Description

Technical Field

[0001] This invention relates to the field of concrete block production and cutting technology, specifically a concrete block cutting machine. Background Technology

[0002] As the world's population continues to increase, the demand for housing is also growing. With more and more houses being built, the amount of building materials used is also increasing, and concrete blocks are the most used of these building materials. In the process of manufacturing concrete blocks, large concrete blocks need to be cut into sizes that can be used for masonry, so concrete block cutting machines have appeared on the market.

[0003] Currently available concrete block cutting devices can cut a large concrete block into smaller concrete blocks of the same size. However, during the cutting process, large concrete blocks often experience positional shifts due to the inability to be positioned correctly. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a concrete block cutting machine, comprising a base plate, on the top of which support columns and fixing blocks are fixedly installed respectively. The fixing blocks are located at the four corners of the top of the base plate. A first motor is fixedly installed on the outer surface of the fixing blocks via a bracket. A transmission device is rotatably installed between the fixing blocks. A first crossbeam and a second crossbeam are fixedly installed on the top of the outer surface of the support columns respectively. A second motor is fixedly installed on the top of the first crossbeam via a bracket. A cylinder is fixedly installed on the top of the second crossbeam via a bracket. A water-filling device is fixedly installed between the crossbeams, with one end of the water-filling device penetrating the first crossbeam and extending to its other side. A first slide rail and a second slide rail are fixedly installed on the outer surface of the support column, respectively. The first slide rail is located below the first crossbeam, and the second slide rail is located below the second crossbeam. A cutting device is slidably installed between the first slide rails, and a limiting device is slidably installed between the second slide rails. Smooth rods are fixedly installed at both ends of the bottom of the first crossbeam. The end of the smooth rod away from the first crossbeam penetrates the cutting device and extends to its other side, where it is fixedly connected to the device's base plate. The smooth rod is slidably connected to the cutting device. When the first motor operates, by setting the limiting device, when the position of the large concrete block to be cut reaches the limiting device, the concrete block to be cut is exactly below the cutting device, thus achieving precise positioning of the concrete block to be cut.

[0005] Preferably, the cutting device includes a third crossbeam, a cutter, and a lead screw. The third crossbeam is slidably mounted on the outer surface of the guide rod. First sliders are fixedly mounted at both ends of the third crossbeam. The first sliders are slidably mounted in the first slide rail. A fourth crossbeam is fixedly mounted at the edges of both ends of the outer surface of the third crossbeam.

[0006] Preferably, the cutter is fixedly mounted on the outer surfaces of the third and fourth crossbeams. The top end of the lead screw passes through the bottom of the first crossbeam and extends to its other side, where it is fixedly connected to the output end of the second motor. The bottom end of the lead screw passes through the third crossbeam and extends to its other side, where it is rotatably connected to the base plate of the device. The third crossbeam is connected to the lead screw via its internal threads. The operation of the second motor causes the third crossbeam to move downwards, allowing the cutting device to cut the concrete block that has moved below it, thus achieving the purpose of cutting the concrete block.

[0007] Preferably, the cutter includes a tool mounting bracket, the top of which has a water spray hole that penetrates the tool mounting bracket and extends to its bottom. The outer surface of the tool mounting bracket has a first tool mounting groove and a second tool mounting groove, which penetrate the tool mounting bracket and extend into its interior.

[0008] Preferably, a longitudinal tool is detachably installed in the first tool mounting slot, and a transverse tool is detachably installed in the second tool mounting slot. The outer surface of the longitudinal tool has a tool mounting hole that penetrates the longitudinal tool and extends to its other side. The tool mounting hole is adapted to the size of the transverse tool. A first handle is fixedly installed at the end of the longitudinal tool, and a second handle is fixedly installed at the end of the transverse tool. By providing the first and second tool mounting slots, when tools become worn due to long-term use and need to be replaced, the longitudinal and transverse tools can be removed from the tool mounting bracket and replaced using the first and second handles, thus greatly saving workers' tool replacement time.

[0009] Preferably, the limiting device includes a displacement block, a fixing rod is fixedly installed on the top of the displacement block, one end of the fixing rod away from the displacement block passes through the second crossbeam and extends to the other side to be fixedly connected to the output end of the cylinder, and a second slider is fixedly installed on both sides of the outer surface of the displacement block, and the second slider is slidably installed in the second slide rail.

[0010] Preferably, a traction block is fixedly installed at the bottom of the second slider, and an angle limiting block is fixedly installed at the bottom edge of the traction block. A rotating groove is formed at the outer surface edge of the traction block, and a block longitudinal limiting block is rotatably installed on both sides of the inner wall of the rotating groove via a rotating shaft. A roller groove is formed at the bottom of the block longitudinal limiting block, and a wheel is rotatably installed on both sides of the inner wall of the roller groove via a rotating shaft. Before the block to be cut moves towards the limiting device through the transmission device, the cylinder operates to move the block longitudinal limiting block towards the upper surface of the transmission device. When the block longitudinal limiting block contacts the upper surface of the transmission device, the wheel will roll on the transmission device, thus preventing friction damage between the block longitudinal limiting block and the limiting device.

[0011] Preferably, the water supply device includes a water inlet pipe, which is fixedly installed between the first crossbeams. One end of the water inlet pipe passes through the first crossbeam and extends to the other side. A water outlet pipe is fixedly installed on the outer surface of the water inlet pipe, passing through the water inlet pipe and extending into its inner cavity. A nozzle is fixedly installed at the end of the water outlet pipe away from the water inlet pipe. When the cutting device starts cutting the concrete block, by connecting the water inlet pipe to a water source, the water source flows through the water outlet pipe to the nozzle, and then is evenly sprayed onto the outer surfaces of the longitudinal and transverse cutters through the nozzle. Therefore, the wear and tear on the cutters during the cutting of the concrete block can be reduced.

[0012] Preferably, the transmission device includes a first rotating rod, a second rotating rod, and a third rotating rod. The first rotating rod and the third rotating rod are rotatably mounted between the fixed blocks, and the third rotating rod is rotatably mounted between the support columns. One end of the first rotating rod passes through the fixed block and extends to its other side, where it is fixedly connected to the output end of the first motor.

[0013] Preferably, a first rotating roller is fixedly installed on the outer surface of the first rotating rod, a second rotating roller is fixedly installed on the outer surface of the second rotating rod, and a third rotating roller is fixedly installed on the outer surface of the third rotating rod. A conveyor belt is drivenly installed on the outer surfaces of the first, second, and third rotating rollers. A protective steel sleeve is fixedly installed on the outer surface of the conveyor belt, and lateral limiting blocks for the blocks are fixedly installed at the edges on both sides of the outer surface of the protective steel sleeve. When the worker places the concrete block to be cut using the first motor, the block is positioned between the lateral limiting blocks and then conveyed to the area directly below the cutting device by the conveyor belt. This effectively limits any lateral positional deviation between the concrete block to be cut and the cutting device.

[0014] This invention provides a concrete block cutting machine. It has the following beneficial effects:

[0015] (i) When the first motor of the concrete block cutting machine is working, by setting a limiting device, when the position of the large concrete block to be cut is close to the limiting device, the concrete block to be cut is just below the cutting device, thus achieving the purpose of precise positioning of the concrete block to be cut.

[0016] (ii) The concrete block cutting machine uses a second motor to move the third crossbeam downwards, which in turn causes the cutting device to cut the concrete block that has moved below the cutting device, thus achieving the purpose of cutting the concrete block.

[0017] (III) The concrete block cutting machine, by setting the first and second tool mounting slots, allows the longitudinal and transverse tools to be removed from the tool mounting frame and replaced when the tools are worn down due to long-term use. This greatly saves the time for workers to replace the tools.

[0018] (iv) Before the block to be cut moves to the limiting device through the transmission device, the cylinder works to make the longitudinal limiting block of the block move to the upper surface of the transmission device. When the longitudinal limiting block of the block touches the upper surface of the transmission device, the wheel will roll on the transmission device, thus preventing the longitudinal limiting block of the block from being damaged by friction with the limiting device.

[0019] (v) When the cutting device of the concrete block cutting machine starts cutting the concrete block, the water source is connected to the water inlet pipe and the water source will flow to the nozzle through the water outlet pipe and then be evenly sprayed onto the outer surface of the longitudinal and transverse blades through the nozzle. Therefore, the wear and consumption of the blades when cutting the concrete block can be reduced.

[0020] (vi) The concrete block cutting machine operates through the first motor. When the worker places the concrete block to be cut, the concrete block to be cut is placed between the block's transverse limiting blocks, and then conveyed to the cutting device directly below it by the conveyor belt. Therefore, it can achieve the purpose of limiting the positional deviation between the concrete block to be cut and the cutting device in the transverse direction. Attached Figure Description

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.

[0034] Please see Figure 1-5 The present invention provides a technical solution comprising a device base plate 1, wherein support columns 2 and fixing blocks 3 are fixedly installed on the top of the device base plate 1, the fixing blocks 3 are located at the four corners of the top of the device base plate 1, a first motor 12 is fixedly installed on the outer surface of the fixing blocks 3 by means of a bracket, a transmission device 5 is rotatably installed between the fixing blocks 3, a first crossbeam 4 and a second crossbeam 15 are fixedly installed on the top of the outer surface of the support columns 2, a second motor 14 is fixedly installed on the top of the first crossbeam 4 by means of a bracket, a cylinder 13 is fixedly installed on the top of the second crossbeam 15 by means of a bracket, and a water filling device 7 is fixedly installed between the first crossbeams 4, with one end of the water filling device 7 penetrating through... The first crossbeam 4 extends to its other side. The outer surface of the support column 2 is fixedly equipped with a first slide rail 10 and a second slide rail 11. The first slide rail 10 is located below the first crossbeam 4, and the second slide rail 11 is located below the second crossbeam 15. A cutting device 8 is slidably installed between the first slide rails 10, and a limiting device 9 is slidably installed between the second slide rails 11. Smooth rods 6 are fixedly installed at both ends of the bottom of the first crossbeam 4. One end of the smooth rod 6, away from the first crossbeam 4, passes through the cutting device 8 and extends to its other side, where it is fixedly connected to the device base plate 1. The smooth rod 6 is slidably connected to the cutting device 8, and is used to limit the positional deviation of the cutting device 8 during cutting. When the first motor 12 operates, by setting the limiting device 9, when the large concrete block to be cut touches the limiting device 9, the concrete block to be cut is directly below the cutting device 8, thus achieving precise positioning of the concrete block to be cut.

[0035] The cutting device 8 includes a third crossbeam 81, a cutter 84, and a lead screw 85. The cutter 84 is used to cut large concrete blocks. The third crossbeam 81 is slidably mounted on the outer surface of the smooth rod 6. First sliders 83 are fixedly mounted at both ends of the third crossbeam 81. The first sliders 83 are slidably mounted in the first slide rail 10. A fourth crossbeam 82 is fixedly mounted at the edges of both ends of the outer surface of the third crossbeam 81.

[0036] The cutter 84 is fixedly mounted on the outer surfaces of the third crossbeam 81 and the fourth crossbeam 82. The top end of the lead screw 85 passes through the bottom of the first crossbeam 4 and extends to its other side, where it is fixedly connected to the output end of the second motor 14. The bottom end of the lead screw 85 passes through the third crossbeam 81 and extends to its other side, where it is rotatably connected to the base plate 1 of the device. The third crossbeam 81 is connected to the lead screw 85 via its internal threads. When the second motor 14 operates, the third crossbeam 81 moves downward, causing the cutting device 8 to cut the concrete block that has moved below it, thus achieving the purpose of cutting the concrete block.

[0037] The cutter 84 includes a tool mounting bracket 841 for detachably mounting a cutting tool. The top of the tool mounting bracket 841 has a water spray hole 849 that penetrates through the tool mounting bracket 841 and extends to its bottom. The outer surface of the tool mounting bracket 841 has a first tool mounting groove 842 and a second tool mounting groove 843 that penetrate through the tool mounting bracket 841 and extend into its interior.

[0038] A longitudinal cutter 844 is detachably installed in the first cutter mounting slot 842, and a transverse cutter 845 is detachably installed in the second cutter mounting slot 843. A cutter mounting hole 848 is provided on the outer surface of the longitudinal cutter 844, and the cutter mounting hole 848 penetrates the longitudinal cutter 844 and extends to its other side. The cutter mounting hole 848 is adapted to the size of the transverse cutter 845. The cutter mounting hole 848 is used to install the transverse cutter 845. A first handle 846 is fixedly installed at the end of the longitudinal cutter 844. The first handle 846 is used to remove and install the longitudinal cutter 844. A second handle 847 is fixedly installed at the end of the transverse cutter 845. The second handle 847 is used to remove and install the transverse cutter 845. By setting the first tool mounting slot 842 and the second tool mounting slot 843, when the tool becomes worn due to long-term use and needs to be replaced, the longitudinal tool 844 and the transverse tool 845 can be taken out from the tool mounting bracket 841 and replaced by the first handle 846 and the second handle 847. Therefore, the time for staff to replace tools can be greatly saved.

[0039] Please see Figure 6-7 The present invention provides a technical solution: the limiting device 9 includes a displacement block 91, a fixing rod 92 is fixedly installed on the top of the displacement block 91, one end of the fixing rod 92 away from the displacement block 91 passes through the second crossbeam 15 and extends to the other side to be fixedly connected to the output end of the cylinder 13, and a second slider 93 is fixedly installed on both sides of the outer surface of the displacement block 91, and the second slider 93 is slidably installed in the second slide rail 11.

[0040] The bottom of the second slider 93 is fixedly equipped with a traction block 94, which is used to pull the longitudinal limiting block 97 of the block to move up and down. An angle limiting block 95 is fixedly installed at the bottom edge of the traction block 94. A rotating groove 96 is opened at the outer surface edge of the traction block 94. The longitudinal limiting block 97 of the block is rotatably installed on both sides of the inner wall of the rotating groove 96 through a rotating shaft. A roller groove 98 is opened at the bottom of the longitudinal limiting block 97 of the block. A wheel 99 is rotatably installed on both sides of the inner wall of the roller groove 98 through a rotating shaft. The wheel 99 can effectively prevent friction between the longitudinal limiting block 97 of the block and the transmission device 5. Before the block to be cut moves from the transmission device 5 to the limiting device 9, the cylinder 13 works to move the longitudinal limiting block 97 of the block towards the upper surface of the transmission device 5. When the longitudinal limiting block 97 of the block touches the upper surface of the transmission device 5, the wheel 99 will roll on the transmission device 5, thus preventing the longitudinal limiting block 97 of the block from rubbing against the limiting device 9 and causing damage.

[0041] Please see Figure 8-9 The present invention provides a technical solution: the water-adding device 7 includes a water inlet pipe 71, which is fixedly installed between the first crossbeams 4. One end of the water inlet pipe 71 passes through the first crossbeam 4 and extends to the other side. A water outlet pipe 72 is fixedly installed on the outer surface of the water inlet pipe 71. The water outlet pipe 72 passes through the water inlet pipe 71 and extends into its inner cavity. A nozzle 73 is fixedly installed at the end of the water outlet pipe 72 away from the water inlet pipe 71. The nozzle 73 can spray water evenly onto the surface of the cutting tools. When the cutting device 8 starts cutting the concrete blocks, by connecting the water inlet pipe 71 to the water source, the water source will flow through the water outlet pipe 72 to the nozzle 73, and then be evenly sprayed onto the outer surfaces of the longitudinal cutting tool 844 and the transverse cutting tool 845 through the nozzle 73. Therefore, the wear and tear of the cutting tools when cutting concrete blocks can be reduced.

[0042] Please see Figure 10-11 The present invention provides a technical solution: the transmission device 5 includes a first rotating rod 51, a second rotating rod 53 and a third rotating rod 55. The first rotating rod 51 and the third rotating rod 55 are respectively rotatably installed between the fixed blocks 3. The third rotating rod 55 is rotatably installed between the support columns 2. One end of the first rotating rod 51 passes through the fixed block 3 and extends to its other side to be fixedly connected to the output end of the first motor 12.

[0043] A first rotating roller 52 is fixedly mounted on the outer surface of the first rotating rod 51, a second rotating roller 54 is fixedly mounted on the outer surface of the second rotating rod 53, and a third rotating roller 56 is fixedly mounted on the outer surface of the third rotating rod 55. A conveyor belt 57 is drivenly mounted on the outer surfaces of the first rotating roller 52, the second rotating roller 54, and the third rotating roller 56. A protective steel sleeve 58 is fixedly mounted on the outer surface of the conveyor belt 57 to protect it. Lateral limiting blocks 59 are fixedly mounted on the edges of both sides of the outer surface of the protective steel sleeve 58 to prevent the blocks to be cut from shifting laterally during the conveying process. When the first motor 12 operates, the concrete blocks to be cut are placed between the lateral limiting blocks 59 by the worker, and then conveyed to the cutting device 8 directly below by the conveyor belt 57. This achieves the purpose of limiting the lateral positional deviation between the concrete blocks to be cut and the cutting device 8.

[0044] In operation, workers use transport machinery to move large concrete blocks to be cut to the upper surface of the conveyor belt 57 at the feeding position of the transmission device 5. They then turn on the power switch of cylinder 13, causing the limiting device 9 to move downwards. When the wheel 99 touches the conveyor belt 57 and the longitudinal limiting block 97 is parallel to the conveyor belt 57, the power switch of cylinder 13 is turned off, and the power switch of the first motor 12 is turned on, causing the large concrete block to move towards the limiting device 9. When the concrete block touches the limiting device 9, the power switch of the first motor 12 is turned off, and the power switch of cylinder 13 is turned on, causing the limiting device 9 to retract upwards to its original position. Then, the power switch of the second motor 14 is turned on, causing... The cutting device 8 moves downwards to cut the large concrete block. At the same time, the water supply device 7 is connected to the water source, and water is evenly sprayed onto the outer surfaces of the longitudinal blade 844 and the transverse blade 845 through the nozzle 73. After cutting is completed, the operator changes the rotation direction of the output end of the second motor 14 to return the cutting device 8 to its original position and disconnects the water supply device 7. Then, the power switch of the first motor 12 is turned on again to move the cut concrete block in the discharge direction. When the concrete block reaches the operable position, the power switch of the first motor 12 is turned off. At this time, the operator transports the cut concrete block to the storage location using transport machinery.

[0045] The replaceable tool section allows for the replacement of tools when they become worn out due to prolonged use. Workers can use the first handle 846 and the second handle 847 to remove the longitudinal tool 844 and the transverse tool 845 from the tool mounting bracket 841 and replace them, thus greatly saving workers' tool replacement time.

[0046] In the concrete block position control section, a limiting device 9 is set up so that when the concrete block is about to touch the longitudinal limiting block 97, it means that the concrete block is directly below the cutting device 8, prompting the operator to turn off the power switch of the first motor 12. By setting a transverse limiting block 59, the operator can prevent the lateral position of the concrete block to be cut from shifting when placing it on the transmission device 5. When the transmission device 5 is conveying the concrete block, the transverse limiting block 59 can limit the lateral shift of the concrete block.

[0047] The water supply device 7 is used to connect the water source to the water inlet pipe 71 when the cutting device 8 starts cutting the concrete block. The water source will flow to the nozzle 73 through the water outlet pipe 72 and then be evenly sprayed onto the outer surface of the longitudinal blade 844 and the transverse blade 845 through the nozzle 73. This can reduce the wear and tear of the blades when cutting the concrete block.
