[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.
[0025] Please refer to Figure 1 , this utility model provides a PTO connection bracket combination structure for a log splitter, including a PTO connecting bracket 1 and an assembly component, and further including extension brackets. The extension brackets are connected to the PTO connecting bracket 1. The extension brackets include a left extension bracket 2 and a right extension bracket 3. The left extension bracket 2 and the right extension bracket 3 are respectively connected to the left and right sides of the PTO connecting bracket 1.
[0026] The structure of this utility model is simple and the connection is concise. By arranging the left extension bracket 2 and the right extension bracket 3 on the PTO connecting bracket 1, the log splitter is connected to the tractor through the extension brackets, so that a small-sized log splitter can be connected to the PTO connecting arm of a large-tonnage tractor, expanding the applicability of the log splitter and making it adaptable to PTO connecting arms of various sizes and models of tractors, which is convenient to use.
[0027] In this embodiment, as Figure 1 , Figure 2 shown, inner connection parts detachably connected to the PTO connecting bracket are provided at the inner ends of the left extension bracket 2 and the right extension bracket 3, and outer connection parts are provided at the outer ends of the left extension bracket and the right extension bracket.
[0028] Specifically, the PTO connecting bracket 1 includes a connecting bracket body 11. An upper hinge bracket 12, a left hinge bracket 13, and a right hinge bracket 14 are provided on the connecting bracket body 11. The left hinge bracket 13 and the right hinge bracket 14 are respectively connected to the left extension bracket 2 and the right extension bracket 3. The connecting bracket body 11 includes a bracket connecting plate. The PTO connecting bracket 1 is fixedly connected to the workbench of the log splitter through the bracket connecting plate. A PTO power input shaft 15 is connected to the connecting bracket body 1; the upper hinge bracket 12 is provided at one end of the connecting bracket body 1, and the left hinge bracket 13 and the right hinge bracket 14 are respectively provided on the left and right sides at the other end of the connecting bracket body 11.
[0029] In this embodiment, the upper hinge frame 12 is a channel steel plate structure, the left hinge frame 13 and the right hinge frame 14 are plate-shaped connection structures, and the left hinge frame 13 and the right hinge frame 14 are parallel and oppositely arranged. A plurality of bolt mounting holes and connecting pin mounting holes are provided on the upper hinge frame 12, the left hinge frame 13, and the right hinge frame 14 for installing bolts or connecting pins.
[0030] Furthermore, a limiting block 16 is also provided on the connecting frame body 11. The limiting block 16 is arranged at the lower ends of the left hinge frame 13 and the right hinge frame 14, and the limiting block 16 plays a limiting role.
[0031] As Figure 3 shown, the left extension bracket 2 and the right extension bracket 3 have the same structural settings. The extension brackets each include an intermediate connecting plate 21, an outer connecting plate 22, and a connecting pipe 23 connecting the intermediate connecting plate 21 and the outer connecting plate 22. The extension brackets are of an I-shaped structure welded integrally.
[0032] Specifically, in this embodiment, the extension brackets are connected to the PTO connecting frame 1 through the intermediate connecting plates 21. Among them, the left extension bracket 2 is connected to the left hinge frame 13 of the PTO connecting frame 1 through the intermediate connecting plate 21, and the right extension bracket 3 is connected to the right hinge frame 14 of the PTO connecting frame 1 through the intermediate connecting plate 21. The outer connecting plates 22 of the extension brackets are connected to the PTO connecting arms of the tractor to be connected.
[0033] Furthermore, the intermediate connecting plates 21 of the left extension bracket 2 and the right extension bracket 3 are respectively fixedly connected to the left hinge frame 13 and the right hinge frame 14 of the PTO connecting frame 1 through two connecting bolts. The outer connecting plates 22 of the left extension bracket 2 and the right extension bracket 3 are connected to the PTO connecting arms of the tractor through PTO connecting pins 4. Moreover, spring pins 5 are provided on the left hinge frame 13 and the right hinge frame 14. After the extension brackets and the PTO connecting frame 1 are fixed through the connecting bolts, positioning connection is carried out through the spring pins 5 to further ensure the stability of the connection.
[0034] Furthermore, as a preferred embodiment of the present utility model, the sizes of the two groups of connecting bolts used for connecting the brackets to each other can be the same or different. When using connecting bolts of the same size, the versatility can be improved and the connection is convenient. And the spring pins 5 can be set as needed. The spring pins can be replaced with bolt positioning according to actual use requirements, or the spring pins can be not provided, so as to reduce costs. Moreover, nut and other structures adapted to the connecting bolts, pins, and connecting pins can be provided to ensure the stability of use.
[0035] Furthermore, as Figure 1 shown, the present utility model further includes a support tail frame 6. The first end of the support tail frame 6 is connected to the upper hinge frame 12 of the PTO connecting frame 1, and the second end of the support tail frame 6 is provided with support rollers.
[0036] Specifically, the end of the support tailstock 6 is detachably connected to the upper hinge 12 of the PTO connecting frame 1 through the PTO connecting pin 4 and the tailstock pin 7. By adding the connection between the support tailstock 6 and the PTO connecting frame 1, support is provided for the mobile log splitter, reducing the labor intensity during movement.
[0037] Furthermore, in this embodiment, each structure adopts a detachable connection structure, improving the convenience of mobile transportation and being easy to install at the same time. When the log splitter needs to be moved, it is in a disconnected state from the tractor at this time. Insert the support tailstock 6 onto the upper hinge 12 of the PTO connecting frame 1, and fix it with the PTO connecting pin 4 and a tailstock pin 7. Insert another tailstock pin 7 to eliminate the clearance between the pin and the hole, improving the articulation rigidity and stability of the support tailstock 6, and keeping the movement stable when the log splitter moves.
[0038] In this embodiment, corresponding bolt mounting holes and connection pin mounting holes are provided on the left hinge 13, right hinge 14 of the PTO connecting frame 1, and the middle connecting plate 21 and outer connecting plate 22 of the extension bracket. And there are at least two bolt mounting holes. The specific number of connecting bolts can be adaptively adjusted according to actual needs, such as Figure 1 、 Figure 4 As shown, after loosening the connection bolts and spring pins 5 at the end away from the connecting pipe 23 of the two extension brackets, the extension brackets can swing backward around the remaining connection bolts at the end until blocked by the limit block 16. The limit block 16 on the PTO connecting frame 1 can limit the swing angle of the extension brackets.
[0039] Specifically, when the PTO connecting frame 1 of the log splitter is connected to the PTO connecting arm of a small tractor, keep the end connection bolts and remove other connection bolts. The left and right extension brackets swing backward and are limited by the limit block 16. The spring pin 5 pops out to limit the forward swing of the extension brackets. The PTO connecting frame 1 is connected to the connecting arm of the tractor through the upper hinge 12, left hinge 13, right hinge 14 and three groups of PTO connecting pins 4. The power of the tractor is transmitted to the PTO power input shaft 15 through the transmission shaft.
[0040] Furthermore, when the log splitter needs to be connected to the PTO connecting arm of a large-tonnage tractor, install the left and right extension brackets, pull out the spring pin 5 to make the extension brackets swing to the working position centered on the end bolts, insert the spring pin 5 for positioning, and fix it to the left and right hinges of the PTO connecting frame through other connection bolts. At this time, the tractor connecting arm is connected to the PTO connecting frame 1 through the upper hinge 12, the outer connecting plates 22 of the left and right extension frames and three groups of PTO connecting pins 4, realizing stable connection and power transmission.
[0041] The utility model provides a PTO connection bracket combination structure for a wood splitter. Through the mutual cooperation of a PTO connection bracket 1, a left extension bracket 2, a right extension bracket 3, a spring bolt 5, and a support tail frame 6, the PTO connection bracket of the wood splitter is connected to the PTO connection arms of various models of tractors and power transmission is achieved. According to the size of the connected tractor, an adapted connection method is selected. The structure is simple and the connection is straightforward. By arranging the left extension bracket 2 and the right extension bracket 3 on the PTO connection bracket 1, the wood splitter is connected to the tractor through the extension brackets, so that a small-sized wood splitter can be connected to the PTO connection arm of a large-tonnage tractor, solving the problem of non-matching connection between a small-sized wood splitter and a large-tonnage tractor, expanding the applicability of the wood splitter, and making it adapted to the PTO connection arms of various sizes and models of tractors, which is convenient to use. Moreover, the utility model provides support for the mobile wood splitter in the non-working state by adding the connection between the support tail frame and the PTO connection bracket, reducing the labor intensity of movement.
