Compared with all-hydraulic control of the prior art, the conveying control handle 1 in the present embodiment does not control directly defeated
Expect the aperture of control valve 3, but the input instruction of conveying control handle 1 received by controller 2, and according to the input instruction with
And default processing logic sends corresponding voltage or current controling signal to conveying control valve 3, to adjust in conveying control valve 3
The operating position of valve element, so as to realize the starting or stoping of conveying motor 4, forward or reverse and the slow-speed of revolution or high rotating speed etc..
The present embodiment is controlled using electrical control instead of section hydraulic, can be more compared to existing all-hydraulic conveying control process
Preferable control effect is realized under complicated construction operating mode.
As shown in Fig. 2 the structural representation of another embodiment for the utility model conveying control system.Implement with upper one
Example is compared, and the present embodiment also includes pressure sensor 5, and the pressure sensor 5 is used for the rotating forward work for detecting the conveying motor 4
Oil pressure, and it is supplied to the controller 2.Controller 2 is connected with the signal of pressure sensor 5, can be it is determined that the conveying
When the rotating forward operating oil pressure of motor 4 exceedes default putty pressure threshold, the conveying horse is controlled by the conveying control valve 3
Recover described up to 4 alternating rotatings, and when the rotating forward operating oil pressure of the conveying motor 4 is no more than the putty pressure threshold
The normal conveying process of conveying motor 4.
Rotating forward operating oil pressure has generally corresponded to conveying system more than default putty pressure threshold and the situation of putty has occurred, i.e.,
Because putty causes the load of conveying motor 4 to increase sharply so that the rotating forward operating oil pressure of conveying motor 4 is also improved therewith, when
During more than default putty pressure threshold, then it is assumed that putty situation it is more serious had influence on normal conveying process, it is necessary to enter
Row cleaning.Accordingly, putty pressure threshold is set after being then determined by historical data or many experiments.

Number, and the conveying motor 4 rotating forward operating oil pressure still above default putty pressure threshold when, notify manually block clearing
Or shut down the conveying motor 4 by the conveying control valve 3.
In the present embodiment, rotating control unit not only needs to control the positive and negative of conveying motor by conveying control valve
Turn, in addition it is also necessary to the number of times that the duration of control reversion, needs are inverted, when multiple reversion effectively can not carry out block clearing
Related personnel can be notified to carry out manual block clearing in time, according to circumstances shutdown processing can also can not be being carried out during block clearing, so as to
Related personnel is overhauled.
In the above-described embodiments, in addition to the rotating control of conveying motor, it can further include in controller 2
Start transition element, the unit is connected with the conveying control handle 1 and the equal signal of the conveying control valve 3, can be in system
The input current of the conveying control handle 1 is detected during startup increases to maximum current value under less than the default startup time
When, control is supplied to the current value of the conveying control valve 3 to be stepped up maximum current value with preset function.When conveying manipulation
The input current of handle 1 shows that operating personnel on startup will when increasing to maximum current value under less than the default startup time
Conveying control handle it is too fast shift maximum position onto, if according to existing all-hydraulic control mode, system shock can be caused,
And in the present embodiment by the startup transition element of controller to inputing to the control of the size of current of conveying control valve, can
Make the valve element of conveying control valve to move to the maximum position by flow step by step than shallower mode, will not thus make
Into system shock, it is ensured that the smooth starting of conveying motor.Here linear increasing function may be selected in preset function or parabola increases
Function.The parameter of wherein linear increasing function and parabola increasing function, which needs to meet, to be made to reach maximum current value from initial current value
Time is greater than the default startup time.
As shown in figure 3, the structural representation of the another embodiment for the utility model conveying control system.With above-mentioned each reality
Apply example to compare, human-computer interaction device 6 is also included in the present embodiment, the device is connected with the signal of controller 2, can show and be
Status information of uniting and fault alarm information, and putty pressure threshold can be carried out according to the outside input of reception, allows maximum anti-
Turn number of times, reversing time and/or the setting for starting the time.Human-computer interaction device 6 can be the touch-screen that can be inputted and show,
It can also be the combination of display and operation keyboard.In the interface example of human-computer interaction device for example shown in Fig. 4, keep left part
For conveying parameter setting interface, the interface can realize putty pressure threshold, allow maximum reversion number of times, reversing time and startup
The setting of time, and part of keeping right is conveying information display interface, the interface can show rotating forward oil pressure, reversion oil pressure, motor
