[0002] In agriculture, trees need to be cut down after they enter the senescent stage. To allow the trees to decompose quickly and be used to nourish the soil, the common practice is to slice the trees. For example, palm trees enter the harvesting period in about 3 years, and after about 20 years of harvesting, they enter the senescent stage. Trees in the senescent stage have reduced productivity and are then cut down to enter the next planting cycle.

[0003] A slicing device for slicing trees has been developed in the prior art, which includes a gripping component for grasping the tree and a cutting component for slicing. However, this prior art requires manual feeding of the tree into the cutting component, resulting in low slicing efficiency. Utility Model Content

Detailed Implementation

[0025] In agriculture, trees need to be cut down when they enter the aging stage. In order to allow the trees to decompose quickly and be used to nourish the soil, the common practice is to slice the trees.

[0026] A slicing device for slicing trees has been developed in the prior art, which includes a gripping component for grasping the tree and a cutting component for slicing. However, this prior art requires manual feeding of the tree into the cutting component, resulting in low slicing efficiency.

[0027] To overcome the shortcomings of existing technologies, this application provides a slicing device. Since the feed wheel of the feeding mechanism is positioned above the gripping assembly, and the slicing mechanism is positioned behind the feeding mechanism, after the two grippers grasp the forest into the processing space, the feed wheel of the feeding mechanism transports the trees towards the slicing mechanism. When the trees reach the blade position of the slicing mechanism, they are sliced. As the feeding mechanism continuously feeds, the blade can slice the forest multiple times along its length at a certain frequency, eliminating the need for manual feeding of trees, making it safe and efficient.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1 to 5 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] This application provides a slicing device that can be used as an attachment for an excavator to slice trees.

[0030] In some embodiments, the slicing device may include a frame 100, a gripping mechanism 200, a feeding mechanism 300, and a slicing mechanism 400. The frame 100 has a processing space 140 with a downwardly opening inlet 110 and a rearwardly opening outlet 120. The gripping mechanism 200 has two gripping components, each with a gripper 210. The grippers 210 of the two gripping components are rotatably disposed on the left and right sides of the frame 100, respectively, and located at the inlet 110, to grip the wood to be processed by opening and closing. The feeding mechanism 300 has a feed wheel 310 disposed above the gripping components to feed the wood to be processed toward the outlet 120. The slicing mechanism 400 is disposed at the outlet 120 and has at least one cutter 410 for slicing the wood to be processed.

[0031] In this embodiment, the frame 100 can be mounted on the stick of the excavator via the mounting base 150. The frame 100 is used to push down and adjust the position of the tree by moving the stick. In some specific embodiments, the frame 100 can be equipped with a front fork 130, which has an arc-shaped push opening to facilitate the contact with the tree and thus push it down.

[0032] The frame 100 may have a processing space 140, which has a downward-opening feed inlet 110 and a rearward-opening discharge outlet 120. That is, the frame 100 can grab trees from below and then feed the forest from front to back to achieve slicing.

[0033] Furthermore, the front of the frame 100 may also be open to allow for the avoidance of longer trees, enabling the trees to enter the processing space 140 from below. In some specific embodiments, the frame 100 may be configured as a U-shape with the opening facing downwards. A mounting base 150 may be provided on the top of the frame 100 for mounting to the boom.

[0034] In this embodiment, the gripping mechanism 200 has two gripping components, each with a gripper 210. The grippers 210 of the two gripping components are rotatably disposed on the left and right sides of the frame 100 and located at the feed inlet 110. When the two grippers 210 rotate away from each other, the feed inlet can be opened; when the two grippers 210 rotate close to each other, the feed inlet can be closed. The position of the slicing device can be adjusted using the excavator's boom, allowing the fallen trees on the ground to enter the space between the two grippers 210. Then, the two grippers 210 close by rotating, allowing the trees to enter the processing space 140.

[0035] Because the feed wheel 310 of the feeding mechanism 300 is positioned above the gripping assembly, and the slicing mechanism 400 is positioned behind the feeding mechanism 300, after the two grippers 210 grasp the tree into the processing space 140, the feed wheel 310 of the feeding mechanism 300 transports the tree towards the slicing mechanism 400. When the tree reaches the position of the cutter 410 of the slicing mechanism 400, it is sliced. As the feeding mechanism 300 continuously feeds, the cutter 410 can slice the tree multiple times along its length at a certain frequency, eliminating the need for manual feeding of the tree, making it safe and efficient.

[0036] In some embodiments, each gripping assembly may further include a pivot 220 and a link 230. The pivot 220 is rotatably disposed on the side wall of the processing space 140, and the gripper 210 is connected to the pivot 220. The link 230 is connected to the pivot 220 and is used to drive the pivot 220 to rotate, thereby causing the gripper 210 to rotate.

[0037] In this embodiment, a set of rotating shafts 220 are respectively provided on the left and right inner sidewalls of the processing space 140. Both ends of the rotating shaft 220 are rotatably mounted on the hinge seat 270 so that they are rotatably connected to the sidewalls of the processing space 140. The connecting rod 230 is connected to the rotating shaft 220. When the connecting rod 230 is driven to rotate, the connecting rod 230 can drive the rotating shaft 220 to rotate, and the rotating shaft 220 drives the gripper 210 to rotate.

[0038] Furthermore, the gripping mechanism 200 may also include a drive assembly for driving the connecting rods 230 of the two gripping assemblies to rotate, thereby driving the two grippers 210 to rotate. The drive assembly may also include a drive unit 240, two intermediate rods 250, and two hinged sliders 260. The drive unit 240 has a base 242 fixed to the frame 100 and a drive rod 244 that can extend and retract vertically relative to the base 242. The two intermediate rods 250 are both connected to the ends of the drive rods 244. The hinged sliders 260, intermediate rods 250, and connecting rods 230 correspond one-to-one, and each hinged slider 260 has a first rotating part 262 and a second rotating part 264 that can rotate relative to each other. The first rotating part 262 is connected to the intermediate rod 250, and the second rotating part 264 is slidably sleeved on the connecting rod 230. When the drive rod 244 extends downward, the intermediate rod 250 drives the hinge slider 260 to move downward, and the hinge slider 260 drives the connecting rod 230 to rotate downward, thereby causing the gripper 210 to open. When the drive rod 244 retracts upward, the intermediate rod 250 drives the hinge slider 260 to move upward, and the hinge slider 260 drives the connecting rod 230 to rotate upward, thereby causing the gripper 210 to close.

[0039] In this embodiment, the drive unit 240 can be a power cylinder, the seat 242 is a cylinder seat, and the drive rod 244 is a piston rod. The upper end of the seat 242 can be fixed to the top wall of the processing space 140 and extend downwards, while the drive rod 244 can extend and retract vertically. Two intermediate rods 250 are both connected to the ends of the drive rod 244; alternatively, the two intermediate rods 250 can be connected as a single unit and then connected to the ends of the drive rod 244. When the drive rod 244 extends and retracts vertically, it can drive the two intermediate rods 250 to move vertically.

[0040] For one of the gripping components, a hinged slider 260 is connected to the intermediate rod 250. The first rotating part 262 of the hinged slider 260 is connected to the intermediate rod 250, and the second rotating part 264 of the hinged slider 260 is connected to the connecting rod 230. Thus, when the drive rod 244 extends downward, it can drive the hinged slider 260 to move downward, and the hinged slider 260 can provide a vertically downward force to the connecting rod 230. Since one end of the connecting rod 230 is connected to the rotating shaft 220, this vertically downward force can be decomposed into a component force perpendicular to the connecting rod 230 and downward, and a component force along the extension direction of the connecting rod 230. Under the action of the component force perpendicular to the connecting rod 230 and downward, the connecting rod 230 can be made to rotate downward. Furthermore, since the first rotating part 262 and the second rotating part 264 can rotate relative to each other, and the second rotating part 264 is slidably sleeved on the connecting rod 230, the second rotating part 264 can adjust its relative angle with the connecting rod 230 by rotating. The component force along the extension direction of the connecting rod 230 can cause the connecting rod 230 to slide on the second rotating part 264, allowing the structure to move normally and preventing jamming. Conversely, when the drive rod 244 retracts upward, it can cause the connecting rod 230 to rotate upward.

[0041] Similarly, for the other gripping component, when the drive rod 244 extends downward, it causes the link 230 to rotate downward. When the drive rod 244 retracts upward, it causes the link 230 to rotate upward.

[0042] In other words, the drive assembly of this embodiment can cause the two grippers 210 to rotate downward synchronously to open the material pick-up port away from each other by extending and retracting the drive unit 240, and can also cause the two grippers 210 to rotate upward synchronously to close the material pick-up port close to each other.

[0043] In some embodiments, the feed mechanism 300 may further include a support plate 320 and a feed drive motor 330. The support plate 320 is disposed in the machining space 140, and the feed wheel 310 is rotatably disposed below the support plate 320. The feed drive motor 330 is fixed above the support plate 320 and is connected to the feed wheel 310 for transmission to drive the feed wheel 310 to rotate.

[0044] In this embodiment, the support plate 320 can be horizontally arranged within the processing space 140. Two opposing connecting plates 324 are respectively arranged on the lower sides of the support plate 320, and the two ends of the feed wheel 310 are rotatably connected to the two connecting plates 324. The feed drive motor 330 can be fixed to the upper surface of the support plate 320. A reduction mechanism 360 can be provided on the output shaft of the feed drive motor 330. The output end of the reduction mechanism can be connected to the feed wheel 310 through a transmission mechanism 370, transmitting the power of the feed drive motor 330 to the feed wheel 310. The transmission mechanism 370 can take various forms, such as a gear transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism.

[0045] Furthermore, the support plate 320 may also be provided with a connecting hole 322 so that the transmission mechanism 370 can pass through the upper and lower ends of the support plate 320.

[0046] In some embodiments, the feeding mechanism 300 may further include a plurality of limiting shafts 340, one end of each limiting shaft 340 being fixed to the top wall of the processing space 140 and passing through the support plate 320, so that the support plate 320 moves up and down along the limiting shaft 340, thereby causing the feed wheel 310 to move up and down.

[0047] In this embodiment, the first end of each limiting shaft 340 is fixed to the top wall of the processing space 140, and the second end passes through the support plate 320. When the feed wheel 310 comes into contact with the tree, the tree can push the feed wheel 310 upward. This allows the height of the feed wheel 310 to be adjusted at any time according to the size of the tree, so that the feeding mechanism 300 can feed trees of different sizes without jamming.

[0048] Furthermore, the feed mechanism 300 may also include a plurality of elastic elements 350, which correspond one-to-one with a plurality of limiting shafts 340, and each elastic element 350 is sleeved in the section of the limiting shaft 340 located between the support plate 320 and the top wall of the processing space 140, configured to provide downward pressure to the support plate 320.

[0049] In this embodiment, the elastic element 350 can be a compression spring. The compression spring is sleeved on the section of the limiting shaft 340 located between the support plate 320 and the top wall of the processing space 140. When the tree pushes the feed wheel 310 to move upward, the support plate 320 also moves upward, and the distance between the support plate 320 and the top wall of the processing space 140 is shortened. The compression spring is compressed, generating a downward restoring force. This restoring force can make the feed wheel 310 contact the tree tightly, so that when the feed wheel 310 rotates, more friction is converted into a feeding force on the tree.

[0050] In some embodiments, multiple feeding mechanisms 300 are provided, and the multiple feeding mechanisms 300 are arranged sequentially at intervals, so that the multiple feeding mechanisms 300 can act on different positions in the length direction of the tree, resulting in high feeding efficiency.

[0051] In some embodiments, the slicing mechanism 400 may further include a slicing support 420 and two rotating wheels 430. The slicing support 420 is disposed in the processing space 140. The two rotating wheels 430 are respectively disposed on the left and right sides of the slicing support 420. A cutting tool 410 is connected between the two rotating wheels 430. When the two rotating wheels 430 rotate, they drive the cutting tool 410 to rotate in order to slice the wood to be processed.

[0052] In some specific embodiments, the two rotating wheels 430 are connected by a connecting shaft 450 and are rotatably connected to the slicing support 420 respectively. The two ends of the cutter 410 are respectively connected to the two rotating wheels 430. When the two wheels rotate in a cycle, they can drive the cutter 410 to rotate in a cycle around the connecting shaft 450, thus enabling the slicing of trees through the rotation of the cutter 410.

[0053] In some specific embodiments, the cutting tool 410 can also be configured as multiple tools, which can be arranged circumferentially around the connecting shaft 450 to increase the slicing frequency.

[0054] Furthermore, the slicing mechanism 400 may also include a slicing drive motor 440, which is fixed to the slicing bracket 420 and is connected to one of the rotating wheels 430 to drive the rotating wheel 430 to rotate.

[0055] In this embodiment, the slicing drive motor 440 can be disposed on the upper surface of the slicing holder 420. The output shaft of the slicing drive motor 440 can be connected to the connecting shaft 450 via a transmission mechanism 460, transmitting power from the slicing drive motor 440 to the connecting shaft 450, which in turn transmits power to the cutter 410. The transmission mechanism 460 can take various forms, such as a gear transmission mechanism, a belt transmission mechanism, or a chain rotation mechanism.

[0056] This application also provides an excavator that may include the slicing device in any of the above embodiments.

[0057] Specifically, the frame 100 can be mounted on the stick of the excavator via the mounting base 150. The frame 100 is used to push down and adjust the position of trees by moving the stick. In some specific embodiments, the frame 100 can be equipped with a front fork 130 with an arc-shaped push opening to facilitate the contact with the tree and thus push it down.

[0058] After the tree is pushed down, the gripping mechanism 200 lifts the tree into the processing space 140. Specifically, the telescopic rod of the control drive unit 240 extends downward, and the two grippers 210 rotate downward synchronously to open the pick-up port away from each other, aligning the pick-up port with the tree and allowing the tree to enter the pick-up port. The telescopic rod of the control drive unit 240 retracts upward, causing the two grippers 210 to rotate upward synchronously to close the pick-up port together, thus lifting a section of the tree into the processing space 140.

[0059] During slicing, the feed wheel 310 is rotatably positioned below the support plate 320. It rubs against the surface of the tree through rotation, causing the tree to move backward. When the tree reaches the position of the cutter 410 in the slicing mechanism 400, it is sliced. As the feed mechanism 300 continuously feeds, the cutter 410 can slice the tree multiple times at a certain frequency, eliminating the need for manual feeding, making it safe and efficient.
