Description

Railway bulk grain transportation and loading equipment

Technical Field

Background

Grain logistics is an important supporting link for grain industry operation, railway transportation is one of main modes of grain transportation in China, and the rail transportation occupies an important position in grain provincial-crossing transportation. At present, the railway grain transportation modes in China mainly comprise three modes: traditional bag grain transportation, bulk grain transportation and grain container transportation.

In recent years, in order to further realize the modernization of railway grain logistics, boost the improvement of grain circulation efficiency, the reduction of railway grain logistics cost and the promotion and enhancement of national emergency regulation and control capability on grain markets, railway departments accelerate the revolution of promoting the transportation of grains from package grain transportation to scattered storage, scattered transportation, scattered loading and scattered unloading transportation. The bulk grain transportation becomes a main transportation mode of grain circulation by opening a bulk grain transportation special line, pushing a loading and unloading machine to improve towards an automatic control direction and the like.

The bulk grain transportation has the following characteristics: the efficiency is high: because of using special operation machinery, mechanization is realized in the whole process of storage and transportation, so that the efficiency of bulk grain transportation is obviously higher than that of grain-wrapping transportation. Secondly, the cost is low: the bulk grain transportation directly reduces the packaging cost in the grain transportation process. Consumption is less: the bulk transportation adopts the fully-closed special wagon, so that the loss is basically avoided, and besides the non-pit force, the defects of theft, wet loss, fouling, insect and mouse damage and the like which are often caused in the bag transportation process are basically avoided.

At present, a plurality of bulk grain transportation in railway freight yards adopt common belt conveyors for loading and unloading, and the following problems mainly exist: the efficiency is low: after one section of carriage is filled, when a second section of carriage needs to be loaded and unloaded, the common belt conveyor is manually moved through wheels, the labor intensity of operators is high, and the loading and unloading efficiency is low. Secondly, the universality is poor: the height of the common belt conveyor is not adjustable, each loading and unloading device can only be suitable for fixed train models, and the universality is poor. Thirdly, electric transverse movement cannot be realized: the belt feeder needs the manual work just can remove after rotatory certain angle with equipment whole when removing, removes and just can load again after reaching the target in place and need reseing. Fourthly, uniform distribution cannot be realized: after ordinary belt feeder loading, the phenomenon of "going sharp" can appear in bulk grain, and the present operation is through the manual flat top that carries on, and operating personnel intensity of labour is big, wastes time and energy, and has certain potential safety hazard. And fifthly, multi-station unloading cannot be realized: the common belt conveyor can only realize loading and unloading at a fixed point, and when loading the same carriage, the common belt conveyor needs to be stopped for many times to change the position of the belt conveyor so as to realize loading operation at different point positions.
