Description

Technical Field

[0001] The utility model relates to the field of pruning and trimming, and in particular to a drone tree barrier cutting device suitable for multiple tree species. Background Art

[0002] In urban greening construction, most of the trees planted are dwarf trees, such as camphor trees, ginkgo trees, willow trees, etc. As the trees grow, their branches will spread outward and grow onto the road, occupying road space, blocking the road, interfering with the driver's vision, and affecting driving safety. Therefore, the trees need to be pruned and cleaned regularly.

[0003] The commonly used method is to manually saw off the branches while sitting on a lift, which is quite inconvenient due to the high-altitude operation. Alternatively, the operator manually holds a long support pole and places a saw blade on the support pole to saw off the branches, which is very inconvenient in the operation of cutting the branches.

[0004] The Chinese patent with publication number CN 114557207 A discloses a drone tree barrier pruning device with an automatic separation function, which uses a drone with a support rod and a cutting device to complete the pruning of branches. However, due to the support rod and the cutting device, when cutting branches, the drone needs to carry the cutting device and hover to complete the cutting, which has strict operation requirements. Once there is wind, the drone will be unstable in hovering in the air, resulting in the drone being unable to fly and unable to complete the cutting. In addition, the length of the support rod is relatively large, and the center of gravity is far away from the main body of the drone, which will also make the drone difficult to control when flying. Utility Model Content

[0005] The purpose of the utility model is to provide a drone tree barrier cutting device suitable for multiple tree species to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a drone tree barrier cutting device applicable to multiple tree species, comprising a drone and a body fixedly connected to the drone, wherein the body is used to place branches;

[0007] A cutting part is rotatably mounted on the main body, and a tightening component is also arranged on the side of the main body away from the cutting part. The tightening component provides pressure to the cutting part on the branches to achieve cutting of the branches in the main body.

[0008] Preferably, the cutting part includes a motor 1 and a saw blade fixedly mounted on the body, and the output end of the motor 1 is fixedly connected to the saw blade for rotating the saw blade.

[0009] Preferably, the tightening component includes a plurality of motors 2, and the output end of the motor 2 is connected to a tightening wire. When the motor 2 rotates, it can tighten the tightening wire and press the branch toward the saw blade.

[0010] Preferably, both ends of the tightening line are fixedly connected to a motor 2 respectively.

[0011] Preferably, brackets are fixedly mounted on both sides of the body so that the body can be placed stably.

[0012] Preferably, a wire groove is opened on the inner side of the body, and the tightening wire is placed in the wire groove.

[0013] Preferably, a guide portion protruding outward is provided at the opening of the body.

[0014] Preferably, the section of the tightening wire in contact with the wood is a cutting wire, and the cutting wire is provided with uneven convex points. The second motor can slide the cutting wire back and forth on the surface of the wood to achieve cutting of the wood.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] As shown in FIG. 1 , this embodiment provides a drone tree barrier cutting device applicable to multiple tree species, including a drone 1 and a body 2, wherein the body 2 is fixedly mounted with the shell 1 of the drone 1, and the drone 1 can fly with the body 2. Figure 1-2 As shown, the body 2 is a pear-shaped annular structure, the lower diameter of the body 2 is larger than the upper diameter, when cutting branches or tree barriers, the branches extend from the lower part of the body 2 into the inside of the body 2, and branches of different tree species and different thicknesses can be cut. Brackets 3 are also fixedly installed on both sides of the body 2, and the brackets 3 support the body 2 so that the body 2 can be placed on the ground relatively stably.

[0027] A mounting frame is fixedly installed on the inner side of the upper part of the body 2, and a motor 5 is fixedly installed on the mounting frame. A saw blade 6 is fixedly installed on the output end of the motor 5. The motor 5 is used to rotate the saw blade 6 and provide power to the saw blade 6. Two parallel wire grooves 8 are provided on the inner side wall of the body 2. A tightening wire 9 is placed inside each of the two wire grooves 8. The two tightening wires 9 are also arranged in parallel. Four motors 2 4 are also fixedly installed on the upper end of the body 2. The two ends of the tightening wire 9 are each connected to an output shaft of a motor 2 4. The motor 2 4 provides tightening power to the tightening wire 9.

[0028] like Figure 5 As shown by the middle arrow, when the two motors 4 rotate in opposite directions, the tightening wire 9 is wound around the two motor shafts, and the tightening wire 9 is tightened inside the body 2, providing an upward thrust to the saw blade 6 for the branches inside the body 2, pressing the branches toward the saw blade 6. Under the pressure of the tightening wire 9, the saw blade 6 can cut the branches until the branches are cut off. When using the saw blade for cutting, the diameter of the branches to be cut is smaller than the diameter of the saw blade 6, and the saw blade 6 can directly cut the branches when cutting.

[0029] If the diameter of the branch encountered is larger than the diameter of the saw blade 6, when cutting, if the saw blade 6 is used for cutting, the branch will not be completely cut off, and there will still be a connection. Therefore, in a further embodiment, the part where the tightening wire 9 contacts the wood is the cutting wire 10, and the cutting wire 10 is a diamond wire saw blade or a wire saw blade. The cutting wire 10 is provided with uneven convex points, and the motor 24 can drive the cutting wire 10 to slide back and forth on the wood surface to achieve cutting of the wood. Figure 6 As shown by the arrow a in the middle, when cutting the wood strips, when the two motors 24 on the tightening line 9 rotate synchronously clockwise, the motor 24 on the left side rewinds the line, and the motor on the right side releases the line, and the cutting line 10 will follow the Figure 6 When the two motors 4 rotate synchronously in opposite directions, the cutting line 10 moves in the opposite direction of the arrow b on the wood surface, so that the cutting line 10 can move back and forth and cut the wood.

[0030] In this embodiment, a guide portion 7 protruding outward is provided at the opening of the body 2, and the opening diameter of the guide portion 7 is larger than the diameter of the body 2. When cutting branches, the guide portion 7 has a guiding effect on the branches, so that the branches can be better placed inside the body 2. It should be noted that when the body 2 is placed outside the branches, the small branches and leaves of the branches need to be removed to avoid interference with the body 2.

[0031] Although 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 may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
