Further, the feed port 121 extends from an edge of a free end of the take-out pipe 12 (e.g., a left end of the take-out pipe 12 shown in fig. 9) in an axial direction of the take-out pipe 12 (e.g., a left-right direction shown in fig. 9), and for example, the feed port 121 extends from an edge of a free end of the take-out pipe 12 in the axial direction of the take-out pipe 12 to an end adjacent to the take-out pipe 12 opposite to the free end (e.g., a right end of the take-out pipe 12 shown in fig. 9). From this, can guarantee that feed inlet 121 gets the homogeneity of material in material conveying pipe arrives, prevent to get the material inhomogeneous in the local material of getting in material conveying pipeline 800.

Further, the length of the inlet opening 121 of the take off pipe 12 is substantially equal to the inner diameter of the material delivery conduit 800. From this, when extracting pipe 12 stretches into material conveying pipeline 800, it can evenly get the material in material conveying pipeline 800's radial direction to get material pipe 12 to the even shape of assurance material of getting.
In some examples, referring to fig. 1, the extractor 1 extends obliquely downwards in a direction from the material conveying pipe 800 towards the splitter 2. That is, in the direction from the inlet end of the dispenser 1 to the outlet end of the dispenser 1, the dispenser 1 extends obliquely downwards. For example, the axis of the dispenser chamber 11 extends obliquely downwards in the left-to-right direction. Therefore, the material can be guaranteed to slide in the material taking device 1 by means of self gravity after being taken out from the material conveying pipeline 800.
Further, with reference to fig. 1, the central axis of the dispenser chamber 11 is at an angle in the range of 30 ° to 40 ° to the horizontal. Therefore, the material can be further ensured to slide in the material taking device 1 by means of the self gravity after being taken out from the material conveying pipeline 800.
