Embodiment 1

[0013] Depend on Figure 1~3 As shown, the conveying system is composed of a mobile rotary unloading vehicle 1, a belt conveyor 2, a gravity balance mechanism 3, a tower frame 4, a platform 5, a mobile lifting rotary crane 6, and a mobile traction crushing vehicle 7; the tower frame 4 is a multi-section The trusses are connected sequentially. The lower part of the tower 4 is placed in the guide shaft of the mobile elevating and slewing crane 6 and is fixedly connected with the crane; On the bottom plane; multi-layer platforms are arranged on the tower 4 (according to the terrain of the mining area), and the vertical distance between the two platforms on the tower 4 is 8-10 meters; each platform is arranged with a belt conveyor 2, each The transmission part of the belt conveyor 2 is respectively installed on the multi-layer platform of the tower 4, the transmission part of the belt conveyor 2 is located in the middle of the belt conveyor 2, and the belt of the belt conveyor 2 i...

Embodiment 2

[0020] The difference between this embodiment and Embodiment 1 is that the traction device 8 is composed of a circular link chain and a tension rod indirectly connected. The tension rod is used to reduce the cost, and the tension rod is used in the linear tension section.

[0021] The mobile rotary unloading vehicle 1, the belt conveyor 2, the mobile lifting rotary crane 6 and the mobile traction crushing vehicle 7 of the present invention belong to the supporting equipment of this conveying system, and all are prior art products.

Abstract

The invention relates to a conveying system for open-pit mines, in particular to a stripping, backfilling and conveying system for open-pit mines, which is used for conveying stripped matters in the open-pit mine and backfilling the stripped matters into a goaf. At present, the stripped matters in the open-pit mines are conveyed and backfilled by a self-discharging truck and spirally transported along a road in a mining area; and as the mining area is poor in road conditions and has more ups and downs, compared with a continuous conveying device, the transportation efficiency is low and the cost is high when the self-discharging truck is adopted. A main body of the system is a tower frame, a rubber belt conveyor is arranged on the tower frame, the loading end of the rubber belt conveyor is connected with a mobile traction breaking vehicle, and the unloading end of the rubber belt conveyor is connected with a mobile rotary unloading vehicle. The lower part of the tower frame is fixedly linked on a mobile lifting revolving crane. The system disclosed by the invention can improve transportation efficiency, shorten transportation distance and reduce transportation cost by fully utilizing the height difference between a stripping region and a backfilling region of the open-pit mine and changing the single-vehicle transportation by the self-discharging truck along the spiral ups and downs of the road in the mining area to the downward or straight linear continuous transportation by the conveying system.

Description

technical field [0001] The invention relates to a transportation system for an open-pit mine, in particular to a stripping and backfilling conveying system for an open-pit mine, which is used for transporting stripped objects in the open-pit mine and backfilling them to the goaf. Background technique [0002] At present, dump trucks are used to transport and backfill stripped materials in open-pit mines, and they are transported in circles along the roads in the mining area. Due to the poor road conditions and many ups and downs in the mining area, compared with continuous conveying equipment, the use of dump trucks is more efficient and cost-effective. Contents of the invention [0003] The purpose of the present invention is to provide a stripping and backfill conveying system for open-pit mines, which solves the problem of high transportation efficiency and low cost of dump trucks; The spiral undulating bicycle transportation along the road in the mining area is the dow...
