Abstract
Description
Technical Field
[0001] The utility model relates to a bark cutting device with adjustable incision depth. Background Art
[0002] In order to prevent the larvae of the pest scale insect from climbing up trees, it is necessary to cut off the bark around the trunk to form a circular incision, and then wrap plastic film or tape around the incision.
[0003] However, when cutting bark, you can't completely remove the entire bark; you can only remove the surface layer (i.e., scrape off the old, rough bark). Otherwise, the tree will not be able to effectively transport nutrients and will die. Furthermore, the bark thickness of different trees varies, so the incision depth needs to be adjusted for different tree species and trunk diameters.
[0004] Some users currently use a cutting tool attached to the chain drive of their chainsaws, which then rotates to drive the cutting tool. However, this method requires additional modification to the chainsaw, making it inconvenient to cut the bark. Furthermore, the depth of the cut is manually controlled by the operator, resulting in inconsistent cut depths and the possibility of completely removing the bark. Utility Model Content
[0005] The utility model aims to provide an adjustable bark cutting device which can adjust the incision depth according to different trees when cutting bark, thereby ensuring that the incision depth for the same tree is basically consistent, is easy to use, and has a smooth incision.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The rotating shaft 32, which is coaxial with the cover 33, is rotatably arranged on the concave side of the cover 33. One end of the rotating shaft 32 is connected to a power device 1 for driving its rotation, and the other end of the rotating shaft 32 is connected to a coaxial tool 34 for cutting bark. The device also includes a cutting depth adjustment device 4 including an interference member 40. Interference members 40 that can move in a tangential direction of the cover relative to the cover 33 are provided at both ends of the circumference of the cover 33. When the tool 34 cuts the bark, the interference members 40 on both sides of the tool 34 contact the trunk, and the distance between the cover 33 and the tool 34 in the radial direction relative to the interference member 40 and the trunk is adjusted, thereby changing the cutting depth of the bark by the tool 34.
[0008] In the above-mentioned adjustable bark cutting device, the power device 1 is a motor, the motor housing is fixed to one end of the cover 33, and the motor output shaft is connected to one end of the rotating shaft 32.
[0009] The above-mentioned adjustable bark cutting device further includes a battery for supplying power to the motor; the battery is electrically connected to the motor via a flexible wire.
[0010] The above-mentioned adjustable bark cutting device also includes a handle rod 36 and a hollow handle 31. The hollow handle 31, which is coaxial with the cover 33, is fixed to one end of the cover 33. The motor housing is fixedly connected to the hollow handle 31. The motor output shaft passing through the hollow handle 31 is connected to the rotating shaft 32. The handle rod 36 is fixed on the convex side of the cover 33.
[0011] In the above-mentioned adjustable bark cutting device, a motor control knob connected to a motor controller is provided on the outer periphery of the hollow handle 31 or on the motor housing. The motor control knob is rotated to change the output speed and torque of the motor.
[0012] In the above-mentioned adjustable bark cutting device, the abutting member 40 is a screw 42; screw seats 41 are provided at both ends of the circumference of the cover 33, and the screws 42 connected to each screw seat 41 by a thread are perpendicular to the circumferential axis of the cover 33; when the tool 34 cuts the bark, the ends of the screws 42 on both sides of the tool 34 abut on the trunk, and the screws 42 are rotated relative to the screw seats 41 to adjust the distance between the cover 33 and the tool 34 in the radial direction relative to the trunk, thereby changing the depth of the cut made by the tool 34 on the bark.
[0013] In the above-mentioned adjustable bark cutting device, the interference component 40 is a interference rod 43; two screw seats 41 are provided at each end of the cover 33 in the circumferential direction, and the two interference rods 43 are located on both sides of the tool 34 and are parallel to the axis of the tool 34. Each interference rod 43 is connected to the two screws 42 located on the same side of the tool 34 by a rotational width; when the tool 34 cuts the bark, the interference rods 43 on both sides of the tool 34 are in contact with the trunk, and the screw 42 is rotated relative to the screw seat 41 to adjust the distance between the cover 33 and the tool 34 in the radial direction relative to the trunk, thereby changing the depth of the cut made by the tool 34 on the bark.
[0014] In the above-mentioned adjustable bark cutting device, the cutter is a spiral cutter having a spiral blade on the outer periphery of the cutter body, or the cutter is a straight cutter having a linear blade on the outer periphery of the cutter body.
[0015] Beneficial effects of the utility model:
[0016] The present invention has an incision depth adjustment device 4. When in use, the abutment members 40 on both sides of the cutter 34 abut against the tree trunk. The abutment members 40 can move relative to the housing 33 in the tangential direction of the housing. This can adjust the radial distance between the housing 33 and the cutter 34 relative to the abutment members 40 and the tree trunk, thereby changing the incision depth of the cutter 34 on the bark.
[0017] When the abutting member 40 is a screw, the ends of the two screws 42 on either side of the cutter 34 abut against the tree trunk, and the screws 42 are rotated relative to the screw base 41 to adjust the radial distance of the cutter 34 from the tree trunk, thereby changing the depth of the cut made by the cutter 34 on the bark. When the abutting member 40 is a rod, the two abutting rods on either side of the cutter 34 abut against the tree trunk, and the screws 42 are rotated relative to the screw base 41 to adjust the radial distance of the cutter 34 from the tree trunk, thereby changing the depth of the cut made by the cutter 34 on the bark.
[0018] The power unit adopts an electric motor, and its motor output shaft is directly connected to the rotating shaft, which simplifies the structure, makes the whole machine light and easy to operate.
[0019] The motor can be directly connected to the power grid or powered by a battery. When powered by a battery, the battery and the motor are separated and connected by a flexible wire, which facilitates the mobile operation of the adjustable bark cutting device.
[0020] There are a handle bar and a hollow handle on the cover. The operator holds the handle bar and the hollow handle with both hands respectively, and the operation is efficient and fast. The motor control knob at the hollow handle can be turned to adjust the motor speed, etc.
[0021] Using a high-speed rotating tool to cut the bark to make a smooth cut, and then wrapping a plastic film or tape of corresponding width around the circular cut of the bark can effectively prevent the larvae of the scale insects from climbing up the tree trunk.
