Detailed Implementation

[0026] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, this embodiment designs a raw material mixing roller mechanism for asphalt concrete, including raw material burner 1, raw material roller body 5, and supporting rollers 7, etc.

[0029] The virgin material roller body 5 includes components such as a front conical section, a roller section, and a rear conical section. The roller section is a hollow cylindrical structure; the front conical section tapers from back to front and is connected to the front side of the roller section. The front conical section flares from back to front and is connected to the rear side of the roller section. The rear end of the virgin material roller body 5 is provided with a virgin rear cylinder opening, and the front end of the virgin material roller body 5 is provided with a virgin front cylinder opening. The virgin rear cylinder opening is located at the rear end of the rear conical section, and the virgin front cylinder opening is located at the front end of the front conical section.

[0030] A raw material burner 1 is connected to the inlet of the raw material rear cylinder to heat the raw asphalt concrete raw material inside the burner 1. Specifically, a transfer cylinder 2 is fixedly connected to the inlet of the raw material rear cylinder. The transfer cylinder 2 is cylindrical and coaxial with the raw material roller body 5. The outlet of the raw material burner 1 is tubular and inserted into the transfer cylinder 2. The transfer cylinder 2 can rotate relative to the inlet of the raw material rear cylinder. The raw material burner 1 is equipped with an air inlet and a gas interface. The gas is burned inside the raw material burner 1 and mixed with air to form hot air, which is then sent into the raw material roller body 5 through the transfer cylinder 2.

[0031] A roller ring rail 3 is provided outside the raw material roller body 5. Generally, two roller ring rails 3, one in front and one behind, are connected to the raw material roller body 5. The roller ring rail 3 is coaxial with the raw material roller body 5 and is fixed relative to it. The raw material roller body 5 is horizontally arranged above the support rollers 7, and multiple support rollers 7 are in contact with the roller ring rail 3 and support the raw material roller body 5. Each roller ring rail 3 can be supported by two support rollers 7, one on the left and one on the right.

[0032] A support plate 4 is provided between the inner wall of the roller ring rail 3 and the outer wall of the raw material roller body 5. The support plate 4 is inclined to the radial direction of the roller ring rail 3. The outer end of the support plate 4 is fixedly connected to the roller ring rail 3, and the inner end of the support plate 4 abuts against the raw material roller body 5.

[0033] A plurality of agitating blades 10 are provided on the inner wall of the raw material roller body 5. The agitating blades 10 can be arranged in a stepped manner in the length and height directions of the raw material roller body 5. The agitating blades 10 are used to agitate the raw material of asphalt concrete. The agitating blades 10 are distributed in the roller section.

[0034] The inner wall of the raw material roller body 5 is also provided with several guide vanes 11. The guide vanes 11 extend from the roller section to the front cone section. The guide vanes 11 are inclined in the circumferential and axial directions of the raw material roller body 5. The guide vanes 11 are used to guide the raw material forward or backward. The guide vanes 11 are used for adding raw material to asphalt concrete or for delivering asphalt concrete.

[0035] A raw material hopper 8 is provided at the upper half of the raw material inlet, which is used to guide the raw material of asphalt concrete into the raw material roller body 5. The lower half of the raw material inlet forms a raw material outlet 9, which is used to discharge the asphalt concrete from the raw material roller body 5.

[0036] The support rollers 7 are rotatably mounted on the support base 6, and the number of support rollers 7 corresponds one-to-one with the number of support bases 6. At least one support roller 7 is connected to a mixing motor. When the mixing motor rotates, it drives the support rollers 7, and the support rollers 7 drive the raw material roller body 5 to rotate under the action of friction, thereby realizing the mixing of the raw material of asphalt concrete.

[0037] When the raw material mixing roller mechanism in this embodiment is in use:

[0038] The raw material of asphalt concrete is fed into the raw material roller body 5 from the raw material inlet through the raw material hopper 8. The raw material roller body 5 rotates forward under the drive of the mixing motor, thereby guiding the raw material of asphalt concrete backward and tumbling and mixing it under the combined action of the guide blades 11 and the tumbling blades 10. During this process, the raw material burner 1 sends heated air into the raw material roller body 5 to heat the raw material of asphalt concrete, thereby ensuring the fluidity of the raw material of asphalt concrete.

[0039] After the asphalt concrete is mixed, the main body 5 of the raw material roller rotates in the opposite direction under the drive of the mixing motor. The guide blades 11 guide the asphalt concrete forward, so that the asphalt concrete is discharged outward from the raw material outlet 9 at the front of the raw material roller. After it is completely discharged, a new round of asphalt concrete mixing can be carried out.

[0040] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
