Problems solved by technology

[0005] Bottom mine car rail transportation has high working efficiency and strong carrying capacity; but it requires more infrastructure work and more complicated supporting equipment, occupies a larger working area, has the worst mobility, and is difficult to adapt to the gangue stacking site ever-extending needs

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] The first embodiment is an automatic gangue unloading line for an average daily discharge of 1,000 tons of gangue, where the gangue output distribution point is 1 km away from the gangue centralized stacking point, see figure 1 with 2 .

[0031] This example gangue automatic unloading line track 18 parts, laying retracking. The bottom unloading mine car that runs on track weighs about 2500Kg, and the compartment 21 payload that adds weight increases 7000Kg. The beginning of the track is set at the gangue collection and distribution point, and the end of the track is higher than the beginning. Combined with the site terrain along the line, a downhill slope angle of about 9-21 degrees is maintained from the end to the beginning. Far from the terminal, there are 2×185kw double-drum hoists, the front ends of the two bottom-loading mine ca...

Abstract

The invention relates to an automatic unloading line for recrement, and belongs to material conveying equipment. The automatic unloading line mainly takes a multiline reciprocating track with a track unloading segment, and a weighted and heighted automatic dumpbottom transfer truck as an initial segment of the automatic unloading line, and takes guide channels (5, 6, 7 and 8) and a feed mechanism (14) which receive the output of unloaded materials, and two or more stages of belt type conveying (9, 11) which are key components as a tail segment of the automatic unloading line. The working tail end of unloading components of the unloading segment is the terminal of track transportation; the unloading segment supports the bearing surface and the horizontal plane of the transfer truck, and keeps supporting the inclination of a lift angle (alpha) in the operating direction; the lift angle takes sliding power which makes the transfer truck staying on the lift angle generate back stroke and the unloading components of the transfer truck reset as the limit; and the track keeps truck sliding gradient which can make a unloaded transfer truck return in the whole stroke. The bidirectional use of the unloading segment skillfully provides possibility of reciprocating work, obviously reduces occupied area and simplifies a structure; the belt type conveying strengthens maneuverability of the unloading line; and the automatic unloading line for the recrement has the advantages of reasonable proposal conception, deft design, high efficiency, low consumption and convenient management.

Description

technical field [0001] The invention belongs to material conveying equipment, and mainly relates to the change of the conveying mode and the improvement of the structure of the conveying equipment. Background technique [0002] Nowadays, coal mining enterprises often use vehicles to transport or dispatch winches to pull side-dumping mine trucks to dump gangue to remove or centrally stack gangue that needs to be transferred. Automobile transportation is convenient and fast, and basically does not require other supporting infrastructure, which is easy to implement, easy to operate and manage; but it is still difficult to complete the centralized task of gangue transfer with only automobiles, and the follow-up treatment of transshipment materials is still required. [0003] The method of dispatching the winch to pull the side dumping mine car to dump the gangue is more efficient, but it is necessary to lay the corresponding mine car track, install the winch, and equip the corre...
