[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention involves placing the wood to be split in a guide platform, and using a hydraulic cylinder to drive a pusher block to contact the wood, thus pushing the wood closer to the splitting blade. Through the continuous pushing of the hydraulic cylinder, the wood is squeezed against the splitting blade, splitting the wood. This reduces manual labor intensity, improves wood splitting efficiency, and enhances safety.
[0016] This utility model uses a limiting component, with a moving plate and a limiting block placed on both sides of the wood inside the guide platform, to restrict the range of motion of the wood and prevent the wood from shifting position when being pushed to split, thus affecting the splitting effect. By rotating the handle, the bidirectional screw is rotated, thereby adjusting the distance between the two connecting plates, which in turn drives the moving plate to adjust the distance, making it easy to control the spacing between the two moving plates. It is suitable for limiting the conveying of wood of different diameters and has high applicability.
[0017] This invention uses an adjustable component to adjust the longitudinal height of the wood-splitting knife, ensuring the uniformity of the size of the split wood when splitting wood of different diameters.
[0018] This invention features a guide plate and a collection box. The inverted V-shaped guide plate allows the split wood to slide down along both sides of the guide plate into the collection box for collection. The wood falling into the collection box then falls onto a filter plate, which filters out the debris. The debris then falls into a debris collection box for collection. This design facilitates the collection of both split wood and debris, reducing the hassle of cleaning and collecting. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example: Please refer to Figures 1-5 This embodiment provides a wood splitter, including a support frame 1. A guide platform 2 is fixedly connected to the top of the support frame 1. The guide platform 2 has a "U" shaped cross-section. Placing wood in the guide platform 2 prevents the wood from detaching from the side of the guide platform 2. A limiting component 3 is installed between the guide platform 2 and the support frame 1 to limit the range of motion of the wood. A fixed seat 4 is fixedly connected to the top of the support frame 1 on one side of the guide platform 2. A hydraulic cylinder 5 is installed on the side of the fixed seat 4 away from the guide platform 2. The output end of the hydraulic cylinder 5 passes through the fixed seat 4 and is fixedly connected to a push block 5. 01. A wood-splitting blade 6 is installed on the top of the support frame 1 on the other side of the guide platform 2. The wood-splitting blade 6 adopts a cross-shaped structure. An adjustment component 7 for adjusting the height of the wood-splitting blade 6 is installed on the support frame 1. A receiving box 9 is installed on one side of the support frame 1 near the wood-splitting blade 6. The wood to be split is placed in the guide platform 2. The hydraulic cylinder 5 drives the pusher block 501 to contact the wood, so as to push the wood close to the wood-splitting blade 6. Through the continuous pushing of the hydraulic cylinder 5, the wood is squeezed against the wood-splitting blade 6, splitting the wood, reducing the intensity of manual labor, improving the efficiency of wood splitting, and improving safety.
[0027] In this embodiment, as Figure 2As shown, the limiting component 3 includes two movable plates 301 disposed inside the guide platform 2 along its length. Several limiting blocks 302 are fixedly connected at equal intervals along the length of the two movable plates 301 on their adjacent sides. Multiple guide rods 303 are fixedly connected to the opposite sides of the two movable plates 301, with one end of each guide rod penetrating the guide platform 2. The limiting component 3 also includes a mounting frame 305 fixedly connected to the support frame 1. A bidirectional screw 306 is rotatably connected inside the mounting frame 305. One end of the bidirectional screw 306 extends out of the mounting frame 305 and is fixedly connected to a rotating handle 307. Connecting plates 304 are connected to the two ends of the bidirectional screw 306 with opposite rotation directions. Rotation of the bidirectional screw 306 is used to drive... Two connecting plates 304 are positioned close to or far from each other. One end of each connecting plate 304 is fixedly connected to one of the guide rods 303 on the moving plate 301. The moving plate 301 and the limiting block 302, which are located inside the guide table 2, are placed on both sides of the wood to limit its range of motion. It should be noted that the limiting block 302 is only close to the wood and does not contact it, to avoid the wood shifting position when pushing the wood to move and split, which would affect the splitting effect. By rotating the handle 307, the bidirectional screw 306 is rotated, thereby adjusting the distance between the two connecting plates 304, which in turn drives the moving plate 301 to adjust the distance. This facilitates the control of the gap between the two moving plates 301, making it suitable for limiting the conveying of wood of different diameters, with high applicability.
[0028] In this embodiment, as Figure 3 As shown, the adjustment component 7 includes a mounting bracket 701 fixedly connected to the support frame 1. The mounting bracket 701 has a U-shaped structure, and a mounting seat 702 is slidably connected inside the mounting bracket 701. An adjustment screw 703 is threadedly connected to the bottom of the mounting bracket 701, and the top end of the adjustment screw 703 is rotatably connected to the mounting seat 702. A through groove 101 is provided on the support frame 1 for the wood splitting knife 6 to pass through. The length of the through groove 101 is greater than the horizontal blade in the wood splitting knife 6. One end of the wood splitting knife 6 passes through the through groove 101 and is fixedly connected to the mounting seat 702 by bolts. When splitting wood of different diameters, in order to ensure the uniformity of the size of the split wood, the mounting seat 702 can be moved up and down within the mounting bracket 701 by rotating the adjustment screw 703, thereby driving the wood splitting knife 6 to move up and down synchronously to improve the uniformity of splitting the wood. By adjusting the wood splitting knife 6 downwards, the horizontal blade in the wood splitting knife 6 passes through the through groove 101, so that only the vertical blade of the wood splitting knife 6 is exposed to the outside, making it convenient to select the splitting method according to the needs.
[0029] In this embodiment, as Figure 1 As shown, a guide plate 8 is provided above the receiving box 9. The guide plate 8 has an inverted V-shaped structure. One end of the guide plate 8 is fixedly connected to the support frame 1. Through the inverted V-shaped guide plate 8, the split wood slides down along both sides of the guide plate 8 into the receiving box 9 for collection, thereby improving the collection efficiency.
[0030] In this embodiment, as Figure 4 As shown, a hollow positioning ring 901 is fixedly connected to the middle of the inside of the receiving box 9. A filter plate 902 is set on the top of the hollow positioning ring 901. A debris collection box 903 is movably installed at the bottom of the inside of the receiving box 9 and below the hollow positioning ring 901. An opening is opened on one side of the receiving box 9 for the debris collection box 903 to pass through. A handle 904 is fixedly connected to the side of the opening of the debris collection box 903. The hollow positioning ring 901 is used to fix the position of the filter plate 902. Wood falling into the receiving box 9 falls onto the filter plate 902, and the debris is filtered by the filter plate 902. The debris falls into the debris collection box 903 for collection, which facilitates the collection of wood after splitting and the collection of debris, reducing the trouble of cleaning and collection.
[0031] In this embodiment, as Figure 5 As shown, a pair of guide plates 905 are fixedly connected to the side of the receiving box 9 near the support frame 1. The end of the pair of guide plates 905 near the support frame 1 is designed to be flared outwards and bent. A first retaining sleeve 906 is fixedly connected to the outer wall of one of the guide plates 905. A second retaining sleeve 907 corresponding to the position of the first retaining sleeve 906 is fixedly connected to the support frame 1. A pin 908 is movably inserted into the first retaining sleeve 906 and the second retaining sleeve 907. By placing the pair of guide plates 905 on the outside of the support frame 1 and inserting the pin 908 into the first retaining sleeve 906 and the second retaining sleeve 907, the receiving box 9 and the support frame 1 are positioned and installed to prevent the receiving box 9 from being misaligned and affecting the collection effect.
[0032] Working principle: In use, first adjust the height of the limiting component 3 and the wood-splitting blade 6 according to the diameter of the wood to be split. By rotating the handle 307, the double-acting screw 306 is rotated, thereby adjusting the distance between the two connecting plates 304, which in turn drives the moving plate 301 to adjust the distance. Adjust the distance between the two moving plates 301 to a suitable distance. Then, by rotating the adjusting screw 703, the mounting base 702 is moved up and down within the mounting frame 701, thereby driving the wood-splitting blade 6 to move up and down synchronously. Adjust the wood-splitting blade 6 to a suitable height, place the wood to be split in the guide table 2, and position it between the two moving plates 301. The hydraulic cylinder 5 drives the pusher block 501 to contact the wood, pushing the wood closer to the wood-splitting blade. The blade 6, continuously pushed by the hydraulic cylinder 5, squeezes the wood against the splitting blade 6, splitting the wood. The moving plate 301 and the limiting block 302 are placed on both sides of the wood to limit its range of motion, preventing the wood from shifting position during splitting and affecting the splitting effect, thus ensuring the uniformity of the size of the split wood. The split wood slides down along both sides of the guide plate 8 into the collection box 9. The wood falling into the collection box 9 lands on the filter plate 902, where the filter plate 902 filters out the debris, which falls into the debris collection box 903 for collection. This facilitates the collection of both split wood and debris, reducing the hassle of cleaning and collection. This utility model reduces manual labor intensity, improves wood splitting efficiency, and enhances safety.
[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
