Description

Technical Field

[0001] This utility model relates to the field of stone splitting equipment technology, specifically to a stone splitting machine. Background Technology

[0002] Cobblestones, with their defined cross-sectional shape, are widely used in construction and carving. Their shape provides a pleasing visual experience. In cobblestone production, square stones are typically cut into smaller pieces under pressure. Chinese invention patent CN108858820B discloses a stone cutting device and stone products produced using it. The upper cutter is fixed to a saddle plate by a pin and can rotate around the pin at a predetermined angle, allowing for a larger contact area between the cutting edge and the stone. Furthermore, even with inconsistent stone sizes, the pressure applied by the upper cutter can be easily transmitted. Two cutting edges are formed in both the upper and lower cutters. The inventors discovered that stone materials have certain dimensional and shape errors after production and processing; the shape of the stone is not a regular square or rectangle. In practical use, the cutting device disclosed in the aforementioned patent cannot independently adjust the posture of the two cutting blades of the upper cutter. Furthermore, the stone itself has a certain weight, and maintaining its posture during cutting operations is crucial. If operators constantly hold or carry the stone, it is undoubtedly time-consuming, laborious, and poses operational hazards, making loading difficult. Therefore, there is an urgent need for a stone splitting machine that allows for adaptive adjustment of the posture of a single cutter during processing, ensures cutting effectiveness, and facilitates loading. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a stone splitting machine that enables adaptive adjustment of the posture of a single cutter during processing, ensures cutting effect, and facilitates material loading.

[0004] To solve the above-mentioned technical problems, this utility model includes a frame, which is equipped with a cutting mechanism. The cutting mechanism includes an upper cutting component and a lower cutting component located below the upper cutting component. The upper cutting component and the lower cutting component each include two cutting blades. The two cutting blades in the upper cutting component are distributed on the frame from left to right, and the two cutting blades in the lower cutting component are distributed on the frame from left to right. The two cutting blades in the upper cutting component and the two cutting blades in the lower cutting component are distributed on the frame from top to bottom. The upper cutting component can move closer to and further away from the lower cutting component. Its structural feature is that at least one pair of cutting blades is hinged to the frame by a hinge shaft. The frame is equipped with a material storage mechanism for accommodating stone and aligning the two sides of the stone with the two cutting blades in the lower cutting component.

[0005] With the above structure, by setting a hinge, the cutter can swing when in contact with the stone, and the cutter's posture can be adaptively adjusted to adapt to the shape of the stone's outer surface, ensuring stable contact with the stone. By setting at least one pair of swinging cutters, the cutting effect on the stone is guaranteed, ensuring the quality of the cobblestones. By setting a material storage mechanism, the entire piece of stone is placed on the storage mechanism during processing, with the two sides of the stone aligned with the two cutters in the lower cutting assembly. This eliminates the need for operators to manually hold the stone to maintain its overall posture, achieving convenient loading. When cutting the stone, the stone on the storage mechanism can be manually pushed closer to the four cutters. Finally, the two cutters in the upper cutting assembly move closer to the two cutters in the lower cutting assembly, so that the four cutters aligned with the four sides of the stone cut the stone into cobblestones.

[0006] Furthermore, the frame includes a fixed frame and a movable frame, the movable frame being slidably connected to the fixed frame. The fixed frame is provided with a driving component capable of driving the movable frame to slide up and down. The lower cutting component is located on the fixed frame, and the upper cutting component is located on the movable frame. By setting up the fixed frame, the movable frame, and the driving component, the driving component drives the movable frame to slide up and down, enabling the upper cutting component on the movable frame to move downwards towards the lower cutting component and upwards away from the lower cutting component.

[0007] Furthermore, the cutter includes a cutter holder and a cutter head detachably connected to the cutter holder, the cutter holder being hinged to the frame via a hinge shaft. By providing a cutter holder and cutter head, the cutter head can be replaced individually after damage, making maintenance convenient and cost-effective.

[0008] Furthermore, the frame is equipped with a buffer component, which is used to contact the side of the cutter with the hinged hinge pin closest to the frame. By setting up the buffer component, direct contact between the cutter and the frame is prevented after swinging, thus ensuring the overall service life of the cutter.

[0009] Furthermore, the material storage mechanism includes a mounting frame, which is elastically connected to the machine frame via elastic elements. The mounting frame is rotatably connected to several first and second rotating shafts for contacting the stone. The first and second rotating shafts are spaced apart along the front-back direction on the mounting frame. The first and second rotating shafts correspond to the two cutters in the cutting assembly in the front-back direction. After the first and second rotating shafts load the stone, the two lower sides of the stone are positioned above the two cutters in the cutting assembly. By setting the first and second rotating shafts, the first and second rotating shafts and the stone experience rolling friction, reducing the burden on pushing the stone and minimizing friction on the outer sides of the stone. The correspondence between the first and second rotating shafts and the two cutters in the cutting assembly ensures the consistency of the stone's posture during storage and cutting, thereby allowing the two sides of the stone to align with the two cutters in the cutting assembly. By incorporating elastic components, the mounting frame can move up and down. When cutting stone, the two lower sides of the stone can be spaced apart from the lower cutting component. When the upper cutting component contacts the stone, it applies downward pressure to the stone, causing the stone to move downward and contact the lower cutting component. This prevents interference between the two lower sides of the stone and the lower cutting component, ensuring the continuity of the stone cutting operation.

[0010] Furthermore, the mounting frame is equipped with a first support plate and a second support plate, which are distributed in a V-shape on the mounting frame. The first support plate is positioned between the cutting component and a first rotating shaft near the cutting component in the front-back direction, and the second support plate is positioned between the cutting component and a second rotating shaft near the cutting component in the front-back direction. By setting the first and second support plates, smaller stones after cutting can be supported, ensuring effective support for the stones.

[0011] In summary, this utility model has the advantages of being easy to use and having a reasonable structure. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

Figure 3 The lower side is the rear side of this utility model. Example 1

[0021] Reference Figures 1 to 4 The utility model includes a frame 1. The frame 1 is equipped with a cutting mechanism, which includes an upper cutting component and a lower cutting component located below the upper cutting component. The upper cutting component and the lower cutting component each include two cutting blades 2. The two cutting blades 2 in the upper cutting component are distributed on the frame 1 from left to right, and the two cutting blades 2 in the lower cutting component are distributed on the frame 1 from left to right. The two cutting blades 2 in the upper cutting component and the two cutting blades 2 in the lower cutting component are distributed on the frame 1 from top to bottom. The upper cutting component can move closer to and further away from the lower cutting component. The frame 1 includes a fixed frame 11 and a movable frame 12. The movable frame 12 is slidably connected to the fixed frame 11. The movable frame 12 can be slidably connected to the fixed frame 11 via a slide rail slider mechanism. The fixed frame 11 is equipped with a driving component 111 that can drive the movable frame 12 to slide up and down. The driving component 111 can be a hydraulic cylinder. The movable frame 12 is connected to the output end of the hydraulic cylinder. The lower cutting component is located on the fixed frame 11, and the upper cutting component is located on the movable frame 12. The driving component 111 drives the moving frame 12 to slide up and down, so that the upper cutting component on the moving frame 12 moves downward toward the lower cutting component and upward away from the lower cutting component.

[0022] Reference Figures 1 to 4At least one pair of the four cutting blades 2 is hinged to the frame 1 via a hinge pin 3. In this embodiment, two pairs of cutting blades 2, i.e., the four cutting blades 2, are respectively hinged to the frame 1 via hinge pins 3. Each cutting blade 2 includes a blade holder 21 and a cutting head 22 detachably connected to the blade holder 21. The blade holder 21 is hinged to the frame 1 via a hinge pin 3. The cutting head 22 can be detachably connected to the blade holder 21 via screws. If the cutting head 22 is damaged, it can be replaced individually, making maintenance convenient and cost-effective. The outer part of the cutting blade 2 is the cutting edge, which is the outer part of the cutting head 22. The line connecting the cutting edges of the two cutting blades 2 in the lower cutting assembly is approximately V-shaped, the line connecting the cutting edges of the two cutting blades 2 in the upper cutting assembly is approximately inverted V-shaped, and the line connecting the cutting edges of the four cutting blades 2 is a quadrilateral. The fixed frame 11 and the movable frame 12 are respectively provided with mounting slots to accommodate the lower cutting component and the upper cutting component. The hinge shaft 3 allows the cutter 2 to swing up and down around the hinge shaft 3 after being subjected to force. Preferably, the frame 1 is provided with a buffer 5, which is used to contact the side of the cutter 2 that is hinged to the hinge shaft 3 closest to the frame 1. That is, the buffer 5 is placed between the cutter 2 and the frame 1. The buffer 5 can be made of nylon. By setting the buffer 5, direct contact between the cutter 2 and the frame 1 is prevented after swinging, thus ensuring the overall service life of the cutter 2. (Refer to...) Figure 3 In the lower cutting assembly, the left and lower sides of the left-side cutter 2 are close to the fixed frame 11 in the frame 1. The gaps between the left side of the cutter 2 and the fixed frame 11, and between the lower side of the cutter 2 and the fixed frame 11, are used to avoid the swinging cutter 2. Buffers 5 are provided in both the gaps between the left side of the cutter 2 and the fixed frame 11, and between the lower side of the cutter 2 and the fixed frame 11. The number and size of the buffers 5 can be flexibly adjusted according to the actual operation. The placement of the buffers 5 on the side of the cutter 2 near the frame 1 that is hinged to the hinge pin 3 is not described in detail.

[0023] Reference Figures 1 to 4The frame 1 is equipped with a material storage mechanism 4 for accommodating stone and aligning the two sides of the stone with the two cutting blades 2 in the cutting assembly. The material storage mechanism 4 includes a mounting frame 41, which is elastically connected to the frame 1 via an elastic element 42, which can be a compression spring or a polyurethane block. The mounting frame 41 is rotatably connected to a plurality of first rotating shafts 43 and second rotating shafts 44 for contacting the stone. The plurality of first rotating shafts 43 are spaced apart on the mounting frame 41 in the front-back direction, and the plurality of second rotating shafts 44 are spaced apart on the mounting frame 41 in the front-back direction. The first rotating shafts 43 and second rotating shafts 44 are correspondingly arranged with the two cutting blades 2 in the cutting assembly in the front-back direction. The first rotating shafts 43 are front-back aligned with the left-side cutting blade 2 in the cutting assembly, and the second rotating shafts 44 are front-back aligned with the right-side cutting blade 2 in the cutting assembly. After the first rotating shafts 43 and second rotating shafts 44 carry the stone, the two lower sides of the stone are located above the two cutting blades 2 in the cutting assembly. The line connecting the axes of the first rotating shaft 43 and the second rotating shaft 44 forms a V-shape, with the tops of the first rotating shaft 43 and the second rotating shaft 44 positioned above the cutting edge of the cutter 2. The first rotating shaft 43 and the second rotating shaft 44 experience rolling friction with the stone, reducing the burden on pushing the stone and minimizing friction on its outer surface. The first rotating shaft 43 and the second rotating shaft 44 correspond to the two cutters 2 in the lower cutting assembly, ensuring the consistency of the stone's posture during storage and cutting, thus aligning the two sides of the stone with the two cutters 2 in the lower cutting assembly. By incorporating the elastic element 42, the mounting bracket 41 can move up and down. When cutting the stone, the two lower sides of the stone maintain a certain distance from the lower cutting assembly, meaning the two lower sides of the stone are positioned above the cutting edges of the two cutters 2 in the lower cutting assembly. When the upper cutting assembly contacts the stone, it applies downward pressure, causing the stone to move downwards and contact the lower cutting assembly, preventing interference between the two lower sides of the stone and the lower cutting assembly, and ensuring the continuity of the stone cutting operation.

[0024] Reference Figures 1 to 4 Preferably, the mounting frame 41 is provided with a first support plate 411 and a second support plate 412, which are distributed in a V-shape on the mounting frame 41. The first support plate 411 is positioned between the cutting component and the first rotating shaft 43 near the cutting component in the front-back direction, and the second support plate 412 is positioned between the cutting component and the second rotating shaft 44 near the cutting component in the front-back direction. The first support plate 411 and the second support plate 412 can support smaller stones after cutting, ensuring the support effect for the stones. Example 2

[0025] Reference Figure 5This embodiment provides another version, with the basic structure being the same as that in Embodiment 1. In this embodiment, the number of swingable cutters 2 is different. Two cutters 2 are fixed to the frame 1, and each cutter 2 is hinged to the frame 1 via a hinge pin 3. Specifically, one cutter 2 in the upper cutting assembly is hinged to the frame 1 via the hinge pin 3, and one cutter 2 in the lower cutting assembly, located away from the cutter 2 hinged to the hinge pin 3 in the upper cutting assembly, is also hinged to the frame 1 via the hinge pin 3. The swingable function of the two roughly centrally symmetrical cutters 2 ensures reliable contact and cutting of the stone. Example 3

[0026] Reference Figure 6 This embodiment provides another version, with the same basic structure as in Embodiment 1, except that the number of swingable cutters 2 is different. The two cutters 2 in the lower cutting assembly are fixed to the frame 1. The two cutters 2 in the upper cutting assembly are respectively hinged to the frame 1 via hinge pins 3. The swingable function of the two upper cutters 2 ensures reliable contact and cutting of the stone. Example 4

[0027] Reference Figure 7 This embodiment provides another version, with the same basic structure as in Embodiment 1, except that the number of swingable cutters 2 is different. The two cutters 2 in the upper cutting assembly are fixed to the frame 1. The two cutters 2 in the lower cutting assembly are respectively hinged to the frame 1 via hinge pins 3. The swingable function of the two lower cutters 2 ensures reliable contact and cutting of the stone.

[0028] In use, this invention features a hinge shaft 3 that allows the cutter 2 to swing upon contact with the stone, adaptively adjusting its posture to fit the shape of the stone's outer surface and ensuring stable contact. The presence of at least one pair of swinging cutters 2 ensures effective cutting and maintains the quality of the cobblestones. A storage mechanism 4 allows the entire stone to be placed on it during processing, with its two sides aligned with the two cutters 2 in the lower cutting assembly. This eliminates the need for manual handling to maintain the stone's overall shape, facilitating convenient loading. During cutting, the stone on the storage mechanism 4 can be manually pushed closer to the four cutters 2, ultimately bringing the two cutters 2 in the upper cutting assembly closer to the two cutters 2 in the lower cutting assembly. The four cutters 2, aligned with the stone's four sides, then cut the stone into cobblestones.

[0029] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of this patent, they should all fall within the protection scope of this utility model.
