Summary of the invention

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

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an agricultural wood cutting device, comprising a frame, a first conveyor belt arranged on one side of the top of the frame and used for conveying wood, a plurality of first saw blades arranged on the frame and located above the first conveyor belt for cutting wood, a first motor for driving each first saw blade to rotate, a lifting and lowering adjustment unit for driving the first motor to lift, a second conveyor belt arranged on the other side of the top of the frame, a cutting mechanism arranged between the first conveyor belt and the second conveyor belt, a dust cover for surrounding the first saw blade and the cutting mechanism, and a guide mechanism arranged on the dust cover and located above the first conveyor belt; The cutting mechanism includes a chain conveyor, a connecting frame arranged on the frame and located 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 platform 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 platform, 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, and the fixed shaft passes through the guide platform.

[0005] Furthermore, a positioning fixture is provided on one side of the first conveyor belt, and the positioning fixture includes a positioning block, a driving device for driving the two positioning blocks to move toward the middle, a guide rod slidably arranged in the positioning block, a pulley arranged on the side of the guide rod away from the positioning block, a positioning spring arranged on the outside of the guide rod and located between the slider and the positioning block, and a limit block arranged on the side of the guide rod away from the pulley.

[0006] Furthermore, the diameter of the second bevel gear is greater than the diameter of the first bevel gear.

[0007] 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 fourth motor output shaft and meshing with the gear shaft.

[0008] Furthermore, a vertical rod is provided at the bottom of the guide platform, a third slider is slidably connected to the bottom of the vertical rod, a fitting block is provided 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 provided between the circular gear and the fitting block, and a guide surface in contact with the vertical rod is provided on the side of the third rack close to the vertical rod.

[0009] Furthermore, the third bevel gear and the fourth bevel gear have the same size.

[0010] Based on the same inventive concept, a method for cutting agricultural wood is also proposed, which is applied to the above agricultural wood cutting device and comprises the following steps: In the first step, the height of the first saw blade is adjusted by the lifting and lowering adjustment unit. After the height is adjusted, the wood to be cut is placed on the first conveyor belt. When the wood is fed through the first conveyor belt, the driving device drives the front and rear positioning blocks to move toward the middle, and the positioning blocks drive the pulley to move toward the middle until it contacts the wood. After the pulley contacts the surface of the wood, the driving device continues to drive the pulley to move toward the middle. Under the action of the positioning spring, the wood is positioned in the middle and fed in the middle. In the second step, the first conveyor belt conveys the wood to the right. When the wood reaches the bottom of the guide mechanism, the guide frame presses down the input wood under the action of the first spring, and conveys the input wood from left to right. After the surface bark of the wood is cut, the wood is rotated 90 degrees, and the height of the first saw blade is adjusted by the lifting adjustment unit. After completion, the wood is placed on the second conveyor belt, and the second conveyor belt inputs the wood and outputs it from right to left until the surface bark of the wood is cut. Since the dust hood surrounds the first conveyor belt and the second conveyor belt, the dust hood blocks the cutting dust inside the dust hood. In the third step, after the bark of the wood is cut, the wood is placed on the first conveyor belt. When the wood passes under the cutting mechanism, the first rotating shaft and the second rotating shaft drive the guide platform to move downward through the third guide rod and the fourth guide rod. Since the fixed shaft is fixedly connected to the fourth guide rod, the second rotating shaft drives the second bevel gear to rotate when the fourth guide rod rotates. The second bevel gear drives the second saw blade to rotate through the first bevel gear and the third rotating shaft. The third guide rod and the fourth guide rod rotate, which drives the guide platform and the second saw blade to move back and forth from top to bottom and from left to right. During the downward movement of the second saw blade, the wood transported by the chain conveyor will be cut and divided. At the same time, the second saw blade has the same moving speed as the chain conveyor. During the cutting process, the horizontal and vertical cutting of the wood can be completed at one time.

[0011] By adopting the above technical solution, the beneficial effects of the present invention are: The agricultural wood cutting device and its working method are provided by a cutting mechanism, wherein the second saw blade will cut and divide the length of wood transported by the chain conveyor during the downward movement, and the second saw blade and the chain conveyor move at the same speed, and the horizontal and vertical cutting of the wood can be completed at one time during the cutting process, thereby solving the problem that the existing cutting device needs to cut the thickness of the wood and then cut the length of the wood, resulting in a long cutting time of the cutting device.

DETAILED DESCRIPTION

[0031] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0032] refer to Figures 1 to 18The present embodiment provides an agricultural wood cutting device, comprising a frame, a first conveyor belt 1 provided on one side of the top of the frame and used for conveying wood, a plurality of first saw blades 2 provided on the frame and located above the first conveyor belt 1 for cutting wood, a first motor 3 for driving each of the first saw blades 2 to rotate, a lifting and lowering adjustment unit 4 for driving the first motor 3 to rise and fall, a second conveyor belt 5 provided on the other side of the top of the frame, a cutting mechanism 6 provided between the first conveyor belt 1 and the second conveyor belt 5, a dust cover 7 for surrounding the first saw blades 2 and the cutting mechanism 6, and a dust cover 7 provided on the dust cover 7 and located at A guiding mechanism 8 is provided above the first conveyor belt 1, and a positioning fixture 9 is provided on one side of the first conveyor belt 1. The positioning fixture 9 includes positioning blocks 901 provided 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 toward the middle, a guide rod 903 slidingly provided in the positioning block 901, a pulley 904 provided on the side of the guide rod 903 away from the positioning block 901, a positioning spring 905 provided on the outside of the guide rod 903 and located between the pulley 904 and the positioning block 901, and a limit block 906 provided on the side of the guide rod 903 away from the pulley 904.

[0033] The driving device 902 is two cylinders, or other devices that achieve equivalent functions, which are all prior art and will not be described in detail here. 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 toward the middle, and the positioning blocks 901 drive the pulley 904 to move toward the middle until it contacts the wood. During the initial cutting, the surface of the wood is not peeled and the depth varies. After the pulley 904 contacts the surface of the wood, the driving device 902 continues to drive the pulley 904 to move toward the middle. Under the action of the positioning spring 905, the wood will be centered and input centered, which has a good positioning effect on the wood during the cutting process.

[0034] First, the height of the first saw blade 2 is adjusted by the lifting and adjusting 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 the bottom of the guide mechanism 8. Under the action of the first spring 805, the guide frame 804 presses down the input wood and conveys the input wood from left to right. After cutting the surface bark of the wood, the wood is rotated 90°, and the height of the first saw blade 2 is adjusted by the lifting and adjusting unit 4. After completion, the wood is placed on the second conveyor belt 5. The second conveyor belt 5 inputs the wood and outputs it from right to left until the surface bark of the wood is cut. Since the dust hood 7 surrounds the first conveyor belt 1 and the second conveyor belt 5, the dust hood 7 blocks the cutting dust inside the dust hood 7 to prevent excessive cutting dust during use.

[0035] The guide mechanism 8 includes a mounting plate 801 disposed on the frame, a guide shaft 802 disposed on the top of the mounting plate 801, a second motor 803 for driving the guide shaft 802 to rotate, a guide frame 804 rotatably disposed on the outside of the guide shaft 802, a first spring 805 disposed between the dust cover 7 and the guide frame 804, a first rotating rod 806 rotatably disposed on the side of the guide frame 804 away from the mounting plate 801, a second rotating rod 807 disposed at an interval from the first rotating rod 806, and a second rotating rod 808 disposed between the first rotating rod 806 and the second rotating rod 808. a first guide block 808, a plurality of first sliders 809 arranged at equal angles on the outside of the first guide block 808, a first protruding block 810 arranged on one side of each first slider 809, a first guide rod 811 hingedly arranged on both sides of the first protruding block 810, a first moving block 812 arranged on the side of the first guide rod 811 away from the first protruding block 810, a connecting plate 813 arranged on the other side of each first slider 809, a first rack 814 arranged on the side of the connecting plate 813 away from the first guide block 808, and a first guide rod 811 hingedly arranged on both sides of the first protruding block 810. The second slider 815 on the outer side of each second slider 808, a second protruding block 816 provided on one side of the second slider 815, a second guide rod 817 hingedly provided on the outer side of the second protruding block 816, a second moving block 818 provided on one side of the second guide rod 817, a cross 819 provided on the other side of each second slider 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 first half gear 821 provided on one side of the first rotating rod 806 and meshing with the second rack 820 The second half gear 822, the third motor 823 for driving the first half gear 821 and the second half gear 822 to rotate, the first pulley 824 arranged on one side of the first rotating rod 806, the second pulley 825 arranged on one side of the guide shaft 802, and the annular belt 826 arranged between the first pulley 824 and the second pulley 825, the connecting plate 813 and the first rack 814 are provided with a center hole 827 in the middle part for the second rack 820 to pass through, and the tooth surfaces of the first rack 814 are distributed on the front and rear sides of the second rack 820.

[0036] A plurality of first protruding teeth 828 are disposed on the outer sides of the first moving block 812 and the second moving block 818. Fig.11The connection between the first guide rod 811 and the second guide rod 817 and the first moving block 812 and the second moving block 818 is 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 angle between the outer inclined surface of the first moving block 812 and the second moving block 818 and the second rotating rod 807 is 150°. The outer sides of the first moving block 812 and the second moving block 818 are slidably connected with a second raised tooth 831 located between the first raised tooth 828. A second spring 832 is provided between the second raised tooth 831 and the first moving block 812 and the second moving block 818. The bottom surface of the second raised tooth 831 contacts one side of the first guide rod 811 and the second guide rod 817.

[0037] When in use, the second motor 803 drives the second pulley 825 to rotate, and 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 is not 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, and the first moving block 812 and the second moving block 818 are arranged at intervals on the left and right. The third motor 823 drives the first half gear 821 and the second half gear 822 to rotate, and the tooth surfaces of the first half gear 821 and the second half gear 822 are arranged alternately, and the second half gear 822 drives the second rack 820 to move, and the movement of the second rack 820 drives the second slider 815 to move toward the blocking wall 830, and the second slider After the block 815 moves to the position close to the blocking wall 830 and is blocked, the second moving block 818 connected by the second protruding block 816 on the outer side of the second sliding block 815 through the second guide rod 817 will move outward after encountering resistance, and multiple second moving blocks 818 will be unfolded 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 staggered, the first rack 814 will drive the first sliding block 809 to move toward the blocking wall 830. The first guide rod 811 and the first moving block 812 connected to the first protruding block 810 on the outer side of the first sliding block 809 will contact the blocking wall 830 and will also unfold outward. The first moving block 812 will be unfolded to the second moving block Between the intervals between the moving blocks 818, the first protruding teeth 828 and the second protruding teeth 831 on the outer sides of the first moving block 812 and the second moving block 818 will protrude from the outer sides of the first rotating rod 806 and the second rotating rod 807. The surface of the unpeeled wood is uneven, and part of the tooth tip of the first protruding tooth 828 will be stuck in the unpeeled wood under the action of the downward pressure of the first spring 805. Since the contact ends of the first guide rod 811 and the second guide rod 817 and the second protruding teeth 831 are cam-shaped 829, the second protruding teeth 831 will be driven to move upward and protrude from the outer sides of the first protruding teeth 828. The first protruding teeth 828 and the second protruding teeth 831 will be deeply stuck in the surface of the unpeeled and uneven wood, pushing the wood toward the first saw blade 2 without manual assistance. In the existing method, the wood is input by clamping two horizontally arranged wheels or clamps, but the surface width of the unbarked wood is inconsistent, and it is difficult to keep in contact with the wood surface and push the wood in at a uniform speed. This structure can effectively keep the wood pushed in, and there is no need for manual assistance to push it in, which improves the safety during operation. When the bark on the surface of the wood is cut, the height of the first saw blade 2 is readjusted by the lifting and adjusting unit 4 when slicing is required. After completion, the wood is input from the first conveyor belt 1, and the third motor 823 drives the first half gear 821 and the second half gear 822 to rotate in the opposite direction. Since the first half gear 821 is in contact with the first rack 814 last, the first half gear 821 will first drive the first rack 814 to move in the direction away from the blocking wall 830.The first rack 814 drives the middle hole 827 of the connecting plate 813 to move rightward on the outside of the second rack 820, and the connecting plate 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 shrinks toward the inside of the second rotating rod 807, it will pass through the first moving block 812 and shrink into the inside of 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 inside of the second rotating rod 807 and move rightward to shrink 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 contacts, the second rack 820 drives the second slider 815 and the second moving block 818 on the second guide rod 817 to retract 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 on the left and right. At this time, the outer sides of the first rotating rod 806 and the second rotating rod 807 will be smooth and round. When the wood is input again, the surface of the wood after the bark is cut will not be damaged. The peeled wood can be guided for input. The wood peeling and slicing can be operated on the same device, which improves functionality.

[0038] The cutting mechanism 6 includes a chain conveyor 601, a connecting frame 602 arranged on a frame and located on both sides of the front and rear of 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, and a fourth rotating shaft 604 arranged on the side of the second rotating shaft 604 away from the synchronization mechanism 605.

[0039] The fixed shaft 610 passes through the guide platform 609, the diameter of the second bevel gear 615 is larger than the diameter 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, because the fixed shaft 610 is fixedly connected to the fourth guide rod 608, the second rotating shaft 604 drives the second bevel gear 615 to rotate when the fourth guide rod 608 rotates, and the second bevel gear 615 drives the fourth bevel gear 615 to rotate. The first bevel gear 614 and the third rotating shaft 612 drive the second saw blade 613 to rotate, and the third guide rod 607 and the fourth guide rod 608 rotate, which will drive the guide platform 609 and the second saw blade 613 to move back and forth from top to bottom and from left to right. During the downward movement of the second saw blade 613, the wood transported by the chain conveyor 601 will be cut and divided. 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, and during the vertical cutting, the chain conveyor 601 can cut synchronously without stopping.

[0040] A vertical rod 616 is provided at the bottom of the guide platform 609, and 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.

The third rack 619 moves to one side to clamp the input wood, and the guide platform 609 moves to the right synchronously. When the second saw blade 613 cuts the wood and moves upward, 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 to its original position without contacting the wood. The wood will be transported to the right, and the fitting block 618 will not contact the wood. It moves to the left under the action of the vertical rod 616 and the guide platform 609, and continues to reciprocately clamp the newly input material as the vertical rod 616 moves downward.

[0043] 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, and this structure has good synchronous driving stability.

[0044] Based on the same inventive concept, a method for cutting agricultural wood is also proposed, comprising the following steps: In the first step, the height of the first saw blade 2 is adjusted by the lifting adjustment unit 4. After the height is adjusted, 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 toward the middle, and the positioning blocks 901 drive the pulley 904 to move toward the middle until it contacts the wood. After the pulley 904 contacts the surface of the wood, the driving device 902 continues to drive the pulley 904 to move toward the middle. Under the action of the positioning spring 905, the wood is positioned in the middle, and the wood is input in the middle. In the second step, the first conveyor belt 1 conveys the wood to the right, and when it reaches the bottom of the guide mechanism 8, the guide frame 804 presses down the input wood under the action of the first spring 805, and conveys the input wood from left to right. After the surface bark of the wood is cut, the wood is rotated 90 degrees, and the height of the first saw blade 2 is adjusted by the lifting adjustment unit 4. After completion, the wood is placed on the second conveyor belt 5, and the second conveyor belt 5 inputs the wood and outputs it from right to left until the surface bark of the wood is cut. Since the dust hood 7 surrounds the first conveyor belt 1 and the second conveyor belt 5, the dust hood 7 blocks the cutting dust inside the dust hood 7; In the third step, after the bark of the wood is cut, the wood is placed on the first conveyor belt 1. When the wood passes under the cutting mechanism 6, 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, the second rotating shaft 604 drives the second bevel gear 615 to rotate when the fourth guide rod 608 rotates. 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 rotate, which drives the guide platform 609 and the second saw blade 613 to move back and forth from top to bottom and from left to right. During the downward movement of the second saw blade 613, the wood transported by the chain conveyor 601 is cut and divided. 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. The cutting method has high cutting efficiency and generates less dust.
