[0002] Modified asphalt is an asphalt binder made by adding external additives (modifiers) such as rubber, resin, high molecular polymer, ground rubber powder or other fillers, or taking measures such as mild oxidation processing of asphalt to improve the performance of asphalt or asphalt mixture. There are two mechanisms for modifying asphalt: one is to change the chemical composition of asphalt, and the other is to make the modifier evenly distributed in the asphalt to form a certain spatial network structure.

A weighing module 8 fixedly connected to the mounting frame 6 is attached to the side of the first hopper 7, and a silo spiral outlet 9 is provided at the bottom of the first hopper 7. A second hopper 14 is provided on one side of the first hopper 7, a third hopper 15 is provided on one side of the second hopper 14, and a fourth hopper 16 is provided on one side of the third hopper 15.

[0024] In this embodiment, the discharge port of the ton bag breaker 2 corresponds to the feed port of the bucket elevator 3 , so that the material discharged from the ton bag breaker 2 can enter the bucket elevator 3 .

[0025] In this embodiment, the discharge ports of one group of pneumatic three-way valves 5 correspond to the first hopper 7 and the second hopper 14 respectively, and the discharge ports of the other group of pneumatic three-way valves 5 correspond to the third hopper 15 and the fourth hopper 16 respectively. When the material in the discharge port 4 reaches the system set weight value, the pneumatic three-way valve 5 switches direction, and the original connection with the first hopper 7 is changed to the second hopper 14 (the original connection with the third hopper 15 is changed to the fourth hopper 16). After the three-way valve is switched, the material in the first hopper 7 is transported to the inlet flange 10 through the spiral silo outlet, enters the rubber powder spiral feeder 12 through the inlet flange 10, and finally flows from the raw material outlet 13 to the next link in the production process.

[0026] In this embodiment, four groups of card slots are equidistantly arranged on the top of the mounting frame 6, and the first hopper 7, the second hopper 14, the third hopper 15 and the fourth hopper 16 are respectively embedded in the card slots and fit tightly therewith, so that the mounting frame 6 can cooperate with the card slots to limit the first hopper 7, the second hopper 14, the third hopper 15 and the fourth hopper 16.

[0027] In this embodiment, weighing modules 8 are provided on the sides of the first hopper 7, the second hopper 14, the third hopper 15 and the fourth hopper 16. By providing the weighing modules 8, the materials discharged from the discharge port 4 into the hopper can be weighed.

[0028] In this embodiment, the first hopper 7 and the second hopper 14 contain rubber powder, and the third hopper 15 and the fourth hopper 16 contain SBS, so that different materials can be transported in different categories. Example

[0029] On the basis of Example 1, a preferred embodiment of a continuously working feeding device provided by the present invention is as follows: Figures 1 to 4 As shown: the top of the base 1 is fixedly connected to a first fixed plate 11, the top of the first fixed plate 11 is fixedly connected to a rubber powder spiral feeder 12, the bottom of the rubber powder spiral feeder 12 is fixedly connected to a raw material outlet 13, one side of the raw material outlet 13 is provided with an inlet flange 10 located at the top of the rubber powder spiral feeder 12, one side of the first fixed plate 11 is provided with a second fixed plate 18 fixedly connected to the base 1, the top of the second fixed plate 18 is fixedly connected to the SBS spiral feeder 17

[0030] In this embodiment, the bottom of the first hopper 7, the second hopper 14, the third hopper 15 and the fourth hopper 16 are all provided with a silo spiral outlet 9, which is communicated with the inlet flange 10. The material is transported to the inlet flange 10 through the spiral silo outlet, enters the rubber powder spiral feeder 12 through the inlet flange 10, and finally flows from the raw material outlet 13 to each link in the production process.

[0031] The working principle and use process of the utility model are as follows: First, since SBS and rubber powder are easily affected by moisture and agglomerate during storage, the raw materials SBS and rubber powder are crushed into uniform and fine particles by two ton bag breakers 2. The crushed materials are respectively sent to the first hopper 7, the second hopper 14 and the fourth hopper 16 by two bucket elevators 3. Among them, the first hopper 7, the second hopper 14 and the fourth hopper 16 contain rubber powder, and the third hopper 15 and the fourth hopper contain SBS. The discharge outlets 4 of the two bucket elevators 3 are both equipped with pneumatic three-way valves 5, the two outlets of one pneumatic three-way valve 5 correspond to the first hopper 7 and the second hopper 14 respectively, and the outlet of the other pneumatic three-way valve 5 corresponds to the third hopper 15 and the fourth hopper respectively. The pneumatic three-way valve 5 controls the material from the discharge outlet 4 on the bucket elevator 3 to be connected with one of the first hopper 7 and the second hopper 14 (the third hopper 15 and the fourth hopper 16) through the cylinder. When the material in the discharge outlet 4 reaches the system set weight When the weighing value is reached, the pneumatic three-way valve 5 is reversed, and the original connection with the first hopper 7 is changed to the second hopper 14 (the original connection with the third hopper 15 is changed to the fourth hopper 16). After the three-way valve is reversed, the material in the first hopper 7 is transported to the inlet flange 10 through the spiral silo outlet, and enters the rubber powder screw feeder 12 through the inlet flange 10, and finally flows from the raw material outlet 13 to the next link in the production process. In this process, due to the pneumatic three-way valve 5 and the second hopper 14, the second hopper 14 begins to feed. When the material in the first hopper 7 is transported, the material in the second hopper 14 also reaches the weighing set value. The pneumatic three-way valve 5 is reversed again, and the rubber powder in the second hopper 14 begins to be transported to the raw material outlet 13 through the spiral silo outlet and the inlet flange 10 rubber powder screw feeder. In this way, during the whole process, the SBS material will be continuously transported to the SBS screw feeder 17, and discharged from the raw material outlet 13 of the SBS screw feeder 17 to the next link in the production process.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
