Abstract

The utility model discloses a mine loading vessel, used for loading coiled explosive in the coal mine roadway and tunnel excavation rock-drilling blasthole. A protective cover is arranged at one end of an explosive protection tube, a push rod is arranged in the explosive protection chamber on the explosive protection tube, an explosive pushing head is arranged at one end of the push rod, the other ends of the push rod and the explosive tube can be prolonged and connected with an extension rod and an extension tube, and graduation length marks are arranged on the outer surface of the explosive protection tube. The utility model overcomes the problems that if a wooden stamping rod is used for pushing coiled explosive to a drilled blasthole, the stencil paper for packing the coiled explosive is easy to be broken when being worn with the wall of the blasthole, and the push depth is invisible and unclear, finally the blasting is affected. In the utility model, the coiled explosive is put in the explosive protection chamber and together pushed into the drilled blasthole, thereby the stencil paper of the coiled explosive is prevented from being worn with the wall of the blasthole and broken, also prevented from being broken by overlarge push force if the wooden stamping rod is used, meanwhile the graduation marks can be used for clearly displaying the depth of the coiled explosive in the blasthole; a plurality of coiled explosive can be pushed into the blastholes at one time and the blasting efficiency is improved. The utility model has the advantages of simple operation, security, reliability and high loading speed.

Description

Mining explosive loader

Technical field the utility model relates to a kind of mining explosive loader, is used for coal mine roadway, tunnel piercing driling explosion borehole is dressed up the volume explosive.

Background technology is present, when coal mine roadway or tunnel piercing, mostly be filling rolling explosive in pre-drilled borehole, implement driling explosion, no matter be the time to level or for the inclined drill blashole charge, main use wooden tamper, that is: earlier powder stick is put into the borehole that has bored during powder charge, powder stick is pushed desired location with wooden tamper.There is following problem in this method: because the paraffin paper parcel is used in the periphery of powder stick, in the middle of the process that pushes powder stick, peripheral paraffin paper directly contacts and produces friction with the wall of a borehole, distance is longer when pushing, powder stick paraffin paper is broken, cause explosive to leak outside, influence demolition effect; When wooden tamper propelling movement powder stick runs into rock grain or rock dust obstruction, must strengthen the extruding force of wooden tamper in order to make powder stick push away bar to powder stick, increased the deformation extent and the drug delivery difficulty of powder stick; The depth location of pushed powder stick be can not determine to determine whether this powder stick has delivered to the position of expection, causes the powder stick spacing excessive easily simultaneously, disconnected quick-fried phenomenon occurs.When propelling movement has the powder stick of detonator, there is the extruding force of wooden tamper the big gun line pressure might be broken by big gun line crust badly broken more in addition, is prone to disconnected quick-fried because powder stick and hole wall friction make more greatly.

Utility model content the purpose of this utility model provides a kind of mining explosive loader for people exactly, it can be put into powder stick in advance to protect to put it in the pencil and bore in the good borehole, promote push rod again medicine is sent in the hole, and show the powder stick depth location by protecting pencil and push rod high scale.

The purpose of this utility model is to realize by following technique measures:

Comprise and protect pencil, push rod and protect the coyote hole composition, be that the pencil that protects that protects coyote hole is arranged, at Guan Yiduan assembling protecting cover, the other end have internal thread can with protect pencil and take over and to be connected, on pipe, protect and assemble push rod in the coyote hole, one end of this bar have be coarser than the body of rod push away the medicine head, the other end has external screw thread to be connected with the push rod extension bar, protects pencil and the push rod outer surface all has the scale length coding.

Describedly protect pencil to take over an end be external screw thread, the other end is an internal thread.

Described push rod extension bar one end is an external screw thread, and the other end is an internal thread.

Advantage of the present utility model; when using this mining explosive loader powder charge; can earlier powder stick be placed in the coyote hole; to protect pencil then sends in the boring borehole together with powder stick; owing to protect the protection of pencil, avoided the friction of powder stick paraffin paper and the wall of a borehole and paraffin paper and tube wall friction less, make powder stick be protected; be difficult for breaking, thus more complete.When using this device drug delivery, powder stick when protecting pencil and be the bearing object of bearing axial propelling movement power rather than wooden tamper drug delivery, thereby powder stick is not squeezed and length shortens has also been avoided being broken by the thrust of wooden tamper is excessive, has kept powder stick complete.Protect length scale coding is arranged on the pencil, make the workman when powder charge, can determine the depth location of powder stick in boring, be easy to control the spacing of powder stick, make the workman know the distance between the powder stick like this, improved the operability of discontinuous charge explosion method, actual demolition effect makes moderate progress, because of the clear and definite use amount that also reduces explosive of distance.When using the continuous charging explosion, disposable the sending in the boring of the disposable charging room of packing into earlier of a plurality of powder sticks needn't can be sent by a volume one in addition, improved powder charge speed, shortened the time of powder charge, improved operating efficiency.When propelling movement has the powder stick of detonator, the big gun line can be put into pillar, avoided of the wearing and tearing of big gun line, and the big gun line is less in the friction of protecting pencil, makes that the big gun line is protected, and has strengthened the explosion transfer performance of big gun line in hole wall.Have characteristics such as simple to operate, safe and reliable, that powder charge is quick.

Description of drawings elaborates to the utility model below with reference to accompanying drawing:

Fig. 1 is that the utility model is analysed and observe the assembling schematic diagram.

Fig. 2 is the utility model assembling profile schematic diagram.

Fig. 3 is that the utility model protects pencil adapter schematic diagram.

Fig. 4 is the utility model push rod extension bar schematic diagram.

The specific embodiment is by shown in Fig. 1-4, comprise and protect pencil 1, push rod 2 and protect coyote hole 4 and form, be have that a band protects coyote hole 4 protect pencil 1, end at pipe is equipped with the movable protecting cover 3 of energy, the other end have internal thread can with protect pencil and take over 7 external screw threads and be connected, this protects pencil, and to take over 7 one ends are external screw threads, the other end is an internal thread, on pipe, protect assembling push rod 2 in the coyote hole 4, what one end of this bar had that diameter is coarser than the body of rod pushes away the medicine head, and the other end has external screw thread to be connected with push rod extension bar 8 internal threads, and push rod extension bar 8 one ends are external screw threads, the other end is an internal thread, and protecting pencil 1 all has with scale 6 expression length codings with push rod 2 shell surfaces.
