Self-unloading container

Abstract

The invention relates to a container for a mine, in particular to a self-unloading container with a bottom plate capable of being closed automatically. The container comprises a container body, and a frame for supporting the container body, wherein the lower part of the container body is provided with a tapered structure; a sliding bottom plate is arranged at the bottom of the container body; the frame consists of a vertical support bracket and a base frame; two support guiding slots for supporting the sliding bottom plate are formed on the vertical support bracket; an air cylinder 1 and an air cylinder 2 are arranged in a space between the sliding bottom plate and the base frame in the directions of the support guiding slots; cylinder body parts of the air cylinder 1 and the air cylinder 2 are both articulated with the base frame; and piston rods of the air cylinder 1 and the air cylinder 2 are both articulated with the sliding bottom plate. With the adoption of the container, the quick transportation of a bulk material is realized; the auxiliary transportation operation time is shortened; and the transportation work efficiency is improved.

Description

technical field [0001] The invention relates to a container for mines, in particular to a container capable of self-unloading and whose bottom plate can be automatically covered. Background technique [0002] At present, in the trackless auxiliary transportation system of coal mines, there are mainly three methods for the transportation of bulk materials. One way is to use trackless rubber-tyred vehicles to realize one-stop transportation from the ground to the underground, that is, use a loader to directly load the sand, stones and other bulk materials required underground into the rubber-tyred vehicles at the mine flooring site, and then the rubber-tyred vehicles It is lowered from the auxiliary well to the bottom of the well, and the rubber-tyred vehicle that reaches the bottom of the auxiliary well drives out of the cage and delivers the materials to the designated place according to the plan. After unloading, the rubber-tyred vehicle drives into the cage from the botto...

Problems solved by technology

[0003] In the first mode of transportation, the rubber-tyred vehicles need to be lifted or lowered through the lifting cage of the auxiliary shaft every time. Due to the heavy weight of the rubber-tyred vehicles, the mine hoist system consumes a lot of electric energy in the process of repeatedly lifting the rubber-tyred vehicles , adding ancillary transportation costs

In the second mode of transportation, it is necessary to build a silo with a certain volume at the bottom of the well, while digging a chamber and building a silo underground has a long cycle and high cost, which also increases the auxiliary transportation cost

The third method needs to use two cranes for unloading operation, the operation is complicated, the lifting and unloading operation takes a long time, the material is easy to spill outside the rubber-tyred vehicle, and improper lifting operation of the crane will cause the mine car to fall off the hook, resulting in a safety accident
