Material piling and taking machine

Abstract

The present invention provides a stacker and reclaimer, comprising a stacker assembly and a reclaimer assembly arranged below the stacker assembly, the reclaimer assembly includes a reclaimer hopper and a reclaimer conveyor arranged below the reclaimer, the reclaimer A rotary platform is provided on the outer periphery of the hopper, and the stacking assembly is supported on the rotary platform. The invention has the advantages of reducing the occupied space of the reclaimer and low cost.

Description

technical field [0001] The invention relates to the technical field of bulk material conveying, in particular to a stacker-reclaimer. Background technique [0002] At present, circular stackers and reclaimers are widely used in the storage and transportation of bulk materials in coal, grain, building materials, engineering, electric power and metallurgy industries. The existing stacker-reclaimer includes a reclaimer assembly and a stacker assembly above the reclaimer assembly. In order to ensure the effective support of the stacker assembly, the existing method is to set a support stacker assembly in the center of the reclaimer hopper of the reclaimer assembly. The support column adopts the method of setting the support column in the center of the reclaiming hopper, so that the bulk material can only be conveyed from the side of the reclaiming hopper, so that the upper port of the reclaiming hopper has a large diameter. A certain angle (usually 60°) is reached, which result...

Problems solved by technology

The existing stacker-reclaimer includes a reclaimer assembly and a stacker assembly located above the reclaimer assembly. In order to ensure the effective support of the stacker assembly, the existing method is to set a support stacker assembly in the center of the reclaimer hopper of the reclaimer assembly. The support column adopts the method of setting the support column in the center of the hopper, so that the bulk material can only be transported from the side of the hopper, so that the upper port of the hopper has a large diameter, and in order to meet the discharge requirements, the discharge angle of the hopper needs to be Reach a certain angle (usually 60°), which leads to a high design of the height of the retrieving hopper

Due to the large size and high height of the retrieving hopper, the retrieving and conveying channel under the retrieving hopper must be sunk to a deep underground position, resulting in a large amount of excavation, high construction costs, and a long construction period for the retrieving and conveying channel. Due to the deep setting position of the reclaiming conveyor in the conveying channel, the explosion-proof function design needs to be considered, and the cost is high. Climbing angle requirements (generally less than 16°), the long length of the reclaiming conveyor makes the transfer station far away from the center of the stockyard, and at the same time makes the belt conveyor and the entry trestle for conveying incoming materials have a large span, resulting in the existing The stacker-reclaimer takes up a lot of space, high cost and long construction period
