Description

A trolley for blasting hole filling

technical field

The invention belongs to the technical field of blasting tools, in particular to a trolley for filling blast holes.

Background technique

Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in air, water, earth and rock media or objects to achieve the intended purpose. When the explosive package or charge explodes in the earth-rock medium or structure, the earth-rock medium or structure will be compressed, deformed, destroyed, loosened and thrown. It is mainly used for earthwork engineering and demolition of buildings. Open-pit and underground mining and underground excavation generally adopt medium and deep hole blasting. The blasting methods are strip charges, multi-charges, and delayed blasting. During the actual excavation process, drilling equipment must be used in advance according to the actual conditions of the blasting site. A certain number of blastholes arranged in a certain way are used to load explosives, and after the explosives are loaded, it is necessary to use blasthole filling materials such as sand to block the blastholes, so as to realize blasting.

However, manual filling is a waste of manpower, so a kind of trolley for filling blastholes has appeared, such as the patent application number 201621470370.2, which discloses a kind of trolley for filling blastholes, including a bucket and wheels, around the bucket The upper ends of the side walls are all inclined outwards, the bottom wall of the car bucket is funnel-shaped, and the lower end of the bottom wall is a discharge port. The first support frame, the second support frame and the pounding column are arranged in the car body. The first limit ring, the second limit ring is provided on the second support frame, and the first limit ring, the second limit ring and the discharge port are located on the same central axis, and the tamping column slides up and down on the car bucket and cooperate with the first limit ring, the second limit ring, and the discharge port. The outer wall of the pounding column is provided with a limit block to prevent it from slipping out of the vehicle body from the discharge port; With the mouth facing the blast hole, lift the tamping column, the stuffing material will fall to the blast hole through the discharge port, and press down on the tamping post to block the discharge port. The operation is simple and convenient, and the efficiency of blocking the blast hole is high, saving time and effort. Passing the column back and forth through the vent effectively prevents clogging of the vent.

The inventor found that the above-mentioned patents have the following problems in use: when filling the blasting hole, the material is only fed downward through the groove on the tamping column, and sometimes the outlet may be caused by the high pressure in the bucket. Blockage will affect normal use, and when the ramming column is pushed down to the bottom, the bottom of the ramming column may protrude downward from the car base, which may cause inconvenience when moving.

Therefore, in view of this, the existing structure and defects are studied and improved, and a trolley for blasting blasthole filling is provided, in order to achieve the purpose of having more practical value.

Contents of the invention

In order to solve the above-mentioned technical problems, the present invention provides a trolley for blasting blast hole filling, to solve the problem that when the above-mentioned device is filling the blast hole, it only feeds downward through the groove on the tamping column, and sometimes it may be damaged due to the The high pressure inside will cause the outlet to be blocked, affecting normal use, and when the tamping column is pushed down to the bottom, the bottom of the tamping column may protrude downward from the car base, which may cause inconvenience when moving question.
