It is easy to happen blocking.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of double-screw feeder, comprising: simultaneously
Arrange the first conduit, the second conduit of setting, the first helical blade in the first conduit, the second spiral shell in the second conduit
Vane piece；The directing plate being rotatably arranged on the interconnecting piece of first conduit and the second conduit, the directing plate and feed hopper
Position it is corresponding；It is described for monitoring for monitoring the first power monitor device of the first power of first helical blade
Second power monitor device of the second power of the second helical blade, with first power monitor device and the second power monitoring
The comparison unit of device connection, the driving device connecting with the comparison unit, the driving device are also connected with directing plate
It connects, so that: when the first power is differed with the numerical value of the second power reaches predetermined value, so that directing plate is to power higher one
Side channel road rotates predetermined angular.
Further, the comparison operation of progress in described comparison unit interval 1-10 minutes.
Further, it is connected with the first warning device in first power monitor device, when the first power is more than specified
Alarm signal is issued when value；It is connected with the second warning device in second power monitor device, when the second power is more than specified
Alarm signal is issued when value.
Further, the directing plate is rotatably arranged on the interconnecting piece by rotation axis, and the rotation axis passes through should
The shell of double-screw feeder, the driving device be arranged in the outside of shell and with rotation axis connection.
Further, the driving device includes motor and worm screw, and the worm gear engaged with worm screw is provided in rotation axis.
Further, the driving device includes stepper motor and gear, is provided with mate gear in rotation axis.
Due to the adoption of the above technical solution, after the utility model has the advantage that driving device completes adjustment, etc.
The material in the higher conduit of ingoing power is reduced, and the material in the lower conduit of ingoing power increases, favorably
In making material evenly distributing between two conduits, therefore the generation of the stopping state of feeding inlet can be effectively prevented from.
And whole process automation control, human input is not needed, is had the advantages that real-time, efficient.

Specific embodiment
The above objects, features, and advantages of the utility model in order to facilitate understanding, are illustrated below with reference to embodiment.It answers
Understand, these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.For these implementations
A variety of modifications of example will be apparent to those skilled in the art, the general principles defined herein,
It can be achieved in other embodiments without departing from the spirit or scope of the present utility model.
Referring to Fig. 1, a kind of double-screw feeder shown in Fig. 2, comprising: the first conduit 10 arranged side by side, the second conduit
20, the first helical blade 11 in the first conduit 10, the second helical blade 21 in the second conduit 20；Rotation setting
Directing plate 4 on the interconnecting piece 3 of first conduit 10 and the second conduit 20, the position pair of the directing plate 4 and feed hopper 5
It answers；For monitoring the first power monitor device 12 of the first power of first helical blade 11, for monitoring described second
Second power monitor device 22 of the second power of helical blade 21 is supervised with first power monitor device 12 and the second power
Control device 22 connect comparison unit 6, the driving device 7 being connect with the comparison unit 6, the driving device 7 also with guidance
Plate 4 is attached, so that: when the first power is differed with the numerical value of the second power reaches predetermined value, so that directing plate 4 is to function
The higher side conduit of rate rotates predetermined angular.
For example, the material in feed hopper 5 is mainly distributed on the right side in Fig. 1, after continuing for some time, lead to second
Material in conduit 20 is on the high side, therefore the second power of the second helical blade 21 is higher than the first function of the first helical blade 11
Rate.Comparison unit 6 is compared two magnitude of powers, when the numerical value of the second power is excessively high compared to the numerical value of the first power,
Illustrate that the material distribution in two conduits is quite uneven, needs to adjust in time.Then, driving device 7 issues instruction, so that guidance
Plate 4 rotates a predetermined angular to the second conduit 20.After driving device 7 completes adjustment, it is equal to so that into the second conduit
Material in 20 is reduced, and the material entered in the first conduit 10 increases, and it is equal between two conduits to advantageously allow material
Even distribution, therefore the generation of the stopping state of feeding inlet can be effectively prevented from.And whole process automation control, it does not need
Human input has the advantages that real-time, efficient.
In view of mechanical equipment adjustment need a process, therefore comparison unit 6 can be spaced one section of long period into
Comparison operation of row, such as 1-10 minutes.Otherwise the frequent movement that will cause driving device 7, it is dynamic even into endless loop
Make.
It is connected with the first warning device 13 in first power monitor device 12, is sent out when the first power overrate
It speaks, the alarm signals such as light；The second warning device 23 is connected in second power monitor device 22, when the second power is more than
The alarm signals such as sending sound, light when rated value.
The directing plate 4 is rotatably arranged on the interconnecting piece 3 by a rotation axis 41, and the rotation axis 41 passes through should
The shell 100 of double-screw feeder, the driving device 7 are arranged in the outside of shell 100 and connect with rotation axis 41.The driving
Device 7 may include motor and worm screw, corresponding, and the worm gear engaged with worm screw is provided in rotation axis 41, then, utilizes snail
Self-lock ability between worm and gear does not need to provide maintenance electric current to driving device 7.Also or, which includes stepping
Motor and gear, it is corresponding, mate gear is set in rotation axis 41, in the accurate corner control that can be achieved on rotation axis 41
System.It cuts both ways.
