Abstract
Description
Technical Field
[0001] This invention relates to the field of stone processing, specifically to a stone conveying and reversing device. Background Technology
[0002] With the rapid development of modern industrial technology, more and more residences, villas, parks, and other decorations require the use of various types of stone. In stone processing, especially in the processing of slate cultured stone, it is generally required that at least one surface of the stone retain a natural face. Therefore, multi-blade saws are usually used to cut the stone slabs into several parallel square stone strips. Then, a natural face splitter is used to compress each square stone strip, causing it to fracture brittlely, thus obtaining a stone block with a natural cross-section. In existing natural face stone processing, the square stone strips need to be manually moved and arranged into the splitter production line for stone production; or multiple conveyor belts need to be combined for reversal and arrangement so that the single square stone strips can enter the splitter production line for processing in sequence; thus, the processing efficiency of stone is greatly reduced.

[0005] Furthermore, the transverse conveying device also includes a transverse drive chain and a transverse drive motor, the transverse drive motor being fixedly mounted on the transverse frame; a transverse driven gear is mounted on one end of the conveying roller, and a transverse driving gear is connected to the output shaft of the transverse drive motor, the transverse driving gear being connected to the transverse drive chain and the transverse driven gear.
[0006] Furthermore, four lifting cylinders are provided below the transverse conveying device, respectively located at the four corners of the transverse frame. The upper end of each lifting cylinder is fixedly connected to the transverse frame, and the lower end of each lifting cylinder is fixedly connected to the base frame.
[0007] Furthermore, a square stabilizing bracket is installed between the transverse frame and the base frame. The stabilizing bracket includes a hinge seat and a connecting rod. The hinge seat is located at the four corners of the stabilizing bracket, and the connecting rod is connected to the hinge seat.
[0008] Furthermore, a limiting strip is formed on one side of the transverse frame.
[0009] Furthermore, the hinge base includes an upper hinge support, an upper hinge arm, a lower hinge support, and a lower hinge arm; the upper hinge support is fixedly connected to the transverse frame, the upper end of the upper hinge arm is hinged to the upper hinge support, the lower hinge support is fixedly connected to the base frame, and the lower end of the lower hinge arm is hinged to the lower hinge support; the lower end of the upper hinge arm and the upper end of the lower hinge arm are hinged together.
[0010] Furthermore, the longitudinal conveying device also includes a longitudinal drive chain, a longitudinal drive motor, and a synchronous shaft; the drive wheels of several conveyor belts are fixedly mounted on the synchronous shaft; a longitudinal drive gear is connected to the output shaft of the longitudinal drive motor, and a longitudinal driven gear is mounted on the synchronous shaft; the longitudinal drive gear drives the longitudinal driven gear through the longitudinal drive chain.
[0011] Furthermore, the adjustment device includes an adjustment gear, an adjustment shaft, an adjustment rack, and a handwheel; the adjustment gear is fixedly mounted on the adjustment shaft, the adjustment shaft is rotatably fixedly mounted on the base frame, the handwheel is fixedly mounted on the end of the adjustment shaft, the adjustment gear is fixedly mounted on the longitudinal frame, and the adjustment gear and the adjustment rack are meshed together.
[0012] Furthermore, a fixing hole is formed on the longitudinal frame, and a strip hole is formed on the base frame. The fixing hole and the strip hole are aligned, and the fixing hole and the strip hole are fixed by bolts.
[0013] Furthermore, the V-shaped guide rail includes a base, a V-shaped groove, guide wheels, and a guide rail cylinder; the V-shaped groove is formed on the base; there are several guide wheels, which are arranged on both sides of the V-shaped groove; one end of the base is hinged to the base frame, the upper end of the guide rail cylinder is hinged to the lower part of the base, and the lower end of the guide rail cylinder is hinged to the base frame.
[0014] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved: In operation, the distance between the longitudinal conveying device and the V-shaped guide rail is first adjusted using the adjustment device to better match the specifications of the square stone strips, facilitating their feeding into the V-shaped guide rails. The transverse conveying device is initially in its initial position, with the conveying rollers higher than the conveyor belt. As the conveying rollers rotate, several parallel square stone strips are conveyed above the longitudinal conveying device, i.e., above the conveyor belt. The transverse conveying device is then lowered until the square stone strips detach from the conveying rollers. At this point, the square stone strips are placed on the conveyor belt, and the conveyor belt is started, conveying the square stone strips longitudinally until they fall sequentially into the V-shaped guide rails. The square stone strips are then fed out through the V-shaped guide rails. Therefore, the reversing device can feed several parallel square stone strips out sequentially, one by one, greatly improving the stone conveying efficiency and thus increasing the production efficiency of natural stone.
[0015] Second, as the transverse drive motor rotates, it drives the transverse drive gear to rotate, which in turn drives the transverse driven gear to rotate via the transverse drive chain, thereby driving the conveying roller to rotate.

Detailed Implementation
[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see the appendix Figures 1 to 7As shown, the present invention provides a stone conveying reversing device, including a base frame 1, a transverse conveying device 2, a longitudinal conveying device 3, and an adjusting device 4; the transverse conveying device 2 includes a transverse frame 21 and a plurality of conveying rollers 22, the plurality of conveying rollers 22 being rotatably mounted on the transverse frame 21, and the transverse frame 21 being liftably mounted on the base frame 1; the longitudinal conveying device 3 includes a longitudinal frame 31 and a plurality of conveyor belts 32, the longitudinal frame 31 being longitudinally movable and connected to the base frame 1 through the adjusting device 4, and the plurality of conveyor belts 32 being arranged parallel to the longitudinal frame 31; the conveyor belts 32 and the conveying rollers 22 are arranged alternately in parallel, and a V-shaped guide rail 5 is provided on the base frame 1 on one side of the output end of the longitudinal conveying device 3. In use, the distance between the longitudinal conveying device 3 and the V-shaped guide rail 5 is first adjusted longitudinally using the adjustment device 4 to better match the specifications of the square stone strips 1000, facilitating the feeding of the square stone strips 1000 into the V-shaped guide rail 5. The transverse conveying device 2 is initially in the initial position, at which point the conveying roller 22 is higher than the conveyor belt 32. Therefore, as the conveying roller 22 rotates, several parallel square stone strips 1000 are conveyed above the longitudinal conveying device 3, that is, the square stone strips 1000 are conveyed above the conveyor belt 32. Then, the transverse conveying device 2 is lowered until the square stone strips 1000 are separated from the conveying roller 22. At this point, the square stone strips 1000 are placed on the conveyor belt 32. The conveyor belt 32 is then started to convey the square stone strips 1000 longitudinally until they fall into the V-shaped guide rail 5 in sequence. Finally, the square stone strips 1000 are sent out through the V-shaped guide rail 5. Therefore, the reversing device can send out several parallel square stone strips 1000 one by one in sequence, which greatly improves the stone conveying efficiency and thus improves the production efficiency of natural stone.
[0022] Preferably, such as Figure 4 As shown, the transverse conveying device 2 also includes a transverse drive chain 23 and a transverse drive motor 24. The transverse drive motor 24 is fixedly mounted on the transverse frame 21. A transverse driven gear 25 is installed at one end of the conveying roller 22. The output shaft of the transverse drive motor 24 is connected to a transverse drive gear 26, which is connected to the transverse drive chain 23 and the transverse driven gear 25. As the transverse drive motor 24 rotates, it drives the transverse drive gear 26 to rotate, which in turn drives the transverse drive chain 23 to drive the transverse driven gear 25 to rotate, thereby driving the conveying roller 22 to rotate. Therefore, several conveying rollers 22 can rotate synchronously, improving the stability of the square stone strips 1000 during conveying.
[0023] Preferably, such as Figure 3As shown, four lifting cylinders 27 are installed below the transverse conveying device 2, respectively located at the four corners of the transverse frame 21. The upper end of each lifting cylinder 27 is fixedly connected to the transverse frame 21, and the lower end of each lifting cylinder 27 is fixedly connected to the base frame 1. The lifting cylinders 27 are positioned at the four corners of the bottom of the square transverse frame 21, which improves the stability of the transverse conveying device 2 during lifting.
[0024] Preferably, a square stabilizing bracket 6 is also installed between the transverse frame 21 and the base frame 1. The stabilizing bracket 6 includes a hinge seat 61 and a connecting rod 62. The hinge seat 61 is located at the four corners of the stabilizing bracket 6, and the connecting rod 62 is connected to the hinge seat 61. The hinge seat 61 includes an upper hinge support 611, an upper hinge arm 612, a lower hinge support 613, and a lower hinge arm 614. The upper hinge support 611 is fixedly connected to the transverse frame 21. The upper end of the upper hinge arm 612 is hinged to the upper hinge support 611. The lower hinge support 613 is fixedly connected to the base frame 1. The lower end of the lower hinge arm 614 is hinged to the lower hinge support 613. The lower end of the upper hinge arm 612 and the upper end of the lower hinge arm 614 are hinged together. In this way, the stabilizing bracket 6 can be stretched or compressed as the transverse frame 21 moves up and down, which makes the force on the transverse frame 21 more balanced, thereby improving the overall rigidity and stability of the transverse frame 21.
[0025] Preferably, a limiting strip 28 is formed on one side of the transverse frame 21. This can limit the square stone strip 1000 in the transverse direction, preventing it from falling due to excessive transverse conveying distance, and can also align the square stone strip 1000 for easy conveying by the conveyor belt 32.
[0026] Preferably, such as Figure 5 As shown, the longitudinal conveying device 3 further includes a longitudinal drive chain 33, a longitudinal drive motor 34, and a synchronous shaft 35; the drive wheels of several conveyor belts 32 are fixedly mounted on the synchronous shaft 35; a longitudinal drive gear 36 is connected to the output shaft of the longitudinal drive motor 34, and a longitudinal driven gear 37 is mounted on the synchronous shaft 35. The longitudinal drive gear 36 drives the longitudinal driven gear 37 through the longitudinal drive chain 33. In this way, the longitudinal drive motor 34 drives the conveyor belts 32 to convey the square stone strips 1000 towards the V-shaped guide rail 5.
[0027] Preferably, the adjustment device 4 includes an adjustment gear 41, an adjustment shaft 42, an adjustment rack 43, and a handwheel 44. The adjustment gear 41 is fixedly mounted on the adjustment shaft 42, which is rotatably fixedly mounted on the base frame 1. The handwheel 44 is fixedly mounted on the end of the adjustment shaft 42, and the adjustment gear 41 is fixedly mounted on the longitudinal frame 31. The adjustment gear 41 and the adjustment rack 43 are meshed together. By rotating the handwheel 44, the adjustment shaft 42 and the adjustment gear 41 will rotate, thereby driving the adjustment rack 43 to move. This allows the longitudinal frame 31 to adjust its distance from the V-shaped guide rail 5 longitudinally, thus facilitating the more stable placement of square stone strips 1000 of different specifications into the V-shaped guide rail 5, preventing breakage and improving the stability of the stone product. In addition, a fixing hole 38 is formed on the longitudinal frame 31, and a strip hole 12 is formed on the base frame 1. The fixing hole 38 and the strip hole 12 are aligned, and the fixing hole 38 and the strip hole 12 are fixed by bolts. In this way, after the longitudinal frame 31 is adjusted in position by the adjusting device 4, the longitudinal frame 31 and the base frame 1 can be fixed by bolts.
[0028] Preferably, such as Figure 2 and Figure 3 As shown, the V-shaped guide rail 5 includes a base 51, a V-shaped groove 52, guide wheels 53, and a guide rail cylinder 54. The V-shaped groove 52 is formed on the base 51. Several guide wheels 53 are arranged on both sides of the V-shaped groove 52. One end of the base 51 is hinged to the base frame 1, and the upper end of the guide rail cylinder 54 is hinged to the lower part of the base 51, while the lower end of the guide rail cylinder 54 is hinged to the base frame 1. When the guide rail cylinder 54 retracts, the V-shaped guide rail 5 tilts, allowing the square stone strip 1000 to slide along the V-shaped guide rail 5 under gravity. Furthermore, the guide wheels 53 reduce friction between the square stone strip 1000 and the sidewalls of the V-shaped groove 52.
[0029] Compared with the prior art, the present invention improves the stone conveying efficiency by using a stone conveying reversing device, which can adjust the conveying direction of the stone and send out several parallel square stone strips 1000 one by one in sequence, thereby improving the stone conveying efficiency and thus improving the stone processing efficiency.
