Description

Technical Field

[0001] The utility model belongs to the technical field of wood processing, and in particular relates to an efficient and stable wood splitter. Background Art

[0002] A wood splitter is a piece of mechanical equipment used for wood processing. Its main function is to split logs or larger wood sections along the grain direction to obtain smaller firewood or wood boards. Its structure usually includes a sturdy frame that provides stable support for the entire device. It also has a power unit. The power source can be electric, hydraulic or gasoline engine driven. When the power unit is started, it will drive the splitting parts such as the chopper or wedge to move. These splitting parts are generally made of high-strength metals such as alloy steel and can withstand huge pressure. When working, the wood is placed in the designated position, and the control device is operated to make the splitting parts insert into the wood with strong force. The wood's own grain and the pressure of the splitting parts are used to split it. It is widely used in forestry, wood processing plants, and some places that require a lot of firewood, such as homes with fireplaces for heating.

[0003] The Chinese patent with the announcement number "CN221659577U" discloses a wood splitter that is easy to operate, which includes a working frame, a sliding groove is provided on one side of the middle part of the bottom surface of the working frame, and a fixed seat is fixedly connected to the other side of the middle part of the bottom surface of the working frame. In the utility model, when the wood splitter is used, one end of the log to be split is placed in the placement groove, and the other end is lifted to slide the whole into the bottom of the working frame, and the electric telescopic rod is activated to drive the limiting pads on both sides to move in opposite directions, so as to clamp the two ends of the log so that it is located in the middle of the bottom surface. At this time, the sliding frame is driven to slide in the sliding groove by activating the hydraulic telescopic rod, thereby driving the wood splitting knife to continuously approach one side of the log. When the log starts to be cut, the electric telescopic rod drives the limiting pad to retract into the storage groove. At this time, the wood splitting knife presses against the log to split it. When the wood splitting knife applies force, the log will be subjected to pressure and eventually split into two halves.

[0004] Although the above-mentioned wood splitter can achieve the effect of wood splitting processing to a certain extent during actual application, it also has obvious shortcomings. During the entire processing process, the wood splitter can only perform a single wood splitting operation. After each wood splitting is completed, it is necessary to manually open the wood splitter, take out the chopped wood, and then put in new wood to be chopped before continuing the wood splitting work. This operation method makes it impossible for the wood splitting process to achieve continuous and uninterrupted production and processing. Since the remaining free time in the wood splitting process cannot be used for pre-loading and unloading processing, the overall operation process is relatively cumbersome and inconvenient, which not only consumes a lot of manpower and time, but also greatly reduces the processing efficiency. In view of this, in order to improve the practicality and production efficiency of the wood splitter, it is necessary to improve and optimize it. Utility Model Content

The side guide rollers 662 on the inner side of the side frame 661 and the inner guide rollers 664 in the square groove 663 of the receiving plate 63 cooperate with each other. On the one hand, they can clamp the wood to adapt to wood of different sizes. On the other hand, they can also assist in guiding the wood, so that the wood can move stably inside the receiving plate 63 and the side frame 661 during the splitting process, ensuring that the wood is quickly and stably cut by the splitting blade 7, thereby improving the working efficiency and processing quality of the equipment.

[0029] refer to Figure 1-Figure 2 The pushing assembly 8 includes a fixed seat 81, which is fixedly mounted on the outer upper end of the mounting plate 3 with the first motor 4. The outer side of the fixed seat 81 is fixedly connected to a telescopic cylinder 82, and the output end of the telescopic cylinder 82 passes through the mounting plate 3 and is fixedly mounted with a push plate 83. The push plate 83 is horizontally arranged corresponding to the cutting groove 5.

The push plate 83 connected to its output end can move stably under the push of the telescopic cylinder 82, and the push plate 83 is horizontally arranged corresponding to the cutting groove 5, which can accurately push the wood to the cutting groove 5, ensuring the position accuracy of the wood during the cutting process. During the wood splitting process, the telescopic cylinder 82 can be flexibly adjusted according to the size and processing requirements of different woods, thereby achieving efficient and stable pushing action, thereby improving the working efficiency and processing quality of the wood splitter.

[0030] Principle and advantages of use: Through the positioning mechanism 6, the device can place the wood inside the guide assembly 66 located on the side during actual use. At this time, the driving assembly 65 is started to run, and the operation of the driving assembly 65 can drive the adjustment assembly 64 to be linked, and the linkage of the adjustment assembly 64 will synchronously drive the guide assembly 66 to clamp and position the wood. Then, the telescopic cylinder 82 is started to run, and the telescopic cylinder 82 will push the push plate 83 to move toward the cutting groove 5, and then push the wood to the inside of the cutting groove 5. As the wood moves, the cut wood will pass through the wood splitting blade 7 inside the cutting groove 5 for cutting processing. The wood can be discharged smoothly from the cutting groove 5. During the cutting process, the wood to be cut can be pre-placed inside the guide assembly 66 located on the side and positioned. Then, by starting the first motor 4 to drive the rotating shaft 61 to rotate, the rotation displacement of each guide assembly 66 can be assisted to replace the pre-placed wood. The wood is moved to the pushing assembly 8 for cutting again. It can be seen that the device as a whole can flexibly adjust the rotation of each guide assembly 66 and the cyclic rotation displacement of each receiving plate 63 to realize the pre-placement of wood, so that the cutting process can be carried out continuously and uninterruptedly, which greatly improves the overall production and processing efficiency of the device.

[0031] By arranging the guide assembly 66, the drive assembly 65 and the adjustment assembly 64 to cooperate with each other, the device can place wood on the inner side of each side frame 661 of the guide plate during use. At this time, the second motor 654 is started to run, and the second motor 654 can drive the worm 653 inside the worm plate 651 to rotate. Since the two worms 653 are connected by the connecting shaft 655, they can synchronously drive the two worms 653 to rotate. The rotation of the two worms 653 will synchronously drive the two worm wheels to rotate. The rotation of the two turbines 652 then assists in driving the screw rod 642 inside the slide groove 641 to rotate. It is worth mentioning that the threads at both ends of the screw rod 642 rotate in opposite directions. At this time, the screw rod 642 can drive the slider 643 to slide on the inner side of the slide groove 641, and the sliding of the slider 643 assists in driving the belt The movable side frames 661 are displaced with each other, and the displacement of the side frames 661 can drive the side guide rollers 662 to fit the outer surface of the wood. At this time, the side frames 661 and the side guide rollers 662 can assist in clamping and positioning the wood. During the clamping process, the side guide rollers 662 and the inner guide rollers 664 can clamp the wood. At the same time, the side guide rollers 662 and the inner guide rollers 664 can also assist in guiding it, so that the wood can move stably on the inner side of the receiving plate 63 and the side frames 661, so that the wood can be quickly and stably cut by the splitting blade 7 in the cutting groove 5. In addition, during the cutting process, the device can assist in clamping the wood by linking the adjusting component 64, the starting component and the guide component 66, and can adapt to wood of different sizes for splitting processing, which significantly improves the overall production and processing efficiency of the device.
