Adjusting nut 12 carries out interim manual centering.
Specific working principle explanation is made to the present embodiment below.It is preferred that: the voltage DC24V of Linear motor-driven push rod 3 stretches
The impulse stroke of bar 4 is S (millimeter), and the transmission speed of grain conveyer belt 5 is V (mm/second), and the push/pull of telescopic rod 4 is
F (newton).Based on above-mentioned parameter, when telescopic rod 4 is calibrated, the identical extended and retracted stroke of preferably telescopic rod 4 is S/
2, at this point, the greatest limit working time of Linear motor-driven push rod 3 is T=S/2V.As shown in figure 4, the push/pull of telescopic rod 4
5 tensile force of grain conveyer belt should be enabled sufficiently large, without opposite sliding between grain conveyer belt 5 and live-roller 7；If: driving grain
The power of the motor of conveyer belt 5 is P, and efficiency η, the transmission speed of grain conveyer belt 5 is V, and grain conveyer belt 5 is with respect to live-roller
7 coefficient of friction is μ, and the normal pressure that grain conveyer belt 5 acts on live-roller 7 is N.It can be obtained according to above-mentioned parameter:
Function made by frictional force of the grain conveyer belt 5 with respect to live-roller 7 are as follows: W=N μ Vt is (when t is that grain conveyer belt 5 is run
Between), corresponding friction horsepower p '=N μ V can be obtained by P η=N μ V:
Normal pressure N=P η/μ V, so the push/pull F of telescopic rod 4 should meet:
F〉Pη/2μV。
The present embodiment has one section of longer time to prolong it is considered that from being adjusted to adjust to centering after the offset of grain conveyer belt 5
Late, belt overshoot phenomenon will occur for continuous adjustment, left and right reforming phenomena occur so as to cause grain conveyer belt 5, so necessary
First grain conveyer belt 5 is finely adjusted, then according to fine tuning effect, then determines to increase adjustment amount or reduces adjustment amount.Separately
Outside, adjustment has a limit, and the overhang or indent of the preferred telescopic rod 4 of the present embodiment are no more than the 1/ of the flexible throw of lever
2, i.e. maximal adjustment time is necessarily less than T=S/2V.When between when adjusted close to T, controller 2 can control telescopic rod 4 and stop fortune
It is dynamic, and alarm signal is issued, remind worker to come to overhaul.According to above-mentioned principle, if t is initial adjustment time, when τ is observation
Between.As shown in figure 5, the stroke S of telescopic rod 4, the stretching speed V of telescopic rod 4, scale factor p, observing time τ etc. are joined first
Number is input in controller 2, is preferably inputted by touch screen；Then program is adjusted by the centering algorithm being incorporated into controller 2
Limit adjustment time T is calculated, then initial adjustment time t=pT；Then controller 2 starts to scan laser in centering sensor 1
Tube-launched left and right offset signal.When controller 2 receives left avertence signal, controller 2 controls telescopic rod 4 according to speed
It spends V and stretches out the t time, after waiting the τ time, whether observation grain conveyer belt 5 is returned, if telescopic rod 4 no longer stretches out in returning,
The initial time that next time is adjusted remains as t；If in not returning, and grain conveyer belt 5 illustrates flexible also in left avertence shifting state
The stretching time of bar 4 is inadequate, is needed using t+pt as new initial time t ', when controlling telescopic rod 4 according to speed V stretching t ' at this time
Between, however if therefore grain conveyer belt 5 is biased to the right and goes again, illustrate that new initial time t ' value is excessive, also needs t-pt
It is used as initialization time t " again, control telescopic rod 4 is reversely retracted the time of t ", in this way, learning by oneself by above-mentioned a period of time
After habit, the value of initial time is just relatively suitble to operating condition, to complete the fine tuning to grain conveyer belt 5.This algorithm, for
Various various sizes of machines or driving wheel, belt abrasion, the big occasion of blanking shock vibration, can by it is above-mentioned from
Study, obtains the working time parameter of suitable telescopic rod.As shown in Figure 5, fine tuning journey when being scale factor p=1/2
Sequence process.
After fine tuning, system just enters the stage that real-time detection offset and real-time centering are adjusted.As shown in figure 3, working as grain
When conveyer belt 5 is deviated to the left side, the first reception pipe 1-4 receives the signal of first laser transmitting tube 1-2 transmitting, and to controller 2
Left offset signal is issued, controller 2 receives the calculating of progress offset after left avertence shifting signal, control Linear motor-driven push rod 3
The protruding corresponding length of telescopic rod 4, so that 7 lower end of live-roller as shown in Figure 1 moves to right, grain conveyer belt 5 will move right
It moves until returning to middle position；Similarly, when grain conveyer belt 5 is deviated to the right, the second reception pipe 1-5 receives second laser hair
The signal of pipe 1-3 transmitting is penetrated, and issues right offset signal to controller 2, controller 2 is deviated after receiving right avertence shifting signal
The telescopic rod 4 of the calculating of amount, control Linear motor-driven push rod 3 retracts corresponding length, so that 7 lower end of live-roller as shown in Figure 1
It moves to left, grain conveyer belt 5 will be moved to the left until returning to middle position.
It can be seen that the conveyer belt dynamic centralising device of the utility model, structure is simple, is examined by setting centering sensor
Survey conveyer belt whether centering, and the centering signal real-time transmission that will test is to controller, after calculating offset by controller
One end of offset adjustment actuating mechanism front and back adjustment live-roller is controlled, until the middle line at the midpoint of live-roller and grain conveyer belt
It is overlapped, so that the real-time automatic centering for realizing grain conveyer belt be forced to adjust, is not only convenient for maintenance positioning, and centering adjusts effect
Fruit is good, and runnability is reliable, is conducive to the stability and high efficiency transmission of grain, can have for the strength interference of various outsides
Effect is corrected, and is solved Grain Trade grain conveyer belt and is easy the drawbacks of breaking, practical.
Centering sensor can reliably detect conveyer belt offset in the biggish occasion of dust simultaneously；And U-shaped branch
The setting of buffer spring on the outside of the recess internal trolley and u-bracket of frame, can be in grain conveyer belt by disturbance is too big or component
Damage and when unidirectional deviate occurs, prevent sensor degradation or grain conveyer belt from isolating, be conducive to the stability for improving device and
Service life.
It should be noted that it is obvious to a person skilled in the art that the utility model is not limited to above-mentioned demonstration in fact
The details of example is applied, and without departing substantially from the spirit or essential attributes of the utility model, it can be with other specific shapes
Formula realizes the utility model.It therefore, in all respects, the embodiments should be taken as exemplary, and is non-limit
