Description
Technical field
The present invention relates to bulk material conveying technology field, more particularly to a kind of stacker-reclaimer.
Background technology
At present, circular piling materials take-out is widely used in the bulk thing of the industries such as coal, grain, building materials, work, electric power and metallurgy
Material storage and conveying.Existing stacker-reclaimer includes take-off assembly and the top windrow component located at take-off assembly, to ensure heap
Material component is effectively supported, and existing mode is, in the support column of the centrally disposed support windrow component of feeding bucket of take-off assembly, to adopt
Used in the mode of the centrally disposed support column of feeding bucket so that bulk cargo can only be conveyed from the side of feeding bucket so that feeding bucket it is upper
Port bore is big, and in order to meet discharging requirement, the angle of discharge of feeding bucket need to reach certain angle (being usually 60 °), and it causes
Hopper height is taken to be designed to height.Because feeding bucket size is big, height is high so that the feeding transfer passage below feeding bucket
The deep position in underground must be sunk down into, big feeding transfer passage excavation amount, build cost height, long construction period is caused, and set
The reclaiming conveyer in feeding transfer passage is put because set location is deep, the design of explosion prevention function need to be considered, cost is high；Together
When, reclaiming conveyer climbs angle when conveying material to ground transfer station from feeding transfer passage to meet reclaiming conveyer
It is required that (being generally less than 16 °), the whole length of reclaiming conveyer is long so that transfer station is remote apart from stock ground center, while so that defeated
The ribbon conveyer and admission trestle bay for sending material are big, cause that the overall space-consuming of existing stacker-reclaimer is big, cost is high, build
If the cycle is long.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art to reduce reclaimer there is provided one kind to take sky
Between, the low stacker-reclaimer of cost.
In order to solve the above technical problems, technical scheme proposed by the present invention is：
A kind of stacker-reclaimer, including windrow component and the take-off assembly below windrow component, the take-off assembly bag
