Meanwhile, the rock breaking bomb is short in on-site mounting time and convenient and simple to operate, and therefore operation efficiency for rock breaking of the crumbly rock can be greatly improved.
Description
Technical field
The present invention relates to the broken rock bullet of a kind of quick addi-tional crusher and cleaning rock mass, be specially adapted to the exploitation to soft astable rock mass in the underworkings.
Background technology
In underworkings excavation operation process, often there is the broken and cleaning to soft rock mass.At present, the conventional recovery method that generally adopts mainly contains drill eye blasting, development machine driving and artificial pneumatic pick and excavates three kinds of methods.From the exploitation principle, more than three kinds of methods all need the staff for a long time, closely near the soft rock mass operation, but have characteristics such as easy fragmentation, easy glide inbreak for soft astable rock mass, so bring great potential safety hazard can in the work progress related work personnel and heading equipment.On the other hand, excavating for drill eye blasting and artificial pneumatic pick also needs the staff to spend the plenty of time to utilize professional experiences to choose the appropriate location to carry out artificial jewel hole, thereby has the lower defective of production efficiency simultaneously.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of broken rock bullet that is applicable to the quick addi-tional crusher of downhole safety and cleaning soft rock mass is provided.
Technical scheme provided by the invention is: a kind of broken rock bullet for auxiliary cleaning underworkings soft rock mass, it is characterized in that: comprise brokenly rock bullet body and be used for the launching tube of the described broken rock bullet body of emission, launching tube is divided into emission inner core and emission urceolus, the emission urceolus is the interior tube length of emission, be cylindric, the two wherein an end interconnect by safety pin, and be fixed in simultaneously on the positioning base of ground; The other end of emission urceolus has opening, and the outside also is provided with the long distance wireless information transceiver, is provided with propulsive power source in the emission inner core, and its top is provided with discoid emission push pedal; Described broken rock bullet body comprises brokenly the rock body, two parts before and after its inside is divided into, and its anterior main charge of placing, balance weight body and fuse are equipped with in the rear portion, and its outer back end fixedly has rear-fin stabilizer, and its span is less than the internal diameter of emission urceolus; Broken rock bullet body places in the emission urceolus, and there is an end of opening its front portion towards launching urceolus, and its rear-fin stabilizer contacts with the emission push pedal.
As a kind of optimal way, described broken rock body adopts lightweight metal material to make, and this housing front portion is cylindric, and anterior top is set to the indent taper, and the rear portion is the evagination Gothic arch.
As a kind of optimal way, described balance weight body adopts the bigger inert material of density, places brokenly the rear portion of rock body.
As a kind of optimal way, the chord length of described rear-fin stabilizer accounts for brokenly more than 50% of rock bullet body overall length.
The present invention adopts the broken rock bullet realization of Remote emission to the fragmentation of soft rock mass, thereby effectively eliminated the on-the-spot potential safety hazard of bringing to staff and equipment when closely constructing, it is short to break rock bullet field installation time simultaneously, easy and simple to handle, therefore can improve the broken rock operating efficiency to soft rock mass greatly.
