Figure 1 、 Figure 2 as well as Figure 5 As shown, it includes a screw conveyor 1, a buffer bin 2 is fixed on the surface of the screw conveyor 1, and the buffer bin 2 is communicated with the interior of the screw conveyor 1; the top sealing cover of the buffer bin 2 is closed with a bin cover 3, and the surface of the bin cover 3 is fixed with an exhaust pipe 4, and the exhaust pipe 4 is communicated with the interior of the buffer bin 2; a cleaning mechanism 5 is provided inside the buffer bin 2, and the cleaning mechanism 5 is used for cleaning the inner wall of the buffer bin 2, and the cleaning mechanism 5 includes an annular dovetail groove 51, a dovetail slider 52 and a brush 53, the annular dovetail groove 51 is opened on the inner wall of the top of the buffer bin 2, the inside of the annular dovetail groove 51 is slidably connected to the dovetail slider 52, and the bottom of the dovetail slider 52 is fixed with a brush 53, and the brush 53 is used for cleaning the powder attached to the inner wall of the buffer bin 2.

[0022] During implementation, the powder attached to the inner wall of the buffer bin 2 can be cleaned by manually pushing the brush 53 to rotate it around the annular dovetail groove 51 under the action of the dovetail slider 52 and the annular dovetail groove 51, thereby improving the convenience of cleaning the powder attached to the inner wall of the buffer bin 2.

[0023] Furthermore, if Figure 2 、 Figure 3 as well as Figure 4 As shown, the top of the exhaust pipe 4 is connected to a metering mechanism 6, which is used for controlling the amount of discharge. The metering mechanism 6 is composed of a momentum plate 61, a dynamic filter mesh port 62, a quantitative plate 63 and a fixed filter mesh port 64. The momentum plate 61 is rotatably connected to the inside of the exhaust pipe 4. A quantitative plate 63 is fixedly connected to the inside of the exhaust pipe 4 and is located below the momentum plate 61. The upper surface of the quantitative plate 63 and the lower surface of the momentum plate 61 are tightly attached to each other. Six groups of fixed filter mesh ports 64 are provided on the surface of the quantitative plate 63. Six groups of dynamic filter mesh ports 62 are provided on the surface of the momentum plate 61.
