Technical Field
[0001] This utility model belongs to the technical field of timber collection and stacking equipment, and in particular relates to a high-efficiency timber clamping device for timber collection and stacking. Background Technology
[0002] A log clamp is a mechanical device specifically designed for securing, gripping, or transporting timber and other strip-shaped materials. In the engineering field, log clamps are often used as excavator attachments. They use a hydraulic system to drive the grab bucket to load, unload, and transport materials such as timber, sugarcane, and scrap metal. Its core structure includes the grab bucket, frame, hydraulic valve group, and cylinders. The grab bucket is made of wear-resistant materials, and the hydraulic system provides power and controls gripping and rotation. Based on functional differences, engineering log clamps are divided into three types: mechanical, rotary hydraulic, and non-rotary hydraulic. Mechanical clamps rely on the bucket cylinder for drive and do not require additional hydraulic lines. Hydraulic clamps require the addition of valve blocks and pipelines to achieve flexible rotation and high-strength gripping. With its hydraulic power system, an engineering log clamp can quickly grab heavy or irregularly shaped materials in complex environments, making it suitable for forestry, ports, and waste disposal scenarios.
[0003] The current methods for collecting and storing timber in national reserve forests are mainly manual collection and collection using timber clamping devices.
[0004] Manual timber collection and handling has the following disadvantages:
[0005] (1) Manually handling heavy timber can easily cause muscle injury or accidents.
[0006] (2) It relies on manual operation, the handling speed is slow, and it is difficult to meet the needs of large-scale operations.
[0007] (3) Long-term repetitive operations can easily lead to worker fatigue and affect the quality of work.
[0008] (4) Poor environmental adaptability, making it difficult to cope with complex terrains such as steep slopes and muddy areas.
[0009] Existing log clamping machines mostly have a four- or five-tooth structure at the bottom of the clamping head, which has the following disadvantages:
[0010] (1) The large number of clamping teeth leads to a complex structure and high manufacturing and maintenance costs;
[0011] (2) The chuck is heavy, the equipment consumes a lot of energy, and the gripping frequency is limited;
[0012] (3) Lacking efficient anti-slip design, the wood is easy to slide.
[0013] Therefore, there is a need for a high-efficiency log clamping device for the tidying of timber in national reserve forests to meet the requirements of tidying timber in national reserve forests. Utility Model Content
[0014] In view of the above-mentioned problems in the prior art, the present invention aims to provide a high-efficiency timber clamping device for timber collection and stacking, which solves the problem that the existing timber collection and stacking methods for national reserve forests are not suitable for the timber collection and stacking needs of national reserve forests.
[0015] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0016] A high-efficiency timber clamping device for collecting and stacking timber is provided, comprising a top base, a rotating disk disposed below the top base, a cycloidal hydraulic motor disposed on the top base for driving the rotating disk to rotate around its own axis, and a clamping structure disposed below the rotating disk; the clamping structure includes a connecting base, on which a first clamping jaw and a second clamping jaw are symmetrically disposed, the tops of the first clamping jaw and the second clamping jaw are hinged to the connecting base via a connecting shaft, and each of the first clamping jaw and the second clamping jaw is provided with a hydraulic drive component, the two hydraulic drive components being used to drive the first clamping jaw and the second clamping jaw to rotate around the hinge connection; the bottom of the first clamping jaw and the second clamping jaw are provided with multiple clamping teeth, and each clamping tooth is fixedly connected with an anti-slip sleeve.
[0017] This utility model discloses a high-efficiency wood clamping device for collecting and stacking timber. By providing anti-slip sleeves on the teeth of the first and second clamping claws, the friction force on the wood is increased, making it less likely for the wood to roll off, thus improving the gripping efficiency.
[0018] Furthermore, as a specific arrangement of the connecting seat, the connecting seat includes a first fixed seat and a second fixed seat symmetrically arranged on the left and right sides, with two connecting shafts disposed between the first fixed seat and the second fixed seat; each connecting shaft is horizontally arranged and passes through the first fixed seat and the second fixed seat, and both ends of each connecting shaft are fixedly connected to the outer sidewalls of the first fixed seat and the second fixed seat, respectively; the tops of the first gripper and the second gripper are rotatably connected to the corresponding connecting shaft through bushings. Setting the connecting seat as a first fixed seat and a second fixed seat facilitates the assembly and disassembly of the first gripper and the second gripper, and facilitates subsequent maintenance and repair of the first gripper and the second gripper.
[0019] Furthermore, as a specific arrangement of the hydraulic drive components, each hydraulic drive component includes a hydraulic rod. The piston rod of the hydraulic rod is rotatably connected to the shaft segment of the connecting shaft via a bushed clevis. The tail end of the hydraulic rod is hinged to either the first or second gripper. A hydraulic cylinder valve is provided on the hydraulic rod. By simultaneously controlling the operating state of the two hydraulic cylinder valves, the two hydraulic rods can be synchronously operated to control the rotation of the first and second grippers, thereby achieving the clamping of the wood.
[0020] Furthermore, as a specific arrangement of the first gripper, the first gripper includes three first gripper arms evenly spaced along the length of the connecting shaft. The tops of the three first gripper arms are rotatably connected to the corresponding connecting shafts through the bushings. Each first gripper arm has a gripping tooth at its bottom. A first fixing plate is laterally connected to the outer wall of the three first gripper arms. The tail end of the hydraulic rod on the first gripper is hinged to the first fixing plate or the inner wall of the first gripper arm.
[0021] Furthermore, as a specific arrangement of the second gripper, the second gripper includes two second gripper arms evenly spaced along the length of the connecting shaft. The tops of the two second gripper arms are rotatably connected to the corresponding connecting shaft through the bushing. Each second gripper arm has a gripping tooth at its bottom. A second fixing plate is laterally connected to the outer wall of the two second gripper arms. The tail end of the hydraulic rod on the second gripper is hinged to the second fixing plate or the inner wall of the second gripper arm.
[0022] The beneficial effects of the above technical solution are as follows: the structure of the two- or three-jaw arms at the bottom of the first and second jaws is simpler than the traditional four- or five-jaw arm structure, reducing manufacturing and maintenance costs. Furthermore, the reduction in the number of jaw arms can reduce the overall weight of the clamping structure, making it easier to drive during operation and reducing the energy consumption and load required by the equipment.
[0023] Furthermore, as a specific arrangement of the anti-slip sleeve, each of the clamping teeth has a wedge-shaped structure, and multiple anti-slip strips are protruding laterally on the clamping surface of each anti-slip sleeve. Each anti-slip strip has a rectangular structure, and the multiple anti-slip strips are evenly spaced in the vertical direction. The multiple anti-slip strips on the anti-slip sleeve increase the friction against the wood, making it less likely for the wood to roll off.
[0024] Furthermore, both the first and second fixing seats have a hollowed-out center section. This design reduces the overall weight of the connecting seat and facilitates control.
[0025] The beneficial effects of this utility model are as follows:
[0026] This utility model discloses a high-efficiency wood clamping device for gathering and stacking timber. By specifically setting the number of claw arms of the first and second claws, its structure is simplified, reducing manufacturing and maintenance costs. It also reduces the overall weight of the clamping structure, lowering energy consumption and load during operation. Two hydraulic rods operate synchronously to control the rotation of one end of the first and second claws, causing the bottom teeth to clamp the timber. Anti-slip sleeves abut against the sides of the timber to prevent slippage, thereby improving clamping efficiency. Attached Figure Description

[0031] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.
[0032] like Figures 1-3 As shown, this utility model provides a high-efficiency wood clamping device for collecting and organizing timber. It includes a top base 1, with a rotating disk 2 positioned below the top base 1. A cycloidal hydraulic motor 3 is mounted on the top base 1 to drive the rotating disk 2 to rotate around its own axis. A clamping structure is positioned below the rotating disk 2. The clamping structure includes a connecting base 4, on which first grippers 5 and second grippers 6 are symmetrically arranged. The tops of both first grippers 5 and second grippers 6 are hinged to the connecting base 4 via a connecting shaft 7. Each of the first grippers 5 and second grippers 6 is equipped with a hydraulic drive component 8, which respectively drives the first grippers 5 and second grippers 6 to rotate around the hinge connection. Multiple gripping teeth 9 are provided at the bottom of both first grippers 5 and second grippers 6, and an anti-slip sleeve 10 is fixedly connected to each gripping tooth 9. The anti-slip sleeve 10 increases the friction on the wood, making it less likely to roll off and improving the gripping efficiency.
[0033] Specifically, as one configuration of the anti-slip sleeve 10, each of the clamping teeth 9 has a wedge-shaped structure, and multiple anti-slip strips 11 are protruding laterally on the clamping surface of each anti-slip sleeve 10. Each anti-slip strip 11 has a rectangular structure, and the multiple anti-slip strips 11 are evenly spaced in the vertical direction. The multiple anti-slip strips 11 on the anti-slip sleeve 10 increase the friction against the wood, making it less likely for the wood to roll off.
[0034] Specifically, as one configuration of the connecting seat 4, the connecting seat 4 includes a first fixed seat 41 and a second fixed seat 42 symmetrically arranged on the left and right sides, with two connecting shafts 7 disposed between the first fixed seat 41 and the second fixed seat 42; each connecting shaft 7 is horizontally arranged and passes through the first fixed seat 41 and the second fixed seat 42, and both ends of each connecting shaft 7 are fixedly connected to the outer sidewalls of the first fixed seat 41 and the second fixed seat 42 respectively; the tops of the first gripper 5 and the second gripper 6 are rotatably connected to the corresponding connecting shaft 7 through bushings. Setting the connecting seat 4 as a first fixed seat 41 and a second fixed seat 42 facilitates the assembly and disassembly of the first gripper 5 and the second gripper 6, and facilitates subsequent maintenance and repair of the first gripper 5 and the second gripper 6. The middle parts of the first fixed seat 41 and the second fixed seat 42 are both hollowed out. The above configuration can reduce the overall weight of the connecting seat 4 and facilitate control.
[0035] As one specific configuration of the hydraulic drive component 8, each hydraulic drive component 8 includes a hydraulic rod 81. The piston rod of the hydraulic rod 81 is rotatably connected to the shaft segment of the connecting shaft 7 via a bushed clevis. The tail end of the hydraulic rod 81 is hinged to either the first gripper 5 or the second gripper 6. A hydraulic cylinder valve 82 is provided on the hydraulic rod 81. By simultaneously controlling the operating state of the two hydraulic cylinder valves 82, the two hydraulic rods 81 can be synchronously operated to control the rotation of the top ends of the first gripper 5 and the second gripper 6, thereby achieving the clamping of the wood.
[0036] As a specific arrangement of the first gripper 5 and the second gripper 6, the first gripper 5 includes three first gripper arms 51 evenly spaced along the length of the connecting shaft 7. The tops of the three first gripper arms 51 are rotatably connected to the corresponding connecting shaft 7 through the bushing. Each first gripper arm 51 has a gripping tooth 9 at its bottom. A first fixing plate 53 is laterally connected to the outer wall of the three first gripper arms 51. The tail end of the hydraulic rod 81 on the first gripper 5 is hinged to the first fixing plate 53 or the inner wall of the first gripper arm 51.
[0037] The second gripper 6 includes two evenly spaced second claw arms 61 along the length of the connecting shaft 7. The tops of the two second claw arms 61 are rotatably connected to the corresponding connecting shaft 7 via bushings. Each second claw arm 61 has a gripping tooth 9 at its bottom. A second fixing plate 62 is laterally connected to the outer wall of the two second claw arms 61. The tail end of the hydraulic rod 81 on the second gripper 6 is hinged to the second fixing plate 62 or the inner wall of the second claw arm 61. The beneficial effects of the above technical solution are: the structure of the two- or three-claw arms at the bottom of the first gripper 5 and the second gripper 6 is simpler than the traditional four- or five-claw arm structure, reducing manufacturing and maintenance costs. Furthermore, the reduction in the number of claw arms reduces the overall weight of the clamping structure, making it easier to drive during operation and reducing the energy consumption and load required by the equipment.
[0038] When clamping solid wood, the top seat 1 and clamping structure are moved by the excavator control. When the first jaw 5 and the second jaw 6 are aligned with the position of the wood to be clamped, the two hydraulic rods 81 are activated. The piston rods of the hydraulic rods 81 extend and drive the first jaw 5 and the second jaw 6 to rotate around the connecting shaft 7, so that the first jaw 5 and the second jaw 6 move closer to each other to grip the side of the wood. The hydraulic fluid is controlled by the hydraulic cylinder valve 82 to realize the extension and retraction of the piston rods of the hydraulic rods 81. When the wood is clamped, the anti-slip strips 11 on the sides of the multiple anti-slip sleeves 10 contact the surface of the wood, increasing the friction on the wood and making it less likely for the wood to roll off.
[0039] In summary, this utility model provides a high-efficiency wood clamping device for collecting and stacking timber. By specifically setting the number of claw arms of the first claw 5 and the second claw 6, its structure is simplified, reducing manufacturing and maintenance costs. It also reduces the overall weight of the clamping structure, lowering energy consumption and load during operation. The synchronous operation of two hydraulic rods 81 controls the rotation of one end of the first claw 5 and the second claw 6, causing the bottom teeth 9 to clamp the timber. The anti-slip sleeve 10 abuts against the side of the timber to prevent slippage, thereby improving clamping efficiency.
