Abstract

The utility model relates to a quick powder charge tamper, it includes medicated roll, it still includes push rod, outer tube, clamping screw, elastic stop block, compression spring, the outer tube tail end leaves there are two spacing windows, and outer tube head section is equipped with two fixed slot, the outer tube head duan ke medicated roll that packs into, the push rod head end is equipped with cuts somebody's hair, and the push rod rear is equipped with the elastic stop block that can open and close, spring pocket installs between two fixed slot on the push rod, and wherein compression spring has one end to withstand clamping screw, the push rod displacement of can making a round trip in the outer tube, elastic stop block opens the spacing window of card income outer tube tail end and stops when returning, cuts somebody's hair when going and releases medicated roll from outer tube head section. It have protection medicated roll intact, reduce advantages such as powder charge card hole phenomenon, fast, the accurate control medicated roll interval of powder charge, blasting safety nature are good, be suitable for the blasting construction applied.

Description

Quick-burning charge tamper

Technical field

The utility model relates to a kind of blast working charge loading tool, specifically a kind of quick-burning charge tamper, is suitable for blast working application.

Background technology

At present, the charging means of most of engineering explosion first powder stick is put into big gun hole, and then powder stick is pushed precalculated position by direct tamper, adopts common loading method to have following drawback: 1, powder stick is easily because blasthole hole wall is rough, cause powder stick damaged, affect demolition effect; 2, in propelling movement powder stick process, easily because of hole clipping, increase and push difficulty; 3, when underground borehole blasting, unfamiliar operating personnel can not accurately control powder stick spacing, easily causes powder charge not in place.

Therefore, research and develop a kind of quick-burning charge tamper and just seem there is certain realistic meaning.

Summary of the invention

The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of quick-burning charge tamper, it can available protecting powder stick complete, reduce powder charge and block, again can accurate controlled loading of explosive spacing, reduction labour intensity, thus realize quick powder charge.

For achieving the above object, the utility model adopts following technical scheme:

Quick-burning charge tamper, it comprises powder stick, and it also comprises push rod, outer tube, standing screw, flexible block, Compress Spring; Outer tube tail end has two spacing windows, and outer tube head section is provided with two fixed card slots, and outer tube head section can load powder stick; Push rod head end is provided with cuts somebody's hair, and push rod rear is provided with flexible block able to turn on or off; Compress Spring is enclosed within push rod, and be installed between two fixed card slots, wherein Compress Spring has one end to withstand standing screw; Push rod can displacement back and forth within the outer tube, and when returning, flexible block opens and snaps in the spacing window of outer tube tail end and stop, and cuts somebody's hair powder stick to release from outer tube head section when going.

Described outer tube outer wall is marked with scale, can accurately control powder stick spacing.

Advantage of the present utility model:

1. when powder charge, because powder stick does not directly contact with hole wall, therefore can available protecting powder stick complete, avoid powder stick damaged, affect demolition effect;

2. reduce powder charge hole clipping phenomenon, powder stick is pushed more smooth, powder charge speed is faster;

3. tamper outer tube is labeled with scale, when underground borehole blasting, can accurately control powder stick spacing, improves shotfiring safety.

Accompanying drawing explanation

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is a kind of quick-burning charge tamper perspective view according to the utility model proposes.

Fig. 2 is the push rod of tamper shown in Fig. 1 action perspective view.

Fig. 3 is the structural representation of the push rod of tamper shown in Fig. 1.

In figure, each mark represents respectively:

1. outer tube 2. spacing window 3. fixed card slot 4. push rod 5. standing screw 6. is cut somebody's hair 7. flexible block 8. Compress Spring 9. powder stick scales

Be described in further detail below in conjunction with accompanying drawing.

Detailed description of the invention

As shown in Figure 1, Figure 2, Figure 3 shows, quick-burning charge tamper, it comprises powder stick 9, and it also comprises push rod 4, outer tube 1, standing screw 5, flexible block 7, Compress Spring 8; Outer tube 1 tail end has two spacing windows 2, and outer tube 1 section is provided with two fixed card slots 3, and outer tube 1 section can load powder stick 9; Push rod 4 head end is provided with cuts somebody's hair 6, and push rod 4 rear is provided with flexible block 7 able to turn on or off; Compress Spring 8 is enclosed within push rod 4, and be installed between two fixed card slots 3, wherein Compress Spring 8 has one end to withstand standing screw 5; Push rod 4 can displacement back and forth in outer tube 1, and when returning, flexible block 7 opens and snaps in the spacing window 2 of outer tube 1 tail end and stop, and cuts somebody's hair 6 to be released from outer tube 1 section by powder stick 9 when going.

Described outer tube 1 outer wall is marked with scale, can accurately control powder stick spacing.

Described push rod 4 length is greater than outer tube 1 length.

During work, first powder stick is put into tamper head end, secondly tamper is pushed the precalculated position in big gun hole, again promote push rod 4 and powder stick is released outside tamper, finally press flexible block, push rod 4 automatic drawing back, a powder charge can be completed.

As mentioned above, just can realize the utility model preferably, other meet do under Spirit Essence of the present utility model and principle modification, increase and decrease, substitute, combination all should be equivalence substitute mode, be included in protection domain of the present utility model.
