Description

Technical Field

[0001] This utility model relates to the field of tree bud carving technology, specifically a tree bud carving knife to prevent damage to fruit trees. Background Technology

[0002] The core principle of bud notching is to use a bud notching knife to make horizontal cuts from the bark to the xylem at specific locations on the bud. Notching before the bud promotes germination, while notching after the bud inhibits growth, thereby directionally regulating the distribution of branches.

[0003] Chinese Patent CN220441393U discloses an automatic bud-marking device for fruit trees, belonging to the field of bud-marking technology. It includes a handle and a hollow protective shell disposed on one side of the handle. A rotating assembly is installed inside the hollow protective shell. The top side of a movable plate is connected to a first connecting plate, and a bud-marking knife is disposed at the bottom of the first connecting plate. The rotating assembly includes a drive motor and a rotating shaft disposed at the output end of the drive motor. One side of the drive motor is connected to the inner wall of the hollow protective shell, and the end of the rotating shaft away from the drive motor is connected to a first gear. This device uses the rotating assembly to cause the first gear to move the movable plate downwards, thereby enabling the bud-marking knife to mark the buds on the fruit tree branches.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: when the diameter of the tree changes, it is necessary to frequently rotate the threaded rod to drive the limit plate to adjust in order to make the buds at the corresponding depth, which is not convenient and quick to use and reduces the efficiency of bud making.

[0018] Example 1

[0019] like Figures 1 to 4 As shown, the tree bud-cutting knife for preventing damage to fruit trees proposed in this utility model includes a housing 1, an arc-shaped blade 201, a lower abutment seat 203, an adjustment mechanism, an upper abutment seat 4, and a depth adjustment assembly. A handle 103 is installed at the bottom of the housing 1, and a lifting mechanism is installed inside the housing 1. The arc-shaped blade 201 is adjusted by sliding along the height direction of the housing 1 driven by the lifting mechanism. The lower abutment seat 203 is installed at the bottom of the side wall of the housing 1 and is located below the arc-shaped blade 201. The adjustment mechanism is adjustable and installed inside the housing 1. The upper abutment seat 4 is adjusted by sliding along the height direction of the housing 1, moving closer to or away from the lower abutment seat 203. The end of the upper abutment seat 4 that is away from the adjustment mechanism is adjusted. A third guide port 402 is provided, and the arc-shaped blade 201 is slidably inserted into the third guide port 402. Both the upper abutment seat 4 and the lower abutment seat 203 are provided with arc-shaped parts 401. The depth adjustment component consists of a lifting seat 5, a limiting seat 501 installed on the lifting seat 5, and a slide rod 502 installed on the side of the lifting seat 5. The lifting seat 5 is driven by an adjustment mechanism to slide closer to or further away from the upper abutment seat 4 along the height direction of the housing 1. A touch switch corresponding to the arc-shaped blade 201 is provided at the top of the limiting seat 501. A second guide port 102 is provided on the side wall of the housing 1. The slide rod 502 slides and passes through the second guide port 102. A scale corresponding to the slide rod 502 is provided on the housing 1.

[0020] Furthermore, the adjustment mechanism consists of a sliding tube 3 that is elastically connected to the inner cavity of the housing 1 and a second threaded rod 303 that is rotatably connected to the inner wall of the sliding tube 3. The bottom end of the sliding tube 3 extends to the outside of the inner cavity of the housing 1 and is slidably connected to the side wall of the handle 103. A guide groove 104 is provided on the side wall of the handle 103. A slide seat 302 is installed at the bottom end of the sliding tube 3 and is slidably connected to the guide groove 104. When the sliding tube 3 slides outward along the housing 1 to a suitable position, the operator needs to hold the part of the sliding tube 3 that is exposed outside the housing 1 and the handle 103. The setting of the slide seat 302 can improve the stability of the sliding tube 3 and avoid bending due to excessive force. The bottom end of the second threaded rod 303 extends to the outside of the bottom end of the sliding tube 3 and is equipped with a rotating handle. The top end of the second threaded rod 303 extends to the outside of the top end of the sliding tube 3 and is rotatably connected to the upper abutment seat 4.

[0021] Furthermore, a first guide opening 101 is provided on one side wall of the housing 1. The tool holder 2 and the upper abutment seat 4 are slidably connected to the first guide opening 101. The first guide opening 101 facilitates the guidance of the movement direction of the tool holder 2 and the upper abutment seat 4.

[0022] Furthermore, the sliding tube 3 is designed as a square tube, and a spring 301 is fitted on the outer circumference of the sliding tube 3. One end of the spring 301 is connected to the outer wall of the sliding tube 3, and the other end of the spring 301 is connected to the bottom end of the inner cavity of the housing 1. The sliding tube 3 is slidably connected to the housing 1. The shape of the sliding tube 3 allows it to move up and down along the housing 1 for adjustment, without interfering with the second threaded rod 303 rotating and adjusting along the inner wall of the sliding tube 3.

[0023] Furthermore, the lifting seat 5 is threadedly connected to the second threaded rod 303. The lifting seat 5 has a clearance opening with a diameter larger than that of the first threaded rod 202. The first threaded rod 202 passes through the clearance opening to prevent the lifting mechanism from interfering with the lifting seat 5 when it starts.

[0024] In this embodiment, firstly, the second threaded rod 303 is rotated to drive the lifting seat 5 and the sliding rod 502 to move up or down along the second guide opening 102 to adjust to a suitable position. The longer the distance between the top touch switch of the limiting seat 501 and the arc-shaped blade 201, the deeper the arc-shaped blade 201 can cut the bud on the tree; the shorter the distance between the top touch switch of the limiting seat 501 and the arc-shaped blade 201, the shallower the arc-shaped blade 201 can cut the bud on the tree. The limiting seat 501 is adjusted adaptively according to the required bud cutting depth. Holding the handle 103, the arc-shaped part 401 on the lower abutment seat 203 is brought into contact with a point on the outer periphery of the tree. The sliding tube 3 is slid along the housing 1, which compresses the spring 301. This causes the sliding tube 3 and the second threaded rod 303 to drive the upper abutment seat 4 to slide along the first guide opening 101 until the arc-shaped part 401 on the upper abutment seat 4 is brought into contact with a point on the outer periphery of the tree. At this time, the operator holds the sliding tube 3. The upper part of the device and the handle 103, which are exposed outside the housing 1, are used to quickly limit the upper abutment seat 4 relative to the lower abutment seat 203. The lifting mechanism is activated by the controller to drive the arc blade 201 to slide along the housing 1, so that the arc blade 201 slides into the third guide port 402 until the side end of the arc blade 201 contacts the top of the limit seat 501. The lifting mechanism is then immediately stopped by the controller. At this time, the arc blade 201 has completed the bud notching of the tree. The bud notching can be performed on trees of different diameters by adjusting the lifting mechanism. At the same time, the same bud notching depth does not need to be frequently adjusted according to the size of the tree, which improves the bud notching efficiency. The upper abutment seat 4 and the lower abutment seat 203 can stably connect this device to the bud notching position on the tree and can also guide the arc blade 201 to improve the bud notching accuracy. When it is necessary to change the bud notching depth, it is only necessary to rotate the second threaded rod 303 to adjust the limit seat 501.

[0025] Example 2

[0026] like Figure 2 and Figure 4 As shown, the tree bud-cutting knife for preventing damage to fruit trees proposed in this utility model, compared with Embodiment 1, has a lifting mechanism consisting of a motor installed in the inner cavity of the housing 1, a first threaded rod 202 that is drivenly connected to the output end of the motor, and a knife holder 2 that is threadedly connected to the first threaded rod 202. The top end of the first threaded rod 202 is rotatably connected to the housing 1, and the arc-shaped knife 201 is installed on the knife holder 2.

[0027] It should be noted that a receiving cavity is provided below the mounting cavity of housing 1. The receiving cavity is provided with a power supply mechanism for supplying power to the motor and the touch switch. The power supply mechanism includes a power input module, an energy storage module, a motor power supply switching module, a safety and protection module, etc. This is existing technology, and those skilled in the art can clearly know how to set it up and which components to select for assembly, so it will not be described in detail here.

[0028] In this embodiment, the controller starts the motor to drive the first threaded rod 202 to rotate. Under the guidance of the first guide port 101, the cutter holder 2 moves up or down along the first threaded rod 202 to adjust, thereby driving the arc-shaped cutter 201 to adjust up or down to adapt to trees of different diameters for bud carving. This has a wide range of applications. When the end of the cutter holder 2 away from the arc-shaped cutter 201 contacts the touch switch at the top of the limit seat 501, the controller immediately stops the motor, thereby preventing the arc-shaped cutter 201 from continuing to carve deeper buds into the tree and reducing damage to the tree.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
