First, the use of tree growth cone
Forestry research often requires sampling and measuring trees. Tree growth cones are a tool for quickly and reliably calculating the age of trees. It can analyze and determine the growth rate of trees, the age of trees, the solidity of tree growth, the pollution of tree growth environment and the migration of nutrients, etc. by drilling the wood core samples without destroying the normal growth of trees. The Haglof growth cone uses Swedish carbon steel to ensure a robust growth cone and fast sampling. Applied to forestry, forest ecology and other fields. It can also be used to measure the degree of deep keratinization of trees, to detect wooden-wood buildings and to identify the age of old trees.
Second, HAGLOF tree growth cone use method
1. Install 1). Unscrew the nut at one end of the blue handle and take out the drill (clam) and core puller (Note: Since there is thread inside the handle, try not to pull out the drill (mouth) Let the drill touch the thread in the handle, which will easily cause scratches on the surface of the drill, affecting the appearance and use)
2). Play the mechanical lock (snap) on the middle of the blue handle. Insert the drill into the lock and secure it with the lock. The assembly diagram is as follows: 2, use
1). After the growth cone is installed, press the drill bit onto the trunk at a 90 degree angle. Turn the handle and drill the drill into the trunk. Do not use too much force and force the handle at the same time. It is important to keep the flat angle when turning the handle to avoid too much effort when drilling. If the trees are hard or the trees are dry, it is recommended to use a power drill to drill a certain depth before using the growth cone to drill into the trunk, which is easier to drill into.
2). When the drill penetrates the trunk approximately 2-4 cm or 0.8-1.5 inches, it is recommended to stop pushing hard instead of simply turning the handle with the open palm until the drill reaches the desired depth. The depth of the hole is usually deep into the center of the trunk. Remember to maintain the verticality of the drill bit throughout the drilling process.
3). When the growth cone is drilled to the required depth, stop turning the handle and insert the core puller from the hole in the back of the drill. (Note: the core groove of the core must be facing up) Insert the core puller into the same depth as the drill. After pushing the core puller into the hole, reverse the handle by half a turn or one turn to break the tree core or loosen the core.
4). After twisting the tree core, carefully remove the core puller, and the core of the core is tightly fixed by the tooth end of the core puller. If possible, it is recommended to insert the tree core after inserting it into the tree. This helps the trees heal themselves and prevents insects from invading sensitive species. After removing the tree core, reverse the growth cone and remove the growth cone from the trunk.
Use the example map:
3, the problem of decay, or dry trunk wood, making the extraction of the core becomes difficult, or become a hindrance to the drilling process. Try changing the location or try another tree if possible. Do not insert the core puller into the drill bit and drill. The core puller should be inserted after the drilling process is completed. It is important to extract the core sample as quickly as possible. Fresh and healthy trees begin to swell instantly, closing small holes in the trunk. If the drill stays in the trunk for too long, the wood inside the drill will also swell, which can cause the drill to rupture or become difficult to remove from the trunk. If there are nails or other metal parts in the tree, or if it is suspected to rot, spoil, or contain dry wood, it is not recommended to use growth cones on this tree. The drill bit should always enter the tree horizontally because the edge of the drill is sharp and it is easy to hit and cut the wood fiber and the annual ring.
4. Maintenance Do not store the tree growth cone in a damp and dirty place. Always clean your drills, especially the drill threads and core pullers, and clean them immediately after use. Use a thin oil (such as sewing machine oil) and wash with a small soft and clean paper towel or rag. Be careful because the threads and core pullers are very sharp! You can use beeswax on the drill bit to protect it as a lubricant (but you know, if you do biological research, beeswax may affect the purity of your sample).
5. Precautions Since all parts of the tree growth cone are produced in Sweden, there is no way to provide after-sales service. Once the growth cone has problems or any parts are damaged, it cannot be guaranteed or can only be replaced. The maintenance cost is very high. For this reason, please check the three parts after receiving the growth cone and check for damage and damage. Please be careful when using the growth cone and take the steps as described in the instructions. Never use brute force in the process of operating the growth cone.
Third, the length of the tree growth cone and the choice of thread style
1. Length selection Since the tree rings are all round and round, it is recommended to select the growth cone according to the diameter of the tree to be sampled. Generally, the growth cone of 1/2 length of the diameter of the measured tree is selected. can. For example, the large diameter of the zui to be measured is 80 cm, and the growth cone with a length of 40 cm can meet the sampling requirements.
2, thread style selection Swedish tree growth cone has two thread styles, two thread and three thread. The two-threaded growth cone is suitable for hard trees and can be turned into 8mm per revolution. The three-thread thread is suitable for softer trees and can be turned into 12mm per revolution. If possible, choose a two-thread thread type that will last longer. How to judge whether the growth cone is imported or not. The first growth cone is a tool, a special tool that is more expensive than other tools. The shape characteristics of the growth cone itself determine that there is not much way to post or engrave the logo or LOGO of the HAGLOF SWEDEN AB company in the growth cone package or the vertebral body itself, but the Swedish tree growth cone is still engraved with some logo. The growth cone is marked with the following figure: All specifications of the tree growth cone (length, thread style and sampling diameter) No. Product specification model 4.35mm/5.15mm Diameter (threaded two-wire/three-wire): CO100 growth cone, length 100mm, Increment Borer 100 mm CO150 growth cone, length 150 mm, Increment Borer 150 mm CO200 growth cone, length 200 mm, Increment Borer 200 mm CO250 growth cone, length 250 mm, Increment Borer 250 mm CO300 growth cone, length 300 mm, Increment Borer 300 mm CO350 growth cone, length 350 mm, Increment Borer 350 mm CO400 growth cone, length 400 mm, Increment Borer 400 mm CO450 growth cone, length 450 mm, Increment Borer 450 mm CO500 growth cone, length 500 mm, Increment Borer 500 mm 5.15 mm diameter (threaded two/three wire) CO600 growth cone, length 600 mm, Increment Borer 600 mm CO700 growth cone, length 700 mm, Increment Borer 700 mm CO800 growth cone, length 800 mm, Increment Borer 800 mm CO1000 growth cone, length 1000 mm, Increment Borer 1000 mm 10 mm diameter (threaded second line) CO300A 300 mm long tree growth cone, inner diameter 10 mm, 2 lines .CO400A400 mm long Tree growth cone, inner diameter 10 mm, 2 lines.
