Description

Technical Field

[0001] This utility model belongs to the field of stone cutting technology, specifically a road paving stone cutting device. Background Technology

[0002] Outdoor roads, squares, and parking lots are usually beautified by paving stones. Depending on the paving scenario, the layout, structure, and size of the paving stones will vary. In the existing technology, a cutting machine is usually configured when paving road stones in order to cut the stones into shapes suitable for paving.

[0003] A search revealed that patent CN116198035A discloses an adjustable cutting and shaping device for road paving stones, comprising: a base plate; two side frames fixedly mounted on the left and right sides of the base plate; a crossbeam fixedly mounted between the two side frames; a rectangular frame movably fitted onto the crossbeam; a cylinder fixedly mounted on the bottom of the rectangular frame, with a wheel sleeve fixedly connected to the bottom end of its output shaft. A cutting wheel is rotatably mounted inside the wheel sleeve, and a drive shaft is fixedly mounted at the center of the cutting wheel. The drive shaft is fixedly mounted on the end of the output shaft of a cutting motor, and the cutting motor is fixedly mounted on the wheel sleeve. When the stone to be cut is placed on the placement plate, the extension of the cylinder's output shaft causes the wheel sleeve and cutting wheel to move downwards to contact the stone. The rotation of the lead screw causes the lead nut to move left and right, thereby moving the rectangular frame, cylinder, wheel sleeve, and cutting wheel left and right to perform straight-line cutting of the stone into the desired shape.

[0004] Analysis of the above technical solutions reveals that, because the dust suppression mechanism is fixedly mounted on the side frame, it does not move with the cutting equipment, resulting in a low dust suppression effect. Furthermore, wastewater generated during the dust suppression process easily accumulates on the placement slab. Therefore, we provide a road paving stone cutting device to solve these problems.

[0014] 1. This utility model, through the combined setup of a dust suppression mechanism and a water blocking mechanism, enables the dust suppression mechanism to move along with the cutting equipment. When the cutting equipment is cutting, the pump body draws water from the water storage tank and delivers it to the hose. Finally, the water is sprayed onto the cutting blade of the cutting equipment through the spraying component, thereby achieving the effect of dust suppression and cooling the cutting blade. At the same time, the side of the stone pushes up the water blocking frame, causing the water blocking frame to swing until it slides on the upper surface of the stone, thus blocking the water splashed by the rotating cutting equipment and preventing water from splashing everywhere.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, such as Figure 1-9 As shown, this embodiment proposes a road paving stone cutting device, including a cutting table 2, with a cutting device 5 mounted above the cutting table 2. The cutting device 5 is a mature existing technology and moves via an electric slide rail. The cutting device 5 is equipped with a dust suppression mechanism and a water blocking mechanism. The cutting blade on the cutting device 5 rotates clockwise, positioning the water blocking mechanism on the left side of the cutting device 5 and the dust suppression mechanism on the right side. When the dust suppression mechanism is working, the water blocking mechanism can block the water splashing from the rotating mechanism. A water collection frame 1 is fixedly connected to the outside of the cutting table 2 to collect wastewater from the dust suppression mechanism, preventing it from flowing outside the cutting table 2. An extension plate 3 is slidably mounted on the inner wall of the water collection frame 1. Cylinders 4 are installed at the four corners of the water collection frame 1, and the telescopic ends of the cylinders 4 are fixedly connected to the top of the extension plate 3. The extension plate 3 and the cylinders 4 work together to control the flow of water. With cylinder 4 installed, the wastewater enclosure can be raised, thus preventing wastewater from splashing onto the outside of the collection frame 1. Furthermore, the extension plate 3 can be lowered into the collection frame 1 by the operation of cylinder 4, thus not hindering the normal handling of the stone and improving the practicality of the device. Two opposing drainage channels 13 are provided on the inner bottom wall of the collection frame 1, allowing wastewater entering the collection frame 1 to be discharged through these channels. Drainage pipes 10 are fixedly connected to both sides of the collection frame 1, and these pipes 10 are connected to the drainage channels 13. Each drainage pipe 10 is equipped with an L-shaped filter screen 11, which filters debris from the wastewater. The drainage pipes 10 are connected to the external sewer system. The machinery, parts, and equipment in this device all use conventional models from the prior art, and the electrical connections also use conventional connection methods from the prior art, which will not be detailed here.

[0028] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:

[0029] like Figure 1 and Figure 4As shown, the dust suppression mechanism includes a water tank 6, which is fixed to the back of the cutting equipment 5. A pump body 7 is installed at the bottom of the water tank 6. The water inlet of the pump body 7 is connected to the water tank 6, and the drain of the pump body 7 is connected to a hose 8. A spraying component is installed at the bottom of the hose 8. With the above structure, the dust suppression mechanism can move with the cutting equipment 5. In actual use, water is first poured into the water tank 6. When the cutting equipment 5 is cutting, the pump body 7 is used to draw water from the water tank 6 and deliver it to the hose 8. Finally, the spraying component sprays the water onto the cutting blade of the cutting equipment 5, thereby achieving the effect of dust suppression and cooling the cutting blade.

[0030] like Figure 7 As shown, the spraying assembly includes a water outlet pipe 19 and a fixing block 20. The fixing block 20 is fixed to the right side of the cutting device 5, and the bottom end of the hose 8 is fixed to the middle of the fixing block 20. The water outlet pipe 19 is connected to the bottom end of the hose 8, and several nozzles 21 are connected to the surface of the water outlet pipe 19. When water is delivered to the water outlet pipe 19 through the hose 8, it is finally sprayed onto the cutting blade of the cutting device 5 in operation through the nozzles 21 to reduce dust generated during the cutting process, thereby reducing dust in the working environment.

[0031] like Figure 1 As shown, the water-blocking mechanism includes a U-shaped plate 18 and a water-blocking frame 9. The U-shaped plate 18 is fixedly connected to the surface of the cutting equipment 5. A swing plate 15 is rotatably connected to the inner wall of the U-shaped plate 18. The water-blocking frame 9 is fixedly connected to the bottom end of the swing plate 15. With the above structure, when the cutting equipment 5 starts cutting the stone, the side of the stone will push the water-blocking frame 9 up, causing the water-blocking frame 9 to swing until the water-blocking frame 9 slides on the upper surface of the stone. When the dust-reducing mechanism sprays water on the cutting equipment 5, the water-blocking frame 9 will block the water splashed by the rotating cutting equipment 5. The front and back of the water-blocking frame 9 can also prevent water from splashing out from both sides, thereby improving the water blocking range.

[0032] like Figure 5 and Figure 9 As shown, a guide rod 16 is fixedly connected to the surface of the cutting device 5, and a swing plate 15 is sleeved on the surface of the guide rod 16. A spring 17 is sleeved on the surface of the guide rod 16. The two ends of the spring 17 are fixedly connected to the surface of the swing plate 15 and the surface of the cutting device 5, respectively. With the above structure, when the bottom end of the water-blocking frame 9 does not contact the stone, the water-blocking frame 9 will automatically reset under the elastic force of the spring 17.

[0033] like Figure 2 and Figure 3As shown, the inner wall of the water collection frame 1 is provided with two opposing first guide seats 12 and two opposing second guide seats 14, and the two ends of the two second guide seats 14 are lower than the two ends of the first guide seats 12. With the arrangement of the first guide seats 12 and the second guide seats 14, the wastewater on the cutting table 2 will flow to all sides. When the wastewater flows to the first guide seat 12, it will flow to the second guide seats 14 on both sides, and the wastewater will be discharged through the drain trough 13 by the guide and collection of the second guide seats 14, so as to avoid the accumulation of wastewater inside the water collection frame 1. The middle part of the first guide seat 12 is inclined to both sides, so that the shape of the first guide seat 12 is convex. The second guide seat 14 is inclined to the middle, so that the middle part of the second guide seat 14 is concave.

[0034] like Figure 8 As shown, a limiting block is fixed to the inner wall of the drain pipe 10, and the bottom surface of the L-shaped filter screen 11 is supported on the limiting block. Two opposing limiting shafts are fixed to the drain pipe 10, and the top of the L-shaped filter screen 11 is sleeved on the two limiting shafts. This allows the L-shaped filter screen 11 to be quickly fixed inside the drain pipe 10, ensuring the stability of the L-shaped filter screen 11 and preventing it from tilting. It also ensures the filtration effect on wastewater. Furthermore, the L-shaped filter screen 11 is easier to remove; simply pull it upwards.

[0035] The working principle and usage process of this utility model are as follows: First, water is poured into the water storage tank 6. Then, the stone is placed on the cutting table 2. Subsequently, the cutting equipment 5 is used for cutting. At the same time, the pump body 7 is turned on to draw water from the water storage tank 6 and deliver it to the hose 8. Finally, the water is sprayed onto the cutting blade of the cutting equipment 5 through the spraying component, thereby achieving a dust reduction effect. It can move with the cutting equipment 5 and also has a cooling effect on the cutting blade. In addition, the side of the stone will push up the water-blocking frame 9, causing the water-blocking frame 9 to swing until it blocks the water. The frame 9 slides on the upper surface of the stone, blocking the water splashed by the rotating cutting equipment 5, preventing wastewater from splashing everywhere. The blocked wastewater flows on the cutting table 2 into the water collection frame 1 and is discharged through the drainage channel 13 and the drain pipe 10. The extension plate 3 can be used to raise the barrier against wastewater, thereby preventing wastewater from splashing to the outside of the water collection frame 1 and ensuring a clean working environment. The extension plate 3 can be lowered into the water collection frame 1 by the operation of the cylinder 4, so it will not hinder the normal handling of the stone and improve the practicality of the device.
