The utility model comprises a packing case beam hinged on an overturning skip beam, the upper end of the rear door pneumatic switching mechanism is hinged on the rear door of the packing case, and the rear door pin on the lower end of the rear door is fastened to the door hooker. The rear door pneumatic switching mechanism is characterized in that the other end of the door hooker is welded on a rotating shaft arranged on the bottom of the packing case; one end of the rotating shaft is fixedly connected with an adjusting arm which is moveably connected with the pushing rod of a pneumatic thruster via a pin; the pneumatic thruster communicates with an air reservoir of the vehicle body via a main pipeline. Since the door hooker has a large opening moment to effectively open the hooker when air pressure is 6 kg/cm<2>, the opening up force is about 250 kg. A large-scaled unloading vehicle requires longer time for the opening up force for the door hooker, and a pneumatic thruster is arranged on the other side of a rotating shaft.

Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a gas circuit principle scheme drawing of the present utility model.
The specific embodiment:
Reach embodiment in conjunction with the accompanying drawings and describe, but protection domain of the present utility model is not limited to accompanying drawing and embodiment.
Self dumping lorory back door jack pneumatic switch mechanism as shown in the figure, propulsion source is served as by the pneumatic thrust device 8 that existing rear braking subpump on the dumping car makes an end band push rod 7 into, form a cover compressed-air controlled door opening and closing mechanism by push rod 7, rotating shaft 4 and gate stop 3, designed PA-system simultaneously, loud speaker sounding after gate stop is opened, but the unloading of lifting container informed.
It comprises that the upper end is articulated in the back door 2 on the container 1, the keeper of lower end, back door is in tightening state with the gate stop 3 that is welded in the rotating shaft 4, rotating rotating shaft is installed in the lining that welds with container, pull back spring 6 one ends are connected in the return arm end aperture that is welded in the rotating shaft, and the other end is connected the fixedly button hole that is arranged on the container beam 9.One end of rotating shaft is fixedly connected with adjusting arm 5, and adjusting arm 5 is contained on the spline of shaft end by inner spline housing, and locks with spring cotter; Be fixed with on the adjusting arm and make rotating shaft drive the adjusting arm bolt that gate stop rotates.By the movable connection of latch, the pneumatic thrust device is communicated with vehicle body air receiver 14 by main tracheae 10 between push rod 7 other ends on the pneumatic thrust device 8 and the adjusting arm 5.
When wanting the unloading of lifting container, closure is arranged at the electromagnetic gas valve switch 15 in the operator's compartment, and the electromagnetic gas valve door is unimpeded.Pressurized air is by vehicle body air receiver 14 warps
Tracheole 13 and electromagnetic gas valve 12, lead to relay valve 11 and rely on air pressure to make its conducting, the pressurized air in this moment vehicle body air receiver is passed through
Main tracheae 10 lead to pneumatic thrust device 8 and make its work, the push rod on it promotes adjusting arm rotates rotating shaft, drives gate stop 3 and leaves the back keeper, thereby reach the purpose of opening the door.
Pressure when relay valve 11 is unimpeded in its chamber also makes pneumatic switch 17 conductings, simultaneously loud speaker 16 sounding.But the opened lifting container unloading of gate stop is described.If loud speaker is sounding not, chaufeur should ascertain the reason so.Check whether gate stop is opened, if gate stop is not opened, just need to open gate stop with manual methods: the plus-minus screw that turns on the adjusting arm with spanner makes rotating shaft drive gate stop move towards opening direction, opens gate stop, and then lifting container unloading, accomplish really all to guarantee in any case that gate stop effectively opens.Flat container falls after unsnatching goods.Disconnect the electromagnetic gas valve switch, electromagnetic gas valve ends, and relay valve loses servo air pressure and also becomes and end.And air resets the push rod of pneumatic thrust device in the discharge side.Pneumatic switch disconnects, and loud speaker stops sounding.This moment, pneumatic thrust device push rod resetted the back rotating shaft under the tension of returning pull-spring, made gate stop just hook keeper and was in the back door and locks state.
