Description

Technical Field

[0001] This invention relates to the field of forestry tree trunk treatment equipment technology, and more specifically, to a forestry tree trunk treatment device. Background Technology

[0002] In traditional forestry operations, after tree trunks are sawed off, further cleaning work is usually required, such as removing branches and bark, to facilitate transportation and further processing.

[0003] The trunk is columnar with rounded sides. When cutting the side branches of the trunk, using straight-line operation tools such as chainsaws and axes will leave some residue. Multiple operations are required, and traditional trunk processing methods may pose safety hazards, such as operators being injured while processing branches.

[0004] When saw blades driven by hydraulic, pneumatic, or electric motors cut against the resistance of side branches, they transmit a large force to the cylinder or gears, which will cause certain wear and damage to the equipment. In particular, the resistance varies greatly, and long-term use will affect the service life of the power mechanism. Therefore, a tree trunk processing device that can quickly process branches on tree trunks has been designed to improve the overall work efficiency. Summary of the Invention

The second cutting saw tooth bracket is connected to the second cutting saw tooth, and the second cutting saw tooth and the first cutting saw tooth cooperate with each other.

[0008] Another limiting shaft is set in the slot of the U-shaped rod. One end of the U-shaped rod is fixedly connected to the support base. The support base is fixed to the lower side of the other end of the symmetrical arc-shaped bracket. The U-shaped rod is arranged laterally and is connected to the drive assembly.

[0009] The drive assembly includes a lateral moving component connected to the U-shaped rod and the U-shaped moving rod. The two sides of the U-shaped moving rod are rotatably connected to the middle of a crossbar.

The angle between the first diagonal rod and the crossbar is 150 degrees, and the angle between the second diagonal rod and the crossbar is 30 degrees. One end of a first spring is fixedly connected to the end of the crossbar away from the arc-shaped rod, and the other end of the first spring is fixedly connected to one side of the U-shaped moving rod.

[0010] The outer end of the U-shaped rod is fixedly connected to a stop shaft one, the stop shaft one is matched with the inclined rod one, and the inclined rod two is matched with the corresponding limiting shaft.

[0011] As a further limitation of this technical solution, the lateral moving component is an electric push rod, the electric push rod fixes the U-shaped rod, and the telescopic rod end of the electric push rod is fixed to the lower middle part of the U-shaped moving rod.

[0012] As a further limitation of this technical solution, the second cutting saw bracket includes an I-shaped bracket, a fixed rod, a second spring, and symmetrical telescopic rods.

[0031] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described in conjunction with the embodiments.

[0032] A forestry tree trunk processing device includes symmetrically arranged arc-shaped supports 1, on which a cutting module is slidably arranged. The cutting module includes symmetrically arranged arc-shaped rods 7, and the arc-shaped supports 1 are arranged between the symmetrically arranged arc-shaped rods 7. The two ends of the symmetrically arranged arc-shaped rods 7 are respectively fixedly connected to the two ends of the limiting shafts 18. Arc-shaped slide rails are respectively opened on the symmetrically arranged arc-shaped support 1, and the two ends of the limiting shafts 18 are respectively arranged in the arc-shaped slide rails. One end of one arc-shaped rod 7 is fixedly connected to one end of the corresponding arc-shaped support 1 by a spring 8.

[0033] The curved rod 7 is curved to allow it to be launched to the end and avoid the tree trunk.

[0034] One end of the symmetrically arranged arc-shaped bracket 1 is fixedly connected to both ends of the cutting saw tooth 20. A limiting shaft 18 set in the arc-shaped slide rail is fixedly connected to the cutting saw tooth bracket 2. The cutting saw tooth bracket 2 is connected to the cutting saw tooth 24. The cutting saw tooth 24 and the cutting saw tooth 20 cooperate with each other.

[0035] In this embodiment, the arc-shaped bracket 1 is placed on the outer wall of the vertical rod, so that it moves along the outer wall to the branch of the tree trunk. The limiting shaft 18 moves along the arc-shaped slide rail, thereby driving the arc-shaped rod 7 to move. The spring 3 8 undergoes elastic deformation, realizing the cutting module ejecting along the arc-shaped slide rail. The cutting saw tooth 24 can achieve reciprocating motion. When the cutting saw tooth 24 ejects in the direction of the cutting saw tooth 20, it cuts the branch.

[0036] Another limiting shaft 18 is set in the slot of the U-shaped rod 6. One end of the U-shaped rod 6 is fixedly connected to the support base 25. The support base 25 is fixed to the lower side of the other end of the symmetrical arc bracket 1. The U-shaped rod 6 is arranged horizontally and is connected to the drive assembly.

[0037] In this embodiment, another limiting shaft 18 moves along the slot of the U-shaped rod 6, and the driving component can drive the limiting shaft 18 to move.

[0038] The drive assembly includes a lateral moving component connected to the U-shaped rod 6 and the U-shaped moving rod 12. The two sides of the U-shaped moving rod 12 are rotatably connected to the middle of a crossbar 16. One end of the crossbar 16 is fixedly connected to a first diagonal rod 15, and the other end is fixedly connected to a second diagonal rod 17. The angle between the first diagonal rod 15 and the crossbar 16 is 150 degrees, and the angle between the second diagonal rod 17 and the crossbar 16 is 30 degrees. The end of the crossbar 16 facing away from the arc-shaped rod 7 is fixedly connected to one end of a first spring 13, and the other end of the first spring 13 is fixedly connected to one side of the U-shaped moving rod 12.

[0039] In this embodiment, the two arc-shaped rods 7 are respectively fixedly connected to springs 8, and the springs 8 are respectively fixedly connected to the corresponding arc-shaped brackets 1.

[0040] The outer end of the U-shaped rod 6 is fixedly connected to the stop shaft 14, the stop shaft 14 is matched with the inclined rod 15, and the inclined rod 17 is matched with the corresponding limiting shaft 18.

[0041] In this embodiment, the lateral moving component drives the U-shaped moving rod 12 to move, and the U-shaped moving rod 12 drives the horizontal rod 16, the first diagonal rod 15, the second diagonal rod 17 and the first spring 13 to move. The movement of the cutting module is achieved by the cooperation between the first diagonal rod 15 and the first stop shaft 14 and the cooperation between the limiting shaft 18 and the second diagonal rod 17.

[0042] When the second inclined rod 17 moves to abut the limiting shaft 18, it encounters resistance. As the lateral moving assembly continues to move it, the second inclined rod 17, due to the fixed horizontal rod 16, which is rotatably connected to the U-shaped moving rod 12, will move upward under the pushing force, causing the horizontal rod 16 to swing. The first spring 13 undergoes elastic deformation. When the second inclined rod 17 is higher than the limiting shaft 18, under the rebound force of the first spring 13, the second inclined rod 17 swings downward and blocks the limiting shaft 18. At this time, the lateral moving assembly drives the U-shaped moving rod 12 to move in the opposite direction, and then... The cutting module moves, and the cutting module's moving spring 3 8 is stretched until the diagonal rod 15 abuts against the stop shaft 14. When the diagonal rod 15 continues to move in the opposite direction under the action of the lateral moving component, since the horizontal rod 16 rotates and connects to the U-shaped moving rod 12, the angle between the diagonal rod 15 and the horizontal rod 16 is 150 degrees. At this time, the diagonal rod 15 moves downward under the reaction thrust, and the diagonal rod 2 17 moves upward until the diagonal rod 2 17 disengages from the limit shaft 18. At this time, the spring 3 8 rebounds, driving the arc rod 7 to rebound. The arc rod 7 drives the cutting module to be ejected, cutting off the tree branch.

[0043] The lateral moving component is an electric push rod 5, which fixes the U-shaped rod 6. The telescopic end of the electric push rod 5 is fixed to the lower middle part of the U-shaped moving rod 12.

[0044] In this embodiment, the reciprocating movement of the U-shaped moving rod 12 is achieved by the extension and retraction of the telescopic rod of the electric push rod 5, and the ejection movement of the cutting component is achieved by the drive component. When the cutting component is ejected, the drive component does not contact the cutting component, and the power is applied by the rebound force of the spring 8, thereby eliminating wear on the drive component. The use of the drive component is not affected regardless of whether the resistance is large or small.

[0045] The cutting saw tooth bracket includes an I-shaped bracket 10, a fixed rod 21, a second spring 23, and symmetrical telescopic rods 22. The I-shaped bracket 10 is fixedly connected to the limiting shaft 18, which is set inside the arc-shaped slide rail. The I-shaped bracket 10 is a bracket composed of round rods, and its end is set inside the arc-shaped slide rail and matches the arc-shaped slide rail. The limiting shaft 18 matches the arc-shaped slide rail. One end of the I-shaped bracket 10 is fixed to the fixed rod 21. The fixed rod 21 fixes the cutting saw tooth 24 through the second spring 23. The two ends of the fixed rod 21 are respectively fixed to one end of the telescopic rod 22, and the other end of the telescopic rod 22 is fixed to the cutting saw tooth 24.

[0046] In this embodiment, the I-shaped bracket 10 is set inside and matched with the arc-shaped slide rail, which increases the stability of the second cutting saw bracket when it moves. In use, due to the large ejection force of the third spring 8, when the second cutting saw 24 continues to move and ejects to the trunk, the trunk itself is too thick to be cut, which may cause the second cutting saw 24 to break or get stuck inside the trunk. When the second spring 23 and the symmetrical telescopic rod 22 work together to cut the branch and contact the trunk, the second spring 23 undergoes elastic deformation, and the telescopic rod 22 extends and retracts, realizing a buffering effect and protecting the second cutting saw 24.

[0047] The included angle between the fixing rod 21 and the I-shaped bracket 10 is 145 degrees.

[0048] A symmetrical fixing strip 4 is fixed to the arc surface of the symmetrical arc bracket 1. The symmetrical fixing strip 4 is fixedly connected to both ends of the V-shaped bracket 2. The V-shaped bracket 2 is rotatably connected to one end of the hand handle 3.

[0049] In this embodiment, the device is moved along the tree trunk by the handheld rod 3 and the V-shaped bracket 2. The arc-shaped cut along the surface of the tree trunk can minimize residue. The handheld part is far away from the cutting saw teeth to prevent injury.

[0050] The inner arc surface of the symmetrical arc-shaped support 1 is a smooth arc surface, which facilitates the movement of the arc-shaped support 1 along the tree trunk.

[0051] The outer shell of the electric push rod 5 is provided with a protective cover and is fixedly connected to the U-shaped rod 6. In this embodiment, the protective cover is provided to facilitate hand-holding and to protect the electric push rod 5.

[0052] In this embodiment, a sensor and a controller are also provided. The sensor is a distance sensor, which is located on the side of the cutting saw tooth 20 away from the electric push rod 5. The sensor and the controller communicate with each other, and the sensor is electrically connected to the controller. The controller is electrically connected to the electric push rod 5. When the sensor detects a branch, the controller controls the electric push rod 5 to complete one extension and retraction, that is, to complete one cutting operation. After the extension and retraction rod of the electric push rod 5 retracts, the device is moved by pushing the hand handle 3. When the sensor detects a branch, a catapult cutting operation can be performed. This process is repeated to continuously cut branches on the surface of the tree trunk.

[0053] When using the device, place it on the tree trunk surface, ensuring it can move stably along the trunk surface. Hold the handle 3 and move the device along the trunk to the branch that needs to be cut.

[0054] If the equipment is equipped with a sensor, when the sensor detects a branch, the controller will automatically control the electric push rod 5 to complete one extension and retraction to achieve the cutting operation. If there is no sensor or manual operation is required, the movement and ejection of the cutting module can be controlled by operating the electric push rod 5.

[0055] After the telescopic rod of the electric push rod 5 retracts, the device is moved to the next branch position by pushing the hand lever 3. The above steps are repeated to continuously cut branches off the surface of the tree trunk.

[0056] In this embodiment, when in use, the arc-shaped bracket 1 does not need to be pressed too tightly against the tree trunk to prevent the cutting saw teeth 20 from being unable to move forward or backward. The device only needs to be slightly attached to the tree trunk to achieve the cutting operation. It is fine as long as it does not deviate too far from the tree trunk. Therefore, this device can be used for tree trunks with a wide range of diameters.

[0057] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
