Material taking device and pile material taking method

Abstract

The invention relates to a material taking device and a pile material taking method. The material taking device at least comprises a rack and a material combing device. One end of the material combingdevice is connected with the rack through a connecting mechanism. The material combing device comprises a material combing rack and a main material rake arranged on the material combing rack. The main material rake comprises a plurality of main material comb teeth. The main material comb teeth are distributed along the material combing surface of the material combing rack in the manner multiple arrays. The every two adjacent arrays of main material comb teeth are arranged in an alternate manner. According to the material taking device and the pile material taking method, because the multiplearrays of main material comb teeth are arranged in the width direction of the material combing rack, and the every two adjacent arrays of main material comb teeth are arranged in the alternate manner,the type of stress of the working plane, on the surface of materials, of the material taking device during material taking and combing operation is improved, the effect of material combing is improved, the efficiency of material taking can be effectively improved, and the material taking device is particularly applicable to the places for carrying out operation on viscous materials, and has the good loosening effect on the materials with strong viscosity.

Description

technical field [0001] The invention belongs to the technical field of loading and unloading, and in particular relates to a material reclaiming device and a stacking and reclaiming method. Background technique [0002] The bridge reclaimer is a continuous and efficient bulk material loading and unloading conveying machine, and it is the reclaiming equipment for the raw material pre-homogenization long stockyard in the cement plant. There is a bridge-type reclaimer combing device. A combing device is installed on the main beam of the bridge-type reclaimer. There are multiple rakes on the comb-type reclaimer. The bridge-type reclaimer is installed on the pre-homogenization long On the track of the stockyard, the material is taken from the end face of the stockpile in the center of the stockyard, and the combing device is adjusted to a certain angle according to the angle of repose of the stockpile. The material loosening rake loosens the material on the end face of the mater...

Problems solved by technology

However, due to structural limitations, the wire ropes on both sides cannot move across the entire section, but can only move on both sides of the stockpile, so the effect on the entire stockpile is limited, especially on large bridge-type scraper reclaimers due to the wide section of the stockpile. 1. The size of the material rake is large, and its disadvantages are more obvious at this time. In the end, the same problem as the first structure range will seriously affect the production.

[0004] In addition, in the stacking process of the storage yard, the maximum stacking capacity is usually designed, and then the unloading member of the stacking device is fixed at the apex of the maximum stacking capacity for unloading. After the unloading is completed, the scraper machine takes out the material ; However, often the incoming material in the storage yard is not the designed maximum stacking capacity, or the material needs to be taken out if the maximum storage capacity is not reached, or some materials are taken away and then stacked and the material needs to be taken out if the maximum storage capacity is not reached, such as Figure 8-10 At this time, the stockpile cannot completely fill the stockyard with materials, and the stockpile type is not close to the discharge port. When the reclaimer starts to work, the working surface at the bottom cannot touch the stockpile, and part of the scraped materials cannot be scraped. After being picked up by the system belt conveyor and transported away, it can only be transferred to the discharge port in the material yard, and there is a problem of doing virtual work. This process is called flat material in the industry. This process is time-consuming, energy-consuming, waste of manpower, and increases Equipment wear and tear, reducing the operating life of equipment and increasing the workload of equipment maintenance
