Background Art

[0002] Asphalt concrete is often used in rail foundation engineering and road engineering. However, during the transportation of asphalt concrete, adhesion often occurs. The asphalt concrete adhered to the transport vehicle is difficult to unload from the transport compartment, and it is difficult to remove it after it is adhered to the transport compartment.

[0003] In addition, even if the asphalt concrete does not stick to the inner wall of the transport compartment, due to the viscosity of the asphalt itself, the asphalt concrete is easy to stick together. When the asphalt concrete is transported to the rear of the transport compartment, the stuck asphalt concrete is fixed together, affecting the subsequent use of the asphalt concrete and making it inconvenient to unload the asphalt concrete. Summary of the Invention

[0031] Example 1

[0032] This embodiment provides an asphalt concrete transport device for facilitating unloading. The asphalt concrete transport device includes a transport compartment, a conveyor belt disposed within the transport compartment, and a first drive device connected to the conveyor belt for forward and backward motion. During unloading, the first drive device drives the conveyor belt backward, simultaneously driving the asphalt concrete on the conveyor belt backward, thereby unloading the asphalt concrete. A baffle is also provided at the front end of the conveyor belt. The movement of the baffle and the conveyor belt together propel the asphalt concrete back and forth within the transport compartment, thereby unloading the material. At the rear of the transport compartment, at least one fixed shaft 3 is disposed. A rotating shaft is disposed on the fixed shaft 3. In this embodiment, the rotating shaft is a sleeve 5 that is sleeved onto the fixed shaft 3 and rotates about the fixed shaft 3. The rotating shaft is connected to a motor 4 for driving rotation thereof, and the rotating shaft rotates electrically. The rotating shaft is provided with an outwardly extending protrusion. The protrusion can be in the form of a rod or a plate. The protrusion rotates with the rotation of the shaft, thereby moving the asphalt concrete within the transport compartment.

[0033] The above-mentioned asphalt concrete transport device which is convenient for unloading is provided with at least one fixed shaft 3 at the rear of the transport compartment, and a rotating shaft and a protrusion are provided on each fixed shaft 3. The rotating shaft and the protrusion rotate under the drive of the motor 4. When the rotating shaft and the protrusion rotate, a rotating device is formed at the rear of the transport compartment. The rotating shaft and the protrusion, especially the protrusion, pull the asphalt concrete during rotation, so that the large pieces of asphalt concrete that are stuck together are separated into multiple pieces, and the separated small pieces of asphalt concrete are pulled out of the transport compartment, thereby realizing the unloading of the asphalt concrete and the separation of large pieces of asphalt concrete, avoiding the problem that large pieces of asphalt concrete cannot be unloaded and the asphalt concrete is stuck together and cannot be used directly.

[0034] Specifically, in this embodiment, the asphalt concrete transport device further includes a heating device, the heating end of which is located on the rotating shaft or the protruding member. By heating the rotating shaft or the protruding member with the heating end, the asphalt concrete can be heated when the protruding member moves the asphalt concrete, thereby reducing the hardness of the asphalt concrete. This facilitates the movement of the asphalt concrete by the protruding member, allowing small pieces of asphalt concrete to be removed from larger pieces of adhered asphalt concrete.

[0035] More specifically, in this embodiment, a specific implementation of the heating device is also provided. The heating device is a battery and a heating rod, and the heating rod is fixed on the protrusion.

[0036] More specifically, in this embodiment, a specific form of the protrusion is provided: the protrusion is a tooth rake or a spiral blade 6 provided on the rotating shaft. When the protrusion is a tooth rake, the tooth rake is rod-shaped and extends outward; when the protrusion is a spiral blade 6, the protrusion is distributed on the rotating shaft in a spiral shape.

[0037] Specifically, in this embodiment, in order to increase the working range of the protruding member and enable the protruding member to separate and move asphalt concrete at different heights, the inner side wall 8 of the transport compartment is provided with a guide groove 7 extending backward and downward from the upper rear end. The guide grooves 7 correspond to each other and are respectively located on both sides of the inner side wall 8 of the transport compartment, and the two arc-shaped corresponding guide grooves 7 correspond to the fixed shaft 3. The two ends of the fixed shaft 3 are respectively inserted into the guide grooves 7 on both sides, and the fixed shaft 3 moves up and down in the guide grooves 7. When the asphalt concrete is at a higher position, it will push the fixed shaft 3 to move obliquely upward along the guide groove 7. As the protruding member separates and moves the asphalt concrete, the height of the asphalt concrete gradually decreases. The fixed shaft 3 automatically moves downward under the action of gravity, thereby achieving the separation of the protruding member and the movement of asphalt concrete at different heights.

[0038] More specifically, in this embodiment, in order to reduce the movement resistance of the fixed shaft 3 , bearing wheels are installed at both ends of the fixed shaft 3 , and the bearing wheels are clamped into the guide grooves 7 .

[0039] More specifically, in order to improve the convenience of unloading and make the unloaded goods concentrated in the middle or spread to both sides, in this embodiment, the spiral blade 6 includes a left spiral blade 6 located on the left and a right spiral blade 6 located on the right, and the left spiral blade 6 and the right spiral blade 6 have opposite rotation directions. Through the setting of the rotation directions of the spiral blades 6 on both sides, the left spiral blade 6 and the right spiral blade 6 can be separated and transported to the middle of the asphalt concrete to prevent the accumulation of asphalt concrete; of course, the asphalt concrete can also be separated and transported to both sides when rotating in the opposite direction.

[0040] Specifically, in order to make each fixed shaft 3 and the rotating shaft and motor 4 thereon cooperate, and make the protrusions on each rotating shaft cooperate to separate and move the asphalt concrete, the above-mentioned fixed shaft 3 is provided in plurality and distributed one by one from the upper rear end of the transport compartment downward to the rear.

[0041] Example 2:

[0042] Example 2 is a further improvement of the asphalt concrete transport device provided on the basis of Example 1. In this example, the further improvement is mainly to prevent the asphalt concrete from adhering to the inner wall of the transport compartment. In this example, the anti-sticking agent can be sprayed onto the inner wall of the transport compartment manually or mechanically. In this example, to enhance the effectiveness of the anti-sticking agent: an oil pipe 2 is provided at the upper end of the inner wall 8 of the transport compartment, and the oil pipe 2 is connected to the liquid barrel; a film tube 9 is provided at the lower portion of the oil pipe 2, and a plastic film 1 is wrapped around the film tube 9; and an oil outlet is provided on the oil pipe 2, facing the side of the plastic film 1 close to the inner wall of the transport compartment. During specific use, the anti-adhesive agent is first sprayed onto the inner sidewall 8 of the transport compartment. The film tube 9 is then rotated to release the plastic film 1 so that the plastic film 1 covers the inner sidewall 8 of the transport compartment with the anti-adhesive agent. At this time, the anti-adhesive agent can be easily fixed to the plastic film. In addition, the above-mentioned setting of the plastic film 1 can make the anti-adhesive agent flow finely and be evenly distributed in the space between the plastic film 1 and the inner sidewall 8 of the transport compartment. At the same time, the plastic film 1 can also prevent the anti-adhesive agent from evaporating too quickly. In addition, as needed, the anti-adhesive agent can be sprayed onto the outer surface of the plastic film 1 to increase the anti-adhesive agent content. Finally, after the asphalt concrete is loaded, since the oil outlet is located at the upper position between the plastic film and the inner sidewall of the transport compartment, the anti-adhesive agent can be dripped into the space between the plastic film 1 and the inner sidewall 8 of the transport compartment through the oil outlet. Under the capillary action, the anti-adhesive agent can flow evenly downward and prevent the anti-adhesive agent added later from directly flowing into the asphalt concrete.

[0043] Of course, the above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention and should be protected by the present invention.
