Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a special batching hopper device for small and medium-sized mines. Background Art

[0002] At present, in the shotcrete support of underground tunnels and deep well tunnels supported by anchor spraying in mines and coal mines, the commercial concrete on the ground cannot be transported to the on-site wet spraying operation surface in time due to the special transportation conditions underground. Sand and gravel are often transported to the operation surface by mine cars through inclined shafts. Due to the uncontrolled transportation time, it is difficult to transport the mixed concrete on the ground to the on-site operation surface in time, thus failing to ensure the continuous construction of wet spraying underground. Due to the lack of material weighing equipment suitable for space constraints, it is impossible to establish a batching station underground, resulting in generally low efficiency of on-site concrete production and preparation. There are also problems such as inaccurate concrete batching measurement and unstable discharge quality, which is not conducive to the connection of subsequent concrete mixing processes, thus affecting the entire wet spraying process and seriously hindering the promotion of wet spraying technology and the improvement of construction efficiency.

[0003] Therefore, it is particularly important to develop a batching hopper equipment suitable for use in small and medium-sized tunnel mines and coal mines and which is easy to move, so as to solve the batching and metering problems in the process of preparing concrete on site underground, thereby ensuring the smooth process of the wet spraying process and improving the efficiency of underground construction.
