Description

Technical Field

[0001] The utility model relates to the field of asphalt paving, in particular to an actively heated screed board for asphalt paving. Background Technique

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a highly viscous organic liquid, in a liquid state, with a black surface, and soluble in carbon disulfide. Since asphalt pavements have the advantages of smooth surface, seamless joints, comfortable driving, small vibration, low noise, wear resistance, no dust and easy to clean, short construction period, simple maintenance and repair, renewable utilization and suitable for staged construction, etc., asphalt is commonly used in municipal road construction. During the forming process of asphalt pavements, asphalt needs to be paved first and then compacted. A screed board is required during paving.

[0003] In the existing actively heated screed board for asphalt paving, two electric heating plates are installed on both the side and the bottom of the screed board to heat the asphalt through the electric heating plates. However, when heating the asphalt on the side of the screed board through the electric heating plates on the side, due to a certain distance between the two electric heating plates on the side, it is difficult for the asphalt located between the two electric heating plates to come into contact with the electric heating plates, thereby reducing the heating efficiency of this part of the asphalt, affecting the flow efficiency of this part of the asphalt, and reducing the paving effect of this part of the asphalt. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an actively heated screed board for asphalt paving to solve the technical problem of poor heating effect on the asphalt accumulated between the two electric heating plates.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: An actively heated screed board for asphalt paving, including a screed board, electric heating plates are installed on both the bottom and one side of the screed board, a material pushing assembly is arranged on one side of the screed board, and the material pushing assembly includes a guide rod installed above one side of the screed board, a bracket and two fixing plates installed on the other side of the screed board. A reciprocating lead screw is connected between the two fixing plates through bearings, a movable seat is sleeved on the outer wall of the reciprocating lead screw, and a driven bevel gear is installed at one end of the reciprocating lead screw. A driving motor is installed on the top of the bracket, and the output end of the driving motor is connected with a driving bevel gear. A material pushing plate is sleeved on the outer wall of the guide rod, and a connecting plate is installed between the material pushing plate and the movable seat.

[0006] By adopting the above technical scheme, when the movable seat moves, it will drive the connecting plate to move, and the connecting plate will drive the material pushing plate to move, so that the material pushing plate can push the asphalt close to one side of the screed board to move.

[0007] Further, a limiting rod is arranged between the two fixing plates, and the limiting rod penetrates through the movable seat.

[0008] By adopting the above technical solution, the setting of the limiting rod can guide the movable seat to prevent the movable seat from rotating, thereby improving the stability of the movable seat during movement.

[0009] Furthermore, a push rod is installed on the push flat plate, a battery is installed above the interior of the push rod, and a power cord is provided at the top end of the push rod.

[0010] By adopting the above technical solution, the setting of the push rod is convenient for the staff to hold and facilitates pushing the push flat plate to move.

[0011] Furthermore, an anti-slip sleeve is sleeved on the outer wall of the push rod.

[0012] By adopting the above technical solution, the setting of the anti-slip sleeve enables the staff to stably hold the push rod and prevents the hand from sliding frequently when holding the push rod.

[0013] Furthermore, the movable seat is in threaded connection with the reciprocating lead screw.

[0014] By adopting the above technical solution, after the reciprocating lead screw rotates, it will drive the movable seat to reciprocate, and the movable seat can drive the connecting plate to move.

[0015] Furthermore, the driving bevel gear is meshed with the driven bevel gear, and the diameter of the driving bevel gear is the same as that of the driven bevel gear.

[0016] By adopting the above technical solution, when the driving bevel gear rotates, it will drive the driven bevel gear to rotate, and then drive the reciprocating lead screw to rotate.

[0017] Furthermore, the pushing plate is in sliding connection with the guide rod, and one side of the pushing plate is in contact with the push flat plate.

[0018] By adopting the above technical solution, the guide rod can guide the pushing plate to improve the stability of the pushing plate during movement.

[0019] Furthermore, the push flat plate is in an "L" shape and is made of aluminum alloy material.

[0020] By adopting the above technical solution, the push flat plate can push the asphalt flat, and using aluminum alloy material can reduce the weight of the push flat plate.

[0021] Furthermore, the battery is electrically connected to the drive motor and the electric heating plate respectively.

[0022] By adopting the above technical solution, the storage battery can supply power to the drive motor and the electric heating plate so that the drive motor and the electric heating plate can work.

[0023] Further, a protective cover is installed on the bracket, and the driving motor, the driving bevel gear and the driven bevel gear are all located inside the protective cover.

[0026] In the present utility model, by providing a material pushing assembly, when the pushing plate needs to be used, the driving motor can be started. When the driving motor works, it can drive the driving bevel gear to rotate, which in turn drives the driven bevel gear to rotate, and then drives the reciprocating lead screw to rotate. The reciprocating lead screw drives the movable seat to move reciprocally. When the movable seat moves, it drives the connecting plate to move, and the connecting plate drives the pushing plate to move, so that the pushing plate can push the asphalt near one side of the pushing plate to move, making the asphalt in the middle part near one side of the pushing plate move towards the electric heating plate, facilitating the electric heating plate to heat this part of the asphalt, thereby improving the heating efficiency of the asphalt. At the same time, the reciprocating movement of the pushing plate will push the asphalt accumulated on one side of the pushing plate to move towards the side, facilitating the paving of the asphalt. At the same time, the reciprocating movement of the pushing plate will scrape off the asphalt attached to one side of the pushing plate, improving the cleaning efficiency of one side of the pushing plate and preventing some asphalt from remaining on the side of the pushing plate all the time.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0035] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0036] Embodiment 1:

[0037] The asphalt paving active heating type screed board, as Figures 1 - 6 shown, includes a screed board 1. Electric heating plates 2 are installed at the bottom and one side of the screed board 1. A material pushing assembly 6 is arranged on one side of the screed board 1. A push rod 3 is installed on the screed board 1. A battery 4 is installed above the interior of the push rod 3. A power cord 5 is arranged at the top of the push rod 3. The arrangement of the push rod 3 facilitates the staff to hold and conveniently push the screed board 1 to move. The screed board 1 is in an "L" shape and is made of aluminum alloy material. The screed board 1 can level the asphalt, and using aluminum alloy material can reduce the weight of the screed board 1.

[0038] Specifically, the material pushing assembly 6 includes a guide rod 604 installed above one side of the screed board 1, a bracket 601 installed on the other side of the screed board 1, and two fixing plates 606. A reciprocating lead screw 607 is connected between the two fixing plates 606 through bearings. A movable seat 609 is sleeved on the outer wall of the reciprocating lead screw 607. One end of the reciprocating lead screw 607 is provided with a driven bevel gear 608. A driving motor 602 is installed on the top of the bracket 601. The output end of the driving motor 602 is connected with a driving bevel gear 611. The battery 4 is electrically connected to the driving motor 602 and the electric heating plate 2 respectively. The storage battery 4 can supply power to the driving motor 602 and the electric heating plate 2 so that the driving motor 602 and the electric heating plate 2 can work.

[0039] Specifically, the driving bevel gear 611 meshes with the driven bevel gear 608. The diameter of the driving bevel gear 611 is the same as that of the driven bevel gear 608. When the driving bevel gear 611 rotates, it drives the driven bevel gear 608 to rotate, thereby driving the reciprocating lead screw 607 to rotate. A pushing plate 603 is sleeved on the outer wall of the guide rod 604. The pushing plate 603 is slidably connected to the guide rod 604. One side of the pushing plate 603 contacts the pushing flat plate 1. The guide rod 604 can guide the pushing plate 603 to improve the stability of the pushing plate 603 when it moves. A connecting plate 605 is installed between the pushing plate 603 and the movable seat 609. When the movable seat 609 moves, it drives the connecting plate 605 to move, and the connecting plate 605 drives the pushing plate 603 to move, so that the pushing plate 603 can push the asphalt near the side of the pushing flat plate 1 to move. The movable seat 609 is threadedly connected to the reciprocating lead screw 607. After the reciprocating lead screw 607 rotates, it drives the movable seat 609 to reciprocate. The movable seat 609 can drive the connecting plate 605 to move. A protective cover 8 is installed on the bracket 601. The driving motor 602, the driving bevel gear 611 and the driven bevel gear 608 are all located inside the protective cover 8. The protective cover 8 can shield and protect the driving bevel gear 611 and the driven bevel gear 608.

[0040] Embodiment Two:

[0041] Based on the above Embodiment One, since the reciprocating lead screw 607 drives the movable seat 609 to move when it rotates, in order to prevent the movable seat 609 from rotating with the reciprocating lead screw 607, the movable seat 609 needs to be guided. Therefore, the following structure is set up.

[0042] Refer to Figures 1 - 4 , a limiting rod 610 is arranged between two fixing plates 606. The limiting rod 610 penetrates through the movable seat 609. The arrangement of the limiting rod 610 can guide the movable seat 609 to prevent the movable seat 609 from rotating, thereby improving the stability of the movable seat 609 when it moves.

[0043] Embodiment Three:

[0044] Based on the above Embodiment One, in order to improve the stability of the staff's hand holding the push rod 3, the following structure is set up.

[0045] Refer to Figures 1 - 2 , an anti-slip sleeve 7 is sleeved on the outer wall of the push rod 3. The arrangement of the anti-slip sleeve 7 facilitates the staff to stably hold the push rod 3 and prevents the hand from sliding frequently when holding the push rod 3.

[0046] The working principle of the present utility model is as follows: First, when the pushing plate 1 needs to be used, the driving motor 602 and the electric heating plate 2 can be started, and the pushing plate 1 is pushed to move through the push rod 3, so that the pushing plate 1 can push the asphalt to move, facilitating the paving of the asphalt. Moreover, when the electric heating plate 2 works, it can heat the adjacent asphalt. When the driving motor 602 works, it can drive the driving bevel gear 611 to rotate, thereby driving the driven bevel gear 608 to rotate, and then driving the reciprocating lead screw 607 to rotate. The reciprocating lead screw 607 drives the movable seat 609 to reciprocate. When the movable seat 609 moves, it drives the connecting plate 605 to move, and the connecting plate 605 drives the pushing plate 603 to move, so that the pushing plate 603 can push the asphalt on one side close to the pushing plate 1 to move, enabling the asphalt in the middle part on one side close to the pushing plate 1 to move towards the electric heating plate 2, facilitating the electric heating plate 2 to heat this part of the asphalt. At the same time, the reciprocating movement of the pushing plate 603 will push the excess asphalt accumulated on one side of the pushing plate 1 to move towards the side, facilitating the paving of the asphalt. At the same time, the reciprocating movement of the pushing plate 603 will scrape off the asphalt attached to one side of the pushing plate 1.

[0047] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and do not limit the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
