Description

Technical Field

[0001] This utility model relates to the field of permeable concrete technology, specifically a permeable concrete laying device. Background Technology

[0002] Permeable concrete pavement is permeable, which can quickly eliminate water accumulation on roads and squares during rain; it can also reduce the burden on urban drainage facilities during heavy rainfall and prevent river flooding and water pollution.

[0003] According to a public notice (Announcement No.: CN222822025U), a permeable cement concrete pavement laying device is used. In the above application, a spiral auger is set up to spread the pile of permeable cement concrete to both sides. Then, the spread permeable cement concrete is leveled by rotating the paving plate. After that, the leveled permeable cement concrete is scraped again by a scraper and the excess permeable cement concrete is scraped away. Finally, the initial compaction is carried out by a flattening roller, which greatly improves the laying efficiency of permeable cement concrete pavement.

[0004] However, in actual use, the auger can only transport cement in one direction, which makes it easy for cement to accumulate in one place and difficult to spread to other areas, resulting in potholes and uneven road surfaces. In view of this, we propose a permeable concrete paving device. Utility Model Content

[0005] The purpose of this invention is to provide a permeable concrete paving device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a permeable concrete paving device, comprising a shell, a roller rotatably connected to the lower outer wall of the shell, a handle fixedly connected to the upper outer wall of the shell, a leveling hydraulic rod fixedly connected to the outer wall of the shell, a sleeve fixedly connected to the output end of the leveling hydraulic rod, a pressing hydraulic rod fixedly connected to the inner wall of the sleeve, a scraper fixedly connected to the output end of the pressing hydraulic rod, and a diffusion component disposed inside the scraper, the diffusion component comprising: The motor is fixedly connected to the outer wall of the scraper. A reciprocating lead screw is fixedly connected to the output end of the motor. A slide block is slidably connected to the outer wall of the reciprocating lead screw. A toothed plate is fixedly connected to the outer wall of the slide block. A gear meshes on the outer wall of a gear plate. A nozzle is fixedly connected to the shaft of the gear. A hose is fixedly connected to the input end of the nozzle. A water tank is fixedly connected to the end of the hose away from the nozzle.

[0007] Preferably, the diffusion component has a reversing component inside. The reversing component includes a driving bevel gear, which is fixedly connected to the shaft of a gear. A transmission bevel gear meshes with the outer wall of the driving bevel gear. A rotating shaft is fixedly connected to the shaft of the transmission bevel gear. A reversing bevel gear meshes with the end of the transmission bevel gear away from the driving bevel gear. The reversing bevel gear is fixedly connected to the nozzle. When the gear rotates, the gear drives the driving bevel gear to rotate, causing the transmission bevel gear to rotate around the rotating shaft.

[0008] Preferably, the transmission bevel gear is rotatably connected to the inner wall of the scraper via a rotating shaft, and both the driving bevel gear and the reverse bevel gear are rotatably connected to the inner wall of the scraper, so that the positions of the driving bevel gear, the transmission bevel gear, and the reverse bevel gear do not change when the gears rotate, thereby ensuring that the driving bevel gear and the reverse bevel gear can always mesh with the transmission bevel gear.

[0009] Preferably, the lower outer wall of the scraper is provided with a slope, and the outer wall of the nozzle contacts the outer wall of the scraper. When the scraper scrapes concrete that exceeds a specified height, the excess concrete is blocked by the slope and is difficult to accumulate at a high place, preventing the concrete from piling up too high and overturning over the scraper and falling onto the road surface. The water sprayed from the nozzle can disperse the accumulated concrete, allowing the accumulated concrete to move better to areas with insufficient thickness.

[0010] Preferably, the upper outer wall of the water tank has a water inlet, and a small water pump is installed inside the water tank. The output end of the small water pump is connected to a hose, so that water can be added to the water tank from the water inlet. The water pump inside the water tank can pressurize the water, so that the water sprayed from the nozzle can better push the concrete to spread.

[0011] Preferably, the number of gears is set to several sets, and the several sets of gears are distributed in a linear array on the outer wall of the scraper, so that the gears drive several sets of nozzles to swing, which can fully disperse the accumulated concrete and prevent the concrete from accumulating too much and causing the concrete to overturn over the scraper.

[0012] Preferably, the gears are divided into two types. One type of gear is fixedly connected to the nozzle at its shaft center via a connecting rod, and the other type of gear is fixedly connected to the nozzle via a reversing assembly. The two types of gears are staggered on the inner wall of the scraper, so that when the nozzle rotates, it can push the accumulated concrete to different areas.

[0013] Compared with the prior art, the present invention provides a permeable concrete paving device, which has the following beneficial effects: 1. This permeable concrete paving device uses a motor to rotate a reciprocating screw, which in turn drives a slide to move back and forth. This causes the toothed plate to move back and forth and drives the meshing gear to rotate back and forth, causing the nozzle to swing. This allows the nozzle to spray water from the water tank evenly, effectively dispersing the accumulated concrete and allowing it to be better laid on the road surface, preventing unevenness.

[0014] 2. This permeable concrete paving device, through the rotation of the gear fixedly connected to the active bevel gear, can drive the active bevel gear to rotate, so that when the transmission bevel gear drives the reverse bevel gear to rotate, the direction of the nozzle swing is opposite to the direction of the gear rotation. In conjunction with the gear fixedly connected to the connecting rod, the nozzle can be rotated to push the accumulated concrete to different areas, making the concrete more dispersed.

Detailed Implementation

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a permeable concrete paving device, including a shell 1, a roller 2 rotatably connected to the lower outer wall of the shell 1, a handle 3 fixedly connected to the upper outer wall of the shell 1, a leveling hydraulic rod 4 fixedly connected to the outer wall of the shell 1, a sleeve 5 fixedly connected to the output end of the leveling hydraulic rod 4, a pressing hydraulic rod 6 fixedly connected to the inner wall of the sleeve 5, a scraper 7 fixedly connected to the output end of the pressing hydraulic rod 6, and a diffusion component 8 disposed inside the scraper 7, the diffusion component 8 including a motor 81, a reciprocating screw 82, a slide 83, and a toothed plate 84. Gear 85, nozzle 86, hose 87, water tank 88.

[0018] In one embodiment of this utility model, a motor 81 is fixedly connected to the outer wall of a scraper 7, a reciprocating lead screw 82 is fixedly connected to the output end of the motor 81, a slide block 83 is slidably connected to the outer wall of the reciprocating lead screw 82, and a toothed plate 84 is fixedly connected to the outer wall of the slide block 83.

[0019] In one embodiment of the present invention, a gear 85 meshes on the outer wall of a toothed plate 84, a nozzle 86 is fixedly connected to the shaft of the gear 85, a hose 87 is fixedly connected to the input end of the nozzle 86, and a water tank 88 is fixedly connected to the end of the hose 87 away from the nozzle 86.

[0020] In addition, the diffuser assembly 8 is internally provided with a reversing assembly 9, which includes a driving bevel gear 91. The driving bevel gear 91 is fixedly connected to the shaft of the gear 85. The outer wall of the driving bevel gear 91 is meshed with a transmission bevel gear 92. The shaft of the transmission bevel gear 92 is fixedly connected to a rotating shaft 93. The end of the transmission bevel gear 92 away from the driving bevel gear 91 is meshed with a reversing bevel gear 94. The reversing bevel gear 94 is fixedly connected to the nozzle 86. When the gear 85 rotates, the gear 85 drives the driving bevel gear 91 to rotate, causing the transmission bevel gear 92 to rotate around the rotating shaft 93. This causes the transmission bevel gear 92 to drive the reversing bevel gear 94 to rotate, making the direction of the nozzle 86 swing opposite to the direction of the gear 85's rotation.

[0021] In this embodiment of the present invention, the transmission bevel gear 92 is rotatably connected to the inner wall of the scraper 7 via the rotating shaft 93, and the driving bevel gear 91 and the reverse bevel gear 94 are both rotatably connected to the inner wall of the scraper 7. This ensures that when the gear 85 rotates, the positions of the driving bevel gear 91, the transmission bevel gear 92, and the reverse bevel gear 94 do not change, thereby ensuring that the driving bevel gear 91 and the reverse bevel gear 94 are always engaged with the transmission bevel gear 92, making the rotation of the nozzle 86 more stable.

[0022] In an embodiment of this utility model, the lower outer wall of the scraper 7 is provided with a slope, and the outer wall of the nozzle 86 contacts the outer wall of the scraper 7. When the scraper 7 scrapes concrete that exceeds a specified height, the excess concrete is blocked by the slope and is difficult to accumulate at a high place, preventing the concrete from piling up too high and overturning over the scraper 7 and falling onto the road surface. The water sprayed from the nozzle 86 can disperse the accumulated concrete, allowing the accumulated concrete to move better to areas with insufficient thickness, making the concrete road surface smoother.

[0023] In an embodiment of this utility model, a water inlet is provided on the upper outer wall of the water tank 88, and a small water pump is provided inside the water tank 88. The output end of the small water pump is connected to the hose 87, so that water can be added to the water tank 88 from the water inlet. The water pump inside the water tank 88 can pressurize the water, so that the water sprayed from the nozzle 86 can better push the concrete to disperse and prevent the concrete from accumulating.

[0024] In the embodiments of this utility model, the number of gears 85 is set to several groups, and the several groups of gears 85 are distributed in a linear array on the outer wall of the scraper 7, so that the gears 85 drive the several groups of nozzles 86 to swing, which can fully disperse the accumulated concrete, so that the concrete does not accumulate too much and cause the concrete to roll over the scraper 7, making the road surface uneven.

[0025] In the embodiments of this utility model, several sets of gears 85 are divided into two types. One type of gear 85 is fixedly connected to the nozzle 86 at its shaft center via a connecting rod, and the other type of gear 85 is fixedly connected to the nozzle 86 via a reversing component 9. The two types of gears 85 are alternately arranged on the inner wall of the scraper 7, so that when the nozzle 86 rotates, it can push the accumulated concrete to different areas, making the concrete more dispersed and better laid on the road surface.

[0026] In this invention, concrete is poured onto the road surface, and the leveling hydraulic rod 4 extends to adjust the height of the scraper 7 according to the required concrete laying height. At this time, the leveling hydraulic rod 4 retracts to allow the scraper 7 to level the concrete. Meanwhile, the motor 81 rotates the reciprocating screw 82, causing the slide 83 to move back and forth on the reciprocating screw 82. This causes the toothed plate 84 to move back and forth, driving the gear 85 to rotate back and forth, causing the nozzle 86 to swing. The nozzle 86 sprays water from the water tank 88, effectively dispersing the accumulated concrete and allowing it to be better laid on the road surface. When the gear 85, which is fixedly connected to the driving bevel gear 91, rotates, it drives the driving bevel gear 91 to rotate. When the transmission bevel gear 92 drives the reverse bevel gear 94 to rotate, the direction of the nozzle 86's swing is opposite to the direction of the gear 85's rotation. This, combined with the gear 85 fixedly connected to the connecting rod, allows the nozzle 86 to rotate, pushing the accumulated concrete to different areas and dispersing the concrete more evenly.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
