Flow-type multi-purpose bulk cargo spiral stacking machine

Abstract

The invention discloses a flow-type multi-purpose bulk cargo spiral stacking machine, aims to realize stacking, shipment and loading of bulk cargos. The spiral stacking machine is in contact with the ground through a vehicle body assembly; a material receiving device of the spiral stacking machine is positioned at the middle of the vehicle frame of vehicle body assembly, and can receive a material discharged from a dump truck and other devices on the two sides of the spiral stacking machine (without an unloading platform); a spiral material transferring system conveys the material in the material receiving device to a folding belt conveyor mounted on a rotating platform hinged support; and through the rotating, luffing and folding functions, rotating, luffing and wide-range stacking of the material can be realized, and then multi-purpose flow-type bulk cargo stacking operation can be realized. The spiral stacking machine is very high in trafficability and vehicle stability, and has the advantages that the operation efficiency can be improved, the higher stacking height requirement can be met, and then the stacking field utilization ratio can be improved.

Description

technical field [0001] The invention relates to equipment for bulk material stacking, ship loading and vehicle loading, in particular to a mobile multipurpose screw stacking machine for bulk cargo. Background technique [0002] At present, in dealing with bulk bulk storage problems, in addition to using bucket wheel machines and cantilever stackers and other professional large-scale bulk storage equipment, for open-air bulk storage yards, users mostly use (1) loaders and belt conveyors Combined intermittent bulk material accumulation method; (2) dump truck and loader combined stacking process, the process flow is that the dump truck unloads the materials to the ground, the loader stacks them to form the bottom pile, and then the dump truck climbs up When unloading on the bottom stockpile, the excavator pushes the top of the stockpile flat to form a platform for the dump truck to walk on. This cycle gradually increases the height of the stockpile; (3) For the storage of bulk ...

AI Technical Summary

Problems solved by technology

Stacking process (1) Due to the large length and size of the belt conveyor, the flexible mobility of the equipment is poor, which makes it difficult to load and unload vehicles in the yard, making the operation efficiency low; secondly, this process often stores materials in multiple piles, and the multi-pile storage method The utilization rate of the storage yard is only two-thirds of the utilization rate of the trapezoidal continuous storage yard, which makes the utilization rate of the storage yard low, especially in the case of large inventory, the problem of the utilization rate of the storage yard is more prominent

Both (2) and (3) have high energy consumption, low efficiency, a lot of equipment, low utilization rate of storage yard space (low storage height), potential safety hazards (excavator slipping from the material pile), Fuel emission pollution, high fuel consumption costs, etc.

As for the loading and unloading process of bulk cargo, the combined loading and unloading methods of dump trucks, unloading platforms, receiving hoppers, fixed belt conveyors and barges are currently mainly used. In this loading process, the dump truck unloading platform occupies a large space at the front of the wharf, Problems such as the high energy consumption of the dump truck climbing onto the unloading platform, the waiting time of the system during the barge movement during the loading process, the high energy consumption of the dump truck and the pollution of fuel emissions, etc.

Aiming at the problems of bulk material stacking height and loading on ships or trucks, there is no good solution at present, especially there is no multi-functional mobile specialized bulk cargo stacking equipment that can effectively solve this problem
