DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 6 The present invention is further described with reference to the accompanying drawings and embodiments.

[0032] A forestry trunk processing device comprises a symmetrically arranged arc bracket 1, on which a cutting module is slidably arranged, and the cutting module comprises a symmetrically arranged arc rod 7, between which the arc bracket 1 is arranged, and the two ends of the symmetrically arranged arc rod 7 are respectively fixedly connected to the two end portions of a limit shaft 18, and the symmetrical arc bracket 1 is respectively provided with an arc slide rail, in which two ends of the limit shaft 18 are respectively arranged, and one end of the arc rod 7 is fixedly connected to the corresponding end of the arc bracket 1 through a spring 3 8;

[0033] The arc rod 7 is arc-shaped in order to achieve the ejection to the end to avoid the position of the tree trunk.

[0034] One end of the symmetrically arranged arc bracket 1 is fixedly connected to the two ends of the cutting saw tooth 1 20, a limiting shaft 18 arranged in the arc slide rail is fixedly connected to the cutting saw tooth 2 bracket, the cutting saw tooth 2 bracket is connected to the cutting saw tooth 24, and the cutting saw tooth 24 and the cutting saw tooth 1 20 cooperate with each other;

[0035] In this embodiment, the arc bracket 1 is placed on the outer wall surface of the vertical rod, so that it moves along the outer wall surface to the branch of the tree trunk, the limit shaft 18 moves along the arc slide rail and drives the arc rod 7 to move, the spring three 8 undergoes elastic deformation, and the cutting module is ejected along the arc slide rail, and the cutting saw tooth two 24 can realize reciprocating motion, and when the cutting saw tooth two 24 is ejected in the direction of the cutting saw tooth one 20, the branch is cut;

[0036] Another limiting shaft 18 is arranged in the slot of the U-shaped rod 6, one end of the U-shaped rod 6 is fixedly connected to the support seat 25, the support seat 25 is fixedly connected to the lower side of the other end of the arc-shaped bracket 1 symmetrically, the U-shaped rod 6 is arranged horizontally, and the U-shaped rod 6 is connected to the driving assembly;

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

[0038] The driving assembly includes a transverse moving member, the transverse moving member is connected to the U-shaped rod 6, the transverse moving member is connected to the U-shaped moving rod 12, the two sides of the U-shaped moving rod 12 are respectively rotatably connected to the middle of the cross bar 16, one end of the cross bar 16 is fixedly connected to the inclined rod 15, the other end of the cross bar 16 is fixedly connected to the inclined rod 2 17, the angle between the inclined rod 15 and the cross bar 16 is 150 degrees, the angle between the inclined rod 2 17 and the cross bar 16 is 30 degrees, the end of the cross bar 16 away from the arc rod 7 is fixedly connected to one end of the spring 13, and the other end of the 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 three 8, and the springs three 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 blocking shaft 14 , the blocking shaft 14 matches the inclined rod 15 , and the inclined rod 2 17 matches the corresponding limiting shaft 18 .

[0041] In this embodiment, the lateral moving assembly drives the U-shaped moving rod 12 to move, and the U-shaped moving rod 12 drives the horizontal rod 16, the inclined rod 15, the inclined rod 2 17 and the spring 13 to move, and the movement of the cutting module is realized by the cooperation between the inclined rod 15 and the blocking shaft 14 and the cooperation between the limit shaft 18 and the inclined rod 2 17;

[0042] When the inclined rod 17 moves to abut the limit shaft 18, the inclined rod 17 is subjected to resistance. When the lateral moving assembly drives it to continue to move, the inclined rod 17 is fixed to the cross bar 16, and the cross bar 16 rotates to connect the U-shaped moving rod 12. The inclined rod 17 moves upward under the action of the driving force, driving the cross bar 16 to swing, and the spring 13 undergoes elastic deformation. When the inclined rod 17 is higher than the limit shaft 18, under the action of the rebound force of the spring 13, the inclined rod 17 swings downward to clamp the limit 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 is driven to move, and the cutting module moving spring three 8 is stretched until the inclined rod one 15 is against the blocking shaft 14. When the inclined rod one 15 continues to move in the opposite direction under the action of the lateral moving assembly, since the cross bar 16 rotates to connect the U-shaped moving rod 12, the angle between the inclined rod one 15 and the cross bar 16 is 150 degrees. At this time, the inclined rod one 15 moves downward under the reaction driving force, and the inclined rod two 17 moves upward until the inclined rod two 17 is separated from the limit shaft 18. At this time, the spring three 8 rebounds, driving the arc rod 7 to rebound, and the arc rod 7 drives the cutting module to eject to cut off the branch.

[0043] The transverse moving member is an electric push rod 5 , which fixes the U-shaped rod 6 , and the telescopic rod 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 extending and retracting the telescopic rod of the electric push rod 5, and the ejection movement of the cutting assembly is achieved by the driving assembly. When the cutting assembly is ejected, the driving assembly does not contact the cutting assembly, and the power is applied by the rebound force of the spring three 8, thereby avoiding wear on the driving assembly. Whether the resistance is large or small, it does not affect the use of the driving assembly.

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

[0046] In this embodiment, the I-shaped bracket 10 is arranged in the arc-shaped slide rail and matched therewith, which increases the stability of the cutting saw tooth two bracket when it moves. When in use, due to the large ejection force of the spring three 8, the cutting saw tooth two 24 continues to move and ejects to the tree trunk. The trunk will not be cut off due to its own thickness, which may cause the cutting saw tooth two 24 to collapse or get stuck inside the trunk. When the spring two 23 and the symmetrical telescopic rod 22 and the cutting saw tooth two 24 and the cutting saw tooth one 20 cooperate to cut the branch and contact the trunk, the spring two 23 undergoes elastic deformation, and the telescopic rod 22 extends and retracts to achieve a buffering effect, thereby protecting the cutting saw tooth two 24.

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

[0048] A symmetrical fixing bar 4 is fixed on the arc surface of the symmetrical arc-shaped bracket 1 , and the symmetrical fixing bar 4 is fixedly connected to two ends of the V-shaped bracket 2 , and the V-shaped bracket 2 is rotatably connected to one end of the hand-held rod 3 .

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

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

[0051] A protective cover is disposed on the outer side of the housing of the electric push rod 5 and is fixedly connected to the U-shaped rod 6 . In the present embodiment, the protective cover is provided for easy holding and protection of the electric push rod 5 .

[0052] In this embodiment, a sensor and a controller are also provided. The sensor is a distance sensor, and the sensor is provided on the side of the cutting saw tooth 20 away from the electric push rod 5. The sensor and the controller communicate, and the sensor electrical signal is connected to the controller, and the controller is electrically connected to the push rod 5. When the sensor detects a branch, the controller controls the electric push rod 5 to complete an extension, that is, to complete a cutting operation. In this way, after the extension rod of the electric push rod 5 retracts, the device is driven to move by the push of the hand-held rod 3. When the sensor detects a branch, a catapult cutting operation can be performed. This process is repeated to achieve continuous cutting of branches on the surface of the trunk.

[0053] When in use, the device is placed on the surface of the tree trunk, ensuring that it can be stably moved along the surface of the tree trunk, and the hand-held rod 3 is held to move the device along the tree trunk to the position of the branch that needs to be cut.

[0054] If the device is equipped with a sensor, when the sensor detects a branch, the controller will automatically control the electric push rod 5 to complete a retraction and realize 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 is retracted, the device is driven to move to the next branch position by pushing the hand-held rod 3, and the above steps are repeated to continuously cut off the branches on the surface of the 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 tooth 20 from being unable to move forward or backward. The device only needs to slightly fit the tree trunk to achieve the cutting operation and not be too far away from the tree trunk. Therefore, the device can be used for tree trunks with a wide range of diameters.

[0057] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
