For the work of loading fluid explosives such as sives) with an air-loading machine, insert the fluid explosive loading hose into the blast hole by hand, pull out the hose by hand while conveying the explosive with compressed air, and place it in the blast hole appropriately. Stop the air at the correct position.

る。When the charging is completed in this way, the tip of the hose is moved to the next blast hole and the next explosive loading operation is started. Depending on the model of the loading machine, the above-mentioned work may be a two-step operation of cleaning the blast hole by blowing compressed air and charging.

るので、健康上も望ましくない。These operations are conventionally performed manually, and the charging start position, the stop position, and the withdrawal speed of the explosive loading hose are mostly performed by the operator's intuition, so that there are many variations. Putting in and out of the hose also requires repeated physical labor. Moreover, since it must be carried out near the blast hole for charging, the human body is repeatedly blown with explosive charges, which is not desirable for health.

The air-loading machine automatically fills the explosive hole with the fluid explosive at an appropriate position. If a hose is inserted into the blast hole, if an obstacle is encountered due to roughening of the hole, or if a preset suitable resistance value of a pushing force of 20 kg or less is reached, the hose feed is slipped by the slip adjusting device. The safety is secured.

に挿入する。The hose feed roller device 4 includes, in addition to the feed driving roller 4a for the hose 2, the rollers 4 described above.
It has a slip adjusting device 7 for adjusting the gripping force of the hose by a and 4b. (See FIG. 2) Devices other than the operation panel 6 may be moved to the blast hole mouth by the moving device 8 by human power. Since the illustrated embodiment is configured as described above, the present device guided to the blast hole by the moving device 8 operates the hose feed roller device 4 by operating the switch of the operation panel 6 to operate the hose. The feed roller device 4 feeds the hose 1, or returns at a speed of 0.2 to 2 m / s.
ec is manually inserted into the blast hole of the hose while being manually selected, or automatically inserted at a preselected hose feed rate.

ホースは自動停止する。After that, the blow-off valve of the explosive loading machine is interlocked to open it, so that the inside of the blast hole is cleaned with compressed air. Then, the feed distance of the hose 1 at the inlet of the blast hole is read by the distance sensor 5, and when it reaches the bottom of the hole, hose feed slips and stops, and the depth of the blast hole is read. After that, the hose 1 is returned by the switch on the operation panel 6 and the idle valve is interlocked so as to stop the hose 1. When the hose 1 reaches the mouth, the hose automatically stops at the previously read distance.

作業が停止する。As described above, the blast slot is read by the distance sensor, and the master die is used (the dynamite is loaded with the detonator, and it is preferable to use a non-electric detonator such as a nonel detonator electrically). And feed it by operating the feeding device with the loading hose. Then, the feeding operation of the hose 1 is stopped in front of the butt of the hole according to the length of the parent die set in advance on the operation panel 6.

薬を孔内に掃き出させる。When the hose 1 automatically returns and reaches the explosive blowing start position (position returned by 0.5 to 1 m), the explosive blowing valve of the loading machine is automatically opened and the charging is started. Thus, when the blowing completion position is reached, the explosive blowing valve is closed and the transfer of the explosive from the loader is stopped. The empty blow valve opens automatically, and the residual explosive in the hose is swept into the hole.
