When meeting predetermined ratio, 842 run-off the straight of lever;If base-material accounting is excessive, positioned at leading for the transition feed bin side 70 for containing base-material
Rise to axle 843, microswitch telescopic head 845 thereon is contacted with microswitch 846, and siren sounds, point out operating personnel
Base-material accounting is excessive;If auxiliary material accounting is excessive, the axis of guide 843 positioned at 70 side of transition feed bin for containing auxiliary material rises, thereon
Microswitch telescopic head 845 is contacted with microswitch 846, and siren sounds, and points out operating personnel's auxiliary material accounting excessive.Operator
Member can be according to the species of siren to adjust the speed of service of buncher 33 or speed governing delivery pump 20, until lever 842 is again
Reach steady (weight ratio of base-material and auxiliary material meets predetermined ratio), all clear.
Above-mentioned weighing device 80 can the weight ratio of base-material and auxiliary material of the direct detection in the flow process whether meet
Predetermined ratio, is measured as base-material pulse transmitter 52 and auxiliary material pulse transmitter 61 and base-material obtained by calculating and auxiliary with making up
The error of the weight ratio of material.
Above content is only the better embodiment of the present invention, for one of ordinary skill in the art, according to the present invention
Thought, will change in specific embodiments and applications, this specification content is should not be construed as to this
Bright restriction.
