Technical Field

[0001] The invention relates to the technical field of road paving equipment, in particular to a road paving device. Background Art

[0002] In the road construction industry, leveling equipment plays a core role. Its operating efficiency is directly related to the structural quality and construction rate of the road. The road leveling tools on the current market are reflected in two mainstreams: pavers and leveling electric rollers. Due to its strong working efficiency, pavers occupy a dominant position in large-scale road construction projects such as expressways and national highways, although its cost is relatively high and the operation and maintenance process is relatively cumbersome. Relatively speaking, leveling electric rollers are more popular in small-scale road construction or road maintenance tasks due to their simple operation, convenient maintenance, high working efficiency and excellent leveling effect.

[0003] However, there are some problems in the use of the existing leveling electric roller. First, the electric roller is prone to throw the cement attached to its surface onto the already leveled road surface during its forward movement, resulting in a decrease in the leveling effect and affecting the overall quality of the road. Secondly, a certain amount of loose cement is often accumulated in the forward direction of the electric roller. The existing technology is to spread the accumulated cement by manually standing in the forward direction of the electric roller, which not only affects the working efficiency of the electric roller, but also consumes more manpower.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, reference Figure 1 to Figure 9 , which is the first embodiment of the present invention, provides a road paving device, which includes a main body component 100, including a support seat 101, a support shaft 102, a pressure roller 103 and a drive motor 104. The support shaft 102 is rotatably connected in the support seat 101, the pressure roller 103 is fixed to the end of the support shaft 102, and the drive motor 104 is arranged on the support seat 101.

[0031] The support seat 101 is used to support the support shaft 102 and the driving motor 104, so that the driving motor 104 can stably drive the support shaft 102 to rotate, so that the support shaft 102 drives the pressure roller 103 to rotate, thereby leveling the road surface. The principle of the driving motor 104 driving the support shaft 102 to rotate is the existing technology, and technical personnel in this field should be clearly aware of it, and it will not be elaborated here.

[0032] The cleaning assembly 200 is arranged on the top of the support base 101, and includes a support block 201a fixed on the top of the support base 101, a rotating shaft 201b is rotatably connected inside the support block 201a, a side baffle 201c is fixed on one side of the rotating shaft 201b, a cover plate 201d is fixed between the two side baffles 201c, a scraper 201e is fixed on the inner wall of the cover plate 201d, a push plate 201f is fixed on one side of the scraper 201e, a first spring 201g is fixed on one side of the push plate 201f, and the other end of the first spring 201g is fixed to the surface of the cover plate 201d.

[0033] The support block 201a is used to support the rotating shaft 201b, so that the rotating shaft 201b can support the side baffle 201c, so that the two side baffles 201c on both sides of the cover plate 201d can stably support the cover plate 201d, and the scraper 201e is fixed to the bottom of the cover plate 201d by bolts, and the scraper 201e is located on the surface of the pressure roller 103, and the first spring 201g is in a compressed state. Through the reset elastic force of the first spring 201g, the first spring 201g can push the push plate 201f, so that the push plate 201f squeezes the scraper 201e toward the surface of the pressure roller 103, so that the scraper 201e can scrape the cement on the surface of the pressure roller 103, effectively preventing the cement from being thrown onto the leveled road surface, thereby significantly improving the flatness and overall quality of the road.

[0034] Specifically, the cleaning assembly 200 also includes a support member 202, which is arranged on the support base 101, including a rotating column 202a rotatably connected to the support base 101, a support sleeve 202b is fixed to one side of the rotating column 202a, and a threaded column 202c is rotatably connected to the support sleeve 202b.

[0035] The rotating column 202a is used to support the supporting sleeve 202b, and the supporting sleeve 202b is used to support the threaded column 202c, so that the threaded column 202c can rotate stably.

[0036] Specifically, the support member 202 also includes a support column 202d fixed to one side of the side baffle 201c, the surface of the support column 202d is rotatably connected to a rotating sleeve 202e, one side of the rotating sleeve 202e is fixed to a threaded sleeve 202f, and the threaded column 202c is rotatably connected to the threaded sleeve 202f through threads.

[0037] The support column 202d is used to support the rotating sleeve 202e, and the rotating sleeve 202e is used to support the threaded sleeve 202f, so that when the threaded column 202c rotates, it can drive the threaded sleeve 202f to move up and down, so that the threaded sleeve 202f drives the support column 202d to move up and down through the rotating sleeve 202e, thereby driving the side baffle 201c to deflect, so that the side baffle 201c drives the cover plate 201d to deflect, thereby adjusting the position between the scraper 201e and the pressure roller 103.

[0038] Example 2, reference Figure 1 to Figure 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the cleaning assembly 200 also includes a paving member 203, which is arranged below the cover plate 201d, including a support rod 203a rotatably connected to the side baffle 201c, a connecting sleeve 203b is fixed to the surface of the support rod 203a, and a paving plate 203c is fixed to one side of the connecting sleeve 203b.

[0040] The support rod 203a is used to support the connecting sleeve 203b, so that the connecting sleeve 203b can support the paving plate 203c. The paving plate 203c is used to spread the cement accumulated in front of the electric roller, so that there is no need for manual labor to stand in the forward direction of the electric roller to spread the accumulated cement, which reduces the need for manual intervention, speeds up the road paving, and significantly improves construction efficiency.

[0041] Specifically, the paving member 203 also includes a support frame 203d fixed to the inner top wall of the cover plate 201d, a second spring 203e is fixed to the bottom of the support frame 203d, and the other end of the second spring 203e is fixed to the top of the paving plate 203c.

[0042] The support frame 203d is used to fix and support the second spring 203e. The second spring 203e is in a compressed state and is used to push the paving board 203c so that the paving board 203c has a certain pressure applied to the accumulated cement in the forward direction of the electric roller, so that the cement can be better spread.

[0043] Specifically, the paving member 203 also includes a positioning gear 203f fixed to the surface of the support rod 203a, a positioning groove 203f-1 is defined in the positioning gear 203f, a positioning column 203g is fixed to one side of the side baffle 201c, and the positioning column 203g slides in the positioning groove 203f-1.

[0044] The positioning groove 203f-1 provided on the surface of the positioning gear 203f is used to position the angle of the support rod 203a. When the positioning column 203g is in the current position, the paving plate 203c cannot continue to deflect downward. When the electric roller moves in the direction of the accumulated cement, the accumulated cement will squeeze the paving plate 203c, causing the paving plate 203c to deflect upward. At this time, the paving plate 203c can drive the support rod 203a and the positioning gear 203f to rotate, so that the positioning column 203g moves toward the other end of the positioning groove 203f-1. At this time, the second spring 203e has a greater elastic force to squeeze the paving plate 203c. When the driving motor 104 drives the pressure roller 103 to rotate, the entire electric roller will vibrate at a higher frequency, causing the paving plate 203c to vibrate at a higher frequency at the same time. At this time, the paving plate 203c presses down the cement, and at the same time, with its own vibration, it can play the effect of a "vibrator", so that the accumulated cement is spread.

[0045] Specifically, the cleaning assembly 200 also includes an adjusting member 204, which is arranged on the threaded column 202c, including a cylinder 204a rotatably connected to the threaded column 202c, a third spring 204b is fixed to the top of the cylinder 204a, an adjusting rod 204c is fixed to the other end of the third spring 204b, and a plug-in sleeve 204d is fixed to the bottom of the adjusting rod 204c, and the plug-in sleeve 204d is plugged into the threaded column 202c.

[0046] The cylinder 204a is used to position the third spring 204b. The third spring 204b is in a stretched state. The pulling force of the third spring 204b can make the plug sleeve 204d plug into the threaded column 202c, thereby limiting the adjustment rod 204c.

[0047] Specifically, the adjusting member 204 also includes an adjusting disk 204e fixed to the top of the threaded column 202c, a positioning hole 204e-1 is opened on the surface of the adjusting disk 204e, and an insert rod 204f is fixed to the bottom of the adjusting rod 204c, and the insert rod 204f is inserted into the positioning hole 204e-1.

[0048] The adjusting disk 204e is used to drive the threaded column 202c to rotate. By driving the adjusting rod 204c to move, the adjusting rod 204c can drive the adjusting disk 204e to rotate through the insertion rod 204f and the positioning hole 204e-1, so that the adjusting disk 204e drives the threaded column 202c to rotate, thereby adjusting the threaded sleeve 202f on the surface of the threaded column 202c, thereby adjusting the position of the cover plate 201d.

[0049] Example 3, reference Figure 2 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0050] Specifically, the adjusting member 204 also includes a fixed column 204g fixed to one side of the side baffle 201c, the surface of the fixed column 204g is rotatably connected to a connecting gear 204h, a rocker arm 204i is fixed to one side of the connecting gear 204h, the end of the rocker arm 204i is spherically connected to a connecting rod 204j, and the other end of the connecting rod 204j is spherically connected to the end of the adjusting rod 204c.

[0051] The fixed column 204g is used to support the connecting gear 204h. The connecting gear 204h is meshed with the positioning gear 203f, and the radius of the connecting gear 204h is smaller than that of the positioning gear 203f, so that the deflection angle of the connecting gear 204h is greater than that of the positioning gear 203f, so that the connecting gear 204h drives the rocker arm 204i to deflect at a larger angle. Through the spherical connection at both ends of the connecting rod 204j, the rocker arm 204i can pull the adjusting rod 204c when moving, so that the adjusting rod 204c drives the adjusting disk 204e to rotate, so as to adjust the position of the cover plate 201d, thereby adjusting the extrusion force between the scraper 201e and the pressure roller 103.

[0052] Specifically, the main assembly 100 further includes a support wheel 105 rotatably connected to the support base 101 via a rotating shaft, and a pull ring 106 is fixed to one side of the support base 101 .

[0053] By providing the supporting wheel 105 , the staff can easily drag the supporting base 101 through the pull ring 106 .

[0054] In summary, the present invention has the following beneficial effects: 1. It can clean the cement attached to the surface of the roller 103, effectively preventing the cement from being thrown onto the flat road surface, thereby significantly improving the flatness and overall quality of the road; 2. The coordinated work of the scraper 201e and the paving board 203c not only reduces the need for manual intervention, but also speeds up the road paving process, significantly improving construction efficiency; 3. The paving board 203c can monitor the amount of cement accumulated in front of the electric roller in real time, and automatically adjust the pressure of the scraper 201e according to the actual situation, so as to improve the scraping effect of the scraper 201e; 4. Through the feedback of the paving plate 203c, the pressure of the scraper 201e and the fit of the pressure roller 103 can be adjusted, reducing the wear of the pressure roller 103 and the scraper 201e, extending the service life of the equipment, and thus reducing maintenance costs.

[0055] When in use, two workers drag the two support seats 101 in the same direction on both sides of the road respectively, and start the drive motor 104 to make the pressure roller 103 rotate. At this time, as the workers drag, the pressure roller 103 spreads the cement on the road. At the same time, the scraper 201e will clean the cement on the surface of the pressure roller 103 to prevent the pressure roller 103 from throwing the cement onto the already leveled road surface, resulting in a decrease in the leveling effect and affecting the overall quality of the road.

[0056] As the pressure roller 103 moves forward, when cement accumulates in the forward direction of the pressure roller 103, the accumulated cement will squeeze the paving plate 203c, causing the paving plate 203c to deflect upward. At this time, the paving plate 203c can drive the support rod 203a and the positioning gear 203f to rotate, so that the positioning column 203g moves to the other end of the positioning groove 203f-1. At this time, the second spring 203e has a greater elastic force to squeeze the paving plate 203c. When the driving motor 104 drives the pressure roller 103 to rotate, the entire electric roller will vibrate at a higher frequency, causing the paving plate 203c to vibrate at a higher frequency at the same time. At this time, the paving plate 203c presses down on the cement, and at the same time, with its own vibration, it can play the effect of a "vibrator", so that the accumulated cement is spread down.

[0057] When the positioning gear 203f rotates, it can drive the connecting gear 204h to rotate, so that the connecting gear 204h drives the rocker arm 204i to deflect, so that the rocker arm 204i pulls the adjusting rod 204c through the connecting rod 204j, so that the adjusting rod 204c can drive the adjusting disk 204e to rotate through the insert rod 204f and the positioning hole 204e-1, so that the adjusting disk 204e drives the threaded column 202c to rotate, thereby adjusting the threaded sleeve 202f on the surface of the threaded column 202c, thereby adjusting the position of the cover plate 201d, so that the cover plate 201d drives the scraper 201e to squeeze toward the pressure roller 103, so that the extrusion force between the scraper 201e and the pressure roller 103 is increased, thereby enhancing the cleaning effect of the scraper 201e.

[0058] When the cement in front of the pressure roller 103 is spread, the spreading plate 203c is reset under the push of the second spring 203e, and the positioning gear 203f rotates in the opposite direction, which can make the cover plate 201d deflect in the opposite direction, thereby reducing the squeezing force between the scraper 201e and the pressure roller 103, reducing the wear of the pressure roller 103 and the scraper 201e, extending the service life of the equipment, and thus reducing maintenance costs.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
