This is labor-intensive, and the choppers are easily injured. The tools often miss the target, so the efficiency is low. This method is more common in rural areas. The other is to use electric tools such as chainsaws to chop wood. Although the efficiency is improved, the equipment cost is high and the energy consumption is also high.

[0003] With the continuous improvement of living standards, special machines for splitting firewood have emerged to meet people's demand for efficient firewood splitting tools. However, existing firewood splitters generally have the problems of bulky size and inconvenient mobility. In addition, during operation, the impact pressure on the bottom of the firewood splitter when it contacts the ground is large, resulting in a high noise level. This not only affects the operator's experience, but also causes certain interference to the surrounding environment. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 4 As shown, the utility model provides a shock-absorbing wood splitter, including a workbench 1, the four corners of the lower end of the workbench 1 are fixedly connected to support columns 11, the lower ends of the support columns 11 are fixedly connected to shock-absorbing pads 3, a moving mechanism 4 is arranged between the two groups of support columns 11 on the left and right sides of the workbench 1, and a wood splitting mechanism 2 is arranged on the upper end of the workbench 1. By equipping the moving mechanism 4 on the support columns 11, the wood splitter is conveniently moved, and the problem that the traditional wood splitter is bulky and difficult to carry is effectively solved. At the same time, adjustable rollers 45 are provided in the moving mechanism 4, so that it can be raised, so that the shock-absorbing pads 3 at the lower ends of the support columns 11 directly contact the ground. During operation, the shock-absorbing pads 3 effectively absorb the impact from the bottom and reduce noise, thereby improving the user's comfort and experience.

[0023] In a further embodiment, referring to Figure 2-Figure 4 The moving mechanism 4 includes a bidirectional threaded rod 41 and a roller 45. The bidirectional threaded rod 41 is rotatably connected between the two groups of support columns 11 located on the left and right sides of the workbench 1. The front and rear side walls of the bidirectional threaded rod 41 are threadedly connected with threaded blocks 42. The lower end of the threaded block 42 is rotatably connected to a connecting rod 43. The end of the connecting rod 43 away from the threaded block 42 is rotatably connected to a connecting block 46. The side of the connecting block 46 close to the support column 11 is fixedly connected to a slider 44. The end of the slider 44 away from the support column 11 is rotatably connected to the roller 45. A limiting slide groove 12 is provided on the end surface of the support column 11 close to the connecting rod 43. The slider 44 is located inside the limiting slide groove 12 and is slidably connected thereto.

[0024] In this embodiment, the threaded block 42 is driven to move inward by rotating the bidirectional threaded rod 41, and the inward movement of the threaded block 42 drives the connecting rod 43 to move, and the movement of the connecting rod 43 drives the connecting block 46 to move. Since the slider 44 is fixed on one side of the connecting block 46, and the slider 44 slides inside the limiting slide groove 12, the slider 44 can be driven to move upward during the movement of the connecting rod 43, and the upward movement of the slider 44 drives the roller 45 to move upward, so that the roller 45 is away from the ground, and then the shock-absorbing pad 3 at the lower end of the support column 11 is in direct contact with the ground. Therefore, during the operation, the shock-absorbing pad 3 effectively absorbs the impact from the bottom, reduces noise, and thus improves the user's comfort and experience.

[0025] In a further embodiment, referring to Figure 4 The bidirectional threaded rods 41 on the left and right sides of the workbench 1 are connected through a sprocket set 47.

[0026] In this embodiment, the two sets of bidirectional threaded rods 41 are connected to each other by adopting a sprocket group 47 transmission system. When the bidirectional threaded rod 41 on one side rotates, the bidirectional threaded rod 41 on the other side will also rotate synchronously through the action of the sprocket group 47. This design achieves the purpose of synchronously raising the roller 45 away from the ground, ensuring the coordination and consistency of the operation.

[0027] In a further embodiment, referring to Figure 1 The rear ends of the two groups of support columns 11 located at the rear side of the workbench 1 are fixedly connected with a protective cover 5, which is used to protect the sprocket set 47.

[0028] In this embodiment, the utility model is specially provided with a protective cover 5 to provide effective protection for the sprocket assembly 47 to prevent the wood piled above from accidentally falling and hitting the sprocket assembly 47 during the chopping operation, thereby avoiding damage and ensuring the safety and durability of the equipment.

[0029] In a further embodiment, referring to Figure 1 The thread directions of the bidirectional threaded rods 41 on the left and right sides of the workbench 1 are the same.

[0030] In this embodiment, since the thread directions of the two sets of bidirectional threaded rods 41 are the same, the rotation directions of the bidirectional threaded rods 41 are consistent when the bidirectional threaded rods 41 are rotated, thereby ensuring that the rollers 45 are raised synchronously.

[0031] In a further embodiment, referring to Figure 1-Figure 4 The chopping mechanism 2 includes a motor 23 and a processing head 22. The upper end of the workbench 1 is rotatably connected to the rotating shaft 21 through a bearing seat. The right end of the rotating shaft 21 is fixedly connected to the processing head 22. The lower end of the workbench 1 is fixedly connected to the motor 23. The output shaft end of the motor 23 and the rotating shaft 21 are connected through a pulley group 24.

[0032] In this embodiment, the motor 23 is started to drive the output shaft of the motor 23 to rotate. Since the output shaft of the motor 23 is connected to the rotating shaft 21 through the pulley group 24, the rotating shaft 21 is driven to rotate. The rotation of the rotating shaft 21 drives the processing head 22 to rotate. The rotating processing head 22 can achieve the effect of chopping wood.

[0033] The working principle of the present invention is as follows: when working, by pushing the workbench 1, under the action of the roller 45, the workbench 1 can be moved to a suitable position, and then by rotating the two-way threaded rod 41, the threaded block 42 is driven to move inward, the threaded block 42 moves inward to drive the connecting rod 43 to move, and the connecting rod 43 moves to drive the connecting block 46 to move. Since the slider 44 is fixed on one side of the connecting block 46, and the slider 44 is located in the internal sliding groove 12, the connecting rod 43 can drive the slider 44 to move upward during the movement of the connecting rod 43, and the slider 44 moves upward to drive the roller 45 to move. The motor 23 is started to drive the output shaft of the motor 23 to rotate. Since the output shaft of the motor 23 is connected to the rotating shaft 21 through the pulley group 24, the rotating shaft 21 is driven to rotate. The rotation of the rotating shaft 21 drives the processing head 22 to rotate. The rotating processing head 22 can achieve the effect of chopping wood.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
