Description

Technical Field

[0001] The present application relates to the field of road construction equipment, and in particular to an asphalt road surface leveling device for highway engineering. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable and durable. Therefore, asphalt pavement is a high-grade pavement widely used in road construction.

[0003] Asphalt pavement construction requires flattening operations. During the flattening process, excess asphalt materials on the raised parts of the road surface will be piled on both sides of the road. The staff will then collect the excess asphalt materials, which increases the labor burden of the staff. The excess asphalt materials cannot be used to fill the depressions on the road surface, resulting in a waste of asphalt materials.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the excess asphalt material during the leveling process cannot be collected in time and used to fill road depressions during the leveling process, thereby increasing the labor burden of the staff and causing waste of asphalt materials. Utility Model Content

[0006] The present application provides an asphalt pavement leveling device for highway engineering, which adopts the following technical solution:

[0007] An asphalt pavement leveling device for highway engineering comprises a base, wheels and a push-pull handle arranged on the base, a material storage box arranged on the base, a filling component connected to the material storage box, a mounting frame and a collecting component arranged on the base; the collecting component comprises an electric telescopic rod connected to the mounting frame, a mounting block connected to one end of the electric telescopic rod away from the mounting frame, a first transmission motor and a scraper arranged on the mounting block, the scraper is fixedly connected to the transmission shaft of the first transmission motor, and a feed port is opened on the material storage box.

[0008] By adopting the above technical solution, the operator pushes the base to move by pushing and pulling the handle, and the scraper scrapes the asphalt pavement flat, and the excess asphalt material is scraped onto the scraper. The electric telescopic rod drives the mounting block and the scraper to move away from the ground, and then the first transmission motor drives the scraper to rotate, so that the scraper is tilted, which is convenient for dumping the excess asphalt material into the storage box through the feed port.

[0009] Preferably, a material guiding slope is provided at one end of the scraper away from the base.

[0010] By adopting the above technical solution, the setting of the material guide slope makes it easier for excess asphalt material to be scraped onto the scraper, which is beneficial to improving the collection efficiency of excess asphalt material.

[0011] Preferably, the scraper is provided with a first baffle and a second baffle, the number of the first baffles is two, the two first baffles are respectively arranged on the opposite sides of the scraper away from the material guide slope, and a control component is provided on the side of one of the first baffles close to the base, and the control component is connected to the second baffle.

[0012] By adopting the above technical solution, the arrangement of the first baffle and the second baffle reduces the phenomenon of asphalt material overflowing from the edge of the scraper, thereby improving the safety of the asphalt material collection process.

[0013] Preferably, the control assembly includes a second transmission motor disposed on the first baffle, a transmission shaft of the second transmission motor is fixedly connected to the second baffle, and a side of the second baffle away from the second transmission motor is rotationally connected to the first baffle.

[0014] By adopting the above technical solution, when it is necessary to dump the excess asphalt material collected on the scraper into the storage box, the second transmission motor drives the second baffle to rotate, and the second baffle scrapes the excess asphalt material off the scraper, so that the excess asphalt material falls into the storage box, thereby improving the collection efficiency of the asphalt material.

[0015] Preferably, a material guide plate is provided in the feed port, and the material guide plate is inclined, with one end of the material guide plate away from the feed port being inclined in a direction away from the ground.

[0016] By adopting the above technical solution, the inclined guide plate facilitates the asphalt material to enter the storage box through the feed port, reduces the phenomenon of asphalt material spilling outside the storage box, and reduces the phenomenon of asphalt material clogging at the feed port.

[0017] Preferably, protective baffles are provided on opposite sides of the material guide plate.

[0018] By adopting the above technical solution, the provision of the protective baffle reduces the phenomenon of asphalt material overflowing from both sides of the guide plate, thereby improving the safety of collecting asphalt materials.

[0019] Preferably, a heating element is provided in the storage box.

[0020] By adopting the above technical solution, the heating element heats the excess asphalt material collected in the storage box to keep it in a fluid state, thereby facilitating filling of road depressions.

[0021] Preferably, the filling assembly includes a feed pump disposed on the base, a feed pipe connected to the discharge end of the feed pump, and a valve disposed on the feed pipe, and the feed end of the feed pump is connected to the storage box.

[0022] By adopting the above technical solution, the feed pump transports the asphalt material collected in the storage box to the feed pipe, and the road depression can be filled by opening the valve.

[0023] Preferably, an end of the feed pipe away from the feed pump is connected to a guide pipe, and a diameter of the end of the guide pipe away from the feed pipe is smaller than a diameter of an end of the guide pipe close to the feed pipe.

[0024] By adopting the above technical solution, the shrinkage structure of the guide pipe makes the asphalt material more uniform during filling, thereby improving the filling quality.

[0025] In summary, this application has the following beneficial technical effects:

[0026] 1. Through the cooperation of the scraper, the first transmission motor and the electric telescopic rod, the excess asphalt material can be effectively collected, and the excess asphalt material can be used to fill the road surface depressions through the heating element and the filling component, thereby improving the road surface leveling efficiency and the utilization rate of the asphalt material;

[0027] 2. The provision of the first baffle and the second baffle improves the safety of the asphalt material collection process. The second baffle pushes the asphalt material to slide off the scraper during rotation, thereby improving the collection efficiency of the asphalt material. BRIEF DESCRIPTION OF THE DRAWINGS
