Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to an agricultural wood cutting device and its working method. Background Art

[0002] At present, Chinese Patent Publication No.: CN108000631A discloses a wood cutting device, including a support frame. A wood placing frame capable of sliding left and right on the support frame is installed at the top of the support frame. Rotating rollers with both ends installed on the wood placing frame are arranged at intervals inside the wood placing frame. An activity frame is arranged on the right side of the support frame. A rotating shaft is fixedly installed at the top of the activity frame. A circular ring piece is installed at the lower end of the rotating shaft. A circular serrated electric cutting blade hanging over the wood placing frame is sleeved outside the circular ring piece. The cutting direction of the electric cutting blade is the same as the axial direction of the rotating roller. At least one electric cutting blade is provided, which discloses a wood cutting device with a general structure. However, in the existing wood cutting process, the wood is usually first cut into plates with the same thickness, and then cut into blocks with the same length again, which requires two cutting processes, resulting in a long cutting time. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes an agricultural wood cutting device and its working method, which solve the technical problem that the existing cutting device needs to cut the thickness of the wood first and then cut the length of the wood, resulting in a long cutting time of the cutting device.

[0004] To achieve the above object, the present invention adopts the following technical solutions: An agricultural wood cutting device includes a machine frame, a first conveyor belt arranged on one side of the top of the machine frame and used for conveying wood, a plurality of first saw blades arranged on the machine frame and above the first conveyor belt for cutting the wood, a first motor for driving each first saw blade to rotate, a lifting adjustment unit for driving the first motor to lift, a second conveyor belt arranged on the other side of the top of the machine frame, a cutting mechanism arranged between the first conveyor belt and the second conveyor belt, a dust suction hood for surrounding the first saw blades and the cutting mechanism, and a guiding mechanism arranged on the dust suction hood and above the first conveyor belt;

[0005] The cutting mechanism includes a chain conveyor, connecting frames arranged on the frame and on the front and rear sides above the chain conveyor, a first rotating shaft rotatably arranged on one side of the top of the connecting frame, a second rotating shaft rotatably arranged on the other side of the top of the connecting frame, a synchronization mechanism arranged at the rear end of the first rotating shaft, a fourth motor for driving the synchronization mechanism to rotate, a third guide rod arranged on the side of the first rotating shaft away from the synchronization mechanism, a fourth guide rod arranged on the side of the second rotating shaft away from the synchronization mechanism, a guide table rotatably connected to the third guide rod and the fourth guide rod, a fixed shaft fixedly arranged on the side of the second rotating shaft away from the connecting frame, an extension block extending in the middle of the guide table, a third rotating shaft rotatably arranged on the extension block, a second saw blade arranged on one side of the third rotating shaft, a first bevel gear arranged on the side of the third rotating shaft away from the second saw blade, and a second bevel gear fixedly arranged on the outside of the third rotating shaft and meshing with the first bevel gear. The fixed shaft passes through the guide table.

[0006] Furthermore, a positioning fixture is arranged on one side of the first conveyor belt. The positioning fixture includes positioning blocks, a driving device for driving the two positioning blocks to move towards the middle, guide rods slidably arranged in the positioning blocks, pulleys arranged on the sides of the guide rods away from the positioning blocks, positioning springs arranged on the outside of the guide rods and between the sliders and the positioning blocks, and limit blocks arranged on the sides of the guide rods away from the pulleys.

[0007] Furthermore, the diameter of the second bevel gear is larger than that of the first bevel gear.

[0008] Furthermore, the synchronization mechanism includes a third bevel gear arranged at one end of the first rotating shaft, a fourth bevel gear arranged at one end of the second rotating shaft, a gear shaft for meshing with the third bevel gear and the fourth bevel gear, and a fifth bevel gear arranged on the outside of the output shaft of the fourth motor and meshing with the gear shaft.

[0009] Furthermore, a vertical rod is arranged at the bottom of the guide table. A third slider is slidably connected to the bottom of the vertical rod. A fitting block is arranged on one side of the third slider. A third rack is slidably connected inside the fitting block. A circular gear is rotatably connected inside the fitting block. A torsion spring for driving the circular gear to rotate is arranged between the circular gear and the fitting block. A guiding surface in contact with the vertical rod is arranged on the side of the third rack close to the vertical rod.

[0010] Furthermore, the third bevel gear and the fourth bevel gear have the same size.

[0011] Based on the same inventive concept, an agricultural wood cutting working method is also proposed, which is applied to the above-mentioned agricultural wood cutting device and includes the following steps:

[0012] First step: First, adjust the height of the first saw blade through the lifting and lowering adjustment unit. After completion, place the wood to be cut on the first conveyor belt. When the wood is input through the first conveyor belt, the driving device drives the positioning blocks on both the front and rear sides to move towards the middle. The positioning blocks drive the pulleys to move towards the middle until they come into contact with the wood. After the pulleys come into contact with the wood surface, the driving device continues to drive the pulleys to move towards the middle. Under the action of the positioning spring, the wood is centered and positioned, and the wood will be input centered;

[0013] Second step: The first conveyor belt conveys the wood to the right. When it reaches below the guiding mechanism, under the action of the first spring, the guiding frame presses down the input wood, conveys the input wood from left to right, cuts the bark on the surface layer of the wood, rotates the wood by 90°, then adjusts the height of the first saw blade through the lifting and lowering adjustment unit. After completion, place the wood on the second conveyor belt. The second conveyor belt conveys the wood and outputs it from right to left until the bark on the wood surface is completely cut. Since the dust suction hood surrounds the first conveyor belt and the second conveyor belt, the dust suction hood blocks the cut dust inside the dust suction hood;

[0014] Third step: After cutting the bark of the wood, place the wood on the first conveyor belt again. The wood passes below the cutting mechanism. The first rotating shaft and the second rotating shaft drive the guiding platform to move downward through the third guiding rod and the fourth guiding rod. Since the fixed shaft is fixedly connected to the fourth guiding rod, when the second rotating shaft drives the fourth guiding rod to rotate, it drives the second bevel gear to rotate. The second bevel gear drives the second saw blade to rotate through the first bevel gear and the third rotating shaft. The third guiding rod and the fourth guiding rod perform a rotating motion, which drives the guiding platform and the second saw blade to reciprocate from top to bottom and from left to right. During the downward movement of the second saw blade, it will cut and divide the wood conveyed by the chain conveyor. At the same time, the second saw blade has the same moving speed as the chain conveyor, and the horizontal and vertical cutting of the wood can be completed in one go during the cutting process.

[0015] By adopting the foregoing technical solutions, the beneficial effects of the present invention are:

[0016] For this agricultural wood cutting device and its working method, through the setting of the cutting mechanism, during the downward movement of the second saw blade, it will cut and divide the length of the wood conveyed by the chain conveyor. At the same time, the second saw blade has the same moving speed as the chain conveyor, and the horizontal and vertical cutting of the wood can be completed in one go during the cutting process, solving the problem that the existing cutting device needs to cut the thickness of the wood first and then cut the length of the wood, resulting in a long cutting time for the cutting device.

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0041] Refer to Figures 1 to 18, this embodiment provides a wood cutting device for agriculture, which includes a frame, a first conveyor belt 1 arranged on one side of the top of the frame and used for conveying wood, a plurality of first saw blades 2 arranged on the frame and above the first conveyor belt 1 for cutting wood, a first motor 3 for driving each first saw blade 2 to rotate, a lifting adjustment unit 4 for driving the first motor 3 to lift and lower, a second conveyor belt 5 arranged on the other side of the top of the frame, a cutting mechanism 6 arranged between the first conveyor belt 1 and the second conveyor belt 5, a dust suction hood 7 for surrounding the first saw blades 2 and the cutting mechanism 6, and a guiding mechanism 8 arranged on the dust suction hood 7 and above the first conveyor belt 1. A positioning fixture 9 is arranged on one side of the first conveyor belt 1. The positioning fixture 9 includes positioning blocks 901 arranged on the front and rear sides of the first conveyor belt 1, a driving device 902 for driving the two positioning blocks 901 to move towards the middle, a guide rod 903 slidably arranged in the positioning block 901, a pulley 904 arranged on the side of the guide rod 903 away from the positioning block 901, a positioning spring 905 arranged on the outer side of the guide rod 903 and between the pulley 904 and the positioning block 901, and a limit block 906 arranged on the side of the guide rod 903 away from the pulley 904.

[0042] The driving device 902 is two cylinders or other devices with the same function, which are all prior arts and will not be elaborated here. When in use, when the wood is input through the first conveyor belt 1, the driving device 902 drives the positioning blocks 901 on the front and rear sides to move towards the middle. The positioning blocks 901 drive the pulleys 904 to move towards the middle until they contact the wood. When the wood is cut for the first time, the surface of the wood is not peeled and the depths are different. After the pulleys 904 contact the surface of the wood, the driving device 902 continues to drive the pulleys 904 to move towards the middle. Under the action of the positioning spring 905, the wood will be centered and positioned, and the wood will be centered and input, and the positioning effect on the wood during the cutting process is good.

[0043] First, adjust the height of the first saw blade 2 through the lifting adjustment unit 4. After completion, the wood to be cut is placed on the first conveyor belt 1. The first conveyor belt 1 conveys the wood to the right and reaches below the guiding mechanism 8. Under the action of the first spring 805, the guiding frame 804 presses down the input wood and conveys the input wood from left to right. After cutting the bark on the surface of the wood, rotate the wood by 90°. Then, adjust the height of the first saw blade 2 through the lifting adjustment unit 4. After completion, place the wood on the second conveyor belt 5. The second conveyor belt 5 conveys the wood and outputs it from right to left until the bark on the surface of the wood is completely cut. Since the dust suction hood 7 surrounds the first conveyor belt 1 and the second conveyor belt 5, the dust suction hood 7 blocks the cutting dust inside the dust suction hood 7, preventing a large amount of cutting dust during use.

[0044] The guiding mechanism 8 includes a mounting plate 801 provided on the frame, a guiding shaft 802 provided on the top of the mounting plate 801, a second motor 803 for driving the rotation of the guiding shaft 802, a guiding frame 804 rotatably provided outside the guiding shaft 802, a first spring 805 provided between the dust suction hood 7 and the guiding frame 804, a first rotating rod 806 rotatably provided on the side of the guiding frame 804 away from the mounting plate 801, a second rotating rod 807 arranged at an interval with the first rotating rod 806, a first guiding block 808 provided between the first rotating rod 806 and the second rotating rod 807, a plurality of first sliding blocks 809 arranged at equal angular intervals outside the first guiding block 808, a first protruding block 810 provided on one side of each first sliding block 809, a first guiding rod 811 hinged on both sides of the first protruding block 810, a first moving block 812 provided on the side of the first guiding rod 811 away from the first protruding block 810, a connecting disk 813 provided on the other side of each first sliding block 809, a first rack 814 provided on the side of the connecting disk 813 away from the first guiding block 808, a second sliding block 815 slidably provided outside the first guiding block 808, a second protruding block 816 provided on one side of the second sliding block 815, a second guiding rod 817 hinged outside the second protruding block 816, a second moving block 818 provided on one side of the second guiding rod 817, a cross 819 provided on the other side of each second sliding block 815, a second rack 820 provided in the middle of the cross 819, a first half gear 821 provided on one side of the first rotating rod 806 and meshing with the first rack 814, a second half gear 822 provided on one side of the first rotating rod 806 and meshing with the second rack 820, a third motor 823 for driving the rotation of the first half gear 821 and the second half gear 822, a first pulley 824 provided on one side of the first rotating rod 806, a second pulley 825 provided on one side of the guiding shaft 802, and an annular belt 826 provided between the first pulley 824 and the second pulley 825. A middle hole 827 for the second rack 820 to pass through is provided in the middle of the connecting disk 813 and the first rack 814, and the tooth surface of the first rack 814 is distributed on the front and back sides of the second rack 820.

[0045] A plurality of first protruding teeth 828 are provided on the outside of the first moving block 812 and the second moving block 818. Refer to Figure 11, the connection parts of the first guide rod 811 and the second guide rod 817 with the first moving block 812 and the second moving block 818 are in the shape of a cam 829. A blocking wall 830 for blocking the first moving block 812 and the second moving block 818 is provided on one side of the first rotating rod 806. The included angle between the outer inclined surfaces of the first moving block 812 and the second moving block 818 and the second rotating rod 807 is 150°. Second raised teeth 831 are slidably connected between the outer sides of the first moving block 812 and the second moving block 818 and located between the first raised teeth 828. A second spring 832 is provided between the second raised teeth 831 and the first moving block 812 and the second moving block 818. The bottom surface of the second raised teeth 831 is in contact with one side of the first guide rod 811 and the second guide rod 817.

[0046] During use, the second motor 803 drives the second pulley 825 to rotate. The second pulley 825 drives the first rotating rod 806 and the second rotating rod 807 to rotate through the annular belt 826 and the first pulley 824. When the bark on the surface of the input wood has not been removed, the first moving block 812 and the second moving block 818 are inside the first rotating rod 806 and the second rotating rod 807. The first moving block 812 and the second moving block 818 are arranged at intervals left and right. The third motor 823 drives the first half gear 821 and the second half gear 822 to rotate. The tooth surfaces of the first half gear 821 and the second half gear 822 are arranged staggeredly. The second half gear 822 drives the second rack 820 to move. The movement of the second rack 820 drives the second slider 815 to move towards the blocking wall 830. After the second slider 815 moves to a position close to the blocking wall 830 and is blocked, the second protruding block 816 on the outside of the second slider 815 will drive the second moving block 818 connected by the second guide rod 817 to move outward when it is resisted. Multiple second moving blocks 818 will expand outward. As the third motor 823 continues to rotate, the first half gear 821 contacts the first rack 814. Since the second moving block 818 and the first moving block 812 are arranged in a staggered manner, the first rack 814 will drive the first slider 809 to move towards the blocking wall 830. The first guide rod 811 and the first moving block 812 connected to the first protruding block 810 on the outside of the first slider 809 will also expand outward when they contact the blocking wall 830. The first moving block 812 will expand to the interval between the second moving blocks 818. The first protruding teeth 828 and the second protruding teeth 831 on the outside of the first moving block 812 and the second moving block 818 will protrude outside the first rotating rod 806 and the second rotating rod 807. The surface of the unpeeled wood is uneven. Part of the tooth tips of the first protruding teeth 828 will be stuck into the unpeeled wood under the downward pressure of the first spring 805. Since the contact ends of the first guide rod 811 and the second guide rod 817 with the second protruding teeth 831 are cam-shaped 829, it will drive the second protruding teeth 831 to move upward and protrude outside the first protruding teeth 828. The first protruding teeth 828 and the second protruding teeth 831 will deeply penetrate into the uneven surface of the unpeeled wood and push the wood towards the first saw blade 2. There is no need for manual assistance to push. In the existing part, the wood is input by clamping it with two horizontally arranged wheels or fixtures. However, the width of the surface of the wood without bark is inconsistent, and it is difficult to keep in contact with the wood surface and push the wood at a uniform speed. This structure can effectively keep the wood pushed in and does not require manual assistance to push, improving the safety during operation. When the bark on the four-week surface of the wood is cut, when slicing is required, the height of the first saw blade 2 is readjusted through the lifting adjustment unit 4. After that, the wood is input from the first conveyor belt 1 again. At the same time, the third motor 823 drives the first half gear 821 and the second half gear 822 to rotate in the reverse direction. Since the first half gear 821 contacts the first rack 814 last, the first half gear 821 will first drive the first rack 814 to move away from the blocking wall 830.The first rack 814 drives the middle hole 827 of the connecting disk 813 to move rightward outside the second rack 820. The connecting disk 813 drives the first moving block 812 to move rightward through the first slider 809 and the first guide rod 811. Since the volume of the first moving block 812 is smaller than that of the second moving block 818, when the first moving block 812 contracts toward the inner side of the second rotating rod 807, it will pass through the first moving block 812 and contract into the second rotating rod 807. After the outer inclined surface of the first moving block 812 contacts the outer notch of the second rotating rod 807, it will slide into the second rotating rod 807 and move rightward to contract to the middle position of the second rotating rod 807. As the third motor 823 continues to rotate, the second half gear 822 will contact the second rack 820. The second rack 820 drives the second moving block 818 on the second slider 815 and the second guide rod 817 to contract into the notch of the second rotating rod 807 through the cross 819. Since the outer inclined surface of the second moving block 818 contacts the outer notch of the second rotating rod 807, it will slide into the second rotating rod 807 near the notch. The first moving block 812 and the second moving block 818 inside the second rotating rod 807 are arranged at intervals left and right. At this time, the outer sides of the first rotating rod 806 and the second rotating rod 807 will be smooth circles, and the wood will not damage the surface of the wood after cutting the bark when input, guiding the input of the peeled wood. The wood peeling and slicing can be operated by the same device, improving functionality.

[0047] The cutting mechanism 6 includes a chain conveyor 601, connecting frames 602 arranged on the frame and on the front and rear sides above the chain conveyor 601, a first rotating shaft 603 rotatably arranged on one side of the top of the connecting frame 602, a second rotating shaft 604 rotatably arranged on the other side of the top of the connecting frame 602, a synchronization mechanism 605 arranged at the rear end of the first rotating shaft 603, a fourth motor 606 for driving the synchronization mechanism 605 to rotate, a third guide rod 607 arranged on the side of the first rotating shaft 603 away from the synchronization mechanism 605, a fourth guide rod 608 arranged on the side of the second rotating shaft 604 away from the synchronization mechanism 605, a guide table 609 rotatably connected to the third guide rod 607 and the fourth guide rod 608, a fixed shaft 610 fixedly arranged on the side of the second rotating shaft 604 away from the connecting frame 602, an extension block 611 extending in the middle of the guide table 609, a third rotating shaft 612 rotatably arranged on the extension block 611, a second saw blade 613 arranged on one side of the third rotating shaft 612, a first bevel gear 614 arranged on the side of the third rotating shaft 612 away from the second saw blade 613, and a second bevel gear 615 fixedly arranged on the outside of the third rotating shaft 612 and meshing with the first bevel gear 614.

[0048] The fixed shaft 610 passes through the guide platform 609. The diameter of the second bevel gear 615 is larger than that of the first bevel gear 614. The fourth motor 606 drives the first rotating shaft 603 and the second rotating shaft 604 to rotate synchronously through the synchronization mechanism 605. The first rotating shaft 603 and the second rotating shaft 604 drive the guide platform 609 to move downward through the third guide rod 607 and the fourth guide rod 608. Since the fixed shaft 610 is fixedly connected to the fourth guide rod 608, when the second rotating shaft 604 drives the fourth guide rod 608 to rotate, the second bevel gear 615 is driven to rotate. The second bevel gear 615 drives the second saw blade 613 to rotate through the first bevel gear 614 and the third rotating shaft 612. The third guide rod 607 and the fourth guide rod 608 perform a rotating motion, which will drive the guide platform 609 and the second saw blade 613 to reciprocate from top to bottom and from left to right. During the downward movement of the second saw blade 613, the wood conveyed by the chain conveyor 601 will be cut and divided. At the same time, the moving speed of the second saw blade 613 is the same as that of the chain conveyor 601. During the cutting process, the horizontal and vertical cutting of the wood can be completed at one time. And during the vertical cutting, the chain conveyor 601 does not need to stop and can perform synchronous cutting.

[0049] A vertical rod 616 is provided at the bottom of the guide platform 609. A third slider 617 is slidably connected to the bottom of the vertical rod 616. A fitting block 618 is provided on one side of the third slider 617. A third rack 619 is slidably connected inside the fitting block 618. A circular gear 620 is rotatably connected inside the fitting block 618. A torsion spring 621 for driving the circular gear 620 to rotate is provided between the circular gear 620 and the fitting block 618. A guiding surface 622 in contact with the vertical rod 616 is provided on one side of the third rack 619 close to the vertical rod 616.

[0050] During the downward movement of the guide platform 609, the vertical rod 616 is driven to move downward. The vertical rod 616 moves downward inside the third slider 617. During the movement, it contacts the guiding surface 622 of the third rack 619. The third rack 619 moves to one side to clamp the input wood and synchronously moves the guide platform 609 to the right. When the second saw blade 613 moves upward after cutting the wood, the vertical rod 616 will also move upward. Under the action of the torsion spring 621, the circular gear 620 drives the third rack 619 to move back to its original position and not contact the wood. The wood will be conveyed to the right, and the fitting block 618 does not contact the wood. Under the action of the vertical rod 616 and the guide platform 609, it moves to the left, and continues to clamp the newly input material reciprocally as the vertical rod 616 moves downward.

[0051] The synchronization mechanism 605 includes a third bevel gear 623 provided at one end of the first rotating shaft 603, a fourth bevel gear 624 provided at one end of the second rotating shaft 604, a gear shaft 625 for meshing with the third bevel gear 623 and the fourth bevel gear 624, and a fifth bevel gear 626 provided outside the output shaft of the fourth motor 606 and meshing with the gear shaft 625. The third bevel gear 623 and the fourth bevel gear 624 are of the same size.

[0052] The fourth motor 606 drives the fifth bevel gear 626 to rotate. The fifth bevel gear 626 drives the gear shaft 625 to rotate. The rotation of the gear shaft 625 drives the fourth bevel gear 624 and the third bevel gear 623 to rotate. The third bevel gear 623 and the fourth bevel gear 624 simultaneously drive the second rotating shaft 604 and the first rotating shaft 603 to rotate synchronously. This structure has good synchronization driving stability.

[0053] Based on the same inventive concept, an agricultural wood cutting working method is also proposed, including the following steps:

[0054] In the first step, first, the height of the first saw blade 2 is adjusted by the lifting adjustment unit 4. After completion, the wood to be cut is placed on the first conveyor belt 1. When the wood is input through the first conveyor belt 1, the driving device 902 drives the positioning blocks 901 on the front and rear sides to move towards the middle. The positioning blocks 901 drive the pulleys 904 to move towards the middle until they contact the wood. After the pulleys 904 contact the wood surface, the driving device 902 continues to drive the pulleys 904 to move towards the middle. Under the action of the positioning spring 905, the wood is centered and positioned, and the wood will be input centered.

[0055] In the second step, the first conveyor belt 1 conveys the wood to the right. When it reaches below the guiding mechanism 8, under the action of the first spring 805, the guiding frame 804 presses down the input wood, conveys the input wood from left to right, cuts the bark on the surface of the wood, rotates the wood by 90°, and then adjusts the height of the first saw blade 2 by the lifting adjustment unit 4. After completion, the wood is placed on the second conveyor belt 5. The second conveyor belt 5 conveys the wood and outputs it from right to left until the bark on the surface of the wood is completely cut. Since the dust suction hood 7 surrounds the first conveyor belt 1 and the second conveyor belt 5, the dust suction hood 7 blocks the cut dust within the dust suction hood 7.

[0056] Step 3: After cutting the wood bark, place the wood on the first conveyor belt 1. The wood passes under the cutting mechanism 6. The first rotating shaft 603 and the second rotating shaft 604 drive the guide table 609 to move downward through the third guide rod 607 and the fourth guide rod 608. Since the fixed shaft 610 is fixedly connected to the fourth guide rod 608, when the second rotating shaft 604 drives the fourth guide rod 608 to rotate, it drives the second bevel gear 615 to rotate. The second bevel gear 615 drives the second saw blade 613 to rotate through the first bevel gear 614 and the third rotating shaft 612. The third guide rod 607 and the fourth guide rod 608 perform a rotating motion, which will drive the guide table 609 and the second saw blade 613 to reciprocate from top to bottom and from left to right. During the downward movement of the second saw blade 613, it will cut and divide the wood conveyed by the chain conveyor 601. At the same time, the second saw blade 613 has the same moving speed as the chain conveyor 601. During the cutting process, the horizontal and vertical cutting of the wood can be completed at one time. This cutting method has high cutting efficiency and produces less dust.

7. A working method for cutting wood in agriculture, which is applied to the wood cutting device for agriculture described in claim 6 above, and is characterized in that, Including the following steps: In the first step, first adjust the height of the first saw blade (2) through the lifting and adjusting unit (4). After completion, the wood to be cut is placed on the first conveyor belt (1). When the wood is input through the first conveyor belt (1), the driving device (902) drives the front and rear positioning blocks (901) to move towards the middle. The positioning blocks (901) drive the pulleys (904) to move towards the middle until they contact the wood. After the pulleys (904) contact the wood surface, the driving device (902) continues to drive the pulleys (904) to move towards the middle. Under the action of the positioning spring (905), the wood is centered and positioned, and the wood will be input in the center; In the second step, the first conveyor belt (1) conveys the wood to the right. When it reaches below the guiding mechanism (8), under the action of the first spring (805), the guiding frame (804) presses down the incoming wood, conveys the incoming wood from left to right, cuts the bark on the surface of the wood, rotates the wood by 90°, then adjusts the height of the first saw blade (2) through the lifting adjustment unit (4). After completion, the wood is placed on the second conveyor belt (5). The second conveyor belt (5) conveys the wood and outputs it from right to left until the bark on the surface of the wood is completely cut. When the bark on the four surrounding surfaces of the wood is cut and slicing is required, the height of the first saw blade (2) is readjusted through the lifting adjustment unit (4). After completion, the wood is input from the first conveyor belt (1) again. Since the dust suction hood (7) surrounds the first conveyor belt (1) and the second conveyor belt (5), the dust suction hood (7) blocks the cut dust within the dust suction hood (7); In the third step, after cutting the bark of the wood, the wood is placed on the first conveyor belt (1). The wood passes below the cutting mechanism (6). The first rotating shaft (603) and the second rotating shaft (604) drive the guiding platform (609) to move downward through the third guiding rod (607) and the fourth guiding rod (608). Since the fixed shaft (610) is fixedly connected to the fourth guiding rod (608), when the second rotating shaft (604) drives the fourth guiding rod (608) to rotate, it drives the second bevel gear (615) to rotate. The second bevel gear (615) drives the second saw blade (613) to rotate through the first bevel gear (614) and the third rotating shaft (612). The third guiding rod (607) and the fourth guiding rod (608) perform a rotating motion, which will drive the guiding platform (609) and the second saw blade (613) to reciprocate from top to bottom and from left to right. During the downward movement of the second saw blade (613), it will cut and divide the wood conveyed by the chain conveyor (601). At the same time, the second saw blade (613) has the same moving speed as the chain conveyor (601), and the horizontal and vertical cutting of the wood can be completed in one go during the cutting process.
