For a full-automatic crushing system for oversized fragment, comprise range-measurement system 3, control system 2 and breaker 1, wherein, described breaker comprises broken bore bit 4, telescopic arm 5 and fixed station 8; Described telescopic arm to be installed on described fixed station and to drive bore bit to move in three dimensions;
Described range-measurement system is installed on telescopic arm 5 front end of breaker, and the distance measuring signal controlled fragmentation device that described control system is fed back based on range-measurement system implements fragmentation procedure.
The signal transmission direction of described range-measurement system is vertical with on level ground.
Described range-measurement system comprises LDMS and ultrasonic ranging system.
By Landline communication unit or wireless communication unit communication between described control system and breaker.
A kind of automatic-explosion method, the full-automatic crushing system for oversized fragment described in employing, comprises following step:
Step 1: the transmitter of setting range-measurement system is to the distance fixed value H0 every plug between level ground;
Step 2: control system sends control instruction, starts range-measurement system;
Step 3: when record be less than H0 from transmitter to the distance H of sillar 12 every plug 13 time, enter step 4, otherwise, enter step 5;
Step 4: control system sends control instruction by central data processor, makes telescopic arm 5 move down, and broken bore bit 4 starts brokenly rock, until the distance between sillar and range-measurement system 3 is greater than fixed value H0;
Step 5: control system 2 controls telescopic arm and moves to next scanning position, returns step 2 and processes next target object, until complete predetermined broken task.
Beneficial effect
The invention provides a kind of full-automatic crushing system for oversized fragment and automatic-explosion method, this full-automatic crushing system comprises range-measurement system 3, control system 2 and breaker 1, wherein, described breaker comprises broken bore bit 4, telescopic arm 5 and fixed station 8; Described telescopic arm to be installed on described fixed station and to drive bore bit to move in three dimensions; Described range-measurement system is installed on telescopic arm 5 front end of breaker, and the distance measuring signal controlled fragmentation device that described control system is fed back based on range-measurement system implements fragmentation procedure.In the development course of crushing system, do not occur automatic crushing device always, need a large amount of manpower and materials, range-measurement system applies in crushing system by the present invention cleverly, makes whole crushing system achieve unmanned control; Whole crushing system structure is simple, is easy to control, and substantially increases operating efficiency; Based on the automatic-explosion method of this crushing system, broken accurately by realizing the judgement of distance measuring signal, improve broken accuracy greatly; Based on control system, the distance fixed value H0 every plug between the transmitter of range-measurement system to level ground is changed, the fragmentation between any distance can be realized, make this crushing system and method can be adapted to carry out fragmentation in multiple environment.
