Description

Technical Field

[0001] The utility model relates to the technical field of road paving equipment, in particular to a permeable concrete road paving machine with a leveling mechanism. Background Art

[0002] With the development of technology, more and more road constructions are gradually adopting permeable concrete. During the paving process, the well-proportioned permeable concrete is usually poured into the prepared road mold first, and then the road surface is paved by a paving machine. Among the existing paving machines, there is a roller-type paving machine, but during the paving process, the roller of this type of paving machine is easy to stick to the permeable concrete, which will affect the effect of road paving.

[0003] The patent with publication number CN211815383U discloses a portable permeable concrete pavement paving device; it belongs to the field of road paving technology; its technical points include a paving roller and a bracket, the rear side of the paving roller is fixedly connected to a first motor, the top of the bracket is fixedly connected to a first slider, and a first spring is fixedly installed inside, a telescopic rod is hinged on the left side of the bracket, a scraper is fixedly connected to the bottom of the first spring, a directional frame is slidably connected to the surface of the first slider, a carriage is fixedly connected to the left side of the directional frame, a guide plate is hinged on the left side of the telescopic rod, a sleeve rod is rotatably connected to the middle part of the telescopic rod near the left side, and a second slider is slidably connected to the left side of the guide plate; the utility model drives the turntable to rotate by the second motor, drives the guide plate to move forward and backward, so that the telescopic rod swings back and forth around the sleeve rod, and finally moves the bracket forward and backward, so that the concrete stuck to the paving roller when paving the road can be removed in time.

[0004] When paving permeable concrete pavement, the above-mentioned prior art only has the paving roller to flatten the permeable concrete, and the permeable concrete is not poured evenly, and there will be some places with more permeable concrete and some places with less permeable concrete. When the paving roller passes by, although the permeable concrete pavement is paved, the bearing strength of the pavement at the positions with more and less permeable concrete will be different, affecting the paving quality of the permeable concrete pavement. In addition, the guide plate in the technical solution moves back and forth when cleaning the surface of the paving roller, and the paving roller rotates when working. This makes it impossible to clean the concrete adhered to the surface of some paving rollers in time, resulting in potholes in the permeable concrete pavement after paving. In view of this, we propose a permeable concrete pavement paving machine with a leveling mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a permeable concrete pavement paving machine with a leveling mechanism to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The paving assembly includes a second U-shaped frame, a paving roller is rotatably connected between the left and right sides of the inner wall of the second U-shaped frame, and a scraper is inclined downwardly between the left and right sides of the inner wall of the second U-shaped frame and near the top of the front side. The leveled permeable concrete is flattened by the paving roller, and the concrete adhered to the surface of the paving roller can be cleaned by the scraper, and the cleaned concrete will fall in the moving direction of the paving roller to avoid affecting the paved permeable concrete road surface;

The plurality of material-discharging plates are driven to rotate by the rotating shaft, and the rotation direction of the rotating shaft is opposite to that of the rotating shaft. The material-discharging plates can shift the gathered concrete toward the direction of movement of the paving roller to avoid concrete accumulation.

The right end of the rotating rod passes through the right side of the inner wall of the first U-shaped frame and is coaxially connected with a first single-groove driven pulley. The first single-groove driven pulley is connected to the double-groove driven pulley through a first transmission belt.

The two connecting plates can improve the stability of the first U-shaped frame and the second U-shaped frame.

[0014] Preferably, a second servo motor is provided on the top of the U-shaped plate through a mounting seat, and the end of the output shaft of the second servo motor is coaxially connected with a second single-groove driving pulley, the right end of the rotating shaft passes through the right side of the inner wall of the U-shaped plate and is coaxially connected with a second single-groove driven pulley, the second single-groove driving pulley is connected to the second single-groove driven pulley through a third transmission belt, the second servo motor drives the second single-groove driving pulley to rotate, and the second single-groove driving pulley drives the second single-groove driven pulley to rotate through the third transmission belt, thereby driving the rotating shaft to rotate.

Rollers are rotatably connected between the left and right sides of the inner wall of the frame-shaped bracket and close to the front and rear sides. The auxiliary components are located outside the erected road mold and do not affect the paving of the concrete pavement by the paving rollers, thereby facilitating the movement of the pavement paving machine.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The permeable concrete pavement paving machine with a leveling mechanism drives the forward spiral blade and the reverse spiral blade to rotate through the rotating rod. The forward spiral blade and the reverse spiral blade can gather the higher permeable concrete from both sides to the middle, and fill and level the concave parts while the permeable concrete moves, so that the poured permeable concrete can be paved more evenly, avoiding the problem of high density of some permeable concrete pavements and low density of some parts of permeable concrete pavements when the paving roller is paving.

[0018] 2. The scraper can clean the concrete adhering to the surface of the paving roller, and the cleaned concrete will fall in the moving direction of the paving roller to avoid affecting the paved permeable concrete pavement.

The outer wall of the rotating shaft 33 is provided with a plurality of material-dispensing plates 34 arranged in a circular array. Because the forward spiral blades 12 and the reverse spiral blades 13 will push the concrete toward the middle, the remaining concrete after the recess is filled will be gathered between the forward spiral blades 12 and the reverse spiral blades 13. The plurality of material-dispensing plates 34 are driven to rotate by the rotating shaft 33. The rotation direction of the rotating shaft 33 is opposite to that of the rotating shaft 33.

The first single-groove driving pulley 24 is driven to rotate by the first servo motor 23, and the first single-groove driving pulley 24 drives the double-groove driven pulley 25 to rotate through the second transmission belt 26.

[0035] Specifically, rubber wheels 14 are provided on the outer wall of the rotating rod 11 and near the left and right sides of the inner wall of the first U-shaped frame 10. The diameter of the rubber wheel 14 is the same as the diameter of the flattening roller 21. The two rubber wheels 14 play a role of auxiliary movement to prevent the forward spiral blades 12 and the reverse spiral blades 13 from excessively pushing the concrete to move, that is, to prevent excessive embedding into the concrete. The right end of the rotating rod 11 passes through the right side of the inner wall of the first U-shaped frame 10 and is coaxially connected with a first single-groove driven pulley 15. The first single-groove driven pulley 15 is transmission-connected to the double-groove driven pulley 25 through the first transmission belt 16. The double-groove driven pulley 25 drives the first single-groove driven pulley 15 to rotate through the first transmission belt 16, thereby driving the rotating rod 11 to rotate.

[0036] Furthermore, the top of the front side of the U-shaped plate 30 is fixedly connected to the middle of the rear side of the first U-shaped frame 10, and the top of the rear side of the U-shaped plate 30 is fixedly connected to the middle of the front side of the second U-shaped frame 20, so that the position of the U-shaped plate 30 is fixed, and at the same time, it plays a connecting role for the middle of the first U-shaped frame 10 and the second U-shaped frame 20.

The second servo motor 31 drives the second single-groove driving pulley 32 to rotate, and the second single-groove driving pulley 32 drives the second single-groove driven pulley 35 to rotate through the third transmission belt 36, thereby driving the rotating shaft 33 to rotate.

[0038] Furthermore, the two connecting plates 4 are provided with auxiliary components 5 on their opposite sides. The auxiliary components 5 include an F-shaped connecting plate 50 fixedly connected to the side of the connecting plate 4.

At the same time, the double-groove driven pulley 25 drives the first single-groove driven pulley 15 to rotate through the first transmission belt 16, thereby driving the rotating rod 11 to rotate, and then the rotating rod 11 drives the forward spiral blade 12 and the reverse spiral blade 13 to rotate. The forward spiral blade 12 and the reverse spiral blade 13 can gather the higher permeable concrete from both sides to the middle. , while the permeable concrete is moving, the depressions are filled and leveled, so that the poured permeable concrete can be paved more evenly, avoiding the problem that some permeable concrete pavements have high density and some permeable concrete pavements have low density when the paving roller 21 is paving. Under the action of the second servo motor 31, the second servo motor 31 drives the second single-groove driving pulley 32 to rotate, and the second single-groove driving pulley 32 drives the second single-groove driven pulley 35 to rotate through the third transmission belt 36, thereby driving the rotating shaft 33 to rotate, and the rotating shaft 33 drives multiple material stripping plates 34 to rotate.
