Description

Technical Field

[0001] This utility model belongs to the field of wood processing technology, specifically relating to a tree peeling device. Background Technology

[0002] In the forestry and timber processing industry, tree bark removal is a key pretreatment process that directly affects the efficiency of subsequent timber processing and the quality of finished products. Currently, traditional bark removal methods mainly rely on manual labor using tools such as axes and scrapers to peel off the bark layer by layer. This is not only labor-intensive and inefficient, but also prone to damaging the xylem due to improper operation.

[0003] While existing mechanical equipment has partially achieved mechanized operation, it suffers from insufficient coordination between the cutting and scraping processes. Current technologies often employ a separate design, where the cutting and scraping mechanisms operate independently. This design complicates the operation process, requiring the cutting and scraping actions to be completed step by step, resulting in low efficiency and certain limitations in its use. Utility Model Content

[0004] The purpose of this invention is to provide a tree bark removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tree bark removal device, comprising:

[0007] Two annular frames are arranged symmetrically at the top and bottom. Each of the two annular frames is composed of two semi-circular frames. One end of the two semi-circular frames constituting the annular frame is rotatably connected, and the other end is detachably connected by a locking mechanism. The two semi-circular frames that are opposite each other at the top and bottom are fixedly connected by a connecting rod.

[0008] A peeling structure is set between two annular frames. The peeling structure includes a movable plate with a pre-drilled hole inside. A scraper is rotatably mounted inside the pre-drilled hole via a torsion spring. The tip of the scraper extends towards the inside of the annular frame. A sliding plate is slidably mounted on one side of the movable plate. A retractable cutting blade is provided inside the sliding plate, and the tip of the cutting blade faces towards the inside of the annular frame.

[0009] Preferably, both ends of the cutting blade extend to the outside of the sliding plate, one end of which is a cutting tip, and the other end of the cutting blade is provided with a pressing handle. A spring is fixedly installed between the pressing handle and the sliding plate, and a push-pull handle is fixedly installed on the outer surface of the moving plate.

[0010] Preferably, the interior of the semi-circular frame is provided with a sliding groove, and the top and bottom of the movable plate are both located inside the sliding groove and are slidably connected to the sliding groove.

[0011] Preferably, the locking mechanism includes a latch fixed to the end of one of the semicircular frames and an L-shaped locking bar rotatably connected to the end of the other semicircular frame, wherein the L-shaped locking bar engages with the latch.

[0012] Preferably, a plurality of elastic blocks are evenly distributed on the inner side of the semi-circular frame, and the elastic blocks are made of rubber or silicone.

[0013] Preferably, the two ends of the connecting rod are fixed to the upper and lower corresponding semi-circular frames by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By integrating the cutting blade and scraper into the moving plate, the cutting blade is controlled to extend and retract by pressing the handle and spring, and accurately cuts into the bark. The scraper is pressed against the surface of the trunk by the torsion spring and automatically scrapes off the bark when the moving plate slides around. The two work together to significantly improve the bark peeling efficiency.

[0016] (2) By setting push-pull handles, it is easy for operators to control the direction of movement of the moving plate, reducing manpower consumption. The lock and L-shaped lock bar enable quick opening and closing, simplifying the installation and disassembly process and reducing operational risks. The elastic blocks are evenly distributed on the inner side of the frame, which not only provide buffer protection for the tree trunk surface, but also increase friction to prevent the device from slipping.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, a tree peeling device includes two annular frames arranged symmetrically at the top and bottom, a connecting rod 2, and a peeling structure;

[0025] Each ring frame consists of two semi-circular frames 1. One end of the two semi-circular frames 1 is rotatably connected by a pivot (not marked), and the other end is detachably connected by a locking mechanism. The locking mechanism includes a latch 12 fixed to the end of one of the semi-circular frames and an L-shaped locking bar 13 rotatably connected to the end of the other semi-circular frame. The end of the L-shaped locking bar 13 is provided with an arc-shaped limiting boss. When the locking bar is rotated to engage with the latch 12, the boss abuts against the edge of the semi-circular frame 1, limiting the rotation angle to 90°, ensuring that there is no risk of springback after locking.

[0026] The rotating connection end of the semi-circular frame 1 adopts a stainless steel pin, and the two ends of the pin are fixed by cotter pins. A copper-based self-lubricating bearing is installed on the contact surface between the pin and the frame to reduce wear.

[0027] The inner wall of the latch 12 is machined with serrated patterns, which engage with the L-shaped locking bar 13. It works with the spring steel ball (with built-in pressure of 0.5N) to achieve self-locking, and requires an external force of more than 5N to unlock.

[0028] During operation, after the two semi-circular frames 1 are closed around the tree trunk, rotate the L-shaped locking bar 13 to make it lock into the buckle 12 to achieve quick locking;

[0029] The two corresponding semicircular frames 1 are fixed together by a connecting rod 2, and the two ends of the connecting rod 2 are connected to the reserved holes of the semicircular frames 1 by bolts;

[0030] The bark removal structure includes a movable plate 3. The top and bottom of the movable plate 3 are embedded in the groove 11 inside the semi-circular frame 1 and can slide along the groove 11. The movable plate 3 has a reserved hole 4 inside. A scraper 5 is installed in the hole by a torsion spring. The tip of the scraper 5 faces the inside of the annular frame. The elasticity of the torsion spring is used to stick to the surface of the tree trunk to remove the bark.

[0031] The slide 11 has a T-shaped cross section, and the inner wall of the slide is coated with polytetrafluoroethylene to reduce the coefficient of friction. The top and bottom of the moving plate 3 are equipped with matching T-shaped sliders, and the gap between the slider and the slide is controlled within 0.5mm to make it slide smoothly and without shaking.

[0032] A sliding plate 6 is slidably connected to one side of the movable plate 3. A retractable cutting blade 7 is provided inside the sliding plate 6. Both ends of the cutting blade 7 extend to the outside of the sliding plate. One end is a sharp cutting tip, and the other end is fixed with a pressing handle 8. A spring 9 is provided between the pressing handle 8 and the sliding plate 6. When not in operation, the cutting blade 7 is completely retracted into the sliding plate 6 to avoid accidental contact.

[0033] The movable plate 3 has a rectangular guide groove on its side, and the sliding plate 6 has a matching rectangle on its back. Nylon bushings are installed at both ends of the guide rail so that the sliding plate 6 can move in a straight line without deviation.

[0034] When the handle 8 is pressed, the cutting blade 7 extends against the spring resistance and cuts into the bark; after it is released, the spring 9 automatically retracts the blade. The outer side of the moving plate 3 is also fixed with a push-pull handle 10, which makes it easy for the operator to push the moving plate along the slide 11.

[0035] Multiple elastic blocks 14 made of rubber are evenly distributed on the inner side of the semi-circular frame 1. When the elastic blocks 14 come into contact with the tree trunk, they deform, which not only provides cushioning and protection for the tree trunk surface, but also increases the friction between the ring frame and the tree trunk to prevent the device from sliding.

[0036] The elastic block 14 is embedded into the inner side of the semi-circular frame 1 through the dovetail groove and is glued in place. Eight elastic blocks are evenly distributed on the inner side of each semi-circular frame 1 with a spacing of 50mm and are arranged in an alternating manner to avoid stress concentration.

[0037] As can be seen from the above, during use, the two semi-circular frames 1 are closed around the tree trunk and locked by the buckle 12 and L-shaped locking bar 13. Press the handle 8 to make the cutting blade 7 cut into the bark. While pressing, move the sliding plate 6 up and down to make the cutting blade 7 cut the bark. Push the push-pull handle 10 to push the moving plate 3, so that the moving plate 3 moves around the groove 11. The scraper 5 scrapes off the bark under the action of the torsion spring. After the bark is peeled off, release the locking mechanism and remove the device.

[0038] Example 2:

[0039] This embodiment is a further optimization based on Embodiment 1. The tip of the cutting blade 7 is designed with serrations to enhance cutting efficiency.

[0040] The elastic block 14 is replaced with silicone material to improve wear resistance; the rest of the structure and operation are the same as in Example 1.
