Further, as shown in fig. 1, a distance between the detecting unit 3 and the feeding end 11 along the first direction is a first distance, a distance between the detecting unit 3 and the discharging end 12 along the first direction is a second distance, and the first distance is smaller than the second distance. The position of the detection unit 3 is close to the feeding end 11, so that the height of the tobacco can be identified in time when the tobacco just enters the conveying channel 1; and set up detecting element 3 among the prior art and detect the tobacco material height at discharge end 12, if the tobacco material blocks up in transfer passage 1 middle section, then detecting element 3 can't detect the jam condition, can not solve the jam problem even more.

Further, the ratio of the first distance to the second distance is 0.1-0.5. In practical applications, if the tobacco material is loose and has a low probability of agglomeration and clogging, the ratio of the first interval to the second interval may be set to 0.5. If the tobacco material bulk is low, easy caking, can set the ratio of first interval and second interval to 0.1, make detecting element 3 be closer to pan feeding end 11, in time detect the height that gets into the tobacco material in conveying passage 1 to in time adjust conveying speed, make the tobacco material on the conveying mechanism 2 maintain at reasonable height.
