DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example 1.

[0025] like Figure 1-7As shown, the wood splitter with a cutter head lifting device described in this embodiment includes a workbench 1, and a power device 2, an oil circuit control device 3, a wood splitting cylinder 4 and a cutter head assembly 5 all arranged on the workbench 1. The workbench 1 is also provided with a first driving cylinder 10 connected to the oil circuit control device 3. The cutter head assembly 5 is arranged at the power output end of the first driving cylinder 10 and is configured to be able to rise and fall relative to the workbench 1 under the drive of the first driving cylinder 10; the power device 2 is used to provide power for the oil circuit control device 3, and the oil circuit control device 3 provides the first driving cylinder 10 and the wood splitting cylinder 4 with the pressure oil required for work through valve switching control; the power output end of the wood splitting cylinder 4 is provided with a push plate 41 arranged opposite to the cutter head assembly 5, and the cutter head assembly 5 is a cross structure composed of a vertical blade 51 and a horizontal blade 52, and the horizontal blade 52 is arranged parallel to the table top of the workbench 1, and the plane where the cutting edge of the horizontal blade 52 is located and the plane where the bottom surface of the horizontal blade 52 is located are located in the same horizontal plane.

[0026] like Figure 1 and Figure 6 As shown, the wood splitter of this embodiment is mainly composed of key components such as a workbench 1, a power device 2, an oil circuit control device 3, a wood splitting cylinder 4, a cutter head assembly 5 and a first driving cylinder 10, wherein the workbench 1 serves as the basis of the entire equipment and provides a stable support platform, the power device 2 generally includes one or more engines, and a gear pump and a coupling connected thereto, etc., for providing the necessary power for the entire wood splitter, and the oil circuit control device 3 is installed on the workbench 1, and is responsible for controlling and regulating the oil flow to ensure that the pressure oil can be distributed to each actuator as needed to drive the wood splitting cylinder 4 and the first driving cylinder 10.

[0027] When working, Figure 3 and Figure 4As shown, the operator places the wood to be chopped on the workbench 1, starts the power device 2, and the oil circuit control device 3 starts to work, providing pressure oil to the first driving cylinder 10 and the wood splitting cylinder 4. The first driving cylinder 10 receives the pressure oil through the oil circuit control device 3 to realize the lifting action of the cutter head assembly 5, wherein the cutter head assembly 5 is composed of a vertical blade 51 and a horizontal blade 52, forming a cross structure, the vertical blade 51 is fixed to the power output end of the first driving cylinder 10, and the horizontal blade 52 is arranged parallel to the table top of the workbench 1, and its cutting edge is located at the same horizontal plane as the bottom surface, so as to facilitate accurate chopping. In this way, the operator The first driving cylinder 10 is precisely controlled by the oil circuit control device 3, so that the vertical blade 51 rises or falls to an appropriate position according to the diameter of the wood and the chopping requirements. Then, the wood splitting cylinder 4 acts on the push plate 41 to steadily push the wood toward the cutting edge of the cutter head assembly 5. Under the coordinated action of the vertical blade 51 and the horizontal blade 52, the wood is accurately split into four. After the chopping operation is completed, the oil circuit control device 3 cuts off the pressure oil supply, and the cutter head assembly 5 and the push plate 41 immediately return to the initial state to prepare for the next round of chopping operation. The whole process is smooth and efficient, which significantly improves the production efficiency and safety of the chopping operation.

[0028] In addition, in this embodiment, Figure 1 and Figure 2 As shown, the cutting edge of the horizontal blade 52 and its bottom surface are located at the same horizontal height. This structural layout allows the cutting edge of the horizontal blade 52 to naturally form an upward inclined slope. When the horizontal blade 52 does not need to participate in the chopping action, it can fit tightly with the table surface of the workbench 1 under the control of the first driving cylinder 10. At this time, the cutting edge slope of the horizontal blade 52 acts as an efficient guiding tool, which can smoothly guide the split wood and prevent the wood from getting stuck or blocked. This design not only optimizes the chopping process, but also improves the safety of the operation.

[0029] In some embodiments, Figure 1 and Figure 3 As shown, in order to improve the stability of the blade, the workbench 1 is provided with a guide groove 6 adapted to the vertical blade 51, and a stop member 61 is provided in the guide groove 6 to abut against the back of the vertical blade 51; guide wedges 53 are provided on both sides of the part of the vertical blade 51 extending out of the workbench 1 surface, and the guide wedges 53 extend outward and exceed the edge of the back of the vertical blade 51 to form a positioning groove 54, and the stop member 61 is partially placed in the positioning groove 54 and in contact with the back of the vertical blade 51.

[0030] In the present embodiment, a stop member 61 is constructed inside the guide groove 6 (generally fixedly connected by bolts), and its function is to closely abut against the back of the vertical blade 51, thereby providing stable support for the cutter head assembly 5 during the chopping process and preventing it from moving or vibrating under high pressure. In addition, guide wedges 53 are installed on both sides of the part of the vertical blade 51 extending out of the table top of the workbench 1. These wedges extend outward, beyond the edge of the back of the vertical blade 51, and form a positioning groove 54. In the present embodiment, the thickness of the stop member 61 is adapted to the positioning groove 54, and a part of the stop member 61 is just placed in the positioning groove 54 and contacts the back of the vertical blade 51. This structural design not only ensures the stability and accurate alignment of the vertical blade 51 when adjusting its upper and lower positions, but also prevents any possible swinging or deviation of the entire cutter head assembly 5 during the chopping process, thereby improving the efficiency and safety of chopping.

[0031] In some embodiments, Figure 1 As shown, in order to facilitate the adjustment and maintenance of the blade, a lifting lug 55 is provided on the top of the vertical blade 51. In this embodiment, the lifting lug 55 can be used as a hanging point. When the cutter head assembly 5 needs to be inspected, cleaned or replaced, the cutter head assembly 5 can be lifted from the workbench 1 using a lifting device or a manual tool without directly touching the sharp blade with hands, thereby reducing safety risks during work.

[0032] In some embodiments, Figure 4 and Figure 6 As shown, in order to ensure structural stability, a first mounting seat 11 and a second mounting seat 12 are spaced apart at the bottom of the workbench 1, the first driving cylinder 10 is connected to the first mounting seat 11 through a hinge, a driven bent plate 121 is hinged on the second mounting seat 12, one end of the driven bent plate 121 is hinged to the power output end of the first driving cylinder 10, and a driving pin 122 is extended from the other end, and an oblong hole 511 is provided at the lower portion of the vertical blade 51, and the oblong hole 511 is designed to cooperate with the driving pin 122.

[0033] In this embodiment, the first mounting seat 11 and the second mounting seat 12 provide stable mounting points. When the position of the cutter head assembly 5 needs to be adjusted, the power output end of the first driving cylinder 10 will drive the driven bent plate 121 to rotate relative to the second mounting seat 12. This action accurately guides the vertical blade 51 to move along the guide groove 6 through the coordinated action of the driving pin 122 and the oblong hole 511 at the bottom of the vertical blade 51, thereby achieving precise position adjustment of the cutter head assembly 5.

[0034] In some embodiments, Figure 7As shown, in order to reduce the direct contact between the operator and the moving parts, a shield structure 7 is also provided at the bottom of the workbench 1, and the shield structure 7 is used to cover and protect the first driving cylinder 10, the driven bending plate 121 and the part of the vertical blade 51 extending outside the bottom of the workbench 1.

[0035] In specific implementation, the shield structure 7 is fixedly installed at the bottom of the workbench 1 by bolts. During the operation of the wood splitter, the shield structure 7 prevents any object or operator's hand from accidentally entering the moving parts area, greatly reducing the safety risk during operation.

[0036] In some embodiments, Figure 1 , Figure 3 and Figure 4 As shown, the workbench 1 is also provided with a lifting assembly 8, and the lifting assembly 8 includes a second driving cylinder 81, a lifting bracket 82 and a support rod member 83. The workbench 1 is provided with a third mounting seat 13 hinged to the second driving cylinder 81, a fourth mounting seat 14 hinged to the second lifting bracket 82 and a fifth mounting seat 15 hinged to the support rod member 83. The power output end of the second driving cylinder 81 is hingedly connected to the free end of the support rod member 83. The free end of the support rod member 83 is equipped with a roller assembly 84. The support rod member 83 is abutted against the back of the lifting bracket 82 through the roller assembly 84 to drive the lifting bracket 82 to place the wood between the push plate 41 and the tool head assembly 5.

[0037] During specific implementation, the operator places the wood on the lifting bracket 82 and starts the wood splitter. Under the control of the oil circuit control device 3, the second driving cylinder 81 receives the pressure oil and starts working. Its power output end pushes the free end of the support rod member 83. The free end of the support rod member 83 is equipped with a roller assembly 84. As the support rod member 83 pushes, the roller assembly abuts against the back of the lifting bracket 82 and drives the lifting bracket 82 to rise. When the lifting bracket 82 rises, it will carry the wood to between the push plate 41 and the cutter head assembly 5, thereby realizing automatic lifting and precise placement of the wood. This saves the operator from having to manually carry and position the wood, greatly reducing labor intensity.

[0038] In some embodiments, Figure 5 and Figure 6 As shown, in order to facilitate movement, the lifting bracket 82 and the fourth mounting seat 14 are both provided with fixing ears, and an axial hole 16 is provided on the fixing ear, and the axial holes 16 of the two fixing ears correspond to each other and are coaxial when the lifting bracket 82 moves to a position perpendicular to the workbench 1. In this way, when the wood splitter needs to be transported, the lifting bracket 82 can be turned up, and after the axial pin 100 passes through the axial hole 16, it is fixed with an O-ring. After the fixing is completed, the operator can safely move the wood splitter to the designated working position.

[0039] In some embodiments, Figure 1 As shown, in order to improve safety, the workbench 1 is also provided with a rear stopper 9 for receiving the chopped wood, and a plurality of guardrail frames 91 are also installed around the rear stopper 9. In this way, as the chopping action is performed, the wood is split by the cutter head assembly 5, and the chopped wood is received by the rear stopper 9. At the same time, the guardrail frames 91 can prevent the wood from rolling or moving out of the working area, thereby keeping the working area clean and tidy, and helping to maintain a good working environment.

[0040] In some embodiments, Figure 1 and Figure 6 As shown, in order to facilitate positioning and adjustment, the workbench 1 is provided with a towing rod 92 and a supporting leg 93 at the front, and a traveling wheel 94 at the rear. In this way, the design of the towing rod 92 allows the wood splitter to be easily moved to a designated position by traction, while the supporting leg 93 can provide additional support and stability after the equipment is in place, facilitating the rapid positioning and placement of the equipment, and the design of the traveling wheel 94 provides mobility for the wood splitter.

[0041] The wood splitter with a cutter head lift provided in this embodiment allows the operator to easily adjust the height of the cutter head to adapt to wood of different diameters by introducing a cutter head lift mechanism and a lifting assembly, thereby ensuring the precise positioning and effective chopping of wood, making the entire chopping process more coherent and efficient, that is, the operator can focus on the placement of the wood and the chopping strategy rather than on tedious physical labor, and significantly improving the safety of the operation.
