Abstract
The invention discloses a charging device for blast holes of different diameters. The device comprises a hopper used for charging; a step is arranged in the middle of the hopper; four grooves are evenly formed in the periphery of a lower end opening of the hopper; a pin shaft is installed at one end of each groove; rotary blocks are installed inside the four grooves of the hopper through the pin shafts correspondingly; the grooves are formed in the positions, making contact with the rotary blocks, inside the hoppers; springs are installed at the bottoms of the rotary blocks; and the other ends of the springs are fixed to the grooves. By the adoption of the device, when a blast hole needs to be filled with explosives, the device is inserted into the blast hole, the rotary blocks inside the grooves of the hopper are extruded by the wall of the blast hole to compress the springs to rotate during insertion till the four rotary blocks are pressed into the blast hole and expand automatically with the blast hole, and then the device continues to be inserted till the step makes contact with the end face of the blast hole.
Description
Technical field
The present invention relates to a kind of blast hole projectile filling device that can be used for different pore size.
Background technology
Surface blasting construction is generally located at outside of the city, and due to the produced a large amount of rubbles of bursting work construction, building site is rubble not of uniform size on the ground everywhere; In the air bench blasting adopting relatively light shot aperture, accidental cause during due to construction, causes rubble to fall into big gun hole and the thing of plug-hole often occurs, form useless hole therefrom, affect blasting quality. Additionally, big gun hole for obstructed diameter, when carrying out charging, if using non-web-like porous particulated ammonium oil explosive, in order to avoid waste explosive, need the means for loading using different big gun hole instead could effectively be directed at big gun hole and topple over explosive, nonetheless, owing to error is also easy to waste explosive in big gun aperture, owing to blasthole diameter is more various, using instead during different pore size means for loading comparatively laborious during filling, labor intensity is bigger.
Summary of the invention
For the deficiencies in the prior art part, it is desirable to provide a kind of blast hole projectile filling device that can be used for different pore size, both went for gun muzzle powder charge in multiple aperture, generation rubble blocking big gun hole can be prevented effectively from again.
The technical solution used in the present invention: a kind of blast hole projectile filling device that can be used for different pore size, including a funnel for feeding, the middle part of described funnel is provided with step, the lower port surrounding of funnel uniformly has 4 grooves, groove one end is provided with bearing pin, is provided with moving block respectively through bearing pin in 4 grooves of funnel, has groove with moving block touching position in described funnel, being provided with spring bottom moving block, the described spring other end is fixed on groove.
As preferably, described step being provided with skid resistant course. So this device is just more firm, not easily rotates, and with the obstruct at funnel edge, the rubble around big gun hole is not easily accessible big gun hole, loads being directly placed into by explosive in funnel meanwhile, easy and simple to handle, time saving and energy saving.
As preferably, described moving block top is arc structure. Described moving block top is arc structure, reduces friction, it is simple to press-in.
Present configuration is simple, easy to manufacture, easy to use and reliable.
Compared with prior art, beneficial effects of the present invention is embodied in:
Adopting said apparatus, it is necessary to when loading explosive in big gun hole, by this device insertion big gun hole, in insertion process, the moving block in funnel trough is subject to the extruding of big gun hole wall, compresses spring pivotal, until in 4 moving block press-in big gun holes, and automatic and big gun hole tensioner. It is further continued for inserting this device, until step contacts with big gun hole end surface.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention is arranged in big gun hole;
In accompanying drawing: the 2-funnel 3-moving block 4-bearing pin 5-spring 6-groove 7-step 8-skid resistant course of 1-big gun hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further. At this it should be noted that be adapted to assist in for the explanation of these embodiments and understand the present invention, but it is not intended that limitation of the invention. As long as just can be mutually combined additionally, technical characteristic involved in each embodiment of invention described below does not constitute conflict each other.
Below in conjunction with accompanying drawing with embodiment to the new further instruction of this practicality.
As shown in Figure 1, a kind of blast hole projectile filling device that can be used for different pore size, including a funnel 2 for feeding, the middle part of described funnel 2 is provided with step 7, and the lower port surrounding of funnel 2 uniformly has 4 grooves, and groove one end is provided with bearing pin 4, respectively through bearing pin 4, moving block 3 is installed in 4 grooves of funnel 2, having groove 6 with moving block 3 touching position in described funnel 2, be provided with spring 5 bottom moving block 3, described spring 5 other end is fixed on groove 6.
One preferred version of the present invention, described step 7 is provided with skid resistant course 8.
One preferred version of the present invention, described moving block 3 top is arc structure.
Adopting said apparatus, it is necessary in big gun hole during filling explosive, inserted by this device in big gun hole 1, in insertion process, the moving block 3 in funnel 2 groove is subject to the extruding of big gun hole wall, and compression spring 5 rotates, until 4 moving blocks 3 are pressed in big gun hole, and automatic and big gun hole tensioner. It is further continued for inserting this device, until step 7 contacts with big gun hole end surface.
Above in association with accompanying drawing, embodiments of the present invention are explained in detail, but the invention is not restricted to described embodiment. For a person skilled in the art; when without departing from the principle of the invention and spirit; these embodiments are carried out multiple change, amendment, replacement and modification; when still falling within spirit; these embodiments are carried out multiple change, amendment, replacement and modification, still falls within protection scope of the present invention.
