Accompanying drawing explanation
Fig. 1 schematic illustration vortex crushing machine.
Fig. 2 is exemplified with breaker.
Fig. 3 shows the flow chart of method.
The specific embodiment
Fig. 1 is exemplified with vortex crushing machine 1.This disintegrating machine 1 comprises that bias is arranged on the roughly vertical crusher shaft 3 on its lower end 5.Be in operation, crusher shaft 3 will be carried out synchronous rotary and oscillating motion.Crusher shaft 3 is in the top with broken head 7, and the outer surface of this fragmentation head 7 is provided with the inner casing 9 consisting of hard material.
With the shell 11 shown in section form, in following this mode, be arranged on (not shown) in frame, that is, shell 11 is around inner casing 9, thereby forms ring crush chamber 13 between inner casing and shell 9,11.As shown in the figure, the sectional area of crushing chamber 13 can reduce towards its underpart.Minimum clearance S between inner casing and shell 9,11 is located at the bottom of crushing chamber 13, and due to synchronous rotary and the oscillating motion of crusher shaft 3, this gap S changes the periphery of the bottom around inner casing 9 continuously.
At run duration, the raw material that are generally the rock material of explosion are supplied to crushing chamber 13 at the place, top of crushing chamber 13, and due to the relative motion between inner casing 9 and shell 11, raw material are broken between these parts.The size of the minimum clearance S of crushing chamber 13 has determined the crushing function that will carry out, for example, determined that the particle diameter of the crushing material produced distributes and shape.In order to make minimum clearance S adjustable, can carry out vertically mobile crushing arbor 3 by means of the adjusting device 15 that is generally hydraulic cylinder.
Fig. 2 schematic illustration there is the disintegrating machine 1 of driver element 17 and control module 19.Driver element 17 comprises the Diesel engine 18 that drives crusher shaft 3 by connection unit (not shown).Use Diesel engine 18 to make disintegrating machine 1 be suitable for portable structure, this is because do not need to be connected with electrical network.Therefore, breaker can move to another place from the three unities, and therefore can be for example for road construction, so that the rock of explosion is made to gravel.Can control this Diesel engine by means of the control loop 21 separating, so that it turns round under the predetermined expectation rotating speed of for example 1800rpm.
Control module 19 carrys out the adjusting device 15 of controlled fragmentation machine 1 according to different control parameters, that is, crusher shaft 3 is moved up or down.The input from the input unit 23 such as keyboard of 19 pairs of control modules responds, and makes user for example can calibrate this disintegrating machine and set different operational factors.If adjusting device 15 is hydraulic cylinders, control module 19 can be controlled by control circuit 25 its hydraulic coupling.Also can in this hydraulic cylinder, arrange pressure sensor 27, this sensor generates pressure signal, and this pressure signal is fed to this control module by feedback line 29.In addition, this breaker can have position sensor 31, and this position sensor 31 is measured the position of axle 3 and therefore indirectly measured the minimum clearance S of crushing chamber, and corresponding sensor signal is fed to control module 19 by sensor line 33.As original known, therefore control module 19 can be controlled to desired value by hydraulic coupling and/or gap S.Axle between driver element 17 and disintegrating machine 1 can be provided with the fluid coupling 28 that soft start function is provided for described breaker.The output shaft of this fluid coupling for example can be provided with inductance type transducer, to be used for measuring rotating speed.
If be fed to, the material of the imposed load in the crushing chamber 13 of disintegrating machine 1 is too hard or density is too large, if or too many material is fed to disintegrating machine 1, the Diesel engine 18 of driver element 17 may stop working.If this thing happens,, before Diesel engine 18 can be reset, must first raw material be removed from disintegrating machine, this is one and bothers and time-consuming work.
Therefore, use sense line 30 to obtain load parameter value from this Diesel engine.The load of this value and engine is relevant and can use known J1939 interface to obtain.This load parameter value can be derived from turbo boost pressure corresponding with the percentage of maximum load, that is, be 0%-100%.
Control module 19 comprises comparator 32, this comparator 32 for example 80% compares obtained load parameter value and predetermined overloading threshold, if surpassed this predetermined overloading threshold,, conventionally by reducing the hydraulic coupling of adjusting device/hydraulic cylinder 15, the limiter 34 in control device 19 increases the minimum clearance S of crushing chamber 13.Increase minimum clearance S has alleviated the fragmentation of being undertaken by this disintegrating machine and has worked, and therefore causes the load fast reducing on Diesel engine 18.Thus, can avoid the overload of this Diesel engine and stop working.
Much less, most of functional module of control module 19 can realize by software.Yet, also can expect the parts of control module 19 to be embodied as special hardware, for example use ASIC.
Therefore, main inner control loop can be set, this inner control loop is measured the hydraulic coupling of minimum clearance S and/or hydraulic cylinder, and any in these parameters is controlled to desired value.In addition, auxiliary external circuit is also set, the load of Diesel engine is measured in this external circuit, and, if surpass load threshold value, by increasing minimum clearance S, affect home loop.Conventionally, external circuit can reduce the minimum clearance value set point of home loop.
In addition, if surpass threshold value, control module 19 can give the alarm by the sense of hearing and/or sighting device, and this sense of hearing and/or sighting device be loudspeaker 35 and/or lamp 37 normally.Alternately, before surpassing overloading threshold, can be by obtained load parameter and the lower mode that warning threshold compares and execution is warned when surpassing this warning threshold be given the alarm.
Fig. 3 shows the flow chart of method.From initial starting state 41, breaker enters running status 43, this running status 43 times, by broken raw material in disintegrating machine, these raw material is made to gravel.Under this running status, from Diesel engine, obtain load parameter value 45 and compare 47 with threshold value simultaneously.If surpass threshold value, show to occur overload conditions, optionally generate alarm 49, for example, described above by the mode that lamp is flashed, and minimum clearance S is increased to 51, thus can avoid the flame-out of Diesel engine.Subsequently, in the given time, this breaker keeps under this operational mode and repeats this measuring process.Therefore, can further reduce minimum clearance.If comparison step 47 show that load parameter value is lower than threshold value, can just continue the operation of this breaker.If minimum clearance has increased and do not occur in the given time new overload conditions, minimum clearance optionally in a step-wise fashion can be subtracted back to normal value.
A kind of method of breaker and this breaker of control has been described in a word.This breaker comprises vortex crushing machine, and these vortex crushing facility are useful on the device of the minimum spacing in controlled fragmentation chamber and by diesel engine drives.For example by J1939 interface, from Diesel engine, obtain load value.If the value of obtaining has surpassed predetermined threshold value, increase minimum spacing.Therefore diesel motor flameout can be avoided, thereby the continuous operation of this breaker can be guaranteed.
The invention is not restricted to described embodiment, but can change within the scope of the appended claims.For example, can expect other adjusting device except hydraulic cylinder.The disintegrating machine 1 of above having described has the broken head in the crusher shaft of being fixed to.According to alternate embodiment, as described in WO2006/067277, this fragmentation head can slide along fixed axis by means of hydraulic cylinder.
It is also understood that except above-mentioned vortex crushing machine, the present invention also can be applicable to the disintegrating machine of other type of vertical position that can this inner casing of hydraulic regulation.In other cases, the present invention also can be applicable to mechanically set in the disintegrating machine in the gap between inner casing and shell, for example, in US Patent No. 1,894, and the disintegrating machine of the Symons type by name of describing in 601.In the disintegrating machine that is called once in a while Symons type of mentioning, carry out in the following manner the setting in the gap between inner casing and shell in the above: wherein, shell is fastened, be threaded in frame and with respect to this frame and rotate, to realize the gap of expectation.In the modification of this type of disintegrating machine, utilize a plurality of hydraulic cylinders to replace screw thread to carry out the adjusting in the fastened situation of shell.The present invention is also applicable to such disintegrating machine.
