Carry the side dump compartment of awning
Technical field
This utility model is related to grain storage mechanical equipment technical field, and in particular to a kind of side dump car for carrying awning
Railway carriage or compartment.
Background technology
Grain is the basic of mankind's existence, and Chinese population account for 1/5th of world population, food supply safety
Particularly important.But the Grain Logistics transportation equipment of China falls behind at present, governs grain logistics in puerperal modernization development, example
Such as, during grain storage and transportation, the method that the discharging of grain bulk vehicle is generally opened manually discharge port using envelope bottom, typically
The side door of grain bulk vehicle be arranged on the side plate of envelope, be divided into 3-5 and can open railway carriage or compartment door, each railway carriage or compartment door is required for a set of pulling
Latch mechanism, pulling latch mechanism during unloading needs all artificial unlatchings, and due to the special nature of bulk granular thing, railway carriage or compartment door can not be by artificial
Open, and general side enabling is whole door body, then car load grain all flows down for an enabling, does not apply to and bulk granular thing very much
Unload, and discharge rate can not be controlled;In addition existing grain bulk vehicle does not have awning, when thunderstorm weather is run into,
The top that cloth for keeping out rain is ridden over grain bulk vehicle that can only be artificial, for rain cover, prevents grain in bulk in-car in bulk
Grain is soaked by rainwater, and the obvious efficiency of this method is low, and artificial operation is more loaded down with trivial details, and at least needs two operators to complete.

Motor, reducing motor backwards rotation capstan winch are rotated, and fix bar pulls awning cloth to move forward, and opens when fix bar touches front limit
Guan Shi, reducing motor stop, and final awning cloth all collects the bottom in shed hood;
In addition, make to fix locking plate positioned at upside to upper rotary moveable locking plate before loading, due to grain side door sidepiece after loading
Pressure, rotary moveable locking plate makes to fix locking plate positioned at downside, and now side door is in locking state, and side door retaining mechanism is prevented
The telescopic oil cylinder pressure release of side door causes the unlatching of side door;
In sum, this utility model overall structure is simple, and manufacture is easy for installation, and envelope door-opening mechanism adopts all-hydraulic drive
Dynamic, it is time saving and energy saving to manipulate, and unloads efficient and convenient, it is adaptable to ship the middle-long distance fortune of the loose unpacked materials such as Oryza glutinosa, Semen Tritici aestivi and Semen Brassicae campestriss
Defeated, of many uses.
