Technical Field

[0001] The utility model relates to the field of asphalt sampling devices, in particular to an asphalt hot bin sampling device. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives, mainly used in industries such as coatings, plastics, rubbers, etc. and for paving roads. The asphalt hot bin is used to store heated asphalt aggregates.

[0003] A Chinese patent with the related publication number CN215448579U discloses an asphalt mixing plant hot bin sampling device, which includes a bracket, a bin clamped by the bracket, and a discharge port at the bottom of the bin. It also includes a height adjustment assembly below the discharge port and a horizontal adjustment assembly at the bottom of the height adjustment assembly.

[0004] In view of the above related technologies, the existing asphalt hot bin sampling device directly receives materials below the discharge port of the hot bin through a sampling hopper. The viscous or solid asphalt, liquid asphalt, and asphalt emulsion stored in the asphalt hot bin are directly discharged into the sampling hopper. After a certain amount of liquid asphalt and asphalt emulsion accumulate in the sampling hopper, the asphalt particles discharged from the hot bin discharge port falling into the sampling hopper easily cause the liquid asphalt or asphalt emulsion to splash, resulting in waste of asphalt samples and posing a risk of scalding the staff. In summary, the existing asphalt hot bin sampling device has the problem of being difficult to sample stably. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide an asphalt hot bin sampling device to solve the technical problem that the existing asphalt hot bin sampling device is difficult to sample stably.

[0007] By adopting the above technical solution, the separation hopper is used to separate solid asphalt and liquid asphalt, separating and collecting the liquid asphalt and solid asphalt at the same time, preventing the solid asphalt from falling into the liquid asphalt and splashing the liquid asphalt, effectively improving the stability of the sampling process of the asphalt hot bin sampling device.

[0008] The utility model is further arranged such that one side wall of the aggregate hopper is orthogonal to the ground and fixedly connected with a rotating column, the rotating column is rotatably connected to the outer wall of the bottom end of the discharge port of the asphalt hot material bin, and the remaining three side walls of the aggregate hopper are all inclined inwards.

[0009] By adopting the above technical scheme, the aggregate hopper can be located below the discharge port of the asphalt hot material bin to collect asphalt samples.

[0010] The utility model is further arranged such that the outer wall of the separation hopper is in contact with the inner wall of the aggregate hopper.

[0011] By adopting the above technical scheme, the separation hopper can be stably placed inside the aggregate hopper.

[0012] The utility model is further arranged such that a pull ring is fixedly connected to the bottom end of the separation hopper in a direction away from the rotating column.

[0013] By adopting the above technical scheme, it is convenient for the staff to separately take out the solid asphalt after the sampling work is completed.

[0014] The utility model is further arranged such that the top surface of the aggregate hopper faces the discharge port of the asphalt hot material bin, and the projected area of the top surface of the separation hopper facing the ground is larger than the discharge port of the asphalt hot material bin.

[0015] By adopting the above technical scheme, it is prevented that when the sample is discharged from the discharge port of the asphalt hot material bin, it directly discharges outside the accommodation space of the separation hopper.

[0016] The utility model is further arranged such that no filter holes are provided on the side walls of the separation hopper.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.

[0028] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0029] Embodiment 1

[0030] An asphalt hot aggregate bin sampling device, as Figures 1-4 shown, includes an aggregate hopper 1, the aggregate hopper 1 is rotatably connected to the bottom end of the discharge port of the asphalt hot aggregate bin. Specifically, the discharge port of the asphalt hot aggregate bin is specifically the discharge port 11. A bearing strip 8 is fixedly connected to the inner wall of the aggregate hopper 1, and a separation hopper 6 is placed on the bearing strip 8. The separation hopper 6 is provided with filter holes on the bottom surface. A collection tank 9 is installed at the bottom end of the aggregate hopper 1. The collection tank 9 is communicated with the aggregate hopper 1 through a pipeline. A drain port 10 is connected to the bottom end of the collection tank 9, and a valve is provided at the drain port 10. One side wall of the aggregate hopper 1 is orthogonal to the ground and fixedly connected with a rotating column 2. The rotating column 2 is rotatably connected to the outer wall of the bottom end of the discharge port of the asphalt hot aggregate bin. Specifically, a fixed cylinder 3 is fixedly connected to the side wall of the discharge port 11. The rotating column 2 passes through the fixed cylinder 3 and is connected with a transmission belt. A driving motor 4 is fixedly connected to the side wall of the discharge port 11 on one side of the fixed cylinder 3. The output end of the driving motor 4 is also connected with a transmission belt. The other three side walls of the aggregate hopper 1 are all inclined inward, so that the aggregate hopper 1 can be located below the discharge port of the asphalt hot aggregate bin to collect asphalt samples, and can also rotate away from below the discharge port of the asphalt hot aggregate bin to facilitate the staff to take out the asphalt samples.

[0031] Please refer to Figures 1-3, the top surface of the aggregate hopper 1 faces the discharge port of the asphalt hot material bin. The projected area of the top surface of the separation hopper 6 facing the ground is larger than the discharge port of the asphalt hot material bin, preventing the samples discharged from the discharge port of the asphalt hot material bin from directly discharging outside the accommodation space of the separation hopper 6, enabling the separation hopper 6 to stably accommodate the samples discharged from the asphalt hot material bin. The outer wall of the separation hopper 6 is in contact with the inner wall of the aggregate hopper 1, enabling the separation hopper 6 to be stably placed inside the aggregate hopper 1 and avoiding the shaking of the separation hopper 6 caused by the falling of solid asphalt. No filter holes are provided on the side walls of the separation hopper 6. When the separation hopper 6 is pulled out and placed on the edge of the aggregate hopper 1, the liquid asphalt in the separation hopper 6 can further flow out of the separation hopper 6 and flow down along the inner wall of the aggregate hopper 1, further separating the liquid asphalt from the solid asphalt and effectively preventing the liquid asphalt from spilling. The bottom surface of the separation hopper 6 does not contact the bottom surface of the aggregate hopper 1, creating a space inside the aggregate hopper 1 for temporarily storing liquid asphalt and avoiding the situation where the liquid asphalt overflows before it can flow into the collection tank 9.

[0032] Embodiment 2

[0033] An asphalt hot material bin sampling device, as Figures 1-4 shown. Based on Embodiment 1, the difference from Embodiment 1 is that a pull ring 7 is fixedly connected to the bottom end of the separation hopper 6 in the direction away from the rotating column 2. The pull ring 7 is used to conveniently pull out the separation hopper 6, facilitating the staff to separately take out the solid asphalt after the sampling work is completed. A blocking piece 5 is fixedly connected to the side wall adjacent to the fixed cylinder 3 of the discharge port 11. The blocking piece 5 is used to block the rotation of the aggregate hopper 1, enabling the aggregate hopper 1 to quickly stop after rotating in place and avoiding the continuous rotation of the aggregate hopper 1 after it rotates below the discharge port 11, effectively improving the accuracy of the rotational adjustment of the aggregate hopper 1.

[0034] The working principle of the present utility model is as follows: The driving motor 4 operates to rotate the aggregate hopper 1 below the discharge port 11. The discharge port 11 of the asphalt hot material bin discharges materials, and both solid asphalt and liquid asphalt fall into the separation hopper 6 at the same time. The solid asphalt therein is intercepted by the separation hopper 6, while the liquid asphalt flows into the collection tank 9 through the filter holes on the bottom surface of the separation hopper 6. After completing a sampling work, the driving motor 4 operates to rotate the aggregate hopper 1 away from below the discharge port 11. First, open the liquid discharge port 10 to discharge the liquid asphalt in the collection tank 9 into the transfer container. After the temperature of the solid asphalt in the separation hopper 6 decreases, then pull the pull ring 7 to lift the separation hopper 6 and place it on the edge of the aggregate hopper 1. At this time, the filter holes on the bottom surface of the separation hopper 6 still face the inner wall of the aggregate hopper 1. After the liquid asphalt in the separation hopper 6 has drained, the separation hopper 6 can be removed, and the solid asphalt in the separation hopper 6 can be conveniently taken out.

[0035] Although embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and are not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present utility model, make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed. However, as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
