[0002] At present, separation and regeneration of waste asphalt pavement materials is a highly efficient and socially and economically beneficial RAP utilization method. However, in many existing separation devices, before the waste asphalt pavement materials are transported by the conveying device, the waste asphalt pavement materials are first discharged to the material bin by the loader. However, since there are large particles in the waste asphalt pavement materials, when they pass through the material bin and enter the conveying device, large pieces of waste asphalt pavement materials will block the discharge port of the material bin, thereby affecting the discharge effect of the material bin.

[0003] Based on this, a material bin with screening function is studied. The waste asphalt pavement materials entering the material bin are first screened to obtain screened materials and unscreened materials respectively, and the materials are discharged through different discharge ports to avoid clogging the bin, affecting the discharge effect, and reducing the separation effect.

[0019] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figure 1 As shown, the material bin of this embodiment 1 includes a bin body 1 with a screen 2 inside, and a screening outlet is opened at the bottom of the bin body 1, and the waste asphalt pavement material entering the bin body 1 is initially screened by the screen 2, and the screened material obtained enters the conveying device through the screening outlet and is transmitted to the next process. The screen 2 covers the inside of the bin body 1 and is tilted downward, and the end of the bin body 1 corresponding to its tilted setting is set as a discharge port, that is, the large block asphalt recycled material that has not been screened can enter another conveying device through the discharge port and be transmitted to the next process.

[0022] The screen 2 is connected to the warehouse body 1 through the vibration screen spring 3, and a vibrator 10 can be set on the screen 2, and the vibrator 10 can be directly purchased from the market. Through the combined action of the vibrator 10 and the vibration screen spring 3, the screen 2 in the warehouse body 1 can achieve vibration screening operation. The vibrator 10 can be directly set on the screen 2 or installed by means of a connecting plate 8 across the warehouse body 1, and the connecting plate 8 can be fitted with the screen 2 to achieve the screening operation of the screen 2. The vibration screen spring 3 can be set into four groups, respectively located at the four corners of the screen 2. Similarly, the vibration screen spring 3 is an existing well-known product and can be purchased directly from the market. Specifically, its structure can be a main spring, with rubber connecting seats at both ends of the spring, and the rubber connecting seats at both ends are used to respectively achieve soft connection with the screen 2 and the warehouse body 1. A frame connector 4 may be extended on the bin body 1 , and a soft connection between the vibrating screen spring 3 and the bin body 1 is achieved through the connection between the connecting seat and the frame connector 4 .

[0023] That is, the screen 2 of the material bin of the embodiment 1 is connected to the bin body 1 through the vibrating screen spring 3, and is connected through the spring seat of the vibrating screen spring 3. When the screen 2 needs to be replaced, the screen 2 can be directly replaced as a whole.

[0024] Example 2

[0025] Based on the material bin of the above embodiment 1, if the screen 2 needs to be conveniently replaced, the screen 2 can be set into two parts, that is, a screen support frame 5 fixedly connected to the bin body 1 through a vibrating screen spring 3, a screen body 6 arranged on the screen support frame 5 and tensionedly connected through a quick buckle 7, and one end of the buckle 7 is arranged on the screen body 5, and the other end is fixedly arranged on the screen support frame 6, such as Figure 2 and Figure 3 As shown. The side of the screen body 5 extends downward to be provided with a limit end, and a limit groove is provided on the screen support frame 6 corresponding to the limit end. For example, one end of the buckle 7 can be set on one side of the screen body 5, and the other three sides of the screen body 5 can be extended to be provided with a limit end, and the screen support frame 6 can be provided with corresponding limit grooves for the three sides, and then the screen body 5 is tensioned and fixed through the cooperation of the limit end, the limit groove and the quick buckle 7, so that under the action of the vibrator 10, the screen can be vibrated and prevented from slipping.

[0026] In addition to the above-mentioned Embodiment 1 and Embodiment 2, the material bin of the present invention further includes a support frame 9 for supporting the bin body 1, thereby improving its stability.
