[0027] The inclined chute pipeline 1 includes an inclined pipeline 101 arranged downward in the middle, the upper end of the inclined pipeline 101 is connected to an upper vertical pipeline 102 and the lower end is connected to a lower vertical pipeline 103; the ends of the upper vertical pipeline 102 and the lower vertical pipeline 103 are both provided with connecting flanges 14.

[0028] The connecting flange 14 is a square flange.

[0029] A plug plate 2 is plugged into the upper end of the top plate of the inclined pipe 101, and the plug plate 2 is vertically inserted into the inclined pipe 101. A material channel is left between the plug plate 2 and the bottom plate of the inclined pipe 101.

[0030] The viewing window is a flange opening, and the light of the near infrared analyzer 8 passes through the viewing window 7 to illuminate the material flowing through the pipeline.

[0031] There are several baffle plate assemblies 3 on the bottom plate of the inclined pipeline 101.
