Bucket-type reloading mine car is to connect several minecarts in series, and the two sides of the car body form two parallel long tracks by overlapping movable arms. A bin-type trolley with four rollers filled with minerals runs on it. Unload the coal mining car one by one.
The volume of the bin-type trolley can be equal to or one-half of the volume of the mine-cart; for each full-filled one, the bin-type trolley will go back and forth once or twice.
The use of bucket type narrow guage mine car in the excavation of single-track single-head roadways can save a lot of shunting time. There are two all-steel-structured carts with cylinders in the lower part of the cart; there are two types of narrow-gauge and quasi-gauge.
When using a bucket typenarrow guage mine car, an air compressor is installed on the traction locomotive or at the unloading location. When the cargo needs to be tipped, compressed air is introduced into the cylinder. For mines with a unified compressed air pipeline network, pipeline pressure can also be used for unloading. This kind of narrow guage mine car has a long service life and a small maintenance workload.
