Problems solved by technology

Although the production efficiency of reclaiming has been improved by setting up two sets of simultaneous reclaiming in two layers, but in a large number of practices, several defects of this kind of equipment have also been exposed: (1) limited by the scraper driving mode and The limitation of structural size restricts its production capacity. Under the current technology, its maximum reclaiming production capacity can only reach 3000m in the form of double scraper arm structure. 3 /h; (2) The scraper reclaimer is not suitable for use in the environment of relatively viscous materials, and the problem of viscous materials sticking to the scraper has not been well resolved; (3) The scraper reclaimer is not suitable for materials with large particle size and lumps In the case of too much material, the size of the material is too large and the block material is too large to easily damage the scraper and the scraper chain
Because the lifting beam of the bridge-type side scraper reclaimer is at the bottom of the material yard, the bucket wheel reclaiming operation must be assisted by the structural characteristics of the material rake, resulting in the following limitations in actual use: (1)...

Embodiment 1

[0094] figure 1 It is a schematic diagram of a preferred embodiment of the stacker-reclaimer provided by the present invention. The stacker-reclaimer can simultaneously complete material storage, stacking and taking out, specifically, as figure 1 As shown, the working environment of the stacker-reclaimer is a circular stockyard, and the bulk stockpile stored in it is an annular stockpile 100 with a trapezoidal top, and the stockyard is surrounded by a dome 200 and an annular retaining wall; With this example,

[0095] Such as figure 1 As shown, the bucket wheel stacker and reclaimer includes a revolving gantry part 10, a bucket wheel reclaiming part 20, a conveying part 50 and a centering turning part 30, wherein the revolving gantry part 10 takes the span of the revolving gantry part as a radius around the fixed The rotary part 30 rotates, and the bucket wheel retrieving part 20 and the conveying part 50 are connected to the revolving gantry part 10, wherein: the conveying ...

Embodiment 2

[0125] The difference between this embodiment and Embodiment 1 lies in the structure of the balance part 60 and the way and principle of realizing the balance of the cantilever beam 54 . Such as Figure 15 and Figure 16 As shown, in this embodiment, the balance part 60 includes a first pull rod 62 and a second pull rod 63 respectively arranged on both sides of the central axis 14, the first pull rod 62 is hinged with the central axis 14 and the cross arm 11 respectively, and the second pull rod 63 is hinged with central axis 14 and cantilever beam 54 respectively. The position where the first pull rod 62 is hinged to the cross arm 11 coincides with the position where the deformation of the crossbeam of the revolving gantry part 10 is the largest, thus, through the disturbance deformation of the crossbeam of the revolving mast part 10 itself, the balance of the conveying part 50 is provided. In this way, the dynamic balance of the entire conveying part can be realized withou...

Embodiment 3

[0128] The difference between this embodiment and Embodiments 1 and 2 lies in the structural form of the conveying part 50. By optimizing the structure of the conveying part 50, the two operations of retrieving and stacking are combined without additional cantilever beams 54 and balancing parts 60 and Connecting workpieces, etc., suitable for material yards where reclaiming and stacking are not carried out at the same time. What is more important is to realize the adjustable height of stacking material, the inventor has carried out further improvement for above-mentioned two preferred implementation modes, as Figure 17 and Figure 18 As shown, the delivery part 50 is located in the revolving gantry part 10 and rotates together, including a belt conveyor 51 for taking materials, a trapezoidal distribution conveyor 53, a trolley running mechanism 54 and a belt conveyor 56 for stacking, wherein the belt conveyor 51 for taking materials, Trapezoidal distributing machine 53, trolle...

Abstract

The invention discloses a bucket-wheel stacker-reclaimer. The bucket-wheel stacker-reclaimer comprises a rotary portal frame part, a bucket-wheel material taking part, a conveying part and a centering rotating mechanism, wherein the rotary portal frame part rotates around the centering rotating mechanism by taking a span of the rotating portal frame as the radius, and the bucket-wheel material taking part and the conveying part are connected to the rotating portal frame. The conveying part is composed of a plurality of belt conveyors and is matched with the bucket-wheel material taking part to form a material taking material flow channel and/or a material stacking material flow channel. Different from existing equipment, the stacker-reclaimer, taking the span of the portal frame as the actual working range radius, is applied to a round stockyard initiatively.

Description

technical field [0001] The invention relates to a stacker and reclaimer used in a circular stockyard, and more specifically relates to a bucket wheel stacker and reclaimer, belonging to the technical field of stacking and reclaiming equipment for bulk materials in a circular stockyard. Background technique [0002] With the increasing awareness of environmental protection and environmental protection requirements, reducing the pollution to the surrounding environment has become an urgent problem to be solved in large modern storage yards. At the same time, it is also necessary to avoid the impact of bad weather on the safe operation of the storage yard. Circular stockyard stacker and reclaimer is a kind of stacking and reclaiming equipment for bulk materials, usually arranged in circular stockyards. With economic development and social progress, environmental protection requirements are getting higher and higher. Circular stockyard stackers and reclaimers The application of ...
