The invention also discloses a transport vehicle which comprises the bulk material paving device.

Furthermore, the transport vehicle comprises a conveyor belt type unloading carriage driven by a hydraulic motor, wherein an upturning type rear door is hinged on a rear plate of the conveyor belt type unloading carriage, one end of a hydraulic cylinder is hinged with the rear plate, and the other end of the hydraulic cylinder is hinged with the upturning type rear door; the rear end of the conveyor belt type unloading carriage is fixedly provided with the bulk material paving device.

Furthermore, the width of a feeding port at the upper end of the bulk material paving device corresponds to the width of the conveying belt, and the distance between a distributing port at the lower end and the ground is 10-20 cm.

Compared with the prior art, the invention not only can transport materials, but also can directly carry out paving operation while unloading, and can be widely applied to pavement paving or grain transportation and airing.

Detailed Description

Embodiment 1, as shown in fig. 1 to 3, a bulk material paving transport vehicle includes a conveyor belt type unloading carriage 1 driven by a hydraulic motor 15, an upturned rear door 12 is hinged on a rear plate 11 of the conveyor belt type unloading carriage 1, one end of a hydraulic cylinder 13 is hinged with the rear plate 11, and the other end is hinged with the upturned rear door 12; a spreading hopper 2 is fixedly arranged at the rear end of the conveyor belt type unloading carriage 1, and when the upturning type rear door 12 is closed, the rear end of the conveyor belt type unloading carriage 1 above the conveyor belt 14 is closed; when the flip-up back door 12 is opened, the material of the conveyor belt 14 can fall into the upper end feed opening 21 of the spreading hopper 2. The spreading hopper 2 is in a funnel shape with a narrow upper part and a wide lower part, a thick upper part and a thin lower part, the width of the upper end feeding port 21 corresponds to the width of the conveying belt 14, and the lower end material distributing port 22 is 10-20cm away from the ground. 5 flow distribution plates 23 are fixedly arranged in the paving hopper 2, and the flow distribution plates 23 divide the inner cavity of the paving hopper 2 into 6 small cavities. The distributing plate 24 with the Z-shaped section is hinged to the lower end of the spreading hopper 2, the distributing plate 24 comprises a flat plate part 241, a vertical plate part 242 and an inclined plate part 243, the vertical plate part 242 and the inclined plate part 243 can block or open the distributing opening 22, and the flat plate part 241 is fixedly provided with the vibrator 25.

If the automatic harvester harvests wheat in the ground, the bulk material paving and transporting vehicle provided by the invention is accompanied with the automatic harvester and loads harvested grains into the conveyor belt type unloading carriage 1, after the bulk material paving and transporting vehicle is fully filled, the bulk material paving and transporting vehicle is transported to an airing field of a grain storage warehouse, the upturning type rear door 12 is opened through the control handle in the cab, wheat flows into the paving hopper 2 and is shunted through the shunting plate, and the wheat uniformly flows out from a fine seam between the distributing plate 24 and the distributing opening 22, at the moment, the vibrator 25 and the hydraulic motor 15 are started through the control handle in the cab, so that the conveyor belt 14 slowly rotates, the wheat continuously enters the feeding opening 21, and meanwhile, the transporting vehicle slowly moves forwards, and the wheat is paved into a thin layer on the airing field, so that the wheat is saved in time and labor.
