] In order to solve the deficiencies of the prior art, the present invention provides a garden tree pruning device and a digital platform maintenance and pruning method.

[0005] The present invention is achieved through the following technical solutions:

[0006] A garden tree pruning device comprises an electric telescopic rod A, the upper end of which is fixedly connected to the bottom of a supporting box, the supporting box is provided with a groove, one side of the supporting box is integrally connected to a side plate, an electric telescopic push rod is provided on the side plate, a shell is placed in the groove, a U-shaped accommodating cavity is provided in the middle of the shell, an electric telescopic rod B is fixed in the shell, the upper end of the electric telescopic rod B extends out of the shell and is fixedly connected to a cutting ring, when the electric telescopic rod B is fully retracted, the upper end of the electric telescopic rod B is flush with the lowest point of the U-shaped accommodating cavity, the cutting ring is placed in the U-shaped accommodating cavity, the cutting ring comprises two hinged upper and lower semicircular rings, the closed ends of the upper and lower semicircular rings are provided with electromagnetic locks, the closed ends are arranged on a side away from the side plate, a resistance wire is arranged on the inner wall of the cutting ring, the resistance wire is connected to the electric wire in the shell, and the electric wire passes through the outlet hole of the side wall of the shell to connect to a power supply; the electric telescopic rod A, the electric telescopic push rod, the electric telescopic rod B, and the electromagnetic lock are all connected to a PLC controller.

[0007] Preferably, the resistance wire is a nickel-chromium resistance wire.

[0008] Based on the above-mentioned garden tree pruning device, the present invention also includes a garden tree digital platform maintenance and pruning method, comprising the following steps:

[0009] Step 1: Use drone oblique photogrammetry technology to construct a three-dimensional tree model;

[0010] Step 2: Import the tree 3D model into the model software after lightweight processing, simulate pruning the tree 3D model in the model software, and select the best simulated pruning effect to determine the branches to be pruned and the cutting points;

[0011] Step 3: After determining the branches to be pruned and the cutting points, use a ring barking knife to ring the cutting points;

[0012] Step 4: 3-5 months after the ring barking, the garden tree pruning device of the present invention is used to cut the ring barking part of the tree during the dormant period.

[0013] Specifically, when the garden tree pruning device in step 4 is used, the outer shell is first placed into the groove of the support box, the cutting ring is opened, and the wires passing through the wire outlet hole are connected to the power supply on the ground. The PLC controller controls the electric telescopic rod A to extend upward until the cutting ring is sleeved on the branch at the ring-barking position, and then the PLC controller controls the electric telescopic push rod to extend, and the electric telescopic push rod drives the upper semicircular ring to rotate and close with the lower semicircular ring, locks the electromagnetic lock, and then the electric telescopic rod A contracts downward to separate the support box from the outer shell, turns on the power, and at the same time controls the electric telescopic rod B to extend up and down to drive the cutting ring to cut off the branch at the ring-barking position.

[0014] Furthermore, the electric wires are fixed to the trees from bottom to top by a fully automatic cable bundling machine.

[0015] Furthermore, the simulated pruning in step 2 is performed with reference to pruning specifications, and the three-dimensional model of the tree is pruned according to the pruning specifications to perform one or more of dead branches, inner branches, parallel branches, crossing branches, sprouting branches, and sucker branches.

[0016] Furthermore, in the step 4, a wound patch is applied after ring peeling.

[0017] Furthermore, in the step 2, lightweight processing is performed through the SuperMap software platform.

[0018] The present invention has the following beneficial effects:

[0019] (1) Intelligent data collection and pre-simulation of pruning are used to ensure the final pruning effect;

[0020] (2) Higher safety: workers do not have to climb high during the pruning process and can stay away from the pruning area, ensuring personnel safety;

[0021] (3) The cut surface is carbonized, which makes it difficult to leave wounds and does not require disinfection, ensuring that the wounds after pruning heal quickly;

[0022] (4) Pruning adopts a gradual pruning method of first ring barking and then carbonization cutting, which breaks the traditional pruning mode. The damage to the tree after pruning is reduced to the minimum, avoiding the weakening or death of the tree caused by traditional pruning;

[0023] (5) The method of the present invention can be used to prune and shape urban trees on a large scale, thereby improving pruning efficiency and ornamental value. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Specific embodiments of the present invention are given below in conjunction with the accompanying drawings. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of this application belong to the protection scope of the present invention.

[0034] The garden tree pruning device of the present invention comprises an electric telescopic rod A7, the upper end of which is set at the bottom of a support box 6. The support box 6 is provided with a groove 3, one side of the support box 6 is integrally connected to a side plate 8, and a miniature electric telescopic push rod 5 is provided on the side plate 8, and the telescopic direction of the electric telescopic push rod 5 is horizontal. The electric telescopic rod A7 and the electric telescopic push rod 5 are both connected to a PLC controller, and their movements are controlled by the PLC controller.

[0035] A housing 4 is placed in the groove 3 of the tray 6, and a U-shaped accommodating chamber 9 is provided in the middle of the housing 4, and a cutting ring 1 is placed in the U-shaped accommodating chamber 9. An electric telescopic rod B2 is fixed inside the housing 4, and the upper end of the electric telescopic rod B2 extends out of the housing 4 and is fixedly connected to the cutting ring 1. The cutting ring 1 includes two hinged upper semicircular rings 11 and lower semicircular rings 12. In this embodiment, the upper semicircular ring 11 and the lower semicircular ring 12 are connected together by a rotating shaft, and the upper semicircular ring 11 and the lower semicircular ring 12 are closed to form a circular cutting ring 1. When the electric telescopic rod B2 is fully retracted, the upper end of the electric telescopic rod B2 is flush with the lowest point of the U-shaped accommodating chamber 9, and the closed cutting ring 1 can be completely placed in the U-shaped accommodating chamber 9. An electromagnetic lock is provided at the closed end of the upper semicircular ring 11 and the lower semicircular ring 12, and the closed end is located on the side away from the side plate 8. The electric telescopic rod B2 and the electromagnetic lock are also connected to the PLC controller and controlled by the PLC controller. The cutting ring 1 is closed by the electric telescopic push rod 5 extending to push the upper semicircular ring 11 to rotate. When the upper semicircular ring 11 and the lower semicircular ring 12 are closed, an electromagnetic lock further locks the two together.

[0036] A resistance wire is arranged on the inner wall of the cutting ring 1, and the resistance wire is connected to the wire 10 in the shell 4. A wire outlet hole is arranged on the side wall of the shell 4, and the wire 10 in the shell 4 passes through the wire outlet hole to connect to the power supply on the ground, and the power supply can be a battery pack. The resistance wire is energized to realize the cutting of trees, and the resistance wire is preferably a nickel-chromium resistance wire. Resistance wire cutting is a well-known and widely used technology, and its principle and structure are not described here.

[0037] Utilizing the above-mentioned garden tree pruning device, the present invention also includes a garden tree digital platform maintenance and pruning method, comprising the following steps:

[0038] 1. Use oblique photogrammetry technology to construct a 3D tree model

[0039] DJI drones are used to collect image information of the trees to be pruned, and the collected information is transmitted to the 3D modeling software, in which a 3D model of the tree is constructed.

[0040] 2. Determine the cutting point

[0041] The constructed 3D tree model is imported into the SuperMap software platform for lightweight processing and then imported into the model software. The 3D tree model is simulated and pruned in the model software. The model software can select SketchUp design software to simulate the pruning of the tree multiple times, and then select the best simulated pruning effect to determine the final branches and cutting points to be pruned.

[0042] During simulated pruning, refer to the set pruning specifications for pruning, and prune dead branches, inner branches, parallel branches, crossing branches, sprouting branches, and sucker branches of trees according to the pruning specifications.

[0043] Step 3: Ringing

[0044] After determining the branches to be pruned and the cutting points in step 2, use a ring-barking knife to ring the cutting points of the branches to be pruned, and apply a wound patch after ring-barking to promote wound healing.

[0045] Step 4: Cutting

[0046] The girdling part of the tree is cut 3-5 months after the girdling in step 3 and during the dormant period of the tree. In this embodiment, the garden tree pruning device of the present invention is used to cut the girdling part.

[0047] The specific cutting operation process is as follows: the shell 4 of the garden tree pruning device is placed into the groove 3 of the support box 6, the cutting ring 1 is opened, the wire 10 passing through the wire outlet hole is connected to the power supply on the ground, the worker holds the electric telescopic rod A7, and controls the electric telescopic rod A7 to extend upward through the PLC controller, and puts the cutting ring 1 on the branch at the ring-barking position, and then controls the electric telescopic push rod 5 to extend horizontally, and the electric telescopic push rod 5 pushes the upper semicircular ring 11 to rotate and close with the lower semicircular ring 12. After the upper semicircular ring 11 and the lower semicircular ring 12 are closed, the electric telescopic push rod 5 retracts, and the PLC controller controls the electromagnetic lock to lock, and then the electric telescopic rod A7 is retracted downward to make the support box 6 separate from the shell 4, and the cutting ring 1 is hung at the ring-barking position.

[0048] The present invention can cut multiple cutting points at one time. Cutting rings 1 are hung at multiple cutting points. After the cutting rings 1 are hung at the cutting points, the power is turned on, the resistance wire is energized to cut the branches, and the electric telescopic rod B2 is controlled to move up and down to drive the cutting ring 1 to move up and down to cut the branches at the ringing position. After the branches are cut, the power is disconnected, and the PLC controller controls the electric telescopic rod B2 to shrink to be flush with the bottom of the U-shaped accommodating cavity 9. At this time, the cutting ring 1 is completely stored in the U-shaped accommodating cavity 9 of the housing 4, as shown in the attached figure. Figure 5 Workers should stay away from the tree when cutting.

[0049] In order to prevent the housing 4 and the cutting ring 1 from falling directly after the branch is cut and causing damage to the device, the wire 10 connected to the power supply is preferably fixed to the tree from bottom to top before cutting. Preferably, a fully automatic cable bundling machine is used to bundle the wire 10 to the tree trunk or branch, so that when the cutting ring 1 falls, it will not fall directly, but will be suspended in the air by the wire 10.

[0050] The embodiment described above is only one of the more preferred specific implementations of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
