Description

Technical Field

[0001] The utility model belongs to the technical field of waste material recycling, and particularly relates to a tool for disassembling old wooden pallets. Background Art

[0002] Wooden pallets, also known as wooden pallets, are widely used in the transportation and outer packaging of products in logistics, mechanical electronics, ceramic building materials, hardware and electrical appliances, precision instruments and other industries.

[0003] For companies that consume a large amount of wooden pallets, recycling a certain amount of old wooden pallets from the market for reuse will reduce the company's packaging and transportation costs. However, the recycled old wooden pallets come in many sizes and cannot be used directly. When they are reused, they need to be disassembled and the disassembled square timbers need to be reprocessed before they can be used. For solid wood pallets, they are mainly composed of square timbers fixed together. When the weight and volume of the packaged products are large, the size and weight of the square timbers are large, and the square timbers need to be connected by bolts of a certain diameter. During disassembly, the connecting bolts need to be removed one by one, but because they are old wooden pallets, it is easy for the bolts to rust, strip, and other situations that are difficult to disassemble, so disassembly is more difficult. Moreover, since the materials, sizes, and positions of the fixing bolts of the recycled old wooden pallets are different, the difficulty of disassembly is further increased, resulting in low efficiency, time-consuming and labor-intensive disassembly of recycled old wooden pallets, and it is also unable to meet the needs of safe production.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0026] Example 1: Figure 1 、 2 As shown, a tool for dismantling old wooden pallets comprises a hydraulic pump station 1, a hydraulic cylinder 3, a movable blade 4, a fixed blade 5, and a fixed block 6. The hydraulic pump station 1 is connected to the hydraulic cylinder 3, providing hydraulic oil for its extension and retraction and receiving return oil. The hydraulic cylinder 3 is mounted horizontally, with its cylinder body mounted on a cylinder base 2, which is fixed to a fixed platform 8. The fixed platform 8 can be the ground, a steel plate fixed to the ground, or a steel table surface above the ground, as long as it provides a horizontal surface for the hydraulic cylinder 3 and fixed blade 5 to be mounted. For example, in this embodiment, the fixed platform 8 is a steel plate fixed to the ground, and the cylinder base 2 is welded to the steel plate. A tool serving as the movable blade 4 is welded to the end of the piston rod of the hydraulic cylinder 3. The upper surface of the blade edge at the front end of the movable blade 4 is flat, and the lower surface is inclined. A fixed blade 5 is mounted on the fixed platform 8, opposite the movable blade 4. The rear end of the fixed blade 5 is welded to a fixed block 6, which is fixed to the fixed platform 8. Similar to the blade structure of the movable blade 4, the front end of the fixed blade 5 has a flat upper surface and an inclined lower surface. The blade of the fixed blade 5 and the blade of the movable blade 4 are at the same height and are positioned opposite each other. As the piston rod of the hydraulic cylinder 3 extends, the movable blade 4 moves toward the fixed blade 5, shearing the bolts on the old wooden support between them.

[0027] Furthermore, the hydraulic cylinder 3 is rotatably mounted on the cylinder base 2. The cylinder base 2 comprises a left and a right base, each of which is provided with an axial hole. A rotating shaft is provided on either side of the cylinder body of the hydraulic cylinder 3, which is rotatably supported in the corresponding axial hole, thereby achieving a rotatable connection of the hydraulic cylinder 3. This rotatable connection facilitates adjustment of the hydraulic cylinder 3's posture to a horizontal position. Furthermore, the front end of the hydraulic cylinder 3 can be lifted, providing sufficient operating space for easily replacing or repairing the movable blade.

[0028] Furthermore, due to the rotational connection of the hydraulic cylinder 3 , its front end requires certain support, so a cushion block 7 is further provided at the front end of the hydraulic cylinder 3 to support the hydraulic cylinder 3 .

[0029] like Figure 3 As shown, the disassembly tool of the utility model is used to Figure 4 When disassembling the old wooden support 9 shown, the position where the old wooden support 9 needs to be disassembled is placed on the side of the fixed knife 5, so that the edge of the blade of the fixed knife 5 is between the upper square wood 901 and the lower square wood 903, and is aligned with the bolt 902 at the disassembly position. When judging whether the fixed knife 5 is aligned with the bolt 902, the sink groove 904 on the old wooden support 9 can be used as a basis for judgment, because the bolt 902 is installed in the sink groove hole. After the old wooden support 9 is placed, the hydraulic cylinder 3 is started, and the piston rod drives the movable knife 4 to extend and move toward the fixed knife 5, inserting it between the upper square wood 901 and the lower square wood 903 of the old wooden support 9, cooperating with the fixed knife 5 to shear the bolt 902, and shearing the bolt 902.

[0030] According to the above method, the bolts 902 connecting the upper square timber 901 and the lower square timber 903 on the old wooden support 9 are cut off one by one. The bolts 902 after the shearing can fall out from the square timber by knocking.

[0031] It should be noted that the upper surface of the blade of the movable knife 4 and the fixed knife 5 is flat and the lower surface is inclined, so that they can be better inserted between the upper square timber 901 and the lower square timber 903 during the shearing process, and as the insertion depth increases, the inclined surface is used to press down the lower square timber 903, which is conducive to the disassembly of the upper and lower square timbers.

[0032] In addition, in order to adapt to the dismantling of old wooden pallets of more sizes, the movable knife 4 and the fixed knife 5 have a certain height. In this way, when dismantling old wooden pallets 9 of some specifications, the four corners of the old wooden pallet 9 need to be padded. Therefore, several movable pads need to be set up and used according to actual conditions.

[0033] The old wooden pallet disassembly method of this embodiment can significantly improve the disassembly efficiency, shortening the disassembly time of the old wooden pallet from the original 6-10 minutes to 2-4 minutes, effectively reducing the work intensity, improving work efficiency, ensuring operation safety, and increasing the utilization rate of the old wooden pallet.

[0034] Example 2: The difference between this example and Example 1 is that Figure 5 、 6As shown, a guide frame 10 is provided on each side of the hydraulic cylinder 3. The guide frames 10 are fixed to the fixed platform 8 and are located on either side of the piston rod's telescopic range. The distance between the two guide frames 10 is slightly larger than the width of the movable blade 4 and slightly larger than the diameter of the piston rod of the hydraulic cylinder 3. Furthermore, the top of the guide frame 10 is located between the upper and lower edges of the movable blade 4, thereby preventing the movable blade 4 from tilting left or right during disassembly.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Those skilled in the art should understand that the specific implementation methods of the present invention can be modified or replaced with equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
