[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] The embodiment of the present application discloses an intermittent feeding structure of a color sorter, including a feed box 2, a storage hopper 3 is provided at one end of the feed box 2, a dividing box 5 is provided at the other end of the feed box 2, a uniform feeding mechanism is provided in the feed box 2, and is used to transport the raw materials in the storage hopper 3 to the dividing box 5, and a dividing mechanism is provided in the dividing box 5, and the dividing mechanism can divide the raw materials into equal parts and feed them into the color sorter.

[0018] Furthermore, a support frame 1 is fixedly connected to the bottom of the feed box 2, and the support frame 1 is installed on the surface of the color sorter by bolts, so that the discharge channel 6 is located at the entrance of the color sorter.

[0019] Furthermore, the storage hopper 3 is located above the feed box 2 , and the storage hopper 3 is connected to the feed box 2 .

[0020] Furthermore, the feeding mechanism includes a rotating shaft 8 rotatably installed in the feeding box 2, a screw blade 9 is fixedly connected to the rotating shaft 8, a first motor 4 is fixedly installed on the surface of the feeding box 2, and an output shaft of the first motor 4 is fixedly connected to the rotating shaft 8.

[0021] Furthermore, the material dividing mechanism includes a rotating rod 10 rotatably installed in the material dividing box 5, and a plurality of groups of material dividing plates 12 distributed in a ring array are fixedly connected to the surface of the rotating rod 10. The material dividing box 5 is arranged in a cylindrical shape, and the material dividing plates 12 are rotatably matched with the inner wall of the material dividing box 5. The material dividing plates 12 divide the material dividing box 5 into multiple groups of material spaces. A second motor 7 is fixedly connected to the bottom of the material dividing box 5, and the output shaft of the second motor 7 is fixedly connected to the rotating rod 10. A discharge port 11 is opened on the lower surface of the material dividing box 5, and a discharge channel 6 is fixedly connected to the discharge port 11.

[0022] In this embodiment, several groups of dividing plates 12 in the dividing mechanism divide the dividing box 5 into multiple dividing spaces. The second motor 7 drives the rotating rod 10 and the dividing plate 12 to rotate, thereby driving the dividing space to rotate, and the feeding mechanism transports the material to each dividing space in turn.

[0023] During feeding, by driving the first motor 4, the rotating shaft 8 and the auger blade 9 are driven to rotate. After the material in the storage hopper 3 falls into the inside of the feed box 2, it is evenly transported to one of the dividing spaces in the dividing box 5 through the auger blade 9. By driving the second motor 7, the rotating rod 10 and the dividing plate 12 are driven to rotate, which can drive the material in the dividing space to rotate. When the material rotates to the side of the discharge port 11, the material can be transported to the color sorter through the discharge port 11 and the discharge channel 6.

[0024] In actual use, by controlling the rotation speed of the first motor 4 and the second motor 7, the conveying speed and the material separation speed are controlled to achieve equal material conveying, so that the amount of material entering the color sorter is consistent, thereby ensuring the screening effect of the color sorter.
