Description

Technical Field

[0001] This utility model belongs to the field of tree identification technology, specifically relating to a novel tree growth cone. Background Technology

[0002] A novel tree growth cone is a tool for drilling core material from trees. The obtained core material samples help determine the tree's age and health, especially for ancient and famous trees, where studying the core material samples is a crucial means of understanding whether the tree is growing well. Currently, existing novel tree growth cones mainly consist of a hollow tubular sampler and a handle. The sampler's front end is a drill bit structure, and the handle is located at the rear end, perpendicular to the sampler. During operation, the handle is rotated to gradually drill the sampler into the trunk. This manually operated tool is relatively easy to use for trees with a diameter at breast height (DBH) of less than 40cm. However, most ancient and famous trees are old, with thick trunks and large DBHs, many exceeding 100cm, requiring the use of longer samplers. Longer samplers are difficult to operate; on the one hand, the drill bit is difficult to screw into, and on the other hand, they are very prone to tilting, leading to inaccurate core material sampling and affecting subsequent research. Furthermore, the entire process requires manual operation, and sampling can take more than half an hour. If sampling fails, repeated attempts may damage the ancient tree. Therefore, it is essential to develop a new type of tree growth cone that is suitable for deep sampling, can be operated automatically, is not prone to tilting, has high stability, and provides accurate sampling.

The front end of the mounting frame 1 is provided with a guide sleeve 15, and the front end of the drill 5 passes through the guide sleeve 15.

[0019] The working principle and process of this utility model are as follows: The device is placed on one side of a tree trunk, with the support frame 12 supporting it at a suitable position on the ground; the frame 1 and drill 5 are installed facing the location on the tree trunk where the core is to be extracted; the telescopic rod 10 is extended to a 45-degree angle, and the lengths of the upper and lower telescopic rods 10 are adjusted to allow the support feet 11 to rest against the tree trunk, enhancing the stability of the device; a drill 5 of the required length is selected, with the end of the drill 5 clamped in the chuck 14, and the front end of the drill 5 passing through the guide sleeve 15 to enhance stability; before drilling, the lead screw motor 6 is started, which drives the lead screw slider 7 to move forward along the slide rail 2. During the movement... Push the slide block 3, drill drive motor 4, and drill 5 forward. After the drill bit at the front end of drill 5 contacts the tree trunk, it stops moving. Infrared rangefinder 8 measures the distance between drill drive motor 4 and infrared rangefinder 8. First, reset the distance parameter to zero. Start drill drive motor 4 and lead screw motor 6. Drill drive motor 4 drives drill 5 to slowly rotate and drill into the tree trunk. Lead screw motor 6 assists in pushing drill 5 forward. At this time, the distance measured by infrared rangefinder 8 (the distance drill drive motor 4 moves forward) is the depth to which drill 5 enters the tree trunk. After reaching the required depth, all motors stop. Before taking the core material sample, first open the chuck 14 and separate the drill 5; move this device away from the tree trunk; use a commonly used matching core extractor in this field, such as the core extractor that comes with the Haglof new tree growth cone drill, to insert it into the drill 5 from the tail end; carefully take out the core material sample and put it into a special transparent sample tube for preservation. When removing the drill bit 5 stuck in the tree trunk, the chuck 14 of this device can be reconnected to the tail end of the drill bit 5, the drill bit drive motor 4 can be reversed, and at the same time the lead screw motor 6 reverses to drive the slide block 3 to move backward, and the drill bit 5 gradually exits from the tree trunk.
