The method for filling the explosive barrel in the prior art comprises the following steps: the method comprises the steps that a plurality of explosive barrels are tied on a bamboo pole in advance, a worker roughly controls the distance between the explosive barrels according to construction requirements, after the explosive barrels are tied, the worker stretches the bamboo pole and a string of explosive barrels on the bamboo pole into a blast hole, then sand and soil are filled into the blast hole, and finally the explosive barrels are detonated. The drawbacks of this filling method are: 1. all explosive barrels need to be bundled by workers on site, and the efficiency is low; 2. the distance between the explosive barrels is roughly measured and determined by workers during binding, even a plurality of workers bind the explosive barrels after only observing the distance by eyes, and the distance between the explosive barrels is difficult to control accurately; 3. the bamboo pole is smooth, the explosive barrel is generally not firm enough when being bound on the bamboo pole, and after the bamboo pole is thrown into the blast hole, workers backfill sand into the blast hole to easily impact the explosive barrel, so that the explosive barrel slides and deviates from the original position; 4. the detonating cords of all explosive barrels are exposed, so that the detonating cords are easily damaged when sandy soil is backfilled, and normal detonation is influenced.
Disclosure of Invention

In order to solve the technical problems, the technical scheme adopted by the invention is as follows: an explosive loading mechanism comprises a main rod, an explosive barrel and a shovel blade;
a hollow cavity is formed in the main rod, and a plurality of mounting holes are uniformly formed in the side surface of the main rod along the length direction;
one or more pin shafts are arranged on the side surface of the explosive barrel, and the explosive barrel is inserted into the mounting hole of the main rod through the pin shafts; if the number of the pin shafts on the side surface of the explosive barrel is multiple, the distance between the pin shafts is equal to the integral multiple of the distance between the mounting holes;
the head of the shovel blade is sharp and the shovel blade can be inserted into the cavity of the main rod;
when the explosive loading mechanism is used, a plurality of explosive barrels are fixed by using the pin shafts and the mounting holes, so that the explosive loading mechanism is convenient to mount; the distance between the explosive barrels is determined by the number of the mounting holes at intervals between the explosive barrels, and the on-site measurement or visual estimation of workers is not needed; after the explosive barrels are installed, all the explosive barrels are conveyed into the blast holes by using the main rod, and then, the sand is filled back to fix all the explosive barrels; and then, inserting the shovel blade into the cavity of the main rod, shoveling off all pin shafts, and pulling out the main rod for the next blast hole.
Further, the cross-section of mobile jib is ring sector, and the side shape of mobile jib matches with the side shape of circular explosive barrel, increases the area of contact between mobile jib and the explosive barrel, improves explosive barrel's stability.
Furthermore, the explosive loading mechanism also comprises a guide pipe, the length of the guide pipe is consistent with that of the main rod, the detonating cords of all the explosive barrels penetrate through the guide pipe, and the guide pipe is used for protecting the detonating cords.
Furthermore, the guide pipe is made of plastic and is of a split structure, the guide pipe comprises a first half pipe and a second half pipe, the cross section of the first half pipe is semicircular, and a through hole for the detonating cord to pass through is formed in the inner wall of the first half pipe; during installation, the detonating cords on all explosive barrels are first passed laterally through the through-holes of the first half-pipe, and then the second half-pipe and the first half-pipe are combined into a complete conduit.
Further, the main rod is made of hard plastic or steel.
Furthermore, the top cover of the explosive barrel is conical, so that backfilled sandy soil can fall downwards.
Has the advantages that: (1) according to the explosive loading mechanism, the main rod and the mounting holes uniformly distributed on the main rod are utilized to quickly fix the explosive barrels, so that workers can conveniently and quickly fill the explosive barrels into the blast holes, the distance between the explosive barrels is accurately controlled by means of the mounting holes, and the explosive loading efficiency is obviously improved. (2) According to the explosive loading mechanism, the cavity is formed in the main rod, the shovel blade extending into the cavity can cut off the pin shaft to separate the explosive barrel from the main rod, workers can conveniently pull out the main rod before the explosive barrel is detonated, the main rod is reused, and the cost is reduced. (3) According to the explosive loading mechanism, the section of the main rod is in the shape of a ring sector, and the local part of the explosive barrel is embedded into the main rod, so that the stability of the explosive barrel is improved. (4) The explosive loading mechanism is provided with the guide pipe to protect the detonating cord, so that the detonating cord is prevented from being damaged in the sand backfilling stage, and the detonation work is ensured to be carried out smoothly.
