The specific embodiment

By Fig. 1 and Fig. 2 as can be seen, of the present utility model have a dumping car that pneumatic movable tail sticks up, comprise wagon box 1, the front portion of wagon box 1 lower end links to each other with jacking apparatus, the postmedian and the chassis 4 of wagon box 1 lower end are hinged and connected, the rear portion of wagon box 1 base plate and the front end of tail seesaw 5 are hinged and connected, the lower surface of tail seesaw 5 is hinged and connected with the top of 3 lifting pins 10 respectively, the bottom of each lifting pin 10 is fixedly linked with the top of air bag 2 respectively, the bottom of each air bag 2 is hinged and connected with the support 14 that is positioned at described tail seesaw 5 belows respectively, and each air bag 2 of rear portion that support 14 is installed in wagon box 1 base plate links to each other with air control unit by gas piping respectively.Support 14 also can be installed in the rear portion of chassis 4.

By Fig. 3 and Fig. 4 as can be seen, has centre hole vertically in above-mentioned each lifting pin 10, the center of each air bag 2 inner bottom part vertically is fixed with pilot bar 11, the top of pilot bar 11 can be inserted in the centre hole of described lifting pin 10 slidably, the top of each air bag 2 is respectively equipped with cover plate 13, cover plate 13 is fixedly linked with the flange that is positioned at lifting pin 10 bottoms, and the bottom of each air bag 2 is respectively equipped with base plate 12, and the lower surface of each base plate 12 is hinged and connected with support 14 respectively.

The quantity of above-mentioned lifting pin 10 and air bag 2 also can be all 2 or 4 or 5 or 6 or 8.

Above-mentioned air control unit comprises pneumatic valve 8, pneumatic valve 8 is fixed on the middle front part of chassis 4, the touch pole of pneumatic valve 8 matches with the lower surface of wagon box 1, the admission port of pneumatic valve 8 links to each other with air pump by air inlet pipe, the air extractor duct of pneumatic valve 8 links to each other with the admission port of each air bag 2 by blowdown pipe 6, and the exhausr port of pneumatic valve 8 links to each other with each air bag 2 exhausr port by freeing pipe 9.

Above-mentioned wagon box 1 comprises the back shield 3 that top and hopper frame are hinged and connected, and the bottom along continuous straight runs of back shield 3 front surfaces is fixed with closing plate 11, and the outside face of closing plate 11 matches with the rear end of tail seesaw 5.

When in the wagon box 1 goods being housed, goods can produce a squeezing action to back shield 3 and tail seesaw 5, making tail seesaw 5 be tending towards upset downwards opens, be tending towards turning over the bottom of seasonal back shield 3 and open, but this moment is because each air bag 2 interior aerificatioies, each lifting pin 10 withstands on the lower surface of tail seesaw 5, makes tail seesaw 5 not overturn and puts down.Unload the goods in the wagon box 1 if desired, when the front end of wagon box 1 is come by jacking apparatus jack-up, can by gas piping the gas in each air bag 2 be discharged with seasonal air control unit, so, tail seesaw 5 will self with and the effect of the thing gravity of getting in stocks under upset downwards, the material in the wagon box 1 will be toppled over out.After the discharged, the front end of wagon box 1 can fall to original position, carries high pressure gas with seasonal air control unit by gas piping in each air bag 2, so each lifting pin 10 will jack-up tail seesaw 5.

If do not need to use tail seesaw 5, also the gas in each air bag 2 can be discharged, make each lifting pin 10 no longer support tail seesaw 5, make tail seesaw 5 be in horizontality and be placed on the carriage 15.

Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design plan prerequisite; common engineering staff make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
