Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention
It is clearly and completely described it is clear that described embodiment is only present invention part reality
Apply example, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under the premise of not making creative work, broadly falls into this
The scope of invention protection.
Fig. 1 is the flow process of one embodiment of control method of oscillating feeder delivery rate of the present invention
Figure.As shown in figure 1, the control method of the oscillating feeder delivery rate of this embodiment offer, bag
Include：
Step 101, oscillating feeder feeds material to reaction type with certain delivery rate and crushes
Machine；Wherein, delivery rate one timing, raw meal particle size is bigger, and be connected with impact breaker is sent out
The load of motivation is bigger and rotating speed of engine is less；
Step 102, tachogenerator is according to predetermined period monitoring or real-time monitoring impact breaker
Present engine rotating speed during work, and send it to programmable logic controller (PLC) PLC；
Step 103, PLC controls oscillating feeder feed according to the present engine rotating speed receiving
Speed.
Specifically, in actual applications, the raw meal particle size of oscillating feeder supply is not necessarily uniform,
When raw meal particle size is excessive, the engine loading being connected with impact breaker also can increase, when send out
During motivation load excessive, the rotating speed of engine can reduce；When raw meal particle size is too small, with reaction type
Disintegrating machine connect engine loading also can reduce, when engine loading is too small, engine turn
Speed can increase.Tachogenerator can be according to predetermined period monitoring or real-time monitoring impact breaker
Present engine rotating speed during work, and it is sent to PLC.It should be understood that above-mentioned predetermined period is permissible
To set according to the actual requirements, exemplarily, this predetermined period can be set as especially little value,
With the effect reaching or near real-time is monitored.As an example, above-mentioned tachogenerator can be to use machine
Tool, electrically, the tachogenerator that manufactures of magnetic, light and the method such as hybrid, can be for example simulation
Formula or Digital Speed Testing sensor, however, the present invention is not limited to this.PLC can be according to reception
To present engine rotating speed to control the delivery rate of oscillating feeder.For example, bear in engine
When carrying excessive, that is, present engine rotating speed reduce when, PLC can correspondingly control oscillating feeder to
Material speed reduces, and to avoid excessive material to enter impact breaker, causes impact breaker
Blocking；Similarly, when engine loading is too small, when that is, present engine rotating speed increases,
PLC can correspondingly control oscillating feeder delivery rate to increase, with improve production efficiency.
The control method of the oscillating feeder delivery rate that the present embodiment provides, oscillating feeder is with one
Fixed delivery rate feeds material to impact breaker, wherein, delivery rate one timing, thing
Material is bigger, the load of the engine being connected with impact breaker is bigger and the rotating speed of engine more
Little；During using tachogenerator according to predetermined period monitoring or the work of real-time monitoring impact breaker
Present engine rotating speed, and send it to PLC；PLC is according to the current power receiving
Machine rotating speed controls oscillating feeder delivery rate.Compared with prior art, the present embodiment can basis

To control proportion magnetic valve mouth to reduce, thus reducing the oil mass by valve port, to reduce hydraulic motor
Rotating speed, and then reduce oscillating feeder delivery rate；It is more than default sending out in present engine rotating speed
During motivation rotating speed, PLC can control proportion magnetic valve mouth to increase, thus increasing the oil by valve port
Amount, to increase the rotating speed of hydraulic motor, and then increases oscillating feeder delivery rate.It should be appreciated that
Electromagnetism valve port increases or the amplitude of reduction can be preset value or empirical value.Correspondingly, in this enforcement
In example, if present engine rotating speed is equal to default engine speed, now, PLC does not need to adjust
The size of proportion magnetic valve mouth.
Further, as one of control method of the present invention above-mentioned oscillating feeder delivery rate
Specific example and unrestricted, above-mentioned PLC controls proportion magnetic valve mouth to reduce specifically can to include：
If present engine rotating speed is less than 0 with the difference of default engine speed, and not in preset range
Interior, then PLC controls proportion magnetic valve mouth to reduce.Correspondingly, above-mentioned PLC controls ratio electromagnetism
Valve port increase specifically can include：If present engine rotating speed is big with the difference of default engine speed
In 0, and not in preset range, then PLC controls proportion magnetic valve mouth to increase.Similar with upper
Ground, if the difference of present engine rotating speed and default engine speed is in preset range, now,
PLC does not need to adjust the size of proportion magnetic valve mouth.
Above-mentioned preset range can be configured according to the actual requirements, for example, it is desirable to turn to engine
When the control accuracy of speed is higher, then preset range can be set to smaller value；Otherwise,
Preset range can be set to than larger value.PLC pass through control proportion magnetic valve mouth increase or
Reduce, correspondingly control the rotating speed of hydraulic motor to increase or reduce, to increase or to reduce vibrating feed
Machine delivery rate, until the present engine rotating speed that tachogenerator monitors is turned with default engine
When the difference of speed is in preset range, stop adjustment oscillating feeder delivery rate.Otherwise, continue
