The lifting device can be a hydraulic cylinder, and two ends of the hydraulic cylinder are respectively connected between the carriage 2 and the vehicle body 1 in a rotating way. When the building soil is dumped, the lifting device turns the carriage 2 upwards so as to dump the building soil to the ground along the bottom surface of the carriage 2.

As shown in fig. 1 and 3, the car 2 includes a bottom plate 22, two side fences 14 and a tailgate 16, and the two side fences 14 are respectively located on both sides of the bottom plate 22 in the longitudinal direction. The end fence 16 is located between the two side fences 14 and is rotatably connected to the upper ends of the side fences 14, while the end fence 16 is located at the end of the side fence 14 away from the head of the vehicle body 1. The tailgate 16 is turned over when the car 2 is tilted. Bottom plate 22 is close to back fence 16 one end and has seted up holding tank 20 along automobile body 1 length direction, and sliding connection has inner panel 18 in holding tank 20, has seted up second spout 21 along seting up on the lateral wall of holding tank 20 both sides, and the equal fixedly connected with in inner panel 18 both sides slides and inlays the slider (not shown in the figure) of locating second spout 21.

When the carriage 2 inclines, one end of the inner plate 18, which is far away from the tailgate 16, slides to the end, which is close to the tailgate 16, along the second chute 21, the tailgate 16 is fixed through the sliding block, and the inner plate 18 extends out of the carriage 2, can bear building soil in the dumping process and simultaneously reduce the distance between the building soil and the ground.

In order to reduce the dust during unloading, a water spraying device is arranged at one end of the carriage 2 close to the head of the carriage body 1, and the water spraying device comprises a water tank 4, a water spraying pipe connected to the water tank 4 and a water pump 3 used for pumping the water pump 3 in the water tank 4 into the water spraying pipe. The spray pipe divides the pipe to become two leading water pipes 5, and leading water pipe 5 wears out side breast board 14, and side breast board 14 outer wall is provided with a plurality of cassettes 7, and cassette 7 sets up leading water pipe 5 in side breast board 14 tail end along side breast board 14 outer wall, and 5 mouths of pipe of leading water pipe towards back breast board 16, and 5 mouths of pipe of leading water pipe department fixed mounting have atomising head 6.

When watering device is started to needs, in water pump 3 pours the water pipe 5 of both sides into with the water in the water tank 4, the water in the water pipe 5 sprays in building soil material through regional through atomising head 6 behind side breast board 14 to carry out the dust fall.

A baffle 13 is fixedly arranged between the two side fence plates 14, and the baffle 13 is positioned at one end of the water tank 4 far away from the head part of the vehicle body 1. The baffle 13 is fixedly connected in the compartment 2 and abuts against the bottom surface of the compartment 2 and the two side fences 14. The height of the baffle 13 is consistent with that of the carriage 2. The end of the baffle 13 far away from the head of the vehicle body 1 is provided with a dust removing device 15.

As shown in fig. 2, the dust removing device 15 includes a first slide groove 19 disposed on the inward side of the two side fence plates 14 along the length direction of the vehicle body 1, and the first slide groove 19 is located on the side of the side fence plate 14 away from the bottom plate 22. A support frame 12 is arranged between the two side fence plates, and two ends of the lower part of the support frame 12 are respectively embedded in the two first sliding grooves 19 in a sliding manner. An exhaust fan 8 is fixedly arranged in the middle of the upper end of the support frame 12. The exhaust fan 8 comprises an air inlet 9 and an air outlet 10, the opening of the air inlet 9 faces the bottom plate 22, the air outlet 10 is arranged at one end far away from the air inlet 9, a filtering cloth bag 11 is arranged at the air outlet 10, and the filtering cloth bag 11 is fixedly connected with the air outlet 12 through a rubber band 19.

When the carriage 2 inclines, the support frame 12 and the exhaust fan 8 on the support frame 12 slide to the end close to the tailgate 16 along the first sliding groove 19, and the air inlet 9 of the exhaust fan 8 aligns with the raised dust and absorbs the raised dust. The raised dust is filtered by the filter cloth bag 11, and then clean gas is discharged, so that the dust removal effect is achieved.

The main working flow is as follows:

before the building soil is poured, the water spraying device is started, the water pump 3 injects running water into the water conduit 5 from the water tank 4, and the water flows out of the spray head 6 and is sprayed to an area to be poured with the building soil. When building soil is required to be poured on the ground, the carriage 2 is turned upwards by the lifting device, and the support frame 12 close to one end of the head of the vehicle body 1 and the exhaust fan 8 on the support frame 12 slide to one end of the carriage 2 close to the tailgate 16 along the first sliding groove 19. And the exhaust fan 8 is opened, the air inlet 9 of the exhaust fan 8 absorbs the raised dust generated by dumping building soil, and the filter cloth bag 11 of the air outlet 10 isolates the raised dust in the filter cloth bag 11, so that the gas discharged from the air outlet 10 is clean. Meanwhile, water flowing out of the spray head 6 is sprayed on the building soil, so that the raise dust is reduced. The inner plate 18 arranged in the bottom plate 22 slides downwards along the second sliding groove 21 until being fixed due to gravity, so that the distance between the building soil and the ground in the dumping process is reduced, and the generation of dust is reduced. After finishing dumping, closing the sprinkling device, simultaneously, lifting device restores the carriage 2 to the initial state, because the carriage 2 is close to the one end of the head of the automobile body 1 and is lower than the one end of the head of the carriage 2 away from the head of the automobile body 1, the support frame 12 and the exhaust fan 8 on the support frame 12 slide to the initial position along the first chute 19 under the action of gravity.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
