Abstract
The utility model relates to a transportation semi-trailer, which can conveniently unload materials. The utility model comprises a door seat which is arranged at the bottom of a material unloading bin, and a door cover plate, wherein, the door cover plate is hinged with one side of the door seat. The other side of the door seat is provided with a lock hook, and the middle part of the lock hook is hinged with and supported on a machine frame which is connected with a bin seat. The other end of the lock hook is hinged with a screw rod, and a swinging screw nut which is matched with the screw rod is supported on the machine frame. When the door cover plate is required to be opened for unloading materials, the lock hook is impelled by `the screw rod and the lock hook surrounds a hinge and supporting point to rotate to lead one end of the lock hook to move away from the door cover plate. Then, the door cover plate can smoothly leave by means of the self gravity and the action of goods in a carriage to achieve the purpose of opening for unloading. The utility model has the advantages of reasonable structure, simple manufacturing process, low cost of processing and manufacture, convenient operation, and durability. Consequently, maintenance cost is reduced.
Description
Technical field
But the utility model relates to a kind of conveying semi-trailer of easy-unloading.
Background technology
Conveying semi-trailer Chang Zuowei delivery of bulk material, when goods is transported to the destination, need discharging, the insider offers the many places door unloading feed bin bottom, by the translation door cover plate, make door cover plate leave gate seat, reach the purpose of unlatching, because gate seat is easily stopped up by the loose unpacked material in the compartment, open very inconvenience, particularly when loading contains fluent or tiny material material, for preventing to leak, between gate seat and door cover plate, be provided with sealing member, strengthened resistance especially to the switch animal that parallel-moving type is opened.The middle part with door cover plate that has is convertible to be connected on the gate seat, and this scheme has made things convenient for the open and close door, but in discharge process, door cover plate is easily washed away by goods and weares and teares, and has influenced the service life of door cover plate.
Technical scheme
The utility model purpose is to design a kind of both convenient the unlatching, durable again conveying semi-trailer unload feed bin bottom door switching device.
The utility model comprises and is arranged on gate seat, the door cover plate that unloads at the bottom of the feed bin, door cover plate is hinged on gate seat one side, at the gate seat opposite side latch hook is set, and the latch hook middle part is hinged on the frame that is connected the storehouse seat, the latch hook other end and a screw mandrel are hinged, and the swing nut support that cooperates with screw mandrel is on frame.
When needs are opened the door cover plate discharging, promote latch hook by screw mandrel and rotate around its hinged point, make latch hook one end leave door cover plate, door cover plate can be pushed open smoothly by goods effect in himself gravity and the compartment, reaches the purpose of opening discharging.The utility model is rational in infrastructure, and technology is simple, and the processing and fabricating cost is lower, and is easy to use, durable, thereby maintenance cost is descended.
Again close door cover plate for convenient after discharging, the utility model side sheet room at the bottom of cover plate and storehouse is provided with stay cord, and operating personal need not to pierce and unloads at the bottom of the feed bin, as long as on side plate, make door cover plate return back to gate seat by stay cord, and then the revolution screw mandrel, latch hook is resetted, hook door cover plate.
Simultaneously, the utility model stay cord is connected on the plate of bottom side, storehouse by spring, purpose is to be subjected to hinged some antagonistic force that door cover plate is swung back and forth for preventing to open door cover plate moment after falling fast, cushions so establish spring, thereby door cover plate is guaranteed service life.

Specific embodiment
Face down bonding at the oblique side plate 1 of superimposed trailer envelope bottom bonded assembly connects a support 2, on support 2, connect swing nut 3, in swing nut 3, cooperate screw mandrel 4, the latch hook 6 that the medial end of screw mandrel 4 hinged is turned back, the middle part of latch hook 6 is hinged on the support 2 by bearing pin 5.
By rotating shaft 8 door cover plate 7 is hinged on the outside of gate seat 9 in the relative side of support 2, sealing band 10 is arranged on the periphery in gate seat 9 outsides.
With bottom side, the storehouse plate 1 of support 2 homonymies on be connected spring 13, the lower end of spring 13 connects steel wire tow line 11, the other end of steel wire tow line 11 connects the frame of door cover plate 7 away from rotating shaft 8.Simultaneously, on side plate 1, also be provided with stay cord and mix hook 12.
