In practical operation, adjusting nut 824 in weighing device 80 is adjusted first, when lever 842 being made to be in steady state, peace
Base-material in the transition feed bin 70 on the first load receiving part 82 in the transition feed bin 70 being mounted on the second load receiving part 83
The weight ratio of auxiliary material meets the ratio between predetermined.Later, starting speed regulation delivery pump 20 and speed regulating motor 33, base-material and auxiliary material are defeated with adjusting the speed
It send the conveying of pump 20 and auger conveyor 30 to respectively fall in transition feed bin 70, after transition feed bin 70, passes through base-material discharge port
101 and auxiliary material discharge port 102 enter blending tank 10;The pulse generated by base-material pulse transmitter 52 and auxiliary material pulse transmitter 61
Electric signal transmission carries out operation to check weighing metering proportion controller 40, and operation result shows current base-material and auxiliary material weight respectively,
It shows percentage status of the current auxiliary material in base-material simultaneously, knows that proportion adjusts speed regulation delivery pump 20 and speed regulating motor 33 according to oneself
Revolving speed mix dosage with increase and decrease base-material or auxiliary material.Wherein, since the size and weight of two transition feed bins 70 itself are identical, because
This, the weight gain of transition feed bin 70 is to flow through the weight of the material of transition feed bin 70;When in a transition feed bin 70 base-material and
When the weight ratio actual coincidence of auxiliary material in another transition feed bin 70 is the ratio between predetermined, the lever 842 for receiving feedback section 84 begins
It is in steady state eventually;When in a transition feed bin 70 base-material and another transition feed bin 70 in auxiliary material weight ratio not
When meeting the ratio between predetermined, 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 axis 843, microswitch telescopic head 845 thereon is contacted with microswitch 846, and alarm device sounds, and prompts operator
Base-material accounting is excessive;If auxiliary material accounting is excessive, the guiding axis 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 alarm device sounds, and prompts operator's auxiliary material accounting excessive.Operator
Member can adjust speed regulating motor 33 according to the type of alarm device or adjust the speed the speed of service of delivery pump 20, until lever 842 is again
Reach steady (weight ratio of base-material and auxiliary material meets the ratio between predetermined), all clear.
Whether the weight ratio that above-mentioned weighing device 80 can directly detect base-material and auxiliary material in flow process meets
The ratio between make a reservation for, resulting base-material and auxiliary is measured and calculated by base-material pulse transmitter 82 and auxiliary material pulse transmitter 61 to make up
The error of the weight ratio of material.
When base-material and auxiliary material the ratio between predetermined changes, staff need to readjust the first load receiving part 82 and second
The elastic device 820 of load receiving part 83, adjustment process are as follows: staff's rotary worm 8590, worm drive worm gear 859 rotate,
Worm gear drives shaft 857 to rotate, and turns the rotation of shaft driven gear 858, and gear drives the first rack gear 851 and 854 straight line of third rack gear
Mobile, the moving direction of the first rack gear and third rack gear is opposite;Wherein, first the second rack gear of rack drives 852 moves together, the
The 4th rack gear 855 of three rack drives moves together;First rack gear passes through the ring gear 8240 engaged and drives in the first load receiving part
Row's adjusting nut 824 rotation, what the second rack gear passed through that the ring gear that engages drives in the first load receiving part another teases and ridicule section
Nut rotation, similarly, row's adjusting nut rotation in the second load receiving part of third rack drives 83, the 4th rack drives second are held
Another row's adjusting nut rotation in weight portion;Since the first rack gear and the second rack gear move simultaneously, the first load receiving part is held
Weight plate 827 can be gone up and down under the premise of holding level, and similarly, the bearing plate of the second load receiving part can also be under the premise of keeping horizontal
Lifting;Due to the moving direction of the first rack gear and third rack gear on the contrary, therefore, when the bearing plate of the first load receiving part rises, second
The bearing plate of load receiving part declines, and when the bearing plate of the first load receiving part declines, the bearing plate of the second load receiving part rises.
Wherein, the workflow of transition feed bin 70 is as follows: base-material falls into the charging of transition feed bin 70 on the first load receiving part 82
Mouth 701, at this point, pushing disc 74 is located at the right side of feed inlet;Under the drive of the motor, threaded rod 75 rotates, and driving is promoted and faced left
It moves, while driving the first rotating vane group 77 and the rotation of the second rotating vane group 78, in this way, the base-material into transition feed bin is pushed away
Push the first rotating vane group into disk;Since the outer diameter of pushing disc is equal to the internal diameter of middle part inner cavity, the pushing disc moved to left will
The air pressure of the left side cavity of 71 inner cavity of middle part is compressed and increases the air pressure of left chamber body, and then makes left chamber's gas of left part 72
Pressure increases, this not only contributes to the first rotating vane group 77 and base-material is broken up and stirred, moreover, being conducive to base-material rapidly
It is sprayed into blending tank 10 downwards through the first tapping channel 720;When pushing disc is moved to left to 72 left chamber body of left part, motor reversal,
Driving pushing disc 74 moves to right, at this point, the base-material for constantly entering transition feed bin through feed inlet has been filled with the middle part on the right side of pushing disc
The right side cavity of 71 inner cavities, the pushing disc moved to right push base-material to second rotating vane group, make the right chamber air pressure liter of right part 73
Height, base-material rapidly spray into blending tank downwards through the second tapping channel;With pushing disc moving left and right repeatedly, base-material is continuous
Ground sprays into blending tank from first material outlet 720 and second material outlet 730.With the transition feed bin 70 on the first load receiving part 82
Similarly, the pushing disc or so in the transition feed bin on the second load receiving part 83 moves repeatedly, by auxiliary material constantly from the second load receiving part
On transition feed bin first material outlet and second material outlet spray into blending tank in.
