Description

Technical Field

[0001] This utility model belongs to the field of drilling device technology, specifically relating to a drilling device for the restoration of ancient trees. Background Technology

[0002] During the growth and restoration of ancient trees, they are often threatened by pests and diseases. The main period of damage is the larval stage of trunk-boring insects. The larvae first gnaw on the bark, and then enter the xylem to gnaw, causing the tree branches and trunks to become hollow, die, or break and fall. Once the larvae enter the xylem of the tree through their tunnels, they are difficult to track and are highly concealed, making it difficult to find the precise location of the larvae and thus making prevention and control difficult.

[0003] Traditional chemical control methods involve spraying pesticides onto the leaves or trunks of garden plants. While pesticide spraying can address most pests and diseases, it is less effective against borers and suckers. To address this limitation, operators use trunk drilling for injection, which effectively controls borers and suckers. However, common drilling devices are not easy to adjust the drilling depth, leading to holes that are too deep or too shallow. This makes it difficult to drill holes for trees of different sizes, hindering pesticide injection and causing significant inconvenience for users. Utility Model Content

[0004] To overcome the limitations of pesticide spraying for controlling borers and piercing-sucking pests, and the inconvenience of adjusting drilling depth in common drilling devices that hinder pesticide injection, this invention provides a drilling device for ancient tree restoration. This device administers pesticides to trees by drilling holes in the trunk, directly injecting the pesticide into the pest's active area. It is particularly suitable for controlling borers and piercing-sucking pests, improving control effectiveness. The drill bit is available in different lengths to accommodate trees of varying thicknesses, ensuring appropriate drilling depth and facilitating pesticide injection. Timely and effective pest control helps protect the healthy growth of ancient trees, extends their lifespan, and maintains ecological stability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A drilling device for ancient tree restoration mainly includes an electric pistol body, a battery, a micro motor, a handle, a protective shell, a drive shaft, a driven shaft, a drive gear, a driven gear, a drill bit fixing sleeve, and a drill bit.

[0017] This utility model discloses a drilling device for ancient tree restoration. The device mainly includes an electric pistol body 1, a battery 2, a micro motor 3, a handle 4, a protective shell 5, a drive shaft 6, a driven shaft 7, a drive gear 8, a driven gear 9, a drill bit fixing sleeve 10, and a drill bit 11. The electric pistol body 1 has a hollow internal structure. The battery 2 and the micro motor 3 are installed inside the electric pistol body 1. The handle 4 is installed at the bottom of the electric pistol body 1 and has a switch button 41. The protective shell 5 is installed on... The electric pistol body 1 has a handle 51 at the front end and the protective shell 5 at the end. The drive shaft 6 and driven shaft 7 are rotatably installed inside the protective shell 5. The drive gear 8 and driven gear 9 are respectively installed on the drive shaft 6 and driven shaft 7, and the drive gear 8 and driven gear 9 are meshed with each other. The drive shaft 6 is driven by the output end of the micro motor 3. The drill bit fixing sleeve 10 is installed at the front end of the protective shell 5. The driven shaft 7 is driven by the drill bit fixing sleeve 10. The drill bit 11 is installed on the drill bit fixing sleeve 10. The drill bit 11 is provided with different length specifications.

[0018] like Figure 2 , Figure 3 As shown, the effort-saving handle 51 has an effort-saving groove 511 and a silicone anti-slip layer on its surface; the effort-saving groove 511 makes it more comfortable for the operator to hold, and the silicone anti-slip layer on its surface can prevent the device from slipping during operation.

[0019] like Figure 2 As shown, the drill bit 11 adopts a double-helix structure, including a main cutting edge 111, a secondary cutting edge 112, and a drill tip 113. A spiral groove 1121 is formed between the main cutting edge 111 and the secondary cutting edge 112. A nano-ceramic coating is embedded in the spiral groove 1121. The drill tip 113 is installed at the front end of the main cutting edge 111 and the secondary cutting edge 112, and the drill tip 113 is set as a carbide guide head. When the drill tip 113 is aligned with the position to be drilled, pressure is gently applied so that the drill tip 113 gradually drills into the old tree. The double-helix structure of the drill bit 11 and the main cutting edge 111 and the secondary cutting edge 112 can effectively cut wood. The spiral groove 1121 helps to remove sawdust. The nano-ceramic coating can improve the wear resistance and cutting performance of the drill bit 11.

[0020] like Figure 2 , Figure 4 , Figure 5 As shown, a heat dissipation strip groove 12 is provided on the side wall of the electric pistol body 1; during the drilling process, the micro motor 3 inside the electric pistol body 1 will generate heat, and the heat dissipation strip groove 12 helps to dissipate the heat generated by the micro motor 3 and maintain the normal operating temperature of the device.

[0021] Work process:

[0022] The operator selects a suitable drill bit 11 from different lengths and specifications based on the thickness of the ancient tree to be drilled, and installs it on the drill bit fixing sleeve 10. The operator checks the battery 2 inside the electric pistol body 1 to ensure sufficient power; if insufficient, it needs to be charged first. The operator holds the handle 4 with one hand and the effort-saving grip 51 at the end of the protective shell 5 with the other. The effort-saving groove 511 on the effort-saving grip 51 provides a more comfortable grip, and its surface is covered with a silicone anti-slip layer to prevent the device from slipping during operation. The operator presses the switch button 41 on the handle 4. At this time, the battery 2 supplies power to the micro motor 3, which starts running. The output of the micro motor 3 drives the drive shaft 6 to rotate, and the drive gear 8 mounted on the drive shaft 6 rotates accordingly. Since the drive gear 8 and the driven gear 9 are meshed, the driven gear 9 drives the driven shaft 7 to rotate. The driven shaft 7 is connected to the drill bit fixing sleeve 10, thereby driving the drill bit 11 mounted on the drill bit fixing sleeve 10. 1. The high-speed rotation begins. The operator aligns the high-speed rotating drill bit 11 with the location on the ancient tree where a hole needs to be drilled and begins drilling. The drill bit 11 adopts a double-helix structure. The main cutting edge 111 and the secondary cutting edge 112 can efficiently cut the tree. The drill tip 113 is set as a carbide guide head, which allows the drill bit 11 to accurately drill into the tree, improving the drilling accuracy. During the drilling process, the nano-ceramic coating embedded in the spiral groove 1121 can reduce the friction between the drill bit 11 and the tree, improving the service life and drilling efficiency of the drill bit 11. At the same time, the heat dissipation strip groove 12 opened on the side wall of the electric pistol body 1 can effectively dissipate the heat generated by the micro motor 3 during operation, ensuring the normal operation of the device. When the appropriate drilling depth is reached, the operator releases the switch button 41 on the handle 4. The micro motor 3 stops running, and the drill bit 11 also stops rotating. The operator removes the device from the tree, completing the drilling operation. Subsequent work such as injecting medicine and other ancient tree restoration work can then be carried out.

[0023] This device is suitable for ancient trees of all ages and species. It allows for precise drilling to inject restorative solutions and vitality enhancers, accurately delivering these substances into the boreholes to promote the tree's self-repair and growth. Benefits include: 1. Enhancing tree vitality: The injection of restorative solutions and vitality enhancers provides the necessary nutrients and growth factors, improving the tree's vitality and overall health. 2.
