Description
Technical field
The utility model is a kind of fast quantification automation loading station of large loose unpacked material, is a kind of automation apron quantitive conveyor tool, a kind of railroad train loading machine.
Background technology
What adopted at known quickly ration loading station is surge bunker+quantitative storehouse scheme, and its basic arrangement is that two bins are arranged above and below, and promptly places surge bunker above quantitative storehouse, to solve the contradiction between static weighing, the quantitative and continuous entrucking.For example the automatic ration truck-loading facilities of Chinese patent 01201108.8 and Chinese patent 01280152.6 proposition all adopts this scheme.The shortcoming of this scheme is that the bin that two volumes differ bigger is arranged above and below, and generally all is double, i.e. two surge bunkers, two quantitative storehouses.System is too huge, complex structure, and the bin degree of utilization is not high; Because quantitatively the top in storehouse also has the surge bunker of bigger height, total system is higher, makes the sealing-tape machine head of fortune material very high, has increased the material loading difficulty; Because system is huge, the construction investment is bigger, has limited the use at quickly ration loading station to a certain extent.
Summary of the invention
Too huge for overcoming existing automatic loading station equipment, bin is too much, the problem that degree of utilization is not high, the utility model provide a kind of parallel placement surge bunker and quantitatively the storehouse and with surge bunker also as the continuous and quantitative loading station in quantitative storehouse.Described loading station adopts installs two quantitative storehouses abreast on same horizontal surface, promptly so-called two storehouses.Two quantitative storehouses are surge bunker each other, is used alternatingly, i.e. quantitative storehouse quickly discharging material entrucking, is weighed or filled the material back of weighing and wait for discharging at another quantitative storehouse material loading, thus realize accurately static weighing and fast continuously entrucking carry out simultaneously.Described method need only a bin height, greatly reduce the height of total system, fortune material sealing-tape machine height is reduced greatly.Loading speed also is improved simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: the fast automatic loading station in two quantitative storehouses comprises fortune material sealing-tape machine, freeing pipe, the steel structure pylon, dust keeper, transition chute, fan-shaped loading chute, hydraulic efficiency pressure system, weight correcting device, control cabin, also comprise four bifurcated chutes, batching gate, two quantitative storehouses of surge bunker each other, discharge gate, LOAD CELLS; Described going up transported the top that the material sealing-tape machine is installed in described steel structure pylon, described four bifurcated chutes are installed in described below of going up fortune material sealing-tape machine, the described discharge end of going up fortune material sealing-tape machine is aimed at the feeding mouth of described four bifurcated chutes, described two each other the quantitative storehouse of surge bunker be installed in the below of described four bifurcated chutes, four discharging openings of described four bifurcated chutes are aimed at the feeding mouth in described two quantitative storehouses respectively, the discharging opening in described two quantitative storehouses is connected with described transition chute feeding mouth by described dust keeper, described transition chute discharging opening is connected with described fan-shaped loading chute feeding mouth, described hydraulic efficiency pressure system and batching gate, discharge gate, the weight correcting device connects, described freeing pipe and suitable for reading connection of described quantitative storehouse, described weight correcting device is suspended on the both sides in described quantitative storehouse, and described control cabin is installed in described steel structure pylon bottom one side.
Quantitatively the storehouse comprises straight section, oblique section, supporting leg.Quantitatively top, storehouse is straight section, the bottom is oblique section, described straight section and oblique section are formed an asymmetric terrace with edge, described two quantitative storehouses are installed on the same horizontal surface, be installed in side by side on the steel structure pylon by described supporting leg, described LOAD CELLS is installed under the supporting leg, and the discharging opening bottom in described each quantitative storehouse is installed the described discharge gate of a cover respectively.Four bifurcated chutes have a feeding mouth and four discharging openings, and feeding mouth is a column type body, the upper end pan feeding, and the lower end is connected with four barrel shape chutes, forms four bifurcateds, and each discharging opening is installed a cover batching gate respectively.
Concrete working process of the present utility model is: after vehicle to be installed arrives at a station, start conveying system, material is sent in the quantitative storehouse of A through defeated material adhesive tape, measure weight in real time by the LOAD CELLS that is installed in the quantitative storehouse of A, when reaching predetermined weight, stop to have sent material, the material in the quantitative storehouse of A is carried out static accurate measurement to the quantitative storehouse of A.Simultaneously, defeated material adhesive tape is sent material into the quantitative storehouse of B, and in the pan feeding of the quantitative storehouse of B, the discharge gate in the quantitative storehouse of A is opened, and material is discharged into the compartment by fan-shaped loading chute in the quantitative storehouse of A.In the time of the quantitative storehouse of A discharging, B fills in quantitative storehouse, waits for discharging after static accurate measurement.After A quantitative storehouse emptying, the quantitative storehouse of A discharge gate cuts out when waiting for batching, and the quantitative storehouse of B discharge gate is opened, and the material in the quantitative storehouse of B is discharged into the compartment.Meanwhile defeated material adhesive tape begins to the quantitative storehouse of A batching, weighs, and performs and unloads the material preparation.Train is at the uniform velocity advanced in the entrucking process, and the compartment is at the uniform velocity by the entrucking position, and charging, weighing, discharging are taken turns in two quantitative storehouses, and cycle operation so continuously hockets, thus realize rapidly, continuously, accurately, dynamically entrucking.Train the continuously and smoothly advance, until having adorned the final section compartment.
The beneficial effects of the utility model are: the loading speed of loading station further improves, and the height of loading station reduces greatly, weight saving, reduced the number of bin, reduced the investment of loading station, Applicable scope is wider, is a kind of safe and reliable novel fast quantification automation loading station.Described two quantitatively storehouse automation loading station bicycle entrucking precision is 0.1%, and permutation car entrucking precision is ± 0.05%; The entrucking ability per hour can reach more than 5000 tons, and promptly train can guarantee continuous car loading operation so that per hour 0.8～1.5 kilometer speed is at the uniform velocity travelled, and satisfies the requirement of user to loading station loading speed and entrucking precision.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
