Description

Technical Field

[0001] The utility model relates to the technical field of firewood chopping tools, in particular to a firewood chopping tool capable of adjusting multiple gears. Background Art

[0002] In traditional wood chopping operations, using an axe is the most common method. However, this method has many problems, making the wood chopping process both laborious and dangerous. The specific problems are as follows:

[0003] 1. Safety Risk: When swinging an axe to chop wood, due to its heavy weight and the high speed required, it is easy for the operator to mishandle the axe, causing it to deviate from its intended trajectory or even fly out of the hand. This not only poses a direct danger to the operator but also may injure surrounding personnel, posing a significant safety hazard.

[0004] 2. Effortless and inefficient operation: Chopping wood with an axe requires considerable physical effort, especially for larger or harder logs, which require repeated, forceful chopping. Prolonged, high-intensity operation can easily lead to operator fatigue and reduce chopping efficiency. Furthermore, the axe requires a large space to swing, which can restrict operation in confined environments, further impacting chopping efficiency.

[0005] 3. Requires High Skill: When chopping wood with an axe, the operator typically needs to hold the wood with one hand while swinging the axe with the other. This operation not only requires high coordination and skill, but also places the hand very close to the chopping area while holding the wood, making accidental injury very likely. For inexperienced users, this operation is particularly dangerous and challenging.

[0006] 4. Unstable firewood: During axe chopping, firewood is often difficult to secure effectively, making it prone to sliding or tipping over during chopping, resulting in poor chopping results. Unstable firewood not only affects chopping efficiency but also increases the difficulty and risk of the operation. Without effective means of securing the firewood, the operator must constantly adjust its position, further increasing the time and effort required.

[0007] In summary, traditional firewood splitting tools have many deficiencies during use, and there is an urgent need for a safe, convenient and efficient firewood splitting tool to solve the above problems. Utility Model Content

[0029] Through the matching combination design of the guide column, base, lifting sleeve and cutter of this solution, the wood chopping tool is more stable during use. The cutter is assembled to the lifting sleeve in a hinged manner and will not fly out, and the movement trajectory is relatively fixed. When chopping wood, there is no need to swing a heavy axe, which avoids the risk of the axe flying out or deviating from the trajectory, greatly improving the safety of operation.

[0030] 2. Reduce operating intensity and improve chopping efficiency:

[0031] Through the design of the mechanical structure, the movement of the cutter uses the principle of leverage to act on the firewood. The operator no longer needs to expend a lot of physical strength to swing the axe, but can complete the task of chopping wood through simple operations, which significantly reduces physical exertion.

[0032] 3. Easy to use and simple to operate:

[0033] The firewood chopping tool in this solution is well-designed and easy to operate. It requires no special skills and is easy to use, reducing the barrier to entry for even inexperienced users. The tool's movement path is fixed, and the operator only needs to place the firewood in the appropriate position, avoiding the danger of having their hands close to the chopping area. The entire chopping process is more intuitive and safer, greatly reducing the difficulty and technical requirements of operation.

[0034] 4. Strong stability and good firewood chopping effect:

[0035] This solution achieves a stable combination of the guide column and base by designing diagonal braces or connecting components. Furthermore, the longitudinal and transverse pads provide stable support points for the firewood being handled, ensuring excellent stability during use. Firewood is securely positioned within the fixed area of ​​the firewood chopping tool, preventing it from sliding or tipping over, ensuring precise and effective chopping with every strike.

[0036] 5. Adjustability and versatility: The tool height can be adjusted with the lifting sleeve, and the movable handle allows for optimal adjustment of the force arm to accommodate firewood of varying sizes and volumes, enhancing the tool's adjustability and applicability. The tool, along with its fixed and movable handles, can be quickly removed from the lifting sleeve. Once removed, the tool can be used flexibly for other purposes.

DETAILED DESCRIPTION

[0054] 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.

[0055] See also Figure 1-13 A multi-gear adjustable wood chopping tool includes a base 1, a guide column 2, a lifting sleeve 3, a locking piece, and a cutter 5. The bottom of the guide column 2 is fixedly combined with the base 1, the guide column 2 and the base 1 are vertically distributed, the lifting sleeve 3 is slidably installed on the guide column 2, the locking piece is assembled on the lifting sleeve 3 and is used to position the lifting sleeve 3 on the guide column 2, the inner end of the cutter 5 is hinged to the lifting sleeve 3, and the outer end of the cutter 5 is fixedly connected to a fixed handle 51.

[0056] The base 1 and guide post 2 are made of different types of square tubes, offering lightweight yet stable structural strength, ensuring convenient assembly, disassembly, and transport of the firewood chopping tool, as well as stable chopping operation. The lifting sleeve 3 is also made of square tubes, with its inner wall slidingly connected to the outer wall of the guide post 2.

[0057] Base 1 is assembled horizontally, its primary function being to ensure the stability of guide post 2 welded thereto while providing stable support for the wood 8 to be split. Guide post 2 allows for height adjustment of lifting sleeve 3, which is locked to a specific height position on guide post 2 via a latch, allowing adjustment of the height of cutter 5.

[0058] The assembly height of the cutter 5 is adjusted according to the size of the firewood 8 to be processed, ensuring that when the cutter 5 is tilted about its hinge point with the lifting sleeve 3, it can chop the firewood 8 with minimal effort. Because the cutter 5 is hingedly mounted to the lifting sleeve 3, compared to traditional axes, the cutter 5 will not accidentally fly out during the chopping process, ensuring safety. Moreover, the cutter 5 can be flipped up and down in conjunction with the fixed handle 51 to chop the firewood 8 below. This method does not require extensive chopping skills, making it easy to use and reducing the barrier to entry.

[0059] The fixed handle 51 is made of a metal round tube and is welded to the outer end of the cutter 5. The length of the fixed handle 51 is set between 1 and 2.5 times the length of the cutter 5. The longer fixed handle 51 can reduce the force required by the lever principle when chopping wood, achieving the design purpose of labor-saving chopping wood and effectively improving the chopping efficiency.

[0060] In order to ensure that the firewood chopping tool can chop firewood stably and avoid the chopping effect being affected by the shaking of the wood or the firewood chopping tool, the following technical solutions are provided.

[0061] A connecting plate 11 is fixedly connected to the lower surface of the base 1 . The connecting plate 11 is arranged at both ends of the base 1 . A connecting through hole 111 is formed on the connecting plate 11 .

[0062] The connecting plate 11 is made of metal plates cut and drilled, and is fixed to the two ends of the lower surface of the base 1 by welding. The connecting through holes 111 opened thereon can be fixed to a stable base or pedestal by a through-bolt assembly to effectively fix the firewood chopping tool and thereby ensure the stability of the firewood chopping operation.

[0063] In order to ensure that the firewood chopping tool can stably support the firewood 8 of different sizes to be processed, the following technical solutions are provided.

[0064] Several groups of transverse pads 12 arranged side by side are fixedly connected to the upper surface of the base 1 , and several groups of longitudinal pads 21 arranged side by side are fixedly connected to the bottom of the guide column 2 .

[0065] The transverse pads 12 and longitudinal pads 21 can be made of angle steel. After the angle steel is cut to a specific length, its side panels are welded to the transverse pads 12 and longitudinal pads 21, respectively. The transverse pads 12 are located near the ends of the base 1 on the guide column 2, while the longitudinal pads 21 are arranged toward the side where the tool 5 is located.

[0066] When processing firewood 8, the bottom of the firewood 8 can be directly supported by the base 1, and the top of the firewood 8 can be pressed by the downward-pressing knife 5 to complete the firewood chopping operation. The bottom of the firewood 8 can also be abutted against the horizontal pad 12 or the vertical pad 21 at a suitable position to provide a stable support point for the firewood 8 and ensure stable chopping operation.

[0067] In order to ensure that the inner end of the tool 5 can be stably assembled on the lifting sleeve 3 in a detachable manner, so as to achieve rapid disassembly and assembly of the tool 5, the following technical solution is provided.

[0068] The outer wall of the lifting sleeve 3 is fixed with two groups of articulated seats 31 arranged side by side. The inner end of the tool 5 is arranged between the two groups of articulated seats 31. The articulated seat 31 and the inner end of the tool 5 are respectively provided with an assembly pin hole A311 and an assembly pin hole a52. The assembly pin hole A311 and the assembly pin hole a52 are equipped with a pin rod bolt part A312.

[0069] The hinged seat 31 and the assembly pin hole A311 opened thereon can ensure the stable assembly of the tool 5 and the assembly pin hole a52 opened thereon. The hinged seat 31 and the tool 5 are assembled through the pin rod bolt part A312 to achieve stable rotation of the inner end of the tool 5 around the hinged seat 31.

[0070] The pin rod bolt member A312 includes a pin rod member with a threaded groove at the end and a matching nut, which can ensure that the tool 5 is flipped up and down around the pin rod bolt member A312. At the same time, the pin rod bolt member is easy to remove to remove the tool 5 and the matching fixed handle 51. The removed tool 5 can be flexibly used for other purposes. After the chopping tool is used, the tool 5 can be removed and stored separately, which can also improve safety.

[0071] In order to ensure that the locking member can be stably assembled on the lifting sleeve 3 and to ensure that the locking member can position the lifting sleeve 3 at a specific position of the guide column 2, the following technical solution is provided.

[0072] The outer wall of the lifting sleeve 3 is fixed with an assembly seat 32, an assembly through hole 321 is opened in the assembly seat 32, the outer end of the assembly through hole 321 is fixed with a limit ring 322, and the guide column 2 is provided with multiple groups of evenly arranged positioning pin holes 22.

[0073] The locking component includes a positioning pin rod 41, a connecting rod 42, a pull ring 43, and a return spring 44. The positioning pin rod 41 is slidably inserted in the assembly through hole 321 and remains nested and inserted with the positioning pin hole 22. The connecting rod 42 is fixed to the outer end of the positioning pin rod 41 and slidably inserted in the limiting ring 322. The pull ring 43 is assembled on the outer end of the connecting rod 42 and arranged on the outside of the assembly seat 32. The return spring 44 is arranged on the periphery of the connecting rod 42. The two ends of the return spring 44 respectively remain in contact with the positioning pin rod 41 and the limiting ring 322.

[0074] The arrangement of the assembly seat 32 and the assembly through hole 321 and the limiting ring 322 therein can ensure that the locking member is stably assembled therein.

[0075] In a natural state, the return spring 44 can drive the positioning pin 41 to extend inward from the assembly through hole 321 and be nested and plugged into the positioning pin hole 22 at the corresponding position, so that the lifting sleeve 3 is positioned and locked by the positioning pin 41.

[0076] A radially distributed assembly channel is provided at the outer end of the connecting rod 42 to ensure that the pull ring 43 is stably assembled therein. At the same time, the pull ring 43 and the limiting ring 322 maintain spatial motion interference, which can effectively prevent the locking member from falling off from the assembly seat 32.

[0077] When assembling the locking part into the assembly seat 32, first put the return spring 44 onto the outer periphery of the connecting rod 42, and insert it into the assembly through hole 321 from the inner cavity of the lifting sleeve 3, and then assemble the pull ring 43 into place to prevent the positioning pin rod 41 and the connecting rod 42 from falling off from the assembly through hole 321.

[0078] When adjusting the height of the lifting sleeve 3, the pull ring 43 can be pulled to drive the connecting rod 42 and the positioning pin rod 41 to slide toward one end of the pull ring 43 to cancel the locking state between the positioning pin rod 41 and the positioning pin hole 22, thereby realizing the lifting and lowering adjustment of the lifting sleeve 3 along the guide column 2.

[0079] When the lifting sleeve 3 and the cutter 5 mounted thereon are in the lower position of the guide column 2, in order to prevent the excessively long fixed handle 51 from colliding with the base or the abutment during the downward tilting process, and at the same time facilitate adjustment of the length of the fixed handle 51 according to the size and volume of the firewood 8 to be processed, the following technical solution is provided.

[0080] The outer periphery of the fixed handle 51 is slidably sleeved with a movable handle 53. The fixed handle 51 is evenly provided with multiple groups of radially distributed adjustment holes 511. The inner end of the movable handle 53 is provided with a positioning hole 531. The positioning hole 531 is equipped with a positioning bolt 54 that is nested and plugged with the corresponding adjustment hole 511.

[0081] The movable handle 53 is also made of round tube. When selecting to assemble the movable handle 53 , the length range of the fixed handle 51 is set between 1 and 1.5 times the length of the tool 5 . The movable handle 53 is the same length as or slightly larger than the fixed handle 51 .

[0082] At least two groups of positioning holes 531 are provided, and the spacing between positioning holes 531 and the spacing between adjustment holes 511 is maintained equal, ensuring that the two groups of positioning holes 531 can be simultaneously arranged relative to two adjacent groups of adjustment holes 511. By locating bolts 54 passing through the positioning holes 531 and the adjustment holes 511 at specific locations, the movable handle 53 and the fixed handle 51 can be fixedly combined and the total length of the handle can be effectively adjusted.

[0083] In order to ensure that the guide column 2 and the base 1 can be fixedly combined in a stable posture and further improve the structural stability of the firewood chopping tool when in use, the following technical solution is provided.

[0084] It also includes an oblique support rod A6. The bottom end of the guide column 2 is fixedly connected to the upper surface of the base 1, and the two ends of the oblique support rod A6 are fixedly connected to the guide column 2 and the base 1 respectively.

[0085] The diagonal support rod A6 is made of a square tube, and its end is cut into a structure that matches the base 1 and the guide column 2. The diagonal support rod A6 is arranged at an angle compared to the guide column 2 and the base 1, and is fixedly connected to the guide column 2 and the base 1 by welding. The bottom end of the guide column 2 is also welded to the base 1. By adding the diagonal support rod A6, the stability of the connection between the guide column 2 and the base 1 can be effectively improved, thereby improving the structural stability of the firewood chopping tool during chopping operations.

[0086] The diagonal bracing rods A6 and the longitudinal pads 21 are respectively arranged on both sides of the guide column 2 , which can prevent the diagonal bracing rods A6 from causing spatial interference with the processed firewood 8 and affecting the stable support of the firewood 8 .

[0087] After the firewood chopping tool is used and the cutter 5 is removed, in order to facilitate the storage, transportation, and taking out of the firewood chopping tool body while ensuring the structural stability of the main structure, the following technical solution is provided.

[0088] The guide column 2 and the base 1 are fixedly combined through a connecting component, which includes an assembly bracket 71, an assembly wing plate 72, and a diagonal support rod B73. The assembly bracket 71 is fixedly connected to the base 1, and the bottom end of the guide column 2 is hinged to the assembly bracket 71. The assembly wing plate 72 includes two groups that are fixedly connected to the guide column 2 and arranged side by side. The two ends of the diagonal support rod B73 are respectively hinged to the assembly wing plate 72 and the assembly bracket 71.

[0089] The assembly bracket 71 is formed by cutting channel steel, or by bending and cutting metal plates, and is fixed to the end of the upper surface of the base 1 by welding.

[0090] The diagonal support rod B73 also adopts a square tube, and its end is cut into an arc shape to avoid spatial and motion interference with the assembly bracket 71 or the guide column 2. The diagonal support rod B73 is arranged at an angle to form a triangular structure with the guide column 2, the assembly bracket 71 or the base 1. It has super structural stability and can ensure the structural stability of the connection between the guide column 2 and the base 1.

[0091] In order to facilitate the disassembly and assembly of the guide column 2, the base 1 and the connecting components and to realize the folding or unfolding of the guide column 2 and the base 1, the following technical solution is provided.

[0092] The assembly bracket 71 and the guide column 2 are respectively provided with an assembly pin hole B711 and an assembly pin hole b23 at the bottom end for maintaining the coaxial arrangement, and the assembly pin hole B711 and the assembly pin hole b23 are equipped with a pin rod bolt component B741; the assembly wing plate 72 and the diagonal support rod B73 are respectively provided with an assembly pin hole C721 and an assembly pin hole c731 at the top end for maintaining the coaxial arrangement, and the assembly pin hole C721 and the assembly pin hole c731 are equipped with a pin rod bolt component C742, and the assembly bracket 71 and the diagonal support rod B73 are respectively provided with an assembly pin hole D712 and an assembly pin hole d732 at the bottom end for maintaining the coaxial arrangement, and the assembly pin hole D712 and the assembly pin hole d732 are equipped with a pin rod bolt component D743.

[0093] When folding the guide column 2, the pin rod bolt member D743 is removed. After the guide column 2 loses the function of the diagonal support rod B73, the guide column 2 is controlled to flip toward the base 1 to a horizontal state around the pin rod bolt member B741, and the diagonal support rod is flipped to a horizontal state around the pin rod bolt member C742 and kept in contact with the guide column 2, thereby realizing the folding of the guide column 2 to reduce the size of the main structure of the firewood chopping tool, making it convenient for storage, transportation, and taking.

[0094] When the main structure of the firewood chopping tool is folded, in order to avoid spatial movement interference between the longitudinal pad 21 and the assembly bracket 71, in the firewood chopping tool with an additional connecting component, the length of the longitudinal pad 21 is smaller, and in the folded state, the longitudinal base 1 can be located on the inner side of the assembly bracket 71 to avoid interference between the two.

[0095] When the guide post 2 is flipped and folded to a horizontal state, the hinge seat 31 on the lifting sleeve 3 is in contact with the upper surface of the base 1 to ensure that the folded guide seat is stably placed on the base 1.
