Embodiment
Just preferred embodiment of the present utility model is described in detail with reference to accompanying drawing below, so that the advantages of utility model
It can be easier to be readily appreciated by one skilled in the art with feature, but embodiment not limited to this of the present utility model.
Before describing an embodiment, it is necessary to illustrate down, this means for loading is only applicable to existing emulsion, in reality
, from the powder stick of different-diameter, it can also be changed in operation according to the powder stick of different-diameter and filled according to the difference of blasthole diameter
Medicine device internal diameter, and then bursting work, and the present embodiment illustrates by taking the powder sticks of Φ 50, the blastholes of Φ 80 as an example, device design rule
Lattice are single branch powder stick, described in detail below：
Embodiment one：As shown in Figure 1, Figure 2 with shown in Fig. 5, a kind of simple blast hole projectile filling device, including powder charge pipe 1 and with the dress
Pencil 1 is integrally formed to block pipe 2, the tubular structure that the powder charge pipe 1 is surrounded by three arc-shaped flexure strips 3, the blocking
The outer wall of the hollow circular cylinder that pipe 2 is made using hard PVC, powder charge pipe 1 and blocking pipe 2 upper end is evenly arranged with back taper projection
10, the direction of the back taper projection 10 is diagonally downward.
Supporting table 4 is set for gap length according to the length of powder stick on the inwall of every flexure strip 3, the supporting table 4 is erected
Section is right angled triangle, and its upper surface is vertical with the inwall of flexure strip 3, and the blocking pipe 2 passes through with the cavity of powder charge pipe 1 isolates
Plate 5 separates, and blocks outer wall of the pipe 2 close to lower end and is connected with two support meanss 6 along the radial direction of pipe 2 is blocked, blocks the lower end of pipe 2
Pipe cap 7 is installed, the blind end center of the pipe cap 7 offers through hole 8, and the center of division board 5 offers through hole 11,
In the lower surface conducting wire pipe 9 of division board 5, the one end of conduit 9 connects with through hole 11, and the other end stretches out after passing through through hole 8
Blasthole.
Wherein, the support meanss 6 include set casing 61, spring 62 and support bar 63, and the set casing 61 is fixed on stifled
The outer wall of pipe 2 is filled in, the spring 62 is fixed in set casing 61, and described one end of support bar 63 is by spring 62 with blocking outside pipe 2
Wall connects, and the other end is circular arc and is close to blasthole inwall.
The length of the powder charge pipe 1 is more than the length for blocking pipe 2, and the diameter of the powder charge pipe 1 is consistent with blocking pipe 2.
Embodiment two：As shown in Figure 3 and Figure 4, in the case of other structures and the identical of embodiment one, as deformation, institute
It is gear to state support meanss 6, six is evenly arranged with top circle week sawtooth 64 is made using elastomeric material, sawtooth 64 uses
Hard PVC, the material bending fatigue resistance protrude, and avoid during drug delivery that sawtooth card is disconnected or gross distortion loses mechanical shape
Body.
When powder stick is sent into blasthole, because the outside diameter of gear is more than blasthole diameter, uphill process middle gear sawtooth is by blasthole wall
Extruding is in downward trend；Be sent into after blasthole makes sawtooth deform using explosive self gravitation, if charge weight control is certain
In the range of can then utilize sawtooth and hole wall stress be fixed in blasthole.
Utility model works principle：
Sawtooth and back taper projection 10 are that sawtooth and back taper projection 10 occurs using explosive and means for loading self gravitation
Deformation, make it with hole wall stress and be fixed in blasthole.
After powder stick and blocking consolidates under external force, external force gradually passes to flexure strip 3, makes it to big gun hole wall deformation,
Finally it is close to hole wall and forms larger frictional force, so as to undertakes a part of powder stick gravity.
Support meanss 6, back taper projection 10 and the gravity of the shared means for loading of flexure strip 3 and powder stick, make means for loading
It is fixed in blasthole.
